Abstract Acetylation is a method of chemically modified starch that can be used to improve the physicochemical properties starch. The aim study was obtain pH and concentration acetic anhydride which gave best effect on characteristics acetylated sago arranged using completely randomized design with factorial pattern in combination suspension 7.0; 8.0; 9.0 10.0 concentrations 3%, 6%, 9%, 12% 15%...

i ntroduction: our study was designed to assess the effect of the submucosal injection of dexamethasone on postoperative discomfort after surgical removal of impacted mandibular third molars. m at erials and methods : twenty six patients with bilaterally bony impacted mandibular third molars were recruited to this split mouth study. on the study side, prior to surgery, 8 mg of dexamethasone was...

The effect of some amphipilic diblock-copolymers and comb-polymers on a balanced Winsor III microemulsion system is investigated with the quaternary system n-octyl-β-d-glucoside/1-octanol/n-octane/D2O as basis system. The diblock-copolymers are polyethyleneoxide-co-polydodecenoxide (PEO x PEDODO y ) and polyethyleneoxide-co-polybutyleneoxide (PEO x PEBU y ), constituted of a straight chain hydr...

The alteration of cellular calcium sequestration has been postulated to be a primary mechanism in the initiation of irreversible cell damage. Crude oil has been shown to cause concentration- dependent inhibition of calcium influx and mitochondrial swelling which may relate to its toxicity. Nigerian 'Bonny' Light Crude Oil (BLCO) is produced in the Niger-Delta region of Nigeria where oil spills ...

Hydro-distilled essential oil (EO) from the leaves of the western Mediterranean and Moroccan endemic plant Tetraclinis articulata was analyzed by GC/MS and examined for its acute toxicity on mice, in order to establish the safe doses. Furthermore, the anti-Inflammatory activity was evaluated based on carrageenan and trauma induced rats paw edema and the antioxidant potential has been investigat...

In this paper, a simplified formulation for compositional reservoir simulator is presented. These types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. The procedure for solving compositional model equations is completely described. For equilibrium calculation, property estimation Peng Robinson equation of state is used. This equation ...
