Also, an analyze of the variation of the total energy of the plate, kinetic energy of the bullet and bullet velocity over time are presented.","PeriodicalId":326593,"journal":{"name":"SCIENTIFIC RESEARCH AND EDUCATION IN THE AIR FORCE","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126429666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The number of micro ecosystems in which hierarchy and power-centered forms of organization prevail is undoubtedly large, given the fact that authoritarian regimes have been mostly abolished and invalidated during relatively recent history, and many people are still unconsciously reminiscing on their unwritten rules of conduct. This paper intends to take a closer look into the impact that various power distance index values have on organizational culture, with multinationals being the niche thoroughly studied. By analyzing official performance reports in correlation with dr. Geert Hofstede’s premises, the author intends to give insight into how overall worker performance is affected by autocracy, inequality, and responsibility centralization, which are all consequences of high-power distance indexes.","PeriodicalId":326593,"journal":{"name":"SCIENTIFIC RESEARCH AND EDUCATION IN THE AIR FORCE","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133216834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UHI is most noticeable during the summer and winter. The main cause of the UHI effect is from the modification of land surfaces. In this research was using MODIS and SENTINEL data.

It was carried out within a project financed by the Scholarship Scheme for Universities, concluded between the Ministry of National Education through the Management Unit of Externally Funded Projects and the Faculty of Electrical Engineering, Energy and Applied Informatics, “Gheorghe Asachi” Technical University of Iasi. The specific objectives of the project pursued three intervention components: motivation (M), networking (R) and workload (V). These have been directly correlated with other identified aspects (individual failure, academic failure) that lead to school dropouts and low academic performance. In order to achieve the objectives, the project presented a proposed activity plan for a target group of 80 students for one year of implementation). The activities proposed within the project represent punctual educational interventions on the factors that influence school dropout and academic performance. The evaluated program, the results of which we present here, was subordinated to the objectives related to the motivation of the students and their relationship skills and pursued personal development through creativity and socio-emotional education in students. This dimension of the programme was chosen because a major need existing on the labour market is the need to educate young people to have the attitude of a winner and to find solutions to problems .The behavioural acquisitions of the students, within the personal development programme through creativity and social-emotional education were: flexible, generative thinking in solving problems; acquiring coping strategies; optimisation of personal and academic life.","PeriodicalId":326593,"journal":{"name":"SCIENTIFIC RESEARCH AND EDUCATION IN THE AIR FORCE","volume":"1641 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116505828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
