Gosnay – Plaine des Chartreux, Chartreuse du Val Saint-Esprit

Date de l'opération : 1989 (SD) Inventeur(s) : Decroix P Plusieurs sondages menés au fond nord-ouest du parc de la Chartreuse (démolie à la Révolution), ont permis de retrouver des pierres ouvragées en craie, provenant peut-être du cloître, réemployées au XIXe s. dans un kiosque de jardin. Dans la cour avant du château, ont été mises au jour, à moins de 0,80 m, les fondations d’un mur de brique, large de 0,42 m à parement de pierres blanches appareillées et petits renforts de pilastres.

Cartes sur fonds d'images spatiales

La qualité géométrique, la vue synoptique sur de grandes étendues, le caractère souvent expressif des images obtenues à partir de l'espace ont provoqué l'utilisation de fonds d'images spatiales avec des surcharges chorogra phiques. On peut proposer une typologie de ces documents sur fonds d'images satellitaires dont un spécimen au 1/25 000 est présenté à partir des données SPOT

The Rural Elderly: Providers\u27 Perceptions of Barriers to Service Delivery: Providers\u27 Perceptions of Barriers to Service Delivery

A 1989 survey of the State Units on Aging (SUAs) produced five themes that seem to underlie the many barriers to the delivery of services to the rural elderly. A systematic review of these five themes led to the identification of 34 specific challenges or barriers, which were then placed under the appropriate theme. Such a schema has been outlined in order to aid social service providers, researchers, and students in making sense of the problems faced by the increasing number of rural elderly. In addition, in order to assess the relative importance of these barriers, a second survey of 172 resource persons in the field of rural aging provided data showing, by theme, which barriers are perceived to be of most importance

Advanced turbulence models for turbomachinery

Development and assessment of the single-time-scale k-epsilon turbulence model with different near-wall treatments and the multi-scale turbulence model for rotating flows are presented. These turbulence models are coded as self contained module decks that can be interfaced with a number of CFD main flow solvers. For each model, a stand-alone module deck with its own formulation, discretization scheme, solver and boundary condition implementations is presented. These satellite decks will take as input (from a main flow solver) the velocity field, grid, boundary condition specifications and will deliver turbulent quantities as output. These modules were tested as separate entities and, although many logical and programming problems were overcome, only wider use and further testing can render the modules sufficiently 'fool proof'

SU(4) symmetry in the extended proton-neutron interacting boson model: multiplets and symmetry breaking

The manifestation of $SU(4)$ symmetry within an interacting boson model including particle-like and hole-like $\pi$- and $\nu$-bosons is shown for light nuclei around the Z=N=8 shell. We also present a consistent description of the particle-hole (intruder spin or $I$ spin) multiplets in the Extended Interacting Boson Model (EIBM) and of $\pi$-$\nu$ ($F$ spin) multiplets in the IBM-2 as a breaking of this $SU(4)$ symmetry

New particle-hole symmetries and the extended interacting boson model

We describe shape coexistence and intruder many-particle-hole (mp-nh)excitations in the extended interacting boson model EIBM and EIBM-2,combining both the particle-hole and the charge degree of freedom.Besides the concept of I-spin multiplets and subsequently $SU(4)$ multiplets, we touch upon the existence of particle-hole mixed symmetry states. We furthermore describe regular and intrudermany-particle-hole excitations in one nucleus on an equal footing, creating (annihilating) particle-hole pairs using the K-spin operatorand studying possible mixing between these states. As a limiting case,we treat the coupling of two IBM-1 Hamiltonians, each decribing the regular and intruder excitations respectively, in particular lookingat the $U(5)$-$SU(3)$ dynamical symmetry coupling. We apply such coupling scheme to the Po isotopes
