biotite samples from different units of boroujerd granitoid complex (bgc) of the sanandaj-sirjan zone, western iran, have beenanalyzed by electron microprobe for major elements. biotite analyses from three units of quartzdiorite, granodiorite and monzograniteof bgc have their own distinct non-overlapping compositional fields in the annite – siderophyllite – phlogopite – eastonitequadrilateral (...

This work aimed to evaluate the chemical composition of essential oils from Catha edulis Forsk collected in Day Forest Republic Djibouti. Additionally, vivo toxicity studies, biochemical profiling, and hematological tests were conducted determine biological activity investigated oils. Finally, vitro performed investigate antibacterial The obtained at yields 0.75%. Chromatographic analysis ident...

Most of the papers in this symposium are concerned with dynamic studies: isotopic tracers may provide information about the metabolism of labelled molecules within the living body which cannot be obtained by any other means. However, in the measurement of body composition, isotope techniques are in general less powerful. If you wish to know how much water, protein, fat or mineral a whole body o...

The present paper presents normal values for the contents of water, sodium, potassium, calcium, magnesium, phosphorus,chloride, copper, and iron in peripheral nerves (tibialis, fibularis prolundus, and ulnaris) in individuals without any neurological condition. This study constitutes a basis for the interpretation of other data, still being gathered, relating these normal values with those obta...

The aim of this study was to investigate the effect of inhibition of Marrubium astranicumleaves extract on the corrosion of carbon steel in hydrochloric acid solution by using weightloss and tafel polarization methods. Inhibition was found to increase with increasingconcentration of the leaves extract. The inhibition efficiency of this extract at an optimumconcentration of 100 mg L-1 was 99.9 %...

objective: in order to use natural compounds in controlling plant pests and diseases, many researchers in recent years have studied the antifungal effects of essential oils and plant extracts.  the purpose of this study was to investigate the chemical composition and antifungal effects of echium khuzestanium and marubbium anisodan extracts. methods: after extraction and preparation of different...

Atmospheric trace gases have an important impact on Earth’s radiative budget, the oxidative or cleansing ability of the atmosphere, the formation, growth and properties of aerosols, air quality, and human health. During recent years, the coupling between atmospheric chemistry and climate has received particular attention. Therefore, research is now focused on the composition and processes in th...

In order to fully understand the mechanisms of human physiology it is important to have an understanding of the chemical composition of the body. This will come in handy when considering the various interactions between cells and structures. We will gloss over the basic chemistry; however, if there are specific questions with regards to chemistry and its effect on biological function feel free ...

THis paper presents the results of a study of the chemical composition of subretinal fluid from cases of retinal detachment, with particular reference to the protein and ascorbic acid content of the fluid. Many workers have studied the chemical composition of subretinal fluid obtained from patients undergoing surgery for retinal detachment. It is generally agreed that the subretinal fluid conta...
