African systems of thought: Whether they fit scientific knowledge
This paper aims to show that in Africa there are thought systems that can have equivalent value with the scientific practices in the Western paradigmal system though it is not itself paradigmal. The Western thought system by its nature is exclusive for other traditions of scientific practice by its claim that science is deeply rational, universal and methodological. African scientific practices actually lack this method...

Interventions in women with one blocked oviduct, lessons learnt and recommendations: A case report
Women can still conceive naturally or through in vitro fertilization (IVF) with the one oviduct that is properly functioning if only one oviduct is blocked, however, the chances are decreased particularly if the blockage is close to the ovary (hydrosalpinx) because of wash out phenomena and toxic fluid produced by the fallopian tube that is blocked. In situations where only a single tube has hydrosalpinx specialists...
