Китай как центр силы в современном политическом процессе
The main aim of the article is to scrutinize the importance of China’s center of power within the framework of social and political changes of the contemporary world. The following methods of research were used: theoretical, historical, economic and statistical analyses, comparative, structure-functional and factorial methods. It is stated that China’s economic and military build-up is a factor of social and political changes in the international arena. Among the factors affecting political and economic changes in the political system of the PRC as the article notes are the influence of traditionalism and soft power. The authors ar-rived at several conclusions. (1) Confucian values, inherent in China’s management culture, involve ideological influence over the Chinese form of government, which is connected with the CPC dictatorship. (2) The article reveals the growing influence of China on global eco-nomic and political processes. (3) The present-day political process implies the Chinese po-litical leadership (the political leadership of China)
Observation of polarization quantum noise of laser radiation in Rb vapor cell
We present experimental study of polarization quantum noise of laser
radiation passed through optically think vapor of Rb87. We observe a step-like
noise spectrum. We discuss various factor which may result in such noise
spectrum and prevent observation of squeezing of quantum fluctuations predicted

Temperature dependence of the electron spin g factor in GaAs
The temperature dependence of the electron spin factor in GaAs is
investigated experimentally and theoretically. Experimentally, the factor
was measured using time-resolved Faraday rotation due to Larmor precession of
electron spins in the temperature range between 4.5 K and 190 K. The experiment
shows an almost linear increase of the value with the temperature. This
result is in good agreement with other measurements based on photoluminescence
quantum beats and time-resolved Kerr rotation up to room temperature. The
experimental data are described theoretically taking into account a diminishing
fundamental energy gap in GaAs due to lattice thermal dilatation and
nonparabolicity of the conduction band calculated using a five-level kp model.
At higher temperatures electrons populate higher Landau levels and the average
factor is obtained from a summation over many levels. A very good
description of the experimental data is obtained indicating that the observed
increase of the spin factor with the temperature is predominantly due to
band's nonparabolicity.Comment: 6 pages 4 figure
New Pedagogy for Using Internet-Based Teaching Tools in Physics Course
Acquiring the mathematical, conceptual, and problem-solving skills required
in university-level physics courses is hard work, and the average student often
lacks the knowledge and study skills they need to succeed in the introductory
courses. Here we propose a new pedagogical model and a straight-forwardly
reproducible set of internet-based testing tools. Our work to address some of
the most important student deficiencies is based on three fundamental
principles: balancing skill level and challenge, providing clear goals and
feedback at every stage, and allowing repetition without penalty. Our tools
include an Automated Mathematics Evaluation System (AMES), a Computerized
Homework Assignment Grading System (CHAGS), and a set of after-homework quizzes
and mini-practice exams (QUizzes Intended to Consolidate Knowledge, or QUICK).
We describe how these tools are incorporated into the course, and present some
preliminary results on their effectiveness.Comment: 7 pages, 2 figures, submitted to the Physics Teache

Investigation Of Technological Properties Of Powder Of Eggplants
The aim of the article is to study and to generalize technological properties of eggplant powder, produced by infrared drying at temperatures 50-60 ºС. The results of the conducted complex of studies reflect main technological and consumption properties of the received puree that plays an important role at creating new culinary products.So, for studying technological properties of food eggplant powder, there was considered the complex of base functional-technological properties of powder, produced by infrared drying.For finding optimal conditions of rehydration of eggplant powders, there was studied the influence of such technological factors as: swelling ability; liquid; powder ratio; influence of the solvent temperature on renovation; renovation duration; degree of comminution of powders.Main parameters that influence the renovation ability of dried eggplants are investigated and studied in the article. The results of the studies of technological properties of eggplant powders prove their high rehydration properties. It gives a possibility to use powders at producing different culinary products not only for enriching them with functional ingredients, but also for giving them new technological properties.Based on the obtained results, there was elaborated and presented the new technological scheme of using renewed powders in food compositions
Morpho-functional characterisation of protective mechanisms of neutrophils in the patients at the terminal stage of chronic kidney disease
Patients with chronic kidney disease (CKD) are a unique clinical “model” for studying the functions of immunocompetent cells under the conditions of severe endogenous intoxication, inflammation and immunosuppression. The aim of our study was to perform a comprehensive assessment of morphological and functional activity of neutrophils in patients at the terminal stage of chronic renal failure. We examined 49 patients (16 women, 33 men, 22 to 63 years old) with CKD 5 D (according to the K/DOQI classification, 2006), and 60 healthy individuals (controls). Leukoconcentrates of venous blood were used as biological samples for the study. The following functional properties of neutrophils were evaluated: the formation of extracellular networks (netosis, NETs) determined microscopically with Romanovsky-Giemsa staining during cell cultivation for 30 and 150 minutes; production of reactive oxygen species (ROS) using cytochemical method with nitro blue tetrazolium, apoptotic activity (luminescence microscopy after staining with a mixture of acridine orange/ethidium bromide), as well as absorption capacity in the reaction of phagocytosis. The tests were performed in spontaneous and stimulated versions. The ATCC 25923 S. aureus strain killed by heating was used as a stimulator. An increase in netosis parameters was revealed in 30-min (but not 150-min) cell cultures in both spontaneous and stimulated versions (p < 0.001), as well as apoptosis (p = 0.02). ROS production by neutrophils and their absorption activity did not significantly change. The parameters of netosis and apoptosis directly correlated with each other (rs = 0.34; p = 0.03), being also dependent on the level of azotemia (correlation coefficient for the indices of netosis and urea level was: rs = 0.41; p = 0.01; for apoptosis and urea, rs = 0.34; p = 0.02). A relationship was found between the level of apoptosis and ROS production by neutrophils (r s = -0.51; p = 0.03). These studies have shown that the cells from patients with terminal-stage CKD are prone for a suicidal program – apoptosis and netosis. Considering the increased netosis just upon shorter cultivation of leukocytes (30 minutes), it can be assumed that NADPH-independent mechanisms are primarily involved. The direct dependence of netosis and apoptosis parameters on the level of azotemia allows us to consider accumulation of endogenous intoxication products, in particular, oxidized proteins, in the patient’s body as one of the primary reasons for increasing the suicidal neutrophil program
