salmonella     species show different disease syndromes and host specificity, according to their antigenic profile. salmonella enterica serovar typhimurium is one of the most frequently isolated serovar from foodborne outbreaks. poultry meat has been identified as one of the principal foodborne sources of salmonella. in this study, the effect of microwave treatment of chicken meat samples wh...

abstract: the combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. the response surface methodology (rsm) was used to determine the effect of nacl concentration (8%-20%), osmotic solution temperature (25-65°c), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 w) on water loss (wl), solids gain (sg),...

Microwave Plasma Chemical Vapor Deposition (MPCVD) can be used to grow various kinds of diamond films and carbon nanotubes at various temperatures. Issues concerning plasma modeling and control play an important role in MPCVD systems. One crucial factor in controlling the plasma shape and position is the tunable reflected microwave power of the MPCVD system. However, modeling the tunable reflec...

This study evaluates exhausted carbon nanotubes regenerated by desorption processes using 1mM NaOH and microwave irradiation processes. Kinetic analyses of re-adsorption were performed using pseudo first- and second-order models. Regression results revealed that a pseudo first-order model accurately captured re-adsorption kinetics. The regeneration efficiency was 28, 30, 35 and 44% at 18, 28, 3...

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

Gyrotron frequency amplifier has been used for the production of highly charged ion beams with high performance ECR ion sources (ECRIS) for almost 20 years. The widely used technology of microwave power coupling to the high temperature ECR plasma is still a borrowed design from the fusion machines. ECR ion source technologies and physics are advancing over the years, but the interpretation of h...

X-ray diffraction (XRD) was used to investigate the structural and dynamical effects of microwave fields on tetragonal single crystals of hen egg-white lysozyme at a resolution of 2.0 A. Using a modified slab-line waveguide allows on-line XRD to be carried out while the protein crystal is exposed to well defined microwave fields. High microwave power levels mainly lead to increased, but largely...

Title of Dissertation: DESIGN AND FABRICATION OF ON CHIP MICROWAVE PULSE POWER DETECTORS Woochul Jeon, Doctor of Philosophy, 2005 Directed By: Professor John Melngailis Department of Electrical and Computer Engineering On-chip microwave pulse-power detectors are promising devices for many electrical systems of both military and commercial applications. Most research in microwave power detector ...

sno nanoparticles were synthesized using microwave–assisted hydrothermal method. it was noticed that at 300 and 600 watt microwave power, sno formed and remained in the tetragonal phase. at 900 watt, sno2 started appearing and a mixture of sno and sno2 phases coexisted. the particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. the uv-v absorption spectra showed the excitoni...

The velocity-matched distributed photodetectors (VMDP) with high saturation power and large bandwidth have been proposed and demonstrated. The theoretical analysis on the trade-off between saturation power and bandwidth shows that VMDP provides fundamental advantages over conventional photodetectors. The theory for designing and simulating the performance of the VMDP is developed comprehensivel...
