Confronting Pandemics: Human and Non-Human Agents in the Discourse of the Moscow Authorities on COVID-19
Authors: Bagina Yana , Zaporozhets Oksana , Govorova Anastasia 
Published: December 2022

The article is devoted to the discourse of the Moscow city authorities regarding COVID-19. We believe that this discourse is closely connected with the implemented city policies, articulating and legitimising them. The empirical base of the study is news from the official website of the Mayor of Moscow and entries from the blog of the Mayor of Moscow Sergey Sobyanin. The article focuses on discursively created agents of urban life, the attitude of city authorities towards them and the relationship between them during the COVID-19 pandemic.
There are many human and non-human agents in the coronavirus discourse: government officials, townspeople, agents associated with the treatment of coronavirus (medical workers and technologies), and agents associated with the life of the city during the pandemic (infrastructure, organisations and companies, employers, education system). All of them are built around a key agent - the virus itself. Citizens as agents in power discourse are represented by a variety of categories that form two large overlapping groups. The first group is associated with the position of people regarding the disease: people with suspected coronavirus, who fell ill with varying degrees of severity of the disease, recovered, died; donors, vaccine study participants, vaccinated. Over the analysed time period, the discourse related to morbidity undergoes at least two turning points: the transition from a small number of cases to statistics disaggregated in terms of age, and from disaggregated statistics to the total number of cases with an emphasis on the number of severe cases of the disease. The second group of categories of citizens includes belonging to certain social groups, for example, an age cohort, socially vulnerable groups, workers (in general and in certain industries), schoolchildren and students, service users, public transport passengers.
Citizens are viewed by city officials as important agents involved in the fight against the pandemic. Their agency is discursively produced as a result of the interaction between themselves and the city authorities. Citizens who follow the authority rules gain agency, while those who do not follow them are deprived of it due to rare mention or omission.

In this article, an analytical review of the literature on methods for measuring the stabilization error of stabilization systems (SS) is carried out. The relevance of further research and development in the field of ways to improve the accuracy of measurements of the stabilization error of the SS is substantiated.
The modern method for determining the median error of the SS has distinctive features and has a number of advantages: it requires much less time and the use of manual labor; performed in digital form of information processing in numerical and graphical form; does not require the need to install a movie camera (it was replaced by an optoelectronic module, information from which is fed to the input of a video monitor, to which it is connected via the Pinnacle Movie Box Plus USB matching device, through which the video image is transmitted for recording to a laptop). After performing the research, information according to a specially developed program is automatically processed on a computer, which, based on the results of calculations, gives a more accurate (compared to the new method) value of the median stabilization error along the horizontal and vertical guidance channels.
The model of construction of the line of domestic SS corresponds to the principle of "dependent stabilization" rigid connection of vertical and horizontal channels of the stabilizer with the device of supervision over objects.

Published: December 2022

Precision farming is a modern direction of agricultural development, which opens new opportunities to increase the productivity of each land by taking into account its specific features. Its implementation requires an assessment of the spatial heterogeneity of soils and agricultural vegetation. This ensures the timely application of adequate agricultural measures in those places that need it.
In this work, ways of solving the problems of precision farming are analyzed. The expediency of using a quadcopter with a technical vision system to obtain high-resolution images of the studied land plot is shown.
Specialized systems of technical vision for the tasks of precision agriculture are currently not mass-produced. Therefore, a block diagram of the quadcopter's technical vision system was developed, which made it possible to determine the necessary technical characteristics and select the appropriate industrial equipment.
Necessary software and algorithms were developed for the technical vision system. The proposed algorithm is based on the use of high-quality images from the technical vision system of the quadcopter, low-resolution satellite images and the results of agrochemical analyzes. When processing data, individual images taken with a quadcopter camera are combined into a single orthofotoplan. Then NDVI indicators from satellite images and results of agrochemical analyzes are added to it. The identified zones of plant fertility make it possible to build a differentiated fertilizer application map and a map of the agro-operations task plan for precision farming equipment.
To verify the results, studies were conducted on a test site with an area of 57.4 hectares, which was located in the Chaplin district of Kherson region. With the help of the selected equipment and the developed algorithms, images of the area were obtained, an orthofotoplan with plant germination zones was formed, and a map of fertilizer application for precision farming equipment was developed. Field studies fully confirmed the correctness of the calculations and the performance of the proposed algorithms.

Published: December 2022

Problems. Rapid technical progress has led to a reduction in the useful life of consumer electronics. The introduction of green, flexible, biodegradable electronic devices will prevent an environmental catastrophe. Recently, the use of organic materials instead of inorganic analogues has become increasingly popular, which makes it possible to move from rigid solid-state sensors for multiple use that require disposal to flexible, disposable sensors that are suitable for human wear on the body or clothing and for spontaneous decomposition in nature after using. One of such promising organic materials is nanocellulose.
The aim of the study. Studying the possibility of nanocellulose application for the manufacture of flexible, wearable, disposable sensors of various types of physical and chemical quantities.
Methodology of implementation. In the article the analysis, classification and comparision of various technologies and features of synthesis, as well as the main characteristics of flexible sensors made on the basis of nanocellulose were fulfilled. Also the main parameters of flexible sensors based on nanocellulose were being compared with corresponding analogs of sensors based on artificial polymers.
Research results. The paper established the physical and technological features of using nanocellulose for the manufacture of sensors of various types of physical and chemical quantities in order to improve their performance. It has been established that nanocellulose can be used both as a substrate and as a sensitive element of a sensor. It has also been shown that nanocellulose is suitable for use in sensors based on both electrical physical phenomena and optical effects.
Conclusions. Nanocellulose is a promising biodegradable material on the basis of which flexible, disposable, wearable sensors can be created. The manufacturing technology of such sensors should contain only low-temperature and dry processing processes. For effective use in certain types of sensors, it is advisable to manufacture nanocellulose with a modified surface or in the form of composites with other nanomaterials. Based on the obtained results, it is possible to improve existing and develop new methods of creating flexible wearable disposable sensors that do not require disposal.

Background. Studies have proven the effect of several agents, including natural products, to induce, prevent and treat genotoxicity through experimental models and clinical trials. In this study, the genotoxic preventive potential of Annona muricata ethanol extract on N-Ethyl-N-Nitrosourea (ENU)-induced pro-leukaemia in mice models using micronuclei formation in bone marrow was assessed.
Materials and methods. Forty-eight mice weighing 18-24g were randomly divided into six groups of eight mice. The mice were intravenously administered 20mg/kg of NEU 48 hourly 3 times, 80mg/kg of NEU 48 hourly 3 times. The negative control was fed with feed and water only. We introduced 0.2ml (0.1g/ml) ethanolic extract of Annona muricata for 3 weeks prior to NEU low dosage administration, 0.2ml (0.1g/ml) ethanolic extract of Annona muricata for 3 weeks prior to ENU high dosage and Annona muricata (ethanolic extract) administration, and gave commercial diet to the adverse/ toxicity group. The bone marrow was harvested, smeared and stained using MayGrumwald. The procedure enabled the determination of micronucleus polychromatic erythrocytes (MNPCEs) microscopically.
Results. Groups exposed to various dosages of the ENU yielded significantly increased MNPCEs, with group B producing higher MNPCEs. The groups treated with the extract displayed a significant reduction in the MNPCEs despite prior exposure to concentrations of NEU. The adverse group displayed no difference in MNPCEs compared with the negative control.
Conclusion. The ENU induced genotoxicity depending on its concentration. The extract displayed a profound capacity to prevent genotoxicity and alleviate leukaemia with good tolerance.
Childfree Dalam Pandangan Islam
Authors: Fadhilah Eva 
Published: December 2022

Childfree menjadi sebuah isu yang hangat diperbincangkan dikalangan masyarakat khususnya pasangan muda. Childfree adalah sebuah kesepakatan yang dilakukan oleh pasangan suami isteri untuk tidak memiliki anak selama masa pernikahannya. Padahal selama ini dalam kontruksi budaya masyarakat Indonesia, anak dianggap sebagai satu anugrah yang berfungsi sebagai perekat keharmonisan sebuah keluarga sehingga kehadirannya senantiasa dinanti-nantikan oleh pasangan yang sudah menikah bahkan keluarga besarnya. Dengan pendekatan normatif al-Qur’an dan Sunnah dapat diketahui bahwa memiliki keturunan adalah sebuah anjuran dalam Islam bukanlah sebuah kewajiban. Sehingga childfree tidak termasuk pada kategori perbuatan yang dilarang, karena setiap pasangan suami istri memiliki hak untuk merencanakan dan mengatur kehidupan rumah tangganya termasuk memiliki anak. Kendati demikian, meski tidak ada ayat yang secara langsung melarang childfree, sebagai manusia yang meyakini Allah SWT, pilihan untuk childfree bisa dikatakan sebagai pilihan yang tidak bijaksana karena Allah SWT menjamin kelangsungan hidup setiap hambanya. Tegas disebutkan bahwa dalam Islam anak dipandang sebagai anugrah yang harus disyukuri karena anak adalah pemberian Tuhan. Setiap manusia yang diberikan amanah menjadi orangtua harus menjalani peran tersebut dengan baik dan totalitas.Kata kunci : Childfree, Hukum Islam, Anak, Pernikahan, Al-Qur’an dan Sunnah
