Opis:
One of the main reasons to study more about the dynamics of solar radio bursts is because solar these bursts can interfere with the Global Positioning System (GPS) and communications systems. More importantly, these bursts are a key to understand the space weather condition. Recent work on the interpretation of the low frequency region of a main solar burst is discussed. Continuum radio bursts are often related to the solar activities such as an indication of the formation of sunspot, impulsive phase of solar flares and Coronal Mass Ejections (CMEs) and their frequencies correspond to the densities supposed to exist in the primary energy release volume. Specifically, solar burst in low frequency play an important role in interpretation of Sun activities. In this work, we have selected few solar bursts that successfully detected by our station at the National Space Centre, Banting Selangor. Our objective is to correlate the solar burst with Sun activities by looking at the main sources that responsibility with the trigger of solar burst. It is found that type II burst is dominant with Coronal Mass Ejections (CMEs), type III burst associated with solar flare, IV burst with the formation of active region and type U burst high solar flare. We believed that this work is a good start to monitor Sun’s activities in Malaysia as equatorial country.

Opis:
The work three ceramic compositions based on PbZr0.49 Ti0.51O3 doped with manganese (Mn), antimony (Sb), lanthanum (La) and tungsten (W) were obtained. The introduction of a set of admixtures was aimed at improving the sinterability of ceramic materials and optimizing its electrophysical parameters. Multi-component materials of the PZT-type with a general formula: Pb(PbZr0.49 Ti0.51)0.94 Mn0.021 Sb0.016 LayWz O3 (where y from 0.008 to 0.012 and z from 0.012 to 0.014) were prepared by the conventional mixed oxide method. After mixing and drying the powder mixtures were calcined in air at 850°C for 4 h, while densification of the powders was carried out by the free sintering method at 1150°C for 2 h. The final steps of technology were grinding, polishing, annealing and putting silver paste electrodes onto both surfaces of the samples for electrical testing. XRD, SEM, EDS, dielectric, ferroelectric, piezoelectric properties and DC electrical conductivity of the obtained ceramic compositions were carried out. X-ray tests of the crystal structure conducted at room temperature have shown that all obtained the PZT-type materials were a single phase (perovskite type) without the presence of a foreign phase. Symmetry of the crystal lattice was identified as space group P4mm. Temperature dielectric studies have shown high values of dielectric permittivity and low dielectric loss. The presented physical properties of ceramic samples based on PZT confirm their predisposition for application in modern microelectronic and micromechatronic applications.

We get a Ritt type improvement, i.e. from 0 to sectors of the Riemann surface of the function log for spaces of ultraholomorphic functions, by first establishing a generalization to some nonclassical ultradifferentiable function spaces.

Opis:
The paper presents the results of thermodynamic analysis of precipitation process of MX-type interstitial phases in austenite. The subject of the investigation were two newly developed high strength low alloy microalloyed steels with similar concentration of C and N and with diversified amount of Nb, Ti and V microadditions. Thermodynamic analysis of the state of phase equilibrium of structural constituents, taking into consideration the austenite of investigated microalloyed steels, was mainly focused on analytic calculations of chemical composition of austenite and the content and chemical composition of potential MX-type interstitial phases (M – metal, X – metalloid) as a function of heating or cooling temperature. The analysis of precipitation process of complex carbonitrides in austenite under thermodynamic equilibrium conditions has allowed to define stoichiometric compositions of carbonitrides as a function of temperature along with determination of their volume portion. This study was based on the model proposed by Hillert and Staffanson, which was subsequently developed by Adrian. The results of performed investigation can be used to develop the appropriate parameters of thermomechanical treatment of metallurgical products from the tested HSLA-type steels.

Opis:
The main purpose of the article is the analysis of the relations between thermic weather types in Hel and types of circulation from Osuchowska-Klein’s classification (1978). Thermic types have been constructed on the basis of A. Woś’s classification of weather types (1993). As a result, in the study eleven thermic types have been distinguished and grouped into three categories of weather: warm, transitory and frosty. Detailed analysis has revealed that the frequency of thermic weather types in particular types of circulation is determined by the character of circulation (cyclonic/anticyclonic) as well as by its direction. The most numerous types of circulation over Poland: E (north-eastern anticyclonic) and CB (north-western cyclonic) most often are accompanied by warm and transitory weather. In Hel the warm weather group is conditioned mainly by the circulation types associated with the advection of the air from the West or South; transitory and frosty groups are related to the types of circulation conditioning the airflow from the northern or eastern sector.
Zasadniczym celem pracy było określenie częstości występowania w Helu termicznych typów pogody (w latach 1976-1995), w zależności od typu cyrkulacji atmosferycznej (według klasyfikacji B. Osuchowskiej-Klein 1978). Termiczne typy pogody wyróżniono na podstawie klasyfikacji zaproponowanej przez A.Wosia (1993), opartej na dobowych warunkach pogodowych. W niniejszym opracowaniu jedynym kryterium grupowania pogody w klasy były charakterystyki termiczne z tej klasyfikacji. Biorąc pod uwagę dobowe wartości temperatur ekstremalnych (tmax, tmin), wyróżniono trzy podstawowe grupy pogód: ciepłe, przejściowe oraz mroźne, które w zależności od wartości średniej dobowej temperatury powietrza podzielono na 11 termicznych typów pogody. W opracowaniu, w pierwszej kolejności określono typy decydujące o charakterze cyrkulacji nad obszarem Polski, a następnie przeanalizowano towarzyszące im termiczne typy pogody w półroczu chłodnym (X-III), ciepłym (IV-IX) oraz w skali roku. Uzyskane wyniki pozwalają na wysnucie następujących wniosków. Cyrkulacja atmosferyczna w dużej mierze determinuje częstość występowania termicznych typów pogody w Helu, przy czym rola kierunku adwekcji mas powietrza jest większa niż charakter (cyklonalny/antycyklonalny) układu barycznego. Występowaniu pogód ciepłych sprzyja większa frekwencja typów cyrkulacji charakteryzujących się napływem powietrza z sektora południowego i zachodniego. Pogody przejściowe i mroźne towarzyszą najczęściej typom cyrkulacji sprowadzającym do Polski powietrze z północy lub ze wschodu. Najliczniej reprezentowanym typem pogody jest pogoda umiarkowanie ciepła, która pojawia się najczęściej późną wiosną i jesienią (z maksimum w październiku) przy najmniejszej częstości w lutym. Do grupy typów o dużej frekwencji należy ponadto: pogoda bardzo ciepła – notowana wyłącznie od kwietnia do października oraz pogoda chłodna – występująca od października do maja. W półroczu chłodnym występuje większe zróżnicowanie termicznych typów pogody w zależności od typu cyrkulacji atmosferycznej.

The paper deals with the role of multilingualism in selected text types. The reflections on forms of multilingualism and occasions for using multiple languages in a text lead to the creation of a typologythat distinguishes between obligatory and optional use of multiple languages in text types. The obligatory multilingualism is constitutive in dictionaries, textbooks and teaching materials. Optional multilingualism, which was examined using the example of German advertising texts and grave inscriptions from Germany and Denmark, reinforces the main function of the text.

Opis:
Fuzzy logic systems, unlike black-box models, are known as transparent artificial intelligence systems that have explainable rules of reasoning. Type 2 fuzzy systems extend the field of application to tasks that require the introduction of uncertainty in the rules, e.g. for handling corrupted data. Most practical implementations use interval type-2 sets and process interval membership grades. The key role in the design of type-2 interval fuzzy logic systems is played by the type-2 inference defuzzification method. In type-2 systems this generally takes place in two steps: type-reduction first, then standard defuzzification. The only precise type-reduction method is the iterative method known as Karnik-Mendel (KM) algorithm with its enhancement modifications. The known non-iterative methods deliver only an approximation of the boundaries of a type-reduced set and, in special cases, they diminish the profits that result from the use of type-2 fuzzy logic systems. In this paper, we propose a novel type-reduction method based on a smooth approximation of maximum/minimum, and we call this method a smooth type-reduction. Replacing the iterative KM algorithm by the smooth type-reduction, we obtain a structure of an adaptive interval type-2 fuzzy logic which is non-iterative and as close to an approximation of the KM algorithm as we like.

Opis:
Pampa cytoplasm has served as the main source of male sterility in hybrid rye breeding programs in Europe for 30 years and there is a need of introducing new CMS sources to prevent cytoplasm uniformity. Several CMS sources were discovered and studied in the former Soviet Union. The CMS sources in rye can be classified into two major groups, the P (Pampa) type and the V (Vavilov) type. The main goal of this study was to widen the “sterile” cytoplasm as a tool for rye hybrid development. ‘Koerntner’ represent the same or similar source of male sterility like CMS ‘CM’ and CMS ‘V type’. This source is genetically different from the sources of male sterility ‘Pampa’ and ‘D. Zlote’-1. In F2 progenies develop by self-pollination F1 plants, of P.6.2-1 × line 113, segregation according to the ratio three male fertile plants to one male sterile, was observed. The segregation ratio in F2 indicate that one or two recessive gene(s) are being involved in the interaction with mutated (S) cytoplasm to cause male sterility.

Opis:
The formation of two different solar bursts, type III and V in one solar flare event is presented. Both bursts are found on 19th September 2011 associated with C-class flares on active region 1295. From the observation, we believed that the mechanism of evolution the bursts play an important role in the event. It is found that type V burst appeared in five minutes after type III. There are a few active regions on the solar disk but most are magnetically simple and have remained rather quiet. An interpretation of this new result depends critically on the number of sunspots and the role of active region 1295. Sunspot number is increased up to 144 with seven sunspots can be observed. During that event, the speed of solar wind exceeds 433.8 km/second with 2.0 g/cm3 density of protons in the solar corona. Currently, radio flux is also high up to 150 SFU. The solar flare type C6 is continuously being observed in the X-ray region for 24 hours since 1541 UT and a maximum C1 is detected on 1847 UT. Although the sources of both bursts are same, the direction and ejection explode differ.

These two types of portals have the same main geometric measurements. They differ only at the medium level in the horizontal plane. The first type of the portal on the middle level has an H-frame, while the second type has an X-frame. In this paper, dynamic parameters of the two portals have been compared. Estimation has been done to find which of the two types of portals has more favourable dynamic stability for overturn.

The article is devoted to research into the systematization of the structural and semantic types of partially phraseologized sentences. Partially phraseologized sentences have been ascertained to have their functional and communicative purpose in language and speech. The formal and semantic principles of the typology of partially phraseologized sentences have been determined. Structural typologies of partially phraseologized sentences are based on quantitative and morphological criteria. Analyzed have been the structural types of partly phraseologized sentences. Partially phraseologized sentences are formed by two‑, three‑, four‑, and five‑part phrase‑complexes. The semantic types of partially phraseologized sentences are based on the type of syntactic relations between their two parts, depending on which we can single out: 1) sentences with temporal relations; 2) sentences with relations of generalized condition; 3) sentences with explanatory relations; 4) sentences with applicative relations.

This work1 presents results on the integration of frame-based representations into the framework of eXtensible MetaGrammar (XMG). Originally XMG allowed for the description of tree-based syntactic structures and underspecified representations of predicate-logical formulae, but the representation of frames as a sort of typed feature structure, particularly type unification, was not supported. Therefore, we introduce an extension that is capable of handling frame representations directly by means of a novel -dimension. The aim is not only to make possible a straightforward specification of frame descriptions, but also to offer various ways to specify constraints on types, be it as a connected type hierarchy or a loose set of feature structure constraints. The presented extensions to XMG are fully operational in a new prototype.

Opis:
Main genes determining white coat colour in Arctic foxes are: recessive gene d and incompletely dominant, autosomal gene S with lethal effect in homozygous condition. The white coat colour of Arctic foxes bred on Polish farms had been determined solely by the recessive gene until the 1970s, when the Shadow variety was imported from Norway. The genetic code of the two varieties was different, but this fact was not taken into account. The results obtained in the present study do not confirm the theories on the heredity of white coat colour of Arctic foxes. The authors of these theories assumed that the coat colour depends on the presence of a recessive gene, the only factor responsible for the white furcoat. Apart from Polar and Shadow white foxes, there is a wide variety of darker white animals, and this fact suggests that there is a number of cumulative genes responsible for the intensity of coat pigmentation.

Opis:
The present article is an attempt to analyze the solar burst Type II observations based on solar flare and Coronal Mass Ejections (CMEs) events. We choose an intriguing type II radio burst with a velocity of 1193 kms-1 that occurred on 2012 November 13 at 2:04:20 UT. In this case, the study of solar radio burst type III is of paramount importance because of the fact that it helps to gain an insight of generation mechanisms of solar flare and Coronal Mass Ejections (CMEs) phenomena. Here, we have got a reasonably clear idea of the various forms under which the type III continuum emission may appear and potentially form a type II burst. However, in this case, the Type II solar burst only successfully forms a fundamental structure within the first few minute period, but broken suddenly before evolve a harmonic structure. This phenomenon is very interesting to be tackled and study. How the burst suddenly broken is still ongoing research seems the event is very rare and hard to be proved. There are a few questions that cause this unique situation which related to: (i) the intensity and duration of type III burst which also related to the classification of solar flare (ii) the probabilities CMEs to occur during that time and also the factor of the total amount of massive burst that exploded, Thus, we can conclude that the solar burst type III event still tells us an enigmatic characteristic from time to time due to the relationship of energetic particles and streams of particles with coronal magnetic fields and the pattern of Sun activity due to the 24th solar cycle. It might an interesting to study in detail the main factor that caused the Type II solar burst broken. Indirectly, it might because of the very intense of solar flares that make the percentage of energy of solar flare become more dominant rather than the acceleration of particles through the Coronal Mass Ejections. Thus, we realize that the potential energy during this event is higher than the kinetic energy of the particles.

Opis:
A preliminary correlation study of the solar burst type III with a type Iv solar burst of has been made. On the basis of this study and in combination with the observation in radio emission, an interpretation of the mechanism of the occurrence of this event has been proposed. We have noted that an individual type III burst also can be observed at 13:54-13:58 UT from 500 MHz. Based on 3 days observation beginning from 31st March 2015, the solar activity is gradual increased. The highest solar flare can be observed is only a class of M8 flare. There was a CMEs event that directed to the Earth is detected. From the selected event, although theoretically solar radio burst type III is alternating with type IV solar burst. This huge explosion generated the M-class flare which can affect the Earth and satellites. The solar wind velocity recorded is 384.2 km/second while the density of protons is 3.6 protons/cm3. The total magnetic field during this event also quite big which is 4.6nT. The alternating of solar burst type III and IV would probably depends on the tendencies to form the CMEs event. The morphology of thermal and non-thermal flare plasma is of particular significance because it holds many important signatures of the energy release process.

In this paper, we show how a rich lexico-semantic network which Has been built using serious games, JeuxDeMots, can help us in grounding our semantic ontologies in doing formal semantics using rich or modern type theories (type theories within the tradition of Martin Löf). We discuss the issue of base types, adjectival and verbal types, hyperonymy/hyponymy relations as well as more advanced issues like homophony and polysemy. We show how one can take advantage of this wealth of lexical semantics in a formal compositional semantics framework. We argue that this is a way to sidestep the problem of deciding what the type ontology should look like once a move to a many sorted type system has been made. Furthermore, we show how this kind of information can be extracted from a lexico-semantic Network like JeuxDeMots and inserted into a proof-assistant like Coq in order to perform reasoning tasks.

Opis:
We report the timeline of the solar radio burst Type II that formed but fragmented at certain point based on the eruption of the solar flare on 13th November 2012 at 2:04:20 UT. The active region AR 1613 is one of the most active region in 2012. It is well known that the magnetic energy in the solar corona is explosively released before converted into the thermal and kinetic energy in solar flares. In this work, the Compound Astronomical Low-frequency, Low-cost Instrument for Spectroscopy Transportable Observatories (CALLIISTO) system is used in obtaining a dynamic spectrum of solar radio burst data. There are eight active regions and this is the indicator that the Sun is currently active. Most the active regions radiate a Beta radiation. The active regions 1610, 1611 and 1614 are currently the largest sunspots on the visible solar disk. There is an increasing chance for an isolated M-Class solar flare event. It is also expected that there will be a chance of an M flare, especially from AR 1614 and 1610. Although these two observations (radio and X-rays) seem to be dominant on the observational analysis, we could not directly confirmed that this is the only possibility, and we need to consider other processes to explain in detailed the injection, energy loss and the mechanism of the acceleration of the particles. In conclusion, the percentage of energy of solar flare becomes more dominant rather than the acceleration of particles through the Coronal Mass Ejections (CMEs) and that will be the main reason why does the harmonic structure of type II burst is not formed. This event is one fine example of tendencies solar radio burst type III, which makes the harmonic structure of solar radio burst type II fragmented.

Leaf hair types in Polish selected taxa from Potentilla subsect. Collinae Juz., i.e. P. collina Wibel s.str., P. silesiaca Uechtr. P. thyrsiflora Hillsen ex Zimmeter, P. wimanniana Gilnther and Schummel, P. leucopolitana P.J. Milller and P. leucopolitana P.J. Milller x P. incana P. Graebner were studied. A total of five unicellular hair types could be distinguished, based on the structure of the hair: straight, involuted, crispate, curved and stellate. The occurrence of involuted, curved and stellate hairs was observed for the first time for the majority of investigated taxa. There is a variation in density, position, as well as in the number of arms of stellate hairs. Although they are difficult to see without a stereo microscope, these differences seem to be systematically important. The study of hair types on surfaces of leaves supports the opinion that P. collina s.lato is a hybrid between P. argentea L. s.la-to, P. tabernaemontani Ascherson and P. incana P. Gaertner. Hairs form consistent characters which are highly suited for systematic purposes. The key to Polish taxa based on leaf hair types is given as well.

The results of a systematic study of the influence of meridional contours overlap in the stator-rotor axial interspace of the impulse and reactive type stages of a high-pressure steam turbine on the flow structure and gas-dynamic efficiency of the flow part are introduced. The studied flow parts of the impulse and reactive stages are typical for high-power high-pressure steam turbines. It is shown that the stages that have no overlaps and/or have a smooth shape of meridional contours have the best gasdynamic efficiency, and the most negative effect on the flow part is caused by the presence of caverns in the stator-rotor interspace. For cases where, due to technological limitations, it is impossible to avoid the presence of caverns and overlaps with a sharp (step-wise) change in the shape of the meridional contours, it is recommended to perform overlaps with positive size of overlap values near the rotor blades.

Opis:
The classic interval has precise borders A = [a, ā] . Therefore, it can be called a type 1 interval. Because of great practical importance of such interval data, several versions of type 1 interval arithmetic have been created. However, sometimes precise borders a and ā of intervals cannot be determined in practice. If the borders are uncertain, then we have to do with type 2 intervals. A type 2 interval can be denoted as AT2 = [aL, aR], [āL, āR]. The paper presents multidimensional decomposition RDM type 2 interval arithmetic (D-RDM-T2-I arithmetic), where RDM means relative-distance measure. The decomposition approach considerably simplifies calculations and is transparent for users. Apart from this arithmetic, examples of its applications are also presented. To the authors’ best knowledge, no papers on this arithmetic exist. D-RDM-T2-I arithmetic is necessary to create type 2 fuzzy arithmetic based on horizontal µ-cuts, which the authors aim to do.

An algebra A = ⟨A, ∨, ∧, →, 0, 1⟩ is a semi-Heyting algebra if ⟨A, ∨, ∧, 0, 1⟩ is a bounded lattice, and it satisfies the identities: x ∧ (x → y) ≈ x ∧ y, x ∧ (y → z) ≈ x ∧ [(x ∧ y) → (x ∧ z)], and x → x ≈ 1. ℋ denotes the variety of semi-Heyting algebras. Semi-Heyting algebras were introduced by the second author as an abstraction from Heyting algebras.  They share several important properties with Heyting algebras.  An identity of associative type of length 3 is a groupoid identity, both sides of which contain the same three (distinct) variables that occur in any order and that are grouped in one of the two (obvious) ways. A subvariety of ℋ is of associative type of length 3 if it is defined by a single identity of associative type of length 3. In this paper we describe all the distinct subvarieties of the variety ℋ of asociative type of length 3.  Our main result shows that there are 3 such subvarities of ℋ.

This article will focus on the solar prominences that occur during the 4th September 2015. On that day, there were two sunspots on the surface of the sun, which were AR2409 and AR2410. These two active regions did not produce any threat for strong flare and thus the solar activity was very low. The prominences that will be focused were both occurred at 0353 UT and 0427 UT respectively. There were minor (G1) geomagnetic storm observed on that day. For solar prominences that occurred at 0353 UT, solar radio burst type (SRBT) IV was detected by CALLISTO spectrometer. From the CALLISTO, two bursts at low intensities with the duration of about 7 minutes for the first burst of 280-320 MHz and 6 minutes for the second burst of 360-430 MHz were observed. For the first burst, energy calculated was between 1.855 x 10 -25 J and 2.12 x 10 -25 J with the drift rate of 0.095 MHz/s. For second burst, the energy obtained was between 2.385 x 10 -25 J and 2.849 x 10 -25 J with the drift rate of 0.194 MHz/s. At 0427 UT, SRBT III was recorded with a frequency of 240-350 MHz with the energy which was obtained between 1.590 x 10 -25 J and 2.319 x 10 -25 J. The drift rate of this type of burst was 0.61 MHz/s. During this event, the solar wind value was 499.3 km/Sec with the proton density of 15.1 protons/cm3.

Opis:
The solar flare and Coronal Mass Ejections (CMEs) are well known as one of the most massive eruptions which potentially create major disturbances in the interplanetary medium and initiate severe magnetic storms when they collide with the Earth‟s magnetosphere. However, how far the solar flare can contribute to the formation of the CMEs is still not easy to be understood. These phenomena are associated with II and III burst it also divided by sub-type of burst depending on the physical characteristics and different mechanisms. In this work, we used a Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy in Transportable Observatories (CALLISTO) system. The aim of the present study is to reveal dynamical properties of solar burst type II and III due to several mechanisms. Most of the cases of both solar radio bursts can be found in the range less that 400 MHz. Based on solar flare monitoring within 24 hours, the CMEs that has the potential to explode will dominantly be a class of M1 solar flare. Overall, the tendencies of SRBT III burst form the solar radio burst type III at 187 MHz to 449 MHz. Based on solar observations, it is evident that the explosive, short time-scale energy release during flares and the long term, gradual energy release expressed by CMEs can be reasonably understood only if both processes are taken as common and probably not independent signatures of a destabilization of pre-existing coronal magnetic field structures. The configurations of several active regions can be sourced regions of CMEs formation. The study of the formation, acceleration and propagation of CMEs requires advanced and powerful observational tools in different spectral ranges as many „stages‟ as possible between the photosphere of the Sun and magnetosphere of the Sun and magnetosphere of the Earth. In conclusion, this range is a current regime of solar radio bursts during CMEs events.

Aims. The aim of our study was to evaluate which of the pharmacotherapeutic methods that are frequently used to treat type 2 diabetes is associated with the most beneficial profile in relation to pro-atherogenic homocysteine levels. Patients and Methods. We measured the serum homocysteine level in 182 patients with type 2 diabetes treated with metformin (89), treated with insulin in combination with metformin (31), receiving sulfonylureas (31) and treated conventionally with insulin (31). The total homocysteine levels in the serum were assayed. To exclude the influence of selected metabolic and anthropometric factors on the differences between the examined groups, multivariate analysis of covariance was used (ANCOVA). In this analysis, serum homocysteine concentration was the dependent variable, while diabetes duration, waist circumference, HbA1c, 1,5-anhydro-D-glucitol, fasting glycaemia and peptide C were used as covariates. Results. The serum homocysteine levels in patients treated with insulin in monotherapy were significantly higher than what was observed in the metformin treated subjects and in the patients receiving insulin combined with metformin. The analysis of covariance also confirmed that the differences between the therapeutic groups were affected by waist circumference and the C-peptide levels. Conclusion. We conclude that conventional insulin therapy may have a negative effect on pro-atherogenic homocysteine levels in patients with type 2 diabetes. This study revealed that pro-atherogenic homocysteine levels may not only be modified by pharmacotherapy of type 2 diabetes, but also by beta cell secretory function and abdominal obesity.

Opis:
Studies on type I procollagen produced by skin fibroblasts cultured from twins with lethal type II of osteogenesis imperfecta (OI) showed that biosynthesis of collagen (measured by L-[5-3H]proline incorporation into proteins susceptible to the action of bacterial collagenase) was slightly increased as compared to the control healthy infant. SDS/PAGE showed that the fibroblasts synthesized and secreted only normal type I procollagen. Electrophoretic analysis of collagen chains and CNBr peptides showed the same pattern of electrophoretic migration as in the controls. The lack of posttranslational overmodification of the collagen molecule suggested a molecular defect near the amino terminus of the collagen helix. Digestion of OI type I collagen with trypsin at 30°C for 5 min generated a shorter than normal α2 chain which melted at 36°C. Direct sequencing of an asymmetric PCR product revealed a heterozygous single nucleotide change C→G causing a substitution of histidine by aspartic acid in the α2 chain at position 92. Pericellular processing of type I procollagen by the twin's fibroblasts yielded a later appearance of the intermediate pC-α1(I) form as compared with control cells.

Given a positive measure μ in $ℝ^n$, there is a natural variant of the noncentered Hardy-Littlewood maximal operator $M_{μ}f(x) = sup_{x ∈ B} 1/μ(B) ʃ_{B} |f|dμ$, where the supremum is taken over all balls containing the point x. In this paper we restrict our attention to rotation invariant, strictly positive measures μ in $ℝ^n$. We give some necessary and sufficient conditions for $M_μ$ to be bounded from $L^{1}(dμ)$ to $L^{1,∞}(dμ)$.

Triketone herbicides are inhibitors of 4-hydroxyphenylpyruvate dioxygenase (HPPD), a key enzyme of the tyrosine transformation pathway, common for plants and animals. One of these herbicides, 2-[2-nitro-4-(trifluoromethyl)benzoyl]-1,3-cyclohexanedione (NTBC), is so selective and efficient that it can be applied as a medicine in a hereditary metabolic disease - tyrosinemia type I. In this paper the available information concerning the molecular mechanism of HPPD inhibition by NTBC, originating from experimental investigations as well as theoretical modeling, has been collected. It is supplemented by results of additional theoretical DFT and/or MP2 calculations of the energetic effects of individual elementary molecular transformations. All these data are discussed and a consistent picture of HPPD inhibition by NTBC is proposed.

Boussinesq type equations

Opis:
The paper concerns the non-linear problem of description of shallow-water waves of finite amplitude. The description is based on the conservation-law formulation, which seems to be particularly convenient in constructing an approximate solution of the problem considered. The analysis is confined to the one-dimensional case of waves propagating in water of constant depth. In the model considered, vertical acceleration of the fluid is taken into account, and thus, the fundamental equations of the problem are similar to those given by Boussinesq (Abbott 1979). The equations differ from those frequently used in shallow-water hydrodynamics which are based on the assumption of hydrostatic pressure. An approximate solution of the problem is constructed by means of a perturbation scheme with the third order expansion of the equations with respect to a small parameter. It is demonstrated that the solution procedure may be successfully applied only within a certain range of the two ratios defining wave height to water depth and the depth to wave length, respectively.

Abstract: Results of the metallurgy study on three, two-edged swords from a cremation burial ground in Czelin, representing the Pompeii, Lachmirowice-Apa and Vimose-Illerup types indicate a variability in the material used as well as in technique of their production, and thus in the quality of the specimens. Two of them were made of a single piece of metal with low (specimen of the Lachmirowice-Apa type) or medium quality (specimen of the Pompeii type). A much higher level of craftsmanship is represented by the third sword of the Vimose-Illerup type, precisely forged from several pieces of diverse, high-quality material, representing the so-called pattern welding technique.

Opis:
We extend the notion of the exocenter of a generalized effect algebra (GEA) to a generalized pseudoeffect algebra (GPEA) and show that elements of the exocenter are in one-to-one correspondence with direct decompositions of the GPEA; thus the exocenter is a generalization of the center of a pseudoeffect algebra (PEA). The exocenter forms a boolean algebra and the central elements of the GPEA correspond to elements of a sublattice of the exocenter which forms a generalized boolean algebra. We extend the notion of central orthocompleteness to GPEA, prove that the exocenter of a centrally orthocomplete GPEA (COGPEA) is a complete boolean algebra and show that the sublattice corresponding to the center is a complete boolean subalgebra. We also show that in a COGPEA, every element admits an exocentral cover and that the family of all exocentral covers, the so-called exocentral cover system, has the properties of a hull system on a generalized effect algebra. We extend the notion of type determining (TD) sets, originally introduced for effect algebras and then extended to GEAs and PEAs, to GPEAs, and prove a type-decomposition theorem, analogous to the type decomposition of von Neumann algebras.

The aim of this paper is to present a constructive methodology and algorithms for operations with fuzzy sets of type 2. The need to elaborate this methodology came from practical problems of Decision Making. To realize the methodology, some simplifications of the problem have been introduced. Particularly, only the trapezium form of membership functions was used. To highlight the difference between the proposed approach and the classical theory of fuzzy sets of type 2, the terms "hyperfuzzy set" and "hyperfuzzy function" have been introduced. Some base situations of hyperfuzzy functions with real arguments and real functions of hyperfuzzy arguments are performed.

Opis:
Cechą współczesnych empirycznych badań jakościowych w naukach społecznych, w tym w pedagogice, są ich aspiracje teoretyczne. Za jeden ze sposobów tworzenia teorii uznaje się budowanie typologii. W literaturze przedmiotu „obowiązuje” rozróżnienie na typy idealne i typy realne (empiryczne). Autorka omawiając specyfikę obu typów, zwraca uwagę, iż podział ten jest umowny. Wynika z większej wagi nadawanej jednemu z komponentów typu: komponentowi teoretycznemu lub empirycznemu. W rzeczywistości oba komponenty współwystępują. Związek teorii z empirią jest znakiem nowoczesnych dyscyplin naukowych. Chodzi o to, by ich teorie można było oceniać w świetle danych empirycznych, i o to, by danym empirycznym nadać sens. Utrzymywanie opozycji typ idealny – typ empiryczny nie wydaje się korzystne, przysłania bowiem wspólny „komponent” obu typów, a zaakceptowany porządek osłabia potrzebę pracy myślowej. Autorka sygnalizuje koncepcję typu idealnego M. Webera, koncepcję A. Schütza przyjmującego, że typiki naukowe są wtórne wobec typik codzienności, omawia tworzenie typologii poprzez grupowanie cech przedmiotów, a także funkcje typologii w metodzie dokumentarnej, opierającej się na socjologii wiedzy K. Mannheima.
The characteristic feature of empirical qualitative research in social sciences, including pedagogy, are their theoretical aspirations. Building a typology is said to be one way of creating a theory. In the subject literature there is a differentiation between ideal and real (empirical) types. The author, discussing both types, emphasises that this division is contractual. It results from paying more attention to one of the type components: either a theoretical or an empirical one. As a matter of fact, these both components coexist. The relation of theory with empiricism is a sign of modern scientific disciplines. The aim is to evaluate those theories in the light of empirical data, to which a meaning is given. Maintaining the opposition of an ideal type versus an empirical type does not seem to be advantageous, as it blocks out the “common” component of those two types and the accepted order weakens the need of intellectual work. The author signals M. Weber’s concept of ideal type, as well as A. Schütz’ concept, which assumes that scientific typologies are secondary to the typologies of everyday life. She also discusses the creation of typology by the means of grouping the objects’ features and the typology functions in the documentary method, based on sociology of K. Mannheim’s knowledge.

Opis:
W 2010 roku archeolodzy z Muzeum Narodowego w Szczecinie oraz RömischGermanische Kommission DAI Frankfurt/Main przystąpili do realizacji wspólnego programu badawczego pt. „Wcześni Słowianie na ziemi pyrzyckiej”. W latach 60. i 70. XX wieku obszar ziemi pyrzyckiej był objęty intensywnymi prospekcjami przez archeologów z Muzeum Narodowego w Szczecinie. W efekcie tych badań najwcześniejsze stanowiska słowiańskie „horyzontu Dziedzice” datowano na VI–VII wiek. Podjęty wspólnie z kolegami niemieckimi program miał na celu kontynuację badań nad tym zagadnieniem, korygujących obecny stan wiedzy. W pierwszym etapie realizacji projektu przeprowadzono geofizyczne rozpoznanie potencjalnie najbardziej obiecujących stanowisk archeologicznych. Po kwerendzie archiwalnej wytypowano sześć stanowisk, tj. Dziedzice, pow. Myślibórz, stan. 4 (AZP 39-10/50); Strąpie, pow. Myślibórz, stan. 4 (AZP 39-11/2); Moskorzyn, pow. Stargard Szczeciński, stan. 16 (AZP 35-10/40); Dobropole Pyrzyckie, pow. Stargard Szczeciński, stan. 10 i 12 (AZP 36-12/85 i 82); Suchań, pow. Stargard Szczeciński, stan. 18 (AZP 33-13/32); Derczewo, pow. Myślibórz, stan. 3 (AZP 39-08/4). W efekcie przeprowadzonych prospekcji wytypowano do badań wykopaliskowych osadę w Dobropolu Pyrzyckim, pow. Stargard Szczeciński, stan. 12. Prace wykopaliskowe przeprowadzono w sierpniu – wrześniu 2010 roku. Zarejestrowano ogółem 37 obiektów archeologicznych na przebadanym obszarze 5,25 ara. Przeważająca część z nich składa się na osadę wczesnośredniowieczną. Najliczniejszą grupę stanowią jamy najczęściej o nieokreślonym przeznaczeniu (21), dołki posłupowe (8) oraz paleniska (5). Trzy obiekty datowano na okres halsztacki. Na szczególną uwagę wśród obiektów wczesnośredniowiecznych zasługują trzy ziemianki wczesnośredniowieczne. W trakcie badań pozyskano ogółem 2832 fragmenty ceramiki. Chronologicznie ceramika niezdobiona odpowiada materiałom typu Sukow-Dziedzice, natomiast wśród fragmentów ornamentowanych uwagę zwraca ceramika nawiązująca do typu Menkendorf.
In 2010 archaeologists from the National Museum in Szczecin together with Römisch-Germanische Kommission Deutsche Archäologische Institut Frankfurt/Main set about working together on a research project called the Early Slavs in the Pyrzyce Region. Already in the 1960s and the 1970s the area of the Pyrzyce Region had been intensely examined by researchers from the institution in Szczecin. It resulted in discovering the earliest Slavic sites of so-called the Dziedzice horizon, which have been dated to the 6th–7th century. The current Polish-German research project was aimed at continuing examining this matter, including verifying the chronology that had been previously established. In the first stage of the project geophysical survey of potentially the most promising archaeological sites has been carried out. Based on the archival research six sites have been selected: Dziedzice 4, Myślibórz County, (AZP 39-10/50); Strąpie 4, Myślibórz County, (AZP 39-11/2); Moskorzyn 16, Stargard Szczeciński County, (AZP 35-10/40); Dobropole Pyrzyckie 10 and 12, Stargard Szczeciński County, (AZP 36-12/85 and 82); Suchań 18, Stargard Szczeciński County, (AZP 33-13/32); Derczewo 3, Myślibórz County, (AZP 39-08/4). The settlement at Dobropole Pyrzyckie 12, Stargard Szczeciński County, was selected for excavation. The work was carried out in August and September 2010 and covered in total the area of 5,25 ares where 37 archaeological features have been recorded. Most of them belong to the early medieval settlement. The most numerous group consisted of pits out of which majority was unidentified in terms of usage (21), postholes (8) and hearths (5). Three features have been dated to the Hallstatt period. Three early medieval dugouts are worthy noticing. During the research 2832 fragments of pottery in total were found, including fragments of undecorated pottery vessels which correspond to the materials of the Sukow-Dziedzice type as well as decorated ones which make reference to the Menkendorf type.

Introduction. Diabetes as a non-infectious chronic metabolic disease is a problem of the contemporary world, including Poland. Behaviour therapy plays an important role in its treatment, i.e. proper diet and regular physical activity. Patient’s knowledge of nutrition principles is also an essential complement to the treatment, reducing the risk of late complications of diabetes. Objective. Assessment of the nutrition knowledge of patients with type 1 and type 2 diabetes. Materials and method. The study involved 300 randomly selected patients from Rzeszów and the surrounding area (135 patients with type 1 diabetes and 165 patients with type 2 diabetes) aged 8–78.The analysis was made using a survey questionnaire prepared by the authors of the study, conducted in the period July – December 2011. Results. The survey revealed that patients with type 1 diabetes have greater nutrition knowledge and knowledge about diabetes than patients with type 2 diabetes. On the other hand, they are less likely to comply with the recommendations of the diet prescribed by a doctor or a dietician. Conclusions. Patients with diabetes, regardless of age, type of diabetes, gender, or disease duration require continuous broadening of diabetes knowledge. Systematic training will teach patients proper eating habits related to their diet and lifestyle.

Opis:
Observations of type II and III solar bursts indicate that while type III bursts may appear at any altitude, from the very low corona into interplanetary space, type II solar bursts do not act the same way. This work focuses on recent observations in the radio region on the low frequency region from 45 MHz to 870 MHz. Our analysis employed the accuracy of the daily solar burst measurements of e-CALLISTO network. It was found that solar burst type II explode quite minimum with 1-2 events from 2006 - 2010. However, the data 2011 for solar burst type II increases drastically with 16 events has been recorded. The occurrences of Coronal Mass Ejections (CMEs) events are also increasing up to four times in 2011. Most of the both events can be observed in the range of 150 MHz till 500 MHz. Overall, we can say that the range of photon energy for solar burst type III is between 7.737 x 10-7 eV to 1.569 x 10-6 eV. In the case of solar burst type II, the distribution of energy is much smaller with 1.596 x 10-6 eV to 6.906 x 10-6 eV. Detailed investigation of solar burst will concern the 2011 data seem to show a significant trend for both types. We showed that the increasing of both solar burst events via years implies directing an increasing of solar activities including sunspot number, solar flare and Coronal Mass Ejections (CMEs) events. It is expected that both types will increase gradually in the beginning of 2014.

Opis:
In this paper generalized classes of modified ratio type and regression-cum-ratio type estimators of the finite population mean of the study variable are suggested in the presence of two auxiliary variables in simple random sampling without replacement when the population means of the auxiliary variables are known in advance. Some special cases of the generalized estimators are compared with respect to their biases and efficiencies both theoretically and with the help of some natural populations.

Opis:
The present study proposes a class of product-type exponential estimators for estimating the population mean of the study variable, using known values of some population parameters of an auxiliary character, under the simple random sampling without replacement (SRSWOR) scheme. Furthermore, the study also proposes a modified exponential estimator based on both the ratio-type and the product-type exponential estimators. Properties of the proposed estimators, under the SRSWOR scheme, are obtained up to first order approximation. The modified exponential estimator under optimum conditions is shown to be more efficient than the simple sample mean and the ratio-type and product-type exponential estimators. The theoretical results are supported by an empirical illustration.

Opis:
The problems of both single and multiple delays for neutral-type uncertain systems are considered. First, for single neutral time delay systems, based on a Razumikhin-type theorem, some delay-dependent stability criteria are derived in terms of the Lyapunov equation for various classes of model transformation and decomposition techniques. Second, robust control for neutral systems with multiple time delays is considered. Finally, we demonstrate numerical examples to illustrate the effectiveness of the proposed approaches. Compared with results existing in the literature, our methods are shown to be superior to them.

Opis:
This paper proposes a modified particle swarm optimization (PSO) algorithm that can be used to solve a variety of fuzzy nonlinear equations, i.e. fuzzy polynomials and exponential equations. Fuzzy nonlinear equations are reduced to a number of interval nonlinear equations using alpha cuts. These equations are then sequentially solved using the proposed methodology. Finally, the membership functions of the fuzzy solutions are constructed using the interval results at each alpha cut. Unlike existing methods, the proposed algorithm does not impose any restriction on the fuzzy variables in the problem. It is designed to work for equations containing both positive and negative fuzzy sets and even for the cases when the support of the fuzzy sets extends across 0, which is a particularly problematic case.

Opis:
On field requirements for headlights are significantly dependent on type approval requirements. But the type approval requirements are described differently than exploitation requirements. They assume that basic photometrical requirements tested during type approval are met. But this assumption is not described and checked. Finally on field real headlamp photometric values could be significantly different than expected because depends on factors as light source geometry tolerance, headlamp design sensitivity for filament geometry, possible precision of aiming/levelling method. Moreover drivers and services awareness of this situation is not meaningful. As result safety during nighttime traffic is significantly deteriorated. In paper are described important factors concerned way of defining present type approval requirements. It concern the way of defining of photometric criteria for vertical measuring screen in fixed distance, choice of points and zones for assessment, limits and their restrictions. Also differentiation of requirement in dependence on light source used is analysed as well as some other important factors. The important issue is glare caused by headlights and their restriction in type approval requirements. It is also analysed influence on headlights performance on field conditions as result of lack of reference to imperfect but defined type approval photometric requirements. The visual aiming on the base of cut-off line and subjective judgement is the only way to allow use of vehicle. Moreover as well service as drivers believes that this is sufficient for safety driving at night with speeds allowed by common road traffic law.

Accentual parallelism between verbs suffixed with -і- // -ію- / -іє- and -и- // -ю- / -я- / -и-The article presents an attempt to identify the pattern according to which pairs of common-rooted verbs ending with -іти and -ити (of the types білíти, жовтíти, чорнíти and біли́ти, жовти́ти, чорни́ти) are stressed in present-day Ukrainian. For instance, why do we have a verb with a movable stress біли́ти – білю́, бíлиш and a verb with a fixed inflection stress чорни́ти – чорню́, чорни́ш among the verbs with -ити in modern Ukrainian? They are both derivatives of the stem-stressed adjectives білий and чорний and the respective derivative verbs with -іти have the accentual features of the corresponding adjectives: білíти – білíю, білíєш and чорнíти – чорнíю, чорнíєш. The author believes that primary correlation of the accentual features of the verbs of both types is reflected by the pairs чорнíти – чорни́ти and so on. But nowadays this pattern is already violated in many cases because the verbs with -ити in modern Ukrainian are intensively losing their ultimate stress and developing a movable stress or a fixed stem stress instead. For example, the primary accentual correlation красíти – краси́ти – крашу́, краси́ш is being changed to the correlation красíти – крáсити – крáшу, крáсиш. Likewise, the modern correlation оголíти – оголи́ти – оголю́, огóлиш has replaced the former one оголíти – оголи́ти – оголю́, оголи́ш etc. Paralelność w akcentowaniu czasowników z sufiksami -і- // -ію- / -іє- oraz -и- // -ю- / -я- / -и-Artykuł stanowi próbę wyodrębnienia wzorca, zgodnie z którym we współczesnym języku ukraińskim akcentowane są pary czasowników o identycznym rdzeniu i końcówce -іти i -ити (typu білíти, жовтíти, чорнíти i біли́ти, жовти́ти, чорни́ти). Rozważa się w nim na przykład, czemu we współczesnym ukraińskim wśród czasowników zakończonych na -ити obok czasownika z ruchomym akcentem біли́ти – білю́, бíлиш występuje czasownik ze stałym akcentem końcówkowym чорни́ти – чорню́, чорни́ш. Oba te czasowniki są derywatami przymiotników o akcencie rdzeniowym: білий i чорний, a odpowiadające im czasowniki zakończone na -іти akcentowane są analogicznie do przymiotników, od których się wywodzą: білíти – білíю, білíєш i чорнíти – чорнíю, чорнíєш. Zdaniem autora pierwotna korelacja w akcentowaniu czasowników obu omawianych typów znajduje odzwierciedlenie w parach typu чорнíти – чорни́ти. Obecnie jednak ów wzorzec akcentowy języka ukraińskiego w wielu wypadkach ulega zaburzeniu, czasowniki zakończone na -ити coraz częściej bowiem tracą akcent końcowy na rzecz akcentu ruchomego lub stałego akcentu rdzeniowego. Przykładem może być pierwotna korelacja akcentów красíти – краси́ти – крашу́, краси́ш, która ulega zastąpieniu korelacją красíти – крáсити – крáшу, крáсиш. Podobnie współczesna korelacja оголíти – оголи́ти – оголю́, огóлиш zastąpiła występującą dawniej korelację оголíти – оголи́ти – оголю́, оголи́ш itd.

Atypical but real practical problems relating to the dynamics of block-type foundations for machines are considered using the deterministic approach and assuming that the determined parameters are random variables. A foundation model in the form of an undeformable solid on which another undeformable solid modelling a machine is mounted via viscoelastic constraints was adopted. The dynamic load was defined by a harmonically varying signal and by a series of short duration signals. The vibration of the system was investigated for the case when stratified ground (groundwater) occurred within the side backfill was present. Calculation results illustrating the theoretical analyses are presented.

Opis:
Unemployment is a significant social problem which has numerous negative health consequences. Findings of numerous researches provide  data on the range of the consequences of unemployment with risk of health deterioration being one of the most important. Unemployment remains an area of interest for the following fields of science: psychology, economics, sociology. More and more researches prove that there is a link between the increase of disease occurrence and death rate and long-term unemployment. Both in Poland and all over the world a steady increase in the incidence of type 2 diabetes is being observed. World Health Organization (WHO) estimates that, taking into consideration present dynamics of changes, in 2025 there will be 300 million people diagnosed with diabetes. That is why a diabetes epidemic is such a topical issue, and according to some epidemic data this epidemic is starting to reach Poland as well. Data provided by IDF (International Diabetes Federation) show that in Poland the percentage of diabetes patients is 9,1% of the whole population and it is a little higher than the European average (8,6%). It is predicted that by 2015 the percentage will rise to 11%. Identification of adverse health behaviors and introducing actions promoting health in a given population group can prove to be beneficial for the present condition of members of a given group as well as decrease the risk connected with the occurrence of diseases associated with the progress of civilization in the future. The aim of the article is to indicate type 2 diabetes risk factors among the unemployed in Poland.

Opis:
Type 1 diabetes is a metabolic disorder whose treatment depends not only on the administration of insulin and diabetic control, but also on properly applied physical activity to improve insulin sensitivity and thus the patient’s condition. In order to fulfill this role, physical exercise must be systematic and properly administered. An adequate intensity depends on the physical fitness level of the patient, which may be determined in a six-minute walk test. Before a training cycle, the patient should be subjected to basic clinical tests. The intensity of training may be determined by the Karvonen or Strunz formula to precisely specify the training heart rate (60–75% of maximum heart rate, depending on the condition of the individual). Blood sugar levels should be measured before and after the training session, while during exercise a heart rate monitor should be used. All these measures should help prevent the occurrence of adverse effects such as hypoglycemia.

Introduction: Motorcycles in Poland become more and more popular also as convenient means of transport, especially in large cities. Factors influencing on driver during riding the motorcycle are assumed to cause spinal pain in motorcyclist. These factors may vary in motorcycles of different construction or purpose. Few information is available about spinal pain connected with riding a motorcycle. The aim of this study was the assessment of occurrence and intensity of spinal pain in motorcyclists depending on motorcycle type. Material and methods: The study group consisted of 2,124 motorcyclists aged 19-79 yrs., using motorcycle with an engine size bigger than 50 ccm and participating in minimum 1 riding season. An original, on-line available questionnaire composed of questions regarding riding a motorcycle and ailments of all parts of the spine was used. The results underwent statistical analysis using the Statistica 10.0. Results: The results showed that 58.4% respondents experienced pain of at least one part of spine during riding the motorcycle. The biggest percentage (51.1%) of persons with spinal pain in general was found out in cross/enduro type users. Neck pain was significantly connected with riding the sport motorcycle (p=0.001). Conclusions: Spinal pain in motorcyclists depends on the motorcycle type.

Opis:
Osteogenesis imperfecta (OI), commonly known as "brittle bone disease", is a dominant autosomal disorder characterized by bone fragility and abnormalities of connective tissue. Biochemical and molecular genetic studies have shown that the vast majority of affected individuals have mutations in either the COL1A1 or COL1A2 genes that encode the chains of type I procollagen. OI is associated with a wide spectrum of phenotypes varying from mild to severe and lethal conditions. The mild forms are usually caused by mutations which inactivate one allele of COL1A1 gene and result in a reduced amount of normal type I collagen, while the severe and lethal forms result from dominant negative mutations in COL1A1 or COL1A2 which produce structural defects in the collagen molecule. The most common mutations are substitutions of glycine residues, which are crucial to formation and function of the collagen triple helix, by larger amino acids. Although type I collagen is the major structural protein of both bone and skin, the mutations in type I collagen genes cause a bone disease. Some reports showed that the mutant collagen can be expressed differently in bone and in skin. Since most mutations identified in OI are dominant negative, the gene therapy requires a fundamentally different approach from that used for genetic-recessive disorders. The antisense therapy, by reducing the expression of mutant genes, is able to change a structural mutation into a null mutation, and thus convert severe forms of the disease into mild OI type I.

Opis:
The advice article is one of the multiple forms of expression in use among general lifestyle magazines aimed at women. Its shape, both style and structure-wise, allows authors to exhaust all the possibilities of persuasive action, which is typical for this group of magazines. The analysis of the materials, taken from ten separate magazines published in the first quarter of 2016, shows that the stylistic range of advice articles is not sophisticated, and so their style is definitely not the most important factor which determines the pleasure of reading. It is also possible to notice that in the down-market magazines (‘Dobre Rady’, ‘Naj’, ‘Pani Domu’, ‘Tina’) this type of an article is usually produced in a form of a corpus (body) made of modules, using the formula of a register. These texts are smaller in size and compositionally more simple (short sentences, usually single sentences or simple relative clauses), with regular use of a question-answer configuration, with exclamations to show emotions, and lists. The act of giving advice is generally based on direct, specific instructions, formulated in a direct style, appropriate for the ‘parenetic’ (persuasive) character of the publication. The editorial boards of magazines such as ‘Olivia’ or ‘Swiat Kobiety’ heavily emphasize the professionalism of their guidance. The authors clearly display their intent to create a more friendly relationship with their female readers, but at the same time encourage them to follow the line of argument more carefully and to think for themselves. In these texts the syntax is more complex, more varied rhetorical terms are used, and the signals of mutual dialogue are present; the factual, graphic and cognitive layer of a publication blends with its practical usage in a much better way.

Opis:
This study aims to investigate crop selection and spatial patterns of agricultural fields in a drought-affected region in Isfahan Province, central Iran. Based on field surveys portraying growth stages of the main crops including wheat, alfalfa, vegetables and fruit trees, three Landsat 8 operational land imager (OLI) images were acquired on March 15 (L1), June 27 (L2) and October 1 (L3), 2015. After performing radiometric and atmospheric corrections, Normalized Difference Vegetation Index (NDVI) maps of the images were produced and introduced to the Multi-Resolution Segmentation algorithm to delineate agricultural fields. An NDVI-based decision algorithm was then developed to identify crops devoted to each field. Finally, a set of landscape metrics including Number of Patches (NP), mean patch size (MPS), mean shape index (MSI), perimeter-to-area ratio (PARA) and Euclidian Nearest Neighborhood Distance (ENN) was utilized to evaluate their respective spatial formation. The results showed that nearly 46% of fields are devoted to wheat indicating that the landscape has been dramatically shifted towards wheat monoculture farming. Moreover, the farmers’ inclination to grow crops in large fields (approximate area of 1 ha) with more regular geometric shapes are considered as an effective way of optimising water use efficiency in areas experiencing significant water shortage.

NIMBY-type conflicts
Opis:
W artykule przedstawiono wybrane zagadnienia problematyki konfliktów typu NIMBY. Są to konflikty wynikające z opozycji społeczności lokalnych wobec lokalizacji, w okolicy ich miejsca zamieszkania, inwestycji, postrzeganych przez nie za uciążliwe. Przedstawiono przestrzenny obraz występowania konfliktów w Polsce (z wyłączeniem dużych i średnich miast), będący wynikiem kwerendy archiwów prasowych (prasy regionalnej i lokalnej) przeprowadzonej dla okresu styczeń 2007 – marzec 2014. Z badań wynika, że najczęstszymi obiektami protestu społeczności lokalnych były inwestycje z zakresu energetyki odnawialnej oraz infrastruktury drogowej. W artykule omówiono również zagadnienia: podstawy prawnej lokalizacji niechcianych inwestycji, etapu rozpoczęcia konfliktów, efektów konfliktów. Na podstawie badań konfliktów lokalnych w 116 gminach okazało się, że nieco więcej było przypadków, że oprotestowywana przez mieszkańców inwestycja ostatecznie nie powstała niż przypadków takich, że powstała. Przedstawiono także różnorodne formy reagowania władz lokalnych na protesty przeciwko kontrowersyjnym inwestycjom, w tym działania skierowanie do mieszkańców czy działania w ramach postępowań prowadzących do lokalizacji inwestycji. Artykuł ten zawiera wyniki badań opublikowanych w 2016 r. w książce z serii Prace Geograficzne, autorstwa M. Bednarek-Szczepańskiej i K. Dmochowskiej-Dudek pt. Syndrom NIMBY na obszarach wiejskich w Polsce. Specyfika i uwarunkowania konfliktów wokół lokalizacji niechcianych inwestycji.
Selected problems related to NIMBY-type conflicts are presented in this article. These conflicts result from local inhabitants’ opposition to location, in the vicinity of their place of living, of investments which they perceive as burdensome. A spatial image of NIMBY-type conflicts occurrence in Poland (excluding medium-size and big cities) is presented as a result of regional and local press query which was carried out for the period 01.2007-03.2014. The study show, that the most frequent objects of inhabitants’ protests were investments in renewable energy and road infrastructure. The following issues are also set out in the article: legal basis of unwanted investments’ location, stages of beginning of conflicts, effects of conflicts. It turned out, on the basis of the study on local conflicts in 116 communes, that there was slighty more cases of conflicts which ended with abandonment of project than conflicts which ended with project realisation. Different forms of local authorities’ response to the protests against controversial investments were identified, including activities directed at inhabitants or activities related to ad-ministrative and planning proceedings. This article contains results of research which were published in 2016 in a book of Geographical Studies series, written by M. Bednarek-Szczepańska and K. Dmochowska-Dudek, The NIMBY syndrome in rural areas of Poland. Specificity and Determinants of conflicts on the location of unwanted investments.

The aim of the undertaken studies was to determine the effect of the herbicides used in the experiment on important features of the consumption values of three varieties of edible potato. Test results come from a field experiment conducted in 2007–2010. The experiment was established as two-factor in the split-plot system in three repetitions. Two factors were tested in the experiment: factor I - potato varieties: Satina, Tajfun, Cekin; factor II – five methods of weed control. Darkening of the pulp of cooked tubers after 10 min, 2 and 24 hours shape the ways of weed control of the plantation and the genotype of the grown varieties. The use of herbicides in 2–5 variants has significantly increased the darkening of the pulp. The Tajfun variation darkened to the lowest degree, and Cekin to the largest degree.

Introduction: Cleft lip and/or palate are the most common face malformations. The clinical picture of these anomalies is very variable. Cleft can include only the lip and/or alveolus, palate or all of these structures can be clefted. Aim: The aim of this paper is to present all particular types of clefts, their relationship to gender and body side in the group of children born in Lodz during the years 1981-2015. Material and method: The study group included 434 patients with facial clefts (218 males and 216 females) in the age between 4 weeks to 18 years who were born in Lodz during years 1981-2015. Results: In the analyzed group, there were 181 palate clefts (41.7%), 156 lip and palate clefts (36%) and 97 lip clefts (22.3%). A detailed analysis of clefts types showed that isolated palate clefts are definitely more frequent in females than males (112 vs. 69), while lip and palate clefts in boys than girls (96 vs. 60), furthermore left-sided clefts are more common than right-sided. Conclusions: During 35 years, the most common type of anomaly in children born in Lodz were palate clefts, followed by lip and palate clefts and the less frequent lip clefts. Palate clefts are more common in girls, while lip and palate clefts in boys. Left-sided clefts are two times more common than right-sided clefts.

The article deals with the results of empirical research on the types of personality moti-vation structure of women who are acquiring higher education in psychology. Two types have been singled out: expressive and impulsive. The expressive type comprises two com-ponents: ideal motivation aimed at life necessities, general activity and social utility, and real motivation aimed at comfort, social status and communication. In the structure of the impulsive type there are three components: real motivation aimed at life necessities, so-cial status, general activity and social utility; real motivation aimed at communication and comfort; creativity motivation aimed at self-development and creative activity. Women belonging to the expressive type of personality motivation structure have more positive self-attitude and a higher level of psychological well-being than women belonging to the impulsive type.

Opis:
Recently, the expand of industrial market has led to have long supply chain network. During the long shipment, the probability of having damaged products is likely to occur. The probability of having damaged products is different between stages and that could lead to higher percentage of damaged products when arrived at retailers. Many companies have rejected the entire shipment because the damaged product percentage was higher than that agreed on. Decision-makers have tried to reduce the percentage of damaged products that happened because the transit, loading unloading the shipment, and natural disasters. Companies started to implement recovery centers in the supply chain network in order to return their system steady statues. Recovery models have been developed in this paper to reduce the damaged percentage at minimum costs to do so. Results show that the possibility of implementing an inspection unit and a recovery centers in the system before sending the entire shipment to the retailer based on examining a sample size that has been selected randomly from the shipment and the minimum cost of committing type I and type II errors. Designing a methodology to minimize the total cost associated with the supply chain system when there is a possibility of damage occurring during shipping is the objective of this research.

Opis:
The complex solar radio burst type III is very related to generation of Coronal Mass Ejections (CMEs). In a previous study, they deduced that the burst was produced by electron beams accelerated in blast wave shocks and injected along open magnetic field lines, similar to the herringbone bursts at metric wavelengths. Usually, if there is another solar flare recorded during complex solar radio burst type III it should be type II burst. Different for this event, the single solar radio burst recorded occur 8 minutes 30 seconds before the complex solar radio burst type III. The Coronal Mass Ejections also recorded occurred 7 hours before the single and complex solar radio burst type III. It is noted that CMEs occurred several hours before this event recorded by the SOHO websites.It is proved that the production of coronal mass ejection contributed to the production of complex solar radio burst type III.

This paper considers the problem of estimating the population mean Y of the study variate y using information on auxiliary variate x. We have suggested a generalized version of Bahl and Tuteja (1991) estimator and its properties are studied. It is found that asymptotic optimum estimator (AOE) in the proposed generalized version of Bahl and Tuteja (1991) estimator is biased. In some applications, biasedness of an estimator is disadvantageous. So applying the procedure of Singh and Singh (1993) we derived an almost unbiased version of AOE. A numerical illustration is given in the support of the present study.

Opis:
Latent autoimmune diabetes in adults (LADA) is a common hybrid disease because it combines features of both type 1 and type 2 diabetes. It is a slow-onset autoimmune disease characterized by an initial relative insulin deficiency. Studies to date indicate a clear genetic overlap between LADA and type 1 diabetes. This is related to the variants in the human leukocyte antigen (HLA) region, which encodes main histocompatibility antigens (MHC). Main histocompatibility antigens are responsible for immunoregulatory processes that are impaired in both type 1 diabetes and LADA, leading to immune system disturbances in individuals. Autoantibodies against pancreatic islets are produced, serving as key markers for distinguishing type 1 diabetes and LADA. They are characterized by occurring at a lower level, as a result of which the destruction of the immune system progresses much more slowly. In the etiopathogenesis of this disease, environmental factors and lifestyle play a significant role, which are also associated with the pathogenesis of type 2 diabetes. In most LADA cases, hyperglycemia does not reach levels as high as in type 1 diabetes, whith contributes to the misdiagnosis of it as type 2 diabetes. So far, an optimal treatment for LADA has not been established. Currently, the proposed treatment focuses on achieving good glycemic control and preventing or delaying the onset of complications. Some authors suggest that this effect can be achieved through the early use of insulin as the first-line pharmacotherapy. Emerging oral hypoglycemic agents used in other types of diabetes may also have a role in the treatment of this condition. Hereby, we discuss the possible usage of Continuous Glucose Monitoring (CGM) in this entity for precise real-time control of blood glucose levels. Despite their many advantages, it is important to remember that these systems still require a certain level of user engagement.
Cukrzyca typu LADA (latent autoimmune diabetes in adults) to powszechna choroba o postaci hybrydowej, która łączy w sobie cechy zarówno cukrzycy typu 1, jak i 2 [1]. Jest to choroba autoimmunologiczna rozwijająca się powoli i charakteryzująca się początkowo względnym niedoborem insuliny. Dotychczasowe badania wskazują na genetyczne nakładanie się cukrzyc typu LADA i typu 1. Ma to związek z wariantami w regionie ludzkich antygenów leukocytarnych (human leukocyte antigen, HLA), które kodują główne antygeny zgodności tkankowej (main histocompatibility antigens, MHC) [2, 3, 4]. Antygeny te odpowiadają za procesy immunoregulujące, które zarówno w cukrzycy typu 1, jak i typu LADA są nieprawidłowe, w wyniku czego dochodzi do zaburzeń w obrębie układu odpornościowego. W przebiegu cukrzycy typu LADA wytwarzane są autoprzeciwciała przeciwko wyspom trzustkowym, które są kluczowymi markerami służącymi do rozpoznawania cukrzyc typu 1 oraz typu LADA [5]. Występują one w dość niskim mianie, w wyniku czego destrukcja układu odpornościowego postępuje stosunkowo wolno. Zaobserwowano również, że w etiopatogenezie cukrzycy typu LADA istotne znaczenie wykazują czynniki środowiskowe i styl życia, które również związane są z patogenezą cukrzycy typu 2 [6]. U większości osób z cukrzycą typu LADA hiperglikemia nie osiąga tak dużych wartości, jak w cukrzycy typu 1, co wpływa na błędne rozpoznanie jej jako cukrzycy typu 2. Dotychczas nie ustalono optymalnego leczenia cukrzycy typu LADA, a proponowane leczenie opiera się na próbach uzyskania dobrej kontroli glikemii oraz zapobieganiu lub opóźnianiu wystąpienia powikłań. Efekt ten według niektórych autorów może być uzyskany poprzez wczesne stosowanie insuliny jako pierwszej linii farmakoterapii. Swoje miejsce w leczeniu tej jednostki chorobowej mogą także znaleźć pojawiające się na rynku doustne preparaty hipoglikemizujące stosowane w innych typach cukrzycy. W pracy została poruszona kwestia wykorzystania systemów ciągłego monitorowania glikemii (continuous glucose monitoring, CGM). Służą one do precyzyjnego kontrolowania poziomu glukozy we krwi w czasie rzeczywistym. Mimo ich wielu zalet należy jednak pamiętać, że systemy te nadal wymagają pewnego poziomu zaangażowania użytkownika.

It is proved that E can be written as G ⨁ H where G and H do not contain any subspace isomorphic to F. In particular, E is not primary. If the subspace F is not normable then the statement holds for other quasinormable Fréchet spaces, e.g., if E is a quasinormable and locally normable Köthe sequence space, or if E is a space of holomorphic functions of bounded type $ℋ_b(U)$, where U is a Banach space or a bounded absolutely convex open set in a Banach space.

Opis:
Cylindrichnus concentricus is a wide spread trace fossil in shallow marine sedimentary rocks of Mesozoic and Cenozoic age. This paper clarifies the ichnotaxonomy of C. concentricus by of fering an emended diagnosis of the ichnogenus and a new diagnosis of the ichnospecies. The broad, bow-shaped architecture of C. concentricus with two openings at the sediment surface suggests that the trace maker was either a filter-feeding animal that captured suspended food particles from the water column or else a surface deposit feeder that employed tentacles or an eversible pharynx to collect nutritious sediment from the surface around one or both of the burrow openings. Although C. concentricus has been reported in a variety of different sedimentary environments around the world, in its type locality in the Cretaceous of Wyoming the trace fossilis found in low-diversity or monoichnospecific beds that exhibit hummocky cross stratification. This occurrence suggests the burrower’s tolerance (or perhaps preference) for an episodic high-energy hydrodynamic environmentre lated to major storms.

Opis:
Phosphodiesterases (PDEs) are a family of enzymes that hydrolyze cyclic nucleotides, thereby modulating cell functions. Three highly selective PDE5 inhibitors (PDE5i), sildenafil, vardenafil and tadalafil, have been developed for treatment of erectile dysfunction (ED). Experimental evidence showed that chronic treatment with sildenafil PDE5i in a mouse model of diet-induced obesity and insulin resistance improved insulin action and decreased circulating fatty acid levels. It has recently been shown that healthy athletes use PDE5i as performance enhancers, hence in the present study we investigated whether the long-lasting PDE5i tadalafil influences energy metabolism in C2C12 skeletal muscle cells by evaluating lactate production, glucose consumption, and citrate synthase and 3-OH acyl CoA dehydrogenase activities. Our data demonstrate that tadalafil is able to modulate energy homeostasis in mouse skeletal muscle cells, depending on the treatment length and dose.

Opis:
In [ABB] Asmar, Berkson and Bourgain prove that for a sequence ${ϕ_j}^∞_{j=1} $ of weak type (1, 1) multipliers in $ℝ^n$ and a function $k ∈ L^1(ℝ^n)$ the weak type (1,1) constant of the maximal operator associated with ${k⁎ϕ_j}_j$ is controlled by that of the maximal operator associated with ${ϕ_j}_j$. In [ABG] this theorem is extended to LCA groups with an extra hypothesis: the multipliers must be continuous. In this paper we prove a more general version of this last result without assuming the continuity of the multipliers. The proof arises after simplifying the one in [ABB] which becomes then extensible to LCA groups.

The dual of a Banach space X is of weak type p if and only if the entropy numbers of an r-nuclear operator with values in a Banach space of weak type q belong to the Lorentz sequence space $ℓ_{s,r}$ with 1/s + 1/p + 1/q = 1 + 1/r (0 < r < 1, 1 ≤ p, q ≤ 2). It is enough to test this for Y = X*. This extends results of Carl, König and Kühn.

Sidon type inequalities

Opis:
Sidon proved the inequality named after him in 1939. It is an upper estimate for the integral norm of a linear combination of trigonometric Dirichlet kernels expressed in terms of the coefficients. Since the estimate has many applications for instance in $L^1$ convergence problems and summation methods with respect to trigonometric series, newer and newer improvements of the original inequality has been proved by several authors. Most of them are invariant with respect to the rearrangement of the coefficients. Although the newest results are close to best possible, no nontrivial lower estimate has been given so far. The aim of this paper is to give the best rearrangement invariant function of coefficients that can be used in a Sidon type inequality. We also show that it is equivalent to an Orlicz type and a Hardy type norm. Examples of applications are also given.

We give a characterization of the irreducible components of a Weierstrass-type (W-type) analytic (resp. algebraic, Nash) variety in terms of the orbits of a Galois group associated in a natural way to this variety. Since every irreducible variety of pure dimension is (locally) a component of a W-type variety, this description may be applied to any such variety.

Introduction and objective: The risk of development colon cancer (CC) is increased significantly among patients with the type 2 diabetes (T2DM). A mechanism responsible for the higher prevalence of CC among diabetic patients may be associated with the immunity system. The aim of this study is to point out the differences in the immunity state in terms of interleukin 2 level among patients with T2DM suffering from CC, and patients without these diseases Material and Methods: 79 patients were included the tests, divided into 4 groups: Group 1–23 people with T2DM, Group 2–23 people with large intestine CC, Group 3–10 people with large CC and T2DM, and Group 4–23 people without T2DM or CC. Each patient had a colonoscopy and those with cancer were confirmed in a histopathological examination. Laboratory measurements included fasting glucose, insulin, C-peptide. The concentration of interleukin-2 in serum was determined with the immunoenzymatic (ELISA) method. Results: The results obtained showed that in patients with T2DM and CC the concentration of interleukin-2 was statistically higher than in the other groups.(4.21±1.61 pg/ml vs. Group 1 -1.64±0.44 pg/ml, Group 2–1.54±0.21 pg/ml, and Group 4–1.70±0.36 pg/ml; p<0.05). Insulin levels, C-peptide and HOMA-IR did not differ significantly between groups, but a tendency was observed to higher values of HOMA-IR and insulin levels in the groups with T2DM alone and T2DM with concomitant CC. Conclusions: The data show differences in the immunity state of patients with T2DM and CC, compared with people without those two diseases. Elevated level of interleukin 2 found in this group, after confirmation in other studies with more patients, could be used as a marker of an increased risk of CC in people with T2DM

Purpose: Type 1 diabetes is a common disease in children and teenagers, but it can occur at any age. This study aimed to determine the awareness and knowledge of type 1 diabetes in parents' to diagnose early. Materials and methods: This study is a descriptive type. Data were collected from 1 April to 1 July 2020 date in Turkey. The study sample consisted of 214 parents who accepted to participate in the study and completed the questionnaire were included in the sample. Results: It was found that the knowledge level of the parents participating in the study about type 1 diabetes was close to medium level (6.10±1.89). The study's findings revealed that there are misperceptions about the incidence of type 1 diabetes in parents. Parents are often confused about the reasons for type 1 and type 2 diabetes. Conclusions: In this study, although the knowledge level of the parents about type 1 diabetes is close to medium level, it is below the intermediate level. It is important and necessary for families to know about type 1 diabetes and its symptoms, observe their child or children and diagnose the disease early.

Introduction and aim. Arterial stiffness (AS) has been associated with reduced cardiorespiratory fitness (CRF). The aim of this study was to verify if there is a relationship between augmentations index (AIx), as an index for AS assessment, and CRF in individuals with type 2 Diabetes Mellitus (T2DM). Material and methods. Observational cross-sectional study including 32 individuals diagnosed with T2DM who performed two evaluations: 1. Arterial stiffness assessment using SphygmoCor and 2. CRF throughout a cardiopulmonary exercise test on a treadmill ergometer. Oxycon Mobile® device was used to obtain oxygen uptake consumption at peak (V˙O2peak); oxygen uptake efficiency slope (OUES) determined by linear regression in reason of the logarithmic transformation of the ventilation and V˙O2 obtained every minute of exercise test. Statistical analysis comprised Pearson’s Correlation and linear regression analysis performed in SigmaPlot. Results. There was a significant correlation between AS and CRF: AIx and OUES; AIx@75 and; OUES. In linear regression, AIx was determinant for V˙O2peak and OUES – AIx and; AIx@75 and V˙O2peak. Conclusion. AS was associated with CRF in individuals with T2DM. These results contribute to the body of evidence linking arterial functional properties to CRF and suggests greater attention for this important index.

Opis:
Flysch deposits of the Ropianka Formation (Wiar and Leszczyny members; Skole Nappe) at Wola Rafałowska include two different sediments that contain exotic pebbles, cobbles and boulders. The first one is a graded conglomerate that contains mostly cobbles of sandstones, gneisses, Štramberk-type limestones, volcanic rocks, pegmatites and ferruginous siltstones. The second one is a pebbly mudstone that contains clasts of sandstones, stone coal, grey mudstones, volcanic rocks, schists, limestones, marls, black mudstones, conglomerates, volcaniclastic rocks and quartz gravels that are floating within a muddy matrix. Genesis of the conglomerate is unclear because it shows features typical of debris flows (poorly sorted, matrix- to clast-supported, large amount of cobble to boulder fraction) as well as high density turbiditic currents (indistinct normal gradation, small amount of cohesive material, crushed clasts that suggest interaction between grains during transportation and at least partly turbulence during flow). The pebbly mudstone represents typical debris flow deposits (large amount of cohesive material, matrix-supported, poorly sorted, lack of grain gradation and traction structures that suggest laminar flow). Limestones occurring in both exotic-bearing sediments show different Upper Jurassic–lowest Cretaceous facies of a carbonate platform, which was involved in the source area of the Skole Basin, along with its basement. They can be interpreted as deposits of: 1) platform-margin reefs and a platform slope: a) partly silicified coral boundstone, b) microbial-coral boundstone, c) silicified sponge-microbial boundstone grading into peloidal-ooidal grainstone with bioclasts, and d) strongly silicified limestone with intraclasts and bioclasts; 2) deeper, platform slope to toe-of-slope area – bioclastic wackstone; 3) inner platform, including: a) partly silicified wackstone with peloids, small intraclasts and bioclasts, and b) microbial bindstone. Moreover, some exotic clasts are built of Albian–Cenomanian wackstone with abundant sponge spicules and planktonic foraminifers, which are interpreted as deeper shelf sediments. Taking into account the geometry of thrust sheets from the site of the exotic-bearing sediments to the edge of the Skole Nappe, along the most probable transportation path, including tectonic/erosional reduction and different variants of slope inclination, the distance of the mass flows attained at least 25–97 km from the shelf edge.

Opis:
We propose a low-level way of combining distributional and logical ideas into a single formal system. This will be an instantiation of a more general system, adding weights to proof rules. These weights will not measure some sort of “confidence the proof is valid”, but Rather act as a way to prefer some proofs over others, where preference can mean “easier to process (for humans)” or “more coherent (combining words that make sense together)”. The resulting system of weighted theorem proving can be implemented either as a best-first proof serach strategy or as a polynomial-time approximation of proof search for NP-complete parsing problems.
