Emisi gas buang dipengaruhi oleh jenis bahan bakar dan kendaraan yang digunakan, karena itu untuk mengurangi kadar emisi dapat dilakukan dengan cara menyempurnakan pembakaran menambahkan catalytic converter pada knalpot kendaraan. Penelitian ini membuat alat memvariasikan penggunaan material logam agar mengetahui pengaruh sepeda motor. Metode penelitian digunakan adalah ekperimental. Variabel y...

Paraformaldehyde powder, depolymerized by heat, produced formaldehyde gas that was effective in sterilizing laboratory rooms, a mobile laboratory trailer, various surfaces, fiberglass filter medium, and specialized laboratory equipment. A sporulating and nonsporulating strain of bacteria, a virus, and a bacterial toxin were used as test agents. The dissemination procedures and equipment, the as...

The National Institute for Occupational Safety and Health (NIOSH) developed a standard for respirator certification under 42 CFR Part 84, using a TSI 8130 automated filter tester with photometers. A recent study showed that photometric detection methods may not be sensitive for measuring engineered nanoparticles. Present NIOSH standards for penetration measurement are mass-based; however, the t...

soybean mosaic virus (smv) which belongs to the virus family potyviridae, causes a disease in soybean that is present in soybean-growing areas of the world, and is widely distributed in northern iran. detection of smv is very important for disease management. in the present study several serological and molecular (nucleic acid- based) methods of rapid virus detection were compared. serological ...

The growing use of marine composite materials has led to many technical challenges and one is predicting lifetime durability. This analysis step has a large uncertainty due to the lack of data from in-service composite vessels. Analytical models based on classical lamination theory, finite-element analysis, ship motions, probability and wind and wave mechanics were used in this project to predi...

• Transformers and capacitors • Other electrical equipment including voltage regulators, switches, reclosers, bushings, and electromagnets • Oil used in motors and hydraulic systems • Old electrical devices or appliances containing PCB capacitors • Fluorescent light ballasts • Cable insulation • Thermal insulation material including fiberglass, felt, foam, and cork • Adhesives and tapes • Oilba...

This study aimed to perform an ergonomic analysis in a fiberglass parts factory. For this purpose, was used the methodology of Ergonomic Work Analysis (EWA). At the end of the study it was possible to identify some ways to the development of improvements in order to contribute to the transformation of working conditions in the sector analyzed.

The research has been conducted to test the asphalt produced in Latvia using local mineral materials and recycled modifiers (fiberglass, crumb rubber), as well used production of high-modulus mix, which will meet Latvian road construction specifications be economically, environmentally technically more attractive. In theoretical part, available sources were studied establish a framework, assess...

Carbon fiber composites are increasingly used to decrease fuel consumption in the use phase of vehicles. However, due energy intensive production, reduced may not lead life cycle environmental savings as much for other lightweighting materials, example fiberglass. This study uses assessment methodology assess how different future development routes including using bio-based raw microwave techno...
