    Projektörer kan minska risken för arbetsskador2012In: VVS-Forum, ISSN 0346-4644, no 3, 72-73 p.Article in journal (Other (popular science, discussion, etc.))
    Abstract [sv]

    Ungefär en fjärdedel av alla arbetsplatsolyckor med dödlig utgång sker på byggarbetsplatser. Antalet anmälda arbetsskador per sysselsatt är cirka 50 procent högre i byggbranschen än genomsnittet i Sverige. Vanligast är belastningsskador, både akuta och på grund av långvarig belastning. Arbetsgivaren ansvarar för att arbetstagarna ska kunna utföra sina arbetsuppgifter utan att bli skadade eller sjuka. Men förutsättningarna för entreprenörernas skadeförebyggande arbete är olika i olika projekt. De beror bland annat på:- typ av projekt: ROT eller nybyggnation- tidsramar- ekonomiska ramar- byggnadens design: form, konstruktioner,byggprodukter- säkerhetsinformationen från projektering till produktion.

    Abstract [en]

    Företagshälsovård, fhv, är en viktig aktör i välfärdssamhället. Den ska bidra både till att förebygga ohälsa och främja hälsa samt till att ska pagoda och säkra arbetsplatser där de anställda inte riskerar att skadas eller bli sjuka. Omvärldens förväntningar är höga. För att uppfylla dem krävs att fhv har en bred kompetens och att arbetet bygger på samarbete både mellan olika kompetenser inom den egna verksamheten och med de företag och organisationer som fhv arbetar för.

    Abstract [en]

    Verksamhet, ekonomiska förutsättningar, drivkrafter och värderingar varierar för FHV:s kunder. För att lyckas i arbetet med att stödja kunden, behöver FHV förstå hur dessa faktorer påverkar arbetsmiljöarbetet och hur insatser bäst anpassas till varje kund.

    Abstract [en]

    Många företag med mindre än 50 anställda har någon form av avtal med FHV och de flesta är nöjda. Deras anställda står dock bara för en liten andel av alla arbetstagare som har tillgång till fhv. En stor del av småföretagen utnyttjar inte FHV:s breda kompetens utan anlitar dem främst för hälsoundersökningar. Det betyder att det finns en stor utvecklingspotential om man kan få de mindre företagen att efterfråga fler tjänster.

    Wire electronics and woven logic, as a potential technology for neuroelectronic implantsManuscript (Other (popular science, discussion, etc.))
    Abstract [en]

    New strategies to improve neuron coupling to neuroelectronic implants are needed. In particular, to maintain functional coupling between implant and neurons, foreign body response like encapsulation must me minimized. Apart from modifying materials to mitigate encapsulation it has been shown that with extremely thin structures, encapsulation will be less pronounced. We here utilize wire electrochemical transistors (WECTs) using conducting polymer coated fibers. Monofilaments down to 10 μm can be successfully coated and weaved into complex networks with built in logic functions, so called textile logic. Such systems can control signal patterns at a large number of electrode terminals from a few addressing fibres. Not only is fibre size in the range where less encapsulation is expected but textiles are known to make successful implants because of their soft and flexible mechanical properties. Further, textile fabrication provides versatility and even three dimensional networks are possible. Three possible architectures for neuroelectronic systems are discussed. WECTs are sensitive to dehydration and materials for better durability or improved encapsulation is needed for stable performance in biological environments.

    Biocompatibility of PEDOT/biomolecular composites intended for neural communication electrodesManuscript (Other (popular science, discussion, etc.))
    Abstract [en]

    Electrodes of the conjugated polymer poly(3,4-ethylene dioxythiophene) (PEDOT) have been shown to possess very attractive electrochemical properties for functional electrical stimulation (FES) or recording in the nervous system. Biomolecules already present in nervous tissue, added as counter ions in PEDOT electropolymerisation, could be a route to further improve the biomaterial properties of PEDOT, eliminating the need of surfactant counter ions like docedyl benzene sulphonate (DBS) or polystyrene sulphonate (PSS) in the polymerisation process. Such PEDOT/biomolecular composites using heparin, or hyaluronic acid, have been electrochemically investigated in a previous study and have been shown to retain the attractive electrochemical properties already proven for PEDOT:PSS.

     

    The aim of the present study is to evaluate biocompatibility of these PEDOT/biomolecular composites in vitro and also evaluate PEDOT:heparin biocompatibility in cortical tissue in vivo. Hereby, we also aim to identify a suitable test protocol, that can be used in future evaluations when further material developments are made.

     

    Material toxicity was first tested on cell lines, both through a standardised agarose overlay assay on L929 fibroblasts, and through elution tests on human neuroblastoma SH-SY5Y cells. Subsequently, a biocompatibility in vivo test was performed using PEDOT:heparin coated platinum probes implanted in the cerebral cortex of Sprague-Dawley rats. Tissue was collected at three weeks and six weeks of implantation and evaluated by immunohistochemistry.

     

    No cytotoxic response was seen to any of the PEDOT:biomolecular composites tested here. Furthermore, elution tests were found to be a practical and effective way of screening materials for toxicity and had a clear advantage over the agarose overlay assay, which was difficult to apply on other cell types than fibroblasts. Elution tests would therefore be recommendable as a screening method, at all stages of material development. In the in vivo tests, the stiffness of the platinum substrate was a significant problem, and extensive glial scarring was seen in most cases irrespective of implant material. However, quantification of immunological response through distance measurements from implant site to closest neuron, and counting of macrophage densities in proximity to polymer surface, was comparable to those of platinum controls. These results indicate that PEDOT:heparin surfaces were as compatible with cortical tissue as pure platinum controls.

    A system to quantify and visualize ventricular rotation pattern of the heart2009Patent (Other (popular science, discussion, etc.))
    Abstract [en]

    Different modalities have been used to describe the rotational motion of the ventricles of the heart and studies have indicated LV twist to be an additional integral component in LV function. So far, only amplitudes and timings of rotation have been reported, whereas no method is available to fully describe the rotation pattern of the ventricles. The object of the present application is to achieve a system that presents a novel way to quantify and visualize the ventricular rotation pattern of the heart. We present a novel method that assesses and describes the rotation pattern by calculating the rotation axis of the ventricle. Non- invasive image acquisition is required to collect rotation values from different positions of the myocardium. Thereafter, a kinematic model of a ventricle is constructed to determine the rotation planes at different levels of the heart. The motion of the rotation planes are visualized by plotting the normal vectors of the planes over time, i.e. the rotation axis of the planes. This new method is different to all other methods used today for assessing cardiac function, as it does not describe the amplitude of a motion but the relationship in motion between different parts within a ventricle. Preliminary results indicate that the rotation axis is more sensitive to changes in the rotation pattern than conventional measurements of ventricular rotation. This new method could be used for early detection of cardiac diseases and for selection of patients for and optimization of cardiac resynchronization therapy.

    Global and local detection of blood vessel elasticity2006Patent (Other (popular science, discussion, etc.))
    Abstract [en]

    The present invention is a non-invasive analysis system for detection of global and local blood vessel elasticity. The analysis system comprises two subsystems where subsystem 1 is data collecting unit and subsystem 2 is an analysis unit. The data collecting unit comprises one or many non-invasive image generating systems, or the data collecting system makes the registration possible of movement parameters that quantifies the dynamics of the blood vessel wall in longitudinal and radial directions. Subsystem 2 performs Wave Intensity Analysis which is an analysis method using co-related parts of the circulation system by measuring the intensity change (dl) of the blood vessel during a heart cycle. The intensity change is calculated as the product of the pressure derivate and the flow velocity derivate. In subsystem 2 the changes of pressure and flow are approximated by the deformation velocity or velocity of the radial and longitudinal direction, respectively. By calculating time constants and amplitudes of the intensity change graph a measure is obtained of the local and global elasticity of the blood vessel and atherosclerotic constrictions of arterial vessels may then be identified at an early stage.

    Abstract [sv]

    Artikelförfattaren,  konstaterar i detta inlägg att VVS-branschen inte verkar ha insett betydelsen av nya PBL (plan- och bygglagstiftningen). Han pekar också på att remissen om förändringarna i Boverkets byggregler (BBR) kan behöva göras om. Vidare föreslår han att ett VVS-säkerhetsverk inrättas för att stärka branschens positioner inom byggprocessen och att de kommunala VVS-inspektörernas roll förstärks.†Artikelförfattaren anser att många av de föreslagna kraven i nya BBR är luddiga och i många fall saknas krav helt.

    Abstract [en]

    Arrangement for the production of instantaneous or non-instantaneous multi-band images, to be transformed into multi- or hyperspectral images, comprising light collecting means, an image sensor array, and an instantaneous colour separating means, positioned before the image sensor array, and uniform spectral filters, for restricting imaging to certain parts of the electromagnetic spectrum. A filter unit is positioned before the colour separating means in the optical path in, or close to, converged light. Each filter mosaic consists of a multitude of homogeneous filtering regions. The transmission curves of the filtering regions of a colour or spectral filter mosaic can be partly overlapping, in addition to overlap between these transmission curves and those belonging to the filtering regions of the colour separating means.; The transmission curves of the colour or spectral filter mosaics and the colour separating means are suitably spread out in the intervals of a spectrum to be studied.

    The rotation axis of the left ventricle - A new concept derived from ultrasound data in healthy individualsManuscript (preprint) (Other (popular science, discussion, etc.))
    Abstract [en]

    Different modalities have been used to describe the circumferential motion of the left ventricle (LV) and studies have indicated LV twist to be an additional integral component in LV function. So far, only amplitudes of rotation have been reported, whereas the rotation pattern of the LV has not been fully described. However, data from a previous study on regional rotation have indicated that the axis around which the LV rotates, is not congruent to the longitudinal axis of the LV. The aim of the present study was to develop an ultrasound-based method to calculate the rotation axis of the LV in a three-dimensional aspect throughout the cardiac cycle and to apply it in a group of healthy individuals. An algorithm for calculation of rotation axes at the basal, mid-, apical and transitional levels of the LV was developed. By constructing a simplified model of the LV, based on rotation amplitudes measured at the basal, mid- and apical levels, rotation planes with similar values of rotation could be calculated at each level. The transition plane was defined as where the rotation values shifted from positive to negative. An overview of the rotation pattern was achieved by displaying data on deflection (angle between the rotation axis and the longitudinal axis of the LV) and direction (defined as the angle in a short-axis view of the LV with zero degrees at the lateral wall and increasing angles counterclockwise) of the rotation axes throughout the cardiac cycle. The deflection differed significantly from zero in all tested time points, i.e. the rotation axis was not congruent to the longitudinal axis of the LV. Rayleigh’s test for uniformity demonstrated a significant mean direction for each of the axes for the majority of the tested time points. Thus, the axis of rotation at different levels of the LV displayed a physiological pattern, where also stability of rotation could be assessed. Furthermore, the angle and level of the transition plane could be described over time. This new way of assessing rotational function provides further insight into the complexity of LV mechanics. The method has acceptable reproducibility but the potential clinical use of this method needs to be validated in further studies.
