OBJECTIVES The purpose of this study was to determine factors associated with use of emergency departments by African American, Latino, and White children aged 1-11 years in California. METHODS I conducted a secondary analysis of parental reports of emergency department use by children with asthma (defined as doctor's diagnosis of asthma). An overall sample of 1313 children with asthma was id...

The routine pretransfusion red blood cell antibody detection test (PADT), performed at the authors' institution, consists of a threephase, saline-antiglobulin technique (immediate spin, 30-minute incubation at 37 °C, IgG indirect antihuman globulin test |IAT|), and each phase is examined for hemolysis and agglutination. To determine if it would be safe to omit reading the 37 °C phase of the PAD...

We study the evolution of a one-dimensional pile, empty at rst, which receives a grain in its rst stack at each iteration. The nal position of grains is singular: grains are sorted according to their parity. They are sorted on trapezoidal areas alternating on both sides of a diagonal line of slope p 2. This is explained and proved by means of a local study. Each generated pile, encoded in heigh...

The spatial frequency selectivity of motion detection mechanisms can be measured by comparing the magnitude of motion aftereffects (MAEs) as a function of the spatial frequency of the adapting and test gratings. For static test gratings, narrow spatial frequency tuning has been reported in a number of studies. However, for dynamic test patterns, reports have been conflicting. Ashida & Osaka [(1...

1313 E. 60th Street, Chicago 37, Illinois. 30 cents. Although based on American experience, this brief pamphlet should be of interest to all workers concerned about the increasing number of senile patients in our mental hospitals. It is a report on the provision of specialized boarding home care for patients from the state hospitals of North Carolina, many "having been admitted there when menta...

NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available ESO VLT and HST data have appeared in the literature. Here, we present our analysis of VLT/FORS1 and HST/ACS photometric data, confirming the identification of the B ∼ 23 mag blue optical counterpart. We show that the system is part of a...

BACKGROUND Bioethanol production processes involve enzymatic hydrolysis of pretreated lignocellulosic biomass into fermentable sugars. Due to the relatively high cost of enzyme production, the development of potent and cost-effective cellulolytic cocktails is critical for increasing the cost-effectiveness of bioethanol production. In this context, the multi-protein cellulolytic complex of Clost...

The presence of a cool multicolor disk component with an inner disk temperature kT = 0.1 ∼ 0.3 keV at a luminosity L > 10 40 ergs s −1 has been interpreted as evidence that the ultraluminous X-ray source NGC 1313 X-2 harbors an intermediate-mass black hole (IMBH). The temperature of a disk component should vary with luminosity as L ∝ T 4. However, upon investigating the spectral evolution with ...
