Ancient Syria: A Three Thousand Year History

Ancient Syria: A Three Thousand Year History by Trevor Bryce
2014 | ISBN: 0199646678 | English | 400 pages | PDF | 9 MB
Syria has long been one of the most trouble-prone and politically volatile regions of the Near and Middle Eastern world. This book looks back beyond the troubles of the present to tell the 3000-year story of what came before: the peoples, cities, and kingdoms that arose, flourished, declined, and disappeared in the lands that now constitute Syria, from the time of the region's earliest written records in the third millennium BC, right through to the reign of the Roman emperor Diocletian in the early 4th century AD.

Across the centuries, from the Bronze Age to Imperial Rome, we encounter a vast array of characters and civilizations, enlivening, enriching, and besmirching the annals of Syrian history: Hittite and Assyrian Great Kings; Egyptian pharaohs; Amorite robber-barons; the biblically notorious Nebuchadnezzar; Persia's Cyrus the Great and Macedon's Alexander the Great; the rulers of the Seleucid empire; and an assortment of Rome's most distinguished and most infamous emperors. All swept across the plains of Syria at some point in her long history. All contributed, in one way or another, to Syria's special, distinctive character, as they imposed themselves upon it, fought one another within it, or pillaged their way through it.

But this is not just a history of invasion and oppression. Syria had great rulers of her own, native-born Syrian luminaries, sometimes appearing as local champions who sought to liberate their lands from foreign despots, sometimes as cunning, self-seeking manipulators of squabbles between their overlords. They culminate with Zenobia, Queen of Palmyra, whose life provides a fitting grand finale to the first three millennia of this ancient civilization. And yet the long story of Syria does not end with the mysterious fate of Queen Zenobia. The conclusion looks forward to the Muslim conquest in the 7th century AD: in many ways the opening chapter in the equally complex and often troubled history of modern Syria.

Abiotic Stress Responses in Plants: Metabolism, Productivity and Sustainability

Parvaiz Ahmad, M.N.V. Prasad – Abiotic Stress Responses in Plants: Metabolism, Productivity and Sustainability
Published: 2011-11-18 | ISBN: 1461406331 | PDF | 627 pages | 7 MB

Abiotic stress cause changes in soil-plant-atmosphere continuum and is responsible for reduced yield in several major crops. Therefore, the subject of abiotic stress response in plants – metabolism, productivity and sustainability – is gaining considerable significance in the contemporary world. Abiotic stress is an integral part of “climate change,” a complex phenomenon with a wide range of unpredictable impacts on the environment. Prolonged exposure to these abiotic stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to tolerate these stresses by upregulation of osmolytes, osmoprotectants, and enzymatic and non-enzymatic antioxidants, etc. This volume deals with abiotic stress-induced morphological and anatomical changes, abberations in metabolism, strategies and approaches to increase salt tolerance, managing the drought stress, sustainable fruit production and postharvest stress treatments, role of glutathione reductase, flavonoids as antioxidants in plants, the role of salicylic acid and trehalose in plants, stress-induced flowering. The role of soil organic matter in mineral nutrition and fatty acid profile in response to heavy metal stress are also dealt with. Proteomic markers for oxidative stress as a new tools for reactive oxygen species and photosynthesis research, abscisic acid signaling in plants are covered with chosen examples. Stress responsive genes and gene products including expressed proteins that are implicated in conferring tolerance to the plant are presented. Thus, this volume would provides the reader with a wide spectrum of information including key references and with a large number of illustrations and tables.
