REVIEW:APPLICATION OF BIG DATA AND IOT PROTECTED MODE IN AGRICULTURE

Advance researches in the field of Internet of Things (IoT) are helping to make water management smarter and also used for optimizing consumption in the smart agriculture industry. Now days the development and research in Intelligent Smart Farming IoT based devices is turning the face of agriculture production in enhancing as well making it cost-effective and reducing wastage. To create environmental conditions suitable for the growth of animals and plants, modern agriculture that uses artificial techniques to change climatic factors such as temperature a highly efficient protected agriculture mode is used. To handle the increasing challenges of agricultural production, the complex agricultural ecosystems need to be better understood. Modern digital technology used for continuously monitoring the physical environment and producing large quantities of data in an unprecedented pace. For improving productivity the analysis of big data would enable farmers and companies to extract value from it. Moreover big data analysis is leading to advances in various industries; it has not yet been widely applied in agriculture. The objective of this paper is to perform a review on current studies and research works in agriculture which employs the recent practice of big data analysis, in order to solve various relevant problems.

Whose Virus - Whose Code

This essay attempts to trace the currents of anxieties and fears that overflowed the digital during the early stages of the Covid-19 pandemic. Traveling with such flows, this work aims to model the questions that, circulating silently in a sort of latent state before the catastrophe, now haunt us as brutally unveiled; namely, to which extent the digital mediations we have attached to ourselves, to our lives, in order to know and experience this world under a protected mode, now push us to witness that that world has expelled us? To which extent these digital mediations tell us that now we belong more to them, than to that old world of which we became blind almost a century ago? Through a post-hermeneutical approach, one that analyzes some of the digital traces left by the rise of this pandemic by discussing them through the lens of media history and media theory, this work seeks to sketch a short media history of loss; the loss of many, the loss of our-selves.

Microbial Metabolic Genes Crucial for S. aureus Biofilms: An Insight From Re-analysis of Publicly Available Microarray Datasets

Bacterial biofilms are microbial lifestyles found in all environments. Up to 80% of human infections and 60–70% of hospital-acquired infections have a biofilm origin, with Staphylococcus aureus one of the leading causes of these infections. Microorganisms in biofilms exhibit significant antimicrobial resistance which poses important treatment challenges, hence the urgent need to identify novel antibiofilm strategies. Microbes form biofilms in response to various factors, and once these 3-dimentional structures form they are highly recalcitrant to removal. The switch from planktonic lifestyle to the biofilm protected mode of growth results in a phenotypic shift in the behavior of the microorganisms in terms of growth rate and gene expression. Given these changes, investigation of microbial gene expression and their modulation at different stages of biofilm maturation is needed to provide vital insight into the behavior of biofilm cells. In this study, we analyzed publicly available transcriptomic dataset of S. aureus biofilms at different stages of maturation to identify consistently upregulated genes irrespective of the biofilm maturation stage. Our reanalysis identified a total of 6 differentially expressed genes upregulated in both 48 and 144-h old S. aureus biofilms. Functional analysis revealed that these genes encode for proteins which play a role in key microbial metabolic pathways. However, these genes, as yet, are unrelated or fully studied in the context of biofilm. Moreover, the findings of this in silico work, suggest that these genes may represent potential novel targets for the development of more effective antibiofilm strategies against S. aureus biofilm-associated infections.

Demutation of the Volga meadow steppes in a reserve

The paper deals with the problem of restoring rare communities of meadow steppes after plowing using the example of the Volga forest-steppe state nature reserve. The author has studied 9 uneven-age deposits in three forest-steppe protected areas: Kuncherovsky 5, Poperechensky 2 and Ostrovtsovsky 2. The study of deposits of different ages was carried out by the method of periodic large-scale geobotanical mapping using modern GIS-technologies. Maps of vegetation of different scale (1:5000, 1:10000, 1:25000) have been created. Deposits areas that adjoined to the virgin steppe were studied by a method of geobotanical profiling. At the same time, profiles (out of 1025 sample plots of 4 m in size) were laid at a distance of 10 m from each other. About 500 geobotanical descriptions were made at 9 different-age deposits at different times. Restoration of meadow steppes is impossible without the introduction of elements of anthropogenic intervention (moderate grazing and regulated haying) into the existing protection regime. Restoration of the steppes in an absolutely protected mode is possible only on the slopes of the southern exposure in forest-steppe landscapes of erosion-denudation plains (Kuncherovskaya forest-steppe).

Land use limitations: environmental and socioeconomic impacts

Land use regulation is one of the most important state tasks and is aimed to ensuring the sustainable development of settlements. One of the mechanisms to solve this task is land use limitations establishment by restricted the possibility to carry out some activities, on certain territories or separate land plots, which would lead to negative ecological and social consequences. Such activity is becoming more and more urgent in the face of increasing ecological problems. Land use limitations could be considering in different areas. On one hand, the feasibility of land use is governing by the methods of spatial planning, based on natural and anthropogenic conditions. On the other hand, land use limitations are the result of location of object is which could be either source of negative influence or the object is requiring being protected (mode-forming objects). The aim of the article is to determine the impact of land use limitations on the various components of society, taking into account the environmental, economic and social components of sustainable development. Environmental and socioeconomic impact of land use limitations formation on the example of limitations caused by the activity of a mode-forming object are described in the study. The results of the study illustrate that the establishment of limitations on the land use can solve mainly environmental and social problems.

Realization of the power-system protection functions for digital power stations and using of Elbrus computers

The relevance of this study is justified by the introduction of digital transformers to modern electrical substations and the need to create relevant digital systems for the automatics relay protection. The article discusses the basic principles of automatics relay protection of the digital electrical substations. The authors examine the problems of its implementation with the use of embedded systems based on domestic computing systems of the Elbrus family with the support of a protected mode of program execution. They suggest an architecture of the user program for managing the automatics relay protection system at a digital substation. Based on the architecture of user tasks and the requirements of the industrial standard, the authors form the restrictions imposed on the software and hardware of the computing systems used in embedded systems in the industry. This paper presents some results of the protected mode in real problems of automatics relay protection at digital substations. The study demonstrates the advantage of using protected mode in creating programs that control industrial facilities. The authors consider the effect of protected mode on the performance and fault tolerance of the target system.
