1. Botulinum Toxin : Formulation, Concentration and Treatment
Sammanfattning : 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. LÄS MER
2. Development of Multi-grit cBN Grinding Wheel for Crankshaft Grinding
Sammanfattning : 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. LÄS MER
3. Element transport in aquatic ecosystems – Modelling general and element-specific mechanisms
Sammanfattning : 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. LÄS MER
4. Element transport in marine coastal ecosystems – modelling general and element-specific mechanisms
Sammanfattning : 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. LÄS MER
5. Development of Concentrating Photovoltaic-Thermal Solar Collectors
Sammanfattning : 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. LÄS MER
