11. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling
Sammanfattning : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. LÄS MER
12. Novel Solid Phase Extraction and Mass Spectrometry Approaches to Multicomponent Analyses in Complex Matrices
Sammanfattning : Analysis of compounds present in complex matrices is always a challenge, which can be partly overcome by applying various sample preparation techniques prior to detection. Ideally, the extraction techniques should be as selective as possible, to minimize the concentration of interfering substances. LÄS MER
13. Disordered eating in a community sample of Swedish adolescent girls
Sammanfattning : Previous research has described that disordered eating (DE) is common in adolescents, especially in girls. DE is defined as maladaptive behaviours (e.g., vomiting) and negative attitudes toward eating and one’s body shape, appearance, and weight. LÄS MER
14. Efficient strategies for collecting posture data using observation and direct measurement
Sammanfattning : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. LÄS MER
15. Sample Efficient Bayesian Reinforcement Learning
Sammanfattning : Artificial Intelligence (AI) has been an active field of research for over a century now. The research field of AI may be grouped into various tasks that are expected from an intelligent agent; two major ones being learning & inference and planning . LÄS MER
