This has eventually resulted in increased demand for building materials and wood fibre products.
Generally, this can be achieved by making use of wood instead of either fossil fuels or non-wood materials, such as steel, aluminium and concrete materials.
The availability of timber and other wood-based materials locally in large quantity, particularly in the Southern part of Nigeria facilitates high preference for the choice of these materials for finishes.

At last, this model was applied in forecasting the demand for emergency materials in disaster.
Thus, applying the research result of the previous part of this article, we can establish a prediction model of the demand for emergency materials in disaster on the basis of different types of whitenization weight functions, therefore forecasting the demand for emergency materials in real time to provide the reference for emergency organizations and reduce the lost of citizens’ fortune and lives and the harm on the development of economy and society.

Introduction The interior cracks defect of brittle material cause high concentration of stresses which may affect the mechanical properties of materials.
For actual materials, there are several of complex cracks in heterogeneous materials (e.g., rocks) in some cases which can not be simply reduced to two dimensions.
They use different methods to make artificial crack in brittle materials such as different transparent casting resin, cement and mortar samples by changing the location of the original cracks to simulate the destruction of brittle materials.
We choose PMMA as the test materials.

All charge materials: metal parts, slag-forming agents and deoxidizers are used dry, free of oils and inclusions.
The dimensions of the charge materials pieces should be no more than 50×200×250 mm.
Specified size of charge materials.
Additionally, the slag is deoxidized with granulated aluminum, sawdust or other aluminum-containing materials.
