本研究旨在探讨磷脂对日本沼虾(Macrobrachium nipponense)虾青素沉积和利用的影响。磷脂水平分别设为0、20和40 g/kg,虾青素水平分别设为0和4 g/kg,根据饲料中磷脂和虾青素的添加水平设计6个组:不添加磷脂和虾青素的对照组(CON组),添加20和40 g/kg磷脂组(PL1和PL2组),添加4 g/kg虾青素组(AX组),添加20 g/kg磷脂+4 g/kg虾青素和40 g/kg磷脂+4 g/kg虾青素组(AXPL1和AXPL2组)。选择2160尾平均体重为(1.00±0.00)g的日本沼虾,随机分为6组,每组3个重复,每个重复120尾。饲养4周后,每重复随机取20尾置于氨浓度为(32.25±0.42)mg/L的水体进行胁迫试验,分别于氨胁迫前及氨胁迫24 h后采样分析。结果表明:氨胁迫后,AX、AXLP1和AXLP2组的肝胰腺中虾青素含量显著高于CON组(P0.05);氨胁迫则使肝胰腺中虾青素含量显著升高(P<0.05),T-SOD活性和T-AOC显著下降(P<0.05)。与CON组相比,PL1、PL2、AX、AXPL1和AXPL2组的肝胰腺B细胞数量均相对增多。上述结果提示,磷脂有利于日本沼虾肝胰腺对外源虾青素的沉积和对内源虾青素的调用,体内沉积的虾青素对降低氧化应激损伤具有重要作用。

本试验旨在探讨饲料中磷脂对日本沼虾(Macrobrachium nipponense)脂肪需要量的影响。选取初始体重为(0.075±0.001)g的日本沼虾为试验对象,在室内养殖缸中进行为期8周的生长试验。将鱼油和豆油等比例混合均匀,再与大豆磷脂分别按2∶1和1∶2混合,使得大豆磷脂分别占脂类混合物的33.3%(低磷脂组)和66.7%(高磷脂组)。将2种脂类混合物分别按3%(低脂肪组)、6%(中脂肪组)、9%(高脂肪组)的比例添加到饲料中,配制出6种等氮等能的试验饲料。根据试验饲料中脂类混合物添加量和大豆磷脂添加量,将6种试验饲料分别命名为L3P1、L3P2、L6P2、L6P4、L9P3、L9P6,实测试验饲料中脂肪水平分别为7%、7%、10%、10%、13%、13%。每种试验饲料投喂4缸试验虾,每缸放养150尾。结果表明:6组日本沼虾的成活率在47.8%~66.9%,以L6P4组成活率最高,其次是L3P2组,以L9P3组最低。高脂肪组的终末体重、增重率、特定生长率和成活率显著低于中、低脂肪组(P0.05),但脂类混合物添加量和大豆磷脂比例对肝胰腺T-AOC有显著的交互作用(P<0.05)。上述结果提示,日本沼虾饲料中磷脂应与脂肪保持一定的比例。根据本试验结果,饲料中脂肪水平为10%、大豆磷脂添加量为4%时对日本沼虾比较适宜。

A dynamic thermoelastic solution of a cylindrically isotropiccylindrical tube or solid cylinder with axisymmetric planedeformations is developed. Since there exist thermal boundaryconditions and trac- tions on the two surfaces of a cylindrical tube,the problem under consideration is with inhomogeneous bound- aryconditions. Therefore we introduce a special function to transformthe inhomogeneous boundary conditions to homogeneous ones for anunknown function. They by using the method of separation ofvariables, the un- known function can be expressed as themultiplication series of Bessel functions and unknown time functions.

Design and fabrication of highly efficient and stable electrocatalysts remain key challenges in green energy technologies such as low-temperature direct liquid fuel *** on in-depth theoretical calculations,here we demonstrate that surface Pd atoms with high coordination numbers(HCNs)can effectively modulate their adsorption energies for CO and OH,and thus achieve very high performance for formic acid electro-oxidation reaction(FAOR).Based on epitaxial coating Pd atomic layers onto nanoporous gold(NPG)thin membranes and a slight further decoration of Au clusters on top,the resulted core-shell structured NPG-Pd-Au electrocatalyst can demonstrate Pd intrinsic and mass activities of 8.62 mA·cm^(-2)and 27.25 A·mg^(-1)respectively at the peak potential around 0.33 V versus saturated calomel electrode toward FAOR,which are far better than those of commercial Pd/C catalysts(1.09 mA·cm^(-2)and 0.32 A·mg^(-1))tested under the same ***,the membrane electrode assemblies based on these low precious metal loading electrodes can achieve an anode Pd power efficiency over 10 W·mg^(-1)in a direct formic acid fuel cell,which is two orders of magnitude higher than that of the commercial Pd/*** results provide new inspirations for the development of revolutionary electrodes for energy technologies in a rational manner.

Design of catalyst layers(CLs)with high proton conductivity in membrane electrode assemblies(MEAs)is an important issue for proton exchange membrane fuel cells(PEMFCs).Herein,an ultrathin catalyst layer was constructed based on Pt-decorated nanoporous gold(NPG-Pt)with sub-Debye-length thickness for proton *** the absence of ionomer incorporation in the CLs,these integrated carbon-free electrodes can deliver maximum mass-specific power density of 198.21 and 25.91 kW·gPt^(-1) when serving individually as the anode and cathode,at a Pt loading of 5.6 and 22.0 pg·cm^(-2),respectively,comparable to the best reported nano-catalysts for ***-depth quantitative experimental measurements and finite-element analyses indicate that improved proton conduction plays a critical role in activation,ohmic and mass transfer polarizations.
