THE ROLE OF SOCIAL CONNECTEDNESS IN THE CORONAVIRUS DISEASE (COVID-19) PANDEMIC OUTCOME
Authors: Stojkoski Viktor , Tevdovski Dragan
Published: January 2021

The magnitude of the coronavirus disease (COVID-19) pandemic has an enormous impact on the social life and the economic activities in almost every country in the world. Besides the biological and epidemiological factors, a multitude of social and economic criteria also govern the extent of the coronavirus disease spread in the population. Consequently, there is an active debate regarding the critical socio-economic factors that contribute to the resulting pandemic. In this paper, we contribute towards the resolution of the debate by examining the role of an individual!s social connectedness in the extent to which the coronavirus spread. To measure social connectedness we create a network in which nodes represent countries and the interactions between pairs of countries are given by the number of shared Facebook contacts, whereas the coronavirus outcome is simply quantified as the number of registered cases per million population in the country. We find that there exists a robust and stable relationship between the level social importance of a country as well as the degree to which its people mix, and the outcome of the coronavirus health crisis. Countries which take a more central role in the network of social connections are also more susceptible to the coronavirus, whereas countries where there is less social mixing are less affected by the induced disease. Our results are an empirical verification for standard theories, which suggest that social network structures play a critical role in disease spreading processes. More importantly, they serve as a validation that social distancing measures introduced by governments are essential policies for preventing a fatal coronaviru

Authors: Bedjeti Baftijari Artina , Nakov Leonid
Published: January 2021

Most of the economic activities are becoming highly digital. In the past several years changes in the technological improvements and financial innovations had an enormous impact on the modern financial system. Worldwide, the banking industry has changed and integrated the financial technology (FinTech) in its everyday routine. Nowadays, for some financial members FinTech provides a big threat and a challenge for the traditional banking, while for some others it provides an opportunity for more flexibility, better service functionality and higher service quality. Overall, banks adopt innovations to satisfy customers’ demands, despite the risks and challenges imposed from FinTech and new financial product development (NFPD). In general banks benefit from opportunities of the new product development in the aspect of allocating more efficiently the resources, reduction in transaction costs, promotion, revenue growth and profitability. The aim and objective of this paper is to identify and evaluate the main risks related to development of FinTech and financial innovations that banks are exposed to (on micro and macro level), and to provide recommendations on the reduction of those risks and controlling them. Based on literature review, researches proved that one of the major obstacle to firm`s innovativeness is the negative impact of the new financial product development on banking risks. It is recommended that in times of technological boom commercial banks should invest their available funds in suitable techniques for successfully accepting new financial product development.

Published: January 2021

This study assesses the performances of forest personnel in Akwa Ibom State in meeting their target revenue for the state using qualitative and quantitative approaches. The primary data were obtained using a structured questionnaire, oral interviews, and direct observation, while the secondary data were obtained from all the 31 Divisions and the Directorate of Forestry in Akwa Ibom State. Data collected were analyzed using the descriptive and stochastic frontier analysis to assess efficiency The results obtained showed that the majority of the respondents were male (59.50%), in their economically active and productive age bracket (50.41), attended tertiary education (79.33%), were married (69.42%), had a family size of fewer than 5 members (71.90%), and received a monthly income of ₦41,000 - ₦50,000 (42.15%). Also, the majority of the respondents had been in service for 11 – 15 years (30.23%), resided in their stations (72.09%), and received various forms of in-training (65.12%) to enhance their effectiveness or performance. Most of the Uniformed Field staff patrolled their divisions daily with their superior visiting their divisions more than once a month. The majority (53.84%) of the Forest Officers had less than 10 years' experience and their technical efficiency ranged from 0.35 to 0.97. The study, therefore, recommends that a more conducive working environment should be provided for the forest personnel to be able to optimize their performances which would translate to increased revenue generation for the state.

Effect of Shear Wall Location On Seismic Performance of High Raised Buildings
Authors: Kumar Gajagantarao Sai , Rao Purushotham , Ganesan Partheepan
Published: January 2021

Multi-storey buildings tend to get damaged mainly during earthquake. Seismic analysis is a tool for the estimation of structural response in the process of designing earthquake resistant structures and/or retrofitting vulnerable existing structures. The principle purpose of this work is to analyze and design a building with a shear wall and also to find the appropriate position of shear wall that result in maximum resistance towards lateral forces and minimum displacement of the structure. In this study, a G+7 multi-storey building of 15 m ×20 m in plan area has been chosen and modelled using ETABS. The developed model was validated by solving manually and the results were validated in ETABS. Thereafter, 4 different new plans were modelled in ETABS located in the same earthquake zone area. These plans have shear wall concepts are implemented on the building at four different locations. Seismic, vibration and response spectrum analysis were performed on these structures. Salient parameters such as storey stiffness, storey displacement and storey drift were computed using the ETABS model. These were compared with that of the frame having no shear walls. By comparing the results obtained at different shear wall locations, the best plan with the shear wall having minimum lateral storey displacement and maximum stiffness is suggested for this location.
Interactive Learning: The Sounds of Bonne Chance
Authors: Fowler Wesley , Gray Alex
Published: January 2021

Our Project, Bonne Chance, meaning good luck in French, is an immersive language learning game that manifests in the form of a mobile app. The game is designed as a course-companion for French 111 and 112 beginning language courses for college students. Instead of merely computerizing old teaching practices or creating grammar practice cards, we are radically re-envisioning the design of the learning experience. This project endeavors to build an “ecology of learning that extends beyond the four walls of an institution and engages [students] in ways that are exciting, empowering and culturally relevant” (Salen et al., 201100. The Project functions under four teams: the coding team, the user experience engagement team, the music curation and production team, and the app development team. As the music team, we focus on the music and sounds of Bonne Chance. The music and sounds of Bonne Chance contribute to this ecology by curating an authentically French soundtrack of pre-composed and original music, stimulating the learning environment, creating a sense of historical accuracy, and channeling the primary purpose of the game, which is to help immerse students in the French language. By conducting research into French composers and cultural trends throughout the ages, French musical history can be characterized as a diverse and central figure in the arts of humanity. French history has shaped human history, and its music sheds light on the roots of its global influence. The game itself is currently still in a series of prototype phases as we continue to test our most viable product [MVP]. Through our game-based learning application, our audience of elementary-level French students will gain language learning skills and intercultural empathy. Working in an innovative studio environment has allowed us to grow in the domains of collaboration, project management, programming, music history, research, music composition, music arranging, and music production. ­

IMPLEMENTATION OF RSA KEY GENERATION BASED ON RNS USING VERILOG
Authors: M VISHAK , SHANKARAIAH N.
Published: January 2021

RSA key generation is of great concern for implementation of RSA cryptosystem on embedded system due to its long processing latency. In this paper, a novel architecture is presented to provide high processing speed to RSA key generation for embedded platform with limited processing capacity. In order to exploit more data level parallelism, Residue Number System (RNS) is introduced to accelerate RSA key pair generation, in which these independent elements can be processed simultaneously. A cipher processor based on Transport Triggered Architecture (TTA) is proposed to realize the parallelism at the architecture level. In the meantime, division is avoided in the proposed architecture, which reduces the expense of hardware implementation remarkably. The proposed design is implemented by Verilog HDL and verified in matlab. A rate of 3 pairs per second can be achieved for 1024-bit RSA key generation at the frequency of 100 MHz.
A NEW APPROACH FOR INSTIGATING SECURITY USING SINGLE ZOOM MOUSE CLICK GRAPHICAL PASSWORD
Authors: SEBASTIAN MERIN , NARAYAMPARAMBIL BIJU ABRAHAM
Published: January 2021

Due to growing hazards to networked computer system, there is great need for security innovations. Authentication is the process of security to information. User authentication is one of the significant topics in information security. Commonly used authentication is alphanumeric passwords, biometrics and smart card. At present day upcoming popular method is graphical password. In graphical password systems authentication is based on clicking on image rather than typing alphanumeric strings .The motivation to develop graphical password is the fact that human can remember picture better than text. In this we propose a graphical password scheme which is more secured than other method. This method also depends not only on image but also number of mouse click on the image. This method reduces the huge image database, as well as images being too simple to cause collisions on points selected for different users.

EFFICIENT LOAD BALANCING IN PEER-TO-PEER SYSTEMS USING VIRTUAL SERVERS
Authors: JACOB SUBY MARIA
Published: January 2021

Load balancing is a critical issue for the efficient operation of peer-to- peer networks. With the notion of virtual servers, peers participating in a heterogeneous, structured peer-to-peer (P2P) network may host different numbers of virtual servers, and by migrating virtual servers, peers can balance their loads proportional to their capacities. Peers participating in a Distributed Hash Table (DHT) are often heterogeneous. The existing and decentralized load balance algorithms designed for the heterogeneous, structured P2P networks either explicitly construct auxiliary networks to manipulate global information or implicitly demand the P2P substrates organized in a hierarchical fashion. Without relying on any auxiliary networks and independent of the geometry of the P2P substrates, this paper present ,a novel efficient, proximity-aware load balancing algorithm by using the concept of common virtual servers, that is unique in that each participating peer is based on the partial knowledge of the system to estimate the probability distributions of the capacities of peers and the loads of virtual servers. The movement cost can be reduced by using common virtual server
A BIO GENETIC PROCESS TO REPLICAS-FREE REPOSITORY
Authors: VENKATESWARLU N. , SIREESHA D.
Published: January 2021

Several systems that rely on consistent data to offer high-quality services, such as digital libraries and ecommerce brokers, may be affected by the existence of duplicates, quasi replicas, or near-duplicate entries in their repositories. Because of that, there have been significant investments from private and government organizations for developing methods for removing replicas from its data repositories. This is due to the fact that clean and replica-free repositories not only allow the retrieval of higher quality information but also lead to more concise data and to potential savings in computational time and resources to process this data. In this paper, we propose a genetic programming approach to record deduplication that combines several different pieces of evidence extracted from the data content to find a deduplication function that is able to identify whether two entries in a repository are replicas or not. As shown by our experiments, our approach outperforms an existing state-of-the-art method found in the literature. Moreover, the suggested functions are computationally less demanding since they use fewer evidence. In addition, our genetic programming approach is capable of automatically adapting these functions to a given fixed replica identification boundary, freeing the user from the burden of having to choose and tune this parameter.

Power and area efficient multiplier using CMOS logic circuits for applications in various digital signal processors is designed. This multiplier is implemented using Vedic multiplication algorithms mainly the "Urdhvatiryakbhyam sutra" , which is the most generalized one Vedic multiplication algorithm [1] . A multiplier is a very important element in almost all the processors and contributes substantially to the total power consumption of the system. The novel point is the efficient use of Vedic algorithm (sutras) that reduces the number of computational steps considerably compared with any conventional method . The schematic for this multiplier is designed using TANNER TOOL. The design is then verified in T-SPICE using 0.18 um CMOS technology library file. The analysis is made for various voltages across a range of 2.5V to 5V, to validate the design. A CMOS digital multiplier, with low power consumption and high linearity is proposed. The results prove that the proposed multiplier consumes 80% less power compared to the gate level analysis done earlier. The core area of the proposed multiplier is 737 um2 . Paper presents a systematic design methodology for this improved performance digital multiplier based on Vedic mathematics.
NOVEL DIGITAL LOCK SYSTEM

Published: January 2021

In this paper we have proposed a new digital lock model which is primarily designed for low cost intermediate security purpose. Even though there are digital locks available this one is designed keeping the common man in mind. It will be the first digital locking system that would be available at a price less than 700 rupees. The recent increase in burglary levels proves the fact that the lever locking system is no more reliable and effective, but on the other hand the present digital locks are around 3000 rupees making it over priced. So this clearly shows the need for an intermediate effective digital locking system. Our novel digital locking system is aimed exactly to solve the above stated problem. Our model is an outcome of embedded system and can works using an 8051 microcontroller interfaced with a 16*2 lcd to perform logical operations. The input is given by the user using 3*3 matrixes key padded system. The locking system consist of a power lock which is widely used in automobiles, it primarily consist of an dc motor which on rotating moves the lever back and forth depending on the direction of rotation. The interrupt pins are used to clear the buzzer which is connected to port 3 pins which thereby notifies the user immediately in case of theft or burglary.

As relações de gênero e a cultura brasileira no ambiente de trabalho: estudo com mulheres de aplicativos de mobilidade urbana
Authors: Colodetti Ana Paula , Melo Marlene
Published: January 2021

Este estudo teve por objetivo analisar como as relações de gênero e as particularidades da cultura brasileira são percebidas por mulheres motoristas de aplicativos de mobilidade urbana em sua atuação profissional e no ambiente de trabalho. A metodologia adotada para o desenvolvimento desta pesquisa foi uma abordagem qualitativa-descritiva, tendo sido entrevistadas 11 mulheres atuantes como motoristas de aplicativos de transporte na região metropolitana de Belo Horizonte. Os dados obtidos a partir das entrevistas com roteiro semiestruturado foram analisados considerando a concepção de gênero de Scott (1995), os pressupostos teóricos de dominação masculina e de violência simbólica de Bourdieu (2012) e a percepção da mulher como sujeito de transformação do campo social e cultural de Touraine (2007). Ao final do estudo, constatou-se um movimento incipiente de aceitação social e cultural percebido pelas entrevistadas em sua atuação como motoristas de aplicativos de mobilidade urbana, impulsionado principalmente por um cenário de crise econômica e de desemprego, mas também como consequência do empoderamento da mulher que, não se reconhecendo vítima de uma estrutura patriarcal opressora, persistente e dominante, se percebe sujeito transformador de sua própria realidade.
Linguagem, escolaridade, relações profissionais: metroviárias de Belo Horizonte e Contagem/MG
Authors: Faria Antônio , Gazolla Dimas , Barros Vanessa
Published: January 2021

Este estudo procura contribuir para a compreensão de uma mudança recente no Brasil, e mais especificamente na região metropolitana da capital de Minas Gerais: o surgimento de mulheres como trabalhadoras em ferrovias e sobretudo em metrôs, alterando um paradigma profissional que foi masculino durante décadas. Um dos aspectos que impulsionam essa mudança de paradigma é o avanço tecnológico que, enquanto diminui a necessidade de esforço físico no trabalho, aumenta a necessidade de esforço cognitivo intelectual e, em consequência, de escolaridade proficiente. Essa mudança de paradigma desenvolve-se em meio a conflitos que envolvem as relações profissionais das metroviárias com seus colegas de trabalho, por um lado, e com os usuários do metrô, por outro lado. O presente estudo, assim, procura contribuir para o conhecimento de uma mudança que atinge um amplo conjunto de trabalhadores e trabalhadoras.
Relações de gênero e divisão sexual do trabalho: atuação das mulheres matemáticas na carreira acadêmica
Authors: Gaudêncio Eliane
Published: January 2021

O artigo traz discussões e propõe uma análise crítica sobre as relações de gênero presentes e divisão do trabalho presentes na carreira matemática, ilustrando assim uma realidade de desigualdade, na qual questões históricas embasadas pelo patriarcado, sociais, culturais, familiares e de estereótipos de gênero, com seus discursos organizacionais tendenciosos no que se refere ao gênero, influenciam nas escolhas acadêmicas e profissionais das mulheres, consequentemente, esse forte viés sexista, que permeia a ciência, resultou ser a matemática como uma área de estudos que têm um menor número de mulheres inseridas e, também é vista tradicionalmente como uma atividade para homens, além disso, outros componentes problemáticos à igualdade de gêneros são os chamados teto de vidro e labirinto de cristal, sem perder de vista os vários mitos, que foram se moldando ao longo dos anos acerca da relação mulher versus matemática. São, portanto inúmeros os indícios de mecanismos sutis geradores de barreiras para as mulheres, logo dificultando a sua progressão acadêmica e, não por acaso, é um dos temas de discussão e denúncia sobre exclusão do feminino no contexto científico, nas pautas feministas. Trata-se de uma revisão bibliográfica e documental de estudos realizados sobre a temática. Espera-se contribuir para um melhor entendimento acerca das modulações da inserção feminina no campo de estudo e ensino da matemática.
A presença da mulher na Gastronomia: de dona de casa à cozinheira profissional
Authors: Dias Frederico , Silva Letícia , Teixeira Natália
Published: January 2021

É sabido que a sociedade sempre impôs para a mulher que ela tinha a obrigação de ser subordinada ao homem e que seus afazeres deveriam ser exclusivamente designados a tarefas do lar. Devido a isso, a mulher ainda enfrenta diversas dificuldades para ingressar-se no mercado de trabalho, inclusive o gastronômico, uma vez que as pessoas ainda não aceitam que as mulheres possam ocupar um cargo que sempre foi dominado pelo gênero masculino. Deste modo, foi constatado por meio de entrevistas realizadas com homens e mulheres, que o machismo estrutural e o preconceito contra as mulheres ainda é o que mais as prejudica no momento de se inserirem em uma cozinha profissional.
O lugar da mulher como trabalhadora no Japão
Authors: Costa Paloma , Moreira Lucimara , Guimarães Ludmila
Published: January 2021

A proposta deste artigo é compreender o lugar da mulher como trabalhadora no Japão. Para tanto, realizou-se uma pesquisa bibliográfica a fim de apresentar a dinâmica e a evolução do mercado de trabalho marcado pelo fim do governo feudal. As guerras e influências econômicas externas foram cruciais para a construção de uma sociedade japonesa, baseada em um sistema econômico paternalista e familialista . Nesse sentido, esse sistema acaba por privilegiar a carreira masculina e relegar à mulher uma posição social reduzida à maternidade. Por fim, a construção de um discurso do lugar da mulher no mercado de trabalho japonês à responsabiliza por não se dedicar integralmente ao emprego, e tem servido para reforçar as barreiras de ascensão e permanência de mulheres em suas carreiras.

In mammalian cells, proliferation is controlled by the cell
cycle, where cyclin-dependent kinases regulate critical
checkpoints. CDK4 is considered a highly validated anticancer
drug target due to its essential role in regulating cell cycle
progression at the G1 restriction point. Our objective is
to design novel CDK4 inhibitors using Structure-Based Drug
Design and Quantitative Structure-Activity Relationship
techniques. We used bioinformatics tools and biological
databases. QSAR study of CDK4 inhibitors has given us an
idea of the physicochemical features of studied compounds
and their correlation with the IC50 activity. The docking study
has helped to highlight the molecule key elements to refine
in order to get a more potent compound of CDK4.The
Molecule under the code 21366124 which has the low IC50=

Mobilização do trabalho e escolarização no processo de modernização em comunidades rurais no Vale do Jequitinhonha (Minas Gerais, Brasil)
Authors: Leite Ana Carolina Gonçalves
Published: January 2021

Com este artigo, buscamos discutir a relação entre mobilidade do trabalho e escolarização a partir de uma análise do processo de modernização em comunidades rurais do Vale do Jequitinhonha (Minas Gerais, Brasil) e de levantamentos realizados entre os anos de 2004 e 2014, para estudos e reflexões conduzidos no período (LEITE, 2010, 2015). No que diz respeito ao momento contemporâneo, notaremos o amplo processo de escolarização experimentado pelos jovens do campo e como isso implica processos migratórios, ainda que temporários ou pendulares, mudando a relação entre reprodução familiar e emprego na terra. A partir de uma leitura histórica e com uma extrapolação da discussão sobre a migração para o problema conceitual da mobilidade do trabalho, ademais, encontraremos a escolarização como momento de um processo de autonomização não apenas entre terra e trabalho, como no caso daqueles filhos de camponeses que se escolarizam e podem mobilizar sua força de trabalho independentemente da terra que possuíam, mas também, antes ainda, entre terra, capital e Estado. Nesse momento esteve também a escolarização no centro de um processo de suplantação da antiga iniciativa privada, com a espada nas mãos, por filhos ilustrados que se tornariam proprietários rurais rentistas e absenteístas e urbanizariam seus hábitos, formando a tecnocracia que permitiria a efetiva institucionalização do Estado no Brasil. Para conclusão do percurso, retornamos ao momento contemporâneo, então conceitualmente interpretado como desdobramento crítico daquele processo de autonomização, para situar os horizontes enfrentados pela escolarização diante da mobilidade do trabalho, hoje em crise.

A infância, entendida como “invenção moderna”, é permeada por processos culturais que incidem nos corpos infantes nos mais variados espaços onde estão inseridas. Nesse ínterim, uma multiplicidade de saberes técnico-científicos constrói verdades organizando os modos de compreensão da infância. Esta pesquisa foi realizada junto aos profissionais de educação de escolas públicas de um município do sul do Brasil a fim de compreender como ocorrem os processos de encaminhamento de crianças aos especialistas da área da saúde responsáveis pelo diagnóstico e tratamento biomédico de transtornos relacionados à infância. O diagnóstico e elaboração de laudos mostrou-se uma maneira rápida de resolver problemas que demonstram incômodo na escola, tais como agitação, falta de atenção, baixo desempenho escolar, transformando comportamentos indesejados em patologias. A problemática que está em questão não realizar um juízo de valor, mas repensar como práticas de medicalização se disseminam dentro e fora das escolas e que efeitos geram na construção de sujeitos e comunidades.
Doctors’ attitudes in the situation of delivering bad news: patients’ experience and expectations
Authors: Sobczak Krzysztof , Leoniuk Katarzyna
Published: January 2021

Introduction

The purpose of our research was to find out patients’ preferences concerning their doctors’ attitudes and behaviour as they deliver bad news to them.

Material and methods

In national research conducted from February to October 2017 using the CAWI (computer-assisted web interview) technique, we studied the statements of 314 adult patients who had received bad medical news from their doctors. Seventy-nine per cent of them were women and 21% were men. Fifty-nine per cent had higher education and 33% had secondary education. A specially designed closed question survey was used as a tool to collect the data.

Results

Most of the patients (59.6%) expected a doctor–patient relationship based on partnership and collective decisions concerning further treatment. Patients wanted their doctors to be honest with them, to provide them with solid information and an opportunity to ask questions and discuss the suggested solutions. Less than 2 out of 10 patients expected “an empathy specialist”. The patients who evaluated their doctors’ behaviour and the way bad news was delivered to them negatively were more likely to change doctors or terminate their treatment.

Conclusions

The doctor–patient relationship when an unfavourable diagnosis is being communicated is an important aspect, which defines the way people who participate in this difficult situation behave and communicate. Doctors’ behaviour during DBN should meet the patients’ expectations. Such an attitude guarantees trust towards doctors and results in more positive evaluations on them. Most importantly, it translates directly into the patients’ therapeutic behaviours and treatment effects.

Introduction

Myocardial infarction with non-obstructive coronary arteries (MINOCA), tako-tsubo cardiomyopathy (TTC), infective myocarditis (IM) and acute ST-segment elevation myocardial infarction (STEMI) of anterior wall being a heterogeneous group, may occur in very similar clinical presentations. In this study, it was aimed to compare the prognosis and identify predictors of major adverse cardiac and cerebrovascular events (MACCE) and all-cause mortality in these groups of patients.

Material and methods

At 2 Polish Academic Cardiology Centres among 596 patients, we compared clinical characteristics and outcomes in 4 groups: MINOCA (318, 53.3%), TTC (31, 5.2%), IM (22, 3.7%) and STEMI (225, 37.7%). MACCE were defined as myocardial infarction (MI), revascularisation (either percutaneous or surgical), all-cause death and stroke/transient ischemic attacks. Survival curves were presented using Kaplan-Meier estimator and compared using log-rank test.

Results

Kaplan-Meier survival analysis demonstrated that in the 3-year follow-up period, patients with anterior wall STEMI were at the highest risk of MACCE (p < 0.001). During the follow-up period, the greatest mortality rate was observed in the TTC group, however, this was without statistical significance. Multivariable regression analysis showed that long-term mortality was significantly related to age (p < 0.001), creatinine level (p < 0.001), platelet count (p < 0.001), white blood cells (p < 0.001) and hyperlipidaemia (p = 0.001).

Conclusions

During the 3 years of follow-up, anterior wall STEMI had significantly poorer prognosis in terms of MACCE when compared to the TTC, IM and MINOCA groups. TTC was related to the greatest all-cause mortality, however, without statistical significance.

Introduction

The nanoparticle has become a part of world industry. This substance has been proven as potentially beneficial for its usage as a catalyst and semi-conductor due to its high surface area and the effects of the quantum size effect. It exhibits potential characteristics and would be applied in a wider scope of usage compared to bulk particles because the smaller the size of the particles, the more room for the extent of their usage. Nano titanium dioxide application as semi-conductors together with a catalyst is highly attributed to its high photochemical stability and ability to be produced at a low-cost. The consequence of this – exposure of nano titanium dioxide particles to humans – raises concerns regarding health and safety. Therefore, this research action works designed to offer a thorough analysis of toxicology impacts produced by our own synthesis modified hydrothermal in vitro experiments.

Material and methods

Our nanotitania extraction with 0.05% silver was tested for its toxicity against L929 mouse cells. The cytotoxicity effect of nanotitania extract was evaluated by MTT assay. Cell viability (% CV) was calculated using a formula.

Results

There are non-cytotoxicity activity of 0.05% nanotitania at concentrations 1.5, 3.1, 6.3, 12.5, and 25 mg/ml on L929 cell lines except at concentration 50 and 100 mg/ml. The result was related to the optical density reading.

Conclusions

There is no cytotoxic effect of nanotitania extraction with 0.05% silver in the growth inhibition test with L929 mouse with the exception of the 100 mg/ml extract.

В данной работе с помощью одномерной самосогласованной аэрономической модели были получены высотные профили температуры, скорости и плотности для горячего нептуна GJ 436b. Мы проследили расширение газовой оболочки под действием нагрева от жесткого излучения родительской звезды от тонкого атмосферного слоя 1.02R 0 до 5R 0 . Используемая модель учитывает вклад надтепловых частиц, что значительно уточняет функцию нагрева атмосферы. Установлено, что формируется структура атмосферы с двумя характерными шкалами высоты, отвечающими относительно плотной атмосфере и более разреженной короне. Также был посчитан темп оттока атмосферы, составивший около 1.6 × 10 9 г с -1 , что ниже результатов, полученных авторами других расчетов.

In this work the height profiles of temperature, velocity, and density were obtained for the hot neptune GJ 436b, using a one-dimensional self-consistent aeronomic model. We traced the expansion of the gas envelope affected by heating from the extreme radiation of the host star from the thin atmospheric layer 1.02R 0 up to 5R 0 . The model used takes into account the contribution of suprathermal particles, which significantly refines the atmospheric heating function. It was found that the structure of the atmosphere is being formed with two characteristic altitude scales corresponding to a relatively dense atmosphere and a more rarefied corona. The atmospheric mass loss rate was also calculated, it was found to be about 1.6 × 10 9 g s -1 , which is lower than the results obtained by the authors of other calculations.
Astronomical climate of the telescope installation site and observation time loss

При выборе места установки оптического телескопа основными характеристиками являются статистика ясных ночей, и, впоследствии, статистика качества изображений, набираемая экспедиционными средствами. Поэтому интересно сравнить прогностические оценки с реальной статистикой уже работающего телескопа. По данным службы эксплуатации 6-метрового телескопа БТА оценивается количество наблюдательного времени и потери этого времени, связанные с метеоусловиями и техническими ограничениями на эксплуатацию комплекса БТА. Эти оценки могут быть использованы при планировании долгосрочных наблюдательных программ, в т.ч. и программы наземной спектроскопической поддержки проекта «Спектр-УФ».

When choosing a site for an optical telescope, the main characteristics are the statistics on clear nights, and, subsequently, the statistics on the seeing accumulated by the expeditionary means. Therefore, it is interesting to compare the predictive estimates with the real statistics of an already operating telescope. The data from the operation service of the 6-meter BTA telescope is used to estimate the amount of observational time, and the losses of this time associated with meteorological conditions and technical restrictions on the operation of the BTA complex. These estimates can be used in planning the long-term observational programs, including the programs for ground-based spectroscopic support of the Spektr-UV project.
Place of Culture in Relational Sociology
Authors: Hałas Elżbieta
Published: January 2021

Margaret S. Archer and Pierpaolo Donati have independently developed relational approaches in the social sciences. Combining morphogenetic theory and the relational theory of society opens up new research perspectives. This article attempts to investigate relational conceptions of culture by answering two questions: one related to the nature of culture and the other to the place of culture in relational sociology. Assuming the complementarity of the theories of both sociologists, the possibility that their conceptions may be inconsistent or even contradict each other is not discounted. The article discusses the issue of symbolization and the presence of processes of semiosis within relational sociology. It is argued that apart from the Cultural System and the Socio-Cultural interaction assumed by Archer’s analytical dualism, a more general category of Cultural Reality can be introduced. This theme is further discussed in the light of Donati’s views on human reality; he postulates including the relational frame of symbolization. Analysis shows that culture occupies a central place in relational sociology. This article exposes the complexity of the nature of culture in human reality.
