This letter proposes a novel design for a printed 5G monopole antenna on a vehicle window glass.The proposed antenna consists of a coplanar waveguide (CPW), a monopole radiator, parasitic Natural Kitchen Supplies elements, and a lattice-structure reflector.The parasitic elements are placed on either side of the monopole radiator to improve the bore
Background: Excessive school bag weight is a barrier to active transport to school (ATS).This study examined parents’ and adolescents’ perceptions of school bag weights and actual school bag weights for adolescents in New Zealand.Methods: Parents (n = 331; 76.7% women) completed a survey.Adolescents (n = 682; age 15.1 ± 1.4 years
Traditional concepts of simple liquid spreading may not apply to nanoparticle-fluids.Most investigations pertaining to the wettability alteration of solid surfaces due to the presence of nanoparticles in the fluid are oversimplified, i.e.nanoparticles dispersed in DI-water and smooth, homogeneous, and clean surfaces have been used.From a practical
Self-Compacting Concrete (SCC) that flows by its own weights without compaction or vibration, thereby no external energy from mechanical equipment.In addition to this, cement replacement with silica fume and the introduction of steel fibers have allowed the improvements in durability and hardened properties of SCC.These materials are very important
Weathering of wood--plastic composites (WPCs) leads to discoloration and cracks, which greatly limits their outdoor application.In this study, light stabilizers (including UV-327, HS-944 and nano-SiO2) were added to the shell of a co-extruded high-density polyethylene-based WPC to improve its anti-ultraviolet Cocktail Shakers (UV) ageing properties
