Dissolved oxygen dynamics in a shallow eutrophic lake: Quantify critical eco-environmental effects

Fan Zhang, Xiaohong Shi, Shengnan Zhao, Лаури Арвола et autres

Dissolved oxygen (DO) serves as a fundamental requirement for aquatic organisms and a key indicator for assessing and managing ecological health of lake ecosystems. Despite substantial research attention on lacustrine DO evolution, systematic investigations focusing on shallow eutrophic lakes remain lacking. This …

Equilibrium analysis of dissolved oxygen in Lake Wuliangsuhai during ice-covered period

Fan Zhang, Zhai Jialun

为探明中国北方浅水湖泊乌梁素海冰封期水体溶解氧平衡的内在机理，于2021年1—2月在湖心处布设了一台水质在线监测浮标，收集到包括溶解氧等在内的水质数据. 通过对溶解氧数据的小波降噪处理，结合气象资料，模拟分析了冰生长及稳定期内水体溶解氧的变化趋势，定性分析了水体溶解氧的平衡机理. 结果表明：湖泊的日均最高产氧速率为7.19 mg/(L ·d)，最低产氧速率为2.01 mg/(L ·d); 日均最高耗氧速率为7.13 mg/(L ·d)，最低耗氧速率为2.37 mg/(L ·d). 24 h的单位时间平均最高产氧速率为0.55 mg/(L ·h)，最低产氧速率为0 mg/(L ·h); 单位时间平均最高耗氧速率为0.36 mg/(L ·h)，最低耗氧速率为0.08 mg/(L ·h). 由此说明小时间尺度下溶解氧的补充消耗不均衡导致了大时间尺度下的溶解氧不平衡，进而产生了冬季湖泊的亏氧现象. 通过进一步溶解氧驱动因素与水环境因子响应关系的分析发现，浊度、水温与产氧速率呈显著负相关，叶绿素a与产氧速率和耗氧速率均呈显著正相关，表明了这些限制性水环境因子在一定程度上影响了冰下水体的溶解氧平衡.;In order to probe into the internal mechanism of dissolved oxygen (DO) equilibrium in the shallow Lake Wuliangsuhai …

Consumption of Supplementary Inulin Modulates Milk Microbiota and Metabolites in Dairy Cows with Subclinical Mastitis

Yue Wang, Xuemei Nan, Yiguang Zhao, Linshu Jiang et autres

, as well as the levels of prostaglandin A1 (PGA1), 8-iso-15-keto-PGE2, benzoic acid, etc. in milk. These data suggest that inulin intake affects the profile of microorganisms and metabolites in milk, which provides an alternative for the regulation of mastitis.

Towards in operando material process characterization over many length scales

Andrew John Allen, Fan Zhang, Lyle E. Levine, Ján Ilavský

The properties and performance of complex material systems are frequently controlled by phenomena that operate over many length-scales from sub-nanometers to millimeters. Understanding the behavior of such materials requires statistically-representative measurement of these effects on the structure and microstructure evolution across this …
