Influence of the composition, structure, and physical and chemical properties of aluminium-oxide-based sorbents on water adsorption ability

Interaction between the water adsorption ability of aluminium-oxide-based sorbents and their chemical composition, acid-base properties of the surface, and textural characteristics has been analysed. Alumina desiccants were synthesized with the centrifugal-thermal activation of gibbsite followed by the hydration of the gibbsite under mild conditions. It was demonstrated that the multicyclic adsorption regeneration of samples under realistic conditions results in structural transformations and changes in the acidity of their surfaces and water adsorption ability. The modification of pseudoboehmite with alkali ions increases surface basicity and the dynamic capacity of adsorbents relating to water vapours. Equations have been presented that describe the adsorption and desorption processes taking place during water vapour adsorption with the materials studied

The Threat and Fear of War: The State and Politics in American Mass Media

The cultivation of political fears of the state and radical change of attitudes in the minds of people is possible in certain socio-political and economic conditions and massive propaganda in the mass media. The concept of political fear is insufficiently studied in psycholinguistics. This article is dedicated to exploring the political fears of the state in the modern American mass media. This research uses hypothetical-deductive and inductive methods, methods of definitional, interpretative and subjective analysis, and content analysis. It is found that in the modern American mass media, political fear of the state is revealed in fear of war and competition. To verbalize the horror of war and struggle, politicians in power use various tactics of agonal function as the main means of impact on opponents

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery

Customs Regulation of Cross-Border Movement of Goods Containing Intellectual Property Objects in the Context of Eurasian Integration

A condition for the effective integration of Eurasian Economic Union member states economies is creating a set of mechanisms for the use of intellectual property objects in modern circumstances. With significant intellectual potential existing in the EAEU countries, the process of commercialization and use of intellectual property objects is not carried out sufficiently. Considering the main purpose of the Union's functioning, this problem has to be solved comprehensively and consistently. The article presents the main results of study of customs regulation system of goods containing intellectual property objects crossborder movement in the context of Eurasian integration. It is noted that the violation of intellectual property rights occurs not only among competing companies as a plagiarism or industrial espionage, but also within framework of agreements concluded between copyright holders and users of intellectual property rights. The EAEU countries cooperate and organize interaction of authorized bodies also to form a unified system of intellectual property rights protection within the EAEU, SCO, BRICS, as well as the WTO. In order to improve the system of customs control of goods containing intellectual property objects, constant adjustments and modernization of methods for controlling the intellectual property objects movement across the customs border of the EAEU are required to ensure the maximum possible protection of intellectual property holders from illegal actions of third parties.

Oxidative destruction of organic pollutants on the polypropylene fiber modified by nanodispersed iron

This study aims to solve the problem of deep destruction of organic pollutants in industrial effluents by creating new composite materials with prescribed functional properties. This paper researches the possibility of using composites based on a polypropylene fiber under conditions of photocatalytic degradation of organic pollutants in aqueous and aqueous-organic media. Dye that are water soluble (eosin, brilliant green, rhodamine C) and fat-soluble (blue, yellow and red) have been chosen as organic contaminants. Composites based on the polypropylene fiber have been obtained by introducing nanodispersed iron onto the surface of the initial polymer, using ion implantation and super high frequency irradiation methods. The obtained composites are characterized, and their photocatalytic activity is studied with respect to the pollutants under study in the conditions of the Fenton-like system and visible radiation. The results show that the obtained composite materials are effective catalysts for oxidative photodestruction of organic dyes in aqueous and aqueous-organic media, and their decolorization degree reaches 80–100%
