In this paper, we establish a limit theorem for triangular arrays of rowwise and pairwise mn-dependent random variables, where mn may approach infinity as n → ∞.

Additionally, a process for preventing mold growth on bamboo and wood materials was developed and the parameters were optimized using the Box-Behnken surface response correlation method.
