An assortment of 10 winter wheat cultivars was tested for specific effects on weed suppression.Furthermore cultivar specific effects of weed infestation and weed control measures on the crop yield were investigated.Two trial series conducted from 2005 to 2010 demonstrated a wide cultivar specific range Subwoofer Enclosure of shading capacity and we
High-entropy alloys (HEAs) were fabricated by powder metallurgy using gas-atomized powder and spark Shoes plasma sintering (SPS) followed by surface modification (plasma nitriding) of the sintered sample.Plasma nitriding forms nitride and induces solid-soluting of N; it enables the diffusion of N atoms by removing the passive film formed on the sur
Dissimilar CuNiCrSi and CuCrZr butt joints were successfully frictionstirwelded at constant welding speed of 150 mm/min and rotational speed of 1400 rpm with the CuCrZr alloy or the CuNiCrSi alloy located on the advancing side (AS).The microstructure and mechanical properties of joints were investigated.When the CuCrZr alloy was located on the AS,
Introduction: There is the obscurity of published data on surgical management of external abdominal wall hernias in our environment.This study was, therefore, to describe the pattern, outcome, and experience in the surgical management of anterior abdominal wall hernias in Shisong, Cameroon.Methods: This was a descriptive retrospective study conduct
