Parasite fauna of the grey mullet Mugil cephalus L. 1758, and its relationship with some ecological factors in Lower Kızılırmak Delta located by the Black Sea,Turkey

Parasites of the grey mullet Mugil cephalus collected from Lower K?z?l?rmak Delta in Turkey were investigated. Trichodina puytoraci, Trichodina lepsii, Ligophorus mediterraneus, Ligophorus cephali, Gyrodactylus sp., Microcotyle mugilis, Ascocotyle (Phagicola) longa, Haplosplanchnus pachysomus, Diplostomum spathaceum, Tylodelphys clavata, Posthodiplostomum sp., Neoechinorhyncus agilis and Ergasilus lizae were identified. Overall infection prevalence (%), mean intensity and mean abundance values were 99.61%, 458.10 ± 75.72 and 456.30 ± 75.44, respectively. Infection indices of parasite species in relation to season, lakes/lagoons and some physicochemical parameters of water such as temperature, salinity, dissolved oxygen and nitrate are determined and discussed. Posthodiplostomum sp. is a new parasite record for mugilids and Diplostomum spathaceum is the first record in M. cephalus, in the present study. Moreover, Ligophorus mediterraneus, Ligophorus cephali and Ergasilus lizae are new records for Turkish parasite fauna of fish and Mugil cephalus is a new host record for Neoechinorhyncus agilis in Turkey.     

基于响应面法的复合改良膨胀土无侧限抗压强度研究

为提高膨胀土的无侧限抗压强度,降低工程危害。本文在木质素改良膨胀土的研究基础上,通过单因素试验研究纤维长度、纤维掺量及木质素掺量对膨胀土抗压强度的影响规律,基于单因素试验结果,通过BBD响应面设计法进行响应面试验,建立二次回归模型,研究了双因素作用下对膨胀土无侧限抗压强度的影响。结果表明:单因素作用时,膨胀土无侧限抗压强度在各因素下均呈现先增大后减小的趋势;双因素交互作用时,木质素掺量和聚丙烯掺量二者交互作用显著性最好。由BBD响应面法得到的最优组合为:聚丙烯纤维长度为9 mm、纤维掺量为0.3%、木质素掺量为3%,该变量下平行试验组的平均抗压强度为552.48 kPa,相比于素膨胀的抗压强度提升了76.97%。可见此方案下对素膨胀的抗压强度提升效果最好。     

阴/阳离子表面活性剂混合体系性能研究

考察阴离子表面活性剂十二烷基硫酸钠（SDS）和阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）混合体系的表面张力和乳化能力,并研究无机盐对混合体系性能的影响。实验结果显示,当m（SDS）：m（CTAB）为8：2时,表面张力低至29.25mN·m^-1,表现出较强的表面活性,且无机盐有降低表面张力的作用。表面活性剂混合体系对煤油具有较好的乳化能力。     

Ostracod fauna of salt Lake Acıgöl (Acı Tuz) (Turkey)

Lakes and wetlands in Mediterranean regions are overexploited and contaminated without sufficient local governmental control. The biodiversity of Salt Lake Ac?göl (Turkey), an internationally recognized ecosystem, is presently endangered by management plans. This study aims to analyse the ostracod community to establish its ecological status as a base for future paleoecological studies using ostracods to reconstruct the recent evolution of this wetland. Samples were collected seasonally and 13 species were recorded. Multivariate classification and ordination statistical methods revealed a major difference between assemblages related to the relative abundance of species tolerant of desiccation vs. species preferring permanent waters. Cyprideis torosa, mainly found in saline, low diversity sites, is a euryhaline species regarded as an indicator of future lake conditions if inappropriate water resource management continues.
