Investigation of coupling effect between a unidirectional air waveguide and two cavities with one-way rotating state
Authors: Yongfeng Gao  , Liu He  , Zhen Jiang  , Jun Zhou  , Yuejia Shi  , Wenfang Bai
Published: May 2020

In the paper we present an implementation of resonance coupling between a unidirectional air waveguide and two cavities with one-way rotating state in a two-dimensional dielectric photonic crystal and a magneto-optical photonic crystal. We theoretically calculate the dispersion curves of the line defect waveguide and the dispersion curves of waveguide-cavity interaction, respectively. Numerical simulations show that, via waveguide-cavity coupling, a series of interesting resonance phenomena can be generated in the system. By modifying direction of the applied external magnetic field, storing and discharging of photonic energy can be realized. Our work may provide a practical and useful guidance for optical communications.
All optical binary ASK demodulator using photonic crystal based nonlinear ring resonator
Authors: Narimanzadeh Mahsa , Andalib Alireza
Published: May 2020

In this paper we will propose and design an all optical amplitude shift keying demodulator using a photonic crystal based nonlinear ring resonator. The proposed structure will be designed such that it can generate digital 0 and 1 based on the amplitude of the input signal. The working mechanism is based on controlling the optical behavior of the resonant ring using optical intensity. The proposed structure was simulated using plane wave expansion and finite difference time domain methods. The simulation results show that the rise and fall times for the proposed structure are 0.5 and 0.1 ps, respectively.

Authors: Jaglarz Janusz , Wyszyński Dominik , Lach Michał , Mikuła Janusz , Duraj Ryszard
Published: May 2020

The presented work describes the method of measuring surface topography with application of BRDF (bidirectional reflectance distribution function), ellipsometry and spectrophotometry. This non-contact method enables measurement and analysis of large area surfaces, such as plasters and facades. A standard method of topography analysis does not describe sufficiently all of the interesting features. The visual aspect of the surface evaluation is very important from the functional and utilitarian point of view. The proposed methods of surface analysis enable not only the quantitative evaluation but also indirectly the qualitative properties (visual aspects).
High Convergence Order Q-Step Methods for Solving Equations and Systems of Equations
Authors: Ioannis K. Argyros  , George Santhosh
Published: May 2020

The local convergence analysis of iterative methods is important since it demonstrates the degree of diffculty for choosing initial points. In the present study, we introduce generalized multi-step high order methods for solving nonlinear equations. The local convergence analysis is given using hypotheses only on the first derivative which actually appears in the methods in contrast to earlier works using hypotheses on higher order derivatives. This way we extend the applicability of these methods. The analysis includes computable radius of convergence as well as error bounds based on Lipschitz-type conditions not given in earlier studies. Numerical examples conclude this study.
,,Die Welt ist einmal, wie sie ist“. Literarische Konzeptionen gesellschaftlicher Ordnung und individueller Liebe in Fontanes Romanen1
Authors: Tafazoli Hamid
Published: May 2020

Der Beschluss des deutschen Bundestags über die ,,Ehe für alle“2 vom 30. Juni 2017 löste eine Reihe von Diskussionen über die Ehe als das gesetzlich geregelte Zusammenleben aus. Im Zentrum der Debatten stand nicht die Form, sondern die Normierung
der Ehe. Hierfür grundlegend ist der Artikel 6 des bundesrepublikanischen Grundgesetzes, der die Ehe und Familie unter den besonderen Schutz der staatlichen Ordnung stellt und erlaubt, Ehe und Familie als Lebensgemeinschaft im Sinne einer personellen Exklusivität zu begreifen. In
seiner Auslegung wird zum einen angemerkt, er enthalte keine Definition der Ehe3 und zum anderen, der Schutz und die Institutionsgarantie der Ehe stünden ,,gesetzlichen Reglungen zum Schutz eheähnlicher oder gleichgeschlechtlicher Lebensgemeinschaften nicht schlechthin“4
entgegen. Dem Beschluss des deutschen Bundestags folgten politische und kirchliche Kontroversen, zu denen die Öffentlichkeit je nach ihrer Fassung Position bezog. Politisch wurde er als ,,Ankunft in der Gegenwart“ bezeichnet.5 Auch die Evangelische Kirche in Deutschland
äußerte keine Einwände; die katholische Amtskirche hingegen zeigte starke Vorbehalte: Ihr gelte die Ehe nämlich als die Lebens- und Liebesgemeinschaft von Mann und Frau.6 Die Kontroversen spiegeln ein Paradoxon wider: Die Formen eines partnerschaftlichen Zusammenlebens
lassen sich zwar einer politischen und religiösen Norm unterziehen, legen aber offen, dass solch eine Norm auch das Potential besitzt, sich selbst in Frage zu stellen. Norm und Devianz gehen so Hand in Hand.
Bilder vom Glück. Mirko Bonnés Roman Lichter als der Tag
Authors: Vollmer Hartmut
Published: May 2020

Ein großes Potenzial, eine besondere Qualität der Literatur ist es, alternative ,Wirklichkeiten‘ und Utopien zu entwerfen, Vorstellungen des Glücks, Bilder der ,verlorenen Zeit‘ und der Sehnsucht zu projizieren. – In seinem 2017 erschienenen
Roman Lichter als der Tag unternimmt Mirko Bonné den Versuch, das verlorene Glück des Lebens und der Liebe erzählerisch zu gestalten und zu bewahren. Raimund Merz, der Protagonist des Buches, Anfang fünfzig, Redaktionsangestellter der Hamburger Zeitung Der Tag,
verheiratet mit einer Kieferchirurgin und Vater zweier Töchter, ist in ein Leben geraten, das er immer stärker als verfehlt und verlogen empfindet und erkennt. Wirkt diese Lebenssituation und Disposition der Romanhandlung auf den ersten Blick allzu bekannt, vielleicht gar klischeehaft,
so gelingt es Bonné, eine typisch erscheinende Midlife-Crisis individuell und unverwechselbar: kunstvoll zu erzählen. Dies soll im Folgenden am Titelmotiv des Romans – das einem Vers des Barockdichters Andreas Gryphius entlehnt ist1 –, einem sprachabgekehrten
Sehnsuchtsbild, das zugleich die Macht der Kunst als eine ,Wirklichkeitskorrektur‘ beweist, gezeigt werden.

Technological, Organizational and Environmental Framework for Digital Transformation in South African Financial Service Providers
Authors: Modiba Michael Makgale , Kekwaletswe Ray M
Published: May 2020

This paper addresses technological, organizational and environmental contexts as experienced within South African Financial Service Providers, with respect to digital transformation. Although digital transformation is well studied, the research problem is that literature inadequately addresses how these three contexts manifest and play a role as financial service providers transform to digital business. Informed by interpretivist philosophy stance and case study strategy, this paper shows how digital transformation is enabled or inhibited by contextual influences. The paper argues that digital transformation ought to manifest cognizant of the context in which the financial service provider finds itself. To this point, the paper conceptualises a framework that may help in the digital business transformation.
Gamma-Ray Burst Afterglows: Time-varying Extinction, Polarization, and Colors due to Rotational Disruption of Dust Grains
Authors: Hoang Thiem , Giang Nguyen Chau , Tram Le Ngoc
Published: May 2020

Prompt optical emission of gamma-ray bursts (GRBs) is known to have important effects on the surrounding environment. In this paper, we study rotational disruption and alignment of dust grains by radiative torques (RATs) induced by GRB afterglows and predict their signatures on the observational properties. We first show that large grains (size >0.1 μm) within a distance d < 40 pc from the source can be disrupted into smaller grains by the RAdiative Torque Disruption (RATD) mechanism. We then model the extinction curve of GRB afterglows and find that optical-near-infrared extinction decreases, and ultraviolet (UV) extinction increases due to the enhancement of small grains. The total-to-selective visual extinction ratio, R

V
, is found to decrease from the standard value of ∼3.1 to ∼1.5 after disruption time t
disr ≲ 104 s. Next, we study grain alignment by RATs induced by GRB afterglows and model the wavelength-dependence polarization produced by grains aligned with magnetic fields. We find that optical-NIR polarization degree first increases due to enhanced alignment of small grains and then decreases when RATD begins. The maximum polarization wavelength, λ
max, decreases rapidly from the standard value of ∼0.55 μm to ∼0.15 μm over alignment time of t
align ≲ 30 s due to enhanced alignment of small grains. Our theoretical predictions can explain various observational properties of GRB afterglows, including steep extinction curves, time-variability of colors, and optical rebrightening of GRB afterglows.
Coupling between the Magnetospheric Dipolarization Front and the Earth’s Ionosphere by Ultralow-frequency Waves

Published: May 2020

Magnetosphere–ionosphere coupling is representative of a class of astrophysical problems involving the interaction between very different plasma regimes that are connected by magnetic fields. It is a major issue of the planet’s (e.g., Earth, Jupiter, Saturn) system how the magnetospheric plasma is coupled to the planet’s ionosphere/atmosphere. Due to their roles on energy transport and conversion in the terrestrial magnetosphere, dipolarization fronts (DFs) in the magnetotail have been intensively studied. While the energy may also be transported toward the ionosphere during the magnetosphere–ionosphere coupling, the coupling processes during DF events remain unclear. Using high-quality MMS and Swarm measurements, we present new conjugated observations of ultralow-frequency waves associated with the DF in the magnetotail and multiscale field-aligned currents (FACs) in the ionosphere. The tail large-amplitude low-frequency magnetic disturbances and associated FACs were found connected with a pair of ionospheric FACs near the magnetic footprints of MMS. The earthward field-aligned Poynting flux of low-frequency waves reveals the energy transport from the DF toward the ionosphere. Meanwhile, small-scale and highly temporal ionospheric FACs suggest that the magnetotail shear Alfvén waves may evolve into kinetic Alfvén waves during the coupling processes. This finding implies that a very localized dynamic process (e.g., DFs in the terrestrial magnetotail) in the magnetosphere could couple the ionosphere with Alfvén waves.

Rediscovery of four narrow endemic Didymocarpus species (Gesneriaceae) from Mizoram, India, with revised species descriptions and lectotypifications
Authors: Prasanna Naibi Shrungeshwara , Gowda Vinita
Published: May 2020

Here we report the rediscovery of four endemic gesneriads from the state of Mizoram, India, after a span of 86 to 90 years since their last collection. The four species belong to the genus Didymocarpus Wall. and they are: D. adenocarpus, D. lineicapsa, D. parryorum, and D. wengeri. We present revised morphological descriptions, photographs, and designate lectotypes for D. parryorum and D. wengeri. During our study we came across several discrepancies between morphological characters assigned to these four species in the protologue and morphological characters present (or absent) in the type specimens and in plants recollected by us. We list these discrepancies in a section titled ‘amendments to protologue’. Based on the high endemicity and critical conservation status of all the four rediscovered species, we suggest that floristic studies along with large-scale biogeographic studies should be prioritized in the Indo-Burmese region.

A Comparative Study of Machine Learning Methods for Automatic Classification of Academic and Vocational Guidance Questions
Authors: Zahour Omar , Benlahmar El Habib , Eddaouim Ahmed , Hourrane Oumaima
Published: May 2020

Academic and vocational guidance is a particularly important issue today, as it strongly determines the chances of successful integration into the labor market, which has become increasingly difficult. Families have understood this because they are interested, often with concern, in the orientation of their child. In this context, it is very important to consider the interests, trades, skills, and personality of each student to make the right decision and build a strong career path. This paper deals with the problematic of educational and vocational guidance by providing a comparative study of the results of four machine-learning algorithms. The algorithms we used are for the automatic classification of school orientation questions and four categories based on John L. Holland's Theory of RIASEC typology. The results of this study show that neural networks work better than the other three algorithms in terms of the automatic classification of these questions. In this sense, our model allows us to automatically generate questions in this domain. This model can serve practitioners and researchers in E-Orientation for further research because the algorithms give us good results.

Published: May 2020

This present work consists of studying the synthesis and the effect of Sn and Co content on the density and hardness of binary systems (Cu100-x-Snx, Cu100-x-Cox). In this work we have study the influence of the addition of tin and cobalt (X = 5, 10 and 12 % by weight) in the metastable domain. The hardness of the Cu-Sn and Cu-Co alloys becomes high with the increase of the content of these two additive elements, the compacting pressure and the sintering temperature and even the effect of these on the increase of the density in an almost linear way. The porosity rate is proportional to the compaction pressure. SEM observation shows that the dispersion and particle size of tin and cobalt in the copper matrix is ​​irregular.

Authors: Mathebula Vonani Clive , Saha Akshay Kumar
Published: May 2020

The use of Substation Communication Networks (SCN) in power distribution centres of thermal power plants for protection, control and monitoring is increasing as industry’s confidence grows in the application of the IEC-61850 based Substation Automation Systems (SAS). IEC-61508, which is the standard for functional safety, addresses Electrical/Electronic/Programmable Electronic (E/E/PE) safety based technologies in so far as safety lifecycle as well as reliability and verification of safety related systems are concerned. It follows therefore, that Substation Communication Networks (SCN), as well as associated substation equipment that forms part of the overall safety system should satisfy the requirements of functional safety standard IEC-61508. In this paper, Substation Automation System standard (SAS) IEC-61850, Substation Communication Networks (SCNs) as well as dependability evaluation methods are reviewed and discussed.

Published: May 2020

Background Delirium after cardiac surgery is a common complication in cardiovascular intensive care units. The prevalence of delirium and its likely risk factors have not previously been explored in a single sample of postoperative cardiac patients in an intensive care unit.

Objective To compare a variety of characteristics in patients with and without delirium and to identify risk factors associated with delirium in patients hospitalized in an intensive care unit after cardiac surgery.

Methods A retrospective chart review was used to collect data on 288 patients who had open heart surgery during the period 2004 to 2005 at Chang Gung Memorial Hospital in northern Taiwan. A researcher-designed checklist of 52 patient-related risk factors for delirium was used to collect preoperative, intra-operative, and postoperative data. All patients were assessed by psychiatrists, and delirium was diagnosed according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. Data were analyzed via univariate analysis and multivariate logistic regression.

Results The prevalence of postoperative delirium was 41.7%. Patients with and without delirium differed significantly on 29 variables. Four postoperative factors, hematocrit less than 30%, cardiogenic shock, hypoalbuminemia, and acute infection, were significant, independent predictors of postoperative delirium.

Conclusions The results of this study can be used to develop a revised checklist of 29 preoperative, intraoperative, and postoperative risk factors for delirium, with special attention to the 4 predictive postoperative factors. Use of such a checklist may facilitate the ability to prevent or detect delirium early and provide suitable treatment.

Published: May 2020

Objective:

A cross-sectional study was undertaken to assess the prevalence of morbidities in communities residing at variable distances from the closed down insecticide manufacturing plant premises of Union Carbide India Limited (UCIL), Bhopal, India and to determine association of morbidities, if any, with their drinking water usage pattern and distance of localities from the UCIL plant.

Materials and Methods:

A total of 10,827 individuals belonging to 2,184 families, residing within 0-1 km (Stratum I) and 2.5-5.0 km (Stratum II) radial distances from UCIL plant were surveyed and 9,306 of them (86%) were clinically examined. Data were analyzed to examine the association between the groups of morbidities, likely due to biological and chemical water contamination, and the distance of locality from the UCIL plant. Multiple logistic regression was used to explore the risk factors for morbidities.

Results:

Nearly similar prevalence (25.3% in stratum I, 25.8% in stratum II) and the trend of all-cause morbidities were recorded in the two strata. While morbidities related to gastrointestinal tract system (P < 0.05), auditory system (P < 0.01), neoplasm/cancers (P < 0.01) and congenital anomalies (P < 0.01) were significantly higher in stratum I, the prevalence of hypertension (6.4% stratum II, 4.7% stratum I; P < 0.01) and diabetes mellitus (3.4% stratum II, 2.0% stratum I; P < 0.001) was found significantly higher in stratum II. No association (P > 0.05) was observed between the prevalence of morbidities, likely due to the consumption of biologically or chemically contaminated drinking water, and the distance of locality/stratum from the UCIL plant.

Discussion and Conclusion:

By and large similar pattern of morbidities were recorded in the two strata suggesting that the communities, irrespective of the distance of their residences from UCIL plant or sources of their drinking water, are equally vulnerable to various morbidities.

3. Aproximaciones teóricas sobre el proceso y la acción de resolución de problema
Authors: Minotta-Valencia (Universidad de Antioquia) Carlos
Published: May 2020

El presente artículo  aborda el campo de la resolución de problemas a partir de tres perspectivas teóricas. Siendo la primera, la corriente asociacionista, según la cual, la solución a un problema es explicable por medio de asociaciones de complejidad creciente del tipo estimulo-respuesta, que a su vez obedecen a las leyes del aprendizaje: del ejercicio y el efecto. La segunda es la Gestáltica: postula que la solución a un problema, no deriva de asociaciones mecánicas sino de la reorganización del campo perceptivo y de la comprensión de la configuración específica que adoptan los elementos de una totalidad significativa y coherente. Finalmente, se expone la teoría del significado: de acuerdo a ella, la solución a un problema, deviene por descubrimiento significativo; nueva información se relaciona con la experiencia pasada del sujeto, modificándose con ello la estructura cognitiva.

Para el tratamiento se seleccionó un testigo de la vitro-planta el cual tuvo un medio tradicional, mientras que 4 grupos fueron sometidos a diferentes concentraciones de los medios sustitutos para el Agar-Agar. Se espera que esta investigación permita generar medios alternos que contribuyan a la reducción de la utilización del Agar en los medios de cultivos in vitro.
2.Praxis cultural del grupo Luango de Venezuela. Aporte desde la Pedagogía Crítica de Paulo Freire
Authors: Mieres (UNEY) Rosana Ines
Published: May 2020

Reflexionar acerca de la pedagogía crítica liberadora propuesta por Paulo Freire ha constituido, en las últimas décadas, un importante aporte en la manera de concebir la educación y el desarrollo del ser humano. En esta investigación que aún está en ejecución se pretende como objetivo general, interpretar la praxis cultural del grupo Luango de Venezuela y su aporte desde la pedagogía crítica de Freire. El tema es abordado desde el paradigma cualitativo, con una visión fenomenológica y asumiendo como válida para desarrollar esa interpretación, las experiencias de los actores protagónicos de esa agrupación musical.  En el contexto interpretativo,LUANGO y su praxis musical emergen como un esfuerzo para fortalecer la relación educación y cultura, al tiempo que pone en escena el patrimonio musical del país y recrea el método de trabajo de la convivencia con los creadores populares legitimando una concepción menos elitista y efectivamente liberadora de la cultura.

Los informantes clave fueron docentes de la institución mencionada, hasta que la información se consideró saturada. Ésta fue recolectada a través de la entrevista a profundidad. De ahí surgieron los hallazgos que permitieron develar la percepción de una inquietud por parte del equipo docente sobre la gestión gerencial del director, puesto que consideran necesario e importante que se fortalezcan los procesos gerenciales en pro del logro de resultados relacionados con la eficacia y eficiencia, porque se interpreta que existen ciertas debilidades en la praxis gerencial que inciden de manera negativa en el alcance de la tan ansiada calidad educativa.

Reforma Protestante: uma caminhada de 500 anos
Authors: Burmann Claudir
Published: May 2020

Resumo: A Reforma Protestante impactou o Cristianismo ocidental com umadivisão, cuja repercussão tem perpassado diversos âmbitos ao longo dos últimos500 anos. Como seria o Cristianismo se a Reforma Protestante não tivesseocorrido? Evidentemente, não há como responder. Certo é que a Reforma Protestantefoi, de alguma maneira, favorecida por fatores conjunturais do séculoXVI, que ampliaram sua repercussão. Tais fatores fizeram com que o protestoinicial de Martim Lutero através de 95 teses acerca da venda de indulgênciastivesse um alcance não imaginado. A partir dali, foi-se consolidando um novomodo de compreender o agir de Deus. Ao mesmo tempo, uma nova forma decompreender o próprio ser humano se afirmou. Embora ao longo de quatroséculos tenha havido controvérsias, embates e combates mútuos, atualmentebusca-se uma nova caminhada entre as Igrejas Luteranas e a Igreja CatólicaRomana. A celebração dos 500 anos da Reforma tem-se revelado como oportunidadeúnica para a promoção da unidade cristã.Palavras-chave: Martim Lutero. 95 teses.

Ofcourse, there is no answer to this. It is true that the Protestant Reformation wassomehow favored by situational factors of the sixteenth century, that amplified itsimpact. These factors have caused the initial protest of Martin Luther through 95theses about the sale of indulgences to have had an unimaginable range. Fromthen, it has consolidated a new way of understanding the action of God. At the sametime, a new way of understanding the human being was asserted. Although duringover four centuries there have been disputes, conflicts and mutual fighting, nowone seeks for a new walk between Lutheran Churches and the Roman CatholicChurch. The celebration of the 500th anniversary of the Reformation has beenrevealed as an unique opportunity for the promotion of Christian unity.Keywords: Martin Luther. 95 theses. Protestant Reformation.

The Social Position of Women in Cities in the USA During the 1960s-1980s
Authors: Koroleva Vlada V.
Published: May 2020

The article is dedicated to the problem of the position of women in cities and to creation and formation of “women’s spaces” in the United States in 1960-1980.

Following the development of the second wave of feminism, we focused the attention not only on the movement for civil rights itself but also on the activities of organizations and women who were trying to improve the living conditions of female citizens.

Prisoners in their homes, women have always been associated more with the suburbs than with the cities themselves. They were never seen as citizens, but rather as rare guests in this urban space.

In order to make cities more women-friendly, feminists began to create exclusive women’s spaces that would help women not only get out from their house-arrest but also solve difficult life situations. Shelters, women’s health centers, women’s libraries, book clubs and kindergartens – all of these new spaces helped an American woman move out of the alienation spaces of their houses and gain new opportunities for self-development.
