This paper by Lawson and coworkers reports very interesting results with regard to low molecular weight DOC (LMW-DOC) speciation and abundance in basal ice from glaciers that have different organic and lithological substrates and thermal regimes. The case is made that these LMW-DOC compounds may support and/or be a product of biogeochemical activity beneath glaciers with consequence to regional...
importance of sediment storage has been expressed as being higher than that of water in floodwater spreading networks. to determine the contribution of each geological formation in sediment input of gachsaran floodwater spreading station after 12 years of flood spreading, sediment sampling was conducted in 16 points and 0-15 cm depth of the field. using dry sieve analysis, all samples were anal...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
The intrusive bodies of Central Alborz, with display lithological composition, include olivine gabbro, olivine monzodiorite, olivine monzonite and pyroxene monzonite. They are accompanied by pyroclastic rocks of the Karaj Formation, and they occur as sill, lopolith, stock and plug. The essential minerals of these rocks are plagioclase, alkali feldspar, pyroxene, olivine and biotite. Mineral che...
abstract over the past two decades, applied linguists and language teachers have shown a great deal of interest in genre-centered approaches , mainly because of pedagogic concerns . this has been due to the need to help non-native readers enhance their ability to understand academic and scientific texts. following swales’ (1981) works on genre analysis, studies of different sections of resear...
enhancement of jahani (firouzabad) salt dome lithological units, using principal components analysis
in this study, principal components analysis was used to investigate lithological characteristics of jahani salt dome, firouzabad. the spectral curves of rocks in the study area show that the evaporate rocks have the highest reflectance at specified wavelengths. the highest reflection has been seen in gypsum and white salt, while minimal reflection can be observed in the igneous rocks from the ...
The purpose of this paper is to assess the efficacy of green coffee extract (GCE) as a weight loss supplement, using data from human clinical trials. Electronic and nonelectronic searches were conducted to identify relevant articles, with no restrictions in time or language. Two independent reviewers extracted the data and assessed the methodological quality of included studies. Five eligible t...
The aim of the study was to determine whether children with chronic benign pain are in contact with their general practitioner (GP) more frequently than those without chronic benign pain. A random sample of children and adolescents aged between 0 and 18 years of age was drawn from the records of ten general practices. According to their responses to a pain questionnaire, subjects were assigned ...
