Proton exchange membrane fuel cells (PEMFCs) are expected to play a significant role in the next generation of energy systems and road vehicles for transportation. To achieve high performance, low cost and high reliability, significant attention is needed on detailed modeling and simulation of various physical processes in PEMFC unit-cells. Substantial effort is also required to reach proper water

Reconstruction of movement control properties of the brain could result in many potential advantages for application in robotics. However, a hampering factor so far has been the lack of knowledge of the structure and function of brain circuitry in vivo during movement control. Much more detailed information has recently become available for the area of the cerebellum that controls arm-hand movemen

The V-BLAST system has been shown to be capable of exploiting the capacity advantage of multiple antenna systems. The square root algorithm for V-BLAST detection is attractive to hardware implementations due to low computational complexity and numerical stability. A low complexity VLSI architecture of the square root algorithm is presented in this paper. The proposed architecture is scalable for v

Background Ulcerative colitis is characterized by relapsing mucosal inflammation where the lesions include tissue-damaging granulocytes. In addition, T cells and natural killer (NK) cells play important pathophysiologic roles. Chemokines are a large family of peptides that play key roles in the regulation of inflammation. The CXC-chemokines, growth-related oncogene (GRO)-alpha/CXCL1 and interleuki

OBJECTIVE: We examined the prospective association between self-labeled and witness-reported bullying and the risk of newly onset of depression. METHODS: Employees were recruited from two cohorts of 3196 and 2002 employees, respectively. Participants received a questionnaire at baseline in 2006 to 2007 with follow-up in 2008 to 2009 and 2011. New cases of depression were diagnosed in the follow-

Objective. To explore experienced general practitioner (GP) tutor perceptions of a skilled GP tutor of medical students. Design. Interview study based on focus groups. Setting. Twenty GPs experienced in tutoring medical students at primary health care centres in two Swedish regions were interviewed. Method. Four focus-group interviews were analysed using qualitative content analysis. Subjects. Twe

Nuclear magnetic resonance spectroscopy and rheological analysis have been used to investigate the stability of mechanically induced tri-ethylene-glycol-mono-n-decyl-ether (C10E3)/deuterium oxide (D2O) multi-lamellar vesicles (MLVs) and the transition from MLVs to planar lamellae. It was found that MLVs prepared by vortex stirring, relax back to the lamellar phase in a few hours while the relaxati

Breast cancer is a heterogenous disease and it is of importance to select patients with regard to different prognosis and treatment sensitivity to individualize treatment regimes. In this study we successfully adapted a protein extraction protocol from mRNA extracted tumor samples enabling two-dimensional gel electrophoresis (2-DE) analysis of samples previously analyzed by cDNA microarray. The ai

Background: The relationship between atherothrombotic disease and venous thromboembolism (VTE) remains unclear. Patients and methods: In a cohort of 23 796 consecutive autopsies, performed using a standardized procedure and representing 84% of all in-hospital deaths between 1970 and 1982 in an urban Swedish population, we investigated the relationship between verified arterial thrombosis and VTE,

Academics have had numerous responsibilities during the centuries. However, now with global climate changes and the attendant, looming crises, it is increasingly crucial that administrators, faculty members, graduate, undergraduate students, staff members and alumni work together with governmental.. non-governmental and industrial members in envisioning, societies that are truly sustainable. The v

The aim of this study was to investigate patients’ experiences of living with peripheral arterial disease (PAD) and the influence on activities of daily living. Twenty-four patients with various degrees of PAD were interviewed. The transcribed texts were analysed using manifest and latent content analysis. Living with PAD meant carrying a hard-to-bear physical, social and emotional burden, and str

Photofragmentation of argon clusters of average size ranging from 10 up to 1000 atoms is studied using soft x-ray radiation below the 2p threshold and multicoincidence mass spectroscopy technique. For small clusters (N=10), ionization induces fast fragmentation with neutral emission imparting a large amount of energy. While the primary dissociation takes place on a picosecond time scale, the fragm

Background In January 2004, EMEA approved Y-90-radiolabelled ibritumomab tiuxetan, Zevalin, in Europe for the treatment of adult patients with rituximab-relapsed or -refractory CD20+ follicular B-cell non-Hodgkin's lymphoma. The number of European nuclear medicine departments using Zevalin is continuously increasing, since the therapy is often considered successful. The Therapy, Oncology and Dosim
