Från linjär till cirkulär offentlig upphandling - En fallstudie av fem kommuner och deras arbete och vad som står i vägen för utvecklingen Vårt levnadssätt där linjär ekonomi med slit och släng är norm är ohållbart för att uppnå klimatmålen och målen i agenda 2030. Offentlig upphandling har en stor roll i denna omställning och kan med hjälp av rätt strategier börja göra upphandlingar med produkterSwedish municipalities can play a key role in contributing to the circular economy through public procurement as this is responsible for the emission of 23 million tons of carbon dioxide each year. Previous studies indicate that there is a need of developing dialogues involving all actors to increase the knowledge concerning why circular products are needed. The aim of this study was to investigat

3D-models of bone structures from computed tomography (CT) data can be used for surgical planning, education and a wide range of other purposes. They can also be used in both digital and 3D-printed format. The currently used process to obtain such models consists of a combination of thresholding, morphological operations and manual adjustments. This can be very time-consuming. Deep Learning (DL) c

Metodutveckling för analys av cellulärt upptag av nanopartiklar Cancer är idag en utbredd sjukdom som tusentals människor världen över diagnostiseras för dagligen. Möjligheterna att få en korrekt behandling ökar om tumörer upptäcks i ett tidigt skede tidigt vilket ger en större chans att tillfriskna. Men detta har visat sig vara en utmaning då nuvarande metoder som används inte är av tillräckligAbstract MRI, magnetic resonance imaging, is used for disease detection such as assessing blood flow, detecting tumours and diagnosing many forms of cancer. Contrast agents are chemical substances that increase the MRI sensitivity. One class of contrast agents are the so called nanoparticulate contrast agents. Since tumour-associated formation of new blood vessels often results in highly permeab

När Lissabonfördraget trädde i kraft den 1 december 2009 medförde det viktiga förändringar inom EU:s utrikespolitik. Målet var att öka EU:s samstämmighet i dess externa relationer i syfte att stärka EU:s roll som global aktör. Det nya fördraget inrättade en hög representant för den gemensamma utrikes-och säkerhetspolitiken (HR) samt en assisterande utrikestjänst (EEAS). De nya funktionerna är histThe entry into force of the Lisbon Treaty in December 2009 brought several important changes in the field of EU Foreign Policy. The goal was to enhance coherence in EU external relations to strengthen the role of the EU as a global actor. The creations of the High Representative (HR) of the Union on Foreign Affairs and Security Policy and the assisting European External Action Service (EEAS) are t

Electronic Medical Records (EMR) is the vital and basic part of construction digitizing hospital. However the systems are well-known for their interoperability problems and a Swedish evaluation from 2010 concluded it to be the most frequent obstacle in workflow. We then wondered what techniques the organizations used to solve the problem to understand if the organizations use the right solution to

One of the biggest expenses for airline companies is the fuel for the aircrafts; preceded only by labor costs it is important for an airline to optimize its use of fuel. One option to save money on fuel is by doing something called Fuel Tankering. Essentially, fuel tankering is a way to lower the fuel cost by refueling at departures where the fuel price is lower than at the destination of the airc

Abstract Authors: Tina Olofsson och Ida Linderoth. Title:”Where is the support?” A qualitative study of support services for families with youths suffering from self-harming behavior. Supervisor: Stig Linde Assessor: Carina Tigervall The aim of this study was to examine which type of support the families in our study expressed that they were in need of during the time their youths had a self-ha

The activity of heterotrophic soil microorganisms is usually limited by the availability and quality of carbon (C). Adding organic substances will thus trigger a microbial response. We studied the response in bacterial growth and respiration after the addition of low amounts of glucose. First we determined if additions of glucose, at concentrations which did not result in an exponential increase i

In temperate regions, many vector-borne parasites maximise their transmission prospects by adjusting reproduction to seasonal cycles of host susceptibility and vector availability. Nevertheless, in these regions there are areas where environmental conditions are favourable throughout the year, so that parasites could benefit from a year-round transmission strategy. We analysed how different transm

A capture-mark-recapture study on the threatened saproxylic beetle Lucanus cervus was carried out in a chestnut (Castanea sativa) woodland located in northern Italy, using visual encounter surveys (VES) as well as aerial flight interception traps and pitfall traps (PT), both of which were baited with different odour lures. In total, 111 males and 25 females were captured, and VES was by far the mo

Modern industrial robots are traditionally programmed to follow desired trajectories, with the only feedback coming from the internal position/angle sensors in the joints. The robots are in general very accurate in tracking the desired motion, and they have become indispensable in many applications, such as spot welding and painting in the automotive industry. In more complex tasks, such as physic

Negative pressure wound therapy (NPWT) has become widely adopted over the last 15 years and over 1000 peer reviewed publications are available describing its use. Despite this, there remains uncertainty regarding several aspects of usage. In order to respond to this gap a global expert panel was convened to develop evidence-based recommendations describing the use of NPWT. In this paper the result

Arteriosclerosis with its clinical sequelae (cardiac infarction, stroke, peripheral arterial occlusive disease) and vascular/Alzheimer dementia not only result in far more than half of all deaths but also represent dramatic economic problems. The reason is, among others, that diabetes mellitus is an independent risk factor for both disorders, and the number of diabetics strongly increases worldwid

We compiled the available information on the occurrence and timing of migratory bat activity across the Baltic Sea and south-eastern North Sea coasts and islands, based on ultrasonic monitoring projects at 19 localities in 2007-2009. The data refer to three species; Nathusius' pipistrelle Pipistrellus nathusii, soprano pipistrelle P. pygmaeus and common noctule Nyctalus noctula. Pipistrellus nathu

Mass-propagation of the spruce bark beetle, Ips typographus, following windfalls and drought is a serious threat to mature spruce forests. Climate change will affect the population dynamics of I. typographus directly as the swarming activity and development rate are mainly controlled by temperature, and indirectly via changes in availability of brood trees. Today, I. typographus is in general univ

The nitrate reductase activity (NRA) was measured during spring, early summer and late summer in three deciduous forests, where the tree layer was dominated by oak. The nitrate assimilation capacities of the compartments of the above-ground and below-ground biomass of the understory and of the leaves and roots of the tree layer were calculated as NRA per unit biomass and NRA per unit area. The NRA

The 2004 Merger Regulation introduced a change to the substantive test for the Commission's intervention in mergers. The Commission is now able to block mergers which significantly impede effective competition in the EC. The purpose of the change was to guarantee that the Commission could deal with all harmful effects to competition resulting from a merger. More specifically, the purpose was t

The large international variation in the incidence of prostate cancer (PC) is well known but the underlying reasons are not understood. We want to compare PC incidence and survival among immigrants to Sweden in order to explain the international differences. Cancer data were obtained from the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for PC in first-degree immig

Non-invasive vascular studies can provide crucial information on the presence, location, and severity of critical limb ischaemia (CLI), as well as the initial assessment or treatment planning. Ankle-brachial index with Doppler ultrasound, despite limitations in diabetic and end-stage renal failure patients, is the first-line evaluation of CLI. In this group of patients, toe-brachial index measurem
