Molecular line emissions from pre main sequence objects [PDF]

open access: yes, 1997
We present some preliminary results obtained with the LWS G.T. programme on the study of young objects driving molecular outflows. In particular, we discuss the importance of molecular emission in these sources and address the role of the H20 ...

Assessment of upper tropospheric HOx sources over the tropical Pacific based on NASA GTE/PEM data: Net effect on HOx and other photochemical parameters [PDF]

open access: yes, 1999
Data for the tropical upper troposphere (8-12 km, 20° N-20° S) collected during NASA's Pacific Exploratory Missions have been used to carry out a detailed examination of the photochemical processes controlling HOx (OH+HO2).

Effect of CuO-H20 and ZnO-H20 nanofluids on the Performance of Solar Flat Plate Collector

open access: yesInternational Journal of Advanced Thermofluid Research, 2019
The solar flat plate collector is commonly used in low-temperature domestic applications for water heating. In this paper, copper oxide (CuO) and zinc oxide (ZnO) nanofluids were synthesized and prepared with water as base fluid, and its thermal efficiency is examined by conducting experiment on a solar flat plate collector.

Solubilidad del bióxido de carbono en agua en condiciones geotérmicas

open access: yesGeofísica Internacional, 1992
Las correlaciones de solubilidad del sistema H20-C02 aplicadas hasta el presente en la simulación numerica de flujos en yacimientos y pozos geotermicos no son cuantitativamente confiables.

Hawaii Two-0: High-redshift galaxy clustering and bias [PDF]

open access: yes, 2019
We perform an analysis of two-point galaxy clustering and galaxy bias using Subaru Hyper-Suprime Cam (HSC) data taken jointly by the Subaru Strategic Program and the University of Hawaii in the COSMOS field. The depth of the data is similar to the ongoing Hawaii Two-0 (H20) optical galaxy survey, thus the results are indicative of future constraints ...

Dissipative structures of diffuse molecular gas: I - Broad HCO$^+$(1-0) emission [PDF]

open access: yes, 2006
Results: We report the detection of broad HCO+(1-0) lines (10 mK < T < 0.5 K). The interpretation of 10 of the HCO+ velocity components is conducted in conjunction with that of the associated optically thin 13CO emission. The derived HCO+ column densities span a broad range, $10^{11}< N(HCO+)/\Delta v <4 \times 10^{12} \rm cm^2/(km/s^{-1}$, and the ...

The Warm Molecular Gas Around the Cloverleaf Quasar [PDF]

open access: yes, 2009
We present the first broadband lambda = 1 mm spectrum toward the z=2.56 Cloverleaf Quasar, obtained with Z-Spec, a 1-mm grating spectrograph on the 10.4-meter Caltech Submillimeter Observatory. The 190-305 GHz observation band corresponds to rest-frame 272 to 444 microns, and we measure the dust continuum as well as all four transitions of carbon ...
