introduction: potato is raw food stuff with high popularity worldwide when deep fried. deep frying is a fast budget process used for preparing savory food. in this process, oil is used both as a heating intermediate and as an ingredient producing calorific products. nutrition has become a major health concern, particularly in developmental countries where obesity has turned into an ever-increas...

We demonstrate burst-mode operation of a polarization-maintaining Yb-doped fiber amplifier. Groups of pulses with a temporal spacing of 10 ns and 1 kHz overall repetition rate are amplified to an average pulse energy of ∼20 μJ and total burst energy of 0.25 mJ. The pulses are externally compressed to ∼400 fs. The amplifier is synchronously pulsed-pumped to minimize amplified spontaneous emissio...

Little is known about the efficacy of pulsed ultrasound compared with continuous ultrasound. Previous studies on the efficacy of pulsed ultrasound were not systematic and gave different results. In this study, the effects of pulse length, pulse interval, pulse length × pulse intervals, and treatment time on sonochemical activity were investigated using a simple oxidation of iodide method and a ...

In this study, we examine mutagenicity of 2, 10 and 20 kHz, 0.8mT intermediate frequency magnetic fields (IF-MFs) by mouse lymphoma assay (MLA) using L5178Y tk3.7.2c cells. The result shows that no significant increase or decrease in mutation frequency by exposure to any IF-MFs. In addition, no significant difference was observed in colony formation such as shape or frequency of large and small...

OBJECTIVES The purpose of this study was to obtain behavioral hearing thresholds for frequencies between 0.125 and 20 kHz from a large population between 10 and 65 yr old using a clinically feasible calibration method expected to compensate well for variations in the distance between the eardrum and an insert-type sound source. Previous reports of hearing thresholds in the extended high frequen...

Reliable ignition in high-speed flows represents a significant scientific problem with a wide range of practical applications. Scientifically, the ignition processes involve complicated interactions among various aspects of chemical reaction and turbulence, which are not fully understood yet [1]. Reliable ignition in propulsion and power devices is further complicated by practical factors such ...

This article describes a discrete-time zoom analog-to-digital converter (ADC) intended for audio applications. It uses coarse 5-bit SAR ADC in tandem with fine third-order delta-sigma modulator (ΔΣM) to efficiently obtain high dynamic range. To minimize its over-sampling ratio (OSR) and, thus, digital power consumption, the employs 2-bit quantizer and loop filter notch. In addition, an extra fe...

Recently several investigators reported on various devices of generating cold plasma jets at atmospheric pressure. A pulsed source developed and reported, the pencil, is one them. This device capable a plume centimeters in length using DC high voltage source. In this study, kHz alternative current (18 kV-15 kHz) was applied to electrodes similar electrode system pencil instead direct pulse 2-3 ...

A 64 kbps coder of wideband (15 kHz) monophonic audio signals is described. Its structure is based on the transform coded excitation scheme, adopted to 7 kHz band signals. Significant modifications are proposed, that yield the reduction of delay while keeping an almost transparent quality of speech and music, equivalent to that provided by the MPEG1, layer II audio standard at the same bit rate...
