Uncemented hip replacement matches the best results of classic cemented replacements. With the aim of preserving bone and soft tissue, implants with shorter stems and proximal metaphyseal support have been developed. Likewise, the lack of distal load should avoid cortical diaphyseal remodelling phenomena and the thigh pain of some cylindrical and wedge implants. The resurfacing implant, very po...

objective: in this study the efficacy of two agent of this biological control agent of corn stem borer in corn fields compared with common synthetic insecticides endosolfan to find a suitable alternative for chemical control of pests in corn fields. methods: in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized ...

This paper examines the phenomenon of consonant spreading in Arabic stems. Each spreading involves a local surface copying of an underlying consonant, and, in certain phonological contexts, spreading alternates productively with consonant lengthening (or gemination). The morphophonemic triggers of spreading lie in the patterns or even in the roots themselves, and the combination of a spreading ...

in this paper, to simulate mechanical stress on the cutter bar of the harvesting combine during cutting of wheat stems, first, shearing strength of the stems was measured for various moisture content levels and cutting heights. after that the cutter bar of combine was simulated by abaqus with the specified conditions. the results of the simulation showed that with increase in moisture content o...
