Methane and carbon dioxide fluxes over a lake : Comparison between eddy covariance, floating chambers and boundary layer method

Freshwaters bring a notable contribution to the global carbon budget by emitting both carbon dioxide (CO2) and methane (CH4) to the atmosphere. Global estimates of freshwater emissions traditionally use a wind-speed-based gas transfer velocity, kCC (introduced by Cole and Caraco, 1998), for calculating diffusive flux with the boundary layer method (BLM). We compared CH4 and CO2 fluxes from BLM wit

Polygenic pathways shape white matter vulnerability to Alzheimer’s disease-related pathophysiological changes

Background: The accumulation of amyloid-β1−42 (Aβ1−42) peptides and phosphorylated-Tau181 (p-Tau181) tangles from the preclinical stages of Alzheimer’s disease (AD) has led to a biological definition of the disease. However, among Aβ1−42-positive individuals, cognitive decline onset varies, and some never develop symptoms. Genetic influences on molecular pathways and their interactions with protei

Calculation and Measurement Methods for the Performance of Solar Collectors. Models of Flat Plate Collectors, Transparent Insulation and Efficiency Factors.

Popular Abstract in Swedish Denna avhandling handlar om modeller för plana solfångare, transparent isolering och verkningsgradsfaktorer. En ekvation för energiutbytet från en glasad plan solfångare härleds genom att modellera verkningsgradsfaktorn, F´, som en summa av en konstant och en temperaturberoende del. Ett alternativt sätt att testa en plan solfångare, baserat på denna modell, föreslås. EThis thesis deals with models of flat plate collectors, transparent insulation and efficiency factors. An equation for the energy output from a glazed flat plate collector is derived by modelling the collector efficiency factor, F´ as the sum of a constant and a temperature dependent part. An alternative way of testing a flat plate collector, based on this model, is suggested. A complete set of a

Enhancing the Accuracy of CSI-Based Positioning in Massive MIMO Systems

Massive Multiple-Input Multiple-Output (MIMO) communication systems are being investigated intensively for positioning services. Enhancing the accuracy on these services in terms of accurate positioning of users is an important goal to improve related applications in the future. Convolutional Neural Networks (CNNs) has been proposed to infer the position of a user from Channel State Information (C

Arsine, Stibine and Phosphine Derivatives of [Fe2(CO)6(μ-bdt)] (bdt = Benzenedithiolate) : Syntheses, Structures and Spectroscopic and Electrocatalytic Studies

The reactivity of the benzenedithiolate (bdt)-bridged complex [Fe2(CO)6(µ-bdt)] with arsine, stibine and phosphine ligands has been studied. The new mono- and disubstituted complexes [Fe2(CO)5(EPh3)(µ-bdt)] (E = As, 1; E = Sb 3) and [Fe2(CO)4(EPh3)2(µ-bdt)] (E = As, 2; E = Sb, 4) and the previously reported [Fe2(CO)4(PPh2H)2(µ-bdt)] (5) have been prepared by Me3NO-initiated carbonyl substitution r

Homozygosity for the IgG2 subclass allotype G2M(n) protects against severe infection in hereditary C2 deficiency

Homozygous C2 deficiency (C2D) is the most common deficiency of the classical complement pathway in Western countries. It is mostly found in patients with autoimmune disease or susceptibility to bacterial infections and in healthy persons. We wished to assess to what extent other immunological factors might explain differences of susceptibility to infections in C2D. For this reason, 44 Swedish pat

The IgG-degrading enzyme of Streptococcus pyogenes causes rapid clearance of anti-glomerular basement membrane antibodies in patients with refractory anti-glomerular basement membrane disease

In anti-glomerular basement membrane (anti-GBM) disease, IgG class autoantibodies induce rapidly progressive glomerulonephritis. Regrettably, many patients are diagnosed at a late stage when even intensive conventional treatment fails to restore renal function The endopeptidase IdeS (Immunoglobulin G degrading enzyme of Streptococcus pyogenes) (imliflidase) rapidly cleaves all human IgG subclasses

The derivation of first- and second-order backpropagation methods for fully-connected and convolutional neural networks

We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. The partial derivatives in the chain rule formula are rela

Möten på Barn- & Ungdomssjukhuset i Lund

Hospital. Not a positive word. Children + Hospital. Create an even more unpleasant feeling. When you arrive to the Children´s Hospital in Lund, you enter a dark but wide corridor. A busy doctor may scurry across the fl oor and disappear behind an alarmed door. If the reception is unmanned, the grey metallic venetian blinds are closed. It is hard to understand where to go. Even a grown-up can feel

Surface proteins of pathogenic streptococci

Popular Abstract in Swedish Grupp B streptokocker (GBS; Streptococcus agalactiae) är den vanligaste orsaken till livs-hotande infektioner hos nyfödda barn. Enbart i USA orsakar GBS ~10 000 fall av meningit (hjärnhinneinflammation), pneumoni (lunginflammation) och sepsis (blodförgiftning) varje år. Infektionerna har hög dödlighet och en stor del av de barn som överlever infektionerna får bestående Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity.

Lab-scale versus industrial-scale thermal runaway tests for lithium-ion battery cells

Lithium-ion battery safety is a topic of large importance, and testing is associated with large costs. Safety evaluation is therefore needed also at an early stage in cell design and development, in order to evaluate potential short-comings or to screen large platforms of materials and cells. Previous thermal runaway tests on lab-scale cells have, however, indicated differences in heat release and

Efficacy of T-cell assays for the diagnosis of primary defects in cytotoxic lymphocyte exocytosis

Primary hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disorder associated with autosomal recessive variants in genes required for perforin-mediated lymphocyte cytotoxicity. A rapid diagnosis is crucial for successful treatment. Although defective cytotoxic T lymphocyte (CTL) function causes pathogenesis, quantification of natural killer (NK)–cell exocytosis triggered by K562 targe

Structural determination of Streptococcus pyogenes M1 protein interactions with human immunoglobulin G using integrative structural biology

Streptococcus pyogenes (Group A streptococcus; GAS) is an important human pathogen responsible for mild to severe, life-threatening infections. GAS expresses a wide range of virulence factors, including the M family proteins. The M proteins allow the bacteria to evade parts of the human immune defenses by triggering the formation of a dense coat of plasma proteins surrounding the bacteria, includi
