Towards Grammars for Cradle-to-Cradle Design
Cradle to cradle design (C2C) considers material use and reuse as integral to the composition and specification of the design. Since grammars have been used extensively to model design processes, we consider the possibilities of grammars to model C2C design. Central to our proposal is the idea that products cannot be designed in isolation, but C2C desiderata can only be achieved by explicit des...
متن کاملReducing Radiation Dose in Pediatric Diagnostic Fluoroscopy.
PURPOSE To assess radiation dose in common pediatric diagnostic fluoroscopy procedures and determine the efficacy of dose tracking and dose reduction training to reduce radiation use. METHODS Fluoroscopy time and radiation dose area product (DAP) were recorded for upper GIs (UGI), voiding cystourethrograms (VCUGs), and barium enemas (BEs) during a six-month period. The results were presented ...

SETTING The pediatric cardiac catheterization laboratory at University of Michigan Mott Children's Hospital. PATIENTS Pediatric patients with congenital heart disease. DESIGN/INTERVENTIONS We performed ...
متن کاملCradle to Cradle for End-user Computing Devices in Business
Whilst computers can and do contribute significantly to improving our use of sustainable materials and practices, computers themselves are responsible for the consumption of large amounts of such resources, contributing extensively to hazardous waste. The aim of this study is to develop a model for organisations to collect data regarding their end-user device implementation and identify areas f...
متن کاملA warning from the cradle?
LE TAUX DE MORTALITÉ INFANTILE est généralement reconnu comme un indicateur valable de la santé de la population d’un pays. Comme le signalent les Drs K.S. Joseph et Michael S. Kramer (page 535), après avoir diminué constamment pendant des années, le taux au Canada a augmenté légèrement de 1992 à 1993 et il est resté stable en 1994. Ils font état également d’une hausse marquée du taux de naissa...
