Zeolite synthesis was studied using two silica rich filtration residues (FR 1 and FR 2) as Si-source and sodium aluminate in a direct synthesis at 60°C at strong alkaline conditions (8 M - 16 M NaOH). In addition to these one-pot syntheses, a two-step process was investigated. Here, an alkaline digestion of FR at 60°C was followed by gel precipitation with sodium aluminate and gel crystallization under usual conditions of 80°C - 90°C. The results show that the substitution of chemical reagent sodium silicate by a waste material like FR as Si-source is possible but requires fine tuning of the reaction conditions as zeolite crystallization is a process under kinetic control. The solubility behaviour and impurities of the inserted filtration residues strongly influenced the course of reaction. Thus zeolites like hydrosodalite or intermediate zeolite between cancrinite and sodalite, or zeolite NaA or Z-21 in cocrystallization with hydrosodalite could be observed in the one pot syntheses already in a short time interval between 1 - 4 h depending on the alkalinity. The two step process yield to zeolites NaA and NaX in very good quality. The reaction process of FR in both reaction methods was characterized by chemical analyses, X-ray powder diffraction, Fourier transform infrared spectroscopy as well as scanning electron microscopy. Surface area and water content of selected products were further characterized by the BET-method and by thermogravimetry. Summing up the results, we can show that zeolite formation from filtration residues is possible by several reaction procedures as model cases for a re-use of industrial waste materials. Beside the importance for environmental protection, the reactions are of interest for zeolite chemistry as the re-use of FR is possible under economically conditions of low energy consumption at 60°C and short reaction periods.

急性胰腺炎严重程度的准确分级对于临床实践和研究十分重要。在临床实践中，准确的分型有助于正确地评估疾病的严重程度，监测疾病的发展，制定治疗策略。而临床研究中，准确的分型对于患者的正确入组、实验结果的有效性都有很大影响。一个多世纪以来，急性胰腺炎的严重程度被简单地分为轻型和重型，而且对于轻型和重型的定义尚未统一。近年来，研究发现重型胰腺炎又有不同的亚组，而不同亚组患者的预后有很大差异，轻型和重型二分法的局限性慢慢显现。

2011—2014年俄罗斯联邦在北极高纬度地区采集了大量新的二维地震数据,结合地质和地球物理资料,很好地反映了包括欧亚海盆(中部和东部)、加克洋中脊及向拉普捷夫海过渡区域的基底结构和上覆沉积物的层序结构特征。通过地震剖面发现,南森海盆在C20(43.43 Ma)时期、阿蒙森海盆在C21(45.7Ma)时期以及两个盆地在C13(33 Ma)时期的基底地形均发生了显著变化。首次揭示了欧亚海盆中部、东部共轭海盆及其边缘的基底结构特征,表明洋壳增生的非对称性,自大陆裂解以来阿蒙森海盆洋壳厚度相对南森海盆少增生了约10%。阿蒙森海盆东部,C13(33 Ma)以来洋中脊开始隆升。我们识别出欧亚海盆四期不同的沉积层序,分别是:始新世早期和中期(约56—45.7 Ma),中始新世至早渐新世(45.7—33.2 Ma),早渐新世至早中新世(33.2—19.7 Ma)和早中新世至今(19.7 Ma以来)。它们与根据磁数据确定的海洋岩石圈年龄有关。地震资料首次揭示加克洋中脊东端最深处(5215 m)早期轴向隆起和侧翼上形成的火山构造。加克洋中脊两侧具有非对称性,其地壳薄,地形结构规则间隔、表面崎岖,类似于超慢速扩张洋中脊,暗示其构造演化阶段的周期性。罗蒙诺索夫海岭和拉普捷夫海之间的哈坦加-罗蒙诺索夫转换断层在少数几条地震剖面上显示,运动学分析表明大陆裂解后,它可能最多只活动了10myr。
