INFLUENCE OF FAST PYROLYSIS WITH TEMPERATURE ON GAS, CHAR AND BIO-OIL PRODUCTION
Authors: KLUNK Marcos Antônio , DASGUPTA Sudipta , DAS Mohuli
Published: May 2021

Rice husk is among the products that stand out in use, and it is used as an alternative source of energy. The use of rice husk as biomass in the feeding of pyrolytic reactors for power generation and chemical products can reduce the environmental problem destination of this waste. The advantages of this process are in the proper disposal of this waste and energy generation. Fast pyrolysis of the rice husk was carried out in temperatures of 400-600°C. This work aims to evaluate the influence of temperature on yield and product composition of the gas, bio-oil, and char. The yield of bio-oil proved to be efficient (62 wt.% at 450°C) due to the high heat transfer and mass, as well as the residence time in the reactor. In addition, bio-oil production decreases slightly due to increased gas yield (1 to 15 wt.%) as the temperature increases in the range of 400-600°C, with the composition being severely affected, i.e., The concentration of CO increases and that of CO2 decreases. In addition, a slight increase in the concentration of CH4 and C2-C4 hydrocarbons occurs with increasing temperature. The yield of char at 400°C and 600°C was 41.14-34.77 wt.%, respectively, corresponding to a decrease of 16 wt.%. The char obtained is of low heating value but has good features for the production of active carbons and amorphous silica. These results demonstrate the efficiency and optimization of the fast pyrolysis of rice husk, in order to obtain biooil and char.

Authors: AGNOLETTO Douglas , LEMOS Guilherme Vieira Braga , BESKOW Arthur Bortolini , LESSA Cleber Rodrigo de Lima , REGULY Afonso
Published: May 2021

Cast iron alloys combine many elements such as carbon, iron, silicon, magnesium and can be usually classified according to their microstructure in ductile, gray, compacted, white, and malleable. Each one has particularities in terms of properties and applications. Hence, this study aims to evaluate the degree of nodularity (%) in a ductile cast iron alloy GGG 40. In this context, a methodology to investigate the degree of nodularity was proposed. The ultrasonic method was used to determine the amount of ductile graphite as well as for parts release and thus facilitated the industrial operational execution. The effect of ultrasonic sound was investigated in sixty-seven ductile cast irons, and these analyses were further compared to the level of nodularity observed by metallography. Finally, based on the findings, the cast iron quality was guaranteed, leading to time savings, avoiding the microstructural examination, and thus promoting cost reductions.

Authors: KUPATADZE Ketevan
Published: May 2021

The article reviews the chemical composition of borehole and surface waters in three villages of one of the regions of Georgia - Kakheti, Gurjaani Municipality. The study was specifically focused on iodine content in waters. It turned out that certain amount of iodine really existed in borehole waters, which means that by everyday drinking of water, the human body gets maybe not the complete required amount of iodine, but at least some part of it. It was also discovered, that according to certain parameters, waters are clean, do not contain heavy metals and can be freely used for drinking and cooking. The chemical composition of the Alazani River was also examined according to all four seasons. This river is interesting because of being used for irrigation of vineyards and fruit gardens.

Authors: Twaliwi Christy , Ugwuanyi Georgina Obinne , Efanga Udeme Okon
Published: May 2021

The major goal of this research was to see how budget assessment affected Nigeria's economic progress. The inspiration stemmed from a number of inconsistencies in the Nigerian economy's budget preparation and execution. This study employed an ex-post-facto design, with data gathered from the Central Bank Statistical Bulletin and the Federal Ministry of Finance for analysis. A model based on empirical and theoretical reviews was developed to attain this wide purpose. The model's dependent variable was the Human Development Index (HDI), while the model's independent variables were the government's capital budget, recurrent budget, and yearly budget implementation rate. To evaluate data, the researchers used the Ordinary Least Squares (OLS) Model. Budget assessment had a favorable and considerable influence on Nigeria's economic progress, according to the inferential findings. According to the report, Nigeria's government should make an effort to raise capital and recurring expenditures in its yearly budget, since both have a substantial influence on economic development. Finally, the government should make an effort to put in place effective budget monitoring and assessment equipment that will increase the rate of budget implementation while simultaneously ensuring strict adherence to due process.

There are 65 million people who have access to the wheelchairs and about 80% requires another person to help them commute from one place to another. So, why is there a need of another person to help the disabled? We have prepared this wheelchair that works according to gestures of hand. An accelerometer is used as a sensor which gives an analog signal on its movement in any of the 6 axis directions, that is positive X axis, negative X axis, positive Y axis, negative Y axis, positive Z axis, negative Z axis. In this project we have considered X and Y axis for the direction. The Arduino continuously acquires data from the accelerometer and based on the predefined parameters, it sends a data to the NRF24L01 Transmitter. The data transmitted from transmitter is received by paired NRF2401 receiver, the data received from transmitter are processed by the arduino and appropriate signals are sent to motor driver which will activate the wheels of the motor.

Terms such as “charge” and “oxidation state” appear frequently in the literature. The problem is that they are often viewed to be synonymous. However, they are fundamentally different concepts using distinct notations. The aim of the present discussion is to attract the attention of researchers from various fields of science in order to prevent further use of misleading interpretations.
O filme “Guerra dos Mundos” (1953) e as Percepções sobre a Ciência e o Trabalho Científico na Guerra Fria
Authors: Silva Renan Siqueira da , Moura Breno Arsioli
Published: May 2021

Em 1953, foi lançado o filme Guerra dos Mundos, uma adaptação do romance homônimo de H.G. Wells, publicado em 1898. Neste artigo, analisamos como esse filme refletiu a tendência de valorização da ciência no período em que foi lançado, impulsionada pelas disputas políticas e militares características da Guerra Fria. Em um primeiro momento, apresentamos um panorama historiográfico sobre anos iniciais da Guerra Fria, especialmente sobre os desenvolvimentos científicos surgidos a partir da década de 1950 e o crescente enaltecimento da ciência que deles emergiram. Em seguida, mostramos como algumas cenas do filme Guerra dos Mundos (1953) reforçaram essa valorização, ao reposicionar o cientista de coadjuvante a protagonista em relação à obra original de Wells e ao ressaltar uma visão indutivista da ciência. A partir desse estudo teórico, acreditamos ser possível fornecer subsídios para atividades de ensino na interface entre história das ciências e cinema.

Published: May 2021

Investigamos a experiência de cinco grupos de adolescentes ao visitar a Feira de Ciência, Tecnologia e Inovação do Estado do Rio de Janeiro (FECTI) com o objetivo de analisar a dinâmica dos visitantes nesse espaço, em particular, como eles interagiram com os expositores, os objetos expositivos e entre eles. A coleta de dados foi feita com câmeras subjetivas acopladas em um adolescente por grupo e os vídeos foram analisados com um protocolo de pesquisa que permite revelar os tipos de conversas e interações mais frequentes durante a visita. Identificamos que, se por um lado os visitantes se apropriaram de forma participativa da feira de ciências, escolhendo e negociando temáticas científicas de interesse a partir de experiências e conhecimentos prévios do/sobre o grupo e envolvendo esforços criativos para entender, contribuir e se integrar à dinâmica da feira; por outro, pouco foram os casos em que foi possível identificar conversas em que eles se mostraram engajados em conteúdos de ciência na relação com os expositores da feira. Esses resultados podem ser um indicador da necessidade de pensar outras dinâmicas e formatos de feiras de ciências para envolver os visitantes.

ЕКСЦЕНТРИЧНА АКРОБАТИЧНА ПАРА ЯК ФЕНОМЕН СУЧАСНОГО ЦИРКОВОГО МИСТЕЦТВА (НА ПРИКЛАДІ ДУЕТУ «DUO FLASH»)
Authors: BITKINE Yefrem
Published: May 2021

Сучасне циркове мистецтво України історично пов’язане з діяльністю і акробатів-скоморохів, і перших професійних артистів циркових труп. Особливе місце посідають акробатичні пари. Окремо виділимо саме ексцентриків, коміків. Неоціненним досвідом для молодого покоління циркових артистів в акробатичному жанрі є досягнення братів Олександра та Василя Ялових, подружжя Пастухових, братів Маренкових, братів Дякових та ін. Вони стояли біля витоків циркового акробатичного мистецтва ще радянської України. Спорт і мистецтво цирку завжди доповнювали один одний у розвитку акробатики як у манежі, так і на спортивних майданчиках. Тісний зв’язок спостерігається і в творчій діяльності сучасних циркових артистів-акробатів, а саме, серед стрибунів у групових номерах, чоловічих та змішаних парах, жіночих трійках або в чоловічих четвірках, в інших видах акробатичного жанру. На сьогодні є багато прикладів саме акробатичних шоу або вистав у світовому цирковому мистецтві.

Акробатична вистава в цирку є актуальною та сучасною формою видовища. Головною дієвою особою вистави  є артист-акробат, який володіє різними видами цього жанру. Вистава за своєю формою може бути дивертисментом, шоу, ревю, виставою з драматургічним сюжетом.

До найзначніших феноменів сучасного українського циркового мистецтва сьогодні можна віднести акробатично-ексцентричну пару «Duo Flash», яка має понад 20 років історії. Дует є не тільки самостійним явищем циркового простору України, але і має особливе значення для позиціонування сучасного українського цирку за межами країни, тобто виконує важливу функцію покращення іміджу України у світовому культурному полі, є інструментом побудови міжкультурного діалогу. Учасниками дуету є Єфрем Біткіне та Євген Дашківський, представники циркових династій, випускники Київської муніципальної академії естрадного та циркового мистецтв. Дана розвідка присвячена основним періодам їх творчої біографії (київському, німецькому іспанському), становленню як акробатичної пари, взаємозбагаченню традицій різних циркових шкіл на їх прикладі.
НЕОФОЛЬКЛОРНІ ОСОБЛИВОСТІ ТВОРЧОСТІ ВАЛЕНТИНА ГОРДІЙЧУКА ТА АНАТОЛІЯ ТОКАРЕВА
Authors: ZAITSEVA Veronika
Published: May 2021

Досліджуючи та аналізуючи художню спадщину українських графіків ІІ пол. ХХ ст., можемо зазначити, що творчі пошуки в галузі книжкового оформлення 1970-х–1980-х рр. були наслідком свідомої боротьби художників із зовнішнім прикрашательством і поверховим декоративізмом, позбавленим глибокого змісту. Українські майстри книжкової графіки Валентин Гордійчук і Анатолій Токарев своїми роботами спростовували тенденції певного занепаду візуальної мови цього періоду, після злету мистецтва книги 1950-х–1960-х рр. Київські художники Валентин Гордійчук і Анатолій Токарев ставали на шлях оновлення, органічно-цілісного вирішення всіх елементів оформлення книги. Зокрема, вони вважали за потрібне переосмислити «Енеїду» І. П. Котляревського,  активний колір і драматичну атмосферу, де пафос героїзму й усереднені образи починають поступатися думці про поему як глибший за змістом твір. Методологія дослідження полягає в застосуванні загальнонаукових методів (аналізу та синтезу, індукції та дедукції, єдності історичного і логічного) та мистецтвознавчих методів (компаративний, типологічний, описовий). Наукова новизна роботи полягає у дослідженні неофольклорних особливостей ілюстрування Валентина Гордійчука і Анатолія Токарева. Важливо підкреслити, що ілюстраторам України 1970-х–1980-х рр. було властиво зосереджуватися на духовно-культурних та пластичних засадах історичної малярської спадщини. Можна зазначити, що традиції доби бароко тісно переплітаються в цих ілюстраціях з національними народними мотивами. Тому надзвичайно плідним об’єктом дослідження є роботи майстрів книжкової графіки в новій художній трактовці літературних образів Івана Котляревського.
Development and validation of a framework for e-government readiness measurement
Authors:   , Joseph Seena
Published: May 2021

This study reports on the design of a framework for measuring e-government readiness. Particular attention is paid to providing a measurement framework that is feasible for municipalities and supports their efforts to utilize e-government for the benefit of the society and the economy. The evaluation of e-government readiness for municipalities can provide a useful barometer to measure the critical needs of citizens. In addition, it can be useful for improving the effectiveness of government services and could assist information communication technology industry to access information for implementing efficient infrastructures to support the delivery of e-services. The model of e-government readiness measurement as reported in this dissertation is based on heterogeneous factors of supporting e-services, individual citizens, technological infrastructure, government and supporting industry. The readiness measurement process utilized data obtained from a survey of 219 government employees from 4 municipalities in Eastern Cape Province of South Africa. The partial least square method was used to determine the relationship between the measured factors. The study results revealed the measurement factors to be significant determinants of municipality e-government readiness with an overall goodness of fit performance of 0.81 and predictive power of 0.68. In addition, a response based segmentation approach of finite mixture partial least squares is applied to uncover unobserved heterogeneity in government employees. The study findings show that the main difference characterising the two uncovered segments of population heterogeneity lies in the internet accessibility using computers. The impact of government readiness and technology readiness on predicting e-government readiness is stronger for the first segment than for the second segment. The segment specific analysis clearly shows that the impact of factors that influence the readiness of e-government can differ vastly, depending on the background of participants. The study findings generally provide a foundation for policymakers and technology practitioners who are interested in propagating e-government readiness awareness across the country. In addition, factors that determine the e-government readiness could provide new insights for future studies on e-municipality service improvement evaluations.

In several case of Tionghoa communities especially in terms of inheritance, a Tionghoa customs is continued to be used which are intended to regulate the differences rghts of boys and girls. In Tionghoa culture, boys are at high position because they are the successors of the clan (clan), contrariwise in Legislation of Civil Law (KUH Perdata) the position of girls and boys are equal. The gap of this differences fascinates the author to apply a research that will be published as a journal with the identification of the problem: How is the inheritance rights of Tionghoa girls toward the inheritance distribution in a legal perspective.This research uses a sociological juridical approach as means of a qualitative method. It is intended to provide a detailed explanation of the phenomenon which difficult to convey in form of quantitative method, to describe the differences between inheritance law that applies to Tionghoa communities and the inheritance legal system according to theThe results of this research confirm an essential difference between the customs and habits of Tionghoa communities and the inheritance legal system according to the Legislation of Civil Law (Burgelijk Wetboek), namely the Tionghoa Indonesian community assign the son as a truly successors of the inheritance of their parents. Therefore, the position of sons is more higher than girls because of the inheritance of the clan. In other hand, the girl does not obtain rights to inherit because the girl will follow her husbands when married.In Legislation of Civil Law (The position of girls and boys are equals, because the Legislation of Civil Law especially adheres to an individual inheritance system, bilateral and parental. In addition to these, the Legislation of Civil Law also know the terms of absolute part of the inheritance (legitime portie), whereas according to customary law; the position of Chinese is different, where the position of boys is higher than girls, this is because boys will take a responsibility to carry the name of their clan (clan) endlessly to the next descendants.The author recommend suggestions consider with with today’s developments and to accomplish the demands of a sense of justice, it is better for girls inherit without being discriminated. Meanwhile, the customs and culture are entrenched. However, a compromise is the middle way as resolution.

Abstract. As global change continues to progress, there is a growing interest in assessing any local levers that could be used to manage the social and ecological impacts of rising CO2 concentrations. While habitat conservation and restoration have been widely recognized for their role in carbon storage and sequestration at a global scale, the potential for managers to use vegetated habitats to mitigate CO2 concentrations at local scales in marine ecosystems facing the accelerating threat of ocean acidification (OA) has only recently garnered attention. Early studies have shown that submerged aquatic vegetation, such as seagrass beds, can locally draw down CO2 and raise seawater pH in the water column through photosynthesis, but empirical studies of local OA mitigation are still quite limited. Here, we leverage the extensive body of literature on seagrass community metabolism to highlight key considerations for local OA management through seagrass conservation or restoration. In particular, we synthesize the results from 62 studies reporting in situ rates of seagrass gross primary productivity, respiration, and/or net community productivity to highlight spatial and temporal variability in carbon fluxes. We illustrate that daytime net community production is positive overall, and similar across seasons and geographies. Full-day net community production rates, which illustrate the potential cumulative effect of seagrass beds on seawater biogeochemistry integrated over day and night, were also positive overall, but were higher in summer months in both tropical and temperate ecosystems. Although our analyses suggest seagrass meadows are generally autotrophic, the modeled effects on seawater pH are relatively small in magnitude. In addition, we illustrate that periods when full-day net community production is highest could be associated with lower nighttime pH and increased diurnal variability in seawater pCO2/pH. Finally, we highlight important areas for future research to inform the next steps for assessing the utility of this approach for management.

Abstract. Accelerated glacier mass loss is primarily attributed to greenhouse-induced warming, but land–climate interaction has increasingly been recognized as an important forcing at the regional-local scale. However, the related effects on the Himalayan glaciers are less explored but believed to be an important factor regulating spatial heterogeneity. This study aims to present a multi-decadal approximation on hydroclimate and glacier interaction over the western central Himalaya (WCH). Three highly coherent, multi-species, tree-ring δ18O site-chronologies from WCH were used to derive regional changes in atmospheric humidity (atmospheric moisture content: AMC) since the last four centuries. Coherency analyses between AMC and glacier mass balance (GMB: tree-ring δ13C-derived) indicate an abrupt phase-shift since the 1960s within a common record of 273 years. To ascertain the cause of phase-shift, annual AMC was disintegrated into seasonal-scale, utilizing δ18O record of deciduous species. Seasonal (winter: October–March; & summer-accumulation season: April–September) decomposition results reveal that winter-westerlies rather than summer precipitation from Indian summer monsoon (ISM) govern the ice-mass variability in WCH. Decadal coherency between summer-season AMC and GMB remained relatively stable since the mid-20th century, despite a decline in central Himalayan summer precipitation (tree-ring δ18O records). We hypothesize that excess water vapor brought to the atmosphere through increase in pre-monsoon precipitation and greening-mediated increase in evapotranspiration might have been recycled through the summer season to compensate for the ISM part of precipitation. However, isotope-enabled ecophysiological models and measurements would be able to strengthen this hypothesis. In addition, high-resolution radiative forcing and glacier valley-scale vegetation trend analyses point towards a probable influence of greening on GMB. Results indicate that attribution of ice-mass to large-scale dynamics is likely to be modulated by local vegetation changes. We contend that glacier-climate models fed with these feedback processes could reliably improve the projections.

This technique is based on the geometrized histograms method (GHM) for segmenting and describing color images (frames of video sequences) and on the facilities for global image analysis provided by this method. Basic elements of the technique that make it possible to solve image understanding problems almost without using the pixel arrays of images are introduced and discussed.A real-time parallel software implementation of the developed technique is briefly discussed. This technique is applied to solving problems of road scene analysis. The application to finding small contrast objects in images, like traffic signals and signal zones of vehicles is given. The developed technique is applied also to detecting other vehicles in the frame. The results of processing different frame of videos of road scenes are presented and discussed.
DEEP LEARNING FOR CODED TARGET DETECTION
Authors: Kniaz V. V. , Grodzitskiy L. , Knyaz V. A.
Published: May 2021

Abstract. Coded targets are physical optical markers that can be easily identified in an image. Their detection is a critical step in the process of camera calibration. A wide range of coded targets was developed to date. The targets differ in their decoding algorithms. The main limitation of the existing methods is low robustness to new backgrounds and illumination conditions. Modern deep learning recognition-based algorithms demonstrate exciting progress in object detection performance in low-light conditions or new environments. This paper is focused on the development of a new deep convolutional network for automatic detection and recognition of the coded targets and sub-pixel estimation of their centers.
NON-LINEAR MULTI-FRAME IMAGE DENOISING USING WEIGHTED NUCLEAR NORM MINIMIZATION
Authors: Nasonov A. V. , Volodina O. S. , Krylov A. S.
Published: May 2021

Abstract. We address the problem of constructing single low noise image from a sequence of multiple noisy images. We use the approach based on finding and averaging similar blocks in the image and extend it to multiple images. Unlike traditional multi-frame super-resolution algorithms, the block-matching approach does not require computationally expensive motion estimation for multi-frame image denoising. In this work, we use an algorithm based on weighted nuclear minimization for image denoising. The evaluation of the algorithm shows noticeable improvement of image quality when using multiple input images instead of single one. The improvement is the most noticeable in the areas with complex non-repeated structure.
SIMRES-TV: NOISE AND RESIDUAL SIMILARITY FOR PARAMETER ESTIMATION IN TOTAL VARIATION
Authors: Prasath V. B. S. , Hien N. N. , Thanh D. N. H. , Dvoenko S.
Published: May 2021

Abstract. Image restoration with regularization models is very popular in the image processing literature. Total variation (TV) is one of the important edge preserving regularization models used, however, to obtain optimal restoration results the regularization parameter needs to be set appropriately. We propose here a new parameter estimation approach for total variation based image restoration. By utilizing known noise levels we compute the regularization parameter by reducing the similarity between residual and noise variances. We use the split Bregman algorithm for the total variation along with this automatic parameter estimation step to obtain a very fast restoration scheme. Experimental results indicate the proposed parameter estimation obtained better denoised images and videos in terms of PSNR and SSIM measures and the computational overload is less compared with other approaches.
A NOVEL METHOD FOR PROTECTIVE FACE MASK DETECTION USING CONVOLUTIONAL NEURAL NETWORKS AND IMAGE HISTOGRAMS
Authors: Ryumina E. , Ryumin D. , Ivanko D. , Karpov A.
Published: May 2021

Abstract. This paper proposes a new hybrid method for automatic detection and recognition of the presence/absence of a protective mask on human's face. It combines visual features extracted using Convolutional Neural Network (CNN) with image histograms that convey information about pixel intensity. Several pre-trained models for building feature extraction systems using a CNN and several types of image histograms are considered in this paper. We test our approach on the Medical Mask Dataset and perform cross-corpus analysis on two other databases named Masked Faces (MAFA) and Real-World Masked Face Dataset (RMFD). We demonstrate that the proposed hybrid method increases the Unweighted Average Recalls (UARs) of recognition of the presence/absence of a protective mask on human's face in comparison with traditional CNNs on the MAFA and RMFD databases by 0.96% and 1.32%, respectively. The proposed method can be generalized and used for other tasks of biometry, computer vision, machine learning and automatic face recognition.

Published: May 2021

Abstract. Image matting often requires advanced image processing, especially in conditions, when small details such as hair are present in the image. In this article the hybrid method for human image matting based on convolutional neural network and principal curvatures is proposed. The U-Net based neural network is used to predict a rough foreground segmentation mask. Then the obtained foreground mask is refined by principal curvatures method to process the elongated hair-like structures. Test results show that the proposed method can improve the coarse human segmentation.

Published: May 2021

Abstract. The human desire to live in an urban area increases every day. However, citizens’ expectation of urban life is very different compared to the past. It is, thus, essential to satisfy their requirements and ensure their safety within their cities. As a result, there is a huge trend in the implementation of smart cities around the world. A smart city is a solution to improve the quality of life of the citizens, and governing the city in an efficient and systematic. Besides, significant advances have been raised in biometrics technologies, which have made many aspects of urban life easier, more efficient, and more secure. Accordingly, to be compliant with the demands of a smart city in the future, biometrics-based technologies will certainly play a significant role from now on. Thus, it is necessary to list the different biometrics methods that could be used in smart cities and to review the variety of applications for each method. In this article, we have listed the potential biometrics systems that can be employed in smart cities, such as facial recognition, age estimation, gender detection, facial expression detection and sentiment recognition, and gait recognition. We also have listed different applications imagined for each biometrics system such as their application in identification systems and security, smart healthcare, smart advertising, education, and high-risk lifestyle behaviours prevention. We believe that this work can help to better use of these methods, improve their technical quality, and also employing them in the advance and more effective ways.

Abstract. Studies of teeth represent a significant part of palaeoanthropological research. Over the past two decades these studies have significantly developed with implementation of high resolution imaging based on x-ray scanning techniques. Highly informative reconstructions based on image processing have provided an opportunity to study morphological layers and structures of teeth which are usually hidden under the outer layer of dental enamel. Thus micro-computed tomography of the studied teeth has been performed in order to obtain reconstructions of enamel and dentin surfaces. The material is represented by well-preserved teeth of an adolescent from Upper Palaeolithic archaeological site of Sunghir world-renowned archaeological site in Vladimir Oblast in the Russian Federation. The characteristic feature of the studied teeth is in their unusual, presumably archaic, morphology, which has been previously studied and described through measurements by application of automated digital odontometry method; however the mentioned study referred to the enamel surface. And in the current study these algorithms are applied to measure the surface of dentin. As this is the first successful attempt of measuring dentin surface morphology, the process has to be improved for complete automation. Nevertheless even currently applied approaches allow to compare enamel and dentin morphology through measurements.
Randomized Controlled Trials in Medical AI A Methodological Critique
Authors: Genin Konstantin , Grote Thomas
Published: May 2021

Various publications claim that medical AI systems perform as well, or better, than clinical experts.However, there have been very few controlled trials and the quality of existing studies has been calledinto question. There is growing concern that existing studies overestimate the clinical benefits of AIsystems. This has led to calls for more, and higher-quality, randomized controlled trials of medicalAI systems. While this a welcome development, AI RCTs raise novel methodological challenges thathave seen little discussion. We discuss some of the challenges arising in the context of AI RCTs andmake some suggestions for how to meet them.

Published: May 2021

Currently, agricultural science and practice has a large amount of experimental data that must be taken into account when developing new technological processes and working bodies. Therefore, there is a need to design technical processes in order to identify their effectiveness. Based on the principle of decomposition of design processes, a model of the technology design process is developed. The main feature of this model is the consistent improvement of the initial version to the required degree of perfection.
INCREASING THE EFFICIENCY OF COMBINED PRODUCTION HEAT AND ELECTRICITY
Authors: Maximov Maxim Olegovich
Published: May 2021

The main directions of increasing the efficiency of combined production of electric and heat energy are considered, associated with the improvement of power generating equipment, regime and circuit changes in heat supply systems while ensuring heat load. For many years, centralized heat supply based on combined heat and power generation has been successfully developing in Russia, which is a very attractive energy and nature saving technology. Its use makes it possible to save about 20 million tons of fuel annually, which is about 14% of the total volume of fuel consumed in Russia for the needs of heat supply. More than 50% of electricity is generated at CHPPs in Russia, and the efficiency of fuel use at them reaches about 70–75%. Such areas include the use of steam and gas technologies (CCGT units and gas turbine superstructures of equipment of operating CHPPs) and GTU-CHPPs, increasing the initial steam parameters at CHPPs, superstructure of hot water boilers with gas turbine units, improvement and modernization of existing turbine equipment and CHPP schemes, as well as rejection of peak boilers in favor of peak boilers at CHPPs, transition to a lower temperature schedule and a change in the structure of heat supply systems. The main advantages of these areas and the problems associated with their implementation are presented. The conditions of possible and expedient application of some directions are considered. It is shown that, in many respects, the choice of certain technical solutions, despite the energy efficiency, is determined by the conditions of the regional heat and electric energy markets.

Twitter, Facebook & Co – Plus média ou social?
Authors: Andrea Frattolillo Davide Cerutti und
Published: May 2021

Lorsque les art. 17 Cst. et 28 CP sont entrés en vigueur à la fin du siècle passé, les réseaux/médias sociaux, du moins tels que nous les connaissons, n’existaient pas encore. Depuis leur apparition, plusieurs aspects juridiques ont été remis en cause, dont la définition de ce qu’il faut comprendre par « média ». Différents tribunaux se sont prononcés sur la question à l’égard de Twitter et Facebook, en arrivant à des réponses diverses et variées. L’interprétation de ces dispositions et l’analyse de la doctrine et jurisprudence en la matière montrent cependant que ces plateformes ne peuvent être considérées comme des médias au sens juridique du terme.
Print Capitalism
Authors: Cheema Iqra Shagufta
Published: May 2021

Benedict Anderson connects the rise of print capitalism to the rise of nationalism in Europe as well as in the colonies. Print capitalism and nationalism shared a similar relationship in the Indian subcontinent too that remained a British colony for almost 200 years, from 1757 to 1947. Employing Deputy Nazir Ahmad’s novel, Mir’āt al-‘Urūs (1869), I argue that the introduction of print capitalism proved crucial to the rise of Muslim national consciousness and for Muslim women’s education to redefine their sociopolitical role in the new Muslim imagined community under British colonization. Print capitalism, via the possibility of mass-produced books like Mir’āt al-‘Urūs, transformed the Muslim national imagination by making Indian Muslims a community in anonymity. I offer this new reading of Mir’āt al-‘Urūs to trace the interaction of print capitalism, Muslim national consciousness, and new roles for Muslim women in colonial India.
