The thermal structure of Titan's atmosphere [PDF]
Icarus, 1989 We have developed a radiative-convective model of the thermal structure of Titan's atmosphere. The model computes the solar and infrared radiation in a series of spectral intervals with vertical resolution. Sources of opacity in the visible and near infrared include stratospheric haze particles, methane cloud particles, and gaseous methane; sources ...

Relations among atmospheric structure, refraction, and extinction
Comptes Rendus. Physique, 2023 The refraction and extinction in the Earth’s atmosphere depend on the atmosphere’s structure, so it was natural to try to infer that structure from optical observations.

Atmospheric Structure and Composition
, 2009 Titan's atmosphere is predominantly N2 with CH4 the next most abundant molecule. It has a mole fraction of 0.05 just above the surface decreasing to 0.014 in the stratosphere. Above the homopause (~800–850 km), it increases to 0.12 at the exobase. The third abundant molecule is H2 with a tropospheric mole fraction of 0.001 increasing to 0.004 at ~1000 ...

Atmospheric turbulence structure above urban nonhomogeneous surface
Russian Journal of Earth Sciences, 2022 A new 21-meter eddy covariance tower is installed in the Meteorological observatory of Moscow State University in November 2019. It includes 3 levels with METEK sonic anemometers. The mast is located inside the urban area and makes it possible to analyze

Rocky Planet or Water World? Observability of Low-density Lava World Atmospheres
The Astrophysical Journal, 2023 Super-Earths span a wide range of bulk densities, indicating a diversity in interior conditions beyond that seen in the solar system. In particular, an emerging population of low-density super-Earths may be explained by volatile-rich interiors.

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Concentration fluctuations in atmospheric dispersion [PDF]
, 1990 This report summarizes work done at Brunel University under Agreement No.2066/62 from 15 July 1986 to 14 July 1989. The title of the project was Concentration Fluctuations in Atmospheric Dispersion. The report has three principal components. These are:

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
