OHMIC HEATING-ASSISTED EXTRACTION OF ANTHOCYANINS FROM BLACK RICE BRAN TO PREPARE A NATURAL FOOD COLOURANT

ABSTRACT Black glutinous rice bran (Oryza sativa L.) is a potential source of the dark purple anthocyanin pigments. This study investigated some quality aspects and bioactive compounds of the colourant powder obtained from rice bran extracted by ohmic heating (OHM) assisted solvent extraction. The moisture content (MC) of the bran sample investigated was adjusted to 30% and 40%. Four different levels of electric field strengths (E) of 50, 100, 150, and 200 V cm– 1 were applied. The results ...

BACTERIOSTATIC NATURE OF ERYTHROMYCIN

ABSTRACT Erythromycin is antibiotics produced from a strain ofStreptomyces erythreus  (later changed to "Saccharopolyspora erythraea") which belongs to the group of macrolides which tends to inhibit the growth/development of bacteria. It sometimes exhibits bactericidal characteristics when administered in high concentration. It carries out its bacteriostatic actions by binding to the 23s RNA component of the 50s ribosome of the bacteria, thereby interfering with the assembly of the 50...

MANAGEMENT OF ZIKA VIRUS

Virus is transmitted by infected mosquitoes that act as vectors to infect individuals during a mosquito bite. The viruses are not reported to be transmitted from person to person, although theoretically this could happen in some rare instances (blood transfusions, organ transplants, sexual contact, and from mother to fetus). Some investigators suggest that transfer of Zika virus may be transmitted by sexual contact more frequently than first suspected, thus providing another way the virus ...

AID OF COMPUTERS

With the outbreak of the computer age in almost all areas of our world, computers had become essential tools in the progress of a nation and aided men throughout the course of history and this very moment, they can be found from a house kitchen to the busy streets of the urban world. Since it can process facts faster and more effective than ever, man has derived many functions from these machines and derived uses from those benefits. One benefit computers give is the help they give through t...

The Use of Computers in Entertainment

In today’s electronic era computers have a hand in almost everything. Entertainment is no exception, in fact with the coming of digital information has made one of its greatest leaps. Movies, games, music, even books that that are simple and easy as it is have been impacted greatly by computers. But how far is too far? Music is now stolen, movies the same, games can be hacked and broken into with simple programs. As technology continues, more and more information will be taken, changed, sto...

Seminar On Cryptography

Abstract "Times New Roman"">  Cryptography is the practice and study of techniques for secure communication and has become so powerful that messages scrambled with it are virtually undecipherable, like many powerful technologies, this is a double -edge sword. In Cryptography,encryption can keep emails, financials transaction and electronic commerce over the internet, secure and private. In this paper, we tried to put the topic of cryptography into context, discussed the main objectiv...

Estimation of Nonorthogonal Problem Using Time Series Dataset

Abstract Based on presentation of the principles of nonorthogonal problem, we discuss the difference of some approaches. A simple procedure to include the R-squared and Root Mean Square Error (R.M.S.E) is proposed and tested. The results showed that the Partial Least Square Regression provides better predictions due to a small R.M.S.E value. Keyword. Nonorthogonal, Mean Square, Partial Least Square, R Square. Table of Content 1.0 Introduction 2.0 The Ordinary Least Square Model 2.3 Ridge Re...

Car expert system

INTRODUCTION Nowadays, it seems like almost every one own a car and in fact, we can say that each house have at least one car. But the more is approximately three cars per house. This figure shows that car is very important to people’s life as it completed the cycle of living. Without a car, it is almost impossible to move from one place to another especially for those who are always mobilise in their jobs. Car simplified our life and it makes time to be more valuable as we can save much ti...

PROBLEMS MILITATING AGAINST TEACHING AND LEARNING OF COMPUTER STUDIES IN JUNIOR SECONDARY SCHOOLS IN NSUKKA LOCAL GOVERNMENT AREA OF ENUGU STATE.

INTRODUCTION The use of the electronic sophisticated and automatic machine called computer has justified the saying of our time that the world is global village. The computer make work done conveniently and faster, Adedapo (2010). Large volumes of data with the aid of  computers are processed automatically into information and distributed across the globe in few seconds.

PREVALENCE OF GASTRO-INTESTINAL HEMINTHIASIS AMONG PRIMARY SCHOOL CHILDREN (IHENGWU VILLAGE, OKO, ORUMBA NORTH L.G.A.)

ABSTRACTGastro Intestinal Helminthiasis was investigated among primary school children in Ihengwu village, Oko between February and March 2015. Sixty samples of freshly collected faeces from sixty randomly selected primary school children between the age of four and ten years from two selected primary schools; Gaius Benton and Pope John primary schools, Oko were analyzed. A small quantity of each faecal sample was collected from the specimen bottle and emulsified on a clean microscopic slide ...

Escherichia coli O157;H7

ABSTRACT Entrohemorrhagic Escherichia coli O157:H7 is a major food borne pathogen causing severe disease in humans worldwide. Healthy cattle are the reservoir of Escherichia coli O157:H7, and bovine food products and fresh produce contaminated with bovine waste are the most common source for disease out breaks in the United States. Escherichia coli O157:H7 also survives well in the environment. The abilities to cause human disease, colonize the bovine gastrointestinal tract, and require tha...
