the oil extracted from three major canola cultivars (hyolla401, hyolla420 and rgs003) grown in golestan province was analyzed for physico-chemical properties, fatty acid composition, minerals content, and stability during 16 weeks of storage. according to the results, the highest iodine value and refractive index belonged to hyolla401. the highest saponification value was observed in hyolla420....

in this study, micromorphological properties of some samples collected from pedons polluted with petroleum refinery wastes and some adjacent unpolluted pedons were studied. after description of the studied pedons, disturbed and undisturbed samples were collected for physicochemical and micromorphological analyses. the results showed that the physicochemical properties (i.e. structure, bulk dens...

present communication deals with the study of four village fish culture ponds (two wild and two managed ponds) from district hisar of haryana, india was undertaken, to correlate the water quality and biological cycles in ponds with fish production. studies have revealed that the ponds are in good trophic status. chlorides, total hardness, calcium, magnesium, biochemical oxygen demand (bod), pho...

This work concerns the search for new ways to modify surface of biomedical Ti–13Zr–13Nb alloy applications in regenerative medicine and personalized medicine. Obtained first time, oxide nanotubes (ONTs) layers first-generation (1G) on a were produced by anodizing 0.5% HF electrolyte at 20 V 120 min. The physico-chemical characterization obtained bamboo-inspired 1G ONTs was conducted using TEM A...

How do physico-chemical stimulus features, perception, and physiology relate? Given the multi-layered and parallel architecture of brains, the question specifically is where physiological activity patterns correspond to stimulus features and/or perception. Perceived distances between six odour pairs are defined behaviourally from four independent odour recognition tasks. We find that, in regist...

The effect of artificial pozzolan (waste brick) on the physico-chemical properties of cement manufactured was investigated. The waste brick is generated by the manufacture of bricks. It was used in the proportions of 0%, 5%, 10%, 15% and 20% by mass of cement to study its effect on the physico-chemical properties of cement incorporating artificial pozzolan. The physicochemical properties of cem...

Physico-chemical properties of Aspergillus conidia rely on their outer cell-wall rodlet layer. In A. fumigatus and A. nidulans, the rodlet structure is due to an hydrophobin encoded by homologous rodA genes. To evaluate the role of the rodlet structure on the physico-chemical properties of conidia, we compared hydrophobicity, Lewis acid-base (i.e. electron donor/acceptor) characteristics and el...

In this study, the physical, morphological, mechanical and thermal properties of furfuryl alcohol/2-ethylhexyl methacrylate/halloysite nanoclay wood polymer nanocomposites (FA-co-EHMA-HNC WPNCs) were investigated. FA-co-EHMA-HNC WPNCs were prepared via an impregnation method and the properties of the nanocomposites were characterized through the weight percent gain, Fourier transform infrared (...

Objective: To investigate the cytomorphological and physico-chemical characteristics of Sida rhombifolia. Methods: Fresh leaves, stems and roots were studied for microscopical characters and dried powder of leaves, stems and roots were subjected to physico-chemical analysis using standard methods. Results: The detail microscopy of leaf revealed the presence of paracytic stomata, unicellular cov...
