Kappa vacua: Infinite number of new vacua in two-dimensional quantum field theory [PDF]
, 2022 We uncover an infinite number of vacua in two-dimensional quantum field theory, the Klein-Gordon field for simplicity, by conceiving a new mode that is classified by a real positive parameter $κ$. We show each mode has a distinct vacuum, say $κ$-vacuum. This new mode is a generalization of the Unruh-Minkowski mode.

Effect of alkaline extraction in reducing the Kappa number in ECF bleaching
, 2021 The acid hydrolysis stage (AHT) used in bleaching sequences of pulp, has as its main objective, the degradation of hexenuronic acids which are present in the pulp and can affect its brightness, reversal of brightness, among others. Despite the benefit of using the acid hydrolysis stage, the pH of this stage is not the most adequate, but when it comes ...
