environmental contamination, which is growing around the world, is a serious problem can not to be neglected. among all contaminations, water pollution is a major problem. azo dyes are one of the largest groups of pollutants found in the drinking water, coming from, and the food and textile industries. tio2/fe3o4 and tio2/fe2o3 nanocomposites with various ratios were synthesized by an ultrasoni...

This paper mainly studied the extraction process of traditional Chinese medicine Aristolochia mollissima Hance (Aristolochiaceae) and the inhibitory effect of its extracts on osteosarcoma HOS cells. The extraction process included the ultrasonic extraction method, heat reflux method and decoction method to obtain three different extracts. MTT assay was used to test the effect of the extracts on...

it has been proved that ultrasonic energy can considerably increase the amount of oil recovery in animmiscible displacement process. although many studies have been performed on investigating theroles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluatewave attenuation parameter, which is an important parameter in the determination of the energydel...

Tonsillectomy is old surgical procedure that has evolved to a more safe method that has lesser complications with little or no morbidity and mortality. Aim: this was comparative study which compared the old dissection tonsillectomy method and the newer method of tonsillectomy (ultrasonic scalpel and Laser tonsillectomy method). Methodology: Equal number of patients both in age and sexes had con...

This paper describes the investigation for the feasibility of inspection of steel-rocasin rubber specimen used in rocket motor for detection of debond by using air-coupled ultrasonic. A pair of high performance air-coupled transducers was used to generate and receive the high intensity ultrasonic pulses. Probes were placed at the opposite side of the specimen during inspection. It was shown tha...
