Students with disabilities are among the groups that are underrepresented in STEM careers worldwide. The problem is of great concern as persons with disabilities are rarely found in stem career fields. This study investigated whether and to what extent the selected factors predict STEM career interest in students with disabilities in senior secondary schools in Nigeria. A quantitative approach was utilized in the study, using descriptive research design. Data were collected using a demographic questionnaire, three subscales were of the interest in STEM career questionnaire developed by Halim et al., (2018), and stem Career Interest Survey (STEM-CIS) (Kier et al., 2014). Data analyses were conducted using descriptive statistic and regression analyses. Descriptive statistics showed that participants recorded high score in social influences on STEM career interests (Mean= 3.42, SD=.69) and poor perception of STEM career (Mean=2.45, SD=.72)among students with disabilities. Regression analysis showed that interest in STEM career fields, such as science, technology, engineering and mathematics related careers were predicted by social influences, perception of STEM career and STEM self-efficacy in the participants. It was concluded that social influences, perception of STEM careers and STEM self-efficacy were the major determinants of STEM career interests in students with disabilities. These findings can be used to inform career counseling and research.","PeriodicalId":14009,"journal":{"name":"International Journal of Mechanical and Production Engineering Research and Development","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72787120","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}

These oils in soil or water currents, such as sewage, can harm the environment. Groundwater and soil may become polluted by this. Lubricant costs are lowered by recycling these pollutants into useful products. This is a creative way of treating waste and will have a huge effect on the environment as well. This will decrease air/water contamination and fresh raw materials as well and greenhouse gas emissions will be minimized by recycling. Refining therefore restores the substantial and chemical properties of lubricating oil, which is capable of reverting to the original and intended usage of the oil used for the production of mixed essential oils in lubricants, minimizing the use of virgin oils. To return to its original intended use, recycling reproduces the physical and chemical properties of lubricants. This article explores the refining of lubricating oil using the solvent process and vacuum distillation, by oil recycling technology. Using three types of solvents: 1-propanol, n-butanol, and ethanol, the laboratory experiment was based on a complete global design. The purpose of this document was to recycle engine oil and recover valuable products. Impurities were isolated by filtration and separation, then to recover useful products by solvent extraction. We measured the specific gravity, density, viscosity, flash point, fire point, pour point, sulphate ash content, total base quantity, colour, residue of carbon, water content and compared the original oil. The kinematic and dynamic viscosity of recovered oil was found to be greater by different separation methods at lower temperatures.","PeriodicalId":14009,"journal":{"name":"International Journal of Mechanical and Production Engineering Research and Development","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87515720","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 two heaters were operated together under the same conditions and at a constant air flow 0.0416 kg/s. The results showed that the thermal efficiency and air temperature exiting from the solar heater can be improved using the improvements that have been indicated. As the average thermal efficiency was 66.78% for the improved heater and 30.35% for the conventional heater in the month of March 2020. The results also showed that the improved heater retains the heat gained from solar intensity for a longer period compared to the conventional heater at a constant solar radiation intensity. These improvements also contributed to a clear increase in the temperature of the air exiting the system. The maximum difference in the temperature of the air entering and leaving the heaters in February 2020 reached 28.75°C, and 16.75°C for the improved and conventional heaters, respectively. The results also proved that the improvements over the conventional system led to a reduction in the amount of heat lost from the solar heater.","PeriodicalId":14009,"journal":{"name":"International Journal of Mechanical and Production Engineering Research and Development","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85360650","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}
