Opis:
Many imaging techniques are playing an increasingly significant role in clinical diagnosis. In the last years especially noninvasive electrical conductivity imaging methods have been investigated. Magnetoacoustic tomography with magnetic induction (MAT-MI) combines favourable contrast of electromagnetic tomography with good spatial resolution of sonography. In this paper a finite element model of MAT-MI forward problem has been presented. The reconstruction of the Lorentz force distribution has been performed with the help of a time reversal algorithm.

Opis:
The aim of the study was to determine the effect of high voltage electrical stimulation (330 V, 17 Hz, 120 s) of beef half-carcass and heat treatment on tenderness and water holding capacity of meat. The experimental material was a semimembranosus muscle derived from Polish Holstein-Friesian heifers (n=12). In the experiment, a forced and natural air circulation ovens were used; the raw material was heated at 170ºC to obtain a final temperature from 55 to 80ºC inside the beef. Results showed that electrical stimulation improved tenderness of roasted beef, which was demonstrated in the decrease in the maximum shear force from 39 to 26%. The electrical stimulation had a negative effect on cooking losses during roasting and water content in the final product. It has also been shown that studied quality attributes of beef depends on the type of heat treatment. Beef prepared in forced air circulation oven, were characterized by lower water content and higher values of maximum shear and compression forces than those heated in natural air circulation oven

Opis:
The paper presents the design process of a radial-axial turbine working with SES36 working fluid. First, the mean-line design process is performed and then the geometry is developed. In the next stage the numerical verification is performed taking into account the real properties of the working fluid. The properties are implemented via a look-up table and by a modified Benedict-Webb-Rubin equation of state. The presented turbine is characterized by a very small stator outflow angle which is about 4.5◦ but despite this small value, the efficiency of the machine is relatively high and equal to about 88%. The influence of internal leakages has also been investigated.
