Published: April 2021

The increasing demand for energy and the concerns regarding environmental protection have been driving forces toward the exploitation of renewable energy sources as a better alternative compared to conventional energy sources. Furthermore, renewable energy sources enable an independent energy supply for isolated locations or communities that lack access to the main electricity grid, and additionally, they offer the possibility to use available energy sources for beneficial individual purposes. Considering these statements, the use of micro hydropower plants represents a convenient and advantageous option to implement. A micro hydro Turgo turbine is used for analysis in this paper, due to its simple design, structure, easy production and low installation cost.
In this manner, this paper deals with the use of Euler equations in detailed analysis in designing and implementation of a micro hydro Turgo turbine. The presented methodology will be based on numerical calculations of micro hydro Turgo turbine characteristic parameters in various operating regimes. The obtained results from numerical calculation will be compared to the current performance of the real existing Turgo turbine. Accordingly, based on obtained results, recommendations for improving the performance of micro hydro Turgo turbines will be presented.

G. Finlay, “Michael Panaretos’un kronikleri Profesör Fallmerayer tarafından bulunmadan önce Trabzon’un tarihi hakkında neredeyse hiçbir şey bilinmiyordu” diye yazar. Bu kroniklerin ortaya çıkması ile bir yandan 1204 yılında kurulan Komnenos Devleti’nin tarihi aydınlanmaya başlarken, diğer yandan tüm bölgenin tarihine karşı olan ilgi giderek büyümüştür. Böylece, 19. yüzyıl boyunca eski kaynaklarda geçen Trabzon ve çevresiyle ilgili tüm bilgiler bir araya getirilmeye başlanmıştır. Bu çabaların sonucunda artık Trabzon’un bir “Hellen kolonisi” olarak MÖ 1. binyılda tarih sahnesinde yerini aldığı yargısı ortaya çıkmıştır. Günümüzde artık Trabzon tarihiyle ile ilgili “neredeyse hiçbir şey bilinmiyor” demesek de, kent tarihiyle ilgili bilmediğimiz daha çok şey olduğu açıktır. Bu yazınınana konusunu her ne kadar 2018 yılında kent merkezinde yapılan arkeolojik yüzey araştırması sırasında biraz da tesadüfen inceleme fırsatı bulduğumuz ve“Hadrian Limanı” diye anılan yer oluşturmaktaysa da, bunu fırsat bilerek Ksenophon’dan itibaren Trabzon tarihiyle ilgili söylenip yazılanların çoğu bir kez daha elden geçirilmiştir. Bu sayede Karadeniz’in güneydoğu kıyısındaki bu ünlü kent ve eski limanı ile ilgili dimağlardaki bilgiler masaya yatırılmıştır.

Published: April 2021

Today, memorable experiences are the leading economic value proposition that the tourism industry holds. This article aims to theoretically investigate the relationship between the senses, emotions and memories in the tourist experience and present a conceptual model about the senses, emotions and memories in the tourism experience establishment. Based on the literature review, we concluded that the construction of the tourism experience is the result of multi-sensory stimuli and perception, positive emotions, high emotional states, surprising events, extraordinary moments and pleasant and positive memories. It was also found that the senses, emotions and memories have a sequential relationship in the tourism experience establishment. We also concluded that the senses paly a important role in the experiential stimuli perception, the emotional states are vital to the stimuli interpretation and meaning achievement and memories are essential to coding, storage and anticipation the experiential information.

Published: April 2021

Durante el Cretáceo Superior, el margen noroccidental de Suramérica se caracterizó por presentar un ambiente tectónico complejo, representado por la acreción de múltiples terrenos y la generación de varios eventos magmáticos. La cuarzodiorita de Sabanalarga y el Gabro de Santa Fe, anteriormente descritos como una única unidad denominada “Batolito de Sabanalarga”, presentaban múltiples diferencias entre sí y hoy son considerados dos plutones independientes, exponiendo dos de los eventos magmáticos del cretáceo superior. Ambos plutones emplazados en cortezas de diferente afinidad; el Gabro de Santa Fe emplazado en corteza tipo Plateau y arco de islas, mientras que la cuarzodiorita de Sabanalarga es emplazada en corteza continental del Complejo Cajamarca. Los análisis químicos de roca total realizados, presentaron anomalías de Nb-Ti, patrones de HFSE y REE en los diagramas multielementales característicos de rocas generadas en ambientes de subducción. El gabro de Santa Fe presenta características adakiticas no presentes en la cuarzodiorita de Sabanalarga. El bajo contenido Zr y relaciones (La/Yb)n vs Sr/Y < 10 sugieren que el magma del Gabro de Santa Fe fue formado en ambiente oceánico, contrario a la cuarzodiorita de Sabanalarga con alto Zr y relaciones (La/Yb)n vs Sr/Y > 10 que sugieren para este magma un origen en un ambiente continental. Se realizaron análisis U-Pb LA-ICP-Ms para ambos intrusivos: el Gabro de Santa Fe presentó edades entre 78.4 y 81.8 Ma y la cuarzodiorita de Sabanalarga edades entre 71.5 y 76.7 Ma. A la luz de los nuevos datos geoquímicos y geocronológicos se sugiere en este trabajo que el Gabro de Santa Fe y la cuarzodiorita de Sabanalarga son dos cuerpos diferentes sin relación temporal y cuya relación espacial es todavía debatible. Para el ambiente de formación de estos plutones se sugiere un modelo de doble subducción tipo Molucca.

This study investigates the pool boiling heat transfer of water over cylindrical heating tubes for different orientations and surface roughness of the tubes. First, two orientations of a smooth heating tube, horizontal and vertical, were used in the boiling chamber. For a given heat flux, the heat transfer coefficient achieved with the horizontal tube was always higher than that for the vertical tube. To investigate the influence of surface roughness, a rough heating tube with a fully rough outer surface was developed through a metal etching process. Under the same range of wall superheat, the rough tube enhanced the heat transfer rate significantly compared to the smooth tube. Finally, a modified heating tube (MHT) was developed by axially roughening half of the surface of an originally smooth tube. The orientation angle of the rough surface of this MHT was varied from 0° (horizontal-upward) to 180° (horizontal-downward) in the chamber. The heat flux increased significantly with the increase of orientation angles from 0° to 90° (the maximum of 80 kW/m2 at 90°), whereas the same decreased as the orientation angle is further increased from 90° to 180°. Results revealed that the bubble dynamics over the heating tubes play a vital role in pool boiling performance.
Investigation of Thermo-Hydraulics Flow and Augmentation of Heat Transfer in the Circular Pipe by Combined Using Corrugated Tube with Dimples and Fitted with Varying Tape Insert Configurations
Authors: Al-Obaidi Ahmed Ramadhan , Alhamid Jassim
Published: April 2021

In various industrial applications, the high performance of heat exchanger demand is increasing. Subsequently, the energy resources depletion, for instance, in power plant, air-conditioning system and food processing systems. The important field for saving energy was through improving thermal performance, which can provide high performance heat exchanger. Present enhancing approaches can be classified by three changed types, which are passive technique, active technique and compound technique. Dimple, twisted tape and corrugated pipe are the passive heat improvement technique which includes more surface extensions. Hence, this research work concentrates on verifying the computational calculations of flow in the heat exchanger pipe with different surface extensions in the pipe. It is carried out for turbulent flow with a range of Reynolds number from 1000 to 15000 using CFD methods. The numerical outcomes illustrate that change twisted tape configurations have more effect on flow and heat performance. Experimental and numerical results agreement can confirm the simulation technique reliability, which adopts in this investigation. The deviation errors are observed by less than 6% compared with the normal pipe. Pressure drop increases due to the rise of twisted tape dimensions (width and thickness), leading to more mixing of fluid, secondary flow, and swirl flow inside the pipe. As the tape geometrical parameters increase, the f value also increases due to more variance in velocities flow between liquid layers, which are adjacent to tape surfaces a pipe wall, and pipe core flow layers, become higher. Correspondingly, compared to the normal pipe, twisted configurations can rise f about 5.4 to 33.5%. The better thermal evaluation factor is at a twisted tape of 1x1 mm at Re number of about 1000. The range value of the thermal evaluation factor is more than 1.67.
Design and Numerical Simulation of In-Situ Pyrolysis of Oil Shale Through Horizontal Well Fracturing with Nitrogen Injection
Authors: Jiang Pengfei , Zhang Danlei , Li Bin , Song Chao
Published: April 2021

An in-situ pyrolysis technology was proposed for shallow oil shale: drilling horizontal wells to the oil shale formation, connecting the horizontal well sections through hydraulic fracturing, injecting nitrogen from the surface to bottomhole, heating up the nitrogen to a high temperature at the bottom, and directly using the high-temperature nitrogen for oil shale pyrolysis. Then, a mathematical model was established for the heat transfer within the oil shale, and a simplified physical model was created for in-situ pyrolysis of oil shale, and used to simulate the heat transfer process. The simulation results show that, with the extension of heating time, the area of effectively pyrolyzed oil shale formation took up an increasingly large proportion of the total cross-sectional area of the formation; however, the increase of the pyrolysis area ratio was rather slow, and the temperature was unevenly distributed in the formation after a long duration of heating. Therefore, the 300d in-situ heating was split into two stages: 250d of heating in the heating well and 50d of heating in the production well. The two-stage heating maximized the heating area of oil shale, and heated 57% of the cross-sectional area up to 400℃, ensuring the effectiveness of pyrolysis. Moreover, this heating scheme ensured an even distribution of temperature in oil shale formation, a high energy utilization, and a desirable heating effect.

Published: April 2021

This paper presents an experimental analysis on the heat transfer and pressure drop enhancement of oil nanofluid flow. In this analysis, the first method has used the helically coiled tube and shell, the oil nanofluids were employed instead of the base fluid (oil) in the second process. the two techniques were used to improve the heat transfer and pressure drop. Nanofluid oil concentrations utilized within range from 1 to 5 percent vol. This paper applied two forms of nanoparticles: copper (Cu (20 nm)) and zirconium oxide (ZrO2 (40 nm)) and base fluid (oil). The influence on the heat transfer coefficient for different factors such as the flow number of Reynolds, the temperature of the nanofluid oil, the concentration and shape of the nanoparticle, and the pressure gradient of the flow have examined. The results indicated that the value of a 40.35 percent in the heat transfer coefficient for Cu + oil and 28.42 percent for ZrO2 + oil increased compared with the base fluid (oil) at 5 percent vol concentration. Using oil nanofluids (Cu, ZrO2 – oil) instead of the base fluid (oil) led to increasing in the heat transfer coefficient and decreasing the pressure. In addition, the result showed that the heat transfer efficiency has enhanced using the helically coiled tube and shell, as well as increasing in the pressure drop was due to the curvature of the tube. Baes on the relationship between viscosity and shear intensity, the oil nanofluid behaviors were similar to the standard Newtonian fluids. Moreover, the related flow and heat transfer methods are used to present the output index. The exergy inflow, exergy destruction and exergy efficiency of oil nanofluid (Cu +oil) were greater than the oil nanofluid (ZrO2 +oil) and oil. The exergy inflow, exergy destruction, and exergy efficiency for the two type of oil nanofluid increased with increasing of nanoparticles concentration.

The volume “Building bridges: Promoting wellbeing for family. Handbook for parents ”, published by Lumen Publishing House from Iași in 2018, was developed within the project “Building bridges: Promoting social inclusion and well-being for the families of children with special needs (PSI-WELL)”, and is the result of a cross-sectional and transnational study on social inclusion, stress levels and the well-being of families with children with special needs, carried out in each of the 6 countries that were partners in the project (Romania, Spain, Portugal, Croatia, Turkey and Lithuania). The volume coordinated by Assoc. Prof. PhD. Aurora Adina Colomeischi provides concrete results of the extensive research undertaken within the project and seems to be a viable starting point for the development of an educational policy for parents and families of children with special needs. The work is very well substantiated scientifically, and is especially useful for parents who face the special needs of their children, but also for the specialists who undergo therapy with them. In our opinion, the book deals with desirable aspects in the development of social intervention programs often aimed at parents with children with special needs, programs dealing with improving personal resources and parenting skills needed to solve various special and difficult situations presented by children.
Industrijska revolucija 4.0 v HRM
Authors: Požarnik Lovro , Jug Nina
Published: April 2021

Globalizacija in razvoj spletne tehnologije ne spreminjata vse bolj samo klasične poslovne procese, ampak tudi kadrovske procese v dinamične procese, ki se vse pogosteje odvijajo v različnih časovnih okvirih, na različnih koncih sveta ter tudi v različnih vrstah in oblikah dela. Tretja industrijska revolucija, ki se je začela razvijati v osemdesetih letih prejšnjega stoletja je pomembno vplivala na vsakodnevne kadrovske procese v podjetjih po vsem svetu. Pionirska podjetja, ki so sprejela digitalizacijo in vključila digitalne kadrovske rešitve, so imela veliko prednost pri nadaljnjem razvoju in rasti. O pozitivnih vplivih »Interneta stvari« (ang. »Internet od things« oz. IoT) in umetne inteligence (ang. »Artificial intelligence« oz. AI) se je začelo govoriti že na Svetovnem gospodarskem forumu leta 2016, kar samo podpre dejstvo, da je nova industrijska pred vrati. Četrta industrijska revolucija, 4.0, predstavlja za Slovenijo drugo veliko razvojno priložnost – ampak samo, če bomo digitalno transformacijo sprejeli tudi v praksi in jo temu ustrezno tudi finančno ter kadrovsko podprli. V vse hitreje razvijajočem se digitalnem okolju pa žal še vedno obstajajo podjetja, ki zaostajajo pri implementaciji digitalnih kadrovskih rešitev. Razlogi zato so različni, vse od finančnih omejitev, nezaupanja tehnologiji in upora vodstva. Kljub temu se pa trendi digitalnega kadrovanja vse bolj opazni tako v vsakodnevnem poslovanju kot tudi v zaposlovanju in usposabljanju zaposlenih. V predlaganem prispevku smo se osredotočili na sam trend digitalizacije in izpostavili orodja, ki jih nekatera podjetja že uporabljajo: brezpapirno poslovanje, aplikacije za beleženja časa, avtomatizacija procesov, zaposlovanja preko socialnih omrežij, uporaba VR tehnologije za uvajanje in izobraževanje, t.i. »gaimification« na delovnem mestu.

Published: April 2021

Processes are one of key elements of each organization, so their analysis and constant improvement is essential for developing and maintaining competitive advantage. Business process mapping represents the initial step in process optimization. Another important aspect of good market position and business success is customer satisfaction. Organizations that are customer-oriented have much higher chance for satisfying and retaining their customers. Steel production industry is specific for extremely large and expensive orders on one hand, and production limits in terms of dimensions and quality on the other hand. In this industry clients are expected to accept certain adoptions of their demands in cases of production to order, or to adapt to predefined portfolio in cases of production in advance. Production to order in steel industry is more difficult to organize and increases production costs, but this approach improves customer orientation and eliminates the risk of unsold goods. However, order optimization is the step that can endanger customer satisfaction within sales and negotiation process in such production. This paper will show how process mapping and analysis as a tool in organizational design can represent a base for process flow optimization that increases process efficiency but also improves customer orientation, leading to competitive advantage.

Developing the Credit Score Model Through the Common Use of Financial and Qualitative Indicators in the Evaluation of Creditworthiness
Authors: Vareško Andrea
Published: April 2021

The developed credit score model represents an innovative and advanced way in the credit rating process that uses both financial and qualitative indicators in estimating creditworthiness. in order to develop the model a research has been carried out in the croatian banking sector and among the consulting companies involved in the process of creditworthiness. the model has been developed based on the findings and conclusions from the conducted research and contributes in the economic science, specifically in the field of innovation and competitiveness. The balance sheet data and the indicators originating from the financial statements can be used to determine how a company was performing in the past and how successful it was. But this information tells us very little about the quality of management, market share, company plans, production process, organizational structure, etc. and nothing about the directions in which the company is developing. This means that during the process of evaluation of creditworthiness a risk analyst needs much more information than the annual financial statements can provide. That is why qualitative factors must be also considered when estimating creditworthiness. The aim of this paper is to research the importance of the common use of the proposed qualitative and financial indicators in the process of estimating creditworthiness, and, in addition, to propose a model based on the resulting research findings. In the proposed credit score model, the final credit rating is determined by the synthesis and common scoring of financial and qualitative indicators, which ultimately reflects internal and external factors that directly affect the operations of any business entity. The proposed model will certainly allow a simpler and better rating score of small, medium and large companies, and with its simplicity it will contribute to the analysis of each business entity. In the model itself, the optimal choice of financial and qualitative indicators and their weighted values were used to make a more reliable credit rating score considering the internal and external factors affecting the business. Determining credit rating by applying financial and qualitative indicators provides comprehensive and credible information about the business entity and its business risks and thus allows the making of punctual and correct business decisions, i.e. wrong business decisions are prevented.

Cilj raziskave je predstaviti aktivnosti društev, ki povezujejo ljudi s posebnimi potrebami, povezane s prostočasnimi dejavnostmi s poudarkom na turizmu. V to skupino vključujemo invalide, slepe in slabovidne, gluhe in naglušne ter druga društva za pomoč ljudem s posebnimi potrebami. Danes se vsi srečujemo s prostočasnimi dejavnostmi in potovanji. Vanje in na potovanja pa se vključuje tudi vse več ljudi s posebnimi potrebami. To v preteklosti ni bil množičen pojav. Namen tega prispevka je raziskati tematiko, ki izhaja raziskovalnega vprašanja, kjer smo ugotavljali, kako društva ljudi s posebnimi potrebami organizirajo prostočasne dejavnosti in kako člani le-te sprejemajo. Izvedli smo namizno in terensko raziskavo. Ugotovili smo da društva za svoje člane organizirajo številne dejavnosti. Poleg prostočasnih tudi turistične dejavnosti. Člani pa so zelo aktivni in niso izrazito zahtevni. Prednost je tudi, da potujejo izven glavne sezone in da predajajo informacije do drugih od ust do ust. Zato je priporočilo, da bi se morala ta ponudba še bolj dopolniti in se tržno naravnati tudi na tuje turiste.

Published: April 2021

Background: The microbial evolution of the J’ben Elgafs prepared with raw milk from local cows, was studied during the manufacturing and maturating process in order to characterize this variety of cheese from the Algerian terroir. Methods: The microbial activity and physical-chemical parameters were tested during the three dairy seasons of the year. Total, lactics and alteration floras were counted on their selective environments. Result: Lactic germs multiply considerably during the first days and only stabilize towards the end of maturation. The low presence of alteration floras is the result of the continuous modification of the physico-chemical parameters of Aw and pH from one stage to the other of the j’ben production and the respect of good processing practices. These different proportions of variation are induced by the biochemical reactions and microbial interactions that take place responsible for the sequential growth of one microbial group compared to another.

Structuring of Political Space in European Union (the end)
Authors: Strezhneva M.
Published: April 2021

Emergence of the EU political system led to the denationalization of its economic space. This political system can be characterized as a democratic one. Yet through European elections, the European citizens do not elect the government acting at the supranational level. It is not them, but the European political class, who determines the integration agenda. The article exposes а linkage between changing parameters of political democracy in the EU member states and transition from centralized national governance to a multilevel one (MLG), accompanied by development of new governance modes. Participatory democracy serves in the EU as an important supplement for representative democracy. Privileged partners (such as Switzerland or Norway) are allowed to participate in the MLG. Yet representatives of the transnational European civil society or governments of those states, which are not full EU members, are not admitted to the decision-making stage.
North European Countries: Rapproachment of Geopolitical Lines
Authors: Voronov K.
Published: April 2021

During the post-bipolar period, the elimination of external pressure and super powers' infighting, cessation of the arms race intrinsically furthered rapproachment of military-political interests and geopolitical lines of the subregional states which adhered to multifold security models, bloc and integration policy. The report of J. Stoltenberg (the former Foreign Minister of Norway), the statements of which have already been implemented in practice, became an important milestone of this considerable progress. The Nordic Defence Cooperation will be better organized politically, coordinated and more effective as a result of some national structures' amalgamation. Even if any new military-political formation in the subregion will not emerge soon, the further cooperation reinforcement in this sphere may lead to essential change in the defence and security field.
APRENDIZAGEM PAUTADA NA AFETIVIDADE

A afetividade é essencial no ensino-aprendizagem. O aluno se desenvolve participando de um jogo de relações mútuas entre professor-aluno, aluno-aluno, aluno-conteúdo. E no bojo destas relações deve existir a empatia, a tolerância, o respeito e a atenção ao outro, como um sinônimo de motivação e de interesse em superar as várias lacunas da educação. E a Geografia na sua crise contemporânea necessita fazer parte do circuito de afetividade, supor o ensino pautado nas relações sociais que são infinitas e se inserem no espaço. Para isto, este artigo propôs discutir sobre o ensino, afetividade e a geografia escolar, buscando reconhecer qual a importância da afetividade para a aprendizagem. Para vencer este objetivo, utilizou-se a pesquisa bibliográfica, conduzida por uma rica revisão de literatura que permitisse alcançar a preposição da abordagem e contribuir com os pensamentos e análise sobre a educação, especialmente o aprender a Geografia em sala de aula.

Authors: Moraes Ewandelina de , Souza Lucas Barbosa e
Published: April 2021

O presente trabalho traz reflexões sobre a percepção dos riscos de inundações com ênfase na vulnerabilidade socioambiental das famílias do Setor Jardim Querido, em Porto Nacional – TO. Foram discutidos antecedentes teóricos, englobando especialmente a questão da justiça ambiental. Quanto aos aspectos metodológicos, tratou-se de pesquisa perceptiva, tendo sido realizadas entrevistas semiestruturadas junto às pessoas, em suas residências. Os resultados indicaram, de modo geral, as dificuldades das famílias para lidar com o risco, a falta de uma compreensão clara sobre os condicionantes de risco no local e uma percepção negativa a respeito da atuação do poder público junto à comunidade. Assim, almeja-se que os apontamentos provindos deste estudo sirvam de subsídio ao planejamento de políticas públicas, aos responsáveis pelo monitoramento e ordenamento territorial da cidade, sempre voltados à sustentabilidade e melhora da qualidade de vida da população.
IGREJA ASSEMBLEIA DE DEUS

Published: April 2021

A Igreja Assembleia de Deus sempre caracterizou pelos seus padrões rígidos de comportamentos, mas, com o passar do tempo vem mudando gradativamente suas condutas, pois, os novos pastores assembleianos vêm sustentando mais como uma questão de costume do que de doutrina, visto que não interfere na fé cristã. O presente estudo objetiva-se realizar uma análise etnográfica de um culto da Igreja Assembleia de Deus, no município de Pirapora-MG e compreender a doutrina das práticas e as tendências culturais, além de realizar uma descrição das práticas e costumes assimilados e professados pelos pastores e seus fiéis. Para obtenção dos objetivos foram realizados levantamentos de literatura específica sobre as características, origem e desenvolvimento histórico da Assembleia de Deus no Brasil, além de uma visita na igreja para percepção e registros de um culto. Os procedimentos metodológicos adotados foram baseados na etnografia, que é o método próprio de trabalho da antropologia. Percebe-se ao longo do trabalho que a doutrina dos usos e costumes é um dos principais diferenciais da identidade dos membros da Assembleia de Deus e que estudos e reflexões futuras pode corroborar a realidade desta comunidade.

Atualmente, violência e criminalidade violenta são fenômenos bastante alarmantes que têm despertado preocupação de diferentes segmentos da sociedade, se apresentam como sérios problemas endêmicos, de saúde pública, uma vez que suas consequências atingem todos os indivíduos, indistintamente. Nesse contexto, este trabalho objetiva analisar a evolução espaço-temporal das ocorrências dos crimes violentos, geradores de insegurança pública, no Estado de Minas Gerais e na Mesorregião Norte de Minas, no período de 2012 a 2018. A abordagem metodológica privilegiou um estudo de caráter analítico-descritivo à luz de literatura especializada sobre o tema, bem como coleta de dados quantitativos do Instituto Brasileiro de Geografia e Estatística (IBGE, 2019) e dados do Registro de Eventos de Defesa Social/Secretaria de Estado de Segurança Pública (REDS/SESP/MG). Os resultados sugerem que os crimes violentos não ocorrem aleatoriamente no tempo e no espaço e que os números de registros de ocorrências e/ou taxas de crescimento e de crimes por 100 mil habitantes, tanto em Minas quanto na Mesorregião Norte de Minas, são correlatos à concentração de população, acelerado processo de urbanização, indicadores socioeconômicos, privações e desigualdades, além de deficiência de infraestrutura e facilidade de acesso às redes de comunicações e ao tráfico de drogas ilícitas.

Published: April 2021

O Sínodo para a Família, convocado pelo Papa Francisco em 2013, ainda no primeiro ano de seu pontificado, trouxe a novidade de se dividir em duas Assembleias Gerais, celebradas em 2014 e 2015. O tema norteador foi “A vocação e a missão da família na Igreja e no mundo contemporâneo”. O último sínodo sobre esta temática tinha sido em 1980, cujo fruto foi a Exortação Familiaris Consortio (1981), de João Paulo II. Mais de três décadas depois, viu-se como necessário afrontar a realidade das famílias, em tempo de tantas mudanças, na sociedade e na Igreja (…)
Fighting Deepfakes Using Body Language Analysis

Published: April 2021

Recent improvements in deepfake creation have made deepfake videos more realistic. Moreover, open-source software has made deepfake creation more accessible, which reduces the barrier to entry for deepfake creation. This could pose a threat to the people’s privacy. There is a potential danger if the deepfake creation techniques are used by people with an ulterior motive to produce deepfake videos of world leaders to disrupt the order of countries and the world. Therefore, research into the automatic detection of deepfaked media is essential for public security. In this work, we propose a deepfake detection method using upper body language analysis. Specifically, a many-to-one LSTM network was designed and trained as a classification model for deepfake detection. Different models were trained by varying the hyperparameters to build a final model with benchmark accuracy. We achieved 94.39% accuracy on the deepfake test set. The experimental results showed that upper body language can effectively detect deepfakes.

The novel coronavirus has had the world on halt for a few months now. Changes in lifestyles have become a part and parcel of our daily lives, especially for students. With new teaching practices undertaken, new reforms are being made from students in kindergarten to college. This paper presents insights on the changing learning habits of Indian students due to the hit of novel coronavirus (COVID-19). A total of 648 students from various institutes took part in the survey by responding to the questionnaires on time spent by them both for online and offline studies and others asked in closed format options. The insights are derived by comparing the performance of students based on their institute types, hours spent on self-study as well as the assistance provided by the colleges. The overall confidence in particular subjects by the end of the semester is being determined as the end result.

Abstract: Targeted ubiquitination and proteasomal degradation regulates various cellular pathways, and the discovery that CPT induced rapid proteasomal degradation of topoI is the primary mechanism of CPT resistance was novel and compelling. CPTs are used extensively to treat various solid tumors like colorectal, gastric, pancreatic, ovarian and small cell lung cancer. The response rate is low and the classical mechanisms of drug resistance are yet to be validated. Remarkably, CPT resistant cells degrade topoI rapidly by UPP and recently we’ve published the molecular determinants of this pathway. To further understand the UPP mediated CPT resistance mechanism we used targeted proteasome prohibition by ixazomib (MLN9708) to stabilize topoI and determine its impact on CPT resistance. CPT resistant and sensitive cancer lines were both treated with ixazomib in combination with CPT. The CPT induced rate of topoI degradation, and its stabilization by ixazomib, was visualized and estimated by immunohistochemistry, immunofluorescence and immunoblotting assays, MTT and subG1 assays provided the drug sensitivity. Our results demonstrate that cells that degrade topoI rapidly are very resistant to CPT, and ixazomib significantly inhibits CPT induced topoI degradation. Notably, inhibition of proteasomal degradation by ixazomib overcomes the drug resistance and sensitizes the cells for CPTs.
