We present and discuss new determinations of metallicity, rotation, age,kinematics, and Galactic orbits for a complete, magnitude-limited, andkinematically unbiased sample of 16 682 nearby F and G dwarf stars. Our∼63 000 new, accurate radial-velocity observations for nearly 13 500stars allow identification of most of the binary stars in the sampleand, together with published uvbyβ photometry, Hipp

Denna uppsats handlar om den delen av kvinnorörelsens historia där kvinnors rätt till högre statstjänster berörs. I takt med industrialiseringen förändrades det svenska samhället och medförde att kvinnor tog plats på arbetsmarknaden på ett helt annat sätt än tidigare. Sedan mitten av 1800-talet var kvinnor aktiva på den statliga arbetsmarknaden och fick tillträde till universitetsstudier i början This essay is about the part of the history of the women's movement where women's right to higher civil service is affected. In time as the industrialization happened, Swedish society changed which resulted in that women took their place in the labor market in a completely different way than before. Since the middle of the 19th century, women were active in the state labor market and gaine

Hjärttransplantationer syftar till att rädda liv men kan även vara riskabla ingrepp. Det är mycket som kan gå fel. Det transplanterade hjärtat lider stor risk att avstötas i mottagarens kropp, och en mer detaljerad kunskap om faktorerna som påverkar avstötning har således möjligheten att rädda liv. Avstötning orsakas av att mottagarens immunförsvar känner av HLA-molekylerna, där HLA står för HumThe beneficial effects of HLA matching at the HLA-A, -B and -DR loci on recipient short- and long-term survival in heart transplants have been established in a number of studies. The objective of the present study was to evaluate the importance of individual HLA alleles at the HLA-A, -B and -DR loci as risk factors for recipient death within one year after transplant by using artificial neural net

Galactic Archaeology is the study of the formation and evolution of the Milky Way through the properties of stars and stellar populations. The combination of stellar ages, chemical compositions, positions, and velocities can reveal the history of star formation and chemical enrichment in different regions of the Galaxy. A large number of stellar spectroscopic, photometric, and astrometric surveys

Context. We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Public Spectroscopic Survey in the years 2012 to 2019. The Gaia-ESO Survey is one among several current and future stellar spectroscopic surveys producing abundances for Milky-Way stars on an industrial scale. Aims. We present an unprecedented effort to cre

Det finns åtta planeter i bana runt vår egen stjärna Solen och flera dvärgplaneter. Astronomer har numera upptäckt avlägsna exoplaneter kretsande runt andra stjärnor i vår galax Vintergatan. Här lyfter vi blicken upp och beundrar nattens alla stjärnor och stjärnbilder och följer astronomerna på deras upptäcktsfärd bland avlägsna exoplaneter.Orbiting our star, the Sun, there are eight planets and several dwarf planets. Astronomers have now discovered planets orbiting several nearby stars in our galaxy, the Milky Way. In this planetarium show we look up into the starry night sky, familiarize ourselves with the stars and the constellations, and together we discover the exoplanets out there and how they can be detected.

Societal outreach and impact “As a researcher I have focused on how the green transition and the worldwide push towards less carbon intensive energy affects local communities. In my work, I have prioritized the voice and situated knowledge of the people who are directly affected by the industrial energy buildout of facilities and gas pipelines necessary for hydraulic fracturing” / Martina Angela C

This invention provides a method for protein structure alignment. More particularly, the present invention provides a method for identification, classification and prediction of protein structures. The present invention involves two key ingredients. First, an energy or cost function formulation of the problem simultaneously in terms of binary (Potts) assignment variables and real-valued atomic coo

We present a general method, the δ-test, which establishes functional dependencies given a sequence of measurements. The approach is based on calculating conditional probabilities from vector component distances. Imposing the requirement of continuity of the underlying function, the obtained values of the conditional probabilities carry information on the embedding dimension and variable dependenc

We develop a new elementary move for simulations of polymer chains in torsion angle space. The method is flexible and easy to implement. Tentative updates are drawn from a (conformation-dependent) Gaussian distribution that favors approximately local deformations of the chain. The degree of bias is controlled by a parameter b. The method is tested on a reduced model protein with 54 amino acids and

Recent advances in experimental plant biology have led to an increased potential to investigate plant development at a systems level. The emerging research field of Computational Morphodynamics has the aim to lead this development by combining dynamic spatial experimental data with computational models of molecular networks, growth, and mechanics in a multicellular context. The increased number of

Popular Abstract in Swedish Denna avhandling baseras på fenomenologiska förutsägelser för högenergetiska partikelkollisioner från två olika teoretiska modeller. De två första artiklarna handlar om osäkerheter i exklusiva reaktioner av typen proton + proton -> proton + proton + Higgs. De fyra andra artiklarna behandlar gravitationell spriding och produktion av svarta hål i modeller med stora extrThis thesis is based on phenomenological predictions for high energy particle collisions from two different theoretical models. The first two papers deal with uncertainties in exclusive reactions of type proton + proton -> proton + proton + Higgs. The other four papers concern gravitational scattering and black hole production in the scenario of large extra dimensions.

We deal with some halos generated by the divergent light from a nearby source. After discussing how the divergent light transforms some halo features, we give an outline of a method of handling the simulation of a divergent-light halo. The simulation method is then successfully tested on some well-documented halo observations. We also present a "simulation atlas" that shows halos produced by cryst

Experimental and theoretical studies of lifetimes and transition probabilities for doubly ionized mercury, Hg III, are reported. Such data are currently of great astrophysical interest because observations with the Goddard high resolution spectrograph on board the Hubble space telescope have shown some 5d(9)6s-5d(9)6p transitions of Hg III in the spectrum of the chemically peculiar star chi Lupi.

The main purpose of this thesis is to present and analyse the Swedish sixteenth-century Catholic priest Andreas Servius’ prayer book Någre Christilige och Catholische böner printed in the Silesian city of Neisse year 1593. The general questions of the study are: which where the main sources of the prayers found in this prayer book? What characteristics typical for the period’s piety can be found i

When it comes to reading, there are rather large differences between boys and girls in skill and frequency, and these differences have persisted for decades. For the last few years I have sensed an increasingly negative image of boys and men in the ”public conversation”. What to read is a matter of personal choice, yet this personal choice is, in this conversation, connected to war, men’s violence

Nukleosynthes i ackretionsskrivor kring svarta hål. Hur bildas atomerna som bygger upp oss människor - till exempel atomer av kol, syre eller kalcium? Den idag gâllande teorin är att lättare atomer såsom väte, helium och litium skapades vid "Big Bang", medan en supernova från en döende stjärna producerade och frigjorde bland annat kol, syre, kalcium och järn. Det som stjärnnor och Big BNucleosynthesis is the mechanism which produces new elements in nuclear reactions. Nuclear reaction rates are highly temperature dependant, and nuclear reactions take place in very hot environments. Current theories predict that the light elements such as hydrogen and helium were produced during the Big Bang. On the other hand, the core of stars produce heavier elements through nuclear fusion. The

In this thesis, a Glauber Monte-Carlo event generator is developed and used to analyze proton-Ion (p -$^{63}$Cu and p -$^{197}$Au) and Ion-Ion ($^{63}$Cu -$^{63}$Cu and $^{197}$Au -$^{197}$Au) collisions. Three different sub-collision models are implemented, the black disk, grey disk and oscillating grey disk models, and their validity is compared. The predicted nucleon-nucleon cross-sections by t

Understanding cell-fate decisions in stem cell populations is a major goal of modern biology. Stem and progenitor cell populations are often heterogeneous, which may reflect stem cell subsets that express subtly different properties, including different propensities for lineage selection upon differentiation, yet remain able to interconvert. We discuss these properties with examples both from the
