We describe a method of evaluating systematic errors in measurements of total column dry-air mole fractions of CO2 (XCO2 ) from space, and we illustrate the method by applying it to the v2.8 Atmospheric CO2 Observations from Space retrievals of the Greenhouse Gases Observing Satellite (ACOS-GOSAT) measurements over land. The approach exploits the lack of(More)
Pneumonia can be complicated by an empyema, progressing from an exudative effusion, to a fibrinopurulent stage with loculations, and then organized with a thick fibrinous peel. The predominant causative organisms are Streptococcus pneumoniae, Staphyloccocus aureus (including methicillin-resistant S aureus) and Streptococcus pyogenes. Recently, an increased(More)
Respiratory syncytial virus infection is the leading cause of lower respiratory tract infections in young children. Palivizumab, a respiratory syncytial virus-specific monoclonal antibody, reduces the hospitalization rate of high-risk children but it is very costly. This statement replaces three previous position statements from the Canadian Paediatric(More)
Many previous structural studies of molecular adsorbates on metal surfaces indicate that the local coordination and bonding is closely similar to that in organometallic compounds, implying that the metallic substrate has no significant influence. Here we show that such an influence is detectable for one model system, namely, the formate species, HCOO,(More)
Soon after the discovery of HCV in 1989, both serological tests for antibody detection and a genomic amplification method (reverse transcription followed by polymerase chain reaction) for HCV RNA detection were developed. With these tools in hand, investigators began studying the epidemiology, pathogenesis and natural history of HCV infection. Investigators(More)
Human well-being is dependent on goods and services provided by well-functioning ecosystems. Changes in ecosystem status and integrity can therefore impact directly and indirectly on human well-being. However, neither current measures of ecosystem health nor methods to value ecosystem services incorporate methods to assess impacts of changes in ecosystem(More)
The COMA report "The Nutrition of Elderly People" recommended that elderly people should be targeted for health education programmes in order to maintain nutritional status in this group. Recent research indicates that interventions which aim to influence nutritional behaviour are more likely to succeed if they involve target populations at all stages of(More)
How effective has the rubella vaccination program been? Before rubella immunization, the majority of Canadians contracted rubella during childhood. The rubella vaccination program has been very effective, with there being fewer than 30 cases of rubella per year reported in Canada between 1998 and 2004 [2] compared with a mean of over 15,000 cases per year(More)
Background: Inappropriate prescription of vancomycin has been shown to be associated with induction of antibiotic resistance. The objective of this study was to determine the incidence of inappropriate use of vancomycin in a tertiary care hospital in Iran. Methods: Adescriptive cross-sectional investigation was performed from September 2004 to March 2005 in(More)
