The Elimination of Grains and Grain Boundaries in Grain Growth

Interface Science, 1997
The topological changes that occur during coarsening of 2D and 3Dcellular structures, such as polycrystals, areinvestigated. Particular attention is given to the elimination ofgrain boundaries and grains with more than the minimum number oftopological elements.

Coagulation of grains and gas-grain interactions

Advances in Space Research, 1995
Three-dimensional off-lattice Monte Carlo simulations have been used to simulate the production of interstellar dust analogues on the computer. At first, the two rather well known extreme cases of ballistic growth, i.e. particle-cluster (BPCA) and cluster-cluster aggregation (BCCA) were investigated.

Metabolites of Lesser Grain Borer in Grains

Journal of Agricultural and Food Chemistry, 2004
Many volatile alcohol and ester metabolites of the lesser grain borer (LGB, Rhyzopertha dominica) cultured on wheat grain were identified. Volatiles from infested samples at 80 degrees C were collected on Tenax absorbent, thermally desorbed, and analyzed by gas chromatography (GC) using infrared (IR) and mass (MS) detectors for component identification.

Contaminants of Grain

2004
Grain for processing should be clean and free of contaminants, but realistically, there may be many nongrain materials present. These materials cover a wide range: seeds of other crops and of weeds, insects and animal products, infected and defective grains, agricultural chemicals, and tainting substances.

GRAIN AND GRAIN STRUCTURE

American Journal of Applied Science and Technology
High-quality grain cultivation, complete organization of conditions for its collection and storage, break-even liquidation of grain harvest create prerequisites for the growth of the economy of processing enterprises.

3DXRD: Grain Maps, Grain Dynamics and Grain Refinements

Crystallography Reviews, 2004
The three-dimensional X-ray diffraction (3DXRD) method is reviewed. The method is based on the use of high-energy X-rays from synchrotron sources and a ‘tomographic’ approach to diffraction. With 3DXRD the structure of the embedded grains within polycrystals or powders can be characterised non-destructively within millimetre to centimetre size ...

Grain-Grain Coagulation in the ISM

EAS Publications Series, 2002
We have developed a dust emission model in order to reproduce the evolution of the far-infrared (FIR) to sub-millimetre (sub-mm) dust emission properties which is observed in the transition between the diffuse and the dense interstellar medium (ISM). We propose that the coagulation of grains into fluffy aggregates could be the process responsible for ...

Whole grains, refined grains and fortified refined grains: What’s the difference?

Asia Pacific Journal of Clinical Nutrition, 2000
Dietary guidance universally supports the importance of grains in the diet. The United States Department of Agriculture pyramid suggests that Americans consume from six to 11 servings of grains per day, with three of these servings being whole grain products. Whole grain contains the bran, germ and endosperm, while refined grain includes only endosperm.

Against the grain

Science, 2017
Forest scientist Jerry Franklin became known for helping protect old-growth trees from logging. Now, he's arguing for letting the chainsaws loose in some forests.
