Authors: Abulkhanov S. R.
Published: May 2017

In article results of determination of eigenfrequencies of a design of a searchlight of an electric locomotive of the VL series by means of program system of the final and element analysis of ANSYS are stated. The solid-state model of a searchlight having physics and technology parameters of components of a design and the geometrical sizes of a real searchlight was developed for the analysis of vibrostability of a design. As a light source of a front lamp the incandescent lamp and light-emitting diodes were used. Thus for a light-emitting diode the boss from the ceramic material preventing thermal deformations of a substrate was designed. The quantity of light-emitting diodes was chosen, proceeding from lighting requirements to illuminants on the Russian railroad. The analysis of solid-state models of the searchlight using as a light source the incandescent lamp and light-emitting diodes, showed that the searchlight design with light-emitting diodes has weight on 900 grams bigger than a searchlight with the incandescent lamp. The received sizes of eigenfrequencies were compared with frequencies of periodic vibrations which are tested by the rolling stock. For frequencies of vibrations, possible on railway locomotives, deformations of two designs of a searchlight which showed were defined that shortcomings are inherent in both designs. When using as an incandescent lamp light source eigenfrequencies of a design promote destruction of a flask of a lamp, both on top, and at low frequencies of the fluctuations inherent in a range of vibrations of the locomotive. In case of use of light-emitting diodes in a searchlight nature of deformations of a design indicates the need of reduction of its component weight at preservation of necessary rigidity. The carried-out analysis allowed to reveal the directions of development of a design of the searchlight, vibrostability of a searchlight providing increase with a LED light source: application of edges of rigidity and facilitating grooves.

Published: May 2017

This paper presents the proven analytical apparatus for determining the complex stress state in the material of the linear part -main pipeline with stress corrosion cracking in the form of fine crack colonies. The critical stresses are defined and an analytical dependence for calculation of the allowed internal pressure for the damaged pipeline, not satisfactory to strength conditions is received. The above calculation model of stress state is different from their counterparts in that it is not limited by standard methods based solely on the weakened section, and takes into account the stress concentration in the surface defect zone, which has a positive effect on the accuracy of estimated parameters. Introduced additional conditions during selection of permissible stresses ensures the correctness of strength calculations, especially in cases where there are corrosion cracks with relatively large depth in the pipe wall. Additionally, in the present method it is possible to consider the influence of the thermal component to the complex stress state. The presented theoretical apparatus was confirmed with finiteelement modeling in Ansys Mechanical software environment. The results of the practical implementation of this work are given recommendations on assessing the technical condition of pipes with crack defects of different nature, as well as determination of the maximum allowable working pressure, which meets strength conditions on gas pipelines susceptible to stress corrosion cracking.

The solutions of the fundamental problems to determine the structural and hydrodynamic characteristics of the MR material. The paper determines the possibility of creating a filter element, based on a given flow to ensure its performance and service life. We propose an algorithm for calculating the basic characteristics of the filter elements. It includes the solution of the system, and together with them the use of recommendations for selecting parameters of the structure and geometry of the MR material filter elements to ensure their desired filtering and hydrodynamic characteristics. This lets the rational parameters of the material structure with geometric MR material, filter and hydrodynamic characteristics of the filter elements. Such a generalized approach to the calculation of flow characteristics also provides an opportunity to take into account the life of the filter element. The use of the results is essential in the practice of creating high-performance filters based on thin-walled structures rational filter elements of bush type of woven wire MR material.

Published: May 2017

This work is devoted to the two methods of modeling porous material. Flow characteristics and, accordingly, the viscous and inertial coefficients for the models of porous materials consisting of spherical particles were obtained by calculation. On the basis of these data conformity assessment of flow characteristics for models of porous materials consisting of spherical particles of arbitrary filling and exactly the same on the geometrical dimensions of the flow model in accordance with Darcy's law was carried out. The data thus obtained were then used to estimate the energy dissipation due to viscous friction in the flow of fluid through the porous body. As a result reached the following conclusions. Firstly, in the absence of information about the viscous and inertial factors that determine the performance curve, data rates with sufficient accuracy can be obtained by calculation in the medium Ansys CFX for periodic fragment of the porous body. Secondly, there is a satisfactory agreement between flow performance for porosity 0,1601 obtained in the medium Ansys CFX for periodic fragments of porous bodies and flow model in accordance with Darcy's law.

The economic degree of increase of pressure is determined as the function of the degree of heating at the second stage, as it provides the maximum of work increase in the complex cycle compared with that in the simple cycle. The effective efficiency of the complex cycle with the selection of air for intermediate combustion chamber cooling is found by summing up the effective efficiency of the simple regenerative cycle for the part of air, selected on cooling, and that of the complex cycle with intermediate heating of the other part of the air. It is found that the effective efficiency of the complex cycle with the selection of air for intermediate combustion chamber cooling and its regenerative heating is higher than that without the selection of air and the effective efficiency of the complex cycle as well as the work of this cycle reaches its maximum at economic the degree of increase of pressure in the simple cycle.

Experiment on storage stability and performance of aqueous and dry formulation of Helicoverpa armigera nuclear polyhedrosis virus (HaNPV) was conducted during 2011-2013 in Bio control laboratory, Department of Entomology and Insect Biotechnology laboratory, Biotechnology Centre, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with an objective to develop potent HaNPV formulation for improving shelf life and performance. Aqueous and dry form of HaNPV formulations with antimicrobials, UV protectant and phagostimulant were prepared and studied their shelf life and performance during storage. Synthesized and characterized the Silver nanoparticles. Prepared fresh Ha NPV required for preparing different formulation. The contaminants associated, storage stability and larvicidal activity of formulated HaNPV was studied. Data revealed that, HaNPV formulations having Silver nanoparticles @ 8 μl/ml of HaNPV and 80 μl/ml of HaNPV checked the bacterial contamination up to 13 months of the storage period, did not affect the viability of POBs and insecticidal properties of HaNPV formulation. Aqueous form of HaNPV + Streptomycin @ 0.18 g/lit of HaNPV + Tinopal 1% + Sucrose 1% , dry form of HaNPV + Streptomycin @ 0.18 g/lit of HaNPV + Tinopal 1% + Sucrose 1% and HaNPV + Streptomycin @ 0.18 g/lit of HaNPV + sucrose remain stabled up to 12 months. However, aqueous form of HaNPV alone reduces the insecticidal properties from the 9th month of storage period. While, dry form of HaNPV alone reduces the insecticidal properties from the 12th month of storage period. From the result, it was noticed that dry form of HaNPV formulation having antimicrobial found more stable than aqueous form.

Authors: Prasad R. D. , Navaneetha T. , Venkateswar Rao L.
Published: May 2017

Nine potential Trichoderma strains were tested for mycoparasitic, defence enzyme activity and root colonizing behaviour against Macrophomina phaseolina and Fusarium oxysporum f. sp. carthami in safflower (Carthmus tinctorius L). Among them three strains viz., T. harzianum Th4d, T. asperellum TaDOR7316 and T. asperellum Tv5 were found to be most effective showing superior antagonistic activity. Hyphal interaction studies revealed that the inhibition was caused by an interaction that took place in close contact with the host hypha, causing lysis, swelling and coiling of mycelia resulting potentially reduced mycelial growth of M. phaseolina and showed lytic enzymes activity to various extent in Th4d, Tv5 and TaDOR 7316. These strains were also able to solubilize inorganic (P). Increased activity of defense related enzymes viz., peroxidase (PO), polyphenol oxidase (PPO) and phenylalanine ammonia-lyase (PAL) activity in these three potential strains pre-treated safflower plants challenged with M. phaseolina was observed. PO, PPO and PAL activity was also increased two-three folds more in all these bioagents. Interaction between the bioagents and the safflower root system showed profuse adhesion of hyphae to the plant roots as well as colonization of the root epidermis and cortex cells but not the vessels at early stages of safflower root system. Levels of hydrogen peroxide (H2O2) in the bioagents treated leaves and untreated (control) were determined microscopically. Application of these bioagents under field conditions reduced the incidence of root rot and Fusarium wilt, increased growth and plant biomass to a reasonable extent with better root colonization, which is directly correlated with the resistance of the plant against infection and high seed yield, was observed with bioagents treatment. Thus, it is evident that the hyphal interaction and enzymes play a key role to stimulate the defense mechanism which aid in disease management as well as plant growth promotion of the host plant against pathogen attack.

Published: May 2017

A study was undertaken to explore effective organic substrate-based bioformulation using virulent cells of antagonists Pseudomonas fluorescens, Bacillus subtilis and Trichoderma viride during 2010-13. Three organic substrates, viz. vermicompost, farm yard manure and mustard oil cake (MOC) were compared for mass multiplication of the antagonists. All the substrate based antagonists showed effective results in suppression of bacterial wilt (Ralstonia solanacearum Yabuchi et al.) incidence in vegetable crops tomato, brinjal and chill. Quantitative aspect of population dynamics of the antagonists at different days of storage was made to evaluate the shelflife of the biopesticide and found that the antagonists maintained a steady population count upto 180 days of storage at room temperature. The combination of vermicompost P. fluorescens, carboxy methyl cellulose (CMC) and mannitol showed best shelf-life as it maintained highest population recovery of P. fluorescens and B. subtillis at different days of storage. The combination of MOC, T. viride, CMC and mannitol showed best shelf-life in case of T. viride and maintained highest population recovery of the antagonist at different days of storage. Application of the substrate based bioformulations as combination of seed treatment, root application, soil application at transplanting and soil application at 30 days after transplanting showed minimum wilt incidence and maximum yield in tomato, brinjal and chilli. Maximum disease reduction (81.85%) was shown by bioformulation comprising P. fluorescens with vermicompost as substrate followed by T. viride with MOC as substrate (79.07%). Following the trend of reduction in disease incidence, yield was maximum in tomato (36.0 t/ ha), when the crop was treated with vermicompost based P. fluorescens followed by treatment with MOC based T. viride (33.35 t/ha). Yield of brinjal (27.60 t/ha) and chilli (26.30 t/ha) was similarly maximum when bioformulation of vermicompost based P. fluorescens was applied.

Published: May 2017

Este artículo analiza la integración monetaria europea, los determinantes estructurales y los elementos disfuncionales de las instituciones de la Unión. Además, revisa dos lecturas que fallan al interpretar los acontecimientos: una interpretación ideológica que ve en la integración un proceso de convergencia que no se debe interferir, y una visión idealista que sostiene que la integración debe prevalecer sobre toda contradicción generada a nivel institucional. Su combinación sirvió para justificar las intervenciones poscrisis (la austeridad) y la construcción institucional posterior, que agravaron la inestabilidad macroeconómica en Europa.
A New Arithmetically Incomplete First-Order Extension of Gl All Theorems of Which Have Cut Free Proofs
Authors: Tourlakis George
Published: May 2017

Reference [12] introduced a novel formula to formula translation tool (“formula-tors”) that enables syntactic metatheoretical investigations of first-order modallogics, bypassing a need to convert them first into Gentzen style logics in order torely on cut elimination and the subformula property. In fact, the formulator tool,as was already demonstrated in loc. cit., is applicable even to the metatheoreticalstudy of logics such as QGL, where cut elimination is (provably, [2]) unavailable. This paper applies the formulator approach to show the independence of the axiom schema ☐A → ☐∀ A of the logics M3and ML3 of [17, 18, 11, 13]. This leads to the conclusion that the two logics obtained by removing this axiom are incomplete, both with respect to their natural Kripke structures and to arithmetical interpretations.  In particular, the so modified ML3 is, similarly to QGL, an arithmetically incomplete first-order extension of GL, but, unlike QGL, all its theorems have cut free proofs. We also establish here, via formulators, a stronger version of the disjunction property for GL and QGL without going through Gentzen versions of these logics (compare with the more complexproofs in [2,8]).

Metafory synestezyjne w utworach Vladimira Nabokova
Authors: Ginter Anna
Published: May 2017

Niniejszy artykuł poświęcony jest metaforom synestezyjnym w twórczości Nabokova. Uwaga skierowana jest głównie na metafory, w których zarówno domena źródłowa, jak i docelowa dotyczą wrażeń zmysłowych. Wiele przedstawionych podczas analizy konstrukcji dowodzi, że choć w pewnych przypadkach rodzaj modalności wydaje się określony w sposób oczywisty, to obrazowanie językowo odnosi się do jednej lub dwóch odmiennych modalności percepcyjnych.Nabokovowskie konstrukcje metaforyczne zostały omówione w dwóch grupach: międzymodalne metafory z kolorem jako domeną źródłową oraz metafory z domeną źródłową związaną z percepcją dotykową. Konstrukcje te niewątpliwie przypominają synestezję, choć w przeciwieństwie do synestezji uwarunkowanej neuropsychologicznie, znaczenie metafor synestezyjnych powstaje w rezultacie procesów semantycznych. Interpretacja metafor międzyzmysłowych jest uwarunkowana kontekstualnie.
Понятия абсолютный/относительный признак в контексте языковой параметризации (на материале русского и болгарского языков)
Authors: Петкова-Калева Стефка Янчева
Published: May 2017

В статье рассматриваются проблемы языковой интерпретации категории размера. В фокус внимания ставятся понятия абсолютный/относительный признак. В качестве форм абсолютной параметризации рассматриваются языковые и речевые единицы, порождающие в индивидуальном сознании одно и то же (и именно в этом смысле абсолютное) представление об объективных физических параметрах предмета (процесса). В рамках относительной параметризации выделяются нормативный и ненормативный аспекты. Нормативный аспект параметризации связывается с соотнесением размерного признака с четырьмя разновидностями норм: нормой вида (среднестатистического стандарта), нормой ожидания, ситуативной (модальной) нормой и нормой пропорций. К формам выражения относительного определения размера, выходящего за рамки нормативной оценки относятся языковые дескрипции, интерпретирующие размер с точки зрения соотношения в представлении признака у различных носителей и с точки зрения его динамики во времени. Более подробно, на материале русского и болгарского языков, рассматриваются экспонентные структуры, связанные с обозначением ситуативной (модальной) нормы.

Данная статья посвящена исследованию ключевого концепта русской лингвокультуры ‘святой’. Актуальность данного исследования связана с возросшим интересом в современном мире к стратегии формирования ценностно-нравственных установок общества и поддержания культуры в целом. Детальное исследование лексико-семантического поля заявленного концепта с привлечением лексикографических источников позволило сделать определенные выводы относительно трансформации семантического значения концепта в истории русского языка: отмечается постепенное отмирание несакральных значений. Обращение к журналисткому дискурсу дало возможность установить частотность употребления светских и сакральных значений концепта в современном русском языке. Был сделан вывод о том, что соотношение светских и религиозных значений концепта ‘святой’ напрямую связано с культурной эпохой.

Published: May 2017

Формализация модели знака должна предполагать возможность установления классификационных семантических параметров описываемой единицы через разные степени сочетаемости. Для этого требуется установление набора наиболее релевантных маркеров стиля и дискурса, а также морфологических и деривативных маркеров лексико-грамматической принадлежности знака его типовой синтаксической и семантической функции. Первые должны служить установлению ситуативно-речевых свойств текста, что позволит отфильтровать стилистически и социолектно нерелевантные омонимичные и омонимоидные знаки (полисемы), вторые же – поиску смежно связанных с анализируемым знаком единиц текста, которые помогут отфильтровать стилистически и социолектно однородные омонимы и омонимоиды (полисемы).
Семантика невыразимого в современных гуманитарных изысканиях
Authors: Михайлова Марина
Published: May 2017

Статья содержит краткий обзор представленности семантики невыразимого в современных гуманитарных исследованиях. В ней обозначены философско-методологические основания изучения невыразимого, а также определен грамматический стержень семантики невыразимого – это категория отрицания (негации). Семантика невыразимого сопоставлена с другими активно востребованными в современных гуманитарных изысканиях смежными понятиями (апофатизмом, феноменом невыразимого в экфрасисе, поэтикой и методологией романтизма). Определены и охарактеризованы основные направления изучения невыразимого в литературоведении. Исчерпывающим образом названы исследовательские парадигмы лингвистики, в которых статьями или попутными рассуждениями и замечаниями изучается семантика невыразимого: лингвопоэтика, когнитология, этнолингвистика, структурно-семантическое направление в российской лингвистике (научной школы В. В. Бабайцевой), смежные, междисциплинарные исследования. Показана асимметрия в иерархии функционально-семантической категории невыразимого и активных средств передачи названной семантики в художественном тексте.

Milionerzy – nowa grupa społeczna w regionie łódzkim
Authors: Dzieciuchowicz Jerzy
Published: May 2017

Przedmiotem tego opracowania jest przede wszystkim struktura przestrzenna milionerów w województwie łódzkim i jej zmiany w 2014 roku. Analizie poddano również ważniejsze rodzaje działalności gospodarczej osób najbogatszych. Na przykładzie Antoniego Ptaka przedstawiono drogę kariery społeczno-zawodowej przedstawicieli tej grupy społecznej. Problematyka ta jest rozważana na tle pozycji przypisanej najbogatszym elitom w teorii struktur i zmian społecznych, a także rankingów osób najzamożniejszych w Polsce i na świecie. Uwzględnione zostały przy tym dwie kategorie milionerów wyróżnione w oparciu o kryterium dochodowe i majątkowe. Cel pracy stanowi ustalenie wyróżniających właściwości struktury przestrzennej i układów terytorialnych cechujących najzamożniejszych mieszkańców województwa łódzkiego, dynamiki zmian ich liczebności, jak też głównych dziedzin aktywności ekonomicznej.
Zagadnienia przestrzenne a postulaty i idee ruchu miast cittaslow
Authors: Blazy Rafał
Published: May 2017

Ruch Slow City lub Cittaslow rozpoczął się od stowarzyszenia czterech włoskich miast w 1999 roku. Od tej pory rozwija się niezwykle prężnie w Europie i poza jej granicami. W Polsce w chwili obecnej stowarzysza on 20 miast. Ruch ten zmierza do rozwoju małych miasteczek w oparciu o kryteria mające na celu poszanowanie jakości życia w duchu ideologii „slow life”. W swoim programie zawiera prototypowy system kwantyfikacji czynników, które decydują o nadaniu miastu tytułu Slow City. W odniesieniu do zagadnień przestrzennych przedmiotowe miasteczka mają stać się miejscami idealnymi dla prowadzenia niepowtarzalnego – zgodnego z naszym zegarem biologicznym, bardziej higienicznego i harmonijnego sposobu życia. Autor w swoim artykule podjął próbę spojrzenia na filozofię ruchu z punktu widzenia zagadnień przestrzennych. Tekst jest przykładem przedstawienia wybranych rozwiązań przestrzennych i urbanistycznych w odniesieniu do postulatów ideowych stowarzyszenia.
Rozwój przestrzenny małego miasta – forma miejska czy podmiejska przykład Słomnik
Authors: Gołąb-Korzeniowska Monika
Published: May 2017

Artykuł koncentruje się na zagadnieniach formy małego miasta, której ewolucja jest determinowana wprowadzaniem ustaleń miejscowego planu. Badania aktualnego zagospodarowania terenu i jego uwarunkowań przestrzennych pozwalają na diagnozowanie najistotniejszych problemów struktury miasta. Analiza miejscowego planu zagospodarowania przestrzennego umożliwia określenie charakteru przestrzeni, która może pojawić się w trakcie jego realizacji, skutków dla porządkowania zabudowy i czytelności układu. Badania przeprowadzono dla miejscowości Słomniki, która jest przykładem małego miasta o zachowanym średniowiecznym rozplanowaniu i typowymi dla małych miast przekształceniami tkanki miejskiej. Równocześnie miasto jest w całości objęte miejscowym planem zagospodarowania przestrzennego uchwalonym w 2015 roku. Celem podjętych badań jest określenie, czy forma przestrzenna jaką przyjmą Słomniki w wyniku realizacji ww. planu będzie kontynuacją ich miejskiego charakteru czy zostanie zdominowana jednorodzinnymi osiedlami upodabniając się do podmiejskiego osiedla. Badania stanowiły rozpoznanie aktualnego stanu zagospodarowania, diagnozujące obecne tendencje w rozmieszczaniu zabudowy oraz zapisy planu sprawdzane pod kątem przyszłego kształtu przestrzeni miasta. Konkluzją artykułu jest stwierdzenie, że realizacja planu daje możliwość utrzymania małomiejskiego charakteru przestrzeni, jednak elastyczność zapisów nie jest tego gwarantem. Dlatego niezwykle istotnym elementem lokalnej polityki przestrzennej jest konsekwencja w przedstawionej w planie polityki przestrzennej.
Zmiany funkcjonalne dworców kolejowych w Polsce i na Ukrainie
Authors: Rochmińska Agnieszka , Roczniak Jurij A.
Published: May 2017

W Polsce i na Ukrainie terenami kolejowymi zarządzają przedsiębiorstwa państwowe. Obydwa kraje borykają się z problemem dekapitalizacji majątku kolejowego, szczególnie przy nieczynnych liniach. Celem artykułu jest przedstawienie sytuacji dworców kolejowych w małych i średniej wielkości miastach w Polsce i na Ukrainie ze szczególnym zwróceniem uwagi na zmiany w ich zagospodarowaniu i związanymi z tym zmianami funkcjonalnymi. Dworce te stanowią majątek, który ze względu na rozwój kolejnictwa i transportu drogowego tracą w niektórych miejscowościach swoje znaczenie i użyteczność. W obydwu krajach znajdują się obiekty nieodpowiednio zagospodarowane, ulegające niszczeniu i popadające w ruinę. Jedynie zmiana ich przeznaczenia może uchronić budynki przed ostatecznym zniszczeniem. Specyfiką przekształceń na Ukrainie jest adaptowanie małych i średniej wielkości budynków dworcowych na cele mieszkaniowe. W Polsce funkcje mieszkaniowe pojawiają się przy nieczynnych liniach kolejowych (przepisy prawne ograniczają tego typu przekształcenia).

The Role of the Bible in the Formation of Philosophical Thought in Kievan Rus’ (as Exemplified by Ilarion of Kiev, Kliment Smolatič, and Kirill of Turov)
Authors: Kroczak Justyna
Published: May 2017

The article is an attempt to critically evaluate the manifestations of the philosophical culture sprouting in Rus’. With the baptism in the Byzantine Rite, Rus’ in the 10th century joined the family of Christian nations and defined the future direction of her own cultural development. The Middle Ages in Rus’ were eminently theocentric. Literature (which was mostly translated from the Greek in Bulgarian monasteries) had a religious character. Sacral content, assimilated in Rus’ mainly through the Old Church Slavonic (due to the scarce knowledge of Greek) had a decisive influence on formation of the philosophical worldview of Rus’ intellectual elite. The Bible thus became the main reference framework for the first Rus’ thinkers-philosophers: Ilarion of Kiev († 1055), Kirill of Turov († 1183) and Kliment Smolatič († 1164). Ilarion of Kiev, the first metropolitan of the Kievan Rus’ in his rhetoric work (which postulated the superiority of the New Testament to the Old) expressed a philosophical thesis of the equality of all Christian nations before God. Kliment Smolatič, the second metropolitan of Rus’, in his Letter to Presbyter Foma, defended the allegorical method of interpretating the Bible. Kirill of Turov, in his turn, in his Parable of the human soul and body allegorically tried to answer the question about the relationship of the body and the soul. For the Rus’ thinkers the content of the Bible served as a pretext for philosophical reflection, e.g. on the role of man in the universe, on the nature of reality, on the relation between matter and spirit. In their works we find the beginnings of the theory of knowledge, metaphysics, ethics, and aesthetics.
