Copper contents in the elution collected before and after the Cu cut revealed that Cu yields were > 99.5%. The total blank of the procedure was less than 3 ng (n = 26), which is negligible compared with the ~ 1.2 µg Cu loaded onto the resin. Cu isotope ratios were measured on ...
Answer to: Write out the balanced chemical equation for respiration, in an athlete, in a race. By signing up, you'll get thousands of step-by-step...
1. What is the fractional saturation of hemoglobin (Yo2) at 50 torr? 2. Assume that n=3 and P50 of 26 torr for this calculation. Can someone put the equation and label each part of the equation. Blood in the pulmonary arteries _...
The Carreau–Yasuda model is used to calculate the blood viscosity amount, which is a non-linear relationship between blood shear stress and shear flow rate. According to this model, blood viscosity is obtained from the following equation22. $${\eta }_{app}={\eta }_{\infty }+\left({\...
The adsorption data were used to calculate the apparent surface area (ABET) through the BET equation. The total pore volume (Vtotal) was determined by the amount of N2 adsorbed at the relative pressure p/p0 = 0.95. The micropore volume (Vmicro) was evaluated by the t-plot method, ...
The Middle Eocene Climatic Optimum (around 40 million years ago) was a roughly 400,000-year-long global warming phase associated with an increase in atmospheric CO2 concentrations and deep-ocean acidification that interrupted the Eocene’s long-term cool
For example, the ocean acts as a buffer against climate change by absorbing a large amount of atmospheric CO2. A large fraction of the absorbed CO2 is transformed into algal biomass. When algae die, the algal biomass can be partially converted by bacteria into refractory dissolved organic carbon...
Electrospinning is a promising technique for preparing bioartificial blood vessels. Nanofibers prepared by electrospinning can simulate the structure of ex
The change of a substance from a solid directly to a gas is referred to as {Blank}. What is the change in heat when 23.5 g water vapor at 100 C condenses to liquid 18.50 C? Can the temperature of a boiling liquid rise above its boiling point? Explain...
Thirdly, the Michaelis–Menten rectangular hyperbola model was used to calculate NEE [23]. The equation used was (4). NEE=(PPFD×−Pmax)Km+PPFD−RecoNEE=(PPFD×−Pmax)Km+PPFD−Reco (4) where NEE is the net CO2 flux of the rice ecosystem (μmolCO2 m−2 s−1)(μmolCO...
