Decks, Patios and Porches
Bettendorf Home Repair has extensive experience with deck construction. All of our decks are built to surpass code requirements with 6”x6” support posts and 2”x10” joists for strength. We offer Azek brand decking and beautiful Heartland brand vinyl handrails. We also construct decks out of treated lumber and cedar. We have built porches for older homes (1900’s) that were constructed to keep the original look of the home in mind and we have built modern decks that wrap around swimming pools and are strong enough to support a hot tub.
Burned Vesuvius Scrolls Read for First Time "It’s the first time a technology achieves seahawks kam chancellor youth jersey such a result," Vito Mocella, a physicist from the National Research Council’s Institute for Microelectronics and Microsystems (CNR IMM) in Naples, told Discovery News. miles burris youth jersey "Until now, imaging techniques have been unable to view the carbon based ink of these papyri, even when they could penetrate the different layers of their spiral structure." Photos: Peering Inside an Ancient Papyrus The authentic steelers markus wheaton mens jersey scrolls used by Mocella’s team were excavated 260 years ago from the Villa of the Papyri in Herculaneum, a authentic percy harvin womens jersey magnificent seafront estate perhaps owned by Lucius Calpurnius buccaneers clinton mcdonald youth jersey Piso, Julius Caesar’s father in law. The villa housed one of the finest libraries of antiquity. Consisting mainly of Epicurean philosophical texts, the scrolls were carefully stored in shelves covering the walls. During the devastating eruption of Mount Vesuvius, the scrolls, as well as the Herculaneum citizens, were burned by a furnace like blast of hot gas. Paradoxically preserved forever (Herculaneum’s seaside air would have destroyed them) the scrolls are now stored at the National Library of Naples. They make up the only library known to have survived the ancient world. The carbonized scrolls are thought to hold Aristotle’s lost 30 dialogues, philosophical work by Epicurus, erotic poems by Philodemus, Virgilius’s lost eclogue, scientific work by Archimedes and lesbian poetry by Sappho. ‘Pompeii:’ 10 Strange Facts About the Roman Empire Out of the 1,785 scrolls discovered during the 18th century excavation, only 585 had been completely unrolled using a 18th century mechanical method, while 209 have been partly unrolled. About 400 have never been unrolled and 450 are so difficult to read that their text authentic olivier vernon mens jersey remains unknown. "These carbonized papyri are extremely fragile and are inevitably damaged or destroyed in the process of trying to open them to read their contents," Mocella and colleagues wrote in the journal Nature Communications. Any attempt using non invasive procedures to read the scroll, including multi spectral technology, have proven ineffective. Photos: Apollo Mosaic Found in Rome Tunnel The ink used to write the texts was the main barrier. "Multi spectral imaging has improved the readability of these texts considerably, but unfortunately it is not applicable to texts that remain rolled up," Mocella said. "In antiquity, papyri were written using a black carbon based ink obtained from smoke residues, the density of which is almost the same as that of the carbonized papyrus," the researchers authentic 49ers brandon lloyd youth jersey wrote. Until now, therefore, it has authentic lawrence timmons mens jersey appeared impossible to distinguish ink from papyrus inside a scroll using conventional X ray techniques. To overcome the problem, Mocella and colleagues turned to X ray phase contrast tomography (XPCT), a 3 D X ray imaging technique most commonly used in authentic dolphins knowshon moreno womens jersey medicine.
