Aston Martin DB9 – A Striking Balance.pdf
Taken from 100% Aston Martin Engineered to be the World’s Finest Sports GT: DB9 is new from the ground up. Every feature has been tailored to make the world’s finest sports GT.
The starting point was to define the ideal dimensions, proportions and materials for the chassis. Aston Martin did not use an adapted platform from an existing family or luxury saloon – the most common starting point for GT cars. This approach can lead to compromise in styling and weight and loss of character.
Automating Manufacturing Systems with PLCs.pdf
Taken from PROGRAMMABLE LOGIC CONTROLLERS’s Introduction: Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution, the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s, and has become the most common choice for manufacturing controls.
PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer: Cost effective for controlling complex systems.
Flexible and can be reapplied to control other systems quickly and easily.
Computational abilities allow more sophisticated control.
Trouble shooting aids make programming easier and reduce downtime.
Reliable components make these likely to operate for years before failure.
Who Cares: Sources of Information About Health Care Products and Services.pdf
Taken from Introduction: With so many sources of health information at your fingertips — many of them online - it can be tough to tell fact from fiction, or useful health products and services from those that don’t work or aren’t safe.
Influenza Report 2006.pdf
Taken from Preface: Thirty years ago, infectious diseases were seemingly on the decline.
Tuberculosis was defeated, small pox was about to be eradicated, sexually transmissible diseases could easily be treated, and other scourges of mankind, such as malaria, were expected to disappear one day. Some experts hilariously announced that we would soon be able to close the book of infectious diseases once and for all. Of course, that was before the beginning of the AIDS pandemic in 1981, and before the discovery of the hepatitis C virus, as well as many other viruses capable of causing severe disease in humans.
Human memory is permeable and porous. A quick look at medical history would have sufficed to understand that infectious diseases have accompanied humans ever since they opted for a sedentary lifestyle. While we are today better prepared to prevent and fight off infectious diseases, we are nonetheless condemned to coexist with them. In a world with an increasing potential for the rapid spread of pathogens – overcrowded cities, high mobility – the role of efficient infectious disease task forces can therefore not be overestimated.
