Quantitative measurement of hydroxyl radical (OH) concentration in premixed flat flame by combining laser-induced fluorescence and direct absorption spectroscopy

An accurate and reasonable technique combining direct absorption spectroscopy and laser-induced fluorescence (LIF) methods is developed to quantitatively measure the concentrations of hydroxyl in CH4/air flat laminar flame. In our approach, particular attention is paid to the linear laser-induced fluorescence and absorption processes, and experimental details as well. Through measuring the tempera

How system quality influences mobile BI use : The mediating role of engagement

Despite the recognized value that mobile BI (m-BI) brings to firms, our understanding of the use of m-BI and its determinants are limited. In this study, we suggest that m-BI system quality characteristics may be among the factors that influence m-BI use. Yet, in the information systems (IS) literature there is mixed support for the relationship between system quality and system use at the individ

Accounting for interannual variability in agricultural intensification : The potential of crop selection in Sub-Saharan Africa

Providing sufficient food for a growing global population is one of the fundamental global challenges today. Crop production needs not only to be increased, but also remain stable over the years, in order to limit the vulnerability of producers and consumers to inter-annual weather variability, especially in areas of the world where the food consumed is mainly produced locally (e.g. Sub Saharan Af

Assortativity Evolving from Social Dilemmas

Assortative mechanisms can overcome tragedies of the commons that otherwise result in dilemma situations. Assortativity criteria include various forms of kin selection, greenbeard genes, and reciprocal behaviors, usually presuming an exogenously fixed matching mechanism. Here, we endogenize the matching process with the aim of investigating how assortativity itself, jointly with cooperation, is dr

The Role of Private Actors in Public Sector Innovation

The changing forms of governance stemming from the rise of New Public Management (NPM) and New Public Governance (NPG) have brought about significant changes in the relationship between the public and private sectors (Christensen and Lægreid 2007; Torfing and Triantafillou 2013). Not only have we witnessed a gradual increase in the involvement of private actors in the provision of public services,

Industrial and geographical mobility of workers during industry decline : The Swedish and German shipbuilding industries 1970–2000

This article follows the industry employment histories of all individuals who at some point have been affiliated with the declining German or the dismantling Swedish shipbuilding industry during 1970–2000. We analyse the situation of the individual workers leaving shipbuilding, investigating the extent to which they were employed at all, tended to move to related sectors within or outside the regi

Spatial and Physical Splittings of Semilinear Parabolic Problems

För att skapa matematiska beskrivningar av fysiska fenomen inom bland annat naturvetenskap, teknik och medicin används ofta partiella differentialekvationer. Listan med tillämpningar kan göras hur lång som helst: sådana ekvationer kan beskriva hur en snöflinga bildas, hur strukturer deformeras när de utsätts för mekaniska krafter, hur partiklar interagerar på kvantnivå, hur blodet flödar i hjärnanSplitting methods are widely used temporal approximation schemes for parabolic partial differential equations (PDEs). These schemes may be very efficient when a problem can be naturally decomposed into multiple parts. In this thesis, splitting methods are analysed when applied to spatial splittings (partitions of the computational domain) and physical splittings (separations of physical processes)

Extended Law of Corresponding States Applied to Solvent Isotope Effect on a Globular Protein

Investigating proteins with techniques such as NMR or neutron scattering frequently requires the partial or complete substitution of D2O for H2O as a solvent, often tacitly assuming that such a solvent substitution does not significantly alter the properties of the protein. Here, we report a systematic investigation of the solvent isotope effect on the phase diagram of the lens protein gamma B-cry

Does Debt Relief Improve Child Health? Evidence from Cross-Country Micro Data

This paper analyzes the effects of a multilateral debt relief program on child health. The International Monetary Fund and the World Bank launched the Heavily Indebted Poor Countries Initiative in the late 1990s to reduce the debt burdens of poor countries, and explicitly linked the initiative to the aim of poverty reduction and social targets. As a result, debt-servicing costs have gone down by a

Behavioral Analysis of Dopaminergic Activation in Zebrafish and Rats Reveals Similar Phenotypes

Zebrafish is emerging as a complement to mammals in behavioral studies; however, there is a lack of comparative studies with rodents and humans to establish the zebrafish as a predictive translational model. Here we present a detailed phenotype evaluation of zebrafish larvae, measuring 300-3000 variables and analyzing them using multivariate analysis to identify the most important ones for further

The translationally relevant mouse model of the 15q13.3 microdeletion syndrome reveals deficits in neuronal spike firing matching clinical neurophysiological biomarkers seen in schizophrenia

AIM: To date, the understanding and development of novel treatments for mental illness is hampered by inadequate animal models. For instance, it is unclear to what extent commonly used behavioural tests in animals can inform us on the mental and affective aspects of schizophrenia.METHODS: To link pathophysiological processes in an animal model to clinical findings, we have here utilized the recent

Sustainable Supply Chain Management in Food Retailing : Insights into corporate practice of managing supplier relationships

Addressing sustainability concerns in supply chain operations can be a matter of long-term business survival for food retailers. However, regardless of whether it is perceived as a risk or market opportunity, acting across the value chain to address unsustainable production and consumption practices has been a constant challenge. This thesis investigated the sustainable supply chain management (SS

Bowel irradiation: the effects on inflammation and matrix-metalloproteinases

Background and aims: Radiotherapy is a valid treatment in cancer multimodal management but it is affected by severe systemic and local side effects. A murine small bowel model was used for the investigation of inflammatory features and apoptosis of local radiotherapy. Similarly the same model was used to analyze the combined effects of radiotherapy and antibiotics in the expression of matrilysin,

Linking ecological debt and ecologically unequal exchange: stocks, flows, and carbon sink appropriation

Ecological debt is usually conceptualized as the accumulated result of different kinds of uneven flows of natural resources and waste, but these flows are seldom referred to as ecologically unequal exchange. Ecologically unequal exchange, on the other hand, is usually defined as different flows of resources and waste, but the accumulated results of these flows are seldom referred to as ecological

Condition and reproductive investment in the western mosquitofish (Gambusia affinis) : little evidence for condition-dependent sex-biased investment

In sexually reproducing species, resources may theoretically be distributed with bias to the production of male or female offspring in response to the condition of the mother, commonly recognized as sex allocation. Using a recently characterized sex-specific molecular marker, we tested for maternal sex allocation (i.e. maternal primary sex ratio bias and sex-specific offspring investment) in capti

Thermal expansion in UO2 determined by high-energy X-ray diffraction

Here we present crystallographic analyses of high-energy X-ray diffraction data on polycrystalline UO2 up to the melting temperature. The Rietveld refinements of our X-ray data are in agreement with previous measurements, but are systematically located around the upper bound of their uncertainty, indicating a slightly steeper trend of thermal expansion compared to established values. This observat

In situ time-of-flight neutron imaging of NiO-YSZ anode support reduction under influence of stress

This article reports on in situ macroscopic scale imaging of NiO-YSZ (YSZ is yttria-stabilized zirconia) reduction under applied stress - a phase transition taking place in solid oxide electrochemical cells in a reducing atmosphere of a hydrogen/nitrogen mixture and at operation temperatures of up to 1073K. This process is critical for the performance and lifetime of the cells. Energy-resolved neu

Beta-delayed proton emission from 20 Mg has been measured at ISOLDE, CERN, with the ISOLDE Decay Station (IDS) setup including both charged-particle and gamma-ray detection capabilities. A total of 27 delayed proton branches were measured including seven so far unobserved. An updated decay scheme, including three new resonances above the proton separation energy in 20 Na and more precise resonance

Solvatochromism of dye-labeled dendronized polymers of generation numbers 1–4: comparison to dendrimers

Two series of dendronized polymers (DPs) of generations g = 1–4 with different levels of dendritic substitution (low and high) and a solvatochromic probe at g = 1 level are used to study their swelling behavior in a collection of solvents largely differing in polarity as indicated by the Kamlet–Taft parameters. This is done by measuring the UV-Vis spectra of all samples in all solvents and determi
