Porphyrinoids are a family of molecules, which consist of large ring structures or macrocycles. One of the oldest, and most important, of the porphyrinoids is the biological molecule called porphyrin. Since the dawn of life, porphyrins have orchestrated photosynthesis and oxygen respiration, two of the most important energy-generating processes in nature. In addition to porphyrins, other porphyrinoids ...

Coherence properties of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal-to-noise ratio, axial resolution, and penetration depth of the system. In the present paper, we report the investigation of longitudinal spatial coherence properties of a pseudothermal light source (PTS) as a function of the laser spot size at the rotating diffuser ...

As the challenges associated with sustainability, urbanization, life quality and demography become more imminent, companies are adapting to the changing requirements by means of revised strategic approaches. Thus, enterprises are increasingly deviating from the traditionally absolute priority of maximizing total return for shareholders. While this priority is still important, businesses are also ...

Collecting objective physical activity data from research participants are increasingly done using consumer-based activity trackers. Several validation studies of Polar devices are conducted to date, but no systematic review of the current level of accuracy for these devices exist. The aim of this study is therefore to investigate the accuracy of current wrist-worn Polar devices that equips a triaxial ...

Increased geographical mobility, improved medical treatment, and prolonged life expectancy have changed the way of life for older persons and their next of kin. This chapter discusses intergenerational care, mainly from the next of kin’s point of view, when an older family member and the next of kin live far from each other. The study is based on my—the author’s—autoethnographic account of the ...

I denne oppgaven vil jeg presentere utviklingsprosessen av og mulighetene for et nytt redskap for kyst- og fjordflåten, dypvannsrunddorg. Dypvannsrunddorgen som redskap er basert på den tradisjonelle runddorgen. Forskjellen er at med en dypvannsrunddorg kan en styre dybden fritt og dermed ha bedre tilgang til fisk som står dypt. Systemet muliggjør også at en kan benytte større bruk sammenlignet med ...

<i>Background</i>- It remains uncertain whether activation of the complement system, assessed by the soluble terminal C5b‐9 complement complex (plasma TCC), is associated with future risk of incident venous thromboembolism (VTE).<p> <p><i>Objectives</i>- To investigate the association between plasma levels of TCC and future risk of incident VTE in a nested case‐control study, and to explore ...

<i>Background</i>: Knowledge about the treatment of skin and soft tissue infections in injecting drug users in countries with a low prevalence of antibiotic resistance is limited. We investigated bacterial antibiotic resistance and treatment of skin and soft tissue infections in Norwegian drug users.<p> <p><i>Methods</i>: We performed a two year clinical cross-sectional observational study in a ...

<i>Background</i> - The discovery of thermostable DNA polymerases such as Taq DNA polymerase revolutionized amplification of DNA by polymerase chain reaction methods that rely on thermal cycling for strand separation. These methods are widely used in the laboratory for medical research, clinical diagnostics, criminal forensics and general molecular biology research. Today there is a growing demand ...

Atomically thin, two-dimensional (2D) indium selenide (InSe) has attracted considerable attention because of the dependence of its bandgap on sample thickness, making it suitable for small-scale optoelectronic device applications. In this work, by the use of Raman spectroscopy with three different laser wavelengths, including 488, 532, and 633 nm, representing resonant, near-resonant, and conventional ...
