Heterogeneous proton exchange membranes (PEM) are synthesized using the dry phase inversion technique. The casting solutions are prepared by dispersing a finely ground cation exchange resin particle in N,N-dimethylacetamide (DMAc) solution of polyvinyl-chloride (PVC). Results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...

Aluminium salt slag (also known as aluminium salt cake), which is produced by the secondary aluminium industry, is formed during aluminium scrap/dross melting and contains 15-30% aluminium oxide, 30-55% sodium chloride, 15-30% potassium chloride, 5-7% metallic aluminium and impurities (carbides, nitrides, sulphides and phosphides). Depending on the raw mix the amount of salt slag produced per t...

Ikan patin merupakan salah satu komoditas unggulan ikan air tawar yang mudah dibudidayakan dan mempunyai kandungan minyak cukup banyak sehingga potensi untuk diekstrak sebagai sumber asam lemak. Kerusakan sering terjadi adalah ketengikan disebabkan oleh proses oksidasi. Untuk mencegah terjadinya oksidasi perlu ditambahkan antioksidan. Antioksidan digunakan ekstrak kunyit antioksidan alami. Pene...

The present study was undertaken to assess the soil fertility status os soils under sugarcane-ratoon-wheat cropping system. Soil samples were collected from farmers fields at three depths viz., 0-15 cm, 15-30 cm and 30-45 analysed for various properties. Results revealed that sandy clay loam in texture, neutral reaction non saline salt content. Mean values of CEC 15.96, 13.13 10.80 C mol (p+) k...

Aminoglycosides are still widely used for treatment of gram-negative sepsis in critically ill patients. The most reported electrolyte abnormalities related to these drugs are hypokalemia, hypomagnesemia, and hypocalcemia. In this study potential benefit of atorvastatin in prevention of amikacin-induced electrolytes imbalances has been evaluated. In this trial 44 patients were assigned to the at...
