The objective of this work was design, characterization, and optimization of controlled drug delivery system containing antibiotic drug/s. Osmotic drug delivery system was chosen as controlled drug delivery system. The porous osmotic pump tablets were designed using Plackett-Burman and Box-Behnken factorial design to find out the best formulation. For screening of three categories of polymers, ...

Before the First World War, almost all dyes were applied from solution in an aqueous dyebath to substrates such as cotton, wool, silk and other natural fibres. However, the introduction of a man-made fibre, cellulose acetate, with its inherent hydrophobic nature, created a situation where very few of the available dyes had affinity for the new fibre. Water-soluble anionic dyes had little substa...

Blood samples were collected from 20 healthy miniature Caspian horses at 37 °C. Isolation of cryoglobulin was performed based on a standard method in present study. Harvested sera were kept at 4 °C for two hours and then examined for cryoglubolin. Four serum samples containing precipitate Suspicious of containing cryoglobulin were selected. Subsequently serum protein electrophoresis was perform...

Abstract Aims Organic carbon has been reported in deep regolithic profiles to depths of tens metres, but the composition compounds is unknown. Methods Residual form non-volatile low molecular weight (LMWC) was characterised three soil a depth 19 m under farmland south-western Australia following extraction with ethyl acetate and analysis by GC/MS. Pyrolysis off-line thermochemolysis were used c...

Thin films made of a polymer (cellulose triacetate, CTA) and plasticizer have been studied as novel sorptive phases for chlorpyrifos, triclosan tonalide. The preparation is reproducible only requires the to be added into an organic dispersion containing CTA. evaporation solvent leaves easy manipulate continuous homogeneous thin film, which has investigated in terms both composition extraction e...

AbstractOil Palm Empty Fruit Bunch (OPEFB) is a type of solid waste from the palm oil processing industry. The components OPEFB include cellulose, hemicellulose, and lignin. has large cellulose content, so it possesses potential to be used as bioplastic material. purpose this research was examine stages bioplastics' production process its characterization. content raw material during isolation ...
