One of innovate techniques that was used for improvement of water treatment process is application of ultrasound waves. In this study, different applications of ultrasound technology in water treatment process such as membrane filtration, turbidity and total suspended solid reduction, algae removal, disinfection process, water softening process and other pollutants removal such as halomethanes ...

Ultrasound is an innovative technology that is used successfully for sonochemical synthesis, deagglomeration, dispersion, emulsifying, functionalization and activation of particles. Particularly in nanotechnology, the ultrasonication is an essential technique for the synthesis and processing purposes of nano-size materials. Since nanotechnology has gained this outstanding scientific interest, n...

A simple but highly accurate irradiation method for the "conservative" treatment of retinoblastoma has been developed at the Utrecht Retinoblastoma Centre. Treatment is carried out with a 6 MV or 8 MV linear accelerator using a lateral D-shaped field of 26 X 32 mm2. This D-shaped field is specially contoured to include the entire retinal surface or vitreous and 10 mm of the anterior optic nerve...

OBJECTIVE To assess whether non-surgical periodontal treatment is associated with changes in serological markers of systemic inflammation. MATERIALS AND METHODS Thirty-five systemically healthy subjects with severe generalized periodontitis meeting the inclusion criteria participated in a four-month single blind interventional trial of which thirty-two completed the study. Periodontal paramet...

The aim of this study was to evaluate the root surface defect produced by hand curettes and ultrasonic tips with different power settings. Forty root surfaces were divided into 4 groups according the treatment: Gracey curettes, ultrasonic scaler at 10% power, ultrasonic scaler at 50% power and ultrasonic scaler at 100% power. Each specimen was instrumented with 15 strokes and the and divided in...

OBJECTIVE To evaluate regenerated articular cartilage quantitatively by introducing an ultrasonic probe into the knee joint under arthroscopy and analysing the A-mode echogram by means of wavelet transformation. METHODS Three experimental rabbit models (spontaneous repair model, large cartilage defect model, treatment model) were examined using our ultrasonic evaluation system and a histologi...

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...

Background:  After breast conserving surgery, most recurrences occur around the primary tumor site. This justifies the use of boost radiotherapy to the primary site of tumor. Surgical scar is not always a good surrogate for the location of the lumpectomy cavity. The aim of this study was to evaluate ultrasonic guidance for detection of the lumpectomy cavity after breast conserving surgery ...

We examined the effects of ultrasound and Fenton reagent on ultrasonic coupling Fenton oxidation (U+F) pre-treatment processes for the disintegration of wastewater treatment plant sludge. The results demonstrated that U+F treatment could significantly increase soluble chemical oxygen demand (SCOD), total organic carbon (TOC), and extracellular polymeric substances (EPS) concentrations in sludge...

The purpose of our study is to analyze the clinical, ultrasonic, microbiologic, and histopathologic characteristics, management, and outcomes in a series of primary canaliculitis with concretions patients who underwent canaliculotomy with curettage.Thirty-six patients were reviewed for age, sex, location and laterality, duration of symptoms, clinical symptoms, ultrasonic signs, result of microb...
