Research ArticleOpen accessEvery word in the titleImpact of Ultrasonication on Milk Fat Globule Size and Inhibition of Salmonella enteritidis GrowthUmiatin Umiatin, Dalia Sukmawati, Taryudi Taryudi et al.One significant effect of ultrasonic treatment is the inactivation of microorganisms. This characteristic causes ultrasound to be widely used in food processing, healthcare devices, and water treatment. Ultrasonication is an innovative technology that holds promise for accelerating processes and producing high-quality products. The ultrasonic process in milk processing includes homogenization and sterilization. Milk homogenization standardizes fat globule size, while sterilization … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 8 May 2026 · 1,507 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrasonic Microwave Assisted Extraction, Chemical Characterization and Antioxidant Activity of Polysaccharides from Fig LeavesBaikangzhe Zheng, Yang Miao, Yi Zhou et al.This study employed ultrasonic-microwave-assisted extraction (UMAE) to isolate water-soluble polysaccharides from fig (Ficus carica L.) leaves (FLPs). Polysaccharide yield was used as the primary index to evaluate extraction efficiency. The effects of material-liquid ratio, microwave power, extraction temperature, and extraction time on polysaccharide yield were systematically investigated through single-factor experiments, followed by response surface methodology optimization. Structural characterization and antioxidant … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 3 Mar 2026 · 1,671 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Ultrasonic/Microwave Assisted Extraction (UMAE) and Rheological Properties of Polysaccharides from Auricularia polytrichaZe Zhang, Xiao Ding, Ziyi Xu et al.Polysaccharides from Auricularia polytricha (APPS) were extracted using Ultrasonic/Microwave Assisted Extraction (UMAE) technology. UMAE conditions of APPS were optimized with Response Surface Methodology (RSM). Rheological properties of APPS were investigated. The results suggested that the optimal UMAE conditions for APPS were ratio of water to raw material 22 (mL/g), extraction time 15.3 min and microwave power 59W. APPS solution exhibited … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 14 Mar 2020 · 7,420 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Distance Measurement Between Stereo Vision and Ultrasonic SensorSurachai PanichProblem statement: The traditional approaches in mobile robot research are the use of stereo vision systems to extract range information from pairs of images. One of the difficulties of techniques in navigation is that the intrinsic computational expense of extracting three dimensional information from stereo pairs of images. Approach: To compare performance sensor readings from environment between stereo vision and … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,244 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUltrasonic Dental Scaler Performance Assessment with an Innovative CavitometerAntonio Henrique Alves Pereira, Camila Tirapelli, Lucimar Antonio RodolphoProblem statement: There is no specific instrument to test ultrasonic dental scalers used in dentistry. Approach: The aim of this research was to develop and test an innovative cavitometer for quantitative and automatic performance assessments of Ultrasonic Dental Scalers (UDS) through the acoustic emission produced by cavitation induced by the tip of the UDS ultrasonic transducer when immersed in aqueous … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,535 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Microwave and Ultrasonic Pretreatments on Biogas Production from Anaerobic Digestion of Palm Oil Mill EffleuntN. Saifuddin, S A. FazliliProblem Statement: Oil palm production is a major agricultural industry in Malaysia. In 2006, palm oil mills in Malaysia produced more than 58 million tonnes of Palm Oil Mill Effluent (POME). Existing treatment in a series of open lagoons at high ambient temperatures, results in the uncontrolled production of methane and carbon dioxide, which are both green house gases (GHGs). … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,986 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWireless Communication with a Microprocessor Based Ultrasonic Meter for Flow MeasurementsMahmoud Z. IskandaraniProblem statement: Although the traditional metering system and method for controlling flow is generally safe, reliable and robust, it does suffer certain drawbacks, such as limited accuracy and the ability to implement complex reactive rate designs. Hence, there is a need for a circuit and method of increasing metering accuracy, as well as the position control accuracy for variable flow … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,584 accessesView PDFCite
