The selection of an optimum location for the installation a Concentrated Solar Power (CSP) plant is very vital to its overall performance. Any selected should suitably satisfy some favourable criteria such as high direct normal irradiance, ambient temperature, lower wind speed, level cloud cover and availability source water. In this paper, optimal location(s) CSP in Ghana achieved using Analyt...

The optimal location of sensors involves the selection of type, number and location of sensors from a set of available instruments with certain values of cost, precision and reliability. The optimal design not only satisfies economic criteria, but also some requirements on the quality of key variable estimates. In this work, a methodology for solving the sensor network design problem based on E...

Host plant selection by insects is often divided into „host plant finding‟ and „host plant acceptance.‟ While the two are easy to separate conceptually, in practice, they are really part of a continuum of three, rather than two, inextricably bonded links. However, the central link of host plant finding, thought previously to be governed by volatile chemicals, has, until now, proved intractable ...

In this review, the use of the most common selection marker genes on plant transformation and the effects of their respective selective agents are discussed. These genes could be divided in two categories according their mode of action: genes for positive and negative selection. The retention of the marker gene flow through chloroplast transformation is also discussed. Further, strategies to re...

Open access, freely available online " Some qualities nature carefully fi xes and transmits, but some, and those the fi ner, she exhales with the breath of the individual as too costly to perpetuate. But I notice also that they may become fi xed and permanent in any stock, by painting and repainting them on every individual, until at last nature adopts them and bakes them into her porcelain " —...

Three faba bean (Vicia faba L.) cross populations, i.e. Giza 40/Giza 3 (Cross No.1), Slaim/Giza 3 (Cross No.2) and Slaim/311/1170/81 (Cross No.3), were made for selection by three methods, i.e. Mass selection (MSM), pedigree selection (PSM) and Picking-pod (PPM) from F to F generation during 2005/2006, 2006/2007 and 2 4 2007/2008 seasons at Mattana Agricultural Research Station, ARC, Isna, Qena...
