Development of a mechanism for managing market strategies of the Russian metallurgical industry in modern conditions

The article is devoted to the search for solutions to adapt the strategic planning of the Russian metallurgical industry to modern political and economic conditions. The sanctions restrictions mutually applied against Russia by the countries of the European Union and the United States, and escalated in 2022, led to the destruction of established trade and financial flows, which seriously complicated the work of the Russian metallurgy. Therefore, the author of the article set the task to develop mechanisms for adapting the strategies of metallurgical companies to the current economic situation. The methodological basis of the current material was the analysis of annual reports of companies in the industry, as well as a number of works by Russian researchers devoted to the topic of modern development of metallurgy. It is noted that, despite the negative consequences of the prohibitive measures, the industry has promising sales markets and opportunities to maintain production volumes. The key results of the study were the data obtained on the share of metal exports and the structure of supplies to the foreign market. Ferrous and non-ferrous metallurgy are considered separately from this perspective, which is rare in modern research. In the course of the work, the current and prospective strategic directions for the development of the metallurgical industry were determined. A potential decrease in the interest of Russian companies in the environmental component of their activities, which was largely determined by dependence on foreign markets for debt capital and sales, was noted

Development of the ESG concept in the Russian power industry

The modern development of the energy industry, as well as other sectors of the economy, is impossible without an environmentally oriented approach. Therefore, the green energy direction has received a fairly wide development in the world in the last decade. This energy has less negative impact on the environment due to the fact that there is no need to use fossil fuels. Due to the significant reserves of these resources, the introduction of renewable sources in Russia is slower compared to the leading countries in the field of green energy generation. Attempts to close the gap in this direction appeared only in recent years. The article is devoted to the assessment of the environmental agenda in the Russian power industry. In particular, the authors consider the issues of reducing the consumption of resources for electricity generation, as well as give an overview of the distribution of renewable energy in Russia as a whole. The scientific novelty lies in the consideration of a number of technical and economic parameters of the power generating industry operation, as well as in the construction of time series based on the most important statistical indicators of the power industry. Their visual representation is based on the use of tabular and graphical methods of information processing. In addition, a review of the industry companies reporting in recent years regarding the implementation of ESG concepts was made

Gag in the works of Alexander Tatarsky

Cílem této práce je analýza tvorby režiséra a animátora Alexandra Tatarského. Zaměřil jsem se na osobnosti gagu v jeho animovaných filmech, v čemž navazuje na tradice němé grotesky a kde se naopak projevuje specifické uchopení tohoto komediálního tvaru. V teoretické části práce analyzují principy fungování gagu obecně, zkoumám biografii autora, specifikum jeho tvorby. V praktické častí pak analyzují, jakým způsobem s gagem pracuje tento režisér, a to demonstruji na analýze jeho filmů. Analýzou jsem došel, že gag je jedním ze základních elementů v tvorbě Tatarského, vyžaduje jednoduché scénáristické konstrukce a rozšiřuje možností využití gagu v rámcích animovaného filmu

FTIR Emission Spectra of Bacteriorhodopsin in a Vibrational Excited State

The membrane protein bacteriorhodopsin (bR) con tains retinal as its chromophore. In light adapted bR, retinal is in the all trans form covalently linked to the apoprotein at Lys216 by a protonated Schiff base. Photon absorption isomerizes the retinal into the 13 cis configu ration. This primary event is responsible for both trans membrane proton transfer and subsequent re isomeriza tion of retinal (see for review [1 3]). These two processes are characterized by high quantum and thermodynamic efficiency The functioning of bR is a cyclic process that is char acterized by sequential conversion of spectrally identified intermediates (J, K, L, M, N, and O); the exact number of intermediates and the pathways of their interconver sion remains unclear. Primary light induced stages are usually described by the following chain of events Vibrational spectroscopy (resonance Raman spec troscopy) and differential Fourier transformed infrared (FTIR) spectroscopy are the most popular methods employed for the molecular study of the structure and properties of bR. However, due to high contribution of water and protein backbone to bR absorption, it is very difficult to obtain the vibrational IR spectrum of the chromophore complementary to the Raman spectrum. The use of IR emission spectroscopy would overcome these difficulties; however, we do not know of results of such studies available in the literature. Infrared emission spectroscopy has great potential. Due to the development of highly sensitive Fourier trans form infrared techniques, it is widely used in physics and chemistry In the present work, we continue these studies; we were particularly interested in the study of the effect of 0006 2979/01/6611 1315$25.00 ©2001 MAIK "Nauka / Interperiodica" * To whom correspondence should be addressed.

Original Russian Text Copyright © 2001 Abstract-Vibrational IR emission spectra of bacteriorhodopsin (bR) were recorded under continuous illumination with vis ible light at room temperature. They contain selective information about the chromophore, Schiff base, and opsin. The spec tral bands were identified by comparing the data with resonance Raman and IR absorption data. The IR emission spectra were shown to contain a set of bands characteristic for both all trans (bR 568 ) and 13 cis conformations (K 610 like intermedi ate) simultaneously. Variation of spectral composition and the intensity of visible light illumination influenced the spectral traces and intensity distribution between them. Greater intensity of deformational vibrations suggests distorted retinal struc ture in the vibrationally excited ground electronic state. The origin of the emitting species of bR is discussed

Inventory control: fully resource usage in production cycle

The paper considers the model of controlling optional resource with limited lifetime which should be completely used for the production cycle. The demand for the resource is of random character: the demand flow is Poisson with an intensity that is inversely related to the enterprise's additional profit, the purchases are i.i.d. random variables. The authors use a diffusion approximation to the system. The mean, the variance and the correlation function of the inventory level process are found. The optimization of the average additional profit is carried out in a case of linear dependence of the intensity of the profit; the optimal initial inventory level is also found

Measurements of urea and glucose in aqueous solutions with dual-beam near-infrared Fourier-transform spectroscopy

This study investigates the use of a dual-beam, optical null, FT-IR spectrometer to measure trace organic components in aqueous solutions in the combination band region 5000-4000 cm(-1). The spectrometer may be used for both single- and dual-beam measurements, thereby facilitating comparison of these two modes of operation. The concentrations of aqueous solutions of urea and glucose in the ranges 0-40 mg/dL and 0-250 mg/dL, respectively, were determined by principal component regression using both modes. The dual-beam technique eliminated instrumental variations present in the single-beam measurements that must be taken into account when quantifying trace components from single-beam spectra. The data obtained with the dual-beam technique resulted in more stable calibration models based on principal component regression. These calibration models need fewer factors and yield lower prediction errors than those based on traditional single-beam data
