Digitalization and the Social Lives of Older Adults: Protocol for a Microlongitudinal Study (Preprint)
Authors: Macdonald Birthe , Hülür Gizem
Published: May 2020

BACKGROUND

Digital technologies are increasingly pervading our daily lives. Although older adults started using digital technologies later than other age groups, they are increasingly adopting these technologies, especially with the goal of communicating with others. However, less is known about how online social activities are embedded in older adults’ daily lives, how they complement other (offline) social activities, and how they contribute to social connectedness and well-being.

OBJECTIVE

Data generated by this project will allow us to understand how older adults use digital communication in their daily lives to communicate with others, how this relates to well-being and social connectedness, and how communication using digital technologies differs from other types of communication depending on situational and individual characteristics.

METHODS

Microlongitudinal data were collected from 120 older adults from German-speaking regions of Switzerland to examine these questions. Data collection took place from April 2019 to October 2019. Data collection took place over different time scales, including event-based (reporting all social interactions for 21 days), daily (well-being, loneliness, and technology use every evening for 21 days), hourly (cortisol assessments 6 times per day for 3 days), and baseline (relevant interindividual characteristics, including sociodemographics, health, technology use, personality, and cognitive performance) assessments.

RESULTS

Data collection for this study was completed in November 2019. Participants reported an average of 96.35 interactions across the 21 days. Among the total 11,453 interactions, 5494 (47.97%) were face-to-face, and around 16% each were interactions by phone (1858, 16.16%), email (1858, 16.22%), and text message (1853, 16.18%). Otherwise, 246 (2.15%) of the interactions took place on social media, 96 (0.84)% were letters, and 54 (0.47%) of the interactions took place on videochat.

CONCLUSIONS

Participants used a variety of modalities in their daily communication, including digital means such as text messages, email, and video calls. Further analysis will provide more detail as to the role that communication via digital media plays in older adults’ daily lives.

Knowledge and Awareness-based Survey of COVID-19 in the Eye Care Profession, Facts Sealed Myths. (Preprint)
Authors: Sanyam Sandip Das , Sah Sanjay , Chaudhary Pankaj
Published: May 2020

BACKGROUND

Analysis of knowledge and awareness in the eye care profession is highly essential amid COVID-19 pandemic, myths have no place in medical research.

OBJECTIVE

To estimate the effect of myth in knowledge and awareness of eye care.

METHODS

A qualitative survey, designed by a focused group of researchers, to access the knowledge and awareness of COVID-19 in eye care practitioners. Questions were prepared and sent through an online link. Altogether, 25 questions (both open and closed-ended) were employed in the survey. The overall responses were coded with percentage calculation, and mythological facts were overruled if they persisted with appropriate justification.

RESULTS

Of the total delivered links, 51% (n=310) participated in the survey. Only 46% of the total participants were aware that COVID-19 is a disease and SARS-CoV-2 as the causative agent. The symptoms of COVID-19 were known to 94%, whereas only 54% were aware that everyone can get infected by SARS-CoV-2. Similarly, 49% of the participants had an idea about the mode of transmission of the disease and only 5% of the participants did not know the abbreviation of PPE. About 17% had no idea regarding RDT and 56% responded to RT-PCR as a confirmatory test for SARS-CoV-2. Almost 98% of participants recognized the WHO’s awareness message, but surprisingly 41% participants responded to another question felt that consumption of hot drinks kills the virus (is WHO’s awareness). Social distancing was key to restricting the disease spread; at the same time, about 41% had disagreement regarding PPE usage by eye care practitioners.

CONCLUSIONS

Eye care professionals seemed to be little behind the expected knowledge and awareness of COVID-19. One is recommended to follow the World Health Organization and National (Ministry of Health and Population, Nepal) guidelines for clinical practice and not to believe in baseless myths devoid of evidence.

Melampaui Subkultur/Post-Subkultur: Musisi sebagai Jalan Hidup Kaum Muda
Authors: Sutopo Oki Rahadianto , Wibawanto Gregorius Ragil , Lukisworo Agustinus Aryo
Published: May 2020

This study explores the struggle and its subjectivity among young people in Yogyakarta who choose being-musician as a way of life. Faced with limited job opportunity, they manage and keep alive their aspirations as mucisian in the local music scene. Their decisions to become musician embody a certain element of resistance against dominant view of work that encompasses the idea of a clear career projection. Even so, they do not always rely on the entrepreneurialism practice and do not neccesarily express class sentiment. Their diverse form of articulation is often constituted by construction of their subjectivity and lives trajectory. In this article, we use Hodkinson’s thought on ‘whole lives trajectories, Connel’s take on life in Global South and Beck’s theory on the redistribution of global risk to explore the subjectivity and plural voices of young musician in Yogyakarta. Based on the empirical data, we argue that throughout their lives trajectories, young musician intertwine with three social units that are unique to Global South context namely family, community, and wider social network either with subculture or post-subculture roots. In their lives trajectories—aside of those three social units—young musician are also faced with the redistribution of local and global risk.

A Catastrophe for Capitalism
Authors: Lane Jan-Erik
Published: May 2020

Given the utterly painful short-run chock of COVID-19 as well as the looming long-run threat of climate change, radical scholars suggest that the prevailing global economic system is flawed. Capitalism must be replaced by something else, but what? Klein discusses “Corona capitalism” and Chomsky dreams about an anarchistic economy. Piketty, Krugman and Stieglitz all call for major changes to American capitalism in particular. The fall in income will be dramatic for Western economies, but income constitutes the wealth of nations.

Published: May 2020

O artigo apresenta resultados de pesquisa desenvolvida no âmbito do PET/Educação do Campo/UFSC acerca da problemática com os recursos hídricos em municípios catarinenses e o trabalho de escolas com esta temática. Os municípios investigados são Urubici, Três Barras e Passos Maia, nos quais, respectivamente, são abordados o uso de agrotóxicos, a indústria do papel e as PCHs. Foram realizadas entrevistas com estudantes, docentes e moradores, e observações nos rios, fontes de água, lavouras e indústrias em questão. As conclusões apontam problemas de poluição, contaminação e apropriação privada dos cursos de água, sua íntima articulação com os setores prioritários da economia catarinense e com a forma de produção que visa o lucro e degrada o meio ambiente. Quanto ao trabalho escolar, identificamos que o tema água é abordado em todas as escolas, porém de forma descontextualizada dos problemas concretos, restrito à esfera do consumo e da responsabilização individual.
El Retorno al Humanismo en la Época de la Globalización
Authors: Cardoso Ruiz René Patricio
Published: May 2020

El presente trabajo, no pretende ser más que una pequeña reflexión en torno a las condiciones actuales de deshumanización creciente que vive la humanidad como resultado indirecto de lo que se ha dado en llamar globalización, después de la desaparición del campo socialista, el que actuaba como muro de contención frente a la voracidad del gran capital mundial; para que de alguna forma, desde las humanidades y las ciencias sociales combatan una idea impuesta a la fuerza, la de que no hay un mundo mejor posible, y de lo que se trata es solamente de mejorarlo. Pensar de esa forma nos conduciría a una pasividad anti reflexiva que permita la imposición universal de un parámetro maniqueo y destructivo.

Pensar, incluso, que después de la caída del “Muro de Berlín” no existe forma válida de socialismo humano, me parece un sin sentido. Lo que se destruyó, si es que realmente se destruyó, fue solamente un intento de construir un mundo mejor. Le apostamos a la construcción de un mundo mejor, y mientras más humano, mejor.
Fundamentos Estéticos de la Música Erudita Latinoamericana
Authors: Guerrero Mora José
Published: May 2020

El estado actual de la música erudita latinoamericana responde a intentos de originalidad estética que señale el genuino espíritu del ser latinoamericano en un universo cultural donde han primado los efectos de producciones musicales tocadas, desde tiempos remotos, por patrones dogmáticos de creación y expresión. Tras recorrer un largo sendero, desde el arribo de modelos culturales y artísticos foráneos, creados según las normas y estereotipos de tiempo y lugar, ha enfrentado conflictos y dilemas que han puesto en duda el legítimo anhelo de sentirse vocera de una manifestación musical con sentido universalista, esto es, con el derecho a figurar por su legitimidad en el escenario de las grandes producciones de un arte que, por naturaleza, es la expresión viva más intensa de la sensibilidad, con mayor razón, si esta sensibilidad identifica a un conglomerado humano que palpita en un continente donde la vida se agita en un maremágnum de contradicciones, pero a la vez, de posibilidades.

El Lenguaje Como Instrumento Técnico en José Gaos
Authors: Rivas Osorio Pedro Pablo
Published: May 2020

Lo que el texto pretende, es dejar en evidencia el acto en el que el lenguaje funge como articulador entre el sujeto, el acto o actividad de proferir el concepto y las relaciones que de este acto se derivan; en la lógica de José Gaos, la percepción y la comprensión. La ruta señalada para encontrar la percepción y la comprensión, se garantiza por el momento del “anticipo” en lo que el texto expone como una explicación o idea de sí mismo para que los participantes tengan una idea acerca de su asistencia o encuentro con el lenguaje que enuncia al sujeto, al concepto y las relaciones que de esto se derivan (Filosofía de la filosofía). El texto en definitiva, nos hace recordar una de las propiedades fundamentales del filosofar; todas las proposiciones que esta acción renuncia pueden y deben aplicarse al sujeto que la anuncia. El lenguaje en su versión “técnica” como “fenomenología de la expresión verbal” vuelve inteligible y coherente el devenir de la filosofía por la filosofía.
La Educación Musical en Latinoamérica: Reflexiones entre la Estética Decolonial y Altermoderna
Authors: Egas Villota Mario Fernando
Published: May 2020

Desde el original Sistema de Educación Musical surgido en Venezuela como proyecto social, son muchas las Redes que como eco de su exitoso desarrollo se implementan en varios países de América Latina. Ellas, sin embargo, enfrentan el reto de constituirse en una alternativa formativa para la potenciación de la sensibilidad humana desde la valoración de las características de los contextos sociales particulares como postura epistemológica que asume la ruptura no sólo de las precariedades económicas sino de la comprensión del arte musical como experiencia transformadora. De este modo surge la reapropiación de la aisthesis en tanto percepción sensible, en distanciamiento de una concepción clásica cercana a la estética de lo bello, que por otro lado implica la colonialidad manifiesta en la reproducción acrítica de principios educativos en el campo de la música, situados desde pilares como los repertorios, los instrumentos, las propuestas metodológicas de origen europeo, entre otros aspectos. Así mismo la pregunta sobre la formación como búsqueda o impulso de un devenir humano desde la emergencia de una nueva cultura altermoderna surgida en el mestizaje globalizado. Esta realidad convoca la reflexión de los programas de educación superior quienes afrontan el conflicto creciente por desintegrar los andamiajes de la tradición, enfocándose en la formación de un pensamiento creativo y una educación expresiva.
Racismo y Pensamiento Latinoamericano - La subalternización de la Diáspora africana en América
Authors: García Rincón Jorge Enrique
Published: May 2020

Este texto aborda la génesis de lo que Alberdi llamó la filosofía de lo americano (Biagini, 2005). Por lo tanto, examina si el tránsito, en términos epistémicos, de la sociedad colonial a la sociedad republicana significó una época de destete del pensamiento europeo o si, por el contrario, la misma se puede considerar como la continuidad de los patrones de poder y dominación colonial en el ámbito académico latinoamericano. Para la comprensión de las características de lo que se ha denominado pensamiento latinoamericano desde el siglo XIX hasta la primera mitad del siglo XX es de gran importancia encontrar el hilo conductor de las ideologías que lo antecedieron desde la constitución de América como escenario de colonización. Así mismo, vale la pena verificar si las categorías de eurocentrismo y darwinismo social están asociadas a los planteos de tipo racista de los primeros pensadores que hicieron gran parte de la historia intelectual en América. Por supuesto, me interesa analizar cómo este pensamiento se constituye en piloto para afianzar la subalternización de la Diáspora Afrolatina en el marco de los desarrollos de la academia latinoamericana. Finalmente, se esbozan alternativas al pensamiento clásico latinoamericano en el análisis de lo que se conoce hoy como pensamiento decolonial en el marco del proyecto de investigación Modernidad/colonialidad. En este escenario, en cuanto critica de la modernidad europea, es posible encontrar caminos para visibilizar el pensamiento propio de la Diaspora afrolatina.

El Desarrollo Local. Propuestas y Condiciones Necesarias
Authors: Raul Gutiérrez Ricardo
Published: May 2020

El desarrollo local ha estado adquiriendo importancia en el mundo, como opción a la extensión de la globalización que se inicia en la década del 70. Como la problemática de la globalización excede el ámbito económico, ocurre lo mismo con el desarrollo local. La apertura de las economías, el incremento de la productividad y la pérdida de las consiguientes protecciones, obligaron a reestructurar los sistemas productivos y las producciones. La propuesta de política de desarrollo local proyecta experiencias nacionales en países desarrollados, que consiguieron enfrentar, más o menos exitosamente, los problemas que debieron enfrentar cuando la competencia de otros países destruyó parte de sus estructuras productivas. La aplicación de políticas inspiradas en el desarrollo local se plantea como alternativa a desarrollar. En el discurso político se han popularizado varios de los instrumentos que estas políticas promueven, tales como la colaboración público-privada, las incubadoras, la transferencia de tecnología, la acción educativa y de investigación, la asociatividad entre actores, etc. La aplicación de estas medidas no ha sido todo lo exitoso que puede serlo, dadas las experiencias en la práctica de estas políticas en diversos países del mundo. Se analiza esta diferencia de resultados a partir de diferencias en las condiciones iniciales e inexistencia de situación de confiabilidad política, escasez de capital social y de cooperación, como asimismo errores de política pública.
Algunos Aspectos Teórico-Conceptuales y Situacionales que Soportan la Integración Can-Mercosur para la Economía Colombiana
Authors: Burgos Flórez Marco Antonio
Published: May 2020

El proceso de integración económica Can-Mercosur desarrolla empáticas formas de productividad en el desarrollo del sector agrícola de Colombia, a través del presente artículo se considerará de manera teórico-conceptual cuales han sido los movimientos benéficos y las desventajas de este proceso enmarcado en los niveles tales como: zona de libre comercio (ZLC), unión aduanera (UA), mercado común (MC), unión económica (UE) y por ultimo integración económica total (IET). Niveles imprescindibles en la formulación de los aspectos estáticos y dinámicos que determinan la actividad de consumidores como productores. Partiendo además de un análisis posible en una unificación que se visiona desde el Regionalismo y su carácter democrático siendo la “camisa de fuerza” para la economía nacional, a partir de ella se discurre cuáles son las causas endógenas y exógenas que generan grandes dificultades que justifican sus negaciones y sus efímeros logros para la Integración Regional, además de la necesidad de apelar a las metodologías “asimetrías” como formas de liderar que enmarcan la posibilidad de un progreso integral del territorio en elementos de ligaduras sociales, económicas, culturales, históricas, geográficas, que son la base del mercado regional para la economía colombiana.

Authors: Starov Aleksandr , Kalashnikov Sergei
Published: May 2020

The finite relationship between the forces and moments of plates and shells in the parametric form of the theory of small elastoplastic deformations is investigated of A.A. Ilyushin, to determine the load-bearing ca­pacity of structures from a material without hardening. A geometric image of the exact yield surface in the space of generalized stresses is obtained. In the first part of the article the conclusion of the final relation is given. In the second and third parts, by introducing other parameters, alternative equivalent dependences of the final rela­tionship have been developed and variants of its approximation for application in computational practice are considered. In the fourth part, additional properties of the final relationship are considered, the possibility and necessity of its use in problems of plastic deformation of plates and shells is shown.

Authors: Biryukov Alexander , Kravchenko Igor , Dobryshkin Evgeny , Biryukov Yuri , Kondrashchenko Valery
Published: May 2020

The subject of the study, considered in the article, is the technical condition of the housing stock of the Russian Federation, which is a totality of objects with a characteristic variety of structural and space-planning decisions and increased values of physical wear. The objective of the study conducted by the authors was to develop an optimization criterion for assessing the effectiveness of restoration of housing facilities based on determining the ratio of one-time costs for restoration work and current projected costs for operation and maintenance of an apartment house. Since an important stage in reproduction of the housing stock is preparation of design estimates for reasonable implementation of capital investments by property owners and government support measures for restoration of buildings, the topic discussed in this article is relevant. The scientific novelty of the study conducted by the authors is to develop a method for assessing the effectiveness of overhaul (reconstruction, modernization) of buildings, where the criterion is the choice of innovative design solutions and building materials when planning the restoration of housing facilities.
OPTIMIZATION PROBLEMS OF MATHEMATICAL MODELLING OF A BUILDING AS A UNIFIED HEAT AND POWER SYSTEM
Authors: Tabunshchikov Yuri , Brodach Marianna
Published: May 2020

The mathematical model of a building as a single heat energy system by the decomposition method is represented by three interconnected mathematical models: the first is a mathematical model of the energy interaction of a building’s shell with an outdoor climate; the second is a mathematical model of energy flows through the shell of a building; the third is a mathematical model of optimal control of energy consumption to ensure the required microclimate. Optimization problems for three mathematical models with objective functions are formulated. Methods for solving these problems are determined on the basis of the calculus of variations and the Pontryagin maximum principle. A method for assessing the skill of an architect and engineer in the design of a building as a single heat energy system is proposed.
USING THE CRITERION OF THE MINIMUM MATERIAL CAPACITY OF RODS UNDER STABILITY RESTRICTIONS FOR THE CASE OF MULTIPLE CRITICAL LOAD
Authors: Lyakhovich Leonid , Akimov Pavel , Malinowski Anatoly
Published: May 2020

As it is known, special criteria are formulated to evaluate the obtained solution of some optimization problems. In particular, we formulate a criterion that allows us to estimate the proximity of the decision on the rod of the lowest weight and the restrictions on the resistance to the minimum material-intensive for rectilinear rods for certain types of cross sections. The criterion is based on the analysis of stresses from bending moments arising from the loss of stability. If the least critical force is not a multiple, then the form of loss of stability and the corresponding diagram of moments are the only ones. At multiplicity of the least critical load there are mul­tiple forms of loss of stability, and any of their linear combination is also its own form. To estimate the obtained solution, it is necessary to form a combination of multiple forms of buckling and the corresponding diagram of bending moments, which will serve as the basis for the use of the criterion. This paper proposes an approach that allows to determine such a combination of multiple forms, which will be the basis for the application of the crite­rion of proximity of the obtained solution to the minimum material-intensive.
A PROBABLISTIC APPROACH TO EVALUATION OF THE ULTIMATE LOAD ON FLEXURAL RC ELEMENT ON CRACK LENGTH
Authors: Solovyev Sergey
Published: May 2020

The fracture mechanics of concrete and reinforced concrete is a promising direction in the development of methods for reinforced concrete structural elements design and inspection. At the same time, probabilistic methods of design and behavior analysis of structural elements are of particular interest. The article describes a probabilistic approach to load-bearing capacity and reliability analysis of flexural reinforced concrete elements based on the crack length criterion. The functional relationship between the critical stress intensity coefficient of concrete and the design compressive strength of concrete is given. The article presents a method for the reliability analysis of flexural reinforced concrete elements at the operational stage with limited statistical data about the critical stress intensity coefficient of concrete. The ultimate value of the failure probability (or reliability index) should be set for each object individually based on the value of the acceptable risk.

Published: May 2020

Necrotizing Fasciitis is a rapidly progressing soft tissue infection primarily involving the superficial fascia and subcutaneous tissue.In this case series, we reviewed the clinical presentation of the Necrotising fasciitis cases, the critical role of early diagnosis, to assess the important predictor of mortality and importance of LRINEC scores in proven cases. The data was collected prospectively and retrospectively for 16 consecutive patients who were admitted at our institution with Necrotising Fascitis between January 2010 and April 2018. Patients were subdivided in to two sub groups, survived (n= 12) and deceased (n=4).The both groups were assessed in terms of age, gender, predisposing factors and the difference between the LRINEC score.Age ranged from 30 to 77 years (average age 54.6). The most common associated comorbidity was DM in 6, followed by IVDU in 3 patients.We noted mean LRINEC score 9.5 in those patients who survived and 9.75 with mortality group.Group statistics revealed the age is an important factor for predicting high mortality and diabetes mellitus being the most common comorbid condition. We noted that streptococci and staphylococci remain the virulent and commonest organism.We noted that LRINEC score is an important to predict the morbidity and mortality as the mean score was 9.5 (range 6-12), but no significant difference in the LRINEC score noted in the deceased vs survived group. We strongly recommend the high clinical suspicion, prompt investigations and resuscitation with appropriate antimicrobial therapy followed by expedited surgical debridement to reduce the morbidity and mortality.
Predicción de actitud hacia personas con VIH/SIDA y hacerse prueba del VIH
Authors: Moral de la Rubia José , Valle de la O Adrián
Published: May 2020

Esta investigación tiene como objetivo contrastar un modelo para predecir actitud hacia personas que viven con VIH/SIDA (PVVS) y hacerse la prueba del VIH. Se aplicó la Escala de Actitud hacia PVVS, la escala de actitud hacia hombres homosexuales y lesbianas, la escala de autoritarismo de ala derecha y preguntas sobre datos sociodemográficos, clínicos, de conducta sexual y relaciones de amistad a 202 estudiantes de medicina mexicanos. Se usó un muestreo no probabilístico. Con buen ajuste a los datos, una actitud de mayor rechazo hacia PVVS fue predicha por orientación heterosexual, ser hombre y autoritarismo. La actitud hacia personas homosexuales tuvo una correlación sustantiva con actitud hacia PVVS, pero no fue un predictor. Hacerse la prueba del VIH fue predicho por ser hombre, actitud de aceptación hacia PVVS, tener amigos homosexuales y autoritarismo. Se concluye que el modelo especificado de corte psicosocial presenta gran capacidad explicativa.
İki Farklı Örneklem Tekniği Kullanılarak Oluşturulan Heyelan Duyarlılık Haritalarının Frekans Oranı (FO) Yöntemi ile Karşılaştırılması
Authors: Dağdelenler Gülseren
Published: May 2020

Heyelanların verdiği zararların azaltılması amacıyla heyelan oluşumunun önceden tahmini ve heyelana duyarlı
alanların literatürde mevcut yöntemlerle belirlenmesi son derece önemlidir. Bu doğrultuda, heyelanların aynı
litolojide geliştiği Bartın ilinin Ulus ilçesinin heyelan duyarlılık haritalamasının yapılması amaçlanmıştır. Çalışmanın
önemli noktası, Chebyshev teoreminin bu çalışmada seçilen çalışma alanı için sınanması ve bu yöntemle üretilen
duyarlılık haritasının mevcut literatürde sıklıkla kullanılan tüm heyelan kütlesi içerisindeki piksel sayma tekniği ile
oluşturulan veri seti kullanılarak üretilen heyelan duyarlılık haritası ile karşılaştırılmasıdır. Çalışma alanında toplam
195 adet heyelan haritalanmış ve heyelanlı ve heyelanlı olmayan alanların belirlenmesinde Chebyshev teoremi
ve tüm heyelan kütlesi içerisindeki piksel sayma tekniği olmak üzere iki farklı örneklem tekniği kullanılmıştır.
Heyelan duyarlılık analizlerinde kullanılmak üzere topoğrafik yükselik, eğim, bakı, eğrisellik ve NDVI (normalize
edilmiş fark bitki örtüsü indeksi) olmak üzere toplam 5 adet parametre haritası üretilmiştir. Her iki örneklem tekniği
kullanılarak yapılan duyarlılık analizlerinde literatürde sıklıkla kullanılan Frekans Oranı (FO) yöntemi kullanılmış
ve iki farklı harita üretilmiştir. Duyarlılık haritalarının performansı ise Eğri Altında Kalan Alan yöntemine (ROCEAA)
göre değerlendirilmiş ve EAA değerleri sırasıyla Chebyshev teoremi için 0.78 ve tüm heyelan kütlesindeki
piksel sayılarına göre yapılan örneklem tekniği için ise 0.72 olarak belirlenmiştir. Bu değerlere göre, üretilen her
iki duyarlılık haritasının da kabul edilebilir düzeyde olduğu ve Chebyshev teoremi ile örneklem yapılarak üretilen
duyarlılık haritasının performansının, diğer örneklem yöntemine göre nispeten daha yüksek çıktığı görülmüştür.
Elde edilen bu sonuç, çalışmada kullanılan Chebyshev yönteminin de heyelan duyarlılık haritalama çalışmalarında
etkin olarak kullanılabilir alternatif bir yöntem olduğunu ve bu yöntemle üretilen duyarlılık haritasının da başarılı bir
kestirime sahip olduğunu göstermiştir.
Menderes Masifi′nde Açılmış Açık Ocak Albit Madenindeki Bir Duraysızlığın Nedenlerinin Araştırılması ve Robotic Total Station Cihazı Kullanılarak Yenilme Öncesinde Şev Hareketlerinin İzlenmesi
Authors: Karagöz Saffet Deniz , Kıncal Cem , Koca Mehmet Yalçın
Published: May 2020

19.12.2018 tarihinde Menderes Masifi içinde, ayrışmış gnayslarda yer alan bir açık ocak madeninde büyük
ölçekli bir heyelan meydana gelmiştir. Hemen hemen şev yüzeyine paralel uzanan bir yenilme yüzeyi oldukça sığ
bir derinlikte gelişmiştir (Maksimum derinlik: 17 m). Duraysızlığın geliştiği şevin genel açısı 25° ve genel şev
yüksekliği ise 80 m′dir (Kotlar: 490 m – 410 m). Kayan malzeme miktarı ise yaklaşık 700×103 m3′tür. Açık ocaktaki
kaya şevlerinde duraysızlık tümüyle gerçekleşmeden önce kayda değer deformasyonlar meydana gelmiştir. Heyelan
oluşumu öncesindeki söz konusu şev hareketlerinin zamana bağlı olarak (2017–2018 yılları arası, 750 gün) izlenmesi
ve duraysızlığın nedenlerinin araştırılması bu çalışmada amaçlanmıştır. Hareket izleme çalışmaları sırasında günlük
ve saatlik yağış miktarları da ölçülmüş ve kaydedilmiştir. Jeolojik yapı ile duraysızlığın mekanizması arasındaki
ilişkiyi belirlemek için şev hareketi ölçüm verileri eş zamanlı yağış verileriyle birlikte “GeoMoS” bilgisayar
programı kullanılarak değerlendirilmiştir. Önceden cevherin tavan bloğunda küçük ölçekli bazı şev duraysızlıkları
not edilmiştir. Diğer taraftan, gelişmiş yenilme yüzeyi boyunca, yeraltı suyu basınç değişimlerinin tetiklediği
daha büyük yer değiştirmeleri kapsayan yoğun yağışlı dönemler, cevherin tavan bloğunda meydana gelen büyük
ölçekli yenilmeyi ilerletmiştir. Kurak dönemlerde, şev hareketlerinin hızı ortalama 3.5 mm/gün′dür. 04.12.2018
tarihinde gerçekleştirilen üçüncü dekapaj çalışması nedeniyle açık ocakta şev hareketleri bir miktar ivmelenmiştir.
Şev topuğunda gerçekleştirilen kontrolsüz kazıya kadar (14.12.2018), şevin toplam bileşke yer değiştirme miktarı
100 cm artmıştır ve bu dönemde hareketlerin ortalama hızı 10 cm/gün olarak hesaplanmıştır. Son olarak, topuk

Designing remote education in a VUCA world
Authors: Pultoo Anand , OOJORAH Avinash
Published: May 2020

The goal of this article is to identify and share the best practices and innovations to enable teaching and learning to take place during times of VUCA (Volatile, Uncertain, Complex, and Ambiguous) such as the coronavirus pandemic. This will help lay the foundations for more inclusive and equitable approaches to education when the crisis subsides. The main response to school closures is to dive headlong into academic cyberspace and remote learning, creating a human-machine symbiosis. Ideally, specific contents, learning outcomes, and a set of instructions are desirable. Different media and technologies can be used to assist students to learn in different ways and achieve different outcomes, thus also individualizing learning more. Technologies can be compared along several characteristics. These characteristics form a basis for analyzing new technologies, to see where they fit within the existing environment, and to evaluate their potential benefits and limitations. Nowadays, technologies have a tendency to become more ‘communicative’ and ‘media rich’, thus offering educators and students powerful tools to attain desired learning outcomes.

Common food additives endorsed by Food and drug Organization "FDA" are utilized to preserve taste. The display think about examined the perilous impacts of sodium nitrite, sodium benzoate and their blend which utilized in fabricating of the food additives on a few biochemical parameters and  histo-pathological examination in male rats. Male rats were divided into four groups; group I utilized as control, group II and III were treated orally with sodium nitrite NaNO2 (80 mg/kg BW) and sodium benzoate (SB) (200 mg/kg BW), separately. Group IV was treated orally with the blend of sodium nitrite and sodium benzoate. Rats were managed their dosages each day for 8 weeks. It appeared that sodium nitrite, sodium benzoate and their blend (NaNO2 and SB) initiated a critical increment within the serum levels of aspartate aminotransferase "AST", alanine aminotransferase "ALT". Antioxidant proteins (GSH, CAT) within the liver tissue recorded a decrease while, MDA recorded an increase action level within the tested groups. Over expression in p53 happened in exploratory groups which were treated by NaNO2, SB and their blend. The present study concluded that the blend of food additives can actuate harmfulness within the liver of rats. In conclusion, it is noted that food additives induced hepatotoxicity within the liver. It diminished the antioxidant chemicals (GSH, CAT) and elevated the activity level of the MDA and increment tumor silencer quality p53 in liver tissue. Food additive substances caused changes in biochemical parameters (ALT, AST). The utilization of food additives must be diminished. The usage of the mixture of sodium nitrite and sodium benzoate induced changes in biochemical parameters and immune-histopathology.

QM/MM Molecular Dynamics Investigation of the Binding of Organic Phosphates to the 100 Diaspore Surface

Published: May 2020

The fate of phosphorus (P) in the eco-system is strongly affected by the interaction of phos- phates with soil components and especially reactive soil mineral surfaces. As a consequence, P immobilization could occur which eventually leads to P inefficiency and thus unavailability to plants with strong implications on the global food system. A molecular level understanding of the mechanisms of the P binding to soil mineral surfaces could be a key for the development of novel strategies for more efficient P application. Much experimental work has been done to understand P binding to several reactive and abundant minerals especially goethite (α-FeOOH). On the other hand, atomistic modeling of the P-mineral molecular systems using molecular dynamics (MD) simulations is emerging as a new tool which provides more detailed information regarding the mechanisms, nature, and strength of these binding processes. The present study characterize the binding of the most abundant organic phosphates in forest soils, inositol hexaphosphate (IHP) and glycerolphosphate (GP), to the 100 diaspore (α-AlOOH) surface plane. Here, different molecular models have been introduced to simulate typical situations for the P-binding at the diaspore/water interface. For all models, quantum mechanics/molecular mechanics (QM/MM) based MD simulations have been performed to explore the diaspore–IHP/GP–water interactions. The results provide evidence for the formation of monodentate (M) and bidentate (B) motifs for GP and M and as well as two monodentate (2M) motifs for IHP with the surface. The calculated interaction energies suggest that GP and IHP prefer to form the B and 2M motif, respectively. Moreover, IHP exhibited stronger binding than GP with diaspore and water. Further, the role of water in controlling binding strengths via promoting of specific binding motifs, formation of H-bonds, adsorption and dissociation at the surface, as well as proton transfer processes is demonstrated. Finally, the P-binding at the 100 diaspore surface plane is weaker than that at the 010 plane highlighting the influential role of the coordination number of Al atoms at the top surface of diaspore.
AIE Stereoisomers with Huge Differences in Luminescence Behavior and Biomedical Activity

Published: May 2020

Stereoisomers that differ only in spatial orientation of their atoms could exhibit distinctive properties and have attracted immense interest in drug development and material science. Herein, a series of AIE-featured stereoisomers with pronounced difference in luminescent and biomedical activities were efficiently synthesized and easily purified. One of the isomers in the E/Z pair is emissive with high fluorescence quantum yield at room temperature, while the other one is nearly non-emissive. As the isomers could transform between each other under UV irradiation, the light-up cell imaging was successfully demonstrated using the non-emissive isomer as a turn-on probe via isomerization process. Analysis of crystal packing patterns illustrated that the contrasts in void space possibly caused the difference in molecular motion and thus led to their distinct luminescence properties. Further, the E/Z isomers displayed remarkable difference in enzymatic conversion rates and cellular toxicities for several cancer cell lines. The distinctive luminescence properties of the isomeric pair provided a powerful tool to image those divergencies in biomedical activity, holding great potential for visualizable drug screening and development.
