stabilities and quantum molecular descriptors of cyclophoshphamide (an anticancer drug)-functionalized (8,0) zigzag and (4,4) armchair carbon nanotubes (cnts) complexes in water were studied using density functional theory (dft) calculations. two attachments namely the sidewall- and tip-attachments are considered for the model constructions. calculations of the total electronic energy (et) and ...

Seasonal variation on physico-chemical quality of well water at Eloor industrial area, Kerala was studied. A total of 100 samples, 25 each during four different seasons, viz. summer, premonsoon, monsoon and post monsoon were collected during the year 2009 and analyzed for temperature, pH, total hardness, Chemical Oxygen Demand, concentration of nitrate, fluoride, iron, heavy metals like lead, m...

In a recent issue of Environmental Health Perspectives, James et al. reported that lifetime exposure to low levels of inorganic arsenic in drinking water was associated with increased risk of coronary heart disease (CHD). The study was well performed and reported, except for the omission of two possible confounders related to an individual’s drinking water—magnesium content and total hardness. ...

The study carried out through collected data of Ministry of Drinking Water & Sanitation on on-line source. Block level village wise water quality analysis which has given in the ministry website is downloaded and utilized to view the water quality state in the area. Location map of the study area and contaminant map of iron, hardness and TDS also has been generated by using GIS software for the...

Portadown and Lurgan have had very similar populations during the years 19501970 and the water supply to each has been established for the past 50 years. Portadown draws its very soft water by aqueduct from two reservoirs on the western face of the Mourne Mountains (at Foffany and Spelga), and Lurgan is supplied by less soft water drawn from Lough Neagh which is at that area largely supplied by...

The mean annual prevalence at birth of congenital malformations of the central nervous system for the three years 1964-6 in 48 local authority areas in South Wales was negatively correlated (r = -0.402, P<0.01) with estimates of the mean total hardness of the related water supplies.The mean annual perinatal mortality rate from anencephalus for the five years 1963-7 in 58 county boroughs in Engl...

The test panels obtained from Scots pine (Pinus sylvestris L.) and Eastern beech (Fagus orientalis L.) were initially adjusted to have 8%, 10%, and 12% moisture content in this study. One-component semimatte and two-component water borne varnishes were applied on the surfaces in order to investigate the effect of the type and the moisture content of the wood on the hardness and the gloss values...

Turbine is the most important part of hydro power plant which converts the potential energy of water into mechanical energy. The presence of silt in water erodes the turbine material. Erosion of turbine decreases the performance of turbine, life of the turbine as well as loss of power generation. This paper presents a new approach for the study of silt erosion of hydro turbine. In this study, w...

The surface water chemistry of Thiruvananthapuram Museum Lake was carried out in the period of February 2013 to January 2014. Correlation study of the parameters and overall CCME WQI (Canadian Council of Ministers of the Environment Water quality Index) was also prepared in the study for the lake water. The parameters analysed are cations such as Ca2+, Na+, Mg2+ and K+ and the anions like PO4-,...
