Brasica napus L. is one of the most important crops in the world, but every year during mechanized harvesting with conventional combines large quantities of the seeds fall to the ground and thus result in a decrease in yield. Therefore, designing and manufacturing a head specific for harvesting this crop is a high priority. In this study, the head of a combine for harvesting fine-grained produc...

OBJECTIVE The objective of this study was to provide national estimates of whole-grain intake in the United States, identify major dietary sources of whole grains and compare food and nutrient intakes of whole-grain consumers and nonconsumers. METHODS Data were collected from 9,323 individuals age 20 years and older in USDA's 1994-96 Continuing Survey of Food Intakes by Individuals through in...

Data from USDA-coordinated winter wheat (Triticum aestivum L.) regional performance nurseries collected over the time period 1959 to 2008 were used to estimate genetic gain (loss) in grain yield, grain volume weight, days to heading, and plant height in winter wheats adapted to the Great Plains of North America. In both the Southern Regional (SRPN) and Northern Regional Performance Nurseries (N...

The purpose of this study was to establish food ingestion factors needed to assess exposure to contaminants through food ingestion. The study reclassified the raw data of the Korean National Health and Nutrition Examination Survey in 2001 into 12 subcategories including grain products, meat products, fish and shellfish, and vegetables for international comparability of exposure evaluation. The ...

In glacial environments particle-size analysis of moraines provides insights into clast origin, transport history, depositional mechanism and processes of reworking. Traditional methods for grain-size classification are labour-intensive, physically intrusive and are limited to patch-scale (1m) observation. We develop emerging, high-resolution groundand unmanned aerial vehicle-based ‘Structure-f...

Cooperative business relationships are dramatically changing the structure of the North American agri-food sector. An examination of recent events in the grain industry reveals the extent to which cooperative ventures are becoming integrated into international agribusiness. When Cargill decided to expand its presence in Canada it participated in several joint ventures, one with Hazzard Farm Ser...

in this work the synthesization process of nanocrstallite nd:ktp powders by modified pechini methodwas studied. the results of xrd studies indicate that ktp nanocrystallites doped by nd has orthorhombicphase. the structural and lattice modes of the synthesized nanocrystallite products were investigated byusing micro raman back scattering and ft-ir transmission spectroscopies. sem imaging techni...

A stream of wheat, projected into still air by rapidly moving belts, is dispersed by the conlbined effects of air drag and gravitation into numerous fractions which are caught in a series of hoppers....

Since no comparative advantage analysis system developed for agricultural products in China counties, this paper discussed how to use comparative advantage theory and Java language to design regional main grain comparative advantage analysis system. The system applies comparative advantage index calculation method to rapidly provide users with relevant data and analysis of grain production comp...

Beauveria bassiana (Balsamo) Vuillemin was tested under maximum challenge conditions with an estimated dose of 1.1 × 10 5 conidia/mm 2 for its effects on eggs of four of the major beetle pests of stored grain and grain products. When ambient relative humidity (RH) was 92%, hatch of fungus-treated Rhyzopertha dominica (Fabricius) eggs was 13% versus 58% for control eggs, and hatch of treated Tri...
