Introduction Creep and stress relaxation are the inherent mechanical behaviors of stainless steel bolting materials at elevated temperature in a power plant.
The relationship between the residual stress and time during stress relaxation has been derived from the creep equations to analyze the stress relaxation curves of various different materials.
(1) where A, σ0, n, α, β are material parameters, is the creep strain rate, and σ is stress.

Mixed flowing vibrating drying processes The mixed flowing vibrating drying processes is shown in Fig. 1, The mixed flowing vibrating drying process is shown in Fig.1, the wet materials are fed from the top of the system, dispersing materials due to the action of multi-layer drying screen, small particles less than the screen pore can drop down vertically, other coarse materials larger than the screen pore will move loosely and horizontally along the surface of screen and spilled into the next one.
Vertical thermal current contacts with materials through the air hole on the surface; horizontal thermal current slides among the screens with variable flow-rate and acts on the materials directly.
Thickness of the materials mixed with the hot air in the process after several times dry processes, most products are discharged from the bottom, a small amount of the dust goes into the dust collection systems, which will be also recycled as the final product. 1.Hot stove 2.Settling chamber 3.Adjustable fence 4.Chimney 5.Intake flue 6.Hot air blower 7.Dryer 8.Coal feeder 9.Coal machine 10.Bag filter 11.Unloader 12.Exhaust fan Fig. 1 Mixed flowing vibrating drying processes The mixed flowing vibrating dryer can handle different materials mixed by different particle size of wet materials.

Logistics dependencies, it describes the demand and supply of materials between the Agent and the transfer process.
Main production planning agent can obtain the order form, then according to product maturity, capability and availability of materials, use of different degree levels of partners competition to generate different manufacturing plans.
The manufacturing plan will be used by material planning and site control agents to perform the production process.
Material planning agent has two functions, one is how to calculate the materials required for manufacturing process plans, including the components assignment inventory, or purchasing the components from supplier's.
Another is how to generate production plan by offering availability information of the materials required.

The increasing importance of materials from renewable sources has put starch and chitosan in the spotlight, especially due to their biological properties, which have been exploited in many applications.
It is also be determined by the hydrophilic groups in these polymer and natural polymer materials.
It is noticed that exposure of these material to gamma irradiation lead to the cross linking and degradation reactions.

Introduction Magnesium and magnesium based materials is one of the most promising mobile hydrogen storage candidates because of their high hydrogen storage capacity (7.6 wt.% for pure Mg), light weight and low cost.
A lot of approaches have been developed to improve absorption/desorption kinetics of Mg-based materials.
Experimental Procedures Pure elemental powders of Mg (-325 mesh), Ni (-325 mesh) and Nb(-325 mesh) with the purity level of 99% were used as starting materials mixed in various compositions and charged into the stainless steel vials.
