  In this research, Sistan sand was used as a natural and inexpensive sorbent for removal of cephalexin and tetracycline antibiotics from water and wastewater samples. For a concentration 60.0 mg L-1 of cephalexin, optimum removal conditions were: pH of the sample 3.0, adsorbent amount 1.0 g, contact time 20.0 min, added amount of sodium chloride to adjust the ionic strength of the solution 7.0 g L-1. Langmuir isotherm was the best...

  - Year 2017

  Assurance cases are developed and maintained in parallel with corresponding system models and therefore need to reference each other. Managing the correctness and consistency of interrelated safety argument and system models is essential for system dependability and is a nontrivial task. The model interface presented in this paper enables a uniform process of establishing and managing assurance case references to various types...

  In this work, we address an everlasting issue in 2 model order reduction (MOR) in electromagnetics that has 3 remained unnoticed until now. Contrary to what has been 4 previously done, we identify for the very first time spurious 5 modes in MOR for time-harmonic Maxwell’s equations and 6 propose a methodology to remove their negative influence on the 7 reduced order model (ROM) response. These spurious modes 8 have nonzero resonance...

  Praca poświęcona jest nadzorowaniu drgań wirujących narzędzi w nowoczesnych frezarkach. Przedmiotem rozważań jest proces frezowania szybkościowego smukłym frezem kulistym na 5-osiowym centrum obróbkowym Deckel Maho DMU 50eVolution. Frezowanie smukłymi narzędziami jest często stosowane w przypadku nowoczesnych centrów obróbkowych. Uzasadnienie technologiczne wynika z konieczności dokładnego wykonywania złożonych kształtów geometrycznych...
