    Design for Manufacturing (DFM) and Design for Assembly (OF A) are comprehensive approach to integrating the design process with production methods, materials, process planning, testing, and quality assurance. DFM and DFA require a fundamental understanding of the characteristics, capabilities, and limitations of materials, manufacturing processes, machinery, equipment, and tooling and variability in machine performance, dimensional accuracy and surface finish of the workpiece, processing time, and the effect of processing methods on product quality. Establishing quantitative relationships is essential in order to be able to analyze and optimize a design for ease of manufacturing and assembly at minimum product cost. This project focused on the assessment of implementation of the DFM and DFA during prototype development process. Centrifuge was selected as the example in this project. The centrifuge was designed for offshore facility. Information such as design, parts manufacturing process, and assembly were analyzed in this project to assess the implementation of this approach during the prototype development cycle. It is noted that the application of the DFM and DFA have contribute to the success of the prototype developmen

    Performance-based reward administration as an antecedent of job satisfaction: a case study of Malaysia’s fire and rescue agencies

    Get PDF
    Performance based reward administration is a crucial aspect of organizational reward system. Recent studies reveal that the ability of administrators to appropriately implement communication, participation and performance appraisal in planning and implementing performance-based reward system may have a significant impact on job satisfaction. Although the nature of this relationship is interesting, the role of performance-based reward administration as an important antecedent has not been adequately explained in organizational reward models. This study was undertaken to examine the correlation between performance-based reward administration and job satisfaction in Malaysia. Primary data were gathered from 168 self-report questionnaires completed by employees of fire and rescue agencies in Peninsular Malaysia. The results of SmartPLS path model analysis showed that performance -based rewards administration was positive and significantly correlated with job satisfaction. Overall, the result demonstrated that the capability of administrators to appropriately implement communication, participation and performance appraisal in managing performance based reward system may lead to greater job satisfaction in the organizations studied. Future studies could do well to delve further into aspects of performancebased rewards in organisations such as organizational and personal characteristics, patterns, direction and magnitude of causal relationships, and behavioural elements of organizational justice

    Despite significant increase of interest in job motivation among the global organizations, the role of an administrator is still unclear. The main objective of this study is to investigate the relationship between job satisfaction (i.e., intrinsic satisfaction and extrinsic satisfaction) and job motivation. A survey method was used to collect self-report survey of employees in Malaysian Fire and Rescue Department. The SmartPLS path model analysis revealed three key findings: first, job satisfaction is significantly correlated with job motivation. Second, intrinsic satisfaction is significantly correlated with job motivation. Third, extrinsic satisfaction is significantly correlated with job motivation. These findings demonstrate that the ability of administrators to provide adequate intrinsic satisfaction and extrinsic satisfaction may lead to greater employees’ job motivation. In addition, discussion, implications and conclusion are also presented

    Investigating GAP45 localisation and phosphorylation during plasmodium falciparum schizont development

    The invasion of erythrocytes by merozoites is driven by an actomyosin motor assembled below the parasite’s plasma membrane, with the myosin anchored on the inner membrane complex (IMC). The myosin (MyoA) is within a protein complex that is comprised of several proteins including myosin tail domain interacting protein (MTIP) and glideosome associated proteins (GAP) 45 and 50. A ternary complex of MyoA, MTIP and GAP45 is formed and later associates with GAP50. GAP45 is acylated by both myristoyl- and palmitoyl-fatty acids and is phosphorylated. This study has highlighted the GAP45 phosphorylation by calcium dependent protein kinase 1 (CDPK1) in vitro and its possible roles in schizogony. By site directed mutagenesis, substitution of S31, S89, S103 and S156 to alanine decreased the level of GAP45 phosphorylation, with S103A exhibiting a major decrease in 32P incorporation. Phosphorylation on S89 and S103 was studied further in parasites as both residues were among the phospho-sites in phosphopeptides identified in vivo. This study also showed that full length GAP45 labelled internally with GFP (FL-GAP45) is assembled into the motor complex, phosphorylated and transported to the developing IMC in early schizogony, where it accumulates during intracellular development until merozoite release. The C-terminal truncated GFP-GAP45 (N-GAP45; residues 1-29) localised at the plasma membrane instead of the IMC and was not assembled into the motor complex. The N-terminal truncated GFP-GAP45 (C-GAP45; residues 30-205) behaved like FL-GAP45. Modifying serine residues, S89 and S103, in GAP45 with alanine or aspartate had no apparent effect on its assembly into the protein complex or its intracellular location during schizont development and merozoite maturation. A second highly phosphorylated component of the complex (GAP40) was also identified. The early assembly of the motor complex suggests that it has functions in addition to its role in erythrocyte invasion

    Assessment of amino acid decarboxylase activity can be conducted using tubed broth or plated agar. In this study, the test was carried out in microtitre plates containing lysine, ornithine, arginine, tyrosine, tryptophan, phenylalanine or histidine as biogenic amine precursors. Møller decarboxylase base broth (MDB) with or without 1% of a known amino acid were added to wells of a 96 well-microtitre plate. The wells were inoculated with Escherichia coli, Klebsiella pneumoniae, Acinetobacter anitratus or Staphylococcus aureus to the final concentration of 6.0 x 10(7) cfu/ml and incubated at 35ºC. The absorbance of the culture broth was read at 570 nm at 0, 1.0, 2.0, 3.0, 4.0, 5.5, 6.5 and 7.5 hour. Comparison of means of A'(570) between 0 hour and a specified incubation time was determined statistically. Positive decarboxylase activities were detected in the media inoculated with E. coli and K. pneumoniae in less than 6 hours. The current method is suitable for immediate producers of amino acid decarboxylase enzymes. It costs less as it uses less amino acid and it has the potential to be used for screening aliquots of food materials for amino acid decarboxylase activities
