Plants as sessile organisms have evolved fascinating capacities to adapt to changes in their natural environment. Arguably, light is by far the most important and variable environmental factor. The quality, quantity, direction and duration of light is monitored by a series of photoreceptors covering spectral information from UVB to near infrared. The response of the plants to light is called photomorphogenesis and it is regulated by the concerted action of photoreceptors. The combined techniques of action spectroscopy and biochemistry allowed one of the important photoreceptors – phytochrome – to be identified in the middle of the last century. An enormous number of physiological studies published in the last century describe the properties of phytochrome and its function and also the physiology of blue and UV-B photoreceptors, unidentified at the time. This knowledge was summarized in the advanced textbook “Photomorphogenesis in Plants” (Kendrick and Kronenberg, eds., 1986, 1994). With the advent of molecular biology, genetics and new molecular, cellular techniques, our knowledge in the field of photomorphogenesis has dramatically increased over the last 15 years.
This timely book examines the field of European and global standardisation, showing how standards give rise to a multitude of different legal questions. It explores diverse topics in regulation such as food safety, accounting, telecommunications and medical devices. Each chapter offers in-depth analysis of a number of key policy areas. These multi-disciplinary contributions go beyond the field of law, and provide cross-disciplinary comparisons.
Inhaltsangabe:Introduction: These days a current newspaper without an article in the business section covering the issue of globalization and the effects involved is unthinkable. Due to that fact, cultural diversity is often mentioned, and its presence within the media grows increasingly as does its value within our society as well as in our policies and economy. The globalization of markets and companies has been the driving force of change over the past decade. Its process affects every nation worldwide and represents a challenge because worldwide competition between national economies is engendering and the degree of international intertwining is increasing.Consequently, the current trend...
Social surveillance and regulation of knowledge will be one of the most important issues in the near future, one that will give rise to unending controversy. In The Governance of Knowledge, Nico Stehr predicts that such concerns will create a new political field, namely, knowledge policy, which will entail regulating dissemination of the anticipated results of rapidly increasing knowledge. The number and range of institutionalized standards for monitoring new knowledge has hitherto been relatively small. Only in cases of technological applications has social control, in the form of political regulation, so far intervened. All modern societies today have complex regulations and extensive conc...
Ed Spade und Phil Garner sind zwei Privatermittler, die ihren Lebensunterhalt mehr schlecht als recht in der US-Metropole New Guessgrow City verdienen. Obwohl sie von ihren hübschen Sekretärinnen Brenda und Linda tatkräftig unterstützt werden, ist ihr Alltag nicht nur von chronischem Geld- und Klientenmangel geprägt, sondern vor allem von ihrer Begabung, sich immer wieder in ebenso groteske wie gefährliche Situationen zu bringen. Einst waren sie beste Freunde und Partner, doch ihr Verhältnis hat sich nach einem länger zurückliegenden Streit deutlich abgekühlt, und jeder geht seither seinen eigenen Weg. Zu Beginn des Jahres 1954 erhalten sie unabhängig voneinander einen höchst sku...
Mitten in Terrania, der Hauptstadt der Erde, wächst eine gigantische Stele aus dem Nichts. Sie spukt einen geheimnisvollen Mann aus, der sich Peregrin nennt. Er weist der Menschheit den Weg zu einer neuen Bedrohung – Perry Rhodan muss zu den Magellanschen Wolken aufbrechen, den rund 200.000 Lichtjahre von der Erde entfernten Zwerggalaxien. Rhodan reist mit der SOL, dem mächtigsten Raumschiff der Menschheit. Am Rand der Galaxis stoßen die Menschen auf den Chronopuls-Wall, eine Barriere aus Sternen und Zeit. Sie soll die Milchstraße vor einer bislang unbekannten Gefahr beschützen. Der mysteriöse Peregrin erweist sich als Gesandter einer fremden Macht. Im Zentrum der Großen Magellanschen Wolke wartet seine scheinbar unüberwindliche BURG. Wird sie von den falschen Kräften aktiviert, ist alles verloren ...
On February 5, 1890, the First District Royal Court of Prussia in Berlin entered a new enter prise into the corporate trade register: the „Allianz Versicherungs-Aktien-Gesellschaft“. 125 years later, Allianz is one of the largest international financial services prividers. This book tells the story of the company’s history in a lucidandent ertaining way. Even before the First World War, Allianz had entered the international insurance industry. But the two World Warsde stroy edits early attempts at global expansion. Not until the 1980s was Allianz able to reach the same degree of internationalization it had already achieved before 1914, breaking through to become a global insurer. Since...
