21. Optimisation Challenges in Pressurised Hot Water Extraction of Polyphenols: Extraction and Degradation Kinetics
Sammanfattning : Pressurised hot water is an environmentally friendly alternative to hazardous organic solvents such as methanol and heptane. One of the many applications of using pressurised hot water extraction (PHWE) is to extract polyphenols from plants. The challenges in PHWE lies with the optimisation of extraction yield. LÄS MER
22. Strategies for optimisation of 177Lu-octreotate therapy – exploring local administration and combination therapy regimens
Sammanfattning : Neuroendocrine tumours (NETs) are a group of heterogeneous tumour types that originate in hormone-producing organs. Patients with NETs are often diagnosed after the primary tumour has metastasised. LÄS MER
23. Quantifying image quality in diagnostic radiology using simulation of the imaging system and model observers
Sammanfattning : Accurate measures of both clinical image quality and patient radiation risk are needed for successful optimisation of medical imaging with ionising radiation. Optimisation in diagnostic radiology means finding the image acquisition technique that maximises the perceived information content and minimises the radiation risk or keeps it at a reasonably low level.

24. Modelling the Role of Nuclear Power and Variable Renewables in Climate Change Mitigation
Sammanfattning : As the number of people on Earth and our energy needs have increased the system for providing this energy has become ever more complex and complicated and thus the need for more systematic understanding of it has grown. However, change in energy system is slow and many of the challenges that we face such as mitigating climate change need global solutions. LÄS MER
25. Study of the Apparent Kinetics of Biomass Gasification Using High-Temperature Steam
Sammanfattning : Among the latest achievements in gasification technology, one may list the development of a method to preheat gasification agents using switched ceramic honey combs. The best output from this technology is achieved with use of water steam as a gasification agent, which is heated up to 1600 °C. LÄS MER
