Natural Resource Beta Wave Technology To Stimulate Rural Primary Education
Teik Wei YEAP,Salleh ABD RASHID 한국직업자격학회 2017 한국직업자격학회 학술대회 Vol.2017 No.10
The purpose of this study is to evaluate the effectiveness of using Natural Resource Beta Wave Technology (NRBWT) in literacy to stimulate students with learning disabilities in chinese primary school in Perlis, the Rural Northen State in Malaysia. This quantitative research was designed using Quasi-experimental method. 31 respondents selected as a sample in Sekolah Jenis Kebangsaan Cina (SJKC) in Perlis, Malaysia. This study was treated with Simulation Beta Wave with 20Hz for a period of 9 weeks and without any controlled sample treatment group. A cognitive test of C1 and C2 where ‘C’ stands for ‘construct’ tool was used to collect data before and after the intervention was done. Amidst the treatment, the pre-test and post-test achievement tests were conducted to evaluate the effectiveness of the Beta Wave of 20Hz. The findings of this study was analyzed using the SPSS 22 with descriptive mean, frequency, % and multiple regression. The results indicates that the effect of Beta wave green technology with 20Hz gives significant positive influence in the learning of students with learning disabilities as a Northen Rural State in Malaysia.

Continuous production of carbon nanotubes – A review
Lim Siang Ying,Mohamad Amran bin Mohd Salleh,Hamdan b. Mohamed Yusoff,Suraya Binti Abdul Rashid,Jeefferie b. Abd. Razak 한국공업화학회 2011 Journal of Industrial and Engineering Chemistry Vol.17 No.3
Carbon nanotubes (CNTs) up to now are the most researched materials of the 21st century with an international intention of growing industrial quantities due to their superior properties for use in many applications. Thus far large quantities of carbon nanotube scan be grown in a continuous manner by both arc as well as chemical vapour deposition methods. In this paper, an innovative approach of feeding gases, a carbon precursor (solid or gases) and a catalyst into the reaction zone is reviewed. This is followed by a study of the reaction process concerning how the method is initiated, the effect of growth environment and catalyst on CNTs as well as the dischargingmechanism for the final carbon products. A study of the arc method consists of a novel way of growing CNTs in a liquid solution from an arc discharge generated by carbon rods, by growing CNTs in a plasma zone using carbon gases or solid carbon and a more direct method of using carbon tape as the anode for the synthesized source are also reported. In the case of the chemical vapour deposition (CVD) method, some use a horizontal reactor and some use a vertical reactor with all having different installed devices for use in continuous feeding and discharging of resources and products respectively. Additionally, problems regarding the CNT yield and some issues that have not been taken into consideration by others, are discussed. At the end of the review, an additional mechanism to integrate catalyst preparation and carbon nanotube purification into the current research synthesizing process for future study is proposed for a highly productive continuous CNT synthesis process.
