Introduction Because of the soft hand feeling, cozy wearing, easy dyeing and environmental benign, cotton is the most useful clothing material currently.
This project uses the hexamethylene diisocyanate and polyethyleneglycol as raw materials to synthesize the waterborne polyurethane [1] which was then applied as binders during the nano-TiO2 finishing process.

In2003, Qu Juan and Li Huai discussed ladder-type tooth chain connector from the angle of materials and process measures.
when the cambered surface tooth structure of the chain connector processes, not only considered certain cambered surface tooth profile is guaranteed, but also the batch processing, therefore in the chain connector jig design, the jig clamps the rough material of chain connector both to have the deflection angle-causing the chain connector tooth department to become the cambered surface, and to design locating jig like flower petal shape distribution-may process six half-ring components at the same time disputably, thus improve the processing efficiency greatly.

Performance Evaluation of the Horizontal Subsurface Flow Constructed Wetland with Ipomoea aquaticaplantfor Rural Domestic Wastewater Treatment Ahmed Mohammed Osman1,2,a, Lu- Xiwu*1,b 1Environmental science and Engineering Department, Southeast University, Nanjing 210096, China 2Civil Engineering Department, Karary University, Khartoum 12304, Sudan aEmail:ahmedosm77@yahoo.com; *bEmail: luxiwu@seu.edu.cn Keywords:Ipomoea aquatica; Horizontal subsurface flow constructed wetland; Hydraulic loading rate; Nutrients.
The constructed wetlands (CWs)  are widely used worldwide to accomplish secondary and tertiary treatment of the domestic, municipal, and industrial wastewaters [2].The CWs offers an attractive option to wastewater treatment with efficient and less energy intensive, low operation costs and maintenance requirements, and they are more aesthetically pleasing compared with conventional wastewater treatment systems [3-6].Many of contaminants such as organic material, nutrient, total coliforms, and heavy metals can be removed from the wastewater by CWs via sedimentation, coagulation, adsorption, filtration, plant uptake, and microbial transformation[7-9].Some factors have effect on the CWs performance such as hydraulic loading rate (HLR), constructed wetland configuration and vegetation type[10].The HSFCWis suitable treatment systemused for cold climates becausewastewater treatment occurs below the surface [11].It is the most common CW systems used in worldwide especially in Europe [12].
In this study, the HSFCW planted with Ipomoea aquatica(Chinese spinach)was applied as a tertiary treatment to evaluate their performance on the organic material and nutrients removal efficiency.The integrated system schematic diagram is shown in Fig.1.
Material and methods Constructed wetland setup and experimental procedures The experimental system was made up of the HSFCW system as a rectangular basin with dimensions of 2.3 m (L) ×0.6m (W) × 0. 4m (D) and thebed slope is 0.5%.

WEEE Management in Chongqing, China: Status and Strategies Jiaxiang Li1,a, Chuan Huang1, Yin Zhu1 and Shan Huang1 1Department of Resource and Environmental Science, Chongqing University, Chongqing, 400030, China ajxlee_0109@yahoo.com Keywords: Waste electrical and electronic equipment (WEEE), Waste management, Extended producer responsibility (EPR), Chongqing Abstract.
The implementation of EPR should achieve several goals, reported by Langrova as follows[10]: (i) waste prevention and reduction; (ii) product reuse; (iii) increased use of recycled materials in production; (iv) reduced natural resource consumption; (v) internalization of environmental costs into product prices; (v) energy recovery when incineration is considered appropriate.

Geo-stress Measurement and Its Application in the Yangchangwan Coal Mine Xiaoyu Zhang1, Fengming Liu2, Gang Chen1 (1.Heilongjiang Institute of Science & Technology, Recourses and Environmental Engineering Institute, Heilongjiang, Harbin, 150027; 2.China university of mining and technology (Beijing), Faculty of Resources & Safety Engineering, Beijing, 100083) Keywords: Geo-stress measurement; Geo-stress; hollow inclusion stress method Abstract:The initial stress of rock is a basic parameter, which can be used for surrounding rock stability analysis, exploitation and support design.
It assumes that the rock in a small range of measuring point is a homogeneous, continuous and isotropic linear elastic material.
(3) It explains the question why it is difficult to support -1000 level open cut-eye, whereas crossheading is easy to support, it also provides a basis for roadway support and the selection of support materials
