Breast and prostate cancer survivor responses to group exercise and supportive group psychotherapy

This study qualitatively examined an 8 week group exercise and counseling intervention for breast and prostate cancer survivors. Groups exercised 3 days per week, 50 minutes per session, performing moderate intensity aerobic and resistance training. Groups also underwent 90 minute supportive group psychotherapy sessions once per week. Survivors discussed their experiences in focus groups post intervention. Transcripts were analyzed using interpretative phenomenological analysis. Survivors described how exercise facilitated counseling by creating mutual aid and trust, and counseling helped participants with self-identity, sexuality, and returning to normalcy. When possible, counselors and fitness professionals should create partnerships to optimally support cancer survivors

Calculations of K+, K- and phi Production in Near-Threshold Proton-Nucleus Collisions

K+, K- and \phi meson production in proton-nucleus (pA) collisions has been calculated within a BUU transport model. It is shown that the nucleon-hyperon strangeness transfer channel is essential. The role of three-body reactions has been investigated within the medium. The targetmass dependence of $\phi$ production is predicted to give important information on the in-medium properties of all three mesons.Comment: Talk presented by H.W.B. at the Budapest 2004 workshop on 'Hot and Dense Matter in Relativistic Heavy Ion Collisions', March 24-27, 2004, Budapest, Hungar

The (future) Cherenkov Telescope Array CTA

The international CTA consortium has recently entered the preparatory phase towards the construction of the next-generation Cherenkov Telescope Array CTA. This experiment will be a successor to and will benefit from the return of experience from the three major current-generation arrays H.E.S.S., MAGIC and VERITAS. It aims to significantly improve upon the sensitivity as well as the energy range of its highly successful predecessors. Construction is planned to begin by 2014, and when finished, CTA will be able to explore the highest-energy gamma-ray sky in unprecedented detail. The current status of the CTA project is presented, together with its expected performance based on Monte Carlo studies

Liquid encapsulated float zone process and apparatus

The process and apparatus for growing crystals using float zone techniques are described. A rod of crystalline materials is disposed in a cylindrical container, leaving a space between the rod and container walls. This space is filled with an encapsulant, selected to have a slightly lower melting point than the crystalline material. The rod is secured to a container end cap at one end and to a shaft at its other end. A piston slides over the rod and provides pressure to prevent loss of volatile components upon melting of the rod. Prior to melting the rod the container is first heated to melt the encapsulant, with any off-gas from this step being vented to a cavity behind the piston. The piston moves slightly forward owing to volume change upon melting of the encapsulant, and the vent passageway is closed. The container is then moved longitudinally through a heated zone to progressively melt sections of the rod as in conventional float zone processes. The float zone technique may be used in the microgravity environment of space
