[Spatial-temporal Distribution of Suspended Solids and Its Sedimentation Flux and Nutrients Effects in Xin'anjiang Reservoir, China].

To analyze the spatial-temporal distribution and sedimentation characteristics of suspended solids in reservoirs, high-frequency monitoring of a sediment trap and buoy, combined with three-dimensional water sampling, was conducted and analyzed in Xin'anjiang Reservoir for a year. The results showed that the turbidity data of the buoy has significant correlation with rainfall, inflow, and suspended solids (SS), particularly for SS (<0.01, =0.

[Applicability of Bioavailable Phosphorus in Sediments to Indicating Trophic Levels of Lakes and Reservoirs].

Twelve lakes and reservoirs with different water depths and different water residence times were studied to identify the applicability of bioavailable phosphorus of sediments in indicating trophic levels. Water and sediment samples were collected in these 12 lakes and reservoirs to analyze the relationship of nutrient levels between the sediment and the water column. Sodium hydroxide extracted phosphorus (NaOH-P) determined using the SMT classification method is defined as the bioavailable phosphorus of sediment.

[Occurrence and Influencing Factors of Odorous Compounds in Reservoirs Used as Drinking Water Resources in Jiangsu Province].

In order to recognize the risk of odorous compounds and its driving mechanisms in water source reservoirs, the water quality, plankton, and odorous compounds of 17 provincial water source reservoirs in Jiangsu Province were investigated during a high-risk period of odorous compounds. A high eutrophication status, such as high algal biomass and low transparency, were widely observed in our study reservoirs. In addition, 2-methylisoborneol (MIB) exceeded the standard in some water layers of one-third of the reservoirs, of which the average concentration was (13.

Electroacupuncture and moxibustion promote regeneration of injured sciatic nerve through Schwann cell proliferation and nerve growth factor secretion.

Using electroacupuncture and moxibustion to treat peripheral nerve injury is highly efficient with low side effects. However, the electroacupuncture- and moxibustion-based mechanisms underlying nerve repair are still unclear. Here, in vivo and in vitro experiments uncovered one mechanism through which electroacupuncture and moxibustion affect regeneration after peripheral nerve injury.

[Synthesis of azobenzol compound and analytical application in a new catalytic spectrophotometry system].

Analysis of the indicator synthesis was studied by catalytic spectrophotometry, and the reducing decolorization that the copper(II) catalyzed the ration between ascorbic acid and 3-methyl-4-amino-4'-nitro azobenzol was discussed. Reaction condition was optimized and a highly selective determination of trace copper(II) was established. The detection limit was 0.
