Qualitative and quantitative studies on changes of coastal geomorphology and shoreline of Karnataka, India have been carried out using toposheets of Survey of India and satellite imageries (IRS-P6 and...
This work concerns the development of quantitative estimation techniques using the K edge-jump ratio of X-ray absorption spectrum recorded through total-electron-yield measurements. The three methods ...
Palygorskite accounts for a major portion of the minerals present in paleosols in the central Iranian plateau. The identification and quantitative determination of this clay mineral is of great import...
Estimation of DDT by GLC (gas liquid chromatography) in the PCSIR strain of Musca domestica L. Shows that 59.69 ng/fly DDT was found in the sample extracted with hexane and 55.74 ng/fly in the sample ...
The addition of a 10% talc internal standard to North Pacific sediments allows the relative abundances of clay minerals to be determined both accurately and precisely by X-ray powder diffractometry. L...
An infrared method has been developed for estimating kaolinite in sediments. Hydroxyl stretching bands of kaolinite in sediments can be recorded by using a differential technique which eliminates the ...
Sesquioxidic soil clays from Oxisols in South Africa, Australia and Brazil, and two clays from Andosols in Japan and New Zealand, were investigated by selective dissolution techniques. Acid ammonium o...
