Electronic Energy Meter Management System (Eemms)

ABSTRACT The core aspect behind developing Electronic Energy Meter Management System (EEMMS) was a result of inefficiency of the manual system that was used at the organization. The main aim was to develop a computerized system that will curb the problems currently encountered by using the existing manual system by integratinginformationsystemsprocess. The instruments which were used to come up with the system include MySQL database, Adobe Dreamweaver CS6, SMTP email service and Apache server...

Prevalence And Predictors Of Vitamin A Status Of Children Aged 6-23 Months In Bungoma And Busia Counties Of Western Kenya

ABSTRACT Subclinical vitamin A (VA) deficiency (VAD) continues to be a global problem widely affecting children within 1,000 days of life. Western Kenya experiences high infant mortality partly attributable to VAD. A community based cross-sectional survey among children 6-23 months was undertaken in Western Kenya. Socio-demographic and dietary intake information were collected. Analysis of retinol-binding protein (RBP) and C-reactive protein (CRP) was undertaken to estimate VA and sub-clinica...

EVALUATION OF α-AMYLASE AND α-GLUCOSIDASE INHIBITORY COMPOUNDS FROM Zanthoxylum chalybeum STEM AND ROOT BARK

ABSTRACT Management of diabetes mellitus using conventional drugs is either unaffordable, unavailable or has undesirable side effects. Medicinal plants such as Zanthoxylum chalybeum (Rutaceae) have found prominence in management of diabetes and previous studies showed the efficacies of aqueous root and stem bark against in vivo alloxan and streptozotocin–induced diabetes in rats. However, the phytochemical evidence for these activities was never established. Therefore, this study was to est...

SUSCEPTIBILITY PATTERNS AND TOLERANCE MECHANISMS OF Staphylococcus epidermidis BIOFILMS TO PHYSICO-CHEMICAL STRESS EXPOSURE

ABSTRACT Bacterial biofilms remain a major public health burden. Staphylococcus epidermidis biofilm is the predominant cause of biofilm-associated infections. Kisumu county has a high circulation of antibiotic resistance genes, which is attributable to S. epidermidis biofilm, necessitating effective S. epidermidis biofilm control. Given the high tendency of bacteria to develop resistance to antibiotics, S. epidermidis biofilm control using physico-chemical disinfection is a suitable approach....

Prevalence And Characteristics Of Aeromonas Species And Plesiomonas Shigelloides In Lagos

ABSTRACT This study was carried out in two phases. The first phase involved the determination of the prevalence of Aeromonas species and Plesiomonas shigelloides in patients, with and without diarrhoea, reporting at the enteric laboratory of the Department of Medical Microbiology and Parasitology, Lagos University Teaching Hospital (LUTH), Idi-Araba, Lagos; over a 12-month period of October 1986 through September 1987. In the second phase the characteristics of isolates thus obtained were exa...

Plasmodium Yoelii Nigeriensis Infection And Immune Response In Mice And Rats

ABSTRACT The Biology or Plasmodium yoelii nigeriensis in rodents and the reaction of rats and nice to the infection were studied. In investigations into the course of infection of Plasmodium Yoelii nigeriansis. in rats and nice, it was found that adult nice, baby nice and baby rats were susceptible to the infection, while adult rats were totally resistant. The infection was rapidly fatal in both adult and baby mice while in baby rats, it was tolerated until the animals were 7 weeks old, after...

Physiological Adaptations To Aestivation And Osmotic Regulation Of The African Lungfish, Protopterus Annectens (Owen) Of Anambra River, Nigeria

ABSTRACT Physiological adaptations to aestivation and osmotic regulation of the African lungfish, Protopterus annectens (Owen, 1839) (Lepidosirenidae) of Anambra River, Nigeria (Lat. 50 42‟ & 70 40‟N and Long. 60 30‟ & 70 42‟E) were investigated. Some physico-chemical parameters of Anambra River and aestivation habits of P. annectens in the river and its flood plains were also determined, as well as the seasonal changes in gonadosomatic and hepatosomatic indices, condition factor, fe...

Oblique Incidence Ionospheric Absorption Near The Magnetic Equator

Abstract Measurement of equatorial ionospheric absorption made by the A3 Method for quiet conditions near a period of maximum solar activity (1979 to 1981) are used for a detailed examination of Absorption of Radio Waves in equatorial Ionosphere. Assuming an index law of the form L. 1.Cos"for the absorption (x being zenith angle of the sun). the diurnal and seasonal characteristics of the variation are obtained for two frequencies (4.9 Mhz and 7.1 MHz) and compared with existing theories. Pro...

Nitrate-Nitrite, Vitamin C And In-Vitro Methemoglobin Formation From Some Vegetables

ABSTRACT The content of nitrate, nitrite and Vitamin C in eleven samples of fresh vegetables were determined. The levels of nitrate were beyond here on recommended in six of the vegetables, namely: Celosia sp. Lactuca, sativa , Amaranthus hybridus, Brassica oleracea variety acephala, Talinum sp, Spinacia oleracea. Minute quantifies of nitrite were detected in Celosia sp and Daucus carota. With accompanying high concentration of Vitamin C (a reducing agent) present in Celosia sp. this vegetabl...

Molecular Heterogeneity In The Mycobacterium Tuberculosis Complex Isolated From Lagos, Abuja And Kano, Nigeria

ABSTRACT The Mycobacterium tuberculosis complex (MTBC) is the causative agent of human and animal tuberculosis (TB). Complex membership signify how closely related they are clonally. Since the true nature of an organism lies within the genes, this molecular-based study explored unique regions of variation or polymorphism within the chromosomes that serve as targets for differentiaton, to improve our understanding of this unique group of bacteria. While extensive data exist for the molecular c...

Microbial Quality Management And Shelf Life Determination Of Water-Based Paints

ABSTRACT The microbial quality of materials and final products of Chemical and Allied Products Limited (CAPL), rentable paint industry in Lagos area were analyzed. The bacterial population in the fresh paint samples monitored at two weeks intervals for a period of ten months ranged from 16x 10 - 7x10 ml while the fungal population ranged from 10 x 10-55 x 10 cfu/ml. The isolated bacterial sits were identified as Bacillus polymyxa, B. brevis, B.laterosporus, Proteus mirabilis, Escherichia coli...

Decolourisation And Biodegradation Of Textile Reactive Azo Dyes By A Strain Of Proteus Mirabilis

ABSTRACT The discharge of coloured wastewaters into water-bodies has serious implications for the environmental and public health. Furthermore, the usual colour removal methods often result in aromatic amines which are toxic, mutagenic and carcinogenic. Developing a method that can both decolourise azo dyes and degrade the corresponding aromatic amines formed is expedient. In this study, the ability of newly isolated indigenous bacteria to decolourise textile/non-textile azo dyes and degrade ...

A Framework for Implementing Cloud Based Enterprise Resource Planning (ERP) in the Transport Business Sector in Zimbabwe.

ABSTRACT This study sought to develop a framework for the implementation of cloud based Enterprise Resource Planning (ERP) system in the transport business sector in Zimbabwe: A case of CMED (Pvt) Ltd. Information was gathered through interviews, questionnaire and case study approaches. The concept of cloud computing is not new in the transport business but it was used for telematics only not for integrated system like ERP. An Enterprise Resource Planning (ERP) system is an enterprise-wide so...

Riozim Extranet Procurement System

ABSTRACT This research gives a detailed overview of the Extranet Procurement System with the main thrust of identifying problems, summarizing facts, identifying and analyzing alternatives. Riozim has suffered data redundancies problems, human errors, fraud and biases in terms of choosing the best supplier, costs of employing much labor to manage every activity that was involved in the process, the system is rapacious thereby time consuming and may affects production and stimulates costs and a...
