This book began as lecture notes for an Oregon State University course in fluid mechanics, designed for beginning graduate students in physical oceanography. Because of its fundamental nature, this course is often taken by students outside physical oceanography, e.g., atmospheric science, civil engineering, physics and mathematics.
In later courses, the student will discover esoteric fluid phenomena such as internal waves that propagate through the sky, water phase changes that govern clouds, and planetary rotation effects that control large-scale winds and ocean currents. In contrast, this course concerns phenomena that we have all been familiar with since childhood: flows you see in sinks and bathtubs, in rivers, and at the beach. In this context, we develop the mathematical techniques and scientific reasoning skills needed for higher-level courses and professional research. Prerequisites are few: basic linear algebra, differential and integral calculus and Newton’s laws of motion. As we go along we discover the need for the more advanced tools of tensor analysis.

In this volume, Erika Allen Wolters and Brent Steel have brought together the experts who can explain the evolution of public lands policies and politics in all their complexities. While their subject is complex, their prose is clear, and while their subject is torn by some of the most viciously self-interested, deceitful arguments in politics today, their prose is calm, factual, and evenhanded. No one should underestimate what a rare and valuable gift this is.

In this expanded new edition of Living with Earthquakes, Robert Yeats, a leading authority on earthquakes in California and the Pacific Northwest, describes the threat posed by the Cascadia Subduction Zone, a great earthquake fault which runs for hundreds of miles offshore from British Columbia to northern California. New research reveals subtle movements on the deepest part of this fault every 14-15 months — building up strain toward the next major earthquake.

Combining cutting-edge research with practical safety information, Living with Earthquakes:

• introduces new information about the danger from faults beneath major Northwest cities: the Seattle Fault, Tacoma Fault, and Portland Hills Fault
• explores such topics as earthquake forecasting, catastrophe insurance, tsunamis, soil liquefaction, and seismic waves in Northwest lakes caused by Alaskan earthquakes
• reviews earthquake preparedness and disaster response in the aftermath of the 2001 Nisqually earthquake, the worst natural disaster in Washington's history
• suggests actions that citizens can take to protect their families and homes
An essential guide for anyone interested in understanding earthquake science or in preparing for the next earthquake, this book is also a call to action. Vivid descriptions of recent disasters — including the great tsunami that swept down the Northwest coast in 1964, the 1993 Oregon earthquakes, and the 2001 Nisqually earthquake — underscore the urgent need for better earthquake planning and awareness.

In this textbook the focus will be on the bacteria and archaea (traditionally known as the “prokaryotes,”) and the viruses and other acellular agents.

This edited volume brings together a number of articles and books written on the subject of nuclear security to provide the reader with a broad and deep understanding of the many issues that surround the subject. It is divided into three parts, covering the challenges associated with nuclear security as it pertains to countries, non-state actors/terrorism, and civilian nuclear facilities. Each of these areas poses its own unique problems and challenges.

This module by Andrew Millison focusses on farm-scale water systems, and goes in depth into the Permaculture and Keyline strategies for managing water in the landscape for agricultural applications: ponds, roads, trees and soils. The module consists of a YouTube video playlist, a case study example and quiz, and a page of resources. The content has no deadline, and will remain up online indefinitely, so take your time browsing the 24 videos that make up the bulk of the teachings.
