Our previous work demonstrated formation of highly insoluble and strongly light-absorbing organic particles in reactions between catechol or guaiacol with Fe( iii ) under pH = 3 conditions characteristic aerosol liquid water.
We used a 1-D cloud parcel model to assess the impact of biomassburning aerosol on cloud properties in the Amazon Basin and to identify the physical and chemical properties of the aerosol that influence droplet growth. Cloud condensation nuclei (CCN) measurements were performed between 0.15 and 1.5% supersaturation at ground-based sites in the states of Amazonas and Rondônia, Brazil, during sev...
UNLABELLED Aristolochic acid I (AAI) is a plant drug found in Aristolochia species that causes aristolochic acid nephropathy, Balkan endemic nephropathy and their associated urothelial malignancies. AAI is activated via nitroreduction producing genotoxic N-hydroxyaristolactam, which forms DNA adducts. The major enzymes responsible for the reductive bioactivation of AAI are NAD(P)H quinone oxi...
In this study we examine the performance of 31 global model radiative transfer schemes in cloudfree conditions with prescribed gaseous absorbers and no aerosols (Rayleigh atmosphere), with prescribed scatteringonly aerosols, and with more absorbing aerosols. Results are compared to benchmark results from high-resolution, multiangular line-by-line radiation models. For purely scattering aerosols...
Visible-light-absorbing carbonaceous aerosols within the boundary layer affect radiance and polarization states of radiation at top atmosphere. Remote sensing from suborbital satellite-based platforms utilizes these signals to retrieve key properties aerosols. Recent retrieval algorithms have shown a progressive trend toward including multi-angular multi-spectral polarimetric measurements produ...
In March 2006, a multiagency field campaign was undertaken in Mexico City called the Megacities Initiative: Local and Global Research Observations (MILAGRO). Two of the five field components of the MILAGRO study focused a major part of their efforts on atmospheric particulate emissions from the Mexico City basin and their effects on radiative balance as a function of time, location and processi...
This study aims to develop and validate a strength-based instrument for assessing the academic advising needs of university students in Hong Kong using Appreciative Advising Inventory (AAI) as blueprint. We reviewed content validity cultural relevance AAI developed 37-item Version (AAI-HK). conducted Rasch analysis principal component analysis. The AAI-HK has four stable reliable factors (socia...
Exposure to aristolochic acid I (AAI) can lead to aristolochic acid nephropathy (AAN), Balkan endemic nephropathy (BEN) and urothelial cancer. The induction of hepatic CYP1A, especially CYP1A2, was considered to detoxify AAI so as to reduce its nephrotoxicity. We previously found that baicalin had the strong ability to induce CYP1A2 expression; therefore in this study, we examined the effects o...
[1] The Moderate Resolution Imaging Spectroradiometer (MODIS) currently provides the most extensive aerosol retrievals on a global basis, but validation is limited to a small number of ground stations. This study presents a comprehensive evaluation of Collection 4 and 5 MODIS aerosol products using ground measurements from the Chinese Sun Hazemeter Network (CSHNET). The Collection 5 product use...
