Temporal-scale spectral variability analysis of water quality parameters to realize seasonal behaviour of a tropical river system - River cauvery, India.

This paper describes the Time series analysis of river water quality with emphasis on variation in parameters as evidenced by statistical approach and mathematical models. The extensive study enabled to differentiate and realize the behaviour of river and catchment’s changes induced by human activities. The Time series analysis evaluation indicated trivial variation and movement in the water quality as reflected by the changes in the catchment characteristics. Although the observed trends showed an insignificant human contribution to basin hydrology and river water chemistry, noticeable human activities and unsustainable practices steadily contributed to change in water quality from the existing long term spectral signatures to short term spectral signatures. It is inferred that short term spectral signature exhibited on temporal scale by a monitoring program of this kind reflects an insalubrious river system and long term gradual changes in spectrum is an indication of healthy system. Monitoring and analyses of these decisive changes in water quality parameters over a period could be a powerful tool for assessing general river water quality and management plan.

Short rib polydactyly syndrome - type 2 (Majewski).

Short rib polydactyly syndromes (SRPS) are a group of inherited autosomal recessive skeletal dysplasias. It is characterized by the triad of micromelia, polydactyly and short horizontal ribs with or without visceral involvement. We report a case of SRPS-2 in a fresh stillborn and discuss the differential diagnosis.

Groundwater quality--assessment on Anekal Taluk, Bangalore Urban district, India.

Water as a resource, basic amenity and universal solvent is shared by population. The physicochemical and biological quality study of Anekal Taluk has been taken up to evaluate its suitability for potable purposes. 1026 water samples were collected from bore well, hand pumps of 272 villages covering in Anekal Taluk. The quality of groundwater has been made through the analysis of pH, colour, electrical conductivity, turbidity, total dissolved solids, alkalinity, chlorides, total hardness, calcium, fluoride, nitrate, sulphate, iron and E. coli. The quality of groundwater assessed in the study area is discussed in detail.
