The recent expansion of power-distribution networks has motivated many researchers to study how minimize the costs such projects. Although transmission towers present one main items in network that greatly affect project budget, there are no clear criteria or recommendations select optimum bracing system minimizes tower weight. This research presents configurations for latticed power-transmissi...

Abstract The delamination of copper lead frames from epoxy molding compounds (EMC) is a severe problem for microelectronic devices, as it leads to reduced heat dissipation or circuit breakage. micro/nanoscale surface structuring promising method improve the copper–EMC interfacial adhesion. In this study, generation micro/nano hybrid structures on surfaces through femtosecond pulsed laser irradi...

abstract strawberry is one of the most important fruit crops in the world. in this study, effect of different plant densities were studied on yield and fruit quality of strawberry 'selva' in greenhouse and laboratories of university college of agriculture and natural resources during 2002-2003. uniform stolens of strawberry were planted in holes of plastic column according to factorial in compl...
