We present an approach to underwater electrical resistivity tomography surveying under conditions with several water layers with different resistivity in the water above the electrode layout. The approach is verified against a synthetic model example and tested in full scale on data from a field survey. The field survey was carried out in central Stockholm as part of pre-investigations for a new m

Wild bees are declining in intensively farmed regions worldwide, threatening pollination services to flowering crops and wild plants. To halt bee declines, it is essential that conservation actions are based on a mechanistic understanding of how bee species utilize landscapes. We aimed at teasing apart how foraging resources in the landscape through the nesting season affected nesting and reproduc

We discuss recent and on-going experiments, where molecular frame photoelectron angular distributions (MFPADs) of high kinetic energy photoelectrons are measured in order to determine the time evolution of molecular structures in the course of a photochemical event. These experiments include, on the one hand, measurements where single XUV/X-ray photons, obtained from a free electron laser (FEL) or

Ionization mechanisms of C60 molecules irradiated by a short intense 800-nm laser pulse are studied. Angle-resolved photoelectron spectra show above-threshold ionization (ATI) patterns with a low peak contrast and a remarkably smooth angular distribution. The results are interpreted by combining two theoretical models. A time-dependent Schrödinger equation (TDSE) calculation based on the B-spline

To meet multiple environmental objectives, integrated programming is becoming increasingly important for the Global Environmental Facility, the financial mechanism of the Multilateral Environmental Agreements, including the UN Convention to Combat Desertification. However, integration is often not well defined. We therefore focus on identifying key aspects of integration and assessing their implem

The Systolic Blood Pressure Intervention Trial (SPRINT) suggested a favourable effect of lowering blood pressure to < 120/80 mmHg in high-risk hypertensive patients; however, new American guidelines in 2017 have not followed SPRINT but lowered its recommended treatment target to < 130/80 mmHg. We aimed to review the latest research from large randomised controlled trials and observat

Osteoarthritis is a harmful joint disease but prediction of disease progression is problematic. Currently, there is only one modeling framework which can be applied to predict the progression of knee osteoarthritis but it only considers degenerative changes in the collagen fibril network. Here, we have developed the framework further by considering all of the major tissue changes (proteoglycan con

In order to investigate the molecular mechanisms by which the oncogenic mutant KIT/D816V causes transformation of cells, we investigated proteins that selectively bind KIT/D816V, but not wild-type KIT, as potential mediators of transformation. By mass spectrometry several proteins were identified, among them a previously uncharacterized protein denoted XKR5 (XK-related protein 5), which is related

This study aims to shed new light on the petroglyphs found at the site of Aspeberget 12 at the World Heritage site of Tanum, Sweden, from a semiotic perspective. We demonstrate the semiotics of power inherent in the arrangement of the petroglyphs. We start by describing the site in an archaeological way, in order to give an overview of the empirical material used in this case study. Against the ba

Purpose: This study examines how voice quality and multitalker babble noise affect immediate passage comprehension and the efficiency of information encoding into long-term memory in children with normal hearing. Method: Eighteen children (mean age = 9 years) with normal hearing participated. Immediate passage comprehension performance and delayed performance (after 5 to 8 days) were assessed for

Hur kyrkan framträder i det lokala sammanhanget beror på vilka delar av omvärlden den kyrkliga aktören relaterar till. I artikeln presenteras en modell för att beskriva och analysera kyrkan som välfärdsaktör. Artikeln är framskriven i ett teologiskt aktionsforskningsprojekt med Mölndals pastorat, i ett samarbete mellan Svenska kyrkans forskningsenhet och Socialhögskolan i Lund.

Kapitlet undersöker med hjälp av material från intervjuer och frågelistor vilka sociala relationer, normer och värderingar som sätts på prov vid lån och utlån av saker. Vilka förutsättningar finns det att genom erfarenheter från det privata lånandet öka lusten att delta i en mer hållbar delningsekonomi?

A firm understanding of the coupling between the deformation on different scales within a material is key when formulating multi-scale constitutive models. In many polymers, the macroscopic deformation is, to a large extent, dictated by the underlying molecular structure and how this evolves during loading. To gain information ab out the behaviour of the molecular structure during deformation, non

Induction heating has the potential to be a very efficient heating method and by using litz wires instead of copper tubes the losses can be significantly reduced. The drawback with litz is the fact that it comprises insulation materials with low temperature resistance, typically in the range 150 – 200 °C. In order to solve this problem a solution is to create channels in the litz structure in whic

SpoVD and PBP4b are structurally very similar high-molecular-weight, class B penicillin-binding proteins produced early during sporulation in Bacillus subtilis. SpoVD is known to be essential for endospore cortex synthesis and thereby the production of heat-resistant spores. The role of PBP4b is still enigmatic. Both proteins are synthesized in the cytoplasm of the mother cell. PBP4b remains in th

Monika Edgren är docent i historia och professor i genusvetenskap vid Malmö universitet. I denna bok presenterar 16 av hennes vänner och kollegor kritiska essäer på teman som anknyter till hennes intressen. Det handlar, som alltid i Monikas forskning, om makt, i alla dess former: maktspel mellan historiens människor och samhällets institutioner och normer, men också den makt som forskaren har över
