peppermint (mentha piperita l.) from lamiaceae family is one of the most important medicinal plants, used in food, sanitary and cosmetic industries. a field experiment was carried out in ferdowsi university of mashhad in 2010-2011 to evaluate the effects of three irrigation levels (100, 80 and 60 percent of water requirements calculated by evaporation pan class a) and two mulch types (black pla...

The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

scaling (that is, Dennard scaling) provided three benefits: doubling of integration capacity to deliver twice the number of transistors per unit area every two years at constant price, increased transistor performance, and reduced energy per transistor. With the steady erosion of the latter two benefits, the low-hanging fruit for performance increase has been to exploit integration capacity via...

More people feed birds and other wildlife than hunt and fish combined. Despite its popularity, many bird-feeding traditions lack scientific data. We examined seed and feeder use by wild birds in the United States and Canada, and how seed use may change by season and geographic region. Between 2005 and 2008, 173 individuals from 38 states and 3 provinces in Canada made 20,077, 45-minute observat...

The reverse engineering process for VLSI chips is a complex operation that can cost from $10,000 for the simplest chips to hundreds of thousands of dollars for complex chips. In this study, we present an overview of the process of reverse engineering VLSI chips. The study outlines the steps involved in the process of reverse engineering chips as well as the different techniques used to extract ...
