1First record of marine crab,Eucrate alcocki Serène,in Serène and Lohavanijaya,1973 (Crustacea,Decapoda,Brachyura,Euryplacidae) from India显示文摘This paper reports the occurrence of a marine brachyuran crab species Eucrate alcocki Serène,in Serène et al.,1973,of the family Euryplacidae Stimpson,1871,for first time from India,based on a male specimen from Parangipettai fish landing centre in Bay of Bengal,Southeast Coast of India.Although morphologically corresponding with what is currently defined as E.alcocki,the color pattern of the carapace of the present specimen is rather different from that of the Chinese material-only the anterior fifth of the carapace is marked with scattered red spots,the rest of the surface is yellowish,with four unusually shaped red blotches which almost look like Sanskrit characters.M.RAJKUMAR K.P.KUMARAGURU VASAGAM 李新正 孙军 2009Chinese Journal of Oceanology and Limnology2009,27,4:2
2A review of Epipenaeon ingens Nobili, 1906 (Isopoda: Bopyridae) host species and documentation of a new host, Metapenaeopsis stridulans (Alcock, 1905) (Decapoda: Penaeidae)显示文摘We collected 3 596 Metapenaeopsis stridulans (Decapoda: Penaeidae) from the southeast coast of India between January and December 2007. Sixty three specimens (43 females and 18 males) were parasitized by the bopyrid isopod Epipenaeon ingens (Isopoda: Bopyridae). This is the first report of the occurrence of E. ingens in this host; therefore, it was considered as a new host record. The highest level of infestation (3.2%) occurred in October 2007, coincident with observations of gravid females (9). The total prevalence and presence of gravid females were 17.46% and 28%, respectively. Infestation caused a characteristic bulge of the branchial chamber, growth retardation, and degeneration of the sex organs, but had no effect on the host weight.M.RAJKUMAR S.MANOKARAN 孙军 J.P.TRILLES 2011Chinese Journal of Oceanology and Limnology2011,29,1:0
3Occurrence of double parasitism on black-barred halfbeak fish from the southeast coast of India显示文摘A double parasitism(isopod Cymothoidae and copepod Pennellidae) on black-barred halfbeak fish,Hemiramphus far,was recorded from Pazhayar coastal waters(southeast coast of India) during September 2008.This is the first report from this region and the infection is discussed in relation to environmental and biological parameters.A.GOPALAKRISHNAN M.RAJKUMAR 孙军 J.P.TRILLES 2010Chinese Journal of Oceanology and Limnology2010,28,4:0
4通过使用耦合换热模型模拟通过柴油机活塞的热损失和研究热障涂层对换热损失的影响规律显示文摘壁面边界产生的热损失对内燃机的整体性能和效率起主要作用。通常恒温壁边界条件用于典型的发动机模拟开发[1-3]。由于涉及到发动机燃烧的复杂性,这些边界条件不能从试验中精确估计。因此,在发动机模拟中,这些边界条件引起了很多的不确定性和不定参数。在非稳态发动机计算流体动力学(CFD)模拟中通过实体壁的热传递过程建模,开发出更高精度的发动机模型。这些发动机模型可用于研究热损失对发动机效率的影响,并用于研究减少热损失的新设计方法。利用单缸柴油机与连接到流体域的固体活塞一起建模,通过耦合热传递(CHT)建模技术,模拟Navistar柴油机的完整循环热损失,然后根据嵌入在活塞表面内的热电偶的试验数据验证该CFD模型。来自模型的总体预测与试验观察紧密地匹配。经过验证的发动机模型被进一步用于探索热障涂层(TBC)应用于活塞燃烧室上的优点。TBC涂层产生的效果在热传递模型建模中被设定为热阻。全周期3D发动机模拟提供了对热损失的定量分析,从而提高了使用TBC涂层的计算效率,为往复式发动机的CHT建模建立了可靠的框架。P.Kundu R.Scarcelli S.Som A.Ickes Y.Wang J.Kiedaisch M.Rajkumar 闫红梅(译) 陈建伟(译) 2018汽车与新动力2018,1,4:0
