Nikolai Gogol as a political thinker
Authors: Voropaev Vladimir A.
Published: December 2020

Nikolai Gogol’s political thought was conservative. All questions of life — everyday,
social, state, literary — had a religious and moral meaning for him. Recognising and
accepting the existing order of things, he strove to change society through the transformation of human. The historical and political views of Nikolai Gogol are close to the views of Nikolay Karamzin and the Slavophiles. At the same time, he remained unsurpassed in the religious perception of the West. According to Vasiliy Zen’kovsky, no one else had such a deep direct feeling of the religious untruth of that time. In his interpretation of Russia as a theocratic state, Nikolai Gogol was at odds with Nikolay Karamzin and Alexander Pushkin, but the former was in solidarity with the latters in the sympathies for the nobility as an educated class. Nikolai Gogol came close to the main themes of Russian religious philosophy. He became the first representative of the deep and tragic religious and moral aspiration that had permeated Russian literature in the subsequent decades. The ideal of the churching of Russian life put forward by him is still profoundly significant for Russia to this day. Creators such as Nikolai Gogol, in their meaning in history, in words are similar to the Holy Hierarchs in Orthodoxy.

Published: December 2020

The aim of this paper is to knowledge the problems faced by Islamic banks in Jordan towards the adherence to AAOIFI accounting standards. And to study the problems faced with adherence to AAOIFI accounting standards, a meticulous market survey was conducted from banking (employees of the financial department) in Islamic banks in Jordan – their number 4 – banks. A structured questionnaire was designed and distributed in person among respondents – their number 80 – employees in the financial departments. We are found towards adherence to AAOIFI accounting standards. Internal and external problems are found to adherence Islamic banks to AAOIFI accounting standards. The sample is limited to Islamic banks in Jordan. This is necessitated by the lack of adaptation elsewhere. Also, there is little research in Jordan on adherence to AAOIFI accounting standards developed by this body. This paper, along with the previous study, helps to address this gap.
Recognition of the anatomical structure of the atrioventricular node: Connection between the retroaortic node and the compact node
Authors: Wang Fan , Zhang Lulu , Meng Wei , Zhu Bin , Li Shufeng , Wu Qiuwen , zhang shuo
Published: December 2020

Introduction: The complex electrophysiological phenomena related to the
atrioventricular node (AVN) are due to its complex anatomical
structures. Aside from the inferior nodal extension (INE), other
node-like tissues, such as the retroaortic node (RN), have been less
described and may also share the mechanism of normal conduction and
abnormal conduction in AVN re-entrant tachycardia (AVNRT). Methods:
High-density sections of the entire AVN were obtained from rats and
rabbits. Fibrosis was analyzed by Masson’s trichrome staining. Connexin
(Cx43, Cx40, and Cx45) and ion channel (Nav1.5, Cav3.1, and HCN4)
proteins were immunohistochemically labeled for the analysis of tissue
features. Three-dimensional (3D) reconstruction of the AV junction was
performed to clarify the relationships among different structures.
Results: The RN expressed the same connexin isoforms as the compact node
(CN) and INE. Nav1.5 labeling was present at a low level in the CN, RN
and INE, where Cav3.1 and HCN4 were expressed. The CN connected with the
RN in a narrow strip pattern at the level of the start of the CN. The RN
presented as a shuttle shape and was the only tissue directly connected
with the atrium in the anterior septum. Conclusion: The RN connects with
the AVN anatomically, suggesting that there is direct electrical
conduction between them. The entrance of the atria into the AVN is the
distal part of the RN, which may form the fast pathway of the AVN.
Adjustment of the Early Meets Late Module to Differentiate the Active Circuit of a Dual Loop Reentrant Atrial Tachycardia

Published: December 2020

In dual loop reentrant ATs, the differentiation of the active circuit
from the passive circuit in a dual loop reentry is still challenging. In
such complicated AT cases, entrainment pacing is useful for determining
the dominant circuit. However, we differentiated the active circuit by
an AT activation map with an adjustment of the lower threshold value in
the early meets late module. We also detected the gap of the previous
PVI line by the same map with a further adjustment of the lower
threshold value. The adjustment of the lower threshold might be
advantageous for differentiating an active circuit of a dual loop
reentry as well as gaps along the PVI line.
Investigating carnivore guild structure: Spatial and temporal relationships amongst threatened felids in Myanmar

Published: December 2020

At least nine felid species can co-occur in Southeast Asia, thus
providing an unusual opportunity to investigate poorly known guild
structure and the factors controlling it. Using camera-trap data, we
quantified space use, temporal activity, and multi-dimensional niche
overlap of tiger, clouded leopard, marbled cat, leopard cat, and Asiatic
golden cat in Htamanthi Wildlife Sanctuary of Myanmar. We hypothesized
that the spatio-temporal behaviour of smaller cats can reflect avoidance
of the larger cats, which are both potential competitors and predators,
and similar-sized guild members would partition their niches in space or
time to reduce competition for resources. Our approach involved
single-species occupancy modelling to identify site covariates, pairwise
spatial overlap using Bayesian inference, and activity overlap with
Kernel density estimation and multivariate analyses to test hypotheses.
We found tiger and marbled cats were primarily diurnal, clouded leopard
and leopard cat were nocturnal and golden cat exhibited cathemeral
activity. We observed a complex pattern of guild assembly and potential
competition involving strong niche displacement between the golden cat
and marbled cat, but high overlap between the relatively similarly-sized
pairing of clouded leopard and golden cat, and the markedly
differently-sized tiger – golden cat pairing. No significant evidence
of mesopredator release was observed and the felid assembly in Northern
Myanmar appeared to be partitioned mainly on a spatial, rather than
temporal, dimension. Nonetheless, the temporal association between the
three mesopredators was inversely related to the similarity in their
body sizes. The insights into this felid guild revealed that the largest
niche differences in the use of space and time occurred between the
three smaller species, most evidently between the Asiatic golden
cat-marbled cat pairing, followed by marbled cat - leopard cat pairing.
This study offers new insight into carnivore guild assembly and, adds
substantially to knowledge of five of the least known felids of
conservation concern.
The effect of root rot and bark-stripping on wind stability of Norway spruce (Picea abies (L.) H. Karst.) = Parastās egles (Picea abies (L.) H. Karst.) vēja noturības izmaiņas sakņu trupes un stumbra mizas bojājumu ietekmē

Published: December 2020

Climate change causes gradual decline of economic value of Norway spruce forestry except in boreal and hemiboreal forest zones that will remain suitable for this tree species. However, also in this region frequency and scale of damages caused by natural disturbances (abiotic and biotic factors) are expected to increase. Norway spruce will remain its economic significance and role in carbon sequestration in Latvia, if forest management practices will be changed to prevent or minimize the damages caused by natural disturbances. Information on effect of natural disturbances and their interactions on trees is vital for development of recommendations for adaptation of forestry to climate change. The aim of the thesis is to assess the effect of root rot and bark-stripping on possibility of wind induced damages in Norway spruce stands. Tree mechanical stability was primarily determined by its stem volume; however, the presence of damages, caused by biotic agents, such as root rot and bark-stripping, significantly reduced it. Morphometric parameters of Norway spruce stem and root plate differed significantly between stands on drained peat and mineral soils. Root-rot notably and significantly affected mechanical stability of trees regardless of soil type and volume of root-soil plate, resulting in similar reduction of wind load necessary to cause both primary and secondary failure. Consequences of bark-stripping primarily affected root-soil anchorage, more commonly causing uprooting than stem fracture. Most pronounced was reduction of resistance against primary failure. Changing wind climate, high population density of cervids and presence of root-rot will lead to increased risk of damages caused by (repeated) storms and subsequent legacy effects. The survival of forest stands depends on dimensions of trees and exposure time to different damaging agents, and, at current climate and silvicultural practice, was significantly reduced when transitioning into third age class (41-60 years). Targeted forestry, ensuring planting of improved material, lower initial density, timely precommercial thinning and thus ensuring faster reach of the tree dimension required for final harvest will reduce the time when stands are subjected to significant wind damage risk, thus minimizing the possibility of such disturbance and boosting value of Norway spruce stands.
Convergence theorems for generalized contractions and applications

Published: December 2020

The principal results in this article deal with the existence of fixed points
of a new class of generalized F-contraction. In our approach, by visualizing
some non-trivial examples we will obtain better geometrical interpretation.
Our main results substantially improve the theory of F-contraction mappings
and the related fixed point theorems. In section-4, application to graph
theory is entrusted and proved results are endorsed by an example through
graph. The presented new techniques give the possibility to justify the
existence problems of the solutions for some class of integral equations.
For the future aspects of our study, an open problem is suggested regarding
discretized population balance model, whose solution may be derived from the
established techniques.
Roman and Early Byzantine finds from Japanese Archipelago – a critical survey
Authors: Szmoniewski Bartłomiej Szymon
Published: December 2020

Artifacts discovered on the Japanese archipelago, which are interpreted as being of Roman and Byzantine pro-venance, are critically discussed in the following article. In light of chemical analyses, some of the glass artifacts found, including beads and vessels, are related to the glass typical of Mediterranean workshops. They were imported in the times of their production. New numismatic discoveries from Okinawa, dated to the fourth century, were found in layers associated with the sixteenth and seventeenth centuries, and cannot be contemporaneous with the glass imports. The silk textile from Shōsō-in, despite its superficial similarity to Early Byzantine art products, seems to be a Central Asian/Chinese imitation, probably woven in the workshops of Chang’an. Thus, finds of Mediterranean origin, produced in the Roman and Early Byzantine epochs, are insignificant in their number and their imports were isolated cases. However, their presence supports the thesis that the Japanese archipelago should be included as part of the ancient network of the Silk Road.

The purpose of this study was to evaluate the effect of fertilizer on the growth and yield of jhum crop under the Slush-mulch condition for sustainable crop production in Chittagong hill tracts (CHT) of Bangladesh. The experiments were conducted during March 2015 to February 2016 at Bandarban in Chittagong under the AEZ 29 (Northern and Eastern Hills Tract). The experiment was designed on Randomized Completely Block Design (RCBD) with three replications. Experiment had three treatments as T1 Control T2 Application of 100% chemical fertilizers on STB (N37 P15 K14 S8 kg ha-1) and T3 Application of 125% chemical fertilizers on STB along with mulch (about 50 kg natural weed per 20 m2 plot) and no mulch conditions. Fertilization under slush-mulch condition had a positive role on the yield of Jhum rice and that of other Jhum crops. Under sole application of fertilizer, the highest grain yield of rice (4.27 t ha-1) was obtained from the application of 125%of RDF on STB, the lowest value (2.65 t ha-1) being noted in control. On the other hand, mulching favored the yield of rice grain, the highest grain yield (4.44 t ha-1) being obtained from the combination of mulching along with the application of fertilizers @ 125%RDF on STB, the lowest grain yield (1.89 t ha-1) was recorded from the absolute control. The yield of jhum other crops also significantly influenced in mulch condition. The negative balance of soil nutrient was increased with the rates of fertilizer application under both mulch and no-mulch conditions.

A short statured variety Indica with open type of canopy that matured in 130 days yielded 2246 kg of seed cotton ha-1 with better quality of fibres than the other popular varieties MCU5, MCU5 VT and Surabhi which recorded 6.50 to 12.15% lesser yield in the village farms with lower quality of fibres than Indica. The bleached fibres of variety Indica were brighter white in colour with lower tinge of yellowness than the other varieties. Upon dyeing with a blue and a red reactive dye to 0.5% shade, the uptake of dyes by Indica was more than the other varieties and it left lesser dye in the dye bath irrespective of the dye. The variety MCU 5VT recorded the lowest dye uptake and left more dye residue in the dye bath as compared to the other varieties. The dyed fibres of Indica were darkest in colour with better colour strength than the other varieties which may save some dye costs for the textile industries since a darker colour can be produced with lesser amount of dye. Since Indica left least residual dye, dye effluent from this variety will cause lesser damage to the environment and soil. It may also help the Textile industries to spend less on treatment of dye effluent as lesser quantity of residual dye is likely to be present in it. Use of this cotton variety may thus reduce the overall dyeing costs and make the garments made out of the fibres of this variety to cost less than the other popular cotton varieties.

Tapis Fabric is a traditional clothing of the people of Lampung in the form of a shawl cloth or a sarong made of woven cotton thread with various motifs and ornaments, silver thread or gold thread by embroidered or punched. The pattern of filter cloth is quite complex, unlike the pattern of fabric in general, with its own uniqueness that has become the culture of Lampung society until now. This filter cloth will be investigated by identifying the three types of filter cloth, namely Sasab, Bintang Perak and Gunung Beradu and see the results of its identification. The method used to identify is by combining the Gabor Filter feature extraction method which has frequency and orientation parameters and Probability Neural Network classification methods. Previously, the combination of these two methods was used to identify objects with simple patterns. The results are quite good, such as detecting faces, leaf patterns, and other simple patterns. This research is expected to get maximum identification results on the filter cloth even though it has a pattern that is not simple and will be used as a research report to determine the suitability of the method used for the filter object.

Colombia es uno de los países que se caracteriza por una alta variabilidad espacio – temporal de los parámetros hidroclimatológicos definida por un abanico de diferentes fenómenos macro climáticos. Uno de estos es el fenómeno de la Oscilación Cuasi-Bienal que ha sido poco estudiado en el contexto nacional. En el estudio se llegó a obtener la incidencia de este fenómeno sobre el régimen hídrico de los afluentes del embalse Betania los cuales son importante desde el punto de vista de la producción de hidroenergía y las actividades agropecuarias de la zona. Durante la investigación se encontró que el evento macro climático logra manifestarse en un periodo de 4 a 7 meses y su aporte a la variabilidad interanual de caudales es hasta el 13.7 %, teniendo en cuenta que las intervenciones antrópicas en la zona afectan los niveles de los caudales donde se ven reflejados los resultados al obtener las correlaciones.

Published: December 2020

This paper presents a comparative study of an Optimal Sensor Placement (OSP) implementation conducted in a box girder bridge using experimental and numerical mode shapes obtained at different construction stages. It is widely recognized that monitoring the dynamic response of bridges during different construction stages provides valuable information to adjust design considerations. Therefore, there is a need for the development of OSP implementations in order to find the optimal number of sensors needed for real applications. In the present study, an OPS method based on the maximization of the Fisher Information Matrix (FIM) is used. The use of experimentally derived and numerical based mode shapes is considered in the determination of the optimal sensor locations. Field testing results previously conducted before connecting the central segment of the main span are also included in this study. The asphalt pavement weight effect in OSP determination is also analyzed by considering field testing.

La calibración establece la relación entre las indicaciones de un instrumento de medición y las indicaciones de un equipo patrón, que lleva un instrumento a un estado de funcionamiento conveniente para su uso, no debe entenderse como solo el tomar datos de indicación. Un proceso de calibración completo también lleva consigo la estimación de la incertidumbre de medición, nunca se tiene garantía de que una medición es 100 % correcta, siempre habrá algún grado de “duda”, conocida como incertidumbre de medición. En este trabajo se presenta el desarrollo de un procedimiento de calibración de incubadora neonatal en las variables de humedad relativa y temperatura del aire, siguiendo los lineamientos del Centro Español de Metrología. Se establecieron factores de corrección para cada variable, así los usuarios pueden aplicar las correcciones necesarias para garantizar unas condiciones ambientales óptimas para el recién nacido.

Se estudió las propiedades térmicas (equilibrio de fases) de membranas nanoestructuradas basadas en poli(vinil alcohol) (PVA), quitosano (CS), ácido hipofosforoso (H3PO2) y micropartículas nanoporosas de óxido de niobio (Nb2O5) usando calorimetría de barrido diferencial (DSC) y análisis termo-gravimétrico (TGA). Se prepararon membranas en una combinación PVA-CS 80:20+40%H3PO2+xNb2O5 con x=0.02 hasta x=0.10. Para las medidas de DSC, se observó la transición vítrea de PVA/CS 80:20 en Tg~26°C, para PVA/CS 80:20+40%H3PO2 en 95°C y para las dopadas con Nb2O5 en 110°C. El punto de fusión de PVA y PVA/CS 80:20 fue alrededor de 210°C, para PVA/CS 80:20+40%H3PO2 no se observó claramente, indicando predominio de su fase amorfa. Para las dopadas con Nb2O5, la fusión de sus fases cristalinas fue alrededor de 180°C. Por encima de 430°C, todas las membranas se descomponen. Las curvas TGA de todas las membranas mostraron una pérdida continua de peso al aumentar la temperatura hasta 200°C, esta pérdida es atribuible a la evaporación de moléculas de agua absorbidas en la superficie de la membrana o atrapadas dentro de las cadenas de la matriz del polímero. Por encima de 200°C, se observó que las membranas pierden peso más rápidamente, siendo mayor para las membranas sin dopar con Nb2O5.

Haciendo uso de la aproximación de masa efectiva y de cálculos numéricos con el método de elementos finitos, se reportan las propiedades ópticas y electrónicas de un electrón confinado en un punto cuántico de GaN, en forma de sector cónico esférico. Se reportan los estados electrónicos, el cuadrado del momento de dipolo y los coeficientes de absorción óptica y de cambios en el índice de refracción como funciones del radio y del ángulo apical de la estructura. Del estudio se puede concluir que: i) elecciones adecuadas del ángulo apical y del radio del punto cuántico pueden dar origen a magnificaciones en las propiedades ópticas y ii) corrimientos al rojo de las estructuras resonantes de las propiedades ópticas se asocian claramente con el aumento tanto del ángulo apical como del radio de la estructura.
FISHING IN DRAINING PONDS OF MODERN FISH FARMS

The article describeы the fishing process as a final technological stage that completes the cycle of fish breeding in the fish ponds. Fishing in the ponds, regardless of their category, is a difficult and energy-intensive process. The safety of farmed fish and the overall results of fish farming depend on the process of fishing. The well-known fishing methods are based on filtering fish when discharging water through fish catchers or other artificial structures. When water is drained from the pond, the fish moves to a fish catcher with the water flow, which contradicts its biological tendency to breast the current and prevents from its getting into the fish catcher or another artificial structure.

In addition, the separation of fish from water by a grated water separator leads to the mechanical damage of the fish scales and reduces the number of alive fish. The technology of fish catching in draining ponds used at the small innovative enterprise SRK Sharapovsky (Kamyzyaksky district, Astrakhan region) has been analyzed. The absence of a fish catcher is a specific feature of the technology. Fishing in the ponds is carried out by using a dragnet during the pond drainage, starting the catch when the pond’s area is lowered to 1/3 or 1/4. The disadvantages of this technology include excessive accumulation of fish in a small volume of water, which can cause fish death or severe injuries to the underyearlings reared with commercial fish species. Choosing the optimal fishing gear or a device will allow to clearly plan and coordinate the work of the enterprise, because the fishing period is short and depends on the time frames and the market demands.

Authors: González-Corrales Daniela , Monge-Quirós Tatiana , Alfaro-Mora Ramses
Published: December 2020

El mecanismo de acción de los antiinflamatorios no esteroideos (AINEs) consiste en reducir la producción de prostaglandinas (PG) a través de la inhibición de la enzima ciclooxigenasa (COX). Los pacientes más propensos a los efectos secundarios son aquellos de edad avanzada, debido a la reducción de su metabolismo y la excreción del fármaco. Se recomienda no administrar AINEs en pacientes hipovolémicos, deshidratados o hipotensos, y de especial cuidado en pacientes con disfunción cardíaca, renal, hepática, gastrointestinal y hemostática. Los AINEs han sido ampliamente utilizados en el tratamiento del dolor a largo plazo. La eficacia de carprofeno ha sido respaldada por la mayor cantidad de estudios, seguido por meloxicam y firocoxib. Sin embargo, estos pueden causar ulceraciones gástricas, perforaciones y hemorragias entre otros efectos adversos de tipo gastrointestinal, renal y hepático. Existe una marcada diferencia farmacocinética y farmacodinámica entre caninos y felinos que corresponden a diferencias en el metabolismo. La administración de ibuprofeno por lo general no se recomienda en perros, existe el riesgo de ocasionar efectos adversos como ulceraciones gástricas y perforaciones cuando se utiliza terapéuticamente, y posiblemente por muchos AINEs. El objetivo de esta revisión es describir los principales efectos adversos relacionados al uso de AINEs en felinos y caninos, lograr identificar y seleccionar los que aún hoy en día se pueda administrar como analgésico y antiinflamatorio no esteroideo con fines terapéuticos, en el manejo de inflamación, dolor y fiebre en el manejo de osteoartritis (OA) en estas especies en el control y cuidado en los intervalos de dosificación.

Published: December 2020

El acercamiento entre la Alianza del Pacífico (ap) y el Mercosur ha sido un tema en discusión ante los virajes políticos que experimenta la región de América Latina. A pesar de los discursos oficiales, es posible identificar que no existe un interés o beneficio económico en la convergencia de ambos bloques, incluso con la existencia de diálogos formales como el Plan de Puerto Vallarta. Los hechos señalan que la propuesta responde más a intereses de actores políticos particulares que buscan cumplir sus objetivos de gobierno.
As moradas da alma na perspectiva fenomenológica de Edith Stein | The mansions of the soul from Edith Stein’s phenomenological perspective
Authors: Peretti Clélia , Isatto Parise Maria Cecilia
Published: December 2020

O artigo apresenta a análise fenomenológica de Edith Stein do “Castelo Interior” de Teresa D’Ávila, Apêndice I, da obra “Ser finito e ser eterno”. Stein aplica o método fenomenológico no estudo das moradas da alma e analisa o caminho espiritual da Santa como um meio pelo qual as suas características naturais são direcionadas e potencializadas pela graça divina. Teresa utiliza a metáfora do castelo, com sete moradas: autoconhecimento, escuta e decisão, presença real de Deus, oração de quietude, oração de união (êxtase), enamoramento espiritual e matrimônio místico. Ela descreve pedagogicamente o caminho da alma no encontro com Deus e, após apresentar a descrição de Teresa, aponta semelhanças com a investigação fenomenológica da alma de Alexandre Pfänder. Além disso, demonstra alguns elementos teóricos que auxiliam na compreensão do núcleo da alma e de sua tendência a se desenvolver de forma livre e individual. Com Pfänder, compreende que o conhecimento da essência da alma é uma outra porta possível para se entrar na alma humana, além da oração. Assim, Stein mostra, na análise das moradas de Teresa, a estrutura ôntica da alma humana e a possibilidade de identificar a sua interioridade. A alma é o lugar da união mística, a Trindade, pela qual é possível aceder a Cristo, quando se está “em” Cristo. Encontra-se, assim, na fenomenologia de Stein, uma relação entre teologia e antropologia filosófica, entre o divino e o humano. Essa pesquisa aponta para um aprofundamento da experiência mística como experiência prática, kenótica e agápica
