    Abstract We examine possible reallocation effects generated by the COVID-19 outbreak by analyzing the patterns of venture capital (VC) investments around the globe. Using transaction-level data and exploiting the staggered nature of the spread of the virus, we document a shift in VC portfolios towards firms developing technologies relevant to an environment of social distancing and health pandemic concerns. A difference-in-differences analysis estimates significant increases in invested amount and number of deals in such areas. We show heterogenous effects related to the experience of VC investors, as well as their size and organizational form.

    Abstract Experimental data on the passing of signals from navigation satellites of the L1 range through forest plantations with an anisotropic horizontal tree arrangement structure are presented. A feature of the studied environment is an irregular distance between trees in rows and a constant distance between rows. Signals were recorded by an antenna located inside the forest at heights of 0.5 and 10 meters. Based on the results of processing the amplitude-time dependences of the recorded signal by means of fast Fourier transform, qualitative differences were revealed depending on the orientation of the probe signal path in the forest stand.

  3. Article: Microbiological approach for identification of wool clothes in ancient burials

    Abstract We propose a microbiological approach for the identification of wool clothes in ancient burials. The method is based on counting the number of wool-decomposing fungi colonies in soil that grow on nutrient media with keratin. The high number of colonies of keratinolytic fungi indicates the former presence of keratin-containing substrates in the burials. The method was tested on soil samples collected from under skeletons from burials of the Bronze Age and the Archaic time period. In each burial, the soils under the skull, spine, pelvis, knees and feet of the buried were examined. In all burials, the number of colony-forming units of wool-decomposing fungi was higher than that in the control samples from the upper layer of the burial soils. A significant increase in wool-decomposing fungi colonies was found in the soils under the feet of skeletons in the burials of the Bronze Age. In burials of Archaic Greece times, the smallest numbers of wool-decomposing fungi were found in the soil under the feet, and the highest numbers were found in the soil under the spine and knees. The differences in the distribution of the number of keratinophilic fungi colonies in burials indicate differences in the clothing of dead persons.

    Abstract The results of research of the possibility of strengthening with ferroconcrete of underwater part of worn-out steel hulls of the cleaning station and the dock owned by the public company "LORP" are given. Strengthening of the underwater part of the hull of the cleaning station ZK-7 and the dock SMD-10 helps to restore their durability and water resistance for further exploitation during 20 years and more with rather small material consumption, labour intensiveness and monetary costs in comparison with the common replacement of the worn-out metal constructions into new ones.

    Abstract After preliminary ab initio calculations, 3-phenacyl substituted thiazolium salts, analogs of Alagebrium, were synthesized and investigated in vitro as glycation reaction inhibitors. The most part of investigations focused on the potential of the title compounds to attenuate the formation of fluorescent AGEs as well on their ability to disrupt the cross-linking formation among glycated proteins. Additionally, the capability of thiazolium salts to deglycate in the reaction of early glycation products with nitroblue tetrazolium was determined. Cytotoxicological properties of the title compounds were evaluated using LDH and MTT assays. The leader compound (3-[2-(biphenyl-4-yl)-2-oxoethyl]-1,3-thiazol-3-ium bromide) in a 50 mg/kg dose (p.o. 14 days) was further tested within an in vivo carbonyl stress model (rats, methylglyoxal 86.25 mg/kg/d, i.p., 14 days). As a result, the leader-molecule revealed a high effectiveness against all three examined mechanisms of glycation reaction inhibition in in vitro tests and was able to suppress capacity of methylglyoxal to form AGEs in vivo.

    Abstract The synthesis and structural characterization of α-haloalkyl-substituted pyridinium-fused 1,2,4-selenadiazoles with various counterions is reported herein, demonstrating a strategy for directed supramolecular dimerization in the solid state. The compounds were obtained through a recently discovered 1,3-dipolar cycloaddition reaction between nitriles and bifunctional 2-pyridylselenyl reagents, and their structures were confirmed by the X-ray crystallography. α-Haloalkyl-substituted pyridinium-fused 1,2,4-selenadiazoles exclusively formed supramolecular dimers via four-center Se···N chalcogen bonding, supported by additional halogen bonding involving α-haloalkyl substituents. The introduction of halogens at the α-position of the substituent R in the selenadiazole core proved effective in promoting supramolecular dimerization, which was unaffected by variation of counterions. Additionally, the impact of cocrystallization with a classical halogen bond donor C

    Abstract Energy saving potential is quite huge in the most sectors of the national economy, particularly in housing and utilities and industry. Due to this, energy efficiency increase at the enterprises of housing and utilities and industry through the energy efficiency programs implementation, is one of the priorities in the modern economy of Russia and its regions, and requires radical measures to improve the effectiveness of its implementation. The purpose of the authors is the scientific and practical study of the main problems of energy efficiency programs implementation at the enterprises of housing and utilities services and industry in modern conditions. To achieve this purpose the authors solved the following problems: the current state of the housing and utilities sector and industry, the relevance and the need for energy saving policy at the enterprises of housing and utilities services and industry are studied; the main problems impeding to implement the energy-saving program effectively at the enterprises of housing and utilities services and industry are determined; the possible ways of solving the problems identified in the energy efficiency programs implementation at the enterprises of housing and industry are offered. The team of authors focuses in this study on the problems of the energy audit using in practice as a basic tool for the energy saving programs development at the enterprises of housing and utilities services, industry and their subsequent implementation. The subject of author's researches is the factors that determine the energy efficiency programs implementation at the enterprises of housing and utilities services and industry at the level of individual region and the whole country, and the object is the enterprises of housing and utilities services and industry. Methodologically the scientific and practical research is based on the complex approach using the methods of comparative, statistical and logical analysis.

    Abstract Chalcogenodiazoles have been intensively studied in recent years in the context of their supramolecular chemistry. In contrast, the newly discovered cationic 1,2,4-selenodiazole supramolecular building blocks, which can be obtained via coupling between 2-pyridylselenyl halides and nitriles, are virtually unexplored. A significant advantage of the latter is their facile structural tunability via the variation of nitriles, which could allow a fine tuning of their self-assembly in the solid state. Here, we explore the influence of the substituent (which derives from the nitrile) and counterions on the supramolecular assembly of cationic 1,2,4-selenodiazoles via chalcogen bonding.
