Optimal Slope Designs for Second Degree Kronecker Model Mixture Experiments
(Science publishing group, 2017)
The aim of this paper is to investigate some optimal slope mixture designs in the second degree Kronecker modelbn for mixture experiments. The study is restricted to weighted centroid designs, with the second degree ...
Differential Geometry: An Introduction to the Theory of Curves
(Science publishing group, 2017)
Differential geometry is a discipline of mathematics that uses the techniques of calculus and linear algebra to study problems in geometry. The theory of plane, curves and surfaces in the Euclidean space formed the basis ...
Technological Preferences, Levels of Utilization and Attitude of Students Towards Mobile Learning Technologies in Chartered Universities, Kenya
(Australian International Academic Centre, 2017-10)
The affordances of mobile technologies are being felt in many sectors of world’s economy including university education. By solving the limitations of fixed instructional technologies, mobile technologies have received ...
Hydromagnetic Turbulent Flow Between Two Parallel Infinite Plates
(Science Journal of Applied Mathematics and Statistics, 2017)
In this study we shall investigate hydromagnetic turbulent unsteady flow of an incompressible electrically conducting fluid between two parallel infinite plates. The flow variables such as velocity and thermodynamic ...
Evaluation of In vivo Toxicity of Methanolic Leaf Extract of Vernonia lasiopus (O. Hoffman)
(Journal of Pharmacognosy & Natural Products, 2017)
The main objective of this study was to evaluate the in vivo toxicity of methanolic leaf extract of Vernonia lasiopus. To provide information on the safety of V. lasiopus, we evaluated its acute and sub-chronic toxicity ...
An Introduction to Differential Geometry: The Theory of Surfaces
(Science Publishing Group, 2017)
From a mathematical perspective, a surface is a generalization of a plane which does not necessarily require being flat, that is, the curvature is not necessarily zero. Often, a surface is defined by equations that are ...
The economics and gender factor in soya bean production and profitability in Kenya: a case of smallholder farms in Western Kenya
(Int. J. Agricultural Resources, Governance and Ecology, 2017)
Soya-bean is among world’s major crops, cultivated for its high oil, proteins content and its ability in soil-fertility amendments. The study assessed the determinants, constraints and profitability/gross-margins of soya-bean ...
ON THE MAXIMAL NUMERICAL RANGEOF ELEMENTARY OPERATORS
(2017)
The notion of the numerical range has been generalized in different directions. One such direction, is the maximal numerical range introduced by Stampfli (1970) to derive an identity for the norm of a derivation on L(H).Unlike ...
