The determination of neurotransmitters and adrenoreceptor drugs is highly essential due to their specific functions in the human body. In this work, the determination of carvedilol (CAR) and dopamine (DA)...
A study was carried out in coastal Ramanathapuram district to find out the influence of sea water intrusion on quality of irrigation water. The analytical results indicated that the ground water in the study area was sodic. The Residual Sodium Corbonate (RSC) value was negative in ninety three percent of the samples analysed. The Sodium Adsorption Ratio (SAR) of irrigation water was found to be positively associated with SAR of the Soil Water Extract (SWE). A wide variations in the other quality parameters viz. potential salinity, permeability index, sodium ratio and adjusted SAR were observed due to the intrusion of sea water in to the ground fresh water aquifers of the coastal belt at various degrees. Significant positive correlation was noticed between SAR of irrigation water and the SWE of irrigated surface soils (r=0.231) No relationship existed between SAR and ESP of the coarse taxtured soils in the coastal areas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
