processed to obtain 5.36% ± 0.355% v/w bioethanol using Aspergilus niger for hydrolysis and Saccharomyces cerevisiae for fermentation. J. curcas seeds were collected from contracted farmers of Energy Africa in Shimba hills, Coast region. Oil from the seeds was machine cold pressed and solvent ex-tracted using n-hexane giving 44% - 53%v/w yield.
In this paper, a CAD-based trajectory planning scheme for parallel machining robots is introduced using the parametric Non-uniform rational basis spline (NURBS) curves. First, a trajectory is designed via a NURBS curve then, a motion scheduling architecture consisting of time-dependent and constant feedrate profiles is advised to generate the position commands …

The motion of objects is determined by the relative size and the direction of the forces that act upon it. Free-body diagrams showing these forces, their direction, and their relative magnitude are often used to depict such information. In this Lesson, The Physics Classroom discusses the details of constructing free-body diagrams. Several examples are discussed.
However, these kinematic indicators may be ambiguous in providing a unique kinematic solution because MTCs exhibit complex flow patterns (Omeru …
