Cefsulodin (60) has a sulfonic acid nx)iety on the C-7 acyl side chain. This moiety conveys antipseudomonal activity to certain penicillins, and it is interesting to note that this artifice works with cefsulodin as well. It is also interesting that, in contrast to the other so-called third-generation cephalosporins, the spectrum of cefsulodin is rather narrow and its clinical success will place a premium upon accurate diagnosis. Its synthesis begins by acylation of...

Petard d alarme (Fr). A device classed as an artifice de signalisatlon sonore and used on railroads for signalling purposes. It consisted of a waterproof container with a mixt of 2p Sb sulfide and Ip K chlorate, to which was added a small quantity of powdered glass. After inserting a primer, the ensemble was attached to the upper surface of a rail. When the wheel of a locomotive contacted the primer the charge expld, producing a loud report Ref Pepin Lehalleur (1935), 477... 

Petards (ou artifices 1 pour signaux (Fr). Used during WWI to attract the attention of neighboring troop units or fortifications. The devices consisted of boxes filled with about 400kgs of BlkPdr. They produced a report which could be heard for a distance of 3km, and the smoke produced gave the location of the signalling unit Ref Pepin Lehalleur (1935), 477... 

The problem of crystallizing glycerol proved to be of some interest. A tube of glycerol ua.r kept with one end in liquid air. the other at room temperature for a period of several weeks without results. Seeding with various organic crystals of similar structure tt s also tried. In fact, the artifices ordinarily used for starting crystallization in the absence of seed crystals were all tried without success. 

The foregoing derivation may appear artificial in view of the assumptions involved. The contribution of a given bond to x is by no means restricted to the two unique values, + as has been assumed. On the contrary, one may show that all values of h from 0 to Z occur with equal probability for freely jointed connections between links. A more detailed study of the problem shows that the final result is unaffected by this assumption so long as n is large. The freely jointed chain model under consideration is an artifice also, but the form of the results obtained will be shown to apply also to real polymer chains. 

The introduction of vectors of constant displacement length to represent the individual elements, which actually vary in length, is rendered more plausible by inquiry into the effect of incorporating this artifice in the treatment of the freely jointed chain. In this case V = m H. Upon substitution of this expression together with n nlm in Eq. (17), the previous expression for / , Eq. (6), is recovered. Hence the calculated distribution is unaff ected by an arbitrary subdivision of the chain in this manner. We conclude that the value chosen for m in the reduction of the real chain to an equivalent freely jointed chain likewise is inconsequential (within the limits on m stated above). 

The enthalpy of decomposition, which is rather low compared with criterion C, in the CHETAH programme (see p.117), was determined by DSC and corresponds to 0.76 KJ/g at 230-260°C. In a confined atmosphere the decomposition conditions would be explosive. This reaction has been used many times because of its spectacular aspect. This is why it is called Vesuvius fire by artificers and green volcano by lecturers. These demonstrations should be stopped because of the detonation risks they represent as well as chromium (III) oxide toxicity. 

Carothers was regarded as Illinois best organic chemistry student, equally good at physical chemistry, mathematics, physics, and laboratory techniques. Moreover, as Adams put it, Carothers was a lovable man. Despite his obvious talents, he was without artifice or pretense. Nevertheless, when Carothers savings ran out after a year, he had to leave Illinois to earn money teaching at the University of South Dakota, where the ever-faithful Pardee had arranged a position.

Even in urban areas the foods for sale were chiefly raw, unprocessed, and of local origin. By 1900, America was substantially urbanized, and much of the food sold in the cities was processed— refrigerated, canned, chemically preserved—by large firms doing business on a national scale. With this growing distance between producer and consumer came an increasing opportunity for artifice in the food supply. The unannounced substitution of a cheaper food for a more expensive one and the use of added substances to preserve and color, although practiced since antiquity, became more widespread, and new techniques, such as the use of synthetic colors prepared from coal tar, became common (1). 

Figure 9 provides a comparison of the predictions of empirical methods with Wormald s data for a 50/50 mole percent mixture of steam and methane. As can be seen, the frequently used artifices of calculating mixture enthalpies by blending the pure component enthalpies at either total or partial pressures are very inaccurate. Likewise, the assumption of ideal gas enthalpy for the real gas mixture, equivalent to a zero enthalpy departure on the diagram, is an equally poor method. 

Olmsted was so skillful at concealing the artifice that both the projects he had so brilliantly constructed and the profession he had worked so hard to establish became largely invisible. Today the works of the profession of landscape architecture are often not seen, not understood as having been designed and deliberately constructed, even when the landscape has been radically reshaped. ... 

The exact history of the discovery of iron is unclear. There is a reference in the Old Testament mythology of Genesis that refers to a descendant of Adam as an iron instructor of every artificer in brass and iron. Archeological artifacts made from smelted iron are known from about 3000 bce. Iron seems to have been introduced as the last stage in the age of met-... 

Adam Smith s Wealth of Nations, Book V, Ch. 1, contains an extended account of the Militia. It is there said Men of republican principles have been jealous of a standing army as dangerous to liberty. In a militia, the character of the labourer, artificer, or tradesman, predominates over that of... 

LAMP-FIRE represents the Water, or Mercury of the Philosophers, but not the fire in an ordinary lamp, as some have erroneously concluded following Artephius, who states We properly have three fires, and without these the Art cannot become perfect. The first of these is the Feu de Lampe, which is a continuous, humid, vaporous, aerial fire. It takes considerable artifice to find it.. . . Our water [as Lamp-Fire ] is not vulgar mercury it is instead a living water, it is bright, brilliant, white as snow, hot, humid, aerial, vaporous and digestive. It is the heat thrown off by a lamp with has been attended to gently and, as it is temperate, so will it encircle the matter and cook it. ...
