Habitat-choice interactions between pike predators and perch prey depend on water transparency

A mesocosm experiment indicated that water transparency influenced antipredator behaviour in young-of-the-year perch Perca fluviatilis, which partly contradicts another study by showing that high transparency decreases rather than increases perch antipredatory use of vegetated habitats when predators are also free to choose habitat. The present study emphasizes the importance of simultaneously con

Foster parents in Multidimensional Treatment Foster Care: How do they deal with implementing standardized treatment components?

This article focuses upon 28 Swedish foster parents and their experience of working in a manual-based treatment program - Multidimensional Treatment Foster Care (MTFC) - focusing on treating troubled youth. Using interviews and questionnaires, the study addresses how foster parents perceive the components and core terms specific to MTFC. Both quantitative and qualitative analyses were conducted. I

A multidimensional multispecies continuum model for heterogeneous biofilm development

We propose a multidimensional continuum model for heterogeneous growth of biofilm systems with multiple species and multiple substrates. The new model provides a deterministic framework for the study of the interactions between several species and their effects on biofilm heterogeneity. It consists of a system of partial differential equations derived on the basis of conservation laws and reaction

Scotopic colour vision in nocturnal hawkmoths

Humans are colour-blind at night, and it has been assumed that this is true of all animals. But colour vision is as useful for discriminating objects1 at night as it is during the day. Here we show, through behavioural experiments, that the nocturnal hawkmoth Deilephila elpenor uses colour vision to discriminate coloured stimuli at intensities corresponding to dim starlight (0.0001 cd m-2). It can

Changes in expression of PACAP in rat sensory neurons in response to sciatic nerve compression.

In the present study, expression of pituitary adenylate cyclase-activating polypeptide (PACAP) in rat dorsal root ganglion (DRG) neurons and sciatic nerve following experimental sciatic nerve compression was studied with the use of quantitative immunohistochemistry and in situ hybridization. Previously, we have investigated changes in PACAP expression after nerve transection and, here, the far mor

The experience of Middle Eastern men living in Sweden of maternal and child health care and fatherhood: focus-group discussions and content analysis.

Objective To describe how men from the Middle East experience Swedish maternity and child health care. An integral part of the aim of this study has also been to describe the experiences of men from the Middle East when becoming and being a father in Sweden. Design, setting and participants an exploratory, qualitative study using focus-group discussions and individual interviews, with a semi-st

Evaluation of nasal barrier dysfunction at acute- and late-phase reactions in a guinea pig model of allergic rhinitis

Allergic rhinitis is a common disease characterized by the symptoms of pruritus, sneezing, hypersecretion and nasal blockage. Increased mucosal barrier permeability has been suggested to be an indicator for the severity of allergic rhinitis. This study investigates the passage of radiolabelled albumin from the nasal mucosal circulation into the lumen in guinea pigs intraperitoneally sensitized and

Past occurrences of hypoxia in the Baltic Sea and the role of climate variability, environmental change and human impact

The hypoxic zone in the Baltic Sea has increased in area about four times since 1960 and widespread oxygen deficiency has severely reduced macro benthic communities below the halocline in the Baltic Proper and the Gulf of Finland, which in turn has affected food chain dynamics, fish habitats and fisheries in the entire Baltic Sea. The cause of increased hypoxia is believed to be enhanced eutrophic

Mapping of quick clay formations using geotechnical and geophysical methods

Quick clay has been involved in most serious, large clay slides in Sweden, Norway, and Canada. This paper describes geotechnical and geophysical methods that can be used to locate and map the extent of quick clay formations. Surface resistivity measurements and four different sounding methods have been tested. The results have been compared with sensitivities determined using fall-cone tests. The

Systemic lupus international collaborating clinics renal activity/response exercise - Development of a renal activity score and renal response index

Objective. To develop a measure of renal activity in systemic lupus erythematosus and use it to develop a renal response index. Methods. Abstracted data from the medical records of 215 patients with lupus nephritis were sent to 8 nephrologists and 29 rheumatologists for rating. Seven nephrologists and 22 rheumatologists completed the ratings. Each physician rated each patient visit with respect to

Peas and pancakes: On apparent disagreement and (null) light verbs in Swedish

Having shown how Construction NOM and Construction PROP differ, I demonstrate that the subject of Construction PROP is clausal. I argue that the topmost XP of the subject phrase of both constructions contains a null neuter element. This accounts for the neuter predicative agreement; hence the idea of default agreement or semantic agreement can be dismissed. I also argue that the subject in (ii) co

On the wings of physics

Some of Maurice Jacob's contributions to the European physics community are described, by giving examples of his great achievements. I have come to the conclusion that his success depended on his far-reaching vision, his ability to define the goals and to find realistic solutions for realizing them. He was a trustworthy partner in negotiations due to his outstanding breath of knowledge, his high s

Revisiting the politics of expertise in light of the Kyoto negotiations on land use change and forestry

This paper examines the close links between knowledge-making authority and decision making authority in the multilateral negotiations on terrestrial sinks of greenhouse gases. Drawing upon social constructivist science studies and public sphere theories in international relations, the paper traces the communicative contexts in which state actors have struggled to bring meaning to the sink concept

Breast cancer incidence in ex-smokers in relation to body mass index, weight gain and blood lipid levels

According to several studies breast cancer is more common among former smokers. This study explores whether this association has any relationship with anthropometric measurements or blood lipid levels. The 2082 ex-smokers (mean age 49.9 years) in the Malmo Preventive Cohort were followed for an average of 13.3 years using official cancer registries. This yielded 93 incident breast cancer cases. Oe

Red supergiants as potential Type IIn supernova progenitors: Spatially Resolved 4.6 Mum CO Emission Around VY CMa and Betelgeuse

We present high-resolution 4.6 mu m CO spectra of the circumstellar environments of two red supergiants (RSGs) that are potential supernova (SN) progenitors: Betelgeuse and VY Canis Majoris (VY CMa). Around Betelgeuse, (CO)-C-12 emission within +/-3 '' (+/-12 km s(-1)) follows a mildly clumpy but otherwise spherical shell, smaller than its similar to 55 '' shell in KI lambda 7699. In stark contras

Temperature-corrected spectroscopic evaluation method for gas concentration monitoring

Combustion exhaust monitoring was simulated by measurement on a sulfur dioxide flow at different temperatures using broadband absorption spectroscopy and electrochemical analysis. A linear relationship with varying rates of slope for different temperatures was found between the gas concentrations obtained using the two methods, attributed to the influence of gas volume increase and absorption line

Newborn human brain identifies repeated auditory feature conjunctions of low sequential probability

Natural environments are usually composed of multiple sources for sounds. The sounds might physically differ from one another only as feature conjunctions, and several of them might occur repeatedly in the short term. Nevertheless, the detection of rare sounds requires the identification of the repeated ones. Adults have some limited ability to effortlessly identify repeated sounds in such acousti
