Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
(International Journal of Science and Research, 2015)Increasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing of alternative ways of beneficiating the iron ore. This paper reports on the study that was done ... -
Beneficiation of Iron in Thermal-Reduced Ilmenite by Magnetic Separation
(2013)Increasing demands for Iron in countries development, and lack of conventional reducing agents has resulted into sourcing of alternative ways of beneficiating the iron ore. This paper reports on the study that was done to ... -
Bioactive carbazole alkaloids from Alysicarpus ovalifolius (Schumach)
(CrossMark, 2015)Phytochemical and biological evaluation of the stem bark of Alysicarpus ovalifolius led to the isolation of three carbazole alkaloids identified as mohanimbine (1), koenimbine (2) and koenidine (3) along with quercetin ... -
Bioactive Constituents of Conyza floribunda
(Medwell Journals, 2010)The study describes the antibacterial and antifungal effects of both CH2Cl2 and MeOH crude extracts, collected fractions and pure isolates of Conzya floribunda. The antimicrobial activity tests were carried out using agar ... -
Biopesticidal Extractives and Compounds from Warburgia Ugandensis against Maize Weevil (Sitophilus zeamais)
(Bentham Science Publishers, 2015)Agricultural production is constrained by insect pests, which cause serious post-harvest losses of up to 43% in developing countries. Maize weevil (Sitophilus zeamais Motschulsky.) is one of the most destructive pests of ... -
The black-Scholes formula and the Greek parameters for a nonlinear Black-Scholes equation
(2016)We study the Greek (risk) parameters of a nonlinear Black-Scholes partial differential equation whose nonlinearity is as a result of transaction costs. These parameters are derived from the Black-Scholes formula of the ... -
Blood Pressure and Arterial Stiffness in Kenyan Adolescents With a+Thalassemia
(2017-03)Background-—Recent studies have discovered that a-globin is expressed in blood vessel walls where it plays a role in regulating vascular tone. We tested the hypothesis that blood pressure (BP) might differ between normal ... -
Blood Pressure and Arterial Stiffness in Kenyan Adolescents With the Sickle Cell Trait
(2017-05-22)The potential association between sickle cell trait (SCT) and increased arterial stiffness/blood pressure (BP) has not been evaluated in detail despite its association with stroke, sudden death, and renal disease. We ... -
