 Free Download Molecular Aspects of Iron Metabolism in Pathogenic and Symbiotic Plant-Microbe Associations By Dominique Expert (auth.), Dominique Expert, Mark R. O'Brian (eds.) 2012 | 86 Pages | ISBN: 9400752660 | PDF | 2 MB Iron plays a key role in biology as essential cofactor of numerous proteins. However, since it is only slightly soluble its bioavailability can be readily compromised under aerobic conditions. Moreover, due to its ability to catalyze the generation of free radicals, iron can also be toxic. Thus, it doesn't surprise that living organisms have developed sophisticated means for acquiring iron whilst tightly controlling the intracellular concentrations of this metal in response to environmental conditions. Also, the critical role of iron has long been acknowledged in host vertebrate-parasite relationships where both partners compete for the acquisition of this essential element and activate complex signaling cascades to control their iron homeostasis during infection. Following the great interest that the mechanisms regulating the acquisition of iron and the control of iron homeostasis have generated among researchers studying plant-pathogen and legume-rhizobia interactions, this book offers a comprehensive analysis of irons' various roles in the plant-microbial associations. The introductory chapter stresses the essentiality of iron in biological systems. The second chapter surveys the abundance of information on iron's pivotal role in microbial plant pathogenesis and defence. Finally, the third chapter reviews the advances in our understanding of iron metabolism in the rhizobia, soil bacteria able to establish a symbiotic association with legumes and carry out nitrogen fixation. Molecular Aspects of Iron Metabolism in Pathogenic and Symbiotic Plant-Microbe Associations is a valuable resource to microbiologists, pathologists and scientists interested in iron uptake and metabolism in microbial pathogenesis, rhizobia legume associations, and plant physiology and immunity.

Free Download Modern Origins: A North African Perspective By A. Moreno (auth.), Jean-Jacques Hublin, Shannon P. McPherron (eds.) 2012 | 246 Pages | ISBN: 9400729286 | PDF | 10 MB Over the last decade, Africa has taken a central position in the search for the timing and mechanisms leading to modern human origins, and the rich archaeological and human paleontological record of North Africa is critical to this search. In this volume, we bring together new research into the archaeology, human paleontology, chronology, and environmental context of modern human origins in North Africa. The result is a volume that better integrates the North African record into the modern human origins debate and at the same time highlights the research questions that are currently the focus of continued work in the area.
 Free Download Modern Concepts of the Theory of the Firm: Managing Enterprises of the New Economy By Horst Albach (auth.), Prof. Dr. Günter Fandel, Prof. Dr. Uschi Backes-Gellner, Dr. Manfred Schlüter, Dipl.-Kfm. Joerg E. Staufenbiel (eds.) 2004 | 648 Pages | ISBN: 3642073492 | PDF | 16 MB This volume contains the results of the International Conference on "Man aging Enterprises ofthe New Economy by Modem Concepts ofthe Theory ofthe Firm", which took place in Hagen from 12-14 December 2002. The conference was organised jointly by the FernUniversität in Hagen and the Erich-Gutenberg-Arbeitsgemeinschaft in Cologne. The Deutsche For schungsgemeinschaft, the FernUniversität and the Märkische Bank in Hagen provided generous financial support for the conference, and in fact enabled its implementation and the publication of this record of the pro ceedings. We would like to express our gratitude to the sponsors for their support. The aim of the conference was the exchange of academic experience with regard to new approaches to, and extensions of, the theory of the firm that can be used to solve the problems of New Economy companies. The starting point was the practical experience that the owners and managers of New Economy companies paid too little attention to functional company controls in the general euphoria regarding future economic trends and that because of this the enterprises got into difficulties or were faced with threats to their survival. These control deficits were detected equally in the areas of sales, production, personnel planning, organisation and finance and in the arrangement of management and control structures. Deficiencies in company evaluations and accounting led to investors experiencing se vere disappointment on the loss of their invested capital.  Free Download Modern Art and Modernism: A Critical Anthology edited by Charles Harrison, Francis Frascina English | March 2, 1983 | ISBN: 0064301249, 1853960322, 0367094800 | True PDF | 336 pages | 58.7 MB Modern Art and Modernism offers first-hand material for the study of issues central to the development of modern art, its theory and criticism. The history of modern art is not simply a history of works of art, it is also a history of ideas and interpretations. The works of critics and theorists have not merely been influential in deciding how modern art is to be seen and understood, they have also influenced the course it has taken. The nature of modern art cannot be understood without some analysis of the concept of Modernism itself.
 Free Download Models & Methods for Project Selection: Concepts from Management Science, Finance and Information Technology By Samuel B. Graves, Jeffrey L. Ringuest, Andrés L. Medaglia (auth.) 2003 | 193 Pages | ISBN: 1461350018 | PDF | 4 MB Models & Methods for Project Selection systematically examines in this book treatment the latest work in the field of project selection modeling. The models presented are drawn from mathematical programming, decision theory, and finance. These models are examined in two categorical streams: the management science stream and the financial model stream. The book describes the assumptions and limitations of each model and provides appropriate solution methodologies. Its organization follows three main themes: *Criteria for Choice: Chapters 1-3 investigate the effect of the choice of optimization criteria on the results of the portfolio optimization problem. *Risk and Uncertainty: Chapters 4-7 deal with uncertainty in the project selection problem. *Non-Linearity and Interdependence: These chapters deal with problems of non-linearity and interdependence as they arise in the project selection problem. Chapters 8, 9 and 10 present solution methodologies, which can be used to solve these most general project selection models.  Free Download Modellierung und Bewertung von Kreditrisiken By Peter Grundke (auth.) 2003 | 337 Pages | ISBN: 3824491117 | PDF | 8 MB Zur Bestimmung risikoadäquater Preise für ausfallbedrohte Finanztitel eignen sich Modelle, die unter der Annahme der Arbitragefreiheit eine präferenzfreie Bewertung ermöglichen. Allerdings weichen die bislang entwickelten Ansätze hinsichtlich der Bewertungsidee und des notwendigen Dateninputs von einander ab. Peter Grundke untersucht, inwieweit sich die Bewertungsergebnisse, die in den vorliegenden Modellansätzen generiert werden, in Bezug auf Höhe und Sensitivität gegenüber Einflussfaktoren unterscheiden. Ein weiterer Fokus liegt auf der Analyse ratingbasierter Bewertungsmodelle. Ausgehend von einem einfachen Grundmodell vergleicht der Verfasser Annahmen und Implikationen systematisch mit empirischen Befunden. Zur Überwindung konstatierter Defizite entwickelt er verschiedene realitätsnähere Modellvarianten. Zudem bewertet er zahlreiche Kreditderivatformen in einem ratingbasierten Modellkontext. Um die Unterschätzung unerwarteter Verluste eines Kreditportfolios zu vermeiden, verknüpft er darüber hinaus ratingbasierte Bewertungsmodelle mit im Risikomanagement verwendeten Kreditportfoliomodellen. |
