Colored dissolved organic matter (CDOM) is an important part of aquatic ecosystems and plays a key role in the biogeochemical cycle. In this study, CDOM absorption spectrum curves water quality parameters from 30 sampling sites wetlands Poyang Lake, Jiangxi Province, China, were collected October 2016. The optical characteristics spatial distribution CDOM, correlation between coefficient at wav...

In earlier studies, it was demonstrated that the sensitivity of absorbance detection in liquid chromatography (LC) can be improved significantly by using cavity ring-down spectroscopy (CRDS). Thus far, CRDS experiments have been performed using visible laser light at fixed standard wavelengths, such as 532 nm. However, since by far most compounds of analytical interest absorb in the ultraviolet...

Black light supercontinuum generation is demonstrated as a result of picosecond pumping a solid-core photonic crystal fiber at 355~nm through the combined effects of intermodal four-wave mixing and cascaded Raman scattering. OCIS codes: 190.4370, 190.5650, 190.4005. The study of supercontinuum (SC) generation in photonic crystal fibers (PCF) continues to be an area of active research, motivated...

Biological characteristics of two strains of the entomopathogenic nematode, Heterorhabditis floridensis (332 isolated in Florida and K22 isolated in Georgia) were described. The identity of the nematode's symbiotic bacteria was elucidated and found to be Photorhabdus luminescens subsp. luminescens. Beneficial traits pertinent to biocontrol (environmental tolerance and virulence) were characteri...
