Abnormal eating behaviors are overrepresented in the autism spectrum disorders, including food refusal, pica, rumination, and selective eating. Those disturbances can have detrimental complications and are often resistant to treatment. In autism spectrum disorders the background factors to eating disturbances are more complex than in the general child population, and sensory abnormalities, rituali

Injection into the MAX IV Storage Rings will not make use of a conventional local injection bump with dipole kickers. Instead, pulsed multipole injection will be applied. Previously, it was foreseen to use a pulsed sextupole magnet similar to what KEK had originally designed for the PF ring. But after seeing encouraging results with a prototype nonlinear kicker magnet developed for BESSY-II, pulse

The performance of a turbo code is dependent on two properties of the code: its distance spectrum and its suitability to be iteratively decoded. Both these properties are dependent on the specific interleaver used in the turbo-coding scheme. This paper describes a strategy for interleaver design that includes a criterion for the performance of iterative decoding. This criterion is based upon corre

An improved understanding of the response of forest ecosystems to elevated levels of CO2 in the atmosphere is crucial because atmospheric CO2 concentration continues to increase at an accelerating rate and forests are an important sink in the global carbon cycle. Several CO2-enrichment experiments have now been running for more than 10 years, with highly variable short-term results after the first

When evaluating whether the effect of one treatment is larger than that of another the first step in the comparison is to decide what should be understood by the statement that one patient has achieved a greater effect than has another patient. When the outcome variable is quantitative, measured on a ratio scale, absolute or relative effects are the most commonly used effect measures; however, suc

I antologin In Tension between Organization and Profession diskuterar en rad svenska och skandinaviska forskare olika vardagsproblem som individer i offentlig verksamhet upplever. Varför tycks sjukfrånvaro och utbrändhet ständigt öka samtidigt som resurserna inom offentlig sektor blir allt mindre? Är det förresten en bild som stämmer? I denna antologi sätts individen i centrum; det är individens r

A quite common view is that the scientific persona matters less in contemporary Western knowledge societies. Large research groups produce new scientific discoveries gathered around impersonal expert system. However, it is also well known that scientific cultures differ widely. In physics, the projects are quite impersonal, sometimes including thousands of persons. The prime example is the CERN or

This study presents the concentrations of about 50 metals and ions in 33 different brands of bottled waters on the Swedish market. Ten of the brands showed calcium (Ca) concentrations <= 10 mg L-1 and magnesium (Mg) levels < 3 mg L-1, implying very soft waters. Three of these waters had in addition low concentrations of sodium (Na; < 7 mg L-1), potassium (K; < 3 mg L-1) and bicarbonate (HCO3; <= 3

This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta

We present the magnetotransport properties of very thin (5-15 nm) single (Ga,Mn)As layers grown by low-temperature molecular beam epitaxy. A lower (Ga,Mn)As thickness limit of 5 nm for the ferromagnetic phase and the dependence of the Curie temperature on (Ga,Mn)As thickness are determined from electrical-transport measurements. The Curie temperature is determined to be 97 K for the thinnest ferro

Using the fixed point method we prove an existence result for positive solutions of nonlinear second order ordinary differential equations. An application to semilinear Schrodinger equations in exterior domains is also presented.

To use conventional ray tracing methods in Monte Carlo simulation of the collimator in a scintillation camera system can be time consuming. It is however necessary to take collimator interactions into account when simulating radionuclides emitting high-energy photons that can penetrate the septa in the collimator. In this work a statistical collimator algorithm, based on the Delta-Scattering metho

In the light of oil security concerns, the threat of climate change, and a desire to leverage competitive advantage for Sweden and its industries, the Swedish Government has announced a new policy target – the creation of the conditions necessary to break Sweden’s dependence on oil and fossil fuels by 2020. Notably, the Swedish Government stresses national opportunities and highlights two aspects

BACKGROUND AND AIMS: Helicobacter pylori is the major causative agent in peptic ulcer disease and is strongly implicated in the development of gastric cancer. It has also been linked, less strongly, to cardiovascular disease. The mechanisms by which certain Strains of H pylon induce platelet aggregation through interactions with platelet glycoprotein 1b have been previously described. METHODS: In

Many of the core proteins in Photosystem II (PS II) undergo reversible phosphorylation. It is known that protein phosphorylation controls the repair cycle of Photosystem II. However, it is not known how protein phosphorylation affects the partial electron transport reactions in PS II. Here we have applied variable fluorescence measurements and EPR spectroscopy to probe the status of the quinone ac

Adsorption of formic acid (HCOOH) on ZnO() surfaces has been investigated by means of quantum-chemical ab initio periodic Hartree–Fock calculations. One ‘bridging' structure, characterized by a formate anion symmetrically bonded via its two oxygens to two surface Zn atoms and the acidic proton bound to a surface oxygen, and two ‘unidentate' structures, characterized by one Znsurf–Oads bond and the
