Proteomics and Expression of Immunity Related Genes Research in Fujian Oyster Under the Stress of Iron Salt and Vibrio Parahemolyticus [PDF]
牡蛎隶属于软体动物门(Mollusca)、双壳纲(Bivalvia)珍珠贝目(Pterio)。牡蛎具有很高的食用价值,现已成为中国乃至世界养殖产量最大的经济贝类。然而牡蛎养殖业面临着种种威胁,其中包括了病原体的感染。 铁是脊椎动物血红蛋白的重要组成成分,对机体免疫机制也具有重要作用。但铁对无脊椎动物免疫系统的影响鲜有研究。本论文以福建牡蛎为实验物种,以牡蛎的血淋巴和鳃为实验材料,选择铁盐为胁迫方法和诸多分析技术研究铁盐对牡蛎血淋巴和鳃产生的的影响。 本文采用3mg/L的铁盐胁迫牡蛎96小时 ...

ABSTRACT Multi‐element Prussian blue analog (PBA) nanocomposites have attracted wide attention for their superior characteristics to single‐functional nanomaterials in extensive applications of diagnosis and therapy. In this study, a novel hollow nanocomposite was designed and fabricated by embedding S2− and Ag nanoparticles into a NiCuMnFe (PBA).

目的:通过对9只来自野外和园内养大的云豹毛中锌、铜、铁、钙4种元素检测,了解云豹对这4种元素代谢特点与产生脱毛症的关系。方法:从云豹尾部的上1/3处采毛,用原子吸收光谱法检测。结果:在所检测的9只云豹中,其中3只患脱毛症的云豹毛中铜元素含量都低于4.4μg/g,其他3种元素所测结果表明与脱毛症均没有直接关系。结论:铜元素缺乏可能与云豹患脱毛症关系密切。

Preparation and Magnetic Properties of NFC Ferrite sheets with High Permeability and Low Magnetic Loss Via Aqueous Tape Casting [PDF]
近距离无线通讯(NFC)技术在最近几年发展迅速,与移动设备尤其是与手机的结合,将会极大地促进NFC技术的发展。移动设备上NFC功能的顺利实现,需要解决的硬件问题是制备一种高磁导率、低损耗的烧结铁氧体片。本论文采用固相反应法制备预烧铁氧体粉末,通过水基流延成型工艺制备铁氧体坯片,研究工艺条件、助熔剂及D离子对铁氧体片的烧结密度、微观形貌和磁学性能等的影响。通过工艺、成分和成型工艺的组合调整,制备出满足NFC功能使用的高磁导率、低磁损耗、高截止频率、厚度较薄且具有较好磁导率温度稳定性的烧结铁氧体膜片。 首先,

O artigo analisa a influência das concepções tradicionais da Psicologia nas falas de educadores e alunos sobre o fracasso escolar na atualidade. Para tanto, faz uma breve revisão da psicometria e da teoria da carência cultural como representantes da concepção ideológica que centra no indivíduo e no "ambiente" as causas do fracasso.

The Microstructure Evolution and Mechanical Properties of (FeCoCrNi)100‐x(AlCu)x High‐Entropy Alloys
ABSTRACT This study systematically investigates the effects of AlCu addition on the microstructural evolution and mechanical properties of (FeCoCrNi)100‐x(AlCu)x (x = 0, 5, 10, 15, 20; at%) high‐entropy alloys (HEAs). The results reveal that the microstructure evolves from coarse equiaxed to refined equiaxed, dendritic, and ultimately dual‐phase ...

Comumente, em referência a atletas de futebol, evoca-se uma masculinidade tradicional (BONINO, 2008), definida como modelo social hegemônico. No presente artigo, refletir-se-á sobre a chamada "área reservada masculina" (MAGUIRE & DUNNING, 1997), considerada como relevante à manutenção das estruturas patriarcais. A partir de coberturas jornalísticas
