What is ‘e-commerce’? This unit will look at typical application areas including the internet, supply chain management and online auctions. It will also help you to understand the underlying technologies used to implement e-commerce applications before looking at some of the problems that can be encountered when developing distributed e-commerce systems.
Objectives for Section 5
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
5.4 Expressions
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
5.3 Comparison functions
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
5.2 Operations on Boolean values
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
5.1 Arithmetic operations
This unit will help you to understand the forms of data that are handled by software and look at the various processes that can be applied to the data. These ideas are demonstrated through the use of a supermarket till and illustrate how simple data sets can be manipulated.
Too Big or Too Small?
This lesson features three activities to promote number sense with large numbers, fractions, and decimal operations. In the first activity, students use proportional reasoning to determine whether $1 million in $1 bills would fit in a suitcase and how much it would weigh. In the second activity, students use circular regions to develop their sense of the relative sizes of fractions between 0 and 1. In the third activity, students play a game that develops their sense of the effect that operation

The Mexican American War
Conflict between U.S and Mexico started when Mexico insisted that its northern border lay along Nueces River, while U.S.claimed that it was farther south along Rio Grande. President Polk sent Zachary Taylor to the troubled area, but the two sides clashed and U.S. soldiers were killed, leading to Congress' declaration of war. The Mexican War gave U.S. more land, but led to more conflicts between free/slave states. This four minute video explains this and is accompanied by text to make it easier t
Learn about The Civil War 1861 - 1865
This 4:50 minute video is about events leading up to the Civil War and the major events duing it. President Lincoln's election led many southern states to secede and the war initially began in Fort Sumter. The first battle of Bull Run (1861) showed both sides how unprepared they were. The Emancipation Proclamation was issued in 1862. In 1863, the Mississippi River was under union control. In the same year, the Gettysburg Battle and Vicksburg both turned victory to the union army. In 1864, Confed
Christians and the Holocaust: Get involved today
Yad Vashem is so much more than a Holocaust Memorial. It is an educational institute that seeks to educate about the Holocaust and anti-Semitism and related themes. Holocaust was the murder of 6 million Jews by Nazis and their collaborators. Many factors contributed to the mass murder including centuries of Christian anti-Semitism in Europe. Today Yad Vashem reaches out to Christians worldwide through educational programs and invites them to join the Christian Friends of Yad Vashem.

OMG! There's Discrimination in the Modeling Industry! Nuclear Physics Group Philips: What if You Could Carry Your TV Around? Semiactive Damping of Cables with Sag
<img src="http://mises.org/Controls/Media/DocumentImage.ashx?Id=6368" vspace="4" hspace="4" style="margin: 10px;" /><br />
This website features the Nuclear Physics Group at the University of Birmingham's research related to understanding nuclei properties by studying the behavior of their constituents. Visitors can learn about the investigations undertaken by the five subgroups: Relativistic Heavy Ion Collisions, Exotic beams studies, Laser Spectroscopy of Unstable Isotopes, Positron Emission Tomography, and Nuclear Power Energy. Students and educators can discover how under high temperature and density a quark is
Philips Research demonstrated "the world's first matrix display that keeps functioning while being bent," and it has great expectations for the technology. Although it will probably not be commercially available for some time, it is intriguing to envision being able to unroll an e-book to read. A broad introduction to flexible displays is given on this Web site. Several potential technologies that could be used to manufacture the devices are discussed, including organic light-emitting diodes and
Vibrations in support cables can be caused by wind, rain, or other forces acting on the attached structure. This can result in premature failure of the cable or its connections, thereby reducing the cable's useful lifetime. This research paper, from the University of Southern California civil engineering department, extends the previous work of the authors on smart vibration damping techniques. Through accurate modeling of the cable and including the properties of "sag, inclination, and axial fl
