The gaseous plant hormone ethylene regulates many processes of high agronomic relevance throughout the life span of plants. A central element in ethylene signaling is the endoplasmic reticulum （ER）-Iocalized membrane protein ETHYLENE INSENSITIVE2 （EIN2）. Recent studies indicate that in response to ethylene, the extra-membranous C-terminal end of EIN2 is proteolytically processed and translocated from the ER to the nucleus. Here, we report that the conserved nuclear localization signal （NLS） mediating nuclear import of the EIN2 C-terminus provides an important domain for complex formation with ethylene receptor ETHYLENE RESPONSE1 （ETR1）. EIN2 lacking the NLS domain shows strongly reduced affinity for the receptor. Interaction of EIN2 and ETR1 is also blocked by a synthetic peptide of the NLS motif. The corre- sponding peptide substantially reduces ethylene responses in planta. Our results uncover a novel mecha- nism and type of inhibitor interfering with ethylene signal transduction and ethylene responses in plants. Disruption of essential protein-protein interactions in the ethylene signaling pathway as shown in our study for the EIN2-ETR1 complex has the potential to guide the development of innovative ethylene antagonists for modern agriculture and horticulture.

Ethylene insensitive 2 （EIN2）, an integral membrane protein of the ER network, has been identified as the central regulator of the ethylene signaling pathway. Still, the mechanism by which the ethylene signal is transferred from the receptors to EIN2 has not been solved yet. Here, we show that protein phosphorylation is a key mechanism to control the interaction of EIN2 and the receptors. In vivo and in vitro fluorescence studies reveal that the kinase domain of the receptors is essential for the interaction. Cyanide, an ethylene agonist, which is known to reduce auto-phosphorylation of the ethylene receptor ethylene resistant 1 （ETR1） or a mutation in the kinase domain of ETR1 that prevents autophosphorylation （H353A）, increases the affinity of the receptors for EIN2. On the other hand, mimicking permanent auto-phosphorylation of ETR1 as in the mutant H353E releases the EiN2-ETR1 interaction from the control by the plant hormone. Based on our data, we propose a novel model on the integration of EIN2 in the ethylene signaling cascade.

For refurbishment and state review of an existing old building, a new model reflecting the current state is often required especially when the original plans are no longer accessible. Laser scanners are used more and more as surveying instruments for various applications because of their high-precision scanning abilities. For buildings, the most notable and widely accepted product data model is the IFC product data model. It is designed to cover the whole lifecycle and supported by various software vendors and enables applications to efficiently share and exchange project information. The models obtained with the laser scanner, normally sets of points ('point cloud'), have to be transferred to an IFC compatible building information model to serve the needs of different planning states. This paper presents an approach designed by the German Research Center in Karlsruhe (Forschungszentrum Karlsruhe) to create an IFC compatible building information model from laser range images. The methodology through the entire process from data acquisition to the IFC compatible product model was proposed in this paper. In addition, IFC-Models with different level of detail (LoDs) were introduced and discussed within the work.

In this study, I show that human fights are historical projects. They are legal inventions and institutional structures and respond to historical injustices and serious atrocities suffered by people, or which threaten them. It is useful therefore to first distinguish, both historically and systematically, different conceptions of human fights from a concept of human fights. I will distinguish three conceptions： national, international and transnational. Included in national conceptions are the human fights declarations of North America （1776） and France （1789）. The starting event of the international conception is the Universal Declaration of Human Rights by the United Nations after the Second World War in 1948. And it can be argued that a transnational conception of human fights that better fits the globalised world and the already global developments in intemational law and governance is needed.

Tensions and oppositions between the individual and community have accompanied the discourse on human rights from the beginning. I want to first recall how in the UDHR （1948） and in the major human rights treaties, the rights and obligations of individuals are regulated towards communities. I then want to investigate whether the talk of ＂collective human rights＂, understood as ＂third- generation＂ rights, are of equal value to be set with individual human rights. Against communitarian arguments for the primacy of community-related duties one can stress an expansion of a liberal concept of human rights by the inclusion of justice demands and social human rights. To show that special community needs can be protected and promoted through individual human rights and national col- lective rights, I used the example of the protection of minorities. Finally, I will explain why human rights are not a comprehensive theory of the good and illustrate with this the limits, and also the original strength of human rights. We should not overestimate human rights, but also we should be aware that a sober understanding of human rights is philosophically reasonable, legally possible and politically of great importance.

The arc furnace technology is an ideally suited process for the treatment of hazardous and problematic waste. The operation conditions of the furnace can be adapted for optimal transformation of the waste material input into raw materials and usable products. The process can significantly reduce the impact of contaminated wastes and industrial residues, and enable material conversion and separation. Thus, the products of the process have various applications. The capability of the process is illustrated with three examples, the treatment of bottom ash and filter ash from waste incineration plants, of stainless steel slags and of chromium-containing residues from the refractory industry.
