Opis:
In a natural order, man depends on his fellow man because he is a social being. In the order of salvation, God wants the work of redemption to be passed on to other people as well. In the work of the Church, all sacraments and ministries are distributed by his ministers. The Church always cares for the internal development of her spiritual sons and daughters. Spiritual guidance is one of the tools used by the Church. Spiritual guidance is the individual guidance of a Christian on God’s path is a way to teach him to listen to the inspirations of the Holy Spirit and to answer it, and is also a special help in practicing virtues appropriate to the state of life and the current situation. The purpose of this article is to show the value of spiritual direction in the modern world, referring to the history of the church and paying attention to the contemporary context of spiritual direction and certain conditions that are important in undertaking this spir-itual practice.

Opis:
The leading purpose of the spiritual guidance is to deliver a necessary assistance in achieving the sainthood which means the perfection of love. The role of a spiritual director (guide) can be summarized as helping Holy Spirit to form Christ within each member of “Caritas” groups. A spiritual threat, which all volunteers of “Caritas” are exposed to, is an excessive activism which often makes volunteers forget to pray and proceed their spiritual lives. A spiritual director is supposed to control the activeness of a volunteer and make sure that an appropriate balance is maintained. To do volunteering is a chance for the youth to live their lives in a truly Christian way, full of love and care for others. The vocation and mission of volunteers, imbued with the spirit of the Gospel of love, play a special role in building the civilization of love in the modern world.

Opis:
The purpose of this study was to characterize the scope, direction and pace of the evolution taking place in the rural part of highly and less urbanized regions, including without limitation changes to the territorial distribution and percentage of the rural population in the voivodeships covered by this study; the levels of the technical and social infrastructure; the condition of agricultural productive inputs and the level of the farms’ commercial production; the development level of non-agricultural activities in rural areas. The source of information were books, magazines and publications of the Central Statistical Office (GUS). Once collected, the information was processed and interpreted with the use of a vertical and horizontal comparison method, the statistical method and the relative valuation method. It was found that: a) the rural population grows (and so does its share in the country’ population) though rural areas become smaller in size, b) more and more rural areas are transformed into residential areas, improving the level of technical and social infrastructure, c) the Śląsk region is characterized by a slower evolution of the general and rural infrastructure compared to Świętokrzyskie voivodeship, d) the regions covered by this study demonstrate a high decrease rate of agricultural land resources, accompanied by the growth of other productive inputs and of agricultural commercial production, e) rural areas are increasingly engaged in economic activities covered by the REGON register. The characteristics and consequences of entrepreneurship are diversified across the rural areas under consideration. The most positive effects can be noted in Śląsk region.

Artykuł ma cztery części: 1) pojęcie mitu (świadectwo spotkania z Absolutem i narzędzie w odkryciu prawdy egzystencjalnej); 2) przesłanie mitów biblijnych (przeciwieństwa wpisane w naturę ludzką oraz wezwanie do ukierunkowania swego życia na Boga); 3) przekaz mitów perskich (niebezpieczeństwo kłamstwa egzystencjalnego oraz braku decyzji); 4) filozoficzne ujęcie zła (zło jako życie człowieka w chaosie możliwości i braku ukierunkowania swego życia na Boga).
The paper presents the philosophical idea of moral evil in the thought of Martin Buber (†1965) as the lack of direction in the life of a man. The source of inspiration were for the concept of Buber biblical and Persian myths. The paper has four parts: 1) idea of myth (testimony of the meeting with the Absolute and instrument in searching for the existential truth); 2) message of the biblical myths (contradiction in the human nature and appeal to the direction of the life); 3) Persian myths (danger of existential lie and lack of decision); 4) philosophical idea of evil (existance in the chaos of possibilities and lack of the direction in the life to God).

Opis:
The paper deals with sub-evaporite Badenian deposits (Middle Miocene, Paratethys) that display a sudden appearance of globorotaliid taxa showing preferences in the taxonomic set and coiling direction. An interval of sinistrally coiled Jenkinsella mayeri with proportionally coiled Globoconella bykovae is at the bottom of the studied sequence. It is followed by an interval of proportionally coiled Jenkinsella transsylvanica. Proportionally coiled Globoconella bykovae with a small number of proportionally coiled Jenkinsella transsylvanica are at the top of the Moravian (CPN 7) substage (Orbulina suturalis alias Lagenidae Zone). The sub-evaporite part of the Wielician (CPN 8) substage (Uvigerina costai alias Spiroplectammina Zone) began with a globorotaliid-barren interval (IIC biozone). It is followed by biozone IID displaying three globorotallid peaks amongst globorotallid-barren deposits. Only globoconellas are present in all these three events. Proportionally coiled Globoconella bykovae appeared first. It is followed by proportionally coiled Globoconella minoritesta and sinistrally coiled Globoconella bykovae at the end of the biozone IID. Coiling preferences of globorotaliids have been compared to changes in the hydrographic regime unfolding during the CPN 7 and CPN 8 in the studied area of the Paratethys. The study discovers that the coiling of globorotaliids responded selectively to the hydrographic changes. Globoconella bykovae is highly opportunistic and can tolerate considerable temperature changes. Specimens of this taxon persist to coil proportionally during the sub-evaporite Badenian, except for the shift to sinistral coiling just prior to the Wielician evaporites. Sinistrally coiled Jenkinsella mayeri is the most sensitive to hydrographic changes. This taxon retreated at the onset of the temperature drop during the mid-Moravian cryptic cooling. This cooling is marked by the new jenkinsellid occurrence – proportionally coiled Jenkinsella transsylvanica. Proportionally coiled Globoconella minoritesta is present in the middle of the IID globorotaliid peaks. The globorotaliid coiling data, presented in this paper, has been calibrated to the global stratigraphy. The integrated data (foraminifera, nannofossils, oxygen and carbon stable isotopes, radiometric measurements) supports the view that the CPN 7/CPN 8 boundary is coeval to the Langhian/Serravalian one. In the Polish part of the Carpathian Foredeep, the boundary runs within the Skawina Formation.

Opis:
People make different choices depending on which decision is the default option. In intertemporal choices, the default option is typically imposed externally. For example, people expect more for delaying the gain (default in the present) than are willing to pay for accelerating the future gain over the same period (default in the future). We claim that apart from the external default, people’s choices are also influenced by the internal (natural) default such as the time perspective resulting in the reference point in the present. By manipulating the congruency between the internal and external defaults, we show that incongruence between defaults decreases the strength of discounting of gains, but not of losses.

Opis:
The paper presents and discusses a method of azimuth determination of ultrasonic echo arrival in air. The basis of the presented approach is the assumption that the received signal is a narrowband one. In this way, the direction of the signal arrival can be determined based on its phase shift using two receivers. When the distance between the receivers exceeds half of the wavelength of the received signal, a problem of ambiguity in determining the angle of arrival arises. To solve this, a method using multiple pairs of receivers was used. Its robustness and temperature dependence is analysed. The most import ant advantages of the presented approach are simplified computations and low hardware requirements. Experimental data made it possible to show that for strong echoes, the accuracy is higher than 0.5°. In the case of weak echos, it is reduced to about 2°. Because the method is based on phase shift measurement, the ultrasonic sonar that uses this method can be compact in size. Moreover, owing to the theoretical analysis, certain properties of the mutual location of the receivers were found and formally proved. They are crucial for determining proper receivers’ inter-distances.

Opis:
The multi-direction digital moving mask method, employing the superposition of the exposure along various moving directions, is developed for fabricating continuous microstructures. The mask pattern corresponding to each moving direction is determined by projecting the target dose profile in the corresponding moving direction. All the mask patterns are dynamically exposed on the same substrate layer by layer so as to form a 3D profile of the exposure dose. The selection criterion of a quantization number and moving-direction number is discussed. For verification of the multi-direction moving method, experiments are performed to fabricate a square pyramid array and square-based microlens array by moving along two orthogonal directions, and round-based microlens array by moving along six directions.

Wind results from the air in motion. Air in motion arises from a pressure gradient. Wind direction and wind speed are two characteristics of the wind, whose inter-relationships may give us an insight into the prevailing weather condition at a particular place. This study examines the trend analysis of the wind direction and wind speed pattern of Srinagar Garhwal Valley, Uttarakhand. The average wind speed in Srinagar Valley is 2.923± 1.232 m/s. As it is seen the most frequent wind in Srinagar Garhwal has a speed from 0.50 to 2.10 m/s in the northwest direction.

Opis:
Source localization problem consists of an ensemble of techniques that are used to obtain spatial information of present radiation in given medium of propagation, with a constraint of the antenna geometry and the characteristics of radiating sources. This condition gives multitude of cases to study, hence several methods were proposed in the literature. In this paper, a new algorithm for estimating the Direction of Arrival (DoA) of narrowband and far eld punctual sources is introduced. By exploiting the spectrum of covariance matrix of received data, the Lorentzian function on spectral matrix to lter the eigenvalues is applied. This ltering process eliminates the eigenvalues belonging to signal subspace. Parameters of Lorentz function are adjusted using rst and second statistics of eigenvalues. The algorithm requires the knowledge of minimum eigenvalue and is performing when the dimension of antenna is relatively large which is conrmed by several Monte Carlo simulations.

Opis:
Spiritual development has been an important issue in the lives of many people since the dawn of humanity. In order to achieve their goal of greater spiritual maturity, they often asked help from a person they considered to be more spiritually advanced than themselves. With the beginnings of Christianity, this human propensity became even more pronounced and formalized, taking the shape of spiritual guidance in some form, which, over periods of both growth and decline, has recently come to resurgence in popularity. Today, there are also a significant number of people who seek professional help from therapists in resolving psychological issues and who, at the same time, would also like to use their personal spiritual resources to help them reach healing. Thus, a growing need for spiritually integrated psychological counseling has arisen. These developments require a better understanding of both the spiritual processes and the manner of helping people grow spiritually through the door of psychological counseling in some form. This article is a survey of the literature that presents a broad range of models to meet spiritual needs of modern people. Presenting such a variety of approaches is an attempt to widen the scope of what is offered as therapeutic assistance for spiritually sensitive individuals. In the conclusion, the author proposes new modalities for the inclusion of spiritual content in the counseling process.

The average daily values of wind speed and wind gust speed in the years 2001–2018 in Siedlce were analyzed. In the study area, the frequency of individual wind directions was determined and, according to criteria set by the Government Centre for Security, the frequency of hazards from damaging wind gusts was evaluated. The following wind gusts were considered: >20 m/s, 25 m/s and 35 m/s. It was found that, in the Siedlce area, the prevailing wind direction was west-south-westerly (WSW), and the average annual wind speed in the long-term study period was 2.99 m/s. March, April and May were the months when the highest speeds of maximum wind gusts (>35 m/s) were recorded. Extreme wind gusts the speed of which poses a hazard to the environment, national economy as well as human life and health, occurred in both the cold and warm seasons of the year.

In this paper a novel method of the bearing estimation in a passive sonar system with a towed array is introduced. The classical approach of the bearing estimation based on the spatial spectrum is extended by using the synchrosqeezing method that is a part of the reassignment method introduced by Kodera et al. The usage of this method leads to the precise bearing estimation. The proposed method requires a relatively small amount of computation, because of possibility of using the FFT algorithm. Moreover, method immunity against AWGN is tested for a selected sonar array having regard to the direction of arrival and the signal frequency.

Opis:
Three-axis machines are limited in the production of geometrical features in powder-bed additive manufacturing processes. In case of overhangs, support material has to be added due to the nature of the process, which causes some disadvantages. Robot-based wire-arc additive manufacturing (WAAM) is able to fabricate overhangs without adding support material. Hence, build time, waste of material, and post-processing might be reduced considerably. In order to make full use of multi-axis advantages, slicing strategies are needed. To this end, the CAD (computer-aided design) model of the part to be built is first partitioned into sub-parts, and for each sub-part, an individual build direction is identified. Path planning for these sub-parts by slicing then enables to produce the parts. This study presents a heuristic method to deal with the decomposition of CAD models and build direction identification for sub-entities. The geometric data of two adjacent slices are analyzed to construct centroidal axes. These centroidal axes are used to navigate the slicing and building processes. A case study and experiments are presented to exemplify the algorithm.

Alternating Direction Solver
Opis:
This paper deals with the application of an Alternating Direction Solver (ADS) to a non-stationary linear elasticity problem solved with the isogeometric finite element method (IGA-FEM). Employing a tensor product B-spline basis in isogeometric analysis under some restrictions leads to a system of linear equations with a matrix possessing a tensor product structure. The ADI algorithm is a direct method that exploits this Kronecker product structure to solve the system in O (N), where N is the number of degrees of freedom (basis functions). This is asymptotically faster than state-of-the-art, general-purpose, multi-frontal direct solvers when applied to explicit dynamics. In this paper, we also present a complexity analysis of the ADS incorporating dependence on the B-spline basis of order p.

Opis:
The article deals with J.R. Skoyles’s theory of right hemisphere literacy which challenges the paradigm of left hemisphere dominance in the reading process and claims that in the early textual cultures the right hemisphere may have played a dominant role in reading. Applying this theory to Arab-Muslim culture, one would claim that in the early stages of the development of Arabic writing, reading may have been right-hemispheric in nature. The activity of the right hemisphere was related to the direction of writing leftwards. Moreover, Arabic script, whose reading is contextual due to the lack of short vowels, may have involved the right hemisphere to a relatively large extent in its processing and may have fostered the ‘preservation’ of its involvement even after the development of left hemisphere literacy. Finally, the presence of connections between letters in an Arabic word could also stimulate the participation of the right hemisphere in reading. At the same time, the development of left hemisphere literacy, now dominant among native Arab right-handed readers, did not necessarily have to be linked to a change in the direction of writing due to its high status in the culture linking it to the God and His word.

Opis:
This paper discusses the collaboration between the author, Tymoteusz Karpowicz, and the director, Andrzej Witkowski (broken by the latter's sudden death). This artistic alliance had brought forth for theatrical works, prepared by the Wrocław group Teatr Rozmaitości (later renamed as the E. Wierciński Teatr); Witkowski himself made every effort to do it. Owing to Witkowski, the playwright could treat this theatre almost as his own stage. Karpowicz had found in the Wrocław director the most careful and profound interpreter of his plays, someone who noticed in them a new theatrical quality. According to critics, Witkowski ”felt” best Karpowicz's dramaturgical matter. He collaborated with the author and at the same time created his independent and ambitious productions, which made the texts more profound and richer in their expression. This creative alliance was initiated by the preview of The Strange Passenger in 1964. Three years later Witkowski directed The Green Gloves. The latter production was very different from earlier productions in other theatres. It became the most important spectacle of the season and gained a permanent place among the most eminent productions of the director and the Wrocław stage. In the following years there were still other stagings: A Break in the Journey (1968), based on a new version of the text; Witkowski participated in the whole process, and the preview of Charon from Dawn to Dawn (1972).

Opis:
In order to study the heat and moisture comfort, the wicking property of textiles has been used as an important and effective index. In this paper, the wicking behaviour of cotton fabric in the warp and weft directions was investigated in terms of the wicking height, rate of wicking, mass increment distribution per centimetre of the wicking height, and the durative wicking height after removal of the wicking liquid reservoir. The results showed that the wicking height square had a good correlation with the time in both the warp and weft directions. The wicking rate was higher in the weft direction than that in the warp, especially at the beginning of the wicking process. The mass increment of fabric per centimetre of the wicking height was inversely proportional to the wicking height; the mass of water absorbed in the fabric did not have a significant difference in the weft and warp directions.
Badanie właściwości zasysania wody jest ważnym wskaźnikiem wykorzystywanym podczas oceny komfortu cieplnego tkanin. W pracy badano właściwości zasysania wody (efekt knota) tkanin bawełnianych w kierunku wątku i osnowy ze szczególnym uwzględnieniem wysokości zasysania, szybkości zasysania, rozkładu przyrostu masy cieczy na centymetr wysokości zasysania oraz czasu utrzymania się wysokości zasysania po usunięciu tkaniny ze zbiornika z cieczą. Wyniki pokazały, że kwadrat wysokości zasysania jest zależny od czasu, zarówno w przypadku osnowy jak i wątku. Szybkość zasysania jest wyższa w kierunku wątku, w szczególności na początku procesu zasysania. Rozkład przyrostu masy cieczy na centymetr wysokości zasysania był odwrotnie proporcjonalny do wysokości zasysania; nie odnotowano znaczącej różnicy w ilości zaabsorbowanej wody w tkaninie w kierunku wątku i osnowy.

Opis:
Position-based routing protocols are widely accepted efficient solution for routing in MANETs. The main feature of position-based routing protocols is to use greedy forwarding methods to route data. The greedy forwarding methods select a node, either having maximum progress towards destination (distance-based principle) or minimum deviation with line between source and destination (direction-based strategy). The first method minimizes the hopcount in a path and on the other hand, second method minimizes the spatial distance between source and destination. The distance-based routing has a great impact on the selection of reliable node and the direction based routing plays a major role to increase the stability of route towards destination. Therefore, in this paper authors propose a weighted forwarding method, which combines both the selection, schemes to select an optimal next forwarding node in a range. The simulation results show that the proposed scheme performs better than existing position-based routing protocols.

Opis:
Regular fully filled antenna arrays have been widely used in direction of arrival (DOA) estimation. However, practical implementation of these arrays is rather complex and their resolutions are limited to the beamwidth of the array pattern. Therefore, higher resolution and simpler methods are desirable. In this paper, the compressed sensing method is first applied to an initial fully filled array to randomly select the most prominent and effective elements which are used to form the sparse array. To keep the dimension of the sparse array equal to that of the fully filled array, the first and the last elements were excluded from the sparseness process. In addition, some constraints on the sparse spectrum are applied to increase estimation accuracy. The optimization problem is then solved iteratively using the iterative reweighted l1 norm. Finally, a simple searching algorithm is used to detect peaks in the spectrum solution that correspond to the directions of the arriving signals. Compared with the existing scanned beam methods, such as the minimum variance distortionless response (MVDR) technique, and with subspace approaches, such as multiple signal classification (MUSIC) and ESPIRT algorithms, the proposed sparse array method offers better performance even with a lower number of array elements and in severely noisy environments. Effectiveness of the proposed sparse array method is verified via computer simulations.

Opis:
Ice sheet movement in northeastern Poland is reconstructed from analysis of the spatial orientation of glacial landforms and glaciotectonic deformations. The orientations of both positive and negative glacial landforms (morpholineaments) of the Vistulian Glaciation were analysed. These landforms form 4 sets and follow an original crevasse system (joint net) within the ice sheet, probably resulting from horizontal stress exerted as the ice advanced from the north. Esker deposits have been glaciotectonically deformed to form a compressional fan fold, due to limited movement of the ice sheet prior to deglaciation. This movement caused the ice crevasses to be tightened and cut by strike-slip faults. Movement here was from the NNW, as determined from the orientation of deformations. Thus, the ice-flow direction changed at least by 10° during the last phase of the Vistulian Glaciation. If the ice rotated the northeastern portion of the esker, this change may have amounted to 30°.

These aspirations are a kind of response to changes taking place in the company’s environment, thus giving the main direction of strategic activities. decisions as to the choice of the direction of enterprise development therefore concern every type of organization, regardless of their size. in the presented article, the author has attempted to classify the company’s strategy theories in Polish and international literature. The presented comparative research indicates concepts uniquely associated with the strategy: long-term direction in which the company is heading, the scope of the organization’s activities, the organization’s advantage over its competitors, strategic adjustment to the business environment; resources and competences of the organization as well as values and expectations. in this article, the author also points to the difference in the importance of strategy and competition. in the summary, as the result of the conducted research methodology, the author defines that the right choice of strategy is the foundation of the existence of an organization in the sector and creates a sustainable basis for growth in many areas of the company’s operations.

The paper presents the concept of the method of determining the direction of ultrasonic signal arrival, i.e., the azimuth and elevation angles. This method is an extension of the previous approach which was proposed to determine only the azimuth angle. The approach is based on the indirect phase determination. This makes it possible to tolerate spacing of receivers greater than half the wavelength of the received signal. At the same time, it provides increased measurement accuracy and reduced hardware requirements. To check the robustness of the method, simulations were carried out for the geometric arrangement of the receivers of the sonar module, for which the method was then implemented. This sonar module was used in the conducted experiments. The results of these simulations and experiments are included in the paper and discussed.

Purpose: The study aims to identify the main directions of intragroup cooperation, along with crucial areas of cooperation in business groups, and develops theoretical models of cooperation in a business group. Methodology: The qualitative approach is applied in the study that is based on the cross-case analysis of four business groups operating in Poland. Findings: Results indicate that business groups cooperate mainly vertically (cooperation between the core company and affiliates) in operations. Horizontal (among affiliates) and vertical cooperation in other areas – marketing, R&D, finance, and human resources – are not so intense. The study enables us to propose a theoretical framework of cooperation models in business groups based on two dimensions – the direction of cooperation and the number of cooperation areas. It leads to the identification of four models: two-sided loose cooperation, two-sided tight cooperation, multi-sided loose cooperation, and multi-sided tight cooperation. Implications: Identification of main directions of cooperation in business groups, along with areas of cooperation have implications for both researchers and managers. Findings of the study and the theoretical framework of cooperation models in business groups can be used as a basis for the further theoretical exploration of the organization and functioning of business groups in the economy and a strategic decision guideline for managers. Originality: The literature focuses mainly on the interorganizational cooperation between dispersedly owned standalone entities. Studies on intraorganizational cooperation in business groups are limited. The study aims to provide a better understanding of cooperation between entities in business groups

Opis:
In this article, the main parameter of the correlative-interferometric direction finding method with twodimensional correlative processing of spatial signal in the aperture of a linear antenna array (AA) is determined as the value of spatial shift within the AA aperture. The corresponding objective function is also formed. Analytical optimization of this parameter is presented and a comparative analysis of analytical calculations based on simulation results is conducted. In the simulation, a range of dependencies of the middle square deviation of estimation of direction on the value of the spatial shift for a signal-to-noise ratio of 0 dB, for minimum 3-sample and 4-sample Blackman-Harris windows of the spectral analysis, is received. The value of the middle square deviation of estimation of direction will be minimal and will equal 0.02 degrees using a minimum 3-sample Blackman-Harris window with the −67 dB level of side lobes. It offers high noise immunity and high accuracy of direction finding.

Opis:
Numerous Authors of scientific papers occurring in hydrodynamic theory of slide bearing lubrication, up to now almost always had neglected the oil dynamic viscosity variations caused by temperature, adhesion forces, capillary forces, or hydrogen ion concentration across the film thickness by virtue of the statement of the constant temperature as well constant adhesion as capillary forces in the thin bearing gap height direction. In addition, simultaneously by virtue of boundary layer simplifications for energy equation and by virtue of new measurements performed in micro and nano- level follows that oil temperature gradients and its values differences and adhesion or capillary gradients of forces in bearing gap height directions are not negligible small. The contemporary hydrodynamic theory of lubrication for non-isothermal lubricant flow is unfortunately based on the assumption of constant viscosity values across the film thickness, despite abovementioned self-evident contradiction between the fact of constant viscosity and simultaneously temperature variations in gap height direction. Such problem was up to now not sufficient critical examined and explained in practical and theoretical sense. After Authors, knowledge by virtue of above problem the most scientific papers in the domain of non-isothermal and lamellar hydrodynamic slide bearing or biobearing lubrication were up to now not sufficient correctly solved. It denotes that the main hydrodynamic lubrication solutions presenting for example hydrodynamic pressure by the modified Reynolds equation and temperature by the energy conservation equation are not sufficiently correctly obtained and next not correctly solved. Therefore are assumed simultaneously the temperature T and oil dynamic viscosity variations in length, width and bearing gap- height directions. From this assumption follows, that the energy equation must be solved simultaneously with the equations of motion i.e. consequently with pressure equation where viscosity depends on temperature and temperature depends on the coordinate in gap height direction.

Opis:
Praca charakteryzuje związki temperatury powietrza z kierunkami wiatru obserwowanymi na stacji w Hornsundzie w wieloleciu 1978-2009. Na stacji najczęściej wieje wiatr ze wschodu, od 38.3% w czerwcu do 59.4% wszystkich obserwacji w marcu. Subdominuje wiatr z NE (od 5.3% w lipcu do 30.9% w październiku). Przy wiatrach z N, NE i E średnia temperatura powietrza w okresie grudzień-marzec jest niższa od -10°C. Najcieplejsze są wiatry południowe (od -2.4°C w grudniu do 4.5°C w sierpniu). W okresie dnia polarnego (czerwiec-wrzesień) wieloletnie średnie miesięczne temperatury powietrza są dodatnie niezależnie od kierunku wiatru. Występujące na stacji w Hornsundzie wiatry cechują się dużą stałością struktury termicznej. W okresie chłodnym (listopad-maj) 'trwale' ciepłe są wiatry z sektora od W przez SW, S do SE, a 'trwale' zimne są wiatry z N, NE i E. Od listopada do stycznia największy wpływ na temperaturę powietrza w danym miesiącu wywierają wiatry z NE, a od lutego do maja - wiatry wschodnie.
This work characterises correlations between air temperatures and the wind directions observed at the Hornsund station over the many-year period 1978-2009. The wind direction most frequently observed at this station is east and it is noted in 38.3% of all observations in June and in 59.4% in March. NE wind prevails (form 5.3% in July to 30.9% in October). When N, NE and E winds are observed then the mean air temperature in the period December- March is lower than -10°C (from -10°C with E winds in December to -13.3°C with NE winds in January). Warmest are S wind (from -2.4°C in December to 4.5°C in August). During the polar day (June -September) the many-year mean monthly air temperatures are positive regardless of wind direction and in the middle of summer they are characterized by similar values: in July from 4.0°C with winds from SW to 5.1°C with NE winds, in August from 3.5°C with N winds to 4.5°C S winds. Winds occurring at the Hornsund station are characterized by high stability of thermal structures. During the cold (November-May) winds from the sector by W, S to SE are 'permanently' warm and winds from the N, NE and E are 'permanently' cold. From November to January the biggest impact on air temperature in the month have winds from the NE and from February to May - easterly winds.

Opis:
The resolution of a Direction of Arrival (DOA) estimation algorithm is determined based on its capability to resolve two closely spaced signals. In this paper, authors present and discuss the minimum number of array elements needed for the resolution of nearby sources in several DOA estimation methods. In the real world, the informative signals are corrupted by Additive White Gaussian Noise (AWGN). Thus, a higher signal-to-noise ratio (SNR) offers a better resolution. Therefore, we show the performance of each method by applying the algorithms in different noise level environments.

Opis:
Two common channels through which humans communicate are speech and gaze. Eye gaze is an important mode of communication: it allows people tobetter understand each others’ intentions, desires, interests, and so on. The goal of this research is to develop a framework for gaze triggered events that can be executed on a robot and mobile devices and allows to perform experiments. We experimentally evaluate the framework and techniques for extracting gaze direction based on a robot-mounted camera or a mobile-device camera that are implemented in the framework. We investigate the impact of light on the accuracy of gaze estimation, and also how the overall accuracy depends on user eye and head movements. Our research shows that light intensity is important, and the placement of a light source is crucial. All the robot-mounted gaze detection modules we tested were found to be similar with regard to their accuracy. The framework we developed was tested in a human-robot interaction experiment involving a job-interview scenario. The flexible structure of this scenario allowed us to test different components of the framework in varied real-world scenarios, which was very useful for progressing towards our long-term research goal of designing intuitive gaze-based interfaces for human robot communication.

Opis:
This paper describes a method which determines the parameters of an object orientation in 3D space. The rotation angles calculation bases on the signals fusion obtained from the inertial measurement unit (IMU). The IMU measuring system provides information from a linear acceleration sensors (accelerometers), the Earth’s magnetic field sensors (magnetometers) and the angular velocity sensors (gyroscopes). Information about the object orientation is presented in the form of direction cosine matrix whose elements are observed in the state vector of the non-stationary Kalman filter. The vector components allow to determine the rotation angles (roll, pitch and yaw) associated with the object. The resulting waveforms, for different rotation angles, have no negative attributes associated with the construction and operation of the IMU measuring system. The described solution enables simple, fast and effective implementation of the proposed method in the IMU measuring systems

Opis:
The paper concerns the issue of optimum control of the strongly non-linear dynamic system, i.e. Anti-Tank Guided Missile (ATGM). The linear-quadratic regulator (LQR) was used to provide control capabilities. In order to use the classic LQR, the dynamics of the object must be presented in the form of a linear-stationary model. This is not possible in the case of the considered missile, mostly due to mass changing in time (intensive consumption of fuel) and varying aerodynamic conditions depending on the Mach number Ma. Thus, we are dealing with a non-stationary system. Moreover, state variables are frequently involved in complex functions, which do not allow one to separate coefficients related to state variables very easily. In order to linearize such a complex system, the paper uses Jacobian, as the matrix of state, calculated at each time instant. The automatic pilot of the ATGM, using the LQR method, determines the signals controlling the angles of flight control surfaces and the thrust vector using continuously calculated Jacobians. The paper presents the algorithm for the ATGM control.

Praca dotyczy kształtowania się warunków anemometrycznych w czterech miejscowościach województwa warmińsko-mazurskiego, zróżnicowanych pod względem warunków fizjograficznych. Celem podjętych badań była analiza przebiegu warunków anemometrycznych w latach 1991– 2010 pod względem różnych klas prędkości, na podstawie 360-stopniowej róży wiatrów. Uwzględniono także częstość występowania cisz atmosferycznych w badanym okresie. Dane wyjściowe dotyczące średnich prędkości i kierunków wiatru dla stacji meteorologicznych w Elblągu, Kętrzynie, Mikołajkach i Olsztynie uzyskano z IMGW-PIB. Na podstawie analizy warunków anemometrycznych w badanym 20-leciu stwierdzono, że największe średnie prędkości wiatru występowały w Kętrzynie (3,5 m•s-1), a najmniejsze w Mikołajkach i Olsztynie (2,9 m•s-1). Spośród badanych miejscowości w Elblągu przeważały wiatry z kierunku południowego, a w pozostałych miejscowościach z zachodu i południa. Cisze atmosferyczne najczęściej występowały w Olsztynie (7,4%).
This paper describes anemometric conditions in four localities of the Warmińsko-Mazurskie Province of different physiographic conditions. The aim of this study was to analyse the anemometric conditions in the years 1991–2010 in different speed classes based on 360 degree wind rose. Furthermore, the frequency of calms during this period was also calculated. The input data on the average wind speed and direction were obtained from meteorological stations of the Institute of Meteorology and Water Management – National Research Institute located in Elbląg, Kętrzyn, Mikołajki and Olsztyn. Based on the analysis of the anemometric conditions in the analyzed 20-year period it was found that the highest average wind speed was in Kętrzyn (3.5 m•s-1) and the lowest was in Mikołajki and Olsztyn (2.9 m•s-1). Among all studied localities, the southerly winds dominated in Elblag, in other localities westerly and southerly winds were dominating. The largest frequency of atmospheric calms (7.4%) occurred in Olsztyn.

The work presents a description of wind speed and direction in terms of using wind power as a renewable energy source. The wind power in Poland and at the Zawady EF was characterised. Observations were collected from 2002 to 2006 by an automatic meteorological station installed at the Zawady Experimental Farm (EF). Average monthly and yearly frequencies of winds blowing from individual directions were determined, and the average monthly wind speed was analysed. The most frequently recorded wind speed ranged from 2 to 4 m/s (light wind), and the least frequent winds blew at the speed of more than 10 m/s (strong wind). The cold season of the year saw winds blowing at the greatest speed (December, January and February), it being the lightest in the summer months (June, July and August). Wind rose analysis (2002–2006) revealed that at Zawady Experimental Farm, the westerly wind was the most frequent. A wind turbine has a limited capacity of wind power use, so only a small portion of energy supplied by wind may be converted into usable energy.

Opis:
For unconventional oil and gas reservoirs such as shale oil and gas as well as tight oil and gas, hydraulic fracturing generally enhances oil recovery. However, the flowback rate of the residual fracturing fluid is low. The residual fracturing fluid in the fracture or the rock ma- trix can reduce relative permeability of oil and gas, and the production rate will decrease. Therefore, it is necessary to study the factors that affect the flowback rate of the fracturing fluid. Most previous studies used the slot model, and viscous and capillary forces explain stable discharge in porous media. The conclusions were only a primarily qualitative analysis. The factors from experimental studies were not comprehensive, and they did not consider the influence of gravity. There are few studies on unstable drainage in porous media un- der different displacement directions. This paper presents a carboxymethyl hydroxypropyl guar gum fracturing fluid with good temperature resistance, and a fracturing fluid flowback experiment is carried on. The effects of the displacement direction, injection pressure, inter- facial tension, fracturing fluid viscosity, and proppant wettability on the flowback rate are analyzed. The research results can provide formulation of the on-site construction scheme.

Opis:
This paper proposes the usefulness of combining an electromagnetic clutch and brake with a pendulum for antiswing for developing a stabilized wideband pendulum-type gravity direction sensor. The pendulum-type sensor is high in response to direction change but liable to swing even when the change stops, in general. Therefore, anti-swing control without degrading sensitivity of direction measurement is important. Continuous damping of the pendulum motion causes an error in a stationary condition unless the pendulum is free from damping repetitively in an appropriate term. To develop a quick response direction sensor without error, we use a magnetic device. Based on motion analysis of a double pendulum, we simulate behaviours of the pendulum-type sensor by actuating the magnetic device by using different signals in form, frequency and magnitude. Also, we fabricate a motion simulator having two rotation joints to evaluate the anti-swing effect of the magnetic device. In the experiment we demonstrate that the device is beneficial for suppressing pendulum vibration over a wideband for measuring resultant direction of the acceleration compound with motion and gravity on such a platform moving randomly. Also, we show that a triangular signal is better than a sinusoidal signal for making the settling time short; however difference is within a narrow margin.

The contemporary problems of numerical calculations ocurring in powertrain tribology and transport problems demand the more and more exactness for obtained results.Moreover in performed calculations very important is the convergence, stability and reliability of the gained numerical values. The main scientific topic of the presented paper concerns the method of the determination of the optimum net for numerical calculations of partial difference and recurrence equations. The abovementioned optimum difference and recurrence method is referring to the stability of obtained particular and general numerical solutions and assures the convergence process of obtained calculation values. The Unit Net Region (UNR) was assumed at first for Laplace Operator. The optimum of the nod geometry localization was examined at first for UNR. The optimization index is defined and derived for UNR to determine the most useful net among the various geometries of the nods localization during the difference methods performances of partial recurrence numerical calculations. In the next considerations had been proved the corollary, where taking into account the optimum UNR, we can create optimum nets for other numerous partial difference and recurrence equations in discrete spaces. For example the numerous calculation results of presented optimum net for recurrent calculations are applied for numerical solutions of a Reynolds partial recurrence equation with variable coefficients in curvilinear orthogonal coordinates for curvilinear boundary conditions, and for other numerical problems occurring in applied and hydrodynamics.

This paper develops a static model of endogenous task-based technical progress to study how factor scarcity induces technological progress and changes in factor prices. The equilibrium technology is multi-dimensional and not strongly factorsaving in the sense of Acemoglu (2010). Nevertheless, labour scarcity induces labour productivity growth. There is a  weak but no strong absolute equilibrium bias. This model provides a plausible interpretation of the famous contention of Hicks (1932) about the role of factor prices and factor endowments for induced innovations. It may serve as a microfoundation for canonical macro-economic models. Moreover, it accommodates features like endogenous factor supplies and a binding minimum wage.

Opis:
Effects of direct reduction time of vanadium titanomagnetite concentrate (VTCE) on the preparation and photocatalytic performance of calcium titanate were investigated in this study. It was found that extending the reduction time could not only promote the formation of calcium titanate, but also facilitate the reduction of iron minerals in the reduction products. The optimum reduction time was 180min under the conditions of $CaCO_3$ dosage of 18wt%, reduction temperature of 1400℃ and lignite dosage of 70wt%. The reduced iron (Fe grade of 90.95wt%, Fe recovery of 92.21wt%) and calcium titanate were obtained via grinding-magnetic separation. Moreover, calcium titanate prepared via the direct reduction method could be used as a photocatalyst, where the degradation degree of methylene blue increased from 25.13% to 60.14% with the addition of calcium titanate. Furthermore, Langmuir Hinshelwood fitting results indicated that the degradation of methylene blue by the calcium titanate prepared under different reduction times conformed to first-order reaction kinetics, where the photocatalytic degradation rate of methylene blue was noted to be the highest for a reduction time of 180 min.

Opis:
Often regarded as purely utilitarian messages with no artistic value in themselves, stage directions are a neglected aspect of theatre studies. This paper seeks to answer the questions “Who speaks in stage directions? How? To whom?”. Looby examines the nature of the speaker, the addressee and their relationship by examining the evolution of stage directions through Shaw, O’Casey and Beckett. However, the paper concentrates primarily on stage directions in Brian Friel’s Translations, arguing that they have an artistic form and function related to the theme of the play and going beyond mere technical instructions to the production crew.

Opis:
A smart antenna with capability of beam steering in azimuth over a wide frequency band using only spatial signal processing is presented. Filters and tapped-delay networks employed in conventional wideband linear arrays are avoided by using a two-dimensional rectangular array structure. In this array, only constant real-valued weighting coefficients, realized with amplifiers or attenuators, are used to form a desired radiation pattern. In order to estimate direction of arrival of a wideband signal, the MUSIC algorithm in conjunction with an interpolated array technique is applied. In the interpolated array technique, a composite covariance matrix is generated, which is a simple addition of covariance matrices of narrowband virtual arrays, being stretched or compressed versions of a nominal array. A working prototype of this wideband array is presented. Its operation is assessed via full EM simulations and measurements.

Opis:
This paper discusses the relationship between geological structure and drainage network orientation at both a meso-scale and local scale. The Loucka Basin, located at the SE margin of the Bohemian Massif (S Moravia, Czech Rep.), has been selected as the model region for these studies. In the Loucka Basin, the bedrock comprises the metamorphic rocks of the Moldanubicum Group, which are arranged in elongated bands and lenses and are fractured with the dense network of faults. There is no extensive cover of unconsolidated younger sediments in the basin, nor any deep weathering regolith. In these respects, the geological setting is extremely favourable for the quantification of structural features and their correlation with drainage orientation. The degree of correspondence between the direction of drainage network segments and the orientation of such structural features as faults, mylonite zones, thrust-fronts and rock lineations was investigated in five study areas. The third-order streams are those most influenced by structure. The higher the order of stream segment, the weaker the correlation, and the more important the overall inclination of the terrain as a controlling factor in stream flow orientation. However, there is a strong structural control of first order streams in the periphery of the Basin. The structural control of streamflow direction in the Loucka Basin, which is built up with Precambrian metamorphic rocks, varies between 30-50% of the rectified channel length; the upper limit is considered to be the maximum conditioned by a local very high density of various linear structural elements.

Celem opracowania było określenie kierunków produkcji gospodarstw ekologicznych w województwach położonych w południowej Polsce. Do badań wybrano trzy województwa: dolnośląskie, małopolskie i podkarpackie. Badania wykazały, że we wszystkich województwach podstawowym kierunkiem produkcji ekologicznej są uprawy pastewne z łąkami i pastwiskami. Cechą charakterystyczną tych gospodarstw jest jeden rodzaj produkcji ekologicznej. W województwach małopolskim i podkarpackim gospodarstwa ekologiczne dobrze wpisują się w system zrównoważonego rozwoju, a w dolnośląskim nie ma ścisłego związku produkcji zwierzęcej z uprawami pastewnymi.
The aim of the study was to determine the direction of organic farms' production in the provinces located in southern Poland. We selected 3 voivodeships to the study: Dolnośląskie, Małopolskie and Podkarpackie. The research showed that in all voivodeships the main direction of organic production are fodder cultivations including meadows and pastures. One type of organic production is the hallmark of those farms. Organic farms from Małopolskie and Podkarpackie fit well into sustainable development system. In case of Dolnośląskie there is no close relation between animal production and fodder cultivations.

Opis:
Acoustic localization by means of sensor arrays has a variety of applications, from conference telephony to environment monitoring. Many of these tasks are appealing for implementation on embedded systems, however large dataflows and computational complexity of multi-channel signal processing impede the development of such systems. This paper proposes a method of acoustic localization targeted for distributed systems, such as Wireless Sensor Networks (WSN). The method builds on an optimized localization algorithm of Steered Response Power with Phase Transform (SRP-PHAT) and simplifies it further by reducing the initial search region, in which the sound source is contained. The sensor array is partitioned into sub-blocks, which may be implemented as independent nodes of WSN. For the region reduction two approaches are handled. One is based on Direction of Arrival estimation and the other – on multilateration. Both approaches are tested on real signals for speaker localization and industrial machinery monitoring applications. Experiment results indicate the method’s potency in both these tasks.

Opis:
Multi-hole probes are simple and robust device to measurement of flow velocity magnitude and direction in wide range of angles of attack – up to 75°. They become popular as they may be easily use to measurement of unknown flow velocity, while optical methods, like PIV or LDA, require some knowledge about the flow for proper setting of measurement devices. Multi-hole probes are also more lasting in comparison with CTA hot-wire probes, which may be damaged by a dust. A multi-hole probe measures air pressure with one pressure tap on its tip and a few (usually 2, 4, 6 or more) taps on conical or semispherical surface of the probe tip. Based on measured pressures, some non-dimensional pressure coefficients are calculated, which are related to flow velocity direction (i.e. two angles in Cartesian or spherical coordinate system) and magnitude. Finding relations between these parameters is relatively complex, which for years was limiting application of multi-hole probes. The article summarizes methods of multi-hole probes calibration and use, which may be classified as nulling and non-nulling methods or – with other criteria – as global and local methods. The probe, which was presented in the article, was the 5-hole straight probe manufactured by Vectoflow GmbH and calibrated in the stand designed and manufactured at the Institute of Aviation. The local interpolation algorithm has been used for calibration, with some modifications aimed on mitigate of mounting uncertainty, which is related with the non-alignment of flow velocity direction and probe axis Results of calibration showed that the accuracy of presented methodology is satisfactory. The standard measurement uncertainty was assessed for 0.2° for the pitch angle and yaw angle, which is better than accuracy declared by the probe’s manufacturer (1.0°). The measurement uncertainty of the flow velocity is approximately 0.12 m/s, similarly like in manufacturer’s data.

This study investigates the selected properties of the thin Ti coating applied by activated evaporation EB PVD technique. This technique was used for the deposition of Ti thin coating onto inner surface of OKhN3 MFA steel tubes. Deposition process was carried out at temperature 200°C. Conventional type of coatings - monolayer Ti - was analyzed by standard techniques for surface status and quality assessment - coating thickness, chemical composition by EDX analysis, adhesion, hardness, roughness, and growth direction of columns at room temperature. Ti monolayer achieved roughness Ra equal from 0.42 μm to 0.47 μm. The resulting hardness was from 2 GPa to 8.5 GPa depending on the sample location inside the vacuum chamber. Placing of the coated surface also affected the direction of grain growth of Ti coating columns. The angles α of grain growth were found to be from 40° to 60°. Angle α increased two to three times more than the incidence angle β (from 12° to 28°) of evaporated Ti particles. Values of the adhesion measured along the Ti growth direction were mostly higher (up to 10%) or the same as those measured perpendicular to it.

In this paper, we propose a new method for building an environmental map in a self-organizing manner using visual information from a mobile robot. This method is based on a Higher Rank of Self-Organizing Map (SOM ), in which Kohonen’s SOM is extended to create a map of data distributions (set of manifolds). It is expected that the “SOM” is capable of creating an environmental map in a self-organizing manner from visual information, since the set of visual information obtained from each position in the environment forms a manifold at every position. We also show the effectiveness of the proposed method.

W pracy przeanalizowano wpływ kierunkowości, jako jednej z cech struktury geometrycznej powierzchni, na intensywność procesu zużywania elementów par ciernych ze stykiem konforemnym. Opisano cechy warstwy wierzchniej elementów maszyn ze szczególnym wyróżnieniem znaczenia kierunkowości SGP w aspekcie transformacji warstwy wierzchniej. Przedstawiono wyniki badań doświadczalnych, w których jako czynniki wejściowe (niezależne) przyjęto: kąt przecięcia śladów obróbki na próbce i przeciwpróbce (0°; 30°; 45°; 60° i 90°) oraz docisk próbki i przeciwpróbki (300; 450 i 600 N). Miarą zachodzących zmian w badanej parze ciernej ze stykiem konforemnym była masa próbek (jej zmiana) kontrolowana po różnych drogach tarcia; stanowiła ona zatem czynnik wyjściowy (zależny). Na podstawie przeprowadzonych badań stwierdzono, że kąt przecięcia śladów obróbki na próbce i przeciwpróbce ma istotny wpływ na intensywność procesu zużywania. Zużycie jest największe dla kąta 0°, najmniejsze zaś dla kąta 90°. Stwierdzono także, że obserwowane zmiany mają mniejszy gradient dla większych wartości obciążenia próbek. Bezpośrednio potwierdzono w ten sposób istotność wzajemnego usytuowania śladów obróbki na współpracujących powierzchniach, a tym samym, lecz pośrednio – wpływ kierunkowości SGP na intensywność procesu zużywania elementów par ciernych.
The article deals with the influence of texture direction, as one of the structure geometric features, on the intensity of wear process of elements of frictional pairs with conformal contact. Properties of the surface layer of machine elements have been described focusing on SGS direction significance in terms of the surface layer transformation. Experimental tests results have been presented, in which such factors as: the angle of machining trace intersections on samples and countersamples (0°; 30°; 45°; 60° and 90°) and the sample and countersample pressure (300, 450 and 600 N) were accepted as input factors. The mass of samples (its changes) controlled along different friction routes was the measurement of changes occurring in the tested frictional pair with conformal contact. On the basis of carried out experimental tests it was found that the angle of machining trace intersections on samples and countersamples has a significant influence on the intensity of the wear process. Wear is the biggest for angle 0 and the smallest for angle 90. It was also found that the change gradient is smaller for higher values of the sample load. Thus in this way significance of mutual location of the sample traces on cooperating surfaces has been proved and at the same time, though indirectly, the influence of SGS direction on the intensity of the frictional pair element wear process.

Opis:
Urban regions are well known to be warmer than the outlying surrounding regions: this phenomenon is termed an Urban Heat Island (UHI). Depending upon its severity, an UHI can influence human health, the condition of urban vegetation, as well as air and water quality leading to a general decline in the living conditions of the affected urban environments and residents. Some studies have shown that prevailing weather conditions, like wind patterns, can influence UHI magnitudes. These studies suggest that wind speeds may be inversely related to UHI magnitude. However, long-term and high frequency weather and temperature measurements are exceedingly rare, so the exact nature of the relationship between wind speeds and directions as well as UHI magnitudes remain unknown. In order to address this problem, this study investigates how UHI magnitudes in five Australian cities affect wind speed and wind direction. The results of this study revealed that urban–non-urban temperature differences are most pronounced under calm weather conditions. The UHI intensity weakened as wind velocity increased: strong significant negative correlations were found between the mean UHI intensity and mean wind speed magnitudes. The results show that the greatest UHI intensities are recorded when wind is weak (less than $2 ms^{-1}$), while the lowest magnitudes are found when wind speeds exceed $6 ms^{-1}$. Further, the results show that the critical wind speed value, above which the strength of the UHI is considerably minimized, is around $4–5 ms^{-1}$. In addition, the study shows that wind direction in each city is a critical driver factor that determines the intensity of the UHI effect. When winds originate from dry environments, they favour high UHI intensities at all wind speeds, while the winds from the ocean side of coastal cities tend to cool urban regions, reducing UHI intensities or even promoting the urban cool island formation.

Opis:
Artykuł jest teologiczno-duchowym komentarzem do publikacji Daniela-Ange’a (ur. 17 X 1932 r. w Brukseli), na temat homoseksualizmu i pomocy duchowej ludziom o skłonnościach homoseksualnych. Główne jego myśli zostały opublikowane w książce Homosexuel qui es-tu? Où vas-tu? (Homoseksualisto kim jesteś? Dokąd podążasz? (rok wyd. we Francji: 1992r.). Dzisiaj, kiedy dyskusja na temat tzw. „nieheteronormatywności” staje się coraz bardziej gorące, jego myśl, oparta na wielu rozmowach i korespondencji z homoseksualistami, wydaje się bardzo istotna. Daniel-Ange proponuje pomoc tym dziewczętom i chłopcom, którzy wbrew sobie odczuwają skłonności homoseksualne, którzy czynią heroiczne wysiłki, by się im nie poddać i marzą o normalnym życiu seksualnym. Wspomniany Zakonnik postuluje, by z wielkim szacunkiem odnosić się do wszystkich potrzebujących pomocy, proponuje im duchową drogę wzrostu: 1. poznania swojej godności w Bogu; 2. odkrycia przyczyn homoseksualizmu; 3. pełniej pokoju twórczej pracy nad sobą; 4. dojrzewania w prawdziwej miłości – w Bogu. Artykuł przytacza konkretne porady duchowe o. Daniela-Ange’a i ukazuje je w świetle współczesnych dokumentów Kościoła.
The article is a theological and spiritual commentary to the publication of Daniel Ange (born on 17th October 1932 in Brussels) on homosexuality and spiritual aid to people with homosexual inclinations. His main thoughts were published in the book Homosexuel qui es-tu? Où vas-tu? (Homosexual Who Are You? Where Are You Heading To?), which appeared in France in 1992. Today, as the discussion about the so-called "non-heteronormativity" becomes more and more heated, his thought, based on a great deal of conversations and correspondence with homosexuals, seems to be crucial. Daniel-Ange offers to aid those girls and boys who have inclinations towards homosexuality in defiance of their selves, and who make heroic efforts not to give up, and dream of a normal sex life. The author advocates that all those in need of aid be treated with great respect, and offers them a spiritual way of growth: 1. to know their dignity in God; 2. to discover the causes of their homosexuality; 3. to work creatively on themselves in peace; 4. to mature in true love - in God. The article sets forth specific spiritual advice of Fr. Daniel Ange, and demonstrates it in the light of contemporary Church documents.

Opis:
The head loss is a decrease in compressive height caused by friction and direction changes of flow at the sliced bend. This method expected to provide is easy, fast, and economical. The elements of influence are the velocity of flow, the number of slices, average length of sliced walls, angle changes of the sliced, coefficient of friction, acceleration of gravity, and slope of the pipe. Equation for coefficient of head loss (Kb) is an analysis method for the head loss (hL) calculation. The analysis results that have obtained are the larger diameter of the pipe, and the more slices with a fixed discharge, the coefficient of hL becomes small. Conversely, if the diameter of the pipe is getting smaller, and the slice is getting less, then the coefficient of hL becomes bigger. This method, expected to give new knowledge in pipeline network applications, especially for the large diameter of pipelines.

Opis:
Structure characteristics of rock and orebody in deep borehole are obtained by borehole camera technology. By investigating on the joints and fissures in Shapinggou molybdenum mine, the dominant orientation of joint fissure in surrounding rock and orebody were statistically analyzed. Applying the theory of metallogeny and geostatistics, the relationship between joint fissure and lode’s extension direction is explored. The results indicate that joints in the orebody of ZK61borehole have only one dominant orientation SE126° 68°, however, the dominant orientations of joints in surrounding rock were SE118° 73°, SW225° 70° and SE122° 65°, NE79° 63°. Then a preliminary conclusion showed that the lode’s extension direction is specific and it is influenced by joints of surrounding rock. Results of other boreholes are generally agree well with the ZK61, suggesting the analysis reliably reflects the lode’s extension properties and the conclusion presents important references for deep ore prospecting.

W referacie przedstawiono zakres wykorzystania ruchomych stacji pomiarowych, w jednym z ustawowych zadań Urzędu Komunikacji Elektronicznej jakim jest gospodarka zasobami częstotliwości [1]. Omówione zostały w nim zarówno zagadnienia pomiarów sygnałów radiowych zgodnych z odpowiednimi zaleceniami Międzynarodowej Unii Telekomunikacyjnej (zwanej dalej ITU) [2] jak i procesy monitorowania i lokalizowania źródeł sygnałów radiowych ze szczególnym uwzględnieniem nowatorskiej metody radionamierzania w ruchu.
The paper presents the scope of using mobile monitoring stations in one of the statutory duties of the Office of Electronic Communications (UKE) in the field of the frequency resources management. An overview of the basic parameters and control functions of a monitoring station is presented in Section 2. The available types of measurements with appropriate ITU recommendations are described. An example of a correct and incorrect result of the radio signal measurement based on the difference of the percentage distribution frequency deviation (Figs. 1, 2) is given in Section 3. The use of an adaptation mask in the process of spectrum monitoring is described in Section 4. Its efficiency is demonstrated by comparing the actual frequency spectrum with that generated before and the saved envelope of this frequency spectrum. Three modes of direction finding are reviewed: the stationary direction finding, the synchronized direction finding and the especially innovative method of mobile direction finding. The mobile direction finding method is based on an advanced mathematical analysis of all potential bearings (Fig. 5). It enables direction finding of many radio sources whose signals are present in the same radio channels simultaneously. It enables limiting the searching area to one or several zones and makes the accuracy of the direction finding least dependable on the precision of direction finding equipment and on the shape of a monitoring vehicle.

In this interview acclaimed director Declan Donnellan, co-founder of the company Cheek by Jowl, discusses his experience of performing Shakespeare in Europe and the attendant themes of cultural difference, language and translation. Donnellan evokes his company’s commitment to connecting with audiences globally. He keeps returning to Shakespeare, as his theatre enables the sharing of our common humanity. It allows a flesh-and-blood carnal interchange between the actors and the audience which directly affects individuals. This interchange has significant consequences in terms of translation and direction.

Opis:
Odebranie sygnałów mikrofalowych oraz wyznaczenie ich parametrów jest źródłem informacji o emitującym je urządzeniu nadawczym. Do podstawowych charakterystyk wykrytych sygnałów mikrofalowych zalicza się: częstotliwość nośną oraz kąt nadejścia. W Zakładzie Mikrofal Instytutu Radioelektroniki WEL WAT opracowano model urządzenia umożliwiającego wykrycie oraz określenie kierunku na nadajniki radiolokacyjne i telekomunikacyjne. Urządzenie to pozwala również na pomiar parametrów sygnałów emitowanych przez te nadajniki. Pomiar kąta nadejścia sygnałów jest realizowany metodą fazową. Chwilowa wartość częstotliwości określana jest przy użyciu mikrofalowego dyskryminatora częstotliwości. System antenowy składa się z czterech dwugrzbietowych anten szerokopasmowych. Umożliwia to pomiar kąta nadejścia sygnałów zarówno w płaszczyźnie elewacji, jak i w azymucie. Urządzenie może służyć do rozpoznawania sygnałów prostych oraz złożonych. Średni błąd pomiaru częstotliwości był mniejszy niż ± 0,2 MHz, a jego wartość maksymalna nie przekraczała ± 0,5 MHz w całym zakresie mierzonych częstotliwości. Kierunek nadejścia sygnału określany był z dokładnością ± 0,2° w całym paśmie pracy.
The paper concerns a device designed for reconnaissance of the electromagnetic space. The presented device determines an angle of arrival (AOA) and immediately evaluates frequency of a received microwave signal. The angular segment of the instantaneous surveillance is 44 degrees in width. The device works within the frequency band from 0.75 to 1.25 GHz. It contains four-element antenna array, direction finding DF channel and instantaneous frequency measurement IFM channel. This structure performs so-called single-pulse phase method of direction of signal arrival and frequency estimation. The microwave parts of both these channels were printed onto a single substrate. This appliance is controlled by the computer which stores calibration data and takes them into consideration in the process of evaluation of the frequency and the direction of incoming microwave signals. This set has been successfully used for recognition of various signals emitted by close and remote electromagnetic sources. The achieved average error of the frequency estimation was ± 0.2 MHz, and maximum frequency error did not exceed ± 0.5 MHz. The accuracy of the angle of arrival determination was better than 0.2 degrees. The presented model of the device has been developed for observation of some segment of the space. To obtain all around instantaneous scanning it is necessary to appropriately place several such devices. The device can intercept simple microwave signals and the signals with LFM, FSK, and PSK modulation as well. The device architecture and experimental results are presented.

Opis:
Analysis of the orientation of both positive and negative glacial morpholineaments (crevasse landforms) was performed on the areas coveredby 12 selectedmap sheets of the Detailed Geological Map of Poland, scale 1:50 000, situated in NE Poland. Axes of these landforms formanet composed of four conjugate sets. This isaclassicaljointnet developeddue to horizontal stress, and composed of an orthogonal (extensional) system consisting of longitudinal and transversal sets, and a rhomboidal (shear) system consisting of two diagonal sets. Based on the orientation of glacial morpholineaments, inherited after the originaljoint net in the ice body, ice sheet advance directions - averaged for the area - were determined. This method of reconstructing ice flow direction creates new possibilities of making synthetic regional analyses, in particular in terms of Pleistocene palaeogeographic investigations. The best potential for the method’suse lies in areas of young post-glacial relief. In the region of NE Poland analyzed, these investigations enabled determination of different directions of ice flow within the Mazurian, Warmian and Vistulian ice sheet lobes of the last glaciation. Local changes in ice sheet movement directions were identified, and these reflected basement elevations (e.g. the Wiżajny Elevation). In other cases, basement irregularities influenced the opening of separate crevasse sets (e.g. outside of the Góra Dylewska massif) giving rise to a dominance of individual directions (sets) in the morpholineament orientation. This method can also be used in geological mapping.

Wykazano, że na przełomie lat 60. i 70. w architekturze pojawiły się nowe, awangardowe kierunki, które doprowadziły do przezwyciężenia tradycji modernizmu i minimalizmu i stały się nowym międzynarodowym „językiem” architektury, nadającym się dla różnych warunków naturalnych, kulturowych i historycznych.
This article investigates the current directions of architecture that result from the introduction of advanced information technology, philosophical and aesthetic ideas to the design. It is shown that at the turn of 1960-1970s in architecture there appeared new avantgarde trends, that led to overcoming of modernism and minimalism traditions and became the new international language of architecture, suitable for a variety of natural, cultural and historical conditions.

Opis:
The concept of equivalence, despite the criticism it has received in the past decades, remains a useful framework for the study of correspondence between legal terms. In the present article, I address the question of direction-asymmetric equivalence in legal translation, i.e. equivalence that does not obey the “one-to-one” principle, and which usually implies that the translator’s decision-making is more difficult in one direction than in the other. This asymmetry may be triggered by intrinsic semantic characteristics of legal terms (synonymy and polysemy), by differences between legal systems (system-specific terms, the procedures used for their translation and their handling in lexicographic sources, competing legal systems, tension between cultural boundedness and neutrality), or by social factors (L1 vs. L2 translation). The instances of directional asymmetry discussed are illustrated with examples from French and Czech.

In this paper usability of state estimation of machine elements surface layer in diagnostic process of technical object state was analyzed. The parameters of surface layer which determine its characteristics and properties also were discussed. The results of initial investigations realized on test stand, designed and made for this aim, were presented too. These experiments concern influence of texture direction parameters of surface geometric structure on the run of service generated layer transformation of kinematical pair elements with conform contact. These parameters are important factors which determined surface layer state. Obtained results confirm significance of tested factors on intensity of wear.

This paper concerns the issue of the partial discharge (PD) sources location using acoustic emission transducer arrays technique and the high resolution direction of arrival estimation technology. In addition to the theoretical assumptions of both techniques, the simulation result, in which an uniform linear array (ULA) was used for registration of the acoustic emission signals generated by defects in power transformer insulation system were shown. To estimate the direction of arrival (DOA) of acoustic signals, that propagate from the discharge-generating defect to the transducer array installed on transformer tank, Multiple Signal Classification (MUSIC) algorithm was chosen. With the ability to locate multisource discharges (even at very low signal-to-noise ratio - SNR), the adopted solution has advantages over conventional techniques.

The article deals with one of the types of the Polish contemporary theatre - the theatre of artistic experiments which, in spite of its niche character, has a fundamental importance for the Polish culture and is one of its major foreign ambassadors. The author has attempted to give an overview of this kind of theatre by classifying different sorts of experimental practices undertaken by Polish theatre artists in their work, including examples from recent productions of the most renowned of them. The diversity of the theatre life in our country coupled with its permanent development as well as the limited size of this article, the methodology adopted and the inevitable subjectivity with regard to the analyzed phenomenon have led to this classification being not entirely complete and absolutely scientifically objective. Instead, it shall be treated merely as a starting point for a comprehensive research in this subject matter.

The work presents the results of experimental study on the possibilities of determining the source of an ultrasonic signal in two-dimensional space (distance, horizontal angle). During the research the team used a self-constructed linear array of MEMS microphones. Knowledge in the field of sonar systems was utilized to analyse and design a location system based on a microphone array. Using the above mentioned transducers and broadband ultrasound sources allows a quantitative comparison of estimation of the location of an ultrasonic wave source with the use of broadband modulated signals (modelled on bats’ echolocation signals) to be performed. During the laboratory research the team used various signal processing algorithms, which made it possible to select an optimal processing strategy, where the sending signal is known.

Opis:
In the recent years, additive manufacturing became an interesting topic in many fields due to the ease of manufacturing complex objects. However, it is impossible to determine the mechanical properties of any additive manufacturing parts without testing them. In this work, the mechanical properties with focus on ultimate tensile strength and modulus of elasticity of 3D printed acrylonitrile butadiene styrene (ABS) specimens were investigated. The tensile tests were carried using Zwick Z005 loading machine with a capacity of 5KN according to the American Society for Testing and Materials (ASTM) D638 standard test methods for tensile properties of plastics. The aim of this study is to investigate the influence of printing direction on the mechanical properties of the printed specimens. Thus, for each printing direction ( and ), five specimens were printed. Tensile testing of the 3D printed ABS specimens showed that the printing direction made the strongest specimen at an ultimate tensile strength of 22 MPa while at printing direction it showed 12 MPa. No influence on the modulus of elasticity was noticed. The experimental results are presented in the manuscript.

This paper presents a prototype measurement system, that will be used for localization of acoustic emission sources originating from partial discharges (PD). It is based on sensor arrays technology and direction of arrival estimation algorithms. Acoustic signals will be received with a universal linear array (ULA) of sensors, wherein the sensory elements are microphones operating in the audible frequency range. For the estimation of the direction of arrival of these signals conventional beamforming algorithm is used which has also been described theoretically. Ultimately, the system will be used to determine the direction of arrival of the acoustic signal generated by the insulation defect, which is corona discharge.

The research described in this paper is centred around the small spa village of Goczałkowice-Zdrój (German: Bad Gottschalkowitz), located in the south of Poland, in the Silesian Voivodeship, the Pszczyński poviat, and the Goczałkowice- Zdrój commune. Along with the rise in the importance of the tourist services sector – including spa services – the tourist product of this tourist town has become the subject of a complex analysis and evaluation in the context of adapting it to the requirements of the market and the needs of consumers, as well as indicating directions for its development. In order to be successful on the national and international tourist market, as well as stay ahead of their competitors, Polish spas should adjust their policies to the needs and determinants of the contemporary market, providing a proper product – preferably an individualised and integrated one, sufficient for the challenging triple-segmented (patient, patient-tourist, tourist) market.

Opis:
Evidence from Art (History), perceptual psychology, and (psycho-)linguistics support the claim that in Western culture (or rather within left-to-right writing languages), people depict or visualize more important or salient figures to the left. However, linguistics studies investigating this topic almost exclusively use active sentences with standard Subject-Verb-Object (SVO) syntax as stimuli, where the subject takes the role of an agent. However natural language exhibits much more syntactical variation. To determine if this pattern is also present when the less common syntax is used, we asked native German, Spanish, and Czech speakers (N=300) to draw situations representing ten sentences varying in syntactic structure. These drawings, simplified versions of the mental representation of the situation, provide a glimpse into the conceptualization of the scenes. The spatial placement of the agent figures in the sentences was coded. Results show that although the asymmetrical effect is strong in prototypical SVO sentences, where the subject has the function of an agent and the object a function of a patient, the effect is weaker or disappears in passive sentences, where the subject at the first position is a patient and object on the second position is an agent, as well as in topicalized (OVS) sentences. Furthermore, we found cross-linguistic differences, which suggests that the character of the bias is language-specific. We postulate that placing the agent to the left is only one of the factors influencing spatial placement. The other factor playing an important role is the naming order.

Opis:
Introduction: The aim of the study was to examine relationships between power of the lower limb and agility, speed, and change of direction (COD) deficit in professional female soccer players. Material and methods: Thirty-three elite Polish Extraliga league soccer players (aged 22 ±5 years; body height 166 ± 4 cm; body weight 58 ± 8 kg) performed the following fitness tests: lower limb muscle power (Leg Press, Half Squat, Counter Movement Jump), straight linear speed (SLS 20 m), and COD speed ( Zig-Zag test, COD deficit). Using the median value as a reference, the players were subdivided into two groups (n=17; n=16) according to their LP, HS 60% 1RM, CMJ (High values below median = stronger group and Low = weaker group ). Results: The COD deficit was calculated as the difference between the 20m speed and the Zig-Zag test. The stronger group was better than the weaker group in SLS 20m (p<0.05; ES=1.23; 0.83; 0.93), but in the Zig-Zag agility test, the difference in the results was not statistically significant (p>0.05; ES=0.48; 0.34; 0.34) and this affected the COD deficit, which was higher (p<0.05; ES=0.9; 0.73; 0.72). The most important finding was that the stronger group had a higher COD deficit and its improvement (reduction) occurs only if the results of the agility test are improved (through agility training) [Ydeficit All groups=0.10+0.87* 20m - 0.83* Zig-Zag]. Increasing power (HS, LP) lead to the improvement in SLS p<0.05, not to COD abilities. Conclusion: This can be useful for coaches during agility training and to improve COD deficit in soccer players and women in general.

Opis:
During the years 1989-1991, after a deep transformation of the internal system and the international order in Europe, Poland pursued a sovereign foreign policy. The new policy had the following general goals: 1) to develop a new international security system which would guarantee Poland's national security; 2) to gain diplomatic support for the reforms conducted in Poland, including primarily the transformation of the economy and its adaption to free market mechanisms, which were designed to result in economic growth; and 3) to maintain and increase the international prestige of Poland and the Poles, who had been the first to commence the struggle to create a democratic civil society in the Eastern bloc. Implementing this new concept of foreign policy, Poland entered the Council of Europe in November 1991. The following year, Warsaw started to strive for membership of NATO, which was achieved in March 1999. A few years later, Polish leaders pursued policies in which Poland played the role of a "Trojan horse" for the USA. This was manifested most clearly during the Iraqi crisis of 2003, and in the following years, particularly in 2005-2007. From spring 1990 Poland aspired to integration with the European Community; in December of the following year it signed an association agreement, which fully entered into force in February 1994. In the period 1998-2002 Poland negotiated successfully with the European Union and finally entered this Union in May 2004. In subsequent years Poland adopted an Eurosceptic and sometimes anti-EU position. The new Polish government, established after the parliamentary election of autumn 2007, moved away from an Eurosceptic policy and pursued a policy of engagement with European integration.

Opis:
Renzo Piano twierdzi, że era rozlewających się miejskich peryferii już minęła. Dywany płasko rozciągających miejską tkankę tarasowych domostw ekspansywnie rozbudowujących infrastrukturę techniczną są zbyt kosztowne i wyniszczające, a system jako taki musi przejść do historii. Jedynie dogęszczające wysokościowce – miasta wertykalne wykorzystujące brownfields, czyli miejskie obszary niezabudowane, mogą sprostać potrzebie ekspansji budowlanej o charakterze "implozji", czyli dośrodkowego rozwoju miast. Rysuje się zatem tendencja rugowania zabudowy podmiejskiej, satelitarnej, nawet wiejskiej, na rzecz intensywnych skupisk miejskich i możliwie nieskażonej natury wokół. Gdzie zatem ulokować atawistyczną ludzką potrzebę "wiejskiej ciszy" – mieszkania pośród drzew, potrzeby stałego kontaktu z przyrodą, trwogi wysokości, w końcu umiłowania bezpiecznej skali "małych miast" zgodnej z tendencją ruchu citta slow. Z drugiej jednak strony coraz bardziej rysuje się niedostosowanie współczesnej populacji do samodzielności przetrwania i konfrontacji z nieograniczoną naturą. "Przygoda" nabrała wymiaru sportowego wyczynu, aktu bohaterstwa, śmiertelnego wyzwania.
Renzo Piano is of the opinion that the era of the sprawling urban peripheries is over. The vast flat areas of terraced houses stretching expansively the urban tissue and the technical infrastructure are too costly and crippling to the economy and the whole system has to pass into history. It is only the dense high-rise buildings – vertical cities making use of the so called brownfields that is the urban un-built up areas, that may satisfy the need for the construction boom that has the character of an "implosion" that is a centripetal development of cities. Thus, one observes a trend to eradicate suburban, satellite and even rural architecture in favor of intensive urban housing and the possibly uncontaminated nature around. Therefore where is the place for the atavistic human need for "rural peace" – for living among the trees and for permanent contact with nature and the fear of heights; and finally what about the love of the safe scale of "small cities" which is in accord with the tendency of the "citta slow" movement. Yet on the other hand, one notices an ever greater lack of adjustment of the contemporary population to being able to survive on one’s own and confront unbounded nature. "Nature" has acquired the dimension of a sports achievement, an act of heroism and a lethal challenge.

Artykuł podejmuje problematykę dobrej wiary w aspekcie regulacji art. 58a Ordynacji podatkowej, wprowadzającej dodatkowe zobowiązanie podatkowe związane z przepisami antyabuzywnymi – klauzulą przeciwko unikaniu opodatkowania. Autorka, dokonując analizy normatywnej instytucji dobrej wiary z art. 58a Ordynacji podatkowej jako przesłanki mogącej uwolnić podatnika od dodatkowego zobowiązania podatkowego, rozważa znaczenie tego pojęcia oraz jego relację w odniesieniu do orzeczniczej koncepcji dobrej wiary funkcjonującej w obszarze wspólnego systemu podatku od wartości dodanej. Wskazuje również, że z uwagi na niedookreśloność terminu „dobra wiara” stanowi ona elastyczną formę stosowania prawa podatkowego, właściwą dla neopozytywizmu prawniczego.
The article addresses the issue of good faith in the aspect of the regulation of Article 58a of the Tax Ordinance, introducing additional tax liabilities related to anti-abusive provisions – a clause against tax avoidance. The author, making a normative analysis of the institution of good faith under Article 58a of the Tax Ordinance, as a prerequisite for freeing the taxpayer from additional tax liability, considers the meaning of this concept and its relations in reference to the jurisprudence of the concept of good faith functioning in the common system of value added tax. She also points out that due to the indeterminacy of the term good faith, it is a flexible form of application of tax law, inherent in legal neopositivism.

Opis:
A review of the Miller, Laue and direction indices characterization was made. Excluding or allowing non-coprime indices, depending on whether the lattice is primitive or centred, were compared. The solution of the “spacing counting problem for centred lattices was proposed. It was shown that for centred lattices: (1) Laue indices nh nk nl can represent not only n-th order diffraction on (hkl) planes, but also the first order diffraction from a family of planes (nh nk nl); (2) “integral reflection conditions” are necessary, but not sufficient for the existence of given Miller indices. “Integral reflection conditions” for Laue indices hkl and other “conditions for Miller indices” (hkl) were distinguished. It was shown that in the case of centred lattices, the inference based on the value of n obtained from the equation of lattice planes, may not be correct. The homogeneity of the centred reciprocal lattices has been clarified. “Simple cubic cell with a base” as a choice of unit cell proposed by “general rule” was contrasted with: “unit cell, if not centred, must be the smallest one”. “Integral reflection conditions” for Laue indices and other, new “conditions for Miller indices”, resulting from transformation of centred lattices to unconventional primitive ones have been proposed. Examples of the not correct use of indices in the morphology and diffraction pattern descriptions were shown.

Opis:
Dwu-letnie badania przeprowadzone w rzeczywistych warunkach eksploatacyjnych nieogrzewanej i nieizolowanej termicznie obory dla 120 krów umożliwiły rozpoznanie pól temperatury w gruncie pod posadzką i w otoczeniu oraz określenie kierunków strumieni cieplnych. Stwierdzono brak analogii pól temperatury i kierunków strumieni cieplnych w stosunku do budynków ogrzewanych. W zimnych porach roku ciepło zakumulowane w gruncie jest oddawane do pomieszczenia, a latem grunt jest odbiornikiem nadmiaru ciepła z pomieszczenia. Ustalono, że właściwe miejsce dla izolacji termicznej „stanu zerowego” to pionowa powierzchnia fundamentów.
The paper presents the results of two-year studies conducted in real operating conditions of a non-insulated and unheated barn for 120 cows. As a result, it was possible to determine temperature fields in the ground beneath the floor and around the building, as well as to define heat flux directions. It was concluded that there is no analogy between temperature fields and heat flux directions with the heated buildings. In colder periods of the year, the heat accumulated in the ground is emitted to the inside of the building; in the summer, the ground absorbs the excess of heat from the building. The final conclusion was that the foundations should be insulated vertically.

Opis:
One reason for failure of fan is suppression to float a shaft’s bearing in the bearing housings. As a result of this disorder leads to blocking axial displacement of bearing, thrust to the growth of the forces acting on the bearing, and then to his accident. The article deals with the identification of the symptoms of this condition in the data from diagnostic measurements and presents the results of practice.
Jedną z przyczyn awarii wentylatora jest uszkodzenie podpory łożyska w jego obudowie. W wyniku tej awarii dochodzi do osiowego zablokowania łożyska, wzrostu sił osiowych działających na łożysko, a następnie do jego zepsucia. Artykuł jest poświęcony identyfikowaniu symptomów tego stanu w danych pochodzących z pomiarów diagnostycznych oraz prezentuje wyniki badań empirycznych.
