Article Abstract

The ultrasonic appearances of three cases of renal venous thrombosis are shown. Initially the kidney is enlarged, echogenic and shows echogenic streaking that has a vascular or perivascular distribution. Subsequently thrombosis of renal veins or the inferior vena cava may be demonstrated and ultimately the kidney may recover or atrophy. The ultrasonic appearances will depend on the severity of the thrombosis and the stage at which the examination is performed.

Ultrasound shear wave elastography (SWE) is widely used in clinical applications for non-invasive measurements of soft tissue viscoelasticity. The study of tissue viscoelasticity often involves the analysis of shear wave phase velocity dispersion curves, which show how the phase velocity varies with frequency or wavelength. In this study, we propose an alternative method to the two-dimensional Fourier transform (2D-FT) and Phase Gradient (PG) methods for shear wave phase velocity estimation.

Inspection of wind turbine bolted connections using the ultrasonic phased array system.

Heliyon

July 2024

Centre for Ultrasonic Engineering, Department of Electronic and Electrical Engineering, University of Strathclyde, Glasgow, G1 1XQ, UK.

This study explores the inspection of bolted connections in wind turbines, specifically focusing on the application of Phased Array Ultrasonic Testing (PAUT). The research comprises four sections: Acoustoelastic Constant calibration, high tension investigation on bolts, blind tests on larger bolts, and Finite Element Analysis (FEA) verification. The methodology shows accurate results for stress while the bolt is under operative loads, and produces a clear indication of when it is above these loads and beginning to deform.

Laparoscopic cholecystectomy is a widely performed procedure, with securing the cystic duct being a critical step to prevent bile leakage. Traditional metal clips are commonly used, but alternative methods, such as non-absorbable polymer clips, absorbable clips, sutures, and ultrasonic shears, are also utilized. This systematic review and meta-analysis evaluates the safety and efficacy of various cystic duct securing techniques.

Role of calcination process of natural colemanite powder on compressive strength property of concrete.

Heliyon

January 2025

Department of Civil Engineering, Faculty of Engineering and Architecture, Recep Tayyip Erdogan University, 53100, Rize, Turkey.

The use of boron minerals as an additive is important in terms of reducing CO emissions and providing input to the economy. Sustainable natural colemanite was subjected to calcination at 550 °C in order to concentrate the amount of BO. For the characterization of calcined mineral, XRD, TGA/DTA, and BO component tests were carried out.

Protein concentrate (PC) is a potential solution to address the global protein shortage, with Indonesian shortfin eel being a suitable raw material. This research investigates the impact of ultrasound pretreatment and extraction parameters on the nutritional quality of eel protein concentrate (EPC). The study involved ultrasonic pretreatment at different times and power, and solvent extraction with different solvents, temperature, and solvent-solid-feed-ratio (SSFR).
