Action du laser C02 sur le spectre d'absorption infrarouge du C02
Bulletin de la Classe des sciences, 1973Le travail met en évidence l'effet d'un laser C02 sur le spectre d'absorption de ce même gaz dans la région de 15 fi. On étudie plus spécialement le comportement des raies d'absorption sous l'effet d'un rayonnement laser régulièrement interrompu.

Experimental determination of vapor-liquid equilibria of C02 + limonene and C02 + citral mixtures
The Journal of Supercritical Fluids, 1995Abstract By using an infrared absorption method together with a synthetic method, experimental results on the phase behavior of CO 2 -limonene and CO 2 -citral binaries have been obtained. Experiments were performed in the temperature range 310–323 K and in the pressure range 7–10 MPa for the CO 2 -limonene mixture and from 310 to 330 K in the ...

Die C02-Laserexzision oraler Präkanzerosen
1995In einem Zeitraum von drei Jahren wurden an unserer Klinik 95 Prakanzerosen der Mundschleimhaut mit dem C02-Laser in fokussierter Einstellung bei Leistungen von 3–5 Watt exzidiert. Alle Exzisate konnten pathohistologisch aufgearbeitet werden. Die Wunden wurden der freien Granulation und der sekundaren Epithelisation uberlassen.

A C02 Controller for Greenhouses
Transactions of the ASAE, 1979ABSTRACT AC02 controller for greenhouses was designed and experiments were conducted to determine its capa-bility to control C02 enrichment under the changeable weather of the southeastern United States. The inex-pensive solid-state controller was designed to turn on a natural-gas C02 generator when solar radiation was above the setpoint of 14 W/m2 and

C02 and climate: a missing feedback?
Nature, 1989THE potential of changes in cloud properties to modulate climate perturbations is well known1,2. Changes in cloud amount and cloud height3, cloud radiative properties4–6 and cloud condensation nuclei7 (CCN) have all been recognized as possible sources of climate feedbacks. Here we report results of simulations that indicate that the changes of state of

Atmospheric C02 Concentration in Subantarctic Countries
1986The atmospheric C02 concentrations at Amsterdam Island (37° 41’S; 77°, 47’E) showed three kinds of variations from October 1980 to November 1983. The first one, attributed to local effects of the photosynthesis of the island vegetation, does not seem considerably to affect the monthly mean C02 concentrations.

EPA HAS DENIED A 1999 PETItion from environmental groups asking the agency to regulate carbon dioxide from motor vehicles under the Clean Air Act. The agency provides two primary reasons for its Aug. 28 decision: The Clean Air Act does not give EPA authority to regulate CO 2 for climate-change purposes, and setting up emissions standards for motor ...
