A partial solution to this dilemma could be that a large proportion of the protein-rich foods (meat, eggs) consumed by these people came from animals that were themselves fed a C4 diet. We know that dogs typically share the same diet as humans (Katzenberg 1989 Cannon et al. 1999) and are important components of the diet in some sites (eg., Cuello Hammond 1991 van der Merwe et al, this volume). It is unlikely that all the meat consumed by Maya peoples was derived from pure C4 consumers, however, as we have evidence for at least some C3-based animal bones that are presumed to be waste from food preparation. This should a subject of future study to test for the degree of domestication (and consequent feeding on maize) of meat-supplying animals such as turkeys. 

The question of the stability of the biomolecules is a vital one. Could they really have survived the tremendous energies which would have been set free (in the form of shock waves and/or heat) on the impact of a meteorite Blank et al. (2000) developed a special technique to try and answer this question. They used an 80-mm cannon to produce the shock waves the shocked solution contained the two amino acids lysine and norvaline, which had been found in the Murchison meteorite. Small amounts of the amino acids survived the bombardment , lysine seeming to be a little more robust. In other experiments, the amino acids aminobutyric acid, proline and phenylalanine were subjected to shock waves the first of the three was most stable, the last the most reactive. The products included amino acid dimers as well as cyclic diketopiperazine. The kinetic behaviour of the amino acids differs pressure seems to have a greater effect on the reaction pathway than temperature. As had been recognized earlier, the effect of pressure would have slowed down certain decomposition reactions, such as pyrolysis and decarboxylation (Blank et al., 2001). 

In some countries (e.g. in the U.S.S.R. and in the U.S.A.) thick strips (for cannon powders) may be cut immediately after the extrusion of the tubes. This is possible only when pyrocollodion cotton is used for the manufacture of the powder since it is easily soluble and requires only a small amount of solvent (about 80% by weight of nitrocellulose). After cutting the powder is subjected to predrying. When... 

After drying, cannon powders, i.e. strips or tubes, are subjected to a second grading as they may have been distorted or discoloured on soaking. 

As the invention of gunpowder has been popularly ascribed to Bacon and to Schwartz, so the use of ordnance baa been referred to the time of tho battle of Creasy—134G. - To puss over the Chinese hypothesis, on this part of the subject, it will bo found that cmraon were known at least as early as the year 1312. This is derived from the acuree quoted by Casiri from Arabian writers wbo in 1312 and 1323 describe the uea of ordnance whilst,If Barbour Is to be trusted, Edward ITT. was also provided with some pieces of artillery in 1327, and P%re Daniel assorts that cannon were known to the French in 1338. This discussion need not bo carried lower though, in favor... 

Exercise. A cannon projects a ball with initial velocity v at angle 9 with the horizontal. Both v and 9 are subject to uncertainties that can be described by a Gaussian distribution for each. The distributions are centered at v0 and 60, respectively, and so sharp that non-physical values, such as negative v or 9, may be ignored. What is the probability distribution of the distance covered by the cannon ball ... 

The wheellock was developed about 1515.31 This was an important development in firearms as, apart from dispensing with the need for a glowing match, the wheellock mechanism could be produced in any desired size which made possible the production of pistols small enough to be carried about the person. As with the hand cannon, combined wheellock weapons were produced where pistols were attached to weapons such as maces, swords, and crossbows. The wheellock mechanism was intricate and subject to mechanical failures which were difficult to repair. This prompted a search for a simpler, more reliable mechanism, resulting in the introduction of the flintlock.

Gunnery is the art or practice of using cannons or machine guns either on the ground or in the air (Ref 6). It comprises the following three subjects a) exterior ballistics b) interior... 

During the past thirty years a tremendous volume of literature has dealt with all aspects of solid proplnts. A comprehensive review of all this literature is quite beyond the scope of this Encyclopedia. Indeed an all-inclusive discussion of SP would require an entire Encyclopedia wholly devoted to solid proplnts. The im-practicality of a comprehensive review is not the only reason for limiting the scope of the present article. Solid proplnt literature suffers more than usually from repetition and poor quality. Thus even in a comprehensive review, considerable selectivity of subject matte is imperative. Furthermore, as shown below, certain aspects of SP, in particular cannon propints, have already been treated iri previous Encyclopedia volumes... 

Before Capt- Rodman cast his 450-pounder cannon, illustrated on page 305 of our last volume, he made a series of experiments to determine not only the best kind of iron to be used in the casting, but also the proper form for the mammoth ordnance. The extent and variety of knowledge made available in determining the form of ibis simple mass of cast-iron, maybe judged by the following list of only a small part of the subjects Bscussed in Capt. Rodman s report ... 

Carl Bosch took on the task of scaling up the converter. Stainless steel, that would have avoided many problems, was not available. What was available was the type of steel that withstood the great heat and pressures of massive cannons, though cannons were not subjected to hydrogen under such conditions. Explosions of the test converters were frequent, caused by embrittlement as carbon in the iron of the converter combined with...
