The ability of microalgae to accumulate a large amount of lipids has made them a promising source of third-generation biofuels, focusing on raw materials that do not compete with human food sources.Interest in microalgae also lies in the range of molecules they can produce, including antioxidants, pigments, high molecular weight polyunsaturated fatty acids and vitamins.
It is often used in the fuel industry as an energy raw material.

In addition new materials like Carbon fiber and other composites with a very high stability have entered the prosthetic market [3].
For our prototype of the active driven knee prosthesis, we used the following components: - Mechanical build up: Combination of composite materials - Electric-drive: BLDC-Motor with a maximum power output of PMotor=200W - Kinematic solution: Bevel helical gearbox with mono axial knee axis - Energy source: Li-Ion-Battery - Sensor-System: Inertial Measurement Unit (IMU).
As the system should be easy to be produced, we decided to use a composite material for the housing.

Progress in the Theory Studies of CIECAM02 Li Jincheng1, 2, a, Liu Zhen3,b 1 College Of Light Industry Science and Engineering, Nanjing Forestry University, Nanjing, China; 2 School Of Printing Engineering , Hangzhou Dianzi University, Hangzhou ,China; 3 University of ShangHai For Science and Technology, College of Communication And Art Design alijincheng@hdu.edu.cn, blunaprint@163.com Keywords: CIECAM02; Uniform Color Space; the Reproduction Of Color Abstract.
Introduction For a long time, the visual characteristics of color has been one of the important issues in the field of color science, psychology and imaging technology, a large number of experimental and psychophysical experiments had be done to analyze the color information processes perceived by eyes, finally established the basic theory of colorimetry.
Color Management System (CMS) is an important technology which ensure accurate transmission between equipment, materials and workmanship.
Conclusion Although the CIE does not plan to launch an upgraded version based on the CIECAM02 color appearance model, researches for CIECAM02 color appearance model will continue for its excellent performance on prediction and broad application prospects in some field ,such as cross-media color reproduction, image science, imaging technology, medicine and so on.

On the Identifying of Influencing Factors of E-commerce based on the Quantile Regression HaiLiang Zhang 1, a, Ming Guo 2,b 1 Kunming University Of Science and Technology, College of Management & Economics, Yunnan Kunming, China 2 Kunming University Of Science and Technology, College of Management & Economics, Yunnan Kunming, China a zhhliang@yahoo.cn, bmingkwor@gmail.com Keywords: e-commerce, quantile regression, influencing factors.
In terms of theoretical studies on influencing factors of the development of e-commerce, Ma Qingguo (2000) declared that the electronic information market had a tremendous impact on the information flow, the people flow, the material flow and the capital flow and concluded that the information flow and the capital flow could be completely realized on the Internet; the people flow would be reduced; the material flow would be reorganized[2] .Sun Xudong (2003) believed that at the present stage, China was still in the initial development stage of the e-commerce and the third-party logistics market and logistics enterprises should provide satisfactory basic logistics services.
When there is no great breakthrough in the field of science and technology, the delivery and receiving time is relatively stable.
