Prise en charge officinale de la dermatite atopique
The treatment of atopic dermatitis in the community pharmacy is not simply a case of dispensing medication. It is also important to develop prevention strategies for people at high risk (primary prevention), as well as for individuals with a recently diagnosed atopic allergy (secondary prevention)
Sky Variability in the y Band at the LSST Site
We have measured spatial and temporal variability in the y band sky
brightness over the course of four nights above Cerro Tololo near Cerro Pachon,
Chile, the planned site for the Large Synoptic Survey Telescope (LSST). Our
wide-angle camera lens provided a 41 deg field of view and a 145 arcsec pixel
scale. We minimized potential system throughput differences by deploying a deep
depletion CCD and a filter that matches the proposed LSST y_3 band (970 nm-1030
nm). Images of the sky exhibited coherent wave structure, attributable to
atmospheric gravity waves at 90 km altitude, creating 3%-4% rms spatial sky
flux variability on scales of about 2 degrees and larger. Over the course of a
full night the y_3 band additionally showed highly coherent temporal
variability of up to a factor of 2 in flux. We estimate the mean absolute sky
level to be approximately y_3 = 17.8 mag (Vega), or y_3 = 18.3 mag (AB). While
our observations were made through a y_3 filter, the relative sky brightness
variability should hold for all proposed y bands, whereas the absolute levels
should more strongly depend on spectral response. The spatial variability
presents a challenge to wide-field cameras that require illumination correction
strategies that make use of stacked sky flats. The temporal variability may
warrant an adaptive y band imaging strategy for LSST, to take advantage of
times when the sky is darkest.Comment: 8 pages, 5 figures, accepted to PASP. Minor changes from referee

The Effect of Substituting High Oil Corn as a Replacement for Normal Corn in Nursery Pig Diets
The objective of this study was to determine the production and monetary effects of using High Oil Corn (HOC) in a nursery phase feeding program and monitor growth performance differences through marketing. Two groups of weaned crossbred pigs (n = 293 trial 1; n = 265 trial 2) were segregated by sex and weight into small, medium and heavy groups and allotted to 12 nursery pens. Pigs received one of two dietary treatments which included; a transitional phase I diet for 7 days; a commercial corn soy based phase II diet (NCII) for 14 days and a phase III diet (NCIII) for 7 days; a HOC soy based phase II diet for 21 days and the NCIII diet for 7 days. Body weight, Average daily feed intake and Gain/Feed (G/F) ratios were measured weekly during the nursery period. Pigs were transferred to a grow/finish barn on d 28 post-weaning. Body weight, Backfat (BF) and Longissimus Muscle Area (LMA) at the 10th and last ribs were ultrasonically evaluated 4 times prior to market. Average daily gain of nursery pigs on the three-phase NC diet was greater than pigs fed the HOC two-phase diet at d 21 post-weaning (p = .0034) and 28 post-weaning (p = .0128). ADG for heavy pigs was greater (p = .0001) than that of medium and lightweight pigs and no treatment�weight group interactions were observed (p = .2043). Pigs fed the three-phase diet had greater G/F ratios than pigs fed the HOC two-phase diet at d 21 (p = .0137) and 28 (p = .0134). LEA for pigs fed the three-phase diet was greater than pigs fed the HOC two-phase diet when measured on d 28 at the 10th (p = .0565) and last rib (p = .0370). Even though pigs were fed alike in the grow-finish period, ADG of pigs fed the three-phase nursery diet was greater (p = .0106) than that of pigs fed the HOC two-phase nursery diet. There were no differences in the predicted 114 kg weight (p = .2658). However, economic differences were noted for the two treatments with the HOC two-phase diet lowering the cost of production of marketed animals. There were no treatment differences for average daily lean growth per day (p = .8611) or percentage lean of carcasses (p = .2865). The results did not support removal of the transitional phase I diet and the substitution of HOC for NC in a phase II diet fed to nursery pigs for maximal nursery growth, nor was carcass composition of pigs at marketing adversely affected
A Comparison of Intrauterine and Cervical Artificial Insemination Catheters on Farrowing Rate and Litter Size in Artificially Mated Sows
The objectives of this study were to determine the effects of artificial insemination (AI) catheter type on litter size and farrowing rate. No performance difference was found between sows artificially inseminated using intrauterine or intracervical methods. Since intrauterine catheters typically are more expensive, there is an economic advantage for the more commonly used intracervical method of artificial insemination in the present study
The Pulsed Neutron Beam EDM Experiment
We report on the Beam EDM experiment, which aims to employ a pulsed cold
neutron beam to search for an electric dipole moment instead of the established
use of storable ultracold neutrons. We present a brief overview of the basic
measurement concept and the current status of our proof-of-principle Ramsey
apparatus
