Utgravningene ved vestfronten av Nidaros domkirke : Del 1

This reports presents the results of an excavation conducted next to the west front of the cathedral in Trondheim. In all 11 phases of activity pre-dating the construction of the cathedral were recorded. The earliest features on the site are interpreted as representing part of a late 9th or 10th century farmstead. Thick deposits of soapstone chips are related to various phases of the buildning of

Promoting water-related innovation through networked acceleration : Insights from the Water Innovation Accelerator

The current state of the water and sanitation sector has put water­related innovations high on the global policy agenda. However, the systemic complexity that typically surrounds such contexts call for actionable knowledge of how to enable and orchestrate innovative solutions by connecting different players via organized networks. In this study we explore and analyse the Water Innovation AcceleratThe current state of the water and sanitation sector has put water-related innovations high on the global policy agenda.

Is role playing in Requirements Engineering Education increasing learning outcome?

Requirements Engineering has attracted a great deal of attention from researchers and practitioners in recent years. This increasing interest requires academia to provide students with a solid foundation in the subject matter. In Requirements Engineering Education (REE), it is important to cover three fundamental topics: traditional analysis and modeling skills, interviewing skills for requirement

Crystal Structure of an Ammonia-Permeable Aquaporin

Aquaporins of the TIP subfamily (Tonoplast Intrinsic Proteins) have been suggested to facilitate permeation of water and ammonia across the vacuolar membrane of plants, allowing the vacuole to efficiently sequester ammonium ions and counteract cytosolic fluctuations of ammonia. Here, we report the structure determined at 1.18 Å resolution from twinned crystals of Arabidopsis thaliana aquaporin AtT

Laser spectroscopy applied to environmental, ecological, food safety, and biomedical research

Laser spectroscopy provides many possibilities for multidisciplinary applications in environmental monitoring, in the ecological field, for food safety investigations, and in biomedicine. The paper gives several examples of the power of multi-disciplinary applications of laser spectroscopy as pursued in our research group. The studies utilize mostly similar and widely applicable spectroscopic appr

Space charge limited current mechanism in Bi2S3 nanowires

We report on the charge transport properties of individual Bi2S3 nanowires grown within the pores of anodized aluminum oxide templates. The mean pore diameter was 80 nm. Space charge limited current is the dominating conduction mechanism at temperatures below 160 K. Characteristic parameters of nanowires, such as trap concentration and trap characteristic energy, were estimated from current-voltag

Is the subarctic landscape still a carbon sink? Evidence from a detailed catchment balance

Climate warming raises the question whether high-latitude landscape still function as net carbon (C) sinks. By compiling an integrated C balance for an intensely studied subarctic catchment, we show that this catchment's C balance is not likely to be a strong current sink of C, a commonly held assumption. In fact, it is more plausible (71% probability) that the studied catchment functions as a C s

Ion beam evaluation of silicon carbide membrane structures intended for particle detectors

Thin ion transmission detectors can be used as a part of a telescope detector for mass and energy identification but also as a pre-cell detector in a microbeam system for studies of biological effects from single ion hits on individual living cells. We investigated a structure of graphene on silicon carbide (SiC) with the purpose to explore a thin transmission detector with a very low noise level

Distribution of the secretory leucocyte proteinase inhibitor in human articular cartilage

The secretory leucocyte protease inhibitor, SLPI, is a low molecular weight inhibitor of proteases such as elastase and cathepsin G, which are released from leucocytes during phagocytosis. The purpose of this study was to show whether or not SLPI is produced in articular chondrocytes. In articular disorders, the protease-antiprotease balance is disturbed. For this reason it would be interesting to

Impaired phagocytosis and reactive oxygen species production in phagocytes is associated with systemic vasculitis

BACKGROUND: Anti-neutrophil cytoplasmic antibodies associated vasculitides (AAV) is a group of autoimmune diseases, characterized by small vessel inflammation. Phagocytes such as neutrophils and monocytes are the main effector cells found around the inflamed vessel wall. Therefore, we wanted to investigate aspects of function and activation of these cells in patients with AAV.METHODS: Flow cytomet

KIF5C S176 phosphorylation regulates microtubule binding and transport efficiency in mammalian neurons

Increased phosphorylation of the KIF5 anterograde motor is associated with impaired axonal transport and neurodegeneration, but paradoxically also with normal transport, though the details are not fully defined. JNK phosphorylates KIF5C on S176 in the motor domain; a site that we show is phosphorylated in brain. Microtubule pelleting assays demonstrate that phosphomimetic KIF5C (1-560)S176D associ
