Positron emission tomography (PET) is a functional imaging technique, meaning it can measure the metabolic activity of cells with an unprecedented sensitivity. Established applications are the diagnosis and staging of cancer, neurological diseases, such as Alzheimer’s, and cardiac diseases [1]. Due ...

On a finer scale the ferrite is a “Body Centered Cubic” microstructure which can be represented by the following “unit cell” or the smallest possible unit which can describe the arrangement of atoms: A BCC microstructure has an atom on each corner and one atom in the center, and is “...
The simplest filter is a decoupling capacitor from the signal line or pin to ground. The capacitor C combines with the output impedance of the source ROUT to give a 1-pole low-pass filter with a roll-off of 20 dB per decade above the 3-dB cutoff frequency f C given by: Adding an ...
Equilibrium equations are generated from the free body diagram of a given system. This means that one FBD has different equilibrium equations from another. These equilibrium equations are as follows: a) Sum of forces along x-axis. Conventionally, the right direction is treated as positive. b...
Overview of Chemistry Terms 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, ...
The alpha phase is called ferrite. Ferrite is a common constituent in steels and has a Body Centred Cubic (BCC) structure [which is less densely packed than FCC]. Fe3C is called cementite and lastly (for us), the "eutectic like" mixture of alpha+cementite is called pearlite. Why is ceme...
A solid cube of silver has a mass of 90.0 g. What is the resistance between opposite faces of the cube? Resistance: The resistance of an object is defined as the ability of that object to resist any electrical current flow. To calculate the resistanc...
be sure to have your cell phone protected. Or you canlearn herehow to legally turn your CB car radio into a powerful transmitter capable of emitting and receiving communications from hundreds of miles away. The ability to communicate over a distance is the cornerstone of coordination and a cohe...
However, it is also known that a particular metal/oxide interface with similar lattice mismatch has two or more ORs, in which the lattice mismatch alone is insufficient to explain the formation of the ORs. Previous calculations show that the ORs between metal film and oxide substrate are ...
