Bridge building

My chagrin was bottomless and I fled, dizzy with embarrassment. So much for my bridge building efforts toward normal science. 

Colleagues often inspire one another in their professional undertakings. On comparing the materials collected after 2001, it is clear that the process of intellectual bridge building develops with time. 

Iron and steel became the stuff of big and visible things—ships, bridges, buildings. 

Composite materials have been acclaimed as the Materials of the Future. A key question is whether composite materials will always remain the materials of the future or if the future is here. Advanced polymer composites, once destined for stealth military aircraft or aerospace uses, are beginning to be used in down-to-earth structures, such as bridges, buildings, and highways. However, there are still considerable impediments to wider use, and composite manufacturers need to make great strides in the development and manufacturing of composite materials. 

The men who face these challenges were a new type of businessman.. .. The pioneers of modern management... were all trained civil engineers with experience in railroad construction and bridge building before they took over the management of the roads. 

Corrosion is the deterioration of a metal by oxidation, such as the rusting of iron in moist air. The economic consequences of rusting are enormous It has been estimated that up to one-fourth of the iron produced in the United States is used to replace bridges, buildings, and other structures that have been destroyed by corrosion. (The raised dot in the formula Fe2C>3 H20 for rust indicates that one water molecule is associated with each Fe2C>3 in an undefined way.)... 

Since steel is the main structural material for bridges, buildings, and automobiles, controlling its corrosion is extremely important. To do so, we must understand the corrosion mechanism. Instead of being a direct oxidation process, as we might expect, the corrosion of iron is an electrochemical reaction, as illustrated in Fig. 11.17. 

Collisions with atomic clusters represent a relatively new branch of collision physics as compared to the well established fields of ion-atom collisions [1] and ion-solid interaction [2]. The study of cluster collisions is of particular interest and importance because it offers the possibility, to tackle bridge-building questions (like the transition from individual excitations in the elementary ion-atom collision to the macroscopic stopping power in solids) as well as fundamental problems (like phase transitions in finite systems). 

Oxyacetylene welding is used to repair metal structures, including bridges, buildings, and even the Statue of Liberty. Calculate AS° for the combustion of 1 mol of acetylene (C2H2). 

Mg is the mass of the bridge building material and Mp the mass of the agglomerate building particulate solids, pg and Pp are the densities of the respective solid materials, 1 - s is the relative volume of the particulate solids building the agglomerate, e is the specific void volume (porosity) of the agglomerate, and is the fraction of voids in the...

The linking of plastics molecules by primary valencies into a mainly three-dimensional network. Suitable polymers can also be cross-linked chemically, by adding corresponding bridge-building molecules...
