Cossacks Identity Problem in the Context of Social and Cultural Integration of the Russian Population in the Modern Conditions
Authors: Капица  , Kapitsa G. , Кащенко  , Kashchenko T.
Published: March 2016

The authors aim to define the foundations of identity of

Cossacks as a part of the multi-layered identity in the Russian

Federation. Two concepts are considered: the ambivalence of Cossacks

and the concept of cultural core of self-determination of Cossacks.

The paper emphasizes the special role of the Cossacks in the Russian

socio-cultural situation in view of the fact that the Cossack values

and behavioral complex is still relevant today, it fits well with the

modern Russian reality. Cossacks today are a reliable stronghold of

the healthy statehood.

Most Coarctations, Recoarctations, and Coarctation-Related Aneurysms Should Be Treated Endovascularly
Authors: Galiñanes Edgar , Krajcer Zvonimir
Published: March 2016

Based on a Presentation at the 2013 VEITH Symposium, November 19-23, 2013 (New York, NY, USA)

For patients with coarctation of the aorta (CoA), surgical intervention results in an overall survival rate nearly twice that of medical management. Therefore, surgical correction of CoA has traditionally been warranted in the majority of patients, even though open repair entails its own complications. With the advent of endovascular technology, many interventionalists hoped that this approach would decrease the complications associated with open surgical repair of CoA. Nevertheless, there is still an ongoing debate about the merits of traditional open surgery versus endovascular therapy. In this review, we discuss the role of these two approaches for the management of CoA, recoarctation, and coarctation-related aneurysms.
Open Stented Grafts for Frozen Elephant Trunk Technique: Technical Aspects and Current Outcomes
Authors: Ma Wei-Guo , Zheng Jun , Sun Li-Zhong , Elefteriades John
Published: March 2016

With growing experience in patients with aneurysms and dissections in the arch and proximal descending aorta, the frozen elephant trunk (FET) technique has been shown to be safe and effective, and has achieved favorable short to mid-term outcomes. As the FET technique is gaining wider acceptance, there is a growing need for versatile, technically simple, and highly durable open stented grafts involving less complicated deployment mechanisms enabling use in various indications. This paper gives a brief review on the technical aspects and clinical outcomes of currently available open stented grafts used in the FET technique, including the E-vita Open Plus, Thoraflex Hybrid, Cronus, and J Graft. While none of these grafts can claim to be an ideal device, technology continues to improve towards this goal. As newer devices and systems are developed, more widespread use of the FET technique can be expected; such progress promises to improve the clinical outcomes and quality of life for patients with complex aortic diseases.
Two-Stage Procedure for Infected Aortic Graft Pseudoaneurysm
Authors: von Aspern Konstantin , Etz Christian , Mohr Friedrich , Battellini Roberto
Published: March 2016

Prosthetic graft infections with mediastinitis following aortic surgery are rare, yet represent grave complications yielding high morbidity and mortality. We present the case of a 57-year-old female patient with past history of emergent surgery for iatrogenic Type A dissection treated by supracoronary ascending aortic replacement. Four months after the initial surgery, a sternal fistula had formed and due to severe bleeding emergent reoperation was required. Imaging and pathology on admission revealed an infected pseudoaneurysm at the distal aortic prosthesis and mediastinitis with methicillin-resistant Staphylococcus aureus. Rescue surgery was performed by means of a two-stage approach, with extensive debridement, graft replacement and continuous antiseptic lavage in a first step and an omental wrapping of the new prosthesis in a second stage 24 hours later. During 10 years of follow-up, no recurrent infection occurred. The operative approach and general considerations for management of infected pseudoaneurysms are discussed.
Acute Type B Aortic Pathology Mimicking Acute Type A Intramural Hematoma with Organ Malperfusion
Authors: Levy Eli , Korach Amit , Rubinstein Chen , Gilon Dan , Shapira Oz
Published: March 2016

The management of acute Stanford Type A intramural hematoma (IMH) of the aorta remains controversial. Most surgeons advocate emergency surgery in a manner similar to frank acute Type A dissection. Others recommend a conservative approach to this distinct clinicopathological entity. We describe a case of acute aortic pathology initially diagnosed as Type A IMH with organ malperfusion, subsequently identified as acute Type B pathology with retrograde and antegrade extension. An endovascular approach was successfully used to exclude the site of origin.

CQC inspections: is the service effective and caring?
Authors: Ellis Peter , Abbott Jane
Published: March 2016

As part of a series looking at Care Quality Commission (CQC) inspections, Peter Ellis and Jane Abbott consider the two key questions: is the service effective and caring, and what is needed to meet these requirements?. They look at the various areas that come within these categories, such as are staff aware of the needs of people with dementia, and does the service recognise diversity in all its forms?
Bidirectional Data Collaborations in Distributed Research
Authors: Haynes Kevin , Selvam Nandini , Cziraky Mark J.
Published: March 2016

Introduction: The need for collaborations with bidirectional data exchange within
and across distributed research networks has increased.Currently Existing
Activities: This commentary will present currently publically available activities
including the Sentinel Initiative, the Patient-Centered Outcomes Research Network
(PCORnet), and the NIH Research Collaboratory.Current Technical and Governance
Challenges: Even with the advances made in this arena, several technical and governance
challenges remain including the evolution of clinically rich data sources and modes of
care, availability of longitudinal data resources through data linkage, and the
processes to share data and link data resources while ensuring privacy and proprietary
control of data.Perspective: These activities will require enhanced levels of trust
between entities involved in the delivery of healthcare (Trust 2.0) in addition to the
trust health plans and health systems have with patients (Trust 1.0). Recent public
funding announcements and public access to data resources will likely improve the
landscape of bidirectional data collaborations in distributed research.
Reglas, principios y derrotabilidad
Authors: Bäcker Carsten
Published: March 2016

La distinción entre reglas y principios presupone un criterio que no sólo permite identificarlos como tales, sino también subrayar sus diferencias. En este ensayo la noción de derrotabilidad cumplirá el papel de tal criterio. La derrotabilidad debe ser entendida como la capacidad de admitir excepciones. Las reglas, en general, poseen excepciones. Estas excepciones no pueden ser enumeradas de forma conclusiva, por cuanto las circunstancias que darán origen a casos futuros son desconocidas. En consecuencia, las reglas jurídicas siempre podrán admitir excepciones, esto es, son derrotables. Por el contrario, los principios como mandatos de optimización no admiten excepciones en ese sentido. Más bien, las circunstancias de casos futuros junto a otras condiciones, por ejemplo, la colisión entre principios, se encuentra ya implícita en el concepto de optimización y es, por tanto, esencial a la aplicación del mismo principio. Esto significa que la optimización se encuentra necesariamente relacionada con todas las circunstancias dadas. Por tanto, para aplicar un principio es preciso optimizar —y de esa forma considerar necesariamente todas las circunstancias dadas—. De ese modo, no puede surgir una excepción en la aplicación de un principio. Los principios, en otras palabras, no son derrotables. El ensayo concluye con la explicación acerca del carácter prima facie de las reglas y los principios, apelando nuevamente a la noción de derrotabilidad junto a la propuesta de una triple distinción conceptual que ofrece alguna claridad adicional en lo que al concepto de principio se refiere.
Una nueva visita a la concepción expresiva
Authors: Calzetta Alejandro Daniel , Sardo Alessio
Published: March 2016

En 1981, Carlos Alchourrón y Eugenio Bulygin publicaron «The Expressive Conception of Norms», un trabajo relativo a dos posibles concepciones de las normas: la concepción hilética y la concepción expresiva. El desarrollo de la concepción expresiva presentado en aquel artículo dio origen a un profundo debate entre los mismos Alchourrón y Bulygin y Ota Weinberger, acerca de la ontología de las normas y la viabilidad de la propia concepción expresivista. Nuestro trabajo intenta ir un poco más lejos en la crítica de Weinberger a esta concepción (basándonos, en parte, en algunos trabajos sobre el tema realizados por Alf Ross), y ver hasta qué punto esta variante del expresivismo normativo falla, sin por ello olvidar que la misma es el punto de partida para una concepción expresivista de las normas más desarrollada. Al final del trabajo, se harán algunas consideraciones acerca de la concepción hilética.
En defensa de la concepción expresiva de las normas
Authors: Kristan Andrej
Published: March 2016

Frente a tres décadas de objeciones a la concepción expresiva de las normas, tal como fue presentada por Alchourrón y Bulygin, el autor de este trabajo pretende demostrar, primero, que un expresivista que asumiera la propuesta de los dos maestros argentinos puede dar cuenta de los estados de cosas facultativos sin introducir incoherencias dentro del sistema normativo; segundo, que también puede describir con éxito el contenido proposicional de una metarregla sin dar contenido semántico al indicador de fuerza (normativa) de la regla-objeto; y tercero, que puede dar cuenta de una clausura permisiva aun cuando niegue la autonomía conceptual de los actos de permisión. A partir de estas demostraciones, el trabajo cierra sugiriendo una solución para una adecuada representación expresivista de las normas condicionales.
The Concept of Law. Cincuenta años
Authors: Redondo María Cristina
Published: March 2016

En este trabajo se discuten dos interpretaciones usuales hoy día de la obra de Hart y se trata de evaluar su alcance para la comprensión coherente de este autor y para la teoría positivista del derecho. La primera es la postura que interpreta que el objetivo pretendido por Hart en El concepto de derecho puede verse (a pesar de su orientación analítica y antimetafísica) como un intento de desentrañar la verdadera esencia o naturaleza del derecho, esto es, las características esenciales del concepto que se refiere a él. ¿Es coherente esta interpretación con el compromiso positivista con el empirismo? La segunda cuestión tiene que ver con la relación entre derecho y moral: a pesar de la explícita defensa hartiana de un concepto positivista de derecho, actualmente se afirma que Hart no rechaza la tesis de la conexión necesaria entre derecho y moral. ¿Es posible conciliar esta tesis con el concepto y el método positivistas que Hart supuestamente asume?.
Algunos argumentos a favor de una ciencia jurídica interpretativa
Authors: Schiavello Aldo
Published: March 2016

La ciencia jurídica de matriz iuspositivista establece un ligamen preciso entre el derecho y el lenguaje. Según esta perspectiva, el derecho es el discurso del legislador y la ciencia jurídica no es otra cosa que un discurso sobre un discurso: un metalenguaje descriptivo del lenguaje prescriptivo del legislador. Esta concepción del derecho y este modelo de ciencia jurídica están en crisis desde hace algunas décadas. En mi artículo presento cuatro argumentos dirigidos a señalar los límites de esta aproximación al derecho: el argumento epistemológico, el argumento del pluralismo epistemológico, el argumento del giro interpretativo y, finalmente, el argumento funcionalista. Estos argumentos no están todos al mismo nivel y no tienen todos la misma fuerza. Algunos proporcionan sólo una explicación de por qué la ortodoxia iusanalítica sobre la ciencia jurídica esté siendo atacada. Otros tienen la pretensión de identificar algunos límites estructurales y conceptuales de este modelo.
¿Deben los filósofos morales aprender de los juristas?
Authors: Seleme Hugo
Published: March 2016

Existen diferentes servicios que los filósofos morales pueden prestarles a los juristas. Los mismos son variados y ha sido explicitados en diferentes trabajos. La hipótesis de este trabajo es que la relación inversa también es cierta. Existen tres maneras viciadas de hacer filosofía moral que los juristas pueden ayudar a combatir. La primera consiste en la obsesión metaética fundada en un sesgo escéptico hacia cualquier reflexión sustantiva. La segunda es el diletantismo activista de aquellos que sin ninguna preparación teórica se dedican a hablar de problemas morales y políticos. La tercera consiste en una forma de reflexión filosófica que en su afán de encontrar los principios supremos ha perdido todo contacto con la experiencia moral humana. El contacto con los juristas puede ayudar a combatir estos vicios, prestando de este modo la reflexión jurídica un servicio a la Filosofía Moral.

Об одном классе векторных полей
Authors: Исламов Галимзян Газизович , Islamov Galimzian Gazizovich
Published: March 2016

Показано, что простой постулат «Поле смещений вакуума есть нормированное электрическое поле» эквивалентен трeхпараметрическому представлению поля смещения вакуума:
$$
u(x;t) = P(x) \cos k(x)t + Q(x) \sin k(x)t.
$$
Здесь $t$ - время; $k(x)$ - частота колебаний в точке $x$ трeхмерного евклидова пространства;
$P(x)$, $Q(x)$ - ортонормированная пара стационарных векторных полей; $(k,P, Q)$ - список параметров смещения.
При этом нормировочный коэффициент $k^2(x)$ имеет размерность $T^{-2}$. Он обеспечивает единичную норму смещения $u(x;t)$ при любом $t$.
Скорость поля смещений
$$
v(x;t) = \frac{\partial u(x;t)}{\partial t} = k(x)(Q(x) \cos k(x)t - P(x) \sin k(x)t).
$$
Напряжeнность электрического поля, отвечающего указанному распределению поля смещения вакуума, даeтся формулой
$$
E(x;t) = -\frac{\partial v(x;t)}{\partial t}
= k^2(x)u(x;t).
$$
При этом магнитная индукция
$$
B(x;t) = \mathop{\mathrm{rot }} v(x;t).
$$
Эти конструкции применяются при отыскании локальных и глобальных решений системы уравнений Максвелла, описывающих динамику электромагнитных полей.
Задача Дирихле для уравнения смешанного типа с двумя линиями
перехода в прямоугольной области

При доказательстве единственности используется полнота в пространстве $L_2$ системы, биортогонально сопряженной с системой собственных функций соответствующей одномерной задачи. При построении решения в виде суммы ряда по биортогональной системе функций возникает проблема малых знаменателей. Получены оценки об отделимости знаменателей от нуля.
Ширина распада бозона Хиггса на два фотона в однопетлевом приближении
с учетом СР-нарушения в НМССМ
Authors: Гурская Альбина Валентиновна , Gurskaya Al'bina Valentinovna
Published: March 2016

В статье рассматривается проблема расширения стандартной модели физики элементарных частиц. Основное внимание уделено неминимальной суперсимметричной модели. На сегодняшний день еe рассмотрение является наиболее приемлемым по сравнению с другими разрабатываемыми суперсимметричными теориями. Мы также рассматриваем нарушение СР-инвариантности в секторе Хиггса. При нахождении физических состояний бозонов Хиггса мы находим локальный минимум потенциала Хиггса. Эту процедуру необходимо выполнить для того, чтобы получить стабильное состояние вакуума. Далее произведены расчеты ширины распада бозона Хиггса на два фотона. Мы используем метод квантово-полевой теории возмущений совместно с фейнмановским диаграммным подходом. Результаты расчeтов представлены графически. Показано влияние СР-нарушающей фазы на величину ширины распада. Также приведены зависимости масс бозонов Хиггса от фазы СР-нарушения в древесном приближении. Некоторые параметры модели не определены на эксперименте, а заключены в некотором диапазоне значений, что дает возможность рассматривать различные сценарии нескольких бозонов Хиггса. В частности, в случае СР-нарушения возможно существование бозона Хиггса с массой меньше 125 ГэВ. Это объясняется отсутствием определенного СР-состояния этой частицы.
О решении уравнения свертки с суммарно-разностным ядром
Authors: Барсегян Ани Гарниковна , Barseghyan Ani Garnikovna
Published: March 2016

В работе рассматриваются интегральные уравнения второго рода с суммарно-разностным ядром.
Такими уравнениями описывается ряд физических процессов, происходящих в среде с отражающей границей.
Отмечаются трудности, возникающие при их приближенном решении методами гармонического анализа, механических квадратур и др.
Для численно-аналитического решения рассматриваемого уравнения в неособом случае развивается метод усреднения ядра. Метод усреднения ядра, имеющий некоторую общность с методом полос, ранее был применен в одной (совместной) работе автора для решения интегрального уравнения Винера-Хопфа. Этот метод сводит исходное уравнение к линейной алгебраической системе с теплиц-плюс-ганкелевой матрицей. Получена оценка для погрешности в различных функциональных пространствах. В случае большой размерности полученной алгебраической системы его решение известными методами линейной алгебры может оказаться весьма затруднительным. В предлагаемом методе решения данной системы существенным образом используется сверточная структура этой системы. При этом сочетаются метод нелинейных уравнений факторизации и дискретный аналог одного специального факторизационного метода, развитого ранее автором для интегральных уравнений.
Обратная задача для нелинейного интегро-дифференциального уравнения Фредгольма
четвертого порядка с вырожденным ядром
Authors: Юлдашев Турсун Камалдинович , Yuldashev Tursun Kamaldinivich
Published: March 2016

Рассмотрены вопросы об однозначной разрешимости обратной задачи для одного нелинейного интегро-дифференциального уравнения типа Фредгольма в частных производных четвертого порядка с вырожденным ядром. Развит метод вырожденного ядра для случая обратной задачи для рассматриваемого интегро-дифференциального уравнения типа Фредгольма в частных производных четвертого порядка. С помощью обозначения интегро-дифференциальное уравнение типа Фредгольма сведено к системе интегральных уравнений. Система интегральных уравнений путем дифференцирования сведена к системе дифференциальных уравнений. При выполнении определенного условия система дифференциальных уравнений заменена системой алгебраических уравнений. При регулярных значениях спектрального параметра решена система алгебраических уравнений методом Крамера. Используя дополнительное условие, относительно основной неизвестной функции получено нелинейное интегральное уравнение типа Вольтерра второго рода, и относительно функции восстановления получено специальное интегральное уравнение типа Вольтерра первого рода. Применен метод последовательных приближений в сочетании с методом сжимающих отображений. Далее определяется функция восстановления. Данная работа является дальнейшим развитием теории интегро-дифференциальных уравнений типа Фредгольма с вырожденным ядром.

The Shudder of a Cinephiliac Idea? Videographic Film Studies Practice as Material Thinking
Authors: Grant Catherine
Published: March 2016

Long after the advent of the digital era, while most university-based film studies academics still choose to publish their critical, theoretical and historical research in conventional written formats, a small but growing number of scholars working on the moving image have begun to explore the online publication possibilities of the digital video essay. This multimedia form has come to prominence in recent years in much Internet-based cinephile and film critical culture. In this article, I will consider, above all from a personal perspective looking back at two of the sixty or so videos that I have made, some of the possibilities that these processes offer for the production of new knowledge, forged out of the conjunction of the film object(s) to be studied, digital technologies of reproduction and editing tools, and the facticity of the researcher(s). I will argue that digital video is usefully seen not only as a promising communicative tool with different affordances than those of written text, but also as an important emergent cultural and phenomenological field for the creative practice of our work as film scholars.

Published: March 2016

This study is aimed to evaluate the relationship between the severity of apoptotic and autophagic cell death based on the distribution of Brucella spp. antigens in the lung, liver, kidney, spleen, brain, heart, skeletal muscle, mesenteric lymph node, and thymus tissue from bovine fetuses aborted due to natural infection with Brucella spp. The distribution of Brucella spp. antigens was immunohistochemically examined in the tissues of 16 aborted fetuses from cattle diagnosed with Brucella spp. infection by a polymerase chain reaction (PCR). In addition, immunostaining of primary antibodies for cleaved caspase 3 was performed to detect apoptosis, and immunostaining of Microtubule Associated Protein 1 Light Chain 3 Beta (LC3B) was used to detect autophagy in the Brucella spp.- related abortions. Analysis of cellular death revealed strong immunopositivity in the lung, spleen, kidney, and thymus, moderate immunopositivity in the liver, mesenterial lymph nodes, and heart muscle and slight immunopositivity in the brain and skeletal muscle by staining of Brucellaspp. antigens. According to the immunohistochemical results, the immunopositivity of cleaved caspase 3 and LC3B was extremely high in the lung, thymus, spleen, kidney, and liver tissues. The immunostaining of cleaved caspase 3 in the lung, thymus, and kidney tissues was severe compared to that of LC3B. In the liver, spleen, and mesenterial lymph nodes, the immunopositivity of LC3B was higher than that of cleaved caspase 3. Bacterial antigens were highly evident in the lung, spleen, kidney, and thymus tissues of Brucella spp.-related bovine abortions, and both apoptosis and autophagy played a role in cellular death.

The aim of our study was to investigate if the thyroid axis of newborn calves is affected by prenatal application of propylthyouracil (PTU). The study included 20 late pregnant Holstein cows. One group (n=10) was treated with PTU (4 mg/kg of BW daily) from day 20 before expected calving until the day of calving. The other group (n=10) was non-treated. Placental samples of dams were obtained for measuring mRNA expression of iodothyronine deiodinases type I (D1), type II (D2) and type III (D3). After parturition calves were separated from the dams and included in the study. Blood samples were taken daily from each calf starting on the day of birth until day 7 of age. Blood T3, T4 and TSH concentrations were measured. PCR analysis of the placental tissue revealed an abundance of all three types of placental deiodinases in non-treated cows, and a significant elevation of mRNA levels for all three types of deiodinases after PTU treatment. Calves that originated from dams treated with PTU had significantly lower T3 and T4 and significantly higher TSH concentrations compared to non-treated calves during the first 2 days of life. Starting from day 4 until day 6 of life the opposite effect was observed meaning that calves prenatally exposed to PTU had significantly higher T3 and T4 and slightly lower TSH. Our study, for the first time, provides information related to iodothyronine deiodinases mRNA expression in bovine placenta, and confirm that PTU treatment of pregnant dams provokes depression of thyroid function in newborns during the first days of life.

Published: March 2016

The aim of this study was to determine the potential relationship between variants of the BF gene and litter size in Polish Landrace x Polish Large White sows. To identify polymorphism within the BF gene, the PCR-RFLP method was applied, using specific primers and the SmaI enzyme. The researchers identified the presence of two alleles, T and C, with frequencies: 0.68 and 0.32, giving three genotypes with frequencies: 0.49, 0.37 and 0.14, respectively for TT, TC and CC. Analysis of relationships between the various genotypes of the BF gene and selected reproductive traits showed significant differences. Sows with TT genotype in the BF locus, gave birth to significantly more live piglets in the first litter (10.24) compared with sows with the CC genotype (7.13).

Published: March 2016

The aim of this paper was to investigate the differences in morphometric characteristics and histological structure of m. semitendinosus, between gilts and barrows of German Landrace breed at the end of the fattening period. Morphometric characteristics (weight, length, diameter and cross sectional area) of m. semitendinosus were not significantly different, while gender as a factor influenced the histological properties of this muscle. A very high statistical difference (p<0.01) in the total number of muscle fibers in m. semitendinosus was determined, with gilts having a higher total fiber number. The cross sectional area of fast twitch oxidative (FTO) fibers was significantly higher (p<0.05) in barrows. Gender did not affect the distribution of different fiber types: in both gender, the most present fiber types (48-52 %) were fast twitch glycolitic (FTG), FTO fibers represented 27-30 % of the total fiber number, while slow twitch oxidative fibers (STO) were the least represented (≈ 20 %).

Authors: Gołębiowski Marek
Published: March 2016

In this paper the MTPA, MTPF, constant torque and constant flux control trajectories are presented. These trajectories are calculated for a 6-phase asymmetric insettype SMPMSM generator with the assumption of a certain level of 3rd harmonic current injection. This injection technique increases the generator performance due to the cooperation of the fundamental and 3rd harmonic. The presented trajectories are used for fast control of the generator working in the gearless wind turbine system.

Algebraic Riccati equation based Q and R matrices selection algorithm for optimal LQR applied to tracking control of 3rd order magnetic levitation system
Authors: Kumare Vinodh , Jerome Jovitha
Published: March 2016

This paper presents an analytical approach for solving the weighting matrices selection problem of a linear quadratic regulator (LQR) for the trajectory tracking application of a magnetic levitation system. One of the challenging problems in the design of LQR for tracking applications is the choice of Q and R matrices. Conventionally, the weights of a LQR controller are chosen based on a trial and error approach to determine the optimum state feedback controller gains. However, it is often time consuming and tedious to tune the controller gains via a trial and error method. To address this problem, by utilizing the relation between the algebraic Riccati equation (ARE) and the Lagrangian optimization principle, an analytical methodology for selecting the elements of Q and R matrices has been formulated. The novelty of the methodology is the emphasis on the synthesis of time domain design specifications for the formulation of the cost function of LQR, which directly translates the system requirement into a cost function so that the optimal performance can be obtained via a systematic approach. The efficacy of the proposed methodology is tested on the benchmark Quanser magnetic levitation system and a detailed simulation and experimental results are presented. Experimental results prove that the proposed methodology not only provides a systematic way of selecting the weighting matrices but also significantly improves the tracking performance of the system.

Published: March 2016

The study presents investigations of an influence of various direct current densities on microstructure, residual stresses, texture, microhardness and corrosion resistance of the nickel coatings electrodeposited from modified Watt’s baths. The properties of obtained coatings were compared to the nano-crystalline composite Ni/Al2O3 coatings prepared under the same plating conditions. The similarities and differences of the obtained coatings microstructures visible on both their surfaces and cross sections and determined properties were presented. The differences in the growth character of the Ni matrix and in the microstructural properties were observed. All electrodeposited Ni and Ni/Al2O3 coatings were compact and well adhering to the steel substrates. The thickness and the microhardness of the Ni and Ni/Al2O3 deposits increased significantly with the current density in the range 2 - 6 A/dm2. Residual stresses are tensile and they reduced as the current density increased. The composite coatings revealed better protection from the corrosion of steel substrate than pure nickel in solution 1 M NaCl.

Authors: Dezső A. , Kaptay G.
Published: March 2016

A general form of material balance equations to be used to calculate quasi-binary sections of multi-component phase diagrams is derived here. When this general equation is reduced to ternary systems, it coincides with those, given in the Thermo-Calc manual. For a k-component system, altogether only (k-2) such independent equations should be written from the list of k(k-1)/2 possible equations.

Published: March 2016

The paper presents the methods of obtaining photovoltaic structures based on CdXHg1-XTe graded-band-gap epitaxial layers. Barriers in these structures were formed by solid phase doping of the material with low-diffusing impurities (As). High-temperature diffusion of acceptor impurity (As) in intrinsically defective material of n-type conductivity as well as ion introducing the donor impurity (B) in uniformly doped during the epitaxy process material of p-type of conductivity have been used. The possibility of creating multi-element graded-band-gap photovoltaic structures suitable for broad band detection of infrared radiation as a result of epitaxial growth by evaporation-condensation-diffusion method has been demonstrated.

Authors: Węglowski M. St. , Zeman M. , Grocholewski A.
Published: March 2016

In the present study, the investigation of weldability of ultra-high strength steel has been presented. The thermal simulated samples were used to investigate the effect of welding cooling time t8/5 on microstructure and mechanical properties of heat affected zone (HAZ) for a Weldox 1300 ultra-high strength steel. In the frame of these investigation the microstructure was studied by light and transmission electron microscopies. Mechanical properties of parent material were analysed by tensile, impact and hardness tests. In details the influence of cooling time in the range of 2,5 ÷ 300 sec. on hardness, impact toughness and microstructure of simulated HAZ was studied by using welding thermal simulation test. The microstructure of ultra-high strength steel is mainly composed of tempered martensite. The results show that the impact toughness and hardness decrease with increase of t8/5 under condition of a single thermal cycle in simulated HAZ. The increase of cooling time to 300 s causes that the microstructure consists of ferrite and bainite mixture. Lower hardness, for t8/5 ≥ 60 s indicated that low risk of cold cracking in HAZ for longer cooling time, exists.
