Experimental study of the thermal insulation property of sedum linear roof module in real weather condition in Guangzhou, China Wang Zhangyuan1,a, Qiu Feng1, Yang Wansheng1,2 1School of Civil and Transportation Engineering, Guangdong University of Technology, Guangzhou 510006, China; 2State Key Laboratory of Subtropical Building Science, South China University of Technology, Guangzhou 510640, China azwang@gdut.edu.cn Keywords: green roof module; thermal insulation; comparative study Abstract.
Substrates used on roofs have primarily been based on natural soil mixes or recycled materials [3].
The aims of the tests are to obtain the thermal insulation properties of the four modules, which will provide solid experimental results for the use of the green modules in practical engineering projects and be especially useful for industrial purposes, as well as for design, city planning and research applications at green roof sites.
The testing was operated at the Outdoor Testing Field, Structural Laboratory, School of Civil and Transportation Engineering, Guangdong University of Technology, Guangzhou, China from 1st July to 5th September 2012.

From the sighure ,exports above(that is vertical, horizontal life cycle) build jointly a research framework of environment sectors and ecological problems to process industry-related resources, this study can be said PISEA key point, understand the cross-coupling of two lives cycle compound derived from the environment, making PISEA study more in-depth research, thorough, complete and systems.
No doubt, PISEA study involved longitudinal and transverse cross-coupling studies of life cycle, the basic theoretical foundation for the subject of environmental science, environmental science, but here is the process industrial development through the process of the link system and a set of relationships and social sciences, engineering sciences so integrated and applied PISEA, we can say that any support related disciplines study are effectiveness in PISEA.
In the relevant process, people's views or proposals will be subject to all relevant factors, such as the level of environmental engineering technology, solve real environmental problems underlying technical feasibility, environmental values’identity,and so on.

a badrinathan@hotmail.com, b karun@annauniv.edu Key words: End milling, Progressive feed rate, Tool wear, Design of Experiments (DOE), ANOVA Abstract - This study focuses on the effect of cutting parameters on the tool wear in a CNC end milling operation.
Krain et al. [6] in their experimental work evaluated the effect of feed rate, radial depth of cut, tool material and tool geometry on the tool life and tool wear during end milling of Inconel 718.
This instant acceleration creates high cutting forces and large material removal rate which in turn leads to the increased tool wear.

Knowledge Representation for �TRKB Based on Ontology To construct a network teaching resource knowledge base, the key process is to define all classes and their relationships, attributes and their relationships, the restrictions of attributes, and so on.
According to national Modern Distance Education Resources Construction Specifications, network teaching resources are supposed to include: media material, teaching material resource, item bank, paper material, software and network software, network course and subject website, scientific research resource, software resource, literature resource, Q and A, case and resource catalogue index, and so on.
The network teaching resource serves education directly, which is not only an accumulation of teaching materials and data, but also include other non-service behavior devoicing from teaching specialty.
Taken the network teaching resource knowledge base as an example, it refers to the notion of teaching course, software resource, literature material, Q and A and other resources.

Structural and Magnetic Properties of Cr- and Fe-doped CeO2 Nanoparticles Prepared by Sol-gel Method Shenghong Yang* and Yueli Zhang State Key Laboratory of Optoelectronic Materials and Technologies // School of Physics & Engineering, Sun Yat-sen University, Guangzhou 510275 China *stsyshh@mail.sysu.edu.cn Keywords: Cr- and Fe-doped CeO2, Sol-gel method, Magnetic property.
However, there is heated debate regarding the ferromagnetism of this material.
Cerium oxide (CeO2) is another promising material for DMS systems due to its electronic configuration, because cerium oxide can support deviations in-stoichiometry (CeO2-δ com 0 <δ< 0.5) while still maintaining afluorite-type structure [2].
Next, the xerogel was calcined at 800 °C for 2 h to eliminate organic materials and form a powder.

After the pioneering work by Iijima in 1991 [7], recent developments in the field of carbon nanostructured materials, such as Carbon Nanofibers (CNF) and Nanotubes (CNT), have generated tremendous interest particularly towards their application as catalyst supports.
This will involve investigation of two key challenges: firstly, obtaining good attachment of CNF to the microchannel walls and, secondly, controlled growth of CNF inside microchannels.
The purity of Ni target material was 99.99%, and at least 99.95% for adhesion metals.
