PROBLEMS OF ECOLOGICAL TOURISM DEVELOPMENT IN UKRAINE
We can also see the lack of established and working mechanisms that would ensure a constant connection between the owner of the farmstead, who is interested in selling their services and a client who wants to relax in one of the Ukrainian villages. The media pay little attention to this problem, which greatly complicates the process of perception and assimilation of information, on the one hand – potential tourists, on the other – the owners. It should also be noted that a single farm can not independently form and sell good tourist product. Creating an eco-tourism product requires the efforts of many people and people from many industries, who share a common goal
Investments in new technologies for import substitution of agricultural products
© International Economic Society.The article reflects new approaches to attract investment resources for the development of the poultry industry using innovative technologies. The proposed scientific recommendations will contribute to a significant reduction in the cost of hatching eggs in the first stage, and ultimately the overall cost reduction of finished products - poultry. The investments within three years will pay off. Thus this will create a new production base which is not inferior to the existing Western counterparts on the production and sale of hatching eggs as in the Mari El Republic and abroad, which will also help reducing the cost of the final product
Near-threshold production of -mesons in and NN collisions and -mixing
We consider near-threshold -meson production in and
collisions. An effective Lagrangian approach with one-pion exchange is applied
to analyze different contributions to the cross section for different isospin
channels. The Reggeon exchange mechanism is also evaluated for comparison. The
results from reactions are used to calculate the contribution of the
meson to the cross sections and invariant mass distributions
of the reactions and . It is found that
the experimental observation of mesons in the reaction is much more promising than the observation of mesons in
the reaction . Effects of isospin violation in the reactions
, , and , which are induced by -- mixing, are also analyzed.Comment: 43 pages, including 16 eps figures, to be bublished in Phys. Atom.

The country's economic growth models and the potential for budgetary, monetary and private financing of gross domestic product growth
This article examines the financing of GDP growth within the framework of catch-up, evolutionary and dynamic models of economic development. Methods/statistical analysis: using the principles of the Solow model and the Cobb-Douglas function, an analysis of the nature of the models has been carried out, considering the processes of capital accumulation, the rate of growth of the workforce, and various aggregate factor productivities. With the help of historical logic and statistical evaluation, examples of countries relating to each of the models examined are reviewed.
Based on the analysis, the main ways of financing economic growth are noted: both the state ones, due to budgetary and monetary policy measures, and private ones. It has been proven that with the transition from catch-up to an evolutionary or dynamic model, the role of the state as a centralizing force is diminishing. At the same time, the specificity of a dynamic model is due to the country's objective ability to be among the technological leaders, which is predetermined by the high values of current GDP, per capita GDP, and population size. Countries with an evolutionary model of development are constrained in their ability to maintain a comparable pace of development only within separate "growth points".
The main result of the work is the assessment of Russia's potential from the viewpoint of one of the models considered, based on a comparative analysis of several capital indicators, as well as a logical analysis of data on the level of GDP and population with other countries. This makes it possible to make recommendations for financing the country's GDP growth in the medium to long term. Scope/Improvements: The findings can be used in the development of Russia's financial and economic strategy up to 2030.peer-reviewe
The effect of water dynamics on conformation changes of albumin in pre-denaturation state:photon correlation spectroscopy and simulation
Water is essential for protein three-dimensional structure, conformational dynamics, and activity. Human serum albumin (HSA) is one of major blood plasma proteins, and its functioning is fundamentally determined by the dynamics of surrounding water. The goal of this study is to link the conformational dynamics of albumin to the thermal motions in water taking place in the physiological temperature range. We report the results of photon correlation spectroscopy and molecular dynamics simulations of HSA in aqueous solution. The experimental data processing produced the temperature dependence of the HSA hydrodynamic radius and its zeta potential. Molecular dynamics reproduced the results of experiments and revealed changes in the secondary structure caused by the destruction of hydrogen bonds in the macromolecule's globule
Aspects of a0-f0 mixing in the reaction pn->da0
Some aspects of a0-f0 mixing effects in the reaction
with perpendicular polarized proton beam are discussed. An angular--asymmetry
parameter is defined to study those effects. It is shown that, for energies
close to the production threshold, the angular--asymmetry parameter is proportional to the a0-f0 mixing amplitude for arbitrary polar and
azimuthal angles and of the outgoing meson. This
statement is also valid for arbitrary energies, but then only at polar angles
and . The mass dependence of the differential cross
section in the reaction in the
presence of \mix mixing is also discussed.Comment: 17 pages, 3 Figure

The roles of vitamin D in the prevention and the therapy of male infertility
The results of fundamental and clinical studies show the importance of providing males with vitamin D in order to (1) assist the formation of the testicles, (2) maintain the steroid-synthesizing and other functions of the testicles, (3) maintain the functioning of the spermatozoa and, in general, maintain the male fertility
Predictors of visceral obesity in normal weight obstructive sleep apnea patients
BACKGROUND: Obstructive sleep apnea syndrome (OSAS) is epidemiologically related to adverse cardiovascular outcomes. The pathophysiology clues are metabolic changes and obesity. The most studied anthropometric predictors of obesity, such as body mass index (BMI), waist circumference (WC), are influenced by various factors such as sex, type of constitution, hydration balance. The normal range of BMI and WC limits the diagnostic search for metabolic disturbances and visceral obesity in patients with respiratory sleep distress and can lead to increased cardiovascular risks. AIMS: to investigate the visceral obesity predictors in normal weight patients with obstructive sleep apnea syndrome. MATERIALS AND METHODS: We had performed а cross-sectional study, 68 patients were examined with mean age of 38.24 ± 7.4 years. The main group (38 individuals) was represented by patients with OSAS. The control group consisted of healthy individuals without OSAS. Alternative markers of visceral obesity, such as lipid accumulation products, visceral obesity index, conicity index have been studied. RESULTS: In the main group we found different disorders of lipid metabolism such as the increase in triglyceride levels by 94%, low-density lipids by 32%, total cholesterol by 10% compared with the control group. Anthropometric evidence was obtained for excessive fat accumulation in patients with normal body weight and OSAS: WC was 89.6 ± 5.7 cm in the main group and was higher than in the control group 83.7 ± 6.3 cm (p = 0.024) due to an increase in the visceral fat compartment, as evidenced by the conicity index (67.2 ± 7.0 and 59.3 ± 6.2 respectively, p = 0.032) and waist to height ratio (0.58 ± 0.05 and 0.53 ± 0.04 in the main and control groups, respectively, p = 0.041). Correlation relationships between the severity of sleep apnea syndrome and visceral obesity indicators were revealed. CONCLUSIONS: Normal weight patients with breathing disorders are at risk of visceral fat obesity and, thereby, increased cardiovascular risk. Assessment of additional markers of visceral obesity in patients with normal body weight and sleep apnea is recommended to include in the dynamic observation programms
