Exercise Physiology: The Response of Metabolic Rate to Physical Activity
In this lab, students measure their heart rate, oxygen consumption, and carbon dioxide production in various physical activities on a treadmill or cycle ergometer. After learning the techniques in the first lab period, each group of 3-4 students designs an independent investigation that is performed during the second lab period. To measure metabolic rate, students collect expired air in a Douglas bag, then measure the volume, the temperature, and the concentration of oxygen and carbon dioxide. W

"Quasi-Balanced Circulations in Oceans and Atmospheres, Fall 2009"
" This course introduces the students to dynamics of large-scale circulations in oceans and atmospheres. Basic concepts include mass and momentum conservation, hydrostatic and geostrophic balance, and pressure and other vertical coordinates. It covers the topics of fundamental conservation and balance principles for large-scale flow, generation and dissipation of quasi-balanced eddies, as well as equilibrated quasi-balanced systems. Examples of oceanic and atmospheric quasi-balanced flows, compu

Saturday Night on the Range: Rural Life in World War I Era Montana
We often like to imagine rural life in the past as timeless, "traditional," and in some way simpler and more authentic. Yet, rural life in the years around World War I, while sometimes recalled as simpler, could often seem very much like life anywhere else. In this interview, conducted by Laurie Mercier in 1982 for the Montana Historical Society, Tom Staff remembers how Montana farmers took other jobs to supplement their incomes. Here he described how the road crew he worked on left camp for dan

Introduction to Philosophy II
This course is designed as a "topics-based" introduction to philosophy. What this means is that instead of working through the history of philosophy focusing on great historical figures and their views on different topics, we will focus on great philosophical topics and look at what historical and contemporary writers have said about them. Topics to be addressed will include the existence of God, the relation between the mind and the body, human freedom, and the foundations of morality.

Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar

Wireless Sensor Networks for Ecology
Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals -- even multiple times per second -- over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively
