The recently announced results from the ICEP2 experiment are intepreted as an indirect observation of inflation gravitational waves. In this article we briefly discuss the cosmic inflation hypothesis, what is the B-mode, how it was measured, and why the polarization of the cosmic microwave background radiation can reveal how strong gravitational waves were present in the universe during this early epoch., Tomáš Ledvinka., and Obsahuje seznam literatury
We compared light-saturated photosynthetic rates and their stomatal limitations among Cryptomeria japonica trees with a similar height but different current growth rates. Although
slow-growing trees had a lower stomatal conductance and a higher carbon isotope ratio in shoots, the stomatal limitations in photosynthesis were not different. Large mesophyll CO2 diffusion resistance contributed to the low photosynthetic rate of the
slow-growing trees., T. Tange ... [et al.]., and Obsahuje bibliografii
