http://ijaems.com/ Open Access international Journal to publish research paper en-us November 2020 The present study was initiated to help the simple and less expensive regeneration of activated carbons after saturation in rural area. In order to determine a regeneration time and the number of regeneration cycles, an adsorption test was necessary. Thus, 3h and 4 cycles of carbon regeneration are obtained after evaluation of the performance, percentage and adsorption capacity after each cycle. Regeneration percentages of 71.29, 54.05, 40.40, 28.06 % and 72.6, 69.84, 64.33, 34.98 %for respective concentrations of 30± 1.2 mg/L and 55 ± 1.6 mg/L are observed. Also, the performances of activated carbon 8.5, 10, 12, 20 g/L and capacities 24.04, 19.93, 14.9 and 10.35mg/g 35.7, 34.12, 31.43 and 17.09 mg/g respectively for dry season and rainy season were necessary to fix the number of cycles. The artisanal furnace with its ease of installation and its maximum temperature of 500±2°C is suitable for the regeneration of saturated activated carbon. http://ijaems.com/detail/thermal-regeneration-of-activated-carbon-saturated-with-nitrate-ions-from-an-artisanal-furnace/ Horo Koné, Konan Edmond Kouassi, Affoué Tindo Sylvie Konan, Kopoin Adouby, Kouassi Benjamin Yao http://ijaems.com/upload_images/issue_files/1IJAEMS-11020207-Thermal.pdf Pedagogical approaches and techniques are common among teachers, but some are more effective and appropriate than others. The study is focused on identifying the basic pedagogical approaches and techniques of Senior High School non-education graduate teachers (SHSNEGT) teaching General Mathematics using the purposive sampling method, the main respondents of the study are 12 SHSNEGT and two experts per school in Aliaga District, Municipality of Aliaga in Nueva Ecija. With the use of concurrent mixed-method research design and data statistical analysis, the results show that teacher-respondents whose age ranges from 25 to 38 are categorized as "young adults and professionals" and 83.33% are female with two years teaching experience in SHS, having BS Degree and specialization related in business courses as well as in their previous work. Using logical/matrix and inductive analysis and weighted mean, the subject matter-centered approach has weighted mean3.92 and the teacher-centered approach has 3.31 mean and considered dominant and "significantly evident" in teaching General Mathematics. With regards to pedagogical techniques applied by the teachers using weighted mean, "setting of objectives" has the highest weighted mean of 3.44, lesson development has 3.39, application 3.36, evaluation 3.35 and materials being used have 3.28. All items with a verbal description of “outstanding". They set their objectives based on learning competencies with three domains of learning, using board, with motivational activity on lesson development and board-work, group activity, problem sets, and quiz as a means of evaluation. Using ANOVA test analysis, previous work has significant differences in the pedagogical approaches(F=10.667, sig = .004) but there are no significant differences in terms of techniques (F=.510, sig=.65). The majority of the teachers are challenged about the attitude and behavior of the students towards learning. To develop productive notions of teaching, teachers must think of appropriate pedagogical approaches and techniques for every topic/lesson. http://ijaems.com/detail/pedagogical-approaches-and-techniques-of-non-education-graduates-teaching-general-mathematics-in-the-senior-high-school/ Cherry Rose T.

The RMB's accession to the SDR has played a role in promoting the RMB's internationalization status, opening up the international market and making the RMB become an international currency. However, at the same time, it is also necessary to clearly realize that the RMB's accession to the SDR does not have the final word as expected by the international community, and will not really increase the international holdings of RMB, which is, on one hand, restricted by "Triffin Dilemma" and "Mundellian Trilemma", and on the other hand, is as a result of the issue volume of the SDR and the inherent fragility of the real economy, resulting in the actual challenge to the internationalization of RMB. China has a long way to go to promote the internationalization of RMB, and there is still more work to be done. http://ijaems.com/detail/influence-of-sdr-on-rmb-internationalization/ Ran Wei http://ijaems.com/upload_images/issue_files/3IJAEMS-11120202-Influenceof.pdf
