Antimicrobial screening , nutrients profile and Pyhtochemical analysis of the leaf extracts of Tetrapluera tetraptera

ABSTRACT Phytochemical and Antimicrobial activity of the leaves of Tetrapluera tetraptera using aqueous and ethanolic extract was studied. The leave was observed to be highly rich in polyphenols, flavonoid, reducing compounds and alkaloids. Glycosides, saponins and tanins were present in small amount, there was absence of Phlobotanins, anthraquinones and hydroxyl methyl anthraquinones. In order to confirm the exact concentration of the Phytochemicals present in the leave of T. tetraptera, a ...

Design and construction of an automatic Battery charger

                                                         ABSTRACT This project describes the design and construction of an automatic Battery charger. Automatic Battery chargers are not particularly cheap, but the protection they afford in protecting batteries against overcharging and possible battery damage is highly desirable. However the work carried out through the construction and design of an inexpensive alternative to the commercially available fully Automat...

In Vitro Evaluation of Metal Chelating and Ferric Reducing Potentials of Methanol Extracts of Adasonia digitata Leaf

ABSTRACT Adansonia digitata L. (Malvaceae) is commonly known as baobab tree native to Africa. Baobab is a multi-purpose tree which offers protection and provides food, clothing and medicine as well as raw material for many useful items. This study aims to elucidate the metal chelating and ferric reducing potentials of methanol extracts of Adansonia digitata L. (Malvaceae) leaf using in vitro model. Phytochemical screening was carried out on the extract and it showed that the extract contains...

Physicochemicls and microbial quality of local fermented milk

ABSTRACT Culturally, consumption of local fermented skimmed milk (nono/tsala) is common in Northern Nigeria and many other parts of Africa and it is sometimes associated with microbial diseases due to poor hygienic practice. Hence, this study was conducted with the objectives of assessing the microbial quality and some physicochemical parameters, a purposive sampling was used to collect a total of 12 different samples from Dutse local government, Jigawa state. The results obtained showed that...

DESIGN AND IMPLEMENTATION OF CAR REGSTRATION LICENSE PLATE DETECTION AND RECOGNITION SYSTEM

ABSTRACT Public vehicle traffic management is becoming harder, as the number of the vehicles on Nigerian roads is increasing. The Federal Road Safety Corps and other law enforcement agencies face real problems dealing with the different kinds of traffic violation, which introduces the need for an automated way to help identifying and controlling these violations.  The Online vehicle recognition system, plays an important role in addressing these issues as its application ranges from parking...

EFFECT OF PROCESSING METHOD ON THE FUNCTIONAL PROPERTIES OF CASSAVA FLOURS

ABSTRACT The effects of variety and processing methods on the functional properties of cassava flours were studied. The functional properties of the flour were determined using standard procedures. Cassava roots were fermented, blanched, soaked, dried and milled into flour. The functional properties of the flour were determined. There were variety and method of processing influence of the functional properties significantly. The gelation capacities varied between 75% and 80% bulk density, emu...

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

ABSTRACT The 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 agency tha...

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.

Antibacterial activity of leaf extract of phyllantgus amarus agaice salmonella species coursitive agent of typhoid fever

ABSTRACT The study was conducted to assess the antibacterial activity of Phyllanthus amarus (Schum and Thonn) extract against Salmonella typhi causative agent of typhoid fever at the laboratories of the Departments of Chemistry and Theoretical and Applied Biology of the College of Science, Kwame Nkrumah University of Science and Technology, Kumasi. The objectives were to determine the highest yield of crude extract of P. amarus using different proportions of water to ethanol and to determine ...

STUDENTS’ PERCEPTION OF UTME AND UNILORIN COMPUTER BASE TEST (CBT)

The automatic means of assessment has proven to be the best solution to the process of selecting qualified prospective candidates among the growing population of candidates seeking admission into tertiary institutions and also evaluation of large population of students in the higher institutions in Nigeria. CBT (computer-based testing) is the automatic evaluation or assessment by which knowledge of students or candidates are measured or tested. It is in this regard that the Joint Admission a...

LOGISTIC REGRESSION ON EFFECT OF TUBERCULOSIS AND MALARIA ON HIV

Logistic regression model deals with the relationship that exists between a dependent variable and one or more independent variables. It provides a method for modeling a binary response variable, which takes values 1 and 0. Further, Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables. It is similar to a linear regression model but is suited to models where th...

Hamiltonian Approach for Constrained Optimization

The Hamiltonian approach for constrained optimization is indeed a useful tool in the hands of the economists, scientists and statisticians who applied it in the modelling of optimization problems. It can be noted that the treatise in this research work is an eye opener for a better understanding, application and utilization of the method as we exploit its vitality to solving optimization problems. Though, the approach seems to be a derived approach from existed ones but also intensified a g...

Analysis of Self-Organizing Map Algorithm

Artificial Neural Networks have proven to be very useful in areas that concern data mining. This research project borders on the use of kohenen self-Organising Map, a neural network based unsupervised, competitive learning algorithm that can seperate a given dataset of customers and their prefences into groups known as clusters.
