NETWORK BASED SECURITY INFORMATION SYSTEM

CHAPTER ONEINTRODUCTION1.1    IntroductionSecurity on the Internet and on Local Area Networks is now at the forefront of computer network related issues.  The  evolution  of  networking  and  the  Internet,  the  threats   to   information   and   networks   have   risen   dramatically.   Many   of   these   threats   have   become   cleverly    exercised    attacks    causing    damage    or    committing   theft.   The   Internet   ...

Design and implementation of a Simple word processor

CHAPTER ONEINTRODUCTION1.1 BACKGROUND OF THE STUDY The importance of computer cannot be over emphasized with respect to designing and implementation in text editing package which could be in sciences, engineering, business or government etc.  Consequently, computers are becoming indispensable. This is obviously true in developed countries; like Nigeria is gradually being gravitated into computer oriented society with professional engineers, analyst, design and implementation of...

Physicochemical and rheological characterization of pectin-rich fraction from blueberry (Vaccinium ashei) wine pomace

Blueberry wine pomace is rich in pectin, which has been extensively used as a functional dietary fiber and a rheological modifier in the food industry. This paper reports a method to extract the pectin-rich fraction (PF) with a mediate degree of esterification of 51.66% from blueberry wine pomace and provides insight into its relationship between the structure and rheological properties. The impacts of related extrinsic factors, such as sucrose, ions and pH, were also studied in view of food ...

A review on selection of fermentative microorganisms for functional foods and beverages: the production and future perspectives

Fermentation has been employed as a traditional means of improving the shelf life and nutritional contents of foods, thus making fermented foods and beverages functional and therapeutic. Lactic acid bacteria (LAB) plays a major role in determining the health benefits of fermented milk and related products. This review takes into cognizance numerous investigations reporting certain microbial strains and mixes to contribute safety, quality, stability, health and organoleptic properties to ferme...

Human colonic microbiota modulation and branched chain fatty acids production affected by soy protein hydrolysate

Several functional properties have been attributed to soy protein hydrolysates (SPHs); however, their gut fermentation needs to be investigated. This study aimed to determine the effect of hypo-allergic pepsineduced SPH on the growth of gut microbiota, SCFA and BCFA production in a pH-controlled, stirred, batch culture fermentation system compared with commercial SPH and soy protein isolate (SPI). The results showed that all substrates affected gut bacteria. SPH selectively increased the n...

REAL-TIME DRUG INTERACTION, VERIFICATION AND AUTHENTICATION

Counterfeiting is the concern of everyone – the consumers and the manufacturers alike. Drugs counterfeiting has been on the increased, the market is not sought for and the income is on the high side but to the detriment of both the consumers, suppliers and manufacturers. Technology can be of utmost importance in this area via the development of an interacting and authenticating system with a database that will authenticate drugs. The drug interacting authenticating systems will confi...

VIBRATION ANALYSIS OF PIPELINE SUPPORTED BEAMON ELASTIC FOUNDATION USING FOURIER TRANSFORM METHOD

ABSTRACTElastic foundation can be refered to as soil surface that can expand and assume its original position on application of force. Numerous research works has been carried out on pipeline supported beam using different method of analysis such as Differential Transform Method, Finite difference Method Finite Quadrature Element Method and so on. This work examines the vibration analysis of pipeline supported beam on elastic foundation using Fourier Transform Method in form of non-prismatic...

MICROBIAL QUALITY ASSESSMENT OF LOCALLY PRODUCED KUNU SOLD AT TANKE AREA OF ILORIN METROPOLIS

Nine samples of freshly prepared kunu was taken from local vendors and hawkers at Tanke area, Ilorin, Kara State and analyzed for microbial quality. The pH of the samples ranged from 2.66 to 4.06. The total bacterial count ranged from 1.5×104 to 7.4×104 cfu/ml; the total coliform count ranged from 1.0x102 to 8.0x103cfu/ml; the faecal coliform count ranged from 0 to 3.0x103cfu/ml; the total fungi count ranged from 3.2x104 to 2.7x105cfu/ml. The presence of high microbial load was an indicatio...

Molecular Docking and Structure Based Drug Design

Docking is a structure-based technique which attempts to find the “best” match, between two molecules. Molecular docking can be thought of as a problem of “lock-and-key”, in which one wants to find the correct relative orientation of the “key” which will open up the “lock” (where on the surface of the lock is the key hole, which direction to turn the key after it is inserted, etc.). The explosion of structural informatics, genomics and proteomic plays a major role in leading t...

ANALYSIS OF THE NUTRITIONAL VALUES OF FEED COMPOUNDED FROM LOCALLY AVAILABLE MATERIALS (UNIVERSITY OF CALABAR FISH FARM AS A CASE STUDY)

ABSTRACT This project details the results of a research work carried out to develop fish feed compounded from locally available materials in the institute of oceanography fish farm and analyzed its nutritional values, in the biochemistry department all in the University of Calabar. On the basis of the feed production, it is recommended that the  feeding regime of the animal (fish) for intended culture is known, a dry diet formulation of two distinct feed lines was produced (fingerli...

A COMPARATIVE STUDY OF STUDENTS ACADEMIC CONCEPTS USING JAMB SCORES AND CGPA, (A CASE OF BENUE STATE UNIVERSITY, MAKURDI)

ABSTRACTThis research compare the students’ academic performance using JAMB scores and CGPA inBenue state University Makurdi, and the level at which the divergence in grades started is ofparamount importance. Two faculties in the institution were selected. The multiple regressionanalysis carried  out  shows that  JAMB scores as  well as  yearly  GPAs can predict  the  finalCGPA. From the student (t) distribution it was observed that the model contribu...

THE DESIGN AND CONSTRUCTION OF AN ANTENNA BOOSTER (WI-FI ANTENNA BOOSTER)

ABSTRACT   Wi-Fi signals are susceptible to signal loss as they travel hence Wi-Fi users are rarely completely satisfied with the signal strength offered by the off-the-shelf Wi-Fi cards, routers and access points. This project research intends to introduce a device which can provide Wi-Fi users with high signal strength and at a lower cost in order to enable them have a seamless, uninterrupted and reliable communication. This project includes the steps for Biquad antenna constructi...

NUTRITIONAL AND ANTI-NUTRITIONAL CONTENTS OF INGREDIENTS USED IN PREPARING GRANULATED DUMPLING (DAMBU)

ABSTRACTNutritional and antinutritional content of ingredient used in preparing dambu were determined by proximate composition, vitamins, minerals and antinutritional contents analysis. Maize and Moringa flowers were used as the experimental samples and the work was conducted in triplicate which resulted in obtaining the experimental result in mean and standard deviation. Appreciable amount of nutritive composition were obtain in the used maize and Moringa samples. While the antinutritional c...

THE ADAMS-BASHFORTH ITERATIVE SCHEME FOR INITIAL VALUE PROBLEMS
