Published 1994Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: ac magnetic susceptibility measurements is one of the processes by which the superconducting properties of mixed oxide superconductors can be characterized. The study of the superconductors at an externally applied magnetic field predicts the existence of two superconducting transitions due to: (i) the one reflecting the intragrain properties and (ii) the other describing intergrain interactions which might be assumed as due to Josephson tunneling. In this abstract, we report our work on the ac susceptibility measurements in PbxBi2−xSr2Ca2Cu3O10 superconductors to study the real part of χ' as a function of temperature, Pb concentration, and sintering time. The results have been compared with the x-ray diffraction (XRD) results. The material preparation and the characterization techniques used would be discussed. The XRD and the susceptibility measurements indicate that too high Pb concentrations and too low sintering time does not seem to improve the high Tc phase. The weak link coupling phase determined from the χ'-T dependence is strongly dependent on both the Pb concentration and the sintering time. The transition temperature for the low Tc phase decreases with sintering time and increases with the increasing Pb concentration. The results would be discussed in the light of the best superconducting properties achieved by variation of the material preparation.Type of Medium: Electronic ResourceURL: -

Published 1976Staff ViewISSN: 1365-3180Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: In a field experiment on an organic soil, a pre-emergence application of paraquat at 2–24 kg a.i. (active ingredient)/ha was made to a plot on which onions and lettuce were grown; and similar broadcast applications of linuron, both with and without carbofuran, at two field rates, to plots on which carrots were grown. Paraquat generally increased the bacterial and actinomycetal populations while linuron inhibited the same but enhanced the numbers of fungal propagules, although it decreased the proportion of soil penicillia in the population. The overall effect of linuron was not changed by the admixture of carbofuran. However, the changes in microbial populations by either herbicides were not substantial enough to make gross or lasting differences in levels of available N and P, and in the CO2 evolution rate.Type of Medium: Electronic ResourceURL: -

ISSN: 1399-3054Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Effects of uracil, thymine and their analogues, 5-nitrouracil, 2-thiouracil, 6-azauracil, and 6-azathymine on nodulation in Sesbania aculeata have been studied. The seeds were dipped partially in a 15 ml solution of each of different concentrations. The experiments included treatments for 6 or 12 h with distilled water as control. The treated seeds were inoculated with a pure culture of Rhizobium leguminosarum and sown in sand cultures, weekly supplied with modified White's basic N-free solution.Nodulation in Sesbania aculeata was promoted by uracil, nitrouracil and thymine, but inhibited by analogues. Higher concentrations caused greater inhibition than lower ones. Nodulation was affected by changes in the nucleic acid and protein metabolisms.Type of Medium: Electronic ResourceURL: -

ISSN: 1399-3054Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: The effects of uracil and its analogue 5-nitrouracil on growth and flowering of tomato have been studied. A few drops (0.3 ml) of solutions containing 15, 30, 60, 90 and 150 μg of each prepared from a stock of 500 mg/I in glass redistilled water were applied per plant on 3–4 top leaves and the apex of one month old seedlings with 6–7 leaves. A second application double in volume of the same chemicals was made on the same plants a week later. The controls were given a distilled water treatment.Treatments with uracil and 5-nitrouracil significantly increased the plant height and the fresh and dry weights of the shoot. Higher concentrations (500 mg/I) had no promotive effect. Although there had been a significant promotion of the leaf and stem growth, the root growth and the nodes were unaffected.Flowering was significantly hastened by both bases. Treatments with uracil also resulted in the formation of more flowers. Uracil and 5-nitrouracil also caused significant increases in the total-N of the leaf and the stem, and the effect on protein metabolism seems to be localised where they act as RNA metabolites. The presence of the nitro-group in 5-nitrouracil does not act as an additional source of nitrogen for protein metabolism as it did not have more promotive effects than uracil.Type of Medium: Electronic ResourceURL: -

Published 2005Staff ViewISSN: 1365-2036Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background : Barrett's oesophagus patients may continue to have abnormal oesophageal acid exposure on proton pump inhibitor therapy. The effect of factors such as Barrett's oesophagus length, hiatal hernia size and Helicobacter pylori infection on intra-oesophageal pH in Barrett's oesophagus patients has not been adequately studied.Aim : To evaluate oesophageal acid exposure in a large Barrett's oesophagus population on b.d. proton pump inhibitor therapy and determine clinical factors predicting normalization of intra-oesophageal pH on therapy.Methods : Barrett's oesophagus patients were studied using 24 h pH monitoring to evaluate intra-oesophageal acid suppression on b.d. dosing of rabeprazole.Results : Forty-six Barrett's oesophagus patients completed the study. Median total percentage time pH 〈 4 was 1.05% (range: 0–29.9%) in the entire group and respective values for upright and supine percentage time pH 〈 4 were 1.15% and 0%. However, 34 of the Barrett's oesophagus patients (73.9%) had a normal pH study (median total percentage time pH 〈 4: 0.2%) and 12 patients (26.1%) had an abnormal result (median total percentage time pH 〈 4: 9.3%). There were no significant differences between patients with a normal and abnormal 24 h pH result with respect to age, Barrett's oesophagus length, hiatal hernia size and presence of H. pylori infection.Conclusions : Approximately 25% of Barrett's oesophagus patients continue to have abnormal total intra-oesophageal pH profiles despite b.d. proton pump inhibitor therapy. Factors such as age, Barrett's oesophagus length and hiatal hernia size cannot be used to predict persistent abnormal intra-oesophageal pH on proton pump inhibitor.Type of Medium: Electronic ResourceURL: -
