The lamellar mesophase formed by surfactant 1,4-bis(2-ethylhexyl) sodium sulfosuccinate (AOT) in deuterated water is mixed with poly(dimethylacrylamide) (PDMAA) polymers of low molecular weight ((M) over bar (n) = (2-20) x 10(3)). The mixtures separate into microphases (lamellar plus isotropic polymer solution). Their microstructures are studied by microscopy, small-angle X-ray scattering (SAXS),
Amphibians are declining worldwide, but lack of long-term regional data makes identifying possible causes difficult, hindering conservation efforts. We evaluated whether habitat destruction, terrestrial habitat adjacent to ponds and the physico-chemical characteristics of ponds could explain the regional and local decline of the spadefoot toad (Pelobates fuscus) in Sweden. Analyses of aerial photo
Introduction: Knowledge of longitudinal progression in mild Alzheimer’s disease (AD) is required for the evaluation of disease-modifying therapies. Our aim was to observe the effects of long-term cholinesterase inhibitor (ChEI) therapy in mild AD patients in a routine clinical setting. Methods: This was a prospective, open-label, non-randomised, multicentre study of ChEI treatment (donepezil, riva
In the present paper we deal with integrators relying on Finite Elements in time for general hyperelastic models which guarantee the conservation of the momentum maps as well as of the total energy within the calculation accuracy. In the isotropic case, eigenvalue-based constitutive laws are, on the one hand, very significant to model the behaviour of various materials. On the other hand, it will
Problem: Kan den externa värderingen, i form av aktiekursen, förklaras av en enskild aktivitet eller av flera aktiviteter i läkemedelsföretagens produktlivscykler? Syfte: Syftet med denna uppsats är att pröva om förändringar i läkemedelsföretagens börskursutvecklingar kan förklaras av aktiviteter i företagens produktlivscykler. Metod: För att på bästa sätt uppfylla vårt syfte är uppsatsen indelad
The purpose of this Master’s Thesis is to create a model of a converting line factory. The model will be used to investigate factory performance when altering the order structure as well as other what-if scenarios. The model should also be easily adaptable so that it can be used to model other factories as well without the need to rebuild it from scratch. The main results of this study show that
Blood low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and triglyceride levels are risk factors for cardiovascular disease. To dissect the polygenic basis of these traits, we conducted genome-wide association screens in 19,840 individuals and replication in up to 20,623 individuals. We identified 30 distinct loci associated with lipoprotein concentrations (each
There is a growing gap between tourism's rapidly growing greenhouse gas emissions and the sector's 'aspirational' emission reduction targets as well as the international policy consensus to reduce emissions from this and all other sectors of the economy. The transport component is the largest GHG contributor to the global tourism system. In the absence of supranational policy agreements to curb em
In this paper I explore how the US-American competitive cooking show MasterChef Junior assigns its 8 to 13- year-old contestants with a notion of strength. In the first part of the paper I will demonstrate how the show constructs different categories of knowledge and values of food and food practices which I will define as soft and hard culinary capital. I will describe how food is presented, how
While ecosystem service (ES) assessments become a more and more important source of knowledge, there is a need for synthesis approaches that make the results usable to support decisions. Effective synthesis approaches can reduce the information burden produced by multiple ES assessments and help decision-makers to compare alternative options and to assess their impacts. In this review, we focus on
Ambient temperature strongly determines the behaviour, physiology, and life history of all organisms. The technical assessment of organismal thermal niches in form of now so-called thermal performance curves (TPC) thus has a long tradition in biological research. Nevertheless, several traits do not display the idealized, intuitive dome-shaped TPC, and in practice assessments often do not cover the
Objectives: ACST-2 is currently the largest trial ever conducted to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in patients with severe asymptomatic carotid stenosis requiring revascularization. Methods: Patients are entered into ACST-2 when revascularization is felt to be clearly indicated, when CEA and CAS are both possible, but where there is substantial uncertainty
This work aims at studying photoionization dynamics from atoms and surfaces at attose time scales. The work was based on development and applications of a high repetition rate High-order Harmonic Generation (HHG) light source that utilizes Optical Parametric Amplification (OPA) laser technology. The laser system delivers few-cycle pulses in the near infrared (IR) at a repetition rate of 200 kHz.

Many industries, which are producing sludge in large quantities, depend on sludge dewatering technology to reduce the corresponding water content. A key design parameter for dewatering equipment is the capillary suction time (CST) test, which has, however, several scientific flaws, despite that the test is practical and easy-to-perform. The standard CST test has a few considerable drawbacks: its l
