water quality aspect with regard to dissolved oxygen was studied for a 24 kilometer stretch of malaprabha river in karnataka state, india. main objective of the research was to simulate the predicted dissolved oxygen depletion due to the waste load allocation in the river with the ambient observed values of dissolved oxygen, and to ascertain the application of mathematical modeling for predicti...
Faecal pollution in stormwater, wastewater and direct run-off can carry zoonotic pathogens to streams, rivers and the ocean, reduce water quality, and affect both recreational and commercial fishing areas of the coastal ocean. Typically, the closure of beaches and commercial fishing areas is governed by the testing for the presence of faecal bacteria, which requires an 18-24 h period for sample...
Temporal and spatial distribution of water components in watersheds, estimation of water quality, and uncertaintiesassociated with these estimations are important issues in freshwater studies. In this study, Soil and Water AssessmentTool (SWAT) model was used to estimate components of freshwater availability: blue water (surface runoff plus deepaquifer recharge), green water flow (actual evapot...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
From the abstraction point and the entrance of water in a Water System (WS) till its discharge back to the environment, water passes through a number of treatments and uses that directly affect its quality. The water quality changes several times while the water returning to the environment at a discharge point into the sea, a lake or a river has poorer quality compared to the water entering th...
background: provision of safe drinking water is one of the basic needs of every society and it will only be possible through preventive and comprehensive management of drinking water security programs such as haccp. hazard analysis critical control point (haccp) is an internationally accepted process control system which includes recognition and determination of risk factor properties of proces...
background: groundwater resources in arid and semi arid regions are very important. groundwater is contaminated by agricultural, industrial and municipal activity which as a result reduces its quality. investigating of the chemical quality of the groundwater is emphasized to identify pollutant environmental impacts associated with incorrect waste disposal practice. this research investigated th...
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...
the fish assemblage and diversity in relation to water quality of three coastal rivers sita, swarna and varahi of udupi district, karnataka, india was studied. 71 species representing 7 orders, 20 families and 41 genera were recorded from 21 sites along the three rivers. species composition varied longitudinally in relation to the environmental factors of the habitat. the downstream change in t...
Environmentally friendly nature and the direct impact of gabion weirs on the quality parameters of rivers as well as simple design and construction of such structures, has putted them under consideration in the recent years. In this research, Hydraulic parameters of gabion crump weirs including water surface profile, discharge coefficient and through flow discharge are investigated numerically ...
