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...
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...
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...

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 ...

Thanks to increasing advances in wireless communications devices, the number of mobile users has g...
ABSTRACT The past decade has been characterised by many firms migrating to clouding services which are powered by data centres. This led to a vast growth rate in the number of data centres in the world and as a result data centers became the most energy-consuming facilities. Researches conducted by different scholars reflected that these energy consumptions can be reduced by using free cooling in data centers and raising the data center operating temperatures but however both methods result ...
