The arch of the Hutong Yangtze River Bridge's channel bridge was connected on Sunday Cheap Nike Air Max 1 , a breakthrough in the construction of the bridge linking Shanghai and Nantong City in Jiangxi Province.

The channel bridge's span, on the north side of the Hutong Yangtze River Bridge, is 336 meters long and weighs 32,400 tons. The main bridge body of this section will be built this year.
Construction on the 11 Cheap Nike Air Max 90 ,072-meter-long Hutong Yangtze River Bridge started in March 2014. As a joint project of the Shanghai-Nantong railway, the bridge has a design that allows dual-use, with rails on the lower layer and a highway on the top.
The main bridge is the world's longest cable-stayed bridge, spanning 1,092 meters on the south side Cheap Nike Air Max , and 336 meters on the north, crossing Tiansheng port's special channel.
"The bridge will become the third access way to cross the Yangtze River," said an official from the construction side. "The travel time from Shanghai to Nantong will be reduced to about one hour."
WASHINGTON, Aug. 3 (Xinhua) -- Scientists using the world's smallest neutrino detector reported Thursday that they have observed the "elusive interactions" of the ghostly particles with the nucleus of an atom for the first time.
The research, performed at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) and published in the U.S. journal Science Cheap Air Max 1 , confirmed a neutrino interaction process predicted by theorists 43 years ago, but never seen.
"The one-of-a-kind particle physics experiment at Oak Ridge National Laboratory was the first to measure coherent scattering of low-energy neutrinos off nuclei," ORNL physicist Jason Newby, technical coordinator for the so-called COHERENT experiment, said in a statement.
Neutrinos Cheap Air Max 95 , often referred to as "ghost particles," are a challenge to study because their interactions with matter are so rare.
Particularly elusive has been what's known as coherent elastic neutrino-nucleus scattering, which occurs when a neutrino bumps off the nucleus of an atom.
In the new study, the researchers designed the detector that is a cesium iodide scintillator crystal doped with sodium to increase the prominence of light signals from neutrino interactions.
They installed the detector at ORNL's Spallation Neutron Source (SNS), which produces neutrons for scientific research and also generates a high flux of neutrinos as a byproduct.
"Placing the detector at SNS Cheap Air Max 90 , a mere 65 feet (20 meters) from the neutrino source, vastly improved the chances of interactions," the study said.
"That signal is as tough to spot as a bowling ball's tiny recoil after a ping-pong ball hits it," it said.
Meanwhile, the new design allowed the researchers to decrease the detector's weight to just 14.5 kilograms Cheap Air Max , enough for a researcher to carry.
In comparison, the world's most famous neutrino observatories are equipped with thousands of tons of detector material.
The COHERENT experiment involves more than 80 researchers from 19 institutions and four nations and has been in operation for more than one year at ORNL.
Through measuring coherent elastic neutrino-nucleus scattering, physicists hope to better understand the properties of the mysterious particle.
"Neutrinos are one of the most mysterious particles," said physicist Juan Collar of the University of Chicago who led the design of the detector. "We ignore many things about them. We know they have mass, but we don't know exactly how much."

BERLIN Cheap Nike Air Max 1 Shoes , Aug. 15 (Xinhua) -- German doctor Hartmut Hopp has been sentenced to five years in prison on Tuesday for his involvement in abuse at the Chilean Nazi pedophile commune of "Colonia Dignidad."
A previous sentence was thus upheld by the Krefeld court although the ruling is not final, and Hopp's lawyers have announced an appeal.
Colonia Dignidad was an enclave of German expatriates and Nazi fugitives which achieved international notoriety after reports of sexual abuse of children and minors, the rigid indoctrination of members, and slavery-like practices and torture over the course of three decades.
The physician Hopp acted as the right-hand man of Paul Schaefer, the former Wehrmacht-soldier and convicted pedophile who founded Colonia Dignidad in 1961.
Hopp was already convicted in Chile back in 2011 for crimes including complicity in the sexual abuse of 16 minors. However Cheap Nike Air Max 95 Shoes , he managed to flee to Germany before the final court ruling was imposed.
