Analysing neutron scattering data using McStas virtual experiments

With the intention of developing a new data analysis method using virtual experiments we have built a detailed virtual model of the cold triple-axis spectrometer RITA-II at PSI, Switzerland, using the McStas neutron ray-tracing package. The parameters characterising the virtual instrument were carefully tuned against real experiments. In the present paper we show that virtual experiments reproduce

Growth of Straight InAs-on-GaAs Nanowire Heterostructures.

One of the main motivations for the great interest in semiconductor nanowires is the possibility of easily growing advanced heterostructures that might be difficult or even impossible to achieve in thin films. For III-V semiconductor nanowires, axial heterostructures with an interchange of the group III element typically grow straight in only one interface direction. In the case of InAs-GaAs heter

The genetic background of gestational diabetes mellitus

The aims of this work is to better determine the genetic background of gestational diabetes (GDM) and to examine how specific genes affect the development of diabetes post partum. In the DiPiS (Diabetes Prediction in Skåne) study we typed for HLA-DQB1 alleled, the transcription factor 7-like 2(TCF7L2) rs7903146, rs12255372 and rs7901695 SNPs, the 1858 C>T SNP of the protein tyrosine phosphatase n

Combined search for the Standard Model Higgs boson using up to 4.9 fb(-1) of pp collision data at root s=7 TeV with the ATLAS detector at the LHC

A combined search for the Standard Model Higgs boson with the ATLAS experiment at the LHC using datasets corresponding to integrated luminosities from 1.04 fb(-1) to 4.9 fb(-1) of pp collisions collected at root s = 7 TeV is presented. The Higgs boson mass ranges 112.9-115.5 GeV, 131-238 GeV and 251-466 GeV are excluded at the 95% confidence level (CL), while the range 124-519 GeV is expected to b

Management intensity and vegetation complexity affect web-building spiders and their prey

Agricultural management and vegetation complexity affect arthropod diversity and may alter trophic interactions between predators and their prey. Web-building spiders are abundant generalist predators and important natural enemies of pests. We analyzed how management intensity (tillage, cutting of the vegetation, grazing by cattle, and synthetic and organic inputs) and vegetation complexity (plant

A simple many-body Hamiltonian for polymer-colloid mixtures: simulations and mean-field theory

We investigate depletion interactions between inert hard colloids in the presence of ideal polymers, with a focus on the case where the polymer radius of gyration (R-g) is equal to the radius of the colloids (R-c). We first establish structure and fluid-fluid phase equilibria of this model system as accurately as possible. To achieve this, we replace the ideal polymers by "effective spheres'', usi

Functional and structural characterization of domain truncated violaxanthin de-epoxidase

Photosynthetic organisms need protection against excessive light. By using non-photochemical quenching, where the excess light is converted into heat, the organism can survive at higher light intensities. This process is partly initiated by the formation of zeaxanthin, which is achieved by the de-epoxidation of violaxanthin and antheraxanthin to zeaxanthin. This reaction is catalyzed by violaxanth

Planning for Solar Buildings in Urban Environments

Popular Abstract in Swedish Solenergi kommer att vara en av de viktigaste miljövänliga energikällorna i framtiden, vilket innebär ökat antal solpaneler (för el och värme) som integreras i våra hus men också som fristående produktionsanläggningar. När man planerar framtida hus och stadsdelar är det viktigt att skapa de bästa förutsättningarna för solenergi eftersom hus och stadsdelar finns kvar i fEnergy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables. Solar energy is generally very suitable for producing this on-site renewable energy. Although solar

Techno-economic evaluation of stillage treatment with anaerobic digestion in a softwood-to-ethanol process.

ABSTRACT: BACKGROUND: Replacing the energy-intensive evaporation of stillage by anaerobic digestion is one way of decreasing the energy demand of the lignocellulosic biomass to the ethanol process. The biogas can be upgraded and sold as transportation fuel, injected directly into the gas grid or be incinerated on-site for combined heat and power generation. A techno-economic evaluation of the spru

Epidemiological studies of sociodemographic factors, early life factors, health, and medical care consumption among small children

By international standards, children in Sweden experience good health. Sweden has low infant mortality rates, low accident mortality rates, a high number of breastfed children and a high proportion of vaccinated children. However, during the past twenty years the prevalence of overweight children has doubled in Sweden, while that of obese children has increased 4-5 times. Furthermore, there has be

A Method for Including Moisture Safety in the Building Process

Many buildings, both new and old, suffer from moisture-related problems, with negative consequences on health, costs for rebuilding and lost confidence in the building industry. These problems could have been avoided if moisture issues had been focused on and dealt with throughout the building process. A method for including moisture safety in the building process has therefore been developed. The

Delay and secrecy: does industry sponsorship jeopardize disclosure of academic research?

The viability of modern open science norms and practices depend on public disclosure of new knowledge, methods, and materials. Aggregate data from the OECD show a broad shift in the institutional financing structure that supports academic research from public to private sponsorship. This article examines the relationship between industry sponsorship and restrictions on disclosure using individual-

Role of pituitary adenylate cyclase-activating polypeptide in the pancreatic endocrine system.

In the pancreatic islets, pituitary adenylate cyclase-activating polypeptide (PACAP) is expressed in beta cells and autonomic nerve terminals; the majority of these nerve terminals are parasympathetic. PACAP binds to three types of G protein-coupled receptors (GPCRs): VPAC1 receptors, VPAC2 receptors, and PAC1 receptors. All these receptor types are expressed in pancreatic islets. PACAP stimulates

Effect of steam cooking on the residual enzymatic activity of potatoes cv. Agria

BACKGROUND: The aim of this work was to study the influence of steam cooking on pectin methylesterase (PME) and endogenous alpha- and beta-amylase activities in different tissues (cortex and pith) of raw and heat-treated potatoes cv. Agria. Three different cooking temperatures were chosen (55, 70 and 85 degrees C). For each cooking trial, time-temperature profiles were recorded and the degree of c

Action Reconsidered. Cognitive Aspects of the Relation between Script and Scenic Action

Contemporary cognitive science challenges the idea about the human brain as a kind of computor. Instead the importance of the body for our way to understand and interact with the world has come into focus. Theories about the ”situated” and ”embodied” character of human cognition have entailed that notions like action, consciousness, and intersubjectivity have gained renewed scientific interest. On
