1. 26. Oligarchs, State Power and Mass Opinion : A Study of the Role of Oligarchs in Post-Soviet Pseudo-democracies

   Författare :Tigran Babajan; Staffan Andersson; Torbjörn Bergman; Karl Loxbo; Joakim Ekman; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; oligarchs; post-Soviet pseudo-democracies; state power abuse; mass opinion; oligarker; postsovjetiska pseudodemokratier; missbruk av statens makt; folkopinioner; Statsvetenskap; Political Science;

   Sammanfattning : This thesis attempts to understand the role of oligarchs in post-Soviet pseudo-democratic regime trajectories. The two dominant, competing streams of prior work have emphasized either the importance of state power or that of mass opinion in these processes in order to explain why some regimes successfully maintain their grip on power, while others make gradual steps towards democratization.

3. 27. New Tools for Analysis of Wood and Pulp Components - Application of MALDI-TOF Mass Spectroscopy and Capillary Zone Electrophoresis

   Författare :Anna Jacobs; KTH; []
   Nyckelord :Capillary zone electrophoresis; carbohydrate composition; degree of acetylation; degree of polymerization; enzymatic hydrolysis; hardwood; hemicellulose; hexenuronic acid; lignin; MALDI-TOF mass spectroscopy; molar mass; molar mass distribution; olig;

   Sammanfattning : In the present thesis, capillary zone electrophoresis (CZE),matrix-assisted laser desorption/ionization time-of-flight massspectroscopy (MALDI-MS) and size-exclusion chromatography incombination with off-line MALDI-MS (SEC/MALDI-MS) have beenapplied successfully to the analysis of wood and pulpcomponents.The carbohydrate compositions of pulp and holocellulosesamples, as well as of isolated hemicellulose preparations,were determined employing enzymatic hydrolysis and subsequentanalysis of the saccharides released by CZE.

4. 28. Bone mass in the young athlete

   Författare :Ulrika Pettersson; Ronny Lorentzon; Olle Svensson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone mass; bone area; physical activity; muscle strength; body constitution; amenorrhea; puberty; adolescents; young aduts;

   Sammanfattning : Bone mass and bone size accumulate during childhood and adolescence and peak in the twenties. The obtained peak bone mass has been suggested to be a major determinant of bone mass even in the very elderly. LÄS MER

5. 29. Molecules and Dust around AGB stars : Mass-loss rates and molecular abundances

   Författare :Sofia Ramstedt; Hans Olofsson; Fredrik Schöier; José Cernicharo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AGB stars; mass-loss; circumstellar abundances; Formation and development of stars; Stjärnors bildning och utveckling; Astronomy; astronomi;

   Sammanfattning : All stars with a stellar mass of about 0.8–8 MSun will end their lives as asymptotic giant branch (AGB) stars. Through their extensive mass loss the AGB stars constitutes an important source of nuclear processed material. LÄS MER

7. 30. Mass spectrometric studies of cellulose ethers

   Författare :Dane Momcilovic; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Polymer technology; Analytisk kemi; Analytical chemistry; enzymatic depolymerisation; reductive amination; electrospray ionisation; cellulose ethers; MALDI; mass spectrometry;

   Sammanfattning : Cellulose based derivatives, such as cellulose ethers, today find many applications in a diverse range of fields. The numerous applications put high demands on the technological performance of the cellulose ethers. LÄS MER
