ITO thin ®lms (100±200 nm) are deposited on glass and plastic (PET and polycarbonate) substrates by r.f. sputtering. Process parameters such as oxygen partial pressure, r.f. power, and post deposition annealing parameters are varied to determine the dependence of the sheet resistance on process parameters. The microstructure of these thin ®lms is determined using an X-ray diffractometer (XRD) a...

In order to improve the accuracy of grain production forecasting, this study proposed a new combination forecasting model, the model combined stepwise regression method with RBF neural network by assigning proper weights using inverse variance method. By comparing different criteria, the result indicates that the combination forecasting model is superior to other models. The performance of the ...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

Loss of function mutations in waxy, encoding granule bound starch synthase (GBSS) that synthesizes amylose, results in starch granules containing mostly amylopectin. Low amylose grain with altered starch properties has increased usability for feed, food, and grain-based ethanol. In sorghum, two classes of waxy (wx) alleles had been characterized for absence or presence of GBSS: wx(a) (GBSS(-)) ...

Grain-boundary relaxation in nanocrystalline Fe was studied by high-resolution transmission electron microscopy HREM , and its effect on plasticity was characterized by nanoindentation. Samples with grain size of 9.8 nm were synthesized by mechanical attrition and subsequently annealed at low temperatures 80 and 100 °C without affecting the grain size. While the hardness is not significantly af...

The current study presents the results of a 13 week feeding study in rats with grain from Roundup Ready corn which is tolerant to the herbicide glyphosate. Herbicide tolerance was accomplished through the introduction of cp4 epsps coding sequences into the corn genome for in planta production of CP4 EPSPS enzymes. Unlike related corn EPSPS enzymes, CP4 EPSPS enzymes are not inhibited by the her...

Physical properties of grain dust derived from five grain types (soybean, rice, corn, wheat, and sorghum) were measured and reported. The grain dusts were obtained from dust collection systems of terminal grain handling facilities and were assumed to be representative of grain dust generated during the handling process. The physical properties reported were as follows: particle size distributio...

We present a new constraint on the amount of dust in the intergalactic medium (IGM) at high redshift. We derive the thermal history of the IGM by taking account of the photoelectric heating by dust grains, and compare it with the thermal history suggested by observations of Lyman α forests. As a result, if the IGM grain size is & 100 Å, the dust-gas mass ratio of the IGM at z & 2 is . 1/100 Gal...

The texture evolution accompanied by grain growth was investigated in a nanocrystalline Fe-78wt%Ni alloy, namely permalloy fabricated by using an electrodeposition method. The as-deposited specimen revealed a strong <100>//ND and a weak <111>//ND fibre-type textures. Grain growth took place during annealing beyond 370°C and resulted in the texture change such that the <111>//ND fibre strongly d...
