Background & Aims of the Study: Corrosion and scaling play undesirable effects on transmission and distribution system of drinking water. The aim of this study was to assess the corrosion and scaling potential of drinking water resources in Babol city, Iran. Materials and Methods: Totally, 54 water samples were collected from 27 wells in spring and autumn. Calcium har...

The challenging problems faced by the tannery based countries are the safe disposal of the sludge generated by the effluent treatment plants. In this work, the disposal of the sludge at various generation points such as beam house (BHS) and after tertiary treatment process (TS) is studied. The FT-IR of the beam house sludge confirmed the presence of organic matter at 2880.31cm -1 and calcined p...

Two-message witness indistinguishable protocols were first constructed by Dwork and Naor (FOCS 2000). They have since proven extremely useful in the design of several cryptographic primitives. However, so far no two-message arguments for NP provided statistical privacy against malicious verifiers. In this paper, we construct the first: ◦ Two-message statistical witness indistinguishable (SWI) a...

We consider labeled Traveling Salesman Problems, defined upon a complete graph of n vertices with colored edges. The objective is to find a tour of maximum (or minimum) number of colors. We derive results regarding hardness of approximation and analyze approximation algorithms, for both versions of the problem. For the maximization version we give a 1 2 -approximation algorithm based on local i...

The scenario of the present era shows that the environmental impact was high on water resources. Water is the eternal source for living with nature. The contamination of groundwater resources is hike at many areas. In this paper an attempt has been taken to analyze the physical and chemical parameters groundwater in the city of Tiruppur. The city of Tiruppur is famous for textiles. There is an ...

background: coronary heart disease is one of the most important problems of public health. one risk factor is dyslipidemia. evidence from molecular and animal research and epidemiologic investigations indicate that calcium intake may influence lipid metabolism.but intervention studies have produced conflicting results.objective of this study was to determine the effects of calcium supplementati...

The aim of this study was to evaluate the effects three fresh-water samples with different hardness values (25, 250, and 750 mg L-1 CaCO3) a control (sea water salinity 15% 2500 ± 130.9 on Mugil liza (mullet) juveniles by conducting long-term test (for 50 days). Zootechnical performance [weight gain (WG), feed conversion rate, specific growth survival (%)], stress indicator parameters (glucose)...

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...

A study of water quality parameters of ground water of North, Central and South regions of Kalol Taluka in Gandhinagar district of Gujarat state, India have been carried out during May2006. The observed values of various physico-chemical parameters of water samples were compared with standard recommended by World Health Organization (WHO). The analysis of variance (ANOVA) and t-test have been a...
