Lin (1996) gave the definition of an information system as " (is) a set of interrelated components that collect, process, store, and distribute information to suppor...

Automated Pension and Gratuity System

ABSTRACT  Information technology is increasingly being used in the office, factory, shop, home, supermarket and in many other places. It is being used to carry out transactions, provide information, record data, perform an ever increasing range of tasks and even in making decisions. This means that with the development of information technology, many manual operations are being converted to modern automated systems. The new development does not elude pension and gratuity system. Pension ...

Atomic Absorption Spectrophotometry Determination of Some Heavy Metals in Chocolates and Candies Purchased from Abuja Municipal Area Council.

ABSTRACT  The Cu, Pb, Zn and Mn content of ten chocolates and candies purchased from Abuja municipal aiea council were determined by Atomic Absorption Spectrometry (AAS). The HN03 digestion method was evaluated by the analysis of the ten replicates of the candies and chocolate which gave a precision of 2%, 3%, 17% and 2% for Cu, Mn, Ni and Zn respectively. The results of the analysis showed that the mean metal levels in the chocolate and candy samples were Ni 0.077+0.0µglg Cu/0.26±0.05...

Atomic Absorption Spectrophotometric Determination of' Trace, Metal Concentrations in Raw and Finished Drinking Water from Lower Usuma Dam in The F.C.T.

ABSTRACT The concentrations of Fe, Zn, Cu, Pb and Cd in vegetables grown in Kaduna metropolis were determined. The nitric acid -per chloric acid mixture was used in the digestion procedure and a precision of 4.2%, 3.8%, 2.4%, 5.3%, and 5.7% was obtained for Fe, Zn, Cu, Pb and Cu respectively. Good recoveries between 88-96% were obtained for the metals studied. The concentrations of metals in the vegetables varied from 40-1 OOµg/g for Fe, 21.3-51.3µg/g Zn, 9.0-28. Oµg/g Cu, 0.7-2.6µg/g Pb...

Atomic Absorption Spectrophotometric ' Determination of Zn, Fe, Cu, Cd, And Pb Concentration in Canned Foods Sold in Abuja Municipality

ABSTRACT The concentrations of some trace metals (zinc, iron, copper, cadmium and lead) in 51 canned foods (fish, vegetable and fruit juice) samples purchased within Abuja Municipal Area Council (Nigeria) were determined using the flame atomic absorption spectrophotometry (FAAS). The wet oxidation procedure of HN03-H20 2 was used in the preparation of the samples. The ranges obtained for trace metals analyzed in ug/g are as follows: Canned fish: Zn (19.15±0.8-32.50±0.3), Fe (17.92± 1.2 --...

Atomic Absorption Spectrophotometric Determination of Trace Metals in the Soils of Abuja Municipality Nigeria

CHAPTER ONEINTRODUCTION 1.1   General Pollution affects more than our water and air; soils also are seriously polluted. It is easy to forget that the soil is more than just a mass of inert matter. In its own way, the soil is a living organism. (I) Soil is a crucial component of the rural and urban environments, and in both cases, land management is the key to soil quality. Pesticides are synthetic organic or inorganic chemicals used to control weeds in fields and lawns, and unwanted...

Assessment of Phytochemical and Nutrient Compositions of Edible Yam Species in Southeastern Nigeria

ABSTRACT This study assessed the phytochemical and nutrient compositions of edible yam species Dioscorea rotundata 1, Dioscorea rotundata 2, Dioscorea rotundata 3, Dioscuri rotundata 4, Dioscorea Cayenensis, Dioscorea alata, Dioscorea dumentorum and Dioscorea bulbifera in Southeastern Nigeria. The phytochemical and nutrient (proximate, minerals, vitamins, fatty acids and amino acids) compositions of the yam tubers were investigated using standard analytical methods. 

Assessment of Level of Heavy Metal in Soil and Their Environmental Effects from Three Mechanic Villages in Abuja

ABSTRACT This research work is aimed at assessment of levels of heavy metals in soils and their environmental effects from three Mechanic Villages in Abuja namely; Apo, Kugbo and Zuba. To achieve the set target, soil samples were collected from five sampling points in each of the mechanic villages to a depth range of 0 - 15 cm with a stainless hand-dug auger. A control sample was also taken from a point of approximately 100 km where neither industrial nor commercial activities take place. Re...

Assessing Water Quality for Human Consumption Within the Vicinity of Karu Aiiattoir, Abuja Fct, Nigeria

ABSTRACT This study assesses the surface and groundwater quality for human consumption within the vicinity of Karu abattoir in Abuja. Water samples were collected from three points along Tauga stream, comprising the discharge point, 40meters before (upstream) and after (downstream) the discharge point. Groundwater samples were also collected around the abattoir, comprising the abattoir vicinity (Group A), 60meters from the abattoir (Group B) and 200-300meters from the abattoir (Group C). The...

Assessing The Impacts Of Urbanization On The Environment Of Abuja Municipal Area Council (AMAC)

ABSTRACT Rapid urbane without effective environmental consciousness means that in virtually every matter - from large cities and metropolitan areas to regional centers and ss ret towns - a substantial proportion of the population is at risk from nature an-induced environmental hazards. A strategic approach is essential if urbane to enjoy all the benefits which nature can bring. This paper evaluates the urbanization on federal capital territory environment. It is concentrating. a district of ...

Aquifer Hydraulic Characteristics and Vulnerability Estimation from Vertical Electrical Sounding: Case Study of Oru and Environs, South-Eastern, Nigeria

ABSTRACT Aquifer Hydraulic Characteristics and Vulnerability Estimation from Vertical Electrical Sounding: A Case Study of Oru and its Environs, South-Eastern, Nigeria was carried out to delineate the different aquifer units with a view to determine the vulnerability of groundwater in the area. The study area is underlain by the Benin Formation which is within the Niger Delta Basin. Twenty-Seven (27) VES data were acquired using a Schlumberger array with a maximum electrode separation of AB/...

Applications of Computer On Airport Customs Station (Nigeria Customs Service) A Case Study Of Nnamdi Azikiwe International Airport Abuja

Many physical processes are expensive or impracticable to observe directly, and certainly they can only be observed in operation under conditions that actually exist. Almost any industrial process, almost any natural biological, physical, or social environment, and almost any large computing system is quite complex. Such as, building a large chemical plant based on a newly discovered sequence of reactions without knowing that it will work on a large scale much as it does in the laboratory wou...

Application of Computer Programming to Linear Programming Problems (Simplex Method)

ABSTRACT The allocation of limited resources and competing demands is the most prevalent problem in organisation. Mathematical programming is the general term for a host of mathematical techniques developed to solve problems involving resource allocation. Linear programming is the most popular and most widely applied technique. Although linear programming has been applied to a wide variety of business problems, it has been developed most fully and used frequently in production problems. Acco...

Application of Computer Graphics in Presentation of Statistical Data

ABSTRACT This project is focus on the application of computer graphics in presentation of statistical data. The data ;1owever, is formatted to suit the purpose as demanded for presentation in the form of Pie chart and Bar cha1i. Each of the charts is used to give certain information about the data in pictorial form. Pie chart portrays the components of data and provides highlight on their relative magnitude. On the other hand, bar chart serves for comparison of characters of events, which co...

Antimicrobial Efficacy Of Guava (Pisdium Guajava) And Orange (Citrus Sinensis) Stems Extract Against Streptococcus Mutans And Candida Albicans

ABSTRACT   This research was conducted in Microbiology Laboratory of Godfrey Okoye University to determine the antimicrobial efficacy of aqueous, methanol, ethanol of Pisdium guajava and Citrus x sinensis on the pathogenic Streptococcus mutans and Candida albicans. The Dimethyl sulfoxide was used for dissolving the plant extracts. Pisdium guajava showed antimicrobial activity against C. albicans with the exception of methanol showing no zone of inhibition to any of the isolates. The aque...
