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

Ra-partitioning between phlogopite and silicate melt and ^(226)Ra/Ba–^(230)Th/Ba isochrons
No full textIn this study we experimentally determine phlogopite/melt partition coefficients of Ra and other trace elements in a lamproitic system. This work was achieved using an analytical technique (LA-ICP-MS) with low detection limits (~0.01 fg) permitting the measurement of the very low Ra concentrations feasible in experiments (~1 ppb). D_(Ra)^(phlogopite/melt) was determined to 2.28 ± 0.44 and 2.84 ± 0.47 in two experiments, the ratio D_(Ra)/D_(Ba) is around 1.6. The compatibility of Ra in phlogopite results from an ionic radius being close to the apex of the lattice strain parabola for earth alkalis in the large XII-coordinated interlayer site of phlogopite. A re-evaluation of D_(Ra) and D_(Ra)/D_(Ba) for magmatic minerals containing appreciable Ra, yields D_(Ra)^(mineral/melt) ranging from ~2.6 for phlogopite down to 2–3 • 10^(−5) for pyroxenes, and D_(Ra)/D_(Ba)^(mineral/melt) from ~4 for leucite to 2 • 10^(−2) for orthopyroxene. The influence of melt composition on D_(Ra)/D_(Ba) is less than 10%. All investigated minerals have different D_(Ra)/D_(Ba), strongly fractionating Ra from Ba. Thus, for magmatic systems, (^(226)Ra)/Ba in the various minerals is not constant, these minerals do not form a straight line in the (^(226)Ra)/Ba–(^(230)Th)/Ba system at the time of crystallization and thus, there is no (^(226)Ra)/Ba–(^(230)Th)/Ba isochron at t_0. 226Ra–230Th–Ba mineral dating is thus applicable only to model ages calculated from mineral–glass pairs with known D_(Ra)
Rayleigh number dependence of the Archimedes number dependent large-scale flow structure formation in mixed convection
No full textWe report on experimental investigations of large-scale flow structure formation in mixed convection. We characterize the flow field by measuring the velocity fields within a rectangular model room using 2D2C PIV. The control parameters are the Reynolds number Re, the Rayleigh number Ra and the Prandtl number Pr. All parameters are linked through the Archimedes number Ar. In 6.4x10-2 ≤ Ar ≤ 1.39x101, 4.2x103 ≤ Re ≤ 6.35x104 and Ra = 3.1x107, Ra = 1.8x108 and Pr = 0.713 we found flow 3 different flow structures. While keeping Ra and Pr constant and varying Ar through Re variations, we found an Ar dependence of the largescale flow structure formation within 6.4x10-2 ≤ Ar ≤ 1.39x101. Furthermore, we found a Ra dependence of the structure formation, which shifts the transition points between the structures to higher Archimedes numbers and reduces the mean velocities within the investigated domain
Clinical and endocrine characteristics of the main polycystic ovary syndrome phenotypes
No full textAbstract
OBJECTIVE:
To evaluate the clinical and endocrine differences between main polycystic ovary syndrome (PCOS) phenotypes.
DESIGN:
To evaluate clinical and hormone parameters in a large group of consecutive women with PCOS diagnosed according Rotterdam criteria and divided according their phenotype.
SETTING:
University department of medicine.
PATIENT(S):
Three hundred eighty-two consecutive women with PCOS and 85 ovulatory controls.
INTERVENTION(S):
Evaluation of clinical and hormone parameters.
MAIN OUTCOME MEASURE(S):
Blood levels of gonadotropins, testosterone, sex-hormone-binding globulin, dehydroepiandrosterone sulfate, 17α-hydroxyprogesterone, progesterone, glucose, and insulin, and calculation of the free androgen index and insulin sensitivity.
RESULT(S):
The severe PCOS phenotype (hyperandrogenism, chronic anovulation, and polycystic ovaries: type I classic PCOS) was the most common phenotype in 53.9% of the patients. The phenotype of 8.9% of patients was characterized by hyperandrogenism and chronic anovulation but normal ovaries (type II classic PCOS). The two phenotypes of classic PCOS had similar clinical and endocrine characteristics, but the patients with polycystic ovaries had a higher luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio. Ovulatory PCOS was relatively common (28.8% of PCOS patients) and presented milder clinical and endocrine alterations than the classic PCOS phenotypes. The normoandrogenic phenotype was relatively uncommon. These patients had a normal body mass index, insulin sensitivity, and free androgen index but showed increased levels of LH and LH/FSH ratio.
CONCLUSION(S):
Ovulatory PCOS represents the mild form of classic PCOS, but the normoandrogenic phenotype, although part of the spectrum, may represent a different disorder or have a different pathogenetic pathway.

Reynolds numbers near the ultimate state of turbulent Rayleigh-Bénard convection
No full textWe report on measurements of the mean-flow Reynolds number ReU and the rms fluctuation Reynolds number ReV in turbulent Rayleigh-Bénard convection as a function of the Rayleigh number Ra for 4 x 1011 < Ra < 2 1014 and Pr ' 0:8. Both can be described by the same power law with an effective exponent = 0:44, in agreement with predictions for ReU but in disagreement with predictions for ReV
