Two-Line Atomic Fluorescence for Thermometry in Reactive Flows

Advances in the field of laser-based combustion diagnostics over the past decades have allowed for detailed characterisation, modelling and increased understanding of the complex combustion process. However; many combustion phenomena are still unexplained and there is a continued need for development and application of diagnostic tools to further the understanding of the combustion process.

Experimental and numerical study on bluff-body and swirl stabilized diffusion flames

Bluff-body and swirl flow are commonly utilized to stabilize diffusion flames in industrial applications, such as gas turbines, ramjets and furnaces. Flame stabilization mechanisms of these two kinds of burners are similar with each other: the interaction between the recirculation zone and the fuel jet. In the present paper, flow fields within flames stabilized by combinations of swirl flow and bl

Online purchase return policy leniency and purchase decision : Mediating role of consumer trust

Recasting prior work on return-policy and purchase intentions literature, through the lens of signaling theory and relational signaling theory, we posit that returns policy, as a market signaling mechanism, is a costly investment that online retailers make to not only support current transaction but also to signal commitment towards customer service. What outcome would such costly signal result in

Genotoxic effects of daily personal exposure to particle mass and number concentrations on buccal cells

The aim of this study is to assess personal exposure to Particle Number Concentrations (PNC) in four size ranges between 0.3 and 10 μm, and particulate matter (PM1; PM2.5; PM4; PM10) in order to evaluate possible genotoxic effects through a comet assay in buccal cells. A convenience cohort of 30 individuals from a Brazilian medium-sized city was selected. These individuals aged between 20 and 61 a

Performance of structural glass facades under extreme loads – Design methods, existing research, current issues and trends

Glass has been overwhelmingly used for windows and facades in modern constructions, for many practical reasons, including thermal, energy, light and aesthetics. Nevertheless, due to the relatively low tensile strength and mostly brittle behaviour of glass, compared to other traditional materials, as well as to a multitude of interacting structural and non-structural components, windows/facades are

Optimized efficiency in InP nanowire solar cells with accurate 1D analysis

Semiconductor nanowire arrays are a promising candidate for next generation solar cells due to enhanced absorption and reduced material consumption. However, to optimize their performance, time consuming three-dimensional (3D) opto-electronics modeling is usually performed. Here, we develop an accurate one-dimensional (1D) modeling method for the analysis. The 1D modeling is about 400 times faster

An alternative method for calibration of flow field flow fractionation channels for hydrodynamic radius determination : The nanoemulsion method (featuring multi angle light scattering)

This study suggests a novel method for determination of the channel height in asymmetrical flow field-flow fractionation (AF4), which can be used for calibration of the channel for hydrodynamic radius determinations. The novel method uses an oil-in-water nanoemulsion together with multi angle light scattering (MALS) and elution theory to determine channel height from an AF4 experiment. The method

From Pinot to Xinomavro in the world's future wine-growing regions

Predicted impacts of climate change on crops—including yield declines and loss of conservation lands—could be mitigated by exploiting existing diversity within crops. Here we examine this possibility for wine grapes. Across 1,100 planted varieties, wine grapes possess tremendous diversity in traits that affect responses to climate, such as phenology and drought tolerance. Yet little of this divers

Working Environment and work retention

The project shows that the working environment is rarely the sole cause of early retirement, but working environment factors may explain a large fraction of the transition to disability pension in particular. Several working environment predictors of early retirement are well-documented in the Nordic countries, but workplace policies and activities to retain older workers rarely aim to improve the

MMP7 modulation by short- and long-term radiotherapy in patients with rectal cancer

Background/Aim: Matrix metalloproteinase 7 (MMP7) expression is highly associated with colorectal cancer and modulates tumour growth and invasion. Radiation injury induces inflammation with increases in MMP7 and in transforming growth factor beta (TGFβ). The aim of this study was to investigate the effect on MMP7 and TGFβ. expression in patients with rectal cancer undergoing different regimens of

Multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) within an intersectional framework

Background: Analyzing Body Mass Index as a didactical example, the study by Evans, Williams, Onnela, and Subramanian (EWOS study) introduce a novel methodology for the investigation of socioeconomic disparities in health. By using multilevel analysis to model health inequalities within and between strata defined by the intersection of multiple social and demographic dimensions, the authors provide

Tidal exchange in a choked coastal lagoon : A study of Mundaú Lagoon in northeastern Brazil

Changes in the inlet morphology of choked coastal lagoons often restrict the water exchange with the sea, making them vulnerable to pollution events and eutrophication processes. In this study, the importance of tides for the water exchange was investigated in Mundaú Lagoon, which is a choked lagoon located in northeastern Brazil that has a very dynamic inlet and channel system. The analysis was c

Large Lakes Dominate CO2 Evasion From Lakes in an Arctic Catchment

CO2 evasion from freshwater lakes is an important component of the carbon cycle. However, the relative contribution from different lake sizes may vary, since several parameters underlying CO2 flux are size dependent. Here we estimated the annual lake CO2 evasion from a catchment in northern Sweden encompassing about 30,000 differently sized lakes. We show that areal CO2 fluxes decreased rapidly wi

Field experiment and numerical simulation of point source irrigation with multiple tracers

Dyes like Brilliant Blue have similar adsorptive behaviour as some organic contaminants, e.g., pesticides. Bromide ions, on the other hand, move much like NO3-N (fertilizer) in soil. Consequently, by using these two tracers, it is possible to in a general way mimic how organic contaminants and fertilizers may move through soils. Three plots with sandy soil in semiarid Tunisia were irrigated during
