Aluminum Recycling - Challenges and Opportunities Musbah Mahfoud1,a and Daryoush Emadi2,b 1Department of Mechanical Engineering, College of the North Atlantic-Qatar, Doha, Qatar 2CANMET Materials Technology Laboratory, Ottawa, Ontario, Canada a musbah.mahfoud@cna-qatar.edu.qa, bdemadi@NRCan.gc.ca KEYWORDS: Aluminum, Recycling, Impurities, Challenges Abstract.
These impurities have been a major concern for most aluminum cast houses for the last 20 years and have necessitated the development of advanced recycling technologies and new treatments for molten aluminum.
In addition, the development of advanced scrap sorting technologies would allow recycling of aluminum scrap to be done more efficiently and make alloys with application-tailored specifications.
However, to make meaningful advances toward some long-term goals such as sustainability, zero waste, and net positive energy impact, the industry will also need advanced, energy efficient technologies and new manufacturing concepts.
The industry should also explore with advanced methods of automation and optimization of pre-sorting, shredding and separation technologies, and make them broadly available.

Optimization of Development Mode During the Later Steam Huff and Puff in Heavy Oilfield Zhao Yang, Han Gao and Dongyang Zhang Petroleum Engineering Institute, Northeast Petroleum University, Daqing Heilongjiang 163318, China Keywords: Horizontal Wells;Steam Huff And Puff; Steam Drive;Numerical Simulation Abstract.
When the injection rate is determined, the longer the horizontal section is, the lower the gas-oil ratio is, which decreases the advancing speed of steam.

In the public crisis event occurrence, development and variation in the process, the network media and the internet groups active or randomly to the network as a platform, through the news, forum transmitted by means of information collection, analysis and exchange, forming a network of public opinion events or variation based on the characteristics of distributed, multiple etc. network public opinion has formed spontaneously storm, content complex of magnanimity and argument.
Network public opinion constantly, both published in well-known portal sites, famous newspaper website, also have somewhere deep in other forums, BBS and so on.

The final objective of this study, carried out at the Advanced Forming Research Centre (AFRC, University of Strathclyde, UK), is to obtain material data to calibrate and validate a model capable of estimating the behaviour and grain size evolution of titanium alloys at superplastic conditions.
The current demand for reduced fuel consumption in combination with high quality manufacturing standards, is driving the aerospace engineering sector to develop new materials that can both lead to significant weight savings and withstand challenging environments, while remaining easy to manufacture.
