Examples include freight rates for China’s iron and steel raw materials and Japan’s grain in 2007.
In 2007, the price of shipping raw materials from Brazil and Australia for China’s iron and steel enterprises more than doubled in a single year compared with 2006.
The choices of ship routines, ship configuration, countries of raw materials and port network layout for import and export cargo are all directly related to the allocation of world resources, trade product cost and national economic security.
The development of marine engineering technology allows human to be more and more involved in the marine space [5].

As a kind of cheap and environment friendly photocatalyst, the TiO2 particles (especially its nanoparticles) have been considered as potential materials in some fields, such as sewage treatment, air purification and solar cells [1-3].
In order to improve the catalytic efficiency, stability and the light absorption range of the nano-TiO2 materials, researchers have recently used many methods (such as doping, grafting light absorption unit, impregnating, and so on) to prepare the new nano-TiO2 materials [4-8].
Grey system theory has been used widely in economic, management and engineering techniques, since it was established by prof.

Introduction World Health Organization key facts [1] suggest that about 1.24 million people die each year as a result of road traffic crashes.
The paper is organized as follows: second section presents material and methodology, third section presents models, the results are presented in the fourth section.
Materials and Methodology In this study, secondary data of the Statistical Office of the Slovak Republic, Ministry of Interior Affairs of the Slovak and the Slovak Road Administration were used.
An interesting point is that damages to property have been dramatically decreased, as well as traffic accidents and accidents with material damage after the introduction of 50 km per hour speed limit in villages in Slovak Republic.

Introduction This work was conducted as part of a European Union project entitled ARTIMA (Aircraft Reliability Through Intelligent Materials Application).
The damage detection work here is conducted upon a flat aluminium plate with two piezoceramic transducers mounted on thin layers of the soft viscoelastic material ISD112.
The key feature of this specimen, however, was that these two transducers were both mounted on the plate using a thin layer of the viscoelastic material ISD112.

Wheel characteristics are mainly decided by the kind of grits, grit mesh size, bonding material, hardness, porosity and so on.
In this paper, the mechanism of improvement in surface finish in the HS grinding is investigated by using a three dimensional computer aided design model (3D-CAD model) and a concept of virtual grinding trace as a result of interference of grit trajectory and work material.

Introduction In the thermal plasmas spray, plasma gas temperatures can be acquired about 18,000K, thereby enabling melting any materials injected into the plasma jet, including ceramic materials with high melting point.
So, the plasma temperature field is the key process parameters, which is depended on plasma gas compositions, gas flow rates, electric input power etc [1, 2].

Moreover, adhesion of the work material on the tool plays an important role in determining the machined surface quality at higher cutting speeds.
In the cutting zone, the work piece material showed less viscous caused by the high temperature and generally sticks on the hills of feed marks.
Moreover, the chip-tool contact is mostly plastic at higher cutting velocity and feed rate especially for cutting hard to cut materials, so the cutting fluid applied conventionally cannot reduce the chip-tool interface temperature effectively because the fluid can hardly penetrate into the interface [12].

Preparation and Characterization of Fe3O4-Pt/C Electro-catalysts for Zinc-air Battery Cathodes ZHAO Hong1, a, WANG Haili2,b LIANG LiJun 3,c XU Hongfeng4 and FU Jie5 1-5 College of environment & chemical engineering, Dalian Jiaotong University, Dalian, China, azhaohong@djtu.edu.cn, byekong2005@126.com, clianglijun.hao@163.com Keywords: Fe3O4, zinc-air battery, oxygen reduction reaction, carbon-coating Abstract.
Therefore, some common requirements on oxygen electrode catalyst materials are postulated a good catalytic activity of oxygen reduction; resistance to electrolyte corrosion; resistance to oxidation/reduction atmosphere corrosion; large conductivity; large specific surface area [3].
Oxygen is a paramagnetic material; therefore the paramagnetism of Fe3O4 probably causes the enrichment of oxygen and enhances the ORR activity of the electro-catalyst.
In an alkali medium, whether O2 is directly reduced to water via a four-electron process or to HO2- via an two-electron process is set by the composition of electrode materials [12].
Pt plays a crucial key in the reduction process, while Fe3O4 enhances direct a four-electron process by enriching O2 concentration.
