Phase-transformations interacting with plasticity – a micro-sphere model applied to TRIP steel

We present an efficient model for the simulation of polycrystalline materials, particularly accounting for the interactions of solid to solid phase-transformations and plasticity. The underlying one-dimensional model is embedded into amicro-sphere formulation in order to simulate three-dimensional boundary value problems. Representative numerical examples are provided for both the micro-level and

A diet based on multiple functional concepts improves cardiometabolic risk parameters in healthy subjects

Background: Different foods can modulate cardiometabolic risk factors in persons already affected by metabolic alterations. The objective of this study was to assess, in healthy overweight individuals, the impact of a diet combining multiple functional concepts on risk markers associated with cardiometabolic diseases (CMD). Methods: Fourty-four healthy women and men (50-73 y.o, BMI 25-33, fasting

Mobile Manipulation with a Kinematically Redundant Manipulator for a Pick-and-Place Scenario

Mobile robots and robotic manipulators have traditionally been used separately performing different types of tasks. For example, industrial robots have typically been programmed to follow trajectories using position sensors. If combining the two types of robots and adding sensors new possibilities emerge. This enables new applications, but it also raises the question of how to combine the sensors

The dissemination of results from Supreme Audit Institutions: Independent partners with the media?

Maximising media coverage is one way for Supreme Audit Institutions (SAIs) to account for themselves and it has been argued that SAIs can become independent partners with the media. This strategy may appear appealing in particular when a response to audits is not compulsory. However, based on a case study of the Swedish National Audit Office (SNAO) in the years 2003-2007, this paper shows that sev

Meta-substituted Ru(II) rigid rods for sensitization of TiO(2)

Abstract in Undetermined Ruthenium polypyridyl rigid-rod compounds with phenylene-ethynelene (OPE) spacers and an isophthalic acid (Ipa) binding group were synthesized and characterized for sensitization of nanocrystalline TiO(2) (anatase) thin films. Density functional theory predicted that the most stable structure oriented the isophthalic group about 45 degrees from normal to the TiO(2) surface

Effects of enzyme feeding strategy on ethanol yield in fed-batch simultaneous saccharification and fermentation of spruce at high dry matter

Background: To make lignocellulosic fuel ethanol economically competitive with fossil fuels, it is necessary to reduce the production cost. One way to achieve this is by increasing the substrate concentration in the production process, and thus reduce the energy demand in the final distillation of the fermentation broth. However, increased substrate concentration in simultaneous saccharification a

Why Do You Vote and Vote as You Do?

P>The conventional rational voter model has problems explaining why people vote, since the costs typically exceed the expected benefits. This paper presents Swedish survey evidence regarding i) Why people vote, ii) Why people vote as they do and their beliefs about why others vote as they do, and iii) How bad not voting and voting selfishly are perceived to be. Large majorities find it important t

ATLAS search for a heavy gauge boson decaying to a charged lepton and a neutrino in pp collisions at root s=7 TeV

The ATLAS detector at the LHC is used to search for high-mass states, such as heavy charged gauge bosons (W'), decaying to a charged lepton (electron or muon) and a neutrino. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of 4.7 fb(-1). No excess beyond Standard Model expectations is observed. A W' with Seq

Soft Tissue Sarcoma Patterns multiplicity, heterogeneity and growth characteristics

Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. In study I, we demonstrated that 20% of the patients in a population-based series of 818 STS developed second primary malignancies. An increased risk of

Hydroxy-PCBs, PBDEs, and HBCDDs in serum from an elderly population of Swedish fishermen's wives and associations with bone density

Lack of human exposure data is frequently reported as a critical gap in risk assessments of environmental pollutants, especially regarding "new" pollutants. The objectives of this study were to assess serum levels of the persistent 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153), hydroxylated polychlorinated biphenyl metabolites (OH-PCBs), polybrominated diphenyl ethers (PBDEs), and hexabromocyclododec

Micromechanical Modelling of Wood and Fibre Properties

Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. In the present study both experimental and numerical work concerning the stiffness and the hygroexpansion properties of wood and of fibres and variations in them is presented. The experimental work involves both

Särskolebarn i integrerad skolbarnsomsorg

Popular Abstract in Swedish Huvudtanken i svensk välfärdspolitik är att genom generella åtgärder skapa ett samhälle tillgängligt för alla medborgare. Det är därför viktigt att undvika segregering och särlösningar och i stället höja normalverksamhetens standard. Fritidshemmets mål och uppgifter är desamma för alla barn och kvaliteten i verksamheten ska vara så hög att alla barns behov tillgodoses. The main idea behind the Swedish welfare state is to create a society accessible to all citizens by using to general measures. It is, therefore, important to avoid segregation and special solutions, and instead increase the standard of normal activities. The objectives and tasks of day centres for school-age children are the same for all children and the quality of the operations should be of a st

Structural characterization of amorphised InAs with synchrotron radiation

Extended X-ray absorption fine structure measurements have been utilized to determine the structural parameters of InAs amorphised by ion implantation. Relative to crystalline standards, increases in bond length and Debye-Walter factor were apparent. Our results indicate that a total coordination number of four atoms, as observed in the crystalline phase, is retained in the amorphous material. Fur

Method for analysis of methyltetrahydrophthalic acid in urine using gas chromatography and selected ion monitoring

A method for the determination of methyltetrahydrophthalic acid (MTHP acid), a metabolite of methyltetrahydrophthalic anhydride (MTHPA) in human urine, was developed. The investigated MTHP acid was obtained by hydrolysis of a commercial MTHPA mixture, composed of three major isomers. These were synthesized and identified as 3-methyl-delta 4-tetrahydrophthalic anhydride, 4-methyl-delta 4-tetrahydro

Regulated delivery of glial cell line-derived neurotrophic factor into rat striatum, using a tetracycline-dependent lentiviral vector.

In this study, a tetracycline-regulated lentiviral vector system, based on the tetracycline-dependent transactivator rtTA2S-M2, was developed for controlled expression of glial cell line-derived neurotrophic factor (GDNF) in the rat brain. Expression of the marker gene green fluorescent protein (GFP) and GDNF was tightly regulated in a dose-dependent manner in neural cell lines in vitro. Injection

Justification of Federation International de Beton, fib, 2000 model for elastic modulus of normal and high-performance concrete, HPC

This article outlines an experimental and theoretical comparison between the fib 2000 model for elastic modulus of normal concrete, NC, and HPC and 144 laboratory tests. Two dimensions of specimen were studied (diameters 56 and 100 mm) and one climate (20 degreesC, sealed or with ambient relative humidity, RE, 60%). The age dependence did not seem to be well correlated between the derived and the
