Preparation of Porous Multi-Channeled Chitosan Conduits for Nerve Tissue Engineering Q.
Materials Chitosan (degree of deacetylation = 83.7%, Mη =1.8 × 106) was purchased from Qingdao Haisheng Co (China).
Neuroblastoma cells (N2A, mouse) were used to evaluate the nerve cell affinity of the materials.
The results demonstrated that the Multi-channeled chitosan conduits were desirable for the application in nerve tissue engineering.

Singularity-reduced Integral Representations for Discontinuity in Smart Materials Jaroon Rungamornrat1, a and Teerapong Senjuntichai2, b 1, 2 Department of Civil Engineering, Chulalongkorn University, Bangkok, Thailand 10330 a Jaroon.R@chula.ac.th, bfcetsj@eng.chula.ac.th Keywords: Smart materials, Piezoelectric, Piezomagnetic, Integral relations, Cracks, Dislocations, Singularity-reduced, Weakly singular, SGBEM.
Introduction In the past two decades, smart materials have gained significant applications in various engineering practices (e.g. smart structures, nondestructive testing devices, electronic devices, sensors and actuators).
Complexity of smart materials is due primarily to the coupling feature of the governing constitutive law.
Three well-known classes of smart materials that commonly encounter in applications are piezoelectric, piezomagnetic, and piezoelectromagnetic materials.
Materials in the first class (e.g.

Muddy water seepage theory's applications in engineering practice give full expression to its theoretical significance and application value.
In recent years, people according to many practical engineering problems such as plain reservoir seepage-proofing control,seepage stability analysis, have carried out a series of detailed and quantitative researches, which not only further improves the percolation theory but also better guides the engineering practice problems.
The achievement of these study still on the stage of grope and practice and accumulating experience is not very available for solving the muddy water seepage problems in geotechnical engineering.On the basis of muddy water seepage theory, whether in conformity with the engineering practice is the basis of its research value.

The paper presents details concerning the basis of the technology, process parameter settings and their responses, and reviews the properties of common FDM engineering/bio-materials and the available methods applied for improving their performance.
Improving the polymers is essentially based on the correct selection of additive materials, which can particularly enhance the key property/properties in the matrix material.
FDM materials Based on the field of the application FDM materials can be classified into two brands; engineering and medical materials.
Engineering FDM materials By tracking the current technical characteristics of FDM technology, it will be noted that there are some limitations that restrict the variety of material which can be processed by this technology.

The traditional engineering education overemphasizes the specialization, thus separated engineering itself.
First step is “Taste”： select some typical material in discipline to form the theme, in the engineering practice or the experiment environment, provides the engineering work frame construction, introduced the basic individual and interpersonal ability which project needs.
Cultivate engineering spirit and consciousness and preliminary engineering “experience”.
Introduction of third professional institution evaluate the whole process of engineering, is key means to ensure quality of engineering education.

Introduction In hydraulic and hydropower engineering construction, varieties of resources are consumed, including labor, raw material, circulation material, construction equipment, temporary facility, information and service.
However, budget quota in hydraulic and hydropower engineering is a measuring standard, which can reflect resource consumption of engineering construction in a certain time[3].
Through comparison of the labor, material and mechanical loss in budget quota of hydraulic engineering, the differences of budget quota are analyzed clearly[4].

Following measures would be taken in engineering design. (1) Reasonable arrangement of noise sources.
To take noise elimination measures at inlets and outlets of wind. (4) The key was to control noise from power station in which to lay sound-absorbing material on the wall and choose sound insulation windows and doors. (5) The main noise source-power station would be set in the south of main buildings in engineering design with more than 40 m distance from factory boundary and planting trees around the factory.
