Research ArticleOpen accessEvery word in the titleColor Doppler Ultrasound Indices in Endometriotic CystsParisa Hajialioghlo, Fatemeh Ghatresamani, Nariman Nezami, Narges SobhaniProblem statement: There have been considerable interests on using non-invasive techniques to detect endometriosis. A few studies were evaluated the Doppler ultrasound findings of endometriosis. This study aimed to characterize the grayscale and Doppler ultrasound findings of endometriosis. Approach: During present prospective study, gray scale and Doppler ultrasound findings of 37 women with final diagnosis of endometriosis were evaluated. Patients … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,803 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffectiveness of Ultrasound on the Destruction of E. coliMohammad H. DehghaniThe aim of this study was to investigate the impact of sonication as a disinfection method for determining the effectiveness of ultrasound waves on the inactivation of E. coli. Ultrasound waves at a frequency of 42 kHz were used to expose aqueous suspension of E. coli. Ultrasound waves display a strong influence on the rate of E. coli disruption in … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,636 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effect of Ultrasound Processing and Exogenous Cellulase Supplementation on the Ruminal Degradability of Palm Date SeedsAhmed Aboragah, Mohammed G. Embaby, Mevlüt Günal, Amer A. AbuGhazalehThe objective of this study was to evaluate the effects of sonication and enzyme supplements on rumen degradability of date palm seeds (DPS). The effect of alkali-assisted sonication and the addition of cellulase enzyme supplements (40 endoglucanase units/g dry matter) derived from Aspergillus niger or Trichoderma longibrachiatum on DPS ruminal degradability were evaluated under in vitro conditions. The in vitro … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 3 · 24 Aug 2019 · 7,419 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Simulation Study of Enhanced Distillation Using Ultrasound Waves for the Separation of Azeotropic MixturesTaha Mahdi, Ammar Emad Al-KawazThe potential of ultrasound waves to enhance distillation system for azeotropic mixture is examined through process flowsheeting using Aspen Plus. Since sonication is not a standard feature in the software library, a mathematical model of the proposed distillation system is developed based on first principles in Aspen Custom Modeler and later exported to Aspen Plus environment for process simulation and … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 2 Jan 2018 · 8,411 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA MODIFIED ADAPTIVE WAVELET SHRINKAGE SPECKLE FILTER FOR ULTRASOUND IMAGESNirmaladevi Periyasamy, Asokan RamasamyThe usage of ultrasound imaging for medical diagnosis is limited due to the presence of speckle noise. In this study Modified Adaptive Wavelet Shrinkage Filter (MAWSF) in the translational invariant domain is proposed for the removal of speckle noise. The adaptive wavelet threshold function removes the fixed bias of soft thresholding. A new inter-scale dependency model is proposed, to perform … …Journal of Computer Science, Vol. 9, Issue 10 · 16 Sep 2013 · 6,539 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,643 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrasound Imaging of the Testes and Accessory Sex Glands in Male Goat Treated with GnRH During Non-Breeding SeasonHamed T. Elbaz, Emad M. Abdel Razek, Ahmed DawodThe aim of the present study was to determine the effect of GnRH on the measurements of testes, accessory sex glands and testosterone hormonal concentrations during the non-breeding season. Eight mature healthy Egyptian Baladi male goat injected with Buserelin acetate (GnRH analogue) 8μg once weekly for one month. Ultrasonographic measurements of the scrotum and its contents and all accessory sex … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 15 Apr 2019 · 7,838 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExtraction Optimization and Antibacterial Property of Total Flavonoids from Zizania Latifolia Bracts and the Effect on Chilled Pork PreservationChen Pan, Shuyi Zhu, Na Niu et al.Zizania latifolia isa widely distributed aquatic vegetable, and its bracts are an agriculturalwaste with a large proportion. In this study, Total Flavonoids of Z. latifoliaBracts (TFZB) were extracted with Ultrasound-Assisted Enzymatic Extraction(UAEE) for the first time, and the extraction process was optimized usingResponse Surface Method (RSM), and compared with other methods. Then, theantibacterial activity of TFZB extracted with optimized UAEE … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 15 Sep 2022 · 6,011 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMass Production of Uniformly Sized Air-Filled Poly-Lactic Acid Microcapsules Made from Microbubble TemplatesJay Molino, Svetlana Jojlova, Hirofumi Daiguji, Fumio TakemuraHollow poly(Lactic Acid) (PLA) microcapsules were fabricated using the bubble template method. In this method, microbubbles nucleated inside droplets of a dichloromethane solution of PLA which were located in a continuous phase of poly(vinyl alcohol). PLA-covered microbubbles formed when PLA adsorbed to the bubble surface by physisorption. Then, the coated microbubbles were spontaneously released from the droplet´s interior into the … …American Journal of Applied Sciences, Vol. 16, Issue 7 · 20 Aug 2019 · 7,756 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTesting by Non-Destructive ControlRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.This paper describes an application of industrial robots that gain ground mainly in the aerospace industry.
