BACKGROUND: Alcohol screening scores 5 on the Alcohol Use Disorders Identification Test–Consumption (AUDIT-C) up to a year before surgery have been associated with postoperative complications, but the association with postoperative health care use is unknown. This study evaluated whether AUDIT-C scores in the year before surgery were associated with postoperative hospital length of stay, total ICU
This thesis investigates the connection between open access – the free online availability and distribution of scientific and scholarly publications – and the ‘developing world’ from a post- development perspective. It takes a discourse analytical approach, drawing predominantly on Michel Foucault’s understanding of discourse. It aims to answer the following questions: - Which notions of science,
To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. Our experiments on seed germinat
In terrestrial ecosystems, a large portion (20-80%) of the dissolved Si (DSi) in soil solution has passed through vegetation. While the importance of this terrestrial Si filter is generally accepted, few data exist on the pools and fluxes of Si in forest vegetation and the rate of release of Si from decomposing plant tissues. We quantified the pools and fluxes of Si through vegetation and coarse w
Environmental loads from the building and its services must be minimised. The study aims to determine material quantities, manufacturing energy and how material choice affect manufacturing energy. An inventory of materials in domestic water, waste water, space heating and ventilation services are made and manufacturing energy are calculated based on LCA’s. Finally energy need for alternative mater
Background: Accurate assessment of myocardium at risk (MaR) after acute myocardial infarction (AMI) is necessary when assessing myocardial salvage. Contrast-enhanced steady-state free precession (CE-SSFP) is a recently developed cardiovascular magnetic resonance (CMR) method for assessment of MaR up to 1 week after AMI. Our aim was to validate CE-SSFP for determination of MaR in an experimental po
The most common malignant brain tumor in adults is a glioma called glioblastoma multiforme (GBM). About 300 persons are diagnosed with GBM every year in Sweden. Unfortunately, it is also the most aggressive brain tumor and as of today, it is not possible to cure it. Despite treating the patients with surgery, radiation and chemotherapy, the median survival is only 15 months. The main problem with
Abstract Background: Despite the large availability of 3T MR scanners and the potential of high field imaging, this technical platform has yet to prove its usefulness in the cardiac MR setting, where 1.5T remains the established standard. Global perfusion of the left ventricle, as well as the coronary flow reserve (CFR), can provide relevant diagnostic information, and MR measurements of these par
Volvo Construction Equipment are investigating new machine concept that involve fast charging with high power. This should be done automatically and independent on humans. The thesis set out to develop and design a complete system solution for this, including the connector and the automated system for connection. The thesis is based on previous projects presented at LTH in various mechatronics cou
The essay, The New Clothes of Death is about the funeral customs in Sweden from a culture-historical perspective with an ethnological touch. The essay deals with our present day relation to death and how this can be transformed to the dead person. The questions are highlighted with observations from two funerals, one cremation and, studies of the cemetery environment and the culture of the graves.
Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. Large surveys are up and coming, and several surveys are already working, and with these, the aim is high quality abundance measurements of several ele
Animals are impacted by the humidity of their surrounding environment, it affects their ability of thermoregulation, water retention and their overall well-being. For small insects the effects of the surrounding humidity is even more important as they have a limited water storage which depletes faster in a drier environment. Some insects such as the vinegar fly Drosophila melanogaster have develop
This thesis explores the audience’s reactions in regards to the phenomenon of norm-breaking ads in Sweden, focusing on the representation of immigrant minorities in advertisements. The aim is to understand if, how, and why, these ads engage audiences online and offline, at a time where public interest in institutionalized politics is on the decrease. The interviews and photo elicitation are a way
How can a small fire at a subcontractor in the USA lead to a multimillion dollar loss at a Swedish telephone company, and how can a single machine breakdown lead to a complete production stop at a production company? With today logistics and production trends, where terms such as Lean Production, Six Sigma, 5S, and World Class Manufacturing are used every day, production companies are introducing
Power supply is a social necessity, and will so continue to be in the near future. Therefore, safe and steady deliverance of power supply is a fundamental duty of the societies and the preparedness of the vulnerability of the infrastructures is highly prioritized. The power supply comprises every component needed for transmission of electrical power from generation to consumption, power transform
Abstract Moraxella catarrhalis is a new pathogenic, gram negative bacterium that is the cause of many respiratory tract infections. MID was found to be a unique protein with Ig binding capacities. Moraxella catarrhalis immunoglobulin D (IgD)-binding protein (MID) is an outer membrane protein that has specific binding affinity to the soluble cell bound human IgD. A short fragment of MID comprised
Ever since corporate social responsibility (CSR) became a prominent school of thought, this subject has constantly upgraded itself to keep pace with the fast-changing world. However, given that CSR is largely a market-driven, top-down response, it has entered into a bottleneck where downstream stakeholders are out of the picture. Speaking of improving labour standards via CSR, when business and no
Title: Development of a Forecasting Model for Original Equipment Manufacturer (OEM) Components. A Design Science Study at Tetra Pak. Authors: Faruk Kodzaga & Giacomo Daniele Supervisor: Jan Olhager, Department of Industrial Management and Logistics Background: The importance of accurate demand forecast is set due to the drivers of short lead-times, just-in-time-deliveries and cost effective
Speech and gestures express meaning together, connecting lexical and visuo-spatial representations in the speaker’s mind. Several studies have demonstrated uptake of spatial information from gestures however usually following explicit instructions to recreate or recall spatial features, deviating from typical listening situations. It remains unclear whether exposure
