Frostnedbrytning av betong kan få allvarliga konsekvenser för en konstruktions säkerhet, beständighet och funktionsduglighet eftersom betongens hållfasthet försämras. Frostskador uppstår vanligtvis i konstruktioner med hög fuktbelastning och som periodvis utsätts för frostangrepp. Olika typer av betongskador, vilka kan misstänkas vara frostrelaterade, har påträffats i svenska vattenkraftsanläggninFrost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. Different types of concrete damage, which are suspected to be frost related, have been observed in concrete structures in Swedish

Street lighting is an essential feature of pedestrian paths that may increase the amount of walking. This study aimed to identify associations between perceived lighting qualities, and experience of the lit environment and performance of critical tasks. In a full-scale laboratory 89 participants walked along a pedestrian path with three different outdoor lighting applications (CDM and LEDs). After

To facilitate the justification of an X-ray or nuclear medicine investigation and for informing patients, it is desirable that the individual patient's radiation dose and potential cancer risk can be prospectively assessed and documented. The current dose-reporting is based on effective dose, which ignores body size and does not reflect the strong dependence of risk on the age at exposure. Risk es

Background: TCF7L2 is a central transcription factor in the canonical wingless-type MMTV integration site (WNT) signaling pathway, and genetic variants in TCF7L2 have been found to interact with dietary fiber intake on type 2 diabetes risk. Here, we investigate whether other type 2 diabetes genes could be involved in the WNT signaling pathway and whether variants in such genes might interact with

Silicon photomultipliers (SiPMs) are an enabling solid-state technology for low light sensing, with single photon sensitivity and photon number resolving capability. They feature an extremely high internal gain at the 106 level, comparable to photomultiplier tubes (PMTs), with the advantage of low operating voltage (~50 V compared to ~1000 V for PMT) and low energy consumption. The solid-state tec

One mechanism of resistance of prostate cancer (PCa) to enzalutamide (MDV3100) treatment is the increased expression of AR variants lacking the ligand binding-domain, the best characterized of which is AR-V7. We have previously reported that Phosphatidylinositol-4-phosphate 5-kinase alpha (PIP5Kα), is a lipid kinase that links to CDK1 and AR pathways. The discovery of PIP5Kα inhibitor highlight th

Outdoor lighting makes public space accessible after dark and aims to improve the safety of pedestrians. A systematic literature review shows that facial recognition is the most relevant visual task for judging the potential threat of other pedestrians. In the identified literature it has been operationalized as the task of recognising gender; guessing identity or seeing facial features. However,

Vertical InAs nanowire transistors are fabricated on Si using a gate-last method, allowing for lithography-based control of the vertical gate length. The best devices combine good ON- and OFF-performance, exhibiting an ON-current of 0.14 mA/μm, and a sub-threshold swing of 90 mV/dec at 190 nm LG. The device with the highest transconductance shows a peak value of 1.6 mS/μm. From RF measurements, th

This thesis makes a contribution to network theory and how it applies to economics. It consists of three self-contained papers. It predominantly considers how connections between economic entities can affect economic outcomes. In particular, the first two papers examine social learning, in the one case by applying it to portfolio choice, and in the other by conducting an experiment to determine ho

Are capitalists more likely than others to justify ‘immoral’ acts such as bribery ortax evasion? This chapter investigates the conditions under which this is the case.While qualitative studies continue to document the nuances, mechanisms, andpractices of cheating and fraud among capitalists, quantitative work that tests the presence of fraud in modern economic life across a wide range of societies
