    Notes: Preliminary experiments were conducted to assess the winter hardiness of representative cultivars or populations of Festuca rubra, Holcus lanatus and Agrostis spp. in comparison with a hardy (Premo) and a susceptible (Grasslands Ruanui) cultivar of Lolium perenne. Two controlled-environment tests and a field experiment including two cutting and two fertilizer managements are reported.Grasslands Ruanui andH lanatus suffered most damage in all tests. In the controlled-environment experiments, Premo was at least as hardy as the F. rubra and Agrostis cultivars but in the field Premo was more susceptible. Spring growth of Premo was affected more by the cutting and fertilizer managements applied the previous summer and autumn than was spring growth of F. rubra or Agrostis spp.It was concluded that, whereas use off. F. rubra or Agrostis spp. should not be limited by fears of winter damage, poor winter hardiness may limit the value of H. lanatus for hill and upland reseeding.

    Notes: In this article the author, using case study material, considers the motives which induce individuals either to join associations or to free-ride. In particular, he concludes that analysis and thinking on the free-rider problem needs to be pursued in a specific, well defined manner.

    Patterns of tooth vulnerability to caries in South African high school pupils (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Details

    Topics: Medicine
    Notes: Caries prevalence and distributions were studied in 761 South African high school pupils aged 17 years in four ethnic groups, living in urban (low F) and rural (low and high F) areas. Mean DMFT values were significantly higher among White pupils than all other groups. Comparison of mean DMFT among the Black pupils showed that urban Black dwellers had a significantly higher score than rural pupils when caries-free individuals were included in the analysis, but not when scores for only those with a DMFT of 1 or more were compared. No significant differences were found between the DMFT values of Black rural pupils living in high or low fluoride areas. Among Black rural pupils, dental caries was approximately three times more common in permanent second molars compared with permanent first molars. In urbanized Black, Coloured, Indian and White subjects, the molars were approximately equally affected.

    Primary dentition caries trends, 1976–1981, in four South African populations (1983)

    Notes: Abstract— This paper is a comparison of cross-sectional data on dental caries in the primary dentition undertaken between 1976 and 1981 in the Transvaal Province, South Africa, on 690 rural Black, 1463 urban Black, 870 Indian and 1622 White children aged 2–5 yr. There was a decrease in percentage dental caries prevalence in the urban White children and an increase in the other three groups, the fastest rate being seen among urban Indian children. Similar trends were noted for mean dmft. Dental caries in incisor and canine teeth remained fairly static but caries in molar teeth increased in the groups of Black and Indian children and decreased in the White children. Ratios d/dmft, m/dmft and f/dmft indicated that minimal treatment was received by all the children.

    Dental caries, gingival health and malocclusion in 12-year-old urban Black schoolchildren from Soweto, Johannesburg (1981)

    Notes: Abstract The oral health of 402 12-year-old Black schoolchildren was studied. Dental caries was seen in 65.6%, but 58.2% had a DMFT of less than 6, while the mean DMFT was 2.3. Few teeth were missing or filled, the majority being decayed. No significant association was found between DMFT and sex, ethnic group or father's occupation. Periodontal disease was seen in 40.3% and malocclusions were rare, being present in only 11.1%.

    Dental caries in rural and urban black preschoolchildren (1978)

    Notes: abstract The dentitions of 439 rural and 192 urban black children aged 1–5 years were examined with mirror and probe. Denial caries was common and the percentage prevalence and dmft values were similar in children of 1–3 years in both groups. At 4 years of age there was a twofold increase in dental caries in the urban children to reach a dm ft score significantly greater than that in the rural children (P〈0.01). Labial caries was common in rural children but rare in urban children while rampant caries (dmft ≥5) exhibited the opposite pattern.

    Notes: Nitrous oxide concentrations (V/V) at the delivery Rotameters block, nasal mask, pharynx and venous blood, were compared. There was a dilution of approximately 50% of the delivered nitrous oxide at the nasal mask which was further reduced in the pharynx. Venous blood concentrations 10 minutes after inhalation of nitrous oxide were low but as would be calculated from pharyngeal concentrations. After 5 minutes of oxygenation venous blood nitrous oxide concentrations were still relatively high. A total of 92% of subjects experienced a satisfactory effect with 30% nitrous oxide or less in the pharynx.

    Effects of intermittent 0.5% nitrous oxide/air (v/v) on the fertility of male rats and the post-natal growth of their offspring (1983)

    Notes: In a study of male rat fertility male Wistar albino rats were exposed to 0.5% nitrous oxide/air mixtures (v/v) for 30 days and control rats were exposed to oil-free air for the same time period. Thereafter each male was mated with three nulliparous female rats and mated again with three more nulliparous rats after a 6-month recovery period. The offspring were weighed and measured for 8 weeks postnatally. There was a significant reduction in mean litter size of the female rats mated with the male rats directly after the nitrous oxide exposure period. The offspring from the female rats mated with the males directly after the exposure period were significantly smaller in size than the control group. These results show a reversible reduction in male Wistar rat fertility, after exposure to 0.5% nitrous oxide in air (v/v), as well as a postnatal growth depression.
