FT-Raman spectroscopy is the most useful tool for the purpose of bio-medical diagnostics. In the present study, FT-Raman spectral method is used to investigate the chemical composition of urinary calculi. Urinary calculi multi-components such as calcium oxalate, hydroxyl apatite, struvite and uric acid are studied. FT-Raman spectrum has been recorded in the(More)
In the present study, FT-IR, XRD, TGA-DTA spectral methods have been used to investigate the chemical compositions of urinary calculi. Multi-components of urinary calculi such as calcium oxalate, hydroxyl apatite, struvite and uric acid have been studied. The chemical compounds are identified by FT-IR spectroscopic technique. The mineral identification was(More)
In the present study the human urinary stones were observed in their different chemical compositions of calcium oxalate monohydrate, calcium oxalate dihydrate, calcium phosphate, struvite (magnesium ammonium phosphate), uric acid, cystine, oxammite (ammonium oxalate monohydrate), natroxalate (sodium oxalate), glushinkite (magnesium oxalate dihydrate) and(More)
Land con®guration in combination with nutrient management has the potential to improve the productivity of Al®sols and Vertisols in the semi-arid tropics. A four year (1989±1990 and 1992±1993) ®eld experiment was conducted at Coimbatore, India on Al®sols (Chromic Cambisol) to compare the effect of land con®guration and nutrient management practices on yield(More)
Fourier transform infrared spectroscopy (FT-IR) has been carried out to analyze the chemical composition of soil samples. The soil samples were collected from an industrial environment at Karaikal, Union Territory of Pondicherry, South India. The FT-IR results indicate that soils have different composition, i.e., namely kaolinite, quartz, montmorillonite,(More)
Fourier transform infrared spectroscopy (FT-IR) has been carried out to analyze the organic and inorganic constituent of human urinary stones. Patient's hailing from Rajah Muthiah Medical College and Hospital, Annamalai University, Tamil Nadu, India was selected for the study. The FT-IR results indicate that stones have different composition, i.e., namely(More)
