This, in turn, leads to an increase in crimes such as bribery, fraud, theft, various misdeeds in society.  This article discusses the role of religious values in combating and preventing the above-mentioned vices through religious values.

Optoelectronic sensors based on anomalous photo-voltage (APV) curtains derived from semiconductor compounds are attracting the attention of many experts today. The use of APV receiver as the first converter in automated systems allows to increase the efficiency of a number of parameters of the system, such as energy saving, reliability, speed, accuracy.

In the article, there is the scheme and principle of the work of the cotton cleaner from small litter includes a composite pin drum with elastic elements and a vibrating mesh surface on elastic hinges. Theoretically, the torsional-vibrational motion of a two-mass system of a composite shoe drum has been studied, and the regularities of the dependence of changes in the parameters of the pin drum have been obtained. Based on the approximate analytical solution of the integro-differential equation, the law of angular vibrations of the net surface on the elastic supports of the cotton cleaner is studied. Experimental studies revealed regularities of loading and a change in the speed of rotation of the drum. The results of the full-factor experimental studies of the sample of the composite fluke drum are given. Based on the study of each of the three factors on the changes in the cleansing effect of cotton, the graphical dependencies of the parameters are postrene. The best values of the factors at which a high purifying effect of cotton from small weeds are achieved are recommended. Production tests revealed that the cleaning effect in comparison with the existing version of the drum spindle in the recommended increases by an average of 2.7%.

The family is the priority of any state that is interested in preserving its people, strengthening its international status and all socio-cultural institutions. Family and marriage themes within the framework of the humanities are explained not only by the expansion of the problems and objects of these sciences, but also by the need to strengthen the family as the foundation of society.

Without the support of the family, many social problems cannot be resolved: the upbringing of the future generation, the transmission of life values, the fight against crime, despotism, mental illness. Domestic violence is a serious social problem that poses a direct threat to life for every person and society [7]. Violence in general, and family violence in particular, is not only an attempt on life and health, but also a violation of the constitutional right of a person to protect his dignity. This problem is the object of scientific research in sociology, psychology, jurisprudence and other disciplines.

Observations have shown a decline in the prestige of family values, an increase in the number of divorces, a decrease in the birth rate, an increase in the number of dysfunctional and so-called problem families, etc.

The article provides a psychological classification of families that differ in their characteristics and family relationships. The results of a survey conducted among specialists working with families are analyzed, with the help of which the consequences of negative attitudes, domestic violence are revealed and indicators of various types of violence are compiled.

This article reveals not only the types of violence, but also the factors affecting family relationships. The results of the study carried out among members of young families and the psychological analysis of the results obtained are presented. The necessary recommendations for the prevention of domestic violence and measures to strengthen the family were given.

In the article, the author analyzes emergencies at power plants in Uzbekistan, including research by scientists who conducted their research on extinguishing and localizing fires with the use of appropriate technical means at energy facilities, taking into account the observance of safety measures for energy facilities that have the property of electric shock to firefighters.  In addition, the author provides a mathematical analysis of a fire event using the multi-interval method and formulates the appropriate conclusions. At the same time, the author proposes the use of the latest information technologies in extinguishing fires of this kind.

The article describes the importance and relevance of macroeconomic modeling in the development of economic sectors. The problems of applying the methods of macroeconomic modeling (both optimization and simulation) in the practice of planning and managing the national economy are analyzed.

The article tells about the relationship between aesthetic culture and spirituality, the formation of spiritual and moral qualities of a harmoniously developed personality in a civil society.

Tobacco and alcohol have long been acknowledged as carcinogens holding a critical role in the progression of a various cancers. Identifying the degree to which tobacco and alcohol can impact cancer mortality is necessary to developing effective public health strategies and mitigating risks with preventative measures. The goal of this study is to characterize the behavior of cancer mortality in response to shocks in alcohol and tobacco consumption utilizing aggregate U.S. data. This is the first study of its kind to examine the intertemporal relationship between cancer mortality and its determining factors within a dynamic system. Our results indicate cancer mortality displays persistence and its path dependency varies considerably between the shock factors. An unexpected shock to alcohol consumption results in cancer mortality taking about 17 years to return to its pre-shock level, whereas tobacco consumption shocks recover the original cancer mortality level in about 10 years. Alcohol has a more dominant effect on cancer mortality regardless of time dimension. As a result, policies that have been previously emphasized toward mitigating tobacco consumption may prove prudent in addressing alcohol as a public health concern with respect to cancer mortality.

In the researches has considered the principles of constructing a geo-information system based on modern GIS technologies, justified the boundary and initial conditions, developed a regional mathematical model of the Aydar-Arnasay Lake System (AALS) territory and implemented it on the basis of modern modeling programs Vizual Modflow for analyzing and assessing the dynamics of AALS development and its relationship with the components of the geological environment. The factors of groundwater formation are given and evaluated taking into account changes in water management conditions, their current state is highlighted and recommendations are given on substantiating the tasks of groundwater monitoring in these territories.

The paper presents the results of an experimental study of the influence of semiconductor LEDs on the aqueous environment. It has been shown that the use of semiconductor LEDs in fish farming is the preferred source of optical radiation in the development of microorganisms in natural or open bodies of water, in particular, in the growth of functional systems as aquatic plants, fish and their larvae, as well as moderate development of zooplankton, phytoplankton, detritus, which are the natural feed base of fish and their larvae.

Creating conditions for R&D in a post-industrial type of development is an extremely urgent task. Thanks to its scientific potential, the economy will be in a much more advanced position. The article examines the current state of research and development, knowledge economy and innovation. The factors of accelerated development of R&D in the knowledge economy are identified. The requirements for creating systemic prerequisites for the formation of the knowledge economy and innovation environment are discussed separately.

Since the last century concerns over environmental issues have aroused enormously. The rise of technology and advances in industry and mass production is causing irreversible damage to the environment. The mankind is to blame for the extinction of many species and the threats to the nature.
