Lithium-6 from Solar Flares

By introducing a hitherto ignored Li-6 producing process, due to accelerated He-3 reactions with He-4, we show that accelerated particle interactions in solar flares produce much more Li-6 than Li-7. By normalizing our calculations to gamma-ray data we demonstrate that the Li-6 produced in solar flares, combined with photospheric Li-7, can account for the recently determined solar wind lithium isotopic ratio, obtained from measurements in lunar soil, provided that the bulk of the flare produced lithium is evacuated by the solar wind. Further research in this area could provide unique information on a variety of problems, including solar atmospheric transport and mixing, solar convection and the lithium depletion issue, and solar wind and solar particle acceleration.Comment: latex 9 pages, 2 figures, ApJ Letters in pres

SELECTION OF INVESTMENT PROJECTS IMPLEMENTATION OPTIONS

The main unresolved issues of choosing the most effective investment projects aimed at introducing innovative technologies have been considered. The traditional indicators of investment efficiency have been analysed. The expediency of using the indicator of the total reduced costs necessary for the implementation of the project has been substantiated. Attention has been paid to the possibilities of public-private partnership in innovation projects. The issues of shares distribution between participants in innovation and investment projects and the use of such objects have been reviewed. The current situation in the investment and construction sector of the economy has been assessed and ways to solve the main problems of investment activity in the construction industry have been outlined. The expediency of creating a mechanism for economic justification of the investment project implementation process, including the creation of reserve funds, has been substantiated. Recommendations for using the indicator of the of the investor’s total stated costs have been given

Investment attractiveness of the real sector of the economy in the framework of sustainable development

The article discusses the main problems associated with the development and implementation of investment projects at enterprises of the real sector of the economy for sustainable development. The current situation in the investment and construction sector of the economy has been evaluated and the ways of solving the main problems of investment activity in the construction industry are outlined. The issues of formation mechanism of the investment attractiveness of industries and individual organizations, production and investment activities have been consistently considered. Traditional indicators and criteria of investment efficiency have been analysed. The expediency of using indicators of the return on capital or assets of the organization necessary for the implementation of the project has been substantiated. It has been noted that in the process of developing an organization’s sustainable development strategy, it is necessary to take into account its digital transformation, within the framework of the possibility of functioning in a single digital environment in order to increase competitiveness. The applying a comprehensive assessment of the effectiveness of attracting investments for the implementation of investment programs based on the selected criteria, taking into account their functioning in the digital environment, – has been recommended

Attractive instability of oppositely charged membranes induced by charge density fluctuations

We predict the conditions under which two oppositely charged membranes show a dynamic, attractive instability. Two layers with unequal charges of opposite sign can repel or be stable when in close proximity. However, dynamic charge density fluctuations can induce an attractive instability and thus facilitate fusion. We predict the dominant instability modes and timescales and show how these are controlled by the relative charge and membrane viscosities. These dynamic instabilities may be the precursors of membrane fusion in systems where artificial vesicles are engulfed by biological cells of opposite charge

VALUE MANAGEMENT OF CONSTRUCTION PRODUCTS

The issues of cost management from the point of view of substantiating the reduction in the cost of investment products in order to create reasoned conditions for the interest of investors in long-term investments have been considered. The main emphasis on the real economic sector has been made, since it is in this sector that budget revenues at all levels are generated and overall economic growth is ensured. The existing mechanism of cost management in the implementation of investment programs has been assessed. Attention to the main elements of the cost management mechanism in the investment and construction sector of the economy has been paid. Factors that determine the level of production expenses taking into account the specifics of construction products have been analysed. An attempt to justify multi-factor cost management has been made. Management functions by performers have been differentiated

THE ROLE OF INNOVATIONS IN RENEWAL OF FIXED CAPITAL OF ORGANIZATIONS

The paper investigates modern trends in the development of innovative systems in Russia. These trends are caused, on the one hand, by the lack of a clearly formulated concept of an innovation system, and, consequently, by the inability to determine the ways of its development, and by the active use of undeservedly forgotten program-target planning methods, on the other hand. A detailed analysis of various positions and statistical materials allowed us to prove that, contrary to the generally accepted opinion, the Russian model of public administration and financing of innovative activities has signs of cluster and state-corporate types. The article considers the existing approaches to the management of innovation and investment activities of organizations, which is aimed directly at reproduction processes, in particular, the reproduction of fixed capital. The authors substantiate the necessity of creating territorially grouped innovation systems, which is explained by the dependence of industries and sectors of the economy on each other on the technological principle and the need to create technological links between them to realize their potential advantages within the framework of the implementation and creation of innovative products

Current management of the stability of organizations of the investment and construction complex in crisis situations

The article сonsiders topical issues of managing the economic stability of organizations in a crisis. The authors substantiate the need to study regional trends as an integral part of the anticrisis program at the regional level. Early diagnosis of crisis phenomena in the economy proves that a sufficiently high level of socio-economic development does not yet ensure complete economic security and the ability to withstand the threats posed by the unbalanced structure of the economy. Based on this, the problems in the field of ensuring the stability of organizations in the conditions of crises have been analysed and generalized. The problems faced by enterprises and organizations of the investment and construction sector of the economy have been considered. In methodological terms, the authors propose to use a system of indicative analysis and regulation of production and economic activities of enterprises of the real sector of the economy, as an organizational tool for resolving crisis situations in the economy. The study justifies the necessity of the introduction of digital technologies, on the basis of which it is possible to quickly implement the tasks set and achieve the expected results. The authors emphasize that we need our own anticrisis programs that to help maintain the sustainable functioning of organizations in the conditions of crisis phenomena

Project financing in the investment and construction complex

The problems arising in organizations during the process of investment activities have been considered. The results of financing and implementation of projects and programs have been analysed and interpreted consistently. The issues of expediency of using the profitability indicators of the capital or assets of the company, which requires for the project implementation, have been touched upon. Approaches to the possibility of using the project financing mechanism, have been substantiated. Attention has been paid to the positive and negative aspects of the application of project financing for the company investment activities. It has been noted that project financing is usually used in the implementation of large investment projects, which combine the economic interests of the state and private investors. Particular attention has been paid to the issues of project and program management within the digital environment in order to provide a unified information base. The analysis of possible risks when using the project financing mechanism has been provided and the approaches to influencing the emerging risks have been defined. The result of the study was the formation of factors affecting the effectiveness of the project financing mechanism in the implementation of investment projects and programs

Effect of an electric field on nucleation and growth of crystals

The effect of the electric field strength on nucleation and growth of the crystals of ammonium halides and alkali metal sulfates has been studied. The optimal electric field strength for NH[4]Cl and NH[4]Br crystals was found to be 15 kV/cm, and for NH[4]I, it equaled 10 kV/cm. No effect of the electric field strength on the crystal growth was found for alkali metal sulfates. This difference is analyzed in terms of the crystal growth thermodynamics. In case, when the electric field is small and the Gibbs energy is of a significant value, the influence of the electric field at the crystal growth is negligible. A method to estimate the critical radius of homogeneous nucleation of the crystal is suggested
