the potential of six economically cheap agricultural waste materials, viz. rice husk, betel nutpeels, sugarcane molasses, tea waste, mustard oil cake and saw dust, was investigated for copper and leadremoval from aqueous solutions under batch and continuous conditions. the effect of ph, contact time,sorbent dose and initial metal ion concentration on the uptake of copper and lead was first exam...

OBJECTIVES To develop prognostic models for risk of a breakthrough seizure, risk of seizure recurrence after a breakthrough seizure, and likelihood of achieving 12-month remission following a breakthrough seizure. A breakthrough seizure is one that occurs following at least 12 months remission whilst on treatment. METHODS We analysed data from the SANAD study. This long-term randomised trial ...

solute transport processes are affected by soil pore water velocity distribution. pore size distribution, which can be used to infer pore water velocity distribution, can be estimated from a soil water retention curve (n). in this study, a solute breakthrough curve was simulated using soil hydraulic parameters in four different soils. to evaluate the proposed model, predictions were compared to...

ground water is the major source of drinking water in rural and semi-urban areas of assam. it contains an excessive amount of iron (1 to 10 mg/l). people living in rural and semi-urban areas of assam uses indigenous household iron filter units – developed using community prepared wooden charcoal (cpwc) and river sand (rs) as filter media. cpwc and rs processed and respectively termed as process...

Background Following cerebral arteriovenous malformation (AVM) surgery, severe brain edema and hemorrhage may be caused by postoperative normal perfusion pressure breakthrough (NPPB). Sedation is necessary for this population. It is a challenge for the anesthesiologist to maintain hemodynamic stability without interfering with the neurological assessment. In Japan, propofol is contraindicated f...
