We present results from ab-initio, self-consistent density functional theory calculations of electronic and related properties of zinc blende boron phosphide (zb-BP). We employed a local density approximation potential and implemented the linear combination of atomic orbitals formalism. This technique follows the Bagayoko, Zhao, and Williams method, as enhanced by the work of Ekuma and Franklin. The results include electronic energy bands, densities of states, and effective masses. The calculated band gap of 2.02 eV, for the room temperature lattice constant of a = 4.5383 Å, is in excellent agreement with the experimental value of 2.02 ± 0.05 eV. Our result for the bulk modulus, 155.7 GPa, agrees with experiment (152-155 GPa). Our predictions for the equilibrium lattice constant and the corresponding band gap, for very low temperatures, are 4.5269 A and 2.01 eV, respectively. [ABSTRACT FROM AUTHOR]

B Background: b Lassa fever (LF) is endemic in Nigeria. HCWs 123 (100.0%) believed Lassa fever is preventable by IPC practice while 14 (11.4%) and 11 (8.9%) believe infection cannot occur in the lab and through contact with infected body secretions respectively. Outbreaks usually begin in communities however, substandard Infection Prevention and Control (IPC) practices can cause secondary infection in Health Care Workers (HCW). [Extracted from the article]

B Background: b Hepatitis B virus (HBV) infection is ranked among the top ten killers by the World Health Organisation. Though vaccine preventable, medical students are outside the age group which benefits from the introduction of HBV vaccine into the National immunization schedule and are a high risk group for HBV infection. We studied the HBV vaccination status of medical students who commenced clinical training to determine their risk of infection. [Extracted from the article]
