background and objectives: making stacking gels for polyacrylamide gels in the laboratory by conventional methods is laborious and time consuming. considering the role of temperature in polyacrylamide gels with respect to electrical resistance and viscosity, we assumed that decreasing the temperature would cause an increase in electrical resistance and viscosity.  ultimately, a downward tempera...

«A perplexing lacuna in the story of Lope’s life is year 1588» wrote Rudolf Schevill 1941. He found particularly question whether or not El Fénix sailed with Spanish Armada. In 2015, RTVE attempted to fill this episode 2 their series ministerio del tiempo. Using Fax, Skype and an Internet search, “ministry” checks embarkation lists Armada horrified find that Lope de Vega has embarked on San Est...

This document defines and registers with IANA the new "fax" media feature tag for use with the Session Initiation Protocol (SIP). Currently, fax calls are indistinguishable from voice calls at call initiation. Consequently, fax calls can be routed to SIP user agents that are not fax capable. A "fax" media feature tag implemented in conjunction with caller preferences allows for more accurate fa...

The behavior of tethered polymers on gel/gel adhesion is studied with the single-chain mean-field ~SCMF! theory. It is shown that the gel surface structure, the gel/gel adhesion strength, the equilibrium gel/gel distance, and the detailed interface structures can be tailored by specifically designed tethered layers on gel surfaces. The SCMF theory allows to study the effect of various variables...
