Though beekeeping is a common farming enterprise and income generating activity in Atsbi Wemberta district, and promotional efforts have been made to improve it, no systematic study has been undertaken to evaluate the promotional efforts and people’s response to it. The objectives of this study were to identify determinants of improved box hive adoption by the beekeepers; and to analyze financi...

artemisia annua is still the only commercial source of artemisinin. to date, a number of biochemical and molecular studies about artemisinin’s biosynthetic pathway have been carried out. in metabolic engineering approach, isolation and characterization of promoters leads to an understanding of which cis-acting elements are responsible for the regulation of gene expression. dbr2 is a key enzyme ...

Software testing is the process used to measure the quality of developed computer software. It exhibits all mistakes, errors and flaws in the developed software. In this paper, the three most prevalent and commonly used software testing techniques for detecting errors are described and compared, they are: white box testing, black box testing and grey box testing. Keywords— Black box, Demonstrat...

the alternative double bonds and conjugation in the polyene compounds are one of the main properties in these compounds. each carbon-carbon bonds in a polyene compound along the chain has appreciable double-bond character. the p-electrons are therefore not localized but are relatively free to move throughout the entire carbon skeleton as an one-dimensional box. the skeleton be considered as a r...
