Oroande trend för svenska blåhakar Blåhakern är en karaktärsart i svenska fjällen och de flesta vandrare med öra för fågelsång har nog hört denna häpnadsväckande fågel sjunga bland fjällbjörkar eller på fjällheden. Studier från bl a Finland har visat att nordliga långflyttare såsom blåhaken har visat sig särskild sårbara för effekter av den pågående klimatförändringen. Tundran, däribland de svensArctic ecosystems are among the most vulnerable to climate warming due to large-scale changes in temperature, followed by altered community structure. Northern birds are subject to population reduction and range contraction in Europe and many mountainous birds show negative trends. Even if global trends are clear, local studies on a detailed level are needed to obtain more information on possible

State-of-the-art multiconfiguration Dirac-Hartree-Fock calculations for Te V have been performed and energies, LS-compositions, radiative lifetimes and Lande gJ-factors for 51 odd and even parity states are presented. In addition, predictions on transition rates and oscillator strengths for a multitude of transitions between these states are reported for the first time. To describe the atomic syst

Att undersöka stjärnor i infrarött är en relativt ny företeelse till skillnad från optisk astronomi (dvs. synligt ljus). Det var först på 60-talet med teleskopet Stratoscope II som man lyckades få spektra från stjärnor i infrarött (våglängder på runt 3 m), och upptäckte förekomsten av vatten i kalla röda jättar. Den bakomliggade problematiken till varför modern infraröd astronomi är så ungt är våThe advent of infrared astronomy, unlike optical astronomy that was developed over centuries, was delayed until the space age due to our own atmosphere acting as an efficient shield towards this radiation. With a lot of molecules (including water) emitting in the infrared region, it was first in the late 1990s that water no longer was deemed special and was observed in many cooler (K-M) giant star

Evolution is a fundamental and crucial part of life that hinges on two central properties: robustness and evolvability. Robustness is required to maintain essential traits despite mutations while evolvability produces novel traits that might prove beneficial in survival. While both robustness and evolvability are necessary, embracing them simultaneously seemingly leads to an inherent conflict due

Människans nyfikenhet när det gäller vårt Universum är närmast oändlig. I tusentals år har vi tittat uppåt och undrat om himlen helt enkelt är gudarnas domän eller om det kan finns varelser där ute i oändligheten som liknar oss.I denna visning reser vi från Jorden ut genom vårt Solsystem, besöker Solen och de åtta planeter som kretsar runt den, innan vi åker vidare mot stjärnor och galaxer. GalaxeIn this show we travel from the Earth to the edge of the Universe, discovering planets, stars and galaxies along the way.

A study on a possible solar wind interaction with the North AtlanticOscillation (NAO) is performed. Results are presented suggesting arelationship between the NAO index and the electric field strength E ofthe solar wind. A possible scenario for the suggested interaction isthat an electromagnetic disturbance is generated by the solar wind inthe global electric circuit of the ionosphere. This distur

Syftet med denna uppsats är att undersöka om Sverige har uppfyllt sina internationella åtaganden gällande efterlevnaden av principen om non-refoulement i svensk migrationsrätt. I generella termer innebär principen om non-refoulement ett verkställighetshinder mot avvisning och utvisning då personen i fråga riskerar att utsättas för tortyr och förföljelse i det mottagande landet. Denna princip kommeThe purpose of this thesis is to assess whether Sweden has fulfilled its obligation to implement the principle of non-refoulement in Swedish migration law. The principle of non-refoulement, in general terms, implies an impediment for execution that obliges a state not to permit removal of a person to a county where he or she is at risk of being subjected to torture or persecution. This principle i

This article is over 5 years old, and the information may therefore be outdated. - Sustainability is often studied from a large-scale, political or institutional perspective. I was interested in looking at sustainability from the other end, how individual inner transition could impact on global sustainability, says Professor Christine Wamsler from LUCSUS.This interest led her to conduct a study on

In proteomics, rapid developments in instrumentation led to the acquisition of increasingly large data sets. Correspondingly, ProDaC was founded in 2006 as a Coordination Action project within the 6th European Union Framework Programme to support data sharing and community-wide data collection. The objectives of ProDaC were the development of documentation and storage standards, setup of a standar

A deterministic algorithm for calculating polymer properties is presented. It is based on a variational approach where the bond and Coulomb potentials are approximated by a quadratic trial energy. The parameters which describe average atom positions and Gaussian fluctuations, are the solutions of matrix equations. By a judicious choice of parameter representations and the use of incremental matrix

Using a simple hydrophobic/polar protein model, we perform a Monte Carlo study of the thermodynamics and kinetics of binding to a target structure for two closely related sequences, one of which has a unique folded state while the other is unstructured. We obtain significant differences in their binding behavior. The stable sequence has rigid docking as its preferred binding mode, while the unstru

We present novel rope hadronization results for strange hadron enhancement in pp, pPb, and PbPb collisions using PYTHIA/Angantyr at LHC energies. With the rope model for string fragmentation, we find that the strangeness and baryon enhancement has a coherent increase across all collision systems as a function of average charged central multiplicity, in qualitative agreement with LHC data. In AA co

För bakterier kostar det energi och tid att ha oanvändbart genetiskt material, och det är dessutom i vägen i en redan trång cell. Därför bör man göra sig av med onödigt material. Men på samma sätt som man tror sig snart kunna komma att behöva de sakerna som så länge stått och ”samlat damm i garderoben”, så är akterier ovilliga att kasta bort fullt fungerande gener. Dessa gener samlar de i så kallaPlasmids are circular DNA molecules found in bacteria. These molecules often contain genes coding for resilience against harmful substances such as antibiotics, in its environment. To be able to classify plasmids fast, and with small samples would be of great gain for medical care, to improve the efficiency of treatments, and to reduce the spread of antibiotics resistance. Our experimental collab

This talk presents some results relevant for lattice QCD at higher order in ChPT. First we discuss the finite volume corrections at two loops for the quark condensate as well as a Luscherlike finite volume formula for it. The latter allows for an alternative determination of meson sigma terms. The second set of results presented here are the calculations at two loops in partially quenched chiral p

Using an atomic model with a simplified-sequence-based potential, the folding properties of several different peptides are studied. Both alpha-helical (Trp cage, F-s) and beta-sheet(GB1p, GB1m2, GB1m3, Betanova, LLM) peptides are considered. The model is able to fold these different peptides for one and the same choice of;parameters, and the melting behaviour of the peptides (folded population aga
