Empirical Study on Food Safety of EU RASFF Database(欧盟RASFF食品安全实证研究) [PDF]
Shipin kexue jishu xuebao, 2014 The Rapid Alert System for Food and Feed (RASFF) database was one of the most important databases about food safety. Base on the RASFF database, the notifications between 2008and 2012were analyzed in this paper.

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 ...

Effect of chromium stress on protein profiles in saffron(铬胁迫对西红花叶片蛋白表达谱的影响)
Zhejiang Daxue xuebao. Lixue ban, 2016 铬是植物的非必需元素，对植物的生长发育具有显著的抑制作用.采用双向电泳和质谱技术，研究了铬胁迫对西红花叶片蛋白表达的影响.通过质谱技术，成功鉴定出9个在铬胁迫后下调表达的蛋白，分别为细胞分裂循环蛋白48、ATP合成酶α亚基、核酮糖二磷酸羧化酶长链（2个）、未知蛋白、核酮糖二磷酸羧化加氧酶、蛋白酶体α 亚基、铁蛋白和蛋白酶体β亚基；6个上调表达的蛋白，分别为蔗糖合酶、真核起始因子4A、α-1，4-葡聚糖蛋白合成酶、1-氨基环丙烷-1-羧酸氧化酶、异黄酮还原酶类似物IRL和未知蛋白 ...

Gongye shui chuli, 2020 制备了一种氨基改性黄麻复合材料（AF-JS），并将其应用于同时吸附去除重金属Cr（Ⅵ）和偶氮染料橙黄G（OG），利用BET、SEM、FTIR、XPS等对AF-JS吸附材料进行表征。结果表明，吸附动力学符合伪二阶动力学模型，且Langmuir方程能较好地拟合吸附等温数据，且AF-JS对Cr（Ⅵ）、OG的最大吸附容量分别可达160.09、5 137.5 mg/g。竞争吸附研究发现，OG的存在会抑制AF-JS对Cr（Ⅵ）的吸附，且抑制效果随OG浓度的递增而递增，反之亦然。AF-JS具有强稳定性和循环利用性能 ...

Gongye shui chuli, 2012 采用回收铬黄和铁氧体法对青岛某公司的高浓度含铬电镀废水进行资源化处理，并考察各因素的影响．实验结果表明，当废水初始pH=9.0，反应温度为70℃，氧化时间60 min时，废水中三价铬的氧化率达95.23%．将氧化后的废水过滤，得到铬黄母液．调节母液pH=9.0，反应温度60℃，加入硝酸铅52.6 g/L，母液中铬回收率可达100%，可获得合格的铬黄产品．采用铁氧体法进行后续处理，出水中的铬、铅均达到GB 21900-2008要求．

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 ...

Zhejiang Daxue xuebao. Lixue ban, 2012 2006年秋季采集浙江沿海主要经济鱼类6种，分析检测了鱼肉组织中重金属铜、铅、锌、镉、铬、汞、砷的质量分数.研究发现6种鱼类样品中重金属质量分数具有锌>铜>砷>铅、汞>铬>镉的分布特征.聚类分析显示，重金属质量分数综合水平为弹涂鱼>鲻鱼>白姑鱼>凤鲚>龙头鱼>菊黄东方鲀.鱼类体内重金属质量分数与海水和沉积物中的质量分数相关，但是在环境中重金属质量分数低的情况下，其自身的生理特性及摄食途径是决定性影响因子.鱼类体内的汞质量分数与水层密切相关，表现为底层>中下层>中上层的分布趋势.通过不同时空的比较 ...

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, 2004 金属铬络合染料废水中的铬Cr(Ⅲ)与偶氮类有机配体结合,呈络合状态,结构非常稳定。采用常规的中和混凝法对黑色、黄色和橙色三种铬络合物的废水进行处理,均不能有效地去除铬。研究表明,温度和酸度是影响络合态铬离子热力学稳定性的主要因素。对于黄色或橙色铬络合物,将废水进行预热以提高处理温度,或加酸酸化,都会使络合态铬离子结构破坏;而对于黑色铬络合物,其结构更为稳定,必须酸化并同时提高处理温度,才能有效地破坏黑色铬络合物的结构,游离出的铬离子极易通过投加石灰乳中和沉淀去除。因此,通过酸化、预热、中和混凝等步骤 ...
