To design and develop a comfortable driver’s seat, cheaper in cost and adds value to the customer is an important issue in an automotive industry. It is tough to design such a driver car seat. However, taking account all these things many researchers have put effort to design and developed a driver car seat considering various aspects (e.g. Biomechanical, materials, vibration absorption, safety...

Kebutuhan kursi roda di Indonesia sangat tinggi namun dalam pemenuhannya masih impor. Kursi adaptif lokal mengalami kekalahan pasar negeri karena beberapa permasalahan produksi seat and back cushion. Penelitian ini bertujuan mengevaluasi yang ada saat dan mengembangkan desain baru untuk mendapatkan efisiensi efektivitas produksi. Reverse engineering merupakan langkah tercepat melakukan evaluasi...

Polyurethane-immobilized Flavobacterium cells (ATCC 39723) degraded pentachlorophenol (PCP) at initial concentrations as high as 300 mg liter-1. The reversible binding of PCP to the polyurethane was shown to be important in the protection of the cells from inhibition of PCP degradation. The degradation activity of the bacteria was monitored for 150 days in semicontinuous batch reactors. The deg...

A sensitive methodology for PCR detection of Staphylococcus aureus or Bordetella pertussis DNA within cot mattress polyurethane foam was developed. The assay's applicability was evaluated on polyurethane foam from used cot mattresses. S. aureus DNA was detected in 42% of mattresses of sudden infant death syndrome (SIDS) victims and 29% of comparison group (no death) mattresses tested. B. pertus...

Silicone is a polymer widely used for medical purposes, including breast implants. The aim of this work is to verify the occurrence of silicone gel diffusion through the lining membrane (bleed) of gel breast implants with smooth, textured, and polyurethane foam coated surfaces, sterilized by dry heat and ethylene oxide. The results enable us to conclude that there is significant difference for ...

Spray application of polyurethane foam for thermal insulation of buildings represents the polyurethane application with the highest potential worker exposure to MDI. This paper reviews the existing work done to characterize the MDI exposures of the sprayed polyurethane foam workers as well as identifying several elements of an effective industrial hygiene program suggested by the existing work....

Several operational and prototype ejection seat cushions were selected for the evaluation of their performance for the prevention and reduction of spinal injuries. The evaluation was performed using impact tests on the vertical deceleration tower, where a cushion was placed between the seat pan and the occupant (a 50 percentile Hybrid III manikin) and was subjected to +Gz impact at 8, 10, and 1...
