Anthracnose caused by Colletotrichum gloeosporioides Penz.) Penz. and Sacc. is one of the most important diseases of mango. The nutritional studies were taken up to know the best source of carbon and nitrogen required for the growth and sporulation of the fungus. The study indicated that out of six different carbon sources tried, mannitol was found to be the best source of carbon for the growth...

Nanoparticles of potassium tantalate (KTaO3) and potassium niobate (KNbO3) were synthesized by oxidation of metallic tantalum in molten potassium nitrate with the addition of potassium hydroxide. Magnetization curves obtained on these ferroelectric nanoparticles exhibit a weak ferromagnetism, while these compounds are nonmagnetic in a bulk. The experimental data are used as a start point for th...

To determine the efficacy of a cosmetic aluminium lactate/potassium nitrate/hydroxylapatite toothpaste for reduction dentine hypersensitivity (DH) pain as compared to control containing potassium nitrate. The study was randomised, examiner-blind, two treatment arm, parallel controlled trial in healthy adults with at least 2 sensitive teeth (Schiff >2). At baseline, immediately after and 7 14 da...

Seedlings of Arabidopsis thaliana, Columbia ecotype, were used in vitro to analyze root hair growth response to inoculation by the plant-growth-promoting rhizobacterium, Azospirillum brasilense Sp-245. Root hair length was measured at physiologically-identical stages of root growth. In seedlings inoculated with A. brasilense, root hairs were more than twice the length of those of the non-inocul...

In China, excessive use of nitrogen fertilizers in glasshouses leads to nitrate accumulations in soil and plants, which then limits productivity. Melatonin, an evolutionarily highly conserved molecule, has a wide range of functions in plants. We analyzed the effects of melatonin pretreatment on the growth, mineral nutrition, and nitrogen metabolism in cucumber (Cucumis sativus L. "Jin You No. 1...

Southwest Florida is one of the most rapidly growing regions United States and has been impacted over past decade with water-quality issues some associated health problems. The ionic ratios dust measured in southwest vary significantly from those on east coast Caribbean. metals concentrations reported herein are enriched potassium calcium local sources. Atmospheric deposition nutrients appears ...

If a sartorius muscle of frog is pretreated for 30 min. with a hyposmotic Ringer's (called "hyposmotic potassium chloride") in which all sodium chloride is replaced by 23 mM potassium chloride, and then is immersed in normal Ringer's for about 40 min., a twitch of normal size can be elicited although the potassium contracture is almost completely abolished. During the time that this selective i...

Nitrate is a wide spread contaminant of ground and surface water. The source of nitrate in the ground water may be from run off or seepage from fertilized soil, municipal or industrial waste water, land fills, septic system, urban drainage or decaying plants. Human and animal systems are affected severely on nitrate exposure. The study was to investigate the effect of dietary nitrate exposure o...
