We have characterized the effects of ultrasound on fibrinolysis in vitro to investigate the mechanism of ultrasonic potentiation of fibrinolysis and to identify potentially useful ultrasound parameters for therapeutic application. Radiolabeled clots in thin walled tubes were exposed to ultrasound fields in a water bath at 37 degrees C, and lysis was measured by solubilization of radiolabel. Ult...

Switchgrass is a perennial C4 plant with great potential as a bioenergy source and, thus, a high demand for establishment from seed. This research investigated the effects of ultrasound treatment on germination and seedling growth in switchgrass. Using an orthogonal matrix design, conditions for the ultrasound pretreatment in switchgrass seed, including sonication time (factor A), sonication te...

Nucleation of ice during freezing is an important phenomenon affecting the probability distribution of the ice crystal size and crystal growth. Power ultrasound has been proved to be useful in promoting the nucleation of ice in water based solutions. In the present work, the use of ultrasound waves to induce dynamic nucleation was studied on deionized water, 8% sucrose solution, and agar gel sa...

OBJECTIVE Ultrasound guidance can increase success with peripheral nerve blocks. Accurate anesthetic injection is optimized with both clear visualization and fine adjustment of the needle tip at the target area. Good needle alignment with the ultrasound beam and using a freehand technique are both desirable for these conditions. The purpose of this report is to describe how a unique, in-plane l...

conclusions it is suggested that the training of nonpharmacological methods to improve sleep quality such as reflexology and foot bath be included in the elderly health programs. in addition, it is recommended that the impact of these interventions on subjective sleep quality using polysomnographic recordings be explored in future research. background sleep disorders are common mental disorders...

Background/introduction High intensity focused ultrasound (HIFU) ablation of the brain has been increasingly used as a non-invasive treatment for essential tremor and neuropathic pain. However, artifacts arise in magnetic resonance (MR) images as a result of dielectric properties of the water bath coupler and of the tissues being investigated. As radio frequency (RF) waves enter a dielectric me...

Enzymes are important in biological wastewater treatment systems, since they are responsible for breakdown of macro- and micropollutants, thereby making the pollutants available for metabolism. Enzyme activity has been investigated in particular in activated sludge processes, since the activated sludge technology is the most important and widely spread wastewater treatment technology used today...

public bathes have much importance in islamic cities, after the most significant structures like mosques and schools. there are a number of factors affecting the construction of bathes among which temperature regulation, humidity, access path, location in the urban texture, watercourses, and construction of exit paths are the most important. this study tries to make a comparative analysis of t...

Plant nutrients extracted from sustainable sources, namely Alaria esculenta and Lemna minor, have been evaluated for their nutritional value in an attempt to identify potential as protein-rich sources. The implementation of green technologies such high-power ultrasound extract these alternative biomasses was studied compared more traditional techniques. Probe sonicators fared better than bath e...

The effect of ultrasound in combination heat on the extraction yield and technological properties chia seed mucilage was investigated. Chia seeds were mixed with distilled water at a seed-to-water ratio 1:30. dispersion adjusted to pH 9 treated either by bath or heat/ultrasound probe-type sonication 50 °C 80 for 30 60 min. samples evaluated. gave greater (6.92–10.52%) as compared (1.03–1.86%). ...
