About the position
In this position you will be a part of a larger project team within the Swedish Wind Power Technology Centre. The aim of this project is to develop well and suitable models of the electric drive system for integration with the mechanical system in a wind turbine. There are several different drive system used today, the project will develop and adopt models of the most common ones. In the later stage of the project is the goal to optimize and integrate the electrical and mechanical system for the future wind turbine. Validation against measurements of the used models is an important part of the project. Measurements in a 4 MW wind turbine are a part of the project. The work involves model development for generators,power electronic converters and analysis due to dynamic/transient behaviour in the grid. Also diagnostics methods will be developed; by using the models developed in the first part of the project, to investigate the possibilities to find failures in the wind turbine, both mechanical as well as electrical ones.

PhD Scholarship, Sweden

Scholarship Beasiswa | PhD Scholarship in Biophysical Chemistry

Last Day of Applying: 31 January 2011

Scholarship Overview :
The position is linked to the research project "Molecular basis of heat and desiccation tolerance of bacterial cells and spores", funded by Nestec Ltd, Lund University and the Swedish Research Council. The research work will be carried out at the Division of Biophysical Chemistry, which belongs to the Center for Molecular Protein Science in the Department of Chemistry. The Division is located at Lund University`s Center for Chemistry and Chemical Engineering (Kemicentrum). Kemicentrum is one of the largest research units for chemistry in Scandinavia with a staff of ca 400 and a yearly research budget of ca 350 million SEK. Research within the Division of Biophysical Chemistry ranges from water physics and nuclear spin relaxation theory to fundamental and applied problems in the life sciences, with a focus on protein interactions and dynamics.

Job assignments
All known life forms depend on water, but certain organisms, including bacteria, can survive lengthy periods of extreme dehydration (desiccation). This anhydrobiosis phenomenon is often coupled to high intracellular levels of certain disaccharides. The most stress tolerant life forms are endospores. These survival capsules, produced by some bacteria when deprived of nutrients, can remain in a metabolically dormant state for many years.

The aim of your research in this project is to elucidate the molecular mechanisms of desiccation tolerance and heat resistance in vegetative bacteria and endospores. These mechanisms likely involve protein stability and mobility, membrane permeability and enzyme activity. All of these factors are strongly influenced by biomolecule-water interactions. A major focus of the project is therefore to characterize the physical properties of water and proteins in intact cells and spores under different external conditions. This can be done with a specialized nuclear magnetic resonance technique, Magnetic Relaxation Dispersion (MRD), by measuring how the spin relaxation rate of deuterium nuclei depends on the applied magnetic field strength. For more information on the MRD technique, see: E Persson & B Halle, Cell water dynamics on multiple time scales, Proc Natl Acad Sci USA 105, 6266 (2008), and E P Sunde, P Setlow, L Hederstedt & B Halle, The physical state of water in bacterial spores, Proc Natl Acad Sci USA 106, 19334 (2009).

Your main research activities in this project will be MRD and other biophysical experiments, quantitative analysis of the resulting data, and development and testing of models of desiccation tolerance and heat resistance. You will also culture bacteria and prepare samples for MRD measurements. Strains of vegetative bacteria and ultrapure endospore preparations will be supplied by collaboration partners in the project: Nestlé Research Center, Lausanne (bacterial strains) and prof Peter Setlow, University of Connecticut (endospores). These collaboration partners will also contribute microbiological expertise.

The resistance of bacteria and endospores to extreme environmental stress is not only a fascinating biological phenomenon. Inactivation of pathogenic bacteria and endospores that can survive in a desiccated state and also withstand high temperatures is of vital concern in the food industry. An interesting question that also will be addressed in the project is how to use fundamental understanding of molecular mechanisms to improve existing methods for inactivating contaminating bacteria or endospores in food preparations.

As a doctoral student you will mainly be working with your research project, but you can also be given other tasks, such as teaching or instrument responsibilities. If you engage in undergraduate teaching, the PhD position will be extended by a corresponding period. Within the project you will travel to visit collaborating laboratories and to participate in international conferences.

Regulations for employment as a postgraduate student can be found in the Swedish Statute Book (SFS 1998:80).

Eligibility/Entry Requirements
The general eligibility requirement for doctoral studies is a university degree of at least 240 ECTS credits, including at least 60 credits at an advanced level.

We also welcome applications from highly motivated students who have not yet obtained their degree but will do so in the first half of 2011.

Basis of Assessment
Employment as a doctoral student can only be granted if you have been accepted to the PhD study program. The selection to this program is based on an assessment of your ability to perform well in and benefit from the program. The assessment considers the following aspects in particular:

1. Documented knowledge and skills relevant to the research project and study results in particularly relevant courses.
2. Ability to work independently and to formulate and solve scientific problems. Such abilities can be demonstrated, for example, in a Master Thesis or in a discussion of scientific problems during a possible interview.
3. Other experience relevant to postgraduate studies, such as professional experience.

The specific eligibility requirement for this PhD position is an advanced degree in Chemistry, Biochemistry, Biophysics or a related discipline, including at least 50 credits of courses in mathematics, computer programming and molecular physics / biophysics or physical chemistry / biophysical chemistry.

Knowledge of and practical experience with nuclear magnetic resonance, protein science and/or microbiology is considered a merit.
We are seeking a highly motivated student with the ability to perform high-quality research work.
An excellent command of written and spoken English is a prerequisite.

Scholarship Sweden | PhD position in Systems and Control at Uppsala University

[Sweden] PhD position in Systems and Control at Uppsala University

Overview
The research group Systems and Control in the department of Information Technology of Uppsala University (Sweden) (http://www.it.uu.se/research/syscon) invites applications for a Ph.D. studentship. The successful applicant will work in the context of the ERC project on control engineering and modeling for biomedical systems. Especially motivated students with a strong background in engineering, computer science, applied mathematics or alike are encouraged to apply. This research will be conducted under supervision of Alexander Medvedev and Petre Stoica.

In this Ph.D. project we will explore different approaches to unravel complex interaction networks as observed in dynamical systems of the human body, especially with respect to endocrinology and neurology. As classical modeling tools are often not satisfactory for modeling of biological signals, ample room for improvement and further exploration of either theoretical or applied research remains in this area.
