The bleeding of cementitious materials corresponds to the settlement of the granular skeleton accompanied by the accumulation of water at the surface (bleed water).Part of this water (internal bleeding) remains trapped under the aggregates (sand or gravel) or the reinforcements.The excess of this trapped water can weaken the bond between the cement

Suppose that G is a simple undirected connected graph.Denote by D ( G ) the distance matrix of G and by T r ( G ) the diagonal matrix of the vertex transmissions in G, and let α ∈ [ 0 , 1 ].The generalized distance matrix D α ( G ) is defined as D α ( G ) = α T r ( G ) + ( 1 − α ) D ( G ) , where 0 ≤ α

Perovskite solar cells (PSCs) are third-generation photovoltaic technology that has gained a lot of attention due to its technological and economic advantages.The PSCs are characterized with low cost, high absorption, long copyright diffusion length, and low fabrication temperature.To model the performance of PSCs, a new dynamic model is proposed t

Aims: The study was performed to estimate transconjunctival penetration of mitomycin C (MMC) to Tenon′s tissue following application over the intact conjunctiva before routine trabeculectomy.Settings and Design: Institution-based case series.Materials and Methods: In 41 eyes of 41 patients, MMC (0.4 mg/ml for 3 min) was applied over the inta
