Thermoduric bacteria are organisms capable of surviving the industrial pasteurization process of milk, and can carry over into product causing quality defects, or creating health hazards. The various species of genus Bacillus, Microbacterium, Micrococcus, Enterococcus, Lactobacillus and Corynebacterium are described as heat resistant species (Marth and Steele, 2001). A thermoduric bacterium in ...

rier for a variety of edible antimicrobial agents. Technologies designed to pasteurize processed meats after final packaging have received copious attention. Post pasteurization of vacuum packaged cooked products consists of hot water or steam immersion followed by immediate chilling. Irradiation (gamma, electron beam or X-ray) of cooked vacuum or MAP packaged products can produce very acceptab...

We achieved low-resistance nonalloyed Ohmic contacts for n-type GaN using selective area growth (SAG) by plasma assisted molecular beam epitaxy (PAMBE). Thus-fabricated high electron mobility transistor (HEMT) demonstrated comparable or more favorable electrical performance than the conventional alloyed counterpart. Meanwhile, the nonalloyed PAMBE-SAG technique avoids problems created by the hi...

Schottky diodes are fabricated on n-Aluminium Gallium Arsenide / Gallium Arsenide (n-AlGaAs/GaAs) high-electron-mobility-transistor (HEMT) structure due to availability of high electron mobility and capability of fast switching performance. The processing steps used in the fabrication are the conventional steps used in standard GaAs processing. The ohmic and Schottky contacts of Schottky diodes...

In present scenario high voltage AlGaN/GaN High Electron Mobility Transistors (HEMTs) on Si substrate with Schottky drain contacts were simulated to increase the breakdown voltage by replacing the conventional Ohmic drain contacts. A significant increase in breakdown voltage values was achieved for nonannealed Schottky contacts by elimination of metal spikes underneath drain electrodes. The bre...

Crevice corrosion material loss is often most severe at intermediate distances into the crevice. This intermediate attack can be rationalized using the ohmic drop model of Pickering if and only if the material in question exhibits active/passive behavior in the crevice environment. Conventional theories that ascribe control of crevice corrosion to chemical changes exclusively cannot rationalize...

This paper presents a model predictive control (MPC) of a pasteurization pilot plant based on an LPV model. Since not all the states are measured, an observer is also designed, which allows implementing an output-feedback MPC scheme. However, the model of the plant is not completely observable when augmented with the disturbance models. In order to solve this problem, the following strategies a...

Conventional metasurface holograms relying on metal antennas for phase manipulation suffer from strong Ohmic loss and incomplete polarization conversion. The efficiency is limited to rather small values when operating in transmission mode. Here, we implement a high-efficiency transmissive metasurface hologram by leveraging the recently developed Huygens' metasurface to construct an electric and...

In this paper we propose a new equivalent circuit model of organic light emitting device (OLED). The physicalbased model is considering the effect of high built-in voltage existing between the organic materials and the effect of non-ideal ohmic occurring at the contact between metal and organic. Compared with the measured IV data of RGB OLED samples and the result of conventional OLED model, th...
