The degree of trophic specialization determines the ability of predators to cope with changing foraging conditions, but in predators that prey on hundreds of species it is challenging to assess, especially when prey identity varies among predator individuals and across space and time. Here, we test the hypothesis that a bat species foraging on flying insects like moths will show ample flexibility
Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maxim
Traumatic brain injury (TBI) often leads to impaired regulation of cerebral blood flow, which may be caused by pathological changes of the vascular smooth muscle cells (VSMCs) in the arterial wall. Moreover, these cerebrovascular changes may contribute to the development of various neurodegenerative disorders such as Alzheimer’s-like pathologies that include amyloid beta aggregation. Despite its i
Autopsy data indicate that the locus coeruleus (LC) is one of the first sites in the brain to accumulate hyperphosphorylated tau pathology, with the rostral part possibly being more vulnerable in the earlier stages of the disease. Taking advantage of recent developments in ultra-high field (7 T) imaging, we investigated whether imaging measures of the LC also reveal a specific anatomic correlation
Avhandlingen undersöker föreningar i Sverige som organiserar öppna verkstäder. Öppna verkstäder, vilka också kallas för makerspaces, är platser som möjliggör skapande. Verktyg, maskiner och kunskap är delade mellan användarna. Syftet med avhandlingen är att undersöka hur föreningar organiserar sina delade verkstäder, vilka svårigheter föreningarna möter samt vilka implikationer detta har för den bAlternative building as an interstitial mode of transformation plays a central role in the discussion of strategies for degrowth. In this debate the questions of how alternative projects can be scaled up and how degrowth politics can gain broad societal support have been identified as crucial. In this context open workshops – grassroots infrastructures for creative activities, such as repair, upcy
Elevated air temperature and atmospheric vapor pressure deficit (VPD) are key drivers of plant physiological and ecological processes. However, their relative impacts on vegetation productivity remain difficult to isolate due to the strong coupling between them. This coupling complicates efforts to disentangle independent effects, particularly under compound drought conditions at regional or globa
Landscape fragmentation and decreasing habitat areas poses a threat to biodiversity worldwide. Green infrastructure has developed as a conservation approach promoting habitat connectivity on a landscape scale. However, green infrastructure is much more than a network of natural structures and elements enabling species movement. It represents a new mode in environmental protection policy, addressin
Under början av 1900-talet var illegala aborter ett samhällsproblem i Sverige. Fosterfördrivning var straffbelagt, kvinnor som blivit ovilligt gravida stod därför inför valet att antingen föda barnet eller genomföra abort på egen hand. År 1939 trädde den första lagen på området, lagen om avbrytande av havandeskap, 1938 års lag, i kraft. Lagen tillämpades mycket restriktivt och antalet illegala aboIllegal abortions were a social issue in Sweden during the 20th century. Abortions were punishable, and therefore a woman who became pregnant against her will stood before the choice of either unwillingly giving birth or carrying out an abortion on her own. In 1939 the first law on abortions came into force. The law was restrictively interpreted and the number of illegal abortions continued to inc
Av artikel 6 Europakonventionen följer att varje person som befinner sig under en medlemsstats jurisdiktion har rätt till en rättvis rättegång. Till de rättigheter som i detta avseende följer tillkommer bland annat oskyldighetspresumtionen som medför att varje person som står anklagad för brott försäkras att betraktas som oskyldig till att motsatsen bevisas och dennes skuld lagligen fastställts. OArticle 6 in the European Convention on Human Right provides that every person under the jurisdiction of a member state has the right to a fair trial. To the rights that follow in this respect are added, among other things, the presumption of innocence, which means that every person accused of a crime is assured to be considered innocent until proven guilty and his guilt legally establishes. The i
More than 400 million people in the world have type 2 diabetes, making it one of the most common diseases internationally according to the World Health Organization. Thiazolidinediones (TZDs) is used to treat type 2 diabetes since it increases the sensitivity of insulin in peripheral tissues. The knowledge about the mechanism how TZD works is limited which has resulted in patients getting serious
Purpose/Background Dual Energy Computed Tomography (DECT) have been clinically available for over ten years. Two such systems are currently used at Skane University Hospital (SUS) in Lund. By utilizing materials different attenuating properties at different energies, material decomposition and iodine quantification is possible. The aim of this master thesis was to compare the two DECT systems and
Behovet av att skapa hållbara och flexibla byggnader har vuxit under de senaste åren, inte minst för att möta högt uppsatta klimatmål. Utrymmena mellan byggnaderna, med andra ord utemiljöer, har regelbundet prioriterats sekundärt och anpassats i stor utsträckning efter det bebyggda behovet. Utemiljöer i urban kontext innehåller ofta mer eller mindre kollektiva varor, som är icke-exkluderbara och iThe need for sustainable and flexible buildings has grown in recent years in order to meet climate goals. However, outdoor environments have often been overlooked and is often strongly controlled by the built environment. These spaces hold significant social and ecological benefits but pose challenges for real estate companies as they lack direct financial returns. Well-designed outdoor environme
In the design of a building there are many parameters that effect the material efficiency. The choice of structural solution and material are two of the parameters that will be investigated further in this rapport. Suspension structures is one type of structural solution that has high material efficiency, here the bending stiff properties of timber could also be utilized in order to increase the s
Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. This thesis aims to optimise the CBCT image reconstruction protocol in MuriSlice to enable the segmentation of CBCT images
The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. For a carton this is defined by the repulpability, i.e., the ab
Notwithstanding the increasing environmental awareness among consumers, researchers do not witness a substantial shift in consumption and disposal behaviour of textiles. Since research on disposal behaviour of home textile products is currently limited, it is relevant to explore consumers’ decision-making when handling no-longer-wanted home textiles. This thesis aims to better understand consumers
Today world’s cities are in a state of flux exhibiting complex dynamics and at the core of sustainability challenges including climate change and urbanization. At the same time cities have been acknowledged as agents of change when it comes to addressing these challenges. The urgency to address these problems has triggered cities to find smarter and innovative ways to deal with these challenges. C
Klimatet under Kvartärperioden har dominerats av återkommande istider, då bl.a. Skandinavien och Sverige varit täckt av inlandsis. Vid analysen av långsiktig säkerhet för det planerade förvaret av använt kärnbränsle, i Sverige, behöver tider på upp till en miljon år beaktas. Under denna mycket långa tid förväntas nya nedisningar komma och därför utförs ett forskningsprogram på Grönland för att ökaDuring the Quaternary period, the climate has been dominated by glacial cycles resulting in periodic ice sheet coverage over Scandinavia and Sweden. In the scenarios for future climate development used in the assessment of long-term safety for planned repository of spent nuclear fuel, the possibility of future glaciations need to be considered. The present study is part of a larger hydrological st
Trots ett flertal överväganden om införande av en samtyckesreglering, har debatten kring en sådan reglering och våldtäktsbestämmelsen aldrig avstannat. Detta är ett ämne som väcker starka känslor, samt engagerar allmänheten och media i debatten. Flera sexualbrottsutredningar har tillsatts för att på uppdrag av regeringen utreda om en samtyckesreglering borde införas i den svenska lagstiftningen fDespite numerous deliberations of introducing a consent-based legislation, the debate has never ceased. This is a subject that evokes strong emotions among the public and media, which engages them in the debate. Several Sexual Offences Commissions have been assigned by the Government to investigate whether a consent-based regulation should be passed as law to reinforce the right to sexual self-de
An object in an external magnetic field will be magnetized and the degree of magnetization is dependent of the magnetic susceptibility of the object. The local magnetic field inside and around an object in the MR scanner will change due to the magnetization of the object. The phase shift is proportional to the local magnetic field, which means that phase images hold information about the susceptib
