The PNIPAAm and PSA hydrogel films were prepared by means of in situ photopolymerization directly inside the fluidic channel of a microfluidic chip fabricated by combining Si and SU-8 technologies. The swelling/shrinking properties and height changes of the PNIPAAm and PSA films inside the fluidic channel were studied at temperatures of deionized water from 14 to 36 °C and different pH values (pH 3-12) of Titrisol buffer, respectively. Additionally, in separate experiments, the lower critical solution temperature (LCST) of the PNIPAAm hydrogel was investigated by means of a differential scanning calorimetry (DSC) and a surface plasmon resonance (SPR) method. Mass-flow measurements have shown the feasibility of the prepared hydrogel films to work as an on-chip integrated temperature- or pH-responsive microvalve capable to switch the flow channel on/off.}, language = {en} } @article{Baehr2012, author = {B{\"a}hr, Brigitte}, title = {[Gert Hoepner] im Interview zum Thema ; Verpackungspolitik - mehr als H{\"u}lle}, series = {Packaging journal : Technologie, Logistik, Marketing, Produkte}, journal = {Packaging journal : Technologie, Logistik, Marketing, Produkte}, number = {5}, publisher = {Ella Verlag}, address = {H{\"u}rth}, issn = {1610-0336}, pages = {78 -- 80}, year = {2012}, language = {de} } @phdthesis{Buedenbender2012, author = {B{\"u}denbender, Martin}, title = {Entflechtungskonzepte f{\"u}r Strom{\"u}bertragungsnetze : ein {\"o}konomischer Vergleich}, series = {M{\"u}nstersche Schriften zur Kooperation ; Bd. 101}, journal = {M{\"u}nstersche Schriften zur Kooperation ; Bd. 101}, publisher = {Shaker}, address = {D{\"u}ren}, isbn = {978-3-8440-1460-0}, pages = {XVII, 401 S. : Ill., graph.

Although the implementation of an NGN seems to be merely a modification of the network infrastructure, it may trigger or require changes in the whole company, because it builds upon the separation between service and transport, a flexible bundling of services to products and the streamlining of the IT infrastructure. We propose a holistic framework, structured into the layers 'strategy', 'processes' and 'information systems' and incorporate into each layer all concepts necessary for the implementation of an NGN, as well as the alignment of these concepts. As a first proof-of-concept for our framework we have performed a case study on the introduction of NGN in a large telecommunication company; we show that our framework captures all topics that are affected by an NGN implementation.}, language = {en} } @inproceedings{CzarneckiWinkelmannSpiliopoulou2012, author = {Czarnecki, Christian and Winkelmann, Axel and Spiliopoulou, Myra}, title = {Transformation in Telecommunication - Analyse und Clustering von Real-life Projekten}, series = {Multikonferenz Wirtschaftsinformatik 2012}, booktitle = {Multikonferenz Wirtschaftsinformatik 2012}, editor = {Mattfeld, Dirk Christian and Robra-Bissantz, Susanne}, publisher = {Gito}, address = {Berlin}, isbn = {9783942183635}, pages = {985 -- 998}, year = {2012}, abstract = {Die Ver{\"a}nderungen des Telekommunikationsmarktes haben in der Praxis zu einer Vielzahl von Transformationsprojekten gef{\"u}hrt.

Virtually any surface - animal, mineral, or vegetable - is a subject for microbial colonization and subsequent biofilm formation. It would be adequate to name just a few notorious examples on microbial colonization of contact lenses, ship hulls, petroleum pipelines, rocks in streams and all kinds of biomedical implants. The propensity of microorganisms to become surface-bound is so profound and ubiquitous that it vindicates the advantages for attached forms over their free-ranging counterparts [2]. Indeed, from ecological and evolutionary standpoints, for many microorganisms the surface-bound state means dwelling in nutritionally favorable, non-hostile environments [3]. Therefore, in most of natural and artificial ecosystems surface-associated microorganisms vastly outnumber organisms in suspension and often organize into complex communities with features that differ dramatically from those of free cells [4].}, language = {en} } @book{DigelZhubanovaAkimbekov2012, author = {Digel, Ilya and Zhubanova, Azhar Ahmetovna and Akimbekov, Nuraly Shardarbekovich}, title = {Visual Virology}, address = {Almaty}, isbn = {978-601-247-298-1}, pages = {144 S. : zahlr.
