In comparison to the established twin-screw machines,the application of a planetary roller granulator for continuous operation of melt granulation is a promising alternative based on the unique process *** initial study focused on the material transport during processing as a key driver for the overall ***,the impact of direct process parameters on the residence time distribution was the main *** investigations are complemented in this study by considering the free processing volume,which is defined by the number of planetary spindles applied within a *** impact on the processing conditions is evaluated with respect to the process setting in terms of feed rate and rotation *** results highlight the potential of altering the underlying transport function in planetary roller melt granulation(PRMG)via the investigated direct process and equipment *** impact of the feed rate is lower in comparison,while a higher rotation speed as well as a higher free processing volume promote material ***,a normalization of the determined residence time distribution(RTD)model data was feasible with respect to the process settings and the number of applied planetary spindles in the processing *** demonstrates the key role of the free processing volume in the fundamental mechanisms of material transport and mixing during PRMG.

纺织助剂中的甲醛测定

国际纺织导报 2016年第10期44卷 56-57页

作者： M.Geubtner G.lang J.P.Moldenhauer S.Schneider-Müller H.Wünsche R.Zyschka 李梦雅(译) 程心怡(译) 罗艳(校) TEGEWA协会整理工作组德国不详

基于更为严厉的甲醛重新分类的背景,TEGEWA协会整理工作组已开发出一种可确定纺织助剂中游离甲醛含量的新方法。目前此法鉴于其统一的程序,可使因不同的内部测试方法而得出不同观点的测试成为过去。

Background:Microvascular invasion(MVI)can only be assessed on a full surgical *** aimed at evaluating,whether the histology of the primary tumor is predictive of MVI in a hepatocellular carcinoma(HCC)***:Patients,who underwent liver resection or orthotopic liver transplantation(OLT)for recurrent HCC from January 2001 until June 2018 were eligible for this retrospective *** specimens were evaluated for HCC subtype/morphology,vessels encapsulating tumor clusters(VETC)-pattern and *** parameters were analyzed using χ^(2)-test andϕ-values,with P values<0.05 being considered ***:Of 230 HCC recurrences,37(16.1%)underwent repeated liver resection(n=22)or OLT(n=15).Of these,67.6%initially exceeded the Milan *** correlated Milan criteria(P=0.005),tumor size(P=0.015)and VETC-pattern(P=0.034)in the primary *** recurrences shared many features of the primary HCC such as tumor grade(P=0.002),VETC-pattern(P=0.035),and MVI(P=0.046).In recurrences,however,only the concordance with the Milan criteria correlated with MVI(P=0.018).No patient without MVI in the primary HCC revealed MVI on early recurrence(<2 years)(P=0.035).Conclusions:HCC recurrences share many biological features of the primary ***,early recurrences of MVI-negative HCC never revealed *** finding offers novel concepts,e.g.,patient selection for salvage OLT.

SmartFactoryKL工作组1 '智能基础设施'专门处理模块化工业4.0生产设施的安全问题。其旨在提供一种工厂结构,通过模块化等手段确保其灵活性和可变性。本安型模块具有常规的功能安全性。但是,模块间依然存在依赖关系。在支持未知模块的模块化系统中,还需要一个新的安全体系结构。去年,该概念被整合到了工业4.0生产设施中,以实例证明该概念可在当今技术的基础上得以实施。在安全和机器通信的实施中,仅采用了一条单线共存。机器和机器模块可以在运行期间插入生产线或从生产线移除,而不会影响工厂的其它部分。必要的安全相关参数将根据此处导入的安全配置文件自动进行协商、配置和发布。要求如下文所述。
