1. ETHANOL PRODUCTION FROM YAM (DISCOREA SPP) PEELS

​​​​​​Background of the study: Yams (Discorea spp) of the family Diocoreaceae are members of the flowering plant. They are monocots, related to palms, grasses and archids. Most yam species grow in the tropics and subtropics area with fairly heavy total annual rainfall, but with a definite day season. During the rainy season, they produced one or more underground tubers to store food and water through the dry season the tubers are thickened stems. Most yam plant have smal...

3. A STUDY OF SALIVA AND CHEEK CELLS DNA EXTRACTION WITH THE USE OF HOUSEHOLD CHEMICALS

ABSTRACT: This study was carry out to examine saliva and cheek cells DNA extraction with the use of household chemicals. This study adopts the experimental research design where data collected are tested. Quantitative assessment was performed by measuring optical density at 260/280 ratio using Nanodrop (IMPLEN NanoPhotometer®, Germany). Qualitative assessment was performed by gel electrophoresis at 0.7% agarose gel. Then 1 µL sample was mixed w...

4. DESIGN AND CONSTRUCTION OF A METRE BRIDGE

BACKGROUND HISTORY OF WHEATSTONE BRIDGE: The study of electricity is an important aspect of physics because electricity plays a key role in the modern world.  The working of most modern appliances such as radio, television, computers and calculators, refrigerator, air conditioners, sound systems and electric fan is possible as a result of electricity.

There are three basic quantities, which must be clearly understood before we can proceed with...

5. DETERMINING THE EFFECT OF PARTICLE SIZE DISTRIBUTION ON SHEAR BEHAVIOR OF SOIL

1.1 Background to the Study

Soil behavior is a fundamental factor in geotechnical engineering, influencing the design and stability of infrastructure, including buildings, roads, and dams. Among the soil properties critical to engineering applications, shear strength is paramount as it determines a soil's resistance to deformation and failure under stress. Shear strength is profoundly affected by particle size distribution (PSD)...
