    Curcumin and Fish Oil: Potential Alternative or Adjunctive Treatments to NSAIDs and Immune Modulating Medications for the Treatment of Chronic Inflammation

    The aim of the present review is to evaluate the efficacy and safety of curcumin and fish oil as alternative or adjuvant treatments to NSAIDs and immune modulating medications for the treatment of chronic inflammation. An online search of CINAHL, PubMed, Cochrane and Alt Healthwatchdatabases was conducted. It was limited to peer-reviewed articles and clinical trials in academic journals within the last ten years. Current research suggests that curcumin may be efficacious in the treatment of chronic inflammation. It is generally regarded as safe up to 12 gm/day with mild gastrointestinal effects but poor bioavailability has limited its clinical application. Current research provides evidence that fish oil is efficacious for the treatment of chronic inflammation in a variety of chronic diseases. It is generally regarded as safe at doses of 3 gm/day with mild gastrointestinal effects and no increased risk of bleeding. In vitro studies have demonstrated a synergistic anti-inflammatory effect when curcumin and fish oil are used concomitantly.https://commons.und.edu/pas-grad-posters/1030/thumbnail.jp

    Detection of CO2 in N2 and H2O using photoacoustics

    Photoacoustic spectroscopy is a technique where absorbed modulated light is released as heat, causing thermal expansion which can be detected using an acoustic transducer. It can be used to determine the absorption spectra or the concentration of a material. In this project, photoacoustic spectroscopy is performed on CO2 in N2 gas and on CO2 dissolved in water in the 2003 - 2006 nm range. Studies on CO2 concentrations can be used in environmental research and fish industries, to mention some applications. Linearity in the signal is demonstrated for concentrations over several orders of magnitude for the gas mixture. The effect of water vapour in the sample is investigated, and the optimal modulation frequency and other relevant factors are determined. For the water sample, different measurement cell configurations are investigated before achieving a photoacoustic signal. With the final configuration used, high concentrations of CO2 in water can be detected indirectly through a small layer of inert gas above the water. Smaller concentrations can not be detected due to a high noise level. Together with instruments for generating and modulating laser light and for detecting the acoustic signal, a gas sample measurement cell and a water sample measurement cell form the experimental setup. LabVIEW from National Instruments is used to develop a software for instrument control, data acquisition and data analysis.Master i FysikkMAMN-PHYSPHYS39

    Beyond Budgeting og eierskap : en kvalitativ studie av hvordan et moderne styringssystem skaper eierskap til strategiske mÄl

    Get PDF
    Budsjettet har tradisjonelt sett fremstÄtt som det fremste verktÞyet for virksomhetsstyring. I senere tid har andre og mer moderne styringssystemer vokst frem, deriblant styringsfilosofien Beyond Budgeting. Beyond Budgeting handler om Ä ta bort budsjettene fra virksomhetsstyringen, og i stedet implementere andre styringsverktÞy med Þkt fleksibilitet og dynamikk. Rapporten er en kvalitativ studie som tar sikte pÄ Ä besvare fÞlgende problemstilling: Hvordan skaper et moderne styringssystem eierskap til de strategiske mÄlene? Hovedfunnene i rapporten er at eierskapet ikke knyttes direkte mot strategiske mÄl, men heller indirekte via konkrete aksjoner. Mellomleder spiller en viktig rolle i oversettelsen av strategi til handling, og det moderne styringssystemet tilrettelegger for styring uten budsjetter. Psykologisk eierskap er forbundet med positive holdnings- og atferdseffekter, og et moderne styringssystem bÞr derfor fokusere pÄ Ä tilrettelegge for organisatorisk sammenstilling gjennom eierskap fremfor «top-down» implementering av rigide budsjettmÄl

    Temperature induced color change in gold nanoparticle arrays: Investigating the annealing effect on the localized surface plasmon resonance

    The localized surface plasmon resonance (LSPR) effect in metal nanoparticles is important for a range of applications, including photovoltaics and sensors. The actual LSPR effect is difficult to predict, because it can vary strongly with the size, shape, surface structure, and surrounding media of the nanoparticles. In order to understand this better, more experimental data are needed. Here, the authors present a study of the LSPR effect in macroscopic two-dimensional square arrays of gold nanoparticles, 50–80 nm in diameter with a pitch of approximately 160 nm, fabricated on borosilicate substrates. The arrays were exposed to different annealing temperatures in steps of 50 up to 600 °C. The authors observe an irreversible blue-shift of the LSPR extinction peak, from around 580 to around 520 nm at annealing temperatures of only 450 °C, an effect clearly visible to the naked eye. The authors also present measurements of the shape of the nanoparticles at the different annealing steps. These measurements were obtained using a combination of scanning electron microscopy (SEM) and atomic force microscopy (AFM). A carefully indexed pattern allowed us to measure the exact same nanoparticles with separate AFM and SEM instruments. The only clear effect that can be observed is that the nanoparticles appear to get smoother with annealing. Our results demonstrate that seemingly minor changes in the metal nanoparticle appearance can lead to a strong change in the LSPR effect. Our results also open up for potential applications in temperature sensing. The fact that the effect of temperature exposure can be observed with the naked eye without any need of electronic readout or power supply is particularly advantageous.publishedVersio

    Methods to Account for Design for Disassembly: Status of the Building Sector

    Get PDF
    Embracing the design for disassembly (DfD) mindset when constructing new and renovating existing buildings is a promising means of achieving our climate targets and putting the circular economy principles in practice, as promoted in the European Green Deal. Current greenhouse gas emissions’ accounting frameworks only deal with DfD to a certain extent. A better and more common understanding of how this can be carried out will not only help promote DfD but also shed light on how DfD should be seen in the context of other emission reduction measures. This could help to achieve balanced and credible scenarios that can be used in policy-making processes. When building components or materials are used over several cycles (buildings), the allocation of environmental impacts across the different buildings must be discussed. In an attempt to address this issue, this study examined whether and how current LCA standards for construction products and buildings consider such allocation issues.publishedVersio
