Studies have shown that payments can also help lower the number of new HIV cases in Malawi and Tanzania. In Malawi, the payments permit girls to date boys their own age. These boys are less likely to be infected with the AIDS virus than older men.

Beyond legislative responsibilities, the deputations and bishops have participated in two " TEConversations" - one on racial reconciliation and one on evangelism. After hearing from practitioners and artists around these topics, the deputations were led through discussion questions asking them to make personal and diocesan commitments to deepen our work in these areas. There is one remaining TEConversation on Creation Care scheduled to take place on Wednesday, the 11th. The livestreams from these conversations and discussion guides will be available for congregational use.
The House of Deputies voted on Saturday in support of A068, to begin the process of comprehensive prayer book revision over the next triennium.
The resolution was amended multiple times from the floor of the House, adding a requirement to include Province IX (Spanish-speaking) members to the Standing Commission on Liturgy and Music, language around physical ability, availability and quality of translations, and to adhere the committee to the tenets of "The Chicago Lambeth Quadrilateral" (BCP 877-878).
The resolution now goes to the House of Bishops, where it must pass in its entirety, be voted down, or will be revised and returned to the House of Deputies.
As chair of the Committee on the Certification of Minutes, Anne delivers the report to the floor of the House of Deputies each day before the convention takes up its legislative calendar.
The House of Bishops and House of Deputies have voted to compensate the person holding the position of the President of the House of Deputies according to "director's and officer's fees" with the amount fixed by Executive Council. This vote comes after several triennia in which the House of Deputies voted to compensate and the House of Bishops voted against.
The person currently holding the position is the Rev. Gay Clark Jennings, Deputy from the Diocese of Ohio.

The Western Hills Exchange Club has changed its name to The Western Hills Community Service Club.
The original club formed in 1977 to raise money to aid local West Side organizations which fight child abuse, and to present scholarships in recognition of outstanding seniors from each of the six local West Side high schools.
Over the years, the club has donated more than $225,000 to support local charities and awarded $75,000 in scholarships. Today's difficult economy is causing the charities to be in greater need, so club members are hoping to expand their support in order to help even more of the deserving children from Cincinnati's west side.
To do this, The Western Hills Community Service Club is seeking new members. The weekly breakfast meetings are on Thursdays at 8 a.m. at the Nathanael Greene Lodge, 6394 Wesselman Road. Each week a guest speaker addresses the group and the meeting adjourns around 9 a.m.
Along with a name change, the club has a new dues structure; one cost which is geared for regular attendees and a reduced amount for those not able to attend on a weekly basis. Both individual and corporate memberships are available.
Current members agree that in addition to interesting speakers, meetings also provide a venue to discuss current events and to enjoy traditional West Side camaraderie.
Consider joining The Western Hills Community Service Club - stop by on a Thursday morning for a complimentary breakfast and to meet the membership.
To find out more about the club, contact Andy Bucher at 347-3600 or ; Tom Prince at 922-3767 or; Jim Miceli at 941-3333 or.Les anneaux tourbillonnaires (AT) sont des structures toroidales de vorticité qui se forment naturellement dans les sillages d’objets ou lors d’éjection de fluide (jet impulsif). Ces tourbillons dominent ainsi la dynamique de nombreux écoulements et sont observés dans des environnements variés. De part leur topologie, les AT ont la propriété de se propager dès lors qu’ils sont créés. Ils transportent alors le fluide qui les compose le long de leur trajectoire. Cela leur confère un pouvoir d’agitation et de mélange dans des zones éloignées de leur lieu de génération. A l’occasion de ce séminaire je présenterai des études que nous avons menées à l’IMFT sur des AT évoluant dans des milieux (i) stratifiés en densité et (ii) rhéofluidifiants viscoélastiques.
(i) De nombreux écoulements sont stratifiés en densité. Par exemple, l’océan et l’atmosphère sont stratifiés en salinité et/ou en température et donc en densité. Lorsqu’un AT pénètre une stratification, les isopycnes se déforment et de la vorticité secondaire barocline est générée. La vorticité primaire, transportée par l’AT, va alors se réorganiser avec la vorticité secondaire. Concernant la dynamique du milieu support, des ondes de gravité sont forcées par l’impact de l’AT et il résulte des interactions fortes entre les ondes générées et la structure tourbillonnaire propagative.
(ii) De nombreux écoulements mettent en jeu des fluides ayant une rhéologie non-newtonienne. On peut citer par exemple le manteau terrestre et la plupart des fluides utilisés dans l’industrie agroalimentaire. Nous nous sommes intéressés à la dynamique singulière d’un AT dans un fluide viscoélastique. En particulier, nous essayons de comprendre les mécanismes menant au « rebond » de la structure tourbillonnaire en milieu infini, i.e., sans présence de paroi solide.
Résumé: Free-surface flows are subdued to hydrodynamic instabilities, one of them observed as a coherent structure propagating at the interface between the viscous fluid flow and air named roll waves. Those instabilities develop from spatial and/or time disturbances, reaching a stationary regime downstream. Then, one important feature to predict the evolution of such a phenomenon is the length required for disturbances to travel before reaching their stationary form. The present work brings a theoretical and numerical analysis of such length required for roll waves to become stationary in a free-surface laminar flow of a Newtonian fluid. Two types of stability analysis are brought to verify flow stability and obtain parameters for wave growth rate in a Saint-Venant-like system. Then, numerical simulations are performed of the free-surface laminar transient flow of glycerin. The Navier-Stokes equations were solved using the finite volumes method, Euler schemes and PIMPLE, and the VoF technique to solve the interface. Boundary conditions were specified to obtain a steady and uniform regime given a Froude number. Then, a sinusoidal perturbation with controllable properties was applied to the inlet velocity. From the numerical results, the spatial development of the roll waves was evaluated, focusing on the establishment length as a function of the Froude number and the perturbation amplitude. The analyses performed allowed the verification of the influence of the flow’s hydraulic regime over the establishment length, and it was possible to obtain a new equation as a function of the perturbation amplitude.
The stability of soapy objects such as films, bubbles and foams has been studied widely because of the numerous applications concerning food industry, climate prediction or artistic utilization of giant bubbles.
It has been demonstrated that their stability is primarily affected by the thinning dynamics of the thin soap films. The drainage dynamics, which is the capillary or gravity driven flow in the liquid film has been widely investigated [1]. However, more recently, researchers also became interested in the influence of evaporation on this thinning dynamics [2,3].
In this seminar, I will show that, to describe bubble stability, evaporation must be taken into account as soon as the films are thin enough [4]. We will see that the bubble lifetime can be predicted by taking into account both the drainage and the evaporation to describe the thinning dynamics [2] and that this is all the more important concerning the stability of giant soap films. I will also esquisse some hypothesis concerning the influence of physical-chemistry on the film thinning and evaporation. This last result comes from a collaboration with bubbles artists, in which we developed a
