Polaris

The use of more complex or more costly articles of equipment, such as catalytic hydrogenation apparatus, autoclaves, polari-meters, ultraviolet absorption spectrometers, etc., has not been described, because the type of such apparatus employed indifferent laboratories varies considerably, and students must be taught the use of their own laboratory equipment.

Method 1613 of US Environmental Protection Agency (US EPA) was used for the PCDD detection in the objects of environment (water, soil etc.). PCDD detection was done with the help of Polaris Q gas chromatograph/ mass spectrometer on mass-spectrum of electronic impact in the MS-MS mode. Division of isomer PCDD was carried out on a capillary column from the sintered quartz DB-5 MS (60 m x 0,25 mm, thickness of tape 0,25 p.m). The same device was used for detection of fungicides formulations active ingredients in soil. 

In conclusion I desire to thank Dr. J. McCrae, who has written the section on Ethyl Tartrate and the use of the Polari-meter. Dr. T. S. Patterson, who has been kind enough to look over the proofs, and Mr. H. D. Dakin, who has given me substantial assistance in the practical work of revision.

At this time the major uses of double-base smokeless compns are in Navy rocket weaponry and gun proplnts. The 2.75-inch FFAR, Sidewinder, SHRIKE, ASROC and Polaris weapon systems employ such proplnts. The major dis-... 

Without the influence of burning rate catalysts most of these hydrocarbon prop bits have similar burning rates and ballistic behavior. They may differ significantly in mechanical properties, particularly as a function of temp. Most hydrocarbon-based composites are used in larger rockets because of their ease of fabrication and high specific impulse. Polaris first and second stages, the Titan 3C booster rocket and Mlnuteman are all powered with composite proplnts... 

Exchange reactions can be sometimes investigated by the techniques of polari-metry, nuclear magnetic resonance and electron spin resonance. The optical activity method requires polarimetric measurements on the rate of racemization in mixtures of d-X (or /-X) and /-Y (or d-Y). 

The PERT technique was developed in connection with the Navy s crash project to produce the Polaris submarine. It is given much of the credit for the completion of that program 18 months ahead of schedule. In another spectacular success, the turnaround time (the time necessary to shut down, repair, maintain, inspect, and start up the unit) for a methanol unit was cut from 12 to 9 days, with no increase in personnel, by using CPM. This is especially impressive since a similar turnaround had been done annually for 25 years,2 and using the best methods available the turnaround time had never been less than 12 days. 

It has already been noted that PERT was developed to speed up the Polaris project. The Navy was dealing with hundreds of subcontractors, each constructing parts in a different location. These were then sent to an assembly point where the submarine was put together. Until the items arrived there, the activities were essentially independent. This is different from CPM, which was developed mainly for maintenance turnarounds at a given location. Under these conditions, everything was closely interrelated.

For comparison purposes, two other MS systems have been used with in vitro grown parasite cultures. In the first case, a home-built miniaturized linear TOF multi-array analyzer1718 was interfaced to the frequency-tripled output at 355nm of a Q-switched Nd-YAG laser ( Polaris, New Wave Research, Fremont, CA). In this experiment the laser beam was not scanned, and the estimated laser fluence after attenuation was similar to that of the commer-... 

The mass spectrum of palmitic acid obtained by DE-MS with a Polaris Q ion trap external ionisation mass spectrometer is presented in Figure 4.2 (Ribechini et al., 2008a). Dominated by a base peak at mJz 87, it presents a visible molecular peak at mJz 256, accompanied by a fragment at m/z 257, possibly formed by rearrangement in the ion trap. The loss of the...
