The Microbicides Development Programme evaluated the safety and effectiveness of 0.5% and 2% PRO2000/5 microbicide gels in reducing the risk of vaginally acquired HIV.In February 2008 the Independent Data Monitoring Committee recommended that evaluation of 2% PRO2000/5 gel be discontinued due to futility.The Africa Centre site systematically collec
Bottom trawling is one of the most efficient fishing activities, but serious and persistent ecological issues have been observed by fishers, scientists and fishery managers.Although China has applied the Beidou fishing vessel position monitoring system (VMS) to manage trawlers since 2006, little is known regarding the impacts of trawling on the sea
Clogging and blockage of water transmission pipelines is one of the problems that reduce discharge downstream by creating various sediments.The aim of this study was to identify and remove the constraints caused by sediment in the water transmission lines of Sarcheshmeh copper complex to agricultural lands of downstream areas.First, the formed sedi
Traffic accidents usually cause congestion and increase travel-times.The cost of extra travel time and fuel consumption due to congestion is huge.Traffic operators and drivers expect an accurately forecasted accident duration to reduce uncertainty and to enable the implementation of appropriate strategies.This study demonstrates two non-parametric
