Biometric control systems

Checking students for examination and attendance in a university environment is too cumbersome as a result of the increasing number of students. Private institutions especially are faced with problems of attaining accurate records of students’ attendance which normally involves circulating papers for students to sign in and sign out by registering their names on paper during examinations and this has proved to be stressful, time consuming, unreliable, inaccurate and inefficient. The study ...

DATA FEDERATION OF PUBLIC DATABASE OF NIGERIANS USING DATABASE LINKS AND WEB SERVICES

ABSTRACTThe project is the design and implementation of database federation of public database of Nigerians using database links and web services. It involves the design of a representative of the primary database that houses comprehensive information about Nigeria residences; other smaller databases representing some of the government agencies concerned with the issuance of different types of identification cards/documents and a website for a representative of government security agen...

Review on Phosphate Solubilizing Fungi

Phosphorus (P) is the second important nutrient after nitrogen. In plants, phosphorous increases the strength of cereal straw, promotes flower formation and fruit production, stimulates root development and essential for seed formation. Mobility of phosphate ions in the soil is very low due to their high retention in soil. In this regard, P supply through biological systems is considered a viable alternative, and inoculation of Phosphate solubilizing microorganisms, especially fungi to soil, ...

Review on Microbiological Instruments

The most fundamental skill of microbiology is the use of the microscope. This earliest microscope magnified objects up to 100 times the objects actual size. Today’s 13 microscopes often employ more than two sets. The largest and most accurate microscope is the electron microscope that uses electrons in a focused beam to illuminate objects rather than light. The electrons pass through the specimen being viewed and are electrically focused. The teaching of such an important subject ...

Review on Metal Resistance and Its Association with Antibiotic Resistance in Microbes

Antibiotic resistance is recognized as a major global threat to public health by the World Health Organization. The major driver for the development of antibiotic resistance is considered to be the use, misuse and overuse of antibiotics in humans and animals. Non-antibiotic compounds, such as antibacterial biocides and metals, may also contribute to the promotion of antibiotic resistance through co-selection. This may occur when resistance genes to both antibiotics and metals/biocides are co-...

Review on HIV Virus

Human immunodeficiency virus (HIV) and its subtypes are retroviruses and the etiologic agents of AIDS. Human retroviruses were unknown until the 1980's. HIV belongs to a large family of ribonucleic acid (RNA) lentiviruses.[21] These viruses are characterized by association with diseases of immunosuppression or central nervous system involvement and with long incubation periods following infection before manifestations of illness become apparent. Retroviruses are broadly classified into three ...

Review on Microbial Production of Organic Acid

The first individual process for citric acid production was the liquid surface culture (LSC), which was introduced in 1919 by Société des Produits Organiques in Belgium, and in 1923 by Chas Pfizer & Co. in US. After that, other methods of fermentation, such as submerged fermentation were developed. Although this technique is more sophisticated, surface method required less effort in operation and installation and energy cost. Organic acids such as citric, malic and pyruvic are used e...

Review on Hepatitis E Virus and Related Viruses in Wild, Domestic and Zoo Animals

Hepatitis E is a human disease mainly characterized by acute liver illness, which is caused by infection with the hepatitis E virus (HEV). Large hepatitis E outbreaks have been described in developing countries; however, the disease is also increasingly recognized in industrialized countries. Mortality rates up to 25% have been described for pregnant women during outbreaks in developing countries. In addition, chronic disease courses could be observed in immunocompromised transplant pat...

Review on Biodegradation of Organic Compounds and Plastics

Biodegradation is defined as the biologically catalyzed reduction in complexity of chemical compounds. Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms. When biodegradation is complete, the process is called "mineralization". However, in most cases the term biodegradation is generally used to describe almost any biologically mediated change in a substrate. So, understanding the process of biodegradati...

Review on Microbial Ecology of Fermented Foods and Beverages

Fermented foods and beverages play a significant role in most societies and major contribution in fulfil the protein requirements of large population. There is a relation between microbial diversity of food products and health benefits. Yoghurt is a fermented dairy product, having several health benefits. Yoghurt starter culture consists of a blend of Streptococcus thermophilus and Lactobacillus delbrueckii subsp Bulgaricus. Yoghurt is mainly of two types i.e. set yoghurt and stirred y...

THE POTENTIALS OF SNAILSHELL AS A REINFORCEMENT FOR DISCARDED ALUMINIUM BASED MATERIALS.

               ABSTRACT Snail  shells  and  discarded  aluminium  components  are  of  low  economic  values,  and are  often  considered  as  environmental  pollutants.  Finding  ways  of  utilizing  these  supposed wastes  is  consequently  a  direct  way  of  creating  wealth  from  wastes.  Snail  shell  particles  are known  for  their  hardness,  and  thus  considered  as  good  alloying  agent  for  aluminum  based composites.  ...

Serum Liver Enzymes Profile and Antioxidant Status of Male Wistar Rats Following Feeding with Cocos Nucifera

The work was aimed at investigating the effect of Cocus nucifera on male albino rats. A number of rats were placed in groups and all groups were fed Cocus nucifera except one group, the control group. Analysis of results was done with ANOVA.

Barriers to the Successful Integration of ICT in Teaching and Learning Environments: A Review of the Literature

The use of ICT in the classroom is very important for providing opportunities for students to learn to operate in an information age. Studying the obstacles to the use of ICT in education may assist educators to overcome these barriers and become successful technology adopters in the future. This paper provides a meta-analysis of the relevant literature that aims to present the perceived barriers to technology integration in science education. The findings indicate that teachers had a strong ...
