Collaborative Work During Interventional Radiological Procedures Based on a Multicast Satellite-Terr
Collaboration is a key requirement in several contemporary interventional radiology procedures (IRPs). This work proposes a multicast hybrid satellite system capable of supporting advanced IRP collaboration, and evaluates its feasibility and applicability. Following a detailed IRP requirements study, we have developed a system which supports IRP collaboration through the employment of a hybrid satellite-terrestrial network, a prototype multicast version of wavelet based interactive communication
Tonto National Monument: Saving a National Treasure
tells the story of the Salado people, who thrived in the Arizona valley where Tonto Creek joins the Salt River (1050-1450 AD). The Salado culture combined customs of several American Indian groups. They channeled the river to create farmland in the desert. They built Pueblo-style buildings. They left no written records. This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.
Slavery and Abolition
This site presents two dozen publications written in the 19th century about slavery in America. It includes first-person accounts from former slaves, judicial opinions, abolitionist pieces, and more.
The Thomas Jefferson Papers
The complete Thomas Jefferson Papers from the Manuscript Division at the Library of Congress consists of approximately 27,000 documents. This is the largest collection of original Jefferson documents in the world. Document types in the collection as a whole include correspondence, commonplace books, financial account books, and manuscript volumes. The collection is organized into ten series or groupings, ranging in date from 1606 to 1827. Correspondence, memoranda, notes, and drafts of documents
Large groups of children are likely to scare off mammals, but they can learn to identify tracks to learn more about the animals that left them.
What Can We Learn About Our Seasons?
The purpose of this resource is to have students develop a qualitative understanding of the characteristics and patterns of seasons and highlight the relationship of seasons to physical, biological and cultural markers. Students observe and record seasonal changes in their local study site. They establish that these phenomena follow annual cycles and conclude the activity by creating displays that illustrate the repeating pattern associated with the appearance and disappearance of seasonal marke
Seasonal Change on Land and Water
The purpose of this resource is to further students' understanding of the causes of seasonal change using visualizations to compare the effects of incoming solar energy in the two hemispheres. The class reviews global visualizations of incoming sunlight and surface temperature and discusses seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres, culminating in an evidence-based argument about why one hemi
GEOLogic: Museums and their Dinosaur Displays
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match five top museums with two fossils that they have on display based on clues presented from various points of view. This activity is appropriate for a high school science class or an introductory level undergraduate geoscience course, and can be given as an in-class assign
GEOLogic: How Much of the State is Wet
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up students with their home state, and their states with the area and percentage of area of surface water that they contain, as well as where each of the states rank nationally in terms of water area. Students are given clues from various perspectives to help them deduce
GEOLogic: Continental Drift and Plate Tectonics
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up lecturers with what day and time they teach, and how many students they have in each class based on clues given from several different perspectives. In the second part of the activity, students are asked to learn more about the historic figures mentioned by doing read
Conflict resolution: Working with perceptions
This unit deals with one of the "non-linear" dimensions of cooperative problem solving - perceptions. If we understand that each of us experiences the world differently, then we can use our different perceptions as sources of creativity and understanding, rather than as sources of dissent.
Life of a Vertebrate Fossil
This site traces the journey of fossils from discovery to display. Find out what paleontologists do in each stage a vertebrate fossil's life. Learn about digging up fossils, getting them to the laboratory, preparing them for research and exhibition, and understanding what they say about past life.
Pioneer Life With Laura
Through literature, both fiction and nonfiction, the learner will develop an understanding of and an appreciation for: Why pioneers left their homes and families to journey west; The hardships pioneers faced on the journey and as they built a new life on the frontier; Family life on the frontier; Building a community; Destruction of the way of life of the Plains Indians and their forced movement to reservations; Effects the pioneers had on the natural environment.
We'd Like to Thank You, Herbert Hoover
Since the advent of book musicals such as "Show Boat" and "Oklahoma!", many Broadway shows have touched upon relevant social and historical issues. In this lesson, students will investigate how Broadway musicals can reflect the times in which they were created. Students will examine video clips and Web sites related to relevant productions, study song lyrics, and compare and contrast actual history with Broadway history. By becoming "historical detectives," they will determine how accurately Bro
SequenceIt! is a simulation program that allows you to experience the art and logic of protein sequencing through experimentation. Your objective is to deduce the sequence of this polypeptide using many of the tools available to a practicing protein chemist. You specify the operations and the order of their application. Success in determining the protein sequence depends on your understanding of the experimental procedures and on the logic you use in executing those procedures. Operations avai
Sampling is a computer tool designed to help biology students obtain a qualitative understanding of basic concepts related to estimation and statistics. Sampling presents the user with a group of hypothetical populations distributed throughout an area, and with tools for sampling these populations to estimate characteristics such as population size and density, the nature of each population's spatial patterning, and spatial correlations in abundance between populations. By manipulating the numb
In this set of exercises, students will study rivers and waterways around them by using the Internet, maps, and their knowledge of local landscapes. The students will use an EPA Web site to investigate what is upstream and downstream of them. They will also look at graphs of flow in familiar river locations on a live U.S. Geological Survey Web site. Using small rocks and a washbasin, students will build a model that leads to extending their understanding of streams in different geographic locati
Aquifer on the Go
This demonstration should follow a class discussion on potential sources of pollution to drinking water supplies. To illustrate how water is stored in an aquifer, how ground water can become contaminated, and how this contamination ends up in a drinking water well. Ultimately, students should get a clear understanding of how careless use and disposal of harmful contaminants above the ground can potentially end up in the drinking water below the ground. This particular experiment can be done by e
