Aerosols are known to influence significantly the radiative budget of the Earth. Although the direct effect (whereby aerosols scatter and absorb solar and thermal infrared radiation) has a large perturbing influence on the radiation budget, the indirect effect (whereby aerosols modify the microphysical and hence the radiative properties and amounts of clouds) poses a greater challenge to climat...

In this study, the ecological parameters of the effluent obtained from dyeing of scoured and mercerised organic cotton single jersey fabrics with textile reactive dyes adopting exhaust dyeing method was investigated. The dyes used include regular (Navacron H and FN) reactive dyes and low impact (Remazol and Levafix) reactive dyes along with inorganic salt (sodium sulphate) and biosalt (trisodiu...

Gustatory differences in Phenylthiocarbamide (PTC) tasters and non-tasters were studied in hypothyroid and hyperthyroid subjects. After presenting for PTC sensitivity, gustatory responses to 7 dilutions of test solutions for glucose (sweet), sodium chloride (salt), citric acid (sour) and quinine sulphate (bitter) were studied in PTC tasters and non-tasters. The intensity and pleasantness respon...

The phase transitions and hygroscopic growth of two humic acid aerosols (Aldrich sodium salt and Leonardite Standard (IHSS)) and their mixtures with ammonium sulphate have been investigated using a combination of two techniques, Fourier transform infra-red (FTIR) spectroscopy and tandem differential mobility analysis (TDMA). A growth factor of 1.16 at 85% relative humidity (RH ) was found for t...

BACKGROUND While it is well known that hypotonic solutions of sodium chloride induce hemolysis, the effects of other salt solutions on human erythrocytes have not been well documented. OBJECTIVE The study is to compare the effects of other salt solutions on human red cells. METHODS Iso-osmotic and hypo-osmotic solutions of various salts were prepared after taking into account their molecula...

a study was made on the interaction between histon h1 and sodium n-dodecyl sulphate (sds) in the presence of sodium arsenate inside a phosphate buffer of ph 6.4, using spectroscopy and equilibrium dialysis at 27 °c. the binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the wyman binding potential. the binding data hs been analysed in terms of hi...

In study, spherical Silver nanoparticles (SNPs) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. In this experimental work, SNPs are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of SNPs have been observed. Further anti...
