Gold command

Regular repeated reassessment of the scene is a key responsibility of commanders at both silver and bronze levels. Information must pass from bronze to silver to gold command and back down the same channel. 

The emergency services responses at the scene are controlled by the individual service commanders, who together comprise the joint emergency services control centre or silver command. The silver commanders report to their gold command. Ambulance, police and fire commanders will usually be appointed. A medical incident commander will be appointed in incidents involving significant numbers of live casualties. 

The UK Armed Forces can be tasked to provide assistance at major incidents (including terrorist incidents) under the Military Aid to the Civil Powers (MAC) regulations. A request for mUitary assistance is the responsibility of the gold command and, once assistance has been agreed, a military-civilian liaison officer will be appointed (usually a senior local commander). 

Expectant patients are those whose injuries are so severe that attempting to save them would divert precious resources from other casualties with a greater chance of survival, with no significant chance of a successful outcome. The decision to invoke the expectant category must be taken at silver level and preferably only after discussion with gold command. 

The Health Protection Agency is responsible for health advice on radiation exposure as well as chemical and biological, both locally and at a national level with representation at COBRA and Gold Command.

The potato originated in South America1 where the Incas cultivated and consumed it about 13 000 years ago,2 therefore the history of the potato in Europe and elsewhere in the world began after the discovery of the Americas. When the Spaniards, commanded by Pizarro, conquered Peru and Chile (1525-1543) they found both huge amounts of gold and the potato. They brought this new kind of food to Europe. From 1570 onwards, the potato spread throughout Europe.3... 

With the coming of the millennium, Advances in Physical Organic Chemistry will have a new Editor. After being associated with the editorial side of the series since 1975, first as Associate Editor, then as Co-Editor and finally, after the sad, premature death of Victor Gold in 1985, as Editor, it seemed to me that it was an appropriate time to pass on the baton to a younger pair of hands. Academic Press have been fortunate to secure the services of Professor Thomas Tidwell of the University of Toronto to lead the series into the next century. I leave the series confident that he will command the support of the whole physical organic chemical community and further extend its appeal. My thanks go to the members of my Editorial Advisory Board, the ever-changing editorial staff at Academic Press, the many contributors who. 

In Nigeria wealth was displayed in quantities of ivory jewellery in the form of simple bracelets and anklets, and ornaments for the home. In other African countries ivory was used for much less ostentatious items, such as hairpins or ear studs. With the arrival of the Europeans a market opened up for exporting carved objects, but most of the material was exported in its raw state. In the time of slavery it became part of the white gold/black gold story. Local men were commandeered to carry the tusks to the coast and onto the ships, after which the men themselves were ordered to stay on board and were taken away to be traded as slaves. 

In another example, a mixed monolayer composed of a photoisomerizable component and an electrochemical catalyst was applied to switch the electrocatalytic properties of a modified electrode between ON - and OFF -states. A gold electrode surface functionalized with a spiropyran-monolayer and pyrroloquinoline quinone (PQQ) moieties incorporated into the mono-layer was applied to control the electrocatalytic oxidation of NADH by light [92]. The positively charged merocyanine-state interface resulted in the repulsion of Ca2+ cations (promoters for the NADH oxidation by the PQQ), thus resulting in the inhibition of the electrocatalytic process. In the nitrospiropyran-state the monolayer does not prevent association of the PQQ-catalyst and Ca2+-promoter, so provides efficient electrocatalytic oxidation of NADH. Similar results have been achieved by a combination of the photo- and thermal effects resulting in the isomerization of the spiropyran-monolayer with the incorporated PQQ-catalyst [93], Other photoisomerizable materials such as an azobenzenealkanethiol derivative mixed with a ferrocene-redox component have also been used to control the electrocatalyzed electron transfer process between a command interface and a dissolved redox probe [94].
