General comments to Downloads

The spreadsheets and papers mentioned in Downloads can be freely downloaded, and they are with one exception written by Jorgen Wagner.
They are technical and they demand membrane process knowledge. There is between little and no help built in.

About Errors. There may be errors in formulae and in the papers. But none are known to me in this moment. If errors are reported I can mostly fix them fast. Please report problems, errors, error messages, wishes to programs etc to


The spreadsheets (XLS/XLSX) are easy to install and difficult to keep in good shape. There is password protection on all cells except for those where data input is needed. If you mess up a sheet the best is probably to download it again.
Written in Microsoft Excel. If the extension is XLSX then it is Office 2007 or newer. You need an add-in from Microsoft to open the file in Office 2003 and earlier.

EXE-files have been removed and maintenance discontinued, since it is so much easier for me to maintain a spreadsheet. The modern type spreadsheet have functions which made them as powerful as EXE programs.

All files have been ZIP-ed to ensure faster download and to avoid problems with mail delivery. In 2011 I am using IZarc to UNZIP (and to ZIP) files

The papers are written in Star Office and Word Perfect and published in PDF format. Adobe Acrobat Reader (or the full version) is necessary to see the papers. The Adobe Acrobat Reader is installed on most PCs and MACs these days. If you do not have it, it can be freely downloaded from www.Adobe.com.
