Large Eddy Simulation (LES) was employed to investigate the fuel/oxidizer mixing process in an ethylene fueled scramjet combustor with a rearwall-expansion cavity. The numerical solver was first validated for an experimental flow, the DLR strut-based scramjet combustor case. Shock wave structures and wall-pressure distribution from the numerical simulations were compared with experimental data and

The majority of microarray studies evaluate gene ex- pression differences between various specimens or con- ditions. However, the causes of this variability often re- main unknown. Our aim is to identify underlying causes of these patterns, a process that would eventually enable a mechanistic understanding of the deregulation of gene expression in cancer. The procedure consists of three phases: pr

The objective of cancer treatment is to secure survival. However, as chemotherapeutic agents can affect the central and peripheral nervous systems, patients must undergo a process of central compensation. We explored the effectiveness of this compensation process by measuring postural behaviour in adult survivors of childhood cancer treated with chemotherapy (CTS). We recruited sixteen adults trea

Nation branding is a remarkable phenomenon. In less than two decades, it has established itself as the preferred framework for interstate strategic communication and as an emerging academic field. The paper describes how this extraordinary expansion was possible by showing how nation branding presents itself as a theoretical possibility and a practical necessity. We propose that what made a travel

Admission to an emergency department can be considered a stressful event for both the child and the family. Due to the nature of traumas, illnesses and fatalities it is a chaotic forum in which good communication between child and staff can be difficult to establish. Purpose: The purpose of the study was to describe nurses' methods when interacting with children aged three to six at a pediatric em

This study examines the governance attributes of post-IPO (initial public offering) retained ownership of private equity in business group constituent firms in contrast to their unaffiliated counterparts, in 202 newly listed firms in 22 emerging African economies. We adopt an actor centered institutional-theoretic perspective in rationalizing institutional voids and the advantages of maintained go

Quantitative concentrations measurements using time-resolved laser-induced fluorescence have been demonstrated for nitric oxide (NO) in flame. Fluorescence lifetimes measured using a picosecond Nd:YAG laser and optical parametric amplifier system have been used to directly compensate the measured signal for collisional quenching and evaluate NO concentration. The full evaluation also includes the

The release of alkali metals (Na and K) during biomass pyrolysis was numerically and experimentally investigated using Laser-Induced Breakdown Spectroscopy technique that could extend the measurements of alkali metal concentration to the sooty pyrolysis stage. Two distinct peaks of metal concentrations were observed at the pyrolysis stage and at the gasification stage. Since during the pyrolysis s

In many species of phytoplankton, simple photoreceptors monitor ambient lighting. Photoreceptors provide a number of selective advantages including the ability to assess the time of day for circadian rhythms, seasonal changes, and the detection of excessive light intensities and harmful UV light. Photoreceptors also serve as depth gauges in the water column for behaviors such as diurnal vertical m

Summary: The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data show that this material is not genotoxic nor does it have skin sensitiza

Objectives: To explore chimney sweeping work tasks, chimney sweeps’ use of protective equipment, and type of fuel used by clients, over time. Further, to assess work-relatedness of current eye and airway symptoms. Methods: In a cross-sectional study in 2011, male Swedish chimney sweeps (n = 483; age 21–69 years) answered a questionnaire about their occupational history and eye and airway symptoms.

Chromatophores, with chemically identified pigment, from the body and eyes of crustaceans were investigated ultrastructurally. Red carotenoid-, black ommochrome-, and white pteridine-containing chromatophores were found to have pigment granules of different morphological appearance.

The ultrastructure of the paired nerves, previously called frontal organ or X-organ, in copepod crustaceans was investigated. These nerves, run- ning from the anterior margin of the brain to the frontal edge of the animals, are found to contain the dendrites of three types of morpho- logically different sensory neurons. The first unit consists of two dendrites (distinguished by their myelinization

PURPOSE OF THE REVIEW: The controversies surrounding perioperative antimicrobial prophylaxis (AMP) are about the use and especially misuse of antibiotics. The overall lack of evidence to facilitate a rational perioperative AMP policy in urological surgery and the postoperative infectious complications remain a challenge. Therefore, a basic tool to aid decision-making would be useful. A model based

The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data from the suitable read across analog linalool (CAS # 78-70-6) show that this mate
