Gaia is ESA’s ambitious space astrometry mission with a foreseen launch date in early 2012. Its main objective is to perform a stellar census of the 1000 Million brightest objects in our galaxy (completeness to V=20 mag) from which an astrometric catalog of micro-arcsec level accuracy will be constructed. A key element in this endeavor is the Astrometric Global Iterative Solution (AGIS) - the math

Vännerna från skoltiden har för många en stor betydelse. När den kände palestinsk-amerikanske litteraturvetaren Edward W. Said skrev sitt livs historia insåg han att just vännerna från sina tidiga skolår påverkat hans liv mer än vad andra vänner gjort. I "Utan Hemvist" berättar han också om sin mamma. När mamman talade om en person som hon uppskattade och spenderade mycket tid tillsammans med på ä

Popular Abstract in Swedish Syftet med den här avhandlingen har varit att studera association och växelverkan mellan proteiner och polymerer. Två olika tekniker har använts i dessa studier; datorsimuleringar och fördelning i polymera vattenhaltiga tvåfassystem. Vikten av att studera protein-polymer-växelverkan ligger i att flera biotekniska, och medicinska tillämpningar baserar sig just på proteiThe aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. The results showed that monovalent salt only slightly increases the hydrophob

The research presented in this thesis is focused on characterization of photophysical properties of lowest singlet excited states of carotenoids and their functions in the process of photosynthetic light harvesting. It is shown that the various light-harvesting complexes utilize different strategies to achieve efficient energy transfer from carotenoids to (bacterio)chlorophylls. Any study of energ

We present new polynomial-time approximation schemes (PTAS) for several basic minimum-cost multi-connectivity problems in geometrical graphs. We focus on low connectivity requirements. Each of our schemes either signifi- cantly improves the previously known upper time-bound or is the first PTAS for the considered problem. We provide a randomized approximation scheme for finding a biconnected graph

This chapter focuses on lessons from the arts to qualitative research, especially, what reflection on jazz improvisation may bring to qualitative research. One lesson concerns the dynamics of different kinds of authenticity. Just as jazz improvisation can be authentic in more than one way, so can research. Another lesson concerns the dynamics of observation and interpretation. Just as jazz improvi

A concise history of libraries in Sweden in the 18th century, covering the spectrum from national and university libraries over parish and circulating libraries to private collections for instruction and pleasure, with an emphasis on their users and usefulness.

Young people with migration background in Germany are often seen as having or producing problems. In this chapter, I discuss aspects of the German dominant discourse which still constructs this society as culturally and linguistically homogenous. I confront this perspective with language-based expressions by Germans with migration experience in e.g. Rap texts or political manifestos. While it is n
