    Notes: Summary A single oral dose of atenolol 100 mg was given to 7 hypothyroid patients (4 F, 3 M), before and after correction of hypothyroidism, mean delay 3.5 months (2 to 6.5 months). There was no change in the elimination parameters of atenolol, but the maximal plasma atenolol concentration was increased (1.66 to 7.37 mg·l−1) as was the AUC (14.9 to 52.1 mg·l−1·h) when the hypothyroidism had been treated. Only one patient differed: he had had a supra-selective vagotomy, and had similar curves before and after treatment of the hypothyroidism, both being similar to the plasma concentration curves found in the other patients after correction of the hypothyroidism. The results suggest an increase in the bioavailability of atenolol when hypothyroidism is corrected. The findings in the patient with vagotomy suggest that the decreased bioavailability during hypothyroidism might be related to changes in intestinal pH. Further studies are needed of the impact of hypothyroidism on gastric and pancreatic or biliary function and its consequences for drug absorption, and drug pharmacokinetics.

    Mating strategies and mating success of fallow (Dama dama) bucks in a non-lekking population (1995)

    Notes: Abstract The rutting behaviour of bucks in an enclosed population was investigated between 1988 and 1990. A substantial proportion of the matings were observed. After preliminary observations in the 1987 rut we categorised bucks into one of four rutting strategies based mainly on their degree of territoriality. We investigate the effects of age, dominance and mating strategy on mating success. Territories were aggregated in an area of oak woods and mating success was highly skewed. Bucks of between 5 and 7 years old achieved the majority (over 90%) of observed matings. Mating success was highly correlated with dominance but only weakly related to fighting success. The possession of a territory was crucial to achieving high reproductive success, with a 38-fold difference between the most and least successful strategies. Bucks pursuing the different strategies also differed in the time they commenced groaning, timing of matings, mating interference and the locations where they achieved their matings. Although high-ranking males devoted considerable effort to obtaining and defending a territory only 36% of each buck's matings were achieved on his territory and males tended to abandon these sites when the tendency of females to visit them decreased.

    Elemental X-ray mapping of cementitious phases using an energy-dispersive spectrometer in the scanning electron microscope (1978)

    Notes: Elemental X-Ray mappings on Portland cement clinkers have been obtained using a scaning electron microscope-energy dispersive system (SEM-EDS). Using this method, elemental mapping of the major constituents of cement (Ca, Si, Al, Fe) can be generated in as little as 300 s, while the minor constituents(〈10%) Such as Na, Mg, P, S, K yield poorer contrast mappings. The technique used and the resultant mappings obtained are discussed.
