The product will be characterized in terms of their crystalline structure (Powder X-Ray Diffraction)‚ microstructural behavior (Scanning electron microscopy)‚ Dielectric property (Permittivity analyzer) and crystal lattice vibration (Fourier-Transform Infrared Spectroscopy). In the X-Ray diffraction spectra‚ it is expected to observe the presence of a doublet peak from the reflection of (002)

The winged bean (Psophocarpus tetragonolobus) is a twining‚ perennial herbaceous legume which can climb to 3-4 meters (Kantha and Erdman‚ 1985). As a leguminous plant‚ winged bean can be used in almost all parts of the plant. Fruit‚ leaves‚ flowers‚ bulbs and seed are edible and contain high protein and oil (Kotaru et al.‚ 1987; Dwiani et al.‚ 2014). The mature‚ dry seed is the most nutritious part of the winged bean. Their outstanding nutritive quality is based‚ above all‚ on their high protein

The term biology is derived from the Greek word βίος‚ bios‚ "life" and the suffix -λογία‚ -logia‚ "study of."[4] The Latin form of the term first appeared in 1736 when Linnaeus (Carl von Linné) used biologi in his Bibliotheca botanica. It was used again in 1766 in a work entitled Philosophiae naturalis sive physicae: tomus III‚ continens geologian‚ biologian‚ phytologian generalis‚ by Michael Christoph Hanov‚ a disciple of Christian Wolff. The first German use‚ Biologie‚ was used in a 1771 translation

Liposomes of specific composition were prepared using a standard protocol. Briefly‚ Overnight hydration of lipid thin film obtained by high pressure vacuum evaporation of lipid mixture was done using Buffer A (Hepes-10 mM‚ KCL-150 mM‚ and 2mM EDTA‚ pH 7.4). This was followed by short periods of shaking and bath sonication for better retrieval of the lipids. Vesicles were generated from this initial mixture by freeze-thawing (10 cycles) and bath sonication for 20 min. 100 nm liposomes were produced

CHAPTER ONE INTRODUCTION The industrial attachment is an important part of the course structure of the university. This is the time students appreciate the theoretical work done in the lecture halls when seen practically. This attachment introduces the student to the outside world in terms of working experience and also prepares them for the future. The department of applied biology therefore introduced the industrial attachment program in its learning curriculum to give students a chance to combine

Without heat- fixing we dry the slide and observed under microscope observing the morphology of rod shapes which eliminated any
