Visualization of Particle Impact in Thermal Spray
Authors: Escure C. , Vardelle M. , Fauchais P. , Grimaud A.
Published: July 2021

Many studies have been devoted to particle flattening and resulting splat cooling. However, if recent models allow to compute the particle flattening time evolution, very few experiments in spraying conditions have been achieved to back such calculations. The aim of this paper is to describe an imaging device allowing the visualization of particle impacts on cold and hot surfaces. This technique makes it possible : • to investigate the "impact mode" : splashing, deposition or rebound, • to link the particle parameters at impact and the substrate parameters to the observed impact mode, • and therefore, to have a better understanding of coating formation. It consists in a controlled atmosphere chamber where is followed the impact of a single particle on a substrate which can be inclined. The particle parameters prior to its impact are measured : its surface temperature by fast (100 ns) two-color pyrometry, its velocity and diameter by Phase Doppler Anenometry (PDA). The particle image during flattening, splashing or rebounding is given by a fast camera (exposure/delay time 100ns to 1ms) with possible multi exposures. The camera is triggered by the PDA and/or the pyrometer. It is then possible to calculate for each molten particle its Sommerfeld parameter characterizing its impact mode (rebounding, deposition or splashing) when no solidification occurs during flattening. The substrate are made of stainless steel 304L rapidly covered by alumina splats resulting in a Ra~5-6µm. They are kept at 300°C, temperature at which splats are disk shaped on smooth substrate (Ra<0.05µm). The very preliminary results obtained show that unmolten or partially molten particles rebound in all directions but not elastically : the rebounding particle velocity is 3 to 5 times lower than that of the impacting one. For fully molten particles, splashing occurs in all cases even for low Sommerfeld numbers. It thus seems that the substrate roughness plays a key role in splashing.

Authors: Fukanuma H. , Huang Y.
Published: July 2021

This article examines the splat shape at off-normal angles in plasma spray and investigates the relationship between the splat elongation ratio and the spray angle on various spray materials and particle sizes. The applicability of the model to the experimental results is investigated. In this study, six powders of aluminum, copper, and nickel as metal spray materials and of alumina, titania, and zirconia as oxide materials were sprayed. It was observed that the model agreed well with the elongation ratio of the experimental results in the range between 90 and 30 degree. The model values were over-estimated than the practical results at spray angles less than 15 degree.

Authors: Lugscheider E. , Herbst-Dederichs C. , Reimann A.
Published: July 2021

Quasicrystalline phases improve many alloy properties such as thermomechanical stability, thermal and electrical conductivity, and tribological performance. High hardness, however, is accompanied by brittleness, an undesired property in many applications. Reduced brittleness can be achieved by embedding quasicrystalline phases in a more ductile material, forming a metal-matrix composite that retains some quasicrystalline properties. This study evaluates thermally sprayed coatings made from different compositions of such composites. The coatings assessed were produced by arc-wire, HVOF, and atmospheric plasma spraying using various forms of feed material, including blended, agglomerated, chemical encased, and attrition-milled powders and filled wires. The investigation involved metallurgical analysis, proving the existence of quasicrystal content and assessing the matrix phase, and tests showing how sliding wear is influenced by the composition of quasicrystalline phases.

Authors: Sordelet D.J. , Huang P. , Besser M.F. , Lepecheva E.
Published: July 2021

A brief feasibility study was performed to produce thermal spray coatings using gas atomized powders of Cu47Ti34-xZr11Ni8Six, where x=0 and 1. These alloys have previously been shown to be capable of forming metallic glasses having thick (1-2 cm) cross sections because they can be cooled from the melt at relatively low cooling rates (e.g., 100-102Ks-1). The properties of these metallic glasses include high strength, high elasticity and high fracture toughness. Amorphous plasma arc sprayed coatings were produced which were close in composition to the starting powders, and exhibited comparable glass transition and crystallization behavior. The amorphous structure of the as-sprayed coatings was used as a source for forming a range of partially devitrified and fully crystallized structures. The average hardness of the coatings increased from around 6 GPa to near 10 GPa as the degree of crystallization increased.

Authors: Shibata T. , Tahara H. , Yasui T. , Kagaya Y. , Yoshikawa T.
Published: July 2021

Electromagnetic acceleration plasma generators, which are called Magneto-Plasma-Dynamic (MPD) arcjet generators, can produce higher-velocity, higher-temperature and higher-density plasmas than those of conventional thermal plasma torches, because MPD arcjet plasma is efficiently accelerated by electromagnetic body forces in MW-class input power operation. These properties are effective for deposition of rigid coatings adhering strongly to substrate surfaces. In the present study, we newly developed an ablation type MPD arcjet generator for titanium nitride (TiN) reactive spray coatings. The coatings were deposited onto steel substrate. The phase structure and the composition of the coatings were analyzed by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD), and their Vickers hardness were measured. These analyses showed that the MPD spray process could successfully form dense and uniform titanium nitride coatings. The properties of the titanium nitride coatings were highly sensitive to the titanium cathode diameter and discharge current.

Published: July 2021

The metallic interior surfaces with cylindrical symmetry have been processed by knocking them with centrifuged balls. The first author has designed the used processing tool and it has been carried out under his instructions. There have been processed cast iron and carbon steel samples, using 80 different combinations for the process parameters: axial advance S, tangential rotation speed of the processed piece V, and the impact force F between the balls and the processed surface. Using the measured values of roughness Ra, Vickers microhardness HV and of the depths of cold-hardening h, we have achieved and used an optimizing computer program for the qualitative parameters of the cold-hardening process, i.e. Ra, HV and h. Also, we found optimal solutions for the processing regime. The study establishes the ability to increase the mechanical characteristics of the turned out metallic surfaces, thus taking out any further mechanical, thermal and/or chemical superficial processing. The results of the current study allow a correct choice of the processing regimes for different materials with similar bulk properties.

Authors: Simard S. , Arsenault B. , Laul K. , Dorfman M.R.
Published: July 2021

The HVOF technology is well known to provide a wide variety of coating materials having excellent performance characteristics under different aggressive conditions such as wear, erosion by impact of particle and corrosion. Carbides, as a family, constitute a big segment of materials used by the thermal spray industry. Although their material properties may be well known since they are often used in wear or corrosive-wear industrial applications, aqueous corrosion of such coatings are not well characterized. Moreover, thermal spray process technology being in constant evolution, past literature on these coatings may not be directly applicable as newer produced coatings have higher adhesive and cohesive strength. Recent technology allows a better control on density and oxides content that are important parameters to consider for corrosion applications. The success of a coating is related to judicious material selection for various applications. However, the choice of the starting materials for producing a coating is often difficult since there is a lack of data on the corrosion performance of thermal spray coatings. The present paper addresses the performance of various carbide HVOF coatings in terms of corrosion rate and degradation mode in two corrosive environments — HCl and HNO3. Behavior of the coatings is compared using bulk SS316 and SS316 HVOF coating as a benchmark.

Authors: Huang P.J. , Swab J.J. , Patel P.J. , Chu W.S.
Published: July 2021

The development of thermal barrier coatings (TBCs) for diesel engines has been driven by the potential improvements in engine power and fuel efficiency that TBCs represent. TBCs have been employed for many years to reduce corrosion of valves and pistons because of their high temperature durability and thermal insulative properties. There are research programs to improve TBCs wear resistance to allow for its use in tribologically intensive areas of the engine. This paper will present results from tribological tests of ceria stabilized zirconia (CeSZ). The CeSZ was applied by atmospheric plasma spray process. Various mechanical and thermal properties were measured including wear, coefficient of thermal expansion, thermal conductivity, and microhardness. The results show the potential use of CeSZ in wear sensitive applications in diesel applications. Keywords: Thermal Barrier Coating, Diesel Engine, Wear, Thermal Conductivity, and Thermal Expansion

The effect of high frequency pulse detonation (HFPD) and HVOF thermally sprayed WC-Co coatings on the high cycle fatigue (HCF) behavior of 2024-T4 aluminum was investigated. The fatigue life distributions of specimens in the polished and coated conditions are presented as a function of the probability of failure. The monotonic and cyclic deformation behaviors of the as-received and as-coated specimens were investigated. The conclusions show that, (i) the HFPD sprayed specimens exhibited slightly higher fatigue lives compared to the uncoated specimens, (ii) the HVOF sprayed specimens exhibited significantly higher fatigue lives compared to the uncoated specimens, and (iii) the as-coated specimen was cyclically stable.
Development and Performance Evaluation of Thick Air Plasma Sprayed Thermal Barrier Coatings
Authors: Mutasim Z.Z. , Nava Y.L.
Published: July 2021

Air plasma sprayed thermal barrier coatings have been widely used to reduce metal wall temperatures of industrial gas turbine combustor liners. Thermal barrier coatings provide thermal gradients, with the goal of reducing the liner wall temperature to acceptable levels as a result of their low thermal conductivity. A typical thermal barrier coating consists of a 0.1-0.2 mm MCrAlY bond coating and a 0.25-0.35 mm thick 8 wt.% yttria stabilized zirconia ceramic top coating. A method to increase thermal barrier coating effectiveness is the application of thicker ceramic coatings. Development and performance testing of 0.5-0.8 mm thick ceramic coatings are discussed in this paper. Cyclic oxidation tests that simulate industrial gas turbine environments were conducted. Thermal barrier coating degradation-mechanisms were determined from microstructural evaluation of thermally exposed samples.

Authors: Grosdidier T. , Liao H.L. , Tidu A.
Published: July 2021

FeAl iron-aluminide based materials with the ordered B2 structure are excellent candidates for use in high temperature applications because of the combination of good mechanical properties, low density, low cost and availability of raw materials, and improved oxidation resistance. The aim of this article is to produce an ultra-fine grained FeAl coating by HVOF thermal spraying of milled powders and characterize the fine scale features of its microstructure. Comparison is made with a more conventional coating obtained by projection of powders obtained by atomization. Starting powders and coatings were investigated using X-ray diffraction and transmission electron microscopy. It was observed that the coating obtained from milled powders had a microstructure essentially characterised by a nanometer grain size and the presence of a disordered FeAl phase.

REARRANGEMENT OF THE CONFORMATIONAL STRUCTURE OF POLYAMPHOLYTES ON THE SURFACE OF A METAL NANOWIRE IN A TRANSVERSE MICROWAVE ELECTRIC FIELD
Authors:   Center of Laser and Informational Biophysics, Orenburg State University, Orenburg, Russia, Kruchinin N. Yu.
Published: July 2021

Molecular dynamics has been employed to study the rearrangement of the conformational structure of polyampholytes adsorbed on the surface of a gold nanowire with a periodic change in time of its polarity in the transverse direction at an ultrahigh frequency. The radial distributions of the atomic density of the polypeptide and its angular distributions on the nanowire surface have been calculated. At high temperatures, temporary fluctuations in the conformational structure of the adsorbed polyampholyte polypeptide were observed. In this case, for half the period of the nanowire polarity change, the macrochain conformation changed from dense enveloping of the nanowire to an elongated conformational structure along the dipole moment of the nanowire. At low temperature and the nanowire dipole moment, the swelling of the fringe of the adsorbed polyampholyte was observed with a displacement of most of its links to one side with respect to the plane perpendicular to the direction of the nanowire dipole moment and passing through its axis. At low temperature and high values of the nanowire dipole moment, the polyampholyte polypeptide was desorbed from the nanowire surface. An analytical model of conformational rearrangements of a polyampholyte Gaussian chain in the form of an external field perturbation theory is presented.

Authors:   Razuvaev institute of organometallic chemistry, Russian Academy of sciences, Nizhny Novgorod, Russia, Shishulin A.V.
Published: July 2021

In this paper, we have shown how the presence of pores and pore morphology influence on magnetic phase transition temperatures in mesoporous ferromagnetic materials. Model calculations have demonstrated the possibility to obtain macroscopic mesoporous samples with notably reduced Curie temperatures which is also further depressed in the case the pore morphology is more complicated. The results have been obtained on the basis of the experimentally verified correlation between the Curie temperature and cohesive energy of the material and illustrated using the examples of pure mesoporous iron, nickel and cobalt while pore morphology has been determined by the methods of fractal geometry. Several practical applications of mesoporous materials with tuned values of the Curie temperature have also been discussed in the final section.
COMPARATIVE STUDY OF THE EFFECT OF FLAME RETARDANTS ON THE IGNITION TEMPERATURE OF EPOXY COMPOSITES
Authors:   National Research Tomsk Polytechnic University, Tomsk, Russia, Amelkovich Yu.A.
Published: July 2021

The disadvantage of polymeric materials, including epoxy resins, is their increased fire hazard. Reducing the flammability of polymeric materials is a serious problem that needs to be addressed. One of the ways to reduce the flammability of polymers is the introduction of special additives into the polymer matrix with flame retarding properties, which leads to a change in the nature of the processes occurring during the combustion of the polymer, or to blocking the combustion process with non-combustible or inhibiting substances. In this work, aluminum trihydroxide, melamine polyphosphate, and melamine poly(magnesium phosphate) were used as flame retardants to enhance the flame-resistant properties of epoxy resin. The filler loading in the epoxy composites was 10 wt. %. The experimental studies have been carried out to determine the ignition temperature of the produced epoxy composites. The data obtained were compared with the ignition temperature of a control sample of epoxy resin without filler. The results indicated that the incorporation of all the flame retardants studied resulted in an increase in the ignition temperature. The ignition temperature of the samples filled with melamine polyphosphate and melamine poly(magnesium phosphate) increased by 28 and 11 °C, respectively. However, the best result was obtained for a sample filled with aluminum trihydroxide: the ignition temperature of this sample was 40 °C higher than that of the unfilled epoxy resin.
SCALE-INVARIANT AND WAVE NATURE OF THE HUBBLE PARAMETER
Authors:   al-Farabi Kazakh National University, Almaty, Kazakhstan, Zhanabaev Z.Zh.
Published: July 2021

The value of the global Hubble parameter corresponding to astrophysical observations was determined theoretically without using ʌСDM models. A nonlinear fractal model of the connection between the distance to the observed galaxy and its coordinate is proposed. Distance is defined as a fractal measure, the measurement scale of which, in contrast to the known fractal models, corresponds to the deviation of the desired measure itself from its fixed value (radius of zero gravity), relative to which the scale invariance is assumed. We used the dimension of our proposed specific anisotropic fractal, which simulates the increase in the distance to the observation point. It is shown that this dimension is also the maximum dimension of the strange attractor of the phase portrait of the equation of gravitational waves and sets of galaxies from different catalogs.

In this article, the authors note the current state of the education system and, in general, personnel training in Kazakhstan, its insignificant isolation from the real needs of the socio-economic system, insufficient relationship with the scientific field of activity. However, on the basis of the differentiation presented examples of successful implementation of state programs of education development in the Republic of Kazakhstan aimed at improving the competitiveness of education and development of human capital through ensuring access to quality education for sustainable economic development, and also noted that the global changes in economic and political life of the country will lead to the emergence of new socially significant landmarks in the educational system. Based on the use of integration from the point of view of the effectiveness of the existing agreements on the Eurasian Economic Union, a number of problems that need to be solved in ensuring the quality of human capital are identified. According to the authors, this leads, in turn, to the importance of measuring potential risks, as well as to the connection with qualitative and quantitative factors of the development of the education system and the training system

The article examines several aspects of the quality of educational services. The process of providing such services is examined, the problems in the field of teaching physics and mathematics are identified and the ways of problem resolution in the credit learning system are proposed. The introduction of credit learning technology allows for stimulation of students’ learning activity and an increase in their motivation and the level of academic mobility. The ways of increasing the motivational activity of the teacher as another key figure in the educational process are identified. The current remuneration system for university teachers in Kazakhstan accounts for work experience and the position held and includes additional payments for an academic degree but does not stimulate teachers for continuous additional training. On the other hand, the salary volume does not contribute to the high social prestige of this profession, which is complex and requires genuine pedagogical skills. The quality of teaching staff is associated with the quality of education acquired by students. In the context of the credit rating system, it is not only students who earn credits, but also teachers who should substantiate and improve their qualifications measured by their rating.

The article examines the degree of acmeological competence formation among the future foreign languages teachers, since, according to scientists’ research in this field, acmeological competence plays an important role in the formation of a future teacher’s personal and professional attributes, as well as in his selfdevelopment throughout his career. The need for the trilingual education policy, where such personal qualities as self-development, self-realization, and self-improvement important for implementation, has been revealed as well. Such concept definition as «acmeological competence» has been defined, and the level of future teachers’ knowledge concerning this concept has been studied. The study resulted in the following conclusions: most of the future teachers are able to independently solve problems related to their professional activity, which can have a positive effect on their competencies; future foreign languages teachers attach particular importance to the transmission of knowledge, skills, as well as modern teaching methods, whereas the knowledge concerning the personal and professional advancement and motivation for self-development are relegated to the background; the majority of future teachers have no idea of the acmeological competence essence and make no effort on bringing out the best in themselves. Thus, the conclusion says that the future foreign languages teachers are not sufficiently informed about the «acmelogical competence» concept and the importance of its study. Hence, the degree of acmeological competence formation among future foreign languages teachers leaves much to be desired.

The city of Ternopil is one of the regional centers of Ukraine, the rate of landscaping which is one of the highest. Among the plantations of the city with a large area (22,0 hectares) stands out the park of Taras Shevchenko, located on the banks of the Ternopil pond. V.M. Chernyak, V.O. Burma, I.O. Pyatkivsky, R.B. Dudyn, P.P. Tsaryk, S.M. Pidkhovna and others studied the flora of the city of Ternopil and the region. The dendroflora of the park includes 55 taxa of trees, shrubs and vines, which belong to 38 genera and 24 families. The most numerous in terms of number of representatives are the families Rosaceae and Pinaceae. The total number of woody plants is 1836 specimens. The park is significantly dominated by deciduous trees and shrubs (82%). In general, trees make up 77%, of which conifers – 12,4%. All woody plants of the park are phanerophytes, and mesophanerophytes dominate – 62%. In relation to light, light-loving species predominate (68%). 51% of plants are cold-resistant and only 19% are heat-loving. Most of the park's plants are resistant to environmental pollution (only 10% are not gas-resistant). The results of the study of plants in relation to fertility and soil moisture indicate favorable conditions for their growth and development, as most of them show medium and high demands on habitat conditions: 69% are meso- and mesohygrophytes and 56% – megatrophs. Based on the sanitary assessment of the plantations, it was found that about 8,5% of the park's plants have various damages: frost cracks, core rot, coppice, hollows. 8 dead trees were found, 32 specimens need sanitary pruning. 17 plants are recommended for removal for various reasons.
WATER BALANCE AND ECOLOGICAL CONDITIONS OF THE RYBINSK RESERVOIR IN THE EXTREMELY HIGH-WATER YEAR OF 2017
Authors: Litvinov A.
Published: July 2021

This study analyzes the inflow, runoff and water level of the Rybinsk Reservoir during the extremely highwater year of 2017. It was the second-highest on record high-water year in the reservoir basin during the whole period of the reservoir operation. The total annual inflow to the reservoir significantly exceeded its long-term average and amounted to 52,148 km3. Such an increase in the inflow is due to rising air temperatures in winter time under the increasing influence of global warming and high rainfall. To characterize ecological conditions in the reservoir we use data on its water balance, mean ten-day period water temperature in May-October provided by Yaroslavl Center for Hydrometeorology and Environmental Monitoring and materials from six hydrological and hydrobiological expeditions conducted by researchers from the Institute for Biology of Inland Waters RAS (IBIW RAS) in May-October, 2017. During the expeditions to the reservoir, integrated hydrological, hydrochemical and hydrobiological investigations were conducted at standard stations. These studies have been carried out by IBIW researchers since 1962 to monitor the dynamics of ecological conditions of the waterbody.

Przestępstwo poszukiwania zabytków ruchomych bez pozwolenia lub wbrew jego warunkom – analiza prawnokarna.
Authors: Janikowski Jarosław
Published: July 2021

Poszukiwanie zabytków to zjawisko dostrzegalne, lecz w dużej mierze błędnie interpretowane z perspektywy prawnej. Brak wymaganego prawem pozwolenia lub poszukiwanie wbrew warunkom takiego pozwolenia jest przestępstwem w myśl przepisu z art. 109c ustawy o ochronie zabytków i opiece nad zabytkami. Jak pokazują dane statystyczne większość eksploratorów nie zdaje sobie sprawy z takiego wymogu, co w rezultacie generuje wysoki odsetek przestępczości niewykrytej. Ważne jest więc dla podnoszenia świadomości społecznej, by kwestie z tym problemem związane podnosić w jak najszerszym spectrum naukowej eksploracji.
„Inny podobnie niebezpieczny przedmiot” jako instrumenta sceleris w świetle przepisów części szczególnej kodeksu karnego
Authors: Szajna Arkadiusz Paweł
Published: July 2021

Celem niniejszej pracy jest przedstawienie czym powinny odznaczać się instrumenta sceleris aby w świetle art. 159, 223 § 1, 280 § 2, 345 § 3 k.k. można było zaliczyć je do kategorii „innych podobnie niebezpiecznych przedmiotów”. Omówiono trzy koncepcje prezentowane w doktrynie i judykaturze dot. sposobu dokonywania oceny „niebezpieczności” w stosunku do danego przedmiotu, ze wskazaniem w formie apelu do środowiska prawniczego - zdaniem autora - tej najwłaściwszej. Na końcu pracy zaprezentowano przegląd orzecznictwa w zakresie jakim przyznano (bądź nie) danemu przedmiotowi przymiot „innego podobnie niebezpiecznego”.
Gdzie kończy się norma (…) a zaczyna patologia . Kilka uwag o niepoczytalności na gruncie wielomodelowego definiowania „zdrowia psychicznego” w świetle rozważań Georga E. Vaillant’a
Authors: Żywucka - Kozłowska Elżbieta Agata
Published: July 2021

Powszechne rozumienie normalności sprowadza się do tego, że  nic nie jest odmienne, inne i mieści się w ramach zwyczajności. Patologia w tym układzie znajduje się poza obszarem owej normalności, utożsamianej ze zwyczajnością. W niniejszym opracowaniu podjęto próbę ustalenia determinantów patologii jak i normy w perspektywie prawa karnego materialnego, psychologii jak i psychiatrii.  Wydawać się może, że w tym obszarze przedstawiono już wszystkie argumenty „ za i przeciw”, oparte na przepisach prawa jak i poglądach doktryny. Pomiędzy jednym a drugim pojęciem ( poczytalności i niepoczytalności jak  też  normy i patologii) , nie ma próżni. Są bowiem stany , których istotą jest brak stałości w szerokim tego określenia rozumieniu, jak i też stany takie, które z jednej strony mieszczą się w obszarze patologii z punktu widzenia psychiatrii i psychologii, zaś w perspektywie prawa nie stanowią przesłanki niepoczytalności czy poczytalności ograniczonej
Interes spółki kapitałowej a przestępstwo karalnej niegospodarności
Authors: Oczkowski Tomasz Edward
Published: July 2021

Artykuł dotyczy złożonych relacji między prawem karnym a prawem handlowym w aspekcie karnej ochrony interesów spółki kapitałowej. Jednym z kluczowych problemów interpretacyjnych jaki można tu dostrzec, to kwestia znaczenia  interesu spółki.  I dlatego zasadne jest dokonanie analizy, jak rozumie się pojęcie interesu spółki kapitałowej w prawie handlowym i czy wykładnia ta ma znaczenie przy wykładni znamion karalnej niegospodarności opisanej w art. 296  polskiego kodeksu karnego. W tym przecież przepisie interes majątkowy spółki jest chronionym dobrem. Dodatkowo dokona się analizy autonomiczności prawa karnego przy wykładni przepisów karnych ściśle powiązanych z przepisami z innych gałęzi prawa. Zostanie wykazane, że wykładnia interesu spółki w prawie handlowym jest wiążąca w procesie wykładni znamion przestępstwa niegospodarności. Natomiast z uwagi na złożoną strukturę przestępstwa, wykonanie bezprawnych uchwał wspólników nie musi oznaczać dokonania przestępstwa niegospodarności.
Kryminologiczne i ekonomiczne aspekty bezdomności
Authors: Truskolaska Emilia Magdalena , Truskolaski Tadeusz
Published: July 2021

Celem artykułu jest zbadanie zjawiska bezdomności, prawnych aspektów jego funkcjonowania oraz ekonomicznych skutków ponoszonych przez Miasto Białystok. Autorzy podjęli poniższą tematykę gdyż jest ona tematem aktualnym i wymagającym bieżącej analizy. Po zmianie ustrojowej jaka dokonała się w Polsce w 1989 roku wiele problemów społecznych na nowo ujrzało światło dzienne. Zjawisko bezdomności jest jednym z tych, które eskalowało i sprawiło, że zaczęto poszukiwać nowych narzędzi do jego zapobiegania i rozwiązania. Po dziś budzi ono wiele wątpliwości wśród badaczy ponieważ skala i dynamika problemu jest nieustannie zmienna. Bezdomność jest przejawem wykluczenia społecznego z najważniejszych sfer życia. Poniższe opracowanie przedstawia aspekty prawne oraz finansowe bezdomności na przykładzie miasta Białystok. Wieloaspektowa diagnoza stanowi podstawę do efektywnego przeciwdziałania bezdomności i precyzyjnego rozpoznania problemu.
Prowadzenie postępowania dowodowego w czasie nieobecności oskarżonego w świetle orzecznictwa strasburskiego i nowych regulacji Kodeksu postępowania karnego zawartych w art. 378a
Authors: Siczek Katarzyna Justyna
Published: July 2021

Pomimo, że prawo oskarżonego do udziału w czynnościach postępowania dowodowego zostało zapisane w k.p.k. jako reguła kształtująca przebieg tego postępowania, kolejne nowelizacje procedury karnej rozszerzają katalog sytuacji, w których to prawo może podlegać ograniczeniu. Wynika to m.in. z dążenia do zapewnienia sprawności postępowania i zapobiegania przewlekłości postępowań karnych. Ostatnim z takich zapisów, wprowadzonych z dniem 5.10.2019 r. jest art. 378 a k.p.k. przewidujący możliwość prowadzenia postepowania dowodowego pod nieobecność oskarżonego lub jego obrońcy, również gdyby była to nieobecność usprawiedliwiona. Omawiany przepis pozwala na daleko idące odstępstwa od reguły zapisanej w art. 390 § 1 k.p.k..  To z kolei  rodzi pytanie o jego zgodność ze standardami strasburskimi wynikającymi z orzeczeń wydawanych przez ETPC na gruncie art. 6 EKPC, aktu prawnego ratyfikowanego przez nasze państwo, który powinien być respektowany w procesie stanowienia i stosowania prawa. Analiza nowej regulacji, poczyniona w świetle standardów wynikających z orzecznictwa strasburskiego pozwala na  spostrzeżenie, że omawiany przepis art. 378 a k.p.k. wymaga ustawowej korekty, w kierunku zagwarantowania osobom oskarżonym realnego prawa do obrony materialnej i formalnej, jak też równości stron. Zostały one szczegółowo omówione w niniejszym opracowaniu.  Po dokonaniu powyższych zmian, w sposób uwzględniający poszanowanie strasburskich standardów rzetelnego procesu, może on w szczególności zapobiec utracie możliwości bezpośredniego zbadania dowodu przez skład orzekający na rozprawie głównej.
Dowód poszlakowy a postępowania karne dotyczące wyłudzeń podatku VAT
Authors: Komar-Nalepa Aleksandra
Published: July 2021

Celem niniejszego artykułu jest zdefiniowanie pojęcia dowodu poszlakowego oraz przedstawienie jego roli w postępowaniach karnych w sprawach o wyłudzenia podatku VAT. Autorka przedstawia różnicę pomiędzy dowodem poszlakowym a pojedynczą poszlaką, opisuje proces budowy dowodu poszlakowego a następnie odnosi te rozważania do procesów karnych dotyczących wyłudzeń podatku VAT, wskazując że bardzo często wymagają one skrupulatnej budowy dowodu poszlakowego, w celu weryfikacji prawdziwości wyjaśnień składanych przez wzajemnie się obciążających współoskarżonych.
