1. 1. Effects of Citric Acid on Starch-Based Barrier Coatings

   Författare :Erik Olsson; Lars Järnström; Caisa Johansson; Julien Bras; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Citric acid; Cross-linking; hydrolysis; Montmorillonite; WVTR; OTR; Barrier properties; Chemical Engineering; Kemiteknik;

   Sammanfattning : With growing environmental concerns, efforts are made to replace petroleum based products with renewable alternatives. This is particularly evident in the packaging industry, where replacing synthetic polymers with renewable materials is of considerable interest. LÄS MER

3. 2. The percieved threat of the risk of graft rejection among organ transplant recipients

   Författare :Madeleine Nilsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Organ transplantation; graft rejection; adolescents; perceptions; psychometric evaluation; health related quality of life; coping;

   Sammanfattning : Transplantation is an established and successful treatment for critically ill patients. For many of the organ transplant recipients (OTR) it is the only option for survival. When OTRs are asked about what they fear the most, the most common answer is graft rejection. LÄS MER

4. 3. Food and Packaging Interactions Affecting Food Quality

   Författare :Fredrik Johansson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sorbed vegetable oil; oxygen transmission rate; food packaging; supercritical fluid extraction; inertness test; refillable PET bottles; permeability; aroma; interactions; sorption;

   Sammanfattning : Food and packaging interactions that may impair the food quality have been studied and methods to determine these interactions have been developed. An off-line supercritical fluid extraction method using carbon dioxide was developed and used to extract sorbed low molecular weight compounds from polymer films. LÄS MER

5. 4. Resonant multi-photon ionisation studies of high-energy states in small molecules

   Författare :Marica Sjödin; Lars-Erik Berg; Arne Rosén; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : This thesis describes separate studies of high-energy Rydberg and ion-pair states in small molecules using resonant multi-photon ionisation spectroscopy. * OODR/REMPI study of ungerade Rydberg states in O2 The energy region between 75000 and 99900 cm-1 of O2 has been studied using optical-optical double resonance (OODR) with resonance enhanced multi-photon ionisation (REMPI).

7. 5. Cancer in organ transplant recipients

   Författare :Caroline Stenman; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; organ transplantation; skin cancer; heart transplantation; lung transplantation;

   Sammanfattning : Tens of thousands of transplantations are performed around the world each year. Organ transplant recipients (OTR) are obliged to receive life-long medical treatment with immunosuppressive drugs to ensure graft function. However, such medications entail an increased risk of developing a broad spectrum of malignancies, especially skin cancer. LÄS MER
