Background & Aims of the Study: In recent years, groundwater resources of Seyed Gholi in Saveh area has been deteriorated because of some factors such as unconventional withdrawal in order to agricultural and industrial uses. This study has been conducted to evaluation of chemical quality and salinity origin of groundwater in this region. Materials & Methods: In order to survey on salinity ...
Temperature Discovery Search (TDS) is a new minimaxbased game tree search method designed to compute or approximate the temperature of a combinatorial game. TDS is based on the concept of an enriched environment, where a combinatorial game G is embedded in an environment consisting of a large set of simple games of decreasing temperature. Optimal play starts in the environment, but eventually m...
Total dissolved solids (TDS) concentration determination in water bodies is sophisticated, time-consuming, and involves expensive field sampling laboratory processes. TDS has, however, been linked to electrical conductivity (EC) temperature. Compared monitoring concentrations, EC temperature simpler, inexpensive, takes less time. This study, therefore, applied several machine learning (ML) appr...
This study compares the performance of simulated shallow ponds vegetated with Lemna minor L. under controlled and semi-natural conditions for the treatment of simulated wastewater containing textile dyes. The objectives were to assess the water quality outflow parameters, the potential of L. minor concerning the removal of chemical oxygen demand (COD) and four azo dyes (Acid blue 113, reactive ...
روش های ژئوالکتریکی در منطقه دوغ، واقع در استان گلستان، به منظور تعیین گسترش جانبی و عمقی سازندهای حاوی آب اجرا شده است. پارامترهای هیدرولوژیکی مانند tds و ec نیز از سه چاه آب موجود در منطقه مطالعاتی به دست آمده اند. هدف از این بررسی های ژئوالکتریکی، تشخیص آبخوان های حاوی آب های زیرزمینی و نیز به دست آوردن رابطه ای بین پارامترهای ژئوالکتریکی و هیدرولوژیکی در منطقه مطالعاتی می باشد. به این منظور...
The present study has been conducted to determine the surface water quality of urban area in Savar, Dhaka, Bangladesh by determining some water quality parameters (Transparency, Temperature, pH, EC, Eh, DO, TSS, TDS, TS, BOD5, COD, TOC, Cl-, Br-, SO4-2, NO3-, NO2-, PO4-3, TP, HCO3- and Total alkalinity) as well as the status of phytoplankton’s community in the water from two lakes (Tiger Lake a...

Strong opioids are recommended for treating severe cancer pain in the advanced stages of the disease. Few data are available concerning the efficacy of buprenorphine in cancer pain. We compared transdermal buprenorphine 70 microg/h (BUP TDS) to placebo in an enriched design study. Opioid-tolerant patients with cancer pain requiring strong opioids in the dose range of 90-150 mg/d oral morphine e...
Abstract The study’s goal is to analyze the suitability of sub-surface water Una district for drinking and agriculture purposes. data related physico-chemical parameters groundwater was obtained from Central Groundwater Board’s website compared BIS standard (10500:2012). values Ca 2+ , Cl − F SO 4 2- were found be below acceptable limit. pH, TDS, Alkalinity, Mg TH, NO 3 had that above limit at ...
This study is used the water quality index (WQI), which generated by combining several parameters. gives a helpful representation of overall for public and all intended applications, it demonstrates that pollution beneficial in management decision-making. The Euphrates River was assessed order to determine drinking water. using WQI, includes ten physicochemical criteria. achieved submitting com...
