Fibrillar macromolecules are long, linear structures that have helical symmetry. A technique called X-ray fiber diffraction (XRFD) is often used to help solve the three-dimensional structure of fibrillar macromolecules. Models of fibrillar structure, built de novo, using homologs or using experimental data derived from other methods should be compared to this experimental XRFD data to test and ref

Det pågår ständigt en utveckling för att minska både risker för miljö och hälsa inom den kemiska industrin. Oftast handlar det om att förbättra existerande processer eller att helt enkelt hitta nya vägar till samma produkt och i grunden ligger forskning bakom framgångarna.Polyurethane is a widely used polymer with a lot of different applications due to its versatility and often resilient properties. The polymeris often prepared as a two component system consisting of polyols and isocyanates and can be cured at relatively low temperatures. Even though the formed polymer is hazardless the isocyanate used in the manufacture is dangerous in itself, but even more so is

The Swedish energy policy is guided by two government bills which were approved by the Swedish parliament in 2009 stating that at least 50 percent of the electricity share should be provided by renewable energy sources by 2020. This thesis focuses on the wind power production and it is a part of the Smart Grid Gotland (SGG) project. One of the goals stated by the SGG project is to have an optimal
Betydelsen av en bra stallmiljö för en välmående häst och länsstyrelsens godkännande av stallar för en frisk häst En välmående häst är glad, nyfiken och positiv till arbete. För att hästar ska må bra i stallet är det viktigt att stallmiljön är anpassad efter dem. För att kunna se till att stallet är utformat på ett bra sätt är det nödvändigt att känna till de viktigaste faktorerna i stallmiljön sThis study shows that to establish good horse welfare in the stable the housing conditions need to be carefully considered. Swedish animal welfare legislation imposes requirements of stable and horse owners to act in a certain way to prevent animal suffering. But many owners lack knowledge about why horses have specific requirements of its housing environment and that is why this study is importan
Novel therapeutic strategy for acute myeloid leukemia Acute myeloid leukemia, AML, is a type of blood cancer that is generally common among elder ages with median age of 65 years old. Around 350 cases per year are diagnosed with AML in Sweden. It is characterized by infiltration of cancer cells in the bone marrow leading to insufficient production of different blood cell types including the immu
Spatial data is an important and necessary ingredient in the disaster management cycle. The preparedness phase requires simulation of disastrous events, identification of disaster management hotspots and creation of hazard- and risk maps. A rapid response in the event of a disaster requires good situational awareness and fast sharing of that knowledge across the community. Further, in the recovery
There are competing standards regarding the definition of the crime of “enforced disappearance” under international law. When criminalizing enforced disappearance at the national level as part of their obligations under international law, States which adopt a more narrow definition of enforced disappearance provided in the Rome Statute require victims of enforced disappearance to prove the existen
Höksångarens Sylvia nisoria flyttning och övervintring Fåglars flyttning har fascinerat forskare under en lång tid. Från att ha varit begränsat till visuella observationer har utvecklingen tagit forskningsfältet framåt via bland annat ringmärkning, radar, satellit- och GPS-sändare. Det senaste decenniet har mycket små ljusmätande apparater gjort det möjligt att detaljerat följa även mindre fåglarTechnological advancements in the past few decades have been pushing the research field of animal migration forward rapidly.
