The GHK relationship is
It is depicted by the "black" curve where
[K+]o varies from 0.1 to 140.0 mM along the X axis
[K+]i is set by the investigator.
[K+]o varies from 0.1 to 140.0 mM and
[K+]i and alpha are set by the investigator.
Experiment with altering [K+]i and/or alpha to
see how changes in these values alter the membrane potential for any given
value of [K+]o .
If the application is not working, the following steps may restore functionality:
- Open your Java control panel and select the 'Security' tab.
- Select "Edit Site List" and click "Add"
- Enter the following http://nba.uth.tmc.edu
- Click "OK" - You may receive a Security Warning stating 'Including and HTTP location is a risk...', Click "Continue"
- You should now see the NBA domain in your "Exception Site List". If not, repeat the steps above.
- Click "OK" to finish.
- You may need to enable the "NPAPI" plug-in. For More information on the plug-in, visit: https://support.google.com/chrome/answer/6213033

How to temporarily enable NPAPI plugins
If you must use a NPAPI plugin, there’s a temporary workaround that will work until Chrome version 45 is released later in 2015:
- Open Chrome.
- In the address bar at the top of the screen, type chrome://flags/#enable-npapi
- In the window that opens, click the link that says Enable under the Enable NPAPI flag.
- In the bottom left corner of the page, click the Relaunch Now button.
After the release of Chrome version 45, you’ll need to use an alternate web browser to load content that requires a NPAPI plugin.
