Aragonite, which is the polymorph of CaCO3 precipitated by modern corals during skeletal formation, has a higher solubility than the more stable polymorph calcite. This higher solubility may leave animals that produce aragonitic skeletons more vulnerable to anthropogenic ocean acidification. It is therefore important to determine whether scleractinian corals have the plasticity to adapt and pro...

increasing the water use efficiency in crop production is an important issue today. an experiment was conducted in 2009 in order to evaluate the corn reaction to partial root zone drying at fars province. treatments consisted of four irrigation levels (control, alternative furrow irrigation during whole season, alternative furrow irrigation until flowering then full irrigation and full irrigati...

agricultural activities have always been partly responsible for the emission of greenhouse gases and other environmental contaminants in the atmosphere. thus, studying on the environmental effects of agricultural activities and proposing appropriate strategies to mitigate these adverse effects can be paramount importance. in this study, in order to determine the environmental impacts of peanut ...

The stabilities of eight strains of respiratory syncytial virus were compared after the strains were freeze-dried in the presence and absence of the stabilizer SPGA, which contains 218 mM sucrose, 7.1 mM dipotassium hydrogen phosphate, 3.76 mM potassium dihydrogen phosphate, 4.9 mM sodium glutamate, and 1% (wt/vol) bovine albumin. Strains freeze-dried in the presence of SPGA showed only small-t...

Quantum mechanical electronic structure calculations are playing an increasingly useful role in many areas of mineralogy and geochemistry. This review introduces the density functional method for such calculations, gives an overview of the density functionals developed at the University of Minnesota, and summarizes selected applications using these density functionals that are relevant to miner...

Melon is a dessert loved by many, captivating with its thick aroma and delicate honey taste. The juicy, fragrant pulp not only delicious but also very useful for dietary purposes, therapeutic effect on diseases of the liver kidneys, anaemia, rheumatism cardiovascular disorders. This storehouse vitamins especially rich in potassium iron salts, pectins, fibre, easily digestible sugars, proteins, ...
