Radio Frequency Based Home Automation System

Abstract The need for a remote control system that can control domestic appliances and various lighting points and sockets has often been a concern for users. At times users find it inconvenient and time consuming to go around turning their appliances on or off each time there is power outage or each time they are leaving the house for work. It has also often led to damage of appliances due to the fact that an appliance was not turned off before leaving the house. The Objective of putting up...

Design And Implementation of a Gsm Based Weather Station.

ABSTRACT A wireless remote weather station is an ideal solution for knowing the weather conditions at a specific remote location. Weather forecasts are informative, but they are only a forecast. With a Remote Weather Station, one would always know the exact weather conditions from where ever the Remote Weather Station is located. This project seeks to devise a simple low-cost microcontroller-based remote weather station that measures weather conditions using sensors to measure temperature, h...

An Investigation Into The Effects Of Storage Periods On Germination Vigour And Malt Quality In Malting Barley (Hordeum Vulgare), Variety “Hope” :A Case Study At Delta Beverages, Kwekwe Maltin

ABSTRACT Malts with high extract values, high enzymatic activities and good modification are fundamental to increase the brewing yield and efficiency. To produce malt that meets these requirements, the barley employed must have minimal post-harvest dormancy and be able to germinate rapidly and uniformly. The aims of this study were to assess the changes in seed germination vigour trends and the general storage stability of a Zimbabwean two-row malting barley variety “Hope” as the post-ha...

Flight Plan Management System

ABSTRACT The purpose of this research was to develop a computerised Flight Plan Management system for Thornhill Air Field to be utilised for their aviation operation. The objective was to align the aviation sector with information system technologies for efficiency and effective operation substituting the manual paper based system. The dynamic changes brought about by the ever changing inventions in technology have greatly impacted the operations of various organisations both positively and ...

Teachers’ perceptions on the use of models in the teaching and learning of geography in gweru urban high schools.

ABSTRACT The study sought to establish teachers’ perceptions on the use of Geographical models in the teaching and learning of Geography in Gweru urban high schools. The study adopted the descriptive survey design which enabled the researcher to collect data through the use of personally distributed questionnaires, personal interviews and observation. The design helped the researcher to elicit valuable knowledge about opinions, attitudes and views on the use of models in teaching Geography...

The Characterization, Antibiotic Sceptibility And Plasmid Profiles Of Coagulase Negative Staphylococci In Lagos

ABSTRACT A total of 745 gram-positive, catalase-positive clustering cocci were obtained from various clinical specimens which included wound, blood, urine, catheter tips, high vaginal and endocervical swabs, urethral swabs, seminal fluids, bone secretions, eye and ear swabs. These isolates were obtained over an 18-month period from the Lagos University Teaching Hospital (LUTH), Idi-Araba, and General Hospital, Ikeja. Swab samples were also obtained from skin, hands, axilla and nose of an appa...

The Challenges Of Tertiary Mathematics In Nigeria's Economic Goals Of Vision 2010

ABSTRACT Nigeria aspires for qualitative education as well as economic prosperity in the year 2010. It is envisaged that there will be a high level of technological sophistication by the twenty-first century world wide. In order not to be left behind there is need for Nigeria to take steps in ensuring high technological advancement as well as having sustainable economic growth. The important role that mathematics plays in science and technology has ensured its inclusion as a compulsory subje...

The Biochemical Studies Of Trypanocidal Activity Of Mitragyna Ciliate Aubrev & Pellegr. (Rubiaceae)

ABSTRACT The extracts of many plants used in traditional medicine in Africa have been shown to contain therapeutic agents supporting their use in the treatment and management of many disease endemic to the region. Trypanosomiasis (sleeping sickness) is one of such diseases that still are a major health challenge in sub-Saharan Africa, in the quest to combat this problem, the search for trypanocidal agents from medicinal plants has arisen. The aim of this study was to investigate and corrobora...

The Application Of Geographic Information Systems (GIS) To Property Rates Administration In Lagos Mainland Nigeria

ABSTRACT Property rate is one of the major sources of internally generated revenue to the Lagos Mainland Local Government (LMLG). However, presently property rate is poorly administered in the area. This is largely as a result of certain human, logistic, technical, environmental and data/information management problems. Consequently, the Local Government loses a significant amount of money, since the annual revenue yield from property rates is often notably low. In this research a computer-ba...

Studies On The Assessment And Simulation Of Dietary And Environmental Exposures To Polycyclic Aromatic Hydrocarbons In Complex Matrices

ABSTRACT Polycyclic aromatic hydrocarbons (PAHs) are known for their carcinogenic and mutagenic properties. They are formed from incomplete combustion of organics such as fossil fuels among others. PAHs are found in foods and in the environment. In this study, the concentration of PAHs and their potential risks were determined in smoked fishes, roasted foods, soils and plant samples in the Lagos metropolis, Nigeria. Smoked and raw fishes (Arius heude loti (catfish), Cynoglossus senegalensis ...

Studies On The Pathogenicity Of Campylobacter Jejuni

SUMMARY Rats experimentally infected with about 10 CFU or more of Campylobacter jejuns were promptly colonized. Campylobacter jejuni was recovered from faecal cultures of infected rats for up to 17 weeks post infection. The infected rats did not succumb to diarrhoea throughout the experiment. Haemagglutination assay was used to detect adhesins of Campylobacter jejuni isolated locally. Five out of 15 (33 percent) of the strains tested agglutinated erythrocytes of human blood group A+ and guine...

Studies On The Antisickling Activities Of Carica Papaya Dried Leaf Extract

ABSTRACT Sickle Cell Anemia (Drepanocytosis) is a genetically inherited disease that affects the red blood cell hemoglobin. In vivo, sickled erythrocytes tend to block capillaries, causing stasis, and thereby starve organs of both nutrients and oxygen and eventually cause hypofunction or complete tissue destruction. In an attempt to find new types of antisickling agents that are cost effective and specifically inhibits the sickling phenomenon without undesirable consequences, this research st...

Studies In Synthesis Of Long Chain Aliphatic Compounds

ABSTRACT This thesis is in two parts. Part I involves a study of the straight chain alkanes containing many carbon atom. These are important analogues of polyethylene, a versatile industrial raw material. Although they can be derived from natural fats or waxes or Prom ethylene oligomers, they are never obtained pure. The physical properties of linear polyethylenes can be better understood if pure paraffing of comperable chain length could be synthesised and analysed. Here long chain aliphatic...

Spatial Distribution Of Atmospheric Pollen And Fungi Spores And Their Relation To Allergy In Nigeria

ABSTRACT The socioeconomic burden of pollen and fungi spores allergy are very high in terms of hospitalization, treatment, lethargy, poor concentration and behavioral changes which impact negatively on adults and children. The study of atmospheric pollen and fungal spores in the six geopolitical zones of Nigeria was carried out from June 2011 to May 2012. The aims of the study are to determine the seasonal prevalence of atmospheric pollen and fungal spores, examine the impacts of weather par...

Simulation Of Ionospheric Irregularities On Transionospheric Radio Systems For The Enhancement Of Safety In The Aviation Industry

ABSTRACT This thesis highlights the role that transionospheric radio propagation (with particular interest on global positioning system (GPS)) plays in enhancing aviation safety. The ionosphere over equatorial latitudes is characterized with high dynamics (irregularities) that may challenge the performance of transionospheric radio system, especially on phenomenal days. The objectives of this work are to: investigate how ionospheric irregularities grow and evolve, and thereafter assess their ...
