The NHTSA does review trends in fatalities and rates and makes forecasts. The Fatality Prediction Model used is based on a technological approach and is essentially a vehicle mix-crashworthiness model. Factors and their effect on the number of fatalities predicted for 1990 compared to 1980 are of fatalities relative to 1980 are vehicle downsizing (-t-10,000), increase in number of licensed drivers ( + 5,000), smaller percentage of young drivers (-3,000), increase in vehicle miles of travel per licensed driver (+4,000), increase in

The FHWA acknowledges the interrelated system of vehicle, hiunan and roadway environment in their general discussion of traffic safety. See U. S. Department of Transportation. National Highway Traffic Safety Administration and Federal Highway Administration. Midway Safety 84. A Report on Activities Under the Highway Safety Act of 1966.1986, page 68. The fact that two administrations vduch deal with traffic safety are located in the same Department and use incompatible approaches is an example of nonmarket failure.

Sodium Fusion on Semi mlcro Scale. The Lassaigne test can be readily carried out with as little as 0 01 g. of material, using sodium pellets about 2 mm. in diameter in a tube about 3 x. After fusion, the red-hot tube is plunged into distilled water in a small porcelain crucible or in a boiling tube. The mixture is then heated, filtered and tested as already described. 

Rather than continuing to deal with abstractions, let us plunge right in by carrying out a bare bones MM calculation. After the reader has a practical sense of how MM calculations work, we shall return to some of the topics referred to above in more detail and we shall introduce some others. 

Prepare a coil of copper wire by winding several turns around a glass tube. Heat the coil in the oxidising flame of a Bunsen burner for 1-2 minutes and plunge the spiral, whilst still red hot, into a test-tube containing a solution of 1 ml. of methyl alcohol and 5 ml. of water. Stopper the test-tube loosely, cool, remove the wire, and repeat the process two or three times. Observe the odour of the solution and use it (or formalin diluted with water) to carry out the following tests. 

Prepare the acetaldehyde solution by plunging a red hot oxidised copper coil (made by winding a copper wire round a glass tube and heating the resulting coil in a Bunsen dame) into 6 ml. of 60 per cent, alcohol in a Pyrex test-tube. Withdraw the coil, cool the test-tube under the tap, repeat the oxidation several times, and use the cooled solution for the test. 

In a plastic container the chemist dissolves her golden yellow freebase oil into some DCM, ether or ethanol. The chemist then starts a steady dripping of the sulfuric acid into the HCl/salt and white, puffy HCI gas will start to exit the glass rod or pipette which is at the end of the hose. That tip is then plunged into the sol-vent/freebase solution to bubble the gas through the solvent. 

The bitumen in the Athabasca deposit, which has a gravity on the API scale of 8°, is heavier than water and very viscous. Tar sand is a dense, soHd material, but it can be readily dug in the summer months during the winter months when the temperatures plunge to —45° C, tar sand assumes the consistency of concrete. To maintain acceptable digging rates in winter, mining must proceed faster than the rate of frost penetration if not, supplemental measures such as blasting are required. 

Lead alloys containing small amounts of calcium aie formed by plunging a basket containing a 77 or 75% calcium—23—25% A1 alloy into a molten lead bath or by stirring the Ca—A1 alloy into a vortex created by a mixing impeUor (19). 

It is necessary to modify the edge of the hole in various ways to reduce these stress concentrations. Some methods of modification are priming, plunging, and standard radiusing and polishing methods. In the Dry Low NOx Combustors, especially in the lean pre-mix chambers, pressure fluctuations can set up very high vibrations, which lead to major failures. 

On the completion of nitration the batch is dropped from the reaction vessel into a centrifuge and the acid mixture spun off and recovered. The nitrated linters, which still contain appreciable quantities of acid, are then plunged into a drowning tank, where the nitric acid is diluted with a large volume of water. The resultant ester is then pumped, as a slurry, into storage vats which may hold the products of several nitrations. 

The extrudate is cut up into appropriate lengths and cooled by plunging into cold water. Subsequent operations depend on the end-product required.
