High-kinetic-energy photoemission spectroscopy of Ni at 1s: 6-eV satellite at 4 eV

Electron correlations are responsible for many profound phenomena in solid-state physics. A classical example is the 6-eV satellite in the photoelectron spectrum of Ni. Until now the satellite structure has only been investigated at the L shell and more shallow levels. Here we report a high-kinetic-energy photoemission spectroscopy (HIKE) investigation of Ni metal. We present 1s and 2p photoelectr

Identification of proteins involved in neural progenitor cell targeting of gliomas

Background: Glioblastoma are highly aggressive tumors with an average survival time of 12 months with currently available treatment. We have previously shown that specific embryonic neural progenitor cells (NPC) have the potential to target glioma growth in the CNS of rats. The neural progenitor cell treatment can cure approximately 40% of the animals with malignant gliomas with no trace of a tumo

The Role of Wind-Tunnel Studies in Integrative Research on Migration Biology

Wind tunnels allow researchers to investigate animals' flight under controlled conditions, and provide easy access to the animals during flight. These increasingly popular devices can benefit integrative migration biology by allowing us to explore the links between aerodynamic theory and migration as well as the links between flight behavior and physiology. Currently, wind tunnels are being used t

Functional expression of five Arabidopsis fatty acyl-CoA reductase genes in Escherichia coli

Very long chain primary alcohols are significant components in cuticle waxes of plants. Fatty acyl-CoA reductases (FARs) catalyze the formation of a fatty alcohol from an acyl-CoA. The Arabidopsis (Arabidopsis thaliana) genome contains eight genes homologous to FAR genes from jojoba (Simmondsia chinensis), silk moth, wheat and mouse. Expression of six Arabidopsis FAR homologs in Escherichia coli r

Housing reconstruction in disaster recovery: a study of fishing communities post-tsunami in chennai, India.

Disaster recovery after the Indian Ocean tsunami in 2004 led to a number of challenges and raised issues concerning land rights and housing reconstruction in the affected countries. This paper discusses the resistance to relocation of fishing communities in Chennai, India. Qualitative research methods were used to describe complexities in the debate between the state and the community regarding re

Determination of the Thermal Load Distribution in Internal Traverse Grinding using a Geometric-Kinematic Simulation

During grinding processes, numerous grains interact with the workpiece material producing mechanical and thermal loads on the surface. In the field of thermal simulation of grinding processes, a widely used approach is to substitute numerous cutting edges by a single moving distributed heat source of a specific geometrical shape referring to the theory of Carslaw and Jaeger. This heat source is th

Risk for incident and fatal prostate cancer in men with a family history of any incident and fatal cancer

Background: Familial clustering of incident prostate cancer and some cancers at other discordant sites has been reported. Less is known about familial clustering of fatal prostate cancer with any fatal discordant cancers. Estimates on familial aggregation based on mortality are free from bias of overdiagnosis. Patients and methods: We used the nationwide Swedish Family-Cancer Database to calculate

Scale-up Analysis of Continuous Cross-flow Atomic Layer Deposition Reactor Designs

This paper presents the development of a non-dimensional model of a continuous cross-flow atomic layer deposition (ALD) reactor with temporally separated precursor pulsing and a structured model-based methodology for scaling up the substrate dimensions. The model incorporates an ALD gas–surface reaction kinetic mechanism for the deposition of thin ZnO films from Zn(C2H5)2 and H2O precursors that w

Does easily accessible nutritional labelling increase consumption of healthy meals away from home? A field experiment measuring the impact of a point-of-purchase healthy symbol on lunch sales

This paper analyses the effect on meal consumption away from home of a point-of-purchase healthy symbol. We base the analysis on a field experiment in a lunch restaurant. Our results suggest that meal consumption does not increase if the meal is labelled with a healthy symbol. Also, the mean nutritional content of meals consumed seems unaffected by the introduction of a healthy-labelled meal on th

Medierande verktyg i körledarpraktik – en studie av arbetssätt och handling i körledning med barn och unga.

Title: Mediating tools in the practice of choir directors – a study of working approaches and actions in choral conducting with children and youth. Abstract: In Sweden, approximately 5 % of the population sing in a choir or a singing group which means that about 500 000 people plus a number of choral conductors regularly meet in choir related practices. The aim of the present study is to describ

I coachingland - på spaning efter den inre potentialen

This article examines the expansive commercialization of various neospiritual and pseudoscientific practices currently mobilized in late modern Swedish pursuits of identity, meaning, and health. The focus is on the emergence and marketing of new entrepreneurs who have established themselves as “coaches” promoting personal development, and how they organize their own systems of education and certif

Modeling the seasonality of carbon, evapotranspiration and heat processes for cold climate conditions TRITA-LWR LIC 2054. Licentiate Thesis in Land and Water Resources Engineering. KTH Architecture and the Built Environment, Stockholm

The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this

Moisture Induced Stress Perpendicular to Grain in Timber Structures

Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. Because the volume of wood is not constant but varies with the moisture content, uneven distribution of moisture will result in induced eigen-stresses because of internal restraint hyg

Contribution of indoor-generated particles to residential exposure

Abstract The majority of airborne particles in residences, when expressed as number concentrations, are generated by the residents themselves, through combustion/thermal related activities. These particles have a considerably smaller diameter than 2.5 μm and, due to the combination of their small size, chemical composition (e.g. soot) and intermittently very high concentrations, should be regard

Serum gastrin and gastric enterochromaffin-like cells during estrous cycle, pregnancy and lactation, and in response to estrogen-like agents in rats

Histamine-containing enterochromaffin-like (ECL) cells are numerous in the gastric mucosa. They operate under the. control of gastrin. ECL-cell tumors (gastric carcinoids) may arise as a consequence of sustained hypergastrinemia. For reasons unknown, such tumors have a female preponderance both in laboratory animals and humans. The present study consisted of four experiments exploring the possibil

Estimating carbon stocks in stands of Podocarpus cunninghamii in the eastern South Island high country of New Zealand

Abstract in UndeterminedThe Land-Use, Land-Use Change and Forestry (LULUCF) sector of the Kyoto Protocol requires New Zealand to monitor changes in the country’s carbon stocks, including those within indigenous forests. Podocarpus cunninghamii Colenso was, in pre-human times, a dominant tree species within the forests of the South Island high country. Anthropogenic disturbance, primarily fire, has
