enhanced coagulation (ec) is defined as the addition of excess coagulation to improve the removal of disinfection by-product (dbps) precursors through the use of conventional water treatment processes. in this research, most of coagulants of ferric chloride (fecl3), poly aluminum chloride(pacl) in removal of most parameters of total organic carbon (toc), dissolved organic carbon (doc), organic ...

Abstract Lakes process both terrestrial and aquatic organic matter, the relative contribution from each source is often measured via ecosystem metabolism resource use in food web (i.e., consumer allochthony). Yet, allochthony are rarely considered together, despite possible interactions potential for them to respond same lake characteristics. In this study, we compiled global datasets of gross ...

BACKGROUND Mosquitoes lay eggs in a wide range of habitats with different physicochemical parameters. Ecological data, including physicochemical factors of oviposition sites, play an important role in integrated vector management. Those data help the managers to make the best decision in controlling the aquatic stages of vectors especially using source reduction. METHODS To study some physico...

A phase I study of S-1 and biweekly docetaxel (DOC) combination therapy was conducted to determine the maximum tolerated dose (MTD) and pharmacokinetic parameters. Fourteen patients with advanced or recurrent gastric cancer were analyzed. The treatment consisted of S-1 [body surface area (BSA) <1.25 m2:80 mg/day, 1.25≤ BSA <1.50 m2: 100 mg/day, 1.50 m2≤ BSA; 120 mg/day, orally, day 1-14) and DO...

We present a new atom type classification system for use in atom-based calculation of partition coefficient (log P) and molar refractivity (MR) designed in part to address published concerns of previous atomic methods. The 68 atomic contributions to log P have been determined by fitting an extensive training set of 9920 molecules, with r2 ) 0.918 and σ ) 0.677. A separate set of 3412 molecules ...

A novel sponge submerged membrane bioreactor (SSMBR) was developed to effectively remove organics and nutrients from wastewater. Sponge is introduced within the SSMBR as a medium for the attached growth of biomass. This paper evaluates the effects of new and acclimatized sponges for dissolved organic carbon (DOC) removal from wastewater at different mixed liquor suspended solids’ (MLSS) concent...

the aim of the present study was to investigate the relationship between the polar surface area and other molecular properties of the model drugs and their transdermal permeability across the rat skin. few model drugs which are weakly acidic (ibuprofen, aceclofenac and glipizide) and weakly basic (olanzapine, telmisartan and sildenafil citrate) were selected for the study based on polar surface...

The study evaluated the shelf life of buffalo meat in refrigerated storage. The shelf life was evaluated for 9 days where all the physicochemical parameters were analysed on alternate days i.e. on the 0th, 3rd, 5th, 7th and 9th days. Buffalo meat was kept in polystyrene foam trays which were covered with PVC film and stored at refrigeration temperature. A significant change was recorded in phys...
