The aim of this study is to evaluate the effects of thermal processing of virgin olive oil, canola and frying oil on chemical oxidative indices (peroxide, p-anisidin value and oxidative stability), acid value and fatty acid compositions. The oil samples were exposed to heat treatment at 180 °C and qualitative parameters were determined at 0, 60, and 90 min after thermal processing. The...

Two onions (Sulfur-1 and Sulfur-4) cultivated with different sulfur applications were thermally processed to elucidate the effects of heat treatment on browning index and antioxidant activity. Sulfur-4 onion had higher sulfur content compared with the Sulfur-1 onion. After thermal processing, browning intensity was different between the two onions juices, with lower values observed for Sulfur-4...

Lavandula angustifolia Mill. (Lamiaceae family) is commonly exploited in different sectors, such as cosmetics, perfumery, and medicine because of its phytochemicals. More recently it has gained attention an edible flower the food beverage industry. Post-harvest technologies can help producers to increase functional beverages market, where there a growing demand for new products rich bioactive m...

BACKGROUND Bioheat models have been proposed to predict heat distribution in multilayered biological tissues after therapeutic ultrasound (TUS) stimulation. However, evidence on its therapeutic benefit is still controversial for many clinical conditions. The aim of this study was to evaluate and to compare the TUS heating distribution on commercially available bone phantoms and in vitro femur a...

After processing, the semiconductor material is cleaved into comparatively small pieces of 1.2mm by 1.4mm. These laser chips contain the important sorting cell as well as two neighboring cells to enable an easier handling of the chip and thus a protection of the lasers. However, due to the small dimensions of the laser chip, there was poor heat dissipation and consequently elevated temperatures...

conclusions the results suggest that the msfc could be used as a simple tool to detect the negative effects of heat in patients with ms. results in the ms group the average msfc scores were -0.48 (sd 0.79) at baseline, -0.99 (sd 1.97) during heat exposure and -0.68 (sd 1.58) after a one-hour delay. the average msfc scores of the hc group were 0.58 (sd 0.42) at baseline, 0.66 (sd 0.43) during he...

Super-absorption” could occasionaly appear when an H/Pd gas-loaded system was heated by an incandescent tungsten filament. The system-pressure was kept on in 10 Pa for several hours without any aid of pumping. In this stage both “excess heat”and “heat after death”was observed once. By calibration, the feature constant of the system was 12.8°C/W in maximum. When the “excess heat”appeared, the sy...

The objective of this work was to obtain degradation kinetic models riboflavin and ascorbic acid, evaluate the potential front-face fluorescence (FFF) spectroscopy predict their concentration in milk after thermal processing. A factorial design with three temperatures (70, 80 90 °C) nine times (from 0 60 min) heat treatment used. Degradation kinetics both vitamins were first order. Predictive u...

background: the homologous recombination (hr) is one of the conventional cloning methods for the production of recombinant dna. it is a quick method for in vivo dna cloning without using the high cost restriction enzymes. a few modifications in the cloning procedure can increase the efficiency of this method. m aterials and methods: in this study, effect of heating on the rate of the igg1 heavy...

A novel maraging steel with vanadium supplement called Specialis® has been developed for additive manufacturing by powder bed fusion using a laser beam. This study characterized this material after processing and post-processing. An intensive process optimization was carried out means of single track melt pool analysis to investigate optimal parameter sets dense parts. Furthermore, the developm...
