Comparative genomics highlight the importance of lineage-specific gene families in evolutionary divergence of the coral genus, Montipora

open access: yesBMC Ecology and Evolution, 2022
Background Scleractinian corals of the genus Montipora (Anthozoa, Cnidaria) possess some unusual biological traits, such as vertical transmission of algal symbionts; however, the genetic bases for those traits remain unknown.

The transient response of global-mean precipitation to increasing carbon dioxide levels [PDF]

open access: yes, 2010
The transient response of global-mean precipitation to an increase in atmospheric carbon dioxide levels of 1% yr(-1) is investigated in 13 fully coupled atmosphere-ocean general circulation models (AOGCMs) and compared to a period of stabilization ...

Boundary layer new particle formation over East Antarctic sea ice – possible Hg-driven nucleation? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Aerosol observations above the Southern Ocean and Antarctic sea ice are scarce. Measurements of aerosols and atmospheric composition were made in East Antarctic pack ice on board the Australian icebreaker Aurora Australis during the spring of 2012.

Atmospheric Mass Loss During Planet Formation: The Importance of Planetesimal Impacts [PDF]

open access: yes, 2014
We quantify the atmospheric mass loss during planet formation by examining the contributions to atmospheric loss from both giant impacts and planetesimal accretion. Giant impacts cause global motion of the ground.

Global Warming Potential of New Gaseous Refrigerants Used in Chillers in HVAC Systems

open access: yesEnergies, 2022
Due to the global warming and resulting problems, attention has been paid to greenhouse gases released into the atmosphere since the 1980s and 1990s. For this reason, the Montreal Protocol and the Kyoto Protocol have tightened regulations on the use of ...

High temperature X-ray diffraction and thermo-gravimetrical analysis of the cubic perovskite Ba0.5Sr0.5Co0.8Fe0.2O3-δ under different atmospheres [PDF]

open access: yes, 2015
Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) with the cubic perovskite structure is known to be metastable at low temperature under an oxidizing atmosphere. Here, the thermal and chemical expansion of BSCF were studied by in situ high temperature powder X-ray ...
