Revista Geografia, Literatura e Arte, 2018 A crise do conhecimento científico indica a necessidade de repensarmos o modelo uniforme de seu discurso na direção da abertura ao diálogo com outras linguagens e instâncias do saber humano, como a filosofia e, principalmente, as artes. Partindo desse pressuposto, faremos uso de alguns trechos do livro gráfico Do Inferno para analisarmos as ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Shuitu Baochi Xuebao, 2007 施用粪肥引起农田氮、磷流失的增加已引起人们广泛的关注。为了解粪肥中添加明矾可否降低农田污染物的流失,采用化学分析与田间试验相结合的方法研究了添加明矾对粪肥中水溶性养分和重金属浓度及施粪肥后农田养分、重金属流失的影响。结果表明,粪肥中添加明矾可大大降低其中的水溶性P和重金属浓度,其中水溶性P的下降幅度达79.3%。添加明矾后,粪肥施入农田形成的径流中P和重金属浓度明显低于不添加明矾的处理。但添加明矾对农田可溶性总N、NO3-N和NH4-N流失的影响不大。粪肥中添加明矾不会引起地表径流中铝浓度明显增加 ...

福州市不同种植年限茉莉花园土壤碳、氮、磷及生态化学计量比特征
Shuitu Baochi Xuebao, 2022 为了阐明种植年限对茉莉花园土壤碳(C)、氮(N)、磷(P)及其生态化学计量特征的影响, 以福州市种植年限约为3(J-3), 10(J-10), 15(J-15), 30(J-30), >40(J-40)年的茉莉花园为研究对象, 对土壤C、N、P与生态化学计量比及其影响因子进行了测定与分析。结果表明: (1)与J-3相比, 随着种植年限的增加J-10、J-30、J-40土壤容重显著下降29%, 19%和18%(P < 0.05), J-10、J-15、J-30、J-40土壤黏粒含量分别显著降低26 ...

The Role of Cdk5 in neuronal death and synaptic dysfunctions through phosphorylating FOXO1 and BAG3 [PDF]
, 2016 细胞周期蛋白依赖性激酶5（Cyclin-dependentkinase5，Cdk5）是由脯氨酸介导的丝氨酸/苏氨酸蛋白激酶，其在神经系统中发挥着重要的作用。Cdk5的活化主要靠神经系统中广泛表达的两个激活因子p35和p39。Cdk5对神经系统的正常生理功能具有重要作用去，其可通过磷酸化众多底物的丝氨酸/苏氨酸位点，在神经元的迁移分化，突触传递，轴突树突的发育过程以及神经元的存活中都发挥着重要的作用。此外，在某些病理条件下，Calpain所介导的p35切割形成p25，可以过度激活Cdk5 ...

不同施肥模式对菜-稻轮作农田土壤磷素径流损失与表观平衡的影响
Shuitu Baochi Xuebao, 2019 采用田间小区定位试验（2015—2016年）研究了自然降雨条件下农户习惯性施肥（T1）、减量施肥（T2）及优化施肥（T3）不同施肥模式对太湖流域菜—稻轮作农田土壤磷素径流流失特征和磷素表观平衡的影响。结果表明：菜—轮作农田地表径流排水主要分布于强降雨（梅雨季、台风季）集中的水稻生长季，与降雨量呈显著线性正相关关系。磷素径流流失也集中在水稻季，各处理条件下，其流失量占周年流失总量的比例达74.75%~81.46%。农户习惯性施肥模式（T1）处理条件下，蔬菜季径流总磷平均浓度（0.55 mg/L ...

Proteomic Response of Prorocentrum donghaiense to Phosphorus Depletion and Resupplement [PDF]
, 2015 磷(Phosphorus，P)是海洋浮游植物生长的限制因子，影响海洋初级生产力。东海原甲藻（Prorocentrumdonghaiense，P.donghaiense）是引起我国近海有害藻华的主要甲藻。目前有关磷对甲藻生长影响的研究已有很多报道，但主要集中在生理生态层面，对甲藻在磷限制条件下及其补充响应的分子机理方面了解较少。 本论文以P.donghaiense为研究对象，运用基于质谱的定量蛋白质组学技术—串联质谱标记（Tandemmasstag，TMT），并结合相应的转录组数据，比较研究了P ...
