The PSD is usually determined over a list of size ranges that covers nearly all the sizes present in the sample. Some methods of determination allow much narrower size ranges to be defined than can be obtained by use of sieves, and are applicable to particle sizes outside the range available in sieves.

2-D tetra-lateral position sensitive device (PSD) A 2-D tetra-lateral PSD is capable of providing continuous position measurement of the incident light spot in 2-D. It consists of a single square PIN diode with a resistive layer. When there is an incident light on the active area of the sensor, photocurrents are generated and collected from ...
As an SPP propagates along the surface, it loses energy to the metal due to absorption. The intensity of the surface plasmon decays with the square of the electric field , so at a distance x , the intensity has decreased by a factor of exp { − 2 k x ″ x } {\textstyle \exp\{-2k_{x}''x\}} .
The PSD has been proposed to concentrate and organize neurotransmitter receptors in the synaptic cleft. [1] The PSD also serves as a signaling apparatus. For instance kinases and phosphatases in the PSD are activated and released from the PSD to change the activity of proteins located in the spine or are transported to the nucleus to affect ...
The PSD contained two main sections: The "market rules" described which type of organisations could provide payment services. Next to credit institutions (i.e. banks) and certain authorities (e.g. central banks, government bodies), the PSD mentioned electronic money institutions (EMI), created by the E-Money Directive in 2000, and created the new category of "payment institutions" (PI) with ...
In molecular biology, the Signal Peptide Peptidase (SPP) is a type of protein that specifically cleaves parts of other proteins. It is an intramembrane aspartyl protease with the conserved active site motifs 'YD' and 'GxGD' in adjacent transmembrane domains (TMDs). Its sequences is highly conserved in different vertebrate species.
