we prove that the class of profinite groups $g$ that have a factorization $g=ab$ with $a$ and $b$ abelian closed subgroups, is closed under taking strict projective limits. this is a generalization of a recent result by k.h.~hofmann and f.g.~russo. as an application we reprove their generalization of iwasawa's structure theorem for quasihamiltonian pro-$p$ groups.

STATEMENT OF PROBLEM Two problems found in prostheses with soft liners are bond failure to the acrylic resin base and loss of elasticity due to material aging. PURPOSE This in vitro study evaluated the effect of thermocycling on the bond strength and elasticity of 4 long-term soft denture liners to acrylic resin bases. MATERIAL AND METHODS Four soft lining materials (Molloplast-B, Flexor, P...

Fine-grained elasticity control of cloud services has to deal with multiple elasticity perspectives (quality, cost, and resources). We propose a cloud services elasticity control mechanism that considers the service structure for controlling the cloud service elasticity at multiple levels, by firstly defining an abstract composition model for cloud services and enabling multi-level elasticity c...

one of the main principles of resistance economy, is to support domestic production and limiting imports, especially in sectors where there is the possibility of import-substituting production .this requires adjustment of exact trade policies,and to achieve this, identifying the structure of imports demand function and also price and income elasticity of import demand is necessary.this necessit...

I study a model of portfolio choice over the life-cycle incorporating a transactions need of using monetary assets (MA), …xed costs of participation in non-monetary assets (NMFA) markets, and a realistics ‡uctuation of the return spread (the “opportunity cost”of holding MA). I estimate model parameters to match age pro…les of portfolio positions and market participation in a dataset consisting ...
