Small superconducting grains are discussed in the frameworks of both the reduced BCS Hamiltonian and the Universal Hamiltonian. It is shown that fluctuations of electrons in levels far from the Fermi energy dominate superconducting properties in small and ultrasmall grains. Experimental consequences related to the spin susceptibility and persistent currents of grains and rings with weak electro...

Introduction: It is generally accepted that in addition to igneous olivine grains, chondrules contain relict olivine grains that did not crystallize in situ [e.g., 1]. Chondrule melts cooled relatively fast [e.g., 2], which aided in the preservation of relict grains. One type of relict olivine grain, found both inside chondrules and as isolated olivine grains outside chondrules, and found both ...

Currently, an estimated 32.9% of American adults are overweight, 34.3% are obese, and 5.9% are extremely obese (38). In fact, adults defined as being normal weight, i.e., those whose body mass index (BMI) falls in the range of 18.5 to 24.9 kg/m2, are a minority within the U.S. population. Coupled with declines in physical activity, overconsumption of calorie-rich, nutrient-poor foods is contrib...

BACKGROUND Studies of whole grain and chronic disease have often included bran-enriched foods and other ingredients that do not meet the current definition of whole grains. Therefore, we assessed the literature to test whether whole grains alone had benefits on these diseases. OBJECTIVE The objective was to assess the contribution of bran or cereal fiber on the impact of whole grains on the r...

In the search for aqueous habitats on Mars direct proof of (ancient) flowing water is still lacking, although remote sensing has provided indications of young fluvial systems. To demonstrate that such proof can be given, we examined surface marks on recent terrestrial sand grains by atomic force microscopy (AFM) and applied a quantitative three-dimensional analysis that can numerically distingu...

in order to evaluate the relationship between morphological characters in rice lines two populations at f3 generation were grown in research field of agricultural sciences and natural resource university, sari, iran, during 2012. statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...

Distillers grains are co-products produced from the fermentation of grains for alcohol. Traditionally, alcohol was produced mainly for the beverage liquor industry, but in the last 20 years its use as an alternative fuel has increased significantly. This increased demand has led to the development of several ethanol production plants in Minnesota and the surrounding area. In 1996, it is estimat...
