We have derived elemental abundances of O, Na, Mg, Al, Si, Ca, Ti, Cr, Mn, Fe, Co, Ni as well as for a number of s-elements for 47 G and K dwarf, with [Me/H]>0.1 dex. The selection of stars was based on their kinematics as well as on their uvby-beta photometry. One sample of stars on rather eccentric orbits traces the chemical evolution interior to the solar orbit and another, on circular orbits,
Popular Abstract in Swedish Konflikter och sexuellt urval under pollenkonkurrens Naturens många fantastiska färger och former har till stor del skapats av det sexuella urvalet, det vill säga selektionstryck som skapas av konkurrens och val, som uppstår till följd av att djur och växter fortplantar sig. Det var Darwin som 1871 presenterade teorin om det sexuella urvalet i ett försök att förklara vThe incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. Using the hermaphroditic annual herb Collinsia heterophylla, I looked deeper into the role of pollen-pollen comp
For the 2012 Pedagogical Inspiration Conference for teachers at the Faculties of Humanities and Theology at Lund University, my course team and I presented a paper entitled “Interdisciplinarity, group responsibility and conflict as resources for learning”. The paper discussed our experiences with The City: Boundary Transgressions and Visual Expressions (KOVR02), an interdisciplinary course given i
In 1949, Swedish actress Ingrid Bergman caused a well known scandal in Hollywood by leaving her Swedish husband Petter Lindström and their daughter for Italian film director Roberto Rossellini. The effects of this scandal in America have been thoroughly described in works like Bergman’s autobiography (Bergman, 1980), Donald Spoto’s recent biography on Bergman (Spoto, 1997) and in specialized schol
We document the impact of blood parasite infections caused by Hepatozoon sp. on water python (Liasis fuscus) life history traits such as growth rates, condition, reproductive output and survival. Individual snakes maintained similar among-year parasite loads. Hepatozoon infections affected python growth rate, i.e. snakes suffering from high infection levels exhibited significantly slower growth co
Background. The conventional treatment for poststernotomy mediastinitis usually involves surgical revision, closed irrigation, or reconstruction with omentum or pectoral muscle flaps. Recently, vacuum-assisted closure has been successfully used in poststernotomy mediastinitis. The aim of the present study was to compare the clinical outcome and survival in 101 patients undergoing vacuum-assisted c
The performance of poly(1-trimethylsilyl-1-propyne) (PTMSP)/silica nanocomposites was studied for membranes with a filler content between 0 and 50 wt%. An increase in permeability and a decrease in vapor selectivity was measured with increasing filler content. The free volume sizes and interstitial mesopore sizes of the composites were determined by use of positron annihilation lifetime spectrosco
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances from the NH band at 336 nm in 35 extremely metal-poor halo giants, with carbon and oxygen abundances from Cayrel et al. (2004, A&A, 416, 1117), using high-quality ESO VLT/UVES spectra (30 of our 35 stars are in the range -4.1 <[Fe/H] < -2.7 and 22 stars have [Fe/H] < -3.0). N abundance
Popular Abstract in Swedish Kritiskt sjuka patienter på intensivvårdsavdelningar (IVA) har ofta störningar i blodets levringsförmåga (koagulation). Kliniska tecken som blodpropp (djup ventrombos eller blodpropp i lungorna) och/eller blödning kan vara resultatet av aktivering och konsumtion av koagulationsfaktorer och koagulationshämmare. Disseminerad intravaskulär koagulation (DIC, som är en samtiCritically ill patients in intensive care units (ICU) often have coagulation disturbances. Clinical manifestations such as thromboembolism and/or bleeding may result from activation and consumption of coagulation factors and inhibitors. Disseminated intravascular coagulation (DIC) is a severe condition with an often-poor prognosis. Global haemostatic tests are inexpensive, widely available, and ma
During 1956 through 1987, 96,891 children have been screened for neonatal hip instability according to the tests of Ortolani and Barlow. In 1956 through 1972 only 4/58, 759 (0.07 permille) were missed, whereas during 1980 through 1987, 12/19, 398 (0.6 permille) were missed. This increase is not caused by any formal alteration of the screening programme. The screening has prevented a late diagnosis
Here we investigated whether microwaves (MWs) of Global System for Mobile Communication (GSM) induce changes in chromatin conformation in human lymphocytes. Effects of MWs were studied at different frequencies in the range of 895-915 MHz in experiments with lymphocytes from seven healthy persons. Exposure was performed in transverse electromagnetic transmission line cell (TEM-cell) using a GSM tes
We measured angular distributions of differential cross section, beam analyzing power, and recoil polarization for neutral pion electroproduction at Q(2)=1.0 (GeV/c)(2) in 10 bins of 1.17 <= W <= 1.35 GeV across the Delta resonance. A total of 16 independent response functions were extracted, of which 12 were observed for the first time. Comparisons with recent model calculations show that respons
Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. Three public transport systems are focused, service route traffic, trunk route traffic and special transport service, which demand different capa
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
More than 50 years ago, Fish postulated that a special form of early abnormal neurodevelopment, "pandysmaturation", defined a priori as constituting retarded cranial development in the first year of life, combined with delay in early motor milestone attainment, was related to genetic risk for schizophrenia, and was associated with schizophrenia-spectrum disorders in young adulthood. Fish confirmed
Hemophilia patients with inhibitors against FVIII/FIX present with a major challenge in the clinical practice. In the 1970s such patients were treated in association with emergency situations and essential surgery using huge amounts of FVIII/FIX concentrates often preceded by extracorporal adsorption of antibodies against FVIII/FIX. However, moderate to mild bleedings were not effectively treated.
Heterocyclic amines (HAs), formed when meat and fish are cooked at high temperatures, have been linked to mammary gland cancer in rats, and some epidemiological studies indicate increased breast cancer risk by consumption of well-done meat. The epidemiological evidence linking HAs per se to breast cancer is however sparse, especially from prospective studies. Moreover, high-fat diets rich in omega
There is a class of oligodendrocyte progenitors, called O-2A progenitors, that is characterized by expression of platelet-derived growth factor &agr;-receptors (PDGFR(&agr;)). It is not known whether all oligodendrocytes are derived from these PDGFRalpha-progenitors or whether a subset(s) of oligodendrocytes develops from a different, PDGFR alpha-negative lineage(s). We investigated the re
In order to reduce the environmental impacts within the building sector, recycling of building materials is on the increase. Projects are carried out on several levels and are often well analysed regarding the economic consequences; however, the actual environmental effects are rarely studied. This paper presents a study of the environmental impacts due to a building from 1997 with a large proport
During my thirty years in the academic field I have always been interested in biographical studies. The focus has been on significant experiences in the individual’s life, so-called turning points, peak experiences or other decisive and unforgettable moments. Was there a crisis of some kind? And, if this is the case,how did the person in question cope with this low point in his or her life? I lear
