Modelling of Mass Transport in Porous Materials: Analytical Solutions and Analysis Antonio F.
In this paper approximate analytical solutions to mass transport equations in porous materials with both constant and non-constant diffusion coefficients are presented.
Many problems of practical importance related with mass transport in finite porous materials take place under periodic boundary conditions being the period being of few minutes to several months and years [2].

Load-Carrying Capacity Analysis for Sinusoidal Surfaces Hydrodynamic Bearing Jianxi Yang 1, a, Fayu Zhang 1,b Jianting Liu 1,c Jianfang Zhou 1,d 1 School of Mechatronics Engineering, Henan University of Science & Technology, Luoyang, 471003, P.R.
Compared with other journal bearings, the journal bearing with sinusoidal surfaces has stronger carrying capacity, smaller friction moment and longer life-span.
The result for surface harmonic characteristic journal bearing and general cylindrical journal bearing are shown in Tab.2.
The material for oil film bearing is generally Babbitt metal or copper.

FGM eliminates the macro interface in traditional hierarchical composite materials, so it can be used to achieve some specific function[1].
In general, the design guideline of the FGM is to choose two materials with different properties, and continuously change the composition or structure of the two materials with a certain pattern, which makes the FGM physical parameter to change follow the corresponding pattern along a certain direction.
In this paper, we select two materials as given in Table 1 to form the FGM.
