The AND operation combines two binary words bit by bit according to the rules

• 0 AND 0 = 0

• 0 AND 1 = 0

• 1 AND 0 = 0

• 1 AND 1 = 1

In other words, only when both bits are 1 is the result 1. You may find it helpful to think of it this way: when one bit is one and the other bit is 1 the result is 1.

If we add 109.8 ml of one liquid to 6.5 ml of another liquid, what would be the total volume of liquid in ml?

To compare 109.8 with 6.5, you need to remember that

Place the two numbers in a grid on top of each

After studying this course, you should be able to:

• discuss how the gas mixture expelled from the engine, and the conversion performance of the three-way catalytic converter, depend on the air/fuel (A/F) ratio

• list the chemical reactions whereby the three-way catalyst removes carbon monoxide (CO), hydrocarbons and oxides of nitrogen (NOx) from petrol vehicle exhausts

• interpret the results of experimental studies (involving activity

An important dimension to the social perception of risk is how the media report an issue. Researchers at the Cardiff University School of Journalism investigated media coverage of three scientific issues with social policy implications: climate change; cloning and genetic medical research; and the MMR vaccine. The study analysed the way the media covered the MMR controversy in 561 articles over a seven-month period. Then two nationally representative surveys were carried out in April and Octo

Jim Madigan • Robbie Vrolyk postgame vs. Massachusetts (Feb. 3, 2012)
In its seventh overtime game of the season, junior Vinny Saponari sent the Northeastern men's hockey team to its first triumph in extra time as the Huskies bested Massachusetts 22 seconds into overtime for the 4-3 victory on Friday night at Matthews Arena. Third-year forward Robbie Vrolyk supported Northeastern's efforts thanks to a two-goal performance while rookie Adam Reid netted the other tally in regulation. Vrolyk has notched three goals in his last two games as his last two-goal outing c

• We are biologically predisposed to provide for our offspring and may try to ensure that this provision continues after our death. However, our interactions with other members of society are wide-ranging and many people leave legacies to benefit the wider community.

• All species alter their environment to some extent because they do not live in isolation from one another. The study of the interactions between plants, animals and their environ

Southern Secession
This video is accompanied by text. "When Americans voted Lincoln president, James Buchanan officially became a lame-duck leader. Southerners worried that Lincoln’s victory, which received no support from the South, would lead to political and economic dominance by the North. Slavery, they feared, would be restricted and possibly outlawed. Southerners believed that by claiming their independence they could develop their own banking system and establish trade directly with Europe. No longer woul

Water must be of a certain quality to be suitable for human consumption. No natural water found on Earth is pure; any sample of water contains more than just water molecules. Some materials, such as sodium nitrate, are very soluble and dissolve in water in large quantities, whereas other materials are much less soluble. This is just as well, otherwise rain would dissolve all the rocks and they would end up in the oceans!

Drinking water must not contain harmful materials, which means bot

Health, disease and society: Scottish influence in the 19th century
This free course, Health, disease and society: Scottish influence in the 19th century, examines the role that Scots played in contributing to the developments in healthcare during the nineteenth century. The radical transformation of medicine in Europe included the admission of women as doctors and the increased numbers of specialised institutions such as asylums. Such developments were also influenced by wider social, economic, political and cultural backgrounds these are also examined.

Middle School Portal: Math and Science Pathways (MSP2)
This resource discusses how scientists and engineers study biological systems to develop artificial systems, in this case artificial olfaction. The sense of smell is extremely complex, and scientists working on artificial olfaction have had to study this biological system extensively to extract some basic principles upon which to build their devices. Disciplines of emphasis will involve biology, chemistry, electronics, and teamwork. Copyright 2005 International Technology Education Association

7.340 Learning and Memory: Activity-Controlled Gene Expression in the Nervous System (MIT)
The mammalian brain easily outperforms any computer. It adapts and changes constantly. Most importantly, the brain enables us to continuously learn and remember. What are the molecular mechanisms that lead to learning and memory? What are the cellular roles that activity-regulated gene products play to implement changes in the brain?How do nerve cells, their connections (synapses), and brain circuits change over time to store information? We will discuss the molecular mechanisms of neuronal plas
