Hydrothermale Vergasung: Ansätze einer reaktionstechnischen Optimierung
Authors: Kruse A. , Faquir M. 
Published: April 2007

AbstractDie hydrothermale Vergasung ist ein attraktives Verfahren, um Biomasse mit hohem Wassergehalt zur Wasserstoffgewinnung zu nutzen. Diese Reaktion ist kinetisch kontrolliert, was z. B. dazu führt, dass Reaktoren mit Rückvermischung (kontinuierlicher Rührkessel) zu günstigeren Ergebnissen führen als Reaktoren ohne Rückvermischung. Ursache hierfür ist, dass bei Rückvermischung späte Folgeprodukte mit früheren reagieren können.
Biokraftstoffe – Eine Übersicht
Authors: Schaub G. , Vetter A. 
Published: April 2007

AbstractWegen steigender Ölpreise und wachsender Klimabesorgnis haben Biokraftstoffe an Bedeutung gewonnen. Offen ist weiterhin die Frage, welche Kraftstoffe aus Biomasse mit welchen Mengenpotenzialen, charakteristischen Eigenschaften und Umweltauswirkungen die größten Beiträge liefern sollen. Neben dem Qualitätsaspekt ist wegen der gefragten großen Mengen stets der Mengenaspekt wichtig, d. h. erzielbare Erträge von Biomasse‐Rohstoffen sowie Wirkungsgrade/Ausbeuten der technischen Umwandlungsverfahren zum Kraftstoff. Wichtigste Vertreter sind derzeit Fettsäuremethylester, Ethanol sowie für die Zukunft synthetische Kohlenwasserstoffe und Wasserstoff, hergestellt über biotechnologische oder chemische Verfahren. Ursachen der Mengenbegrenzung sind die begrenzte Nettoproduktion der Photosynthese, Anbauflächen, Umwandlungsverluste und insbesondere die Wasserverfügbarkeit. Als Folge können Biokraftstoffe für sich allein nur einen (kleineren) Teil zur Lösung der Rohstoffsicherheit beitragen. Erforderlich sind zusätzlich Effizienzsteigerung, Einsparung im Bereich der Mobilität und Anpassung der Konsumgewohnheiten.
Synthetische Kraftstoffe aus Biomasse: Technik, Entwicklungen, Perspektiven
Authors: Fürnsinn S. , Hofbauer H. 
Published: April 2007

AbstractDurch die aktuellen Entwicklungen im Zusammenhang mit der Verringerung der CO2‐Emissionen sowie der Versorgungssicherheit in Europa ergibt sich ein bereits kurz‐ und mittelfristig großer Bedarf an Biokraftstoffen. Die Erzeugung von synthetischen Biokraftstoffen stellt einen durch große Flexibilität im Hinblick auf die einsetzbaren Rohstoffe und die produzierbaren Kraftstoffe gekennzeichneten Weg dar. Dies erscheint angesichts der ambitionierten politischen Ziele unbedingt nötig. Diese indirekt über Vergasung und anschließende Synthese gewonnenen Kraftstoffe können mit Wirkungsgraden von > 50 % hergestellt werden, wobei auch im Kostenvergleich Konkurrenzfähigkeit zu den heute eingesetzten Biokraftstoffen erster Generation gegeben ist. Neben der Darstellung der zugrundeliegenden Technologien vom Rohstoff bis zum Kraftstoff werden insbesondere Gemeinsamkeiten sowie wichtige Prozessdeterminanten herausgearbeitet.
Status und Zukunft der Biotreibstoffe
Authors: Plass L. , Reimelt S. 
Published: April 2007

AbstractHaupttreiber der zunehmenden Nutzung von Biomasse sind der steigende Energiebedarf generell sowie das Streben vieler Staaten nach mehr Unabhängigkeit von der politisch als unsicher bewerteten Versorgung mit Öl und Gas bei weiter steigenden und stark schwankenden Preisen. Sowohl bei Biodiesel als auch bei Bioethanol bestehen jedoch Rohstoffbegrenzungen für künftiges Wachstum, sowohl was die verfügbaren Flächen angeht als auch im Hinblick auf die bestehende Wettbewerbssituation zur Nahrungsmittelkette. Eine nachhaltige Lösung kann nur in der gesamthaften Nutzung der Biomasse liegen.
Single‐constant simplification of Kubelka‐Munk turbid‐media theory for paint systems—A review
Authors: Berns Roy S. , Mohammadi Mahnaz 
Published: April 2007

AbstractFor opaque coloration systems, Kubelka‐Munk turbid media theory is used commonly to model optical mixing behavior. Most educational publications on the subject use opaque paint systems when describing the two‐constant approach and textile systems when describing the single‐constant simplification. Because of the differences in defining concentration for these systems and the corresponding degrees of freedom, the single‐constant simplification for paint and textile systems are not identical. The second edition of “Principles of Color Technology” showed a numerical example for an opaque paint system modeled using the textile equations. The third edition used the same example but modified the degrees of freedom, a hybrid of the paint and textile approaches. Recent research by Berns and Mohammadi has evaluated the single‐constant simplification for modeling artist paints; they have used both the hybrid and paint approaches. Thus, it was of interest to review these different approaches and determine whether these differences have practical importance and whether future printings and editions of Principles of Color Technology should be modified. The three approaches were tested for tints made from a mixture of cobalt blue and titanium white acrylic emulsion artist paints. The differences between the textile and hybrid approaches were inconsequential. The paint approach was superior and its use is recommended for opaque paint systems. The differences in the numerical example from Principles of Color Technology were very small. For future printings of the third edition, the example will remain unchanged. For future editions, including the numerical example remains an open question. © 2007 Wiley Periodicals, Inc. Col Res Appl, 32, 201–207, 2007
Camera color gamut: Spray‐painting the invisible definition
Authors: Brill Michael H. 
Published: April 2007

AbstractInspired by the recent article by Martinez‐Verdú et al., this note urges the explicit adoption of a definition for the camera color gamut. A viable definition seems to be the det of CIE XYZ triplets such that, for any such XYZ, there exists a spectral power distribution in a predefined set whose camera values map through a predefined algorithm to that XYZ. © 2007 Wiley Periodicals, Inc.

Analysis of cross‐cultural color emotion

Published: April 2007

AbstractThis study investigates the relationship between color perceptual attributes and color emotions, as well as the influence of different cultural backgrounds. Totally 214 color samples were evaluated on 12 emotion variables by subjects from seven different region groups in the psychophysical experiment. By factor analysis, it was found that three factors were sufficient to represent 80 “region‐emotion” variables. For each variable, there is no distinct difference among different region groups. The 12 emotion variables could be divided into four categories, namely, activity index, potency index, definition index, and temperature index. Factor scores were further calculated to study the determinants on each factor. The analysis showed that the three factors were mainly related to chroma, lightness, and hue, respectively. It was concluded that chroma and lightness were the most important factors on color emotion, whereas the influences of hue and cultural background were very limited. © 2007 Wiley Periodicals, Inc.

The financial performance of the FTSE4Good indices
Authors: Collison David J. , Cobb George , Power David M. , Stevenson Lorna A. 
Published: April 2007

AbstractThis paper examines the financial performance of the FTSE4Good indices; the indices include companies from different geographical areas on the basis of pre‐determined social responsibility criteria: currently environmental sustainability, relationships with stakeholders, attitudes to human rights, supply chain labour standards and the countering of bribery. The results indicate that over the period of analysis from 1996 to 2005 these indices outperformed their relevant benchmarks. However, most of this outperformance was due to risk differences between the FTSE4Good indices and their benchmarks. In addition, much of the outperformance arose in the period before the indices could be used by practitioners. Nevertheless, the results suggest that investors who invest in a portfolio of companies that satisfy FTSE4Good's corporate social responsibility criteria do no worse than their counterparts who do not follow a socially responsible strategy when purchasing equities.
