Evaluation of thermal soak times

A mathematical model for the heat transfer within the electronics package of a Chaparral missile was performed. The Grashof number for this configuration was less than 2000 which indicated that the primary mode of heat transfer was conduction. The Vodicka theory for heat conduction in laminated composite media was utilized to obtain the solution for the model

Educating for Entrepreneurial Leadership: From Didacticism to Co-creation

Entrepreneurial leadership promotes organisational competitive advantage and innovation resulting in increased attention on entrepreneurial leadership development. Many higher education institutions (HEIs) claim to develop entrepreneurial leaders. However, knowledge of how to facilitate entrepreneurial leadership development is limited, the effectiveness of development practices is contestable, and current understanding of the phenomenon is mostly conceptual. We address this void by exploring educators’ perspectives of entrepreneurial leadership development and consider how the phenomenon is facilitated. We employ Interpretative Phenomenological Analysis (IPA) as our research methodology and analyse the data following IPA data analysis guidance. Findings signify the importance of placing strong emphasis on co-creating education experience with wider stakeholder involvement, thereby forming an entrepreneurial community which works collectively over the longer-term to facilitate entrepreneurial leadership development. The findings also reveal the pedagogic significance of facilitating supportive learning conditions and ‘handholding,’ a broader form of support which contradicts the established notion of ‘independent learners’ thereby challenging current ontologies around ‘student support’ when facilitating entrepreneurial leadership development

Coexistence of supravalvular aortic stenosis and osteogenesis imperfecta.

A 54 year old woman was admitted for cardiac catheterisation. She had-been attending the outpatient clinic since 1975, with regular review. She had diagnoses of type I osteogenesis imperfecta, and of supravalvular aortic stenosis. Osteogenesis imperfecta was diagnosed in early life on clinical grounds including the presence of blue sclerae and the occurrence of several bone fractures secondary to minimal trauma. A number of family members have been diagnosed with the same condition (figure 1-family pedigree). The supravalvular aortic stenosis was not diagnosed until later. She was initially referred to the cardiology clinic for further evaluation following the discovery of a systolic murmu

Polarization transfer in wide-angle Compton scattering and single-pion photoproduction from the proton

Wide-angle exclusive Compton scattering and single-pion photoproduction from the proton have been investigated via measurement of the polarization transfer from a circularly polarized photon beam to the recoil proton. The wide-angle Compton scattering polarization transfer was analyzed at an incident photon energy of 3.7 GeV at a proton scattering angle of θpcm=70°. The longitudinal transfer KLL, measured to be 0.645±0.059±0.048, where the first error is statistical and the second is systematic, has the same sign as predicted for the reaction mechanism in which the photon interacts with a single quark carrying the spin of the proton. However, the observed value is ∼3 times larger than predicted by the generalized-parton-distribution-based calculations, which indicates a significant unknown contribution to the scattering amplitude
