the purpose of this study was comparison of applicability of tertiary treatment of tehran domestic sewage with organic and inorganic coagulants or a combination of them. the far test procedure was applied utilizing: alum, polyelectrolyte wt 2600, anionic polyelectorlyte wt 3000, and nonionic polyelctrolyte wt 2690 as organic coagulants (products of calgon). the combination of lime with each of ...
Physico-chemical profiling is a fundamental tool at the early stage of drug discovery in screening drug-like candidates. Complex physico-chemical profiling, including molecular properties such as solubility, ionization, lipophilicity and permeability, has been found to be of predictive power in ADME (absorption, distribution, metabolism, elimination). In the present thesis work, the physico-che...
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...
Physico-chemical properties reflect the functional and structural characteristics of a protein. The comparative study of the physicochemical properties is important to know role of a protein in exploring its molecular evolution. A number of online and offline tools are available for calculating the physico-chemical properties of a single protein sequence. However, a tool is not available for a ...
slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...
long term monitoring programme on brine shrimp ( artemia sp.) is being carried out by the environment agency, abu dhabi, united arab emirates (ead) with the prime purpose of understanding the population dynamics, ecology and habitat requirements of artemia at al wathba lake, situated within al wathba wetland reserve, which is an artificial wetland near abu dhabi city. the present study, being a...
The objective of this paper deal with the physico chemical aspects of certain colouring plants namely. Bixa orellana Linn. (Leaves) and Lawsonia inermis Linn (Leaves). The determined data under the physico chemical, chromatographic and spectrophotometric studies can be taken as a pharmacopoeial standards.
Present work focused on the seasonal variations in the physico-chemical parameters of the freshwater temple pondPrayagtirth at Trimbakeshwar in Nashik district during summer, monsoon and winter. A total 15 parameters were analysed and their seasonal variation is discussed. The correlation matrix of the various physico-chemical parameters are computed and analysed.
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...
In the course of screening for new antitumor substances, BE-18591 (la) was isolated from cultures of Streptomyces sp. BA18591X). The isolation and physico-chemical properties together with biological activities are reported in the preceding paper. In this paper, the structure elucidation is described. The physico-chemical properties of la were summarized in a previous paper1*. The molecular for...
