Öresund is one of the areas in the world with most ship movements. More than 40,000 ships pass through the sound in the direction north-south or the opposite every year. Other ships/ferries frequently cross the sound in the direction east-west or west-east. The ships carry goods and/or passengers in huge volumes. Since Öresund is a quite narrow sound with a difficult navigation situation, many ris

The paper presents a review of the scientific literature on computer modeling of socio-technical systems. The aim is to briefly review and discuss modeling approaches that are suitable for the simulation of socio-technical systems, specifically in the context of risk and vulnerability analysis of critical infrastructures. It is found that seven main socio-technical modeling approaches can be disce

The aim of the present study was to examine mean HbA1c and blood pressure levels during a 5 year period in 442 type 1 adult diabetic patients in relation to the incidence and progression of retinopathy, nephropathy and to cardiovascular morbidity and mortality. The study showed, that in patients under routine care at a diabetic unit with four visits to the out-patient clinic per year, the intraind

The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to

Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

Guide mot diskriminering, trakasserier och kränkande särbehandling FÖR MEDARBETARE PÅ EKONOMIHÖGSKOLAN VID LUNDS UNIVERSITET 3 Inledning Den här guiden riktar sig till dig som är anställd på Ekonomihögskolan vid Lunds universitet. Syftet med guiden är att informera om vad diskriminering, trakasserier och kränkande särbehandling innebär men också hur vi hanterar händelser som upplevs vara diskrimin

Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed isotope signatures and fractionations to biogeochemical processes occurring in the rice soil environment and we suggested that 2’deoxymugineic acid (DMA) could play an important role for rice

Objectives To examine whether multimorbidity aggregates in families in Sweden.Design National explorative family study.Setting Swedish Multigeneration Register linked to the National Patient Register, 1997-2015. Multimorbidity was assessed with a modified counting method of 45 chronic non-communicable diseases according to ICD-10 (international classification of diseases, 10th revision) diagnoses.

Introduction: The purpose of this study was to experimentally investigate the effects of changes in both quantity and quality of use of social networking sites (SNS) on measures of anxiety, depression, stress, self-esteem, loneliness, problematic social media use, and present focused awareness. Method: Participants were randomly assigned to three different conditions: reducing SNS time to 30 minut

Background: The optimal timing of oral anticoagulation for prevention of early ischaemic stroke recurrence in people with acute ischaemic stroke and atrial fibrillation remains uncertain. We aimed to estimate the effects of starting a direct oral anticoagulant (DOAC) early (≤4 days) versus later (≥5 days) after onset of ischaemic stroke. Methods: For this systematic review and meta-analysis we sea

Salinity gradient energy (SGE) can play an important role in the energy transition from fossil-based sources to renewable sources. Its potential is estimated to be around 625 TWh·a-1 corresponding to 3% of global electricity consumption [1]. SGE sources are most abundant in the estuaries where rivers meet seawater. However, it is also available in different forms such as brackish water, brine etc

Objective: To evaluate under- and overreporting and their determinants in the EPIC :24-hour diet recall (24-HDR) measurements collected in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Cross-sectional analysis. 24-HDR measurements were obtained by means of a standardised computerised interview program (EPIC-SOFT). The ratio of reported energy intake (EI) to estim

Background: Various factors modulate circulating testosterone in men, affecting interpretation of testosterone measurements. Purpose: To clarify factors associated with variations in sex hormone concentrations. Data Sources: Systematic literature searches (to July 2019). Study Selection: Prospective cohort studies of community-dwelling men with total testosterone measured using mass spectrometry.

Background: Hypertension is the leading risk factor for cerebral small vessel disease. We aimed to determine whether antihypertensive drug classes differentially affect microvascular function in people with small vessel disease. Methods: We did a multicentre, open-label, randomised crossover trial with blinded endpoint assessment at five specialist centres in Europe. We included participants aged

Background: Several aggregate data meta-analyses have provided estimates of the effectiveness of influenza vaccination in community-dwelling elderly people. However, these studies ignored the effects of patient-level confounders such as sex, age, and chronic diseases that could bias effectiveness estimates. We aimed to assess the confounder-adjusted effectiveness of influenza vaccines on laborator
