Study on Decarbonization effect of Ship exhaust Based on Temperature

Research Article of Journal of eSciences Study on Decarbonization effect of Ship exhaust Based on Temperature LI Ke, WANG Zhongcheng, LI Pinyou Merchant Marine College, Shanghai Maritime University, Shanghai 201306, China In order to investigate the effect of temperature of absorption liquid and exhaust temperature of diesel engine on decarbonization efficiency of marine decarbonization tower, the effect of temperature on carbon dioxide absorption efficiency in ship exhaust was studied by means of theory, experiment and simulation. Because of the particularity of the experiment, three exhaust temperatures of 25, 45 and 65 degrees celsius are mainly set up in this paper. The relevant experimental data are collected and analyzed under idle speed, 25% load condition, 50% load condition and 75% load condition, respectively. The experimental results show that under the same load, when the exhaust gas temperature increases, the absorption efficiency shows a downward trend. and the experimental exhaust gas temperature was simulated by Aspen plus software from 35 to 200 degrees celsius respectively. the simulation results show that the absorptivity decreases with the increase of temperature, and the simulation results are consistent with the experimental results, which has a certain reference for the design and operation parameters selection of marine decarburization tower.

Causes Affecting Parental Involvement In The Schooling Of Children

Review Article of Journal of eSciences Causes Affecting Parental Involvement In The Schooling Of Children Yayew Genet Chekol and Ketema Joro Ayane Salale University Parental involvement (PI) in the education of children is not a recent phenomenon. PI has become an established feature of education policies across the developed world. The study set to establish factors that may make parents choose not to participate in education process or unable to become more involved. The study was grounded in Epstein’s overlapping spheres of influence theory. A qualitative case study was employed. Purposive sampling was used to select (4) schools and (40) participants in Alefa district, Central Gondar Zone, Ethiopia. Findings revealed that the economic status and level of education of parents have a significant effect on children’s education. It also emerged that parents are more likely to be involved when teachers’ perceptions about role of parents are positive. The study established that PI is also influenced by age of children. The study recommends that parents be helped to appreciate the benefits of parental involvement in the learning of their children. Workshops should be established to develop the relationship between parents and their children. Keywords: Parent, education, parental involvement, school, community ...

Assessing The Teaching-Learning Roles Of Instructional Leadership In Some Selected Primaey Schools

Research Article of Journal of eSciences Assessing The Teaching-Learning Roles Of Instructional Leadership In Some Selected Primaey Schools Yayew Genet Chekol and Ketema Joro Ayane Salale University The purpose of this study was to investigate teaching –learning roles of instructional leadership in the full cycle primary schools of Chilga woreda, Central Gondar Zone. To meet the objectives of the sudy descriptive survey design was employed. Teachers, principals, supervisors, and woreda education officers were used as primary sources of data, and annual reports and different document records used as secondary sources of data. Regarding to sampling, teachers were selected by lottery method, and principals, supervisors and woreda education officers were selected by purposive sampling method. Questionnaires, interview and document analysis were used as data collection instruments and the data were analyzed through mean, standard deviation and compare means. The finding of this study revealed that almost all instructional leaders were subject specialists, lacks skill and training, and lacks commitment and moral to accomplish their tasks and severe shortage of finance. Based on the findings, it was concluded that: Schools were to some extent incapable of enhancing teachers’ professional skill development and improving the quality of education. The stated vision and defined mission in the school did not command the ownership of its potential stakeholders since it was not supported by its potential stakeholders. Instructional leaders did not possess the required skill, knowledge and attitude through training. In line with the above findings and conclusions it was recommended that: to equip instructional leaderships with necessary knowledge, attitude and skills the Region, Zone and Woreda Education Officials may arrange workshops, seminars, short and long term training in collaboration with different universities, colleges and NGO’s and schools need to think of their own income generating sources on top of government budget through improving their ...
