Investigation and Development of an Asset Capability Business ProcessMulligan, Andrew Barton January 2013 (has links)
A project was undertaken as part of the University of Canterbury Master of Engineering Management Programme that addressed the issue of how Orion New Zealand Limited can improve their asset capability information and associated business processes. An audit approach was used to review data quality and availability, information systems integration, management processes and information flows that would support the development and implementation of branch and cyclic/dynamic ratings. The project found the existing Orion environment does not fully support asset capability information management. Information systems are well integrated, complex and hold substantial, but incomplete asset capability data. Asset policies, plans and documentation are comprehensive, but do not specifically reference asset capability information. The project concluded implementing a full asset capability information management regime was not considered feasible at the time. However, there was merit in improving existing data acquisition, system integration and business processes to enable the development of asset branch and cyclic/dynamic ratings in order to enhance network utilisation. Recommendations focus on establishing a standard for asset capability information, improving information system solutions through further integration and refining existing business processes through incremental changes. Field-‐testing, computer modeling and load flow analysis on the effects of cyclic/dynamic ratings were recommended to confirm the merits of full implementation.

Épidémiologie des infections à Clostridium difficile chez les patients hospitalisés dans un centre hospitalo-universitaire / Clostridium difficile infection in patients hospitalized in a large tertiary hospitalKhanafer, Nagham 23 September 2013 (has links)
Clostridium difficile est responsable de 15 à 25% des cas de diarrhées post-antibiotiques (ATB) et de plus de 95% des cas de colite pseudomembraneuse. Depuis 2003 et suite à l'émergence du clone 027, les ICD sont devenues plus fréquentes et plus sévères. Compte tenu des conséquences, il a été décidé d'explorer en détail et prospectivement cette maladie au Groupement Hospitalier Edouard Herriot L'inclusion des patients a débuté fin février 2011 et devrait s'arrêter fin février 2014. Dans une méta-analyse, nous avons montré que l'ICD communautaire est associée à l'exposition aux mêmes ATB qu'une ICD nosocomiale. Une analyse de la littérature, en utilisant la grille ORION comme outil, nous a permis de synthétiser les connaissances sur la prévention et le contrôle d'ICD en milieu hospitalier. Par la suite sur la base d'une étude rétrospective, le sexe, la CRP et l'exposition aux fluoroquinolones ont été identifiés comme associés à une ICD sévère chez les patients hospitalisés en réanimation. Entre 2011 et 2013, 430 patients ont été inclus dans notre cohorte. L'analyse des données de la prise en charge thérapeutique de 118 cas d'ICD a montré un niveau insuffisant de la connaissance des recommandations actuelles concernant le traitement de cette infection. L'analyse pronostique a montré un taux de mortalité de 19,5% dans les 30 jours qui suivent le diagnostic. L'ICD était indiquée comme une cause principale ou contributive de décès dans quinze cas (65,7% des décédés). Les analyses multivariées ont montré que les facteurs associés au décès sont différents entre les patients avec une ICD et les patients présentant une diarrhée non liée au Clostridium difficile / Clostridium difficile is responsible for almost all cases of pseudomembranous colitis and for 15%-25% of cases of post-antibiotic (ATB) diarrhea. Since 2003 and the emergence of 027 strain, CDI epidemiology is changing, with evidence of rising incidence and severity. In response to the alarming situation we decided to conduct a prospective study at Eduard Herriot Hospital to explore in details this infection. Patient’s inclusion has started in February 2011 and will end in February 2014. In a meta-analysis we found that the risk profiles for antimicrobial classes as risk factors for community-acquired CDI are similar to those described for nosocomial CDI. We used the ORION statement (Outbreak Reports and Intervention Studies Of Nosocomial infection) to synthesize knowledge of interventions to reduce and to control CDI in hospitals. Then in a retrospective study, we found that male gender, rising serum C-reactive protein level, and previous exposure to fluoroquinolones were independently associated with severe CDI in ICU. Between 2011 and 2013, 430 patients were included in our prospective cohort study. Data analysis of 118 cases of CDI showed an inefficient knowledge of current recommendations of CDI treatment. The crude mortality rate within 30 days after CDI diagnosis was 19.5%, with 15 deaths (65.7% of deceased patients) related to CDI. In a multivariate cox regression model, gender, serum albumin, antidiarrheal medications, cephalosporins, peritonitis and septic shock were independently associated with mortality in CDI patients. When diarrhea was not related to C. difficile, mortality was rather associated with cancer and high WBC level

The ALMA View of the OMC1 Explosion in OrionBally, John, Ginsburg, Adam, Arce, Hector, Eisner, Josh, Youngblood, Allison, Zapata, Luis, Zinnecker, Hans 03 March 2017 (has links)
Most massive stars form in dense clusters where gravitational interactions with other. stars may be common. The two nearest forming massive stars, the BN object and Source I, located behind the Orion Nebula, were ejected with velocities of similar to 29 and similar to 13 km s(-1) about 500 years ago by such interactions. This event generated an explosion in the gas. New ALMA observations show in unprecedented detail, a roughly spherically symmetric distribution of over a hundred (CO)-C-12 J = 2-1 streamers with velocities extending from V-LSR = -150 to +145 km s(-1) The streamer radial velocities increase (or decrease) linearly with projected distance from the explosion center, forming a '' Hubble Flow '' confined to within 50 ''. of the explosion center. They point toward the high proper-motion, shock-excited H-2 and [Fe II] '' fingertips '' and lower-velocity CO in the H-2 wakes comprising Orion's '' fingers.'' In some directions, the H-2 '' fingers '' extend more than a factor of two farther from the ejection center than the CO streamers. Such deviations from spherical symmetry may be caused by ejecta running into dense gas or the dynamics of the N-body interaction that ejected the stars and produced the explosion. This similar to 10(48) erg event may have been powered by the release of gravitational potential energy associated with the formation of a compact binary or a protostellar merger. Orion may be the prototype for a new class of stellar explosiozn responsible for luminous infrared transients in nearby galaxies.

PROTOPLANETARY DISKS IN THE ORION OMC1 REGION IMAGED WITH ALMAEisner, J. A., Bally, J. M., Ginsburg, A., Sheehan, P. D. 14 July 2016 (has links)
We present ALMA observations of the Orion Nebula that cover the OMC1 outflow region. Our focus in this paper is on compact emission from protoplanetary disks. We mosaicked a field containing similar to 600 near-IR-identified young stars, around which we can search for sub-millimeter emission tracing dusty disks. Approximately 100 sources are known proplyds identified with the Hubble Space Telescope. We detect continuum emission at 1 mm wavelengths toward similar to 20% of the proplyd sample, and similar to 8% of the larger sample of near-IR objects. The noise in our maps allows 4 sigma detection of objects brighter than similar to 1.5 mJy, corresponding to protoplanetary disk masses larger than 1.5 M-J (using standard assumptions about dust opacities and gas-to-dust ratios). None of these disks are detected in contemporaneous CO(2-1) or (CO)-O-18(2-1) observations, suggesting that the gas-to-dust ratios may be substantially smaller than the canonical value of 100. Furthermore, since dust grains may already be sequestered in large bodies in Orion Nebula cluster (ONC) disks, the inferred masses of disk solids may be underestimated. Our results suggest that the distribution of disk masses in this region is compatible with the detection rate of massive planets around M dwarfs, which are the dominant stellar constituent in the ONC.
