Желание человека стать владыкой было безумным. Но он им стал и вскоре проиграл битву и теперь должен отдать свои владения чужаку, или же рискнуть всем и выставить в мясорубку жестокой игры богов свой единственный шанс - необученный и еще даже несформированный Тандем.

The Wargames Research Group (WRG) is a British publisher of rules and reference material for miniature wargaming. Founded in 1969 they were the premier publisher of tabletop rules during the seventies and eighties, publishing rules for periods ranging from ancient times to modern armoured warfare, and reference books which are still considered standard works for amateur researchers and wargamers.

Nitrogen oxides are common by-products of fossil fuel combustion and are one of the most significant types of air pollution. The nitric oxides react with UV radiation to form oxides of nitrogen, ozone and acids. The nitrogen oxides can have considerable impact of the life of polymers in the environment and can be responsible for failure of polymer products, so it is important to know how these effects will manifest. Most of the earlier studies of the effect of nitrogen oxides on polymeric materials have involved the determination of changes in the average molecular weight and mechanical properties, as well as changes in chemical structure using infrared spectroscopy. However, these characteristics provide no direct information on the mechanism of intermediate stages of the complicated processes of polymer degradation under the action of these aggressive gases. In this book, novel results obtained by other physicochemical methods especially electron spin resonance spectroscopy are considered for various polymers. The influence of different functional groups on the mechanism of interaction of nitrogen oxides with polymers are discussed. The features of ion-radical initiation of conversions of polymers by dimers of nitrogen dioxide are also considered. Various other techniques for studying these interactions are also discussed. This handbook will be of interest to all those who produce polymer products that are likely to spend their life in an outdoors environment. It will also be useful to the manufacturers of raw materials used in these products. Technicians who are involved in material testing will also find a wealth of information about testing for the effects of ozone on polymers.

Самоучителей вождения существует много, но среди них нет ни одного столь полезного, как тот, который вы держите в руках. Вы узнаете еще и о том, чему не учат в автошколах: об «автоподставах», о грамотном поведении при ДТП, о том, что делать, если вашу машину утянул эвакуатор, о способах вождения неисправного автомобиля, о правилах ночного вождения, о «тайном языке» водителей и о многом другом.

Museum Monograph No. 3. One of the most interesting and valuable groups of artifacts to be found at abandoned military posts and camps are the metal uniform objects lost or discarded by the soldiers. Brought to the surface by wind and rain or by archaeological investigation, these buttons, branch insignia, and buckles have real aesthetic interest for the collector. They also have historic importance, along with documentary sources, as a means of dating the location, and in some cases, identifying the branch or unit there stationed. Uniform buttons are most frequently recovered. Light brass buttons, no matter how well sewn to the uniform, were apparently easy to lose. Considerable numbers have been discovered in the trans-Mississippi West, both by casual explorers and by historical archaeologists. Because of the number of troops who passed through or were stationed west of the Mississippi from 1846 through 1902, and the vigorous duty they performed, it is not surprising that so many buttons were left behind. The same reasons apply to the insignia and belt buckles which have also appeared, although they are found in less quantity. On occasion, a large concentration of belt buckles or other items are found together in a small area in the ground, sometimes mutilated. Obsolete items were often so disposed of by the post quartermaster. While not all of the types of metal uniform objects uncovered are treated here, the most common finds are described in enough detail to make field identification possible.
