Rubisco regulation: a role for inhibitors

Abstract: In photosynthesis Rubisco catalyses the assimilation of CO2 by the carboxylation of ribulose-1,5-bisphosphate. However, the catalytic properties of Rubisco are not optimal for current or projected environments and limit the efficiency of photosynthesis. Rubisco activity is highly regulated in response to short-term fluctuations in the environment, although such regulation may not be optimally poised for crop productivity. The regulation of Rubisco activity in higher plants is reviewed here, including the role of Rubisco activase, tight binding inhibitors, and the impact of abiotic stress upon them.

Creating customer loyalty through service customization

Abstract: – Although practitioners and scholars alike embrace service customization as a possibly powerful management instrument, its impact on customer relationships as well as contingencies for its effective application are not well understood. Drawing from relationship marketing and exchange theory, this paper aims to develop a model of customer relationship outcomes of service customization and the efficacy of service customization., – Two large‐scale, representative, cross‐sectional studies in different service industries based on the European Customer Satisfaction Index framework are conducted, and PLS path modeling is applied to test the model., – Customization increases perceived service quality, customer satisfaction, customer trust, and ultimately customer loyalty toward a service provider. Customization has both direct and mediated effects on customer loyalty and interacts with the effects of customer satisfaction and customer trust on loyalty., – Service customization is a viable instrument for relationship marketing. Its efficacy depends on customer satisfaction and customer trust. While this study solely focuses on the impact of service customization, future research could assess the relative importance of service customization in the presence of other relationship marketing instruments., – Service providers can use service customization as an effective instrument for achieving not only higher customer satisfaction, but also higher customer loyalty. Service customization is most effective for companies that have deficits in satisfying their customers, while at the same time their customer relationships are characterized by a high level of trust. These results help managers to decide upon resource allocation to enhance customer satisfaction, trust and loyalty., – This paper investigates the simultaneous effects of service customization on customer loyalty and other relationships variables and offers new insights relatively to the nature and size of customization effects. It fills an important gap in the knowledge of customization outcomes, and clarifies under which circumstances service customization is most effective. The paper is of great value for service providers that face the decision whether to customize their offering or not.

Microgrids - Large Scale Integration of Microgeneration to Low Voltage Grids

Abstract: Microgrids comprise Low Voltage distribution systems with distributed energy sources, such as micro-turbines, fuel cells, PVs, etc., together with storage devices, i.e. flywheels, energy capacitors and batteries, and controllable loads, offering considerable control capabilities over the network operation. These systems are interconnected to the Medium Voltage Distribution network, but they can be also operated isolated from the main grid, in case of faults in the upstream network. From the customer point of view, Microgrids provide both thermal and electricity needs, and in addition enhance local reliability, reduce emissions, improve power quality by supporting voltage and reducing voltage dips, and potentially lower costs of energy supply. This paper outlines selected research findings of the EU funded MICROGRIDS project (Contract ENK-CT-2002-00610). These include: • Development and enhancement of Microsource controllers to support frequency and voltage based on droops. Application of software agents for secondary control. • Development of the Microgrid Central Controller (MGCC). Economic Scheduling functions have been developed and integrated in a software package able to simulate the capabilities of the MGCC to place bids to the market operator under various policies and to evaluate the resulting environmental benefits. • Analysis of the communication requirements of the Microgrids control architecture • Investigation of alternative market designs for trading energy and ancillary services within a Microgrid. Development of methods for the quantification of reliability and loss reduction. • Initial measurements from an actual LV installation.

Families of Sordariomycetes

Abstract: Sordariomycetes is one of the largest classes of Ascomycota that comprises a highly diverse range of fungi characterized mainly by perithecial ascomata and inoperculate unitunicate asci. The class includes many important plant pathogens, as well as endophytes, saprobes, epiphytes, coprophilous and fungicolous, lichenized or lichenicolous taxa. They occur in terrestrial, freshwater and marine habitats worldwide. This paper reviews the 107 families of the class Sordariomycetes and provides a modified backbone tree based on phylogenetic analysis of four combined loci, with a maximum five representative taxa from each family, where available. This paper brings together for the first time, since Barrs’ 1990 Prodromus, descriptions, notes on the history, and plates or illustrations of type or representative taxa of each family, a list of accepted genera, including asexual genera and a key to these taxa of Sordariomycetes. Delineation of taxa is supported where possible by molecular data. The outline is based on literature to the end of 2015 and the Sordariomycetes now comprises six subclasses, 32 orders, 105 families and 1331 genera. The family Obryzaceae and Pleurotremataceae are excluded from the class.
