  • Ultrasound assisted extraction

    Publication

    - Year 2017

    The use of green and sustainable extraction techniques is very popular topic in the multidisciplinary area of chemistry, biology and technology. There is no doubt that extraction constitutes a very important step of analytical procedures of separation, detection, identification and determination of wide spectrum analytes from samples characterized by complex and very often nonhomogeneous composition of matrix. Traditional techniques...

    Publication

    - Year 2004

    Oryginalna metoda zastosowana dla wyprowadzenia równaniaewolucyjnego dla ogrzewania środowiska przez falę akustycznądowolnej natury, w tym nieokresowej. Przedstawiono przykłady obliczeń numerycznych.

  • Measurements and Simulations of Engineered Ultrasound Loudspeakers

    Publication

    - Computational Methods in Science and Technology - Year 2015

    Simulation and measurement results of the sound emitted from an ultrasound custom-made system with high spatial directivity are presented. The proposed system is using modulated ultrasound waves which demodulate in nonlinear medium resulting in audible sound. The system is aimed at enhancing the users’ personal audio space, therefore the measurements are performed using the Head and Torso Simulator which provides realistic reproduction...

  • Streaming caused by non periodic ultrasound.

    Publication

    - Year 2003

    Opracowano wzory na generację przepływów rotacyjnych przez falę akustyczną dowolnego typu. Równania ewolucyjne wyprowadzone, wyniki porównywane są teorią dla wielkości uśrednionych. Impuls dodatniej polarności służy przykładem fali akustycznej. Przedstawiono czasowe, przestrzenne wykresy na podstawie obliczeń numerycznych oraz linie pędu przepływu rotacyjnego.

  • Shoulder ultrasound in the diagnosis of the suprascapular neuropathy in athletes

    Publication

    - Open Medicine - Year 2020

    Purpose: Shoulder pain and weakness are common symptoms in athletes who play sports connected with overhead throwing. Suprascapular neuropathy may be one of the reason of such signs.The aim of the study was to find out if ultrasound examination of the shoulder in athletes reveals signs of suprascapular neuropathy. Methods: This was a cross-sectional study in which 67 pro- fessional volleyball, handball and rugby players of polish...
