2. 16. Quantitative immunochemistry in tissue sections : With special reference to urinary bladder carcinoma

   Author : Kenneth Wester; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Urinary bladder carcinoma; immunohistochemistry; quantification; image analysis; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

   Abstract : Urinary bladder carcinoma affects about 2 000 people in Sweden every year. It is a heterogeneous disease and for adequate treatment decisions, prognostic tools are needed. Many of these are based on immunohistochemistry (MC) and hampered by poorly reproducible methodologies and subjective evaluations. READ MORE

4. 17. Investigating the impacts of Late Pleistocene climate change on Arctic mammals using palaeogenomics

   Author : Edana Lord; Love Dalén; Mirte Bosse; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; palaeogenomics; Arctic; Late Pleistocene; past climate; collared lemming; woolly rhinoceros; Norwegian lemming; muskox; demography; population structure; speciation; adaptation; genome erosion; Systematic Zoology; zoologisk systematik och evolutionsforskning;

   Abstract : The climatic fluctuations of the Late Pleistocene likely had a large impact on the evolutionary history of Arctic species. Palaeogenomics is a useful tool to shed light on how past populations responded to these climatic shifts and the associated ice sheet dynamics and sea level change. READ MORE

5. 18. Storage of Hydrogen Peroxide Bleached Mechanical Pulp : Reduction in Reflectance over the Visible Spectrum

   Author : Sofia Enberg; Per Engstrand; Magnus Paulsson; Mats Rundlöf; Patrik Axelsson; Øyvind Eriksen; Yonghao Ni; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The objective of this thesis is to determine possible causes of the darkening of hydrogen peroxide bleached mechanical pulp over the visible spectrum and their relative contributions. It focuses on both process conditions and the composition of the pulp and the dilution water, including additions or losses of material along the process line from the bleach tower to the paper machine.

6. 19. Interface-Assisted Perovskite Modulations for High-Performance Light-Emitting Diodes

   Author : Chaoyang Kuang; Feng Gao; Sai Bai; Niclas Solin; Olle Inganäs; Mingjian Yuan; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metal halide perovskite; Light-emitting diodes; Deprotonation; Interfacial reaction; Additive; Molecular interactions; Metall-halid-perovskiter; Lysdioder; Deprotonering; Gränsytegenererade reaktion; Tillsatsämnen; Molekylära interaktioner;

   Abstract : Metal halide perovskites have emerged as a class of promising materials for a wide range of optoelectronic devices. Compared with traditional inorganic and organic semiconductors, perovskite materials can be easily processed via solution-based techniques at low temperatures and exhibit high photo-luminescence efficiency, outstanding colour purity, and superior charge transport properties, showing great promise for cost-effective and high-performance light-emitting diodes (LEDs).

7. 20. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers

   Author : Giovanna Iannuzzi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PP; surface defects; flow marks tiger stripes ; ageing; Injection moulding; ABS; rheological properties; degradation; surface topography; discolouration;

   Abstract : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. READ MORE
