Opis:
We construct two examples of infinite spaces X such that there is no continuous linear surjection from the space of continuous functions $c_p(X)$ onto $c_p(X)$ × ℝ$. In particular, $c_p(X)$ is not linearly homeomorphic to $c_p(X)$ × ℝ$. One of these examples is compact. This answers some questions of Arkhangel'skiĭ.

Opis:
Alphaviruses belong to the worldwide distributed Togaviridae family and Alphavirus genus. They are spherical, enveloped, single-stranded RNA arthropodborne viruses. Alphaviruses are mostly transmitted by mosquitoes (Aedes spp. and Anopheles spp.) and are geographically distributed in restricted areas where appropriate vectors are present (Fig.1.). The most recognized members of this genus are Sindbis (SINV), Semliki Forest (SFV), Venezuelan equine encephalitis (VEEV), Ross River (RRV), and Chikungunya (CHIKV) viruses. Alphaviruses are infection agents for humans and many animals. Clinically, most human infections with arthritogenic alphaviruses are associated with symptoms such as fever, headache, joint pain, rash, chronic arthritis, and encephalitis. Major events during the alphaviral infection are virus entry, replication, assembly, and budding of new virions. Alphaviral RNA encodes four nonstructural and five structural proteins. Nonstructural proteins are mainly involved in the replication process and virus pathogenesis, while structural proteins form new virions. Both groups of viral proteins are produced as single polyproteins which undergo autoproteolytic maturation. This process is carried out by the two viral proteases, cysteine protease nsP4 and C protein serine protease (CP), and is considered to be critical for virus replication. The capsid protease CP is a chymotrypsin-like serine protease with the catalytic triad including His145, Asp167, and Ser219. What is important, after a suicidal autoproteolytic event the side chain of Trp267 remains bound in a hydrophobic S1 pocket thus inhibiting further trans-proteolytic activity. Alphaviral capsid protein undergoes a single proteolytic reaction before maturation and then, after selfinactivation, it assembles to form a viral capsid shell. Inhibitors of the capsid protease have significant antiviral activity. Compounds belonging to this group can be good candidates for new antiviral drugs.

Opis:
Mózgowe porażenie dziecięce to zespół objawów wynikających z trwałego uszkodzenia mózgu, znajdującego się w stadium niezakończonego rozwoju. Lokalizacja uszkodzenia mózgu warunkuje deficyty różnych funkcji, np.: ruchu, wzroku, mowy, funkcji poznawczej i emocjonalnej. Międzynarodowa Klasyfikacja Funkcjonowania, Niepełnosprawności i Zdrowia (ICF) to skala opracowana przez Światową Organizację Zdrowia (WHO), przeznaczona do opisu różnych aspektów zdrowia. ICF zapewnia standardowy język i koncepcyjne podstawy do zdefiniowania i pomiaru zdrowia i niepełnosprawności. ICF integruje najważniejsze modele niepełnosprawności. Uznaje rolę czynników środowiskowych w tworzeniu niepełnosprawności, a także znaczenie warunków zdrowotnych i ich skutków. Wieloprofilowość oraz uniwersalność klasyfikacji ICF umożliwia szerokie jej zastosowanie m.in. jako narzędzia: statystycznego, badawczego, klinicznego, polityki społecznej, edukacyjnego. Klasyfikacja ICY-CY (ICF wersja dla dzieci i młodzieży) pokazuje, że dziecko należy traktować jako istotę „międzysystemową”, ponieważ w trakcie rozwoju potrzebuje nadzoru oraz wsparcia we wszystkich aspektach życia, m.in. w sferze poznawczej, społecznej, mobilności, komunikacji, korzystając jednocześnie z kilku systemów usług, m.in. medycznych, edukacyjnych, opieki społecznej itp. Z listy 1685 kategorii ICF-CY specyficznych zestawów dla dzieci/młodzieży powstał kompletny, składający się ze 135 kategorii, specyficzny zestaw ICF-CP dla dzieci z mózgowym porażeniem dziecięcym od 0 do 18 lat. Dla ułatwienia w praktyce klinicznej ICF-CP został podzielony na mniejsze zestawy, również zależne od wieku dziecka z m.p.dz. Diagnoza funkcjonalna ICF-CP, obejmująca wszystkie aspekty życia, ułatwia wyznaczenie celów SMART oraz zaplanowania holistycznego procesu rehabilitacji. Usprawnianie ma na celu w równym stopniu oddziaływanie na naukę funkcji ruchowej, poznawczej, wychowania czy kształtowania osobowości dziecka. Funkcjonalna diagnoza pokazuje relacje rodzinne oraz wpływ środowiska na aktywne uczestnictwo dziecka. System Nauczania Kierowanego to wieloprofilowy proces, polegający na jednopłaszczyznowym, równoległym, zintegrowanym i zharmonizowanym usprawnianiu wszystkich niezbędnych funkcji dziecka z mózgowym porażeniem dziecięcym. Nadrzędnym celem wieloprofilowego usprawniania jest przejście od dysfunkcji do ortofunkcji, czyli według ICF-CP aktywnego uczestnictwa.
Cerebral palsy (CP) is a set of symptoms that result from permanent damage to an undeveloped brain. The location of the brain damage determines the deficits of different functions, which may include: movement, vision, speech, cognitive functions, and emotional functions. The International Classification of Functioning, Disability and Health (ICF) is a scale developed by the World Health Organization (WHO) that is used to describe various aspects of health. The ICF uses a common language and provides a conceptual basis for defining and measuring health and disabilities. The ICF also integrates the most important models of disabilities. It takes into account the role of environmental factors in the development of a disability and the importance of health conditions and their impact. The ICF classifications are multi-profile and universal, which allows for their wider use as a statistical, research, clinical, socio-political and educational tool. The ICF-CY (a version of the ICF for children and youth) shows that a child should be treated as an ‘intersystematic’ individual, because during development a child needs supervision and support in all aspects of life, including in the cognitive, social, mobility and communication spheres, and should take advantage of several services such as medical, educational and social care. From a list of 1685 categories in the ICF-CY, a specific set for children/adolescents with cerebral palsy (the ICFCP) was developed. This consists of 135 categories for children aged 0 to 18 years. For ease of clinical use, the ICF-CP is also divided into smaller sets that are dependent on the age of the child with CP. The ICF-CP functional diagnosis, which takes into account all aspects of life, facilitates the setting of SMART goals, as well as the planning of a holistic rehabilitation process. The aim of rehabilitation is equally aimed at motor functioning, cognition, learning and personality development. a functional diagnosis therefore shows the relationships in the family, and the effect of the environment on a child’s active participation. Conductive Education is a multi-profile process consisting of single-plane, parallel, integrated and harmonised improvement of all functions that are vital for a child with cerebral palsy. The main objective of this multi-profile rehabilitation is to progress from dysfunction to ortho-functioning, which, according to the ICF-CP, constitutes active participation.

This brief discusses the challenges and employs a novel charge-pump and a PFD/CP linearization technique to improve the performance of a 403MHz fractional-N PLL. Techniques are proposed to improve the linearity of the PLL by forcing the PFD/CP to operate in a linear part of its transfer characteristics, while the charge-pump minimizes the current mismatch between the up and down currents by using feedback. The circuit is designed in 0.13jim CMOS process and consumes a total power of 2.6mW. The simulation results show that the synthesizer has a phase noise of-128dBc/Hz at 1MHz offset.

Opis:
Cross in the Jesus’ preaching in commonly interpreted neither as a symbol or as post-Eastern projection produced by Christian community. Similarly the figure of Jesus’ helper, Simon of Cyrene, is frequently interpreted as symbolic one, as the dramatic repetition of Jesus’ indications for his disciples. In this study we try to explain the possibility of real (not symbolic) meaning of the disciple’s cross in the Gospels. We present the texts about cross and disciples divided into three groups: Matt 16, 24 (par. Mark 8, 34; Luke 9, 23), Matt 10, 38 (par. Luke 14, 27), Matt 27, 32 (par. Mc 15, 21; Luke 23, 26). Our analysis of these texts offers the possibility of understanding the preaching of Jesus as eschatological self-revelation of the Lord of Life. In the pericope about Simon we see the historical narrative with relevant information about the members of primitive Christian community presented by Marc. In Luke’s version we recognize the literary rearrangement of this fact in the compatibility with the Jesus’ teaching about disciple’s cross.

Opis:
Niestety, do dzisiaj nie udało się znaleźć odpowiedniej metody obliczania poziomu dobrobytu całego społeczeństwa, jego wzrostu, a jednak dokonuje się na podstawie PKB analiz i wyciągania niekiedy nieodpowiednich wniosków. Proponowana miara Bogactwa Narodu CP Country’s Prosperity uwzględnia między innymi korzyści osiągnięte przez podmioty w gospodarce (przepływy pieniężne), niezależność energetyczną, niezależność paliwową, wskaźnik przyrostu populacji, wartość innowacji oraz wskaźnik poziomu energii odnawialnej. Proponuje się zastąpienie dotychczasowej miary – produkt krajowy brutto PKB miarą Country’s Prosperity CP. Wzrost w czasie danej miary oznaczałby faktyczny rozwój danej społeczności, gdyż nie tylko uwzględnia obecnie trwającą erę innowacji cyfrowych, ale również konieczność rozwoju integralnego z przyrodą. Nowego znaczenia nabiera również wskaźnik niezależności energetycznej, który w dobie zamachów terrorystycznych i wojen w krajach Bliskiego Wschodu i Afryki staje się nierozerwalnie związany ze standardem i poziomem życia danego państwa. Zastosowanie zaprezentowanej miary wymaga wyceny innowacji istotnych dla rozwoju społecznego i bezpieczeństwa danego kraju – metodami dyskontowymi. Celowe byłoby wprowadzenie uproszczonej sprawozdawczości przepływów pieniężnych przez wszystkie podmioty prowadzące działalność gospodarczą. Zebranie danych o nadwyżkach Cash Flow osiągniętych przez podmioty na terytorium kraju jest niezbędnym warunkiem do zastosowania miary CP Country’s Prosperity.
Unfortunately, today failed to find an appropriate method of calculating the level of prosperity of the whole of society, and its growth, however, is made based on GDP analysis and draw the wrong conclusions sometimes. The proposed measure of the Nation Wealth – CP Country’s Prosperity respects the benefits achieved by the company (cash flow), energy independence, the independence of the fuel, the rate of population growth, the value of innovation and the level indicator of renewable energy. It is proposed to replace the current measure – gross domestic product GDP – another measure – Country’s Prosperity CP. The increase in CP mean the actual development of the community as it not only considers the currently ongoing era of digital innovation but also the need for integral development with nature. The new importance the rate of energy independence, which in the era of terrorist attacks and wars in the Middle East and Africa becomes inextricably linked with the standard and the standard of living of the country concerned. It is included in this model. Using the presented measures requires the use of discount valuation methods to innovation relevant to social development and the security of the country. It would be worthwhile for a simplified reporting of cash flows for all the businesses. Gathering data on surplus cash flow generated by the entities on the territory of the country is a prerequisite to the application of measures of CP Country’s Prosperity.

Multicollinearity often occurs in regression analysis. Multicollinearity is a condition of correlation between independent variables which is a problem. One method that can overcome multicollinearity is the LASSO (Least Absolute Shrinkage and Selection Operator) method. LASSO is able to help to shrink multicollinearity and improve the accuracy of linear regression models. Estimators of LASSO parameters can be solved by the LARS (Least Angle Regression and Shrinkage) algorithm by algorithm which calculates the correlation vector, the largest absolute correlation value, equiangular vector, inner product vector, and determines the LARS algorithm limiter for LASSO. Selecting the best model using the Mallow’s C_p statistics. The smallest Mallow’s C_p value will be selected as the best model. LASSO method with a more detailed procedure with LARS algorithm and selecting the best model using the Mallow’s C_p statistics is discussed in this paper.

The paper presents the declarative approach to design of a reference model aimed at project prototyping. The reference model contains the finite set of decision variables, their domains and linking those constraints, i.e. can be seen as a kind of Constraint Satisfaction Problem. Consequently, the model considered can be treated as a knowledge base specifying both a class of enterprises and the projects that could be conducted on their base. So, the model provides a platform for rapid prototyping of alternative versions of project scheduling. The routine queries can be formulated in the straight or reverse way. In that context, the proposed reference model can be implemented in constraint programming (CP) techniques

In the study the author ponders over the possibility and motives of dispensation from divine law. In order to do it he presents the current practice concerning dispensation from divine law, gives the definition of dispensation, the notion of divin law and the motives for dispensation. He concludes by stating that Church has the obligation to retain divine law. However, Church was entrusted with divin law to interpret and apply it. Church is supposed to preach, develop and specify divine law, which it does in specific historical circumstances helping the faithful to gain insight into it. In particular situations, for the spiritual sake of the faithful Church grants dispensation from this law, simultaneously referring to it. Dispensation from divine law is also realisation of God`s law.

Opis:
A real matrix A is said to be completely positive (CP) if it can be decomposed as A= B BT, where the real matrix B has exclusively non-negative entries. Let k be the rank of A and Phik the least possible number of columns of the matrix B, the so-called completely positive rank (cp-rank) of A. The present work is devoted to a study of a general upper bound for the cp-rank of an arbitrary completely positive matrix A and its dependence on the ordinary rank k. This general upper bound of the cp-rank has been proved to be at most k(k + 1)/2. In a recent pioneering work of Barioli and Berman it was slightly reduced by one, which means that Phik \leq k(k + 1)/2-1 holds for k \geq 2. An alternative constructive proof of the same result is given in the present paper based on the properties of the simplex algorithm known from linear programming. Our proof illuminates complete positivity from a different point of view. Discussions concerning dual cones are not needed here. In addition to that, the proof is of constructive nature, i.e. starting from an arbitrary decomposition A= B1 B1T (B1\geq 0) a new decomposition A= B2 B2T (B2\geq 0) can be generated in a constructive manner, where the number of column vectors of B2 does not exceed k(k + 1)/2-1. This algorithm is based mainly on the well-known techniques stemming from linear programming, where the pivot step of the simplex algorithm plays a key role.

Opis:
Przeprowadzono ilościową analizę składu fazowego wybranych stali konstrukcyjnych. Badania wykonano na próbkach dylatometrycznych ze stali typu DP i CP. Wyniki pomiarów stereologicznych na zgładach trawionych różnymi odczynnikami zestawiono z analizą dylatometryczną. Opracowano własny program do identyfi kacji parametrów numerycznych modeli przemian fazowych w stalach. Podjęto próbę opracowania numerycznego modelu przemian fazowych zachodzących w stali konstrukcyjnej wielofazowej z wykorzystaniem nowego oprogramowania.
Quantitative analysis of phases was carried out in some structural steels. The investigation was performed on dilatometric specimens of DP and CP steels. The results of quantitative analysis of microstructure, revealed on specimens using different etching techniques, were compared to volume fractions of phases estimated using dilatometric technique. Moreover, computer program was developed for identification of parameters of mathematical model describing phase transformations in steels. The software was applied to developed numerical model of phase transformations occurring in complex phase structural steel.

Opis:
X-ray crystallography is the natural choice for macromolecular structure determination by virtue of its accuracy, speed, and potential for further speed gains, while synchrotron radiation is indispensable because of its intensity and tuneability. Good X-ray crystallographic diffraction patterns are essential and frequently this is achievable through using the few large synchrotrons located worldwide. Beamline time on these facilities have long queues, and increasing the efficiency of utilization of these facilities will help in expediting the structure determination process. Automation and remote data collection are therefore essential steps in ensuring that macromolecular structure determination becomes a very high throughput process.

Opis:
In this study, production possibility of glass and glass-ceramic produced from granite was investigated. The composition of granite based glass bath mixture was 50 wt% granite, 25 wt% dolomite and 25 wt% sodium carbonate. Composition that was grounded and mixed in a ball mill for 2 h was melted at 1500C for 1 h. Glass samples were heat treated for crystallization to produce glass-ceramic materials at 800°C, 900C and 1000C for 2 h to promote internal crystallization. Phase identifications of glass and glass-ceramic materials were investigated by X-ray diffraction analysis. Moreover, hardness and fracture toughness measurement of glass and glass-ceramic materials were applied. Granite based materials after that melting and casting process was found amorphous state by characterization with X-ray diffraction analysis. After the heat treatment processes, crystal phases settled out in glass matrix were also determined in granite based materials. Moreover, values of hardness and fracture toughness increasing were detected by heat treatment schedule.

Purpose: The aim of the publication was to visualize the process of creating knowledge on the example of the CP Factory production line. For this purpose, the data contained in the relational databases and data of the operating production line were used. This data was converted to the form required by the CogniPy environment to create a semantic ontology for product personalization. Design/methodology/approach: With the available software based on ontologies and knowledge charts, the possibility of common human-computer reasoning has been opened, especially in production management. Findings: During the activities carried out, the on-conceptualization of the knowledge contained in the production management system was brought to an ontological form. At the moment, the information contained in the database is not very different from the data existing in the relational database. However, further modeling of ontology can be directed towards the creation of rules, logic and axioms of production processes. Practical implications: The operations and transformations performed presented the operation of CogniPy in the process of creating ontology and materializing the graph and queries. The created ontology takes the form of a universal set of knowledge that makes it open to wide integration with other systems. Originality/value: The publication shows the possibilities of using the CogniPy environment in the construction of ontology and semantic product personalization.

The central party organs dealt with all issues of the internal and foreign policy of the republic, led the national economy, public organizations, and personnel policy. Therefore, the documents of the ‘special folders’ of the Central Committee of the Communist Party (b) Kazakhstan reflect various spheres of the life of the republic, which for a long time were not available to researchers due to the highest secrecy stamp imposed. The article deals with one of such areas of the problem – the settlement of Kazakh repatriates and representatives of other nationalities from China, who left during the civil war, collectivization, famine and repressions, who, unable to withstand the attitude of local residents and the persecution of the authorities of the country, republic or regions to which they moved, returned back to Kazakhstan. The ways of solving problems related to their settlement in Soviet farms, organization of trade with them, their cultural services, medical care, their resettlement, maintenance and veterinary services for their livestock are analyzed. Authors describes the reasons and measures to prevent the mass return of "nomads" back to China, despite all the decisions taken, the measures taken by the leadership of the republic in connection with the gaps made by some representatives of local authorities during their placement.

Instead of this, the orthorhombic structure with the space group Cmmm was found. The zero-field specific heat was measured in the temperature range 2-300 K. The data were analyzed using the sum of the phonon, electronic, and magnetic contributions to specific heat, respectively. The magnetic part of the specific heat can be well described using the Schottky formula for the 9 crystal-field singlet levels of the pz3 H4 ground-state multiplet of the $Pr^{3+}$ ion.

Opis:
Celem artykułu jest ukazanie wzajemnych relacji między liturgią a pobożnością ludową, szczególnie w okresie średniowiecza. To zwłaszcza w tym okresie nastąpiło rozbicie jedności misterium paschalnego w umysłach wiernych. Efektem przemian religijno-kulturowych dokonujących się w wiekach średnich było powstanie pobożności pasyjnej, mniej teologicznej, bardziej nastawionej na emocjonalne przeżywanie relacji z Chrystusem.
The main purpose of this article is to show the relationship between the liturgy and popular piety especially in the Middle Ages. Particularly at that time the unity of Paschal Mystery was broken up in the faithfull’s minds. Due to the religious and cultural changes in the medieval period the passion devotion was born as less theological form of experiencing the relationship with Jesus Christ focused more on its emotional aspect.

Opis:
One of the actual challenges in tissue engineering applications is to efficiently produce as high of number of cells as it is only possible, in the shortest time. In static cultures, the production of animal cell biomass in integrated forms (i.e. aggregates, inoculated scaffolds) is limited due to inefficient diffusion of culture medium components observed in such non-mixed culture systems, especially in the case of cell-inoculated fiber-based dense 3D scaffolds, inside which the intensification of mass transfer is particularly important. The applicability of a prototyped, small-scale, continuously wave-induced agitated system for intensification of anchorage-dependent CP5 chondrocytes proliferation outside and inside three-dimensional poly(lactic acid) (PLA) scaffolds has been discussed. Fibrous PLA-based constructs have been inoculated with CP5 cells and then maintained in two independent incubation systems: (i) non-agitated conditions and (ii) culture with wave-induced agitation. Significantly higher values of the volumetric glucose consumption rate have been noted for the system with the wave-induced agitation. The advantage of the presented wave-induced agitation culture system has been confirmed by lower activity of lactate dehydrogenase (LDH) released from the cells in the samples of culture medium harvested from the agitated cultures, in contrast to rather high values of LDH activity measured for static conditions. Results of the proceeded experiments and their analysis clearly exhibited the feasibility of the culture system supported with continuously wave-induced agitation for robust proliferation of the CP5 chondrocytes on PLA-based structures. Aside from the practicability of the prototyped system, we believe that it could also be applied as a standard method offering advantages for all types of the daily routine laboratory-scale animal cell cultures utilizing various fiber-based biomaterials, with the use of only regular laboratory devices.

Opis:
The way enterprise capabilities are used decides about its competitiveness among other ones. In that context modeling aimed at production tasks allocation planning plays a crucial role especially at concurrently executed production orders. The introduced reference model employing constraint programming (CP) paradigm describes both an enterprise and a set of project-like production orders. Moreover, encompassing consumer orders requirements and available production capabilities, the model provides the formal framework allowing one to develop a class of decision support systems aimed at interactive production process planning subject to multiproject environment constraints. In that context our contribution is a knowledge-based and CP-driven approach to resource allocation assuming precise character of decision variables. The conditions sufficient for deadlock avoidance are the main goal. The conditions delivered provide formal framework for developing a task oriented Decision Support Tool for Project Portfolio Prototyping (DST4P, Banaszak 2006). The tool provides a prompt and interactive service to a set of routine queries formulated either in straight or reverse way.

Opis:
We assessed the influence of nine biopesticides on adults and larvae of western flower thrips (WFT), Frankliniella occidentalis (Pergande) and its predator, the anthocorid Orius laevigatus (Fieber) under Mediterranean greenhouse conditions. Trials were carried out in a strawberry crop where both species had naturally established. Foliar sprays were applied weekly for one month. Treatments did not provide sufficient control of larval and adult F. occidentalis. The negative effects on the dynamics of the predator were evident only with the use of some specific products. The botanical insecticides rotenone and neem, and the nematode Steinernema feltiae (Filipjev) reduced O. laevigatus numbers, and these effect are evident in the adult stage of O. laevigatus. Such products have determined a reduction of the population of the predator from the first treatments even if the incidence was not very high. We conclude that the use of some botanical pesticides and nematodes against WFT is uneconomical and possibly disadvantageous where there is an established predator-prey population.

Opis:
Odwołując się do skarbca kościelnej tradycji, Sobór Watykański II podjął proces reformy liturgii i korektę tekstów kultowych, by nadać im charakter orędzia, wzywającego uczniów Chrystusa do ożywienia wiary oraz pobudzającego ich moc chrześcijańskiego ducha, która gwarantuje większą owocność uczestnictwa w sprawowaniu kapłańskiej posługi Kościoła. Teksty liturgiczne i święte obrzędy inspirują modlitwę i życie chrześcijańskie, stanowiąc jednocześnie przez przyświadczenie wiary formę obiektywnego uczestnictwa w Paschalnej Tajemnicy Chrystusa. Dzięki temu sam świadomy i pełny udział w liturgii prowadzi do syntezy wiary i życia. Powyższy cel jednak może być osiągnięty przez wydobycie i udostępnienie wiernym i samym liturgiom całego bogactwa treściowego liturgii. Dlatego, zdaniem ks. prof. Kopcia, w realizowanej obecnie odnowie posoborowej, po edycji zreformowanych ksiąg liturgicznych, konieczne staje się otwarcie skarbca ubogaconej liturgii zarówno przez poprawne i pobożne sprawowanie samych obrzędów przy użyciu języka ojczystego, jak i wszechstronne ukazanie wątków treściowych, mogących pobudzać wiarę uczniów Chrystusa do świadomego przyjęcia i przeżycia misterium obecnego i działającego Pana .
Relying on the treasury of ecclesiastical tradition, the Second Vatican Council ventured a liturgical reform and a revision of cult texts, so as to change them into an appeal that inspires the disciples of Christ to enliven their faith, to raise their Christian spirit and to guarantee their more fruitful participation in the ministerial service of the Church. Liturgical texts and sacred rites are inspiration for prayer and Christian life. They also are assent of faith through objective participation in the Paschal mystery of Christ. In this way, conscious  and complete participation in the liturgy leads to the synthesis of faith and life. However,  this objective can only be attained through the discovery and opening of the whole treasure of the liturgical legacy to the faithful, and through introducing it to liturgical texts. This is why Rev. Prof. Kopeć claimed that for the success of the ongoing post-Council reform and re-edition of liturgical texts it was necessary to enrich the liturgy by appropriate and devout service in native language, in order to highlight the ideas that could reinvigorate the faith of Christ’s disciples to consciously accept and experience the mystery of the present and acting God.

The author of the text conducts the analysis of the concrete case and states that new bishop of diocese is able to start the procedure of pastor removing before establishment of new presbyteral council. Appointed by the previous council, the group of people among which bishop selects two pastors for consultation purpose, is still valid, even thought vacant see was declared. Considering the above, the bishop of diocese before taking possession of diocese can remove the pastor, because salus animarum preponderates above the rules of law, which prohibits such action. His decision will be valid.

Opis:
Purpose: The primary purpose of the study was the metallurgical characterization of laser welds. The weldability of commercial production of pure titanium and titanium alloy (CP-Ti) has also been examined. Design/methodology/approach: In this research, the laser fibre method was used to weld sheets of pure titanium, and then microscopy and scanning electron microscopy were used to study the changes in the microstructure, the depth of weld penetration and the width of the weld area with changing welding parameters. Findings: The results proved that increasing the laser power significantly increases the depth of weld penetration and weld width. When the heat input is increased, the shape of the weld pool changes from a V shape to an hourglass shape. It was also observed that the depth of the crater formed increases with the increase in the laser power due to the increase in the melting and evaporation of the weld metal. Increasing the welding speed also has a negative impact on the weld geometry because it reduces the heat input and absorption of laser energy by the weld metal and thus reduces the melting of the metal. The microstructure of the fusion zone consists of acicular α. Fine grains formed in the weld centre at low heat input; the granules became columnar-like. Since commercially pure titanium contains a small amount of beta-phase stabilizers, the cooling rate is extremely high for martensite to occur. Research limitations/implications: In the future, it is recommended to study the effect of changing welding parameters on the mechanical properties of pure titanium because of its great importance in industrial and medical applications. Originality/value: Studying the effect of changing laser power and welding speed on the metallurgical properties of pure titanium, and consequently its effect on the mechanical properties of welds.

Opis:
Based on previously discovered forbidden values of the c/a ratio, we studied anomalies in the temperature evolution of the lattice parameters (a, c) of several hexagonal RTAl compounds at high temperatures (above room temperature). The compound $ErNi_{0.45}Cu_{0.55}Al$, that seemed to be impossible to be prepared in single-phase form, reaches the single-phase state at temperatures above 493 K (220°C). On the other hand, the compound $TbNi_{0.7}Cu_{0.3}Al$ - that was expected to undergo a first-order structural phase transition at high temperatures - exhibits a second-order type transition when approaching the critical values of the c/a ratio. These results are in agreement with idea of a forbidden range of c/a values in these compounds.

Opis:
We have reported the fabrication of MgO core/$SnO_2$ shell nanowires, by a two-step evaporation process. Thermal annealing induced changes in morphology, in which the nanowire surface became rough by the agglomeration of $SnO_2$ shell layers and its crystallinity was enhanced. It was found that three fundamental modes (475, 634, 772 $cm^{-1}$) and an infrared (IR)-active mode (682 $cm^{-1}$) of rutile $SnO_2$ appeared in the Raman spectrum of MgO core/$SnO_2$ shell nanowires. By thermal annealing, the relative intensity of the $A_{2u}$ to the $A_{1g}$ line was reduced, presumably due to the disorder or size effects.

Opis:
The Ce-based 2:3:9 series of compounds are known for strongly correlated 4f-electron behaviour. Here, we report for the first time a study of the thermal conductivity κ(T) in zero and 9 T magnetic field for Ce₂Ru₃Ga₉ across the temperature range 2 K ≤ T ≤ 300 K. The zero-field temperature dependence of κ(T) exhibits a pronounced maximum, characteristic for metals with large electronic mean free path and towards room temperature κ(T) starts behaving in a manner usually attributed to the enhanced electron-phonon coupling. Based on the Wiedemann-Franz law the electronic and lattice contributions to the thermal conductivity were estimated. In high temperature region a distinct step-like anomaly at T* = 203 K has been observed which signals a putative phase transition, probably of phononic or lattice origin. We furthermore discuss the effect of applied magnetic fields on the thermal transport in Ce₂Ru₃Ga₉.

Opis:
Czystsza Produkcja to rodzaj przyjaznej dla środowiska strategii zarządzania przedsiębiorstwem. Skierowana jest ona nie tylko do przedsiębiorców, ale także do jednostek samorządu terytorialnego. Jej zastosowanie ułatwia zarządzanie organizacją ukierunkowaną na zrównoważony rozwój. Organizacje decydujące się na dobrowolne wdrożenie strategii CP nieustannie dążą do zmniejszenia zanieczyszczenia, zmniejszenia zużycia energii i kosztów związanych z opłatami środowiskowymi, poprzez opracowywanie i wdrażanie tzw. Projektów Czystszej Produkcji. Jednym z głównych aspektów „Czystszej Produkcji” jest zmniejszenie obciążenia środowiska i tzw. „dodatkowego efektu ekonomicznego”. Oznacza to, że projekty związane z koncepcją CP przynoszą korzyści zarówno środowisku, jak i organizacji. Strategia Czystszej Produkcji, która stała się podstawą systemu zarządzania środowiskowego, pozwala jednostkom organizacyjnym różnych organizacji podejmować dobrowolne zobowiązania środowiskowe nastawione na dobro środowiska. Istotną cechą Systemu Zarządzania Ekologicznego wg Czystszej Produkcji jest wykorzystanie istniejących baz danych dotyczących wpływu na środowisko oraz wymaganych prawem uwalniania do środowiska. To znacznie ułatwia każdej organizacji podejmowanie dobrowolnych decyzji o wdrożeniu takiego systemu. Celem niniejszej pracy jest charakterystyka strategii Czystszej Produkcji i próba oceny jej roli w procesie realizacji idei zrównoważonego rozwoju, na przykładzie firmy produkcyjnej. Korzyści wynikające ze strategii w postaci wymiernego efektu ekonomicznego, zmniejszonego zużycia energii elektrycznej, ciepła i wody są oczywiste. Ponadto, nastąpił spadek zanieczyszczeń poprzez emisję gazów, pyłów i produktów odpadowych.
Cleaner Production is a kind of environmentally friendly enterprise management strategy. It is addressed not only to entrepreneurs but also to local government units. Its application facilitates the management of an organization focusedon sustainable development. Organizations that decide to voluntarily implement the CP strategy constantly strive to reduce pollution, energy consumption and costs related to environmental fees, through the development and implementation of so-called Cleaner Production Projects. One of the main aspects of “Cleaner Production” is the reduction of the environmental burden and the so-called “additional economic effect”. This means that projects related to the CP concept benefit both the environment and the organization. The Cleaner Production strategy, which has become the basis of the environmental management system, allows organizational units of various organizations to make voluntary environmental commitments focused on the good of the environment. An important feature of the Cleaner Production Environmental Management System is the use of existing databases of environmental impacts and legally required releases to the environment. This makes it much easier for each organization to make voluntary decisions about implementing such a system. The aim of this work was to show what the Cleaner Production strategy consists in and its role in pursuing the idea of sustainable development, on the example of a manufacturing company. Benefits resulting from the strategy in the form of a measurable economic effect, reduced consumption of electricity, heat and water are obvious. In addition, there was a decrease in pollution through the emission of gases, dust and waste products.

Opis:
This paper presents frustum cone drawpiece analysis made of titanium CP2 sheet by a single incremental sheet forming. Central composite design has been adopted to carry out an experiment containing 20 runs, then multi-criteria parameter optimization has been done. Optimal parameters have been validated and responses deviations do not exceed 4% compared to created models. For the drawpiece formed with optimal parameters, AGRUS optical measurement and X-ray tomography has been applied to check the obtained of the part wall thickness and general deviations compared to the CAD model. The wall angle discrepancy of the cone generatrix has also been analyzed. No gaps or ruptures have been confirmed by X-ray. The blank rolling direction has a significant effect on the drawpiece deviations. The measurement results showed deviations of the drawpiece wall angle +0.27°/- 0.06°, sheet thickness on the cone +0.012/-0.04 mm and +0.151/-0.096 mm from the reference CAD geometry.
W pracy przedstawiono analizę wytłoczek w kształcie stożka ściętego wykonanego z blachy tytanowej CP2 metodą jednopunktowego przyrostowego kształtowania. Do przeprowadzenia eksperymentu obejmującego 20 przebiegów przyjęto centralny plan kompozycyjny, następnie dokonano wielokryterialnej optymalizacji parametrów. Dokonano walidacji optymalnych parametrów, a uzyskane wyniki nie przekraczają 4% w odniesieniu do stworzonych modeli. Dla wytłoczki uformowanej z optymalnymi parametrami zastosowano pomiar optyczny AGRUS oraz tomografię rentgenowską w celu sprawdzenia uzyskanej grubości ścianki wytłoczki i odchyłek w porównaniu z modelem CAD. Przeanalizowano również rozbieżność kątów ścian tworzących stożka. Za pomocą skanu rentgenowskiego potwierdzono brak szczelin i pęknięć wytłoczki. Kierunek walcowania półfabrykatu ma istotny wpływ na odchyłki. Wyniki pomiarów wykazały odchylenia kąta ścianki wytłoczki +0,27/-0,06°, grubości ścianki na stożku +0.012/-0.04 mm oraz +0.151/-0.096 mm od geometrii referencyjnej CAD.

Opis:
In this material production research, undoped and Ba-doped nanostructured PbS films are fabricated on glass surfaces by SILAR method. The structural, optical and morphological properties of the films are examined via scanning electron microscopy, UV-vis spectrophotometry and X-ray diffraction analysis. Scanning electron microscopy analysis revealed that Ba-doping concentration influences the size of the thin film's nanoparticles. X-ray diffraction results showed that all of the thin films are in a face centered cubic structure. Optical studies, in the room temperature, revealed that the optical band gap of the films increases as Ba-doping concentration is increased. The intercept values on the energy axis in the range of 1.86 eV and 2.12 eV for 1% and 8% Ba-doped PbS films respectively. As a result, it is concluded that the structural, optical and morphological properties of the fabricated thin films are directly depend on the Ba doping ratio.

Opis:
In the modern World, Catholic Church is presented by two different legal institutions i.e. The Catholic University and The Ecclesiastical University. Author of the article describes the beginning and development of the University, which was catholic and ecclesiastical on the beginning of its existence. Actually, these two independent legal institutions have common elements, which appeared from the nature of the university itself. Therefore, the conception of the University was expressed in Charta Magna of the European Universities and then referred to Catholic and Ecclesiastical Universities. Also, the differences between these two types of Universities were presented at the end of the article.

Opis:
Tak liturgia, jak też pobożność ludowa związane są nierozłącznie z wielością obrzędów, zwyczajów i wierzeń. Są one specyficznym wyrazem religijności i wiary, pielęgnowanym często przez całe lata. Obok wymiaru religijnego stanowią one ważny przejaw kultury danego narodu czy konkretnej społeczności. Obserwowany zanik zwyczajów i obrzędów religijnych wymusza niejako konieczność ich zbadania i utrwalenia. Ks. prof. Jerzy Kopeć CP jest przykładem naukowca, dla którego ta właśnie problematyka stała się jednym z wielu tematów badań naukowych. Badania te wymagały specyficznej metody naukowej oraz źródeł. W tym przypadku praca polegała na przeprowadzeniu badań ankietowych jak też dotarciu do oryginalnych tekstów związanych z daną obrzędowością. Oryginalną metodę opracowaną przez ks. Profesora Kopcia widzieć trzeba także w kontekście jego pracy promotorskiej przy powstawaniu kolejnych rozpraw naukowych. Przedstawienie osoby księdza Profesora Kopcia, jak też problemu badań nad obrzędowością winno przyczynić się do podjęcia na nowo badań zapoczątkowanych przez niego.
Both liturgy and popular piety are inseparably related with a variety of rituals, customs and beliefs. They constitute a specific manifestation of devotion and faith, often nurtured over many years. Apart from their religious character, they also make important part of national or community cultures. The gradual disappearance of customs and religious rituals evokes a necessity to research them and to preserve knowledge about them. Rev. Prof. Jerzy Kopeć CP is among the researchers who undertook studies in that domain, among his many scientific interests. His research tool was a questionnaire. He also consulted original texts related to particular types of customs and rituals. The original research methodology developed by Rev. Prof. Kopeć must also be looked at from the perspective of his being a supervisor of numerous research works of his students. The results of Rev. Prof. Kopeć’s research on customs and rituals can be inspirational to researchers wishing to continue the work he began.

Opis:
A series of $Fe_{3-x}Ti_xSn$ disordered alloys (where x = 0, 0.25, 0.5, and 0.75) obtained by arc-melting were studied. Directly after the melting all samples were mechanically crashed and in that form examined by the X-ray diffraction and Mössbauer effect methods. In $Fe_{3-x}Ti_xSn$ alloy with x = 0 three phases exist: FeSn (B35), $FeSn_2$ (C16) and Fe(Sn) (A2). The contributions of these phases decrease very fast in aid of ternary Fe-Ti-Sn alloys with the B2 and $D0_3$/$L2_1$ types of structure, as Ti atoms concentration increases. It was shown that these ternary alloys consist of four distinct Fe-Ti-Sn phases with contributions depending on the value of the x parameter. The value of hyperfine magnetic field $(B_{hf})$ parameter at the Fe nuclei is equal to about 110 kG for FeSn and $FeSn_2$ phases. However in alloys with A2, B2 and $D0_3$/$L2_1$ type of structure this value changes from 0 kG to 335 kG and can be considered (in the first approximation) as a function of Fe atoms number in the nearest neighborhood.

Opis:
Zr-Cu-Ni-Al bulk metallic glass is an attractive alloy system for scientific research and engineering applications. Alloys from this system exhibit high strength, hardness, corrosion resistance and good glass forming ability which makes them useful in many applications. In order to successfully apply amorphous materials, it is necessary to characterize their structure and properties, which are mutually dependent. The mechanical properties of the Zr-based amorphous alloy are the result of its unique, disordered structure. In this experiment, amorphous alloy of desirable composition in the form of a plate with thickness of 2 mm was prepared by melting high purity Zr, Cu, Ni, Al elements and casting into a copper mould by applying an ejection pressure. The amorphousness of rapidly solidified Zr₅₅Cu₃₀Ni₅Al₁₀ plate was examined by X-ray diffraction and microscopic observation. These investigations revealed that the studied Zr-based sample was amorphous. Based on experimental X-ray data the pair distribution function was calculated and discussion on possible atoms arrangement was carried out.

The law of growth of nitrided layers produced by gaseous nitriding of 31CrMoV9 alloy steel at different process parameters is described. 31CrMoV9 steel specimens were subjected to nitriding process in ammonia gas at three different temperatures: 510, 550 and 590°C, and for each temperature four different nitriding times were used. This way twelve specimens were produced. Nitrided specimens were investigated with optical microscopy, electron probe micro-analysis and x-ray diffraction. The nitrogen depth concentration profiles, deduced from electron probe micro-analysis, in conjunction with results of optical microscopy, were used to determine the thickness of the nitrided layers, i.e. the diffusion depth of nitrogen. From the dependence of the nitrided layer thickness on process parameters (temperature and time) it was possible to deduce the law that governs the growth of the nitrided layer for 31CrMoV9 alloy steel. Through this law, then, it is possible to predetermine the layer thickness for every real process parameter in nitriding of 31CrMoV9 steel, which is very important for technological applications.

Opis:
Glass-ceramic materials were developed from gabbro including MgO and $Al_2O_3$ additives. Heat treatments for phase transformation from glassy matrix to glass-ceramic were carried out at 1000C for 3 h. X-ray diffraction studies conducted on the glass-ceramic samples revealed that the phases formed in the glass-ceramics were cordierite, anorthite, diopsitic augite, forsterite and andesine. Glass and glass-ceramic materials were tested for wear properties against a harder alumina counterface using by a ball-on-disc tribometer at dry sliding condition. Wear tests were realized under the loads of 2.5, 5, and 7.5 N and at the sliding speeds of 0.1, 0.2, and 0.3 m/s. Wear rate of the glass and glass-ceramics ranged from 7.324 × $10^{-7}$ and 2.150 × $10^{-3}$-9.971 × $10^{-7}$ and 4.982 × $10^{-5} mm^3$/m, respectively. It was shown that the crystallization treatment caused the decrease of wear rate.

Opis:
The effect of ethylene partial pressure and temperature on the hydrocarbon decomposition rate was studied. As a catalyst, a triply promoted iron catalyst (with addition of small amounts of potassium, calcium and alumina oxides) was used. The mean crystallites size was ca. 17 nm. The processes were performed using pure ethylene or ethylene-nitrogen mixture under atmospheric pressure at the temperature range from 400 to 460°C. The growth of carbon mass as a function of reaction time was measured using a thermobalance. The phase composition of the samples after ethylene decomposition was determined using X-ray diffraction technique. The reaction rate was independent of ethylene partial pressure in the range from 0.25 to 1 bar. The maximal carbon yield for given experimental conditions was estimated.

Opis:
Bogata spuścizna naukowa ks. prof. Jerzego Kopcia ukazuje liturgię jako rzeczywistość wielowymiarową i wieloaspektową. Pośród wielu problemów badawczych, podejmowanych przez tego wybitnego liturgistę, jednym z głównych był problem kultu pasyjnego i maryjnego w ujęciu historycznym. W tematyce pasyjnej w ujęciu ks. prof. Kopcia widać wyraźnie rozwój kultu od najstarszych jego przejawów, skoncentrowanych głównie na Krzyżu Chrystusa i zbawczej mocy Jego śmierci, przez podkreślenie grzeszności człowieka aż do historycznego zaznaczenia soterycznej roli krzyża i męki Chrystusa jako ocalenia od grzechu. Powiązanie przez Księdza Profesora tematyki teologicznej z konkretnymi formami kultu pozwala na szersze spojrzenie na aktualne przejawy czci pasyjnej. Podobnie spojrzeć należy na badania dotyczące czci Matki Boskiej. Opisane przez Księdza Profesora rozwijanie się kultu maryjnego łączy on z analizą jego genezy, znaczenia oraz relacji między doktryną Kościoła a tym, co dzisiaj nazywamy pobożnością ludową.
Rev. Prof. Jerzy Kopeć’s extensive research legacy exhibits liturgy as a multidimensional and multifaceted reality. Among the variety of research issues undertaken by the famous liturgist there was the one concerning the Passion and the Marian cult as seen from the historical per- from its earliest manifestations, first focusing primarily on Christ’s Cross and the salvific power of His death, then on the highlighting of the sinfulness of man, up to the moment where the historical marking of the soteriological role of Christ’s Cross and Passion as a way of redemption from sin became prominent. Rev. Prof. Kopeć made a link between theology and the particular forms of cult, which allowed a wider insight into the current manifestations of Passion devotion. A similar view can be held on his research of the Marian cult. Rev. Prof. Kopeć analysed the roots of the cult and their influence on its growth. He showed how this cult related to the doctrine of the Church and to the phenomenon of popular piety.

Opis:
In the present study, powders produced from the volcanic basalt rocks were coated on pre-coated AISI 1040 steel with Ni-5% Al bond coat by atmospheric plasma spray coating technique. The coated specimens were characterized by optical microscopy, scanning electron microscopy, metallography and X-ray diffraction. Bonding strength of coatings was evaluated in accordance with the ASTM C-633 method. Coated basalt material from the APS coating system was determined in the glassy amorphous state by X-ray diffraction analysis. The coated samples were heat-treated at 800C for 1-4 h for crystallization. The phases formed in the basalt base glass-ceramic coatings were augite, Fe-diopside, anorthite, and andesine which were detected by X-ray diffraction analysis. Basalt based glass-ceramic coatings include splat, porosity and un-melted particles which were the characteristic of plasma sprayed coatings. Experiment result showed that the crystallization time increase caused the decrease of the bond strengths of the coatings.

ZnO thin films were deposited on microscope glass substrates by ultrasonic spray pyrolysis technique. The effects of annealing under various temperatures on the optical and structural properties of ZnO thin films were analyzed. The as-deposited and annealed ZnO thin films were investigated by UV/VIS spectrophotometer and X-ray diffractometer. Some of the optical properties of the films such as transmittance, absorbance and band gap energy were investigated by UV/VIS spectrophotometer. The crystallinity levels of the films were investigated, the structural parameters such as diffraction angle, full-width at half maximum, lattice parameters, grain size and dislocation density were calculated and structural properties were analyzed. X-ray diffraction patterns indicated that the ZnO films had a polycrystalline hexagonal wurtzite structure.

Opis:
After a short general description of the chemical etching of semiconductors the mechanisms of defect-selective etching are described in detail. Two distinct mechanisms that lead to the formation of etch pits and etch hillocks on dislocations emerging at a semiconductor surface are discussed. The principles of the formation of defect-related etch features are described for the HF-CrO$\text{}_{3}$-H$\text{}_{2}$O etching system used for etching of GaAs. A model of surface reactions is presented and the influence of illumination during etching on the defect-selectivity is emphasized. The use of ultra sensitive photoetching to study the nature and origin of complex defects in SI and n-like GaAs is documented. In particular, the concept for the formation of dislocation cell structure in undoped GaAs is presented and the ability of photoetching to reveal the structural changes during annealing is visualized.

Opis:
The aim of this research was to fabricate zinc oxide/cuprous(I) oxide-based heterojunction solar cells with the use of electrodeposition methods, and further to investigate their structures and photovoltaic properties. The ZnO and Cu₂O were used as n- and p-type semiconductors, respectively, to fabricate photovoltaic devices based on Ag/ZnO/Cu₂O/Cu(100) heterojunction structures. The crystallite sizes of ZnO and Cu₂O were determined to be 25.4(3) nm and 69.8(6) nm, respectively. It was pointed out that efficiencies of the solar cells can be gradually adjusted, using different thicknesses of Cu₂O layers, to achieve values as high as 2.7%. The standard diode model and high device performance provide new insights into the issue, outlining guidelines for high-performance solar cells and suggesting that a metal-n-type semiconductor-p-type semiconductor nanostructure-crystal layered, sandwiched-type architecture is a promising platform: to boost the efficiency.

Opis:
Al-Ti intermetallic compounds were coated by electro-spark deposition. Commercially pure titanium (Cp-Ti) (grade 2) and aluminum rods were used as substrate and electrode materials, respectively. During the electro-spark deposition experiments the following pulse parameters in a group were used: pulse current amplitude, pulse duration and pause between the pulses of a pulse group with 100-300-500 A, 50-100 μs, and 100 μs, respectively. Al-Ti coatings having a thickness range of 15-30 μm were formed on the surface of titanium substrate using electro-spark deposition process. The coating properties such as the roughness and the thickness increased with increasing pulse duration and pulse current amplitude. The mass transfer coefficient decreased with increasing pulse current amplitude and pulse duration. The quality of the adhesion characters of the coatings, determined by Rockwell-C adhesion test, becomes worse from HF-2 to HF-4, due to increase of pulse current amplitude. Depending on the electro-spark deposition process parameters, the coating formed as AlTi or as layered structure consisting of AlTi+$AlTi_3$ when pulse current amplitude increases. The Al-Ti coatings include some micro cracks lying throughout the coating from surface to interface which is nature of this process. The maximum cross-sectional hardness of the coatings were in the range of 800-1150 HV.

Opis:
Cuprous (I) oxide (Cu₂O)-based solar cells were fabricated with the use of the electrodeposition technique at nanometre-scale, and the structural, morphological and electrical properties were investigated. The Cu₂O layers were electrodeposited on crystalline and polycrystalline copper substrates. To complete the Cu₂O/Cu(100) and Cu₂O/Cu interfaces as the solar cells the top electrodes of silver paste were painted on the rear of Cu₂O. The microscopic analysis exhibits uneven surface morphologies of a Cu₂O film with the roughness of 92.5 nm, while the X-ray diffraction analysis reveals that the layers are Cu₂O-type polycrystalline structures with the thickness of 493 nm and the crystallite size of 69.8(6) nm. The theoretical analysis of the current-voltage curve was provided to determine the values of electrical parameters of the most efficient solar cell of Ag/Cu₂O/Cu(100) and clearly indicate presence of two Schottky barriers at interfaces.

Opis:
Besides the crystal preparation, the first and crucial step in the process of protein structure determination is proper processing of the collected diffraction images, as they provide the experimental observations used throughout the entire process of structure solution and refinement. In the last two decades several computer programs have been developed. Among the most used and popular are: HKL2000, MOSFLM, d*TREK and XDS package. To find out the advantages and disadvantages of the data processing programs, several very different data sets, including diffraction data from DNA/RNA and protein crystals were tested. It has been found that all the major programs for processing and analysis of diffraction data give excellent and comparable results with good quality, medium resolution data sets, but their treatment of very high resolution or imperfect data differs in terms of indexing, spot integration, scaling and the treatment of errors. If the diffraction data are of good quality and the problem is relatively straightforward, the automated approach to data processing may be most appropriate. On the other hand, if one is trying to squeeze out as much information from the experimental data as possible, then only expert manual processing can be successful, regardless of the data quality.

This study aimed to evaluate the concentrations of α1-acid glycoprotein (AGP), haptoglobin (Hp), serum amyloid-A (SAA) and ceruloplasmin (Cp) in healthy and various diseased cats and establish reference intervals (RIs) for these acute phase proteins (APPs) in healthy cats. The animal material of the study consisted of 40 healthy cats and 152 cats with various diseases. The serum APPs in the diseased group were higher than those in the healthy group, and age affected Cp concentration in healthy cats. Also, the systemic inflammatory response syndrome (SIRS) positive (+) group had significantly higher AGP concentrations than the SIRS negative (-) group. In conclusion, this study contributes to the limited number of studies on RIs in serum APPs concentrations in healthy cats. The results of this study suggest that APPs are valuable diagnostic tools for identifying the inflammatory processes of various diseases, and AGP concentration could help determine the severity of the inflammatory condition.

Opis:
Transparent zinc oxide thin films doped with molybdenum have been prepared using a DC reactive magnetron sputtering on glass substrates from metallic ZnMo target. The three films, called A, B, and C, had 1.9 at.% Mo, 2.8 at.% Mo and 4.7 at.% Mo, respectively. The composition of the films was determined by X-ray photoelectron spectroscopy. The analysis of Mo 3 $d_{5/2}$ core level spectra indicated that Mo exist in the films in $Mo^{6+}$ oxidation state irrespective of the Mo content in the film. The X-ray diffraction spectrum of film A showed a texture along the 002 orientation, while that of film B showed two peaks, one at $θ ≈ 34.5°$ and the other at $≈ 36.5°$ corresponding to 002 and 101 orientations, respectively. Film C showed two small peaks corresponding to 100 and 110 orientations. Optical measurements showed that all three films had a transmittance of about 80%. The energy band gap showed a linear increase as Mo concentration increases from 3.29 eV to 3.38 eV. The atomic force microscopy image of film A showed a homogeneous morphology of the surface of the film, while the atomic force microscopy images of films B and C showed an inhomogeneous one.

Opis:
Reducibility is a parameter which describes the ability of oxygen, combined with iron, to be removed from iron ore sinters by a reducing gas used in a blast furnace, and is often characterized by a Fe²⁺ content in a sinter. In sinters, iron at Fe²⁺ valence can occur in various types of minerals, which differ in values of reducibility. The set of sinters with the reducibility from 0.63%/min to 1.49%/min, prepared in the different laboratory conditions, were examined in terms of their mineral composition. The quantitative dependences between the fractions of the individual mineral constituents of the sinters and the values of reducibility were sought. The increase of the reducibility was correlated with a decrease of the content of magnetite and a rise of the fraction of hematite.

Opis:
Concurrent execution of work orders in the small and medium size enterprises (SME) imposes a necessity to consider many control problems concerning systems of repetitive concurrent manufacturing processes using common resources in mutual exclusion. In many cases a production system with a given structure of the processes resource requests can be seen as composed of subsystems with n cyclic processes sharing one resource. For given sets of possible values of the processes operation execution times a problem of finding schedules guaranteeing that no process waits for access to the common resources is considered. In particular for the assigned times of the operations execution a subproblem of finding all possible starting times of work orders execution for which waiting-free schedules exist has been formulated as a constraint programming (CP) problem. The starting times derived can be used as an alternative starting times of work orders execution in case of their possible delays. A state space of the problem’s solutions has been reduced using constraints based on the necessary and sufficient conditions for existence of a waiting-free n-process steady-state schedule. An illustrative example of Mozart-based software application to the solution of constraint logic programming problem considered has been presented.

Opis:
In the present paper the phase transformations occurring in hot worked and heat-treated Ni-rich NiTi shape memory alloy were studied using X-ray diffraction, differential scanning calorimetry and bend and free recovery measurements. Based on conducted measurements it can be seen that in the studied alloy two-step B2 ↔ R ↔ B19' phase transitions occurred. Due to the fact that during heating the phase transition B2 → R and R → B19' occurs in a very narrow temperature range and differential scanning calorimetry peaks overlap additional X-ray diffraction measurements were performed. Obtained characteristic temperatures from applied different experimental methods are in good agreement. The optimum heat-treatment was selected to obtain rods with a shape recovery temperature A_{f} below 37°C to prepare prototypes of medical implants activated by patients body heat.

Opis:
X-ray diffraction, scanning electron microscopy and hardness measurements were applied as experimental methods to investigate the structure and properties of the crystalline-amorphous Al-based composites prepared by mechanical alloying and subsequent high pressure high temperature compaction of the powders. It was possible to obtain bulk, fully dense crystalline-amorphous composites and the applied compaction technique allowed preservation of amorphous structure in the composite. Addition of amorphous $Al_{60}Nb_{40}$ phase to AA6061 alloy resulted in significant increase of hardness of the composite (120 HV), comparing to pure Al alloy compacted at the same conditions (75 HV).

Opis:
The effective soliton velocity in the presence of a periodic background differs from that when a soliton propagates alone. Using approximate relations for the Riemann-theta functions, the effective soliton velocity is derived and discussed. General relations are illustrated by examples of Korteweg de Vries and sine-Gordon equations because of the application in the Josephson junction theory.

Opis:
This paper presents the design aspects of low power digital PLL. The performance determining parameters of a digital PLL are lock range, capture range, jitter in generated output signal and power consumption. Its performance is mainly governed by two building blocks namely the voltage controlled oscillator (VCO) and phase detector. We have performed the complete analysis of phase noise and power consumption of current starved VCO, a novel D flip-flop based phase detector and transmission gate based charge pump. We have introduced a charge pump which is giving a remarkable reduction in reference spur. As PLL is used for many applications like as a frequency synthesizer, for clock deskewing, for jitter reduction, in FM radios so everyone demands a low cost low power highly integrated PLL design. Best efforts have been made to design a MOSFET based low power, low cost GHz range digital PLL. The main objective of this paper is to design a low power digital PLL which produces a very stable clock signal having jitter less than 1ps, power consumption less than 805uw ,output frequency ranged from 0 to380MHz at a supply voltage of 1.8V.

Opis:
Optical constants, dispersion and oscillator parameters of different thicknesses of amorphous $Ge_{25}Cd_5Se_{70}$ films have been deposited onto glass substrates using thermal evaporation technique. The optical constants have been investigated by optical spectrophotometry measurements. The straight forward analysis proposed by Swanepoel, which is based on the use of the extremes of the interference fringes has been used in order to derive the refractive index and the film thickness in μm range. The refractive index could be extrapolated by the Cauchy dispersion relationship over the whole spectral range, which extended from 400 to 2500 nm. It is observed that, refractive index n increases with the film thickness. The possible optical transition is found to be allowed indirect transition with energy gap increase from 1.915 to 1.975 eV with increasing film thickness. The dispersion of the refractive index is discussed in terms of the Wemple-DiDomenico single oscillator model. The interband oscillator wavelength, the average oscillator strength, and the optical conductivity were estimated for different thicknesses of amorphous $Ge_{25}Cd_5Se_{70}$ films.

Opis:
The “second generation” of glyphosate-tolerant soybean (GT2 soybean) was developed through a different technique of insertion of the glyphosate-insensitive EPSPs gene, in comparison with “first generation” of glyphosate-tolerant soybean. However, there is not enough information available about glyphosate selectivity in GT2 soybean and the effects on the quality of seeds produced. The aim of this study was to evaluate tolerance to glyphosate and seed quality of soybean cultivar NS 6700 IPRO (GT2) with cp4-EPSPs and cry1Ac genes, after application at post-emergence (V4). The experiment was conducted in a randomized block design with four replicates and seven treatments, or rates of glyphosate (0; 720; 1,440; 2,160; 2,880; 3,600; 4,320 g of acid equivalent − a.e. · ha−1). Assessments were performed for crop injury, SPAD index and variables related to agronomic performance and seed quality. A complementary trial with the same cultivar and treatments in a greenhouse was conducted in a completely randomized design with four replications. Data analysis indicated no significant effect of glyphosate on V4 on agronomic performance and physiological quality of seeds, for two growing seasons. The soybean cultivar NS 6700 IPRO (GT2), with cp4-EPSPs and cry1Ac genes, was tolerant to glyphosate up to the maximum rate applied (4,320 g a.e. · ha−1) at post-emergence (V4). The quality of soybean seeds was not affected by glyphosate up to the maximum rate applied (4,320 g a.e. · ha−1) at post-emergence (V4).

In the paper the crystal structure of single crystal CMSX-4 blade casts, applied in high pressure turbine of aircraft engines was analyzed. The longitudinal section of blade, cast at withdrawal rate of 3 mm/min was used as a sample. During the conducted research, following X-ray diffraction methods were applied: EFG Ω-scan, Auleytner X-ray topography and analysis of diffraction reflex profile ("rocking curve"). The authors determined crystal orientation in entire blade casts on the basis of set criterion concerning values of angle α - deviation of [001] direction from the direction of cast withdrawal. Conclusions concerning the crystal structure quality of the blade were drawn based on results from three different research methods. Local changes in crystal orientation on the surface of blade cast, also areas with significant structure defect degree and the presence of internal stresses were characterized.

Opis:
Spatially resolved X-ray diffraction is introduced and applied for micro-imaging of strain in GaAs and GaSb layers grown by epitaxial lateral overgrowth on GaAs substrates. We show that laterally overgrown parts of the layers (wings) are tilted towards the underlying mask. By spatially resolved X-ray diffraction mapping the direction of the tilt and distribution of tilt magnitude across the width of each layer can be readily determined. This allows measuring of the shape of the lattice planes in individual epitaxial stripes. In GaSb/GaAs heteroepitaxial laterally overgrown layers local mosaicity in the wing area was found. By spatially resolved X-ray diffraction the size of microblocks and their relative misorientation were analyzed. Finally, microscopic curvature of lattice planes confined between two neighboring slip bands in thermally strained Si wafers is measured. All these examples show advantages of spatially resolved X-ray diffraction over a standard X-ray diffraction when applied for analysis of crystalline microstructures.

Opis:
The growth-related microstructure and texture of the Co₂MnAl-type Heusler alloy in the form of a melt-spun ribbon was studied by electron microscopy, electron backscattered diffraction and X-ray diffraction. It is shown that melt spinning produces a single-phase disordered Heusler alloy. The fine grain structure at the wheel side of the ribbon exhibits no texture, while dominant columnar grain structure formed on the free surface side exhibits the ⟨111⟩ fibre texture with a declination by about 10 degrees in the spinning direction. The dendritic growth of columnar crystals causes inhomogeneity of the chemical composition on a micrometre scale with a higher Co and Al concentration in the centre of dendritic arms and a higher concentration of Mn at the dendrite arm boundaries.

Opis:
Fe-based amorphous alloys were characterized by X-ray diffraction, transmission Mössbauer spectroscopy and vibrating sample magnetometry. The studies were performed on (Fe_{0.75}B_{0.15}Si_{0.1})_{100-x}Zr_{x} (x=0, 1, 3) metallic glasses in the form of ribbons. The glassy samples were prepared by the "melt spinning" technique in argon protective atmosphere. The XRD patterns show the broad diffraction halo that is typical for amorphous Fe-based alloys. The Mössbauer spectroscopy allows to study the local environments of the Fe atoms in the glassy state, showing the changes in the amorphous structure due to the changing of Zr addition. From hysteresis loops obtained from vibrating sample magnetometry measurements, coercive force and saturation magnetization were determined versus different Zr content. The obtained magnetic properties allow to classify the studied amorphous alloys in as-cast state as soft magnetic materials.

Opis:
The effect of particle size on the magnetic and optical properties of cobalt oxide $Co_3O_4$ has been investigated. Single phase $Co_3O_4$ nanoparticles were synthesized by co-precipitation route and their structure was confirmed through X-ray diffraction analysis. The average crystallite sizes of the nanoparticles as determined from the X-ray diffraction were found to lie in the range of 13 to 59 nm. At room temperature these particles show paramagnetic response and the DC magnetic moment of the samples showed an increasing trend with increasing particle size. Both the antiferromagnetic Néel temperature $T_{N}$ and the low temperature moment depict finite size effects in the AC susceptibility measurements. The optical absorption studies show that there are two direct band gaps in $Co_3O_4$, the main energy band gap and a sub-band located inside the main energy gap. The values of these energy band gaps for the 45 nm particles were determined to be 3.15 and 1.76 eV, respectively. The direct band gap in these particles clearly shows a blue shift with decreasing size attributable to the quantum confinement effect.

The crystalline structure and morphology of obtained films were characterized by X-ray diffraction, scanning electronic microscope and energy dispersive X-ray analysis methods. The films were polycrystalline and showed preferred orientation. The surface morphology of these films looked relatively smooth and homogeneous in the scanning electron microscope image. The energy dispersive X-ray analysis spectra showed that the expected elements exist in the thin films.

Opis:
X-ray rocking curve imaging technique was used to study crystallographic perfection of laterally overgrown epitaxial structures. We focus on rocking curve imaging studies of Si-doped GaAs and GaSb laterally overgrown layers grown by liquid phase epitaxy on $SiO_{2}$ masked GaAs and GaSb/GaAs substrates, respectively. High spatial resolution offered by rocking curve imaging technique allows studying the effect of laterally overgrown epitaxial wing tilt towards the mask. Distribution of tilt magnitude over the area of laterally overgrown epitaxial stripes is easily determined. In heteroepitaxial GaSb/GaAs laterally overgrown epitaxial structures local mosaicity in the wing area was detected. Since individual grains are clearly visible on rocking curve imaging maps, their size and relative misorientation can be determined.

Opis:
The article presents a numerical analysis of the CP745 marine propeller model by means of the improved vortex method and CFD simulations. Both numerical approaches are validated experimentally by comparing with open water characteristics of the propeller. The introduced modification of the vortex method couples the lifting surface approach for the propeller blades and the boundary element method for the hub. What is more, a simple algorithm for determination of the propeller induced advance angles is established. The proposed modifications provide better results than the original version of the vortex method. The accuracy of the improved method becomes comparable to CFD predictions, being at the same time a few hundred times faster than CFD.

Opis:
The structure of an F-AlCoPdGe alloy was determined by single-crystal X-ray diffraction analysis: space group Pa3̅ (No. 205), Pearson symbol cP1128-142.4, a = 24.4338(4) Å; R1 = 0.0526 for the observed 5106 reflections with $F_0$ > 4.0σ$(F_0)$. The F-AlCoPdGe alloy exhibited three types of pseudo-Mackay clusters (pMCs). The first shell of the Co(13)-pMC at 24d indicated a coordination polyhedron typically found in Al-Co binary approximants; the second shell was a combination of an M icosahedron and an Al icosidodecahedron, where M is a mixed site of Pd and/or Co. The first shell of the Co(14)-pMC at 4b consisted of 20 partially occupied Al positions arranged in a dodecahedral fashion; its second shell was also composed of an M icosahedron and an Al icosidodecahedron. The first shell of the Al(18)-pMC at 4a consisted of a combination of an M cube and an Al octahedron, resulting in the rhombic dodecahedral arrangement; its outer shell structure was similar to those of the other pMCs. The structure of the F-AlCoPdGe phase comprised an arrangement of these three types of pMCs together with interstitially placed Al icosahedra around the Pd/Al(1) and Pd/Al(2) sites.

Opis:
Several techniques were used to investigate the chemical and phase composition of four trial batches of nitinol powder produced by calciothermic reduction as well as their morphology and granulometric composition. Almost all powders produced by a similar procedure contained an allowable amount of impurities and were practically free of minor detrimental phases such as Ti₂Ni and Ni₃Ti. The powders under study have gamma or lognormal particle size distributions and spongy particles morphology typical of this production method. The tap density over 3g/cm³ was achieved at least in one case, which gives us an opportunity to successfully produce bulk articles by subsequent treatments such as sintering or hot isostatic pressing.

Opis:
We have prepared $Co_{x}Cu_{1-x}$ granular alloys with Co contents (x ≈ 0.01-0.30) by chemical reduction. Samples are characterized by X-ray diffraction and transmission electron microscopy yielding particles of mean diameter 8-20 nm formed in fcc phase. The branching in ZFC/FC magnetization behavior confirm superparamagnetism in the samples, characterized by blocking temperature distributions which represent variations in particle size and inhomogeneities of their chemical compositions. Magnetic field dependence of magnetization show hysteresis loops, and the magnetization at any temperature 4-300 K is a combination of ferromagnetism and superparamagnetism. The saturation moment of Co for the ferromagnetism part increases with the Co content. But the coercive fields $(H_{C})$ and magnetic anisotropy of the particles do not vary with Co concentration. Annealed samples exhibit exchange bias in the range 20-150 Oe at 4 K. The results indicate formation of nanoparticles of CoCu alloy in a core-shell type structure with Co being concentrated near the core.

Opis:
Magnesium and its alloys are interesting materials for biodegradable implant applications. Magnesium alloys have very good strength properties, they are lightweight, but their main disadvantage is a low corrosion resistance in the physiological environment. Various modifications of a Mg alloys surface by deposition of different coatings are used to prevent untimely dissolution. The article presents the investigation results of a thin ZnO coating deposited on a MgCa2Zn1Gd3 alloy by means of the magnetron sputtering method. The studies include: scanning electron microscope observation of the ZnO surface, X-ray phase analysis, surface roughness measurement in atomic force microscopy, the microhardness test and potentiodynamic corrosion resistance test in the Ringer solution at 37°C. It was found that the ZnO coating is compact and continuous. It increases the hardness of the MgCa2Zn1Gd3 alloy and also improves its corrosion resistance. The corrosion potential is shifted slightly towards the positive values from -1.52 V to -1.50 V for the alloy with the ZnO coating.
