These new approaches may have varying effects on ester quality. Thus an investigation is necessary to determine cost saving measures that do not compromise ester quality. This work examined the effects of a cost saving strategy on Biodiesel quality. This conservative method involved the transesterification of a Jathropha-Moringa oil blend using a blend of two primary alcohols. Three alkaline catalysts were also used. The reaction conditions were: Jathropha to Moringa oil blending ratio of 4:1; Methanol to ethanol blending ratio of 4:1; Alkaline catalyst concentration of 0.5 w/w %; reaction time of 40 minutes; stirring speed of 1000 rpm; Temperature of 60°C and an Alcohol to oil molar ratio of 7.5. Biodiesel samples were tested according to ASTM D6751 and AOCS guidelines. Results indicated that the density, iodine values, flash point and fire points of esters did not vary significantly as the experiment was repeated using three different alkaline catalysts. It also showed that the effect of NaOH, KOH and CaO were not always negative when they were significant. Lastly, the methods applied in this did not compromise ester quality with regard to observed fuel parameters.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"174 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91064177","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 COVID-19 pandemic was a tipping point for many sectors that boost economies worldwide, mainly to mining sector.

The resulting materials were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), transmission electron microscope (TEM) and particle size distribution analysis using dynamic light scattering technique (DLS). The results showed that the TEM images exhibited more separate individual carbon bundles with particle size around of 396 nm after enzyme immobilization rather than the spaghetti-like tubes with size about 180 nm in the case of ox-MWCNTs. Also, the lowering in the zeta potential negative value (-5 mv) proved that the free carboxyl groups at ox-MWCNT surface were decreased after enzyme immobilization. Moreover, the thermal stability was decreased after enzyme immobilization using TGA. These results confirmed that the laccase could be reacted at the side walls of the ox-MWCNTs without structure damage. The biocatalytic effect of the immobilized laccase was investigated after its incubation with silver nitrate solution for 1 and 24 h. It can be concluded that the biocatalytic efficiency of the immobilized laccase could be enhanced after its incubation with silver nitrate solution for 24 h at room temperature relative to the free form. On the other hand, the enzyme stability was improved after immobilization up to 50ºC and at pH 3.0, while no remarkable differences on the activity values were observed for immobilized and free laccases at acidic pH range (4-6).","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76251278","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}

Alumni of college stay in touch with their immediate friends and it is hard to stay connected with college mates. Contact between alumni develops business connections and to gain insight in a new field. Current students will be initially given a student login id. Access to the system can help them to seek help in their projects or for placements. This single system can satisfy almost every requirement of the alumni. Usually, alumni associations are organized in colleges, but may also be organized in a place where the alumni can meet each other. Despite the fact that there are many existing systems in colleges to maintain the alumni information, they are manual and more time consuming to current students to reach out their alumni and maintaining the privacy of the alumni. To overcome these issues, we proposed a web application which allows alumni to update their information and students can connect with them and can view the filtered events posted by alumni and admin through support vector machine algorithm.","PeriodicalId":14412,"journal":{"name":"International Research Journal of Multidisciplinary Technovation","volume":"120 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77438454","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 work, a smart and safe agriculture system is proposed that would notify the farmer about the deficit of moisture in the soil, snakes concealed under the soil, passers crossing the farm at odd times using IOT. The flame sensor and humidity sensor are deployed in farms in order to find humidity and detect fire attack. It is virtually hard for everyone to monitor the growth of plants in a large agricultural farmland. The approach that can be used to solve this problem is using IOT based sensor networks to assist the current traditional methods that are used by the farmers in order to improve their efficiency. This approach in turn significantly reduces the carbon release from agriculture which in turn will have a positive impact in solving our climate change crisis. The Indian economy accepts security in terms like protection from attacks of rodents in fields.

Due to steady increase of increasing population, there will be more generation of domestic and municipal sewage. Sewage produces obnoxious smell which causes disease to all creatures. To avoid this problem, proper treatments is necessary before disposal to land by not throwing sewage directly to natural resources and reuse the treated water that ultimately reduces the overall demand of fresh water. Its objective is to produce an environmental safe fluid waste and solid waste suitable for disposal or reuse. In one day the total sewage generated was estimated 5 MLD considering the projected population of Nagore town for the next 30 years? Consequently this paper focuses on the sewage generation in the Nagore area based on the population and sewage treatment plant is designed accordingly. It is proposed to design the various components of sewage treatment plant considering the various standards and permissible limits of treated sewage water.

A common herb like Neem leaves powder is utilized to illuminate and sterilize the water. The coagulant chemicals play the vital role in wastewater treatment. At the same time spending more amounts for these chemical coagulants increase the total treatment cost and become more burdens to the industry. In view of the replacement or reduction of chemical coagulants which are used in wastewater clarification, coagulants which are effective, productive and also free from physio-chemical characteristics are considered.
