Previous studies have demonstrated that passage of pathogenic bacteria on increasing concentrations of the antibiotic rifampicin leads to the attenuation of virulence and these resistant strains may serve as live attenuated vaccines. Two rifampicin resistant strains of Flavobacterium psychrophilum, 259-93A.16 and 259-93B.17, were generated by passage on TYES plates containing increasing concent...

The capacity of Multiple Input Multiple Output (MIMO) communication systems depends on the spatial properties of the MIMOchannel. This work shows how in particular partial correlation of channel coefficients affects the capacity of the system. For partially correlated channel coefficients the performance of such systems can be further be enhanced by the use of channel knowledge at the transmitt...

The evolution of the gauge coupling is modelled using a scalar degree of freedom whose homogeneous and inhomogeneous modes evolve from an ordinary inflationary phase to the subsequent epochs. Depending upon various parameters (scalar mass, curvature scale at the end of inflation and at the onset of the radiation epoch), the two-point function of the magnetic inhomogeneities grows during the de ...

Objectives: (i) To expose ‘normal sleepers’ to a thirty two hour sleep deprivation protocol and evaluate the impact of this deprivation on a complex performance task i.e. The Paced Auditory Serial Addition Test (PASAT), (ii) To compare these sleep deprivation performance findings with historical data on the impact of sleepiness secondary to narcolepsy on PASAT performance measures, (iii) To inv...

Results: Maximum oxygen uptake was significantly correlated with 6 minute walking distance. Both exercise tests were correlated with pulmonary function tests. However, maximum exercise capacity was more closely correlated with measures of lung function than 6MWT. Both tests were significantly correlated with static lung volumes. Inspiratory capacity (IC) was significantly correlated with 6MWT a...

In BitTorrent, the data to be shared is divided into many equal-sized portions called pieces. Each piece is further sub-divided into equal-sized sub-pieces called blocks. All clients interested in sharing this data are grouped into a swarm, each of which is managed by a central entity called the tracker. Each client independently finds a file, called a torrent, that contains the location of the...

Studies were conducted during August and March–April in the Sargasso Sea south of Bermuda to examine rates of bacterial growth and picoplankton consumption by microbial consumers. Bacterial growth rates were estimated from [3H]thymidine (TdR) incorporation rates, while grazing rates were determined using fluorescently labeled prey (FLP). In addition, net bacterial growth rates were calculated f...
