Algae biomass is considered as an alternative raw material for the production of biofuels. The search for new types of raw materials, including high-energy types of microalgae, remains relevant, since the share of motor fuels in the structure of the global fuel and energy balance remains consistently high (about 35%), and the price of oil is characterized by high volatility. The authors have considered the advantages of microalgae as sources of raw materials for fuel production. Biochemical and thermochemical conversion are proposed as technologies for their processing. This paper presents the results of the study of the pyrolysis of the biomass of clonal culture of blue-green microalgae / cyanobacteriumArthrospira platensis rsemsu 1/02-Pfrom the collection of the Research Laboratory of Renewable Energy Sources of the Lomonosov Moscow State University. An experiment to study the process of pyrolysis of microalgae biomass was carried out at the experimental facility of the Institute of High Temperatures RAS in pure nitrogen grade 6.0 to create an oxygen-free environment with a linear heating rate of 10 ºС / min from room temperature to 1000 ºС. The whole process of pyrolysis proceeded in the field of endothermy. The specific amounts of solid residue, pyrolysis liquid and gaseous products were experimentally determined. As a result of the pyrolysis of microalgae biomass weighing 15 g, the following products were obtained: 1) coal has the mass of the solid residue is 2.68 g, or 17.7% of the initial mass of the microalgae (while 9.3% of the initial mass of the microalgae remained in the reactor); 2) pyrolysis liquid – weight 3.3 g, or 21.9% of the initial weight; 3) non-condensable pyrolysis gases – weight 1.15 l. The specific volumetric gas yield (the amount of gas released from 1 kg of the starting material) was 0.076 Nm3/ kg. The analysis of the composition and specific volume yield of non-condensable pyrolysis gases formed in the process of pyrolysis, depending on temperature. It is shown that with increasing temperature, the proportion of highcalorie components of the gas mixture (hydrogen, methane and carbon monoxide) increases. The calorific value of the mixture of these gases has been estimated.

The focus on sustainability is at its peak in the construction industries in the last couple of decades. That includes green constructions such as rammed earth construction. Due to media exposure and carbon emission, people are undeniably turning to green and sustainable buildings. Furthermore, there is an improper management pattern of solid waste management found in developing countries, such as open burning and dumping of solid wastes. In which paper waste is not handled in a good way. There arefew places in developing countries where developing countries follow proper management of solid waste. Paper waste is present in each city because people are using it for daily life. Paper waste has fibre in them and has cellulose content. These components of paper waste are suitable for compressive strength. It has a side effect that it increases water absorbability. The reason for this research work is to reduce paper waste and reduce cement content. This paper also aims to find the durability and strength properties of rammed earth construction.

The aim of this article is to reveal the main reasons for the irrational behaviour of economic agents during the COVID-19 coronavirus pandemic in terms of behavioural economics and opportunities for change such a behaviour.The article reveals the approaches that were used in 2020 and continue to be used today as the main ones to prevent the spread of coronavirus infection. Despite the existence of such prescriptions, the infection continues to spread and causes negative socio-economic consequences.Thus, the main reasons, the resistance of citizens to the measures recommended by governments around the world and the manifestation of deviant behaviour among the seemingly “rational” economic agents were analyzed.The main reasons and possible factors for changing such a behaviour are the postulates of behavioural economics, such as the effect of reinforcement effect, conservative bias, confirmation bias, conditional cooperation, the preference of beliefs consonance.In addition, this paper provides a brief overview of some post-material values of Ukrainian society based on global research and offers an assessment of the dependence of these values on the incidence of COVID-19 and an explanation in terms of behavioural economics.The article notes that the presence of certain established views on the “normality” of preventive antivirus measures may affect the propensity or the lack of propensity to adhere to the necessary protective behaviour by economic agents.The research methods are descriptive, analytical, methods of synthesis and comparison. As a result of the analysis, the article proposes a comprehensive approach to men’s behaviour during the pandemic according to behavioural economics.The study concludes that the main task to improve the effectiveness of preventive measures for the spread of COVID-19 today is to understand the causes of irrational behaviour in new circumstances in terms of behavioural economics and apply the theory of “pushing” or “nudging” to form positive social economic change. It is suggested to use this paper for further and deeper practical research of certain aspects of changing people`s behaviour for better work effectiveness and wellbeing.

Abstract Today, in carrying out the reforms for the development of our society, there are created full opportunities and conditions for the fulfillment of the tasks set before the Uzbek linguistics, purposeful research work is carried out on the issue of comprehensive study of our language. At the same time, the study of the features of Uzbek dialects, relying on the theoretical bases of areal linguistic research, is defined as one of the priority directions in the historical-comparative and ethnolinguistic aspects.This sphere consists of imperfect, simple descriptive and illustrative aspects, indefinite places need to learn and fill on the basis of new views, from a mental point of view. The article gives an idea of the peculiarities of the Namangan Kipchak and Karluk dialects, the historical genesis of the system of vowels, the issues areal of their prevalence and application. The phonetic-phonological linguistic character of the dialect is a comparative-historical reflection of the processes of events of features and laws. In its turn, there are described opinions about the events of umlaut in the Turkic dialects of synharmonism and Karluk dialects in Kipchak dialects related to the vowels in the Turkic languages. Key policy insights.The study through areal-typological and areal-linguistic methods, which gave Mahmud Kashgariy in Turkic languages, the initial point of any linguistic theory and conceptions, the study of dialects, their specific features, is still one of the important issues today. The emergence of areal linguistics has opened up a wide way to evaluate new issues and concepts in the field of dialectology, to solve them in new ways. Relying on the theoretical basis of dialect and slang areas in the holistic study of the language system, the fact that historical-comparative and ethnologic research is defined as one of the priority areas imposes new responsibilities on Uzbek linguistics and Uzbek linguists.

The paper provides an overview of the evolution of Social Sciences with a focus on the Post-1945 period, known for major strides towards scientific, analytical, nonpartisan, multi-disciplinary and comprehensive study and research in different fields of Social Sciences. The paper discusses the gradual growth of Social Sciences in Pakistan in terms of increase in number of persons engaged in teaching, research and practice in various domains of Social Sciences, institutional facilities and availability of funds. There is a discussion of the major features of the research work done in Social Sciences in Pakistan and its weaknesses and deficiencies. The paper argues that Social Sciences have become important for societies like Pakistan that face different types of social and political conflicts. The rise of religious extremism, violence and terrorism also requires that we benefit from the work done in different fields of Social Sciences for understanding the dynamics of societal trends, issues and conflict and how to address them. The paper also reviews teaching and research being done in Pakistani universities, especially since 2005, when more funds became available for study and research in Social Sciences. The universities have vastly expanded their Doctoral and M.Phil. porgrammes but the imperative of quality is often neglected.

This chapter reports the results of a theoretical and practical research work on simulation, both as a teaching strategy that creates a dynamic and experiential situation which enables participants to take on roles in relation to the variables to be tested or modified, and the learning content that the students need to acquire. With reference to the training and educational needs of contemporary society, the theoretical premises underlying simulation are considered and examined in relation to recent findings regarding the process of learning and teaching and the acquisition of knowledge, as well as some recent research results. On the basis of the findings, it appears necessary to reflect on the synergy triggered through simulation. It particularly emphasized the role of simulation in the integration of different skills and types of knowledge, leading to the overcoming of the compartmentalization of knowledge and its fragmentation into discrete subjects or disciplines. Questions remain open regarding the role of ICT in the whole simulation process.
