OPENING QUOTE

The maximum pressure at which a bursting disc will burst or open, quoted with a coincident temperature. 

In this context, I would also like to mention the six Opening Quotes provided at the front of this book. These quotes capture the essence of this book s discussions very well. At this point I invite you to read them again and to see how each one brings various aspects of our discussions to mind. 

The following procedure is the one I use and is only one of several. It will help to produce prints that are archival by a photographer s definition. In any event, you would be well served to remember the opening quote when attempting to create archival prints and negatives. 

As the opening quote indicates, the concern of pharmacologists for the safe and effective use of medicine can be traced back at least to Rudolph Bucheim (1820-1879), who has been credited with... 

The so-called hormone theory (X Ahlqvist, 1980) is based on the impact of hyperoestrogenaemia on the biliary/canalicular system and bile acid metabolism. The question of sequential causality remains open. (quot. 75)... 

In the spirit of the opening quote of this chapter, the quantum theory of atoms in molecules (QTAIM) [63] has been extensively applied to classify and understand bonding interactions in terms of a quantum mechanical observable the electron density p(r). In this chapter we will take advantage of this theory to... 

Finally, it is hoped that this presentation has sparked the interest of some readers in the quantum theory of atoms in molecules by showing how the topological properties of an experimental observable, the electron density, can be used to classify and categorise chemical bonding, in the spirit of the opening quote of this chapter. 

Theme is the most basic lifeblood of a film," says filmmaker Ric Burns (see also Chapter 17). "Theme tells you the tenor of your story. This is what this thing is about." As mentioned. Burns chose to tell the story of the ill-fated Donner Party and their attempt to take a shortcut to California in 1846 not because the cannibalism they resorted to would appeal to prurient viewers but because their story illuminated themes and vulnerabilities in the American character. These themes are foreshadowed in the film s opening quote from Alexis de Tocqueville, a French author who toured the United States in 1831. He wrote of the "feverish ardor" with which Americans pursue prosperity, the "shadowy suspicion that they may not have chosen the shortest route to get it," and the way in which they "cleave to the things of this world," even though death steps in, in the end. These words presage the fate of the Donner Party, whose ambitious pursuit of a new life in California will have tragic consequences. 

Figure 17.1 models the traditional relationship between suppliers, their customers, and end-users. The model reflects a transaction-based relationship, with the buyer-seller linkage driven by price and other conditions such as quality and delivery. But often, as the opening quote indicates, price is dominant. Ultimate end-users, on the right, have many suppliers, sometimes called vendors these suppliers, in turn, have their own... 

In the early days of chemistry over a hundred years ago, labs were not safe places. There were no fume hoods and no safety equipment, and the hazards of the chemicals were not always appreciated. The opening quote by Kekule reflects the attitude that the risks of labs simply had to be endured and... 

The opening quote of this chapter states that Man masters nature not by force but by understanding. That is why science has succeeded where magic failed because it has looked for no spell to cast. What do you think Bronowski meant by this How does this apply to chemical bonding ... 

While there are spill kits for mercury, you should seek professional assistance in cleaning up mercury spills. Unless you have been specifically trained in cleaning up hydrofluoric acid, mercury, or other reactive chemicals, you should not attempt to deal with these spills yourself. Seek additional and/or professional assistance, usually the environmental, health, and safety department of your institution or the local fire department hazmat team. These spills are especially hazardous and require more experience. Any time that you call in additional help, be prepared to tell them as much as you can about what has spilled and how much has spilled. Having an SDS handy may be helpful but most response teams will have their own resources to review (once they know what the chemical is). As the opening quote in the section reveals, a key task for a hazmat response team is to quickly identify the spill so that they know what level protection to wear and can consider the need for evacuation. 

The more we learn about the slmctures and reactivities of known materials, the better equipped we are to discover new materials and applications. Even though it may seem that most inorganic compoimds have already been discovered and analyzed, new materials, with irmnense impacts on our society, are constantly being discovered. As Buckminster Fuller states in this chapter s opening quote, we continue to find what Nature permits. In some cases, what nature permits turns out to be extremely useful to society.
