Geochemical Techniques for Identifying Sources of Ground-Water Salinization offers a comprehensive look at the threat to the United States' freshwater resources due to salinization and outlines techniques that can be used to study the problem. The book reviews the seven major salt-water sources that commonly mix and deteriorate our fresh ground water (natural saline ground water, halite solution, sea-water intrusion, oil- and gas-field brines, agriculture effluents, saline seep, and road salting). Other topics covered are the characteristics of saltwater sources, geochemical parameters, and basic graphical and statistical methods that are frequently used in saltwater studies. The book also provides geographical charts showing the distribution of the major salt-water sources, illustrating which ones are potential sources in any given area in the United States.Geochemical Techniques for Identifying Sources of Ground-Water Salinization describes the individual geochemical parameters used in identifying salinization and the information on how and where to obtain them. This is an informative book for anyone interested in the present and future quality of our fresh-water supply.
Our planet is currently experiencing substantial changes due to natural phen- ena and direct or indirect human interactions. Observations from space are the only means to monitor and quantify these changes on a global and long-term p- spective. Continuous time series of a large set of Earth system parameters are needed in order to better understand the processes causing these changes, as well as their interactions. This knowledge is needed to build comprehensive Earth s- tem models used for analysis and prediction of the changing Earth. Geodesy and geophysics contribute to the understanding of system Earth through the observation of global parameter sets in space and time, such as tectonic m...
This book presents an interdisciplinary collection of expert analyses and views of existing verification systems. It provides guidelines and advice for the improvement of those systems as well as for new challenges in the field.
Internationally recognized experts, pioneers, and opinion makers in evidence-based medicine (EBM) provocatively recast endocrine policy and practice in the light of EBM philosophy and principles. The authors explain the past, present, and future of EBM; consider its practical implications for endocrinology; demonstrate what the "evidence base" is in EBM; and present illustrative case studies by practicing evidence-based clinicians. Highlights include essays on why cost-effective analyses are problematic, the contrast between clinical investigations and large randomized trials, the role of Cochrane reviews and meta-analyses, and the curriculum requirements for training evidence-based endocrinologists.
Evidence-Based Ophthalmology offers a unique approach to managing eye disease. From systematic reviewing of evidence, this book provides an overview of techniques for optimum management in key areas, including glaucoma, cataract and retinal disease – an invaluable reference source for practitioners worldwide representing an important contribution to the literature. Key Features International authorship by leading Cochrane participants An unbiased method for summarising and disseminating the evidence Identifies gaps in evidence, and therefore research opportunities Free-access update website giving the latest trial data and recommendations for implementation in practice Includes a free fully searchable CD-ROM
We fear what we don't know. No matter what country or culture we come from or what color our skin is, we all have this primal fear of the unknown. This diffuse fear that we share is also the thing that separates us from one another. Hardly any other topic is as charged with such controversy, polarization, doubt and inhibitions as the topic of integration. With her book, 47 magical ways locals and non-locals meet each other, Susan Omondi sets out to overcome the rifts that divide us. Profound, touching and always humorous, the Kenyan-born author tells stories from her everyday life, raises awareness of racism and sheds light on the perspectives of both immigrants or "non-locals" and locals. As an author, keynote speaker, moderator and trainer, Omondi's main focus is on diversity in the workplace and the great professional and human opportunities that come with overcoming our fears and prejudices. She lives out the motto: "When we engage with one another, magic happens".
In the recent years, space-based observation methods have led to a subst- tially improved understanding of Earth system. Geodesy and geophysics are contributing to this development by measuring the temporal and spatial va- ations of the Earth’s shape, gravity ?eld, and magnetic ?eld, as well as at- sphere density. In the frame of the GermanR&D programmeGEOTECHNO- LOGIEN,researchprojectshavebeen launchedin2002relatedto the satellite missions CHAMP, GRACE and ESA’s planned mission GOCE, to comp- mentary terrestrial and airborne sensor systems and to consistent and stable high-precision global reference systems for satellite and other techniques. In the initial 3-year phase of the research ...
Reckonings documents how Holocaust victims have sought justice over the decades and the haunting disparity between crime and punishment.
The Transactions XXVIIA Reports on Astronomy 2006-2009 provides a comprehensive and authoritative review of what has been achieved in astronomy during the years 2006 to 2009. These insightful and up-to-date reviews have been written by the presidents and chairpersons of the IAU scientific bodies: the Divisions, the Commissions, and the Working Groups. Topics covered in this wide-ranging volume include: fundamental astronomy; the Sun and heliosphere; planetary sciences; stars; variable stars; interstellar matter; the Galactic system; galaxies and the Universe; optical and infrared techniques; radio astronomy; space and high-energy astrophysics; and other IAU activities. The reviews have been written at a level suitable for colleagues in the same fields, but will also be useful for students and researchers wishing to gain an overview of astronomical fields beyond their own research area.
