The temperature dependence of the laminar burning velocity of ethanol flames

The Heat Flux method was extended for the first time towards liquid fuels and used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. Uncertainties of the measurements were analyzed and assessed experimentally. The overall accuracy of the burning velocities was est

Electron microscopy study of single crystal BaZr0.9Y0.1O3-x films prepared by chemical solution deposition

Single crystal thin films of 10% yttrium doped barium zirconate (BZY10) have been prepared using chemical solution deposition on magnesium oxide substrates and annealed at 800 or 1000 degrees C. A focused ion beam lift out technique was used to prepare thin (< 100 nm) specimens for transmission electron microscopy (TEM) analysis. A variety of TEM based techniques were used for characterization, in

Osmotic processing: Effects of osmotic medium composition on the kinetics and texture of apple tissue

The effect of modification of osmotic medium composition with salts on the texture changes and process kinetics was evaluated in the present study. Inner and outer apple cortex parenchyma (Kim var.) was subjected to osmotic processing at 20.40 and 60 degrees C. The four osmotic media used were of identical osmotic pressure but slightly different compositions. The solution 1, Si, was a 50% w/w sucr

Comparison and Evaluation of Multiple Users' Usage of the Exposure and Risk Tool: Stoffenmanager 5.1.

Stoffenmanager is an exposure and risk assessment tool that has a control banding part, with risk bands as outcome and a quantitative exposure assessment part, with the 90th percentile of the predicted exposure as a default outcome. The main aim of the study was to investigate whether multiple users of Stoffenmanager came to the same result when modelling the same scenarios. Other aims were to inv

Structure and Bonding of an Intergrowth Phase Ca7Ag2+xGe7-x (x approximate to 2/3) Featuring a Zintl-Type Polyanionic Chain

Single crystals of a new ternary phase, Ca7Ag2+xGe7-x [x = 0.48(3)], were obtained from as side-product of high-temperature solid-state reactions, and its crystal structure determined by X-ray diffraction methods. Following the Zintl concept, the anionic substructure consists of a novel pentameric Zintl anion [Ge-5](12-) with C-2v local symmetry, as well as [AgxGe2-x]((6-3x)-) units accounting for

Search for anomalous production of prompt like-sign lepton pairs at root s=7 TeV with the ATLAS detector

An inclusive search for anomalous production of two prompt, isolated leptons with the same electric charge is presented. The search is performed in a data sample corresponding to 4.7 fb(-1) of integrated luminosity collected in 2011 at root s = 7TeV with the ATLAS detector at the LHC. Pairs of leptons (e(+/-)e(+/-), e(+/-)mu(+/-), and mu(+/-)mu(+/-)) with large transverse momentum are selected, an

Search for top quark decays t -> q H with H -> gamma gamma using the ATLAS detector

A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons. The proton-proton collision data set used corresponds to 4.7 fb(-1) at root s = 7TeV and 20.3 fb(-1) at root s = 8TeV collected by the ATLAS experiment at the LHC. Top quark pair events are searched for in which one top q

Risk Factors That Affect Life Expectancy in Alzheimer's Disease: A 15-Year Follow-Up.

Backgrounds/Aims: Future disease-modifying therapies might affect the expected life span in Alzheimer's disease (AD). Our aim was to identify factors that influence life expectancy in cholinesterase inhibitor (ChEI)-treated patients. Methods: This study included 791 deceased individuals with a clinical diagnosis of AD and a Mini-Mental State Examination score of 10-26 at baseline who were recruite

Selection of adsorbents for treatment of leachate: batch studies of simultaneous adsorption of heavy metals

The simultaneous adsorption of copper (Cu), cadmium (Cd), nickel (Ni), and lead (Pb) ions from spiked deionized water and spiked leachate onto natural materials (peat A and B), by-product or waste materials (carbon-containing ash, paper pellets, pine bark, and semi-coke), and synthetic materials (based on urea-formaldehyde resins, called blue and red adsorbents) or mixtures thereof was investigate

Winners and losers of organic cereal farming in animal communities across Central and Northern Europe

Organic farming is promoted as a sustainable alternative to conventional farming, with positive effects on the diversity of plants and selected animal taxa. Here, we used a literature survey to collect presence/absence data on the composition of farmland bird, ground beetle, spider as well as butterfly and moth communities from 28 independent studies to identify genera and (sub-)families that had

Elderly People's Perceptions of a Telehealthcare System: Relative Advantage, Compatibility, Complexity and Observability

The use of telehealthcare systems to promote independent living for elderly people is growing. The results presented in this article, derived from an initial user lab test of a telecare system—GiraffPlus—indicate that the crucial factor for adoption of telehealthcare systems is not usability but the system's ability to support autonomy in everyday life. Eleven users tested the usability and report

Long-term effect of aspirin on colorectal cancer incidence and mortality: 20-year follow-up of five randomised trials

Background High-dose aspirin (>= 500 mg daily) reduces long-term incidence of colorectal cancer, but adverse effects might limit its potential for long-term prevention. The long-term effectiveness of lower doses (75-300 mg daily) is unknown. We assessed the effects of aspirin on incidence and mortality due to colorectal cancer in relation to dose, duration of treatment, and site of tumour. Methods

Communication of Corporate Social Responsibility: A Study of the Views of Management Teams in Large Companies

In light of the many corporate scandals, social and ethical commitment of society has increased considerably, which puts pressure on companies to communicate information related to corporate social responsibility (CSR). The reasons underlying the decision by management teams to engage in ethical communication are scarcely focussed on. Thus, grounded on legitimacy and stakeholder theory, this study

Outcome of patients developing GVHD after DLI given to treat CML relapse: a study by the chronic leukemia working party of the EBMT

We studied GVHD after donor lymphocyte infusion (DLI) in 328 patients with relapsed CML between 1991 and 2004. A total of 122 patients (38%) developed some form of GVHD. We analyzed GVHD by clinical presentation (acute or chronic GVHD) and onset time after the first DLI (early (45 days)). There was a significant overlap between onset time and clinical presentation. Some form of GVHD occurred at a

Clonal alteration of breast cancer receptors between primary ductal carcinoma in situ (DCIS) and corresponding local events

Background: Emerging data propose biomarker alteration due to clonal selection between the primary invasive breast cancer and corresponding metastases. In addition, impact on survival has been demonstrated. The present study investigates the relationship between the oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) between primary ductal carcin

Glucose and xylose co-fermentation of pretreated wheat straw using mutants of S. cerevisiae TMB3400.

Wheat straw was pretreated and fermented to ethanol. Two strains, which had been mutated from the genetically modified Saccharomyces cerevisiae TMB3400, KE6-12 and KE6-13i, have been used in this study and the results of performance were compared to that of the original strain. The glucose and xylose co-fermentation ability was investigated in batch fermentation of steam-pretreated wheat straw (SP

Assessment of Body Composition in Subjects with Metabolic Syndrome Comparing Single-Frequency Bioelectrical Impedance Analysis and Bioelectrical Spectroscopy.

Abstract Background: The aim of this study was to investigate the agreement between body composition measurements made with two methods-single-frequency bioelectrical impedance analysis (SF-BIA) and bioelectrical impedance spectroscopy (BIS). Methods: The body composition measurements using SF-BIA and BIS were performed seven times during 6 months on 41 patients (13 men and 28 women) with metaboli
