Chondrites, undifferentiated meteorites, have bulk chemistries similar to solar and preserve the history of the protoplanetary disk in their inclusions. The rarest subsets of chondrites with highest scientific value are only available for research in small aliquots. Minimally destructive techniques from sample collection to detailed chemical analysis are important for detailed understanding of ...

Wind-blown sand, or "saltation," is an important geological process, and the primary source of atmospheric mineral dust aerosols. Significant discrepancies exist between classical saltation theory and measurements. We show here that these discrepancies can be resolved by the inclusion of sand electrification in a physically based saltation model. Indeed, we find that electric forces enhance the...

Some of the major issues faced by the poultry industry are about; improving efficiency of production, reducing environmental pollution resulted from litter and reducing food cost. In general, to meet these challenges, series of attempts have been made by researchers. Some of them are inclusion of food additives to improve growth performance, reduction of specific nutrient concentration or manip...

from the last few years, the inclusion of microbial phytase in poultry diets has increased significantly, mainly in response to heightened concerns over phosphorus pollution of the environment and as cheaper means to make phosphorus available to birds from phytate. phytate is the major form of phosphorus, abundantly found in cereal grains, beans and oilseed meals used in poultry diet but the mo...

background: the refolding of proteins from inclusion bodies is affected by several factors, including solubilization of inclusion bodies by denaturants, removal of the denaturant, and assistance of refolding by small molecule additives. objectives: the purpose of this study was optimization of recombinant human interferon-b purification in order to achieve higher efficiency, yield, and a produc...

Several epidemiologic studies suggested that osteoporosis and osteoporotic fractures are not uncommon in South Korea. However, these previous cohort studies had limitations that may have influenced their results and the generalizability of the study conclusions, including small sample sizes, inclusion of only women, enrollment of participants from specific areas, and nonrandom selection of part...
