Almost all boreal and temperate forest tree species live in symbiosis with ectomycorrhizal fungi (EMF); the trees transfer carbon (C) to the fungi in exchange for nutrients and water. Several studies have shown that experimental application of inorganic nitrogen (N) represses production of EMF extramatrical mycelia (EMM), but studies along N deposition gradients are underrepresented. Other environ
Despite the fact that large welfare states are vulnerable to free-riding, the idea that universal welfare states lead to higher trust levels in the population has received some attention and support among political scientists recently. This paper argues that the opposite direction of causality is more plausible, i.e. that populations with higher trust levels are more prone to creating and successf
Uniform electroporation of the heterogeneous structure of spinach leaf cross section is a technological challenge that is addressed in this investigation. Three dimensional models were created with cells arranged in specific tissue types, considering a leaf with its air fraction and a leaf where the air fraction was replaced by a solution of known properties using vacuum impregnation. The models w
We have investigated the base-collector breakdown voltage of type I InGaAs/InP DHBTs, which is shown to be dominated by band-to-band tunneling in the base-collector grade. By optimizing the grade we obtain a 20% increase in the breakdown voltage compared with traditional grades.
Nanowire heterostructures define high-quality few-electron quantum dots for nanoelectronics, spintronics, and quantum information processing. We use a cooled scanning probe microscope (SPM) to image and control an InAs quantum dot in an InAs/InP nanowire using the tip as a movable gate. Images of dot conductance vs tip position at T=4.2 K show concentric rings as electrons are added, starting with
European white stork are long considered to diverge to eastern and western migration pools as a result of independent overwintering flyways. In relatively recent times, the western and northern distribution has been subject to dramatic population declines and country-specific extirpations. A number of independent reintroduction programs were started in the mid 1950s to bring storks back to histori
The public health impact of population-based mammography screening programs depends on high participation rates. Thus, monitoring participation rates, as well as understanding and considering the factors influencing attendance, is important. With the goal to acquire information on the appropriate level of intervention for increasing screening participation our study aimed to (1) examine whether, o
Background: Climate change affects human health in various ways. Health planners and policy makers are increasingly addressing potential health impacts of climate change. Ethiopia is vulnerable to these impacts. Assessing students' knowledge, understanding and perception about the health impact of climate change may promote educational endeavors to increase awareness of health impacts linked to cl
One of the most effective propane to acrylonitrile ammoxidation catalyst is comprised of the two phases M1 (orthorhombic) Mo7.5V1.5NbTeO29 and M2 (pseudo-hexagonal) Mo4V2Te2O20. Under reaction conditions, the two phases work in symbiosis with each other where M1 is the paraffin activating component and M2 is the olefin activating component. Since the catalytic improvement of either phase should re
Recent research has shown that there is a substantial skill difference in Sweden between natives and second-generation immigrants. The objective of this study is to find out whether there exists a relationship between immigrant school segregation and the individual's human capital. The variation in immigrant concentration rate between cohorts within a school generally does not affect the individua
The World Health Organization/United Nations Children's Fund Baby-Friendly Hospital Initiative: Revised, Updated, and Expanded for Integrated Care (2009) identifies the need for expanding the guidelines originally developed for maternity units to include neonatal intensive care. For this purpose, an expert group from the Nordic countries and Quebec, Canada, prepared a draft proposal, which was dis
Background: Chronic noninfectious, nonallergic rhinitis (NINAR) is a complex syndrome with a principally unknown pathophysiology. New technology has made it possible to examine differentially expressed genes and according to network theory, genes connected by their function that might have key roles in the disease. Methods: Connectivity analysis was used to identify NINAR key genes. mRNA was extra
Bog sites and wetland settlement during the Mesolithic: research from a bog in central Scania, southern Sweden The bogs Agerods Mosse and Ronneholms Mosse with their total area of 12 km(2), form a north-westerly arm of the Ringsjon Basin of central Scania, in the southernmost part of Sweden. In the 1940s and 1970s excavations of Early Mesolithic sites around and within the bog Agerods Mosse were c
The paper focuses on the location dynamics and spatial distribution of talent by workplace to provide evidence of the multiplicity of economic geographies of city regions. City regions are not just homogenous growth machines but complex urban landscapes. The economic growth and revitalisation of the city region and the rise of the knowledge economy, including the growth of advanced business servic
Purpose: The resulting plans from a new type of treatment planning system called SharePlan (TM) have been studied. This software allows for the conversion of treatment plans generated in a TomoTherapy system for helical delivery, into plans deliverable on C-arm linear accelerators (linacs), which is of particular interest for clinics with a single TomoTherapy unit. The purpose of this work was to
