1. 21. The Regulation of Growth and Survival in Human Multiple Myeloma Cells by IGF-I Receptor Signaling

   Författare :Thomas Strömberg; Helena Jernberg Wiklund; Kenneth Nilsson; Anders Waage; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; Multiple myeloma; IGF-IR; apoptosis; somatostatin; octreotide; dexamethasone; GSK-3; mTOR; rapamycin; RTK inhibitor; Patologi; Pathology; Patologi;

   Sammanfattning : Multiple myeloma (MM) is an incurable B-cell malignancy mainly localized to the bone marrow. Our aim was to examine the growth- and survival-promoting role of the IGF-IR and its downstream signaling components in MM cells to identify potential targets for therapy. LÄS MER

3. 22. Intramolecular isotope analysis reveals plant ecophysiological signals covering multiple timescales

   Författare :Thomas Wieloch; Jürgen Schleucher; Mats Nilsson; Gerd Gleixner; Lisa Wingate; Umeå universitet; []

4. 23. Coated Surfaces for Inkjet-Printed Conductors

   Författare :Thomas Öhlund; Hans-Erik Nilsson; Jonas Örtegren; Jouko Peltonen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet; Nanoparticles; Paper; Flexible substrates; Sintering; Printed Electronics; Functional Printing;

   Sammanfattning : In this thesis, a number of commercially available paper substrates of various types are characterized and their characteristics related to the performance of inkjet-printed conductors using silver nanoparticle ink. The evaluated performance variables are electrical conductivity as well as the minimum achievable conductor width and the edge raggedness. LÄS MER

5. 24. Dangerous Liaisons : Why Ex-Combatants Return to Violence. Cases from the Republic of Congo and Sierra Leone

   Författare :R. Anders Nilsson; Thomas Ohlson; Kristine Höglund; Mats Hammarström; Joanna Spear; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ex-combatants; reintegration; demobilization; DDR; conflict resolution; peacebuilding; civil wars; Republic of Congo; Sierra Leone; Peace and conflict research; Freds- och konfliktforskning;

   Sammanfattning : After disarming and demobilizing, why do some ex-combatants re-engage in organized vio-lence, while others do not? Even though former fighters have been identified as a major source of insecurity in post-civil war societies due to their military know-how, there have been few efforts to systematically examine this puzzle. This study fills this research gap by comparing the presence or absence of organized violence in different ex-combatant communi-ties – all the former fighters that used to belong to the same armed faction and who share a common, horizontal identity based on shared war-and peacetime experiences.

7. 25. Mercerization and Enzymatic Pretreatment of Cellulose in Dissolving Pulps

   Författare :Heléne Almlöf Ambjörnsson; Ulf Germgård; Thomas Nilsson; Storker Moe; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkali; carboxymethyl cellulose; cellulose I; cellulose II; cellulose dissolution; degree of substitution; enzymatic treatment; filterability; gel formation; mercerization; multivariate analytical methods; NIR FT Raman spectroscopy; sodium hydroxide; zink oxide; Chemical Engineering; Kemiteknik;

   Sammanfattning : This thesis deals with the preparation of chemically and/or enzymatically modified cellulose. This modification can be either irreversible or reversible. Irreversible modification is used to prepare cellulose derivatives as end products, whereas reversible modification is used to enhance solubility in the preparation of regenerated cellulose. LÄS MER
