The physicochemical qualities of a typical rural-based river were assessed over a 12-month period from August 2010 to July 2011 spanning the spring, summer, autumn and winter seasons. Water samples were collected from six sampling sites along Tyume River and analysed for total nitrogen, orthophosphate, biochemical oxygen demand (BOD), temperature, pH, dissolved oxygen (DO), electrical conductiv...

Concentrations and temporal changes in concentrations of nitrate and total dissolved solids (TDS) in groundwater of the Bunker Hill, Lytle, Rialto, and Colton groundwater subbasins of the Upper Santa Ana Valley Groundwater Basin were evaluated to identify trends and factors that may be affecting trends. One hundred, thirty-one public-supply wells were selected for analysis based on the availabi...

The efficiency of part lactation test day (TD) records in first parity for the genetic evaluation of bulls and cows using a random regression model (RRM) and a fixed regression model (FRM) was studied, modelling the random and fixed lactation curves by Legendre polynomials. The data set consisted of 9 242 783 TD records for first lactation milk yield of 1 134 042 Holstein Friesian heifers. The ...

PURPOSE Tumor deposits (TDs) are defined as satellite peritumoral nodules in the peritumoral adipose tissue of a primary carcinoma without histologic evidence of residual lymph node in the nodule. We aimed to investigate the relation between TDs and clinicopathological characteristics of gastric cancer and to evaluate the effect of TDs on prognosis. METHODS One hundred and seven non-metastati...

Individuals with two red hair colour (RHC)-MC1R genetic variants have light skin and blond/reddish hair and, in comparison with those without such alleles, are at an increased risk of developing melanoma. Our study investigated the association of RHC variants and the Total Dermo-scopy Score (TDS), and the items that make up the TDS, in those with atypical naevi and melanomas from high risk mela...

Wetlands are land areas that are wet during part or all of the year. Constructed wetlands are man-made systems that mimic the functions of natural wetlands applied for wastewater treatment. The aim of this research is to investigate the feasibility of using a constructed wetland for treatment of kitchen waste water from hostel mess. The wetland plant species grown in the constructed wetland is ...

The water quality and phytoplankton of Ufiobodo Ebonyi River reservoirs were studied for nine months from March to November, 2019 evaluate the suitability domestic supply habitat aquatic organisms. Temperature, pH, conductivity, total dissolved solid (TDS), transparency, oxygen (DO) depth measured in situ, while samples collected determination nitrate, iron, silicate phosphate laboratory. Phyto...

Telah dilakukan penelitian tentang pengaruh wadah penyimpanan air terhadap nilai DO dan TDS pada aliran sungai Metro di Kota Malang. Tujuan dari ini adalah untuk mengetahui perubahan kadar tercemar setelah dalam waktu 24 jam tertentu. Sampel yang diambil berasal berlokasi Malang terindikasi cemaran limbah pasar. Air empat titik yaitu titik1 berjarak 250 meter sebelum pintu pembuangan pasar, 2 m...

Precipitation/dissolution reactions coupled with solute transport are modelled as a cellular automaton in which solute molecules perform a random walk on a regular lattice and react according to a local probabilistic rule. Stationary solid particles dissolve with a certain probability and, provided solid is already present or the solution is saturated, solute particles have a probability to pre...

landfill leachates are potential threats for environmental degradation. this study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in kolkata, india using leachate pollution index. the results of the physico-chemical ...
