Essence of the monitoring system for managing project life cycle at an instrument-making holding

The article examines the issues the monitoring system for managing project life cycle at an instrument-making holding project. The purpose of monitoring is to improve the project management system, identify discrepancies between actual and planned indicators, monitor the project indicators, change the organisation strategy development, proposals to eliminate potential threats. The main tasks adopted as monitoring-screening tools are the identification of key indicators; processing and aggregation of critically necessary information about specific project tasks; identification of external and internal risks; attractors that strongly influence the implementation of the project; issue of operational reports on the project; forecasting and decision-making, development of proposals to correct negative situations; ensuring the integration of the monitoring system in the information environment of the holding. The article reveals the key problems in this area and outlines conceptual directions for improving the process under study. The relevance of the material is the activity of a real specialist directly inside the dynamic structure of the holding, who knows all the old management methods and models new and redundant management methods, updating them in accordance with external and internal challenges. The experience of implementing the project of changing management paradigms during the crisis can be used to minimise further risks and accelerate the choice of effective management methods in organisations of large holdings, which, in turn, will allow you to reorient yourself as painlessly as possible to new management mechanisms that will contribute to more efficient operation of the holding as a whole

A green chemical method for synthesis of bromine-containing “building blocks” for the production of photovoltaic polymers

Bromine-containing derivatives of aromatic and heteroaromatic compounds are the most important "building blocks" in the assembly of modern Photovoltaic Polymers (PV). While PV is being developed to produce "green" energy, converting sunlight to electricity, the reactions for producing brominated derivatives of building blocks described in the literature are examples of obsolete and environmentally dirty technologies. More environmentally harmful than bromination with molecular bromine [1] can only be bromination by molecular bromine in a concentrated hydrobromic acid medium [2]. Using 1,1'-diphenyl (1), 9H-diphenylcarbazole (2) and thiophene (3) as examples, we successfully tested the bromination of the above objects with a mixture of potassium bromide and bromate in acetic acid as outlined in the diagram

Structural, Semantic and Linguocultural Parameters of Concept Sphere of FASHION INDUSTRY (Modern English Discourse)

This author’s development of the concept sphere model of FASHION INDUSTRY is presented in the article. Lexical units, nominations of objects, subjects and events of the fashion industry, as well as text fragments obtained from modern English-language artistic discourse, media and blogosphere are used as empirical material. The relevance of the study is due to the high rate of transformation of this conceptual field under the influence of a number of extralinguistic factors that make certain changes in the lexical composition of the language, the value dominants of society and the mechanisms of their verbalization. It is shown in the paper that the structure of the concept sphere is anthropocentric, as it is organized around the concept PARTICIPANTS. This concept is not only interconnected with other components of the FASHION INDUSTRY cognitive space — OBJECTS, EVENTS and PROPERTIES — but also determines their semantic content and linguistic and cultural specificity. Particular attention is paid to the actualization of the PROPERTIES component incorporated into other concepts.  Cognitive modeling of the structural and content parameters of the concept sphere made it possible to determine the most highlighted value dominants in the current discourse: innovation, comfort, universality, democracy, mediation with the transition to digital format, economic feasibility and environmental friendliness

A New Method for the Synthesis of Bromine-Containing Heterocyclic Compounds for Photovoltaic Polymers

With the development and improvement of systems for converting sunlight into electric and thermal energy, more and more work is emerging on the development of the newest and most promising direction in solar energy, namely the creation of solar cells based on photosensitive polymers. Recently the power conversion efficiency of organic photovoltaic (OPV) devices has overcome the barrier of 17%, and thus we can expect a new wave of scientific interest in the development of new, more efficient OPV devices. Unfortunately, during searching for highly efficient chemical structures of OPV polymers, the researchers missed an important point: all photovoltaic polymers consist of aromatic and heteroaromatic «building blocks», which, in turn, are synthesized based on outdated techniques using highly toxic, dangerous for life and environment precursors. The development of «green», environmentally friendly, economically viable methods for the synthesis of photovoltaic polymers and building blocks for their production, will make the energy obtained from OPV truly «green». In this work, we present an alternative, «green» method for synthesizing halogen-containing aromatic and heteroaromatic, expensive building blocks most commonly used in the synthesis of photovoltaic polymers, which can be used to obtain photovoltaic polymers of various structures. We present the original methods for the synthesis of 4,4-dibromo-1,1- biphenyl (1), 4,7-dibromo-2,1,3-benzothiadiazole (2), 2-bromothiophene (3) and 2,5-dibromothiophene (4). All these methods differ from the previously described routes by their simplicity and convenience of their implementation, the absence of corrosive and irritant reagents, good yield and compliance with the principles of «Green Chemistry»
