Priming ability

A general idea of the change in the minimum initiating charge of lead azide-lead styphnate mixtures with their composition is given in Fig. 58 by Grant and Tiffany [40]. The low priming ability of lead styphnate alone is also indicated. 

Gear pumps are used on sprayers with low operating pressures. They provide low to moderate volume (5 to 65 gpm) at low to moderate pressures (20 to 100 psi). Often used on special-purpose sprayers, gear pumps are positive-displacement, self-priming pumps. The self-priming ability is rapidly lost as the pump wears. These pumps are designed for oil solution formulations and wear rapidly when suspensions of wettable powders are used. The parts are generally not replaceable. The pump is not affected by solvents. 

If a check valve is used in the feed system, it should not exceed 2 psi cracking pressure, as it can interfere with the priming ability of the pump.

The determination of the initiating strength or priming ability of primary explosives is very important for the correct solution of tasks related to the service application of the primary explosives in initial devices, explosive trains, etc. 

The importance of laser light, in brief, is tliat its base characteristics, coherence, spectral and polarization purity, and high brilliance allow us to manipulate its properties. Gain switching [i, 10] and mode locking [16] are prime examples of our ability to very specifically control tire laser output. It is easy to see why lasers are tire ideal sources for optoelectronic applications. 

Poly(vinyl acetate) is used in latex water paints because of its weathering, quick-drying, recoat-ability, and self-priming properties. It is also used in hot-melt and solution adhesives. 

The combination of durability and clarity and the ability to tailor molecules relatively easily to specific applications have made acryflc esters prime candidates for numerous and diverse applications. At normal temperatures the polyacrylates are soft polymers and therefore tend to find use in applications that require flexibility or extensibility. However, the ease of copolymerizing the softer acrylates with the harder methacrylates, styrene, acrylonitrile, and vinyl acetate, allows the manufacture of products that range from soft mbbers to hard nonfilm-forming polymers. 

Galvanised steel pipes Threaded mild-steel tube is the cheapest material for water pipes, but it is not normally used owing to the amount of rust introduced into the water as a result of corrosion. Galvanised mild-steel tube overcomes this problem and may be used for nearly all hard waters, but it is not satisfactory for soft waters or those having a high free-carbon-dioxide content. The ability of a water to form a scale is, therefore, of prime importance when considering the suitability of galvanised steel for an installation. 

Organisms also evolved powerful detoxifying mechanisms that remove toxic materials or convert them to non-toxic forms or nutrients. Examples of alterations to non-toxic forms are the conversions of hydrogen sulfide to sulfate and nitrite to nitrate. The prime example of development of the ability to use a toxic substance is the evolution of aerobic metabolism, which converted a serious and widespread toxin, oxygen, into a major resource. This development, as we have seen, greatly increased the productivity of the biosphere and generated the oxygen-rich atmosphere of today s Earth. 

A prime example of the impressive nse of adhesion in nature is the gecko, which can hang from the ceiling and climb with ease np smooth vertical surfaces (Fig. 20a). Its ability to do this was known for some time to be associated with the many thousands of hairs (or setae) comprising each foot (Fig. 20b). In addition, each seta was found to con-... 

As heirs to prime New Orleans real estate, a number of free African Americans became quite wealthy before the Civil War. Norbert Rillieux s cousins included members of some of New Orleans richest families. A few of his cousins were so confident of their social status and their ability to pass as white that they signed their names without the required term free man of color, or f.m.c. Many free people of color also invested heavily in slaves. When Norbert Rillieux was in his twenties, more than 700 of New Orleans free African Americans owned an average of three slaves apiece, often family members who were eventually freed. Each of the 23 richest free people of color in New Orleans owned between 10 and 20 slaves. 

The outstanding inclusion ability and the carboxylic functions of host I raised the idea of co-erystallizing it with imidazole (Im) which, due to its versatile nature 114), is one of the frequently used components in enzyme active sites, generally presented by histidine. Formally, a system made of imidazole and an acid component may mimic two essential components of the so-called catalytic triad of the serine protease family of enzymes the acid function of Aspl02 and the imidazole nucleus of His57 115) (trypsin sequence numbering). The third (albeit essential) component of the triad corresponding to the alcohol function of Seri 95 was not considered in this attempt. This family of enzymes is of prime importance in metabolitic processes. 

Ans. It is obvious that the wording of these problems is only a little different in each case but the answers are very different. One of the prime requirements for successful completion of general chemistry is the ability to read the problems and interpret them correctly. You must not try to speed-read a chemistry text, and especially not problems on exams. 

Alcohols, just so long as they are not too bulky, e.g. MeOH, share something of water s abilities and, for example, HC1 is found to be a strong acid in methanol also. It should not, however, be forgotten that the prime requirement of the solvent is that it should be capable of functioning as a base the weaker the base, the smaller the dissociation of the acid. Thus we find that in, for example, methylbenzene (toluene) HCI occurs as such, i.e. it is almost wholly undissociated.
