Combinando Impresión 3D y electrónica como estrategia para mejorar la experiencia de aprendizaje
Authors: Suardíaz Muro Juan , Pérez Gomáriz Mario , Cabrera Lozoya Andrés , Ove Do Carmo Trolle René
Published: November 2020

En la actualidad, la impresión 3D se ha convertido en una tecnología que ha creado un nuevo paradigma de comunidades de aprendizaje, constituyendo una cultura o subcultura contemporánea, denominada coloquialmente como “cultura maker”, la cual puede considerarse como una extensión de la cultura DIY (Do It Yourself o hágalo usted mismo). Se trata de una nueva cultura basada en la tecnología y en el uso de herramientas que ha tenido gran aceptación en campos diversos como la ingeniería, medicina, arquitectura y artesanía. El presente artículo muestra una experiencia de integración de aprendizaje de Impresión 3D con electrónica dentro del currículo de la titulación de Ingeniería Industrial, especialidad en Mecánica. Para ello se ha utilizado la metodología de Aprendizaje Basado en Servicio. Se ha localizado una posible necesidad social y, a partir de esta necesidad se ha propuesto el diseño de una solución por parte de los alumnos. El ejemplo seleccionado ha sido el desarrollo de una mano robótica capaz de comunicarse mediante el lenguaje de signos. Con este trabajo los alumnos han reforzado sus conocimientos de modelado 3D utilizando el software de modelado Solid Works, así como sus conocimientos de electrónica, teniendo que desarrollar el sistema de control de los motores de las articulaciones de la mano usando un sistema basado en el popular microcontrolador Arduino.
La virtut de la fortalesa als sirventesos morals de Pere March
Authors: I Ferrer Lluís Ramon
Published: November 2020

Aquest article és una lectura conjunta i complementària dels poemes I, II i III de Pere March. S’hi ha observat un programa ascètic basat en la virtut de la fortalesa i en les virtuts que li són annexes: magnanimitat, magniicència, paciència i perseverança. Aquestes virtuts són presentades amb exempla que il·lustren els vicis que se’ls oposen i que, sempre que ha estat possible, s’han relacionat amb el Communiloquium o Summa de Col·lacions de Joan de Gal·les, llibre present a la biblioteca del poeta.This paper is a joint and complementary reading of poems I, II and III by Pere March. An ascetic program has been observed based on the virtue of fortitude and its annexed virtues: magnanimity, magniicence, patience and perseverance. These virtues are presented, by contrast, with exampla that illustrates the vices that oppose them and that, whenever possible, have been related to the Communiloquium or Summa of Collations of John of Wales book present in the poet’s library.

Pernambuco “feminina”, mulher fêmea, sim! A mulher na mazurca do Alto do Moura: culturas, vivências e músicas
Authors:   Universidade Federal da Paraíba - UFPB, Santos Marília Paula dos
Published: November 2020

A subordinação da mulher é um fenômeno universal, milenar, e é a primeira forma de opressão da humanidade (Ana COSTA; Cecília SARDENBERG, 2008). Trabalhos que abordam a relação entre mulher e música, ou música e gênero, ainda precisam emergir mais, embora perceba-se uma crescente no campo nos últimos anos. Este artigo apresenta a presença das mulheres (como criadoras, performers, musas, mestras) na Mazurca Pé Quente do Alto do Moura, apontando para a importância dos contextos em que a música está inserida, assim como a relevância de trabalhos que falam sobre mulher no âmbito musical. Foram realizadas entrevistas, observações e conversas informais com as/os integrantes da mazurca. A maior parte dos dados foi coletada para o “Inventário do Ofício dos Artesãos e Artesãs do Barro do Alto do Moura – Caruaru-PE”.

Authors: Muñoz Cañavate Antonio , Cordero-González Alejandro , Tena-Mateos María José
Published: November 2020

En este trabajo se presentan los resultados de un estudio destinado a conocer las opiniones de los administradores de las listas de distribución de correo electrónico gestionadas por RedIRIS. El estudio ha tenido tres objetivos: conocer el nivel de satisfacción que tiene cada administrador con diferentes medios electrónicos para recibir información en su trabajo diario, y especialmente con las listas de distribución; conocer la evolución de sus listas respecto al número de mensajes y suscriptores; conocer el nivel de acuerdo o desacuerdo sobre las listas de distribución como medio de compartición del conocimiento y de canal para el aprendizaje.  Los administradores encuestados valoran las listas como la mejor aplicación como método para compartir y difundir información entre profesionales y académicos. Aunque no todas las listas gozan de la misma fortaleza, siguen siendo utilizadas por los usuarios. Y sirve de herramienta para la gestión del conocimiento, y de  utilidad para la formación y el aprendizaje.

This paper presents the results of a study aimed at learning the opinions of the administrators of email distribution lists managed by RedIRIS.  The study had three objectives: to determine each administrator's level of satisfaction with the different electronic media they themselves use to get information for their daily work, especially with distribution lists; to determine how their lists have evolved in regard to the number of messages and subscribers; and to determine their level of agreement or disagreement with distribution lists being a means of knowledge sharing and a channel for learning.  The surveyed administrators value the lists as the best application for sharing and disseminating information among professionals and academics.  Although not all lists enjoy the same strength, they are still being used.  And they serve as a tool for knowledge management, and are useful for training and learning.
El tema del río Nilo en el teatro de Esquilo
Authors: Espinós Jesús Ángel
Published: November 2020

Esquilo es un autor especialmente atento a los aspectos geográficos, como se puede apreciar en su interés por el río Nilo, fundamentalmente en Las suplicantes , obra donde la presencia de Egipto es continua. A lo largo del artículo, hemos analizado la importancia del río Nilo,de su paisaje y de su peculiar comportamiento en las tragedias de Esquilo y en el imaginario griego del s. V a. C.

Aeschylus is an author especially concerned with geographical aspects, as it can be seen in his interest on the Nile River, mainly in The Suppliants, a work where the presence of Egypt is ubiquitous. In this article, we have analysed the importance of the Nile River, its landscape and its pecul ar behaviour in Aeschylus’ tragedies and in the Greek imaginary of the 5th century BC.

Las metamorfosis de los diferentes personajes mitológicos forman parte indispensable del acervo cultural de los griegos antiguos desde los primeros inicios de su literatura. Este trabajo pretende ofrecer un análisis sobre la temática y terminología, empleada por los epigramatistas helenísticos e imperiales para describir los procesos de metamorfosis, bien de seres mortales o divinos, en las composiciones de la Antología Griega. Este estudio permite replantearnos la riqueza y diversidad de formas léxicas y construcciones sintácticas, reducidas por el testimonio de los lexicógrafos, y a hallar indicios sobre la existencia de una lexicografía propia de estos contextos literarios.
Consumer Knowledge and Participation in the Sharing Economy
Authors: Jeong Yunjik , Kim Kee Ok
Published: November 2020

This study examines the level of consumer knowledge regarding the concept and characteristics of the sharing economy along with the role of the three economic players in the sharing economy. This study develops scales for measuring a consumer’s knowledge level and the knowledge level using these scales as well as analyzes the impact of knowledge levels, socio-demographic variables, social capital, and knowledge sharing on participation in the sharing economy. The scales measuring the level of knowledge in the sharing economy were composed of 22 questions for the concept, 30 questions for the characteristics, and 15 questions for the role of the economic parties. Consumer’s knowledge level regarding the concept and characteristics of the sharing economy and the role of the economic players was very low. In particular, the knowledge on the concept was insufficient. Women’s knowledge on the sharing economy showed higher scores than men. Consumers with higher scores in social capital and knowledge sharing showed higher scores of the knowledge level on the sharing economy than those behind in these two variables. A higher knowledge level of the sharing economy resulted in higher participation in the sharing economy. Issues and directions for future studies on the sharing economy were proposed.
Predictive Model of the Intent of Work-Family Multiple-Role Planning among Female University Students: Integration of Social Cognitive Career Theory and Theory of Planned Behavior
Authors: Kim Jieun , Park Mee Sok
Published: November 2020

This study presents work-family multiple-role planning by female university students as a new approach to work-life balance. Accordingly, this study examines university years as a key time frame during which students establish their career paths. This study integrates the social cognitive career theory and the planned behavior theory to design and evaluate a model that explains the work-family multiple-role planning process; in addition, it develops an optimal model to predict the intentions of female university students in work-family multiple-role planning. This study has conducted a structural survey with 500 female university students. After inspecting the data, the responses of 435 participants were used in the data analysis (SEM) with SPSS 21.0 and AMOS 21.0. The findings include the following. First, suitability of predictive model presents a satisfying fit. The major factors in this study’s model (parental support, subjective norms, attitudes toward multiple-role planning, career decision self-efficacy, and outcome expectations) are verified as direct and indirect predictors of the work-family multiple-role planning intent of female university students. Second, the strongest predictive factor for the work-family multiple-role planning intent is the social environment factor (subjective norms), indicating that the influence of social pressure on intent is relatively large. The predictive model formulated under this study’s integrated theoretical framework supplements existing research that focused on attitudes toward multiple-role planning as well as provides a more profound theoretical foundation on which work-family multiple-role planning behaviors can be better understood.
Evaluation of Dietary Life Instruction in Middle School Home Economics by Converging Habermas’s Three Systems of Action
Authors: Choi Seong-Youn
Published: November 2020

This study developed and implemented a teaching · learning process plan for Home Economics in middle school by converging Habermas’s three systems of action. It also examined the effect of the class through the evaluation of students and teachers who participated in the class. This study developed 10 sessions for a teaching and learning process plan by converging three systems of action and reconstructing learning elements related to ‘balanced meal plan’ and ‘food choice’ according to the practical action teaching model. After class, we surveyed the degree of help for students, analyzed the learning activity sheets, and analyzed the reflection journals of teachers to evaluate the effects of the class.
This class was found to be the most helpful in practicing the healthy dietary life of students, expanding their thoughts, understanding learning contents, and helping them change their lives. As a result of analyzing the learning activity sheet, students gained enlightenment by reflecting and evaluating their action through the class; in addition, changes in interest, awareness, and action appeared. Through the convergence of three systems of action, teachers who practiced the class criticized and realized the act that students were unconsciously accepted. In addition, it confirmed the possibility that students could change their lives, family and society by promoting optimal nutrition and health for a good life that pursues the best good.
Effects of Education and Mothers’ Perceptions regarding English Education on Preschoolers’ Interests in Learning English: A Comparison between General Kindergartens and English Immersion Institutes
Authors: Choi Naya , Park You-Me , Choi Jisu
Published: November 2020

This study investigated children’s interests in learning English, affected by educational activities in and out of institutes, and mothers’ perceptions regarding early childhood English education. We recruited, 253 mothers of 3- to 5-year-old children in either general kindergartens or English immersion institutes. They answered questions on socioeconomic status, perceived interest in English by their children, their perceptions regarding early childhood English education, and English education outside institutes. In addition, 42 English teachers provided information within institutes such as class time per week, teacher-pupil rate, and language use policy during class. The collected data were analyzed through SPSS 22 for frequency analysis, descriptive statistics, independent t-test, and hierarchical multiple regression analysis. The major findings are as follows. First, the two groups were in distinct learning environment. Second, mothers’ perceptions and outside-institute activities were significantly different between the two groups. Third, the English interests of children at both institutes were influenced by mothers’ worries and at-home English interactions. Fourth, education within institutes did not affect both group’s English interests. Fifth, private education and socioeconomic status did not affect both group’s English interests. Lastly, only the children’s interests in English immersion institutes were affected by gender and mother’s perceived necessities. Focusing children’s interests, this study helps in understanding young children’s affective aspects regarding learning English. The findings are expected to be a guideline for each home and institute to increase children’s interest in learning English.
SPECTRAL MEMORIES: AESTHETIC RESPONSES TO THE FINANCIAL CRASH IN ICELAND 2008
Authors: Knútsdóttir Vera
Published: November 2020

In October 2008, one of the largest bank crashes in history struck Iceland, a country of three hundred and thirty five thousand inhab-itants. The aim of the article is to examine two cultural responses to the crash and the crisis that followed. More precisely, the aim is to analyse how the creation of the haunted house in I Remember You, a crash-horror story by crime writer Yrsa Sigurðardóttir, as well as the spectral half-built houses portrayed by visual artist Guðjón Ketilsson refer quite directly, yet spectrally, to the period. The spec-tral themes of the two works give the opportunity to discuss the moment following the crash as a moment of haunting—but who is haunted and by whom?
MONEY AS FRAME
Authors: Huber Nicholas
Published: November 2020

This essay responds to “Money as Art: The Form, the Material, and Capital” by the Marxist economist Costas Lapavitsas with refer-ence to the triple manifestation of crisis in the United States dur-ing the spring months of 2020. By triangulating the role of money in the COVID-19 pandemic, the ensuing mass unemployment, and the historical nationwide revolt in response to the police mur-der of George Floyd predicated on a counterfeit twenty-dollar bill, Nicholas Huber makes a three-part claim. First, that acceptance of the Marxist theory of fetishism forecloses the possibility of conceiv-ing of capitalist money as art in the sense developed by Lapavitsas, insofar as the latter tends toward transhistorical concepts of both art and money. Following from this, any aesthetic function of mon-ey in the capitalist mode of production is inseparable from its total social function; that is, capitalist money is at once an economic, political, cultural, and aesthetic mediation unlike any other. Finally, Huber draws on Louis Marin’s typology of the frame in correspond-ence with Erik Olin Wright’s integrated class analytic framework to argue that the question of whether money is art or not leads us to a dead end. Huber suggests that a crisis such as the one unfolding in 2020 raises instead the more challenging question of what social system must come into being, such that a theory of capitalist money as art becomes intelligible.
Mass grave exhumations as patriotic retreat
Authors: Hristova Marije , Żychlińska Monika
Published: November 2020

Between 2012 and 2017, at the Ł-section of Warsaw’s Powązki Military Cemetery, or ‘Łączka’, the Polish Institute of National Remembrance exhumed a mass grave containing the remains of post-war anti-communist resistance fighters. Being referred to as the ‘cursed soldiers’, these fighters have become key figures in post-2015 Polish memory politics. In this article we focus on the role of the volunteers at these exhumations in the production of the ‘cursed soldiers’ memory. Following the idea of community archaeology as a civil society-building practice, the observed processes of sacralisation and militarisation show how the exhumations create a community of memory that promotes the core values of the currently governing national-conservative PiS party. We found that tropes related to forensic research and typically identified with cosmopolitan memory paradigms are used within a generally nationalist and antagonistic memory framework.
Structural violence and the nature of cemetery-based skeletal reference collections
Authors: Vanderbyl Greer , Albanese John , Cardoso Hugo F. V.
Published: November 2020

The sourcing of cadavers for North American skeletal reference collections occurred immediately after death and targeted the poor and marginalised. In Europe, collections sourced bodies that were buried and unclaimed after some time in cemeteries with no perpetual care mandate, and may have also targeted the underprivileged. The relationship between socio-economic status (SES) and abandonment was examined in a sample of unclaimed remains (603 adults and 98 children) collected from cemeteries in the city of Lisbon, Portugal, that were incorporated in a collection. Results demonstrate that low SES individuals are not more likely to be abandoned nor to be incorporated in the collection than higher SES individuals. Furthermore, historical data indicate that the poorest were not incorporated into the collection, because of burial practices. Although the accumulation of collections in North America was facilitated by structural violence that targeted the poor and marginalised, this phenomenon seems largely absent in the Lisbon collection.
The relationship between fearful facial expressions valences and resting-state SW/FW ratio

Published: November 2020

Fearful facial expressions are considered dangerous and may lead to potential punishment and may be associated with behavioral inhibitions. In the present study, we examined the possible associations between the resting-state slow-wave and fast-wave ratio (SW/FW) and the valence of fearful faces. Previous studies have shown the role of SW/FW in approach-driven motivation and reward-seeking behavior. The resting-state EEG of 75 high school and undergraduate students were recorded while they were performing the valence judgment task. The results indicated a positive correlation between the global score of SW/FW and the valence of fearful faces. Moreover, multiple regression analyses indicated SW/FW in the left medial frontal as the best predictor of the valence of fearful faces. The present study confirms the previous findings underlying SW/FW mechanisms in the motivational system, including a prediction of increased SW/FW in elevated reward sensitivity and decreased SW/FW in elevated punishment sensitivity.
THE FERROMAGNETIC AND ANTIFERROMAGNETIC KINEMATIC INTERACTIONS AT LOW TEMPERATURE
Authors: TAU YUNG  ,   复旦大学
Published: November 2020

A new method is developed to treat the ferromagnetic and the antiferromagnetic kinematic interactions. All the kinematic interactions can be represented by means of every order correlation functions. It is shown that the ferromagnetic system (s=1/2) does not involve the T3-term at low temperature. For the antiferromagnetic system, we find that the kinematic interaction is large than the dynamic interaction even at low temperature. Our theory is good for all spin values s as well.
THEORY OF THE DYNAMICAL JAHN-TELLER EFFECT IN STRONG COUPLING
Authors: FANG LI-ZHI  , OU ZHI  ,   中国科学技术大学
Published: November 2020

The dynamical Jahn-Teller effect has been treated in the case of strong coupling for which the static distortional energy of electrons is larger than the energy of a typical vibrational quantum. A perturbation method which applies to strong coupling is developed. The eigenfunction and eigenvalue are expanded as power series of the ratio of the vibrational quantum to the static distortional energy. We have dealt explicitly with the Jahn-Teller effect of the Г8 state of an Oh point group; the energy levels of electronic-vibration system are obtained. The characteristics of strong coupling as compared with weak coupling are: 1) although no static distortion actually appears, the degeneracy and frequency spectra of vibrational modes are changed; 2) the collective modes of electronic-vibration system will appear, if the vibrational modes coupled to the electrons are "tuned". The theory is employed to interpret the experimental results obtained by Weinstock et al. on TcF6 and ReF6 from the infra-red and Raman spectra.
MINORITY CARRIER LIFETIME IN SILICON CARBIDE BY THE ELECTROLUMINESCENCE METHOD
Authors: YUI SHOU-DUNG  , WOO DAU-WEI  , TON FU-DI  , TAM HOA-YEN  ,   中国科学院
Published: November 2020

A method for measuring the minority carrier lifetime in silicon carbide semiconductor by the injection electroluminescence at point contacts is presented. The principles involved and measuring equipment used are described. Experiments on some important factors, such as resonance disturbance, electrical properties and electroluminescence characteristics of the point contacts, have been performed. Some feasible precautions that must be taken in order to avoid resonance disturbance and contact by-passing and to control rectification ratios are described. It is shown that in order to ensure reliability of experimental results, a knowledge of the electroluminescence characteristics of the samples should be required before measuring. By means of this method, the minority carrier lifetimes for some silicon carbide single crystals have been measured, and for most crystals these values are found to be smaller than 4.2×10-9 sec.
Research progress on electrochemical properties of electrolyte and its interphase
Authors: Xing Li-Dan , Xie Qi-Ming , Li Wei-Shan ,   School of Chemistry, South China Normal University, Guangzhou 510006, China
Published: November 2020

Electrolyte not only plays the role of conducting ions in lithium ion battery, but also the thin layer electrolyte formed on the electrode surface determines the stability of electrode/electrolyte interface to a large extent, thus affecting the cycling stability, rate performance and safety of the battery. The successful commercialization and widespread application of lithium ion battery is closely related to the solid electrolyte interface film formed by the decomposition of electrolyte on the electrode surface. In this paper, the electrochemical stability and decomposition mechanism of the interface electrolyte are briefly reviewed, aiming to draw more scientists' attention to the electrolyte and its interfacial properties.

Authors: García-González Herminio , Boneva Iovka , Staworko Sławek , Labra-Gayo José Emilio , Cueva Lovelle Juan Manuel
Published: November 2020

Integration of heterogeneous data sources in a single representation is an active field with many different tools and techniques. In the case of text-based approaches—those that base the definition of the mappings and the integration on a DSL—there is a lack of usability studies. In this work we have conducted a usability experiment (n = 17) on three different languages: ShExML (our own language), YARRRML and SPARQL-Generate. Results show that ShExML users tend to perform better than those of YARRRML and SPARQL-Generate. This study sheds light on usability aspects of these languages design and remarks some aspects of improvement.
Determination of the reference genes for qRT-PCR normalization and expression levels of MAT genes under various conditions in Ulocladium
Authors: Ma Li-Guo , Geng Yun
Published: November 2020

The genus Ulocladium is thought to be strictly asexual. One of the possible reasons for the lack of sexuality in Ulocladium species is the absence of the stimulus of environmental factors. Sexual reproduction in ascomycetes is controlled by a specific region in the genome referred to as mating-type locus (MAT) that consists of two dissimilar DNA sequences in the mating partners, termed MAT1-1 and MAT1-2 idiomorphs. To identify the response of MAT loci to environmental conditions, the mRNA transcription level of MAT1-1-1 and MAT1-2-1 genes was tested using qRT-PCR under different temperatures (−20 °C, −10 °C, 0 °C, 10 °C, 20 °C, 30 °C and 40 °C), culture medias (CM, OA, HAY, PCA, PDA and V8), photoperiods (24 h light, 24 h dark, 12 h light/12 h dark, 10 h light/14 h dark and 8 h light/16 h dark), and CO2 concentrations (0.03%, 0.5%, 1%, 5%, 10%, 15% and 20%). For obtaining reliable results from qRT-PCR, the most stable internal control gene and optimal number of reference genes for normalization were determined under different treatments. The results showed that there is no universal internal control gene that is expressed at a constant level under different experimental treatments. In comparison to various incubation conditions, the relative expression levels of both MAT genes were significantly increased when fungal mycelia were grown on HAY culture media at 0–10 °C with a light/dark cycle, indicating that temperature, culture media, and light might be the key environmental factors for regulating the sexuality in Ulocladium. Moreover, MAT1-1-1 and MAT1-2-1 genes showed similar expression patterns under different treatments, suggesting that the two MAT genes might play an equally important role in the sexual evolutionary process.
The use of artificial substrate units to improve inventories of cryptic crustacean species on Caribbean coral reefs
Authors: Monroy-Velázquez Luz Verónica , Rodríguez-Martínez Rosa E. , Blanchon Paul , Alvarez Fernando
Published: November 2020

Motile cryptofauna inhabiting coral reefs are complex assemblages that utilize the space available among dead coral stands and the surrounding coral rubble substrate. They comprise a group of organisms largely overlooked in biodiversity estimates because they are hard to collect and identify, and their collection causes disturbance that is unsustainable in light of widespread reef degradation. Artificial substrate units (ASUs) provide a better sampling alternative and have the potential to enhance biodiversity estimates. The present study examines the effectiveness of ASUs made with defaunated coral rubble to estimate the diversity of motile cryptic crustaceans in the back-reef zone of the Puerto Morelos Reef National Park, Mexico. Species richness, Simpson’s diversity index, Shannon–Wiener index and the composition of assemblages were compared between ASUs and samples from the surrounding coral rubble substrate. A combined total of 2,740 specimens of 178 different species, belonging to five orders of Crustacea (Amphipoda, Cumacea, Isopoda, Tanaidacea and Decapoda) were collected. Species richness was higher in the surrounding coral rubble and Shannon–Wiener and Simpson indexes were higher in ASUs. Species composition differed between methods, with only 71 species being shared among sampling methods. Decapoda was more speciose in ASUs and Peracarids in the surrounding coral rubble. Combining the use of ASUs with surrounding rubble provided a better inventory of motile cryptic crustacean biodiversity, as 65% of the species were represented by one or two specimens.

Optic Nerve Glioma – A Rare Case Report
Authors: Dutta Udbuddha
Published: November 2020

An optic nerve glioma is a slow growing tumour which typically affects children. Malignant gliomas are rare and almost always occur in adult males with a very poor prognosis. It is a brain tumour that arises in or around the optic nerve, which connects the eye to the brain. We describe a case of a 5 year old boy with painless progressive enlargement of the left eye since the past 1 year. He also complained of a loss of vision in the left eye. The father had a history of Neurofibromatosis type 1. The child was clinically evaluated and required investigations were carried out. This was consistent with the diagnosis of optic nerve glioma. Early diagnosis is the key factor and an integrated approach should involve neurosurgeons, plastic surgeons, ophthalmologists and radiologists.
Latest Update in Glaucoma: The first approvals for Rho Kinase inhibitors
Authors: Bali Jatinder , Bali Ojasvini
Published: November 2020

Glaucoma, the leading cause of irreversible blindness, blinds causes irreversible blindness in 4.0 million people worldwide. In India the estimated number of glaucoma patients is 12 million which is one fifth of the global morbidity of glaucoma.1 Elevation of intraocular pressure (IOP) is the only proven modifiable risk factor for most forms of glaucoma. Different etiological mechanisms have been proposed for increased IOP. Aqueous humor (AH) drainage from conventional or trabecular and uveoscleral pathway is a proven cause in most glaucoma patients and especially so in primary open angle glaucoma. IOP reduction slows vision loss and remains the mainstay of treatment for all types of glaucoma. Rho kinase is a serine/threonine protein kinase. It is a downstream effector of Rho GTPase, a Ras superfamily GTPase. it has a role in the conventional path of aqueous drainage. Rho Kinase (ROCK) inhibitors Ripasudil, K-115 and Netarsudil, AR-13503 have recently been approved for ophthalmological use in therapy of glaucoma as IOP-lowering agents. This is a brief overview of the Rho Kinase (ROCK) inhibitors.

Authors: Sunandini G. P. , Suhasini K. , Devi I. Shakuntala
Published: November 2020

In the present paper an attempt has been made to examine the role of women in Andhra Pradesh Agriculture especially in natural resource management. The study focused on studying participation of women in crop management, wage discrimination, ownership, access to economic resources and economic decision making and natural resources management at micro level and macro level.  The study revealed that about 22% of cost of cultivation and 56% of the labour cost is incurred towards female labour accounting to Rs 3424 out of cost of cultivation Rs. 19725/ha in case of paddy cultivation. The economic value of women’s participation was accounting to be Rs. 2558 of the total cost of cultivation (Rs. 13567/- per ha) of sorghum. There was a glaring difference in wage rates revealing discrimination between men and women wage rates. The year to year (y-t-y) wage difference was only 12.73 during 2000-01 a decade ago, later grew to 35.13 during 2010-11. The lower wage rates to women were because female labour is available in plenty than male labour. Policy initiatives such as identify women as a key player in NRM both at micro and macro level, when the Govt. distributes surplus land, it has to consider the possibility of transferring the ownership of land to women encourage leasing out fallow land for cultivation of food crops through women SHGs, train the tribal women on how to make use of NFTP and other MFP without disturbing forest cover.
The Influence of Corporate Internal and External Factors on Bumn Share Prices: A Case Study in 12 BUMNs
Authors: Ahsan Mohammad
Published: November 2020

The Covid-19 pandemic has had a negative impact on the economy and other business sectors including the impact felt by BUMN. Research on the influence of internal and external factors of BUMN on BUMN stock prices was carried out using secondary data and observations on 12 BUMNs consisting of the steel and cement, construction, mining and food and health sectors. According to the data, the BUMN share price experienced a decline during the Covid-19 pandemic where the most affected were BUMN in the construction sector (-128%), mining (-74%), steel and cement          (-60%) and the food and health sector (-15%). This study explores internal and external factors in BUMN that have the potential to influence stock prices by analyzing the quantity using linear regression equations with the help of the SPSS statistical application. Several internal and external factors in SOEs that affect BUMN stock prices are current ratio (CR), return on assets (ROA), debt to equity ratio (DER), foreign exchange rates, inflation, economic growth and and the Covid-19 pandemic. The results show that there is an influence of internal and external factors of BUMN on BUMN stock prices and the most dominant factor affecting stock prices is the foreign exchange rate of 34.36%, economic growth of 32.11% and the Covid-19 pandemic of 1.84%. Meanwhile, the internal factors that have influence are ROA of 0.25% and DER of 0.15.

Authors: Simon Wekesa Waswa , Mutuku Winifred Nduku
Published: November 2020

Heat transfer fluids play a vital role in many engineering and industrial sectors such as power generation, chemical production, air-conditioning, transportation and microelectronics.

Aim: To numerically investigate the effect of double stratification on magneto-hydrodynamic boundary layer flow and heat transfer of an Eyring-Powell fluid.

Study Design: Eyring-Powell fluid is one of the non-Newtonian fluid that possess different characteristics thus different mathematical models have been formulated to describe such fluids by appropriate substitution into Navier-Stoke’s equations. The challenging complexity and the nature of the resultant equations are of great interest hence attract many investigations.

Place and Duration of Study: Department of Mathematics and Actuarial Science, Kenyatta University, Nairobi, Kenya between December 2019 and October 2020.

Methodology: The resultant nonlinear equations are transformed to linear differential equations by introducing appropriate similarity transformations. The resulting equations are solved numerically by simulating the predictor-corrector (P-C) method in matlab ode113. The results are graphically depicted and analysed to illustrate the effects of magnetic field, thermophoresis, thermal stratification, solutal stratification, material fluid parameters and Grashoff number on the fluid velocity, temperature, concentration, local Sherwood number and local Nusselt number.

Results: The results show that increasing the magnetic field strength, thermophoresis, thermal stratification and solutal stratification lead to a decrease in the fluid velocity, temperature, Sherwood number, Nusselt number and skin friction while an increase in the magnetic field strength, thermal stratification, solutal stratification, and thermophoresis increases the fluid concentration.

Conclusion: The parameters in this study can be varied to enhance heat ejection of Eyring-Powell fluid and applied in industries as a coolant or heat transfer fluid.
