The is one applications or appliance that perform task use radiation. consists PV array, pump, inverter, AC pumping device etc. Solar radiation converted in electrical current power source which then used draw directly ground, wells, rivers, lakes In this ...
The use of battery tools is very common in many fields work. In fact, the electric engine and batteries have several advantages over traditional endothermic engines, including low emissions, terms pollutants, vibration noise. this context, chainsaw market started producing models powered by batteries. These machines can be useful forestry, but information on their performance scarce. aim work w...
Monitoring and analysis of high frequency acoustic emissions on marine diesel engines may indicate their condition with the aim to increase engine availability and reduce maintenance overheads for the Defence Force. An experimental study was undertaken to evaluate the application of acoustic emission (AE) sensing to the monitoring of both petrol and diesel internal combustion engine operating c...
Background: Petrol station attendants are a high risk group and are exposed to occupational hazards with no control over the length and frequency of safety regulation. The study aimed to assess the knowledge of petrol station attendants about the occupational hazards they are exposed to and the safety practices used to prevent them.

Possible biochemical changes in hepatic and renal functions due to exposure of petrol vapour were assessed in twenty (20) petrol station attendants in Owerri, Imo State, Nigeria. A corresponding twenty healthy subjects who were not exposed to petrol or its vapour were used as controls. The results showed a significant increase in the (p<0.05) activities of alkaline phosphatase, alanine and aspa...
