1. 1. Aerodynamic performance in bat flight

   Författare :Jonas Håkansson; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Leptonycteris yerbabuenae; Plecotus auritus; Glossophaga soricina; PIV; aerodynamics; wing morphology; bats; wind tunnel; animal flight;

   Sammanfattning : Bats are the only mammals capable of flight, and they are the only animal flyers that are mammals. This thesis focuses on the latter of those facts, and investigates how bats fly, from an aerodynamic perspective. LÄS MER

3. 2. A Workplace Prevention Program for Problem Gambling

   Författare :Jonas Rafi; Per Carlbring; Petra Lindfors; Anders Håkansson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; prevention; gambling; problem gambling; workplace; managers; longitudinal; randomized controlled trial; psykologi; Psychology;

   Sammanfattning : Gambling is an activity that may involve harm for the gambler and others close to the gambler. Since workplaces may be negatively affected by employees who gamble during work or are at-risk problem gamblers, this setting has been proposed as a suitable arena for prevention. However, the potential effects of such initiatives have not been evaluated. LÄS MER

4. 3. Social rörlighet i en socialt rörig tid : Eleverna och deras utbildning vid Brunnsvik, Väddö och Hola folkhögskolor, 1906–1921

   Författare :Jonas Söderqvist; Fredrik Sandgren; Kristina Lilja; Dan Bäcklund; Peter Gladoic Håkansson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social mobility; history of education; popular movements; folk high school; Swedish labour movement; prosopography; Brunnsvik; social rörlighet; folkrörelser; folkhögskolor; Brunnsvik; Hola; Väddö; arbetarrörelse; kollektivbiografi; nykterhetsrörelse; Ekonomisk historia; Economic History;

   Sammanfattning : In Sweden during the late 1800s, access to secondary education was not attainable for everyone. The school system separated pupils with parents who could afford to pay for tuition and boarding from those that came from less resourceful backgrounds.However, in a society in the throes of industrialization, this system was rapidly changing.

5. 4. Method Development in Quantitative and Structural Proteomics using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

   Författare :Charlotte Hagman; Per Håkansson; Jonas Bergquist; Jos Buijs; Michael Przybylski; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Cerebrospinal Fluid; Electrospray Ionization; Fourier Transform Ion Cyclotron Resonance Mass Spectrometry; Global Markers; High Performance Liquid Chromatography; Gas-Phase Exchange; Hydrogen Deuterium Exchange; Plasma; Protoemics; Quantification; Structural Elucidation; Bioteknik; Bioengineering; Bioteknik;

   Sammanfattning : In this thesis, methods for studying different aspects of proteomics were developed with Fourier Transform Ion Cyclotron Resonance, (FTICR), mass spectrometry. The FTICR technique provides ultra-high mass resolving power, mass accuracy at sub ppm level and sensitivity in the attomole region. LÄS MER

7. 5. Analysis of Complex Biological Samples using Liquid Chromatography-Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

   Författare :Margareta Ramström; Jonas Bergquist; Per Håkansson; Karin Markides; Carol Robinson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; mass spectrometry; liquid chromatography; protein; proteomics; peptide; Fourier transform ion cyclotron resonance mass spectrometry; cerebrospinal fluid; amyotrophic lateral sclerosis; electrospray ionization; electron capture dissociation; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Studies of protein and peptide expression are vital in order to understand complex biological systems. As demonstrated in this thesis, on-line packed capillary liquid chromatography-Fourier transform ion cyclotron resonance mass spectrometry (LC-FTICR MS) is a useful analytical tool for such studies.
