Introducing Microcells into Macrocellular Networks: A Case Study
No full textAbstract?The performance in terms of signal-to-interference ratio (SIR), teletraffic, and spectral efficiency of a combined macrocellular and microcellular network is investigated when either both types of cells share the same channel set, or when the channel set is partitioned between the macrocells and the microcells. The analysis is for time-division multiple access (TDMA) with frequency hopping, power control, and discontinuous transmission, and the radio channel is composed of an inverse fourth-power path loss law with log-normal fading. We commence by introducing a single microcell into a hexagonal cluster of macrocells before considering clustered microcells. Both omni-directional and sectorized cells are examined. We find that high reuse factors are required when channel sharing is employed. When channel partitioning is used, no co-channel interference occurs between the microcells and the macrocells allowing them to be planned independently. The reuse factors in the microcells and macrocells therefore do not need to be increased beyond conventional values. The outcome is that by opting for channel partitioning, the improvement in spectral efficiency compared to channel sharing is two to three times greater.

Pattern of Coombs’ test reactivity has diagnostic significance in dogs with immune-mediated haemolytic anaemia
No full textObjectives: To investigate the clinical significance of the pattern of Coombs’ test reactivity in dogs with immune-mediated haemolytic anaemia.
Methods: Sixty-five anaemic dogs with a positive Coombs’ test were included. Coombs’ testing was performed at 4 and 37°C with polyvalent canine Coombs’ reagent and antisera specific for each of canine immunoglobulin G, immunoglobulin M and complement factor C3. The impact of performing testing with only polyvalent antiserum at 37°C was assessed. Chi-squared tests were used to compare Coombs’ test reactivity in dogs with primary immune-mediated haemolytic anaemia (group A) and in dogs with concurrent/underlying disease (group B). Following Bonferroni correction, significance was set at P≤0·003.
Results: Eleven dogs would have been regarded as Coombs’ negative had they been tested with polyvalent antiserum at 37°C alone. Group A dogs were significantly more likely to be positive with polyvalent antiserum and/or anti-dog immunoglobulin G at 4 and/or 37°C (P≤0·001) and tended to be less likely to be positive with anti-dog immunoglobulin M at 4°C (P=0·040).
Clinical Significance: Testing of anaemic dogs with polyvalent Coombs’ reagent at 37°C was less sensitive than testing with monovalent reagents at 4 and 37°C. The pattern of Coombs’ test reactivity differed significantly between dogs with primary immune-mediated haemolytic anaemia and those with concurrent/underlying disease

Terrace outside the tearoom at the H C Coombs Building (Research Schools of Social Sciences and Pacific Studies)
No full textThe terrace outside the tearoom of H C Coombs Building looks onto one of the building's landscaped courtyards. The courtyards are in the centre of the open hexagons which comprise the building's two wings, one housing the Research School of Social Sciences and the other housing the Research School of Pacific Studies. The H C Coombs building was opened by the Chancellor, Sir John Cockroft, on 11 September 1964
