Hybrid and electric vehicles feature a transmission drive with one or more electrical motors powered by Lithium batteries. Thus, Lithium batteries are increasingly used in onboard energy storage systems, leading new economical, technical and environmental challenges which are of fundamental importance in this early stage for the next automotive generation. Recycling materials from used Lithium batteries can also moderate the price of virgin materials, by reducing the price disposal as well as the dependence of manufacturers on exporting countries. Furthermore, recycling Lithium-ion batteries has significant environmental benefits, such as containing the risk of chemical pollution and improving safety in storage facilities for exhausted batteries worldwide. This paper aims to provide a comprehensive insight on Lithium-ion battery recycling for scientific research and industrial applications, examining the economic, technical and environmental aspects of this topic.","PeriodicalId":12520,"journal":{"name":"Global Journal of Research In Engineering","volume":"21 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2020-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72887208","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}

Turkey is a country, which seismically settled at one of the most active regions in the world, and earthquakes with high magnitude frequently occur here. There are some regions, which are severely under threatening of earthquakes. One of them is the Marmara region with twenty-four million people. This region, namely the Marmara basin, has at least forty-five large dams with different types. This study considered nineteen of them to relieve their seismic hazard parameters for all dam sites and total risk for each structure. The study area is lying in a seismically, very active part of Turkey. The southern part of the basin is structurally cut by the North Anatolian Fault, which is a famous structural feature that produces deathful earthquakes, and its offshoots. The analyses have indicated that peak acceleration widely ranges for the nineteen dam sites of this basin. The total risk analyses have concluded that most of the dams in the metropolitan area have high-risk classes and a significant effect for public safety.","PeriodicalId":12520,"journal":{"name":"Global Journal of Research In Engineering","volume":"25 1","pages":"25-36"},"PeriodicalIF":0.0,"publicationDate":"2020-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87546773","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 complexity in obtaining the solution to this singular problem is due to the nonlinear dynamics of the system model, the presence of control variables in linear form and the existence of constraints in both the state and control variables. Traditionally, during the optimization process, uncertainties associated with design variables, control parameters and mathematical model are not considered. In this contribution, a systematic methodology to evaluate uncertainties during the resolution of a singular optimal control problem is proposed. This approach consists of the Multiobjective Optimization Differential Evolution algorithm associated with Effective Mean Concept. The proposed methodology is applied to determine the feed substrate concentration in fed-batch penicillin fermentation process. The robust multiobjective singular optimal control problem consists of maximizing the productivity and minimizing the operation total time. The overall profit is considered as a postprocessing criterion in the choice and implementation of a result contained in the Pareto set. The results obtained indicate that the proposed methodology represents an interesting approach to solve this kind of problem.","PeriodicalId":12520,"journal":{"name":"Global Journal of Research In Engineering","volume":"24 1","pages":"23-30"},"PeriodicalIF":0.0,"publicationDate":"2020-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91008237","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 government of Bangladesh has attached to a commitment to implement the Rooppur Nuclear Power Plant, and so Bangladesh will be the 33 nuclear powerproducing country after the successful construction of this plant. Bangladesh has planned to construct two power units (Rooppur-1 & Rooppur-2) with a capacity of 1200 MW, each of and is expected to go into operation in 2023. Russian Rosatom State Atomic Energy Corporation is constructing this nuclear power plant, which is the generation-3+ VVER-1200 model. But the main concern is how a third world country like Bangladesh can handle the tons of radioactive waste of RNNP. Radioactive waste i.e., a variety of solids, liquids, and gases which are produced during the generation of nuclear energy in a nuclear reactor. Depending on activity content, solid and liquid waste are disposed of in near-surface or deep geological facilities, and gaseous waste is dissolved by following some filtering process. If not properly disposed of or recycled, irradiation from radioactive waste will cause major problems for the environment. Various stages should be required for the removal of a tremendous amount of radioactive waste in a costeffective way. This paper mainly delineates the proximate of radioactive waste management of RNNP and gives an account of (1) Radioactivity and radiation level, (2) Classification, (3) Treatment of solid, liquid and gaseous radioactive waste, (4) Reprocessing and packaging, (5) Storage and (6) Disposal.","PeriodicalId":12520,"journal":{"name":"Global Journal of Research In Engineering","volume":"23 1","pages":"69-79"},"PeriodicalIF":0.0,"publicationDate":"2020-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89946097","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}

Primary industries demanding refractories include the manufacturing of steel, non-ferrous metals, glass, lime, cement, ceramics, petrochemicals and incineration. Refractory grade bauxites (RGBs) are high-alumina materials used as aggregates in shaped and unshaped refractory linings suitable to withstand high temperature heating and a corrosive environment. Despite the wide availability of bauxite ores in the world, few countries can supply a bauxite with refractory grades. Guyana, China and Brazil have emerged as suppliers for the refractory industry and the peculiarities of each bauxite from these countries impact directly on the refractory and how the manufacturing process can impact the refractory properties. The Guyanese RGB presented the highest alumina content (~90% Al2O3). However, a Brazilian RGB with lower alumina content (~85% Al2O3) presented the highest hot modulus of rupture value (HMoR at 1200°C/5h = 5.12 MPa). As for the Chinese RGBs, these presented a higher heterogeneity, evidenced in variation on chemical composition resulting in worse thermo mechanical performance (HMoR< 4.10 MPa). Two different forming process for Brazilian RGBs showed that the briquetting operation produces angularshaped grains (sphericity = 0.7), whereas the extrusion mechanism produces rounded grains (sphericity = 0.9) which","PeriodicalId":12520,"journal":{"name":"Global Journal of Research In Engineering","volume":"12 1","pages":"51-67"},"PeriodicalIF":0.0,"publicationDate":"2019-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79852072","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}
