Potential effects of climate change on plant species in the Faroe Islands

Aim To identify the effect of climate change on selected plant species representative of the main vegetation types in the Faroe Islands. Due to a possible weakening of the North Atlantic Current, it is difficult to predict whether the climate in the Faroe Islands will be warmer or colder as a result of global warming. Therefore, two scenarios are proposed. The first scenario assumes an increase in

Myosin composition and functional properties of smooth muscle from the uterus of pregnant and non-pregnant rats

The myosin heavy chain stoichiometry and the force-velocity relation have been determined in the myometrium of the non-pregnant and pregnant rat. The relative proportions of the slower migrating heavy chain (MHC1) greatly exceeded that of the faster migrating heavy chain (MHC2) as shown by electrophoresis on SDS 4%-polyacrylamide gels. The ratios of MHC1/MHC2 were 2.2/1 in the non-pregnant rats, 2

The contact system-a novel branch of innate immunity generating antibacterial peptides.

Activation of the contact system has two classical consequences: initiation of the intrinsic pathway of coagulation, and cleavage of high molecular weight kininogen (HK) leading to the release of bradykinin, a potent proinflammatory peptide. In human plasma, activation of the contact system at the surface of significant bacterial pathogens was found to result in further HK processing and bacterial

Cleaning of ultrafiltration membranes after treatment of oily waste water

The influences of different types of cleaning agents on a polysulphone ultrafiltration (UF) membrane which had been used to treat oily waste water were investigated. The cleaning experiments were performed with samples of polysulphone membranes removed from a commercial plant in which oily waste water is treated. Five different cleaning agents were used and their influences on the fluxes were inve

Mitogenic effects of ATP on vascular smooth muscle cells vs. other growth factors and sympathetic cotransmitters

The sympathetic nervous system has been shown to exert a trophic influence on vascular smooth muscle cells (VSMC). Therefore, we studied the growth-regulating effects of the sympathetic cotransmitters ATP, neuropeptide Y (NPY), and norepinephrine (NE). ATP in concentrations of 1-100 microM greatly increased the incorporation of [3H]thymidine in VSMC from rat aorta and vena cava. ATP also increased

Left ventricular heart failure model for testing cardiac assist devices

During the development of a new circulatory support system, we have used different animal models with and without heart failure for hemodynamic testing. As the normally functioning heart does not always allow for proper evaluation of a circulatory support system, a good and adjustable animal heart failure model is needed. The aim of the study was to develop a left ventricular failure model in calv

Animism, fetishism, and objectivism as strategies for knowing (or not knowing) the world

Animistic or 'relational' ontologies encountered in non-Western (i.e. premodern) settings pose a challenge to Western (i.e. modern) knowledge production, as they violate fundamentalassumptions of Cartesian science. Naturalscientists who have tried seriously to incorporate subject-subject relations into their intellectual practice (e.g. Uexküll, Bateson) have inexorably been relegated to the margin

Pain and sensory dysfunction 6 to 12 months after inguinal herniotomy

Inguinal hernia repair is associated with a 5%-30% incidence of chronic pain, but the pathogenesis remains unknown. We therefore evaluated pain and sensory dysfunction by quantitative sensory testing 6-12 mo after open herniorrhaphy. Before sensory testing, all patients (n = 72) completed a short-form McGill Pain Questionnaire and a functional impairment questionnaire. Sensory dysfunction in the i

Ring chromosomes and low-grade gene amplification in an atypical lipomatous tumor with minimal nuclear atypia

Atypical lipomatous tumors (ALTs) are characterized by supernumerary ring chromosomes and/or giant marker chromosomes, which typically are composed of interspersed, amplified 12q-sequences, are C-band negative, lack a-satellite sequences, and display high copy numbers of several oncogenes, including HMGA2 (a.k.a. HMGIC) and MDM2, from the 12q13-15 region. In the present study, we report the cytoge

Abstract in French L'objectif de cette étude exploratoire est de voir si l'utilisation des formes interlangagières du type "je parlE" ou "je veux habite" par des apprenants suédophones adultes du français langue étrangère seraient influencées par la fréquence des formes dans l'input. L'étude est faite à partir de données de production orale (apprenants) et de données du français parlé (input).

Wishing, choosing and wanting. On the decision to have a child

Falling birth rates within the European Union have given rise to a number of studies, trying to analyse and interpret why women (and men) choose not to have (many) children. One attempt in this direction is made by an ongoing EU-project, involving eight countries, including Sweden. Qualitative interviews focusing on couples' decisions to have- or not have - children have been carried out in each c

Diffractive photoproduction of psi(2S) mesons at HERA

Results on diffractive photoproduction of psi(2S) mesons are presented using data collected between 1996 and 2000 with the H1 detector at the HERA ep collider. The data correspond to an integrated luminosity of 77 pb(-1). The energy dependence of the diffractive psi(2S) cross section is found to be similar to or possibly somewhat steeper than that for J/psi mesons. The dependences of the elastic a
