Bubble dynamics during the non-isothermal degassing of liquids. Exploiting microgravity conditions.
This work reviews the up to date state of understanding of dynamic phenomena occurring when gas bubbles grow over submerged heated surfaces. Gas bubbles are produced on hot surfaces because the adjacent liquid layers become superheated causing local desorption of dissolved gases while the liquid far afield remains at low temperatures. Non-isothermal degassing is a very complex process combining...
متن کاملAltered Baseline Brain Activity with 72 h of Simulated Microgravity – Initial Evidence from Resting-State fMRI
To provide the basis and reference to further insights into the neural activity of the human brain in a microgravity environment, we discuss the amplitude changes of low-frequency brain activity fluctuations using a simulated microgravity model. Twelve male participants between 24 and 31 years old received resting-state fMRI scans in both a normal condition and after 72 hours in a -6° head down...
متن کاملdegassing in the Oregon Cascades
The carbon isotope content of dissolved inorganic carbon was measured for large cold springs in the central Oregon Cascades. Low 14C activities in some of the springs are interpreted to result from the dissolution of diffuse emissions of magmatic CO2, even though volcanic activity has not occurred in this area for more than 1300 yr. On the basis of dissolved magmatic carbon concentrations in th...
متن کاملFlow boiling of FC-72 from a screen laminate extended surface matrix
An investigation is conducted to assess the thermal performance of multi-layered screen laminates when used as extended surface matrices (ESM’s) in vertical up-flow boiling. A dielectric coolant (FC-72) is used as the working fluid. Four specimens are constructed having different mesh-geometries and/or number of layers. Channel Reynolds numbers are varied from 2700 to 8500 and ESM base superhea...
متن کاملThe Role of Microgravity in Cancer: A Dual-edge Sword
Since human beings could travel beyond the earth atmosphere, scientists started to investigate the effect of microgravity on human cells. Microgravity has different effects on normal and cancer cells, but the related mechanisms are not well-known till now. The aim of the present review is to focus on the consequences of exposing the cancer cells to reduced gravity. Some cancer cells organize th...
