Veselá H., Šucman E. (2013): Determination of acrylamide in food using adsorption stripping voltammetry. Czech J. Food Sci., 31: 401–406. A new electroanalytical method for the determination of acrylamide in food has been developed. It was found that a complex of acrylamide and Ni2+ is suitable for the electrochemical determination of acrylamide. Ammonia buffer of pH = 9.5 was found to provide ...

Ultrasonic radiative transfer in polycrystalline media: Effects of a fluid–solid interface" (1995). In previous derivations of the ultrasonic radiative transfer equation ͑URTE͒ for the modeling of multiply scattered diffuse ultrasound in polycrystalline media, the boundary conditions appropriate to experiments performed in a water bath were not used. In the present work, this fluid–solid boundary...

A measuring system evaluating a Point Spread Function generated in an ultrasonographic image by scanning a spherical target was developed. The target is moved in measuring bath filled by water over scanned volume via 3D computer controlled positioning system. A video signal obtained is converted to digital form and analyzed by original software to derive various objective parameters of the imag...

Ultrasound (US), in combination with microbubbles, has been found to be a potential alternative to viral therapies for transfecting biological cells. The translation of this technique to the clinical environment, however, requires robust and systematic optimization of the acoustic parameters needed to achieve a desired therapeutic effect. Currently, a variety of different devices have been deve...

We fabricate ultrasmall phosphorene quantum dots (PQDs) with an average size of 2.6 ± 0.9 nm using a liquid exfoliation method involving ultrasound probe sonication followed by bath sonication. By coupling the as-prepared PQDs with microfiber evanescent light field, the PQD-based saturable absorber (SA) device exhibits ultrafast nonlinear saturable absorption property, with an optical modulatio...

Immersion in hot baths is an infrequently recognized cause of reflex epilepsy. Two such cases are described. Increased awareness of unusual forms of reflex epilepsy is necessary as this may have important prognostic and therapeutic implications.

Nobody, so far as I know, has collated and set down the achievements of physicians from the West Country, though they form a galaxy as bright as any. Our only claim to some of these great men is that they were born in this part of England; but it was in the West Country that others, and not the least distinguished, practised, pioneered and made their names. The best known is surely Edward Jenne...

The influence of ultrasonic pretreatment prior to vacuum drying of Chinese fir specimens was examined in this work. In the pretreatments, wood samples were immerged in a distilled water bath and were treated using two wave frequencies for four different elapsed times to investigate effects of ultrasonic frequency and treatment duration. Then the wood samples were vacuum-dried at 80°C and absolu...
