Shredder residues of end-of-life vehicles and white goods are a complex waste stream, which nowadays most often is disposed of at industrial landfills. This paper describes the most important findings concerning the complex composition of the landfill leachate and its on-site, year-round treatment under cold-climate conditions. A 3-year investigation has confirmed that concentrations of different
Mesenchymal stroma cells (MSCs) have a high potential for novel cell therapy approaches in clinical transplantation. Commonly used bone marrow-derived MSCs (BM-MSCs), however, have a restricted proliferative capacity and cultures are difficult to standardize. Recently developed human embryonic stem cell-derived mesenchymal stroma cells (hES-MSCs) might represent an alternative and unlimited source
Commercial private equity as an investment industry have quickly grown since its formation in the late 80’s, and now account for a significant part of the investments made both globally and in Sweden. In 2014 the Swedish commercial private equity companies had a combined turnover of 311 billion SEK, accounting for around 9 % of Sweden’s GNP. The sector has been studied extensively by the investmen
Due to changed global conditions, The Swedish Migration Agency will have to reorganize and decrease its locations, in accordance with its business plan for 2021. The decision was based on a combination of a reduced number of asylum seekers in Sweden and reduced governmental funding of the agency. The agency will completely cease to operate in the municipality of Borås. Therefore, this paper focuse
Syfte: Syftet med denna studie är att undersöka hur en multidivisionell organisationsstruktur påverkar ett företags dynamiska kapabiliteter och således dess förmåga att uppnå konkurrensfördelar på en dynamisk marknad. Metod: Studien är en kvalitativ fallstudie av Bonnier Books med avgränsas till tre dotterbolag, där insamlingen av empiri gjorts utifrån semistrukturerade intervjuer och analys av o
This paper attempts to extend the knowledge in entrepreneurial theory, through the expansion of traditional concepts for entrepreneurial processes, to identify a new phenomenon in new venture creation. In combination with previous research on entrepreneurial processes, creation theory, user entrepreneurs and community-driven innovation in the sport industry, the study will focus on a single in-dep
This essay aims to study how communication technology, in the form of digital platforms such as Facebook and Twitter, affects citizens' engagement in the autocratic state of Myanmar. The theoretical framework implemented are the theories of participatory politics, as well as Robert Dahl's principles of democracy. Through the methods of case study and process tracing, it was concluded that
Titel: Utvärdering och effektivisering av projekteringsprocesser i ett medelstort byggföretag Författare: Daniel Larsson, Anton Bodin Handledare: Stefan Olander, Universitetslektor, Avdelningen för Byggproduktion, Lunds Tekniska Högskola Examinator: Anne Landin, Professor, Avdelningen för Byggproduktion, Lunds Tekniska Högskola Syfte & problemställning: Syftet är att utreda det utvalda fal
Chemo-enzymatic epoxidation of oleic acid (OA) and its methyl ester has been performed using hydrogen peroxide and immobilized lipase from Candida antarctica (Novozym(R) 435). The purpose of the study was to characterize the reaction under solvent-free conditions. The reaction temperature had a significant impact on epoxidation of OA. At lower temperatures, the substrate conversion was hindered by
BACKGROUND: A previous study has shown that pentoxifylline in combination with vitamin E can reverse radiation-induced fibrosis. The aim of the present study is to investigate if the same drugs could prevent radiation-induced side-effects in women with breast cancer. PATIENTS AND METHODS: A randomised, placebo-controlled, double-blind, parallel group trial was performed. Women with breast cancer w
Human biomonitoring (HBM) frameworks assess human exposure to hazardous chemicals. In this review, we discuss and summarize sample preparation procedures and analytical methodology for six groups of chemicals of emerging concern (CECs), namely diisocyanates, benzotriazoles, benzothiazoles, 4-methylbenzylidene camphor, isothiazolinones, fragrances, and non-phthalate plasticizers, which are increasi
This study reveals specific ion effects on particle formation during peristaltic pumping of a monoclonal Antibody (Antibody A). For this purpose, three anions in the direct Hofmeister series were selected, ranging from the kosmotropic SO42- to the more neutral Cl- and the chaotropic SCN-. Protein particle formation during peristaltic pumping is described primarily as a surface-driven mechanism. Th
The sector of residential buildings and service organizations uses 36% of the total energy in Sweden. In June 2006, it was decided by the Swedish parliament that the energy use in residential buildings and premises should decrease by 20% per heated unit area before 2020. To reach this goal, more energy efficient buildings must be produced as well as energy efficient improvements must be performed
A previously proposed model for non-stationary signals is extended in this contribution. The model consists of mul- tiple time-translated locally stationary processes. The opti- mal Ambiguity kernel for the process in mean-square-error sense is computed analytically and is used to estimate the time-frequency distribution. The performance of the kernel is compared with other commonly used kernels.
The fecal microbiota of two healthy Swedish infants was monitored over time by terminal restriction fragment length polymorphism (T-RFLP) analysis of amplified 16S rRNA genes. Principal component analysis (PCA) of the T-RFLP profiles revealed that the fecal flora in both infants was quite stable during breast-feeding and a major change occurred after weaning. The two infants had different sets of
The Gaussian wave model has been successfully used in ocean engineering for more than half a century. It is well understood, and there exists both exact theory and efficient numerical algorithms for calculation of the distribution of safety related wave characteristics, such as crest height and steepness. Its drawback is its lack of realism: it produces waves which are stochastically symmetric, bo
The aim of this study was to compare the performance of the enzymes produced by Trichoderma reesei Rut C30 and the good extracellular beta-glucosidase-producing mutant Trichoderma atroviride TUB F-1663 to that of commercial preparations in the enzymatic hydrolysis and the simultaneous saccharification and fermentation (SSF) of steam-pretreated spruce (SPS). The concentrated TUB F-1663 enzyme was f
The parameters affecting the lipase activity and operational lifetime during chemo-enzymatic epoxidation of fatty acids were investigated. Immobilized Candida antarctica lipase B (Novozym (R) 435) was incubated in the presence of various reaction components (i.e. toluene, water, H2O2, oleic acid, perpalmitic acid, and epoxystearic acid, respectively) at temperatures between 20 and 60 degrees C fol
During δ-aminolevulinic acid (ALA) based Interstitial Photodynamic Therapy (IPDT) a high light fluence rate is present close to the source fibers. This might induce an unintentional tissue temperature increase of importance for the treatment outcome. In a previous study, we have observed, that the absorption in the tissue increases during the treatment. A system to measure the local tissue tempera
