This SpringerBrief on Spx reviews the investigations that led to the discovery of Spx and its orthologs and ties together the results of various studies that have explored the function and control of spx in Gram-positive organisms. Spx of Bacillus subtilis has been extensively studied, but very little has been published about it. This book incorporates a number of studies that have been conducted in other Gram positive bacteria, which examined the role of Spx orthologs in stress response, bacterial development and virulence.

The book contains an overview that...

Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work.

The conversion of bio-mass into high value...

Sustainable groundwater development requires knowledge of the appropriate recharge and transport-processes. This is a prerequisite to understanding: (i) groundwater resources and their availability, and (ii) the dependence between groundwater and the environment. Conceptual understanding of groundwater flow at both temporal and spatial scales (local and regional) is essential for management that will support engineering, industry, agriculture, ecology, and all environmentally related issues.

This book has been prepared for scientists, researchers, students, engineers, water...

Almost a century and a half went into the making of My Eighty Years in Texas. It began as a diary, kept by fifteen-year-old William Physick Zuber after he joined Sam Houston's Texas army in 1836, hoping he could emulate the heroism of American Revolutionary patriots. Although his hopes were never realized, Zuber recorded the privations, victories, and defeats of armies on the move during the Texas Revolution, the Indian campaigns, and, as he styled it, the Confederate War.

In 1910, at the age of ninety, Zuber began the enormous task of transcribing his diaries and his...
