Mixtures of nonionic and anionic surfactants, including Corexit 9527, were tested to determine their effects on bacterial oxidation of acetate and alkanes in crude oil by cells pregrown on these substrates. Corexit 9527 inhibited oxidation of the alkanes in crude oil by Acinetobacter calcoaceticus ATCC 31012, while Span 80, a Corexit 9527 constituent, markedly increased the oil oxidation rate. ...
OBJECTIVE To describe and compare characteristics and outcomes of patients who arrive by ambulance to the ED. We aimed to (i) compare patients with a delayed ambulance offload time (AOT) >30 min with those who were not delayed; and (ii) identify predictors of an ED length of stay (LOS) of >4 h for ambulance-arriving patients. METHODS A retrospective, multi-site cohort study was undertaken in ...
Sodium bis(2-ethylhexyl) sulfosuccinate (AOT) is well known to form nanometre sized aqueous droplets in organic solvents and used in several contemporary applications including templates of nanoparticle synthesis. However, the detailed structural characterization of AOT in aqueous media is relatively less attended. Here we have used dynamic light scattering technique for the structural characte...
We measure cross-diffusion coefficients in a five-component system, an aerosol OT (AOT) water-in-oil microemulsion loaded with two constituents of the Belousov-Zhabotinsky (BZ) reaction (H(2) O/AOT/BZ1/BZ2/octane). The species BZ1 is either NaBr, an inhibitor of the BZ reaction, or ferroin, a catalyst for the reaction. As species BZ2, we choose Br(2) , an intermediate in the reaction. The cross...
The fastest JavaScript production implementations use just-in-time (JIT) compilation and the vast majority of academic publications about dynamic languages published during last two decades focus on JIT compilation. This does not imply that static compilers (AoT) cannot be competitive; as comparatively little effort has been spent creating fast AoT compilers, a scientific comparison is lacking....
در بخشی از این کار تحقیقاتی، ترمودینامیک سیستم دو فازی triton x-100+na3c6h5o7+h2o در دمای k 298 شامل دیاگرام فاز و منحنی باینودال به صورت تجربی به دست آمد. نتایج به دست آمده مربوط به دیاگرام فاز این سیستم با مدل ویریال اصلاح شده برازش شد و تطابق خوبی بین مقادیر تجربی و تئوری حاصل گردید. هم¬چنین رفتار توزیعی سه آمینواسید l-فنیل¬آلانین، l-تریپتوفان و l-تیروزین در این سیستم مورد مطالعه قرار گرفت و...
Using 1 year of aerosol optical thickness (AOT) retrievals from the MODerate resolution Imaging Spectro-radiometer (MODIS) on board NASA’s Terra and Aqua satellite along with ground measurements of PM2.5 mass concentration, we assess particulate matter air quality over different locations across the global urban areas spread over 26 locations in Sydney, Delhi, Hong Kong, New York City and Switz...
A typical scene category, e.g., street and beach, contains an enormous number (e.g., in the order of 10 to 10) of distinct scene configurations that are composed of objects and regions of varying shapes in different layouts. A well-known representation that can effectively address such complexity is the family of compositional models; however, learning the structures of the hierarchical composi...
Errors in estimating and forecasting often result from the failure to collect and consider enough relevant information. We examine whether attributes associated with persistence in information acquisition can predict performance in an estimation task. We focus on actively open-minded thinking (AOT), need for cognition, grit, and the tendency to maximize or satisfice when making decisions. In th...
We present a fixed-lag ensemble Kalman smoother for estimating emissions for a global aerosol transport model from remote sensing observations. We assimilate AERONET AOT and AE as well as MODIS Terra AOT over ocean to estimate the emissions for dust, sea salt and carbon aerosol and the precursor gas SO2. For January 2009, globally dust emission decreases by 26% (to 3,244 Tg/yr), sea salt emissi...
