MICROBIOLOGICAL AND MICROBIAL ASSESSMENT OF COMMERCIALLY PREPARED YOGHURTS SOLD IN ENUGU

Yoghurt is a cultural diary product produced by lactic fermentation of milk (Hui, 1992). Yoghurt is produced by the controlled fermentation of milk by two species of bacteria; Lactobacillus bulgaricus and Strptococcus thermophilus. These two species of bacteriae have now been established as the yoghurt starters. Any sort of milk may be used to make yoghurt, but modern production is dominated by cow milk. It is the fermentation of the milk sugar (Lactose) into lactic acid that gives yoghurt ...

Assessment of Newcastle Disease Virus Antibodies Among Poultry Birds (A Case Study of Anyigba Kogi State)

ABSTRACT Newcastle disease (ND) is one of the most important avian viral diseases because of its high economic impact on the poultry industry.  Newcastle disease is now claimed to be responsible for 70-80% of annual death in village chickens. Losses in hundreds of poultry birds of various ages and sexes in Anyigba Kogi State of Nigeria is attributed to the disease. The prevalence is always at its peak during the dry season (Harmattan) of every year in the last decade. The result of this stud...

Production of Amylase from Isolated micrococcus from Fermented Ugba

ABSTRACT Ugba (Ukpaka) is the Ibo name of the fermented African Oilbean seeds (Pentaclethra macrophylla, Benth). It is a popular traditional food condiment in Nigeria especially among Ibo ethnic group generally. It is produced by natural (local) fermentation in homes as a small family business. It is an important and cheap source of protein for people whose staple foods are deficient in proteins. It is also eaten as a delicacy and used as flavouring for soup. This write up aims to describe t...

PRODUCTION AND QUALITY EVALUATION OF BANANA (MUSA SAPIENTUM) WINE

ABSTRACT  Juice was extracted from banana (Musa sapientum) pulp with the addition of lemon juice and was inoculated with Baker’s yeast (Saccharomyces cerevisiae) and held at 30  for seven days. The result of the yeast count increases at 48hr, and at 96hr the yeast count decreased gradually. It ranges from 4.9x107 cfu/ml at 0hr, 5.1x107 at the 48hr and 4.8x107 cfu/ml at 168hr. The pH of the Banana wine produced at the end of fermentation decreased (2.85) while the titrable acidity of ...

MICROBIAL PROFILE OF SUYA MEAT IN ENUGU STATE

ABSTRACT Twenty (20) samples of suya meat in Enugu were collected randomly and analyzed microbiologically and the isolates were identified as Staphylococcus aureu (35%), Escherichia coli (15%), Streptococcus species (15%), Pseudomonas (35%). The most frequently isolated organisms were Staphylococcus and Pseudomonas. The total viable bacterial counts ranged from 1.9x  3.8x  cfu/g whereas, total coliform count ranged from 1.1x -3.0x  cfu/g on Nutrient agar and MacConkey agar  respectively. ...

BIOMETRICS AUTHENTICATION SYSTEM

ABSTRACT "Biometrics" means "life measurement" but the term is usually associated with the use of unique physiological characteristics to identify an individual. The application which most people associate with biometrics is security. However, biometrics identification has eventually a much broader relevance as computer interface becomes more natural. Knowing the person with whom you are conversing is an important part of human interaction and one expects computers of the future to have the s...

APARTMENT MANAGEMENT SYSTEM

ABSTRACT In the higher institution, it is the duty of the management to provide the students with conducive environment for learning. In a country like Nigeria, the number of students in higher institutions is quite massive. In a situation like this, the management of the some of these higher institutions may be tempted to admit more students than can manage. This may put the welfare of the students of risk. Over the years, the students’ welfare/affairs departments of most schools in N...

CHARACTERISTICS OF JAVA

ABSTRACT A high-level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web.  Java is an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors. Java source code files (files with a .java extension) are...

COMBATING DATA INPUT ERRORS IN PROGRAMMING

ABSTRACT Debugging is a necessary process in almost any new software or hardware development process, whether a commercial product or an enterprise or personal application program. For complex products, debugging is done as the result of the unit test for the smallest unit of a system, again at component test when parts are brought together, again at system test when the product is used with other existing products, and again during customer beta test, when users try the product out in a real...

COMPOUND INTEREST CALCULATION SYSTEM IN RETAIL BANK

ABSTRACT Interest is a fee paid by a borrower of assets to the owner as a form of compensation for the use of the assets. It is most commonly the price paid for the use of borrowed money, or money earned by deposited funds.  When money is borrowed, interest is typically paid to the lender as a percentage of the principal, the amount owed to the lender. The percentage of the principal that is paid as a fee over a certain period of time (typically one month or year) is called the interest rate...

COMPUTER FORENSICS

ABSTRACT This paper will discuss the need for computer forensics to be practiced in an effective and legal way, outline basic technical issues, and point to references for further reading. It promotes the idea that the competent practice of computer forensics and awareness of applicable laws is essential for today’s networked organizations. This subject is important for managers who need to understand how computer forensics fits as a strategic element in overall organizational computer...

COMPUTING FOR THE HANDICAPPED

ABSTRACT The United Nations has designated 1981 the International Year for Disabled Persons. It is therefore appropriate that Computer is dedicating its first issue of the year to computing and the handicapped. The evolution of low cost computing technology promises an unprecedented spectrum of opportunities for the developmentally disabled. From aids to independent living to flexible tools that can greatly increase the variety and quality of job opportunities, the rapidly evolving field of c...

USING CRYPTOGRAPHY IN INFORMATION TECHNOLOGY

ABSTRACT Cryptography is an emerging technology in which two parties can secure network communications by applying the phenomena of quantum physics. The security of these transmissions is based on the inviolability of the laws of quantum mechanics. Quantum cryptography was born in the early seventies when Steven Wiesner wrote "Conjugate Coding", which took more than ten years to end this paper. The quantum cryptography relies on two important elements of quantum mechanics - the Heisenberg Unc...

DESIGN OF POWER SYSTEM STABILIZER USING FUZZY LOGIC

ABSTRACT Power system stabilizers (PSS) must be capable of providing appropriate stabilization signals over a broad range of operating conditions and disturbance. Traditional PSS rely on robust linear design method in an attempt to cover a wider range of operating condition. Expert or rule-based controllers have also been proposed. Recently fuzzy logic (FL) as a novel robust control design method has shown promising results. The emphasis in fuzzy control design center is around uncertainties...

BACTERIAL CONTAMINANTS ASSOCIATED WITH COMMERCIAL POULTRY FEED FROM THREE DIFFERENT COMPANIES

ABSTRACT The bacterial contaminants associated with commercial poultry feeds from three companies in Nigeria (vital, Guinea and Top) were studied using streak plate techniques.  The culture media used were Nutrient agar and Mac Cokey agar.  The aim/ objective of the study is: To ascertain the microbial safety of commercial poultry feeds produced by companies.  To isolate microorgaisms that are contaminants of poultry feeds, to identify the bacterial types and to determine the microbial lo...
