Sensitivity, initial

In co-operation with LM Glasfiber, a complete section of a rotor blade was produced with a number of well defined defects in order to perform an initial sensitivity test by means of ultrasound, vibrations techniques and real-time radiography. Based on the results of this initial test it was found that automated ultrasonic inspection was the best suited teclmique. In co-...

Irritant contact dermatitis results from first-time exposures to irritating substances such as soaps, plants, cleaning solutions, or solvents. Allergic contact dermatitis occurs after an initial sensitivity and further exposure to allergenic substances, including poison ivy, latex, and certain types of metals.

Resistance Consider transmission of rimantadine-resistant virus when treating patients whose contacts are at high risk for influenza A illness. Influenza A virus strains resistant to rimantadine can emerge during treatment and may be transmissible and cause typical influenza illness. Of patients with initially sensitive virus upon treatment with rimantadine, 10% to 30% shed rimantadine-resistant virus. Clinical response, although slower in those patients, was not significantly different from those who did not shed resistant virus. 

A brief clarification needs to be made about ESD sensitivity. As ESD is the most difficult form of insult to guard against, great attention needs to be paid to materials that exhibit high sensitivity to it. ESD initiation sensitivity was measured for only the purest form of TATP. As in all other forms of insult, the pure TATP was only slightly more sensitive than PETN. A standard deviation was done for the measurements. Using simple statistical analysis, it can be shown that TATP will initiate approximately 1 to 2% of the time with energies as low as...

Water wet HMX is added slowly to molten TNT, while continuing to stir it and to heat, until all the water is evapd. Aluminum powder is added and the mixture continued to be stirred until uniform and then cooled, with stirring, to obtain a slurry suitable for pouring into shells or bombs to serve as their bursting charges Refs 1) G.

The crysts of TNT in cast expls may vary from microscopic size to a substantial fraction of the size of the charge, depending upon casting conditions and procedure. The approach known as cream casting results in very fine crysts. In mixed expls, which usually are cast in the form of slurries, the solid particles tend to inhibit cryst growth, although TNT crysts sometimes apparently grow around the particles of the slurry. The effects of particle size on initiation sensitivity, failure diameter, and performance characteristics also have been observed to apply to crystal size in cast TNT...

Some explosive formulations based on HMX, HMX and NTO, HMX and TATB (by wt.) and binder have been studied for density, VOD, IAD (number of cards), initiation sensitivity, ignition temperature and other explosive properties. The data given in Table 2.9 and Table 2.10 show a significant decrease in sensitivity, IAD (number of cards) and initiation sensitivity of explosive formulations with an increase in the proportion of NTO as well as TATB. However, performance of the NTO-based formulation is slightly better [222].
