The aim of this study was to develop a promising and competitive bioadsorbent with the abundant of source, low price and environmentally friendly characters to remove cationic dye from wastewater. The swede rape straw (Brassica napus L.) modified by tartaric acid (SRSTA) was prepared, characterized and used to remove methylene blue (MB) from aqueous(More)
The influence of periphytic biofilm on phosphorus (P) content and species between water and sediment interfaces was evaluated in a simulated experiment. Results showed that the concentration of all P species (TP, TDP, DIP, PP, and DOP) in overlying water decreased to significantly low levels (<0.05 mg L(-1)) in the presence of periphytic biofilms, while the(More)
Periphyton is ubiquitous in paddy field, but its importance in influencing the bioavailability of phosphorus (P) in paddy soil has been rarely recognized. A paddy field was simulated in a greenhouse to investigate how periphyton influences P bioavailability in paddy soil. Results showed that periphyton colonizing on paddy soil greatly reduced P content in(More)
To explain the detailed process involved in phosphorus removal by periphyton, the periphyton dominated by photoautotrophic microorganisms was employed in this study to remove inorganic phosphorus (Pi) from wastewater, and the removal kinetics and isotherms were then evaluated for the Pi removal process. Results showed that the periphyton was capable of(More)
To understand the role of ubiquitous phototrophic periphyton in aquatic ecosystem on the biogeochemical cycling of organic phosphorus, the conversion and removal kinetic characteristics of organic phosphorus (Porg) such as adenosine triphosphate (ATP) were investigated in the presence of the periphyton cultured in artificial non-point source wastewater. The(More)
The P (Pi as KH2PO4 and Po as ATP) removal processes by phototrophic periphyton were investigated by determining the removal kinetics, metal content (Ca, Mg, Al, Fe, Cu, and Zn) of the solution and P fractions (Labile-P, Fe/Al-P, Ca-P, and Res-P) within the periphyton. Results showed that the periphyton was able to remove completely both Pi and Po after 48h(More)
The impacts of biochar addition on nitrogen (N) leaching, (ammonia) NH3 volatilization from coastal saline soils are not well understood. In this soil column study, the effects of wheat straw biochar application at rates of 0.5%, 1%, 2% and 4% by weight to a coastal saline soil on N leaching, NH3 volatilization, soil pH and N retention were investigated.(More)
OBJECTIVE To develop a patient safety culture instrument for use in Chinese hospitals, we assessed the appropriateness of existing safety culture questionnaires used in the USA and Japan for Chinese respondents and identified new items and domains suitable to Chinese hospitals. DESIGN Focus group study. SETTING AND PARTICIPANTS Twenty-four physicians,(More)
Accumulating evidence has indicated that microRNAs (miRNAs or miRs) play important roles in the developing rat brain. In this study, we investigated the role of miRNAs in the brains of immature (20-80 days) rats with liquid nitrogen lesion-induced focal cortical dysplasia. miRNA microarray demonstrated that the expression of miR-139‑5p was associated with(More)
AIM The purpose of the study was to observe the ultrastructural changes of neuronal mitochondria in perihematomal brain tissue and assess the therapeutic potential of Huperzine A (HA, a mitochondrial protector) following intracerebral hemorrhage (ICH). METHODS Brain hemorrhage was induced in adult Sprague Dawley rats by injecting autologous blood into the(More)
