Ergonomics has been used since 1850s and the application is widely used in aerospace industry, health care institution, information technology company, product design, transportation agency, training institution, nuclear engineering, virtual environmental and many more. Ergonomics is a science of designing the job, equipment and workplace to fit the workers environmental for more comfortable during the working duration. Since it related to the industry, this study is focused more to the mechanical device that is used at heavy aerospace engineering industry which is locking device design. This device is important to this industry because it is more related to safety procedure for workers during operation of certain machines. This study is aimed to improve the design of locking device for aerospace industry in term of ergonomics evaluation. Six conceptual designs were proposed and evaluated using scoring matrix technique. All of these designs were developed using computer aided design software and the highest score from the scoring matrix was proposed to replace the current device. Ergonomics analysis which is rapid upper limb assessment (RULA) is performed to evaluate the ergonomics design. From the analysis, it shows that the result of proposed design is better than existing design with highest score of 8 were reduced to score of 1 and 2. This means that the design is acceptable due to body posture of human parts from ergonomics evaluation.

We experimentally designed dispersion-managed repeaterless transmission systems with a pre-compensation and post-compensation technique using multi-channel-chirped fiber Bragg gratings. The repeaterless transmission link supports a single channel（1548.51 nm） with a 10 Gbps repeaterless transmission system over 300 km standard single-mode fiber（SSMF）. In the system design, two distributed Raman amplifiers（DRAs） were used to improve the signal level propagated along the 300 km SSMF. The co-propagating DRA provided 15 dB on–off gain and the counter-propagating produced 32 dB on–off gain at the signal wavelength. The experiment results show that the post-compensation configuration achieves an optimal performance with a bit error rate at 1 × 10-9.

Morphine is a schedule II-controlled substance that used to allow the diminution of intra-operative, post-operative orchronic pain. However, its usage is limited due to addiction and overdose liabilities. Morphine was observed to cause tolerance,dependence and withdrawal in human. Justification: to date lack of scientific evidence of morphine addiction was carried out byusing specific single human neuroblastoma cell-line (SK-N-SH). Therefore, this study was performed to establish the morphineaddiction model in this cell line. The cells were exposed to morphine for 24 hrs before treatment with methadone, as ananti-withdrawal drug for subsequence 24 hours. The cytosolic fraction of the cell was used in different objectives including receptoraffinity, withdrawal properties, endocytic machinery, desensitisation or internalisation and cellular adaptation. The result shows thatmorphine and methadone bind to the μ-opioid receptor. The morphine-treated cells were observed to increase the expression ofaddiction markers, have a low rate of the endocytic machinery, cause desensitisation of receptor and reduce cellular *** changes by morphine were normalised by the treatment of methadone. As a whole, it is postulated that neuroblastoma cell line,SK-N-SH, can be used as an in-vitro model to demonstrate morphine addiction before animal and human testing.

Starfruit (Averrhoa carambola L.) is an important fruit for Malaysian export and great attention has been made to improve starfruit fruit quality at Malaysian Agricultural Research and Development Institute (MARDI). The current study used next generation sequencing (NGS) technologies to develop starfruit simple sequence repeat (SSR) from 2 varieties namely B11 and B17 using Illumina HiSeq. The pre-processed reads were de novo assembled to generate approximately 75,000 and 74,000 scaffolds respectively. Total genome size for B11 and B17 were around 345 Mbp and 342 Mbp based on K-mer distribution analysis. In-silico microsatellite mining of each variety has identified more than 17,000 SSR in B11 and B17 respectively. Dinucleotides were the most abundant, accounting for more than 70% of all SSR and repeat motif GA (49%) was most common. A total of 239 SSR primer pairs were designed from contigs larger than 350 nucleotides and tested for amplification. The 30 polymorphic SSRs were used to DNA fingerprint of 12 starfruit hybrids. Polymorphism information content (PIC) ranged from 0.1411 to 0.6838, with an average of 0.3919. The Unweighted Pair-Group Method for Arithmetic Averages (UPGMA) dendrogram clustered 12 starfruit accessions into 2 groups.
