The article cites a study which does not support the concept that increasing breathing resistance causes an increase in respirator facial leakage. Increase in faceseal leakage with increasing pressure drop was not exhibited by respirators that met the Occupational Safety and Health Administration ...

There were no significant differences in mean systemic arterial blood pressure, mean pulmonary artery pressure, systemic or pulmonary vascular resistance index, cardiac index, arterial pH, or Paco2. CONCLUSIONS: In the presence of sevoflurane, ketamine did not increase pulmonary vascular resistance in ...
aThis currently is known to be an error, because it is more difficult to produce crack-free blocks with higher zirconia contents because of the tetragonalto-monoclinic phase transformation. However, zirconia does increase corrosion resistance to soda–lime–silica glass. 由于tetragonalto两性花阶段变革...
Why is voltage constant in a parallel circuit? How badly has the shifting of magnetic poles affected our magnetosphere? How does increasing the resistance in a circuit affect the current in the wire? Why does the current split in a parallel circuit?
1A). All experiments were carried out with 3 mM ATP added in the patch pipette solution to block the participation of the maintained low voltage-activated current permeable to calcium and sodium identified on DUM neurons (Defaix and Lapied, 2005). It is interesting that an increase of Calcium...
Does resistance depend on temperature? Since the resistance of some conductor, such as a piece of wire, depends on collisions within the wire itself, theresistance depends on temperature. With increasing temperature, the resistance of the wire increases as collisions within the wire increase and "...
Each time a cell goes through an erase cycle, some charge is left in the floating-gate transistor, which changes its resistance. As the resistance builds, the amount of current required to change the gate increases. Eventually, the gate can't be flipped at all, rendering it useless. This ...
How does increasing the distance between charged objects affect the electric force between them? Three resistors 2.3 \Omega,\ 4.5 \Omega, and 8.8 \Omega are placed together in series. What is the total (equivalent) resistance? What is the relationship between current, resistance, and voltage dif...
Raising the voltage will, in a resistor circuit, increase the current. Current is the flow of charge so, for a given conductor cross-section, increasing the current must increase the charge velocity. The current, however, moves simultaneously all around the circuit the same way a bicycle chain...
