Efficient evaluation of specific absorption rate (SAR) for MIMO terminals

Multi-antenna enabled terminal devices are required to comply with the standards for limiting human exposure to electric fields. However, when compared to traditional single-antenna terminals, a comprehensive evaluation of specific absorption rate (SAR) for multi-antenna terminals is impractical. This is because both the power allocation and phase of the electric fields from different antennas are

The housing environment of people with severe mental illness

Popular Abstract in Swedish Bostäder med särskild service som upplevs ge möjlighet till socialt umgänge, avskildhet och återhämtning har positiva effekter på livskvaliteten hos människor med psykisk funktionsnedsättning. Vidare visar resultaten från denna avhandling att den visuella upplevelsen av miljön och upplevelsen av hemlikhet är betydelsefulla för att etablera en stödjande atmosfär. BoendemSupported housing facilities (SHF) are among the most common housing solutions for people with severe mental illness (SMI). A poor level of physical-environment qualities and the re-creation of institutional atmospheres in these settings have been found in recent studies. The research focus in the psychiatric field has, however, largely neglected these topics and the available knowledge does not p

Hsp104 antagonizes alpha-synuclein aggregation and reduces dopaminergic degeneration in a rat model of Parkinson disease.

Parkinson disease (PD) is characterized by dopaminergic neurodegeneration and intracellular inclusions of alpha-synuclein amyloid fibers, which are stable and difficult to dissolve. Whether inclusions are neuroprotective or pathological remains controversial, because prefibrillar oligomers may be more toxic than amyloid inclusions. Thus, whether therapies should target inclusions, preamyloid oligo

An overview of some recent physical bounds in scattering and antenna theory

The objective of this paper is to give an overview of some recently developed sum rules and physical bounds in scattering and antenna theory. The sum rules are based on integral identities for Herglotz functions that relate the quantity of interest with its low and high-frequency behavior. The sum rules are transformed to bounds by estimating the integrals and applying variational results to the p

The importance of a common method and correct calculation of thermal bridges

This paper elucidates the increased need of correct calculations of thermal bridges for low/near zero energy buildings. The variability of the results from calculations of transmission losses for a building can be large if the calculation method within EN ISO 13789:2007 is not fully understood. A survey has been carried out which shows that there are no consensus in Sweden regarding how to define

The Role of Thermohaline Mixing in Intermediate- and Low-Metallicity Globular Clusters

It is now widely accepted that globular cluster red giant branch (RGB) stars owe their strange abundance patterns to a combination of pollution from progenitor stars and in situ extra mixing. In this hybrid theory a first generation of stars imprints abundance patterns into the gas from which a second generation forms. The hybrid theory suggests that extra mixing is operating in both populations a

Mn-silicide nanostructures aligned on massively parallel silicon nano-ribbons

The growth of Mn nanostructures on a 1D grating of silicon nano-ribbons is investigated at atomic scale by means of scanning tunneling microscopy, low energy electron diffraction and core level photoelectron spectroscopy. The grating of silicon nano-ribbons represents an atomic scale template that can be used in a surface-driven route to control the combination of Si with Mn in the development of

Lecidea variegatula – ny för Norden

I lavbulletinen 2014:2 skrev Ulf om en skånsk hotspot för stenlavar och rapporterade också om en obestämd Lecidea. Den har nu blivit bestämd till L. variegatula och det visade sig att det var en ny art för Norden. Här beskrivs den kortfattat än en gång.

The Gaia-ESO Survey: Kinematics of seven Galactic globular clusters

The Gaia-ESO survey is a large public spectroscopic survey aimed at investigating the origin and formation history of our Galaxy by collecting spectroscopy of representative samples (about 105 Milky Way stars) of all Galactic stellar populations, in the field and in clusters. The survey uses globular clusters as intra-and inter-survey calibrators, deriving stellar atmospheric parameters and abunda

Direct electrochemistry and Os-polymer-mediated bioelectrocatalysis of NADH oxidation by Escherichia coil flavohemoglobin at graphite electrodes

Escherichia coli flavohemoglobin (HMP), which contains one heme and one FAD as prosthetic groups and is capable of reducing O-2 by its heme at the expense of NADH oxidized at its FAD site, was electrochemically studied at graphite (Gr) electrodes. Two signals were observed in voltammograms of HMP adsorbed on Gr, at -477 and -171 mV vs. Ag vertical bar AgCl, at pH 7.4, correlating with electrochemi

Plant species from mesotrophic wetlands cause relatively high methane emissions from peat soil

Plants can influence methane emissions from wetland ecosystems by altering its production, consumption and transport in the soil. The aim of this study was to investigate how eight vascular plant species from mesotrophic to eutrophic wetlands vary in their influence on CH4 emissions from peat cores, under low and high N supply. Additionally, we measured the production of low-molecular-weight organ

Ventilation in situ after cardiac death improves pulmonary grafts exposed to 2 hours of warm ischemia

Background. The pulmonary donor pool would increase substantially if lungs could be donated after cardiac death (DCD). There have been ethical and legal obstacles since administration of heparin and cooling has to be done immediately after cardiac death. This study examines whether ventilation of DCD lungs without administering heparin or cooling the lungs after cardiac death could improve graft f

Mutual coupling reduction of two PIFAs with a T-shape slot impedance transformer for MIMO mobile terminals

Abstract in UndeterminedAn efficient technique is introduced to reduce mutual coupling between two closely spaced PIFAs for MIMO mobile terminals. The proposed mutual coupling reduction method is based on a T-shape slot impedance transformer and can be applied to both single-band and dual-band PIFAs. For the proposed single-band dual PIFAs, the 10 dB impedance bandwidth covers the 2.4 GHz WLAN ban

Swedish lung cancer radiation study group: the prognostic value of anaemia, thrombocytosis and leukocytosis at time of diagnosis in patients with non-small cell lung cancer

There is a need to improve the prognostic and predictive indicators in non-small cell lung cancer (NSCLC). At present, the main focus is on genetic predictive markers while the prognostic value of the standard blood variables related to haematopoiesis has been subjected to relatively limited attention. To study the prognostic potential of haemoglobin (Hgb), platelet (Plt) and white blood cell (WBC

Computations of the Flow around a Wind Turbine: Grid Sensitivity Study and the Influence of Inlet Conditions

The flow around a complete model wind turbine is computed using LES and the immersed boundary method. The influence of inlet velocity profile and turbulence level is evaluated. The inlet velocity profile was found to have major influence in the upper regions of the flow field. The imposed turbulence level had no major influence on the turbulent spectra but it's effect is clearly seen on the genera

Characterization of shear and compaction bands in a porous sandstone deformed under triaxial compression

The study of localized deformation in porous sandstones at the laboratory scale can yield valuable insights into the internal structures and mechanisms of shear zones and compaction bands that might impact on flow at a reservoir scale. Herein, we report results of a laboratory study of shear and compaction band formation in a porous sandstone using a range of full-field experimental techniques: ac
