När grundläggningen för en byggnad ska dimensioneras är snittkrafter och sättningar som kommer att uppstå i konstruktionen av stor betydelse. Det finns därför ett behov av att kunna beräkna dessa krafter och sättningar på ett säkert och relativt enkelt sätt.All buildings need a foundation that supports the structure. Since a layer of soil is most often in between a structure and the bedrock, a soil-structure interaction between the foundation and the soil beneath occurs. This interaction is of great importance when it comes to predicting the sectional forces that will arise in a structure, along with the settlement that occurs. Therefore the need to

The determination of a state’s right of self-defence is a complex process. In order for the use of force to be justifiable as an act of self-defence several criteria have to be fulfilled. According to Article 51 of the Charter of the United Nations a right of self-defence only exists when an armed attack has occurred. This is interesting because it had for a long time been argued, by states and in

Virtual Reality and advanced, interactive simulators illustrate the potentials of modern technology for improving the ecological validity of learning experiments. Yet much more preliminary work is needed to appreciate how these growingly complex means can be utilized to promote high-order emotional and motivational constructs of the user, such as self-efficacy. Drawing from the frameworks of serio

Populärvetenskaplig sammanfattning: Examensarbetet har gått ut på att med hjälp av satellitbilder göra markanvändningsdata för att förbättra en modell som beräknar vart de luftburna föroreningarna tar vägen. Föroreningarna svavel och kväve deponeras med olika hastighet över olika marktyper, därför vill man använda sig av markanvändningsdata i modellerna. Svavelutsläppen har ökat dramatiskt under Sulphur emissions during the last century has led to major acidification of the environment. The acidity of soil and water is a threat to health and economic interests of man, e.g. the food and paper/wood production in the agricultural and silvicultural industries. The Black Triangle region suffers from severe damage caused by acidification and actions to decrease the acid rain over fields and for

Kvinnor har låtit utföra abort under alla tider. Under merparten av historiens gång har ingreppet emellertid behandlats som ett samhälleligt tabu och var därför olagligt i flertalet länder fram till mitten på 1900-talet. Den sexuella revolutionen under 1960- och 1970-talet, i kombination med stora vetenskapliga framsteg på området för mänsklig reproduktion, har kommit att spela en avgörande roll fWomen have performed abortions during all times. For most of history abortion, however, has been treated as a social taboo and was therefore illegal in most countries until the mid 1900’s. The sexual revolution during the 1960’s and 1970’s, combined with major scientific advances in the field of human reproduction, has come to play a critical role in a changed view of the role of women in society.

BackgroundRisky sexual behavior is a public health challenge that significantly affects young people’s health and well-being in Sweden and throughout the world. Moreover, poor mental health, anxiety and depression among adolescents and young adults have increased in recent years. However, although hypothesized, the associations between general mental health and risky sexual behavior among young ad

Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate-human-land-cover interactions. We present the first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over the Holocene (last 11g€¯700g€¯calg€¯yrg€¯BP). We describe how vegetation cover has been quantified from pollen records at a 11 spatia

Background To benefit from the increasing clinical evidence, organisational changes have been among the main drivers behind the reduction of ICU mortality during the last decade. Increasing demand, costs and complexity, amplifies the need for optimisation of clinical processes and resource utilisation. Thus, multidisciplinary teamwork and critical care processes needs to be adapted to profit from

Summary: Background: Diabetes mellitus (DM) is a risk factor for peripheral arterial disease (PAD). Indications for open surgery in infrainguinal intermittent claudication (IC) are limited, and reports are lacking regarding outcomes in DM patients. Study aims were to compare short and long-term effects on major adverse cardiovascular events (MACE), acute myocardial infarction (AMI), stroke, major

IMPORTANCE: There is a lack of agreement on what constitutes successful outcomes for the process of health care transition (HCT) among adolescent and young adults with special health care needs.OBJECTIVE: To present HCT outcomes identified by a Delphi process with an interdisciplinary group of participants.DESIGN, SETTING, AND PARTICIPANTS: A Delphi method involving 3 stages was deployed to refine

Background: Osteoporosis is an underdiagnosed and undertreated disease worldwide. Recent studies have highlighted the use of simple vertebral trabecular attenuation values for opportunistic osteoporosis screening. Meanwhile, machine learning has been used to accurately segment large parts of the human skeleton. Purpose: To evaluate a fully automated deep learning-based method for lumbar vertebral

An experimental investigation has been performed where the influence of metal salts on soot formation has been studied. By combining two-dimensional laser-induced incandescence (LII) and elastic light scattering (ELS), two-dimensional information could be obtained on soot properties in the flames. For these studies, seven metal salts (NaCl, MgCl2, AlCl3, KCl, CaCl2, FeCl3 and ZnCl2) were dissolved

BACKGROUND: The aim of this study was to investigate possible associations between educational level, occupation, and hospitalization for inflammatory bowel disease.METHODS: A nationwide database was constructed by linking the Swedish Census to the Hospital Discharge Register in order to obtain data on all first hospitalizations for Crohn's disease (CD) and ulcerative colitis (UC) in Sweden during

A drop of systemic blood pressure (BP) occurring shortly after individuals move from supine or seated position to upright posture with subsequent prompt spontaneous resolution is a common physiological occurrence in humans. If the induced hypotension is severe, lightheadedness or postural instability leading to falls and injury may occur. By consensus, a transient systolic BP drop >40 mmHg within

Background: The European Colonoscopy Quality Investigation (ECQI) Group aims to raise awareness for improvement in colonoscopy standards across Europe. We analysed data collected on a sample of procedures conducted across Europe to evaluate the achievement of the polyp detection rate (PDR) target. We also investigated factors associated with PDR, in the hope of establishing areas that could lead t

Atomic layer etching (ALE) is a cyclic technique based on self-limiting processes, such as reactive gas adsorption and material removal by low-energy ion bombardment 1,2. In a typical ALE process Ar+ ions with energies of 20-60 eV are used to desorb the reaction products, e.g. SiClx for the Si ALE. Compared to a corresponding continuous reactive ion etching (RIE), where the ion energies often exce

The Gaia-ESO Survey is a public spectroscopic survey that targeted ≲105 stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering its final public release in May 2022. Unlike other spectroscopic surveys, Gaia-ESO is the only survey that observed stars across all spectral types with dedicated, specialised analyses: from O (Teff ∼ 30 000-52 000 K) all the way to K

Land cover governs the biogeophysical and biogeochemical feedbacks between the land surface and atmosphere. Holocene vegetation-atmosphere interactions are of particular interest, both to understand the climate effects of intensifying human land use and as a possible explanation for the Holocene temperature conundrum, a widely studied mismatch between simulated and reconstructed temperatures. Prog

This bachelor thesis deals with the reporting around the demonstration in Gothenburg on September 30th 2017 arranged by Nordiska Motståndsrörelsen (NMR), a Nordic Neo-Nazi movement. After a cultural debate in Sweden regarding freedom of speech and the attendance of the internet based right-winged alternative media Fria Tider on Mässan Bok & Bibliotek, also known as Bokmässan, always arranged a
