Ph.D. Status Report

Half year report number 6: Fall 1998

Name: Søren Bertil Fabricius Dorch , Cpr.nr. 100471-XXXX.

Project title: The Solar Dynamo.

Supervisor: Åke Nordlund.

Study period: October 1st, 1995 -- December 18th 1998.

According to the Natural Science Faculty of the University of Copenhagen, the Ph.D.-comitee of the Niels Bohr Institute and the Ministry of Education, there are certain requirements to be fulfilled before the title of Ph.D. can be rewarded.

Below I have indicated how I atempt to fullfill these requirements:

Section 1: "Course-work"

The requirement is that participation in study groups, courses, summer and winter schools amount to at least 900 hours, 12 university scholar-points or 1 full term of course-work. Below I have indicated how I have fullfilled this demand.

Section 4: "Written presentation (publications and reports)"

Publications are expected during the Ph.D.-study. Normally the bulk of the publications will follow the thesis. Here I show articles, papers, reports and posters produced after I begun my Ph.D.-study (October 1., 1995). All are related to either courses, lectures or research-presentations relevant to the Ph.D.-study. I have also included a few articles that are under preperation.
