HYPOTHESIS As opposed to the traditional dictated report, the use of a computer-based synoptic operative report will mandate that the surgical resident have a better understanding of all facets of the procedure. DESIGN A prospective study over a 10-month period. SETTING A 636-bed community teaching hospital. PATIENTS A total of 57 consecutive patients and 60 operative procedures for breas...

The objective of this study is to introduce a new procedure to determine the impact of climate on human mortality with the use of a synoptic climatological approach. The holistic nature of synoptic categories allows for the simultaneous evaluation of numerous weather elements as they realistically appear within air masses. In addition, this approach allows for a better distinction between pollu...

To assess whether meteorological conditions modify the relationship between short-term exposure to ambient air pollution and mortality, an examination of air pollution and human mortality associations (ecologic) using hybrid spatial synoptic classification procedures was conducted. Concentrations of air pollutants and human mortality from all non-accidental and cardiorespiratory causes were exa...

29 The influence of synoptic-scale circulations on air quality is an area of increasing interest to 30 air quality management in regards to future climate change. This study presents an analysis 31 where the dominant synoptic " types " over the region of Melbourne, Australia are determined 32 and linked to regional air quality. First, a self-organising map (SOM) is used to generate a 33 time se...

5 Multiscale analysis is used to derive two sets of coupled models, each based on the same distinguished limit, to represent the interaction of the midlatitude oceanic synoptic scale — where coherent features such as jets and rings form — and the mesoscale, defined by the internal deformation scale. The synoptic scale and mesoscale overlap at low and mid latitudes, and are hence synonymous in m...

Synoptic eddy–mean flow interaction has been recognized as one of the key sources for extratropical lowfrequency variability. In this paper, the underlying dynamics of this interaction are examined from the perspective of a synoptic eddy-induced dynamic instability. To delineate this instability, a barotropic model is used that is linearized with respect to a stochastic basic flow prescribed wi...

In this paper techniques are described for the automated detection of solar Active Regions (ARs). AR detection is achieved using intensity thresholds and a region growing procedure. These procedures have been tested on full-disk solar images from the Meudon observatory for the months of April and July 2002 and compared with their manually generated synoptic maps. Comparisons were also made with...

  The site selection procedure for optical observatories housing a telescope with a sizeable aperture is described. The theory of seeing is briefly introduced and a special type of seeing monitor that is widely used for seeing measurements is discussed. The results of the meteorological studies mainly based on the wind-rose diagrams are presented. These are done for 31 preliminary selected cand...

BACKGROUND The implementation of innovations (i.e., new tools and practices) in healthcare organizations remains a significant challenge. The objective of this study was to examine the key interpersonal, organizational, and system level factors that influenced the implementation and use of synoptic reporting tools in three specific areas of cancer care. METHODS Using case study methodology, w...
