Incorporation of high intensity ultrasound (HIU) to a scraped surface heat exchanger: Effect of HIU position
The objective of this work was to introduce high-intensity ultrasound (HIU) in different positions within a scraped surface heat exchanger (SSHE) and evaluate the crystallization behavior and physical properties of a low saturated, soybean-based fat. The SSHE in this study was composed of one pump (flow rate of 11 L/h), two crystallization barrels (32 °C, 344 rpm), and one pin worker (208 rpm). HIU was placed before the first crystallization step, or barrel 1 (HIU-0), between the two barrels (HIU-1), between barrels 2 and the pin worker (HIU-2) and after complete crystallization in the SSHE (HIU-3). HIU amplitudes of 20% or 50% using 5-s pulses were used. Physical properties of the crystallized material such as microstructure, solid fat content, oil binding capacity (OBC), viscoelasticity, hardness, and melting behavior were evaluated. HIU induced crystallization and improved all physical properties when positioned at HIU-2 and HIU-3 using 50% amplitude, but in HIU-3 the effect was more pronounced than in HIU-2. Samples sonicated using 50% amplitude at HIU-3 position showed the following improvements (p
Conclusion: Micro-ultrasound is a more convenient and cost-effective method in real-time imaging during the biopsy procedure in detecting clinically significant prostate cancer. Although micro-ultrasound has shown promising results, more clinical data and comprehensive analysis are still needed.
ConclusionEmergency physicians should know about this potential complication as an important differential diagnosis resulting from acute abdominal complaints in patients with ventriculoperitoneal shunts.
A Kentucky law requiring doctors to perform ultrasounds and show fetal images to patients before abortions was upheld Monday by the U.S. Supreme Court.
Resumo O aneurisma de art éria poplítea (AAP) é o mais frequente dos aneurismas periféricos, correspondendo a 85% do total de aneurismas. Normalmente, são assintomáticos, e o diagnóstico, em geral, é feito por meio do exame físico, tendo uma maior incidência no sexo masculino e em idosos. São bilaterais em 50% dos casos e, em 60% das vezes, estão associados a aneurisma de aorta abdominal. Apresentamos um paciente do sexo masculino com 72 anos de idade, com duas massas pulsáteis em ambas as regiões poplíteas, assintom&aac...

The U.S. Supreme Court on Monday left in place a Kentucky restriction requiring doctors to show and describe ultrasound images to women seeking an abortion, turning away a challenge arguing that the measure violates the free speech rights of physicians.
