A search for strongly produced supersymmetric particles using signatures involving multiple energetic jets and either two isolated same-sign leptons (e or μ), or at least three isolated leptons, is presented. The analysis relies on the identification of b-jets and high missing transverse momentum to achieve good sensitivity. A data sample of proton-proton collisions at s=13 TeV recorded with the A
Background: In order to save potable water, this study aims to evaluate the contamination of soil and Capsicum annuum L. (chilli) watered with urban wastewater (sewage) pre-treated by various wetland systems. Methods: The appropriateness of wetland outflow for irrigation when applying reused wastewater with high contamination of minerals and pathogens was assessed. The impact of wastewaters pre-tr
BACKGROUND: Intracerebral microdialysis (MD) was applied in patients with severe subarachnoid haemorrhage treated in a neurosurgical intensive care unit in order to explore their cerebral energy metabolism.METHOD: Brain MD fluid levels of glucose, lactate and pyruvate were measured for 3 to 12 days in 20 patients and 2,635 hourly samples were analysed. The MD data were related to computerized tomo
Conceptual models of aquifer systems can be refined and complemented with geophysical data, and they can assist in understanding hydrogeological properties such as groundwater storage capacity. This research attempts to use geoelectrical methods, Electrical Resistivity Tomography and Induced Polarization parameters, for mapping the subsurface in alluvial fans and to demonstrate its applicability;
Through a unique combination of time-resolved single-molecule (cryo-TEM) and bulk measurements (light scattering and small-angle X-ray scattering), we provide a detailed study of the dynamics of stochastic DNA ejection events from phage λ. We reveal that both binding with the specific phage receptor, LamB, and thermo-mechanical destabilization of the portal vertex on the capsid are required for in
Grapes are culturally a new crop in the Swedish landscape, which demands an introduction period concerning development of knowledge about how to grow the wine. Climate changes together with the development of "cross breeding" in Vitis vinifera open up new possibilities with new grapes, that previously were not possible to grow commercially and that suits the Swedish consumers. Wine production is o
Shaken baby syndrome has typically been associated with findings of subdural haematoma, retinal haemorrhages and encephalopathy, which are referred to as the triad. During the last decade, however, the certainty with which the triad can indicate that an infant has been violently shaken has been increasingly questioned. The aim of this study was to determine the diagnostic accuracy of the triad in
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 comparative risk assessment (CRA) is a comprehensive approach to risk factor quantification that offers a useful tool for synthesising evidence on risks and risk-outcome associations. With each annual GBD study, we update the GBD CRA to incorporate improved methods, new risks and risk-outcome pairs, and new data
True comorbidity is the independent occurrence of more than one disease in a patient. In a disease like systemic sclerosis (SSc) which involves almost all organs, it is problematic to define comorbidity. A good example is SSc and primary Sjögren's disease. Figures as high as 80% comorbidity have been published, but in the majority it may be caused by fibrosis and not inflammation and thus should b
In two miniature artificial language learning experiments, we compare the processing of narrow and broad negation, corresponding to prefixal negation (unhappy) and free-standing negation (not happy) respectively, with that of non-negation (happy). Three artificial prefixes were invented to express the three meanings above. The meaning scope expressed by the negation types was manipulated in the ex
A new mean-field theory is developed to treat a binary mixture of nanoparticles imbedded in a polydisperse polymer solution. The theory is based on a many-body polymer-mediated potential of mean force (PMF) between the particles and remains accurate even in the protein regime, where the particles' diameters cannot necessarily be considered large compared to the polymer radius of gyration. As imple
The composition of the dominating population of freshly cut beef, and beef stored at 4 degrees C for 8 d, was studied by direct analysis of the 16S rRNA gene (PCR amplification, cloning and sequencing) and compared with pure culture technique where the isolates picked from the viable plate count were identified by sequencing of the 16S rRNA gene. The composition of the bacterial population was rec
Consider a reflected random walk Wn+1 = (W-n +X-n)(+), where X-o, X-1,... are i.i.d. with negative mean and subexponential with common distribution F. It is shown that the probability that the maximum within a regenerative cycle with mean mu exceeds x is approximately mu (F) over bar(x) as x --> infinity, and thereby that max (W-o,..., W-n) has the same asymptotics as max(X-o,...,X-n) as n --> inf
From the point of view of each individual’s sense-making, an organization is an emergent property of inter-individual sense-making processes and activities. The organization is a result of emergence from individual sense-making perspectives. A critically informed approach to research involves recognition / understanding of this emergence. Without the recognition of the uniqueness of each particula
Most nuclear medicine clinicians use only visual assessment when interpreting regional cerebral blood flow (rCBF) from single-photon emission computed tomography (SPECT) images in clinical practice. The aims of this study were to develop a new, easy to use, automated method for quantification of rCBF-SPECT and to create normal values by using the method on a normal population. We developed a 3-dim
BACKGROUND: In locally advanced rectal cancer, 5-Fluorouracil (5-FU)-based chemoradiation is the standard treatment. The main acute toxicity of this treatment is enteritis. Due to its potential radiosensitizing properties, oxaliplatin has recently been incorporated in many clinical chemoradiation protocols. The aim of this study was to investigate to what extent 5-FU and oxaliplatin influence the
Popular Abstract in Swedish Denna avhandling behandlar modellsystem för farmaka som har DNA och RNA som mål i cellen. Framförallt behandlar den hur strukturen hos DNA och RNA påverkas av inbindning av olika substanser, samt hur fort denna inbindning sker. Tre olika typer av farmaka behandlas: 1. Platinaföreningar som länge använts som cytostatika, 2. RNA interferens som främst har utvecklats undDrugs targeting nucleic acids were studied in DNA and RNA model systems. The effects were investigated with respect to structural and thermodynamic influence, kinetics, and biological function. The drugs employed in this thesis were anticancer active platinum(II) complexes, polyamine derivatives, and siRNA. Structural changes were determined by use of chemical probing and circular dichroism (CD),
Electric Hybrid Vehicles, EHV, are under development to provide lower fuel consumption levels and minimize the environmental pollution compared to pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more complex and thus carry many more extra parts than the pure ICE based vehicle. Competing against the pure ICE vehicle in the sense of nonexpensive mass production is hard. This thesis
Popular Abstract in SwedishEtt väl etablerat fynd inom personbedömningsforskning är att vi människor bedömer varandra på ett mer nyanserat sätt än enbart en endimensionell skala (bra-dålig). Istället använder vi oss av två grundläggande dimensioner för personbedömningar. Den första dimensionen (värme) ger oss svaret på andra människors avsikter (t.ex. vänligt eller fientligt inställda till oss). DIt is well established that we do not judge other people on a one-dimensional scale (i.e., good - bad), but rather based on two fundamental dimensions. The first dimension is warmth, which essentially answers the questions of what the other person’s intentions are (e.g., friendly or malicious). The second dimension is competence, which in contrast answers the question regarding the person’s capabi
Observations of sea level and precipitation in Malmö, Sweden in the southeastern part of the sound Öresund have been used to estimate the probabilities of local compound events of high sea level and large daily and hourly rains. There are observations of sea level and daily rains extending back to 1930. The observations of short-term rainfall are from 1980 and onwards. Most large rainfalls come in
