The antisickling effects of the extracts of three vegetables highly consumed in Nigeria were investigated which included: Allium cepa (Onion), Allium sativum (Garlic) and Telferia occidentalis (Ugu). The extracts were partitioned into, the fat-soluble (FAS), the water-soluble (WAS), the butanol-soluble (BUS) and the crude aqueous extracts (CAEs) respectively. Free amino acid concentrations of t...

Fountains (negatively buoyant jets) are commonly used in numerous engineering applications, such as the natural ventilation buildings and smoke spread compartment fires. In this study, long-term behavior of weak round fountains homogeneous ambient confined a cylindrical container was analyzed using three-dimensional direct numerical simulation over range Froude number ( Fr ), Reynolds (Re), dim...

Introduction: The restoration of old fountains is essential to the cultural life society since it preserves architectural spirit past and conveys historical heritage present day. Besides, create a favorable atmosphere in summer, humidifying air. In course study, we developed an approach engineering systems technology operation fountain St. Petersburg. Methods: We performed detailed survey cast-...

Aims. Nonlinear behaviour of galactic dynamos is studied, allowing for magnetic helicity removal by the galactic fountain flow. Methods. A suitable advection speed is estimated, and a one-dimensional mean-field dynamo model with dynamic α-effect is explored. Results. It is shown that the galactic fountain flow is efficient in removing magnetic helicity from galactic discs. This alleviates the c...
