The Great Lakes constitute the largest body of surface freshwater on earth and are one of the planet's most valuable natural resources. Home to roughly 36 million people, the Great Lakes basin is a major industrial and agricultural region of North America. The Canadian portion of the basin contains one-third of the Canadian population and half of all the(More)
The environmental changes caused by climate change represent a significant challenge to human societies. One part of this challenge will be greater heat-related mortality. Populations in the northern hemisphere will experience temperature increases exceeding the global average, but whether this will increase or decrease total temperature-related mortality(More)
Resale or republication not permitted without written consent of the publisher INTRODUCTION The Southern Ocean habitat of Antarctic krill Euphausia superba (hereafter 'krill') is subject to ongoing environmental changes, such as sea ice decline (Stammerjohn et al. 2008), temperature rise ABSTRACT: Antarctic krill Euphausia superba (hereafter 'krill') occur(More)
BACKGROUND Synoptic circulation patterns (large-scale weather systems) affect ambient levels of air pollution, as well as the relationship between air pollution and human health. OBJECTIVE To investigate the air pollution-mortality relationship within weather types and seasons, and to determine which combination of atmospheric conditions may pose(More)
OBJECTIVES The objective of this study was to investigate variants of case-crossover design for assessing correlations between counts of health events over time and exposure to ambient air pollution. For illustrative purposes, daily emergency department (ED) visits for depression among females were considered. MATERIALS AND METHOD Ambient nitrogen dioxide(More)
A greenhouse experiment on broccoli (Brassica oleracea var. italica, cvs Windsor and Arcadia) was carried out in order to demonstrate that supplying nitrogen (N) to meet the nitrogen demands of plant growth stages, through N phasing, improves plant growth and yield, as compared to fertilizing at the conventional, optimal, constant N rate. Two broccoli(More)
The purpose of this study was to assess an association between ambient sulfur dioxide and the number of emergency department (ED) visits for ischemic stroke and seizure. The study used data collected in a Vancouver (Canada) hospital in the years 1999-2003. Daily ED visits diagnosed as ministroke, stroke, or seizure were investigated using the case-crossover(More)
Celery (Apium graveolens L. var Dulce) is a high value crop affected at different growth stages by a variety of nutrient disorders. Each nutrient concentration can be corrected for its dependence on concentrations of other nutrients by recognizing plant composition as a closed system whose components add up to one. New variables z i are computed as(More)
