A forced convection gas-fired oven has been designed which will sterilize a very heavy load of syringes and instruments and containers. It is superior to a gas-fired, infrared, radiant-heated oven which was designed for sterilizing syringes.

OBJECTIVE This study observed the effects of cooking method and final core temperature on cooking loss, lipid oxidation, aroma volatiles, nucleotide-related compounds and aroma volatiles of Hanwoo brisket (deep pectoralis). METHODS Deep pectoralis muscles (8.65% of crude fat) were obtained from three Hanwoo steer carcasses with 1+ quality grade. Samples were either oven-roasted at 180°C (dry ...

Experimental details Preparation of Fe3O4 micro-spheres The mono-dispersed Fe3O4 micro-spheres were synthesized by a one-pot hydrothermal method. In a typical synthesis, FeCl3.6H2O (0.54 g), sodium citrate (1.2 g), and urea (0.2 g) were dissolved in distilled water (40 mL). Then, PAAS (0.2 g) was added under continuous stirring until it was totally dissolved. The solution was transferred to a 5...

The film formation of an acrylate latex with a glass-transition temperature of 38 °C has been achieved through the use of near-infrared (NIR) radiative heating. A hard, crack-free coating was obtained without the addition of plasticizers. Sintering of acrylate particles was confirmed through measurements using atomic force microscopy. The addition of an NIR-absorbing polymer increased the rate ...

The fibers of oil palm empty fruit bunch (OPEFB) stalks were investigated to determine the changes in their basic properties after oven-heat treatment. The oven-heat treatment was conducted at 100 °C or 190 °C for 15 min. There were slightly noticeable morphological, chemical, and thermal alterations in oven-heat treated OPEFB stalk fibers for short duration. Scanning electron microscopy (SEM) ...

Electromagnetic disturbances emitted from microwave ovens may cause serious interference with Bluetooth systems in the 2.4 GHz ISM (Industrial, Scientific and Medical) band. In this paper, the bit error rate (BER) performance of Bluetooth systems interfered by microwave oven noises is analyzed using a microwave oven noise model which consists of FM periodic tone-bursts. Employing Bennett’s meth...

The objective of this study was to determine the effect of oven and traditional roasting on the polyphenol content, antioxidant activity, lipid quality, proximate composition and mineral content of fermented cocoa beans. Results showed that traditional roasting significantly decrease (p < 0.05) the polyphenol content and antioxidant activity of cocoa beans. The analysis of oil showed that oven ...

Microwave oven can safely be used in microbiology laboratory for preparation of media. The method is convenient, reliable, economical and reproducible. It saves time and the quality of media is superior as compared to media prepared by conventional autoclaving method.

OBJECTIVE The aim was to assess the significance of two biomarkers; antibody to benzo(a)pyrene DNA adducts and concentration of hydroxyethylvaline haemoglobin adducts in samples from a well studied group of coke oven workers. As a measure of exposure we have used 1-hydroxypyrene in urine. METHODS Urine and blood samples were collected from coke oven workers and a control group. Samples from c...

This study was conducted to determine that carrot powder obtain by different drying methods (oven and vacuum-freeze dryer) of carrot unfit for human consumption that whether feed additives in animal nutrition or not. Carrots randomly divided 2 groups. First group was dried by using oven, second group was by using vacuum freeze dryer methods. Dried carrot prepared from fresh carrot was analysed ...
