The finite cell method （FCM） combines the high-order finite element method （FEM） with the fictitious domain approach for the purpose of simple meshing. In the present study, the FCM is used to the prandtl-Reuss flow theory of plasticity, and the results are compared with the h-version finite element method （h-FEM）. The numerical results show that the FCM is more efficient compared to the h-FEM for elasto-plastic problems, although the mesh does not conform to the boundary. It is also demonstrated that the FCM performs well for elasto-plastic loading and unloading.

The coating of plastics for optical applications is intended to improve the mechanical durability of soft polymers and to serve an antireflection function. Usually a classic four-layer antireflection system is added on top of a single-layer hard coating. With needle optimisation,an alternative coating design has been developed. plasma ion assisted deposition was used to deposit coatings upon polymers. Uniform antireflection and high scratch resistance have been achieved.

Molecular plant 2008年第2期1卷 229-237页

Ruperti I. paponov K. palme Institute of Biology Ⅱ Faculty of Biology University of Freiburg D-79104 Freiburg Germanya dipartimento di Agronomia Ambientale e produzioni Vegetali Agripolis University of Padova viale dell'Universita 16 35020 Legnaro Italy

The regulation of plant growth responds to many stimuli. These responses allow environmental adaptation, thereby increasing fitness. In many cases, the relay of information about a plant＇s environment is through plant hormones. These messengers integrate environmental information into developmental pathways to determine plant shape. This re- view will use, as an example, auxin in the root ofArabidopsis thaliana to illustrate the complex nature of hormonal signal processing and transduction. It will then make the case that the application of a systems-biology approach is necessary, if the relationship between a plant＇s environment and its growth/developmental responses is to be properly understood.
