Acute respiratory infection (ARI) is a that causes disruption of normal activities. Amoxicillin the antibiotic first choice generally given to patients with ARI. Compliance in use antibiotics for less than five days will determine success therapy so frequency drug also affects patient compliance taking medication. Granule mucoadhesive amoxicillin trihydrate formula designed addition chitosan po...

Cell suspensions of Olea europaea var. Galega Vulgar grown in batch culture with 0.5% (w/v) glucose were able to transport D-[(14)C]glucose according to Michaelis-Menten kinetics associated with a first-order kinetics. The monosaccharide carrier exhibited high affinity (K(m) approximately 50 micro M) and was able to transport D-glucose, D-fructose, D-galactose, D-xylose, 2-deoxy-D-glucose and 3...

Kinetics and selected variables (temperature, particle size and time) for extraction of Terminalia Catappa L Kernel Oil (TCKO) were investigated using solvent extraction. Kinetic models studied were: parabolic diffusion, power law, hyperbolic, Elovich and pseudo-second-order. In ascending order, the best-fitted models at the optimum temperature and oil yield were Elovich’s model, hyperbolic...

It is possible to alter the permeability of ethyl cellulose membrane with certain materials such as surfactants. In this study the effect of surfactant concentration and different HLB values on the release rate of atenolol from ethyl cellulose-coated tablets was evaluated. The results showed that when the concentration of surfactant increased, the rate of drug release also increased. The kineti...

A topical o/w cream containing tretinoin microspheres was prepared. Gelatin microspheres of tretinoin were prepared using coacervation method. These microspheres contained about 50% w/w tretinoin. The particle size range of microspheres was between 90-150 m m. In vitro drug release from microspheres and a cream formulation was studied. It was shown that drug release from microspheres followed H...

Adsorption Kinetics describes the rate at which solute is adsorbed and resident time of adsorbates on solid-liquid interface. isotherms play important role in determining interaction between adsorbate adsorbent optimum adsorption capacity adsorbent. This article considered selected kinetics models. Pseudo first order, second Elovich, Bhattacharya Venkobachar, Natarajan Khalaf were reviewed assu...

Kinetics of oxidation of L-valine (Val) by manganese(III) pyrophosphate has been studied as a function of pH (0.94-1.90) at 313 K. The reaction shows a first-order dependence of rate each on [Mn(III)] and [Val], a fractional-order on [H], and an inverse fractional-order each on [Na4P2O7] and [Mn(II)]. Effects on the rate of anions, such as [F], [Cl] and [ClO4], and the dielectric constant of th...

The model reduction methodology of computational singular perturbation (CSP) is enhanced for chemical kinetics problems. The leading order converged CSP-refined fast basis vectors are obtained analytically by exploiting the special format of the given reaction-specific chemical kinetics data. The leading order net reaction rates of the fast reactions (after they are exhausted) are also obtained...
