Popular Abstract in Swedish Vår galax, Vintergatan, är en spiralgalax som innehåller bortåt 200 miljarder stjärnor. En mörk natt kan man urskilja ca 3000 av dessa på himlavalvet. Tittar man noggrant så kan man också se ett diffust ljusband som sträcker sig genom, bland andra, stjärnbilderna Skytten och Cassiopeia. Detta diffusa band är det samlade ljuset från alla de miljarder stjärnor i VintergatThe origin and evolution of the thin and thick disks in the Galaxy have been studied by means of detailed stellar abundances. High-resolution spectra of 102 F and G dwarf stars have been obtained with the spectrographs on the ESO 3.6-m and ESO 1.5-m telescopes on La Silla (Chile), the Very Large Telescope (VLT) on Paranal (Chile), and the Nordic Optical Telescope (NOT) on La Palma (Canary Islands,

Popular Abstract in Swedish Förmågan att kunna hitta mat är väldigt viktigt för alla djur eftersom detta påverkar flera saker, t ex hur snabbt man växer. Det i sin tur påverkar vilken roll man har i en grupp, hur mycket energi man har råd att lägga på fortplantning och hur många ungar man får. Att söka mat är oftast för-knippat med att äta, men inkluderar även andra aspekter som att söka efter matThe foraging ability of an organism is essential since it affects various traits, e.g. growth, reproduction effort, social status and, ultimately, fitness. Foraging is often associated with food intake but includes more aspects such as searching for and assessing food patches and evaluating the patch as good or bad compared to the rest of the environment. On top of that, a forager also has to surv

Wetland creation at large, regional scales is implemented as a measure to abate the biodiversity loss in agricultural landscapes and the eutrophication of watersheds and coastal areas by non-point source nutrient pollution (mainly nitrogen). The consequences of creating many new wetlands for biodiversity conservation and nutrient retention (ecosystem functioning) in agricultural landscapes are sti

We studied the foraging technique of Ospreys Pandion haliaetus during different wind speed conditions at Lake Hammarsjon, Sweden in autumn 2003. Different fishing techniques were used with a shift in relation to wind speed: (1) without hovering, (2) hovering with pure flapping flight, (3) hovering with flapping flight and gliding into the wind, and (4) hovering with pure gliding. The results suppo

Aim: To describe differences and similarities between reported and non-reported data in the Swedish Cardiac Arrest Register in selected parts in Sweden. Methods: Prospective and retrospective data for treated OHCA patients in Sweden, 2008-2010, were compared in the Swedish Cardiac Arrest Register. Data were investigated in three Swedish counties, which represented one third of the population. The

T cells are key cellular components of the adaptive immune system that play a critical role in our defense against pathogens and cancer but also contribute to pathology in the setting of chronic inflammation and autoimmunity. The thymus constitutes the body's major T cell production site, where bone marrow-derived progenitors migrate in a co-ordinated fashion through anatomically distinct cortical

Former research indicates that the crack width close to the bar can be a better indicator for the risk for reinforcement corrosion than, as current concrete codes impose, the crack width at the concrete surface. In this paper a finite-element model is used to increase the understanding of how the crack width varies at different levels from the reinforcement and how different mechanisms control thi

Karst är landskap och karakteristika som är viktiga både ur hydrologisk och geologisk synpunkt och som är utvecklade genom vattnets vittring av oftast karbonathaltiga stenar. Denna uppsats kartlägger världens karstområden, beskriver egenskaper av karst och karsthydrologi och strävar efter att definiera problem och möjligheter med vattenhantering i karstlandskap. Akvifärer i karst skiljer sig i månSummary: Water is, and will in the near future be even more, a key issue for the global development, and for issues concerning equal rigts for all mankind. Water is a necessity and a scarce resource in great parts of the world and it therefore exists a great need for development and management of the world’s waters. With fresh waters being increasingly accentuated for their importance in global de

The construction sector currently accounts for 41.4% of the total energy consumption in Egypt and the residential sector accounts for more than half of all electricity consumed in the country. Therefore, there is great potential for reducing electricity use. Much of the electricity is used for lighting, air conditioning and hot water, a great part of this use can be reduced by passive climate cont

The thesis work concerns development and application of four versatile nonlinear optical techniques, based on exploiting ultrashort laser pulses, for diagnostic purposes in gases and flames. The four techniques, all laser-based, are two-photon laser-induced fluorescence (TPLIF), hybrid femtosecond/nanosecond (fs/ns) rotational coherent anti-Stokes Raman scattering (fs/ns RCARS), fs-laser-induced g

Background: Neurological injuries are frequent following Acute Type A Aortic Dissection (ATAAD) repair occurring in 4–30% of all patients. Our objective was to study whether S100B can predict neurological injury following ATAAD repair. Methods: This was a single-center, retrospective, observational study. The study included all patients that underwent ATAAD repair at our institution between Jan 19

The digestibility of starch in white wheat bread was studied. Raw wheat starch and raw wheat flour were used as reference materials. The extent of digestion and absorption in vivo was evaluated through balance experiments in rats given test diets with and without addition of the antibiotic, Nebacitin, to reduce the fermentation in the hind-gut. As judged from a high faecal recovery of dietary fibr

Type 1 diabetes (T1D) is an autoimmune disease that targets pancreatic islet beta cells and incorporates genetic and environmental factors1, including complex genetic elements2, patient exposures3 and the gut microbiome4. Viral infections5 and broader gut dysbioses6 have been identified as potential causes or contributing factors; however, human studies have not yet identified microbial compositio
