介绍了超重力技术的基本原理,采用解氨剂协同超重力法处理高浓度氨氮废水并进行中试研究,重点考察了超重力因子、多级处理次数、进水氨氮初始浓度、解氨剂投加量等因素对脱氮效率的影响,得出在pH为11、温度40℃、气液比1200、超重力因子460、解氨剂投加量为70 mg/L的实验条件下,单级处理脱氮率达到90.6%。相较于传统吹脱法,解氨剂-超重力法具有脱氮效率高、运行成本低、操作简单的特点,具有广阔的工业化应用前景。

We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

The collective application of shorebird tracking data to conservation
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Estimating the total mortality of seabirds following a marine heat wave
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

终末期肾病(ESRD)的重症透析患者常常出现临床或亚临床容量超负荷现象,而容量超负荷是急、慢性终末期肾病最常见的危险因素之一[1],持续的容量超载会引起水肿、血压改变、电解质紊乱和水中毒等严重后果。在2015年美国肾脏病基金会对血液透析充分性临床实践指南的建议中,指出了控制容量状态的重要性[2]。维持合适的液体容量状态是实现对心脏病科、重症医学科,

Twelve principles for successful governance of community‐based coastal marine restoration
Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...

【目的】探索合并肥胖的痛风患者临床特征及尿酸排泄特点。【方法】纳入2013年1月至2018年5月在中山大学孙逸仙纪念医院风湿免疫科住院的痛风患者228例,收集临床资料及空腹血生化指标,测定24h尿尿酸和尿肌酐并计算肾尿酸排泄指标。【结果】根据体质量指数(BMI)把患者分为肥胖组(n=44)、超重组(n=88)及非超重组(n=96),肥胖组年龄小于超重组及非超重组[43(32,57)岁比55(45,65)岁、58(45,67)岁],起病年龄小于非超重组[37(26,48)岁比48(38,59)岁 ...

目的研究肥胖儿童血尿酸水平与胰岛素抵抗的相关关系。方法选择天津市儿童医院2015年12月-2019年12月收治的335例单纯性肥胖儿童作为肥胖组,同期入选203例超重儿童作为超重组,303例体检健康儿童作为对照组。观察各组儿童体格资料,血尿酸水平,空腹血糖,胰岛素,胰岛素抵抗指数(HOMA-IR),用Pearson相关分析法分析肥胖儿童血尿酸和身体质量指数、腹围、胰岛素、HOMA-IR的相关性。结果肥胖组体重、身体质量指数、、腹围均大于超重组及对照组 ...
