前言现代科学推动了回收材料的再利用,其中包括以各种方法回收的橡胶。例如,许多地区已颁布了环保条例,不允许深埋废轮胎和其它废橡胶,要求将其回收。但是最有效的还是市场的推动。

再生IIR是轮胎工业中广泛应用的一种重要配合剂。用再生IIR部分替代IIR或BIIR可改善胶料工艺性能 ,并对胶料的某些非常重要的性能 (包括胶料成本 )有着积极的影响。　　对气密层来说 ,最有意义的工艺性能改进是提高了轮胎成型和硫化过程中的气密性。含有再生IIR的气密层胶料具有较低的透气率 ,使制造商能够减薄气密层 ,同时不降低其气密性。胶料的耐老化性能也提高了 ,特别是老化后的屈挠疲劳寿命大大提高。

混炼传统的白炭黑填充胶料需要长的混炼周期,而配合预硅烷化白炭黑和母炼胶的胶料需要非常短的混炼周期。极性较高的加工助剂Ultra-DFR90特别适用于配合母炼胶的胶料,所需的混炼时间非常短。总之,以非常短混炼周期混炼配合母炼胶的胶料其性能与用长混炼周期混炼的传统胶料的性能相当,且具有生产周期短、胶料加工性能好等优点。因此,与传统的白炭黑/硅烷体系相比,天然橡胶-白炭黑母炼胶是一种较好的替代材料。

实验设计(DOE)是制定平衡炭黑填充航空轮胎胎面胶所需特性的最佳参数设置的合适工具。在实验设计研究中发现,转子转速和填料混合时间是影响航空轮胎胎面胶性能的最重要因子。通过优化这些因子的设定条件,可以满足航空轮胎胎面应用所需的性能。航空轮胎胎面胶研究的发展趋势是滞后损失(tanδ)尽可能低,耐磨性尽可能高,今后仍需进一步优化配方和改善加工工艺。通过在炭黑填充混炼胶中掺入一小部分白炭黑、适量的硅烷偶联剂和树脂是在保持高耐磨性的前提下进一步降低滞后损失的方法。

白炭黑和炭黑为广泛用于橡胶中的补强填料.由于白炭黑和炭黑表面特征不相同,它们虽然都容易形成聚集体,但形成聚集体的原因却不相同,导致它们的分散能力不相同.炭黑-炭黑相互作用主要是由范德华作用力引起的,其在混炼过程中容易被破坏.白炭黑聚集体是由氢键、范德华作用力和其他物理作用力共同作用形成的更强的填料-填料相互作用.白炭黑表面的硅烷醇基团使其具有高极性和亲水性.因此,白炭黑与非极性橡胶如天然橡胶（NR）、丁苯橡胶（SBR）和顺丁橡胶（BR）不相容,但其与极性橡胶如氯丁橡胶和丁腈橡胶（NBR）的相容性较好.

In this review, combined post-mortem brain magnetic resonance imaging(MRI) and histology studies are highlighted, illustrating the relevance of translational approaches to de?ne novel MRI signatures of neuropathological lesions in neuroin?ammatory and neurodegenerative disorders. Initial studies combining post-mortem MRI and histology have validated various MRI sequences,assessing their sensitivity and speci?city as diagnostic biomarkers in neurologic disease. More recent studies have focused on de?ning new radiological(bio)markers and implementing them in the clinical(research) setting. By combining neurological and neuroanatomical expertise with radiological development and pathological validation,a cycle emerges that allows for the discovery of novel MRI biomarkers to be implemented in vivo. Examples of this cycle are presented for multiple sclerosis, Alzheimer's disease, Parkinson's disease, and traumatic brain *** applications have been shown to be successful, while others require further validation. In conclusion, there is much to explore with post-mortem MRI and histology studies, which can eventually be of high relevance for clinical practice.

＂Our relation to the past is being transformed by digital media. Internet and digital databases increase the presence of the past and remake our connection to both past and present＂（Manoff, 2010, p. 9）. The use of archive footage in documentary filmmaking has increased significantly, since the digitalization of audio-visual archives. Access is facilitated by databases and different interfaces. The theorization about the particular impacts of archive footage on the documentary text has not received much attention as yet as archive usage has been seen as unproblematic and digital archives as just ＂handy＂. This paper is a first step in the development of a taxonomy of how archive footage is being used by documentary filmmakers, while taken into account the production practices and the processes of archivization of archive materials.

The application of polymer chain statistics, or configurational statistics, to thenucleic acids has helped to relate the subtle features of chemical architecture to thephysieal and biological properties of these maeromoleeules. Various configuration-dependentproperties (such as mean-square dimensions, average nmr coupling constants,and loop closure probabilities) can be calculated with ready facility in terms of thefixed structural parameters (i. e., bond lengths and valence bond angles) and the seveninternal torsional variables of the nueleotide repeating units. In fact, the configurationalcomputations are the only available means to study the distribution of conformations ofa flexible polynueleotide. The statistical studies are also useful in testing variouseonformational models of the chain backbone. The validity or rejection of a particulartorsional scheme is determined by its ability to account for the various eonfiguration-dependentproperties.

Portal venous aneurysm (PVA) is a rare condition characterized by dilatation of the portal venous system. PVA manifestation of symptoms is varied and depends on the aneurysm size, location and related-complications, such as thrombosis. While the majority of reported cases of PVA are attributed to portal hypertension, very little is known about the condition's pathophysiology and clinical management remains a challenge. Here, we describe a 67-year-old woman who presented with complaint of dyspepsia and without a significant medical history, for whom PVA was incidentally diagnosed. The initial upper abdominal ultrasound revealed marked dilatation of the main portal vein, and subsequent contrast-enhanced computed tomography with angiography revealed a large aneurysm arising from the extrahepatic troncus portion of the portal vein, as well as gastroesophageal varices. A conservative approach using beta-blocker therapy was chosen. The patient was followed-up for 60 mo, during which time the asymptomatic status was unaltered and the PVA remained stable.
