LJUBLJANA Nike Air Max Thea Pas Cher , Sept. 4 (Xinhua) -- The 12th Bled Strategic Forum (BSF) was held at Lake Bled in Slovenia on Monday to gather common international solutions to challenges posed by the changing world, including climate change and security threats.


The Forum (BSF) attracted 1,000 officials, executives and academics from some 70 countries all over the world to seek solutions to the challenges of the "new reality", according to the Slovenian Press Agency.


The host Nike Air Max Tavas Pas Cher , Slovenian Foreign Minister Karl Erjavec, stressed in his address that "we are facing new international actors" and "still struggle to address climate change and its negative global impact".


Slovenian Prime Minister Miro Cerar and President Borut Pahor made their speeches at the forum opening ceremony, calling for joint efforts to deal with new challenges.


The event will continue on Tuesday for its second and last day featuring the Business BSF conference and several panels, including on nuclear governance, challenges in tourism Nike Air Max 95 Pas Cher , the role of the EU in the changed world, the Western Balkans and digital diplomacy.

WASHINGTON Nike Air Max 2018 Pas Cher , Aug. 24 (Xinhua) -- Chinese scientists said Thursday they have developed a super steel that has a high level of both strength and ductility, a breakthrough that may have a wide variety of industrial applications.


Furthermore, its material cost is just one-fifth of that of the steel used in the current aerospace and defence applications, they reported in the U.S. journal Science.


Strength and ductility are desirable properties of metallic materials for wide-ranging applications, but increasing strength often leads to the decrease in ductility Nike Air Max 2019 Pas Cher , which is known as the strength-ductility trade-off.


A Hong Kong-Beijing-Taiwan mechanical engineering team led by Huang Mingxin from the University of Hong Kong adopted a new manufacturing technique called deformed and partitioned (D&P) to addressed the problem.


"Steels have been the most widely used metallic materials in the history of mankind and can be produced with much higher efficiency than any other metallic materials," the team said in a statement.


"Therefore developing a strong and ductile breakthrough steel has been a long quest since the beginning of Iron Age in mankind history."


The team explained that it is very difficult to further improve the ductility of metallic materials when their yield strength is beyond two Gigapascal (GPa).


Now, they made "a successful attempt in realizing the above dream" as the newly developed method yields a "breakthrough steel" that has the "unprecedented" yield strength of 2.2 GPa and uniform elongation of 16 percent.


"The developed D&P steel demonstrated the best combination of yield strength and uniform elongation among all existing high-strength metallic materials," the researchers said.


"In particular, the uniform elongation of the developed D&P steel is much higher than that of metallic materials with yield strength beyond 2.0 GPa."


According to the team Nike Air Max 270 Pas Cher , the "breakthrough steel" belongs to the system of so-called medium manganese steel that contains 10 percent manganese, 0.47 percent carbon, 2.0 percent aluminium and 0.7 percent vanadium.


"No expensive alloying elements have been used exhaustively but just some common alloying compositions that can be widely seen in the commercialized steels," they said.


Another advantage is that this steel can be developed using conventional industrial processing routes, including warm rolling , cold rolling and annealing.


"This is different from the development of other metallic materials where the fabrication processes involve complex routes and special equipment, which are difficult to scale-up," said the team.


"Therefore, it is expected that the present breakthrough steel has a great potential for industrial mass production."


The research outcome was a collective contribution from scientists at the University of Hong Kong, University of Science and Technology Beijing Nouvelle Nike Air Max Pas Cher , City University of Hong Kong, and a university in Taiwan.


RAMALLAH, Sept. 17 (Xinhua) -- Palestinian President MahmoudAbbas said Sunday he was satisfied with Islamic Hamas movement'searlier decision to take practical steps towards achieving internalreconciliation.


Abbas, who arrived in New York for joining the UN annual GeneralAssembly meetings, said in an official statement that he wassatisfied with Hamas' declaration in Cairo to reconcile.


Earlier on Sunday Chaussures Nike Air Max Pas Cher , Hamas leaders, who have been holding talkswith senior Egyptian security intelligence officials, said in anofficial statement that they were ready to make reconciliation withAbbas Fatah Party.


Hamas announced earlier that it had dissolved an administrativecommittee to manage the daily affairs in Gaza. The forming of thecommittee has outraged Abbas, who insisted that it should beresolved in order to resume the dialogue with Hamas.


Hamas, which has been ruling the Gaza Strip since seizingcontrol of it in 2007 Nike Air Max Pas Cher , has expressed readiness to receive thePalestinian consensus government in Gaza and to allow it to workproperly.


Leaders of the Hamas-run administrative committee in Gaza alsosaid that they were ready to fully cooperate with the consensusgovernment and to hand over the Gaza Strip affairs.
