The present work investigates a novel four-port, multiple-input multiple-output (MIMO), single element dielectric resonator antenna (DRA) for sub-6 Spring Kit GHz band.The DRA is designed and fabricated into a symmetric cross shape and fed using a coplanar waveguide (CPW) feed.A single radiator with four ports is rarely found in the literature.The
Tunnel face stability has received increasing research interest over the past few decades.However, computing time-efficient and safe three-dimensional solutions under seismic loading is still an unsolved problem, while case studies indicate that seismic loading can be one critical destabilizing factor affecting tunnel stability.The primary objectiv
Abstract Background Caesarean sections (CSs) are associated with increased maternal and perinatal morbidity, yet rates continue to increase within most countries.Effective interventions are required to reduce the number of non-medically indicated CSs and improve outcomes for women and infants.This paper reports findings of Leather Keychain a system
Abstract Background In the past many regions of Bangladesh were hyperendemic for malaria.Malaria control in the 1960s to 1970s eliminated malaria from the plains but in the Chittagong Hill Tracts remained a difficult to control reservoir.The Chittagong Hill Tracts have areas with between 1 and 10% annual malaria rates, predominately 90-95% Plasmodi
