The importance of the kidneys is most clearly demonstrated in the presence of pathophysiologic states. The kidneys play a central role in the maintenance of the internal milieu by balancing fluid, electrolytes, and hydrogen ions to provide optimal conditions for molecular, cellular, and body system function. They also serve as the major excretory organ for metabolic byproducts, drugs, and other organic substances. Finally, the kidneys are an important endocrine organ, producing vasoactive factor
Introduction to Clinical Pain Problems
Research of the mechanisms, nature, and treatment of pain has advanced enormously in the past decade. Introduction to Clinical Pain Problems is part of the Tufts University School of Medicine Master of Science in Pain Research, Education and Policy program. The program, founded in 1999 by an anesthesiology/internist and a sociologist, meets the needs of practicing health care professionals to provide optimal pain management by offering a unique, interdisciplinary program that sets the standard f
Force and Strategy
This course examines the political, economic,military, and ethical factors affecting the use and utility of military force in international relations. Students will study the political and decision-making process by which nations decide to use military force as well as the major arms control agreements of the post-World War II period, including negotiations currently under way.
The Introduction to Cardiovascular Pathophysiology course provides the students with two main objectives. It delineates the material students are expected to understand and have recalled from the basic cardiac physiology lectures and it expands on the discussion of the hemodynamic perturbations of cardiac function.
Calculus on the Web
COW is an internet utility for learning and practicing calculus. The principal purpose of COW is to provide you, the student or interested user, with the opportunity to learn and practice problems in calculus (and in the future other topics in mathematics) in a friendly environment via the internet. The most important feature of the COW is that you get to know whether your answer is correct almost immediately. It is as if you had a tutor looking over your shoulder and helping you along as you wo
Story of Stuff International
From its extraction through sale, use and disposal, all the stuff in our lives affects communities at home and abroad, yet most of this is hidden from view. The Story of Stuff is a 20-minute, fast-paced, fact-filled look at the underside of our production and consumption patterns. The Story of Stuff exposes the connections between a huge number of environmental and social issues, and calls us together to create a more sustainable and just world. It'll teach you something, it'll make you laugh, a
Radioactive Decay Model
The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy. The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Bering Sea Climate
The Bering Sea Climate website contains time series data that measures climate and ecosystem status in the Bering Sea. The site presents data, metadata, and graphics by allowing the user to select categories and then click a button for the desired function. Data can be displayed as a list, a time series plot, or in terms of recent trends, relevance, and correlation. Measured parameters include weather, oceanographic and climate data, sea ice data, and fisheries and other biological data. The sit
