Embedded Wireless Based Communications in Oilfield & Providing Security System
The area of the oilfield is much wider. Oil exhauster continuous working for 24 hours. As the problem of petroleum being stolen, transmission line being stolen, and transformer being stolen exists which requires the strong secures management system. With Consideration of the objective condition restriction of geographical environment, the implementation of safe management for oilfield is very difficult. We overcome these difficulties, which comes from geographical environment. The cost is not only high if the fiber cable would be lay between working station in the several tens of square kilometers, but also need to put into a lot of human and material resources with line maintenance and guard against theft. It is a perfect scheme that remote wireless monitoring and control system is established. The system is required to manage the data received from the various site and providing the security by managing and providing automatic controlling structure
Insect-Repellent and Mosquitocidal Effects of Noreremophilane- and Nardoaristolone-Based Compounds
Here, we disclose novel mosquito-repellent
synthetic hydrindanes
based on noreremophilanes and nardoaristolone B which show increased
activity against adult females of Aedes aegypti. The noreremophilanes and nardoaristolone B with hydrindane skeleton
are structurally related to nootkatone with decalin skeleton, a well-studied
natural product extracted from a grape fruit. Out of our library of
compounds synthesized based on the noreremophilanes and nardoaristolone
B scaffolds, NDS-100598 (compound 20) exhibits higher
repellent and knock-down effects at a very low concentration (0.25
mg/cm2), while a few analogues showed considerably enhanced
activity compared to racemic nootkatone. This is the first report
documenting insect-repellent and knock-down activity of the noreremophilanes
class of compounds
