in this search drying characteristics of green pea (pisum satium) with an initial moisture content of 76% (db) was studied in a fluidized bed dryer assisted by microwave heating. four drying air temperatures (30, 40, 50 and 60ºc) and five microwave powers (180, 360, 540, 720 and 900w) were adopted. at each drying operating conditions the volume of green pea was calculated by measuring the three...

Nixtamalization is the process of steeping dried corn in hot water with calcium hydroxide (lime). The resulting product, called nixtamal, is further processed into tortillas, a staple in the Mexican diet. Corn tortillas are prepared directly from nixtamal, from nixtamalized corn flour, or from a mixture of the two. A technology for adding micronutrients to fresh nixtamal tortillas is discussed....

Recent years many authors reported thermal anomaly change around epicenter before earthquake. Some researchers tried to predict the earthquake based on the analysis on the temperature anomaly feature by using satellite thermal infrared data. However the infrared radiation can not pass through the thick-layer cloud, so as to hardly achieve the earthquake monitoring. Microwave is also a kind of t...

This study was conducted in an attempt to characterize some of the effects of sublethal microwave radiation on cells of Staphylococcus aureus. Cultures were exposed to microwave radiation for 10, 20, 30, and 40 s. The effects of a conventional heat treatment were also compared by placing flasks containing cultures in a boiling water bath for the amount of time required to reach temperatures equ...

In recent years, various types of applications of electromagnetic techniques for microwave thermal therapy have been developed. Among them, minimally invasive microwave thermal therapies for cancer are of great interest. They are interstitial microwave hyperthermia and microwave coagulation therapy. In this paper, we describe the characteristics of thin coaxial antennas for those therapies.

Microwave ovens and 802.11 both use the unlicensed 2.4GHz ISM (Industrial Scientific Medical) band. Microwave ovens use this frequency to heat while 802.11 uses this for communication. The use of microwave ovens in the vicinity of an 802.11 node therefore naturally affects the node's ability to communicate. In this project we investigate how microwave oven noise interacts with 802.11 communicat...

The microwave power transmission is an approach for wireless power transmission. As an important component of a microwave wireless power transmission systems, microwave rectennas are widely studied. A rectenna based on a microstrip dipole antenna and a microwave rectifier with high conversion efficiency were designed at 2.45 GHz. The dipole antenna achieved a gain of 5.2 dBi, a return loss grea...

Public concerns over possible adverse effects of microwave radiation emitted by mobile phones on health are increasing. To evaluate the intensity of oxidative stress, cognitive impairment and inflammation in brain of Fischer rats exposed to microwave radiation, male Fischer-344 rats were exposed to 900 MHz microwave radiation (SAR = 5.953 x 10(-4) W/kg) and 1800 MHz microwave radiation (SAR = 5...

A rapid and efficient method for the synthesis of bis-thiazolidinones has been achieved by pseudo five-component reaction of aldehydes, ethylenediamine and thioglycolic acid in the presence of nano-NiZr4(PO4)6 as catalyst under microwave irradiation. Nano-NiZr4(PO4)6 has been characterized by powder X-ray diffraction, scanning electronic microscopy (SEM), energy dispersive spectroscopy (EDS), v...
