However, this approach proved to be too complicated for engineering applications.
This version of the LA is aimed at solving engineering problems; therefore it was called the “engineering” version of LA.
This is one of the challenges for physics and mechanics of fracture of irradiated materials.
A function to describe the temperature dependence of number of the crack nuclei in the “characteristic” volume is a key element of the engineering version of LA.

Two construction units shirked mutually the shares and liabilities of interface materials purchases and construction.
The sub-contract management in EPC engineering is a systems engineering.
In order to ensure the smooth implementation of the project, the general contractor of EPC engineering would monitor the key nodes of sub-contract control from an overall point of view.
For example, the general contractor don’t coordinate with some works in time, with insufficient investment in EPC engineering of human, financial and material resources.
Increase the level of engineering claim processing.

Materials for Devices in Life Science Applications G.
The unprecedented technology advancements in miniaturizing integrated circuits, and the resulting plethora of sophisticated, low cost electronic devices demonstrate the impact that micro/nano scale engineering can have when applied only to the area of electrical and computer engineering.
The integrated life chip technology requires the integration of multiple materials, phenomena, technologies, and functions at micro/nano scales.
To addresses the broad issues of understanding the material and process requirements from an integrated life chip application perspective, we will examine how to modify microfabrication techniques and innovate process conditions for depositing, patterning, and enhancing the functions of these materials.
Technologies for performing automated, high-throughput protein crystallization screening, and strategies for rational control of protein crystal growth are key engineering challenges for structural genomics and for structural biology in general.

It was found that grain size is a key microstructural factor affecting physical and mechanical properties of the materials [3-4].

The demands made on structural composite materials in modern design are increasingly stringent.
Understanding Structural Integrity (SI) provides the key to the successful design, certification, and safety of large composite structures and engineering composite materials.
Using these tools to determine constitutive equations relies on knowledge of the rules of materials behaviour.

Engineering Geologic Condition in Karst Area Strata in karst area are as following.
Shallow karst cave has more filling materials and deep one has less.
If settled material is too thick, engineering pile safety cannot be guaranteed.
For example, to calculate engineering pile length according to presumed wave speed and transmission time of concrete.
