Arsenic levels and speciation in the total suspended particles (TSPs) were quantitatively determined by high performance liquid chromatography on-line coupled with hydride generation atomic fluorescence spectrometry in Beijing, China from February 2009 to March 2011. The high TSP levels fluctuated between 0.07 and 0.79 mg m(-3), with a mean level of 0.32 ±(More)
Leaf area index (LAI) is a key variable for modeling energy and mass exchange between the land surface and the atmosphere. Inversion of physically based radiative transfer models is the most established technique for estimating LAI from remotely sensed data. This study aims to evaluate the suitability of the PROSAIL model for LAI estimation of three typical(More)
To evaluate the in-flight performance of a new hyperspectral sensor onboard an unmanned aerial vehicle (UAV-HYPER), a comprehensive field campaign was conducted over the Baotou test site in China on 3 September 2011. Several portable reference reflectance targets were deployed across the test site. The radiometric performance of the UAV-HYPER sensor was(More)
Early in the evening, a 50-year-old man presents to the emergency department with a 24-hour history of pain and swelling in his right knee. He denies recent injury or trauma. He has no prior history of joint disease or joint surgery and has no family history of arthritis. His medical history includes hypertension, for which he takes hydrochlorothiazide and(More)
Previous studies in a pig model of skin wound healing showed a coordinate expression of transforming growth factor-beta (TGF-beta) and connective tissue growth factor (CTGF), and exposure of porcine skin fibroblasts in vitro to recombinant human CTGF significantly up-regulated mRNA levels for a number of molecules. Therefore, based on recent reports that(More)
Cotton fiber is widely used as the raw materials for the textile industry. With the development in spinning technology, the improvement of cotton fiber quality is becoming more and more important. However, negative correlation between yield and fiber quality is an obstacle for cotton improvement. Molecular marker assisted selection provides a potential(More)
Lagerstroemia indica is a popular woody ornamental plant throughout the world. However, relatively little is known about the molecular processes regulating leaf color in L. indica compared with other ornamental plants. Although yellow leaf mutants from various organisms have been well characterized, L. indica yellow leaf mutant has not yet been reported. In(More)
Flowering time is an important trait for ornamental plants, and flowering regulation has thus been both a focus of and challenge to researchers. Lagerstroemia indica is an important summer flowering tree in China and has been introduced abroad as a key parent of new cultivars; no previous reports have addressed the regulation of flowering time in this(More)
Catalpa bungei is a deciduous tree native to China. It is characterized as fast growing, being highly adaptable, and having excellent wood qualities. To better understand potential mechanisms involved in adventitious root (AR) formation, we performed transcriptome analysis of softwood cuttings of C. bungei ‘Yu-1’ at three stages of AR formation using the(More)
Mn-Ce-Ti mixed-oxide catalyst prepared by the hydrothermal method was investigated for the selective catalytic reduction (SCR) of NOx with NH3 in the presence of oxygen. It was found that the environmentally benign Mn-Ce-Ti catalyst exhibited excellent NH3-SCR activity and strong resistance against H2O and SO2 with a broad operation temperature window,(More)
