BEIJING Matt Duchene Canada Jersey , Nov. 6 (Xinhua) -- With an orange alert for air pollution in place for the last two days, Beijing has adopted a raft of emergency measures to meet the smog challenge head-on.


On Sunday, the city's housing and urban-rural development authorities investigated over 2,000 construction sites and 62 sites that did not meet the standards required to improve their pollution controls.


The city's transport authorities punished 3,078 cases of illegal operation of trucks carrying construction materials, and 1,556 high-emission vehicles planning to enter Beijing were convinced to return back.


Beijing Municipal Environmental Monitoring Center said the capital will see pollution peak on Monday Martin St. Louis Canada Jersey , and air quality is expected to improve from Tuesday night under the influence of a cold front.


Last week, the Ministry of Environmental Protection (MEP) forecast that Beijing, Tianjin, Hebei and their neighboring regions would see slight to severe air pollution from Nov. 4 to 8.


An orange alert, the second highest level for air pollution, was enacted on Nov. 4 simultaneously in Beijing and Tianjin, and some cities in Hebei Mark Messier Canada Jersey , Shanxi, Shandong and Henan provinces.


Under the orange alert, the cities are encouraged to take various measures to curb pollution, such as restricting the use of vehicles, increasing pollution controls at construction sites, removing from roads trucks transporting construction materials, and reducing or stopping production at some companies.


Air quality usually worsens in late autumn and winter in northern China due in part to less wind and increased emissions from heating sources.


Liaoning Province in northeast China started heating supply on Nov. 1. The provincial capital Shenyang strengthened supervision of heating supply companies and asked them to avoid operating boilers in peak hours.


The city has also added 1 Mario Lemieux Canada Jersey ,350 new clean energy buses to its roads this winter.


China has channeled more work into improving air quality in the Beijing-Tianjin-Hebei area by measures such as replacing dirtier coal use and penalizing polluters.


Inspection teams have been dispatched to cities identified as sources of pollution and companies in breach of emission rules, according to the MEP.


In 2017, Beijing plans to decrease coal use by helping residents at 700 villages adopt clean energy, removing 300,000 vehicles from roads, and shutting down 500 factories.


In August, China published an action plan about air pollution governance of Beijing Marc-Edouard Vlasic Canada Jersey , Tianjin, Hebei and neighboring regions in autumn and winter from 2017 to 2018.


According to the plan, from October 2017 to March 2018, the average PM2.5 density in the concerning areas is expected to drop by over 15 percent year-on-year.


According to the Beijing Municipal Environmental Protection Bureau, the capital city's average PM2.5 density dropped to 60 micrograms per cubic meter in the first three quarters of this year, down 3.2 percent compared with the same period last year, and down 34.8 percent compared with 2013.



  This handout 3D artistic view made by the ScanPyramids mission and released on November 2 Jonathan Toews Canada Jersey , 2017 by the Nature Publishing Group shows a hidden internal structure in Khufu's Pyramid, the largest pyramid in Giza. Scientists have found, but not yet examined, a mysterious, Boeing-sized "void" in the Great Pyramid of Egypt — a fourth cavity besides the already-known king and queen's "chambers" and Grand Gallery, they announced on November 2, 2017.

Scientists using an imaging method based on cosmic rays have detected a large and enigmatic internal structure in the last of the Seven Wonders of the Ancient World still standing John Tavares Canada Jersey , the massive Great Pyramid of Giza on the outskirts of Cairo.


Researchers announced the discovery on Thursday but said they did not know the purpose, contents or precise dimensions of what they are calling a "void" or "cavity" inside the pyramid, built as a monumental tomb around 2560 BC.

Cosmic-ray imaging finds hidden structure in Egypt's Great Pyramid

To peer inside the pyramid, the scientists used an imaging technique called muon tomography that tracks particles that bombard Earth at close to the speed of light and penetrate deeply into solid objects.


They said the newly discovered internal structure was at least 100 feet (30 meters) long, and located above a hallway measuring about 155 feet long (47 meters) called the Grand Gallery, one of a series of passageways and chambers inside the immense pyramid. The researchers said it constitutes the first major inner structure found in the Great Pyramid since the 19th century.


"What we are sure about is that this big void is there, that it is impressive Joe Thornton Canada Jersey , that it was not expected by, as far as I know, any kind of theory," said Mehdi Tayoubi, president and co-founder of the HIP Institute in France, one of the leaders of the study published in the journal Nature.


"We open the question to Egyptologists and archaeologists: what could it be?" added Hany Helal of Cairo University.


The Great Pyramid, looming alongside other large pyramids Jeff Carter Canada Jersey , is a towering achievement, remarkable for its simple beauty and colossal grandeur. The emblem of one of the great civilizations of antiquity, it soars to a height of 479 feet (146 meters), the tallest structure built by humankind until the Eiffel Tower in Paris in 1889, and boasts a base measuring 754 feet (230 meters).


It was constructed during the reign of the Pharaoh Khufu, or Cheops.


The findings come from a project called Scan Pyramids that relies on non-invasive scanning methods to probe the internal structure of the pyramids of ancient Egypt's glorious Old Kingdom period and understand how they were built.
