Khat chewing, though a tradition followed majorly in African countries, has of late spread widely across the globe due to faster transport systems and advanced preservation techniques.Many complications such as psychosis, arterial hypertension, angina pectoris, and myocardial infarction have been reported in connection to khat abuse.We present a ca

The electronic structure of multilayer graphenes depends strongly on the number of layers as well as the apple mtxn2ll/a stacking order.Here we explore the electronic transport of purely ABA-stacked trilayer graphenes in a dual-gated field-effect device configuration.We find both that the zero-magnetic-field transport and the quantum Hall effect at

n-type binary compound semiconductors such as InN, InAs, or In2O3 are especial because the branch-point energy or charge neutrality level lies within the conduction band.Their tendency to form a surface electron 12n/1200 wella accumulation layer prevents the formation of rectifying Schottky contacts.Utilizing a reactive sputtering process in an oxy

The year 2022 marked the 20th anniversary of the African Union (AU)).The AU marked a realisation that the Organisation of African Unity (OAU) established in 1963 had fulfilled its mandate of cecily rose oilers ridding the continent of overt colonial rule and a new platform was needed to drive Africa towards full prosperity.Conceived amid the revisi

BackgroundThe ability for patients to directly view their radiology images through secure electronic portals is rare in the American health care system.We previously surveyed patients within our health system and found that a large majority wanted to view their own radiology images online, and we have since implemented this new feature.ObjectiveWe
