Sringa Bhasma is an Ayurvedic medicine prescribed mainly for asthma. Physico chemical studies and thin layer chromatography for this medicine was worked out to laydown standards. The evolved parameters can be used for prescribing dependable standards to this medicine.

Laboratory studies were conducted to investigate scrap-tire-shreds as a potential alternative to conventional gravel in the drainage layer of leachate collection system at the base of landfill. Performance of various physico-chemical characteristics of leachate after passing it through combined bed of scrap-tire-shreds and gravel for different combinations of thickness of scrap-tireshreds and g...

Many pharmaceutical products find their way into receiving waters, giving rise to concerns regarding their environmental impact. A procedure was proposed that enables ranking of the hazard to aquatic species and human health due to such products. In the procedure, hazard assessment is based on five of the pharmaceutical product's individual physico-chemical properties. These properties are aggr...

Proteochemometrics is a technology for the study of molecular recognition based on chemometric techniques. Here we applied it to analyse the amino acids and amino acid physico-chemical properties that are involved in antibodies' recognition of peptide antigens. To this end, we used a study system comprised by a diverse single chain antibody library derived from the murine mAb anti-p24 (HIV-1) a...

Guduchi Satva (GS), the starchy material extracted from the Guduchi stem is well-known Ayurvedic single drug formulation having a wide range of therapeutic utility. Species of the plant, stem size, collection time, season and maturity of the plant may affect the yield and physico-chemical profile of GS. However, published data on such variations is lacking. Considering this, present study is pl...

The standard genetic code is known to be much more efficient in minimizing adverse effects of misreading errors and one-point mutations in comparison with a random code having the same structure, i.e. the same number of codons coding for each particular amino acid. We study the inverse problem, how the code structure affects the optimal physico-chemical parameters of amino acids ensuring the hi...

Aquatic biodiversity is one of the most essential characteristics of the aquatic ecosystem formaintaining its stability and a means of coping with any environmental change. The entire stretch of the Mothronwala swamp has rich riparian vegetation for providing conducive environment for the growth of aquatic organisms. The present work has been undertaken to study the bio-physico-chemical charact...

Acoustic measurements provide convenient non-invasive means for the characterisation of materials. We show here for the first time how a commercial impedance tube can be used to provide accurate measurements of the velocity and attenuation of acoustic waves in liquid foams, as well as their effective "acoustic" density, over the 0.5-6kHz frequency range. We demonstrate this using two types of l...

Odours are highly complex, relying on hundreds of receptors, and people are known to disagree in their linguistic descriptions of smells. It is partly due to these facts that, it is very hard to map the domain of odour molecules or their structure to that of perceptual representations, a problem that has been referred to as the Structure-Odour-Relationship. We collected a number of diverse open...

ar from being the atheist that some have portrayed, Thomas Paine was a “scientific deist” who believed that the omnipotence and benevolence of God are evident in the structure of the universe. The epigraph above is one of his most elegant expressions of this view. What is more surprising than Paine’s reverence is that The Age of Reason (1794–95) appears to owe much to a tradition of Christian a...
