1. 1. 3D Electron Diffraction : Application and Development towards High-quality Structure Determination

   Författare :Yunchen Wang; Wei Wan; Xiaodong Zou; Junliang Sun; Mauro Gemmi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; three-dimensional electron diffraction; structure determination; rotation electron diffraction; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Electron crystallography has been proven to be effective for structure determination of nano- and micron-sized crystals. In the past few years, 3D electron diffraction (3DED) techniques were used for the structure solution of various types of complex structures such as zeolites, metal-organic frameworks (MOF) and pharmaceutical compounds.

3. 2. Aquaporins - Novel approaches to old problems

   Författare :Carl Johan Hagströmer; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporin AQP ; membrane proteins; X-ray crystallography; nephrogenic diabetes insipidus; Sjögren s syndrome; cataracts; ezrin; calmodulin; continuous diffraction; protein-protein interactions;

   Sammanfattning : As all life on this planet evolves around water, it is important for our bodies to be able to regulate it. This may be done passively, but just like with water in the ocean, if we were to rely solely on passive transport (such as evaporation), the flow of water would be too slow for biological functions to uphold the homeostasis that is so important for us to survive.

4. 3. Environmental Monitoring - using diode-laser-based spectroscopic techniques

   Författare :Gabriel Somesfalean; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diode-laser spectroscopy; frequency-modulation spectroscopy; frequency conversion; diffraction; scattering; Electromagnetism; acoustics; akustik; optik; absorption spectroscopy; Elektromagnetism; optics; Fysicumarkivet A:2004:Somesfalean;

   Sammanfattning : Monitoring of environmental gases is necessary to understand the complex processes governing global warming and the impact of pollutant emissions related to human activity. Diode-laser-based spectroscopic techniques, being robust and affordable, have a great potential to become an industrially well-established technology for environmental sensing. LÄS MER

5. 4. Unwrapping Cobol : Lessons in Crisis Computing

   Författare :Linda Hilfling Ritasdatter; Susan Kozel; Maria Hellström Reimer; Florian Cramer; Nishant Shah; Malmö universitet; []
   Nyckelord :Crisis; Execution; Maintenance; Cobol; Automation; Global Flows; Y2K; Human Factor; Outsourcing; Development; Legacy Systems; Programming Languages; History of Computing; HCI; Software Wrapping; Postcolonial Studies; Diffraction; Broken world thinking; Grace Hopper; Media Archaeology; Debugging; Zombie Media; Obsolescence; Technological Development; Unsettling Ontologies; Fourth Industrial Revolution; Artificial Intelligence; Interaktionsdesign; Interaktionsdesign;

   Sammanfattning : By engaging with COBOL, a detested and would-be obsolete programming language, the dark sides of automation are examined in this thesis: hidden workforces and computational infrastructures that are, in reality, central to the execution and maintenance of global economic and informational flows. Frictions within these flows are made more visible in moments of crisis when asymmetrical power structures are surfaced, as demonstrated in an analysis of the infamous Y2K Bug, its connection to the outsourcing boom in India and the legacy of COBOL.

7. 5. Characterization of Pathfinders and Indicators of Gold

   Författare :Gabriel Kofi Nzulu; Martin Magnuson; Per Eklund; Hans Högberg; Farid Akhtar; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pathfinder; Indicator; Gold; Hydrothermal; X-ray; Diffraction; Kubi; Ghana;

   Sammanfattning : Research on natural minerals and their chemical bonding to economically critical raw materials is a viable industrially relevant research area due to its increasing demand. Meeting demands requires fast, robust, and efficient techniques to explore new ore deposits and continuous operation of active mines as well as recycling. LÄS MER
