However, as a historical thesis about the origin of marriage, the idea that monogamy provided women with needed material support has been debunked.
The oblique helicoidal (heliconical) state has been predicted by Meyer and de Gennes to occur in the applied electric field in a cholesteric in which the elastic constant of bend K3 is much smaller than the elastic constant of twist.[ 20, 21] For a long time, the effect could not be explored because of lack of materials with the needed elastic properties.
As a means of increasing long term stability a base plate material is needed with a good thermal conductivity (TC) combined with a low coefficient of thermal expansion (CTE) matching the ceramic insulator.
Sergeant Kenny's specific task is to help the rescue teams cope with hazardous materials; if needed, he would round up equipment or information, he said: "Get whatever they need to get the job done".
The journal covers experimental and theoretical aspects of materials and prototype devices for sustainable energy conversion, storage, and saving, together with materials needed for renewable fuel production.
The mines in the Pilbara date from the 1960s, when they began supplying Japan with the raw material it needed to build its cities and industries.
14 In dielectric elastomer research, materials are needed with a wide range of elastic moduli, combined with very low viscosity and electrical conductivity, high dielectric constant and breakdown strength.
It acknowledges that no institution alone can meet the human and material capacities needed to deal effectively with disaster.
Materials are needed with a near-zero coefficient of thermal expansion; in other words, they have to be thermally stable and should not expand and contract when exposed to extreme changes in temperature.
Initially, creator Alan Ball artfully balanced source material with the need for it to work as a TV show.
