U.S. says Gaddafi weakened but not defeated
U.S. military officials say Gaddafi is not close to a military breaking point even though coalition strikes have seriously degraded his fighting power. Deborah Lutterbeck reports.
Eureka! Episode 10 - Potential Energy vs Kinetic Energy
A rock teetering on the edge of a cliff is shown to have potential energy - the energy of position. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level. (04:51)
Kinetic Energy and Work
Animated billiard balls help demonstrate kinetic energy - the energy of motion. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Other key vocabulary words addresses in this video include: work, force, mass, acceleration, newtons, joules, innertia, gravity, movement, speed, distance, and transfer of energy. (04:49)
Compiler Confidential | GoingNative 2013 Modern CPU and instruction set architecture improvements are critical to the performance of software, but it's the compiler that can make your code sing. Come learn how compiler optimizations are enabling the next generation of native code performance. This talk will go deep into the guts of the Visual C++ compiler optimizer, focusing on compiler optimizations from the point of a view of modern CPUs. Down to the metal we go!

5.1 Pollution and loss of biodiversity
To be able to understand the importance of the environment for our health, we need to know a little about the interdependence between environment and humankind. This unit will look at interactions between plants, animals and the physical and chemical environment, as well as considering ways in which humans have altered, and are altering this environment. These changes have health implications that are not always immediately obvious. Frequently, we initiate changes that are going to have their ef

C21: Physics Teaching for the 21st Century
Physics Teaching for the 21st Century is a resource for teachers who are interested in teaching physics concepts in real world contexts. The great problems of the 20th century were solved by a few incredibly smart people. The great problems of the 21st century will have to be solved by billions of moderately smart people. This is where teachers come in... In this website you will find: * articles that clearly explain the physics concepts in a real world context * take-home experiments that ca
This site is a wonderful resource for undergraduate researchers and their mentors. Topics covered include research nuts and bolts, funding your science, scientific ethics, lab safety, communicating your science and mentoring issues. The site makes good use of case studies, self-study questions and references on each topic.
Molecular Expressions Microscopy Primer: Physics of Light and Color - Lenses and Geometrical Optics
This webpage contains a series of java applets which illustrate the physics of image formation and the effect of aberrations on image distortion. As this webpage is part of a larger website on microscopy and imaging, there is a manu on the left-hand side of the webpage that guide the user to primers on microscope operation, confocal microscopy, digital imaging, and photomicrography.
RSC.org: Mass Spectrometry
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There\'s also an excellent example of the use of high resolution MS to differentiate between nominal mass and actual mass. The video does a very good job of explain
This webpage, part of a larger project \"Understanding Chemistry\", provides a solid introduction to UV-vis spectroscopy suitable for use in introductory chemistry and introductory analytical chemistry courses. The UV-vis pages discuss UV-vis light, absorption, Beer\'s law, the double-beam spectrometer, and introduce some standard applications of UV-vis spectroscopy. Explication is clear and thoughtful. Judicious and effective use of graphics. Site is easy to navigate, and the links work.
Flame Atomic Absorption
In addition to being an introductory tutorial on Atomic Absorption Spectroscopy, the parent site has links to a variety of materials on environmental analysis including immunoassay, ICP, ISEs, mass spectrometry, ground water monitoring, soil sampling and so on. The index link for the parent site seems to be broken, but the other topics can be accessed using the next topic button on the bottom of each page.
Compilation of FTIR Materials
Provides excellent tutorials on the principles of IR absorption, interpretation of spectra for structure determination, a spectral peak wizard, an authoritative glossary of spectroscopic terms, and links tutorials on how FT instruments work.

LRMA: Barbara Sorenson Topographies
The Leepa-Rattner Museum of Art opened January 22, 2002 on the Tarpon Springs Campus of St. Petersburg College. The Museum's 20th century collection is made up of art from Abraham Rattner's estate donated by Allen and Isabelle Leepa and a large donation made by the Tampa Museum of Art in 1997. The Museum is filled with Rattner's retrospective works: lithographs, tapestries, sculptures, paintings and stained glass. It is sure to be the largest assemblage of Rattner's work in the world as efforts
Co-operation and contestation: farmer-state relations in agricultural transformation, An Giang Provi
This thesis analyses farmer-state, and farmer-farmer relations in the Mekong Delta, Vietnam, focusing on agricultural transformations in An Giang Province. It does so at three levels: first, at the largest scale, farmer-state relations are explored through the building of common dikes of different heights; second, farmer-farmer relations are examined through farmers’ management of flood water within common August dikes; and third, at the smallest scale, the scope for interhousehold diversific
5.1 Difficulties in interpretation
Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information. This unit will help you to develop the skills you need to do this. This unit can be used in conjunction with the ‘More working with charts, graphs and tables’ unit, which looks into more ways to present statistical information and shows y
