LRN 2016 SPECIAL – high capacity vehicles and modal shift from rail to road : combining macro and micro analyses

This paper addresses a road transport policy of allowing high capacity vehicles (HCVs) on the roads. The purpose is to examine the effect reduced road transport costs from HCVs can have on a modal shift. Two studies of HCV implementation in Sweden were combined. A micro-based case study modelled the distribution network of a major retailer in scenarios based on actual cost and flow data. A macro a

A Stabilizing Switching Scheme for Multi Controller Systems

The stability of a multi-controller system is analyzed using Lyapunov theory. Stability is guaranteed by a switching strategy determined by a combination of separate Lyapunov functions for the different controllers. The behavior on sliding surfaces is analyzed using non-smooth analysis according to Filippov. Two examples illustrate the theory.

Effect of alteplase on the CT hyperdense artery sign and outcome after ischemic stroke

OBJECTIVE: To investigate whether the location and extent of the CT hyperdense artery sign (HAS) at presentation affects response to IV alteplase in the randomized controlled Third International Stroke Trial (IST-3).METHODS: All prerandomization and follow-up (24-48 hours) CT brain scans in IST-3 were assessed for HAS presence, location, and extent by masked raters. We assessed whether HAS grew, p

Evaluation of δ13C in Carbonaceous Aerosol Source Apportionment at a Rural Measurement Site

The stable isotope of carbon, 13C, has been used in several studies for source characterization of carbonaceous aerosol since there are specific signatures for different sources. In rural areas, the influence of different sources is complex and the application of δ13C for source characterization of the total carbonaceous aerosol (TC) can therefore be difficult, especially the separation between bi

Centralization at Asine during the Bronze Age from a zooarchaeological perspective

From at least the Late Neolithic through the end of the Bronze Age and onwards, people continued to inhabit the settlement of Asine. For this reason, the site makes an interesting starting point for discussing long term change. This short paper presents new data on the animal bones from Bronze Age Asine. The data set is used for a zooarchaeological discussion of the site from a diachronic perspectFrom at least the Late Neolithic through the end of the Bronze Age and onwards, people continued to inhabit the settlement of Asine.

Go with the flow : visually mediated flight control in bumblebees

För ungefär 350 miljoner år sedan utvecklade de första insekterna förmågan att flyga och har sedan dess dominerat våra terrestra miljöer. Trots sina pyttesmå hjärnor och avsaknad av avancerade kontrollinstrument så lyckas flygande insekter på många vis utkonkurrera modern flygteknik. Humlor och bin kan till exempel leta upp en födokälla långt ifrån sitt bo, återvända hem igen och sedan upprepa denDespite their small brains and tiny eyes, flying insects are capable of detecting and avoiding collisions with moving obstacles, and with remarkable precision they navigate through environments of different complexity. For this thesis, I have investigated how bumblebees use the pattern of apparent image motion that is generated in their eyes as they move through the world (known as optic flow), in

Bridging the floods - The role of social learning for resilience building in urban water services

The development of cities is increasingly threatened by a worldwide water crisis. Urban water services (including drinking water, sanitation and drainage) are facing complex and multiple pressures, which are becoming increasingly frequent and severe. These pressures include floods, and the depletion, pollution and degradation of water resources and their associated ecosystems. These diverse pressu

IL-18 associated with lung lymphoid aggregates drives IFNγ production in severe COPD

Background: Increased interferon gamma (IFNγ) release occurs in Chronic Obstructive Pulmonary Disease (COPD) lungs. IFNγ supports optimal viral clearance, but if dysregulated could increase lung tissue destruction. Methods: The present study investigates which mediators most closely correlate with IFNγ in sputum in stable and exacerbating disease, and seeks to shed light on the spatial requirement

The coexistence of psychiatric and gastrointestinal problems in children with restrictive eating in a nationwide Swedish twin study

Background: Restrictive eating problems are rare in children but overrepresented in those with neurodevelopmental problems. Comorbidities decrease wellbeing in affected individuals but research in the area is relatively scarce. This study describes phenotypes, regarding psychiatric and gastrointestinal comorbidities, in children with restrictive eating problems. Methods: A parental telephone inter

Occupational therapy student experiences of a university mental health course based on an integrated application of problem-based and team-based learning

Background: The goal of problem-based and team-based learning (PBL/TBL) is to maximize student engagement and encourage interactive learning. Combining these methods in course design is described as a win-win situation that optimizes student learning, professional development, and uses varied teaching approaches that fit well within health science. More research is needed in the effectiveness of s

The BRCA1 c. 5096G>A p.Arg1699Gln (R1699Q) intermediate risk variant : Breast and ovarian cancer risk estimation and recommendations for clinical management from the ENIGMA consortium

Background We previously showed that the BRCA1 variant c.5096G>A p.Arg1699Gln (R1699Q) was associated with an intermediate risk of breast cancer (BC) and ovarian cancer (OC). This study aimed to assess these cancer risks for R1699Q carriers in a larger cohort, including follow-up of previously studied families, to further define cancer risks and to propose adjusted clinical management of female BR

Coffee drinking and mortality in 10 European countries : A multinational cohort study

Background: The relationship between coffee consumption and mortality in diverse European populations with variable coffee preparation methods is unclear. Objective: To examine whether coffee consumption is associated with all-cause and cause-specific mortality. Design: Prospective cohort study. Setting: 10 European countries. Participants: 521 330 persons enrolled in EPIC (European Prospective In

Female white-collar workers remain at higher risk of breast cancer after adjustments for individual risk factors related to reproduction and lifestyle

Objectives The aim was to investigate the variation in risk of breast cancer between occupational groups with a focus on white-collar and blue-collar workers and to investigate to what extent the differences were explained by risk factors related to reproduction and lifestyle. Methods Between 1991 and 1996, 14 119 women born between 1923 and 1950 and residents of Malmö, Sweden, were included in th

Good outcome scores and high satisfaction rate after primary total ankle replacement : 167 patients followed for 24 months in the Swedish Ankle Registry

Background and purpose — Total ankle replacement (TAR) is gaining popularity for treatment of end-stage ankle arthritis. Large patient-centered outcome studies are, however, few. Here, we report data from the Swedish Ankle Registry. Patients and methods — We examined outcomes after primary TAR in patients from the Swedish Ankle Registry using PROMs (Patient Reported Outcome Measures; generic: EQ-5

Trends that have influenced the Swedish radiography profession over the last four decades

Introduction: The expansion of the radiography profession in recent decades has widened the scope of radiographic practice. This has raised questions about which trends have had an impact on the profession over the years. The study aim was to explore trends that have influenced the radiography profession over the last four decades. Methods: A qualitative design was used. Eleven focus group intervi

Assessing ecosystem services and multifunctionality for vineyard systems

Vineyards shape important economic, cultural, and ecological systems in many temperate biomes. Like other agricultural systems, they can be multifunctional landscapes that not only produce grapes, but also for example serve as wildlife habitat, sequester carbon, and are places of rich traditions. However, research and management practices often focus mostly on individual, specific ecosystem servic

Editorial Styling : Between Creative Solutions and Economic Restrictions

While scholars have explored some areas of cultural production in fashion—including photography and modelling—styling has not received substantial attention. As a result, we know very little of the history of styling and its actual practice. This article examines how the stylist emerged as a new profession within fashion magazines in the 1960s and was established as profession in its own right by
