Investigation of Conditions and Benefits for Ukraine in the Transition of Its Household in the Rank of the Internal Investor of the State

In the article the place, role and functions of families (households) as economic subjects of the market system are clarified. The interrelation, interdependence of categories of "savings", "investments" and "consumption" is defined. The importance and location of the internal investor in the investment process at the macroeconomic level is proved. The algorithm for determining the level of aggregate income of a family necessary for transition to the rank of an internal investor of the state is presented. Parallels are drawn between the author\u27s theoretical and methodical approach proposed in the article and between the theories (laws, models) of a number of well-known economists, such as E. Engel, M. Tugan-Baranovsky, J. Keynes, P. Samuelson and others. The features of practical definition of the minimum level of the aggregate income of a family and a household for savings and investments for Ukrainian realities are revealed. The current and desired operating conditions and the results of financial and economic development of each of the interested parties are considered. In particular, for the population it is shown how, based on its real income, to identify and plan expenditures in order to move to investments. In addition, it is investigated: first, what exactly is the real minimum level of income per month will allow one person or a family (of two, three, four people) to survive in the economic conditions that defined public authorities and formed the market; secondly, what exactly need s a person or a household to be able to meet at an appropriate level of income; thirdly, what level of income will allow the population to save and convert these savings into investments (with their subsequent distribution for the development of domestic business and entrepreneurship). At the same time, it is shown how the state (on Ukrainian data) can influence the growth of domestic investment in order to reduce the deficit of financial resources for the development of business and the economy of the country

Spin distribution of nuclear levels using static path approximation with random-phase approximation

We present a thermal and quantum-mechanical treatment of nuclear rotation using the formalism of static path approximation (SPA) plus random-phase approximation (RPA). Naive perturbation theory fails because of the presence of zero-frequency modes due to dynamical symmetry breaking. Such modes lead to infrared divergences. We show that composite zero-frequency excitations are properly treated within the collective coordinate method. The resulting perturbation theory is free from infrared divergences. Without the assumption of individual random spin vectors, we derive microscopically the spin distribution of the level density. The moment of inertia is thereby related to the spin-cutoff parameter in the usual way. Explicit calculations are performed for 56^Fe; various thermal properties are discussed. In particular, we demonstrate that the increase of the moment of inertia with increasing temperature is correlated with the suppression of pairing correlations.Comment: 12 pages, 8 figures, accepted for publication in Physical Review

Start to End Beam Dynamic Simulations for Femto Science Factory Feasibility Study

Design studies for a future multi turn ERL based light source at HZB are being investigated. The Femto Science Factory will provide its users with ultra bright photons of angstrom wavelength at 6 GeV. The FSF is intended to be a multi user facility and offer a wide variety of operation modes. A low emittance 0.1 mrad mode will operate in conjunction with a short pulse 10 fs mode. This paper reports on the first results of the start to end beam dynamic simulations for both modes. Higher order geometric and chromatic aberration terms have been suppressed using both multipole magnets and biased off crest acceleration. The influence of the collective effects coherent synchrotron radiation on the transversal emittance is minimised by adjusting the horizontal phase advanc

Feasibility Study of Multi Turn ERL Based Synchrotron Light Facility

Energy Recovery Linacs ERL have been discussed as drivers for synchrotron radiation facilities in X ray region for over a decade. The first proposal for a multi turn ERL as a next generation synchrotron light facility was in 1997. Since then great advances in ERL technology and high brightness electron source development were achieved, ERL based high power free electron infrared laser at JLab and the demonstration of multi turn energy recovery at BINP. The feasibility of an X ray ERL based light source seems more and more realistic. An overview of the design of a multi turn ERL under development at Helmholtz Zentrum Berlin FSF Femto Science Factory is given in this pape
