Pixel density is ameasure of how many pixels your monitor can display per inch. A smaller monitor will have a higher PPI (pixels per inch) than a larger monitor at the same resolution. Higher PPI is desirable, but at a certain point, the difference becomes undetectable. You will have a ...
This count of protons is called the atom's atomic number. The proton's nucleus-partner, neutrons, serve an important purpose; they keep the protons in the nucleus and determine the isotope of an atom. They're not critical to our understanding of electricity, so let's not worry about them...
Proton pump inhibitors Selective serotonin reuptake inhibitors recommend over age 65 diagnosed with a special test Healthy bone:–1.0 or above Osteopenia:between –1.0 and –2.5 Osteoporosis:–2.5 or lower Some people can be diagnosed with osteoporosis when they get a fracture, even if their T-sco...

At a field strength of 1.5T for example, the STN is very well visualised by a T2-weighted sequence, whereas the GPi is best visualised by a proton density-weighted sequence. SWI sequences are also proving to be very useful. The postoperative 'verification-MRI' needs to visualise the ...
The signal intensity in MRI depends on the proton density, T1, T2 and T2 relaxation processes of any ensemble of the spins within each imaging elements (voxel). Another important contrast mechanism in MRI is signal loss caused by proton dephasing in the presence of coherent and incoherent flow...
In any atom, like charges repel one another, and opposite charges attract one another. This is why two protons repel each other and so do two electrons, but a proton and an electron attract each other. In an element, the numbers of electrons and protons are equal. Moreover, since they...
Bone density or bone mineral density is the amount of bone mineral in the bone tissue. Bone density measurements are used in clinical medicine as an indicator of osteoporosis, a disease that makes your bones weak, and increases the risk of fractures. It can also indicate your response to trea...

The scientific study of matter's characteristics and behaviour is known as chemistry. Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that mak...
