Over-the-air multi-probe setups provide an efficient way to characterize the performance of today’s advanced wireless communication systems. In this paper the measurement uncertainty of such a setup using a car as a test object is characterized through three experiments: measurement system analysis, channel sounder measurements, and probe coupling measurements. Four issues were in focus for the an
A rapid method for the determination of the sum of free desmosine and isodesmosine in human plasma and urine is described. Efficient sample clean-up prior to LC-MS/MS analysis is mandatory for detection of free desmosines in plasma samples. The combination of ultra-filtration and a two-step solid phase extraction minimizes the sample complexity and ion suppression effects. The flow through from th
In cerebral palsy (CP) there is an increased risk of scoliosis. It is important to identify a progressive scoliosis early-on because the results of surgery depend on the magnitude of the curve. The Swedish follow-up program for cerebral palsy (CPUP) includes clinical examinations of the spine. The reliability and validity of the assessment method have not been studied. In this study we evaluate th
A well-founded decision needs to take into account as much information from a sample as possible. In gamma spectrometry, the number of photons and their energy are the two quantities readily accessible to the physicist and both should be used in order to increase the power of a statistical test. While the problem of counts of pulses has been much studied the problem of spectral distribution of pul
For many common global diseases, such as cancer, diabetes, neurodegenerative and cardiovascular diseases there is an unmet need for diagnosing early indications of disease that could enable medical intervention and early treatment. For example, cigarette smoking causes a variety of deadly diseases including lung cancer, hypertension, chronic obstructive pulmonary disease (COPD) and cardiovascular
Background: Early childhood environmental exposures, possibly infections, may be responsible for triggering islet autoimmunity and progression to type 1 diabetes (T1D). The Environmental Determinants of Diabetes in the Young (TEDDY) follows children with increased HLA-related genetic risk for future T1D. TEDDY asks parents to prospectively record the child's infections using a diary book. The pres
Background Smoking is a risk factor for the development of anti -citrullinated protein antibodies (ACPA) positive rheumatoid arthritis (RA). Whether smoking predisposes to severe joint damage progression is not known, since deleterious, protective and neutral observations have been made. Objective To determine the effect of smoking on joint damage progression. Methods Smoking status was assessed i
Pure rotational coherent anti-Stokes Raman scattering (CARS) spectra of N2O was recorded in a series of temperature calibrated cell measurements in the region 295-796K. A theoretical rotational CARS code for N2O was implemented and temperature analysis was performed by fitting the modeled theoretical spectra to the experimental spectra. Excellent agreement between the experimental and modeled spec
To validate cardiac output measurements by ultrasound dilution technology (COstatus monitor) against those obtained by a transit-time ultrasound technology with a perivascular flow probe and to investigate ultrasound dilution ability to estimate pulmonary to systemic blood flow ratio in children.
Objective. To identify predictors as free-text markers for mental ill-health from an electronic perinatal record (EMR) system and the association with emergency cesarean section (CS) in nulliparous women. Material and methods. This was a population-based study using an EMR system, set in the catchment area of Malmö University Hospital in Sweden. Of 10 662 nulliparous women presenting with a single
Background: Heavy-flavor production in p + p collisions is a good test of perturbative-quantum-chromodynamics (pQCD) calculations. Modification of heavy-flavor production in heavy-ion collisions relative to binary-collision scaling from p + p results, quantified with the nuclear-modification factor (R-AA), provides information on both cold-and hot-nuclear-matter effects. Midrapidity heavy-flavor R
Recent experiments on flapping flight in animals have shown that a variety of unrelated species shed a wake behind left and right wings consisting of both tip and root vortices. Here we present an investigation using Particle Image Velocimetry (PIV) of the behaviour and interaction of trailing vortices shed by paired, fixed wings that simplify and mimic the wake of a flying animal with a non-lifti
A cotton skin and a waterproof but permeable Gore-Tex skin were designed for the thermal manikin “Tore” to simulate different sweating styles (the wet cotton skin inside and Gore-Tex skin outside to simulate the sweating style of thermal manikin “Walter”, and Gore-Tex skin inside with wet cotton skin outside to simulate the sweating style of thermal manikins “Newton”). The evaporative resistances
This article discusses the advantages of the the Coherence Based Genealogical Method (CBGM), not only as a tool for reconstructing the text of the New Testament, but also for surveying the history of readings and for explaining textual changes. The CBGM promises to detect readings, which have emerged several times independently in the textual tradition. The method is applied to selected examples i
The results of a search for the production of second generation scalar leptoquarks are presented for final states consisting of either two muons and at least two jets or a muon plus missing transverse momentum and at least two jets. A total of 1.03 fb(-1) integrated luminosity of proton-proton collision data produced by the Large Hadron Collider at root s = 7 TeV and recorded by the ATLAS detector
The thesis explores the potential of one way of facilitating and stimulating collaboration in Library and Information Science (LIS), through a specific scientific collaboration activity: creating, sharing and reusing data collection instruments, such as interview guides, questionnaires, and observation protocols. The four studies reported in the thesis can be read as a linear narrative, each study
Objectives: To compare collagenase injections and surgery (fasciectomy) for Dupuytren's contracture (DC) regarding actual total direct treatment costs and short-term outcomes. Design: Retrospective cohort study. Setting: Orthopaedic department of a regional hospital in Sweden. Participants: Patients aged 65 years or older with previously untreated DC of 30 degrees or greater in the metacarpophalan
