Between 1970 and 1995, well over 200 directives dealing with environmental problems have been adopted by the European Community. The ambition in this study has been to understand the process whereby environmental concerns have been brought up on the Community agenda and how that agenda has subsequently been shaped. It is argued that by starting from a critical position in ecocentric and feminist t
Aims: The increasing number of people on disability pension in Sweden is of concern for Swedish policy-makers, and there is a need for a better understanding of the mechanisms behind disability pension. We investigated ( i) whether women living in the same neighborhood have a similar propensity for disability pension that relates to neighborhood social participation, and ( ii) whether there is an
Accurate chronologies are essential for linking palaeoclimate archives. Carbon-14 wiggle-match dating was used to produce an accurate chronology for part of an early Holocene peat sequence from the Borchert (The Netherlands). Following the Younger Dryas-Preboreal transition, two climatic shifts could be inferred. Around 11 400 cal. yr BP the expansion of birch (Betula) forest was interrupted by a
Popular Abstract in Swedish Avhandlingen handlar om ett område i hjärnan som kallas amygdala. Detta området är ansvarigt för att lära sig vad man bör tycka om och vad man skall vara rädd för. I avhandlingen diskuteras hur det här området verkar fungera, och hur det arbetar tillsammans med andra områden för att göra sitt jobb. Dessa reaktioner är primitiva känslor; rädsla, lycka och så vidare. AvhaThe amygdala is a small subcortical structure that has long been implicated in the conditioning of fear and other emotions. It is heavily interconnected to a number of both cortical and subcortical structures and is thus well placed to integrate sensory inputs from multiple areas to produce emotional reactions directly as well as influence learning and attention systems. Data suggests that the amy
High-spin states of the mass A = 39 mirror pair K-39 and Ca-39 were investigated via the fusion-evaporation reaction Si-28+O-16 at 125 MeV beam energy. The GAMMASPHERE array in conjunction with the 4 pi charged-particle detector array MICROBALL and neutron detectors was used to detect gamma rays in coincidence with evaporated light particles. The results of the first high-spin study of the T-z = -
Let c(x) = inf {t > 0: Q(t) greater than or equal to x} be the time of first overflow of a queueing process 1001 over level x (the buffer size) and Z = P(T(X) less than or equal to T). Assuming that {Q(t)) is the reflected version of a Levy process {X(t)} or a Markov additive process, we study a variety of algorithms for estimating z by simulation when the event {tau(X) less than or equal to T} is
The solubility of tri-n-octylamine (TOA) in water and phosphoric acid is reported. Equilibration is achieved by circulating the solutioin through PVC pieces saturated with the absorbed amine in a glass tube. The dissolved TOA is determined by capillary gas chromatography which can detect amine concentrations down to 10 μg l−1. The solubility of TOA in water is 0.039 mg l−1 and in 5.5 M phosphoric
Source-sorted municipal organic waste collected from different dwelling types in five Danish cities and pre-treated at three different plants was sampled and characterized several times during one year to investigate the origin of any differences in composition of the pre-treated waste introduced by city, pre-treatment technology, dwelling type or annual season. The investigated pre-treatment tech
How can tools help structure tasks to make them cognitively easier to perform? How do artefacts, and our strategies for using them, develop over time in cognitively beneficial ways? These are two of the main questions that are explored in the five papers collected in this thesis. The first paper details an ethnographic study conducted on people cooking in their homes. The study is a first pass ov
Co(II) adsorption at ZnO- and ZnS-aqueous interfaces was studied with the XAFS technique. The results show the presence of both 4- and 6-coordinated oxygen-ligated Co(II) on ZnO, corresponding to Co-O distances of 1.95 and 2.1 Angstrom, respectively. At ZnS two Co-O distances are also indicated and a Co-S correlation at 2.36 Angstrom is revealed. Higher shell analysis indicates a fraction of biden
We have analysed 994 sites for oncogenes and tumour suppressor genes located within human chromosome bands. The data presented disclose that: 1) These cancer genes build ridges as well as hot spots, which are not related to the position of other types of genes present in these chromosomes. 2) The frequency of cancer genes is not directly related to chromosome length, to the number of DNA bases per
Background: In obese patients, jejunoileal bypass (JIB) has been used to induce weight reduction. Changes in the neuroendocrine system may be affected by the JIB-operation, because the proximal small intestinal mucosa has a rich supply of endocrine cells and peptidergic nerves. Materials and Methods: In 37 obese patients operated with JIB 1-30 years ago, small intestinal biopsies were taken at the
This paper investigates the L2 acquisition of clausal syntax in post-puberty learners of German and Swedish regarding V2, VP headedness and verb particle constructions. The learner data are tested against L2 theories according to which lower structural projections (VP) are acquired before higher functional projections (IP, CP), VP syntax is unproblematic (invulnerable), but where grammatical opera
The missed opportunity cost (MOC), i.e., all foregone alternatives while foraging in a patch, is an important aspect of the cost-benefit analysis of foraging patch use. When making between-environment comparisons it will often be the most important factor influencing behavior, but it has received less interest than other foraging costs. In this paper, we focus on differences between individuals li
The passerine major histocompatibility complex (MHC) class I and IIB genes are different from those of the avian model species the chicken because passerines have (1) a larger number of MHC genes, (2) MHC genes with longer introns, and (3) MHC genes that are pseudo-genes. Most passerine MHC genes are transcribed (coding), extremely variable and subject to balancing selection. The high genetic dive
Cationic surfactants associate strongly to DNA and compact but are often toxic. The interaction of some novel cationic amino acid-based surfactants, which may enhance transfection and appear to be nontoxic, is described. A cationic arginine-based surfactant, ALA, gives in combination with anionic surfactants spontaneously stable vesicles, and special attention is given to the association of these
Popular Abstract in Swedish Avhandlingen undersöker den teoretiska bakgrund och den forskningskontext inom vilken tolkningar av den Nordiska bronsåldern har formats. Avhandlingens teoretiska analys betonar teorier om social praxis och fenomenologiska perspektiv. Analysens syfte är att undersöka hur teorierna kan användas som verktyg för att förstå den dynamiska relationen mellan bronsålderns materThe thesis investigates the theoretical background and the research context within which interpretations of the Nordic Bronze Age have been formed in Scandinavian archaeology. A theoretical analysis that emphasises theories of social practice and phenomenological perspectives is presented. The purpose of the analysis is to explore theories of social practice as tools for grasping the dynamic relat
Lifetimes of high spin states in the three A = 89 isobars Nb-89, (89)MO and (TC)-T-89 have been measured via the Recoil Distance Doppler Shift technique and the fusion evaporation reactions Ni-58(Cl-35, xnypz alpha) at 120 MeV beam energy. Reduced transition probabilities for about 50 gamma transitions were extracted. The experimental branching ratios in Mo-89 and reduced transition probabilities
