Vegetated buffer strips were evaluated for their ability to remove waterborne Cryptosporidium parvum from surface and shallow subsurface flow during simulated rainfall rates of 15 or 40 mm/h for 4 h. Log(10) reductions for spiked C. parvum oocysts ranged from 1.0 to 3.1 per m of vegetated buffer, with buffers set at 5 to 20% slope, 85 to 99% fescue cover,(More)
Root decomposition studies have rarely considered the heterogeneity within a fine-root system. Here, we investigated fine root (< 0.5 and 0.5–2 mm in diameter) decomposition and accompanying nutrient dynamics of two temperate tree species—Betula costata Trautv and Pinus koraiensis Sieb. et Zucc. Both litterbag and intact-core techniques were used to examine(More)
OBJECTIVE To evaluate the effect of daily oral administration of decoquinate to neonatal calves experimentally challenged with various numbers of Cryptosporidium parvum oocysts. DESIGN Clinical trial. ANIMALS 75 calves. PROCEDURE Calves were purchased from a commercial dairy during a 5-week period. Calves were housed in individual hutches and fed milk(More)
Tumor biomarkers can serve as tools for early detection, diagnosis, prognosis, therapeutic target, response predicting, therapy monitoring of tumors or can be used as surrogate endpoints. Their abilities to assist various clinical decisions make them indispensable tools for current oncotherapies. Therefore, in the past decades, significant effort has been(More)
Whole-genome sequencing of wild-derived rat species can provide novel genomic resources, which may help decipher the genetics underlying complex phenotypes. As a notorious pest, reservoir of human pathogens, and colonizer, the Asian house rat, Rattus tanezumi, is successfully adapted to its habitat. However, little is known regarding genetic variation in(More)
An extensive set of column experiments was performed with freshly harvested Cryptosporidium parvum oocysts to evaluate the effects of solution chemistry, surface coatings, interactions with other suspended particles, and pore fluid velocity on the fate and transport of this widely occurring waterborne pathogen in sandy porous media. We synthesized our data(More)
Soil surface texture is an important environmental factor that influences crop productivity because of its direct effect on soil water and complex interactions with other environmental factors. Using 30-year data, an agricultural system model (DSSAT-CERES-Wheat) was calibrated and validated. After validation, the modelled yield and water use (WU) of spring(More)
This study proposes the use of marginal abatement cost curves to calculate environmental damages of agricultural systems in China's Loess Plateau. Total system costs and revenues, management characteristics and pollution attributes are imputed into a directional output distance function, which is then used to determine shadow prices and abatement cost(More)
Eu-tris(dinaphthoylmethane)-bis-(trioctylphosphine oxide) (Eu-DT) molecules encapsulated by Polystyrene and bis(trimethoxysilyl)decane nanoparticles were prepared via a modified encapsulation-reprecipitation method and show a high sensitivity to sense temperature. After surface modification with poly-L-lysine, the fluorescent nanoparticles obtained a well(More)
Transport of Cryptosporidium parvum through macroporous soils is poorly understood yet critical for assessing the risk of groundwater contamination. We developed a conceptual model of the physics of flow and transport in packed, tilted, and vegetated soilboxes during and immediately after a simulated rainfall event and applied it to 54 experiments(More)
