Flow induced ultrasound scattering: experimental studies
Sound scattering by a finite width beam on a single rigid body rotation
vortex flow is detected by a linear array of transducers (both smaller than a
flow cell), and analyzed using a revised scattering theory. Both the phase and
amplitude of the scattered signal are obtained on 64 elements of the detector
array and used for the analysis of velocity and vorticity fields. Due to
averaging on many pulses the signal-to-noise ratio of the phases difference in
the scattered sound signal can be amplified drastically, and the resolution of
the method in the detection of circulation, vortex radius, vorticity, and
vortex location becomes comparable with that obtained earlier by time-reversal
mirror (TRM) method (P. Roux, J. de Rosny, M. Tanter, and M. Fink, {\sl Phys.
Rev. Lett.} {\bf 79}, 3170 (1997)). The revised scattering theory includes two
crucial steps, which allow overcoming limitations of the existing theories.
First, the Huygens construction of a far field scattering signal is carried out
from a signal obtained at any intermediate plane. Second, a beam function that
describes a finite width beam is introduced, which allows using a theory
developed for an infinite width beam for the relation between a scattering
amplitude and the vorticity structure function. Structure functions of the
velocity and vorticity fields deduced from the sound scattering signal are
compared with those obtained from simultaneous particle image velocimetry (PIV)
measurements. Good quantitative agreement is found.Comment: 14 pages, 23 figures. accepted for publication in Phys. Fluids(June

Collaborating With Colleagues To Improve Student Learning Using The Connected Mathematics Project
I am a teacher of mathematics at Millburn Middle School, Millburn, New Jersey. During my nine years at Millburn, I have taught using the Connected Mathematics Program (CMP) for seven years to eighth graders and before that, I taught CMP in it\u27s pilot stage to sixth graders.
This guide is a result of my thinking and learning during my time at Bank Street College. The guide is based on a journey through my learning as a professional developer. It is a tool which, I hope, will be of some use to other CMP leaders. It is hoped that if such a tool proves useful, that leaders will pass the torch to future leaders so they too may facilitate professional development opportunities for CMP for other new users.
This guide is in the public domain, and copies may be freely distributed among teachers and teacher leaders using CMP
Keeping company with hope and despair. Family therapists' reflections and experience of working with childhood depression
The BIOMED international outcome study on childhood depression offered a unique opportunity for the systematic treatment of children and families with major depression using systemic psychotherapy. This paper describes the experiences of clinicians working with the families referred and the theoretical and clinical models that evolved during the treatment process. The concept of 'keeping company with hope and despair' emerged as an overarching framework for thinking about the quality of the therapeutic relationship in this developing area of clinical practice. We illustrate our systemically informed interventions with case examples and discuss the role played by therapists' 'use of self' in engaging and fostering change in families gripped by depression
