Computational homogenisation of thermo-viscoplastic composites : Large strain formulation and weak micro-periodicity

In this article, a first order two-scale finite element framework for fully coupled thermo-mechanical problems at finite deformations is considered. The scale bridging is achieved under application of Hill–Mandel condition based boundary conditions at the lower scale. Emphasis of the present article is on the extension of the concept of weak micro-periodicity to thermo-mechanically coupled problem

Invisible and Ignored : The Archaeology of Nineteenth-Century Subalterns in Sweden

This paper aims to discuss subalterns in different social environments in Sweden. The potential of archaeological studies of landless subalterns in rural and urban areas are shown though a number of case studies. It is argued that archaeology can show the multivocality of the lives of the subalterns, in the same way as it shows how the subalterns organized their daily life. This is done through th

Fluids, Gels and Crystals : Phase behavior of binary thermoresponsive microgel mixtures

Particles that are a hundred- to ten thousand times smaller than the width of a hair are commonly referred to as colloidal particles. Colloidal particles occur in a variety of products, like foodstuffs (marmelade and dairy products), construction materials (cement) and stained glass. In water, these particles are strongly affected by the Brownian force: an force that was discovered in 1827 by the Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction. Mixing two microgels that collapse at different

Identification of linear, multivariable systems operating under linear feedback control

The possibility of estimating process parameters using input-output data collected when the system operates in closed loop is discussed in this paper. Concepts that are useful for a systematic treatment of the problem are introduced. The results refer to the case where the regulator is a linear feedback law or alternates between several such laws. It is shown that a straightforwardly applied ident

Five-year changes in dietary intake and body composition in adolescents with severe obesity undergoing laparoscopic Roux-en-Y gastric bypass surgery

Background: Information is scarce on long-term changes in energy intake (EI), dietary energy density (DED), and body composition in adolescents undergoing laparoscopic Roux-en-Y gastric bypass (RYGB). Objectives: To investigate long-term changes in EI, DED, and body composition in adolescents after LRYGB. Setting: University hospitals, multicenter study, Sweden. Methods: Eighty-five adolescents (6

Effects of the coronary artery disease associated LPA and 9p21 loci on risk of aortic valve stenosis

Background: Aortic valve stenosis (AVS) and coronary artery disease (CAD) have a significant genetic contribution and commonly co-exist. To compare and contrast genetic determinants of the two diseases, we investigated associations of the LPA and 9p21 loci, i.e. the two strongest CAD risk loci, with risk of AVS. Methods: We genotyped the CAD-associated variants at the LPA (rs10455872) and 9p21 loc

Physical activity may compensate for prolonged TV time regarding pulse rate—a cross-sectional study

Background. Regular exercise reduces pulse rate, but it is less clear how prolonged sitting time affects pulse rate. Our hypothesis was that high physical activity could compensate for prolonged sitting time regarding the pulse rate. Methods. Regression analysis was performed on cross-sectional data including 47,457 men and women based on two Swedish cohort studies, EpiHealth (18–45 years) and Lif

Modified balanced truncation preserving ellipsoidal cone-invariance

We consider model order reduction of stable linear systems which leave ellipsoidal cones invariant. We show how balanced truncation can be modified to preserve cone- invariance. Additionally, this implies a method to perform external positivity preserving model reduction for a large class of systems.

Estimating CDKN2A mutation carrier probability among global familial melanoma cases using GenoMELPREDICT

BACKGROUND: Although rare in the general population, highly penetrant germline mutations in CDKN2A are responsible for 5-40% of melanoma cases reported in melanoma-prone families. We sought to determine whether MELPREDICT was generalizable to a global series of melanoma families and whether performance improvements can be achieved.METHODS: 2,116 familial melanoma cases were ascertained by the inte

Extruded Unripe Plantain Flour as an Indigestible Carbohydrate-Rich Ingredient

There is a growing interest in the development of functional ingredients, including those with high indigestible carbohydrate content. Unripe plantain flour (UPF) is a source of indigestible carbohydrates, type II resistant starch (RS) in particular. A major drawback of UPF, however, is that its RS content decreases sharply after wet heat treatment. Here, we explore the possibility of preparing an

Human–Robot Interaction Based on Motion and Force Control

Industrial robots typically require detailed programming and carefully configured work cells to perform well. The large engineering effort implicates high cost and long preparation time, and this is the major obstruction when mediating tasks to robots. The research in this thesis therefore aims to make robot programming faster and more accessible. Methods that allow for programmers to mediate and

From Fauna to Flames : Remote Sensing with Scheimpflug Lidar

This thesis presents applications of the Scheimpflug Lidar (S-Lidar) method. The technique has been applied to combustion diagnostics on a scale of several meters as well as fauna detection and monitoring over distances of kilometers. Lidar or laser radar is a remote sensing technique where backscattering of laser light is detected with range resolution along the direction of the laser beam. It is

Rapid confocal imaging of vesicle-to-sponge phase droplet transition in dilute dispersions of the C 10 E 3 surfactant

The lamellar-to-sponge phase transition of fluorescently labelled large unilamellar vesicles (LUVs) of the non-ionic surfactant triethylene glycol mono n-decyl ether (C 10 E 3 ) was investigated in situ by confocal laser scanning microscopy (CLSM). Stable dispersions of micrometer-sized C 10 E 3 LUVs were prepared at 20 °C and quickly heated at different temperatures close to the lamellar-to-

Complex Interventions and Interorganisational Relationships: Examining Core Implementation Components of Assertive Community Treatment

Introduction: There is increasing interest in implementing evidence-based integrated models of care in community-based mental health service systems. Assertive Community Treatment (ACT) is seen as an attractive, and at the same time challenging, model to implement in sectored service settings. This study investigates the implementation process of such an initiative.Methods: Interviews were conduct
