Aging effects on the properties of imidazolium, quaternary ammonium, pyridinium and pyrrolidinium-based ionic liquids used in fuel and energy production

by Elise B Fox , L Taylor Smith , Tyler K Williamson , Sarah E Kendrick
"... Ionic liquids are often cited for their excellent thermal stability, a key property for their use as solvents and in the chemical processing of biofuels. However, there has been little supporting data on the long term aging effect of temperature on these materials. Imizadolium, quaternary ammonium, ..."

, pyridinium, and pyrrolidnium-based ionic liquids with the bis(trifluoromethylsulfonyl)imide and bis(perfluoroethylsulfonyl)imide anions were aged for 2520 hours (15 weeks) at 200°C in air to determine the effects of an oxidizing environment on their chemical structure and thermal stability over time

M Tangermann, A New Auditory Multi-class BrainComputer Interface Paradigm: Spatial Hearing as an Informative Cue. PLoS ONE. 5(4):e9813

by Martijn Schreuder, Benjamin Blankertz, Michael Tangermann , 2010
"... Most P300-based brain-computer interface (BCI) approaches use the visual modality for stimulation. For use with patients suffering from amyotrophic lateral sclerosis (ALS) this might not be the preferable choice because of sight deterioration. Moreover, using a modality different from the visual one ..."

Corresponding information transfer rates were high, up to an average score of 17.39 bits/minute for the 175 ms condition (best subject 25.20 bits/minute). When presenting the stimuli through a single speaker, thus effectively canceling the spatial

Nomenclature

"... Abstract: Coconut coir is an agricultural waste that is produced in reasonable quantities in some developing countries of the world like Nigeria. This waste is used in some evaporative cooling systems as cooling media. This paper therefore attempts to analyze the performance of coconut coir pad as a ..."

as a media in direct evaporative coolers. In this study, the average condition of 39.9 0C dry bulb temperature and 8.1 % relative humidity of Kano is selected for the analysis. The primary air mass flow rate considered varies between 0.16 kg/s to 0.54kg/s and the performance of the coconut coir pad

Responses of Photosynthetic Functions to Low Temperature in Flag Leaves of Rice Genotypes at the Milky Stage

by Jing Wang , Zhang Cheng-Jun , Chen Guo-Xiang , Ping Wang , Shi Da-Wei , L U Chuan-Gen , 2006
"... Abstract: To examine the chilling resistance of a newly developed super hybrid rice (Oryza sativa) Liangyou 122 at the different temperatures, an experiment was conducted to investigate the photosynthetic pigments contents, changes in fatty acids content of thylakoid membrane and the activities of ..."

Respiratory Syncytial Virus in the United

by Glen R. Abedi, Larry J. Anderson, Lynnette Brammer, David K. Shay
"... Background. Age-specific comparisons of influenza and respiratory syncytial virus (RSV) hospitalization rates can inform prevention efforts, including vaccine development plans. Previous US studies have not estimated jointly the burden of these viruses using similar data sources and over many season ..."

-years, respectively. The highest hospitalization rates for influenza were among persons aged $65 years (309/100 000; 95 % CI, 186–1100) and those aged,1 year (151/100 000; 95 % CI, 151–660). For RSV, children aged,1 year had the highest hospitalization rate (2350/100 000; 95 % CI, 2220–2520) followed by those aged 1

Modeling of Nutation-Precession: Very long baseline interferometry results

by Herring Department Of, T. A. Herring, P. M. Mathews, B. A. Buffett , 2000
"... Analysis of over 20 years of very long baseline interferometry data (VLBI) yields estimates of the coefficients of the nutation series with standard deviations ranging from 5 micro-arc-seconds (mas) for the terms with periods less than 400-days to 38 mas for the longest period terms. The largest dev ..."

. The secular change in the obliquity of the ecliptic is estimated to be-0.2520.003 mas/yr. When the coefficients of the largest amplitude terms in the nutation series are estimated, the precession constant correction and obliquity rate are estimated to be-2.9600.030 mas/yr and-0.2370.012 mas/yr. Significant

An Assessment of Petroleum Prices Recent Trends

OPEN ORIGINAL ARTICLE Maternal depression is associated with DNA methylation changes in cord blood T lymphocytes and adult hippocampi

by Z Nemoda, R Massart, M Suderman, M Hallett, T Li, M Coote, N Cody, Zs Sun, Cn Soares, G Turecki, M Steiner
"... Depression affects 10–15 % of pregnant women and has been associated with preterm delivery and later developmental, behavioural and learning disabilities. We tested the hypothesis that maternal depression is associated with DNA methylation alterations in maternal T lymphocytes, neonatal cord blood T ..."
