Synthesis of Ni/NiO Nanopowder by Thermal Decomposition of Nickel Acetate Amine

Ni/NiO nanopowders have been synthesized using thermal decomposition of nickel acetate hexaammine in air. Obtained powders have been characterized by IR-spectroscopy, XRD and TG, DTA, DTG and HR TEM. Thermal decomposition of nickel ammine complexes occurs with forming nickel hydroxide, carbonate and hydroxocarbonate ammines precursors. Mean particle size of nickel and nickel oxide phases in powders depends on temperature. In the temperature range from 350 to 500 degrees Celsius the particle size of nickel oxide has grown from 5 to 25 nm and nickel from 50 to 55 nm. Particle size of 5 nm for nickel hydroxide ammine remained unchanged with temperature. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3481

Study of dose-dependent effect of 2-ethyl-6-methyl-3 hydroxypyridine succinate on the contractile function of isolated rat heat

In experiments on the isolated rat heart there were studied the effects of different doses (21.43 mg/kg/day and 85 . 72 mg/kg/day) 2-ethyl-6-methyl-3 hydroxypy ridine succinate ("EkoPharmInvest", Russia), on the contractile function of isolated hearts subjected to prior doxorubicin model (20 mg/kg, intraperitoneal) of pathology. The dynamic of the power mechanisms of ion transport was evaluated by imposing high h eart rate (480 BPM) and increase concentration of Са2+ to 5 mmol in perfusat

Evaluation of cardioprotective effects of the incritinmimetics exenatideand vildagliptin in the experiment

The results of experimental and clinical trials make it clear that incretin mimetics possess pleiotropic effects and demonstrate the value in terms of assessment of their potential opportunities as cardioprotectors. Goals: To study the cardioprotective effects of exenatide and vildagliptin on the model of doxorubicin-induced cardiomyopath

Experimental approaches to the assessment of potential cardioprotective means with doxorubicin-associated cardiomyopathy

Development of methodological approaches for evaluation of cardioprotective activity of drugs in doxorubicin cardiomyopath

Etiquette Behavior in the Context of University Organizational Culture

The aim of this study is to reveal interrelationship between the notions of etiquette behavior of students and teachers and the characteristics of organizational culture at universities. Methods. The research is based on a survey. The sample included 141 students and 69 teachers from Russian universities. A set of diagnostic methods was used to gather the empirical data. Data on teachers’ and students’ attitude to institutionalization of etiquette rules and dress code as well as students’ compliance with etiquette rules were collected using the author’s questionnaire; data on evaluation of etiquette functions were obtained through the questionnaire Subjective Evaluation of Etiquette Functions’ Significance by O.I. Danilenko, data on existing and preferred organizational culture in the respondents’ universities – through Organizational Culture Assessment Instrument (OCAI) by K. Cameron and R. Quinn. Results. Correlations between indicators, characterizing etiquette behavior and current organizational culture type, were identified in both groups: positive for clan and adhocracy culture type, negative – for hierarchical. Statistically significant positive correlations between evaluation of etiquette functions' significance and evaluation of students’ compliance with etiquette rules and clan culture, negative correlations between the same indicators of etiquette behavior and hierarchical culture were revealed in the students’ group. In teachers’ group, evaluation of etiquette functions' significance, positive attitude to institutionalization of etiquette rules and dress code are correlated positively with clan and adhocracy organizational culture, negatively – with hierarchical. Conclusion. The gathered data indicate: the higher both students and teachers evaluate characteristics of clan and adhocracy culture, the higher is their evaluation of the importance of etiquette behavior. The higher are values of hierarchical culture characteristics, the lower is evaluation of etiquette importance
