The cleavage rate of oocytes matured under the typical gas atmosphere of 20% O{dollar}sb2{dollar} was higher than after IVM under reduced oxygen of either 5 or 10% O{dollar}sb2.{dollar} Development rate to the blastocyst stage was higher when embryos were matured under reduced oxygen (5%...
but the longer-term effects have received less attention. Yet these effects could be very significant, as persistent increases in global mean temperatures may ultimately influence the large-scale processes in the coupled ocean–atmosphere system that are thought to play a central...
Photosynthetic Co 2 fixation of higher plants is markedly inhibited by oxygen in concentrat... O Björkman - 《Physiol Plant》 被引量: 208发表: 1966年 Impacts of increased atmospheric CO2 concentration on photosynthesis and growth of micro- and macro-algae pump to absorb CO from the atmosphere...
Stable isotopes of hydrogen (δ2H) and oxygen (δ18O) provide important quantitative measures of lake hydrology and water balance, particularly in lakes where monitoring of fluxes is incomplete. However, little is known of the relative effects of seasonal variation in water isotopes on estimates of...
Furthermore, SO2 can be the cause of sulfate aerosol formation. Hydrodesulfurization (HDS) has been used to reduce the sulfur composition. Hwever increasingly higher and higher temperatures and pressure are required to improve sulfur removal using HDS, leading to increased costs and atmosphere ...
Lakes were the main water bodies in the Qinghai Lake Basin, whereas graff, bottomland, glaciers, and snow-covered regions accounted for a minority of water bodies. The area of water bodies decreased at first and then increased from 1977 to 2018. In 1977, the area of water bodies was 5574....
(95% CI 1.002–1.024) associated with a 1-day lag in wildfire smoke exposure (but not associated with any other lags from same day to a 4-day lag) [11]; respiratory deaths in middle aged adults were particularly increased with an odds ratio of 1.35 (95% CI 1.09, 1.67). The ...
The Parties to the Montreal Protocol are informed by three Panels of experts. One of these is the Environmental Effects Assessment Panel (EEAP), which deal
The [O2]/[Ar] ratio in the sputtering gas increased, the dielectric constant of the BST thin film increased owing to the improved crystallinity of the BST film. It is considered that the oxygen-rich atmosphere during the deposition of BST thin films promoted the formation...
As the pressure is increased, both the lower and the higher boundaries for the process are shifted toward higher temperatures. Overall, the temperature range for NO reduction appears to be slightly broadened. The shift in chemistry toward higher temperatures is most pronounced at low oxygen ...
