DESIGN AND IMPLEMENTATION OF BIO SECURITY SYSTEM (A CASE STUDY OF FIRST BANK PLC OWERRI)

ABSTRACT Biometric recognition is the use of individual biometric characteristics, such as fingerprint, face, and signature for automatically computerized recognition systems. Fingerprints are the most widely used form of biometric recognition system successfully. However, fingerprint images are rarely of perfect quality. They may be degraded and corrupted due to variations in skin and impression conditions. Thus, image enhancement techniques are employed prior to minutiae extraction to obta...

EXOSMOSIS AND ENDOSMOSIS VERIFIICATION USING WHITE RAW EGGS

ABSTRACT Exosmosis and endosmosis verification using white raw eggs have been carried out. Two beakers of dilute hydrochloric (HCl) acid solution were prepared. Two white eggs were placed differently into beakers labelled Beaker A and B respectively containing dilute hydrochloric (HCl) solution and left for five hours. Beaker A (containing Saltwater) was seen as more concentrated than the albumin in the egg. Water molecules moved from a low concentration point (albumin) to the high concentrat...

ASSESSMENT OF THE EFFECTS OF CARBONATED DRINKS ON THE ENAMEL OF THE TEETH

ABSTRACT Assessment of the effects of carbonated drinks on the teeth have been carried out. Five white shelled hard-boiled eggs were placed in clear cups and labelled (Soda Drink, Diet Coke, Coke, Tap Water and Vinegar), with the respective selected liquid poured into the cups and ensured the liquid covers the eggs placed in the cups. The eggs were allowed to sit for 72 hours. At 72 hours the eggs were removed from the cups for inspection. The egg in water showed no changes, this is because t...

Antimicrobial Activity of Azadirachta Indica (Neem) Against Bacteria Isolated from Urinary Tract Infected Patients in Khartoum State

Abstract This was analytical study conducted during the period from January to April 2017, to determine the antimicrobial activity of Azadirachta indica leaves methanolic extract against different bacteria isolated from urinary tract infection. A total of 130 urine samples were collected from patients with Urinary tract infection. These specimens were inoculated into Cystine Lactose Electrolyte Deficiency (CLED) media and incubated aerobically at 37 C for 24 hrs. The clinical isolates were th...

Constituents of Celery (Apium graveolens ) Seed Oil and its Biological Activity

Abstract This study was aimed to extract the fixed oil of Apium graveolens through the process of maceration with normal hexane. The oil was analyzed by gas chromatography-mass spectrometry. The antimicrobial activity was also estimated. The GC-MS analysis of the studied oil showed the presence of 45 constituents. Major components are: i) 9-Octadecenoic acid methyl ester (56.04%) ii) 9, 12-Octadecadienoic acid methyl ester (13.47%) iii) Hexadecanoic acid methyl ester(12.05%) iv) Methyl steara...

Characterization of Flavonoids from Albizia Amara Leaves and Their Biological Activity on Microbes

Abstract Phytochemical screening of methanol extract of leaves of Albizia Amara revealed the presence of secondary metabolites: saponins, alkaloids, tannins, glycosides and flavonoids. Powdered shade- dried leaves (1kg) of A. amara. were extracted with 95% ethanol at room temperature for 48 hours, The crude extract was suspended in water and partitioned with organic solvents in order of increasing polarity, petroleum ether, chloroform ethyl acetate and n-butanol, three compounds were isolated...

Assessment of the Effect of Addition of Baobab ( Adansonia Digitata L.) Fruit Pulp on Properties of Camel Milk Yoghurt

Abstract This study was carried out to investigate the effect of Baobab fruit pulp on the physicochemical and microbiological properties of yoghurt made from camel milk and cow milk. Yoghurt was made from camel milk and cow milk with Baobab fruit pulp (5g/L, 10g/L, 15g/L, and 20g/L). Starter culture was added at rate of 3 % (v: v) and stored for 10 days at 4ᵒC. Physicochemical and microbial (acidity, pH, total solids, solids not fat, ash, protein, Fat, lactose, moisture, crude fiber, synere...

Bioethanol Production from Sorghum Grains

Abstract A biofuel is a fuel that produced through contemporary biological processes such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes. It can be derived directly from plants or indirectly from agriculture or industrial waste. Bioethanol is an alcohol made by fermentation, it is produced from sugar or starch crops such as corn, sugar cane or sweet sorghum. Biodiesel and ethanol can be used as fuel for vehicles in its pure form but it is usually u...

Structural and Optical Properties of ZnO Nano-Powder Synthesized by Combustion and Sol-gel Method

Abstract Nowadays, ZnO is considered as the most important chemical compounds due their distinctive properties owing to its wide band gab and large exciton binding energy. It is well known that the structural and the optical properties of ZnO differ by different methods of preparation. Therefore, in this work, ZnO power was prepared by two methods, namely sol-gel and combustion method with the aim of comparison. The obtained samples from both methods were investigated by many techniques for c...

Sero-prevalence of Hepatitis B Virus among Pregnant Women in Red Sea State

ABSTRACT Hepatitis B Virus (HBV) occurs worldwide with more than 2 billion people being infected at some time in their lives. Transmission of this virus from carrier mothers to babies can occur during perinatal period. This study was conducted to determine prevalence of HBV infection among pregnant women in Rea Sea State. The study was carried out during the period from April to July 2017. A total of ninety one (n=91) pregnant women were enrolled in this study. Sociodemographic data including...

A Design of an Econometric Model for Evaluating the Security in Cloud Computing Environment

ABSTRACT Cloud computing offers an innovative business model for all cloud enterprises to serve IT services with no need to have technical details. The extreme growth of cloud usage increases the probability of threats occurrence, which in turn leads to financial and other losses. So there is a need to use appropriate metrics to assess the failure cost among cloud stakeholders according to their different needs; we propose a measure called “Mean Failure Cost” (MFC) which quantifies the im...

Antimicrobial and Antioxidant Activity of Hibiscus sabdariffa (Roselle) against Selected Microorganisms

Introduction: Prevalence of resistant microbial strains is increasing with time; due to the extensive and indiscriminate use of the broad spectrum antimicrobial drugs that render the current used antimicrobial agents insufficient to control some microbial infections. Objective: The present study was aimed to investigate the antimicrobial and antioxidant potential of methanolic extract of the medicinal plant Hibiscus sabdariffa L. Method: The agar well diffusion technique was used to determin...
