Our study aims to clarify the population nutrient status in locations with different levels of iodine in the water in China; to choose effective measurements of water improvement(finding other drinking water source of iodine not excess) or non-iodised salt supply or combinations thereof; to classify the areas of elevated water iodine levels and the areas with endemic goiter; and to evaluate the...

The enthalpically favoured hydration of hydrophobic entities, termed hydrophobic hydration, impacts the phase behaviour of numerous amphiphiles in water. Here, we show experimental evidence that hydrophobic hydration is strongly determined by the mean energetics of the aqueous medium. We investigate the aggregation and collapse of an amphiphilic polymer, poly-N-isopropyl acrylamide (PNiPAM), in...

The vibrational dynamics of vacuum-isolated hydrogen-bonded complexes between water and the two simplest alcohols is characterized at low temperatures by Raman and FTIR spectroscopy. Conformational preferences during adaptive aggregation, relative donor/acceptor strengths, weak secondary hydrogen bonding, tunneling processes in acceptor lone pair switching, and thermodynamic anomalies are eluci...

Public concern over events of manganese-discolored drinking water and the potential for adverse health effects from exposure to excess manganese reached a high level in 2005. In response, Public Health Madison Dane County, together with the Madison Water Utility, conceived and implemented a public health/water utility strategy to quantify the extent of the manganese problem, determine the poten...

IN performing this test Knoop [1908] adds bromine water to the solution to be tested until there is just a very slight excess. On heating, the excess bromine disappears and in the presence of histidine a brownish red colour is developed; if the latter is in sufficient concentration a dark precipitate settles out. The solution to be tested should be slightly acid. The only substance other than h...

virtual water trade is investigated in industrial, agricultural, social sectors for national and global scales. in this study, interbrain virtual water was evaluated in irrigation sector for the sefidroud basin to use in the allocation of water resources. in this regard, through investigating eight cropping pattern (s1- s8) in the riverbank of qezelozan river (provinces of east azarbaijan, zanj...

BACKGROUND Although several reports concerning the association of iodine excess and thyroid disease have appeared, no systematic review of the association between iodine excess intake and thyroid diseases, especially hyperthyroidism and hypothyroidism, has yet been reported. METHOD We conducted a systematic search of Ovid MEDLINE, PubMed, Cochrane Central Register of Controlled Trials databas...

an important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. by enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. this enhancement is achieved through the use of achiral plasmoni...
