Internal stresses in the base/coating region resulted in severe deterioration of the durability of steel parts, as identified by static or sign-variable fatigue tests.
One of the most dangerous impurities in metals is hydrogen, HA by the steel melting processes causes occurrence of flakes in steel, "hydrogen illness" in Cu, porosity in Al and their alloys etc.
Arkharow et al revealed that an increase in Pd content from 0.03 % up to 0.5 % in steel 40ХН leads to a decrease of the quantity of hydrogen, desorbed from steel at room temperature from 4.7 mL/100 g (without Pd) up to 3.8 mL/100 g at 0.4…0.5 % Pd.

Introduction Since the first effort made by Plevris et al in 1995 [1] to assess the reliability of FRP-strengthened concrete structures, it has been gradually recognized that the application of probabilistic concepts is very essential for developing performance-based design methodology for these structures.

In literature, Hernan et al. reported that elevating the reaction temperature with an excess of both OH ions and oxygen gas was helpful to obtain purer Mn3O4.

TiO2 has special properties and is most frequently used as photocatalyst in water purification, for instance Abhang et. al. [7] who succeeded in purifying dirty water by using TiO2 photocatalyst.
This observation is also reported by Lin et.al [17] in their work.

Yuan et al. considered the bridge structure as a simply supported Euler-Bernoulli beam and developed dynamic load identification methods using modal superposition principle and least-squares method [5].
Chan et al and Yu and Chan performed a series of systematically researches and experiments on moving loads identification methods [6,7,8], which including Interpretive Method I [4], Interpretive Method II [9], Time Domain Method [10] and Frequency Time Domain Method [11], proposed a Moving Force Identification System (MFIS) theory for moving loads on the bridges, and analyzed the merits, weakness and applicability of these four methods.

In a comprehensive review on the sulphate attack, Hekal et al [6] pointed out that, in most cases, the loss of adhesion and strength, not expansion and cracking is the primary manifestation of sulfate attack.
