A comparative study of antibacterial properties of Elephantorrhiza elephantine (Muzezapasi) and Zanthoxylum chalybeum (Mukundanyoka) against those of commercial drug Azithromycin on Escherich

Abstract A study was carried out at the Midlands State University during the month of September 2016, to compare the antibacterial properties of Elephantorrhiza elephantine (Muzezapasi) and Zanthoxylum chalybeum (Mukundanyoka), against those of the commercial drug Azithromycin on Escherichia coli. Plant extracts were purchased, sun dried and ground into fine powders. Azithromycin tablets were also purchased. Escherichia coli bacteria were isolated from the University toilets. Confirmatory tes...

An Assessment Of Fertility Rate And Differentials In Women Within The Reproductive Age in Kaduna State

ABSTRACT This dissertation looked at the fertility rate, fertility pattern and some of the diseases that cause fertility problems which leads to pregnancy wastage and fertility differentials in women within the reproductive age using binary Logistic and Multiple regression. The result shows that the average Total Fertility Rate (TFR) of sample I, sample II and sample III are approximately five (5) children per woman, seven(7) children and six (6) children respectively. The histogram and ...

Determinants Of Economic Growth In Nigeria: An Autoregressive Distributed Lag (Ardl) Modeling Approach

ABSTRACT The research also examines the relationship between the ARDL procedure and the fully modified OLS approach of Phillips and Hansen to estimation of cointegrating relationship between all the variables, and economic growth, these results provide strong evidence in favor of a rehabilitation of the traditional ARDL approach to time Series econometric modelling. The ARDL approach has the additional advantage of yielding consistent estimates of the long-run co-efficient that is asympt...

An Assessment Of Government Effort On The Provision Of Portable Water Supply In Bida Local Government Area Of Niger State

ABSTRACT In this study attempt was made to asses government effort in the provision of portable water water supply in Bida local government area. The study investigates the extent and condition of water supply as well as source of portable water in the study area. However, in the course of the study, questionnaire was developed and used to generate data. The data obtain from the administration of questionnaire was presented and analyzed using both descriptive and influential statistics. The s...

The Socio-Economic Impact Of Zobe Dam On It’s Neighbouring Environment

ABSTRACT This research work examines the socio-economic impact of Zobe Dam on its neighboring environment. Specific objectives includes how the construction of the dam has brought about changes in farming techniques, their standard of living and its potential contribution to the overall development of the area. The problem hinges on how the construction of dam has triggered changes in farming techniques in the area. The proposed hypothesis (Ho) that: there is no relationship between Zobe Dam ...

Design And Construction Of A Micro-Controller Based Automatic Fire Extinguishing System

ABSTRACT Despite many buildings have fire fighting systems installed in them; many people are still losing their lives and properties due to fire accidents. In this research, an automatic cost effective device for the detection and control of fire has been designed and constructed. The system has an additional feature of sending signal to a pump/sprinkler through a relay. It is made up of two sensors, microcontroller, buzzer and a controlled fire fighting equipment (pump/sprinkler). LM 3...

Experimental Infections Of Biomphalaria Glabrata, B.Pfeiferi And B.Sudanica With Schistosoma Mansoni

ABSTRACT A laboratory study was carried out to determine quantitatively the degree of compatibility between Biomphalaria glabrata, B. pfeifferi and B. sudanica and Schistosoma mansoni. The effect of host diet and mode of exposure to miracidia, continuous darkness, origin of host species and parasites strains, miracidial dosage level, age and intensity of primary infection in dual infections were examined by measuring snail survival, growth, fecundity, prepatent period, infection rate and cerc...

Design and characterisation of a microstrip patch antenna for Wi-Fi

Abstract In recent years, the inventions in communication systems require the development of low cost, minimal weight, compact and low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort in the design of micro strip patch antennas because of its inherent characteristics that fits the requirements of modern communication devices. This dissertation presents the design and simulation of a compact ...

Implementation And Building Of Cheaper Signal Conditioners & A Pid Controller Block Using A Plc

Abstract The proportional, integral and derivative (PID) technique is a reliable and widely used art to control and regulate complex processes. The PID block and signal conditioners are constructed by hand inside a small memory Schneider PLC without inbuilt process control loops using software. Analogue input module of the PLC receives the analogue unconditioned signal from the rtd/thermocouple sensor, passes it through the signal conditioning phase to the pid block. The PID block executes th...

Evaluation Of The Genotoxicity Of Antiretroviral Drugs On Allium Cepa And Male Fertility In Two Generations Of Mice

ABSTRACT The potential of the antiretroviral drugs zidovudine and nevirapine to induce genotoxicity was evaluated using the Allium cepa and the mice models. Four doses per antiretroviral were used in the Allium cepa chromosomal aberration assay while three doses per antiretroviral were used for the mouse study. The Allium cepa study consisted of the 96hr root growth inhibition, the 48hr recovery and the 48hr chromosomal aberration phases to determine the EC50; ascertain if root growth inhibi...

Evaluation Of Glycine Max (L. Merrill) And Lycopersicon Esculentum (Mill) In Remediation Of Crude Oil Polluted Soil

ABSTRACT The potentials of using Gycine max and Lycopersicon esculentum in remediating soil polluted with crude oil were investigated. The investigation involved screening of four accessions each of the two crops fro germination, survival and growth. The mitotic divisons of the accessions of G. max were further examined. The plant height, dry matter content, leaf area, chlorophyll content and pod production rate of the TGX 1440-1E accession of G. Max was also accessed. This was followed by in...

The Teaching And Learning Of Slow Learners In Mathematics At Secondary School Level In Gweru Zimbabwe

ABSTRACT This study focused on the teaching and learning of slow learners in mathematics at secondary school level in secondary and high schools in Gweru Urban District. The researcher's main objective was to find out how slow learners in mathematics are being assisted at secondary school levels, the challenges, if any, which are being faced by the teachers in assisting these slow learners as well as the slow learners' perspectives towards the assistance they are being given by their mathemat...

Implementation Of An Integrated Traffic Fine Information System For Namibia

ABSTRACT The Government of the Republic of Namibia as a multi-layered organisation of systems, desires to be effective, efficient and integrated in service delivery. Although it continues to invest significantly in the acquisition and development of information systems, active results and efficiency are not necessarily produced as expected. A concern in public roads traffic control are the various traffic fine information systems involved, which are heterogeneous and decentralised. This has c...

Designing an Interactive Game for Preventing Online Child Abuse in Namibia

ABSTRACT In the wake of digitalisation, technology has changed the world, connecting people with information and services at the touch of a finger.
