Anti‐glomerular basement membrane disease in Auckland

D. M. Taylor, M. Yehia, I. J. Simpson, H. Thein, more

Internal Medicine Journal > 42 > 6 > 672 - 676

Background: Anti‐glomerular basement membrane (GBM) antibody‐mediated disease is rare and classically presents with the syndrome of glomerulonephritis and pulmonary haemorrhage. Aim: This aim of this report was to determine the incidence, clinical features, management and outcomes of anti‐GBM disease in Auckland between 1998 and 2008. Methods: Potential patients were identified by a search for...

Measurements of Trace Gases in the Inflow of South China Sea Background Air and Outflow of Regional Pollution at Tai O, Southern China

T. Wang, H. Guo, D. R. Blake, Y. H. Kwok, more

Journal of Atmospheric Chemistry > 2005 > 52 > 3 > 295-317

We present a 16-month record of ozone (O₃), carbon monoxide (CO), total reactive nitrogen (NO_y), sulphur dioxide (SO₂), methane (CH₄), C₂ – C₈ non-methane hydrocarbons (NMHCs), C₁ – C₂ halocarbons, and dimethyl sulfide (DMS) measured at a southern China coastal site. The study aimed to establish/update seasonal profiles of chemically active trace gases and pollution tracers in subtropical Asia and...

Aircraft Measurements of Dimethyl Sulfide (DMS) Using a Whole Air Sampling Technique

I. J. Simpson, J. J. Colman, A. L. Swanson, A. R. Bandy, more

Journal of Atmospheric Chemistry > 2001 > 39 > 2 > 191-213

We present a technique for the measurement of dimethyl sulfide (DMS) from airborne and ground-based platforms, using whole air sampling followed by gas chromatography with mass spectrometer and flame ionization detection. DMS measurements that were obtained during the 1999 NASA Pacific Exploratory Mission-Tropics B showed excellent agreement with independent in-flight DMS measurements, over a wide...

The Validity of Similarity Theory in the Roughness Sublayer Above Forests

I. J. Simpson, G. W. Thurtell, H. H. Neumann, G. Den Hartog, more

Boundary-Layer Meteorology > 1998 > 87 > 1 > 69-99

Flux-gradient relationships based upon similarity theory have been reported to severely underestimate scalar fluxes in the roughness sublayer above forests, as compared to independent flux estimates (for example, eddy covariance or energy balance measurements). This paper presents the results of a unique three-month investigation into the validity of similarity theory in the roughness sublayer above...
