Nanowires for Biosensing: Lightguiding of Fluorescence as a Function of Diameter and Wavelength

Semiconductor nanowires can act as nanoscaled optical fibers, enabling them to guide and concentrate light emitted by surface-bound fluorophores, potentially enhancing the sensitivity of optical biosensing. While parameters such as the nanowire geometry and the fluorophore wavelength can be expected to strongly influence this lightguiding effect, no detailed description of their effect on in-coupl

Educational lighting and learning performance

The education of our children is one of the most important assignments for society. The facilities where education is conducted have been seen as one important part of a good educational result. In order to create good facilities the lighting situation has for long been seen as one important factor both concerning daylight and electrical lighting. The chapter describes the development of research

Employment Protection Reform, Enforcement in Collective Agreements and Worker Flows

We analyze a reform of notice periods for employer-initiated separations in Sweden, which reduced the notice periods for newly hired older workers substantially but implied minor or no changes in the advance notices for younger workers. The reform was initiated at different times depending on collective agreement. These circumstances provide ample opportunity for the identification of its effects.

Job polarization, job tasks and the role of firms

Using detailed Swedish matched employer–employee data, I show evidence of within-firm job polarization. Applying a decomposition framework, I find that both within-firm and between-firm components are important for overall job polarization. Results also indicate that the degree of routineness is the most important explanation for the observed within-firm pattern. Bringing the analysis down to the

Optimisation and integration of membrane processes for the fruit juice industry

IntroductionMembrane processes can be either used in direct competition with conventional separation processes or in combination with these to cover a wider separation range. The focus of this work is on the applications in an apple juice plant using membrane processes in combination with conventional separation processes, i.e. separators and evaporators.Traditional Apple Juice Plant The tradition

Benchmarking energy efficiency transitions in MENA countries

Pursuing energy efficiency as a national policy objective is a cross-cutting challenge for governments. The outcomes expressed in proxies such as energy intensity of the economy and/or energy productivity are linked to so many variables and interventions operating at different levels; from macroeconomic conditions, technology development and path dependency, energy supply and pricing regimes to in

Cost-effectiveness of club-foot treatment in low-income and middle-income countries by the Ponseti method

BACKGROUND: Club foot is a common congenital deformity affecting 150 000-200 000 children every year. Untreated patients end up walking on the side or back of the affected foot, with severe social and economic consequences. Club foot is highly treatable by the Ponseti method, a non-invasive technique that has been described as highly suitable for use in resource-limited settings. To date, there ha

Cloning arbuscule-related genes from mycorrhizas

Until recently little was known about the identity of the genes expressed in the arbuscules of mycorrhizas, due in part to problems associated with cloning genes from the tissues of an obligate symbiont. However, the combination of advanced molecular techniques, innovative use of the materials available and fortuitous cloning has resulted in the recent identification of a number of arbuscule-relat

Telomere length, telomerase reverse transcriptase promoter mutations, and melanoma risk

Telomere repeats at chromosomal ends, critical for genomic integrity, undergo age-dependent attrition and telomere length has been associated with different disorders including cancers. In this study, based on 1469 patients and 1158 healthy controls, we show a statistically significant (P = 6 × 10-10 ) association between increased telomere length and melanoma risk. Mendelian randomization, using

Young consumers’ valuations of new payment services

Purpose: The purpose of this study is to gain a more in-depth understanding of the factors influencing how young consumers value mobile payment services and to develop a conceptual model that describes this process. Design/methodology/approach: Content analysis combined with interaction analysis was applied to empirical material consisting of nine focus group interviews with a total of 55 young ad

Aesthetic outcome following breast-conserving surgery assessed by three evaluation modalities in relation to health-related quality of life

Background: The aim of this study was to compare the agreement between three different methods for evaluation of aesthetic outcome following breast-conserving surgery and adjuvant radiotherapy: a patient questionnaire, panel evaluation of photographs and the software BCCT.core. A further aim was to examine how these modalities predict health-related quality of life as measured by the validated Bre

B cells treated with CTB-p210 acquire a regulatory phenotype in vitro and reduce atherosclerosis in apolipoprotein E deficient mice

Objective: Intranasal immunization with a fusion protein of the ApoB100-derived peptide p210 and the cholera toxin B subunit (CTB-p210) has previously been shown to induce mucosal tolerance and reduce atherosclerosis development, but the exact mode of action remains to be elucidated. Recent studies have indicated an important role for B cells in mucosal tolerance, in particular by induction of reg

Performance of a Semi-Closed Oxy-Fuel Combustion Combined Cycle (scoc-cc) with an Air Separation Unit (ASU)

The objective of this paper is to evaluate the performance of a semi-closed oxy-fuel combustion combined cycle (SCOC-CC) and its power penalties. The power penalties are associated with CO2 compression and high-pressure oxygen production in the air separation unit (ASU). The paper discusses three different methods for high pressure oxygen (O2) production. Method 1 is producing O2 directly at high

Cone beam CT for QA of synthetic CT in MRI only for prostate patients

Purpose: Magnetic resonance imaging (MRI)-only radiotherapy is performed without computed tomography (CT). A synthetic CT (sCT) is used for treatment planning. The aim of this study was to develop a clinically feasible quality assurance (QA) procedure for sCT using the kV-cone beam CT (CBCT), in an MRI-only workflow for prostate cancer patients. Material and method: Three criteria were addressed;

Glucagon-like peptide-1 receptor agonists for type 2 diabetes : A rational drug development

Today, glucagon-like peptide-1 (GLP-1) receptor agonists are established glucose-lowering drugs used in the management of type 2 diabetes. Their development emerged from the understanding that a combined islet dysfunction comprising of impaired insulin secretion and exaggerated glucagon secretion is the key defect of hyperglycemia. GLP-1 was shown to target these defects, and after the discovery t

Closing the loops in the pulp and paper industry with membrane technology

Membrane technology is a relative new technology in the pulp and paper industry with interesting applications in the water loop, the by-product loop and the chemical loop. The technology was pioneered in the pulp and paper industry by DDS Filtration, now Alfa Laval Nakskov in the 1970’ies and this article reviews the opportunities to use membrane technology in the different loops investigated over
