    A correlation for predicting the viscosity of Nigerian crude oils
    (Society of Petroleum Engineers, 1990) Amoo, O. A.; Isehunwa, S. O.
    An empirical equation that could be used for predicting the viscosity of Nigerian crudes is presented in this paper. The correlation uses oil specific gravity as the main correlating parameter, and also incorporates the effects of reservoir pressure, temperature and oil formation volume factor. Data from well over 400 samples of Nigerian crudes were used for developing the correlation, with most samples however, from reservoirs at or above saturation pressure. The results show however that the correlation could have general applicability. The correlation when compared with some earlier works proved to be more accurate for Nigerian crudes. Graphical and Statistical error analyses undertaken suggest good performance and accuracy. The correlation should prove valid for estimating the viscosity of Nigerian crudes, as well as other crude types having properties that fall within the range of the data used in this work.

    Haematological and serum biochemical variables in rats treated with ethanol extract of the root of moringa oleifera
    (Biomedical Communications Group, Ibadan, 2014-01) Ola-Davies, O. E.; Olukole, S. G.; Amoo, O. A.
    The haematology and serum biochemical effects of oral administration of the ethanolic extract of the root of Moringa oleifera at 50, 100 and 150 mg/kg were investigated in 30 mated female Wistar rats. The rats were assigned into five groups of six rats each. Group A was given 50mg/kg of the extract; group B, 100mg/kg; group C, 150 mg/kg; group D, 0.2ml of corn oil; and group E, 0.2ml of distilled water. Groups D and E, corn oil and distilled water treatment groups respectively, served as the controls while groups A, B and C were the treatment groups. There was no significant difference (P>0.05) between the two control groups and the treatment groups for the RBC, WBC, PCV, MCV, MCH and MCHC and Hb. However, the mean lymphocyte values for groups B and C were significantly different (P<0.05) from those of group A as well the two control groups. The total protein, albumin, globulin and A/G ratio showed no significant difference (P>0.05) between the two control groups and the treatment groups. There were no significant differences (P>0.05) in the values of AST, ALP, creatinine, urea, GGT, glucose, cholesterol and ALT between the treatment groups and the control groups. It can therefore be concluded that oral administration of ethanolic extract of the root of M. oleifera is harmless to the rats since no adverse effects were detected in haematological and serum biochemical investigations
