Diehl himself worked in the furnace room, a one-floor building on the northern end of the grounds. There he prepared mercuric substances, including corrosive sublimate (mercuric chloride) silver nitrate heavy oil of wine (ethereal oil) solution of chlorinated soda (Labarraque s solution) potassium carbonate potassium acetate citrate of iron and quinine, of which immense quantities were in constant requisition various ferric (iron) solutions syrup of squills and a few other items. He concluded with the following summary ...

For simple systems, as in that of a multi-floor building, the influence coefficients of the stiffnesses are directly calculated from the stiffnesses of the various floors. A framed multi-floor building whose girders can be considered rigid in comparison with the columns (Fig. 15-15) is particularly simple. Here, the reaction forces on a floor are different from zero only for the unit displacement of the immediately adjacent floors (i.e. the coefficients k,y with i and j different for more than one unit are equal to zero).

My active life and work were unexpectedly affected by two serious illnesses that I fought in 1979 and 1982. We spent the first two years in TA in temporary laboratories in the basement of an old science building, where I also had my office on the ground floor above the... 

One method for measuring the temperature of the sea is to measure this ratio. Of course, if you were to do it now, you would take a thermometer and not a mass spectrometer. But how do you determine the temperature of the sea as it was 10,000 years ago The answer lies with tiny sea creatures called diatoms. These have shells made from calcium carbonate, itself derived from carbon dioxide in sea water. As the diatoms die, they fall to the sea floor and build a sediment of calcium carbonate. If a sample is taken from a layer of sediment 10,000 years old, the carbon dioxide can be released by addition of acid. If this carbon dioxide is put into a suitable mass spectrometer, the ratio of carbon isotopes can be measured accurately. From this value and the graph of solubilities of isotopic forms of carbon dioxide with temperature (Figure 46.5), a temperature can be extrapolated. This is the temperature of the sea during the time the diatoms were alive. To conduct such experiments in a significant manner, it is essential that the isotope abundance ratios be measured very accurately. 

Residential Construction. Owing to rising energy costs, the cost and low thermal conductivity are of prime importance in wall and ceiling insulation of residential buildings. The combination of insulation efficiency, desirable stmctural properties, ease of appHcation, abiHty to reduce air infiltration, and moisture resistance has led to use of extmded polymeric foam in residential constmction as sheathing, as perimeter and floor insulation under concrete, and as a combined plaster base and insulation for walls. 

Uses. In architectural and industrial appHcations vibrational isolators are used to reduce transmission of vibration into building stmctures from rotating or reciprocating machinery, such as ventilating fans, pumps, chillers, industrial machinery, and the piping and ductwork coimected to this equipment (6). Vibration isolators also can be used to isolate vibration-sensitive equipment or noise-sensitive areas from sources of vibration. Examples are special pneumatic isolators to protect electron microscopes, and isolators used to support floating concrete floors in recording studios. 

These foams are used for board stock in commercial and industrial buildings as insulation for internal cavity and external walls, roof, floor, and foundations. Spray-appHed foam, covered subsequently with one of a variety of protective coatings, is widely used for large roofing appHcations and has limited use as external walls. Eor residential buildings, the principal use is as external sheathing board. 

Bisphenol F epoxy resins are used in high-soHds-high-build systems such as tank and pipe linings, industrial floors, road and bridge deck toppings, stmctural adhesives, grouts, coatings, and electrical varnishes. Bisphenol F epoxy resins are manufactured in Europe and Japan. 

Consider the need for fire walls, solid floors, etc. in building design and construction... 

Wherever the rising mains crosses through a floor of the building, fireproof barriers are provided as shown in Figure 28.3(b) to contain the spread of fire to other floors.
