The gross calorific value is the amount of energy produced when a substance is burned with excess oxygen in a bomb calorimeter.
I have performed a principal component analysis, with interesting results. Now I want to add new test subjects to the study. Can I use their data to calculate their component scores using the...

With a new optical measurement technology we would be able to measure the two dimensional deformation in (X and Y) of a building (e.g. bridge) on several points (10 or more, depends on setup)...

Hi, I want to do cluster analysis with large data table (163 variables with 1500 test persons). By PCA I found that about 20 significant components explain 75% of the variance. I also found that...

Why BaO (s) + H2O(l) ---> Ba 2+(aq) + 2 OH - (aq) if Oxygen loves owning all the electrons, why would it bind to hydrogen which competes with Oxygen for electron ownership more so than...

I heard an explanation about something being a better proton acceptor or lone pair donor but that doesn't make sense. I couldn't explain in in terms of acid-base theory. The hand-waving way I saw...

Dear all! Oxygen vacancies do raise negatively the Fermi level by increasing the negative charge in the semiconductor crystal structure. In the case of n-type semiconductors, I wonder if this...

One problem w the BOD bottle type of OUR measurement is that it can only be used in a system that is not DO limited (typically assumed about 2 mg/l or more). If the system is running at low DO and...
