Learning objectives

I would like to thank those who have helped with the costs of this site. The idea is to keep the site free of adverts and to just add more and more quality information with time. More income can help to get professional illustrations and to improve the performance and appearance of the site. Even small donations such as 5-10 dollars/pounds/euros will go a long way to improving the content.

Patrons: Thank-you

  • Dr Youssif Abousleiman

Note: The plan is to keep the website free through donations and advertisers that do not present any conflicts of interest. I am keen to advertise courses and conferences. If you have found the site useful or have any constructive comments please write to me at drokane (at) I keep a list of patrons to whom I am indebted who have contributed. If you would like to advertise a course or conference then please contact me directly for costs and to discuss a sponsored link from this site.
