Leadership in our life

In the modern world, the theme of leadership takes an honorable place and is of great interest. Now most employers in each vacancy require you to have leadership and organizational skills. Managers see this as a sort of panacea and try to become leaders as much as possible. This again, in turn, confirms the high demand for the leaders. John Quincy Adams, 6th US President, said: “If your actions inspire others to dream more, learn more, do more and become more, you are a leader” [1]

PROFESSIONALLY ORIENTED EXTENSIVE READING AS A TYPE OF IT STUDENTS’ INDEPENDENT WORK

The present work aims to analyse and describe ways of integrating extensive reading into the high educational process. The article proves the necessity of providing the independent work of students who study Information Technologies in tertiary education as it is a vital and motivating way for students to accumulate professional information, acquire new knowledge, gain valuable experience, and upgrade 21st-century skills. To meet the demands of the global labour market, IT students need to understand documentation and scientific literature. They should be ready to participate in conferences, webinars, masterclasses or meetings, to collaborate and communicate in a team via speaking English as it is the most widespread language in the professional environment. Since IT students are fascinated by their speciality, we suggest reading professional literature as one of the ways of obtaining information and increasing the level of professional competence. The article shows the advantages of extensive reading of professional literature and offers examples of websites with level and content-appropriate texts. The authors confirm the positive and beneficial results of extensive reading as part of IT students` independent work

Diurnal dynamics of the Umov kinetic energy density vector in the atmospheric boundary layer from minisodar measurements

The diurnal hourly dynamics of the kinetic energy flux density vector, called the Umov vector, and the mean and turbulent components of the kinetic energy are estimated from minisodar measurements of wind vector components and their variances in the lower 200 m layer of the atmosphere. During a 24 h period of continuous minisodar observations, it was established that the mean kinetic energy density dominated in the surface atmospheric layer at altitudes below ~50 m. At altitudes from 50 to 100 m, the relative contributions of the mean and turbulent wind kinetic energy densities depended on the time of the day and the sounding altitude. At altitudes below 100 m, the contribution of the turbulent kinetic energy component is small, and the ratio of the turbulent to mean wind kinetic energy components was in the range 0.01–10. At altitudes above 100 m, the turbulent kinetic energy density sharply increased, and the ratio reached its maximum equal to 100–1000 at altitudes of 150–200 m. A particular importance of the direction and magnitude of the wind effect, that is, of the direction and magnitude of the Umov vector at different altitudes was established. The diurnal behavior of the Umov vector depended both on the time of the day and the sounding altitude. Three layers were clearly distinguished: a near-surface layer at altitudes of 5–15 m, an intermediate layer at altitudes from 15 m to 150 m, and the layer of enhanced turbulence above. The feasibility is illustrated of detecting times and altitudes of maximal and minimal wing kinetic energy flux densities, that is, time periods and altitude ranges most and least favorable for flights of unmanned aerial vehicles. The proposed novel method of determining the spatiotemporal dynamics of the Umov vector from minisodar measurements can also be used to estimate the effect of wind on high-rise buildings and the energy potential of wind turbines

Physicochemical properties of blue fluorescent protein determined via molecular dynamics simulation

Blue fluorescent protein (BFP) is a mutant of green fluorescent protein (GFP), where the chromophore has been modified to shift the emitted fluorescence into the blue spectral region. In this study, MD calculations were performed with the GROMACS simulation package and AMBER force field to investigate the dependence of BFPs physicochemical properties on temperature and applied pressure. The MD approach enabled us to calculate the compressibility of protein itself, separately from the nontrivial contribution of the hydration shell, which is difficult to achieve experimentally. The computed compressibility of BFP (3.94 ×10 −5 MPa −1 ) is in agreement with experimental values of globular proteins. The center-of-mass diffusion coefficient of BFP and its dependence on temperature and pressure, which plays an important role in its application as a probe for intracellular liquid viscosity measurement, was calculated and found to be in good agreement with photobleaching recovery experimental data. We have shown that decreased temperature as well as applied pressure increases the water viscosity, but the concomitant decrease of the BFP diffusion coefficient behaves differently from Stokes-Einstein formula. It is shown that the number of hydrogen bonds around the protein grows with pressure, which explains the aforementioned deviation. Pressure also reduces root mean square (RMS) fluctuations, especially those of the most flexible residues situated in the loops. The analysis of the RMS fluctuations of the backbone C Α atoms also reveals that the most rigid part of BFP is the center of the Β-barrel, in accord with temperature B factors obtained from the Protein Data Bank. © 2008 Wiley Periodicals, Inc.

Influence of the outer scales of temperature and dynamic turbulence on the characteristics of transmitted acoustic radiation

In the present work, the problem of propagation of monochromatic acoustic radiation in the lower 500-meter layer of the plain stratified moving turbulent atmosphere is solved by the Monte Carlo method. The influence of the parameters of models of the outer scales of temperature and dynamic turbulence on the intensity of transmitted acoustic radiation intensity is investigate
