This study aimed at monitoring the changes of fluorescent components in wastewater samples from 22 Korean biological wastewater treatment plants and exploring their prediction capabilities for total organic carbon (TOC), dissolved organic carbon (DOC), biochemical oxygen demand (BOD), chemical oxygen demand (COD), and the biodegradability of the wastewater using an optical sensing technique bas...

We tested the validity and reliability of the BioSpace InBody 320, Omron and Bod-eComm body composition devices in men and women (n 254; 21-80 years) and boys and girls (n 117; 10-17 years). We analysed percentage body fat (%BF) and compared the results with dual-energy X-ray absorptiometry (DEXA) in adults and compared the results of the InBody with underwater weighing (UW) in children. All bo...

Optimization of operational parameters wastewater treatment system using the modeling technique may lead to enhance system’s and efficiency. The present research was carried out investigate efficiency conventional trickling filter (CTF) cascade cum (CCTF) for domestic wastewater. Both systems (CTF CCTF) were operated a period four months under temperature range 21–48 °C. maize cob (MC) date pal...

Partially treated black water from septic tanks and grey water from households in Kuching City were polluting the Sarawak River. A pilot scale ecological sanitation was implemented where blackwater was held in septic tanks and greywater was channeled to a grease trap, biofilters and a constructed wetland before discharge. The objectives of this study were to evaluate the efficiency of the biofi...

We are concerned with the inverse problem of detecting sources in a coupled diffusion-reaction system. This problem arises from the Biochemical Oxygen Demand-Dissolved Oxygen model() governing the interaction between organic pollutants and the oxygen available in stream waters. The sources we consider are point-wise and simulate stationary or moving pollution sources. The ultimate objective is ...

wastewater of hospitals can cause many risks to public health due to having a variety of pathogenic microorganisms, pharmaceutical substances, and other hazardous toxic substances. the aim of this study was to evaluate the chemical quality of effluents from wastewater treatment plant of falsafi hospital and hakim jorjani hospital in gorgan, iran, and to compare them technically and economically...

in iraq, waste generation was increased after 2003 war events due to intensepopulation developmentand economic growth. the limitation of designable system for municipal solidwaste (msw) management led toserious problems regarding environment and human health. sanitary landfill in the south of kirkuk is the first kindof effective system for municipal solid waste management in iraq. in the first ...

This study aims to examine the impact of gender diversity in Board Directors (BOD) on firm performance—return assets (ROA) and return equity (ROE)—using a sample Palestinian non-financial companies for period 2008–2015. Gender was measured as percentage women BOD, dummy variable existence at least one woman BOD. The employed method two-stage squares (2SLS) address endogeneity issues relationshi...
