Genetic Status of Atlantic Salmon in Maine
This interim report from the National Research Council's (NRC) Committee on Atlantic Salmon in Maine is a prepublication of the March 2002 report provided by National Academy Press. The once abundant populations of Atlantic Salmon in Maine have declined in recent years, now listed as endangered. The NRC Committee believes that "understanding the genetic makeup of Maine's salmon is important for recovery efforts." This 48-page report includes information on the salmon's biology, evolution, geneti

Rocket Me into Space
One of the exciting challenges for engineers is the idea of exploration. This lesson looks more closely at Spaceman Rohan, Spacewoman Tess, their daughter Maya, and their challenges with getting to space, setting up satellites, and exploring uncharted waters via a canoe. This lesson reinforces rockets as a vehicle that helps us explore outside the Earth’s atmosphere (that is, to move without air) by using the principles of Newton’s third law of motion. Also, the ideas of thrust, control and
Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.
Graphing the Rainbow
Students are introduced to different ways of displaying visual spectra, including colored “barcode” spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction grating acts like a prism, bending light into its component colors.
Engineering for the Earth
Young students are introduced to the complex systems of the Earth through numerous lessons on the Earth’s natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural resources, weather patterns and climatic regions, wind, erosion, landforms, and the harvesting of fossil fuels — all presented from an engineering point-of-view. (See the Unit Overview section for a list of topics by lesson.) Through many hands-on ac
Media, speech act theory and computer supported cooperative work
Speech act theory, an influential trend in current CSCW research, has been used tomodel and develop a number of academic and commercial groupware systems.The question remains, however, concerning what happens when we use speech acttheory to analyze real world conversations in an organizational context. Thisdissertation recorded the face-to-face and telephone conversations and collectedemail over a six week period of a real world group of computer scientistscollaborating to produce a complex piec
In Search of Cyrus The Great: Babylon
This 11:32 video is the dramatic story of the take over of of Babylon and its reaction to his victory over them. This is an excellent overview of the Founder of the Persian Empire.
Spiny Seahorse--An Overview
This short video gives excellent real life, close up footage of a Spiny Seahorse. Students will enjoy seeing this fascinating creature in its natural environment. Named after the spines that project from the corners of the bony plates covering the body, the spiny seahorse (Hippocampus histrix) is, like all seahorses, an intriguing and peculiar-looking fish. As well as its spiny appearance, this seahorse can be distinguished by its very long snout, which is sparsely patterned with white bars
Ohio Valley Natural Fibers
Located in Sardinia, it's the largest full-scale woolen mill in Ohio and
possibly the entire country. Its custom processed fleece is used for
quilts, batting, knitting and much more.
Monica Visinsky Interview
NASA Public Affairs Officer Brandi Dean talks with Monica Visinsky, the test coordinator for the Japanese Experiment Module ORU Transfer Interface. NASA is testing an airlock transfer device to pass orbital replacement units to and from Dextre, the robotic handyman on the exterior of the International Space Station.
Exploring Drawing Materials
Lesson encouraging children to explore a range of drawing materials and to discover the types of lines which can be made using them.
Multiple Sclerosis - Cranial Nerves Exam - Oculomotor, Trochlear, Abducens (CN III, IV, VI) Sub-exam
Janie is a 39-year-old Caucasian female who initially presented with weakness and L'Hermitte’s phenomena at the age of 35. Initially mistaken as a TIA, MRI of the brain revealed numerous plaques in the white matter suggesting Multiple Sclerosis. Her lumbar puncture initially failed to demonstrate the presence of oligoclonal bands, but since progression of the disease over the past few years bands have developed.
What is Special About Language?
Noam Chomsky, a world-renowned linguist, intellectual and political activist lectured at the University of Arizona on Feb. 7, 2012, on "What is Special About Language?" Noam Chomsky is an Institute Professor and a Professor Emeritus in the Department of Linguistics and Philosophy at Massachusetts Institute of Technology, where he worked for more than 50 years. Chomsky, who according to The New York Times is "arguably the most important intellectual alive," is credited with revolutionizing the
SMU Research Day 2012
SMU graduate students — and a limited number of undergraduates — present results of research they have completed at SMU at the annual Graduate Student Research Day. This year's event was held Friday, February 10, 2012, in the Ballroom of Hughes-Trigg Student Center. The aims of this event are to foster communication between students in different programs, give students the opportunity to present their work in formats they will use as professionals, and share with the SMU community and othe
This Week @Minnesota: Gopher Basketball, Safer Sex Week, & Vet Diagnostic Lab
This episode of This Week @ Minnesota features highlights from the Men's Gopher Basketball game, SHADE's Safer Sex Week, and the U's Veterinary Diagnostic Lab, which made national headlines in identifying the cause of death of a pigeon.
Systems Engineering, policy analysis and Management
In everyday life, private and public organisations are confronted with new technology developments, new business opportunities and societal changes presenting endless opportunities. To take advantage of these opportunities they need effective management strategies and system engineering approaches that deal with both technological complexity and the management of stakeholders with widely diverging interests. The Master's Programme in SEPAM gives students the ability to solve large-scale and com
Coordination Exam: Normal Exam: Check Reflex
Examiner pulls on actively flexed arm then suddenly releases. The patient should be able to check or stop the arm's movement when released. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how structure relates to function of the nervous system. The neurologic examination permits "dissection" of the nervous system and localizes the disease when present. Instead of simply memorizing the components of the ex
Coordination Exam: Anatomy: Exam Tests
The following tests of the neuro exam can be divided according to which system of the cerebellum is being examined: Vestibulocerebellum and spinocerebellum (midline): - Station - Walking - Tandem gait Cerebrocerebellum (appendicular): - Rapid alternating movements - Finger-to-nose - Toe-to-finger - Heel-to-shin - Rebound and check reflex – Speech. The first principle of neurologic diagnosis is regional or anatomical localization. In order to become skillful the student must understand how stru
