Flowering Plants
Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.
The missing woodland resources
Woodlands are a key source of raw materials for many purposes since early Prehistory. Wood, bark, resin, leaves, fibers, fungi, moss, or tubers have been gathered to fulfill almost every human need. That led societies to develop specific technologies to acquire, manage, transform, elaborate, use, and consume these resources. The materials provided by woodlands covered a wide range of necessities such as food, shelter, clothing, or tool production, but they also provided resources employed for waterproofing, dying, medicine, and adhesives, among many others. All these technological processes and uses are commonly difficult to identify through the archaeological record. Some materials are excl...
Oregano
Oregano: The Genera Origanum and Lippia is an updated analysis of the technical knowledge and market information on the world's most commercially valuable spice. The book treats various aspects of practical significance for the crop's industrialization, such as optimizing germplasm selection and utilization, novel cultivation methods and product pr
Flowering Plants · Dicotyledons
In this volume, 24 flowering plant families comprising a total of 911 genera are treated. They represent the asterid order Lamiales except for Acanthaceae (including Avicenniaceae), which will be included in a later volume. Although most of the constituent families of the order have been recognized as being closely related long ago, the inclusion of the families Byblidaceae, Carlemanniaceae and Plocospermataceae is the result mainly of recent molecular systematic research. Keys for the identification of all genera are provided, and likely phylogenetic relationships are discussed extensively. To facilitate the recognition of relationships, families are cross-referenced where necessary. The wealth of information contained in this volume makes it an indispensable source for anybody in the fields of pure and applied plant sciences.

Artificial Intelligence in Education
This book constitutes the refereed proceedings of the 16th International Conference on Artificial Intelligence in Education, AIED 2013, held in Memphis, TN, USA in July 2013. The 55 revised full papers presented together with 73 poster presentations were carefully reviewed and selected from a total of 168 submissions. The papers are arranged in sessions on student modeling and personalization, open-learner modeling, affective computing and engagement, educational data mining, learning together (collaborative learning and social computing), natural language processing, pedagogical agents, metacognition and self-regulated learning, feedback and scaffolding, designed learning activities, educational games and narrative, and outreach and scaling up.
Persistent Spectral Hole-Burning: Science and Applications
Almost fifteen years have now elapsed since the first observations of per sistent spectral hole-burning in inhomogeneously broadened absorption lines in solids. The fact that the spectral shape of an inhomogeneously broadened line can be locally modified for long periods of time has led to a large number of investigations of low-temperature photophysics and photochemistry that would not have been possible otherwise. Using hole burning, important information has been obtained about a variety of in teractions, including excited-state dephasing processes, host-guest dynam ics, proton tunnelling, low-frequency excitation in amorphous hosts, relaxation mechanisms for vibrational modes, photochemi...
