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.

The study was conducted in three selected sites representing the soils of governorates central and northern Iraq (Salah al-Din, Kirkuk, Erbil), to determine effect morphological, physical chemical characteristics some soil genetic horizons on their spectral reflectivity using digital camera as well Knowing degree development classification according Quantitative (American) system for classifyin...

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...

Coastal habitats are interlinked by ecological connectivity, defined as the exchange of organic matter or organisms between habitats. The degree this connectivity will depend in particular on geometric properties landscape. increasing anthropogenic alterations estuaries therefore raises need to understand how their morphological characteristics influence fluxes We used stable isotopes investiga...

Nanocrystalline calcium phosphate apatites constitute the main inorganic part of hard tissues, and a growing focus is devoted to prepare synthetic analogs, so-called “biomimetic”, able to precisely mimic the morphological and physico-chemical features of biological apatite compounds. Both from fundamental and applied viewpoints, an accurate characterization of nanocrystalline apatites, includin...

Lead (Pb) is one of the most toxic metals in the environment and may cause drastic morphological and physiological deformities in Ipomoea lacunosa. The goal of this research was to evaluate some morphological and physiological responses of morning glory grown on a Pb- and chelate-amended soil. Soil samples were analyzed, at Mississippi State University Soil Laboratory, for physico-chemical para...

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...
