The thermosome of the archaeon Thermoplasma acidophilum is composed of two subunits, alpha and beta, which are arranged in two stacked, eight-membered rings. Electron cryo-microscopy in conjunction with image analysis revealed a 4-fold symmetry in the heterooligomeric alpha + beta thermosome isolated from Thermoplasma, but not in the homooligomeric(More)
The thermosome, the chaperonin of the archaea, and its homologue from the cytosol of eukaryotes, known as TRiC or CCT, form a distinct subfamily of the chaperonins that does not depend on a co-chaperonin for protein folding activity. Recent structural data obtained by cryo- electron microscopy and X-ray crystallography provide the first insights into a(More)
The objective of green logistics has thus far failed. For example, the share of greenhouse gas emissions by the transportation and logistics sector in Europe rose from 16.6% in 1990 to 24.3% in 2012. This article analyzes the reasons behind this failure by drawing on political, economic and business as well as social motivations and examples. At the core of(More)
Supplier Evaluation is of increasing importance for companies and their further business development due to the fact that companies are concentrating on their core competencies. Next to that a distinctive supplier evaluation includes all internal departments and their feedback about supplier‟s performance to receive a whole picture of supplier‟s potential.(More)
This paper provides an approach to use a continuous track and trace system based on GPS (Global Positioning System) technology in production networks. Therefore the ild institute for logistics and service management (FOM Essen, Germany) operates a new GPS based track and trace system with the name GPS. LAB. The results of the first trials with the existing(More)
As a result of global societal and economic as well as technological developments logistics and supply chains face unprecedented challenges. Climate change, the need for more sustainable products and processes, major political changes, the advance of “Industry 4.0” and cyber-physical system are some of the challenges that require radical solutions, but also(More)
The authors develop and implement a holistic and applicable performance measurement system to measure the performance of humanitarian supply chains during both disaster situations and development. The system could help no-profit organization to make better decisions, improve their performance and provide accountability.
The most valuable assets of a microbiologist microorganisms must be well enough acquainted are his set of stock cultures, and he must handle with the component taxises that he will know the them in such a manner as to preserve that value media and conditions best suited to permit and to profit by their use. The purposes of this typical growth of any strain;(More)
We have developed homogeneous miniaturized assays to measure ligand binding to either intact cells or receptor-containing membrane fragments by analysis of particle brightness. As an example, the affinities and inhibition constants of fluorescently labeled interleukin-8 (IL-8) and a low-molecular-weight antagonist toward the receptors CXCR1 and CXCR2, which(More)
Sustainable and green logistics concepts are a major trend in global supply chains. An important research question in this context is the topic of a possible interdependence between green logistics measures and overall volatility in supply chains, discussed in logistics literature e.g. as ‘bullwhip effect’. This research paper therefore tries to give an(More)
