Sailing towards a circular economy: conditions for increased reuse and remanufacturing in the Scandinavian maritime sector

The transition to a Circular Economy (CE) requires enabling conditions that remove existing barriers in product life extension and material recovery operations. This contribution investigates barriers to material resource efficiency strategies in the maritime sector in Scandinavia and discusses the potential of policy interventions to enable increased reuse and remanufacturing of ship components.

Measuring Institutions : What We Do Not Know

The last two decades have seen a significant increase in the number and quality of cross-national measures of institutions, which are also covering longer and longer time spans. However, despite the considerable progress that has been made, important measurement issues linger. This chapter argues that the key future challenge for the measurement of institutions is how to square objective or direct

"Vi klimatforskare stödjer Greta och skolungdomarna"

DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

Strong association between vibration perception thresholds at low frequencies (4 and 8 Hz), neuropathic symptoms and diabetic foot ulcers

Aims To investigate whether multi-frequency measurement of vibration perception thresholds (VPTs) can identify individuals with a high risk of developing diabetic foot ulcer or neuropathic symptoms. Methods VPTs were measured at six different frequencies (4, 8, 16, 32, 64 and 125 Hz) on metatarsal heads 1 and 5 on the sole of the foot using a standard VibroSense Meter device in 535 type 1 diabetic

Surgical fasciectomy versus collagenase injection in treating recurrent Dupuytren disease : Study protocol of a randomised controlled trial

Introduction: There is no definitive cure for Dupuytren disease (DD), and recurrence of finger contractures after treatment is common. Surgical fasciectomy is considered the standard treatment method for recurrence, although associated with a high incidence of complications. Collagenase injection, a non-surgical treatment option, has been shown to be a safe and effective method; however, most stud

Guarding the Guards: Accountable Authorities in VANETs

In this paper we present an approach to gaining increased anonymity from authorities within a VANET. Standardization organizations and researchers working on VANETs recognize privacy as highly important. However, most research focuses on privacy from other vehicles and external attackers, as opposed to privacy from system-administrating authorities. Our proposed solution forces authorities to reso

Fully coupled thermo-mechanical modelling of the initial phase of the Friction Stir Welding Process using Finite Element Analysis

In the present study a finite element model of the FSW process is built and a FSW butt weld of two aluminium alloy 2024-T3 plates is simulated using a fully coupled thermo-mechanical analysis. Besides the welded panels, the model includes the backing plate and the welding tool as physical bodies, which makes the simulations more realistic. The model also includes conductive heat transfer between t

The associations of daylight and melatonin receptor 1B gene rs10830963 variant with glycemic traits : the prospective PPP-Botnia study

Background: Seasonal variation in glucose metabolism might be driven by changes in daylight. Melatonin entrains circadian regulation and is directly associated with daylight. The relationship between melatonin receptor 1B gene variants with glycemic traits and type 2 diabetes is well established. We studied if daylight length was associated with glycemic traits and if it modified the relationship

Dislocation Generation from Grain Boundaries in Nanosized Cu-beams

As the dimensions of a structure are decreased towards the nanometer scale, the mechanical response to loading deviates from what is observed macroscopically. This is due to a change in material properties stemming from the relative increase in number of surface atoms as compared to bulk atoms. Surface atoms lack some of their neighboring atoms, leading to a reorganization of the electron clouds a

Biomass steam gasification in bubbling fluidized bed for higher-H 2 syngas : CFD simulation with coarse grain model

A comprehensive coarse grain model (CGM) is applied to simulation of biomass steam gasification in bubbling fluidized bed reactor. The CGM was evaluated by comparing the hydrodynamic behavior and heat transfer prediction with the results predicted using the discrete element method (DEM) and experimental data in a lab-scale fluidized bed furnace. CGM shows good performance and the computational ti

The Vel blood group system : a review

CONCLUSIONS: The blood group antigen Vel has been one of immunohematology's greatest enigmas: the variation in antigen strength from one individual to another, the property of anti-Vel to readily hemolyze Vel+ red blood cells (RBCs), and the difficulty to screen for sufficient numbers of Vel- blood donors had made Vel a tough nut to crack. In 2013, a small, previously unknown protein called small

The bar-hinge motor : A synthetic protein design exploiting conformational switching to achieve directional motility

One challenge to synthetic biology is to design functional machines from natural building blocks, from individual amino acids up to larger motifs such as the coiled coil. Here we investigate a novel bipedal motor concept, the Bar-Hinge Motor (BHM), a peptide-based motor capable of executing directed motion via externally controlled conformational switching between a straight bar and a V-shaped hin

University–industry collaboration : A literature review and synthesis

This study applies a systematic literature review and qualitative content analysis to identify and synthesize key factors that enable collaborative innovation between industry and universities. Using a keyword search in the Web of Science database, the review identified 40 papers that were frequently cited on the topic. Results were summarized into seven main themes or central factors stimulating
