To determine whether microwave (MW) radiation induces neural cell apoptosis, differentiated PC12 cells and Wistar rats were exposed to 2.856 GHz for 5 min and 15 min, respectively, at an average power density of 30  mW/cm². JC-1 and TUNEL staining detected significant apoptotic events, such as the loss of mitochondria membrane potential and DNA fragmentation, respectively. Transmission electron...

Microwave (MW) drying is a rapid dehydration technique that can be applied to specific foods. Increasing concerns over product quality and production costs have motivated the researchers to investigate and the industry to adopt microwave drying technology. The advantages of microwave drying include the following: shorter drying time, improved product quality, and flexibility in producing a wide...

This study is aimed to the comparison of the sensitivity of linear spectral asymmetry index (SASI) and nonlinear Higuchi’s fractal dimension (HFD) methods for detecting modulated microwave effect on human electroencephalographic (EEG) signal at non-thermal level of exposure. The experiments were carried out on a group of 14 healthy volunteers exposed to 450 MHz microwave radiation modulated at ...

This research was carried out to assess the dechlorination and decomposition of Polychlorinated biphenyls (PCBs) in the real waste transformer oil using polyethylene glycol 1000/NaOH through a modified household microwave oven. To do so, the influence of polyethylene glycol (PEG) (1.5-7.5 g) and NaOH (0.3-1.5 g) under microwave (MW) power of 500 W on the dechlorination efficiency of PCBs, exist...

A novel approach to computational microwave optimization is presented, namely, a neural network procedure controlling full-wave FDTD simulation of the structure. A radial-basis-function network is trained by geometrical parameters and the computed frequency responses of S-parameters. Computational efficiency of the procedure is illustrated for a waveguide T-junction with a post, a slotted waveg...

in this research, microwave-assisted hydrodistillation (md) with pretreatment ultrasound (us) 45 and 90 min of essential oils from fresh aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (hd) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. all experiments were performed ...

Atrial fibrillation (AF) is associated with a significant mortality and morbidity. Microwave (MW) ablation is a new technology for surgical treatment of this arrhythmia. We present our preliminary experience with MW ablation in patients with AF who underwent a concomitant open-heart surgery. From October 2001 to March 2002, a total of 10 patients underwent MW ablation of AF and an open-heart su...

Drying is one of the methods used for preserving fruits and vegetables. However, due to lengthy process elevated temperature convective drying, other pretreatment drying are studied shorten time obtain high-quality products. This study aimed examine effect ultrasonic (US) microwave–hot air (MW–HA) on time, specific energy (SEC), qualitative properties (e.g., color, shrinkage, rehydration ratio)...

Metal-ceramic coaxial cable Fabry-Pérot interferometric (MCCC-FPI) sensors have been developed using a stainless steel tube and a stainless steel wire as the outer and inner conductors, respectively; a tubular α-alumina insulator; and a pair of air gaps created in the insulator along the cable to serve as weak reflectors for the transmitting microwave (MW) signal. The MCCC-FPI sensors have been...

The problem of soot emissions from diesel engines is introduced and the possible solution of combining doped perovskites and microwave (mw) irradiation to "clean up" diesel soot filters is outlined. Eighteen doped perovskite catalysts are synthesized and tested for propane and CO oxidation, which are taken as model components for soot. The activity, selectivity, and SO2 tolerance are compared u...
