The fluid flow through porous structure is a phenomenon which occurs in a range of technological processes and it is a subject of a wide interest in Materials Science for all the time.
Moreover, if we evaluate current scientific trends in global, and Materials Science especially, nanomaterials became the subject of the study in all branches of science and research.
Revolutionary material of the 3rd Millenium, nanofibre and nanoparticle materials, and development of the porous materials with difficult (multilayer) internal structures requires a deeper reassessment of theoretical techniques and methods, used for a fluid flow description so far.

Thermal and moisture transport in fibrous materials.

Introduction The belt conveyer is a kind of important equipment conveying continuously modern materials.
In order to increase the transportation materials' inclination angle, we must increase the friction force between the material and belt as well as material and material.
B -belt width; A -material cross sectional area; H -material depth; W -the biggest aperture section; φ-the material's stack angle; α-groove angle; 1l -middle supporting roller's length, mm. 2.
The chucking power of the belt to the material has been increased, thus the friction force between the material and the belt as well as the material and the material have also been increased, so it can realize the great inclination angle transportation.

The current study is focused on WC-Ni cermet coatings, materials that are extensively used in applications requiring wear resistance.
The original applications for HVOF were wear components in GTEs, such as shafts and bearing journals.
It is limited for high temperature materials such as oxides, most of which cannot be melted in the flame.
Because of the most common application of nanostructured materials in the thermal spray industry is for WC-based cermets, the amount of work being done related to this material is increasing quickly.

Eissa Physics Department, Faculty of Science, Beni-suef University, Egypt mostafa.eisa@science.bsu.edu.eg Keywords: Alpha Particles, CR-39 Polymer, Optical Band Gap Energy, Track Etch, Urbach Energy Abstract The track etch detector, CR-39, in common use is the most sensitive to recording charged particles.
Thus, the present work was verified by the UV-vis spectra of CR-39 polymer materials which irradiated with different alpha particle energies (2.17-3.95 MeV) at a constant fluence and different etching times (1.500, 3.00 and 6.00 hrs).
The optical absorption method used for the investigation of the optically induced transitions which can provide information about the band structure and energy gap in crystalline and non-crystalline materials.

During the evaluation of the datasets it was proven, that the well known canonical evaluations could not be used with high reliability for all the measurements, for all the materials and for all the geometry used.
The code used for the numerical simulation (Fluent) was able to handle the heat conductivity, the liquid flow, the complex material parameters changes and the used geometries as well.
The thermal diffusivity parameters of solids had been measured at the ARCS-AMTT (Aerospace Materials Technology Testhouse) and had been funded by the contract HPRI-CT-1999-00024 of the Improving Human Potential program of European Commission.

Materials and methods Experimental data The material used in this study was harvested from a triploid clone trial established in 2004 in northern China, on agricultural soil with typical site fertility conditions for Chinese white poplar.
Thereafter, fiber length and fiber width were measured using the LW Fiber Tester (Tianjin University of Science & Technology), which is based on image analysis.
