The VP7 WKP is a GTK program which simulates the decay of radioactive nuclei. The user can do decay/activity measurements on various pre- or user defined materials. It is also possible to study the effectivity of aluminium, paper and lead as shields. Requirements: - GTK+

This m-file plots a NMR coupling diagram from coupling constants and number of splits (only 1/2-spin nuclei). Useful for educational purposes.Example: plotcoupling([8,2],[3,1])Produces a plot with the coupling constants 8 and 2 Hz, splitted three and one times, respectively.The screenshot is made...

This program calculates the spin lattice relation time (T1) and linewidth of a carbon atom relaxing by interacting with up 5 different nuclei by dipolar relaxation and or by Chemical Shift anisotropy (CSA) provided you know the rotational correlation time

GMR returns the gyromagnetic ratio and other NMR properties for various nuclei as well as the electron.Besides the function format, the command format will work as well, e.g. "gmr Na23 hzpt 3.0".Format: y=gmr(nucleus,unit,b0) "nucleus" = string or number specifying the nucleus (not case...

The Levenberg-Marquardt Fitting of Nuclear Decay Model demonstrates how EJS can be used to fit experimental data. In this simulation, nuclear decay data are used to provide a simple example, but this same process can be applied to any type of data. The sum of squared deviations is minimized but...

Is it a tumor? Magnetic Resonance Imaging (MRI) can tell. Your head is full of tiny radio transmitters (the nuclear spins of the hydrogen nuclei of your water molecules). In an MRI unit, these little radios can be made to broadcast their positions, giving a detailed picture of the inside of your...

The Two State Nuclear Decay model simulates the radioactive decay of atomic nuclei into other nuclei. In this model, the resultant nuclei are stable and there are no intermediate decay states. Although the decay of a radioactive nucleus (radionuclide) is spontaneous and the time of its decay...

This program is designed for health care professionals, students, and anyone interested in visualizing and learning about the complex neuroanatomy of the brain stem. The 3D features allow users to visualize the external morphology of the brain stem as well as the cranial nerve fibers and nuclei...

The VP7 Way Kool Project is the first official software by VP7. It is designed to simulate a laboratory experiment where the half life of radioactive nuclei can be measured using a Geiger-M?*N?ller detector and a counter. The counter is also able to show the activities of the nuclei and the user...

The EJS Radioactive Decay Distribution Model simulates the decay of a radioactive sample using discrete random events. It displays the distribution of the number of events (radioactive decays) in a fixed time interval. If each event is assumed to occur independently and spontaneously with a...

The Three State Nuclear Decay model extends the Two State Nuclear Decay model to simulate the radioactive decay of atomic nuclei in which the parent nucleus first decays into an intermediate state before decaying into a stable state. Although the decay of both the parent and intermediate nucleus...
