Plastic is produced from the byproduct of gasoline products, which possesses a higher possibility of recycling the waste plastic as an alternative fuel. Research conducted on plastic fuel shows that a diesel engine can run with 100% plastic oil. The present work is focused on the effect of distilled plastic oil on the cetane index as the cetane index is a major fuel property of diesel that affects the ignition quality and exhaust emissions of the engine. For the measurement of the cetane index, two standards are followed and they are ASTM D4737 and ASTM D976. It is found that Crude plastic oil produced from thermal pyrolysis of waste plastic possesses a wide variety of hydrocarbon i.e. lower to higher hydrocarbon. From the fractional distillation of crude plastic oil at three temperature ranges 200◦C, 290◦C and up to the final boiling point, it gave petrol grade oil and diesel grade oil (both low and high grade). Also, it was found that the recovery of distilled high-grade plastic oil is higher than other distilled crude plastic oil. Along with this, crude plastic oil, as well as high-grade plastic oil, have a higher cetane index than the diesel available in the market. Similarly, blending diesel with high-grade plastic oil up to 20% by volume and with low-grade plastic oil up to 10% by volume increases the cetane index of fuel.","PeriodicalId":263238,"journal":{"name":"Journal of Innovations in Engineering Education","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123482716","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}

On 2019, 28 Mt of E-waste generation was recorded in Nepal and its management has created a burden to the landfill sites. Also, marble dust is a waste obtained during processing and installation of marble which can be used as filler or fine aggregate in concrete for strength enhancement. Utilization of crushed E–waste plastics and waste marble dust in concrete will introduce a green and environment friendly method of construction without any compromise in the utility parameter and would represent positive effect to minimize the environmental degradation and replace naturally available aggregates which are continuously been used. The strength effects of waste electronic plastics and waste marble dust as aggregate replacement in concrete was studied in this research. For this study, 12 sets of concrete mixes were prepared with constant water cement ratio of 0.55. Marble dust was used as a sand replacement at 2.5%,5%,7.5% and 10% by volume of sand. Further 2 sets of 4% and 6% replacement of sand by marble dust was prepared to find out the optimum value as 5% replacement showed greater compressive strength. E-wastes plastics were then used as replacement to coarse aggregate at 1%, 2%, 3%, 4% and 5% along with 5% replacement of sand by waste marble dust. The workability test, compressive strength and flexural test of the mixes were determined. Based on the study, result showed that the compressive strength at 5% replacement of sand by marble dust was maximum while E-waste plastics replaced up to 4% had compressive strength greater than that of nominal mix concrete of grade M20. Flexural strength also increased of concrete containing E-plastic than that of normal concrete.","PeriodicalId":263238,"journal":{"name":"Journal of Innovations in Engineering Education","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131800429","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}

In this article the essence of such definition as “collaboration”, some features of organization of collaborative learning environment in the integral pedagogical process of the university are considered. The efficiency of creation of collaborative educational environment for revealing potential possibilities and professional competences of future teachers is revealed. The main emphasis is made on the importance of the facilitator's position in the organization of students’ collaborative activities. The influence of collaborative environment on the success of future teachers is justified.In the age of rapid development of knowledge-intensive technologies and comprehensive expansion of the information space, there is an urgent need to develop the spiritual and moral qualities of the individual, because in the realities of modernity there is a separation and isolation of a person from society, a crisis of spiritual development, the problem of lack of humanity is raised acutely, there is an alienation of young people from national and cultural values.

Complex studies show that the chronic pathology of schoolchildren is at an extremely high level. Against the backdrop of social insecurity, the problem of alcoholization and drug addiction of children and adolescents is growing, which poses a threat of moral decay to young people. Children’s health is affected by a number of negative factors: a decline in the standard of living in the country as a whole, a widespread deterioration of the environmental situation, and negative changes in the financial situation and the educational potential of the family. Unfortunately, the share of guilt for the current situation today is assigned to the school, which does not meet the modern requirements of hygiene and natural sciences of age physiology, causes disruption of adaptation, chronic fatigue of children and provokes the growth of diseases. Educational potential of school is considerably reduced: “...educational practice stays in a condition of influence on it of casual reference points, elements of positive, and even more negative, influences and uncontrollability”. In these conditions, the problem of maintaining health and education for a healthy lifestyle in schoolchildren is of particular interest to researchers. In the process of upbringing of children of primary school age the role of significant others - teachers and parents - is great. However, for the effectiveness of education for a healthy lifestyle is not enough readiness of the teacher, as the categories of lifestyle, lifestyle is largely associated with the family, with the way of life, with traditions, with the way of life of parents. Parents act as a role model for younger students, so in the process of upbringing important factors are personal, purely individual characteristics of parents, which include health status, physical culture, and attitude to health, culture of communication, ethical culture and experience of a healthy lifestyle.","PeriodicalId":263238,"journal":{"name":"Journal of Innovations in Engineering Education","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116154417","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}
