Memory stick

Another simple point is that presentations should be made and given that are adapted to the audience rather than being a standard pitch. Too often the complaint is heard from one side or the other that they sat through a 30- or 40-minute dissertation of irrelevant material, or worse, hopped from one presentation to another because the information relevant to that meeting had not been collated into a coherent presentation. A practical advantage is provision of hard copies of the material as well as in electronic format - on the day - on CD, memory stick or similar device. This has increasingly become the standard of professional courtesy and if information is not provided this way it is seen as a negative point. 

The procurement agency should provide stationery to enable staff to perform the relevant tasks, including paper, letterheads, business cards and pre-printed forms as required. Computer consumables to be provided include removable storage devices (floppy disks, CDs and/or flash memory sticks), printer cartridges, printing paper, as well as any replacement parts not covered by a maintenance contract. 

For a typical reader, the PDF files themselves are likely to have been downloaded and distributed over time across a number of computers and their hard drives. From there, they may migrate to network storage areas, memory sticks and mobile devices such as iPods etc. Aggregating, removing duplicates and organizing these according to their content is non-trivial, and may well require substantial investment of human fime and skills. 

CDs, DVDs, USB memory sticks and email can be used to communicate and store information electronically ... 

This aU sounds very good, but we should remind ourselves that the route for the Stuxnet cyber-attack on the Iranian enrichment plant (its threat vector ) was most probably the simple act of leaving memory sticks in the car park. Staff working on the plant found them, put them in their pockets and later connected them to their computers. Hence the barriers listed above may sound impressive, but they can be short-circuited if vigilance is not maintained. 

Replacement of flash memory For quick writing and rewriting capabilities of the electronic devices, memristorshave a strong tendency to replace the flash memories. The memristors can be written 10,000 times or so, improving the durability of the electronic devices such as in cameras and USB memory sticks. 

Likewise, before you take a test, stick to a light snack of energy boosting and relaxing foods. A glass of milk, a piece of fruit, or some peanuts all release various memory-boosting chemicals and help you to relax and focus on the subject at hand. 

I have endeavored to keep these five example chapters as readable and enjoyable as possible. I don t discuss any esoteric concepts peculiar to biochemistry—nothing that is more difficult than the idea of stick to or cut. Nonetheless, as I mentioned in the Preface, to appreciate complexity you have to experience it. The systems I discuss are complex because they contain many components. There is, however, no examination at the end of the book. The detailed descriptions are intended only to give you an appreciation of the complexity of the system, not to test your memory. Some readers may wish to plough right through others might want to skim and refer back when they are ready for more detail. 

Throughout the book, as you would expect, there are formulae and structures of chemical compounds. You need not remember these but they are included to show the principles being covered. You are not expected to work out the names of these compounds or balance equations but after a while some might stick in your memory. 

Pitzer commented about the extremely strong inversions we measured at Shasta. You probably experienced them when you visited. They gave rise to two items of interest. One was the mercaptan release, and the other was the substantial cloud of butane that we could build up. My memory is that we were still using the line source. In any event Bill and Tom started worrying about the possibility of igniting the cloud with a spark from the mercury cup anemometer. It was decided that the risk was low, but I think we all still worried. Bill s son asked me if it was true that we blew up five gallons of mercaptan with a stick of dynamite. 

An additional problem is that known elements in the periodic table, e.g. boron (B), tungsten (W) and molybdenum (Mo) tend to stick in the transport fine, nebuliser, spray chamber and torch causing memory effects in atomic spectroscopy. Elements that stick cause problems with quantification, and detection Emits and it is important that methods of reducing these are rigorously applied in analysis of these elements. However, memory effects in ICP-OES are not as pronounced as they are with graphite furnaces for refractory elements but they are present to some extent, and must be reduced or removed. 

Non-polar, high-molecular-weight compounds or matrix components are often annoying. They will stick onto rough, dirty surfaces. This tells you indirectly what to do. To avoid memory effects, improve your sample preparation and make sure your equipment is clean.
