OBJECTIVES A study was conducted in coke oven workers to evaluate the biological consequences of the exposure of these workers, particularly production of potential genotoxic factors. METHODS 60 coke oven workers and 40 controls were recruited in the same iron and steel works. Exposure to polycyclic aromatic hydrocarbons (PAHs) was assessed by job and measurement of 1-hydroxypyrene (1OHP) in ...

This study was aimed at assessing the efficacy of the use of the Pasteur oven as sterilization equipment in dental offices through biological monitoring. For this assessment were taken into account how adequately the material is loaded into the equipment; time/temperature used; and preventive maintenance of the oven. The data were collected in 101 dental offices in the Central District of GoiPn...

LabVIEW is a graphical programming language. LabVIEW provides the flexibility of integration of data acquisition software/hardware with the process control application software for automated test and measurement applications. In this paper, an effort is made to control the speed of the DC motor and figure out the design process of a PID temperature controlling system of the electromagnetic oven...

This study was conducted to evaluate the oxidative stability of virgin coconut oil (VCO) during oven test. VCO with and without antioxidants were subjected to oven test at 63°C over a 40 day-storage. The chemical parameters namely peroxide value (PV) and specific absorptivity of conjugated dienes (CDs) and conjugated trienes (CTs) were used to asses VCO stability. VCO samples treated with the m...

The thermal cycling stress method is popularly used to study the thermal mechanical effect on metallization films in VLSI applications, specially in interconnect systems of power IC. The fast thermal cycling stress method reported in this paper has several advantages compared with using a conventional oven for thermal stress. A special test chip is designed to demonstrate the application of thi...

OBJECTIVES It was reported previously that topside oven workers with heavy exposure to coke oven emissions had increased serum activities of hepatic aminotransferase in one coke oven plant. This study was conducted to investigate the modifying effect of CYP1A1 MspI polymorphism on liver function profiles in coke oven workers. METHODS 88 coke oven workers from a large steel company in Taiwan w...

Coke oven, which is a large industrial furnace, is complex in structure. A two-dimensional structure diagram can hardly help one observe the inner structure of a coke oven or master its working principle comprehensively. In order to solve this problem, a complete 3D digital model of a coke oven is generated by assembling the three-dimensional models of coke oven components created with SketchUp...
