Fachkatalog Neuguinea / Stadt- und Universitätsbibliothek Frankfurt am Main
No full textAus Anlaß des Kongresses der "Deutsch-Pazifischen Gesellschaft" im Juni 1981 in Düsseldorf legt die Stadt- und Universitätsbibliothek Frankfuxt am Main ein Verzeichnis ihrer Bestände zum Raum "Neuguinea" vor . Dabei umfaßt der Katalog sowohl die Literatur zu "Papua-Neuguinea" (Niugini)" als auch zur indonesischen Provinz "West-Irian (Irian Jaya)". Aus Gründen des geographischen Zusammenhangs werden in einem Anhang allgemeine Publikationen zum Raum Melanesien in den Katalog aufgenommen. Die gezielte Sammlung der Literatur zu diesem Raum ist ein Ergebnis der Zuweisung des Sondersarnmelgebietes "Ozeanian" durch die Deutsche Forschungagemeinschaft an die Frankfurter Stadt- und Univeraitätsbibliothek. Dabei liegt der Schwerpunkt auf der Sammlung historischer und ethnologischer Literatur. Grundlage des Katalogausdruckes ist der Länderteil des Sachkataloges der Bibliothek, der nach feststehenden Länderkennziffern, Fachgruppen und Schlüsselnummern gegliedert ist. Unter jeder Schlüsselnummer sind die Eintragungen chronologisch geordnet. Auf jeder Titelkarte befindet sich rechts oben die Signatur, unter der das Buch über Fernleihe bei der Stadt- und Universitätsbibliothek Frankfurt am Main bestellt werden kann
Correlation of microseismic and chemical properties of brittle deformation in Locharbriggs sandstone
No full textThe time-dependent properties of ceramic materials such as rocks depend both on preexisting cracks and chemical properties acting at their tips. We have examined the direct effect of chemical processes on the growth of a crack population by carrying out triaxial flow-through compression tests on Locharbriggs sandstone. The tests were carried out at temperatures of 25–80°C and at strain rates ranging from 10−5 to 10−8 s−1 under constant stress rate loading. The exit pore fluid was analyzed after the tests for the concentration of dissolved ions and acoustic emission was monitored in real time throughout the tests. The exit pore fluid silica concentration and microcrack damage derived from the acoustic emission (AE) data both exhibited an exponential increase during the strain hardening phase of deformation. Damage parameters inferred from the AE data predict the stress-strain curves adequately, or at least up to the point of strong microcrack coalescence. The damage parameters and silica signal were strongly correlated by a power law relationship. The observed environment and strain rate dependence of mechanical properties can hence be attributed uniquely to time-dependent crack growth by the stress corrosion mechanism
Treatment of Chronic Viral Hepatitis
No full textSignificant advances have been made in the treatment of both hepatitis B and C. Cure for the majority is becoming reality. Combination regimens are now established therapy in hepatitis C and the near future will see the adoption of a similar approach to hepatitis B. Interferon alpha therapy remains important, with the development of more efficacious pegylated forms. In this article we review current therapy and discuss future strategies of the therapy for chronic viral hepatitis.</p
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

Electrical and optical properties of self-assembled quantum dots
No full textOne of the main directions of contemporary semiconductor physics is the production and study of structures with a dimension less than two, i.e. quantum wires (QWi) and quantum dots (QDs), in order to realise novel devices that make use of low-dimensional confinement effects. One of the promising fabrication methods is to use self-organised three-dimensional (3D) structures, such as 3D coherent islands, which are often formed during the initial stage of heteroepitaxial growth in lattice-mismatched systems, Quantum dots, for example, are believed to provide a promising way for a new generation of optical light sources such as injection lasers. While quantum well structures are already widely used in optoelectronic devices, QWi and QDs appear to be much more difficult to fabricate for this purpose. Some of the electrical and optical properties of self-assembled QDs will be reported in this paper. (C) 2002 Published by Elsevier Science Ltd
Treatment of histologically mild hepatitis C virus infection with interferon and ribavirin: a multicentre randomized controlled trial
No full textCurrent guidelines advocate no treatment for patients with histologically mild hepatitis C virus (HCV) infection. This was a UK multicentre randomized controlled trial comparing alpha-interferon (3 MU thrice weekly) + ribavirin (1000-1200 mg/day) for 48 weeks with no treatment in treatment naive, adult patients with histologically mild chronic HCV infection. The aim was to compare benefits, safety and efficacy of combination therapy with alpha-interferon 2b and ribavirin for 48 weeks with no treatment (current standard management) in this patient group. In the treatment group 32 of 98 (33%) patients achieved a sustained virological response (SVR). Patients infected with genotype 1 had a lower SVR than those infected with genotype non-1 (18% vs 49% P = 0.02). No patients who failed to achieve a 2-log drop in viral load at 12 weeks achieved SVR. Improvements in quality of life 24 weeks postcessation of therapy compared with baseline using the SF-36 questionnaire measures were observed in the treated group. For patients with mild HCV infection with viral genotype non-1, the results are sufficiently good to suggest that therapeutic decisions should no longer be biopsy-driven. For patients infected with genotype 1, a liver biopsy is still indicated as the low chance of SVR is outweighed by an unacceptable burden of side-effects. Patients who fail to respond by 12 weeks of therapy should have their treatment curtailed early.</p
