One way of generating light weight composites is to insert porous ceramic grains into the melt of the matrix. The foam like inner structure of the grains causes a considerable weight reduction. On the other hand, it is desired that the mechanical properties of the matrix carry over to the composite. The properties of the composite depend both on the structure of grains as well as on their distr...

Previous studies have shown that in vitro thyroid peroxidase (TPO) iodide oxidation activity is decreased and thyroid T4-5'-deiodinase activity is increased 15 days after induction of experimental diabetes mellitus (DM). In the present study we used thyroid histoautoradiography, an indirect assay of in vivo TPO activity, to determine the possible parallelism between the in vitro and in vivo cha...

a field study was conducted at the college of agriculture, shiraz university, shiraz, iran to evaluate the effect of different crop residue and nitrogen rates on yield and yield components of two dryland wheat (triticum aestivum l.) cultivars. the experiment was conducted as a strip split plot with four replications. vertical plots included two dryland current wheat cultivars (azar2 and nicknej...

Twenty available genotypes of maize were screened for resistance to Chilo partellus in the field. The genotype Sahiwal 2002 was found to be most susceptible while DK-6525 was most resistant. Maximum infestation was observed at the end of April while the minimum in the last week of March. Significant variations were observed in all the plant characters viz., number of nodes per plant, plant heig...

studies on manipulating the source-sink relationships during postanthesis in wheat have shown inconsistent results, concluding that wheat yield could be either sink- or source-limited. most studies have reported data of grain mass as an average of all grains preventing the recognition of different sensitivities to the availability of assimilates of grains placed at different positions within th...

Copper bonding wires were characterized using electron backscatter diffraction (EBSD). During drawing, shear components are mainly located under the surface and ,111. and ,100. fiber texture components develop with similar volume fractions. Grain average misorientation (GAM) and scalar orientation spread (SOS) of the ,100. component are lower than those of the ,111. or other orientations. Also,...

Meteorological factors are one of the important that determine maize kernel weight and grain nutritional quality. Analyzing influence meteorological before after anthesis on quality components is great significance for improving corn yield Therefore, five different hybrids conducted continuous experiments from 2018 to 2021 were selected in this study, explore response growth periods, quantify l...
