The present study has been conducted to assess the surface water quality of Halda River from September 2015 to March 2016. DO, BOD5, COD, pH, EC, Chloride, Alkalinity, and Hardness concentrations in water samples have been found to range within 0.93-5.15 mg/L, 30-545 mg/L, 43-983 mg/L, 6.3-7.3, 110-524 uS/cm, 12-56 mg/L, 35-67 mg/L, and 38-121 mg/L, respectively. Multivariate statistical analys...

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-,...

Dye-house water quality is the most important parameter to be confirmed before dyeing; precisely the presence of metal content i.e. Hardness. This research will investigate & analyses the impact of separate hardness (i.e. Calcium, Magnesium & Iron) on particular „Turquoise‟ (C.I. Reactive Blue 21) & a „High Exhaustion‟ class (C.I. HE Red 120, C.I. HE Yellow 84) of Reactive dye on cotton knitted...

The purpose of this study was to evaluate the effect of sports and energy drinks on the surface hardness of different restorative materials over a 6-month period. Forty-two disk-shaped specimens were prepared for each of the four restorative materials tested: Compoglass F, Filtek Z250, Filtek Supreme, and Premise. Specimens were immersed for 2 min daily, up to 6 months, in six storage solutions...

background: the chemical quality of water used for dialysis fluid is a vital factor in the overall care received by dialysis patients. therefore, water used for this purpose should be treated with advanced methods before use for dialysis. the objective of this study was to assess the efficiency of reverse osmosis systems to improve water quality used for dialysis fluid. methods: in this descrip...

AIM OF THE STUDY The aim of this study was to evaluate the effect of at-home (Opalesence/Dr. kit 15%, Ultradent, Products, Inc. South Jordan, UT, USA) and in-office (Superoxol 35%, Sultan Chemists, Inc., Englewood, NJ, USA) bleaching on the surface hardness of the following tooth colored restorative materials: composite resin, Point-4 (P4), Kerr Corporation, Orange, CA, USA; ormocer, Admira (AD...

AIM The aim of this in vitro study was to evaluate the surface roughness and hardness of both unbleached and bleached (opalescence; 10% carbamide peroxide) human enamel brushed with water (without dentifrice), fluoride abrasive dentifrice (Colgate Total) and whitening dentifrice (Natural White). MATERIALS AND METHODS Human enamel samples were obtained from third molars and randomly divided in...

Deep-sea water (DSW), which is rich in micronutrients and minerals and with antioxidant and anti-inflammatory qualities, may be developed as marine drugs to provide intestinal protection against duodenal ulcers. We determined several characteristics in the modified DSW. We explored duodenal pressure, oxygenation, microvascular blood flow, and changes in pH and oxidative redox potential (ORP) va...
