Helps you equip you with the inspiration and knowledge you need to make a difference solving environmental issues.

Designed to equip students with the inspiration and knowledge they need to make a difference solving environmental issues, this book provides introductions to the multiple environmental problems that we face and balanced discussions to evaluate potential solutions.

Striking a balance between theory and practice, this graduate-level text is perfect for students in the applied sciences. The author provides a clear introduction to the classical methods, how they work and why they sometimes fail. Crucially, he also demonstrates how these simple and classical techniques can be combined to address difficult problems. Many worked examples and sample programs are provided to help the reader make practical use of the subject material. Further mathematical background, if required, is summarized in an appendix. Topics covered include classical methods for linear systems, eigenvalues, interpolation and integration, ODEs and data fitting, and also more modern ideas like adaptivity and stochastic differential equations.

The objectives of this project were to develop (1) a better understanding of the effects of storage on reclaimed water quality, (2) a methodology to help understand/predict water quality changes during storage, and (3) effective management tools for minimizing water quality problems. The research team reviewed approximately 120 published articles, conducted a gray literature survey to analyze the impact of surface storage on reclaimed water quality. The team also evaluated federal guidelines for reclaimed water and developed a brief update on what individual states are doing. It was determined that state and federal water quality objectives can be met at the treatment site. However, because of the seasonal nature of reclaimed water use, water often must be stored in open reservoirs, where changes occur that can affect water quality. The nature of these changes was evaluated, including physical, chemical, and biological processes. The research team evaluated several reservoir management strategies to improve water quality, and reviewed water quality models to assess their applicability for open reclaimed water storage reservoirs. It also developed procedures to evaluate and select management strategies and reservoir water, along with matrices to distill the information learned in the study into a useful format for risk assessors and water quality managers. These tools will enable users to readily equate their specific storage reservoirs to representative examples, and to identify actions most applicable to their specific reclaimed water systems.

Achilla Johnson doesn't know her father. Her mother, Ailina Harris, tells her that he is a rich lawyer who pays for his new family but ignores her. She tells Achilla that she is superior to everyone, including him, and that she should use her special abilities to lord over the weak. Achilla believes her until Brendan Johnson takes her in, and she finds out that everything Ailina says about him is a lie. Achilla learns that there is more to the world, her father, and herself than what her mother has taught her. There is also a lot more to Ailina than she could have ever prepared for. Achilla must choose a side, and both come with a heavy price. With all of her power, Achilla doesn't know if she is strong enough to bear the weight of her decision and the fight that it brings. If she loses, Achilla and Brendan may not live to regret her choice. Achilla the Strong is the first novel of The Nephilim Chronicles.

A practical handbook on the analysis of foods for pesticide residue contamination. Its ultimate aim is to assure that a food control laboratory produces high quality analytical results using analytical methodology which has been shown to be reliable and reproducible for pesticide residue analyses.
