Water stuck in the ear is a common problem during showering, swimming or other water activities. Having trapped canal for long time can lead to infections and possibly result hearing loss. A strategy emptying from shake head, where high acceleration helps remove water. In this present study, we rationalize underlying mechanism of ejection/removal by performing experiments developing stability t...
Chronic erosive dermatopathy (CED) is a disease of intensively farmed Murray cod in Australia that has been reported in association with the use of groundwater (mechanically extracted from shallow boreholes) supplies. CED results in focal ulceration of the skin overlying sensory canals of the head and flanks. Trials were conducted at an affected fish farm to study the development of the conditi...
Discharge of raw domestic wastes containing human enteric viruses into water courses, consumption of untreated water from canals, streams, and shallow wells in villages, and cross-contamination of water in the distribution system because of intermittent water supply in urban areas continue to cause widespread outbreaks of infectious hepatitis in India. To detect a low number of viruses in 50- t...
the construct of self-efficacy has received increasing attention in research over the past two decades. many studies have been carried out 1.3 significance of the study this study has pedagogical implications since improving students’ self- efficacy and autonomy is important for promoting actual performance on classroom academic tasks. in academic settings, it has been shown that self-effi...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...

Irrigation canals are large-scale systems, consisting of many interacting components, and spanning vast geographical areas. For safe and efficient operation of these canals, maintaining the levels of the water flows close to prespecified reference values is crucial, both under normal operating conditions as well as in extreme situations. Irrigation canals are equipped with local controllers, to...
