Governing with health code: Standardising China's data network systems during COVID‐19
Policy &Internet, Volume 14, Issue 3, Page 673-689, September 2022., 2022 Abstract Noting the infrastructural turn in platform studies, the article conceives China's health code system, Jian Kang Ma (JKM), deployed to manage the COVID‐19 crisis as a new social infrastructure that manifests the symbolic and material power of the Party State.

Journal of Microbiology and Biotechnology, 2019 β-Glucosidases and β-xylosidases are two categories of enzymes that could cleave out nonreducing, terminal β-D-glucosyl and β-D-xylosyl residues with release of D-glucose and Dxylose, respectively. In this paper, two functional β-glucosidase Dth3 and β-xylosidase Xln-DT from Dictyoglomus thermophilum were heterologously expressed in E.coli BL21 (DE3 ...

E o palhaço o que é? É uma mulher
Arteriais - Revista do Programa de Pós-Gradução em Artes, 2019 ResumoEste ensaio traz a fala de uma mulher que descobre em si um palhaço, mesmo atuando, há 13 anos, como palhaça. O encontro com o palhaço Uisquisito ocorreu em 2012, no grupo de teatro Palhaços Trovadores, do qual faço parte há 10 anos. A partir disso, atuar na palhaçaria com gêneros diferentes, feminino e masculino, trouxe-me reflexões não só na ...

Pensando - Revista de Filosofia, 2017 Não parece haver, ao menos num primeiro olhar, qualquer ponto de convergência entre a literatura de Lampedusa e a filosofia de Kierkegaard. Contudo, com um pouco mais de investigação, tal percepção revela-se falsa. Ambos os autores se situam no século XIX e, nesse sentido, há forte conexão entre ambos a partir de uma análise histórica, filosófica e ...

Gongye shui chuli, 2011 就零价铁处理含铀废水进行了试验研究, 考察了pH、震荡时间、静止时间、铁的投加量等因素对铀去除率的影响, 得到了最佳实验条件。通过试验对比了铁粉和废铁屑对铀废水的处理效果, 发现废铁屑比铁粉对铀的去除率更高。最后分析探讨了铁粉和废铁屑对废水中铀的去除机理, 指出零价铁对废水中铀的去除符合Langmuir吸附规律。

Gongye shui chuli, 2006 通过模拟试验，考察了自然有机物的浓度、分子质量以及溶液的pH、温度对地下水混凝除铁的影响，并研究了预氧化在混凝除铁中的作用。结果表明，有机物的浓度越高、分子质量越大，有机铁的去除率越高。当Fe2+与分子质量>10 ku的有机物络合时，用混凝除铁能取得良好的效果；当Fe2+与分子质量<4 ku的有机物络合时，采用预氧化混凝工艺能达到较好的除铁效果。在pH6.0~7.5的范围内，降低pH有利于混凝除铁。温度升高对混凝除铁有利。

Gongye shui chuli, 1982 在我国地下水除铁技术中,曝气—自然氧化和曝气—接触氧化的除铁方法被广泛采用。自然氧化除铁法是使含铁地下水与空气接触,待水中的亚铁离子氧化、水解并形成高铁沉淀物后,再将铁质沉淀物由水中分离出去。
