Aiming at the current problems of low excitation efficiency and poor reliability single-rotor hybrid generators, large axial length dual-rotor structure, difficulty in magnetic field analysis, a new type generator topology with high power density is proposed, two rotors side-by-side coaxial, sharing set armature windings, fields do not interfere each other, so analysis optimization can be carri...

This study assessed inhalation exposure to particulate matter (PM₁)-bound mercury (Hgp) and PM₁-bound polycyclic aromatic hydrocarbons (PAHs) among university students. For this purpose, simultaneous indoor (I) and outdoor (O) measurements were taken from two Polish technical universities (in Gliwice and Warsaw) located in distinct areas with respect to ambient concentrations and major sources ...

Regenerative braking can extend the driving range and reduce PM emissions from abrasion for battery electric heavy-duty trucks (BETs). The composite control strategy including torque distribution dynamic coordinated four-axle BET equipped with electromechanical system is studied. A segmented proposed to maximize energy recovery while ensuring stability. simulation results reveal that shows bett...

Particulate matter is defined as a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. Such elements are currently measured utilizing air quality monitoring devices that provide information on PM 10 and PM 2.5 levels giving information on pollution levels. However, many difficulties are encountered in the determination of nanosized ...

Background: The appropriate colon cleansing is a major determinant of quality of colonoscopy. The aim of this study was to compare the efficacy and tolerability of the morning (AM) PEG (polyethylene glycol) solution to previous-evening (PM) PEG solution for the afternoon colonoscopy. Methods: This comparative study compared the AM to PM prep for afternoon outpatient colonoscopy. The subjects r...

Background. Screw-retained restorations are favored in some clinical situations such as limited inter-occlusal spaces. This study was designed to compare stresses developed in the peri-implant bone in two different types of screw-retained restorations (segmented vs. non-segmented abutment) using a finite element model. Methods. An implant, 4.1 mm in diameter and 10 mm in length, was placed in t...
