Thermal conductivity of gaseous and liquid hydrogen

Normal and para-hydrogen conductivity measurements at temperatures from 200 to 17 deg K, at densities up to 2.6 times critical density, and at pressures to 15 MN/sq m are made. Using new calorimeter, data are analyzed as functions of density at fixed temperatures and of temperature at fixed densitie

Computer programs for thermodynamic and transport properties of hydrogen

Computer program subroutines provide the thermodynamic and transport properties of hydrogen in tabular form. The programs provide 18 combinations of input and output variables. This program is written in FORTRAN 4 for use on the IBM 7044 or CDC 3600 computers

Effektivität des Integrierten Psychologischen Therapieprogramms für schizophren Erkrankte: Eine Metaanalyse über 28 unabhängige Studien

Zusammenfassung: Während der letzten 24Jahre führten Arbeitsgruppen aus 8Ländern 28 unabhängige Evaluationsstudien zum Integrierten Psychologischen Therapieprogramm (IPT) mit insgesamt 1329 schizophren Erkrankten durch. Zur Überprüfung der Wirksamkeit des IPT unter verschiedenen Versorgungsbedingungen wurden die inferenzstatistischen Ergebnisse sämtlicher Studien in Effektstärken transformiert. Die IPT-Gruppen zeigen einen signifikant höheren mittleren Therapieeffekt gegenüber den Kontrollgruppen (Plazebo-Attention-Bedingungen; Standardbehandlung). Die Überlegenheit der IPT-Gruppen nimmt im Verlauf einer durchschnittlichen Katamnesedauer von 8,1 Monaten weiter zu. Vergleichbar hohe Effekte lassen sich für die IPT-Gruppen sowohl in verschiedenen Funktionsbereichen (kognitive Fähigkeiten, Sozialverhalten, Psychopathologie) als auch mit unterschiedlichen Erhebungsformaten (psychologische Tests, standardisierte Selbst- und Fremdratings) nachweisen. Die Ergebnisse belegen weiter, dass Patienten unabhängig von Krankheits-, Rehabilitationsstatus und Therapiesetting vom IPT profitieren. Alle Ergebnisse sind mittels einer Selektion von qualitativ hochstehenden Studien validiert. Zusammenfassend unterstützen damit die Ergebnisse die Evidenz des IPT als einen "empirisch validierten Treatmentansatz" im Sinne der APA-Richtlinie

Uniform data system standardizes technical computations and the purchasing of commercially important gases

Integrated tables of pressure, volume, and temperature for the saturated liquid, from the triple point to the critical point of the gases, have been developed. Tables include definition of saturated liquid curve. Values are presented in metric and practical units. Advantages of the new tables are discussed

Transport Properties of the One Dimensional Ferromagnetic Kondo Lattice Model : A Qualitative Approach to Oxide Manganites

The transport properties of the ferromagnetic Kondo lattice model in one dimension are studied via bosonization methods. The antiferromagnetic fluctuations, which normally appear because of the RKKY interactions, are explicitly taken into account as a direct exchange between the ``core'' spins. It is shown that in the paramagnetic regime with the local antiferromagnetic fluctuations, the resistivity decays exponentially as the temperature increases while in the ferromagnetic regime the system is an almost perfect conductor. %A non-perturbative description of localized spin polarons %in the paramagnetic region is obtained. The effect of a weak applied field is discussed to be reduced to the case of the ferromagnetic state leading to band splitting. The qualitative relevance of the results for the problem of the Oxide Manganites is emphasized.Comment: 4 pages, REVTe

This study assesses the physical and biochemical characteristics of an eastern boundary current (EBC) and recurrent eddies in the central Red Sea (CRS) using a combination of in situ and satellite observations. Hydrographic surveys in November 2013 (autumn) and in April 2014 (spring) in the CRS (22.15°N–24.1°N) included a total of 39 and 27 CTD stations, respectively. In addition, high-resolution hydrographic data were acquired in spring 2014 with a towed undulating vehicle (ScanFish). In situ measurements of salinity, temperature, chlorophyll fluorescence, colored dissolved organic matter (CDOM), and dissolved nitrate: phosphorous ratios reveal distinct water mass characteristics for the two periods. An EBC, observed in the upper 150 m of the water column during autumn, transported low-salinity and warm water from the south toward the CRS. Patches of the low-salinity water of southern origin tended to contain relatively high concentrations of chlorophyll and CDOM. The prominent dynamic feature observed in spring was a cyclonic/anticyclonic eddy pair. The cyclonic eddy was responsible for an upward nutrient flux into the euphotic zone. Higher chlorophyll and CDOM concentrations, and concomitant lower nitrate:phosphorous ratios indicate the influence of the EBC in the CRS at the end of the stratified summer period.King Abdullah University of Science and Technology (KAUST); Core Marine Operation Research Lab (CMOR
