Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. - Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales - Covers plant anatomy: an essential component to understanding soil and plant water relations

A fresh look at two centuries of humanitarian history through a moral economy approach focusing on appeals, allocation, and accounting.

"My aim in it has been to convey a juster and less prejudiced notion than prevails at present respecting the Danish and Norwegian conquests." -Jens Jacob Asmussen Worsaae, An Account of the Danes and the Norwegians (1852) An Account of the Danes and the Norwegians in England, Scotland and Ireland (1852) by Jens Warsaae, was based on his research into the Scandinavian invasions of the European mainland. During the 10th century, the European mainland was invaded by Norse settlers from Denmark, Norway, and Sweden, who intermarried with native tribes and came to be known as "Normans." While their influence on the history of France was significant, it was even stronger in England, which the Normans conquered in the 11th century. Warsaae's book, commissioned by the Royal Society of Northern Antiquaries, was his attempt to revise the impressions that the 19th century British had of the effects of the Norman conquests on England.
