Acrylamide levels in food, and especially in potato products, are perceived world wide as a potential public health problem. The current trials on ‘Rooster’ potato tubers purchased (as ware samples) in a supermarket and fried under domestic conditions showed that soaking (citric acid vs. water) and pre-treatments such as blanching in water and pre-frying in oil were useful for lowering the cont...

Microwave oven generates a harmful electromagnetic wave at 2.45GHz of 1000Watts. The generated microwave is confined within the cavity of the oven for efficient heating and secured operation. To prevent microwave leakage through the front glass door, a special construction of Faraday Cage is involved. In this paper, Faraday Cage is replaced with Transparent Frequency Selective Surface Front Doo...

Matlab-SIMULINK based real time temperature control of oven using different kinds of auto-tuning PID (Proportional-Integral-Derivative) methods is presented in this paper. Ziegler Nichols Step Response Method (P,PI), Relay Tuning Method (P,PI) and Integral Square Time Error (ISTE) disturbance criterion (PI) method are used to control temperature of the experiment set. Controller parameters are ...

The main objective of the study was to compare the effects of halogen lamp–microwave combination baking on quality of breads with other baking methods (conventional, microwave and halogen lamp baking). It was also aimed to improve the quality of microwave baked breads by using combination oven. Weight loss, specific volume, firmness and color of the breads were measured as quality parameters. H...

Oxidation of fats and oils is an important indicator for performance and shelf life of oils. As other vegetable oils, virgin coconut oil (VCO) is not susceptible to lipid oxidation. Thus, a rapid method for quantitative analysis of peroxide value in VCO was developed in this study using Fourier transform infrared (FTIR) spectroscopy coupled with attenuated total reflectance (ATR). Thirty traini...

The present numerical study is conducted to investigate MHD mixed convection flow and heat transfer characteristics in a double-lid driven cavity with a heatgenerating solid square block. The cavity horizontal walls are adiabatic while both the vertical lids are maintained at a uniform temperature Tc and velocity V0. The present study simulates a reasonable system such as air-cooled electronic ...

The mVINIS ion source, a part of FAMA installation at Vinca Institute Nuclear Sciences, is able to produce multiple charged heavy beams through the utilization vapors created by process melting solids inside miniature oven (mini-oven). mini-oven that was used previously could only reach maximum temperature 800?C, which far too low for evaporating most metals. For this purpose, higher operating-...

This paper describes a simple process of adhesive bonding between a glass lid and a SU-8 microfluidic device. The bonding is made by applying pressure, between 1.24 MPa – 3.72 MPa, and heat above the SU-8 glass transition temperature (Tg). The advantages of this process are low cost, simplicity and no need of extra adhesive material, which could block microchannels and inlets. The SU-8 microcha...

A series of experiments was conducted to determine the effects of various factors on Warner-Bratzler shear force measurement of cooked beef. As the extent of thawing of frozen steaks before cooking for shear force evaluation increases (-2 vs 12 degrees C), shear force decreases (P < .05; 7.34 vs 5.99 kg). Location within the longissimus thoracis et lumborum from which steaks were obtained (caud...

In the frame of unification schemes for radio-loud active galactic nuclei (AGNs), FR I radio galaxies are believed to be BL Lacertae (BL Lac) objects with the relativistic jet misaligned to our line of sight, and FR II radio galaxies correspond to misaligned radio quasars. The Ledlow-Owen dividing line for FR I/FR II dichotomy in the optical absolute magnitude of host galaxy–radio luminosity (M...
