During his PhD studies, Nicklas Skovgaard Nyboe carried out research into the natural, cultural and instrumental noise phenomena that have an impact on environmental geophysical measurements, and into methods for suppressing the influence of the noise phenomena.
Nicklas Skovgaard Nyboe mainly studied these conditions in relation to a specific geophysical measurement method called the transient electromagnetic method (TEM). This is of particular interest because it plays a key role in the nationwide mapping of the Danish groundwater. Due to the fact that both ground and airborne instruments of this type are used, the relevant noise phenomena are numerous and quite diverse. The research results achieved led to considerable improvements in the quality of the signals that were measured, by means of developing a new measuring instrument and by improving methods for collecting and filtering data.
The PhD degree was completed at the Department of Geoscience, Science and Technology, Aarhus University.

Unique pump in sperm cells makes a difficult journey possible
2012.05.01 — In his PhD work, Michael Jakob Voldsgaard Clausen made a detailed study of a molecular pump that is essential for sperm cells and is not found in other types of cells. The job of a sperm cell is to carry genetic information from a male to a female. In order to carry out this project, the cell has to travel from the testicle to the ovary, where both the pH value and salt concentrations are drastically altered. His results show that this pump is specific to sperm cells and is adapted to be able to maintain stable activity in conditions in which there are changes to the salt concentrations and the membrane potential of the cell. In time, it is possible that his results could be used in developing a birth control pill for men. Michael Clausen defended his dissertation on 23 April 2012. PhD supervisors: Professor Poul Nissen and Postdoctoral Research Associate Hanne Poulsen. Listen to the interview with Michael Clausen on Radio24syv (in Danish) about his results. (The interview starts 45.22 min into the broadcast). More information Michael Jakob Voldsgaard ClausenDepartment of Molecular Biology and Genetics, Aarhus University, Denmarkmjc@mb.au.dk
