Exposure Assessment for Endocrine Disruptors: Some Considerations in the Design of Studies
(National Institute of Environmental Health Sciences, 2003)
In studies designed to evaluate exposure-response relationships in children's development from conception through puberty, multiple factors that affect the generation of meaningful exposure metrics must be considered. These ...
Cost and Consequences of Sedentary Living: New Battleground for an Old Enemy
(2002)
The purpose of this review is to update our earlier review by itemizing, as best we can, the costs and consequences of sedentary living, and thus provide cost reasons to fight a war against sedentary lifestyles.
Computational model of extracellular glutamate in the nucleus accumbens predicts neuroadaptations by chronic cocaine
(Elsevier, 2009-02)
Chronic cocaine administration causes instability in extracellular glutamate in the nucleus accumbens that is thought to contribute to the vulnerability to relapse. A computational framework was developed to model glutamate ...
The Rights and Duties of Childrearing
(William and Mary Bill of Rights Journal, 2003)
What rights and duties do adults have with respect to raising children? Who, for example, has the right to decide how and where a particular child will live, be educated, receive health care, and spend recreational time? ...
Sedentary death syndrome is what researchers now call America's second largest threat to public health
(2001)
Obesity has doubled, Type 2 diabetes has increased nine-fold, and heart disease remains the number one cause of death for Americans. Sedentary Death Syndrome, or "SeDS," is a growing list of health disorders that are ...
Spin, acceleration and gravity
(American Institute of Physics, 2004)
The massless field perturbations of the accelerating Minkowski and Schwarzschild spacetimes are studied. The results are extended to the propagation of the Proca field in Rindler spacetime. We examine critically the ...
Modification, Degradation, and Stability of Polymeric Surfaces Treated with Reactive Plasmas
(Journal of Polymer Science: Part A: Polymer Chemistry, 2000)
The degradation, modification, and stability of polymeric surfaces exposed to chemically reactive O2 and H2O-vapor plasmas were investigated. Specifically, the effects of these plasmas on etching rate, surface morphology, ...
Dynamics of Relativistic Flows
(arXiv, 2004)
Dynamics of relativistic outflows along the rotation axis of a Kerr black hole is investigated using a simple model that takes into account the relativistic tidal force of the central source as well as the Lorentz force ...
Gravitoelectromagnetism: A Brief Review
(arXiv, 2008)
The main theoretical aspects of gravitoelectromagnetism ("GEM") are presented. Two basic approaches to this subject are described and the role of the gravitational Larmor theorem is emphasized. Some of the consequences of ...
Standard clocks, orbital precession and the cosmological constant
(American Institute of Physics, 2003)
We discuss the influence of the cosmological constant on the gravitomagnetic clock effect and the gravitational time delay of electromagnetic rays. Moreover, we consider the relative motion of a binary system to linear ...
Identification of secondary science teachers' preconceptions related to avian influenza
(National Association for Research in Science Teaching, 2009)
How secondary science teachers understand infectious disease and disease transmission has an important impact on the public. This study analyzed the conceptions of ten secondary science teacher participants in the Maps in ...
Tidal Dynamics of Relativistic Flows Near Black Holes
(arXiv, 2003)
We point out novel consequences of general relativity involving tidal dynamics of ultrarelativistic relative motion. Specifically, we use the generalized Jacobi equation and its extension to study the force-free dynamics ...
A Gravitational Mechanism for the Acceleration of Ultrarelativistic Particles
(arXiv, 2005)
Imagine a swarm of free particles near a point P outside a gravitating mass M and a free reference particle at P that is on a radial escape trajectory away from M. Relative to this reference particle and in a Fermi normal ...
Structure and phase transitions of monolayers of intermediate-length n-alkanes on graphite studied by neutron diffraction and molecular dynamics simulation
(American Institute of Physics, 2009)
We present evidence from neutron diffraction measurements and molecular dynamics (MD) simulations of three different monolayer phases of the intermediate-length alkanes tetracosane (n-C24H50 denoted as C24) and dotriacontane ...
Nanoscale observation of delayering in alkane films
(Institute of Physics, 2007)
Tapping-mode Atomic Force Microscopy and synchrotron X-ray scattering measurements on dotriacontane (n-C32H66 or C32) films adsorbed on SiO2-coated Si(100) wafers reveal a narrow temperature range near the bulk C32 melting ...
The Dust Ring of Luminous Blue Variable Candidate HD 168625: Infrared Observations and Model Calculations
(Institute of Physics, 2003)
We present a 2.218 lm image from the Hubble Space Telescope/Near Infrared Camera and Multi-Object Spectrometer (NICMOS) and a 55 lm image from ISOPHOT of the dust ring surrounding the luminous blue variable (LBV) candidate ...
Exposure to a Low Dose of Bisphenol A during Fetal Life or in Adulthood Alters Maternal Behavior in Mice
(National Institute of Environmental Health SciencesEnvironmental Health Perspectives, 2002)
Maternal behavior in mammals is the result of a complex interaction between the lactating dam
and her developing offspring. Slight perturbations of any of the components of the mother-infant interaction may result in ...
Molecular Hydrogen in the Ring Nebula: Clumpy Photodissociation Regions
(University of Chicago Press, 2003)
We present a 0 .65 resolution H2 1-0 S(1) 2.122 mm image of the Ring Nebula (NGC 6720),
which was taken with the Near Infrared Imager at the WIYN 3.5 m telescope on Kitt Peak. The high resolution of the H2 observation is ...
Circular holonomy and clock effects in stationary axisymmetric spacetimes
(American Institute of Physics, 2001)
Stationary axisymmetric spacetimes containing a pair of oppositely rotating periodically intersecting circular geodesics allow us to study the various so-called 'clock effects' by comparing either observer or geodesic ...
The generalized Jacobi equation
(American Institute of Physics, 2002)
The Jacobi equation in pseudo-Riemannian geometry determines the linearized geodesic flow. The linearization ignores the relative velocity of the geodesics. The generalized Jacobi equation takes the relative velocity into ...
