a proton pump encoded byatpD47, not only pumps out intracellular protons to maintain intracellular pH but also produces ATP to promote bacterial growth and survival53. Inhibition ofatpDexpression inS. mutansUA159 resulted in a significant decrease in acid adaptation and...
How many unpaired electrons are present in the ground state ruthenium atom? How many unpaired electrons does Ir3+ have in its ground state? How many unpaired electrons are in the ground state of Co3+? How many unpaired electrons are there in the ground state of As? How many...

All elements are arranged in the periodic table by their atomic number -- the number of protons in their nucleus. Aluminum's lucky number is 13, so an aluminum atom has 13 protons. It also has 13 electrons. The elements located above and below aluminum on the periodic table form a ...
Titanium plus helium produces chromium. Chromium plus helium produces iron. Other fusion pathways create the elements with odd numbers of protons. Iron has such a tightly bound nucleus that there isn't further fusion once that point is reached. Without the heat of fusion, the star collapses and...
Chapter 9: What Are the Health and Environmental Effects of Titanium Metal? Titanium cannot be found naturally in its metallic state. In urban environments, its concentration in the air is typically below 0.1 µg/m³. However, in areas near factories, levels can reach up to 1.0 µg/m...
MRI became much more useful for constructing an internal image of the body when a phenomena known as relaxation time, the time it takes for the protons to emit their signal, was taken into consideration. In all body tissues, there are two types of relaxation times, T1 and T2, that can ...
