Influence of Drainage Holes on Condensation Risk and Air-tightness of Windows. An Experimental Case Study of Triple Glazing PVC Windows

open access: yesJournal of Asian Architecture and Building Engineering, 2017
Triple glazing windows incorporate drainage holes on glazing beads or gaskets to provide a path for condensed water from the inside to the outside. These holes are considered to be effective for draining condensed water but may decrease the air-tightness

To condense or not to condense? That is the question

open access: yesPhysics Letters B, 1992
Abstract We investigate the dependence of the pion mass in the nuclear medium with density and the condition for s-wave pion condensation. We base our approach on multiple scattering and the consistent use of the chiral off-mass-shell properties of the πN amplitude.

The Condenser Problem

open access: yesThe Annals of Probability, 1977
The condenser theorem in classical potential theory is studied within the framework of Markov processes and probabilistic potential theory. The condenser charge is expressed in terms of successive balayages of a capacitary measure.
