An Empirical Examination Of Management Control Systems In Just-In-Time Manufacturing

Proponents of JIT techniques often argue that Japanese manufacturing techniques are among the best in the world. On the other hand, critiques have called the JIT manufacturing techniques “management by stress” and that they are often associated with high work intensity, stress, and fatigue. Prompted by some recent findings, organizational theorists began to question whether these new work practices will have a sustaining effect on performance. Consistent with the social technical systems theory, this study suggests that unless complimentary changes also occur in other related systems within an organization, the perceived productivity gain of a new work system may not be realized. Findings provide some support for the hypotheses tested. For example, results show by itself JIT does not lead to performance gains. Similarly, findings show that incentive pay or extrinsic motivation per se is not associated with better manufacturing performance. Instead, results show JIT interacts with performance goals to produce lower manufacturing costs only when incentive pay is used. For plants using fixed pay, however, manufacturing costs are a decreasing function of performance goals but a marginal increasing function of JIT

Effects of ethanol extract of Zea mays hairs on liver function tests in alcohol fed rats

The ethanol extract of Zea mays hairs was screened for the effects on liver functions in alcohol fed rats. 30 male Sprague dawley rats were divided into six groups with five rats in each group. There were control group, 50mglkg body weight extract group, alcohol group, 50mglkg body weight extract+ alcohol group, 100 mglkg body weight extract group and 100 mg/kg body weight extract + alcohol group. All six groups were treated for 14 days. The ethanol extract of Zea mays hairs increased total protein and globulin significantly in high dose (IOOmg). 3ml of 30% alcohol also increased these two parameters (increase in total protein was non significant). The extract with alcohol, increased the total protein and globulin more than the extract alone. Albumin also showed non significant increase in 50mg, 1 OOmg extract and 50mg extract with alcohol. But alcohol alone decreased albumin significantly. As filr as the liver enzymes are concerned, there was no significant change in alkaline phosphatase (ALP), aspartate aminotransferase (AST) and alanine aminotransferase ( AL T). The results showed that the extract increased protein synthesis in the liver and did not cause any damage to the liver. 3 ml of30% alcohol when given for 14 days did not cause any adverse effect on protein synthesis and also did not cause any affect to the enzymatic functions of the liver. x

Relation of parallel resistance to the passive double SAW resonator

This paper presents the relationship of parallel resistor to the frequency response of the passive remote acoustic wave resonators (SAWRs) sensor system in 433.42MHz and 433.92MHz. Impedance matching is achieved with the connection of L-network to the parallel SAW resonator. The main objective of this finding is to improve the sensor of narrow bandwidth application. Circuit with high quality factor (Q factor) has better suppression for narrow band application. Parallel resistor improves the system by increasing the Q factor. Increasing the parallel resistance will decreased the bandwidth of the resonant frequency. Simulation results of the system are presented and discussed

Treatment Of Textile Wastewater Using Hibiscus Rosa-Sinensis (Bunga Raya) Leaf Extract As Caogulant

Treatment of textile wastewater is one of the largest problems faced by the textile manufacturers in Malaysia. This study was conducted to investigate the efficiency of Hibiscus rosa-sinensis or Bunga Raya leaf extract as coagulant and coagulant aid with poly-aluminium chloride (PACl) for the treatment of textile wastewater. Evaluation was based on the removal of chemical oxygen demand (COD), suspended solids (SS), color as well as the influence on zeta potential and particle size using standard jar test apparatus

Sensitivity study of graphene nanoribbon with NH3 at room temperature

This study presents the sensitivity of graphene nanoribbon (GNR) when exposed to ammonia gas at room temperature. Alumina were used as a substrate and coated with GNR as sensing film for ammonia gas detection. Four different concentration of GNR in the category of maximum, high, low, and minimum were prepared. Each category of GNR will be dispersed on alumina substrate with area of 1cm² and 4cm². 30nm of gold contacts are sputtered on both ends of the sensing film. The ammonia gas can be detected by measuring the changes in resistance. The GNR as ammonia sensor shows good responses at room temperature. In repeatability test, maximum GNR shows least variation when exposed to ammonia with the value of 1.01% (4cm²) and 2.12% (1cm²). In a sensitivity test, 0.25% to 1.00% of ammonia gas was used and tested on maximum GNR. Maximum GNR on 4cm² substrate shows higher sensitivity as compared to 1cm². Reaction time of GNR on ammonia gas decreased as the concentration of ammonia increased. Larger surface area of sensing element required lesser reaction time

Assessing water quality of Murum Reservoir halfway through impoundment

This paper reports the water quality of Murum Hydroelectric Reservoir, eight months after impoundment of the dam. A total of nine stations were selected in the reservoir. Temperature, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD5), chlorophyll-a and total suspended solids (TSS) were studied. The results showed that the water was warmer at 0.5 m depth. As the depth increased, temperature in the reservoir decreased in the range of 4.40°C to 7.35°C from 0.5 to 20 m depth. The concentration of DO dropped to zero at 4 - 6 m depth leading to anoxic level. pH at 0.5 m depth ranged from 6.40 to 7.20 and they were significantly higher (p<0.05) than those at 10 and 20 m. Chlorophyll-a at 0.5 m were in the range of 4.61 to 20.50 mg/L, relatively higher compared to 10 m and 20 m depths. The results obtained indicates that impoundment of Murum River generally caused water quality deterioration. In addition, this could be due to anthropogenic activities such as plantation and logging activities that are still going on within the catchment during the impoundment. Therefore, further continuous monitoring and investigation is required to determine the long-term water quality condition and identify factors that influence water quality in Murum Reservoir

Silicon nanowire interface circuit for DNA detection

Detection and quantification of DNA is critical to many areas of life sciences and health care, from disease diagnosis to drug screening. The transduction of DNA through electrochemical methods have a fast response rate and with a conductometric device like the silicon nanowire which can be fabricated to have a similar diameter of the DNA molecule being targeted, detection is real-time. Critical to this is the interfacing of a current-source and an amplifier capable of achieving a maximum of 10 pico ampere input bias. In this project, we fabricated a silicon nanowire using the top down approach and built a circuit that can mimic the output signal as low as 12 nA and achieved a gain of 1 million to be interfaced with the nanowire for real-time DNA detection
