Graphene oxid. shows great promise as a material for biomed.cal applications, e.g., as a multi-d.ug d.livery platform. With this in view, reports of stud.es on the interaction between nanosized.graphene oxid. flakes and.biological cells are beginning to emerge. However, the number of stud.es remains limited. and.most used.labeled.graphene oxid. samples to track the material upon end.cytosis. Unfortunately, the labeling process alters the surface functionality of the graphene oxid., and.this ad.itional funcfionalization has been shown to alter the cellular response. Hence, in this work we used.label-free graphene oxid.. We carefully tracked.the uptake of three d.fferent nanoscale graphene oxid. flake size d.stributions using scanning/transmission electron microscopy. Uptake was investigated.in und.fferentiated.human monocyte cells （THP-1） and.d.fferentiated.macrophage cells. The d.ta show clear size d.pend.nce for uptake, such that larger graphene oxid. flakes （and.clusters） are more easily taken up by the cells compared.to smaller flakes. Moreover, uptake is shown to occur very rapid.y, within two min of incubation with THP-1 cells. The d.ta highlights a crucial need.for cellular incubation stud.es with nanoparticles, to be cond.cted.for short incubation period. as certain d.pend.ncies （e.g., size and.concentration） are lost with longer incubation period..

A long-term pilot-scale H_(2)-based.membrane biofilm reactor(MBfR)was tested.for removal of nitrate from actual ground.ater.A key feature of this second.eneration pilot MBfR is that it employed.lower cost polyester hollow fibers and.still achieved.high load.ng *** stead.-state maximum nitrate surface load.ng at which the effluent nitrate and.nitrite concentrations were below the Maximum Contaminant Level(MCL)was at least 5.9 g·N·(m^(2)·d.^(–1),which correspond. to a maximum volumetric load.ng of at least 7.7 kg·N·(m^(3)·d.^(–1).The stead.-state maximum nitrate surface area load.ng was higher than the highest nitrate surface load.ng reported.in the firstgeneration MBfRs using composite fibers(2.6 g·N·(m^(2)·d.^(–1)).This work also evaluated.the H_(2)-utilization efficiency in *** measured.H_(2)supply rate was only slightly higher than the stoichiometric H_(2)-utilization ***,H_(2)utilization was controlled.by d.ffusion and.was close to 100%efficiency,as long as biofilm accumulated.on the polyester-fiber surface and.the fibers had.no leaks.

测量了阴极射线磷光体的绝对效率随电压和电流密度的变化。这个结果与过去报导的最高值完全一致。亮度与电压关系曲线的斜率变化说明,电压依赖关系的变化可能发生于X射线激发电位,这些观察现象与其他作者所报导的用X射线激发闪烁晶体的结果有一定关系。情况说明,本征效率与入射电子束的动能无关的这种设想不大可能,除非这个能量超过基质的KX射线能级。

Linking a Game Engine Environment to Architectural Information on the Semantic Web

引用

Journal of Civil Engineering and.Architecture 2011年第9期5卷 787-798页

作者： Pieter Pauwels Ronald.d. meyer Jan Van Campenhout d.partment of Architecture and.Urban Planning Faculty of Engineering and Architecture Ghent University Ghent 9000 Belgium d.partment of Electronics and.Information Systems Faculty of Engineering and Architecture Ghent University Ghent 9000 Belgium

Because of the importance of graphics and.information within the d.main of architecture, engineering and.construction （AEC）, an appropriate combination of visualization technology and.information management technology is of utter importance in the d.velopment of appropriately supporting d.sign and.construction applications. Virtual environments, however, tend.not to make this information available. The sparse number of applications that present ad.itional information furthermore tend.to limit their scope to pure construction information and.d. not incorporate information from loosely related.knowled.e d.mains, such as cultural heritage or architectural history information. We therefore started.an investigation of two of the newest d.velopments in these d.mains, namely game engine technology and.semantic web technology. This paper d.cuments part of this research, containing a review and.comparison of the most prominent game engines and.d.cumenting our architectural semantic web. A short test-case illustrates how both can be combined.to enhance information visualization for architectural d.sign and.construction.

关键词： 3d BIM construction ind.stry game engines information semantic web virtual environments visualization.
