«Representation of capillary phenomena from the physical model of unpacking a liquid»

Download an article

Based on the physical model of «unpacking» a fluid, published in 1983 to explain the physical nature of surface tension, an explanation of capillary phenomena was proposed. The unified physical nature of the condensation process and the processes in the capillaries expressed in terms of the surface tension of the liquid is proved. To prove the applicability of the «unpacking» model for capillary phenomena, an empirical Borelli-Jurin formula for determining the height of fluid lifting in capillaries was theoretically derived depending on the magnitude of the surface tension. The assumptions under which the formula is obtained are indicated. In addition, the article proposes a new formula for determining the maximum height of liquid lift in the capillaries, depending on the critical temperature of the liquid and the molecular weight of the liquid.

Download an article

The article discusses the method of evaluation of employee engagement in terms of a nonparametric estimate of the object. Methods for assessing the involvement of Q12 (Gallup) and Scriptunova E.A. were studied, which are difficult to consider universal and apply to all organizations without distinction. Therefore, to assess the personnel of the units in each organization, its own specific methodology for assessing engagement is needed.

«Correlation of temperatures of melting and boiling of substances from the hypotheses of unpacking the substance»

Download an article

According to the properties of melting points and boiling points of the elements of the periodic table of D.I. Mendeleyev the application of the unpacking hypothesis of the substance was verified. The article contains the results of the verification. In general, according to the data for 98 substances taken from the information in Internet, convergence of results with an error of up to 40% for 73 substances was obtained. The effect of periodicity on the result is found. An exception to the calculated dependences was obtained for ten substances: noble gas and most halogens. A large discrepancy between the theoretical formulas and the reference data was also caused by the 14 elements of the middle groups.

«Impact of Foreign direct investment on Export: Case of Armenia»

Download an article

According to the authors, foreign direct investments have a significant role in the economic development of each country. The analysis revealed that 34.3% change in export growth in Armenia and 13.7% in the world is conducted by FDI growth. This fact shows that Armenian export is more related to the FDI changes. Therefore, unlike global data, FDI growth in RA leads to decrease of export growth. This should be a signal for RA Government to implement a more effective policy for attracting foreign investments, leading the investors to the sectors, which have a comparative or competitive advantages in the foreign market.
