【裁判要旨】船舶建造合同履行过程中,船厂以其享有留置权为由拒绝交付船舶,使合同履行陷入僵局的现象较为常见。本案双方当事人“先交船再结算”的约定排除了船舶留置权的适用,但船厂仍以对方未全额支付船舶建造款为由拒绝交付船舶证... 详细信息

【裁判要旨】船舶建造合同履行过程中,船厂以其享有留置权为由拒绝交付船舶,使合同履行陷入僵局的现象较为常见。本案双方当事人“先交船再结算”的约定排除了船舶留置权的适用,但船厂仍以对方未全额支付船舶建造款为由拒绝交付船舶证书、拒绝配合办理船舶登记,其行为构成违约。在船东提供相应担保后,法院依法作出了诉前海事强制令,责令船厂交付船舶检验证书并协助办理船舶登记手续,及时纠正船厂的违约行为,均衡双方当事人的利益,打破合同履行僵局,凸显出海事特别程序短、平、快的程序价值。

【目的】为了明确对免疫检查点阻断(ICB)治疗应答反应较差的非小细胞肺癌(NSCLC)患者与肿瘤组织白细胞介素(ILs)表达水平之间的潜在关联,探讨其在NSCLC患者肿瘤中的表达差异及其对患者ICB疗效和预后的影响。【方法】从既往研究数据中回顾性收集确诊为NSCLC且经过ICB治疗的61例患者,取得其ICB治疗前的肿瘤组织转录组测序及生存相关的数据,通过生物信息学方法,筛选出显著影响患者ICB治疗疗效与预后的ILs,以无进展生存期(PFS)评价疗效和总生存期(OS)评价患者的预后,使用Kaplan-Meier生存曲线和ROC曲线分析ILs对NSCLC患者ICB疗效和预后的预测作用及效能。【结果】通过单因素Cox回归分析,筛选出9个与NSCLC患者OS相关的ILs(P0.05),但当两者与IL-17D的表达模式联合时,发现上述3种ILs均为高表达的NSCLC患者,中位PFS与OS分别缩短至2.2个月(P=0.003)和3.0个月(P<0.001),ROC曲线表明其预测效能得到提升[AUCPFS=0.748,95%CI(0.615,0.880),P=0.007;AUCOS=0.703,95%CI(0.573,0.833),P=0.007]。【结论】IL-11、IL-17D和IL-36A高表达提示NSCLC患者疾病进展的风险较高,与患者不良的PFS和OS相关,可能为NSCLC的ICB辅助治疗提供新的策略。

This paper studied an architecture model of turbidite channel systems based on the shallow- layer high resolution 3D seismic information in the deepwater area in the Niger Delta continental slope, West Africa as a prototype model. Different types of channel systems were identified and the corresponding architecture models were established. The controlling factors, evaluation criteria and spatial distribution of different channel systems were analyzed. This study shows that turbidite channel systems of West Africa could be classified into three types; confined, semi-confined and unconfined, according to the condition of canyon and the levees on both sides. Oil one hand, along the transport direction, channel system evolves from confined to unconfined. Within channel systems, channel complexes, including two types of incised and enveloped, are the most important reservoir bodies. On the other hand, there is a channel complex evolution from incised to enveloped vertically. The geological factors exert impacts of different levels on the architecture of the turbidite channels in different sedimentary systems or even within the same system.

在活性污泥中筛出高效复合菌剂用于生物转鼓去除苯乙烯废气。通过单因素实验考察NaCl质量分数、pH、温度、转速和气体流量对生物转鼓去除苯乙烯废气的影响,发现前3者才有显著影响(P<0.05)。进一步对这3种因素进行响应面优化实验,发现温度影响最小,pH影响最大。当pH为7.0、温度为33.46℃、NaCl质量分数为0.97%时,苯乙烯去除率最大,达到96.49%。微生物群落分析表明,生物转鼓中的优势菌门为变形菌门(Proteobacteria),相对丰度约72%;优势菌属为假单胞菌属(Pseudomonas)和罗河杆菌属(Rhodanobacter),相对丰度分别为34.86%、7.69%。
