HT-FED2004-56528 DEVELOPMENT AND EXPERIMENTAL VALIDATION OF AN EXERGY-BASED COMPUTATIONAL TOOL FOR DATA CENTER THERMAL MANAGEMENT

ABSTRACT The recent miniaturization of electronic devices and compaction of computer systems will soon lead to data centers with power densities of the order of 300 W/ft 2 . At these levels, traditional thermal management techniques are unlikely to suffice. To enable the dynamic smart cooling systems necessary for future data centers, an exergetic approach based on the second law of thermodynamics has recently been proposed. However, no experimental data related to this concept is currently available. This paper discusses the development and subsequent validation of an exergy-based computer model at an instrumented data center in Palo Alto, California. The study finds that when appropriately calibrated, such a computational tool can successfully predict information about local and global thermal performance that cannot be perceived intuitively from traditional design methods. Further development of the concept has promising potential for efficient data center thermal management

Lettre à la rédaction - À propos du commentaire « Santé publique clinique : exploiter le meilleur des deux mondes pour la santé comme pour le traitement des maladies »

C’est avec beaucoup d’intérêt que j’ai lu l’article « Santé publique clinique : exploiter le meilleur des deux mondes pour la santé comme pour le traitement des maladies » de Choi et ses collaborateurs. Je tiens à féliciter tous les auteurs pour le zèle dont ils ont fait preuve en menant les travaux fondateurs sur la discipline de la santé publique clinique, en tant que membres d’un groupe multidisciplinaire composé de cliniciens et de professionnels de la santé publique. J’ai pensé que vos lecteurs gagneraient à connaître certains faits historiques qui leur permettraient de mieux apprécier le travail fondamental accompli par ces auteurs

Letter to the Editor - Re: Clinical public health: harnessing the best of both worlds in sickness and health

Dear Editor, I read “Clinical public health: harnessing the best of both worlds in sickness and health” by Choi et al. with great interest and commend and congratulate all the authors for their diligence in developing the foundational work on the discipline of clinical public health by being members of the multidisciplinary group consisting of clinicians and public health professionals. I thought your readers would benefit from knowing some historical facts to appreciate the seminal work done by these authors

The Aboriginal Cultural Safety Initiative: An innovative health sciences curriculum in Ontario colleges and universities

Objectives: The Aboriginal Cultural Safety Initiative (ACSI) created at Anishnawbe Health Toronto offers an innovative curriculum to address gaps in postsecondary health sciences curricula in this area for future healthcare providers. Participants: Evaluations were collected from 1,275 students in health sciences programs in colleges and universities in Ontario. Setting: Trained volunteer Aboriginal instructors were invited as guest speakers to college and university classes in various health science disciplines. Intervention: Our instructors offered a 2- to 3-hour teaching session to health sciences students that included 3 modules on the health of Aboriginal peoples: (a) The impact of colonial and postcolonial policies on social determinants of health, (b) Contemporary health determinants and health outcomes, and (c) Aboriginal concepts of health and healing practices. Outcomes: The ACSI was able to impart the intended learning objectives to a wide array of students across health sciences disciplines, as demonstrated in the student evaluations. A significant number of students reported that their knowledge of, and interest in, Aboriginal health increased substantially when compared to their prior knowledge and interest. Conclusion: The success of this program suggests that, in the absence of Aboriginal faculty members in postsecondary health sciences departments, a committed cadre of volunteer Aboriginal instructors can improve student knowledge around issues related to Aboriginal health and can influence student attitudes through the inclusion of personal experiences in the teaching session. A lack of availability in curriculum time continues to be the largest obstacle to including content on Aboriginal cultural safety in health sciences programs
