Dental defects of erosive nature are defined as irreversible losses of dental tissue, caused by long lasting and repeated action of acids that dissolve top layer of hydroxyapatite and fluorideapatites crystal structure, under assumption that aggressive factor is not of bacterial nature.Acids that cause changes on teeth according to their origin are
High-speed rotors on gas foil bearings (GFBs) are applications of increasing interest due to their potential to increase the power-toweight ratio in machines and also formulate oil-free design solutions.The gas lubrication principles render lower (compared to oil) power loss and increase the threshold speed of instability in rotating systems.Howeve
Abstract Background Restless legs syndrome (RLS) is a neurological disorder with a lifetime prevalence of 3-10%.in European studies.However, the diagnosis of RLS in primary care remains low and mistreatment is common.Methods The current article reports on the considerations of RLS diagnosis and management that were made during a European Restless L
The reed straw is assessed as a potential source of widely available renewable biomass for biochar production and compared with two other waste-based biomasses, namely fruit stones blend, and brewery spent grains.The biochars were activated via steam and CO2.While steam activation yielded 12 % carbon from reed biomass, CO2 activation resulted in bi
