This study analyzed the effects of irradiation polytetrafluoroethylene (PTFE) containing 40% bronze using an electron beam with energy 10 MeV. Dosages from 26 to156 kGy (2.6–15.6 Mrad) were used. The impact a high-energy on thermal, spectrophotometric, mechanical, and tribological properties was determined, results compared those obtained for pure PTFE. Thermal studies showed that such caused changes in melting temperature Tm crystallization Tc, increase heat ∆Hc, large crystallinity χc...
Abstract Objectives Swimming is one of the most popular forms physical activity. Pool water cleaned with chlorine, which - in combination compounds contained could form chloramines and trichloromethane swimmer’s lungs. The aim present study was to examine effect swimming training an indoor pool on composition swimmers’ respiratory phase metabolomics, develop a system provide basic information about its impact airway mucosa metabolism, help assess risk secondary tract diseases i.e. sport...
Polyoxymethylene (POM) is one of the most popular thermoplastic polymers used in industry. Therefore, interest its potential applications rapid prototyping understandable. Nevertheless, low dimensional stability causes warping 3D prints, limiting applications. This research aimed to evaluate effects POM modification with ethylene-vinyl acetate (EVA) (2.5, 5.0, and 7.5 wt.%) on processing (by melt flow index), structure X-ray microcomputed tomography), properties static tensile tests, surface...
Pulmonary arterial hypertension (PAH) is a rare disease with serious prognosis.
