Au cours des deux dernières décennies, la demande d’aide alimentaire auprès des organismes caritatifs n’a cessé d’augmenter et un important système de banques alimentaires s’est mis en place au Canada. Pour évaluer la précarité et la vulnérabilité alimentaires d’un sous-groupe d’usagers des banques alimentaires, on a interviewé un échantillon de 153 femmes dans des familles faisant appel aux programmes d’aide alimentaire d’urgence dans la région métropolitaine de Toronto. Quatre-vingt dix pour cent d’entre elles ont déclaré disposer d’un revenu représentant moins de deux tiers du revenu correspondant au « seuil de pauvreté », et 94 % d’entre elles ont déclaré avoir craint manquer de nourriture au cours des 12 mois précédents. Soixante dix pour cent ont déclaré un certain manque absolu de nourriture malgré leur recours aux banques alimentaires. Les résultats soulignent les capacités limitées des programmes d’aide alimentaire caritatifs pour répondre aux problèmes d’insécurité alimentaire vécue dans les foyers souffrant de pauvreté extrême et chronique. publisher-imprint-name Springer volume-issue-count 6 issue-article-count 16 issue-toc-levels 0 issue-copyright-holder The Canadian Public Health Association issue-copyright-year 1999 article-contains-esm No article-numbering-style Unnumbered article-registration-date-year 1999 article-registration-date-month 11 article-registration-date-day 24 article-toc-levels 0 toc-levels 0 volume-type Regular journal-product ArchiveJournal numbering-style Unnumbered article-grants-type Regular metadata-grant OpenAccess abstract-grant OpenAccess bodypdf-grant Restricted bodyhtml-grant Restricted bibliography-grant Restricted esm-grant OpenAccess online-first false pdf-file-reference BodyRef/PDF/41997_1999_Article_BF03404112.pdf target-type OnlinePDF issue-type Regular article-type OriginalPaper journal-subject-primary Medicine & Public Health journal-subject-secondary Public Health open-access false This research was funded by Health Canada through the National Health Research and Development Program (NHRDP), NHRDP Project No. 6606-5609-201.

N2 - A new zoning method called “virtual zones” has been developed for application to an unsteady finite difference Navier-Stokes code. The virtual zoning method simplifies the zoning and gridding of complex configurations for use with patched multi-zone flow codes. An existing interpolation method has been extensively modified to bring the run time for the interpolation procedure down to the same level as for the flow solver. Unsteady Navier-Stokes computations have been performed for transonic flow over a clipped delta wing with an oscillating control surface. The computed unsteady pressure and response characteristics of the control-surface motion compare well with experimental data.
