2. 1. Controlled axonal outgrowth and cell reactions to nanostructures

   Author : Fredrik Johansson; Funktionell zoologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Contact guidance; neuron; axon; fibroblast; macrophage; polymethylmethacrylate; porous silicon; nanowire; magnetic; immunoresponse; nanoimprint lithography; haptotaxis;

   Abstract : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. READ MORE

   Author : João Gomes; Björn O. Karlsson; Mats Rönnelid; Göran Lundgren; Heimo Zinko; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Energy; Photovoltaic-Thermal PVT ; Concentration; Collector Testing; Silicon Cell Encapsulation; Ray Tracing; Market Survey; String Layout; Prototype Collectors; Solenergi; Fotovoltaisk-termisk PVT ; Koncentration; Solfångarprovning; Inkapsling av kiselceller; Strålgångsberäkning; Marknadsundersökning; Strängdesign; Solfångarprototyper; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Fossil fuels have greatly improved human living standards and saved countless lives. However, today, their continued use threatens human survival, as CO2 levels rise at an unprecedented pace to levels never seen during human existenceon earth. READ MORE

5. 3. Blood protein coated model biomaterials : preparation, and cell and tissue response

   Author : Eva Jansson; Hans Elwing; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Solid biomaterials are widely used in bone and in soft tissue applications. Problems may then arise due to a prolonged inflammation in the proximity of the implant, resulting in the formation of a fibrous capsule and a low vascularisation near the interface. READ MORE

6. 4. Dosimetry Studies of Different Radiotherapy Applications using Monte Carlo Radiation Transport Calculations

   Author : Shirin Abbasinejad Enger; Hans Lundqvist; Anders Ahnesjö; Irena Gudowska; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; External Beam Radiotherapy; Gadolinium Neutron Capture Therapy; Gadolinium Neutron Capture Brachytherapy; Targeted Radionuclide therapy; Detector Response Modelling; Monte Carlo Simulation.; Radiological physics; Radiofysik;

   Abstract : Developing radiation delivery systems for optimisation of absorbed dose to the target without normal tissue toxicity requires advanced calculations for transport of radiation. In this thesis absorbed dose and fluence in different radiotherapy applications were calculated by using Monte Carlo (MC) simulations. READ MORE

7. 5. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles

   Author : Marianna Yanez; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAMAM; Surfactant; SDS; Lipid; Bilayer; Model Biomembrane; Nucleolipid; DLPA; DLPU; DNA; RNA; Neutron Reflectometry; Poly amidoamine ; Interface; Adsorption; Polyelectrolyte;

   Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE
