    Notizen: This paper traces the process of the decline of African middlemen in Eastern Nigeria from wealthy entrepreneurs of the late nineteenth century to petty traders after 1930. Four phases are identified in their decline. During the first phase, 1900–5, the middlemen lost only the political control of their trading areas but benefited commercially. The establishment of colonial rule expanded their market. And with the reluctance of expatriate firms to move into the interior, the continued ignorance of the natives of the actual prices of their produce and of imported goods, and the encouragement from the colonial administrators, African middlemen prospered.These advantages were lost during the second phase, 1905–16. As the firms began to move inland from 1905, they traded with the natives and fostered a new group of smaller and dependent middlemen. The middlemen's market began to contract and their wealth declined. Their fortunes worsened during the third phase, 1916–30. With the opening of the Eastern Railway to traffic in 1916 and the increased construction of roads during this period, the firms intensified their penetration of the interior, swallowing up what remained of the middlemen's market. The introduction of produce inspection in Eastern Nigeria in 1928 added more hardships for the middlemen, putting many out of business. And by 1930 the trust system, upon which most middlemen depended after 1916 for raising their trading capital, collapsed, leaving most of them impoverished.Thus, after 1930 African middlemen were no more than petty traders, trading with little capital and making marginal profit. They became incapable of challenging the expatriate firms in the import–export trade as their predecessors had done in the nineteenth century. The firms employed various trade malpractices to ensure that the African traders retained this status until the 1940s.

    Notizen: Abstract The total photofission cross section σγ,F for235U and238U has been measured in the energy range 50≤E γ≤800 MeV at the 855 MeV Mainz Microtron MAMI using energy and time tagged photons (Glasgow Tagger) and a 4π arrangement of position sensitive fragment detectors. Besides the absolute photofission cross section σγF , which almost completely exhausts the total photon absorption cross section for these nuclei, fragment mass distributions in this energy domain were determined via time of flight techniques (TOF). The results for the total photofission cross sections σγ,F normalized to the atomic numberA for both isotopes coincide, and agree in theΔ-resonance region, within the systematic errors, with the socalled“Universal Curve” σγ,T /A of the total photon absorption cross section σγ,T . At higher energies the cross sections exhibit a smooth behaviour. In particular, it is shown for the first time that there isno resonance-like shape near the D13 resonance (at ≈710 MeV) as observed for the free proton. This complete suppression of the D13 resonance in complex nuclei is not yet understood on a microscopic level. The fragment mass distributions show a predominantly mass symmetric fission. However, contributions from mass asymmetric fission at some photon energies may give a hint of an increased mass asymmetric fission after the onset of the pion and two pion channels.

    Notizen: Abstract Twoin vivo methods that permit quantitation of gastric acid secretion immediately after the meal are currently in use: intragastric titration and the serial dilution indicator method. During intragastric titration, intragastric pH is artifically maintained at 5.5 to 7 by the continuous addition of alkali to the gastric contents, while during serial dilution the intragastric pH is permitted to seek its natural pH. This study compared gastric acid secretion and serum gastrin in response to a liquid protein meal measured by both techniques in 10 subjects. Mean (±se) 3-hr acid outputs were almost identical (53.6±6.0 mmol/3 hr with intragastric titration and 52.0±8.5 mmol/3 hr with serial dilution indicator). Furthermore, 30 min secretory responses in individual subjects were highly correlated (r=0.98±0.01, P〈0.001). Also, in spite of intragastric pH being less than 1.5 by 90 min after the meal during the serial dilution method, total integrated serum gastrin concentrations after the meal were similar (intragastric titration=20.6±7.3 ng min/ml versus serial dilution indicator=23.5±9.8 ng min/ml) and individual 30-min gastrins during the two separate tests were highly correlated (r=0.80±0.06, P〈0.01). It is concluded that both meal-stimulated gastric acid secretion and serum gastrin concentrations as measured by intragastric titration and by the serial dilution indicator method produced similar results.

    Notizen: Abstract The pancreatic polypeptide (PP) response to a protein-rich meal has been studied in similarly aged patients with gastric ulcer, duodenal ulcer, and controls. The response of the gastric ulcer patients was significantly lower at all points than that of the duodenal ulcer patients or controls, which were similar to one another. Vagal stimulation is probably the single most important factor in PP release, and it is possible that diminished PP release in the gastric ulcer patients is a reflection of vagal underactivity.

    Notizen: Abstract The pancreatic polypeptide (PP) response to food has been measured by radioimmunoassay in patients with duodenal ulcer and 3 months following proximal gastric vagotomy (PGV), 18 and 49 months following truncal vagotomy and pyloroplasty (TV), 35 months following Billroth II gastrectomy (BII), and 35 months following truncal vagotomy and antrectomy (TV&A). Basal PP levels and those in response to food were similar in DU and PGV, but these values were significantly higher than those 18 months or 49 months after TV, or after BII and TV&A. The responses in the latter four groups were similar and in particular, the levels 18 and 49 months after TV were the same. These results indicate that the release of PP by food in unoperated patients consists of two phases, a primary phase which requires both intact vagi and an intact stomach and a secondary phase which also depends on vagal innervation and normal gastric anatomy. Disturbances in vagal innervation or gastric integrity lead to profound changes in PP release which may be due to interruption of neural arcs or loss of gastric hormones. Unlike others, we have been unable to document a return of PP secretion towards normality with time after TV.
