    Leaving no one behind
    (University of Namibia, 2015) Kazembe, Lawrence N.; Archibong, Edet F.
    The African continent continues to be faced with myriad of challenges, particularly in the public health sector. A few figures exemplify the magnitude of the problem. Infant and maternal mortality remains stubbornly high, compared to other regions of the world. According to the Inter-agency Group for Child Mortality Estimation [1-2], the risk of a child dying before completing the first year of age was highest in the WHO African Region (55 per 1000 live births), over five times higher than that in the WHO European Region (10 per 1000 live births). Similarly, every day about 800 women die due to complications of pregnancy and child birth. Of the 800 daily maternal deaths, 500 occur in sub-Saharan Africa and 190 in Southern Asia, compared to 6 in developed countries. The risk of a woman in a developing country dying from a maternal-related cause during her lifetime is about 23 times higher compared to a woman living in a developed country

    On the electronic structure
    (University of Namibia, 2013) Archibong, Edet F.
    The ground and low-lying excited states of AlS2 and AlS􀀀2 have been studied using density functional theory (DFT) and coupled cluster [CCSD(T)] approximations, in conjunctions with the 6-311+G(2df) one particle basis set. AlS2 is linear with a 2Õg ground state. CCSD(T) predicts that the 2A2 state of the C2v isomer is separated from the ground state by less than 0.1 eV, while the 2Õu and 2å+ u states in D¥h symmetry are located at 0.67 eV and 1.40 eV, respectively, above the 2Õg state. The AlS􀀀2 anion possesses a 1å+ g ground state with a very similar geometry with the neutral molecule. At the CCSD(T) level, adiabatic electron detachment energies for the [AlS2(2Õg) AlS􀀀2 (1å+ g )] transition is 4.03 eV.

    Science: An all encompassing field
    (University of Namibia, 2013) Kazembe, Lawrence N.; Archibong, Edet F.; Chimwamurombe, Percy M.; Singh, Shyam; Chinsembu, Kazhila C.
    What unites science, as Sir David Cox mentioned, is not the subject matter we all work in, but the methodology and the thought process that help solve the problems that arise [1]. Put differently, it is the replicability of its methods, the validity of its findings and reliability of its instruments and techniques. The diversity in science now emphasizes that not a single subject matter will work alone in isolation - especially if you are working in applied sciences, but has to learn from others. Even so, contemporary applied sciences have extended this collaboration to the social sciences [2]. For instance, in implementation science they have learnt to involve social sciences to inform human behaviour if scaling-up of interventions is to be a success.
