Vendor to supply the civil foundation drawing for the boiler full of water with all fittings and water filled in and purchaser to make civil foundations for the maximum weight. Location of foundation bolts and sliding (roller) supports shall be as per drawing given by boiler manufacturer. 

Foundation drawings—diagrams containing concrete, wire mesh, and steel specifications that identify width, depth, and thickness of footings, support beams, and foundation. 

Information normally excluded from P I diagrams includes electrical wiring (normally separate electrical diagrams must be consulted), nonprocess equipment (e.g., hoist, support structures, foundations, etc.) and scale drawings of individual components. 

Horizontal cylindrical tanks should be installed on brick or reinforced concrete cradles with a downward slope of 1 in 50 from the draw-off end towards the drain valve, as shown in Figure 18.1. Cradles should be constructed on foundations adequate for the load being supported and the type of soil. A reinforced concrete raft equal to the plan area of the tank, and of adequate thickness to bear the load, is normally suitable for all but the weakest soils. Cradles should not be placed under joints or seams of the tank plates and a layer of bituminized felt should be interposed between the cradle and tank. The height of the tank supports should provide at least 450 mm space between the drain valve and ground level to allow access for painting or draining the tank. 

This work was supported by the Industrial Consortium of the Whistler Center for Carbohydrate Research, the Purdue Research Foundation, and the National Science Foundation (MCB-9219736). Akella Radha and Andrea Giacometti are thanked immensely for their generous help that culminated in the successful compilation of the tables and an artistic rendering of the drawings. 

This decade also saw the first major developments in molecular graphics. The first multiple-access computer was built at MIT (the so-called project MAC), which was a prototype for the development of modern computing. This device included a high-performance oscilloscope on which programs could draw vectors very rapidly and a closely coupled trackball with which the user could interact with the representation on the screen. Using this equipment, Levinthal and his team developed the first molecular graphics system, and his article in Scientific American [25] remains a classic in the field and laid the foundations for many of the features that characterize modern day molecular graphics systems. 

Lactulose is the foundation of pharmacologic therapy to prevent and treat hepatic encephalopathy. It is a non-digestible synthetic disaccharide laxative that is hydrolyzed in the gut to an osmotically-active compound that draws water into the colon and stimulates defecation. Lactulose also lowers colonic pH, which favors the conversion of ammonia (NH3) to ammonium (NHf).48 Ammonium is ionic and cannot cross back into systemic circulation it is eliminated in the feces. Lactulose is usually initiated at 15 to 30 mL two to three times per day and titrated to a therapeutic goal of two to four soft bowel movements daily.20 49 50... 

In this respect, current state-of-the-art ends up in a draw. This book makes a substantial contribution to the current literature on the analytics of polymer additives, follows up an earlier industrial tradition and lays a foundation for the future. It will be of great value to a broad readership comprising industrial and academic (analytical) chemists, polymer scientists and physicists, technologists and engineers, and other professionals involved in R D, production, use and reuse of polymers and additives in all areas of application, including manufacturers, formulators, compounders, end users, government legislators and their staff, forensic scientists, etc. 

The most common way radon enters a building is when lower indoor air pressure draws air from the soil, bedrock, or drainage system into the house. If there is radon in the soil gas, it will also be drawn in. Just as gravity will make water flow from a high elevation to a lower elevation, pressure differences will make radon-laden air move from an area of higher pressure to an area of lower pressure. For a variety of reasons, most buildings tend to maintain an indoor air pressure lower than outdoor air pressure. If cracks and holes in the foundation are open to the soil, radon will be drawn indoors. Radon movement by pressure differences is called pressure-driven transport. 

Figure 31.12 illustrates that a low-pressure area being developed beneath the slab will draw the radon out of the soil, up the pipe, and exhaust the gas outdoors. If the subslab material consists of tightly packed soil or contains large rocks, the pressure held may not extend to all areas of the soil surrounding the foundation, and allow radon to enter the home where the pressure held does not exist. One way of ensuring the proper extension of the pressure held is to install media beneath the slab prior to the pour that will allow the easy movement of the air, thus helping to extend the pressure held. 

Theoretically, a gastight barrier could be placed between the soil and foundation to eliminate radon entry from the soil. Like many other building details, it is much easier to draw such a detail than to actually install it. Many materials form effective retarders to gas transport. The problem is effectively sealing cracks, joints, and penetrations. As anyone who has tried to build an airtight house can tell you, it is not as easy as it seems. 

A common type of forgery consists not of newly made objects, but of the remains of old ones, which serve as the foundation for additional new work. The advantages of this method are obvious since the basic materials of this type of forgeries have all the marks of age and authenticity, the objects seem to have been restored, and the borderline between restoration and outright forgery is difficult to draw. Occasionally, enthusiastic restorers create new styles by working derivatively from small fragments many "ancient" bronzes and ceramics are faked in this way, sometimes supplemented by additional parts (Woolley 1962 Schmitt 1959).

If specified, the vendor shall test to demonstrate that the pump and its baseplate assembly, anchored at foundation bolt hole locations, are in compliance with 6.3.5. The pump casing shall be subjected to moments MTc and MZc applied to either nozzle, but not both, such that the corresponding shaft displacements can be measured and recorded. MYc and MZc shall not be applied simultaneously to either nozzle. The shaft displacement measurements shall be absolute (not relative to the baseplate). For record purposes, the vendor s test data shall include a schematic drawing of test set-up, the calculated moment loads 0/Fcand MZc), and the applied moment loads and their corresponding displacements at the drive end of the pump shaft.
