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

Phenological stage of tundra vegetation controls bidirectional exchange of BVOCs in a climate change experiment on a subarctic heath

Traditionally, biogenic volatile organic compound (BVOC) emissions are often considered a unidirectional flux, from the ecosystem to the atmosphere, but recent studies clearly show the potential for bidirectional exchange. Here we aimed to investigate how warming and leaf litter addition affect the bidirectional exchange (flux) of BVOCs in a long‐term field experiment in the Subarctic. We also ass

The Just Savings Principle

This chapter situates John Rawls’ just savings principle in a discussion about how much a nation-state should save. The main question addressed is whether this principle is a vi­able alternative to the dominant utilitarian theory of optimal growth. Rawls certainly gives savings a different aim (i.e., to create and maintain just institutions) and introduces additional permissibility conditions on rThis chapter situates John Rawls’ just savings principle in a discussion about how much a nation-state should save.

Photon Mapping Superluminal Particles

One type of light source that remains largely unexplored in the field of light transport rendering is the light generated by superluminal particles, a phenomenon more commonly known as Cherenkov radiation. By re-purposing the Frank-Tamm equation for rendering, the energy output of these particles can be estimated and consequently mapped to photons, making it possible to visualize the brilliant blu

Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability

The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. This thesis presents the development of different

Plant foods, dietary fibre and risk of ischaemic heart disease in the European prospective investigation into cancer and nutrition (EPIC) cohort

BACKGROUND: Epidemiological evidence indicates that diets rich in plant foods are associated with a lower risk of ischaemic heart disease (IHD), but there is sparse information on fruit and vegetable subtypes and sources of dietary fibre. This study examined the associations of major plant foods, their subtypes and dietary fibre with risk of IHD in the European Prospective Investigation into Cance
