Time resolved, 3D imaging (4D) of two phase flow at a repetition rate of 1 kHz

A measurement technique capable of recording three-dimensional laser induced images with a spatial resolution of 610x512x20 voxels over a volume of 29x24x15 mm(3) and at a frame rate of 1 kHz is presented. A novel approach for sweeping the illuminating laser sheet across the investigated volume is introduced as a key feature. The technique is applied to imaging nebulized water droplets with a nitr

Phylogenetic Patterns of Human Coxsackievirus B5 Arise from Population Dynamics between Two Genogroups and Reveal Evolutionary Factors of Molecular Adaptation and Transmission

The aim of this study was to gain insights into the tempo and mode of the evolutionary processes that sustain genetic diversity in coxsackievirus B5 (CVB5) and into the interplay with virus transmission. We estimated phylodynamic patterns with a large sample of virus strains collected in Europe by Bayesian statistical methods, reconstructed the ancestral states of genealogical nodes, and tested fo

Job satisfaction, strain and stress of conscience among nurse assistants working in residential care for older people

The overall aim of the thesis was to investigate and explore job satisfaction, strain and stress of conscience (SC) among nurse assistants (NAs) working in residential care for older people. The thesis had a descriptive, cross-sectional and correlational design and consisted of one paper where qualitative methodology was used and three where quantitative methodology was used. The qualitative study

The added predictive value of biphasic events in ST analysis of the fetal electrocardiogram for intrapartumfetal monitoring

ObjectiveTo study the predictive value of biphasic ST-events for interventions for suspected fetal distress and adverse neonatal outcome, when using ST-analysis of the fetal electrocardiogram (FECG) for intrapartum fetal monitoring. DesignProspective cohort study. SettingThree academic hospitals in Sweden. PopulationWomen in labor with a high-risk singleton fetus in cephalic position beyond 36week

Recurrent Non-Muscle-Invasive Bladder Cancer

A characteristic feature of non-muscle-invasive bladder cancer (NMIBC) is the high risk of recurrent disease after primary treatment. Although only a minority of cases eventually progress to a life-threatening muscle-invasive tumour, it is necessary to conduct long-term follow-up with repeated cystoscopies. In addition to the negative mental and physical impact that this has on the patient, the ex

External or internal fixation in the treatment of non-reducible distal radial fractures? A 5-year follow-up of a randomized study involving 50 patients

Background and purpose We have previously shown in a randomized study that in the first year after treatment, open reduction and internal fixation resulted in better grip strength and forearm rotation than closed reduction and bridging external fixation. In the present study, we investigated whether this difference persists over time. Patients and methods The 50 patients included in the original s

Hierarchical scheduling and disturbance management in the process industry

The integration of scheduling and control in the process industry is a topic that has been frequently discussed during the recent years, but many challenges remain in order to obtain integrated solutions that may be implemented at large-scale industrial sites. This paper introduces a general framework for production scheduling (PS) and detailed production scheduling (DPS) using a two-level hierarc

Propagation pattern analysis during atrial fibrillation based on sparse modeling

Abstract in UndeterminedIn this study, sparse modeling is introduced for the estimation of propagation patterns in intracardiac atrial fibrillation (AF) signals. The estimation is based on the partial directed coherence function, derived from fitting a multivariate autoregressive model to the observed signal using least-squares (LS) estimation. The propagation pattern analysis incorporates prior i

The adhesive behavior of extracted latex polymers towards silicon oxide and cellulose

The objective with this work is to compare the adhesive behavior for latex polymers of different glass transition temperatures (T-g) at different length scales and with different contact times. This is accomplished by two techniques: AFM colloidal probe force measurements and JKR-measurements. The aim is to compare the results from these two techniques and relate them to the interaction of the lat

Generalization of the classical xyz-polarization analysis technique to out-of-plane and inelastic scattering

The technique of longitudinal ("xyz") polarization analysis has been used successfully for many years to study disordered magnetic materials in thermal and cold neutron diffraction experiments. The technique allows the simultaneous and unambiguous separation of the nuclear, magnetic, and nuclear spin-incoherent contributions to the scattering. The technical advances seen in recent years, such as t

A high pressure X-ray photoelectron spectroscopy study of oxidation and reduction of Rh(100) and Rh nanoparticles

We have studied the oxidation and reduction of Rh(100) and SiO2 supported Rh particles using high pressure X-ray photoelectron spectroscopy. We show that the formation and reduction of Rh bulk oxide can be followed in situ in O-2 and CO pressures in the range of 0.1 Torr. In general, the oxidation/reduction processes are similar on Rh(100) and the nanoparticles, but there are significant differenc

Entusiasm, skepsis, distans: studier i svensk-tyska förbindelser inom medicinen 1933–1945

The aim of this thesis is to describe and analyse Swedish-German contacts in medicine 1933-1945. It shows how the National Socialist German Physicians’ Federation (NSDÄB) tried to strengthen connections with the Swedish medical profession and academic medicine and to spread NS-propaganda to carefully selected Swedish physicians. The dissertation consists of four papers. In the first paper the inte

Quantum mechanical approach to probing the birth of attosecond pulses using a two-colour field

We investigate the generation of even and odd harmonics using an intense laser and a weak second harmonic field. Our theoretical approach is based on solving the saddle-point equations within the strong field approximation. The phase of the even harmonic oscillation as a function of the delay between the fundamental and second harmonic field is calculated and its variation with energy is found to
