The plasticity index has often been invoked as an indicator of the most likely condition for scuffing of metals. The particular condition for initiating scuffing was thought to be 2% plastic strain in contacting asperities, which would lead to adhesion between asperities. E~eriments were done to validate the hypothesis using low alloy steels and stainless steel, lubricated with plain mineral oi...

We report the successful application of low-power (approximately 30 mW) laser radiation as an optical heating source for high-speed real-time polymerase chain reaction (PCR) amplification of DNA in nanoliter droplets dispersed in an oil phase. Light provides the heating, temperature measurement, and Taqman real-time readout in nanoliter droplets on a disposable plastic substrate. A selective he...

Essential oil was extracted from peels of sweet orange fruits by supercritical technique and the resulting compounds were analyzed by gas chromatography. After emulsifying with tween-20 in sterile water, the antibacterial efficacy against Vibrio parahaemolyticus, Salmonella typhimurium, Escherichia coli, and Staphylococcus aureus, which were inoculated on the surfaces of samples of stainless st...

Pistachio as a strategic product has a particular position among Iranian productions and is one of the most important non-oil exports after carpet. In this study, after primary processing such as dehulling, washing, drying and roasting, pistachio nuts were packed in four different atmospheres including N2, CO2, vacuum and ambient air. Storage temperatures were 20 C and 40 C for a 12 month perio...

Design of Experiments (DoE) is a powerful guiding tool that can help researchers to identify the main variables that affect the performance characteristics. The present paper elaborates on the optimization and prediction of reaction parameters like type of plastic, catalyst, and temperature using Taguchi’s L9 orthogonal array method with three levels and three parameters to obtai...

The possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of Wood-Plastic novolac has been proved by using Differential Scanning Calorimetry (DSC) and Fourier Transformed Infra Red (FT-IR) spectroscopy. Synthesis of novolac with different concentrations (10, 20 and 30 wt %) of water insoluble fraction were performed. It was found that mechanical p...

Plastic is one of the human needs in everyday life, as a place to wrap food and drinks, because plastic practical, clean, makes it easy for humans. also an artificial inorganic material composed chemicals that are quite harmful environment. To deal with waste, way needed, process waste into materials more useful have benefits nature, by recycling fuel, namely fuel form oil. By processing oil, b...
