Introduction and Background Membrane channel proteins are fundamental to biological function, and, as such, they are key targets for pharmaceutical therapy.
Here, we present a suite of technologies for simplifying membrane formation and improving membrane stability and longevity; these methods have the potential to facilitate the widespread study and engineering application of membrane channel proteins.
Though they have value in studies of cellular electrophysiology and have begun to be applied to drug discovery, they cannot isolate and control the environment of a single ion channel to the extent possible in a cell-free system, and they are not appropriate for ion channel-based engineering applications, such as sensors.
Materials and methods Freestanding microchannel fabrication PDMS microchannels were fabricated by molding a liquid 10:1 PDMS base:crosslinker mixture (Dow Corning) around 200 µmdiameter silver wires and curing at 60 °C for 2 hours.
Future devices will made of multiple materials to allow for both extracting and non-extracting regions.

Materials and Methods The study was conducted at the department of orthodontics, Jilin University College of Dentistry in collaboration with the Urumqi DW Innovative Infotech Co.
We assumed all materials to be homogeneous.
The materials’ mechanical parameters including elastic modulus and Poisson's ratio were adopted from a previous study (Table 1) [17].
All materials were designed to have small deformation under stress.

The strain hardening engineered cementitious composite recently proposed by Victor Li [1], is generally regarded as one of the most promising construction materials for controlling crack width of structural elements.
(a)UHTCC (b) concrete (c) steel bar Fig.1 Materials constitutive relationship For steel bar, stress hardening after yielding is not considered.
Based on cracking in the two materials concrete and UHTCC, there are two possible cases for computing the cracking moment of the composite beam.

As an important part of earthquake disaster relief, highway traffic system is the passage for rescue staffs, material transport and evacuation.
On one hand, key factors with great influence cannot be omitted; on the other, there shall not be too many evaluation indicators, which will bring great difficulties to evaluation and will not achieve ideal effect.
According to the survey and analysis to post-seismic highway subgrade damage characteristics and consulting of the Provisions on Evaluation to Seismic Damage Loss (Tentative), Post-earthquake Field Works series, Technical Guidance on Post-disaster Highway Recovery and Reconstruction of Wenchuan Earthquake, Classification of Earthquake Damage to Lifeline Engineering (GB/T24336-2009) and other related literature and data, the Paper classifies seismic damages of subgrade principal part, slope and retaining structures into 5 grades.

All of the processes mentioned above involve the use of the Kroll process [9] as a basis for obtaining metallic titanium from titanium raw materials (ilmenite or rutile).
VELTA Ti process allows manufacturing alloys directly during the reduction of titanium containing raw materials (solid solution of alloying element oxides in technical titanium dioxide).
These capabilities open the way for intermetallics production and production of a large number of high-quality alloys, especially those that are currently either difficult or even impossible to manufacture in industrial quantities due to engineering constraints or economic inexpediency.
Results and Discussion The shrinkage measured on sintered samples was 15 % for both materials.

Due to lack of appropriate supervision and maintenance about the Rocky desertification livestock project, creating a lot of engineering to become a short-lived project, the "bad deal" project, resulting in a waste of financial and human resources, ecological environment can’t achieve the desired effects.
Engineering content of the development of animal husbandry in accordance with the principles of livestock balance, reasonable arrangements for the stocking rate.
Through the rocky desertification control project and other related engineering, to restore vegetation coverage, at high altitudes, to living the environment, and bad natural recovery is very difficult vegetation degeneration of the lawn, should implement the enclosure, to restore vegetation.
After the implementation of the grass and associated works, the establishment of environmental and engineering stations, periodic supervision or inspection, regular maintenance and repair, education and persuasion on the destruction of the behavior of engineering and ecological environment related projects.
