The FN method is used to establish numerical results basic to polarization studies in plane parallel atmospheres.

T he discovery was based on an analysis of anomalies in the periodicity of the pulsar radio signal. Three years later, M. Mayor and D. Quéloz reported the first detection of an exoplanet around a solar-type star, 51 Peg. The method used this time was the so-called radial velocity technique, which consists of measuring the velocity of the star around the center of gravity of the star-planet syst...

The European Union regulations require safety and health protection of workers who are potentially at risk from explosive atmosphere areas. According to the requirements, the operators of installations where potentially explosive atmosphere can occur are obliged to produce an explosion protection document. The key objective of this document is the assessment of explosion risks. This paper is co...

[1] Calculations of radiative transfer in CO2-rich atmospheres are central to modeling the early climate of Earth and Mars. Line-by-line radiative transfer models are the most accurate means of carrying out such calculations and provide the basis for all other radiative transfer approaches. We examine the sensitivity of line-by-line results to three parameterizations of line and continuum absor...

We calculate the formation of dust clouds in atmospheres of giant gas-planets. The chemical structure and the evolution of the grain size distribution in the dust cloud layer is discussed based on a consistent treatment of seed formation, growth/evaporation and gravitational settling. Future developments are shortly addressed.

We review the basic concepts, present state of theoretical models, and the future prospects for theory and observations of pulsating stellar atmospheres. Our emphasis is on radially pulsating cool stars, which dynamic atmospheres provide a general example for the differences with standard static model atmospheres.

The course of respiration in control leaves of tobacco (Nicotiana tabacum L.) that were illuminated 4 to 5 hours and then darkened 0.25 to 10 hours and in tobacco leaves starved of carbohydrate by 14 hours or more of darkness was measured as CO(2) efflux in light and darkness into CO(2)-free atmospheres containing 0.04, 2.23, 21, 40, and 100% O(2).Control and starved leaves showed a postillumin...

Blood was cultured in two vacuum bottles containing Columbia broth. Filtered air was admitted to one bottle (aerobic); the unvented bottle was considered anaerobic. Cultures were incubated at 35 C until growth occurred or for at least 7 days. Of 744 organisms isolated, 50% were isolated from both bottles, 30% from the aerobic bottle only, and 20% from the anaerobic bottle only. These results in...
