Pyrolysis modeling of PVC and PMMA using a distributed reactivity model

The thermal decomposition kinetics of poly(vinyl chloride) (PVC) and poly(methyl methacrylate) (PMMA) was studied by thermogravimetry using non isothermal experiments. A detailed kinetic analysis was done using the isoconversional methods (model-free) (including Friedman, Kissinger-Akhaira-Sunose (KAS) and Kissinger methods) and distributed reactivity model (model-fitting). The overall aim was to

Developing environmentally sustainable logistics. Exploring themes and challenges from a logistics service providers' perspective

The purpose of this paper is to explore themes and challenges in developing environmentally sustainable logistical activities. The approach is explorative with a cross sectional design that takes advantage of ten case studies out of selected logistics service providers (LSPs) operating primarily in the Scandinavian countries. The findings illustrate the major themes by analyzing current and future

Contrasting outcomes of family connections with varying therapeutic intensity in two Swedish treatment centres

Background: A proportion of individuals with pervasive emotion dysregulation or BPD have other severe co-principal diagnoses. In these cases is not uncommon for functioning to be reduced to the extent that living independently is not possible. These individuals can be referred nationally to a residential DBT treatment centre in South Sweden. Because family members of individuals referred nationall

Individual Placement and Support is the keyhole : Employer experiences of supporting persons with mental illness

BACKGROUND: Rehabilitation professionals are increasingly interested in the vocational rehabilitation approach called Individual Placement and Support (IPS) for persons with serious mental illness. OBJECTIVE: Since employers play a crucial supporting role for the IPS service user in the workplace, the aim of this study was to explore the experiences and views of employers in Sweden who have partic

Robust Multi-objective Optimization of Rare Earth Element Chromatography

Rare earth elements comprise the metallic elements known as lanthanides as well as scandium and yttrium. They are extensively used in modern technological industries and are considered as strategic commodities in many countries. Rare earth element minerals with varying compositions are found at deposits throughout the world, though most of the global REE supply comes from only a few sources.

Preparation of Al2O3/AlF3-Supported Ruthenium Catalysts for the Hydrogenolysis of Biodiesel-Derived Crude Glycerol

Hydrogenolysis of biodiesel-derived glycerol to value-added chemicals has emerged as an innovative approach to biowaste valorization for a more sustainable society. In the present work, Ru catalysts on Al2O3/AlF3 supports with different AlF3 content were prepared by the aqueous incipient wetness method and tested in the reaction of glycerol hydrogenolysis for the first time. The prepared catalysts

Managerialist studies in management accounting : 1990-2014

This article provides a review of managerialist studies in management accounting, as presented in ten leading accounting journals over the past 25 years. The review covers both interventionist and non-interventionist studies in which at least one of the aims is to directly support or help organizational decision-making and control. Non-interventionist research reviewed is descriptive or conceptual

Effective and robust energy retrofitting measures for future climatic conditions - Reduced heating demand of Swedish households

This article quantifies the energy saving potential and robustness of nine energy retrofitting measures, as well as four combinations of these, for residential building stocks of three major cities in Sweden and for five scenarios of future climatic conditions, downscaled by a regional climate model (RCM). The retrofitting measures are evaluated for five temporal resolutions of hourly, daily, mont

Learning and Teaching Sustainable Development in Global - Local Contexts

The overall aim of this thesis is to develop knowledge of teaching and learning sustainable development in global–local contexts. The research field is global learning for sustainable development (GLSD). Phenomenographic approach and contextual analysis were used as methods of analysis, and data was collected by Semi-structured interviews at secondary and upper secondary schools in Sweden.In Study

Mixed Block Copolymer Solutions: Self-Assembly and Interactions

Popular Science SummaryPolymers are giant molecules consisting of a repetition of many small units (monomers) that are linked together by chemical bonds. If we consider a long necklace as a polymer chain, the beads are the monomers and the part of the thread which connects the beads together is the chemical bond. Polymers are important materials in our everyday life and they can be found e.g., in This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (

Swedenborg and the Plurality of Worlds : Astrotheology in the Eighteenth Century

The possible existence of extraterrestrial life led in the eighteenth century to a heated debate on the unique status of the human being and of Christianity. One of those who discussed the new scientific worldview and its implications for theology was the Swedish natural philosopher and theologian Emanuel Swedenborg. This article discusses Swedenborg's astrotheological transformation, his use of t

Amyloid beta aggregation kinetics : The role of intrinsic and extrinsic factors.

As our knowledge of diseases and the development of new technologies increases,many health problems that were lethal in the past can now be cured. Couple thisto better life quality and improved medical care, we are seeing an increase in theaverage life expectancy. The downside to this, however, is that diseases that developwith age are becoming more common. There is currently an estimated 47 milliCerebral senile plaque is one of the main pathologies of Alzheimer's disease (AD). The amyloid cascade hypothesis suggests that the aggregation of amyloid beta (Abeta) peptide is involved in the pathogenesis of AD, which is supported by the fact that Abeta overexpression or production of more aggregation-prone variants lead to early-onset dementia. In this work, we mainly studied the in vitro Abet

Presence and persistence of australia antigen in patients with liver disorders

Patients with suspected disease involving the liver and seen at a department for infectious diseases were examined routinely for Au-antigen. Of 344 patients examined, 259 were found to have biochemical evidence of liver affection. Acute hepatitis was diagnosed in 129, including 65 with serum hepatitis, 18 with infections hepatitis and 46 with sporadic hepatitis. 62 patients had Au-antigen and 60 o

The potential for disruptive selection on growth rates across genetically influenced alternative reproductive tactics

A trade-off between survival to sexual maturity and mating success is common across alternative reproductive tactics (ARTs), and can lead to tactical disruptive selection on shared traits (i.e. positive selection gradient in one tactic, and negative selection gradient in another). We were interested in examining the theoretical possibility of tactical disruptive selection on intrinsic growth rate.

Variation Interpretation Predictors : Principles, Types, Performance, and Choice

Next-generation sequencing methods have revolutionized the speed of generating variation information. Sequence data have a plethora of applications and will increasingly be used for disease diagnosis. Interpretation of the identified variants is usually not possible with experimental methods. This has caused a bottleneck that many computational methods aim at addressing. Fast and efficient methods
