Relevance. In the times of economic transformation on the way to the market relations, Ukraine needs highly qualified economists who have high qualification for working in both domestic and international economies. That is why currently one of the priorities of the vocational education system ... The article aim is to identify and characterize the features of determining the results of training of the future economists on the example of the state university in China. Methods: The research methods used during the study are: theoretical methods: analysis (to study the educational and professional program of the state Chinese University and determine the results of training of future Bachelors majoring in Business Economics in Chinese universities), comparison ... empirical methods: observational (direct observation of the educational process at a state university in the People’s Republic of China) – to determine the specific features of determining and studying the results of a professional training of Bachelors of Business Economics at a Chinese Results. The article outlines and describes the specific features of determination of the results of the training of future Bachelors majoring in Business Economics which have been given and analyzed on the example of the university in China. The structure of the professional competence of future Bachelors of Business Economics is considered in accordance with the educational and professional program of Chinese University... Conclusions. The conclusion is justified that the results of professional training of future Bachelors of Business Economics in Ukraine and Europe, as well as in China, are determined on the basis of the competence approach. The analysis of the educational and professional programs of universities in China allowed us to determine such competence groups in the professional competence as follows: general (integral) competencies, which mean possession of flexible («soft») skills; personal (subject) competencies ...

Abstract The construction of the low-pressure Nizhny Novgorod hydroelectric complex covered by the Strategy for the Development of Inland Water Transport of the Russian Federation for the period up to 2030 envisages a ship lock as part of the hydroelectric system to ensure ships passage. One of the options under consideration is a ship lock with a head power system, which uses short bypass water-circulating culvert for filling and emptying the chamber. At the same time, an important task is to select the optimal modes ensuring movement of the gates of the filling and emptying systems, in which the normative values of the hydrodynamic forces influencing the vessel in the chamber during the lock process would not be exceeded. The article describes the experience of performing laboratory hydraulic studies of the ship lock model and presents the results of determining the optimal modes of locks movement in the ship lock filling and emptying systems. The studies were carried out on a model located in the hydrotechnical laboratory named after Professor V.E. Timonov of the State University of Maritime and River Fleet named after Admiral S.O. Makarov. The article describes the experience of performing laboratory hydraulic studies of the ship lock model and presents the results of determining the optimal modes of gates movement in the ship lock filling and emptying systems. The studies were carried out on a model located in the hydrotechnical laboratory named after Professor V.E. Timonov of the State University of Maritime and River Fleet named after Admiral S.O. Makarov. The studies included three series of measurements taken at different speeds of gates movement. The speeds were assigned based on the following idea: the maximum hydrodynamic forces of one of the series were close to the permissible values, and of the other two – 30–50 % smaller and larger, respectively. The experimental results determined the optimal operating modes of the systems for filling and emptying the lock chamber. It is recommended to select of the optimal modes of gates movement in full-scale conditions on the newly built ship locks immediately after their construction.

A simple, rapid and sensitive spectrophotmetric method for trace determination of salbutamol (SAL) in aqueous solution and in pharmaceutical preparations is described. The method is based on the diazotization coupling reaction of the intended compound with 4-amino benzoic acid (ABA) in alkaline medium to form an intense orange, water soluble dye that is stable and shows maximum absorption at 410 nm. A graph of absorbance versus concentration indicates that Beer’s law is obeyed over the concentration range of 0.5-30 ppm, with a molar absorbtivity 3.76×104 L.mol-1 .cm-1 depending on the concentration of SAL. The optimum conditions and stability of the colored product have been investigated and the method was applied successfully to the determination of SAL in dosage forms.

A simple and accurate spectrophotometric method for the determination of Trifluoperazine HCl in pure and dosage forms was developed. The method is based on the reaction between Trifluoperazine HCl and p-chloroaniline in the presence of cerium ion as oxidizing agent which lead to the formation of violate color product that absorbed at a maximum wavelength 570nm while the blank solution was pink. Under the optimum conditions a linear relationship between the intensity and concentration of TRF in the range 4-50μg/ml was obtained . The molar absorptivity 3.74×103 L.mol-1.cm-1 , Limit of detection (2.21μg/ml), while limit of quantification was 7.39μg/ml. The proposed analytical method was compared with standard method using t-test and F-test , the obtained results shows there is no significant differences between proposed method and standard method. Based on that the proposed method can be used as an alternative method for the determination of TRF in pure and dosage forms.
