Use clean containers for mixing two-part adhesives. Well washed and dried plastic yoghurt, or other food, containers are suitable for most types. 

A chemically reactive adhesive that is suppiied in two separate containers for mixing immediately before use. 

We have found the principal axes from the equation of motion in an arbitrary coordinate system by means of a similarity transformation S KS (Chapter 2) on the coefficient matrix for the quadratic containing the mixed terms... 

Thermosetting Reactive Polymers. Materials used as thermosetting polymers include reactive monomers such as urea—formaldehyde, phenoHcs, polyesters, epoxides, and vinyls, which form a polymerized material when mixed with a catalyst. The treated waste forms a sponge-like material which traps the soHd particles, but not the Hquid fraction the waste must usually be dried and placed in containers for disposal. Because the urea—formaldehyde catalysts are strongly acidic, urea-based materials are generally not suitable for metals that can leach in the untrapped Hquid fractions. Thermosetting processes have greater utiHty for radioactive materials and acid wastes. 

Gases for mixing with argon, such as N2 and Xe, have been the subject of study for some time. Some new instrumentation tvill incorporate manifolds for making this process easier. Other plasma developments include microwave-induced plasmas with He to eliminate interferences from argon containing molecular species. 

Air handling unit A self-contained unit for the introduction or removal of air from a space. It consists of one or more of the following plant items heating or cooling coils, filters, fans, damper provision for mixing and recirculation, humidification controls, and acoustic treatment. 

The submitters mixed active anhydrous silica gel with water (12% v>/w) and stored it in a sealed container for at least 24 hours prior to use. A ratio of 60-80 g. of silica gel per gram of crude product was used for column chromatographic separations, and a column was chosen that would give a 10 1 height diameter ratio of adsorbent. Columns were wet-packed with distilled petroleum ether (b.p. 60-68c), and after the crude product had been applied a step-gradient was run rapidly through 2% vjv ether in petroleum ether, 5% ether, and 10% ether. The column was then eluted with 20% vjv ether in petroleum ether until the bromohydrin acetate was obtained. 

These properties, coupled with its relatively low cost, make copper one of the most useful metals in modem society. About half of all copper produced is for electrical wiring, and the metal is also widely used for plumbing pipes. Copper is used to make several important alloys, the most important of which are bronze and brass. Both alloys contain copper mixed with lesser amounts of tin and zinc in various proportions. In bronze, the amount of tin exceeds that of zinc, whereas the opposite is tme for brass. The discovery of bronze sometime around 3000 bc launched the advance of civilization known today as the Bronze Age. Because bronze is harder and stronger than other metals known in antiquity, it became a mainstay of the civilizations of India and the Mediterranean, used for tools, cookware, weapons, coins, and objects of art. Today the principal use of bronze is for bearings, fittings, and machine parts. 

Aseptic transfers are also avoided by the use of self-contained units where the spore strip and nutrient medium are present in the same device ready for mixing after use.
