Infrastructure bridge

There are perhaps hundreds of miscellaneous unsaturated polyester resin construction applications. These would include window frames, doors, cabinet enclosures, electrical boxes, etc. In addition, recent developments bode well for unsaturated polyesters in construction markets. Concrete rebar, bridge construction and general infrastructure repair are examples of growing construction applications. [Pg.711]

Whether we are referring to music or high-density metals, heavy metal brings to mind a material that plays an essential role in almost every phase of our daily lives. We use metals not only for jewelry but as the structural material for transportation vehicles and most buildings and bridges, and as conductors of electricity and heat. Our entire infrastructure depends on metals. [Pg.274]

Construction. Polymeric materials such as adhesives, sealants, and composites have been used considerably in the last several decades for the construction, repair, and rehabilitation of our transportation infrastructures. Even though most processes were experimental until recently, they have evolved to the point where many are now standardized and well accepted. Table 1.6 hsts several common applications for advanced polymeric materials (as well as the polymeric resins that are most commonly employed). In the construction or repair of roads and bridges, epoxy adhesives have primarily been used for bonding concrete and for bonding stiffening members or repair structures to degrading concrete facilities. [Pg.13]

The scope for quality assurance embraces all components within the Local Area Network (LAN), e.g., the bridges and routers and the interface to the public telephone and telecommunications carrier (PTT) but not beyond this. The public domain infrastructure, e.g., Internet that connects site LANS, is not within the control of the pharmaceutical organization. The PTT is entrusted to pass the signal without error to the router at the destination network interface. It is not recommended to qualify the PTT ... [Pg.843]

The second factor to be considered is the target attractiveness. Terrorists tend to consider national monuments, major cultural, political, and sporting events, and the financial sector to be particularly attractive, as an attack on such a target is viewed as an attack on their enemy s entire way of life. Likewise, key infrastructure components such as key bridges, tunnels, highways, and railways are more attractive. Finally, the public s fear of chemical and petroleum facilities may make these more attractive targets, more so if materials in the facility have potential off-site consequences if released. [Pg.303]

Step 5 Determine What You Need to Protect. An asset is anything the facility owns or employs that could possibly be exploited by a terrorist. In a chemical plant, physical assets include tanks, reactors, and warehouses. Bridges, trains, power lines, herds of cattle, and assembly lines are examples of assets in other sectors. In all sectors, people are assets, as are computer infrastructures. In the asset identification step, you need to identify everything under your control that you may need to protect. [Pg.304]

The second law describes the entire universe. On a more personal level, we all fall victim to the law of increasing disorder. Chaos in our room or workplace is certainly not our intent It happens almost effortlessly. However, reversal of this process requires work and energy. The same is true at the molecular level. The gradual deterioration of our cities infrastructure (roads, bridges, water mains, and so forth) is an all-too-familiar example. Millions of dollars (translated into energy and work) are needed annually just to try to maintain the status quo. [Pg.208]
