Is DEET safe for children?
(Family Physicians Inquiries Network, 2005)
Reported evidence suggests that DEET use is safe for children older than 2 months, with only very rare incidence of major adverse effects (strength of recommendation [SOR]: C). Typically, a topical concentration between ...
Nonuniqueness in spin-density-functional theory on lattices
(American Physical Society, 2005)
In electronic many-particle systems, the mapping between densities and spin magnetizations, {n(r),m(r)}, and potentials and magnetic fields, {v(r),B(r)}, is known to be nonunique, which has fundamental and practical ...
Dissipation through spin Coulomb drag in electronic spin dynamics
(arXiv, 2005)
Spin Coulomb drag (SCD) constitutes an intrinsic source of dissipation for spin currents in metals and semiconductors. We discuss the power loss due to SCD in potential spintronics devices and analyze in detail the associated ...
Lifetime of a quasiparticle in an electron liquid
(American Physical Society, 2005)
We calculate the inelastic lifetime of an electron quasiparticle due to Coulomb interactions in an electron liquid at low (or zero) temperature in two and three spatial dimensions. The contribution of “exchange” processes ...
Shapiro Effect as a Possible Cause of the Low-Frequency Pulsar Timing Noise in Globular Clusters
(arXiv, 2005)
A prolonged timing of millisecond pulsars has revealed low-frequency uncorrelated noise, presumably of astrophysical origin, in the pulse arrival time (PAT) residuals for some of them. In most cases, pulsars in globular ...
Pressure Raman effects and internal stress in network glasses
(American Physical Society, 2005)
Raman scattering from binary GexSe1−x glasses under hydrostatic pressure shows onset of a steady increase in the frequency of modes of corner-sharing GeSe4 tetrahedral units when the external pressure P exceeds a threshold ...
What should deflationism be when it grows up?
(Springer Verlag, 2005)
I argue that a popular brand of deflationism about truth, disquotationalism, does not adequately account for some central varieties of truth ascription. For example, given Boyle's Law is ''The product of pressure
and ...
Homology multipliers and the relation type of parameter ideals
(2005)
We study the relation type question, raised by C. Huneke, which asks whether for a complete equidimensional local ring R there exists a uniform bound for the relation type of parameter ideals. Wang gave a positive answer ...
An Extensive New Literature Concerning Low-Dose Effects of Bisphenol A Shows the Need for a New Risk Assessment
(National Institute of Environmental Health Sciences, 2005)
Bisphenol A (BPA) is the monomer used to manufacture polycarbonate plastic, the resin lining of cans, and other products, with global capacity in excess of 6.4 billion lb/year. Because the ester bonds in these BPA-based ...
The Effect of Stellar Evolution on SiC Dust Grain Sizes
(American Astronomical Society, 2005)
Stars on the asymptotic giant branch (AGB) produce dust in their circumstellar shells. The nature of the dust-forming environment is influenced by the evolution of the stars, in terms of both chemistry and density, leading ...
The Multitude of Molecular Hydrogen Knots in the Helix Nebula
(Institute of Physics, 2005)
We present Hubble Space Telescope NICMOS imaging of the H2 2.12 μm emission in five fields in the Helix Nebula ranging in radial distance from 250'' to 450'' from the central star. The images reveal arcuate structures with ...
The Nature and Origin of Molecular Knots in Planetary Nebulae
(American Institute of Physics, 2005)
Planetary Nebulae (PNe) are major contributors to the enrichment of the interstellar medium (ISM). Knots and filaments in the ionized gas images of PNe are common, if not ubiquitous. Additionally, it has been shown that ...
Decrease in Anogenital Distance among Male Infants with Prenatal Phthalate Exposure
(Environmental Health Perspectives, 2005-05)
Prenatal phthalate exposure impairs testicular function and shortens anogenital distance (AGD) in male rodents. We present data from the first study to examine AGD and other genital measurements in relation to prenatal ...
The 10 μm Feature of M-Type Stars in the Large Magellanic Cloud and the Dust Condensation Sequence
(American Astronomical Society, 2005)
We present 7-14 mm Infrared Space Observatory (ISO) spectroscopy of 12 M-type evolved stars in the Large Magellanic Cloud (LMC), in order to study the dust mineralogy and condensation process around these stars. The sample ...
On Silicon Carbide Grains as the Carrier of the 21 Micron Emission Feature in Post-Asymptotic Giant Branch Stars
(American Astronomical Society, 2005)
The mysterious 21 mm emission feature seen in 12 proto-planetary nebulae remains unidentified since its first detection in 1989. Over a dozen candidate materials have been proposed within the past decade, but none of them ...
Autism Overview
(GeneReviews, 2005-12)
This overviews Autism, including causes, evaluation Strategies, genetic counseling, management and further resources.
Of Mice and Men: Equality and Animals
(Springer Verlag, 2005)
Can material egalitarianism (requiring, for example, the significant promotion of fortune) include animals in domain of the equality requirement? The problem can be illustrated as follows: If equality of wellbeing is what ...
Why Left-Libertarianism Isn't Incoherent, Indeterminate, or Irrelevant: A Reply to Fried
(Wiley-Blackwell, 2005)
Over the past few decades, there has been increasing interest in left-libertarianism, which holds (roughly) that agents fully own themselves and that natural resources (land, minerals, air, etc.) belong to everyone in some ...
Capabilities vs. Opportunities for Well-being
(Wiley-Blackwell, 2005)
Amartya Sen and Martha Nussbaum have argued that justice is concerned, at least in part, with the distribution of capabilities (opportunities to function). Richard Arneson, G.A. Cohen, and John Roemer have argued that ...
On the Possibility of Paretian Egalitarianism
(Journal of Philosophy, 2005)
We here address the question of how, for a theory of justice, a concern for the promotion of equality can be combined with a concern for making people as well off as possible. Leximin, which requires making the worst off ...
