background: with the technical development, ultrasound tends to overpass its limits and to become the main investigation tool even for situations when it was traditionally considered second best. it is more convenient both for patient and doctor, less expensive and has real diagnostic value. objective: the present paper, and its graphic back-up, are intended as a visual testimony of the fact th...

Since the rose water is used in food, pharmaceutical, and cosmetic products, its microbiological control is necessary. Conventional pasteurization methods cause undesirable changes in taste, smell, medicinal properties and nutritional value with decreasing the amount of essential oil, because of high temperatures. In this study, the effects of the microwave power, temperature, ultrasound power,...

      Background: Computed tomography scans (CT scan) and X-rays are used to diagnose paediatric maxillary sinusitis. This study aimed at exploring the diagnostic value of the conventional and colour Doppler ultrasounds and their specific findings in cases of paediatric sinusitis.    Methods: A total of 60 children diagnosed with sinusitis were included in this s...

Ultrasound-assisted extraction (UAE) was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of curcuminoids from turmeric plant rhizomes. The turmeric samples were extracted under indirect sonication in an ultrasonic bath, and compared with the conventional methods. It was found that the yield of ultrasound-assisted extraction was approxim...

In this investigation a simple synthetic method for the synthesis of trifluoromethyl-1H-benzo[e][1,2,4]triazolo[1,2-a][1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo [5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones has been developed using urazole or phthalazine and aceteimidoyl chloride derivatives at room temperature under ultrasound irradiations. In the comparison to the conventi...

in this research,the effect of power ultrasound (20 khz ,800 and 1000w) at 20.40 and 60 minutes on physico-chemical properties of two rice varieties tarom and neda was investigated and by the soaking method in controlled temperature (47°c) compared.results showed the maximum amount of water absorption of rice, observed at 60 minutes ultrasound treatment (1000w) and the lowest was observed in co...
