Fresh ripened Guavas were procured from entrepreneur’s field and were weighed, sorted, washed, lye peeled before crushing and sieving to get guava pulp for preparation of different products such as RTS, Nectar and guava bar. Physico-chemical properties (Total Soluble Solids (TSS) Acidity, Ascorbic acid Content (AAC), Thermal properties, Particle Size analysis) and microbial properties (bacteria...

The Rayon grade pulp (RGP) drain effluent of pulp and paper mill was studied to find out pollutant loading and its control measures by low cost and efficient treatment method. Upflow anaerobic fixed packed bed reactor (UAFPBR) with brick ballasts as packing material was used for this purpose. This was compared with conventional anaerobic treatment method. The digested slurry was taken as inocul...

In general, skateboard wheels are made from a mixture of polyurethane (PU) so that they elastic, lightweight, and strong. However, this material is classified as toxic material, difficult to obtain, the price relatively expensive. Therefore, alternative raw materials more environmentally friendly, non-toxic, easy find, have sufficient availability needed. Banana trees most abundant easily found...

Bone cement material is one of the key materials in bone surgery and orthopedic medicine. In this study, commercial polymethyl-methacrylate was mixed with boric acid zinc borate to reduce reaction temperature cement. The observation changes during polymerization using laser thermometer thermal camera showed that use boron compounds decreased at least 10 °C which very critical for biomaterial us...
