Current refigeration technology has an important influence in improving the quality of food products. The purpose this study is to find out how much difference performance generated from expansion device form two capillary pipes different diameters and know power consumption electricity used, so that it knows electric per day. method used test ice cream maker refrigeration system, by tes...

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

Fermented maize product ‘ogi’ is a popular weaning and breakfast cereal in sub-Saharan Africa traditionally made from maize, sorghum or millet. It is prepared by steeping clean grains in water at room temperature (25±2 0C) for two to three days [1]. The steep water is decanted and the fermented grain is washed with clean water and then wet-milled. The bran is removed by wet sieving and the slur...

In a new experiment at the Final Focus Test Beam at SLAC a low-emittance 46.6-GeV electron beam is brought into collision with terawatt pulses of 1054 nm or 527 nm wavelength from a Nd:glass laser. Peak laser intensities of 10 W/cm have been achieved corresponding to a value of 0.6 for the parameter = eE=m!0c. In this case an electron that crosses the center of the laser pulse has near-unit int...

This paper presents the development of low cost Nano membrane fabrication system. The system is specially designed for anodic aluminum oxide membrane. This system is capable to perform the processes such as anodization and electro-polishing. The designed machine was successfully tested for ‘mild anodization’ (MA) for 48 hours and ‘hard anodization’ (HA) for 3 hours at constant 0C. The system is...

Vacuum dried Metronidazole hydrochloride (MTZ) loaded Crosslinked polymeric blend of Poly(vinyl)alcohol (PVA) and Gelatin(GE) in different ratios by 30 freeze/thaw cycles (FTC) tested for stimuli sensitivity and crosslinking at various pH, temperature, ionic concentration and oscillatory test along with dye absorption test showed maximum swelling in alkaline pH and decreased swelling with incre...

Logam berat adalah kelompok logam yang memiliki densitas lebih besar dari 5 g/cm3 pada umumnya mempunyai sifat toksik dan berbahaya bagi organisme hidup. Salah satu cara untuk menyerap dengan adsorpsi menggunakan karbon aktif sekam padi. Penelitian ini bertujuan menguji efektifitas padi terhadap penyerapan Pb serta mengkaji kondisi optimum menghasilkan efisiensi masing-masing variabel proses RS...
