AIM: Self-expanding metallic stents (SEMS) as bridge to surgery have been questioned due to the fear of perforation and tumour spread. This study aimed to compare SEMS and stoma as bridge to surgery in acute malignant large bowel obstruction in the Swedish population. METHOD: Medical records of patients identified via the Swedish Colorectal Cancer Register 2007-2009 were collected and scrutinized.
There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). Therefore, the V2V system b
Today's security cameras typically capture either color images based on visible light or grayscale images based on both visible and near-infrared (NIR) light. This means that the performance is limited in situations where it is unclear which kind of image to capture. At dusk, for example, the visible light may not be sufficient to capture good-quality color images. On the other hand, capturing
The world is urbanising at an unprecedented rate. Cities are perceived to be potential solutions as well as causes of the many problems our society faces. On the one hand, cities are considered the driving forces of prosperity through innovation, wealth creation and growth. On the other hand, cities are perceived to be the roots of urgent environmental and social issues. In fact, the very notion o
Durable and robust product development is crucial for fulfilling customer expectations and ensuring satisfaction. In this context, thorough testing plays an essential role in identifying and addressing potential defects before products reach the final customer. IKEA, with its worldwide presence, aims to enhance its understanding of humidity's impact on kitchen fronts, one of the main product a
This report aims to develop a prototype for an intuitive microwave oven adapted for people with a cognitive illness. Cognitive disorders manifest themselves as a deterioration of mental abilities such as memory and planning. It is a category of disease that is becoming more widespread. A major problem among people suffering from a cognitive disorder is malnutrition. The disease might affect the ap
BACKGROUND: Distress tolerance (DT), anxiety sensitivity (AS), and intolerance of uncertainty (IU) are transdiagnostic vulnerability factors for emotional distress. Some have argued that AS and IU are components of DT but this hypothesis has not been properly addressed yet, and neither has their relationship to trait anxiety. Self-report studies and to lesser extent small clinical trials suggest t
There are probably thousands of old landfills in Sweden. Many of those contain recyclable materials, which could be excavated and recycled, but also might state environmental threats due to the large amount of non-recyclable and potentially hazardous waste buried. The present study is a study on two landfills in the municipality of Lund in southern Sweden, comprising of an industrial waste landfil
Stacked heterostructures of two-dimensional (2D) materials are emerging as promising building blocks for a wide range of applications. These devices, which range from tunneling transistors to light-emitting diodes, use the properties of 2D materials that are not accessible by their bulk counterparts. However, with the current growth techniques, a scalable mass production of high-quality 2D heteros
The tawny pipit (Anthus campestris) is a migrant bird adapted to dry, sandy habitats. In southern Sweden, land use changes have resulted in a reduction of suitable areas, affecting the birds’ population size. The SandLife Project was created with the goal to restore those sandy grasslands and improve local conditions to stimulate the recovery of biodiversity. In order to compare the current and th
Denna studie undersöker om införandet av Pay-for-Performance-program (P4P) i Sveriges primärvård har påverkat antal undvikbara slutenvårdstillfällen. I Västernorrland och Västerbotten har man använt sig av P4P med kvalitetsindikatorn undvikbar slutenvård under åren 2012-2014. Dessa län definieras som behandlingsgrupp i studien, och resterande län definieras som kontrollgrupp. Studien genomförs medThis study examines if the implementation of Pay-for-Performance-programmes (P4P) in Swedish primary care has had an effect on avoidable hospitalizations. In the counties Västernorrland and Västerbotten P4P has been used with the quality indicator avoidable hospitalization included in the programme during 2012-2014. These counties are defined as the treatment group in the study, and the remaining
During the Gorkha Earthquake in 2015 and its aftershocks, many schools have been damaged or collapsed in Nepal. Reconstruction of schools is still in progress. The lack of funding, resources, engineering skills, knowledge and accessibility makes it difficult for a lot of schools to reopen. My aim with this thesis project is to contribute to the resiliency of Nepal by proposing a design for a speci
At the turn of the twentieth century, Swedish painter Eugène Jansson created a series of paintings inspired by the city nights of Stockholm. This bachelor thesis examines the paintings in relation to urban gay spaces and sexual meetings in the early nineteen hundreds. The paintings by Jansson, himself a homosexual male, have at a few times vaguely been described as portraying the moments before an
Purpose: This study aims to add and extend onto the existing studies regarding open innovation in SMEs but to tackle it from a neglected angle that is operating during times of uncertainty. Additionally, this study seeks to explore the mechanisms which SMEs use to reduce R&D budgets, increase the quality of innovations and continue the pace of innovations during the COVID-19 pandemic. Methodo
The utilization of groundwater for the use of aquifer thermal energy storage (ATES) is of growing interest in the world. The technique is seen as an environmentally friendly and cheap solution for the purpose of heating and cooling large buildings. Research has shown that an ATES will have physical, chemical and biological consequences for the environment. This study assesses how the consequences
Development in sequencing technologies has made the analyses of genetic material much more accessible. Processing sequenced data for an accurate analysis comes with its challenges, especially with the studies in microbial in clinical in vivo samples where difficulties in the collection of these samples for sequencing could lower the quality and contamination from the human host which might affect
