Diffusion MRI (dMRI) has become an invaluable tool to assess the microstructural organization of brain tissue. Depending on the specific acquisition settings, the dMRI signal encodes specific properties of the underlying diffusion process. In the last two decades, several signal representations have been proposed to fit the dMRI signal and decode such properties. Most methods, however, are tested
The aim of this paper is to outline a process-based approach to the historical trajectory of commercialising cities that can account for continuity and change in a city’s image. Previous research involving historical approaches to the commercialisation of places are typically underpinned by a view of history as linear and chronological. By contrast, the present study adopts a performative view of
Involving professionals in research can ensure the acquisition of knowledge, that is relevant, applicable and sustainable. Professionals are people who work in health systems, or organisations that contribute to health systems, such as practitioners, managers or other decision-makers. They have context-specific knowledge which the researchers often lack. Therefore, when they are involved in resear
Laterally grown InxGa1-xAs nanowires (NWs) are promising candidates for radio frequency and quantum computing applications, which, however, can require atomic scale surface and interface control. This is challenging to obtain, not least due to ambient air exposure between fabrication steps, which induces surface oxidation. The geometric and electronic surface structures of InxGa1-xAs NWs and conta
Objective: To explore how cancer survivors have experienced their contacts with primary care after being diagnosed with cancer, focusing on the integration between cancer specialist and primary care, and participants’ views on what could make primary care services better at catering to the needs of cancer survivors. Design: A qualitative study in which data was collected through semi-structured di
The production of non-prompt D0 mesons from beauty-hadron decays was measured at midrapidity (|y| < 0.5) in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of sNN = 5.02 TeV with the ALICE experiment at the LHC. Their nuclear modification factor (RAA), measured for the first time down to pT = 1 GeV/c in the 0–10% and 30–50% centrality classes, indicates a significant suppression, up to
Objectives: The aim of this study was to investigate genetic outcomes, analyze the family experience, and describe the process of implementing genetic sequencing for children with profound sensorineural hearing loss (SNHL) at a tertial audiological center in southern Sweden. Design: This is a prospective pilot study including eleven children with profound bilateral SNHL who underwent cochlear impl
Many patients with outlet obstruction secondary to prostatic enlargement have lower urinary tract symptoms (LUTSs) and an increased frequency of micturition. The standard treatment is transurethral resection of the prostate (TURP), which alleviates obstruction and symptoms. However, after TURP, 20–40 percent of patients continue to experience LUTSs. The aim of the present study in rats was to iden
A measurement of elastic deeply virtual Compton scattering gamma*p --> gamma p using e(+) p and e(-) p collision data recorded with the HI detector at HERA is presented. The analysed data sample corresponds to an integrated luminosity of 306 pb(-1), almost equally shared between both beam charges. The cross section is measured as a function of the virtuality Q(2) of the exchanged photon and the ce
Direct ozone (O-3) injection is a promising flue-gas treatment technology based on oxidation of NO and Hg into soluble species like NO2, NO3, N2O5, oxidized mercury, etc. These product gases are then effectively removed from the flue gases with the wet flue gas desulfurization system for SO2. The kinetics and mixing behaviors of the oxidation process are important phenomena in development of pract
A semiconductor (InSb) showed transient metal- like heat conduction after excitation of a dense electron- hole plasma via short and intense light pulses. A related ultrafast strain relaxation was detected using picosecond time-resolved x-ray diffraction. The deduced heat conduction was, by a factor of 30, larger than the lattice contribution. The anomalously high heat conduction can be explained o
Objective: The 4.2-day half-life I-124 favors its use for positron emission tomography (PET) of monoclonal antibodies (mAbs). However, high positron energy and beta(+)-associated cascade gamma rays pose image resolution and background noise problems for I-124. This study evaluated quantitative PET of an I-124 mAb in tumor-bearing mice. Methods: An R4 microPET (TM) (Siemens/CTIMI, Knoxville, TN) wa
Ocean acidification, caused by the increased uptake of anthropogenic CO2, describes a change in the ocean’s carbonate chemistry. While its chemical processes are well understood, less is known about its biological and subsequently socio-economic consequences. However, there is evidence that marine organisms will be adversely affected by a decrease in pH and carbonate saturation levels. Fishery is
Pågående konflikter i Syrien, Afghanistan, Somalia och Sudan har inneburit att antalet flyktingar i världen stigit till nivåer som inte uppmäts på decennier. Barn och ungdomar utgör en stor del av de människor som befinner sig på flykt, varav vissa av dessa flyr ensamma utan stöd eller närvaro av föräldrar, syskon eller nära släktingar. I en svensk och internationell kontext benämns dessa barn somOngoing conflicts in Syria, Afghanistan, Somalia and Sudan has meant that the number of refugees worldwide has risen to levels not measured in decades. Children constitute a big part of these refugees, some of them fleeing their homes without a parent or a legal guardian. In a Swedish and international context these children are often referred to as ”unaccompanied”. This term referrers to the chil
Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications.

Populärvetenskaplig sammanfattning: Geologi är en ung gren av naturvetenskap. Det var inte förrän på 1800-talet som geologins ädla konst började diskuteras och detta trots att moral och religiös etik dikterade annat. Inte kunde väl jorden vara mer än 4000 år och borde inte Gud ha nämnt de där dinosaurierna i bibeln? Inte förrän mitten på 1900-talet började man till slut gräva fram ett och annat koThe mid-Atlantic ridge connects with land at the Reykjanes peninsula, Southwest Iceland. Iceland extends well over the whole ridge and allows for representative surface observations of sea-floor processes. Across the Peninsula the plate boundary is characterized by a rift zone, which encompasses leaky transform fault zone characteristics. Across a fissure swarm, connected with the Reykjanes volcan

GTS supplies about half a million different parts, which demands a large purchase organisation. This thesis deals with the so-called Sourcing purchase, which is a term for purchase of non-forecasted parts that have no
Förändras mikroorganismers ”samhällsstrukturer” över säsongen? Överallt i marken finns det mikroorganismer som servar växterna med näring, både i form av att de hjälper till att ta upp näring och dela med sig av, och genom att de bryter ner dött material och därmed gör näring tillgänglig.

As almost three out of four EU citizens live in urban areas and this number is expected to further grow, studies on urban ecosystems and their services are crucial to understand a city’s environmental structure and capabilities. The European Commission has published a relative report which suggests an urban ecosystem condition indicator framework, yet without suggesting respective thresholds tha
Elektromagnetiska vågor, även kända som radiovågor, är vågor som sprider sig med låga frekvenser från 3 till 30 kHz. Dessa lågfrekventa vågor används vanligtvis när man önskar kommunicera med ubåtar. De kan emellertid också användas på land för att mäta skillnader i jord– och bergarters elektriska konduktivitet. Denna mätteknik kallas Very-Low-Frequency Electromagnetics (VLF-EM) och har framgångsrElectromagnetic waves, also known as radio waves, which propagate at low frequencies of only 3 kHz to 30 kHz, are usually used for communication with submarines. However, these waves can also be used on land to measure differences in the electrical conductivity of the subsurface. This technique is called Very-Low-Frequency Electromagnetics (VLF-EM) and has been successfully used to gain an insight
