DESIGN OF DIRECT CURRENT MOTOR SPEED CONTROL USING PULSE WIDTH MODULATION (PWM) TECHNIQUE ABSTRACT Next to stepper motors, the Permanent Magnet DC Motor (PMDC) is the most commonly used type of small direct current motor available producing a continuous rotational speed that can be easily controlled. Small DC motors ideal …

COMPARATIVE ANALYSIS OF VITAMIN C. CONTENT (ASCORBIC ACID) IN PINEAPPLE AND BANANA Abstract: Vitamin C, also known as ascorbic acid, is a water soluble vitamin that is regarded as one of the safest and most effective nutrients. Vitamin C can be found in most fruits and vegetable. The objective of …

MICROORGANISMS ASSOCIATED WITH THE SPOILAGE OF POST-HARVEST SWEET POTATOES (IPOMOEA BATATAS) Abstract :  In the tropics, research on postharvest aspects of sweet potato has been limited especially in the field of microbiology. Several microorganisms (mostly fungi) have been found to induce spoilage in stored sweet potato. The most important among them …

RECYCLING OF SPENT ENGINE-OIL ABSTRACT Engine oils are made from crude oil and its derivatives by mixing of certain other chemicals (additives) for improving their certain properties. Lubricating oil is used to lubricate moving parts of engine, reducing friction, protecting against wear, and removing contaminants from the engine, act as …

EFFECT OF ARMATURE REACTION ON DC MOTOR DRIVE ABSTRACT Similar to DC generator, armature reaction happens in a DC motor. This is often anticipated as a result of once current drifts through the armature conductors of a DC motor, it creates armature flux which on the flux created by the main …

CONSTRUCTION OF A PROGRAMMABLE CENTRIFUGE ABSTRACT In 1986, the company Sumy Machine-Building Shops was created from funds held by Sumy sugar-plant owners, who had attracted Belgian capital and technology for the fabrication and repair of equipment for sugar plants. Today, the company Sumskoe NPO im. M. V. Frunze is one …

CORROSION CONTROL IN OIL PIPELINE USING CATHODIC PROTECTION ABSTRACT Galvanic cathodic protection involves protecting a metal surface of a piece of equipment using another metal that is more reactive. The latter metal, usually called the galvanic or sacrificial anode, has a less negative electrochemical potential compared to the metal component …

FUZZY LOGIC SYSTEM IN POWER SYSTEM USING WATER LEVEL CONTROLLER MIMO COMPUTER SYSTEM AND OVERVIEW ABSTRACT Water level control is highly important in industrial applications such as boilers in nuclear power plants. In this work a simple water level indicator and a water level controller based on fuzzy logic is …

ISOLATION AND CHARACTERIZATION OF MICROORGANISMS IN WASTE OIL CONTAMINATED SOIL FROM NEKEDE MECHANIC VILLAGE ABSTRACT A study was conducted in order to decipher the microorganisms from oil contaminated sites for oil degradation abilities. Four used oil degrading Bacterial samples were isolated from oil contaminated sites in Lucknow. One isolate MJH1101 …
