eight forage sorghum cultivars (sweet jumbo, nectar, chopper, pacific bmr, speed feed, kfs1, kfs2 and kfs3) were assessed to determine the most suitable traits carrying cultivar, through a randomized complete block design with four replications during 2003-2005. ammonium phosphate (basd on p2o5) was applied at 115 kg/ha and 183 kg/ha of nitrogen (urea-based) at four application times. six trait...

The developmental variation in stem height with respect to stem diameter is related to a broad range of ecological and evolutionary phenomena in trees, but the underlying genetic basis of this variation remains elusive. We implement a dynamic statistical model, functional mapping, to formulate a general procedure for the computational identification of quantitative trait loci (QTLs) that contro...

Due to their theoretical advantages, hip systems combining modular necks and large diameter femoral heads have gradually gained popularity. However, among others, concerns regarding changes in the load transfer patterns were raised. Recent stress analyses have indeed shown that the use of modular necks and big femoral heads causes significant changes in the strain distribution along the femur. ...

investigation on structure and dynamics of natural forest ecosystems is an important issue for silvicultural decisions. the aim of this study is to analysis dynamics and structure of a beech stand during 5-year period in the shast kalateh forest in the caspian region, north of iran. data were collected from a 16.9ha permanent research plot established in a natural unlogged stand in 2006. all li...
