Raman spectroscopy has become one of the most important vibrational analytical techniques for the investigation of paint samples and notably for organic pigments. For the analysis of modern materials, especially for synthetic inorganic and organic pigments the prospect of using Raman spectroscopy is an alternative to e.g. Py-GC-MS. It provides enough information allowing for a broad characteriz...

A. Research Objective The overarching goal of the proposed research is to develop a comprehensive data and mechanistic knowledge base with respect to the binding and sequestration reactions of organic DNAPL components and heavy metals with different types of soil matrices. A principal ultimate use of this knowledge and information base will be its application as a platform for designing specifi...

exploitation of wild relatives of crop plants to a large extent depends on the efficient use of germplasm resources available in natural habitat and the centre of diversity. the mulberry, sole food for silkworm is cultivated for the production and development of silkworm industry. four species of mulberry viz., m. indica l., m. alba l., m. laevigata wall., and m. serrata roxb., are reported in ...

persian gazelle, gazella subgutturosa, exists throughout arid and semiarid regions of iran and has a key role in these frail ecosystems. habitat degradation and population decline has placed it on the list of vulnerable species in 2008. the phylogenetic relationships of three persian gazelle populations in the central part of iran (i.e. ghamishlou national park and wildlife refuge, mouteh wildl...

this study was performed  in second half of year 2009.for bird counting , monthly from septamber until march 2009. total counted birds in maroon lake were (971). maximum number of counted birds was in february  (191) and minimum of counted was in septamber (95). total counted birds in jaizan were (385. maximum number of the counted bird was in february (84) and minimum of counted (52) was in ja...

soil conservation is one of the most important regulative functions of natural ecosystems. this function is of high importance in taleghan watershed due to high erosion quantity and sediment accumulation in taleghan dam reservoir. soil loss reduction, sedimentation control and fertility conservation were considered as different aspects of soil conservation. effect of land use and vegetation cov...

this paper discusses the study of community’s preferences for biodiversity conservation management institution which may motivate them to support conservation efforts in the okwangwo division of the cross river national park, nigeria. the empirical data was generated from personal interviews and factors influencing the respondents’ choice were examined with the aid of multinomial logit mode...

in this paper, we report an investigation of changes in land use and ecosystem services on loess plateau in northern shaanxi province from 1978 to 2004. we used three landsat tm and/or etm data sets to estimate changes in the size of five land-cover/land-use categories, and we also used previously published value coefficients to estimate changes in the value of ecosystem services delivered by e...
