1. 1. DNA methylation profiling of CNS tumors; implications for clinical diagnostics

   Författare :Sandra Ferreyra Vega; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Central nervous system tumors; DNA methylation; clinical diagnostics; diffuse gliomas; meningiomas; heterogeneity;

   Sammanfattning : Diffuse gliomas and meningiomas are the most common primary tumors of the central nervous system (CNS) in adults and these tumors cause significant morbidity and mortality worldwide. Deregulation of the epigenetic mechanisms, e.g. LÄS MER

3. 2. Few nucleon systems at the exotic doubly magic region 132Sn

   Författare :Maria Sanchez-Vega; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

   Sammanfattning : The low-energy structure of 133Sn, 133Sb and 133Te has been studied. The levels of 133Sn were populated in the β-delayed neutron decay of 134In at the ISOLDE PS-Booster (PSB) mass-separator facility at CERN. The single-neutron states p3/2, h9/2 and f5/2 in 133Sn were identified at 853.7, 1560. LÄS MER

4. 3. Assessment of the lifetime of district heating pipes

   Författare :Alberto Vega; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FTIR; rigid polyurethane foam; artificial ageing; {District heating pipes; natural ageing; degradation mechanisms; mechanical performance;

   Sammanfattning : This thesis is concerned with the degradation and assessment of the lifetime of district heating pipes, where accelerated ageing is used to study the degradation in a short time frame. The project was divided into four interrelated parts. LÄS MER

5. 4. Degradation mechanisms and long-term performance of PUR insulation in district heating pipes

   Författare :Alberto Vega; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical performance; thermal conductivity; District heating pipe; degradation mechanisms; long-term performance; rigid polyurethane foam;

   Sammanfattning : District heating networks are used worldwide, especially in Scandinavian countries and also in many other countries, e.g. Germany, Russia, United States, South Korea and China. From an environmental point of view, district heating networks are a good alternative to more traditional building heating systems. LÄS MER

7. 5. Essays on health, labor market behavior, and economic incentives

   Författare :Alejandro Vega; Thomas Aronsson; Gauthier Lanot; David Granlund; Niklas Jakobsson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor force participation; labor supply; health status; financial risk-taking; gender differences; job loss; Economics; nationalekonomi;

   Sammanfattning : Paper [1] analyzes how the labor force participation changes in response to major health shocks, such as new cancer diagnoses, heart attacks, and strokes, in middle-aged to elderly Mexican couples, and how the spouses interact in their responses. The data originates from the Mexican Health and Aging Study and provides information on how couples coordinate their labor market activities in response to major health shocks. LÄS MER
