They contaminate the land, air, and aquatic bodies with oil spills during industrial operations, like as drilling and refining. This causes harmful gases to be released into the atmosphere. Poor agricultural yields and changes to the soil's geotechnical qualities are the most common outcomes of soil contamination, both of which have the potential to impair engineering construction projects. Geotechnical qualities of clay soil are examined as a result of this study. Engenni Ahoada L.G.A. in Rivers, Nigeria provided the clay soil. We collected soil samples that were purposely contaminated with crude oil in the following percentages: 0 percent, 2 percent, 4 percent, 6 percent, 8 percent and 10% to 14% of the total dry weight. The geotechnical parameters of the soil samples were determined by a series of laboratory soil tests. The results demonstrate an increase in LL, PL, and PI from 31%, 20%, and 11% at 0% contamination to 56%, 41%, and 11% at 14% contamination, respectively. From 2.48 to 1.33g/cm3 to 1.74g/cm3 at 0 percent contamination, SPGR, BD, and MDD fell to 1.14, 0.97g/cm3 and 1.35g/cm3 at 14% contamination. At 0% contamination, OMC was 15%; at 16% contamination, it was 16.5 percent. Thus, the geotechnical qualities of soil are substantially impacted by crude oil pollution.","PeriodicalId":374413,"journal":{"name":"Asian Journal of Science, Technology and Society","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124252968","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 Internet of Things will transform everyday objects into intelligent virtual ones in the future. As a result of the Internet of Things (IoT), we will be able to monitor and control everything in our environment from a single point. An examination of the history of the Internet of Things shows that the number of IoT devices has increased recently and is expected to increase dramatically in the coming years, indicating that the Internet of Things will interact with every aspect of our lives. Home automation and cloud-based industry applications are just two examples of IoT's wide range of applications. This paper looks back at some of the key moments in the history of the Internet of Things. In addition, a number of cutting-edge IoT applications are discussed in this article. In the future, this research will be helpful and useful in the field of IoT.","PeriodicalId":374413,"journal":{"name":"Asian Journal of Science, Technology and Society","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127774083","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}

Educational stakeholders had responded to this challenge admirably by using virtual learning and by enhancing their virtual learning environments in order to prevent interruptions to their students' studies (VLEs). As a result, the VLEs have specific requirements that must be fulfilled in order to support students' learning in a reliable and effective manner. Through a descriptive study, this research sought to critically examine the influencing elements of learning in VLEs. The results showed that characteristics connected to student motivation for learning in a VLE include teacher personality, student autonomy, ICT, and course design. These results are regarded as significant contributions for educational stakeholders to address the educational, psychological, social, and technological demands of students in VLEs that have partially or completely replaced traditional educational methods in most academic institutions across the world.","PeriodicalId":374413,"journal":{"name":"Asian Journal of Science, Technology and Society","volume":"203 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123310594","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 agricultural forestry, environmental factors play an important role. Agroforestry uses a variety of methods, including tree breeding and genetic exchange, to create new plant varieties. Agroforestry also plays an important role in the recycling of waste water through efficient treatment water plants. Agroforestry systems for cacao are critical to ensuring that the right number of pants can be grown for each variety. Cacao can help alleviate symptoms of depression, stress, high blood pressure, and heart disease if consumed in the correct amounts. Soils have the ability to replenish themselves at times, resulting in the growth of new trees. Growth can be stunted or even stunted completely in soils with poor drainage, too much water, or not enough water at all. There is no doubt that agroforestry methods such as the taungya system and silvopastoral system can help trees grow. By preserving sustainable development, we can use biofuels to power large industrial and commercial energy production facilities.","PeriodicalId":374413,"journal":{"name":"Asian Journal of Science, Technology and Society","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125421838","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}
