Opis:
W pracy przedstawiono przykład konstrukcji układu niekompletnego split-split-plot (SSP) dla nieortogonalnego doświadczenia trójczynnikowego. Niekompletność układu SSP jest związana z obiektami czynnika trzeciego w kolejności. W pracy układem generującym jest układ zrównoważony o blokach niekompletnych (BIB). Podane są właściwości statystyczne układu finalnego SSP ze szczególnym uwzględnieniem właściwości ogólnego zrównoważenia układu. Zaproponowano analizę statystyczną właściwą dla doświadczeń wielowarstwowych oraz analizę kontrastów. Rozważania zilustrowano danymi wygenerowanymi z doświadczenia ortogonalnego z łubinem.
In the paper a construction method of an incomplete split-split-plot (SSP) design for a non-orthogonal experiment is presented. Incompleteness of the SSP design concerns sub-subplot treatments. Balanced incomplete block (BIB) design is used as generating design in the construction method. Statistical properties of the final SSP design with respect to general balance are given. Multistratum analysis and the analysis of contrasts are proposed as adequate statistical analysis. Considerations are illustrated using data generated from some orthogonal experiment with lupine.

Opis:
Celem pracy jest zaprezentowanie pewnej metody konstrukcji układów niekompletnych typu split-split-plot dla doświadczeń nieortogonalnych z co najmniej trzema czynnikami. W literaturze znanych jest wiele metod konstrukcji układów niekompletnych. Często wykorzystuje się w nich bogatą teorię układów blokowych. Wybierając jeden z nich lub więcej z takich układów do wygenerowania na przykład, niekompletnego układu split-split-plot, szczególny nacisk należy położyć, między innymi, na optymalne wykorzystanie materiału doświadczalnego. Należy również zwrócić uwagę na ewentualność zastosowania obiektów kontrolnych lub wzorca dla jednego lub więcej czynników oraz możliwość takiego zaplanowania doświadczenia, aby najbardziej interesujące dla eksperymentatora kontrasty obiektowe były estymowane z największą precyzją (efektywnością). W pracy powyższe rozważania zilustrowano opisując nowy układ niekompletny typu split-split-plot na przykładzie doświadczenia z pszenicą ozimą. Przedstawiono statystyczne konsekwencje planowania doświadczeń w takim układzie. W analizie statystycznej zastosowano techniki właściwe dla tak zwanych doświadczeń wielowarstwowych oraz korzystano z teorii kontrastów bazowych.
The aim of this paper is to present a method of constructing incomplete split-split-plot type designs for non-orthogonal experiments with at least three factors. Many methods of constructing incomplete designs are known from the literature, often drawing on the rich theory of block designs. When choosing one or more such designs to generate, for example, an incomplete split-split-plot design, special attention must be paid, inter alia, to the optimal use of the experimental material. Consideration should also be given to the possibility of using control or standard treatments for one or more factors, and the possibility of planning the experiment so that the treatment contrasts most interesting to the researcher are estimated with the greatest precision (efficiency). In this paper, the above considerations are illustrated with reference to a new incomplete split-split-plot design for an experiment with winter wheat. The statistical consequences of planning an experiment with such a design are described. The statistical analysis uses techniques appropriate to multi-stratum experiments, as well as the theory of basic contrasts.

For a graph $G$ with a given subgraph $H$, the backbone coloring is defined as the mapping $c : V(G) → \mathbb{N}_+$ such that $|c(u) − c(v)| ≥ 2$ for each edge ${u, v} ∈ E(H)$ and $|c(u) − c(v)| ≥ 1$ for each edge ${u, v} ∈ E(G)$. The backbone chromatic number $BBC(G,H)$ is the smallest integer $k$ such that there exists a backbone coloring with \(max_{v∈V(G)} c(v) = k\). In this paper, we present the algorithm for the backbone coloring of split graphs with matching backbone.

Opis:
A graph G = (V,E) is called a split graph if there exists a partition V = I∪K such that the subgraphs G[I] and G[K] of G induced by I and K are empty and complete graphs, respectively. In 1980, Burkard and Hammer gave a necessary condition for a split graph G with |I| < |K| to be hamiltonian. We will call a split graph G with |I| < |K| satisfying this condition a Burkard-Hammer graph. Further, a split graph G is called a maximal nonhamiltonian split graph if G is nonhamiltonian but G+uv is hamiltonian for every uv ∉ E where u ∈ I and v ∈ K. Recently, Ngo Dac Tan and Le Xuan Hung have classified maximal nonhamiltonian Burkard-Hammer graphs G with minimum degree δ(G) ≥ |I|- 3. In this paper, we classify maximal nonhamiltonian Burkard-Hammer graphs G with |I| ≠ 6,7 and δ(G) = |I| - 4.

Opis:
We continue the study on backbone colorings, a variation on classical vertex colorings that was introduced at WG2003. Given a graph G = (V,E) and a spanning subgraph H of G (the backbone of G), a λ-backbone coloring for G and H is a proper vertex coloring V→ {1,2,...} of G in which the colors assigned to adjacent vertices in H differ by at least λ. The algorithmic and combinatorial properties of backbone colorings have been studied for various types of backbones in a number of papers. The main outcome of earlier studies is that the minimum number l of colors, for which such colorings V→ {1,2,...,l} exist, in the worst case is a factor times the chromatic number (for path, tree, matching and star backbones). We show here that for split graphs and matching or star backbones, l is at most a small additive constant (depending on λ) higher than the chromatic number. Our proofs combine algorithmic and combinatorial arguments. We also indicate other graph classes for which our results imply better upper bounds on l than the previously known bounds.

In this paper, heterogeneous modes of such enunciative insertions are examined in order to refine and / or rectify the theorization on enunciative split in the description of dialogical sequences. The dialogical mechanism of following text sequences are analyzed: “textual island” category (“îlot textuel”), the confirmation adverb “bien”, the cleft sentence (“clivage”) and the reported speech.

Opis:
In 1990, a decentralized local government system was introduced in Hungary. One of the main issues of the system was fragmentation at local level. This paper examines the attempts made by the central government to deal with this issue in the last thirty years. First, the study analyses the municipal splits and maps the dynamics, the reasons, and the environmental and political factors affecting these secessions. Second, it examines the government’s attempts at reform to reduce the effects of fragmentation. The paper argues that the Fidesz-KDNP electoral victory in 2010 was a milestone in the handling of territorial issues: municipal splits became virtually impossible with the new regulation of the secession process, and de facto territorial consolidation reform was carried out through alteration of the local electoral system and functional rescaling and merging of the mayors’ offices.

Opis:
The aim of this paper is a presentation of forms of flexible work organization, commonly known as job sharing, in both its theoretical and empirical aspects, on the basis of research conducted on a sample of sixty-five businesses. Job sharing has been in use since the 1960s. It is not widely known in Poland to date, but is presently being promoted by the EQUAL Common Initiative, where quite a few projects are financed by the European Social Fund. However, not all aspects of job sharing are stressed by the current wave of interest. In fact, they are quite often limited to its social meaning, thus restricting its use and value. This article argues that job sharing is also a form of work organization for specialized work teams, autonomous groups, and team working. Using job sharing in this context brings more benefits to the enterprise. This, in its turn, may serve as a means of enlarging the use of job sharing, including in its social economic meaning.

Opis:
The article presents some numerical results and experimental validation of Split Hopkinson pressure bar (SHPB) tests for welded S40NL steel. The goal of this research is to define material constants for modelling it in FEM. Steel was tested with Charpy impact test to determine properties of material. Next, the joint for welding was prepared. It was welded with electric arc welding method (MAG) with flux-cored wire. Hopkinson bar test is well-known experiment method used to determine material properties at high strain rates. The tests were performed in Institute of Fundamental Technological Research. Material properties for Johnson-Cook material model were obtained. Comparison between experimental results taken in quasi-static conditions and dynamic conditions proves that the behaviour of materials in those two states is quite different. Results from one type of loading condition cannot be used to create a realistic model of material when it is loaded dynamically. Numerical simulation of Hopkinson bars was performed on cylindrical model with known length and accelerated to high speed in direction of incident bar. For the purpose of the simulation, a Finite Element Code LS-DYNA was used. It allows simulation of dynamic response of SHPB system. The results show quite good agreement. The model can be used to simulate weld performance under high strain rate.

Opis:
It is very important to achieve the low particulate and low emissions under high power operation conditions in practical industrial engine and turbine combustion. Several techniques for reducing the emissions have been proposed and a large amount of experimental data has been published. It is well known that the combustion field in practical industrial diesel engine are strongly influenced by the behaviour of injection, distribution of droplets and the premixed ratio of the combustion chamber. As the first step of this study, experiments have been carried out to examine the combustion characteristics of heterogeneous combustion field by using impinging injection and Split injection in a closed chamber. The combustion chamber is equipped with pintle type injection nozzles on each of the opposite walls along the length of the bomb. In this study, we call it “impinging injection” when the injection is performed at same time by two nozzles facing each other and “split injection” when the impinging injection is performed at two different timing. The main conclusions are as follows: 1) the most suitable conditions of injection timing exists for improving the maximum burning pressure and total burning time by using impinging injection; 2) the flame speed can be possible to control by using impinging injection timing from the ignition; 3) the heat release rate for Split injection is larger than that of standard impinging injection.

Opis:
Theoretical background: A share split is an operation that increases the total number of shares. The split is a technical operation and should not affect the market value of the company. The shareholding structure of the company remains unchanged when the shares are split. However, split studies around the world show the occurrence of abnormal returns. Purpose of the article: The article analyses splits based on market data from 2009 to 2021. The aim of the study is to analyse the cumulative average abnormal returns (CAARs) in the periods preceding stock splits on the Warsaw Stock Exchange (WSE). CAARs are analysed in different research variants. The influence of the stock market situation and the frequency of splits on the amount of abnormal returns is examined. Research methods: The research was carried out using event study analysis. The Market-Adjusted Return Model was used to determine abnormal returns. CAARs were calculated for each analysed event window. The statistical significance of abnormal returns was verified by the parametric t test and the non-parametric Corrado rank test. Main findings: The study showed statistically significant positive abnormal returns in the 30-day period preceding the split. The hypothesis that multiple splits cause particularly high increases in the market value of companies has not been confirmed. Research on the reaction to splits depending on the state of the stock market situation did not allow unambiguous conclusions in the case of the periods when the WSE Index (WIG) increased.

Opis:
There is a long line of research in the literature dedicated to word-representable graphs, which generalize several important classes of graphs. However, not much is known about word-representability of split graphs, another important class of graphs. In this paper, we show that threshold graphs, a subclass of split graphs, are word-representable. Further, we prove a number of general theorems on word-representable split graphs, and use them to characterize computationally such graphs with cliques of size 5 in terms of nine forbidden subgraphs, thus extending the known characterization for word-representable split graphs with cliques of size 4. Moreover, we use split graphs, and also provide an alternative solution, to show that gluing two word-representable graphs in any clique of size at least 2 may, or may not, result in a word-representable graph. The two surprisingly simple solutions provided by us answer a question that was open for about ten years.

Opis:
The article analyses the morphological and syntactic expression of the causator (or cause) in the communicative situations of causation of joy in the Polish language. By causation we mean the semantic category which expresses the causal relationships between the fundamentals of non-linguistic reality. The purpose of this study is to analyse the syntactic structure of communicative situations of causation of joy, on the semantic level of which there are such actants as: agent, experiencer, causator (or cause). All of the analysed constructions were divided into three groups: agentive split constructions, agentive unsplit constructions and non-agentive constructions. Split constructions refer to those in which the agent and causator are separate actants, while unsplit ones refer to those in which these semantic roles are combined into one actant. The results of the study show that the most numerous group among the examples is that of non-agentive constructions.

Opis:
A polymeric split Hopkinson pressure bar technique (SHPB) is preferred for testing materials with low mechanical impedance. However, the use of polymeric bars requires additional analysis for data reduction, temperature complications and additional restrictions compared with traditional metallic pressure bars. A viscoelastic material, such as PMMA, exhibits both wave attenuation and wave dispersion. When a wave travels through a polymer bar, the wave amplitude decreases due to attenuation and the wave shape becomes distorted. Therefore, signals measured at given positions on a viscoelastic bar do not represent the pulse at another position along the pressure bar without complex corrections. This paper is concerned with the problem of correction of dispersion and attenuation of waves in the viscoelastic SHPB. It has been demonstrated that the Fast Fourier Transform (FFT) spectral analysis method used to reconstruct wave profiles on the measured signals which are being distorted by wave attenuation and dispersion effects is valid and allows for obtaining satisfactory results for tire rubber.

split-phase protection
Opis:
The stator winding of a hydrogenerator is often made up of coils with multiple turns in the same slot. It is therefore possible for faults to develop between adjacent turns on the same phase (turn-toturn faults). These faults cannot be detected by the stator differential protection because there is no difference between the neutral- and terminal-side currents. Split-phase protection, an overcurrent element responding to the difference between the currents in the winding parallel branches, is typically provided to detect these faults. Ideally, the split-phase element should be sensitive enough to detect a single shorted turn. Despite the fact that the current in this turn can be six to seven times the machine nominal current, the current seen by the split-phase protection can be quite small, in the order of one-twentieth of the generator full-load current. In addition, a spurious split-phase current can be measured due to current transformer (CT) errors, saturation during external faults in particular. Therefore, primary considerations in the application of split-phase protection are the method of measuring the difference in the currents between the parallel branches and the proper selection of the CT used for this purpose.

A split circular element is proposed as a unit cell for reflectarray antennas. The unit cell is derived from a circle divided into four equal sectors. The radius of two oppositely located sectors is then scaled by a certain factor to form the proposed shape. The CST Microwave Studio Suite software simulator was used to investigate the performance of the proposed unit cell, which was evaluated using Floquet port excitation. The designed element's reflection phase range was compared to that of a conventional circular patch. Four scenarios of varied substrate characteristics are investigated for the antenna to establish the best performance parameters. The simulations showed that a basic substrate with a thickness of 0.16 mm and a dielectric constant of 3.2, backed by a 3 mm foam with a dielectric constant of 1.05 and a scaling factor of 0.72 offers a wide phase range of 601.3°. The obtained phase slope is 76.37°/mm or 134°/GHz.

A bipartite-split graph is a bipartite graph whose vertex set can be partitioned into a complete bipartite set and an independent set. The bipartite- splittance of an arbitrary bipartite graph is the minimum number of edges to be added or removed in order to produce a bipartite-split graph. In this paper, we show that the bipartite-splittance of a bipartite graph depends only on the degree sequence pair of the bipartite graph, and an easily computable formula for it is derived. As a corollary, a simple characterization of the degree sequence pair of bipartite-split graphs is also given.

This paper presents a novel complementary CPWfed slotted microstrip patch antenna for operation at 2.4 GHz, 5.2 GHz and 6.3 GHz frequencies. The primary structure consists of the complementary split ring resonator slots on a patch and the design is fabricated on FR-4 epoxy substrate with substrate thickness of 1.6 mm. The described structure lacks the presence of a ground plane and makes use of a number of circular complementary SRRs along with rectangular slots on the radiating patch. The structure provides a wide bandwidth of around 390 MHz, 470 MHz and 600 MHz at the three bands with return losses of -11.5 dB, -24.3996dB and -24.4226 dB, respectively. The inclusion of the rectangular slots in the CSRR based slot antenna with stairecase structure improved the performance with respect to return loss.

The article proposes the concept of experimental dynamic tests of aggregate behavior - sand used as a material for covering temporary protective shelters for the population and civil defense. These shelters are part of the construction shielding infrastructure useful in crisis situations. Laboratory tests of loose soil, including sand, with impact loads are based on the Split Hopkinson Pressure Bar using a clamp. The work describes both this experimental method and the original laboratory stand for impact tests based on a pneumatic launcher with a projectile - bar. This position was built at the Institute of Civil Engineering of the Military University of Technology taking into account the requirements of generally applicable legal provisions. Examples of preliminary experimental research on the behavior of selected aggregate - dry sand under dynamic load - are presented.

Opis:
In the absolute silence of the anechoic chamber John Cage supposedly heard the sounds of his body, and although this interpretation of what happened is questioned, one can draw from this experiment a not necessarily empirical lesson that for the subject the field of the hearable is constituted by a surplus which materialises in a hallucinatory sound. In Arnold Schoenberg’s Erwartung we encounter the opposite kind of surplus: a second of the scream so full that to exhaust it half an hour (the duration of the compositon) and all the intuitive resources of the composer are necessary. This scream is a formless permanent presence tearing the narration apart and materializing as its tears, which places it on the side of (non-empirical) silence. Therefore, because the field of the hearable is split for the subject, “on the side of silence” silence does not exist – it manifests itself as all kinds of sounds, even hallucinatory ones. We can reach the “absolute” silence only if we take the position of the paradoxical object which splits us – only through the surplus of constantly changing and at the same time formless sound, which paradoxically reaches a complex state of stasis. In the pure presence of the split, in which the difference between the subject (consciousness) and the object (sound) is overcome, the external rules of organisation (instinct, reason) are no longer biding, and the subject, who is a dissonance, becomes its own cause.
John Cage w absolutnej ciszy komory bezechowej usłyszał ponoć dźwięki swego ciała i choć interpretacja ta poddawana jest w wątpliwość, można z jego doświadczenia wyciągnąć niekoniecznie empiryczną lekcję, że pole słyszalnego dla podmiotu ustanawiane jest przez nadmiar, który materializuje się w halucynacyjnym dźwięku. W Erwartung Arnolda Schönberga mamy do czynienia z odwrotnego rodzaju nadmiarem: z sekundą krzyku tak pełną, że na jej podtrzymanie przez pół godziny (czas trwania utworu) kompozytor  potrzebuje całej swej inwencji. Krzyk ten jest formalnie bezkształtną permanentną teraźniejszością, rozrywającą narrację i materializującą się jako jej zerwania, a zatem lokującą się po stronie (nieempirycznej) ciszy. Zatem ponieważ pole słyszalnego jest dla podmiotu rozszczepione, „po stronie ciszy” cisza nie istnieje – to tylko rożnego rodzaju dźwięki, nawet halucynacyjne. Do „absolutnej” ciszy możemy dotrzeć jedynie próbując zająć miejsce paradoksalnego obiektu, który nas rozszczepia – poprzez taki rodzaj nadmiaru zmieniającego się jak w kalejdoskopie, a zarazem formalnie bezkształtnego dźwięku, który paradoksalnie osiągnie złożony stan bezruchu. W czystej teraźniejszości obiektu, gdzie zostaje zniesiona różnica między podmiotem (świadomością) a przedmiotem (dźwiękiem), zewnętrzne reguły organizacyjne (instynkt, rozum) przestają obowiązywać i podmiot, który jest rozdźwiękiem, staje się swą własną przyczyną.

Opis:
The paper presents the results of investigation on X30MnAlSi26-4-3 austenitic steel subjected to dynamic compression using the split Hopkinson pressure bar. The strain rate was 3700 s-1. The compression test was also carried out without the use of breaking rings and then true strain was about 0.3. The split Hopkinson pressure bar test take only few milliseconds to complete during which time it is impossible to transfer the excess heat out of the specimen, therefore the test must be carried out in adiabatic conditions and so the increase of the temperature caused by the work of plastic deformation had to be calculated. The stepping load method was used in order to evaluate the effect of adiabatic heating on the properties of steel which allowed to maintain the isothermal deformation conditions. The paper presents the comparison of results obtained during deformation under adiabatic and isothermal conditions in correlation to structure changes occurring in course of dynamic compression.

The paper addresses the problem of overshoot involved in singing accent stylisation. Selected phonetic features indexed as “American” and “Cockney” are analysed in the singing and speaking styles of a British vocalist, Adele. Overshoot, understood as a greater frequency or an exaggerated quality of a given feature, is characteristic of staged performance (Bell and Gibson 2011; Coupland 2007). PRAAT is used to establish the acoustic properties (F1 and F2) of the BATH and TRAP vowels, as well as the presence or absence of the BATH-TRAP split. The results show that Americanisation regarding the BATH-TRAP split in singing is present and the Americanised vowel tokens are “overshot”, having higher F2 frequency compared with the regular British TRAP vowel.

High strain rate experimental tests are essential in a development process of materials under strongly dynamic conditions. For such a dynamic loading the Split Hopkinson Pressure Bar (SHPB) has been widely used to investigate dynamic behaviour of various materials. It was found that for different materials various shapes of a generated wave are desired. This paper presents a parametric study of Split Hopkinson Pressure Bar in order to find striker’s design variables, which influence the pulse peak shape in the incident bar. With experimental data given it was possible to verify the developed numerical model, which was used for presented investigations. Dynamic numerical simulations were performed using explicit LS-Dyna code with a quasi-optimization process carried out using LS-Opt software in order to find striker’s design variables, which influence the pulse peak shape.

Opis:
Materials and their development process are highly dependent on proper experimental testing under wide range of loading within which high-strain rate conditions play a very significant role. For such dynamic loading Split Hopkinson Pressure Bar (SHPB) is widely used for investigating the dynamic behavior of various materials. The presented paper is focused on the SHPB impulse measurement process using experimental and numerical methods. One of the main problems occurring during tests are oscillations recorded by the strain gauges which adversely affect results. Thus, it is desired to obtain the peak shape in the incident bar of SHPB as “smooth” as possible without any distortions. Such impulse characteristics can be achieved using several shaping techniques, e.g. by placing a special shaper between two bars, which in fact was performed by the authors experimentally and subsequently was validated using computational methods.

Opis:
This study investigates the characteristics of self-compacting concrete (SCC) reinforced with recycled fibres and their combination with polypropylene fibres, which can be applied to build protective structures. The split Hopkinson pressure bar (SHPB) method was used to subject the mixtures to high strain rates in the range from 140 to 200 s−1, corresponding to impact loads. It was found that the strain rate sensitivity of both types of mixtures was comparable. The failure pattern confirmed the role of fibres in carrying the loads for strain rates below around 100 s−1.

Opis:
The construction of a homing tour is known to be NP-complete. On the other hand, the Euler formula puts su cient restrictions on plane graphs that one should be able to assert the existence of such tours in some cases; in particular we focus on split Euler tours (SETs) in 3-connected, 4-regular, planar graphs (tfps). An Euler tour S in a graph G is a SET if there is a vertex v (called a half vertex of S) such that the longest portion of the tour between successive visits to v is exactly half the number of edges of G. Among other results, we establish that every tfp G having a SET S in which every vertex of G is a half vertex of S can be transformed to another tfp G′ having a SET S′ in which every vertex of G′ is a half vertex of S′ and G′ has at most one point having a face configuration of a particular class. The various results rely heavily on the structure of such graphs as determined by the Euler formula and on the construction of tfps from the octahedron. We also construct a 2-connected 4-regular planar graph that does not have a SET.

Opis:
On the basis of an empirical study, this article offers some generalisations concerning service systems characteristic of split towns in East-Central Europe. Three frontier urban complexes were examined, including two in the Polish-German borderland, viz. Słubice (Poland) – Frankfurt on the Oder (Germany) and Gubin (Poland) – Guben (Germany), and one in the Polish-Czech borderland, viz. Cieszyn (Poland) – Český Těšín (Czech Republic). The model approach adopted was intended to ensure an insight into the basic properties of the service system in the form of significant factors and connections holding within it. There are many factors giving shape to a service system, but those primarily responsible for differences between the service systems of the examined frontier urban complexes include: (a) the kinds of services offered, (b) specific forms of retail trade, (c) intensity of transborder traffic, and (d) consumers of services. Their unique combination allowed for distinguishing two service systems: in the Polish-German borderland and in the Polish-Czech one. The research also revealed that each system had a double service practice. One, geared to the service of the local population, is fairly stable, and the other – geared to a transborder customer – is different. In the Polish-Czech borderland it is balanced, equally open to the local customer and one from abroad, while in the Polish-German borderland it displays a marked asymmetry in terms of volume and function.

Opis:
Introduction : 400m hurdle run (400m H) is hel d on a track consisting of nine 35 - meter sections separated by ten 91 cm high hurdles. Numerous analyses of the run structure carried out at major events (Olympic Games, World and European Championships) indicate that the tactics of the run consists of tw o parts: "stride pattern" and "split times". Material and methods : The exploration of spacio - temporal structure of the 400m H run included in this study is a meta - analysis, involving all major competitions that were held within the period of 36 years (from 1978 to 2014). The analysis included 260 runs from two periods of time: 1978 - 1999 (Group A; n = 128) and 2000 - 2014 (Group B; n = 132). Detailed data included in the analysis involved temporal parameters (times of particular sections and fragments of the run) and spatial parameters (number of strides). To evaluate the differences between the groups, the analysis of variance (ANOVA) was used. Results : The sports performance level was similar in both groups (53.65 ± 0.72s vs. 0.83s ± 53.60.60). The body buil d was differentiated only by body mass – the female hurdlers competing after 2000 were heavier (p≤0.05). The analysis of time structure proves that modern female hurdlers cover the distance of 400 m faster in the first part (p≤0.01), and significantly decr ease the running speed in the final part of the run. The number of strides in Group B is significantly lower at the beginning of the run (p≤0.01), but increases significantly in its following part. Conclusion : The tactics of women’s 400m H run has changed after 2000. It affects indirectly changes in the training process.

Opis:
The study is devoted to the issue of criminal liability of a perpetrator suffering from conversion identity disorders. Therefore, its aim is to highlight the dilemmas arising from a split personality disorder in the context of the insanity of the perpetrator of a prohibited act. Based on the example of Kenneth Bianchi (case study), the difficulties related to the diagnosis of this disorder and its consequences in relation to criminal liability are shown. In turn, the analytical-dogmatic method is used to consider the issue related to the recognition of these disorders as a specific category of causes of the condition referred to in Article 31 § 1 of the Polish Criminal Code. Regardless of this, the study also presents an approach to this issue that differs from that previously presented in the literature. The conclusions drawn on this basis also allow for filling a certain gap in the Polish literature on criminal law, which is a lack of studies on the subject matter.

Opis:
This paper explores the interrelationships between religious attitudes, ethnic and linguistic identities, and geopolitical preferences in three geopolitical fault-line cities in Eastern Ukraine – Mariupol, Kharkiv, and Dnipro. The research is based on data taken from a survey and the associated descriptive statistics and correlation analysis. The findings suggest that the religious divide in Eastern Ukraine does not generate additional division but instead strengthens the existing divide, which is known to be formulated in terms of geopolitical as opposed to language or ethnicity-based categories, although language and ethnicity do have an influence on geopolitical preferences. Moreover, civic-national identity appears to be more relevant than ethnic-national identity to understanding the religious fault-line in Eastern Ukraine.

Opis:
Two types of composites, consisting of pure magnesium matrix reinforced with two commercially used carbon fibers, were systematically studied in this paper. The composites fabricated by the pressure infiltration method, were subjected to quasistatic and dynamic compression tests. Morphology of fiber strands was observed using scanning electron microscope (SEM). The application of carbon fibre reinforcement led to the stiffening of tested materials, resulting in the limitation of the possible compression to approx. 2.5%. The performed tests revealed the remarkable difference in compression strength of investigated compositions. The cause of that effect was that GRANOC fiber reinforced composite exhibited insufficient bond quality between the brittle fibers and the ductile matrix. T300 reinforced composite presented good connection between reinforcement and matrix resulting in increased mechanical properties. Investigated composites demonstrated higher mechanical strength during deformation at high strain rates. Microscopic observations also proved that the latter fibers with regular shape and dense packaging within the filaments are proper reinforcement when designing the lightweight composite material.

Opis:
The results of experimental and numerical analysis of the influence of the non-axisymmetric pulse shaper position on recorded wave signals in the split Hopkinson pressure bar experiment are presented. The paper focuses attention on the problem of wave signal disturbances caused by a bending wave resulting from non-axisymmetric pulse shaper positions and, moreover, different shaper thickness, striker impact velocities and Wheatstone bridge configurations. The obtained results of analyses indicate that the effect of the non-axisymmetric pulse shaper position may be neglected if deviation from the bar axis does not exceed 20%.
