Temperate and dry deciduous forest covers major portion of terrestrial ecosystem in India. The two forest types with different dominant tree species differ in litter quality and root exudates, thereby exerting species-specific impact on soil properties and microbial activity. This study aims to examine the influence of forest type or dominant tree species on soil physico-chemical properties and...

Some studies have demonstrated that in vivo degradation processes are influenced by the material's physico-chemical properties. The present study compares two hydroxyapatites manufactured on an industrial scale, deproteinized at low and high temperatures, and how physico-chemical properties can influence the mineral degradation process of material performance in bone biopsies retrieved six mont...

introduction: resin composites are an important part of restorative treatment in modern dentistry. there are many trademarks available in iran market and physico-chemical properties of many of these resin composites are not evaluated yet. this study was carried out to evaluate the physico-chemical properties of four available resin composites and also to assess the effect of aging on their prop...

background: although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. it is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. the purpose of this study has been to investigate the level of physicians' knowledge about r...

Uranium concentration in forty-six groundwater samples collected from the region near uranium deposits Royal village of Sikar district, Rajasthan, is determined using LED fluorimetry technique. Age-dependent annual effective dose, radiological, and chemical toxicity risks are calculated to assess health associated with for people living nearby area. concentrations different vary 4.79–266.28 µg/...

From a molecule to the brain perception, olfaction is a complex phenomenon that remains to be fully understood in neuroscience. Latest studies reveal that the physico-chemical properties of volatile molecules can partly explain the odor perception. Neuroscientists are then looking for new hypotheses to guide their research: physico-chemical descriptors distinguishing a subset of perceived odors...

The syntheses and the structural, spectroscopic, and chemical properties of phosphirenes, phosphirene-transition metal complexes, and silirenes are discussed and compared. Close analogies are noted in the synthetic schemes and physico-chemical properties of the two types of three-membered rings.

Physico-chemical properties, molecular interactions and thermodynamic stability of human and bovine serum albumins in complexes with mitomycin C were investigated. The pH and temperature influence on serum albumins properties and the binding mechanism of mitomycin C to these proteins have been monitored by spectrometry and spectrofluorimetry methods.

Leucinostatin, a peptide antibiotic, was separated by silica gel and alumina column chromatography into two related components designated as leucinostatin A hydrochloride (C61H111-N11O13.HCl) and leucinostatin B hydrochloride (C61H109N11O13.HCl). Physico-chemical as well as biological properties of the two separated components were analyzed. These properties pointed to closely resembling chemic...

Morphological and physiological characteristics of biological soil crusts (BSCs) enhance soil stability and fertility, and influence soil chemistry. However, the effect of BSCs on soil physico-chemical properties may vary depending on taxa (cyanobacteria, lichen, bryophytes) and species, and be susceptible to soil surface disturbance. We examined a wide variety of soil physico-chemical properti...
