    Notes: A psychoanalyst is said to provide the real explanation of a person's behaviour; an explanation which the person has arrived at with the help of a psychoanalyst. The person was not aware of the real character of his behaviour. It may have exhibited unconscious thoughts, beliefs, motives, intentions and emotions. In his paper ‘The Unconscious’, in Mind 1959, Ilham Dilman says, ‘What those who talked of “Freud's discovery of the unconscious” had in mind is a group of innovations which “the founder of psycho-analysis” brought to bear on the study of the human mind’ (p.446). I have ten questions concerning the relation of this ‘group of innovations’ to human behaviour.

    Notes: Abstract Pachycrepoideus vindemiae Rondani (Hymenoptera: Pteromalidae) is a facultative hyperparasitoid ofDrosophila parasitoids in Europe. FemaleP. vindemiae host-feed from the same hosts into which they lay eggs and this enables them to mature additional eggs.P. vindemiae females were allowed to host-feed from puparia containingDrosophila melanogaster Meigen (Diptera: Drosophilidae) pupae or pupae ofAsobara tabida Nees (Hymenoptera: Braconidae). Wasps which had host-fed carried significantly more eggs; the species of host which was fed from had no significant effect on the number of mature eggs in the ovaries. Host-feeding caused no significant reduction in the size of the emerging offspring.P. vindemiae were allowed to forage over patches containing different frequencies of the two host species. No significant oviposition preference was found but there were marked host-feeding preferences which were affected by the age of the host pupae. It is suggested that these preferences were due to the physical nature of the hosts which were fed from.

    Notes: Summary Five sizes of canopy openings (0.016 ha to 10 ha) were established in the Southern Appalachian Mountains in early 1982 to examine the initial patterns of plant and arthropod establishment across a size range of forest disturbances. Vegetation standing crop after the first growing season was considerably higher in large than small openings in apparent response to greater resource release (e.g., sunlight) in larger openings. Woody stump and root sprouts were the dominant mode of revegetation in each patch size. Forest dominants such as Quercus rubra, Q. prinus and Carya spp. were less important as sprouters in openings than several minor forest components (e.g., Robinia pseudo-acacia, Acer rubrum, Halesia carolina and Cornus florida). Arthropod abundance and community composition varied across the size range of forest openings. Arthropods from the surrounding forest readily utilized the smallest canopy openings (0.016 ha). All feeding guilds were well represented in these small openings and herbivore biomass and load (mg of herbivores/g of foliage) were much higher than in larger patches. In contrast, arthropod abundance and species richness were significantly lower in mid-size than smaller patches. The relatively sparse cover and high sunlight in mid-size openings may have promoted surface heat buildups or soil surface/litter moisture deficits which restricted arthropod entry from the surrounding forest. Arthropod abundance and species richness were higher in large than mid-size patches. The greater vegetation cover in larger openings may have minimized the deleterious effects on arthropod populations. However, the absence of population increases among these arthropod species maintained herbivore loads at very low levels in large patches. Our results suggest that arthropod abundance and diversity in sprout-dominated forest openings are highly dependent on the extent of environmental differences between patch and surrounding forest.

    Notes: Abstract During the last several years, our TRAP collaboration has pioneered techniques for slowing, trapping, cooling and indefinitely storing antiprotons to energies more than 1010 times lower than previously possible. The radio signal from a single trapped antiproton is now being used for precision measurements. Many cold antiprotons are “stacked” as another important step toward the eventual production of antihydrogen, and positrons have been trapped in vacuum.

    Notes: Summary The present study examined the Liverpool database in an attempt to determine what proportion of N0 necks for various head and neck primary sites harbored subclinical squamous cell carcinoma and whether empiric treatment of occult disease improved survival over and above a “wait-and-watch policy” (treatment when metastasis becomes manifest). One hundred seventeen neck dissections were carried out for N0 necks, with 32% of specimens found to contain squamous cell carcinoma. The risk of carcinoma was highest in the hypopharynx, with 50% of specimens associated with a pyriform fossa primary cancer. Twenty-nine percent of neck dissection specimens for oral cavity cancer contained carcinoma and this was commonly associated with lateral border of tongue or anterior floor of mouth carcinomas. Twenty-five percent of specimens when primary tumor was in the oropharynx contained carcinoma and were due to tonsillar carcinoma. Twenty-one percent of laryngeal cancers produced histologically positive nodes and were mostly associated with posterior epiglottic tumors. Two hundred forty-six patients had a pyriform fossa cancer and of these only 37 had N0 disease and surgical treatment. Of these, 23 patients had radical neck dissections, whereas in 14 the necks were not treated. There was no difference in survival between the two groups (ξ1 2 = 0.787, P = NS). The Liverpool database also contained 1631 previously untreated patients with no clinical evidence of neck node metastases. Of these only 107 had a neck dissection. There was no difference in survival (ξ1 2 = 2.79, P = NS). When these data were analyzed by multivariate methods (Cox's proportional hazards model) prophylactic neck dissection was found to have no significant effect.

    Notes: Abstract The EPIC model was used to simulate soil erosion and soil C content at 100 randomly selected sites in the US corn belt. Four management scenarios were run for 100 years: (1) current mix of tillage practices maintained; (2) current trend of conversion to mulch-till and no-till maintained; (3) trend to increased no-till; (4) trend to increased no-till with addition of winter wheat cover crop. As expected, the three alternative scenarios resulted in substantial decreases in soil erosion compared to the current mix of tillage practices. C content of the top 15 cm of soil increased for the alternative scenarios, while remaining approximately constant for the current tillage mix. However, total soil C to a depth of 1 m from the original surface decreased for all scenarios except for the no-till plus winter wheat cover crop scenario. Extrapolated to the entire US corn belt, the model results suggest that, under the current mix of tillage practices, soils used for corn and/or soybean production will lose 3.2 × 106 tons of C per year for the next 100 years. About 21% of this loss will be C transported off-site by soil erosion; an unknown fraction of this C will be released to the atmosphere. For the base trend and increased no-till trend, these soils are projected to lose 2.2 × 106 t-C yr−1 and 1.0 × 106 t-C yr−1, respectively. Under the increased no-till plus cover crop scenario, these soils become a small sink of 0.1 × 106 t-C yr−1. Thus, a shift from current tillage practices to widespread use of no-till plus winter cover could conserve and sequester a total of 3.3 × 106 t-C yr−1 in the soil for the next 100 years.
