2. 1. Botulinum Toxin : Formulation, Concentration and Treatment

   Author : Alma Rystedt; Dag Nyholm; Carl Swartling; Klas Nordlind; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Botulinum toxin; Botox; Dysport; Xeomin; NeuroBloc; Hyperhidrosis; Cervical dystonia; Neurology; Neurologi;

   Abstract : Botulinum toxin (BTX) is used in various fields of medicine, including the treatment of hyperhidrosis and cervical dystonia. Botox®, Dysport®, Xeomin® and NeuroBloc® are commercially available BTX products, which are formulated differently and their dosing units are unique. READ MORE

4. 2. Development of Multi-grit cBN Grinding Wheel for Crankshaft Grinding

   Author : Nastja Macerol; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive; cBN; grinding; vitrified bond; grit shape; grit concentration; morphology; aspect ratio; crankshaft; grinding wheels;

   Abstract : Crankshaft is a geometrically challenging component to grind. Over the years a number of grinding strategies have been developed to overcome thermal damage issues and excessive wheel wear. Radial and angular plunge processes have been adopted on some of the production machines. Recently a new, temperature-based strategy, has been proposed. READ MORE

5. 3. Element transport in aquatic ecosystems – Modelling general and element-specific mechanisms

   Author : Lena Konovalenko; Clare Bradshaw; Ulrik Kautsky; Linda Kumblad; Dan Baird; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; radionuclides; elements; concentration ratio; bioaccumulation; biomagnification; fish; modelling; aquatic food web; ecosystem; Cs; Sr; environmental risk assessment; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Radionuclides are widely used in energy production and medical, military and industrial applications. Thus, understanding the behaviour of radionuclides which have been or may be released into ecosystems is important for human and environmental risk assessment. READ MORE

6. 4. Element transport in marine coastal ecosystems – modelling general and element-specific mechanisms

   Author : Lena Konovalenko; Clare Bradshaw; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modelling; bioaccumulation; concentration ratio; radionuclides; marine foodweb.; Marine Ecology; marin ekologi;

   Abstract : Understanding the behaviour of naturally-occurring and anthropogenically-derived radionuclides (isotopes) in the marine environment is important, because there is a need for their effective utilization either as in situ tracers or for industry, medical applications, the planning of waste-disposal facilities, and estimations of human and animal health risks. Radionuclides generally have the same chemical properties as their stable element analogues and thus show similar environmental behaviour and cycling to their stable counterparts. READ MORE

7. 5. Development of Concentrating Photovoltaic-Thermal Solar Collectors

   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
