A boundary integral equation formulation for the Helmholtz equation in a locally perturbed half-plane

In this paper we study the application of boundary integral equation methods to the solution of the Helmholtz equation in a locally perturbed half-plane with Robin or impedance boundary conditions. This problem models outdoor noise propagation from a cutting onto a surrounding flat plane, and also the harbour resonance problem in coastal engineering. We employ Green's theorem to derive a system of

Fastighetsägare som prosumenter – stödstrukturer och hinder

Solceller har en viktig roll att fylla för att uppnå politiskt fattade mål om 100%hållbart elsystem. Det är rimligt att anta att det är i bebyggelsen som en storutbyggnad kommer att behöva ske eftersom det är existerande strukturermed nätanslutningar där det också finns möjlighet att använda den solel somproduceras. Fastighetsägare blir därmed en viktig aktörsgrupp att engagera.En relativt outfors

Stratigraphy of the Gorstian and Ludfordian (upper Silurian) Hemse Group reefs on Gotland, Sweden

The Hemse Group is one of the least understood stratigraphic units of the Silurian sequence of Gotland, Sweden. New results from airborne transient electromagnetic (ATEM) measurements in combination with previously published data from field studies and geophysical investigations shed new light on carbonate platform development during the early- to mid-Ludlow Hemse Group. ATEM reveals a transgressi

Influence of system operation on the design and performance of a direct ground-coupled cooling system

Sizing of borehole heat exchangers (BHEs) for direct ground cooling systems (DGCSs) is a critical part of the overall system design. This study investigates the thermal performance and sizing of a DGCS with two different operation strategies using experimental and simulation approaches. The traditional on/off operation strategy keeps a constant room temperature. The continuous operation strategy h

Natural Resources and Divergence : A Comparison of Andean and Nordic Trajectories

Is the 'natural resource curse' destiny? Are different ways to link natural resources and economic development? Using two particular regions as case studies, this edited collection examines the divergent development paths of natural resource rich countries over the past two centuries. Bolivia, Chile and Peru are neighbour states with a common history and are globally known by their mining endowmen

Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability

The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. This thesis presents the development of different

The impact of medication reviews conducted in primary care on hospital admissions and mortality : An observational follow-up of a randomized controlled trial

Background: Drug-related problems among the elderly population are common and increasing. Multi-professional medication reviews (MR) have arisen as a method to optimize drug therapy for frail elderly patients. Research has not yet been able to show conclusive evidence of the effect of MRs on mortality or hospital admissions. Aim: The aim of this study was to assess the impact of MRs’ on hospital a

Plant foods, dietary fibre and risk of ischaemic heart disease in the European prospective investigation into cancer and nutrition (EPIC) cohort

BACKGROUND: Epidemiological evidence indicates that diets rich in plant foods are associated with a lower risk of ischaemic heart disease (IHD), but there is sparse information on fruit and vegetable subtypes and sources of dietary fibre. This study examined the associations of major plant foods, their subtypes and dietary fibre with risk of IHD in the European Prospective Investigation into Cance

The Holmesian logician : Sherlock Holmes’ “Science of Deduction and Analysis” and the logic of discovery

This paper examines whether Sherlock Holmes’ “Science of Deduction and Analysis,” as reconstructed by Hintikka and Hintikka (in: Eco U, Sebeok TA (eds) The sign of three: Peirce, Dupin, Holmes, Indiana University Press, Bloomington, 1983), exemplifies a logic of discovery. While the Hintikkas claimed it does, their approach remained largely programmatic, and ultimately unsuccessful. Their reconstr

Effects of dipeptidyl peptidase 4 inhibition on inflammation in atherosclerosis : A 18F-fluorodeoxyglucose study of a mouse model of atherosclerosis and type 2 diabetes

Background and aims: Dipeptidyl peptidase 4 (DPP-4) inhibitors have anti-inflammatory and atheroprotective effects. We evaluated the effects of the DPP-4 inhibitor linagliptin on atherosclerotic plaque and hepatic inflammation using histology and 2-deoxy-2-[18F]-fluoro-D-glucose (18F-FDG), a positron emission tomography tracer of inflammation, in a mouse model of hypercholesterolemia and type 2 di

Blood polyphenol concentrations and differentiated thyroid carcinoma in women from the European Prospective Investigation into Cancer and Nutrition (EPIC) study

Background: Polyphenols are natural compounds with anticarcinogenic properties in cellular and animal models, but epidemiological evidence determining the associations of these compounds with thyroid cancer (TC) is lacking. Objectives: The aim of this study was to evaluate the relations between blood concentrations of 36 polyphenols and TC risk in EPIC (the European Prospective Investigation into
