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 ...

More and more saffron has been cultivated in China because of the increasing saffron demand, but no paper has studied the influence of drying methods on the quality of Chinese saffron. In this paper, three different dehydration treatments applied in actual production were evaluated: dehydration with electric oven, vacuum oven, and microwave. We determined that the highest quality of saffron wil...

In this paper, we demonstrate a food recognition method by monitoring power leakage from a domestic microwave oven. Universal Software Radio Peripheral (USRP) is applied as a low-cost spectrum analyzer to measure the microwave oven leakage as received signal strength indication (RSSI). We aim to recognize 18 categories of food that are commonly cooked with a microwave oven. By analyzing 180 fea...

Drying Blower Oven technology by testing the feasibility to be seen with tests such as nutrient content test, ash water organoleptic test marketing test. Testing of is carried out raw material product, red chili. using at a temperature 32.2˚C 54.2˚C wind speed 12 m/s until below 8% - 10%. This study aims determine drying characteristics chili Multioven Cabinet Type changes in temperature, relat...

introduction: since discovery of high frequency waves, their biological effects have been in great attention. increased male fertility problems proposed their possible relation to use of microwaves. testes are of very active body tissues, which can be affected by these waves. age of exposure may also be an important factor. methods: this study was carried out to evaluated testosterone level in ...
