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 ...

Evaluating the use of taxonomy in the IUCN Red List
Conservation Biology, EarlyView.Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Conservation Biology, EarlyView.Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

Shuitu Baochi Xuebao, 2020 为了确定保护性耕作措施对北京周边农田土壤风蚀及颗粒物释放的影响，通过风洞模拟试验，对比不同风速和不同覆盖度下农田土壤风蚀速率及TSP、PM10、PM2.5、PM1的释放差异，并分析了4种细颗粒物在风蚀物中的占比。结果表明：（1）当风速16 m/s时，秸秆覆盖度需达到40%才能达到理想的防风蚀效果。（2）TSP、PM10、PM2.5、PM1 4种细颗粒物的释放量与风速呈正指数函数关系，与覆盖度呈负指数函数关系；随风速的增加，4种细颗粒物的释放能力为A > B1 > B2 > B3 > B4 > B5 ...

Conservation Biology, EarlyView.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 ...

Shuitu Baochi Xuebao, 2022 为明确风水交错侵蚀中风力和水力侵蚀的相互影响,针对风向和径流方向相反(迎风坡)的交错侵蚀,采用人工模拟降雨与风洞试验研究前期风蚀对后继水蚀的影响。结果表明:(1)受前期风蚀影响,后继水蚀产流时间均较仅水蚀提前,径流强度较仅水蚀增大。(2)前期风蚀加剧后继水蚀却未改变其变化趋势。无论是否有前期风蚀影响,后继水蚀速率随降雨历时增加均逐渐增大而后趋于平稳;但当前期风蚀的风速较大时(12,15 m/s),后继水蚀速率较仅水蚀增大最显著,其侵蚀速率高达仅水蚀速率的4.6倍。(3)受前期风蚀影响 ...
