Flame investigations of a laboratory-scale CECOST swirl burner at atmospheric pressure conditions

Experimental and numerical studies were performed to understand the stabilization of lean premixed natural gas/air flames in a gas turbine model combustor which was equipped with a swirl burner, known as the CECOST burner, designed to replicate the flow and flame structures in an industrial gas turbine engine. The operability range, flame stabilization, and flashback were investigated employing si

Pheromone dialects in European turnip moths Agrotis segetum

Female pheromone gland extracts from cultures of Agrotis segetum originating from Sweden, France, Hungary and England were analysed for pheromone components and precursors (fatty acids). The pheromone blends were similar in moths from the Swedish, English and Hungarian populations, whereas the French diverged with a much higher amount of (Z)-7-decenyl acetate relative to the homologous pheromone c

Sex pheromone precursors in two primitive New Zealand tortricid moth species

Female pheromone gland extracts of two primitive New Zealand tortricid species that use (Z)-8-tetradecenyl acetate as a pheromone component were analyzed for pheromone precursors. Both Planotortrix excessana and Ctenopseustis obliquana contained (Z)-8-tetradecenoate as well as large amounts of (Z)-10-hexadecenoate. We propose that (Z)-8-tetradecenyl acetate is synthesized from hexadecanoate (palmi

Determination of the Double Bond Position in Monounsaturated Acetates from Their Mass Spectra

A simple method of widespread applicability in determining double bond positions in C12, C14, and C16 straight-chain monounsaturated acetates is presented. The analysis is made with a capillary gas chromatograph coupled to a low-resolution mass spectrometer which is operated in the electron impact mode. No chemical derlvatlzation of the unknowns is needed. Five pairs of selected mass spectral frag

SEX PHEROMONE OF THE CONE PYRALID DIORYCTRIA ABIETELLA

Gas chromatographic analyses coupled with electro‐antennographic detection indicated that (Z,E)‐9,11‐tetradecadienyl acetate (Z,E‐9,11–14Ac) is a pheromone component of the cone pyralid Dioryctria abietella. Gas chromatographic − mass spectrometric analyses confirmed the presence of a tetradecadienyl acetate with mass spectrum and retention index identical to Z,E‐9,11–14Ac. A receptor cell sensiti

Human behaviour in road tunnel safety design: evacuation modelling vs Italian Risk Analysis Method (IRAM)

Road tunnel fires are non-recurrent events which have led the researchers to investigate on the best risk analysis methodology. At the moment, the European Directive 2004/54/EC on minimum safety requirements for tunnels in the Trans-European road network gives only general statements. Consequently, practitioners have often difficulties to define the best way to ensure the desired safety conditions

A Glossary for Research on Human Crowd Dynamics

This article presents a glossary of terms that are frequently used in research onhuman crowds. This topic is inherently multidisciplinary as it includes work in and across computer science, engineering, mathematics, physics, psychology and social science, for example. We do not view the glossary presented here as a collection of finalised and formal definitions. Instead, we suggest it is a snapsho

Distinctive alteration in the expression of autophagy genes in Drosophila models of amyloidopathy and tauopathy

BACKGROUND: Alzheimer's disease (AD) is one the most common types of dementia. Plaques of amyloid beta and neurofibrillary tangles of tau are two major hallmarks of AD. Metabolism of these two proteins, in part, depends on autophagy pathways. Autophagy dysfunction and protein aggregation in AD may be involved in a vicious circle. The aim of this study was to investigate whether tau or amyloid beta

Mobility of near surface MOVPE grown InGaAs/InP quantum wells

In this work, we study the electron mobility of near surface metal organic vapor phase epitaxy-grown InGaAs quantum wells. We utilize Hall mobility measurements in conjunction with simulations to quantify the surface charge defect density. Buried quantum wells are limited by polar optical phonon scattering at room temperature. In contrast, the quantum wells directly at the surface are limited by r

A parametric study on cavitation flow through steam trap valves under high pressure difference

Steam trap valves are mainly used in thermal power systems to pour out condensate water and keep steam inside. While flowingthrough steam trap valves, the condensate water is easy to reach cavitation, which may cause serious damage to the pipingsystem. In this paper, in order to suppress cavitation inside steam trap valves, effects of valve body geometrical parametersincluding orifice diameter, in

Target position uncertainty during visually guided deep-inspiration breath-hold radiotherapy in locally advanced lung cancer

Purpose The purpose of this study was to estimate the uncertainty in voluntary deep-inspiration breath-hold (DIBH) radiotherapy for locally advanced non-small cell lung cancer (NSCLC) patients. Methods Perpendicular fluoroscopic movies were acquired in free breathing (FB) and DIBH during a course of visually guided DIBH radiotherapy of nine patients with NSCLC. Patients had liquid markers injected

Letter to the editor : Indacaterol/glycopyrronium/mometasone furoate compared with salmeterol/fluticasone propionate in patients with asthma: A randomized controlled cross-over study

Indacaterol (IND; 150 μg), glycopyrronium (GLY; 50 μg) and mometasone furoate (MF; 160 μg [high-dose ICS] and 80 μg [medium-dose ICS]) have been formulated as a once-daily (o.d.) fixed-dose combination treatment delivered via the Breezhaler® device for the treatment of patients with asthma. In this randomized (n = 116), double-blind, double-dummy, active comparator-controlled, three-period cross-o

Responsible selves

This title was first published in 2001. In the Nordic countries women are considered equal to men. Advanced social and economic rights are often given as the explanation for the equality. In this volume, Nordic feminist legal scholars give a more contradictory image of gender equality. The gendered construction of the legal subject and the legal understanding of gender have a two-pronged potential
