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.

Opis:
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.
