Nonlocal ultrafast demagnetization dynamics of Co/Pt multilayers by optical field enhancement

The influence on ultrafast demagnetization dynamics of metallic nano-structured gratings deposited on thin films of magnetic Co/Pt multilayers is investigated by the time-resolved optical Kerr effect. Depending on the polarization of the pump pulse, a pronounced enhancement of the demagnetization amplitude is found. Calculation of the inhomogeneous optical field distribution due to plasmon interac

Maximum likelihood estimation of local stellar kinematics

Context. Kinematical data such as the mean velocities and velocity dispersions of stellar samples are useful tools to study galactic structure and evolution. However, observational data are often incomplete (e. g., lacking the radial component of the motion) and may have significant observational errors. For example, the majority of faint stars observed with Gaia will not have their radial velocit

Src-Like Adaptor Protein (SLAP) Binds to the Receptor Tyrosine Kinase Flt3 and Modulates Receptor Stability and Downstream Signaling.

Fms-like tyrosine kinase 3 (Flt3) is an important growth factor receptor in hematopoiesis. Gain-of-function mutations of the receptor contribute to the transformation of acute myeloid leukemia (AML). Src-like adaptor protein (SLAP) is an interaction partner of the E3 ubiquitin ligase Cbl that can regulate receptor tyrosine kinases-mediated signal transduction. In this study, we analyzed the role o

Formation of pebble-pile planetesimals

Asteroids and Kuiper belt objects are remnant planetesimals from the epoch of planet formation. The first stage of planet formation is the accumulation of dust and ice grains into mm-cm-sized pebbles. These pebbles can clump together through the streaming instability and form gravitationally bound pebble `clouds'. Pebbles inside such a cloud will undergo mutual collisions, dissipating energy into

Biological effects of 2-oxoglutarate with particular emphasis on the regulation of protein, mineral and lipid absorption/metabolism, muscle performance, kidney function, bone formation and cancerogenesis, all viewed from a healthy ageing perspective state of the art - review article

The fact that men and women are living longer than they have ever done before is something in which we can all rejoice. However, the process of ageing is associated with changes in skeletal, muscular, gastrointestinal, neural hormonal and metabolic processes that seriously affect an individual's performance and quality of life. Indeed, Such changes can be contributory to a loss of independence in

The addition of transglutaminase improves the physical quality of extruded fish feed

The possibility of improving the physical quality of extruded fish feed using transglutaminase (TGase) treatment at different stages of the production process was investigated. The addition of TGase to the raw material mix and processing under high and medium moisture conditions significantly increased (p > 0.05) the durability, hardness and elasticity of fish feed pellets. However, the water stab

Energy Services in Sweden - Customer Relations towards Increased Sustainability

Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill. In this thesis, three particular field

Maternal use of antihypertensive drugs in early pregnancy and delivery outcome, notably the presence of congenital heart defects in the infants

Purpose To investigate the association between maternal use of antihypertensives in early pregnancy and delivery outcome, notably infant congenital malformations. Methods A cohort study of 1,418 women who had used antihypertensive drugs in early pregnancy but had no diabetes diagnosis were identified from the Swedish Medical Birth Register. Results There was an excess risk for placental abruption,

Conclusive English 'then' and Swedish 'då'. A corpus-based contrastive study.

Conclusive English 'then' and Swedish 'då' are compared on the basis of a bi-directional translation corpus. The examples are classified into five different uses according to certain formal and contextual criteria. The two words are shown to have obvious functional similarities: in each of the categories distinguished 'then' and 'då' are the preferred translation equivalents of each other. But the

Coffee and tea intake and risk of brain tumors in the European Prospective Investigation into Cancer and Nutrition cohort study.

BACKGROUND: In a recent US cohort study, total coffee and tea consumption was inversely associated with risk of glioma, and experimental studies showed that caffeine can slow the invasive growth of glioblastoma. OBJECTIVE: The objective was to examine the relation between coffee and tea intake and the risk of glioma and meningioma in a large European cohort study, the European Prospective Investig

Preterm infants' early developmental status is associated with later developmental outcome

Aim: To assess the development of preterm infants from 40 weeks gestational age to 18 months corrected age in order to identify early predictors of later development. Methods: Fifty-one infants were involved. Infant development was assessed at 40 and 44 weeks gestational age with the Brazelton Neonatal Behavioral Assessment Scale and a Self-Regulation Scale and at 3, 6, 10, 18 months corrected age

Monte Carlo feature selection and rule-based models to predict Alzheimer's disease in mild cognitive impairment

The objective of the present study was to evaluate a Monte Carlo feature selection (MCFS) and rough set Rosetta pipeline for generating rule-based models as a tool for comprehensive risk estimates for future Alzheimer's disease (AD) in individual patients with mild cognitive impairment (MCI). Risk estimates were generated on the basis of age, gender, Mini-Mental State Examination scores, apolipopr

Perpetuating "New Public Management' at the expense of nurses' patient education: a discourse analysis

This study aimed to explore the conditions for nurses' daily patient education work by focusing on managers' way of speaking about the patient education provided by nurses in hospital care. An explorative, qualitative design with a social constructionist perspective was used. Data were collected from three focus group interviews and analysed by means of critical discourse analysis. Discursive prac

Transcutaneous carbon dioxide monitoring for the prevention of neonatal morbidity and mortality.

Carbon dioxide (CO2) measurement is a fundamental evaluation in a neonatal intensive care unit (NICU), as both low and high values of CO2 might have detrimental effects on neonatal morbidity and mortality. Though measurement of CO2 in the arterial blood gas is the most accurate way to assess the amount of CO2, it requires blood sampling and it does not provide a continuous monitoring of CO2.

Dynamic early Holocene vegetation development on the Faroe Islands inferred from high-resolution plant macrofossil and pollen data

Vegetation dynamics during the earliest part of the Holocene (11,250-10,250 cal yr BP) have been reconstructed from a lacustrine sequence on Sandoy, the Faroe Islands, using detailed plant macrofossil and pollen evidence. The plant macrofossils suggest the initial vegetation was sparse herb and shrub tundra, with Salix herbacea and open-ground species, followed by the development of a denser and m
