A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. To reduce the costs of solar electricity, tiltable reflectors have been introduced in the construction to focus radiation onto the solar cells. The reflectors make it possible to contro
Objectives: To investigate the safety of a novel percutaneous circulatory support device during high-risk percutaneous coronary intervention (PCI). Background: The Reitan catheter pump (RCP) consists of a catheter-mounted pump-head with a foldable propeller and surrounding cage. Positioned in the descending aorta the pump creates a pressure gradient, reducing afterload and enhancing organ perfusio
OBJECTIVE-Many genetic variants have been associated with glucose homeostasis and type 2 diabetes in genome-wide association studies. Zinc is an essential micronutrient that is important for beta-cell function and glucose homeostasis. We tested the hypothesis that zinc intake could influence the glucose-raising effect of specific variants. RESEARCH DESIGN AND METHODS-We conducted a 14-cohort meta-
{Cis-1,3-bis[(di-tert-butylphosphino)methyl]cyclohexyl}palladium(II)trif luoroacetate (1) acts as a precatalyst for the Suzuki reaction of aryl halides with phenylboronic acid in the absence or presence of mercury to give the product in modest to reasonably good yields. The reaction was monitored by P-31- and H-1 NMR spectroscopy in a stepwise fashion, concluding that complex 1 reacts with activat
There are great regional variations in the use of plasma products. Evidence-based guidelines for plasma treatment are lacking. The Swedish market offers a non-commercial plasma product, produced by the hospital-based transfusion departments. There is also the commercial, virus-inactivated “SD plasma”. This is more expensive than the non-commercial plasma, yet it has not been shown to reduce the ri
Persson, B. (2011). Family and School Psychosocial Environment (FSPE): Development of a brief questionnaire measuring perceived psychosocial environments in children/siblings. Scandinavian Journal of Psychology. The aim of the study was to develop a short Swedish standardized, factor analyzed and cross-validated, family and school psychosocial environment questionnaire (FSPE). The study was based
Erythropoietin (EPO) and its covalently modified analogs are neuroprotective in various models of brain damage and disease. We investigated the effect on brain damage and memory performance, of a continuous 3-day intravenous infusion of EPO, starting 20 min after a transient 10 minute period of global cerebral ischemia in the rat.
The synthesis of pharmaceuticals and catalysts more and more relies on enantiopure chiral building blocks. These can be produced in an environmentally benign and efficient way via bioreduction of prochiral ketones catalyzed by dehydrogenases. A productive source of these biocatalysts is the yeast Saccharomyces cerevisiae, whose genome also encodes a reductase catalyzing the sequential reduction of
New roles for dogs and humansBased on the archaeological finds during the Neolithic we interpret the relationship between humans and their dogs to have significantly changed. People gained an increased understanding of the dog's different, unique properties. The dogs were stimulated by the work and collaboration, and probably developed mentally. Maybe, dogs specialized in different tasks?The dogs
OBJECTIVE: To build mathematical models to evaluate the individual risk of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm using clinical data, sonographic endometrial thickness and power Doppler ultrasound findings. METHODS: Of 729 consecutive patients with postmenopausal bleeding, 261 with sonographic endometrial thickness ≥ 4.5 mm and
The RF performance of vertical nanowire metal-oxide-semiconductor field-effect transistors in realistic layouts has been calculated. The parasitic capacitances have been evaluated using full 3-D finite-element method calculations, combined with self-consistent Schrodinger-Poisson calculations for the intrinsic gate capacitances. It is shown that a performance comparable to planar FETs can be achie
The notion of design research entails research where design practice forms part of the knowledge production. Based on our characterization of the nature of design, we propose to conceptualize this kind of research as programmatic design research. Two ongoing PhD projects in interaction design are presented as examples of programmatic research processes, highlighting issues to do with the virtues a
Laser-induced breakdown spectroscopy (LIBS) was used in this study to measure quantitatively the sodium (Na) and potassium (K) release from burning coal particles under oxy-fuel combustion environments. A specially designed laminar premixed burner was employed to provide a postflame environment with different O-2 and CO2 concentrations, in which the effects of O-2 and CO2 on the release of Na and
Popular Abstract in Swedish Cancer uppstår via genetiska förändringar som leder till ohämmad reglering av celltillväxt. Tumörer i mjukdelar utgör en grupp av solida tumörer, med över 100 histologiska typer. Mjukdelstumörer uppstår från mesenkymal vävnad, som inkluderar fett, bindväv, muskulatur, och det perifera nervsystemet. Mjukdelstumörer är en extremt heterogen grupp, både vad gäller morfologiThe focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas. The possible molecular targets for these aberrations were further studied t
We consider detection over intersymbol interference channels that are unknown at the receiver. For such a kind of systems, we consider an alternative approach to the design of a reduced-complexity receiver based on channel shortening without the explicit estimation of the channel impulse response. The proposed solution allows a simplification of the receiver architecture and a faster convergence f
Although advances in cardiopulmonary resuscitation have improved survival from cardiac arrest (CA), neurologic injury persists and impaired mitochondrial bioenergetics may be critical for targeted neuroresuscitation. The authors sought to determine if excellent cardiopulmonary resuscitation and postresuscitation care and good traditional survival rates result in persistently disordered cerebral mi
We present experimental measurements of the coherence of an undulator synchrotron radiation source near to the diffraction limit condition. These measurements have been done following two objectives. The first one is to verify a fundamental point of the theory of synchrotron radiation. To our knowledge, since it has been re-written by Geloni et al. [1], no experimental verification to validate the
