Effects of Solar UV Radiation on Morphology and Photosynthesis of Filamentous Cyanobacterium Arthrospira platensis
ABSTRACT To study the impact of solar UV radiation (UVR) (280 to 400 nm) on the filamentous cyanobacterium Arthrospira (Spirulina) platensis, we examined the morphological changes and photosyntheticExpand

Utilization of solar UV radiation by coastal phytoplankton assemblages off SE China when exposed to fast mixing
During May 2002 we carried out studies with tropical phytoplankton assemblages from coastal waters off SE China to assess the combined effects of solar UV radiation (UVR, 280 to 400 nm) and mixingExpand

Synthesis of uridine phosphoramidite analogs: reagents for site-specific incorporation of photoreactive sites into RNA sequences.
The synthesis of three new photoactive RNA phosphoramidites, 5-bromouridine, 5-iodouridine, and O4-triazolouridine, is reported. The 5' OH of bromouridine and iodouridine were protected asExpand

Comparison on mechanical properties and microstructure of a C–Mn–Si steel treated by quenching and partitioning (Q&P) and quenching and tempering (Q&T) processes
Abstract A steel containing Fe–0.20C–1.57Mn–1.55Si–0.0029P–0.0018S (wt%) was treated by quenching and partitioning (Q&P) and quenching and tempering (Q&T) process. The resulted mechanical propertiesExpand
