Diagnosis and Treatment of Disorders of Defecation in Children
(1976-11)
This article discusses the physiology of fecal continence and disorders of defecation in childhood.
Mashhoon replies
(American Physical Society, 1992)
B. Mashhoon discusses comments made by J. Anandan on the results on the coupling of intrinsic spin to the angular velocity in a neutron interferometry.(AIP)
Generalization of Kerr spacetime
(American Physical Society, 1991)
A class of exact solutions of the Einstein-Maxwell equations is presented. It represents the exterior gravitational field of a charged rotating mass. The class contains a generalization of the charged Kerr metric involving ...
The case against teacher certification
(National Affairs, Inc., 1998)
The system by which the nation trains and licenses its public school teachers recently came under sharp attack from an organization called the National Commission on Teaching and America's Future (NCTAF). In its 1996 ...
Spectrum, volume 04, number 11 (1977)

Design criteria for formless concrete flumes (1993)
(University of Missouri--Columbia. Extension Division, 1993)
The formless concrete flume is a spillway constructed of concrete without forms. The earth is excavated to the dimensions and shape of the structure. Concrete is placed on this earth form to the required depth and floated ...

How often is a permutation an n'th power?
(1997)
We give a short argument that for any fixed n, the probability that a permutation on m letters is an n'th power is asymptotically C m^{phi(n)/n - 1}.
Bound on the group velocity of an electron in a one-dimensional periodic potential
(American Physical Society, 1995)
By using a recently derived upper bound on the allowed equilibrium current in a ring, it is proved that the magnitude of the group velocity of a Bloch electron in a one- dimensional periodic potential is always less than ...
Refractive index of waterlike fluids
(American Physical Society, 1993)
The refractive index of a waterlike fluid is calculated from a frequency- and wave-vector-dependent dielectric function. This model for the dielectric function of waterlike fluids as symmetric rotors is formulated in terms ...
Universal equilibrium currents in the quantum Hall fluid
(American Physical Society, 1995)
The equilibrium current distribution in a quantum Hall fluid that is subjected to a slowly varying confining potential is shown to generally consist of strips or channels of current, which alternate in direction, and which ...
Center of Mass and Relative Motion in Time Dependent Density Functional Theory
(American Physical Society, 1995)
It is shown that the theorem asserting separability of the center of mass motion for a system of interacting particles in a harmonic external potential is satisfied in the time dependent density functional theory, provided ...
Rigorous upper bound for the persistent current in systems with toroidal geometry
(American Physical Society, 1995)
It is shown that the absolute value of the persistent current in a system with toroidal geometry is rigorously less than or equal to eħNα/4πmr02, where N is the number of electrons, r0-2= 〈ri-2〉 is the equilibrium average ...
Engineering superfluidity in electron-hole double layers
(American Physical Society, 1998)
We show that band-structure effects are likely to prevent superfluidity in semiconductor electron-hole double-layer systems. We suggest the possibility that superfluidity could be realized by the application of uniaxial ...
Nonlocal theory of accelerated observers
(American Physical Society, 1993)
A nonlocal theory of accelerated observers is developed on the basis of the hypothesis that an electromagnetic wave can never stand completely still with respect to an observer. In the eikonal approximation, the nonlocal ...
Gradiometry and gravitomagnetic field detection
(National Aeronautics and Space Administration, Office of Management, Scientific and Technical Information Division, 1989)
Gravitomagnetism was apparently first introduced into physics about 120 years ago when major developments in electrodynamics and the strong similarity between Coulomb's law of electricity and Newton's law of gravity led ...
Neutron interferometry in a rotating frame of reference
(American Physical Society, 1988)
The physical basis for the description of phenomena by a rotating observer is investigated. A simple, yet tentative, extension of the hypothesis of locality is used to determine the interference phase shift induced by the ...
Agricultural hand signals (1993)
(University of Missouri--Columbia. Extension Division, 1993)
Voice communications are impossible in certain agricultural situations due to distance and noise. For this reason, standard Agricultural Hand Signals have been developed for farm machinery operators by the American Society ...
Constructing wire fences (1993)
(University of Missouri--Columbia. Extension Division, 1993)
This guide will provide some basic construction information to help you build a good wire fence. Good fences start with good materials.
