要控制

Walter Lauriksgs dunkel bleibt und nicht selbst wiederum thematisiert wird. Damit verliert die moderne Wissenschaft ihren lebensweltlichen Sinn, von dem sie doch einst ausgegangen ist, aus den Augen. Denn eine Wissenschaftstheorie auch der Landschaft muss sich damit beschäftigen, wie sie adäquat damit umgehen möc

The morphology of flexible polyurethane matrix polymers,d in Fig 4.2. The reaction products, which include urethanes, ureas, amides, allophanates, biurets, carbodiimides and isocyanurates, subsequently associate to generate an auxiliary network. The latter associations generally lead to a polymer having multiphase molecular morphology.

Thermal ageing,ease of the thermal conductivity λ due to outward C0. diffusion followed by a fast increase of thermal conductivity in the first period (air in) and a slower but still important one in the latter stages (CFC-11 out). In the first period (1–10 weeks) a dissolution of the high molecular blowing agent

Impact response,within the cells provides pneumatic cushioning, which happens to be of the correct magnitude for many applications. Open cell foams, which have been discussed in Chapter 8, do not have this energy absorption mechanism, although there may be pneumatic losses as the air passes through restricted holes

Acoustic characteristics of low density foams,t theory allows in a very general and rigorous way the description of sound propagation in porous materials. This theory has been used amply, including in underwater acoustics and sound propagation through liquid filled rocks. Recently, the Biot theory has been used to calculate the acoustic propert
