1. 1. Use of Cellulose for the Preparation of Capsules and Beads with Molecularly Tailored Properties

   Författare :Katarzyna Mystek; Lars Wågberg; Bernard Cathala; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regenerated cellulose; partially modified cellulose; capsules; beads; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The continuously increasing global production of petroleum-based polymers to meet the ever growing demand for plastics for use in a multitude of industrial sectors (e.g. packaging and textiles) has an impact on human health, climate change and the entire ecosystem. LÄS MER

3. 2. On the Launching of Evaluation Capsules From a Ship in Beam Seas. Numerical and Experimental Investigations of Ship Motions, Wave Climate and Capsule Dynamics

   Författare :Philip Ekman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The process of evacuating a passenger ship in a seaway can be difficult and providedangerous situations for the passengers. The ship motions and the wave climate in thevicinity of the ship are factors that influence the launching process. LÄS MER

4. 3. Peptidergic innervation of periarticular tissue : a study in the rat

   Författare :Paul Ackermann; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Immunohistochemistry; radioimmunoassay; pain measurement; Achilles tendon; collateral ligaments; joint capsules; tendon rupture; regeneration; peripheral nervous system; neuropeptides; delta opioid receptor;

   Sammanfattning : Painful musculo-skeletal disorders pose a tremendous burden on the healthcare system, the main reason being the limited knowledge of the underlying pathomechanisms and lack of specific treatment. Hypothetically, the peripheral nervous system in the musculo-skeletal tissues plays an important role in the regulation of pain, inflammation, vasoactivity and also tissue repair. LÄS MER

5. 4. Evaluation of Alginate Microcapsules for Use in Transplantation of Islets of Langerhans

   Författare :Aileen King; Simon Howell; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Alginate; biocompatibility; cytokines; epimerases; islet transplantation; microencapsulation; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Transplantation of islets of Langerhans is a potential treatment of type 1 diabetes that aims to restore normal glucose homeostasis. Microencapsulation of islets could enable transplantation in the absence of immunosuppression, which would be beneficial as the side effects associated with immunosuppression outweigh the potential benefits of islet transplantation.

7. 5. Concepts for improving ethanol productivity from lignocellulosic materials : encapsulated yeast and membrane bioreactors

   Författare :Päivi Ylitervo; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulated yeast; Biofuel; S. cerevisiae; Membrane bioreactors; Thermotolerance; Furfural; Acetic acid; Resource Recovery; Resursåtervinning; Resource Recovery;

   Sammanfattning : Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials.
