"The problem goes beyond ordinary consumers being overcharged for a bottle of expensive wine from a famous winery with a great year listed on the label, that isn't the right vintage year," Jones said.Would all wines be tested and include a mention on the label to say the vintage had been proven by carbon-dating to be that listed?
Choosing the right physical technique to analyze paintings can make all the difference when it comes to ascertaining their authenticity.Now, a painting initially attributed as belonging to a series called 'Contraste de formes' by French Cubist painter Fernand Léger has definitely been identified as a forgery.Physicists have used carbon dating to confirm that an alleged Fernand Léger painting was definitely a fake.This is the first time it has been possible to identify a fake painting by relying on the anomalous behavior of the concentration of the radioactive form of carbon (14C) in the atmosphere after 1955 to date the canvas.A team of researchers in Australia, who think "vintage fraud" is widespread, have come up with a test that uses radioactive carbon isotopes left in the atmosphere by atomic bomb tests last century and a method used to date prehistoric objects to determine what year a wine comes from, or its vintage.
"Until the late 1940s, all carbon-14 in the Earth's biosphere was produced by the interaction between cosmic rays and nitrogen in the upper atmosphere," said Graham Jones of the University of Adelaide.
Reductions of 20 percent in paint use, 15 percent in energy consumption and 5 percent in production time – the Self Paint automated painting system offers significant advantages compared to manual ...
Researchers have reached striking results in their recently published paper Understanding the detection of fake view fraud in Video Content Portals.
They performed tests based on techniques including X-ray radiography and scanning electron microscope and energy dispersive X-Ray spectrometry.
Though they demonstrated that the fibers in the canvases differed and that different pigments were used in the two paintings, they did not arrive at conclusive evidence.
A spokesman for the three laboratories that recently analyzed samples of the relic is expected to make an announcement regarding the shroud's authenticity about a week from today, according to the scientist, the Rev. He took note of recent press reports in Britain that scientists at Oxford University had determined that the linen shroud was about 1,300 years too new to have been used to wrap the body of Jesus.
