Quantitative Structure-Property Relationships (QSPR) are predictive methods of macroscopic properties of substances based on their only molecular structures. If these methods were initially mainly devoted to biology and toxicology, they are nowadays increasingly used for the prediction of physico-chemical properties. In the framework of the European REACH regulation (2006), their developments a...

UNLABELLED Physico-chemical properties of amino acids can be used to study protein sequence profiles, folding and function. We collated 242 properties for the 20 naturally occurring amino acids and created a dataset. The dataset is available as a database named APDbase( Amino acid Physico-chemical properties Data base). The database can be queried using either key words describing physico-chemi...

By the consideration of the microscopic picture of activated sludge samples it is possible to introduce a further biological parameter apart from the conventional physico-chemical parameters for the evaluation and control of biological stages of waste water treatment plants. It is reported that different parameters have certain influences on the activated sludge floc and on the developing bioze...

in this research, the physico-chemical water quality parameters and the effect of climate changes onwater quality is evaluated. during the observation period (5 months) physico-chemical parameterssuch as water temperature, turbidity, saturated oxygen, dissolved oxygen, ph, chlorophyll-a, salinity,conductivity, and concentration of total nitrogen (nutrient level) as main pollutant factor have be...

the river kabini which is tributary of cauvery drains through industrial area at nanjangud, karnataka. out of the sediment load carried by the river, 2micron the clay fraction was analyzed for total heavy metal contents and advanced statistical techniques such as cluster analysis and correlation matrix were applied in order to investigate the source of heavy metal concentration in the sediments...

the genus azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics, and warm temperate regions of africa, asia, and america. for several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. hg, pb, cr and cd) through wastewater treatment or for elimination of...

guar gum and whey proteins concentrate (wpc-35) were used as functional additives to improve the functional characteristics (hardness and meltability) of the na-caseinate-based imitation cheese. also, the alterations in the composition, sensory acceptance, color, and texture caused by these ingredients were evaluated. imitation cheeses were formulated with three levels each of wpc (0, 1.5, and ...
