This work is devoted to the study of conversion of anisole, as one of the lignin monomers, in the presence of catalysts synthesized by the hydrothermal method. Platinum and palladium catalyst deposited on the polymer matrix of hypercrosslinked polystyrene allowed achieving about 90% of anisole conversion. It was shown that during the conversion of anisole, cyclohexane, methylcyclohexane and phenol are the main products. The highest selectivity (approx. 88%) with respect to cyclohexane was shown by a platinum catalyst supported on hypercrosslinked polystyrene. The palladium catalyst showed lower selectivity for cyclohexane (approx., 68%), however, analysis of the reaction mixture revealed an increase in the content of methylcyclohexane. Thus, the use of catalysts synthesized by the hydrothermal method in the processing of biomass components is a promising direction for the development of biofuel production technologies.

From the point of view of rational resource management polymer composites treatment is at the same time environmental pollution prevention during their burial and the opportunity to recover valuable resources — fibers and other fillers. This article presents an analysis of the various processes of thermal utilization of carbon fiber reinforced composites. Incineration technologies in specialized installations and in cement production kilns allow to get rid of the significant amounts of a wide variety of wastes, including polymer composites, with useful energy potential, therefore, it is a popular way to solve the problem of such materials in a place where their disposal is prohibited. However, in this case, valuable resources, like carbon fiber, which production is very energy–consuming, are lost. Therefore, the priority is technologies that allow recycled carbon fiber recovery. One of the most widely used methods that meet most requirements is pyrolysis; therefore, investigation of optimal conditions for this process is an urgent task for research.

In the work, the measurement of the solubility of synthesis gas was carried out in the temperature range of 100–300 °C and pressure range of 1.0–5.0 MPa. n–dodecane was used as a solvent, as it is one of the most frequently used solvents in the liquid–phase Fischer–Tropsch synthesis. Based on the results obtained in the work, thermodynamic parameters of absorption were calculated, such as the Henry constant, absorption enthalpy and apparent activation energy of absorption. The phase equilibrium was calculated using the Soave–Redlich–Kwong cubic equation of state. It was shown that the SRK cubic equation of state can be used to predict the optimal process conditions for the liquid–phase Fischer–Tropsch process. The applicability of the data was confirmed by experiments on the variation of temperature and pressure in the synthesis of hydrocarbons from synthesis gas on a cobalt catalyst supported on silica.

The preservation of the genetic diversity of a species is possible only if the gene pool of its populations is preserved. Particularly important are studies of patterns of distribution of genetic variability for species that occupy vast areas and are of economic importance, such as species of the genus Larix Mill. The purpose of this study is to analyze the genetic diversity and structure of some populations of L. sibirica of Ural based on intermicrosatellite polymorphism. Using the ISSR markers, the genetic diversity and structure of 6 natural populations of Siberian larch L. sibirica in the Urals were analyzed. The analysis revealed 120 ISSR markers, of which 116 were polymorphic (P95=0.967). The main parameters of the genetic diversity of populations were determined and it was shown that the Ural populations of Siberian larch are characterized by a higher genetic diversity. At the same time, the highest rates of genetic diversity were found in the VSN population (P95=0.923; HE=0.236; ne=1.388), while the ISH population was the least diverse in all indicators (P95=0.826; HE=0.191; ne=1.321). The studied populations of L. sibirica of the Urals are largely differentiated, most of the entire observed genetic diversity is concentrated within populations. The structure of populations is generally close but does not fully reflect the geographical location of the studied populations. The findings suggest the existence of genetically differentiated populations and their groups in L. sibirica in the study region and will be important for the development of an effective strategy for the conservation and reproduction of valuable tree species of plants.

This literature review focuses on non-alcoholic fatty liver disease (NAFTLD). Today, the world practice of researching diseases is characterized by a multifactor approach, in particular, it concerns pathologies, which are based on a cascade of metabolic disorders, where insulin resistance is one of the key places. Today, NAFTLD is considered an integral part of the metabolic syndrome. The frequency of occurrence of NAFTLD varies from 14 to 26%, in addition, 10% of patients show signs of steatohepatitis non-alcoholic etiology. The pathogenesis of steatosis and metabolic steatohepatitis is poorly studied and there are very contradictory data in the literature, which served as the basis for the creation of this review. The authors consider in detail the historical aspect of the formation of the NAFTLD as an independent nosological unit. A number of etiological aspects of the formation of NAFTLD, but to a large extent, the review is devoted to the mechanisms and pathogenesis of the formation of NAFTLD. A concept has been put forward that reflects the role of oxidative stress and the death of mitochondrial complexes in initiating the initiation of apoptosis and/or necrosis of hepatocytes (under these conditions there is an activation of leukocytes and Ito cells in Disse space, which contributes to the fibrosis proliferation and the formation of NAFTLD). Also, in this paper, there is also a place for searching for the cause-and-effect relationships of such comorbid diseases, such as NAFTLD and carbohydrate metabolism disorders.

The investigation of linear erosion forms was carried out at the city of Quito (Equatorial Andes). The study was aimed to define the correlation between rill forms with different length parameters in the key-site area located nearby Zabala. It is stated that the rill forms with the length up to 50 m (58%) prevail. The gullies with the length of more than 200 m make 9% of all rill forms. Nevertheless, these gullies, as a rule, create main channels that provoke the formation of multiple side forms in the process of regressive erosion. The further development of the linear erosion causes the dissection of the investigated area that increases the risk for landslide developments.

The discoveries of Russian scientists in the middle of the last century in the basic sciences gave a powerful impetus for the innovative development of the entire world economy. Along with a breakthrough in the field of cosmonautics, aviation, semiconductor electronics, laser technologies are the most important and alternative methods of processing a wide range of materials. The analysis carried out in the work showed that Russia is currently significantly inferior in the production of both equipment and the application of laser technology. The demand for domestic enterprises is mainly satisfied with the supply of foreign equipment and technology. Foreign companies producing laser equipment used the discoveries and inventions of domestic researchers to manufacture their own lasers, which, at the moment, are widely introduced into the Russian economy. In this paper, studies of the laser technology and technology market were carried out, in particular, an analysis was made of the demand for laser technology in Russia by industry and technology operations, the areas of their application were indicated, the main trends and development trends of the Russian laser technology market were identified. The analysis showed that the backlog of Russian developments in this area is critical and to eliminate the technological gap that has arisen, resources should be focused on the identified strategic areas that have the greatest impact on the innovative development of the Russian economy. The most promising direction of development in laser technology can be called fibre and diode lasers, which, at the moment, are actively gaining popularity. The state support necessary for the development of domestic laser technologies should consist in subsidies to pay part of the interest on loans for the implementation of new investment projects in various industries, provide tax benefits to enterprises using laser technology, thereby stimulating the demand for laser technology, as well as supporting human resource development.

This article analyzes current problems in public procurement, as well as ways to solve them. The focus is on the modernization and improvement of the contract system, as well as the threat of competition in the government procurement market. The relevance of considering this topic at the present stage is expressed in the need to apply tough measures to combat corruption in the field of public procurement, it justifies the need to improve legislation, due to the difficulties encountered in the implementation of state financial control in the field of procurement. The article describes the complexity of the organization of procurement, identifies ways to optimize them. The main ways of the impact of certain negative trends on the implementation of the contract system of the Russian Federation are proposed. Improvement and modernization of the legal framework in the field of public procurement will always be relevant since the social, economic and political spheres of relations in the global economy are changing and not constant. That is why, basically, it is necessary to create a fundamental legal structure, to which, as far as it would be important, minor amendments will be made, and not urgent and global in a short period of time. The main objectives of regulating the law on the system of contracts are its openness and effectiveness, therefore, reducing corruption and reducing the cost of budget funds, “healthy” competition, timely and high-quality satisfaction of state and public needs, access to the process of perception of procurement stages for professionals and its participants. To understand the supplier in all the intricacies of the contractual system, it is necessary to analyze and study a large number of laws and regulations. The results showed that in order to minimize problems in the field of public procurement, it is necessary to intensify the interaction of regulatory and law enforcement agencies and improve legislation.

The article examines the international legal regulation of the legal status of minors sentenced to imprisonment. The analysis of the norms, recommendations and principles in the field of enforcement of sentences, which are internationally accepted and binding on the states that have joined them, has shown that international standards are classified into general acts and specialized acts. The study of international norms, rules and standards regarding the treatment of minors sentenced to imprisonment and their implementation at the level of lawmaking and practice in the penitentiary system of the Russian Federation suggests that not all international norms are implemented in the domestic legislation and practice of imprisonment in respect of minors. The author of the article concludes that criminal punishment in relation to this category of convicts should perform not only punitive, but also educational function in order to increase the efficiency of the process of re-socialization in the process of serving the sentence, and after his release, reduce the recurrence of crimes.

The article is devoted to a resonant, but unfortunately, relevant topic in the legal space of many states — the abolition of adoption. The article analyzes this institution not only from the point of view of the legal regulation of the consideration of cases concerning the cancellation of adoption by courts of general jurisdiction, but also the psychological aspect of resolving such disputes. The authors unequivocally conclude that the success of the judicial procedure in these categories of cases depends not so much on correct, timely actions performed by the court itself, but rather on the presence in the process of persons with the necessary knowledge and skills (psychologists) who are able to provide the court with the true information about the psychological state of the child in respect of which the question of the abolition of adoption. Also, the authors have repeatedly argued in the article about the necessity of imposing a mandatory pre-trial procedure on mediation whenever possible, and ideally an extrajudicial procedure for resolving cases, on cases of cancellation of adoption. Where in this procedure the leading role would be assigned to a psychologist–a mediator who, in the process of working with the parties, corrected their behaviour and possibly led to the most favourable outcome for the adopted child. The need to use mediation and other conciliation procedures in relation to adoptive parents and adopted children is stated. The authors also in the article consider the international experience (by example) of Japan, which allows concluding that the legislation of the Russian Federation is more perfect, but still requires further refinement. The need to improve legislation is stated and specific solutions to the existing gaps are provided.
