Oxygenic photosynthetic organisms use solar energy to split water (H2O) into protons (H+), electrons (e(-)), and oxygen. A select group of photosynthetic microorganisms, including the green alga Chlamydomonas reinhardtii, has evolved the additional ability to redirect the derived H+ and e(-) to drive hydrogen (H-2) production via the chloroplast hydrogenases HydA1 and A2 (H(2)ase). This process occurs under anaerobic conditions and provides a biological basis for solar-driven H-2 production. However, its relatively poor yield is a major limitation for the economic viability of this process. To improve H-2 production in Chlamydomonas, we have developed a new approach to increase H+ and e(-) supply to the hydrogenases. In a first step, mutants blocked in the state 1 transition were selected. These mutants are inhibited in cyclic e(-) transfer around photosystem I, eliminating possible competition for e(-) with H(2)ase. Selected strains were further screened for increased H-2 production rates, leading to the isolation of Stm6. This strain has a modified respiratory metabolism, providing it with two additional important properties as follows: large starch reserves ( i.e. enhanced substrate availability), and a low dissolved O-2 concentration (40% of the wild type (WT)), resulting in reduced inhibition of H2ase activation. The H-2 production rates of Stm6 were 5 - 13 times that of the control WT strain over a range of conditions ( light intensity, culture time, +/- uncoupler). Typically, similar to 540 ml of H-2 liter(-1) culture ( up to 98% pure) were produced over a 10-14-day period at a maximal rate of 4 ml h(-1) ( efficiency = similar to 5 times the WT). Stm6 therefore represents an important step toward the development of future solar-powered H-2 production systems.

During aestivation, the gut of the green-striped burrowing frog, Cyclorana alboguttata undergoes significant morphological down-regulation. Despite the potential impact such changes might have on the re-feeding efficiency of these animals following aestivation, they appear to be as efficient at digesting their first meals as active, non-aestivating animals. Such efficiency might come about by the rapid restoration of intestinal morphology with both arousal from aestivation and the initial stages of re-feeding. Consequently, this study sought to determine what morphological changes to the intestine accompany arousal and re-feeding following 3 months of aestivation. Arousal from aestivation alone had a marked impact on many morphological parameters, including small and large intestine masses, small intestinal length, LF heights, enterocyte cross-sectional area and microvilli height and density. In addition, the onset of re-feeding was correlated with an immediate reversal of many morphological parameters affected by 3 months of aestivation. Those parameters that had not returned to control levels within 36 h of feeding generally had returned to control values by the completion of digestion (i.e. defecation of the meal). Re-feeding was also associated with several changes in enterocyte morphology including the incorporation in intracytoplasmic lipid droplets and the return of enterocyte nuclear material to the 'active' euchromatin state: In conclusion, morphological changes to the gut of aestivating frogs which occur during aestivation are transitory and rapidly reversible with both arousal from aestivation and re-feeding. The proximate causes behind these transitions and their functional significance are discussed. (C) 2005 Elsevier Inc. All rights reserved.

Online case studies. Managing Innovation is an established, bestselling text for MBA, MSc and advanced undergraduate courses on management of technology, innovation management and entrepreneurship. It is also used widely by managers in both the service and manufacturing sectors. Now in its fourth edition, Managing Innovation has been fully revised and updated based on extensive user feedback to incorporate the latest findings and techniques in innovation management. The authors have included a new and more explicit innovation model, which is used throughout the book and have introduced two new features – Research Notes and Views from the Front Line – to incorporate more real life case material into the book. The strong evidence–based and practical approach makes this a must–read for anyone studying or working within innovation. An extensive website accompanies this text at www.managing–innovation.com. Readers can browse an online database of audio and video clips, as well as case study material, interactive exercises and tools for innovation, whilst lecturers can find additional support material including instructor slides and teaching guides and tips. "Tidd and Bessant's text has become a standard for students and practitioners of innovation. They offer a lively account on innovation management full of interesting and new examples, but one that at the same is rigorously anchored in what we have learned over the last thirty years on how to manage that ultimate business challenge of renewing products, processes, and business models. Those who want to innovate must read this book." — Professor Arnoud De Meyer, Director, Judge Business School, University of Cambridge, UK "Innovation matters and this book by two leaders in the field which is clear and practical as well as rigorous should be essential reading for all seeking to study or to become involved in innovation." — Chris Voss, Professor of Operations and Technology Management, London Business School "...comprehensive and comprehensible compendium on the management of innovation. It is very well organized and very well presented. A pedagogic tool that will work at multiple levels for those wishing to gain deeper insights into some of the most challenging and important management issues of the day." — David J. Teece, Thomas W. Tusher Professor in Global Business, Haas School of Business, University of California, Berkeley, USA "Those of us who teach in the field of Innovation Management were delighted when the first edition of this book appeared 11 years ago. The field had long been in need of such a comprehensive and integrated empirically–based work. The fact that this is now the 4th edition is clear testimony to the value of its contribution. We are deeply indebted to the authors for their dedication and diligence in providing us with this updated and expanded volume." — Thomas J. Allen,Howard W. Johnson Professor of Management, MIT Sloan School of Management, USA.
