in order to optimize use of water resources with selection of suitable wheat genotype(s) and irrigation schedule, in this experiment, the effect of elimination of irrigation at terminal growth and development stages of five wheat genotypes was investigated in two successive growing seasons (2002-03 and 2003-04) in the agricultural research station of torogh mashhad. split plot experiments were ...

Cereal Chem. 79(6):885-89\ For 30 yean,. near-infrared (NIR) spectrmcopy has routinely heen applied to the cereal grains for the purpose of rapidly measuring concentrations of constituents such as protein and moisture. The research descrihed herein examined the ability of NIR reflectance spectroscopy on harvested \!; heat to determine weather-related, quality-determining properties that occurre...

The consumer quality of baked products is closely related with dough structure properties. These are developed during dough fermentation and finalized during its baking. In this study, magnetic resonance microscopy (MRM) was employed in a study of dough fermentation and baking. A small hot air oven was installed inside a 2.35-T horizontal bore superconducting magnet. Four different samples of c...

In this data article, laboratory experimental investigation results carried out at National Centre for Agricultural Mechanization (NCAM) on moisture content, machine speed, die diameter of the rig, and the outputs (hardness, durability, bulk density, and unit density of the pellets) at different levels of cassava pellets were observed. Analysis of variance using randomized complete block design...

Spark plasma sintering (SPS) has been employed to consolidate a micron-sized zirconium carbide (ZrC) powder. ZrC pellets with a variety of relative densities are obtained under different processing parameters. The densification kinetics of ZrC powders subjected to conventional hot pressing and SPS are comparatively studied by applying similar heating and loading profiles. Due to the lack of ele...

Wheat flour is a commodity with a high risk of Aflatoxins (AFs) contamination. During the bread making there are many processes that can affect the AFs stability. The effect of bread making process using different yeast types on AFs levels was investigated. For this purpose, standards of AFs including B and G were added to flour and then bread loaves were prepared. Three types of commercially a...

The effect of the dosing vehicle (e.g., dough) on the ability of an in vitro gastrointestinal (IVG) method to predict relative bioavailable Pb associated with soil ingestion was evaluated. Bioaccessible Pb determined by the IVG method was compared with relative bioavailable Pb measured from dosing trials using juvenile swine for 18 contaminated soils ranging from 1270 to 14200 mg Pb kg(-1). Bio...

How infectious a person is when infected with HIV depends on what stage of the disease the person is in. We use 3 stages, which we call primary, asymptomatic, and symptomatic. It is important to have a systematic method for computing all 3 infectivities so that the measurements are comparable. Using robust modeling, we provide high-resolution estimates of semen infectivity by HIV disease stage....
