    Notizen: Three floR genes were cloned from calf pathogenic Escherichia coli strains, and the efflux-mediated accumulation of florfenicol in the floR gene-JM109 E. coli system was determined by HPLC. The floR genes resulted in a 1356-bp fragment covering the ORF in region 66–1280 coding for 404 amino acids. The common motifs of 12-transmembrane segments efflux pumps family were conserved in the deduced floR amino acid sequences. HPLC results indicated a significant difference in florfenicol accumulation between florfenicol-resistant strains and the susceptible strains, which was almost reversed by the addition of a proton motive force blocker. These results suggest that the florfenicol resistance mediated by the floR gene involves active efflux of florfenicol.

    Notizen: The title complex, [Mn(C5H4NCO2)2(C5H4NCOOH)]OH, consists of a cation and a hydroxide ion. The Mn atom is coordinated by three N atoms and three O atoms from three pyridinecarboxylate ligands, and has a distorted octahedral geometry, with Mn—N distances ranging from 2.157 (1) to 2.233 (1) Å and Mn—O distances from 1.910 (1) to 1.927 (4) Å. One ligand is protonated as the acid form. This forms one of two independent hydrogen bonds, to the anion.

    Notizen: Tests have been done to study the compound mineral admixtures of lithium-saltindustrial residue (LSR) and fly ash. The results indicate that the addition of LSR plays a significant influence on both pozzolanic activity and strength of concrete at ages of 7d, 28 d, and 60 d respectively. An optimum dosage of LSR is identified in the compound admixtures. It is of certain practical value to the study and application of the high compound admixtures content and high fly ash content concrete

    Beschreibung: To achieve an efficient use and allocation of limited water resources and thus resolve increasing water use conflicts due to fast rising societal water demands, in 2000, the Chinese government started a management strategy of 'Construction of a Water Saving Society (WSS)'. It is guided by the principle that socio-economic development should consider the carrying capacity of the ecosystem and focuses on institutional innovation, building on the water rights concept. This paper explores the innovation process during the transition towards WSS by investigating the development course of the innovation process during the transition towards WSS, and the adaptive capacity of the existing water management regime underlying the innovation process. Accordingly, an analysis framework consisting of three types of governance activities and factors determining a regime's adaptive capacity was developed, based on the theory of transition management and adaptive governance. The Tianjin and Zhangye WSS experiments were selected for a deep understanding of local innovations. It is revealed that co-evolution of all three types of governance activities that are claimed to be essential for transition has taken place. However, the current adaptive capacity of the regime still needs further enhancement to support the transition towards the desired WSS in China. Finally, some general insights are provided for policy innovations in other political economies.

    Beschreibung: For decades, the Chinese government has been searching for solutions to cope with the increasing imbalance between the supply and demand of water in the Yellow River Basin. This paper aims at a better understanding of the development of the water allocation regime in the Yellow River Basin between 1950 and 2009, introducing a fresh perspective based on the notion of "regime transition". Accordingly, we investigated 1) whether so-called "Windows of Opportunity for Transition (WOPTs)" emerged, triggering a transition, and whether WOPT(s) resulted in a stable transition towards the new regime; 2) how informal learning processes and epistemic communities have contributed to the regime change. We adapted Kingdon's "multiple stream model" and identified four WOPTs from the 1950s, analyzing the reconfiguration process of the regime after the onset of the transition. Our examples of two types of informal learning processes demonstrate their contribution to the creation of WOPTs and the reconfiguration of the regime. Furthermore, this study indicates, in a qualitative manner, how epistemic communities contribute to the knowledge base of the regime, and thus to its development. Finally, we have provided a general insight into the further development of the water allocation regime and highlighted potential avenues for further studies.

    Beschreibung: This study aims to investigate whether, to what extent and how a transition toward integrated flood management has taken place in the Dongting Lake area at the middle Yangtze. Accordingly, we conducted a longitudinal research of its flood management (1949–2009). We developed an analytical framework linking regime components to two societal learning types (double and triple-loop learning) that are key to a regime transition. Our study shows that the transition toward integrated flood management has already started, but the whole regime transformation will still take time to complete, due to, for example, the not-yet-ready decision-making processes that shape the structure changes as well as the incompatibilities between what is on paper and real implementation. To understand how the regime transition took place, we investigated where and how triple-loop learning was initiated as well as how so-called "informal learning processes" has contributed to the transition of Dongting flood management.
