25 years of field exposure of pre-cracked concrete beams; combined impact of spacers and cracks on reinforcement corrosion

The state of corrosion of three pre-cracked concrete beams was investigated after 25 years of marine exposure (atmospheric, tidal and submerged). The influence of inadequate plastic spacers was found to overrule the possible impact of bending cracks on reinforcement corrosion. Increased chloride ingress was detected in cracked areas, but very little corrosion was observed where cracks reached the

Effect of mindfulness on physical activity in primary healthcare patients : a randomised controlled trial pilot study

Increased physical activity can have health benefits among inactive individuals. In Sweden, the healthcare system uses physical activity on prescription (PAP) to motivate patients to increase their physical activity level. Mindfulness may further heighten the internal motivation to engage in physical activity. However, previous research has not demonstrated clear evidence of such an association.AI

Obtaining archaeointensity data from British Neolithic pottery : A feasibility study

There is a significant lack of geomagnetic field strength (archaeointensity) measurements for many archaeological time periods in the United Kingdom (UK). This not only makes past geomagnetic secular variation difficult to model but also limits the development of archaeointensity dating. This paper presents the first archaeointensity study on UK Neolithic material. In this study, twenty-five sherd

Exploring uncertainties in global crop yield projections in a large ensemble of crop models and CMIP5 and CMIP6 climate scenarios

Concerns over climate change are motivated in large part because of their impact on human society. Assessing the effect of that uncertainty on specific potential impacts is demanding, since it requires a systematic survey over both climate and impacts models. We provide a comprehensive evaluation of uncertainty in projected crop yields for maize, spring and winter wheat, rice, and soybean, using a

Ageing and air leakage assessment of a nuclear reactor containment mock-up : VERCORS 2nd benchmark

Electricité de France (EDF) operates a large fleet of nuclear reactors and is responsible for demonstrating the safety of facilities, including concrete containment buildings (CCB), which are non-replaceable components. The leak-tightness of CCBs is assessed every 10 years during integrated leak-rate tests (IRLT). For double-wall containments, which have no metallic liners, the leak-tightness is s

The influence of soil structure on microbial processes in microfluidic models

The way microbes behave in nature can vary widely depending on the spatial characteristics of the habitats they are located in. The spatial structure of the microbial environment can determine whether and to which extent processes such as organic matter degradation, and synergistic or antagonistic microbial processes occur. Investigating how the different spatial characteristics of microhabitats i

Effects of hole configuration on film cooling effectiveness and particle deposition on curved surfaces in gas turbines

In this paper, effects of four different hole configurations on film cooling performance and particle deposition are investigated numerically on a curved surface. The RNG k-ε turbulence model is used, and the discrete phase model is developed by user-defined functions. The particle deposition on the curved surface is analyzed by calculated results of capture and impact efficiencies. Results show t

Parents' perception on cause of malaria and their malaria prevention experience among school-aged children in Kutcha district, Southern Ethiopia; qualitative study

Introduction School-aged children become a highly vulnerable group for malaria, yet they are less likely to use malaria prevention interventions. Previous studies exploring perception on cause of malaria mainly focused on pregnant mothers or parents of children under age five years. Exploring parent's perception on cause of malaria and their experiences on the prevention of malaria and associated

Response of a Li-glass/multi-anode photomultiplier detector to collimated thermal-neutron beams

The response of a position-sensitive Li-glass scintillator detector being developed for thermal-neutron detection with 6 mm position resolution has been investigated using collimated beams of thermal neutrons. The detector was moved perpendicularly through the neutron beams in 0.5 to 1.0 mm horizontal and vertical steps. Scintillation was detected in an 8 × 8 pixel multi-anode photomultiplier tube

Sero-prevalence of hepatitis B virus and associated factors among pregnant women in Gambella hospital, South Western Ethiopia : facility based cross-sectional study

BACKGROUND: Hepatitis B virus (HBV) is a hepatotropic deoxyribonucleic acid (DNA) virus which causes death. More than 300 million people have chronic liver infections globally and about 600,000 people die annually from acute or chronic complications of hepatitis B infection. Recent studies conducted in Ethiopia showed moderate endemicity (3-7.8%) of HBV among pregnant women. However, there is pauc

Rinkeby - en tunnelbanestation som alla andra : En utvärdering av samverkan vid lokalt brottsförebyggande arbete

Med anledning av oroligheter i Rinkeby tunnelbanestation har företrädare för Polisen, MTR Nordic, Rinkeby-Kista Stadsdelsförvaltning, FastPartner, Securitas, Säkerhet Ordningsbevakning SOB (SOB) och Trygghetscentralen (TC) arbetat utifrån Brå:s samverkansmodell för lokalt brottsförebyggande arbete.Denna utvärdering undersöker om samverkansmodellen varit framgångsrik, om de lokala brottsförebyggand

Administrating sickness: The workings of an all-female sickness fund, 1898–1931

This chapter investigates the characteristics of a successful voluntary sickness fund in early twentieth-century Sweden. The practices of the Seamstresses Sickness and Burial Fund reveal how a working-class organisation functioned in improving the living conditions of its members. When it was first founded in 1898, it was a small all-female and marginal sickness fund, but by the 1930s it had devel

Achieving the Circular Economy: Exploring the Role of Local Governments, Business and Citizens in an Urban Context

Urbanisation and climate change are urging cities to find novel pathways leading to a sustainable future. The urban context may be viewed as a new experimentation space to accelerate the transition to a circular economy. Urban symbiosis and circular economy are emerging concepts attracting more and more attention within the urban context. Moreover, new business models are emerging around sharing a

Resilience for Communication Faults in Reactive Power Sharing of Microgrids

In this paper, we consider the distributed reactive power sharing control problem for an autonomous inverterbased microgrid with resilience for communication faults, which may be caused by partial communication link failures or some channel manipulation attacks. Under the standard decoupling approximation for bus angle differences, the reactive power flow of each inverter can be controlled by mani

Car Sharing as a Strategy to Address GHG Emissions in the Transport System : Evaluation of Effects of Car Sharing in Amsterdam

Shared mobility options, such as car sharing, are often claimed to be more sustainable, although evidence at an individual or city level may contradict these claims. This study aims to improve understanding of the effects of car sharing on transport-related emissions at an individual and city level. This is done by quantifying the greenhouse gas (GHG) emissions of the travel habits of individuals
