Frågor kring tillit i det digitala, tycks det, ställs oftare och oftare: Hur ska vi hantera integritets- och övervakningsfrågor? Hur ska vi hantera den mätbarhet som följer av vår digitaliserade tillvaro? Vad är det som avgör vilka tjänster vi litar på och vilka vi inte litar på, i vilken mån spelar den tekniska säkerheten en roll? Liknande frågor kan ställas om vilka kunskapsinstitutioner vi lita
Popular Abstract in Swedish Vid hjärtsvikt är hjärtats pumpförmåga nedsatt och kroppens vävnader kan ej förses med tillräckligt mycket blod utan kompensatoriska förändringar i kroppen. Dessa kompensationsmekanismer är kortvarigt ändamålsenliga men skjuter snabbt över målet vid hjärtsvikt och förvärrar istället symptomen. Under de senaste åren har behandlingen av hjärtsvikt därför kommit att inriktAngiotensin-converting enzyme (ACE) inhibitors act by decreasing production of angiotensin II and by potentiating the effects of bradykinin by inhibition of its breakdown. Bradykinin exerts part of its effects via vasodilating prostaglandins. Since the cyclooxygenase (COX)-inhibitors, e.g. aspirin and non-steroidal anti-inflammatory drugs, NSAIDs, block the formation of prostaglandins patients may
After the enthusiastic celebration of the 20th Anniversary of the Montreal Protocol on Substances that Deplete the Ozone Layer in 2007, the work for the protection of the ozone layer continues. The Environmental Effects Assessment Panel is one of the three expert panels within theMontreal Protocol. This “EEAP” deals with the increase of the UV irradiance on the Earth’s surface and its effects on h
We studied a ca 200 ha large forest site that holds an exceptionally large number of red-listed saproxylic beetles. We conducted pollen, charcoal and dendroecological analyses to reveal the long-term stand-level history of the site. We also investigated which of the red-listed saproxylic beetles recorded at the site are probably dependent on forest fires or structures that are created by fires. Po
Ga1-xMnx As is commonly considered as a promising material for microelectronic applications utilizing the electron spin. One of the ways that allow increasing the Curie temperature above room temperature is to produce second phase inclusions. In this paper Gal-,Mn.As samples containing precipitations of ferromagnetic MnAs are under consideration. We focus on the atomic and electronic structure aro
The classical Stern-Gerlach experiment is analyzed with an emphasis on the spin dynamics. The central question asked is whether there occurs a relaxation of the spin angular momentum during the time the particle passes through the Stern-Gerlach magnet. We examine in particular the transverse relaxation, involving angular momentum exchange between the spin of the particles and the spins of the magn
Background: Real-time perfusion (RTP) contrast echocardiography can be used during adenosine stress echocardiography (ASE) to evaluate myocardial ischemia. We compared two different types of RTP power modulation techniques, angiomode (AM) and high-resolution grayscale (HR), with Tc-99m-tetrofosmin single-photon emission computed tomography (SPECT) for the detection of myocardial ischemia. Methods:
Ditrysia comprise close to 99 % of all butterflies and moths. The evolutionary relationships among the ditrysian superfamilies have received considerable attention in phylogenetic studies based on DNA and transcriptomic data, but the deepest divergences remain for large parts unresolved or contradictory. To obtain complementary insight into the evolutionary history of the clade, and to test previo
Our study had three objectives: to extend the plasmid-based transformation protocol to a clinical isolate of C. trachomatis belonging to the trachoma biovar, to provide "proof of principle'' that it is possible to "knock out'' selected plasmid genes (retaining a replication competent plasmid) and to investigate the plasticity of the plasmid. A recently developed, plasmid-based transformation proto
Jag skrev om en föreslagen ändring i Brottsbalken (BrB)som syftar till att komplettera kriminaliseringen av "våldtäkt" och "sexuellt tvång" med en paragraf som riktar sig mot "sexuellt övergrepp". Den nya paragrafen ska innebära att en person som företar en sexuell handling mot en annan person mot dennas vilja ska straffas oavsett övriga omständigheter. Jag ville disI wrote about a new proposition to the Swedish Penal Code (BrB) which has the purpose to complement the paragraphs regarding rape (”våldtäkt”) and sexual force (”sexuellt tvång”) with the crime sexual assault (”sexuellt övergrepp”). The new crime will imply that a person who undertakes a sexual action onto another person without the consent of that person will be punished. I wanted to discuss th
The demand for energy in the world is increasing steadily. As the standard of living for people in the developing countries is increasing so is the net energy use per capita. The main contributor to the energy consumption is the use of fossil fuels, which is also the major emission source for carbon dioxide. Carbon dioxide is in turn one of the most significant greenhouse gases and will enhance te
Populärvetenskaplig sammanfattning: Naturbetesmarkerna minskade med 86,7% från 1927 till 1990. Denna minskning är alarmerande eftersom många idag hotade och sällsynta arter är beroende av dessa. En stor del av anledningen till detta är att staten ända in på 1980-talet i sin rådgivning danade för att dessa marker antingen skulle bearbetas med konstgödsel och ogräsbekämpning eller planteras med trädThe rural landscape of Sweden has changed rapidly during the 20:th century. Measurements from 1927 compared to those from 1990 show that the area of non managed pasture in Sweden has declined by 86.7 %. Since a lot of threatened and rare species are dependent of this kind of land, these figures are alarming. During the last 30-40 years non managed pasture has declined due to abandonment, tree plan
In this seventh edition of the Excellent MSc Dissertation series, four students present condensed versions of their Master’s theses, completed for the MSc degree in Media and Communication Studies at Lund University. Separately and together, the four contributions in this book exemplify what staff at the Department of Communication and Media consider to comprise an excellent dissertation at the Ma
Intraventricular hemorrhage (IVH) is one of the major co-morbidities of premature birth associated with post-hemorrhagic ventricular dilatation (PHVD) development, long-term neurodevelopmental impairment, behavioral problems, special educational needs, and dependency on social security.Hypothesis and aims: We believe that extravasated blood and further release of extracellular hemoglobin (Hb) are
BACKGROUND: Chronic subdural hematoma (CSDH) is one of the most common neurosurgical diseases. In surgical management of CSDH, there is a lack of standardized guidelines concerning surgical techniques and a lack of consensus on which technique(s) are optimal. Neurosurgical centers have shown a wide variation in surgical techniques. The purpose of this study was to compare two different surgical te
Background: There is an evident discrepancy between need and provision of evidence-based return-to-work (RTW) interventions in existing mental health services. Online dissemination of evidence-based interventions is presumed to reduce this gap. However, there is almost no knowledge available on perceived acceptability of digital RTW interventions among service users, which are factors that might i
The concept of the Z-scheme of oxygenic photosynthesis is in all the textbooks. However, its evolution is not. We focus here mainly on some of the history of its biophysical aspects. We have arbitrarily divided here the 1941–2016 period into three sub-periods: (a) Origin of the concept of two light reactions: first hinted at, in 1941, by James Franck and Karl Herzfeld; described and explained, in
Background Intracellular delivery of antimicrobial agents by nanoparticles, such as mesoporous silica particles (MSPs), offers an interesting strategy to treat intracellular infections. In tuberculosis (TB), Mycobacterium tuberculosis avoids components of the immune system by residing primarily inside alveolar macrophages, which are the desired target for TB therapy. Methods and findings We have p
