Endospore-forming Soil Bacteria
Aerobic endospore-forming bacteria are found in soils of all kinds, ranging from acid to alkaline, hot to cold, and fertile to desert. It is well known that endospores confer special properties upon their owners and play dominant parts in their life cycles and dispersal, and much has been written about the spores, genetics, and economic importance of these organisms. Much has also been written about soil ecology, but there is a relative dearth of literature that brings together different aspects of the behaviour and characters of endospore-formers with their contributions to soil ecosystems. This Soil Biology volume fills that gap. Following chapters that describe the current classification of these organisms, that review methods for their detection and for studying their life cycles in soils, and that examine their dispersal, other chapters show that they are active and dynamic members of soil floras that interact widely with other soil inhabitants, with roles in nitrogen fixation, denitrification, and soil remediation.
Spatial Modeling and Assessment of Environmental Contaminants
This book demonstrates the measurement, monitoring and mapping of environmental contaminants in soil & sediment, surface & groundwater and atmosphere. This book explores state-of-art techniques based on methodological and modeling in modern geospatial techniques specifically focusing on the recent trends in data mining techniques and robust modeling. It also presents modifications of and improvements to existing control technologies for remediation of environmental contaminants. In addition, it includes three separate sections on contaminants, risk assessment and remediation of different existing and emerging pollutants. It covers major topics such as: Radioactive Wastes, Solid and Hazardous Wastes, Heavy Metal Contaminants, Arsenic Contaminants, Microplastic Pollution, Microbiology of Soil and Sediments, Soil Salinity and Sodicity, Aquatic Ecotoxicity Assessment, Fluoride Contamination, Hydrochemistry, Geochemistry, Indoor Pollution and Human Health aspects. The content of this book will be of interest to researchers, professionals, and policymakers whose work involves environmental contaminants and related solutions.
Ethnicity, Gender and Social Change
Ethnicity, Gender and Social Change explores the social space occupied by both gender and ethnicity. As recognition of the sociological importance of gender and ethnicity has grown, so has the opportunity for exploring the intersections between them. This volume brings together both theoretical reflections and new research in this key area. For the sociologist this presents a conceptual challenge, while for the individual it may present a series of dilemmas. These are intriguingly traced out in studies which take us from Punjabi families in the UK, to Surinamese migrants in Amsterdam, to Hindu and Muslim women and Black nurses in Britain, the African and Asian diasporas, and gender identity in post-Soviet Latvia.

The Last Good Man
“A truly compelling and worthwhile thriller” (Associated Press) that centers around the mysterious murders of humanitarian men and women and the detective who seeks to solve the riddle—before it’s too late. In Beijing, a monk collapses in his chamber , dead. A fiery mark—a tattoo? a burn?—spreads across his back and down his spine. In Mumbai, a beloved economist dies suddenly. The same symbol appears. Similar deaths are reported around the world—the victims all humanitarians, all with the same death mark. In Venice, a rogue Italian policeman links the deaths, tracing the evidence. Who is killing good people around the world? In Copenhagen, the Interpol alert lands on the desk o...
Bacillus thuringiensis Biotechnology
Bacillus thuringiensis (Bt) has been used as a biopesticide in agriculture, forestry and mosquito control because of its advantages of specific toxicity against target insects, lack of polluting residues and safety to non-target organisms. The insecticidal properties of this bacterium are due to insecticidal proteins produced during sporulation. Despite these ecological benefits, the use of Bt biopesticides has lagged behind the synthetic chemicals. Genetic improvement of Bt natural strains, in particular Bt recombination, offers a promising means of improving efficacy and cost-effectiveness of Bt-based bioinsecticide products to develop new biotechnological applications. On the other hand, ...
