Authors: Uchirova M. Yu. , Ilin L. A. , Khudyakov S. V.
Published: December 2020

The article considers the main approaches to the development and evaluation of the organization’s logistics strategy based on the application of bifurcation theory. The paper notes that the greatest competitive advantages in the process of carrying out activities can be obtained by the company when designing a unique logistics strategy based on the individual features of the organization’s logistics system. The authors reveal that the bifurcation theory allows you to determine the conditionality of a qualitative dynamic change in the behavior of a logistics system by an infinitesimal change in certain parameters of the system. As part of the assessment of the organization’s logistics management strategy, bifurcation theory forms the basis for determining shift in the qualitative parameter of the system and makes it possible to assess the effect of this parameter on the behavior of the entire system as a whole and each functional subsystem separately. The study reflects that it is possible to determine the critical values of individual variables, when overcoming which the logistics system itself goes into unstable state. The main concept defining the process of critical transition of the state of the logistic system is the bifurcation point.

Published: December 2020

Abstract: It has been previously found that through an established synthesis of the macrocycle boron subnaphthalocyanine (BsubNc) that random bay-position chlorination occurs and results in a mixed alloyed composition that cannot be separated; called chloro-(chloron)-boron subnaphthalocyanines (Cl-ClnBsubNcs). Through modifications of the synthetic method, amounts of the average bay-position chlorination can be varied. Cl-ClnBsubNcs are fluorescent and therefore here we explore the effect of the amount of bay-position chlorination on the photoluminescent and electroluminescent properties of Cl-ClnBsubNcs. Distinct from previous reports detailing the positive impact of higher average bay-position chlorination, we find that the photophysical processes important to OLEDs improve with lower average bay-position chlorination. A higher degree of bay-position chlorine shows higher nonradiative recombination rates, lower photoluminescence quantum efficiencies and a basic OLEDs exhibits a greater host emission fraction, implying less effective energy transfer. These results advance the consideration of subnaphthalocyanines for light-emitting and optoelectronic applications.

Современные методы лечения онкологической патологии значительно улучшают выживаемость пациентов и снижают смертность от рака. Тем не менее, осложнения от такой противоопухолевой терапии нередко оказывают неблагоприятное воздействие на сердечно-сосудистую систему. В результате прямого влияния лучевой и химиотерапии на сердце происходит повреждение структур сердца, с развитием дисфункции сердечной мышцы и/или сердечной недостаточности, которое и определяется как кардиотоксичность. Поэтому, наиболее очевидным остается тот факт, что для успешного лечения таких пациентов необходима совместная работа, как онкологов, так и кардиологов. Данная статья посвящена относительно новой области медицинской науки, которая призвана своевременно выявить и предупредить развитие различных кардиотоксических эффектов при лечении онкологических заболеваний — кардиоонкологии. В работе излагаются основные направления деятельности кардиоонкологической дисциплины, приводятся данные об уже известных положениях и обсуждаются вопросы, требующие дальнейшего внимания со стороны смежных специалистов, которые и могут послужить фундаментом для будущих исследований, что значительно расширит наше представление о патогенетической связи онкологической патологии и кардиоваскулярных заболеваний.

In this case, boron noticeably distorts the anion sublattice of the crystal, changing the lengths of the < O - O > bonds, increasing the ordering of structural units of the cation sublattice. At the same time, boron changes the polarizability of the oxygen-octahedral MeO clusters (Me - Li, Nb) which determines the ferroelectric and nonlinear optical properties of the crystal.

Исследована кинетика проницаемости и диффузии водорода в гидрированых мембранных сплавах на основе Fe и Ni, обладающих функциональными характеристиками, конструкционной прочностью и термостабильностью, и являющихся многообещающей альтернативой дорогим палладиевым сплавам. Изучены прочностные характеристики, термостабильность и устойчивость к водородному охрупчиванию. Рассмотрены механизмы структурирования, диффузии и проницаемости водорода в кристаллическом, аморфном, нанокристаллическом состояниях. Для мембранных сплавов особо важным аспектом является сочетание в открытых структур (аморфных и ОЦК), в то время как для аккумулирования водорода, помимо каналов транспорта (диффузии и проницаемости) также необходимы и высокоплотные интерметаллидные кластеры. Отмечено, что при длительной эксплуатации вследствие возникновения плотных кластерных конфигураций среднего упорядочения, сокращающих диффузионные каналы, начинается снижение через них транспорта водорода.

The kinetics of hydrogen permeability and diffusion in hydrogenated membrane alloys based on Fe and Ni have been investigated, which have functional characteristics, structural strength and thermal stability, and are a promising alternative to expensive palladium alloys. The strength characteristics, thermal stability and resistance to hydrogen embrittlement have been studied. The mechanisms of structuring, diffusion and permeability of hydrogen in crystalline, amorphous, nanocrystalline states are considered. For membrane alloys, a particularly important aspect is the combination in open structures (amorphous and bcc), while for hydrogen accumulation, in addition to transport channels (diffusion and permeability), high-density intermetallic clusters are also required. It is noted that, during long-term operation, due to the appearance of dense cluster configurations of intermediate ordering, which shorten the diffusion channels, the transport of hydrogen through them begins to decrease.

Исследована нанотопография технических поверхностей деталей из высоколегированной термообработанной стали и электротехнического серебра после финишной механической обработки. Экспериментально определены функции плотности вероятности параметров нанотопографии - высот выступов и радиусов кривизны их вершин, которые необходимы для теоретического описания процессов контактного взаимодействия технических поверхностей (на примере поверхностей серебра и стали). Установлено, что распределение указанных параметров наношероховатости сильно асимметрично и далеко от нормального. Доказано, что для исследованных поверхностей плотность вероятности указанных параметров наношероховатости адекватно описывается бета-распределением. Достоверность данного заключения подтверждается с помощью критериев согласия Пирсона χ и Романовского.

The nanotopography of engineering surfaces of machine parts made of high alloy heat-treated steel and electric silver after finishing mechanical treatment was studied. The probability density functions of the nanotopography parameters - the heights of peaks and the radii of curvature of their vertices - were experimentally determined. These parameters are necessary for theoretical description of processes of the contact interaction of engineering surfaces (exemplifying on surfaces of silver and steel). It is established that the distributions of the above mentioned nanoroughness parameters are essentially asymmetrical and are far from normal ones. It has been proved that for the studied surfaces the probability densities of the above mentioned nanoroughness parameters are adequately described by the beta-distribution. The validity of this conclusion is confirmed by the fitting criteria such as χ (K. Pearson’s criterion) and Romanovsky’s criterion.

В рамках работы на кремниевых солнечных элементах были получены полимерные функциональные покрытия с наночастицами серебра. Размер наночастиц, использовавшихся для создания покрытий составил ~ 100 нм. Впервые была исследована микроструктура полученных покрытий методом сканирующей электронной микроскопии. Было показано, что наночастицы имеют достаточно высокую и равномерную плотность распределения в покрытии. В покрытиях, полученных с помощью метода осушения присутствуют единичные дефекты в виде отсутствия пленки. Данные дефекты предположительно обусловлены перепадами микрорельефа на поверхности солнечных элементов и могут быть устранены путем повторного нанесения пленки. Проведенные экспериментальные исследования квантового выхода фотопреобразователей показали, что функциональные покрытия на основе полимеров с наночастицами серебра позволяют существенно улучшить характеристики кремниевых солнечных элементов.

Within the framework of this study, functional polymer coatings with silver nanoparticles were obtained on the surface of silicon solar cells. The size of the nanoparticles used to create the coatings was ~ 100 nm. For the first time, the microstructure of the obtained coatings was investigated by scanning electron microscopy. It was shown that nanoparticles have a sufficiently high and uniform distribution density in the coating. In the coatings obtained using the drying method, that there are single defects in the form of the absence of a film. These defects are presumably due to differences in microrelief on the surface of solar cells and can be eliminated by reapplying the film. Experimental studies of the quantum yield of photoconverters have shown that functional coatings based on polymers with silver nanoparticles can significantly improve the characteristics of silicon solar cells.

В представленной работе рассмотрен поверхностный слой угольного вещества, структура и характеристики которого отличны от структуры объема. Этот слой имеет два уровня: d(I) равный 151,5 нм и d(II)≈10 ⋅ d равный 1515 нм для антрацита. Для чистых металлов d(I) равно 1 - 6 нм, что на 2 порядка меньше поверхностного слоя угольного вещества. Толщина этого слоя имеет порядок толщин высших фуллеренов С, равного 135 нм. Все эти особенности угольного вещества, имеющего углеродную основу и представляющего собой полимер с надмолекулярной структурой, приводят к тому, что именно поверхностный слой определяет физические процессы в нем, связанные с протеканием газов и жидкости, а также с явлениями взрывоопасности.

In the present work, the surface layer of a coal substance is considered, the structure and characteristics of which are different from the bulk structure. This layer has two levels: d (I) equal to 151,5 nm and d(II) ≈ 10 ⋅ d equal to 1515 nm for anthracite. For pure metals d(I) is equal 1 - 6 nm, that is 2 orders of magnitude lesser than the surface layer of the coal substance. The thickness of this layer is of the order of 135 nm for the higher C fullerenes. All these features of a coal substance, which has a carbon base and is a polymer with a supramolecular structure, lead to the fact that it is the surface layer that determines the physical processes in it associated with the flow of gases and liquids, as well as with the phenomena of the explosion hazard.

Изучена зависимость фазового состава наноразмерных фосфатов магния (MgNHPO·6HO, Mg(HPO), MgHPO·3HO, Mg(PO)•22HO) с размером кристаллитов 13-54 нм от условий осаждения из водных растворов в присутствии поливинилового спирта и его смеси с поливинилпирролидоном. В полимерной матрице дополнительно образуется примесная фаза MgOHCl. Наличие средних и двузамещенных фосфатов магния в пленках поливинилового спирта и поливинилового спирта/поливинилпирролида ингибируют их термическую деструкцию.

The dependence of the phase composition of nanoscale magnesium phosphates (MgNHPO·6HO, Mg(HPO), MgHPO·3HO, Mg(PO)•22HO) with 13-54 nm crystallite size on the conditions of precipitation from aqueous solutions in the presence of the polyvinyl alcohol and its mixture with polyvinylpyrrolidone was studied. In the polymer matrix an additional impurity phase MgOHCl is formed. The presence of medium and disubstituted magnesium phosphates in polymer films of polyvinyl alcohol and polyvinyl alcohol/polyvinylpyrrolidone inhibit their thermal destruction.

EXTRAJUDICIAL KILLINGS: AN OPPOSITE IDEA OF PROTECTION UNDER ARTICLE 35(5) OF THE CONSTITUTION OF BANGLADESH
Authors: Monia Shadika Haque
Published: December 2020

Extrajudicial killings indicate a poor as well as a paralyzed criminal justice system. It is also opposite to the protection mentioned under Article 35 (Protection in respect of trial and punishment) of the constitution of Bangladesh. Although as a supreme law of the country the constitution provides some distinct protections, in the context of criminal justice system the idea of extrajudicial killings explains different scenario which are absolutely contradictory to the legal protection ensured by the constitution. The fundamental purpose of a criminal justice system is not to punish an innocent, rather control crime for maintaining peace in the society. This article will endeavour to critically analyse the extra-judicial killings in the light of Article 35(5) of the constitution of Bangladesh, will critically evaluate the differences between theory and practice as well as contradictory ideas regarding extrajudicial killings and the enforcement of Article 35(5) of the constitution from different perspectives.

Indonesia has published and released a new normal life, even though the COVID-19 rate continues to increase. The term of new normal life includes specific preventive behaviors as daily activity and supported skill by adequate health literacy of COVID-19. The purpose of this study was first to analyze the correlation of information media exposure to health literacy levels of COVID-19 and second to analyze the correlation between health literacy levels of COVID-19, exposure of information media to the adaptive behavior in COVID-19 prevention of young adult in East Kalimantan. The research design was a cross-sectional, quantitative study. The sampling technique used accidental sampling (254 young adults) data was taken by Google form. In data analysis to determine the correlation between gender to the level of health literacy of COVID-19 and new normal life used the Chi-square test. The analysis of age, exposure of mass and non-mass media to the level of health literacy of COVID-19 and, HL to new normal life behavior by using Spearman analysis test. The result statistics by gender (p=0.748), age (p=0.323), and health literacy level of COVID-19 (p=0.788) were not associated with the behavior of transmission of COVID-19 and prevention in new normal life. The variable of information exposure (by non-mass media and mass media) has a significant value associated with the variable of the behavior of new normal life (p-value <0.001). The higher exposure of information media through mass and non-mass media have a correlation to increasing the health literacy level of COVID-19 and behavior to prevent the disease.

Objetivo. Describir la implementación del Programa de continuidad de cuidados y rehabilitación (PCC-R) en centros de salud mental comunitaria (CSMC) del Perú.

Métodos. Estudio cualitativo sobre la implementación del PCC-R en cuatro CSMC de Lima y La Libertad, Perú. Se realizaron 42 entrevistas semiestructuradas individuales y un grupo focal con cinco participantes, para un total de 47 informantes entre usuarios, familiares y profesionales vinculados al diseño, la implementación y el monitoreo del PCC-R.

Resultados. El PCC-R es un programa central de los servicios de salud mental comunitaria en Perú, goza de amplia aceptación y los prestadores y usuarios refieren estar satisfechos con sus resultados. Sin embargo, el programa carece de un documento normativo que detalle sus objetivos, organización y actividades, lo que explicaría la variabilidad en su aplicación. Existen limitaciones en la gestión de recursos financieros y humanos del PCC-R y necesidades de capacitación y supervisión, que deben ser mejoradas. Existe consenso sobre la necesidad, la utilidad y la viabilidad de desarrollar un sistema de monitoreo del PCC-R. Se recogen buenas prácticas y sugerencias para enfrentar estos retos.

Conclusiones. El PCC-R es un programa insignia de los CSMC y de la reforma de la salud mental en Perú, y ha logrado amplia aceptación entre los prestadores y usuarios. Su implementación combina aciertos y dificultades, y revela tareas pendientes como desarrollar un documento normativo, mejorar la gestión de recursos, fortalecer la capacitación y acompañamiento, y aplicar un sistema de monitoreo para favorecer la mejora continua del programa.
