Social work learning practice
This audio unit focuses on the importance of people's backgrounds and experiences in the field of social work. It identifies the diverse ways in which service users and social workers define themselves, helping you to understand how the two groups perceiv
The EJS Helmholtz Coils Model shows a the magnetic field between two circular coils of wire. The default configuration, known as a Helmholtz coil, sets the separation distance D equal to the coil radius R. These values produce a nearly uniform magnetic field B between the coils.
Unit 4 - Taking action for household food security (Module 3)
In this unit you will get the opportunity to apply your knowledge and skills when you work in groups using certain tools and methods, which are common in the field of food security.
Mary Wollstonecraft and Mary Shelley
This Honors Program first-year political theory seminar explores the intellectual relationship of Mary Shelley, the author of the novel Frankenstein, to her mother, Mary Wollstonecraft, the author of the first book on women's rights, A Vindication of the Rights of Woman.
Choosing a Career in Health
There are two lessons in this group. The first lesson is a lab activity that illustrates the importance of hand washing as a way to prevent the spread disease. The second lesson includes discussion of various careers in the health field and allows students to explore careers utilizing various resources.
FUSE-MOLA: Mars Once Had Oceans
This visualization shows how Mars might look with an ocean at -500m where the lowest point on Mars is about -8000m and the highest point is about 22000m. Data from The FUSE spacecraft and from the Mars Global Surveyor-MOLA instrument where used to support this theory.
Topological Features of a Compressible Plasma Vortex Sheet: 6 Cases
The Voyager and Pioneer Spacecraft have detected large-scale quasi-periodic plasma fluctuations in the outer heliosphere beyond 20 AU. A plasma vortex sheet model can explain these fluctuations and the observed correlations between various physical variables. The large scale outer heliosphere is modeled by solving the 3-D compressible magneto-hydrodynamic equations involving three interacting shear layers. Computations were done on a Cray computer at the NASA Center for Computational Sciences. S
Bastille Day Flare Animation
Fly-in of TRACE full sun image to the flare location. Fade to a model of the field lines with a magnetogram of the solar surface. Pull back out to display a movie of flare images. This version uses lens flares to illustrate matter motion along the field lines.
Bastille Day Flare without Matter Motion
Fly-in of TRACE full sun image to the flare location. Fade to a model of the field lines with a magnetogram of the solar surface. Pull back out to display a movie of flare images. This version does not show the matter motion along the field lines.
Closeup of Solar Tadpoles with time tags
Here is a close-up view of dark tentacles or tadpoles moving towards the solar surface in this solar flare of April 21, 2002 seen by TRACE. One theory proposed in this press release is that they are due to voids created by magnetic reconnection in the flare. This version of the visualization displays ...

When a large bundle of magnetic field lines breaks through the Suns surface, a sunspot can form. Sometimes, a smaller spot will emerge nearby, creating a magnetically complex region where particles are energized and then violently expelled. Supercomputer models show that rearranging magnetic field lines ...
Mapping Magnetic Influence
This lesson allows students to explore magnets and the region of influence around a magnet called a magnetic field. They will learn that magnets exert a force on a magnetically sensitive object without coming into direct contact. Students will create a map of the magnetic influence around the magnet.
Magnetic Globe Lithograph
This activity demonstrates what a dipole magnetic field looks like in 3D. It was developed because the commonly used classroom demo (iron filings on a sheet of paper on top of a bar magnet) leads to student misconception that magnetic fields are two-dimensional. The reverse side of the litho features ...
Scaling of CMOS devices into the nanometer regime leads to increased processing cost. In this regard, the field of Computational Electronics is becoming more and more important because device simulation offers unique possibility to test hypothetical devices which have not been fabricated yet and it ...
Nanoscale Antenna Apertures
This presentation will discuss light concentration and enhancement in nanometer-scale ridge aperture antennas. Resent research, including numerical simulations and near field optical measurements has demonstrated that nanoscale ridge antenna apertures can concentrate light into nanometer domain. More ...
Nanoelectronics and the Meaning of Resistance
The purpose of this series of lectures is to introduce the "bottom-up" approach to nanoelectronics using concrete examples. No prior knowledge of quantum mechanics or statistical mechanics is assumed; however, familiarity with matrix algebra will be helpful for some topics.
Quantum Dots are man-made artificial atoms that confine electrons to a small space. As such they have atomic-like behavior and enable the study of quantum mechanical effects on a length scale that is around 100 times larger than the pure atomic scale. Quantum dots offer application opportunities in ...
Why is Nanotechnology Multidisciplinary? A perspective of one EE
The field of nano-science and nano-technology covers a broad area of expertise. Classical fields of Physics, Chemistry, Material Science, Electrical/Mechanical/Chemical Engineering all are involved in the "new" field f nano. Research and development in that area is by its very nature multi-disciplinary, ...
Introduction to Nanometer Scale Science and Technology
This seminar will provide an introductory overview for non-experts of the emerging field of nanometer scale science and technology. The following topics will be emphasized: (1) Historical background and motivation for the study of nanometer scale phenomena; (2) Strategies for controlling the structure ...
