Authors: Dianova Elena Vasil'evna
Published: October 2020

The article highlights different aspects of interagency conflict between political and educational bodies, Agitprop (Department for Agitation and Propaganda of the Central Committee of the All-Russian Communist Party (Bolsheviks)) and other organizations involved into cultural and educational activity (People’s Commissariat for Education, Komsomol, trade unions, Political Department of the Revolutionary Military Council). Scientific originality of the study is conditioned by the fact that conflict is considered as representation of social crisis that occurred during transition to New Economic Policy and also by the fact that the author reveals “liquidationist moods” and “syndicalist tendencies” among representatives of agencies and institutions. The research findings are as follows: the author identifies causes of interagency conflict, describes its features and shows ways to settle disagreements between the parties.
Cultural Revolution Influence on the Chinese Orchestras
Authors: Zhao Xiaolin
Published: October 2020

The paper aims to reveal peculiarities of the Chinese orchestral performance development during and after the Cultural Revolution. The author examines classical musical compositions of the analysed period, identifies their distinctive features and considers the state influence on the Chinese musical ensembles. Scientific originality of the study lies in the fact that the researcher provides a comprehensive analysis of orchestral activity during the Cultural Revolution; this problem remains poorly investigated in the modern Chinese musicology. Contrary to the established opinion, the mentioned period is not considered as a dead-end branch of China development, which allows offering a new interpretation of orchestral creativity. The research findings are as follows: the author proves that the Cultural Revolution is not a stagnation period in orchestral performance development but an epoch of innovations.

Published: October 2020

The preservation of the stability of world peace became one of the wishes of the entire international community. But these expectations seemed to be a sense of concern in the event of a war between countries using nuclear weapons. International law governs the nuclear weapons of international treaties, one of which is the Treaty on Non-Proliferation of Nuclear Weapons in 1968. In addition to providing a guarantee of a sense of security was formed No First Use Policy to ensure the country owners of nuclear weapons are not the first party to use nuclear weapons in the event of a conflict with other countries. The purpose of this research is to learn about the implementation of No First Use Policy on the use of nuclear weapons by the countries that have them and the international security of the world. The method used in the study is normative juridical is supported by data obtained by library research. Regarding the implementation of the No First Use Policy each country with nuclear weapons has different attitudes about it. Whereas No First Use Policy has had a positive impact on the arrangement of the use of nuclear weapons of the world for security and order.

Authors: Merliana Merliana , Dihansih Elis , Wahyuni Dewi
Published: October 2020

Daging itik merupakan salah satu bahan pangan yang masih kurang diminati oleh masyarakat. Beberapa faktor yang menyebabkan kurangnya minat masyarakat untuk mengkonsumsi daging itik adalah karena adanya aroma bau amis. Asam gelugur (Garcinia antroviridis) mengandung asam-asam organik seperti asam tartarik, asam sitrat, asam malat dan asam hidroksisitrat. Asam hidroksisitrat (HCA) merupakan asam organik utama yang berkhasiat sebagai antilipidemik dan antiobesitas. Penelitian dilakukan selama 40 hari yaitu bulan Mei - Juni 2019 bertempat di kandang unggas Program Studi Peternakan Fakultas Pertanian Universitas Djuanda Bogor. Ransum yang digunakan adalah ransum nonkonvensional terfermentasi. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan 5 ulangan. Setiap perlakuan terdiri dari R0 = 0% tepung daun asam gelugur, R1 = 2% tepung daun asam gelugur, R2 = 4% tepung daun asam gelugur, R3 = 6% tepung daun asam gelugur. Data dianalisis menggunakan Kruskal Wallis. Peubah yang diamati yaitu uji hedonik dan uji mutu hedonik (aroma, keempukkan, warna, rasa dan juiceness). Hasil penelitian menunjukan bahwa pemberian tepung daun asam gelugur berbeda nyata (P<0,05) terhadap warna daging itik pada uji hedonik dan pada uji mutu hedonik berbeda nyata (P<0,05) terhadap warna dan rasa daging itik. Pemberian tepung daun asam gelugur (Garcinia antroviridis) sebesar 6% dalam ransum nonkonvensional terfermentasi meningkatkan kesukaan panelis terhadap warna daging dan meningkatkan kecerahan warna daging akan tetapi tidak merubah rasa, aroma, keempukan dan juiceness daging itik

A Review of questionnaires quantifying bilingual experience in children: Do we document the same constructs?
Authors: Kašćelan Draško , Prevost Philippe , Serratrice Ludovica , Tuller Laurie , Unsworth Sharon , De Cat Cecile
Published: October 2020

Questionnaires documenting children’s bilingual experience have been used frequently in research on language and cognitive development. However, there has been little investigation of the comparability between these tools. In this review, we (i) provide a list of available questionnaires used to quantify bilingual experience in children; (ii) identify the components of bilingual experience documented across questionnaires; and (iii) discuss the comparability of the measures used to operationalise these components. In doing so, we review 48 questionnaires and identify 32 overarching constructs, manifested as 194 components, and we calculate the frequency with which they are documented. Finally, by focusing on a subset of overarching constructs (language exposure and use, activities, and current language skills), we observe high variability in their operalisations across the tools. These findings highlight the need for greater transparency in how we document bilingualism and for more comparable measures.

Perkembangan Pendidikan Islam pada Periode Khulafāur Rāsyidīn dan Implikasinya terhadap Pengembangan Pendidikan Islam di Indonesia
Authors: Zebua Rony Sandra Yofa , Ihsan Miftahul , Nurjanah Neneng
Published: October 2020

Religious education for Muslim is Islamic Education originating from Al-Qur’an dan As Sunnah. This study elucidates the dynamic of the change and development of Islamic education in the era after the death of the prophet Muhammad shallallāhu 'alaihi wa sallam, especially in the period of Khulafāur Rāsyidīn. It was revealed how the education system had been implemented in each caliphate and the situation having influenced the educational system. The finding showed that the pattern of the education in the era of caliph Abu Bakar radhīyallāhu ‘anhu was generally still same as the system applied in the era of the prophet of Muhammad shallallāhu 'alaihi wa sallam. The massive development occurred in the period of caliph Umar bin Khatab radhīyallāhu ‘anhu which was continued with the caliph Utsman bin Affan radhīyallāhu ‘anhu. Nevertheless, there were some fundamental changes, especially in the regulation as well as the education method. Original Source: https://ojs.pps-ibrahimy.ac.id/index.php/jpii/article/view/228
Validation of Morality as Cooperation Questionnaire in Turkey, and its Relation to Prosociality, Ideology, and Resource Scarcity
Authors: Yilmaz Onurcan , Harma Mehmet , Doğruyol Burak
Published: October 2020

The theory of morality as cooperation (MAC) argues that there are seven distinct and evolved universal moral foundations. Curry, Chesters, and van Lissa (2018) developed a scale to test this theoretical approach and showed that the Relevance subscale of the MAC questionnaire (MAC- Q) fits data well, unlike the Judgment and full form. However, an independent test of the validity of this questionnaire has not been hitherto conducted, and its relation with ideology is unknown. In the first study, we attempted to validate the Turkish form of MAC-Q and then examined the relationship with prosociality and political ideology. The results showed that the fit indices of MAC-Q Relevance are above the standard criteria, unlike the Judgment and full form (n=445), and significant relationships with prosociality and political ideology provided additional evidence for the validity. We used the MAC-Q Relevance in Study 2 (n=576, Turkey) and Study 3 (n=921, US), and investigated whether manipulating resource scarcity influences the endorsement of MAC. Although there was no effect of the manipulation, correlational findings provided some support for the predictive validity of MAC-Q. Overall, MAC-Q Relevance performs well in representing the lay notions of morality in both Turkey and the US, unlike full form.
Coping with Health Threats: The costs and benefits of managing emotions.
Authors: Smith Angela Moriah , Willroth Emily C , Gatchpazian Arasteh , shallcross amanda , Feinberg Matthew , Ford Brett Quaid
Published: October 2020

How people respond to health threats can influence their own health and, when facing communal risks, even their community's health. We propose that people commonly respond to health threats by managing their emotions with cognitive strategies like reappraisal, which can reduce fear and protect mental health. However, because fear can also motivate health behaviors, reducing fear may also jeopardize health behaviors. In two diverse U.S. samples (N=1,241) tracked across three months, sequential and cross-lag panel mediation models indicated that reappraisal predicted lower fear about an ongoing health threat (COVID-19), and in turn, better mental health, but fewer recommended physical health behaviors. This trade-off was not inevitable, however: using reappraisal to increase socially-oriented positive emotions predicted better mental health without jeopardizing physical health behaviors. Examining the costs and benefits of how people cope with health threats is essential for promoting better health outcomes for individuals and communities.
Prosperity and prestige: Archaeological realities of unfree laborers under Inka imperialism
Authors: Hu Di , Quave Kylie
Published: October 2020

Inka imperial policies reorganized the social and labor landscapes of their subjects on a grand scale and unprecedented degree in the Americas. The two most numerous categories of resettled laborers created by these imperial policies were the mitmaqkuna and yanakuna, who together represented at least a third of the total subject population. The Inkas resettled them, often far from their homelands. They were responsible for the daily provisioning of Inka settlements and keeping the peace among conquered populations. Despite their central role in Inka state consolidation and economy, we know little about these populations outside of ethnohistorical interpretations of their privileged status relative to normal tribute-paying communities. Because ethnohistoric documents were written with Inka and Spanish state interests in mind, archaeological evidence is crucial to evaluate their lived experiences. We compare the ethnohistoric and archaeological evidence of the lives of the mitmaqkuna and yanakuna in two regions: the mitmaqkuna site of Yanawilka in the Vilcas Huamán province and the yanakuna site of Cheqoq in the rural Inka heartland of Cuzco. Archaeological comparisons yield evidence contradicting the long-held assumption that prestige is synonymous with autonomy, power, or even wealth in imperial contexts.
Projeto, implementação e modelagem compacta de transistores MOSFET na configuração pseudorresistor para circuitos aplificadores de biosinais
Authors:   , Pereira C. F.
Published: October 2020

This work shows the SPICE PWL (PieceWise Linear) macromodel development aiming a pseudo-resistor simulation. The lack of a SPICE simulation model that correctly describes the pseudo-resistor behavior is the main inspiration of this designing. A bio-amplifier for the QRS complex detection was made as a case study for the validation of the developed PWL macromodel. The temperature dependency of the pseudo-resistor equivalent resistance also was characterized and included in the macromodel. The circuits lay-out were developed using the Global Foundries 8HP 0.13 µm technology, resulting in a fabricated integrated circuit. To draw the bio-amplifier gain response and its transitory recovery time behaviors, some experimental analyses was made. Experimental analysis with an emulated ECG signal also was made to characterize the bio-amplifier as a QRS detector, and the obtained results were very well. A few bio-amplifier simulation results that include the macromodel were presented in order to evaluate this device. Furthermore, bioamplifier characterization were also carried out as a function of temperature variation. All of the analysis early mentioned were performed considering the temperature variation from room temperature up to 60 ºC. Comparing the simulated response and the experimental data with same input conditions, can be seen that de proposed macromodel provides a suitable pseudo-resistor behavior

Сравнительный анатомо-морфологический анализ вегетативных органов Iris sogdiana из различных условий произрастания представляет интерес, поскольку позволяет выявить особенности и адаптационные возможности вида. Микроскопические исследования вегетативных органов I. sogdiana из природных популяций юго-восточного Казахстана проведены впервые. Показана положительная корреляция между местообитанием и морфометрическими параметрами вида. Выявлены особенности строения вегетативных органов и установлено, что развитие покровной, основной и проводящих тканей у I. sogdiana связано с градиентом увлажнения. Для листовой пластинки характерны многочисленные устьица, слегка погруженные вглубь листа; многочисленные межклетники; воздухоносныеполости в мезофилле листа; проводящие пучки, окруженные клетками склеренхимы. У стебля наблюдается определенная степень ребристости, утолщенная поверхность наружных клеток эпидермиса, выраженный слой склеренхимы перицикла. Корень имеет одно-двухслойную эктодерму, развитые утолщения радиальных оболочек клеток эндодермы, разное количество сосудов в зависимости от мест произрастания. Результаты исследования свидетельствуют о том, что растения 1- и 2-й популяций характеризуются более ксерофитными чертами организации, для растений 3-й популяции присущи мезофитные черты. Исследуемый вид отличается усредненными морфометрическими показателями строения и включает мезоксерофитную организацию анатомической структуры. Морфологическое строение I. sogdiana позволяет заключить, что в течение короткого периода вегетации для развития растения необходимо достаточное количество влаги.

Biological oxidation of ferrous sulfate by Acidithiobacillus ferrooxidansand Acidithiobacillus ferrivoransis an important process in the bioleaching of minerals and the treatment of acid mine drainage. The rate at which biooxidation reactions take place is directly related to the microorganisms’growth temperature. Decreasing the temperature of reaction causes both a decrease on the chemical reactions rates and a decrease on bacterial growth. In this study, the effects of pH and temperatures on oxidation of ferrous sulfate by a native At. ferrooxidans and At. ferrivorans strains were investigated. The biooxidation tests conducted in shake flasks at 28 °C and 8 °C and at initial pH 1.6 for 5 days. During the experiment, the mesophilic iron oxidizers were capable of growing on ferrous iron at concentrations of 4.5 g/L at low and optimum temperature. However, the rate of mesophilic biooxidation of ferrous ironwas higher than that observed in the psychrophilic biooxidation. In conclusion, during the experiment the At. ferrivorans strain 535 showed high activity in oxidizing at low temperature than other strains. It means even at very low temperatures, microorganisms play an important role in the oxidation and leaching of sulphide ores.

The article presents the study results made on the Adonis wolgensiscoenopopulation in Northern Kazakhstan (2018–2019). The materials have been gathered in the course of field research taking into account the literary data. The age structure of the coenopopulations is provided on the basis of detailed route studies. There have been studied eight coenopopulations located in Akmola, Pavlodar, and Kostanay regions. A. wolgensisis a short-stem herbaceous polycarpic of Northern Kazakhstan. A. wolgensiscoenopopulations are found in three main habitats: steppe, meadow-steppe, and forest communities. The study of A. wolgensis coenopopulations in the latitudinal direction from Ekibastuz in the east to the Kostanay region in the west has revealed a high recovery index in steppe ecotopes. In other coenopopulations it is less than one. It is especially low in forest habitats. Most coenopopulations have a normal character according to the spectrum of age conditions, and they are maturing. This fact proves no negative impact of environmental and anthropogenic factors on the structure of coenopopulations and ensures their recovery and preservation.

Структурные изменения хромосом, проявляющиеся вследствие химического мутагенеза, как показывают исследования, зачастую вызваны высокими концентрациями тяжелых металлов в воздухе и пылипромышленных городов. Целью статьи явилось изучение роли цинка в образовании хромосомныхаберраций. Исследована частота встречаемости хромосомных аберраций и хромосомных аномалийу лиц, проживающих в условиях повышенной химической нагрузки. Также изучен уровень хромосомных аберраций у лиц, проживающих на территории экологического бедствия. Выделены типы и характер цитогенетических нарушений. Проведен расчет индивидуальных дозовых нагрузок поступления химических веществ в организм из объектов окружающей среды. Методом моделирования пред-ставлена роль цинка в формировании хромосомных аберраций. Выявлена достоверно значимая обратная корреляционная связь между уровнем хромосомных аберраций и содержанием цинка в атмосферном воздухе (коэффициент парной корреляции Пирсона составил 0,39). Установлено, что при снижении концентрации цинка в атмосферном воздухе статистически значимо повышается уровень хромосомных аберраций. Дана характеристика коферментной активности цинка в функционировании ферментов системы репарации и антиоксидантной защиты. Выявлено, что хромосомные аберрации являются рефлекторами при условиях экспозиции экологических факторов экзогенного и эндогенного происхождения, вследствие чего происходят изменения в функционировании всей клетки.

Published: October 2020

The study of the biology and morphology of seed germination of medicinal plants is an important aspect of species introduction. This article investigated the features of the biology of germination and seed germination of a perspective medicinal plant Scabiosa ochroleuca depending on various factors. It is determined that seeds of some geographical origin differ in size and weight, the morphology of seedlings, which is explained by the difference in soil and climatic conditions. The best values of germination (90.5 %) and germination energy (80.3 %) of seeds were recorded in large samples collected in the Buiratau mountains, the minimum — in small seeds collected in the Karkaraly mountains (germination 14.0 %, germination energy 8.5 %). The maximum morphological parameters of seedlings, such as the length of the root, the length of the hypocotyl, the length and width of the cotyledon leaf, are revealed in seeds from the Karkaraly mountains; the minimum — from the vicinity of the village Karagaily. This aspect indicates the need to select seeds for in-troduction from certain habitats and to separate them before sowing. Stages of germination of seed material of this medicinal plant are defined, including the following: swelling of seeds, tilting, appearance of root, ap-pearance and bending of hypocotyl, removal of cotyledon leaves, and deployment of cotyledon leaves. Dynamics of seeds germination during storage (from freshly harvested seeds up to 3 years) was determined, positive influence of stratification during 3 months was revealed to increase seed germination and germination energy. According to the results of the studies, it was determined that the seeds of Scabiosa ochroleucaare characterized by the lack of drainage during wetting, the terrestrial type of germination, shallow physiological rest, by the type of germination are assigned to the group of seeds with accelerated germination.

В статье впервые представлены результаты определения оводненности побегов и листьев и жаростойкости 10-ти интродуцированных сортов яблони в связи с их сезонным развитием и продуктивностью в экстремальных природных условиях Мангистау. Выявлено, что оводненность побегов и листьев сортов яблони менялась в течение вегетационного периода, возрастая и снижаясь в связи с изменением погодных условий. Наиболее высокая оводненность листьев наблюдалась преимущественно в мае, к концу вегетации оводненность листьев достигала минимальных значений. При этом наблюдалось периодическое снижение и повышение оводненности (пульсация) в течение вегетационного периода. Резкое падение оводненности листьев было зафиксировано у большинства сортов в середине августа, в период завершения созревания плодов и одревеснения побегов. Жаростойкость тоже менялась в течение вегетационного периода, снижаясь с мая по сентябрь. Высокая жаростойкость отмечена у сортов «Столовка» и «Ренет Бурхардта», которые характеризуются высокой продуктивностью.

Introduction: Owners of multimedia products face an important problem of protecting their digital data. An effective way to solve it is digital watermarking of video sequences. The challenge is the need to improve the digital watermark tolerance for transcoding when the data are transmitted via unprotected channels. Purpose: Development of method for embedding data into a video sequence which would have a higher tolerance for transcoding. Methods: We propose a novel method for embedding and extracting textual digital watermarks based on the bar coding and Arnold transform. Results: Blind marking schemes have been developed for digital video sequences in chromatic components, based on the discrete wavelet transform and discrete cosine transform. An experimental study has been conducted to check the stability of the proposed method using encoders x264 (AVC/H.264) and x265 (HEVC/H.265). The estimation of transcoding impact has shown that the frequency method based on wavelet decomposition has a high degree of stability. It was discovered during the experiments that for the cases of video transcoding by single-pass compression with a Constant Rate Factor not exceeding 26, the embedded textual information is fully restorable. Practical relevance: The developed method allows you to reliably embed or extract textual data from video sequences compressed using highly efficient coding methods during their transmission viaunprotected channels, providing copyright protection for multimedia product owners.

Deep Learning (DL) plays an important role in machine learning and artificial intelligence. DL is widely applied in many fields with high dimensional data, including natural language processing, image recognition. High dimensional data can lead to problems in machine learning such as overfitting, degradation of accuracy. To address these issues, some methods, such as Principal Components Analysis (PCA), principal component regression (PCR), Multi-class Linear Discriminant Analysis (MLDA), were proposed to reduce dimensions of the data and computational complexity simultaneously. The drawback of these methods is that they only work well on data distributed on the plane. In the case of the data distributed on the hyper-sphere, such as objects moving in space, the processing results are not so good as expected. In this paper, we propose the use of Conformal Geometric Algebra (CGA) to extract features and simultaneously reduce the dimensionality of a dataset for human activity recognition using Recurrent Neural Network (RNN). First, human activity data in a 3-dimensional coordinate system is pre-processed and normalized by calculating deviations from the mean coordinate. Next, the data is transformed to vectors in CGA space and its dimensions are reduced to return the feature vectors. Finally, we use the RNN model to train feature vectors. Empirical results performed on the CMU eight actions dataset show that the CGA combined with RNN gave the best test results of 92.5%.

Published: October 2020

Introduction: Due to its advantages, such as high flexibility and the ability to move heavy pieces with high torques and forces, the robotic arm, also named manipulator robot, is the most used industrial robot. Purpose: We improve the controlling quality of a manipulator robot with seven degrees of freedom in the V-REP program's environment using the reinforcement learning method based on deep neural networks. Methods: Estimate the action signal's policy by building a numerical algorithm using deep neural networks. The action-network sends the action's signal to the robotic manipulator, and the critic-network performs a numerical function approximation to calculate the value function (Q-value). Results: We create a model of the robot and the environment using the reinforcement-learning library in MATLAB and connecting the output signals (the action's signal) to a simulated robot in V-REP program. Train the robot to reach an object in its workspace after interacting with the environment and calculating the reward of such interaction. The model of the observations was done using three vision sensors. Based on the proposed deep learning method, a model of an agent representing the robotic manipulator was built using four layers neural network for the actor with four layers neural network for the critic. The agent's model representing the robotic manipulator was trained for several hours until the robot started to reach the object in its workspace in an acceptable way. The main advantage over supervised learning control is allowing our robot to perform actions and train at the same moment, giving the robot the ability to reach an object in its workspace in a continuous space action. Practical relevance: The results obtained are used to control the behavior of the movement of the manipulator without the need to construct kinematic models, which reduce the mathematical complexity of the calculation and provide a universal solution.
Storage scaling management model

Published: October 2020

Introduction: The implementation of data storage process requires timely scaling of the infrastructure to accommodate the data received for storage. Given the rapid accumulation of data, new models of storage capacity management are needed, which should take into account the hierarchical structure of the data storage, various requirements for file storage and restrictions on the storage media size. Purpose: To propose a model for timely scaling of the storage infrastructure based on predictive estimates of the moment when the data storage media is fully filled. Results: A model of storage capacity management is presented, based on the analysis of storage system state patterns. A pattern is a matrix each cell of which reflects the filling state of the storage medium at an appropriate level in the hierarchical structure of the storage system. A matrix cell is characterized by the real, limit, and maximum values of its carrier capacity. To solve the scaling problem for a data storage system means to predict the moments when the limit capacity and maximum capacity of the data carrier are reached. The difference between the predictive estimatesis the time which the administrator has to connect extra media. It is proposed to calculate the values of the predictive estimates programmatically, using machine learning methods. It is shown that when making a short-term prediction, machine learning methods have lower accuracy than ARIMA, an integrated model of autoregression and moving average. However, when making a long-term forecast, machine learning methods provide results commensurate with those from ARIMA. Practical relevance: The proposed model is necessary for timely allocation of storage capacity for incoming data. The implementation of this model at the storage input allows you to automate the process of connecting media, which helps prevent the loss of data entering the system.
Method of automatic search for odor-induced patterns in bioelectric activity of a rat olfactory bulb

Published: October 2020

Introduction: The olfactory system in chronic animal experiments is studied according to the records of bioelectric activity recorded with microelectrode arrays located on the dorsal surface of the olfactory bulb. It is believed that the response of the olfactory bulb bioelectric activity to the odorant presentation is associated with fluctuations synchronized by respiration and belonging to the range of so-called gamma rhythms. Purpose: To develop a method of automatic search for time boundaries of odor-induced gamma rhythm patterns in the bioelectric activity of an olfactory bulb. Results: The complexity of automatic search for odor-induced patterns are due to masking them by spontaneous oscillations of gamma rhythms unrelated to the olfactory system activity. Besides, the modal frequency of the patterns is a priori unknown and changes dynamically during an experiment on an anesthetized animal. The Hausdorff distance is used as a cost function of the search. In order to increase its sensitivity, an adaptive band-pass filter was synthesized based on a multichannel singular spectrum analysis. Its passband in the analyzed time sample corresponds best to the spectrum of the required patterns. The results of experiments on rats are presented. The use of band-pass filters based on the Fourier transform with parameters unchanged during the experiment due to the non-stationary  nature of the frequency characteristics of the desired patterns does not ensure their effective search. In particular, when using the Butterworth band-pass filter in the search algorithm, significant errors were observed in determining the time boundaries of the epochs of patterns, and omissions of patterns. But the use of a synthesized adaptive band-pass filter provided reliable automatic search for patterns and determination of their time boundaries with a high accuracy. Algorithm failures in this case were observed only in rat motion artifacts. Practical relevance: The developed method extends the existing tools used to study the olfactory system of a living organism.
