A prototype of a solar power tower system was designed and constructed to produce electricity from solar energy. This prototype of a solar power tower system was constructed and installed at King Abdulaziz University in Saudi Arabia where solar intensity is excessive. Heliostats were implemented to capture the solar rays during daylight. These mirrors are used to direct the solar energy to a so...

Natural Hazard Triggered Technical Accidents (Natech) cause serious loss of life, environment and property affect life negatively. Risk analysis studies these accidents are important. In this study, it was aimed to analyze the risk Natech for Türkiye. Statistical evaluation made through various databases selecting province organization where application will be made. Because evaluations, two ex...

In order to determine the extent of acaricide resistance in the eastern region of the Eastern Cape Province 1-, 2- and 3-host ticks were collected from cattle at 59 dip-tanks over a period of 2 years. These ticks were tested for resistance against 3 compounds, namely amitraz, cypermethrin and chlorfenvinphos. The Shaw Larval Immersion Test detected emerging resistance to amitraz in Rhipicephalu...

The flow in stormwater tanks has a major impact on their treatment efficiency. A measurement method and an evaluation method was developed to identify unfavourable flow conditions in existing sedimentation tanks. The data base is provided by mobile, event-controlled measurements of tracerbased hydrographs. The analysis is based on transfer functions known in system theory. The model parameters ...

In the course of the investigation into the bacteriology and epidemiology of cholera, which we are at present conducting in the Asansol Mining vSettlement, we found that during the hot dry months of the year (February to June)?which also constitute the epidemic season in that area? vibrios were extremely numerous in the smaller village ground tanks much used by the inhabitants for bathing; the ...

Temperature distribution is a critical indicator of the health condition for Liquefied Petroleum Gas (LPG) storage tanks. In this paper, we present a large-scale wireless temperature monitoring system to evaluate the safety of LPG storage tanks. The system includes wireless sensors networks, high temperature fiber-optic sensors, and monitoring software. Finally, a case study on real-world LPG s...
