Ultrasounds interact

Ebook "Ultrasonic production of nano-emulsions for bioactive delivery in drug and food applications" provides an overview of ultrasonic emulsification and an update on recent advances in developing stable emulsions for the creation of novel drugs and functional foods, with a focus on bioactive delivery in these products. The interaction of ultrasound with the hydrocolloids and biopolymers that are often used to stabilize emulsions can offer advantages such as improved stability or greater control of formed droplet size distributions.

Ebook "Ultrasonic synthesis of functional materials" begins by giving a summary of sonochemistry and explains how a chemical reaction can be induced by the interaction of sound waves and gas bubbles in liquids. The work outlines how primary and secondary radicals combined with the physical effects generated during acoustic cavitation are active in the ultrasonic synthesis of a variety of functional materials.

The crystalline structure-magnetic behaviour relationships of the nanomaterials were investigated to imply the presence of a surface protection at nanoscale. The speculation indicated that shock waves took place as the surface-protective role rather than the original mechanical interaction of ultrasound with a larger scope of impact.

Lung ultrasound (LUS) is nowadays a fast-growing field of study since the technique has been widely acknowledged as a cost-effective, radiation free, and ready available alternative to standard X-ray imaging. However, despite extensive acoustic characterization studies and documented medical evidences, a lot is still unknown about how ultrasounds interact with lung tissue.

Tài liệu present: the use of acoustic energy in food or bioprocessing operations is a relatively new endeavor if compared with other sources of energy, such as mechanical or thermal, which have been utilized for centuries in various applications. There are two important factors that make the current ultrasound-assisted processes possible. One is related with the development in ultrasound generation technology and the other one is the better understanding of interactions between acoustic energy and liquid media, enabling the development of important guidelines for ultrasound-based processes.

Techniques for non-invasive Breslow determination use either mechanical or electromagnetic waves. A wave is the propagation of a perturbation inducing reversible variations of local physical properties. It transports energy but no matter. Ultrasounds and optical waves are used mainly because of their innocuousness. In the next paragraphs, ultrasonography then several optical techniques will be developed. Basic physical principles of each type of wave interaction with skin will be described then accuracy of Breslow index determination by such techniques will be given.

Arterial CO2 tension is a powerful modulator of cerebral vascular calibre, CBF and ICP (12-15.) While the mechanisms are incompletely understood, CO2 relaxes pial arterioles by interactions between the endothelium, vascular smooth muscle, pericytes, adjacent neurons and glial cells. Studies supported that cerebral vessels are sensitive to changes in extracellular pH, rather than a direct response to CO2 or bicarbonate. In the limits of physiological PaCO2, 20-60 mmHg, the relationship between PaCO2 and CBF is linear.
