A method for studying PCB desorption behaviour from sediments using supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) is presented. Four sediments were investigated and extracted with supercritical carbon dioxide employing increasingly harsher extraction conditions ranging from 40 degrees C and 12MPa to 100 degrees C and 36.5 MPa. To ensure quantitative extractions, the

2,5-Furandicarboxylic acid (FDCA) is a promising bio-based chemical that may serve as a green alternative to polyethylene terephthalate as a raw material in manufacturing plastics. A novel method to produce FDCA from the oxidation of 2-formyl-2-furancarboxylic acid (FFCA) using resting cells of Gluconobacter oxydans was tested in this project. The different subspecies of G. oxydans including DSM 2

Proximal femoral (hip) strength computed by subject-specific CT scan-based finite element (FE) models has been explored as an improved measure for identifying subjects at risk of hip fracture. However, to our knowledge, no published study has reported the effect of loading condition on the association between incident hip fracture and hip strength. In the present study, we performed a nested age-

Information on past land cover in terms of absolute areas of different landscape units (forest, open land, pasture land, cultivated land, etc.) at local to regional scales is needed to test hypotheses and answer questions related to climate change (e.g. feedbacks effects of land-cover change), archaeological research, and nature conservancy (e.g. management strategy). The palaeoecological techniqu

Inte bara potthål och andra korta gupp, utan även mycket långa ojämnheter på vägbanan skapar stora dynamiska laster då tunga fordon färdas där. Dessa laster skadar vägbanan och gör att slitaget ökar så att livslängden på vägbanan förkortas. Detta leder i sin tur till att kostnaden för att hålla vägbanan i acceptabelt skick ökar. Syftet med detta examensarbete är pröva en metod för att beräkna och

The new generation of mobile devices, such smartphones and tablets, make users no longer constrained to traditional devices, such as PCs and laptops, in order to access needed information. This has given rise to an innovation in Business Intelligence (BI) coined mobile BI, which is currently embraced by different organizations. Information systems (IS) innovations are in general accompanied by “bu

Volatile conflicts, poverty and suppression of basic human rights stemming from one's political or religious affiliations, gender and race, are some of the various reasons why thousands flee home in the hopes of finding some kind of security. As the world observes the appalling deterioration of conflicts in Western Sudan, Iraq and Haiti, we simultaneously observe neighbouring or developed coun

Ability to pay is recognized in most Member States as a constitutional parameter to design fair tax systems and foundations of such principle can be found also in EU primary law. However, our investigation, based on the analysis of the ECJ's case law concerning tax benefits related to personal and family circumstances, will demonstrate that ability to pay can't be considered a general prin

Our purpose is to study the relation and dynamic between offering services higher up in the value chain, risk, trust and cultural differences for an offshore outsourcing vendor. The research of our thesis is based on a qualitative case study with interviews, observations and document studies at our case company OKS Group. Our theoretical framework consists of models regarding outsourcing relations

Results are reported for biosensors based on two different preparations of the same enzyme, laccase from Cerrena unicolor, one lyophilized and one stored frozen at - 18degreesC, for monitoring phenolic compounds. The enzyme was adsorbed on graphite electrodes and these were used in a flow through wall jet cell connected to a flow injection set-up. The electrodes were used at - 50 mV vs. AgAgCl. Th

In 1998 Bergendahl & Son AB, as the sole owner alongside with BTL as a partner, created Matomera. Matomera was unique in Sweden in its concept of selling groceries only on the Internet with no supporting physical store. Instead they used a dedicated warehouse especially designed for this purpose. In B2C e-commerce the buying decisions and the face-to-face communication between consumers and co

BackgroundCurrent guidelines from Scandinavian Neuro Committee mandate a 24-hour observation for head trauma patients on anticoagulants, even with normal initial head CT scans, as a means not to miss delayed intracranial hemorrhages. This study aimed to assess the prevalence, and time to diagnosis, of clinically relevant delayed intracranial hemorrhage in head trauma patients treated with oral ant

Anaplastic large cell lymphomas (ALCLs) are rare CD30+ peripheral T-cell lymphomas (PTCLs) classified according to the expression of the anaplastic lymphoma kinase (ALK+) protein or not (ALK-). We have analysed the outcome and risk factors for survival in a population-based bi-national cohort of patients with systemic ALK+ ALCL. A total of 122 adult (≥18 years) patients diagnosed with ALK+ ALCL be

The Xga blood group is differentially expressed on erythrocytes from men and women. The underlying gene, PBDX, was identified in 1994, but the molecular background for Xga expression remains undefined. This gene, now designated XG, partly resides in pseudoautosomal region 1 and encodes a protein of unknown function from the X chromosome. By comparing calculated Xga allele frequencies in different

The neonatal period of very preterm infants is often characterized by a difficult adjustment to extrauterine life, with an inadequate nutrient supply and insufficient levels of growth factors, resulting in poor growth and a high morbidity rate. Long-term multisystem complications include cognitive, behavioral, and motor dysfunction as a result of brain damage as well as visual and hearing deficits

INTRODUCTION: Knee injury history and increased joint load, respectively, are major risk factors for the development of knee osteoarthritis (OA). Lower extremity muscle function, such as knee muscle strength, influence joint load and may be important for the onset of knee OA. However, the role of muscle function as a possible modifiable protective mechanism for the development of OA after anterior

A simultaneous measurement of the three components of the top-quark and top-antiquark polarisation vectors in t-channel single-top-quark production is presented. This analysis is based on data from proton–proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139 fb−1, collected with the ATLAS detector at the LHC. Selected events contain exactly one iso

BACKGROUND: Cryptogenic stroke is a heterogeneous condition, with a wide spectrum of possible underlying causes for which the optimal secondary prevention may differ substantially. Attempting a correct etiological diagnosis to reduce the stroke recurrence should be the fundamental goal of modern stroke management.METHODS: Prospective observational international multicenter study of cryptogenic str
