Radioactivity exploration from the Arctic to the Antarctic. Part 3. The SWEDARP expedition Oct 1988 – April 1989

The Swedish Antarctic Research Expedition named “SWEDARP” was performed during October 1988 through April 1989. The aim of our project was to study the radioactivity in air and water from Gothenburg to the Antarctic. Between Gothenburg and the Equator, the average activity concentration of 7Be in air was 4.3 ± 0.7 mBq/m3. The activity concentration of 7Be in the South Atlantic down to Antarctica v

Theoretical Developments for the Real-Time Description and Control of Nanoscale Systems

In the age of miniaturization where the physical systems approach the nanoscale limit andwhere more complex materials are created there is necessity for understanding in terms ofquantum mechanics. The understanding then opens and gives possibilities for manipulationand engineering of such systems and thus practical applications.Quantum mechanics states that the electron cannot be characterized as In this thesis we focus on improvements of the description of the electron-electron correlation effects in nonequilibrium nanosystems. We mainly focus on developments of two nonequilibrium methods, namely the formalism of Nonequilibrium Green’s Function and Time Dependent Density Functional Theory and we explore the possibility to improve existing approximations in these theories. A smaller part o

Investigations into the kinetics and thermodynamics of Sb(III) adsorption on goethite (α-FeOOH)

This study reports thermodynamic and kinetic data of Sb(III) adsorption from single metal solutions onto synthetic aqueous goethite (α-FeOOH). Batch equilibrium sorption experiments were carried out at 25 °C over a Sb:Fe molar range of 0.005-0.05 and using a goethite concentration of 0.44 g Fe/L. Experimental data were successfully modelled using Langmuir (R2 ≥ 0.891) and Freundlich (R2 ≥ 0.990) i

OBJECTIVESThe symposium will provide the know-how about powered mobility use in children with Spinal Muscular Atrophy Type I. Define what are the barriers of their mobility and how powered mobility can facilitate participation and social interaction. Disseminate the importance of family involvement in early powered mobility through the use of adapted motorized devices supporting development of fun

Phenotypic Refinement of Heart Failure in a National Biobank Facilitates Genetic Discovery

Heart failure (HF) is a morbid and heritable disorder for which the biological mechanisms are incompletely understood. We therefore examined genetic associations with HF in a large national biobank, and assessed whether refined phenotypic classification would facilitate genetic discovery. Methods: We defined all-cause HF among 488 010 participants from the UK Biobank and performed a genome-wide a

Organized Self-help Housing as a Method for achieving more Sustainable Human Settlements

There is a growing interest in organized self-help housing (OSHH) from both authoriti es and Non Governmental Organizati ons (NGOs) working in the housing sector due to the magnitude of housing problems in developing countries and the challenge of achieving sustainable humansett lements. This paper focuses on the experiences of two NGOs, FUPROVI in Costa Rica and SADEL in Sweden, in facilitati ng

Scheduling conflicts in the low-wage labor force: the case of Swedish and US women

By comparing the work-hours-related experiences of women in two countries that differ in their labor protections and their social-service provision—in other words, that differ in the extent to which neoliberalism holds sway—this manuscript sheds light on the implications of neoliberalism in terms of women’s working conditions.Specifically, we analyze the protections offered by each country that co

Anastomotic diameters and strictures following esophagectomy and total gastrectomy in 256 patients

The prevalence of anastomotic strictures in esophageal anastomoses provides us with limited information about the anastomotic healing process. This prospective study evaluates the exact esophageal anastomotic diameters in 256 patients who underwent esophagectomy and esophagogastrostomy without pyloroplasty (n = 107) or total gastrectomy and Roux reconstruction (n = 149). No perioperative chemoradi

Induced Polarisation (IP) laboratory measurements on E. coli sand mixtures

The aim of the MIRACHL project is the characterisation and monitoring of insituremediation of chlorinated hydrocarbon contamination using an interdisciplinary approach and geophysical methods, such as DCIP (direct current induced polarisation) to investigate the remediation process.To interpret these geophysical field IP data, lab investigations with different kinds of bacteria are necessary to as

Search for chargino-neutralino production using recursive jigsaw reconstruction in final states with two or three charged leptons in proton-proton collisions at s =13 TeV with the ATLAS detector

A search for electroweak production of supersymmetric particles is performed in two-lepton and three-lepton final states using recursive jigsaw reconstruction, a technique that assigns reconstructed objects to the most probable hemispheres of the decay trees, allowing one to construct tailored kinematic variables to separate the signal and background. The search uses data collected in 2015 and 201

The effect of ph and storage temperature on the stability of emulsions stabilized by rapeseed proteins

Rapeseed press cake (RPC), the by-product of rapeseed oil production, contains proteins with emulsifying properties, which can be used in food applications. Proteins from industrially produced RPC were extracted at pH 10.5 and precipitated at pH 3 (RPP3) and 6.5 (RPP6.5). Emulsions were formulated at three different pHs (pH 3, 4.5, and 6) with soy lecithin as control, and were stored for six month

Por4NT featured high solub

Interleukin-1 beta neutralization attenuates traumatic brain injury-induced microglia activation and neuronal changes in the globus pallidus

Traumatic brain injury (TBI) increases the risk of delayed neurodegenerative processes, including Parkinson’s disease (PD). Interleukin-1beta (IL-1β), a key pro-inflammatory cytokine, may promote secondary injury development after TBI. Conversely, neutralizing IL-1β was found to improve functional recovery following experimental TBI. However, the mechanisms underlying the behavioral improvements o

Experimentally determined and Monte Carlo-calculated energy dependence of NaCl pellets read by optically stimulated luminescence for photon beams in the energy range 30 keV to 1.25 MeV

Ordinary salt, NaCl, has many properties suitable for dosimetry and has been suggested for both retrospective and prospective optically stimulated luminescence (OSL) dosimetry. Lately, the focus has been on NaCl that is compressed into solid pellets, as this improves both its handling and dosimetric properties. In this project, the energy dependence of NaCl pellets produced in-house was investigat

Evidence for Mesoproterozoic collision, deep burial and rapid exhumation of garbenschiefer in the Namaqua Front, South Africa

Metamorphic provinces such as the ∼1 ​Ga Grenvillian, ∼400 ​Ma Caledonide and Triassic Qinling Provinces often contain rocks with high-pressure assemblages such as eclogites, which formed at mantle depths in subduction zones. These are evidence of the accretion of terranes by subduction of oceans and collision to form large tectonostratigraphic provinces. The Mesoproterozoic Namaqua-Natal Province

Effects from Time Dependence of Ice Nucleus Activity for Contrasting Cloud Types

The role of time-dependent freezing of ice nucleating particles (INPs) is evaluated with the “Aerosol–Cloud” (AC) model in 1) deep convection observed over Oklahoma during the Midlatitude Continental Convective Cloud Experiment (MC3E), 2) orographic clouds observed over North California during the Atmospheric Radiation Measurement (ARM) Cloud Aerosol Precipitation Experiment (ACAPEX), and 3) super

Constraining the eruption history of Rangitoto volcano, New Zealand, using palaeomagnetic data

New Zealand's largest city, Auckland, is situated within the basaltic Auckland Volcanic Field (AVF). Therefore, understanding the eruption history of the local volcanoes in the field is of great importance in order to assess future hazards that they may pose. Rangitoto is the youngest and largest volcano in the AVF, although the timing of the first eruption and the duration of the volcanic activit

Atrial Fibrillatory Rate Characterization Extracted from Implanted Cardiac Monitor Data

The aim of this study is to characterize atrial fibrillatory rate (AFR) extracted from a cohort of continuously monitored atrial fibrillation (AF) patients as function of episode duration and onset time. The f-wave signal used to compute the AFR was extracted from a single lead ECG strip of the AF episodes stored in an Implantable Cardiac Monitor (ICM) in a cohort of 99 patients. The f-wave signal
