The reasons for the formation of varnish deposits of turbine oils are determined. It is shown that the performance of turbine oils is determined by methods of ASTM D7843 (MPC) and ASTM D6971 (RUL) can be assessed, the process of formation of varnish deposits, the level of antioxidant properties, antioxidant content of, amend, and extend the oil change, and to predict critical situation in the operation of turbine equipment. The mechanism of formation of varnish deposits in turbine oils is proposed.

Perceived Involvement

The purpose of this study was to assess practitioners’ perceived involvement and challenges they encountered in the process of curriculum development in Secondary schools of Amhara Sayintworeda. Mixed research design was employed to provide answer to the basic questions of this research. The sample consisted of 125 secondary school teachers, 3 school principals, 4 vice principals, and 1 supervisor. Proportional random sampling technique was used to select the sample teachers and comprehensive sampling technique was used to select the sample school principals, vice principals, and the supervisor. The data was collected through questionnaire and semi-structured interview. The collected data was analyzed using percentage, one sample t-test and thematic description. The findings indicated low practitioners’ perceived involvement in all the curriculum development phases other than curriculum implementation. Absence of financial and material incentives and practitioners’ lack of motivation were considered as the major inhibiting factors for practitioners’ involvement in the different phases of the curriculum development process. On the basis of the major findings, relevant recommendations are suggested in the paper.

Представлены результаты изучения исходного материала столовой моркови и свеклы разного эколого-географического происхождения по устойчивости к патогенной флоре. Для условий Дальнего Востока созданы высокопродуктивные, устойчивые к патогенам сорта и гибриды столовых корнеплодов.The article presents the results of the study of the source material of table carrots and beets of different ecological and geographical origin for resistance to diseases. Geniuses for breeding of high-productive variety samples of root crops with rather high resistance to diseases in the conditions of the South of the Russian Far East are revealed.

The downy mildew (peronosporosis) is the most dangerous and harmful cucumber disease in the Far-Eastern region. Its harmfulness is the highest during the period of flowering – fruiting, because it may completely ruin the cucumber plants both in open and protected ground. Use of cucumber sorts with effective genes that are resistant to the disease is the most efficient way to fight cucumber peronosporosis. In this connection the publication adduces the facts of study the sorts and hybrids of different ecological and geographical origin from the genetic resources collection of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) in comparison with three zoned sorts of DV NIISH selection – Mig, Khabar, Amurchonok. The aim of researches – to identify the sort samples cucumber according to the main economically valuable traits and also to the degree resistance of genetypes to the main disease of the culture in the region – downy mildew (peronosporosis), for allow to select the source material for the creation of sorts and hybrids, highly productive and resistant to biotic and abiotic stress environmental factors in the monsoon climate conditions of Khabarovsk region. The perspective genetypes having both the resistance to the diseases and productivity are not revealed as a result of the evaluation of the collection of cucumber samples according to their susceptibility by fungus diseases and productivity. Slavyanskiy (Belarus) is more resistant to peronosporosis, especially in 2016 year conditions, although it was inferior to the damage degree of disease to the zoned sorts – Mig, Khabar, Amurchonok. This perspective sample is planned to be used as a source of donors of the main economically valuable traits in a further selective work.

And Control

Healthcare workers have good perception towards infection prevention, but there has been a poor practice towards it. Therefore, the aim of this study was to explore barriers to practice of infection prevention and control practice in teaching hospitals in Amhara region. A phenomenological approach used to explore the lived experience of healthcare workers and management staffs towards infection prevention practice and control. The data was collected from ten in-depth interviews and 23 focus group discussion participants, by face to face interview using open ended interview performed in safe and quiet places. Data was managed using OpenCode software version 4.03 and contents were analyzed thematically. Totally ten different barriers were identified, such as availability of facilities, shortage of material supply, lack of maintenance of facilities and equipment, high patient flow, experience, emergency situation, healthcare worker behaviour and healthcare worker’s information about infection prevention, low awareness of patients and visitors and overflow of families and visitors to the hospital. For effective infection prevention practice implementation, barriers should be considered via identifying specific organizational, healthcare worker, patients and visitors as targets.
