Unlike repaving a street in your neighborhood, Daytona's a banked surface designed to allow cars to reach speeds as high as 210 mph. This means crews have to carefully mill and grade each turn for the appropriate angle.
Once the appropriate angle is set, a large dump truck carrying asphalt transfers the crushed rock to a small buggy, which then transports the asphalt to the hydraulic crane. So far this process isn't much different from how it's normally done, but the next step involves a lot of engineering.
The asphalt is transferred from the crane to an ABG Titan 525 Paver, which lays it along the surface of the track. In order to achieve the angle the paver's suspended from the track at a 31-degree angle by a Caterpillar D9 Bulldozer at the top of the track. This is followed by a Hamm DV-8 Double Steel Drum Roller, also suspended by a bulldozer. The Drum Roller uses its immense 40,000 pounds of weight to crush the material into a smooth surface. This is repeated numerous times until the surface is dense enough to support racing.
i was trying to explain jeremy bentham’s panopticon to my 5 year-old nephew this weekend and he was like, “geesh uncle ray, i already know all about that because of lost.” and then i was like, “look here half-pint, just cuz the producers of that television programme copy-pasted philosophers’ names for their characters’ names to spice up the mystery (despite the fact that the relationship is tenuous at best) this does not mean that you know the first thing about jeremy bentham or his panopticon.” and then my 5 year-old nephew turned on the waterworks and his mom made her way over to us and gave me disparaging looks.
The "cheating" was that students got their hands on the textbook publisher's "testbank" of questions. Many publishers have a testbank that professors can use as sample test questions. But watching Quinn's video, it became clear that in accusing his students of "cheating" he was really admitting that he wasn't actually writing his own tests, but merely pulling questions from a testbank. That struck me as odd -- and I wasn't really sure that what the students did should count as cheating. Taking "sample tests" is a very good way to learn material, and going through a testbank is a good way to practice "sample" questions. It seemed like the bigger issue wasn't what the students did... but what the professor did.
In looking around, it looks like a lot of the students agree. They're saying that the real issue is that Prof. Quinn simply copied questions from the publisher, rather than actually recreating his own test, and noting that this seems like a massive double standard. The professor is allowed to just copy questions from others for his tests? In fact, some of the students have put together a video pointing out that, at the beginning of the year, Prof. Quinn claimed that he had written the test questions himself.
All you will need to be prepared in any emergency is an Altoids or equivalent tin, some tiny bottles (the smallest one is from a miniature Tabasco sauce bottle), a tiny ziploc bag, a folding paper cup (about the easiest origami there is), and the stopper cannibalized from a dollar store water pistol. Oh, and of course gin (I favour Plymouth) and vermouth (Noilly Prat).
Marine biologist Silvia Maciá was boating on the north coast of Jamaica in the summer of 2001 when she noticed something soar out of the sea. At first she thought it was a member of the flying fish family—a group of marine fish that escape predators by breaking the water's surface at great speed and gliding through the air on unusually large pectoral fins. But after tracing the creature's graceful arc for a few seconds, Maciá realized this was no fish. It was a squid—and it was flying.
With her husband and fellow biologist Michael Robinson, Maciá identified the airborne cephalopod as a Caribbean reef squid (Sepioteuthis sepioidea)—a lithe, torpedo-shaped critter with long, undulating fins. They think the squid was startled by the noise of the boat's outboard engine and estimated that the 20-centimeter-long mollusk reached a height of two meters above the water and flew a total distance of 10 meters—50 times its body length. What's more, the squid extended its fins and flared its tentacles in a radial pattern while airborne, as though guiding its flight.
"It was doing this weird thing with its arms where it had them spread out almost in a circle," recalls Maciá, who teaches at Barry University in Florida. "It had its fins kind of flared out as much as it could—it really looked liked it was flying. It hadn't accidentally flopped out of the water; it was maintaining its posture in a certain way. It was doing something active."
New features in Version 2.0 included the ability to overlap application windows and improved memory use. Also new: Dynamic Data Exchange (DDE), which allowed Windows applications to automatically share and update data. For example, DDE allowed information in an Excel spreadsheet to be automatically updated when data in another Excel spreadsheet was changed.
The Scottish Tartans Authority has decreed that refusing to put on underwear beneath a kilt is "childish and unhygienic".
It also warned that "going commando" flies in the face of decency.
Tartans Authority director Brian Wilton said kilt wearers should have the "common sense" to realise they should wear underwear beneath their country's national dress.
"An argument can be made for and against every song mentioned," he said before adding "That's All Right Mama" is a better fit than all of the other tunes.
This song came out in September 1946 as a rockabilly piece with a blues melody line over top.
"It's sung with power, may contain the first guitar solo break, and, as a remake, became one of Elvis' first singles," Burns said.
The origin of the term "rock 'n' roll" is straightforward, he believes.
"It started as a nautical phrase meaning the movement of the boat up and down and back and forth," Burns said. "Sometime in the late 1800s to early 1900s, gospel and jubilee music co-opted the term and used it to mean being rocked and rolled in the arms of the Lord. In fact, the first recorded use of the term in a song was 'Camp Meeting Jubilee' in 1916."
Semmelweis didn't just have the disregard of his contemporaries, he had their flat-out scorn. Maybe it was because he didn't get around to explaining himself on paper right away, so no one understood what hand-washing had to do with keeping people alive. Some doctors were actually insulted that he was accusing Viennese medical students being dirty enough to kill people.
Within 14 years of his groundbreaking discovery, Semmelweis just stopped giving a [redacted -- ed.]. He got drunk all the time and called all his detractors "ignoramuses" and "murderers." He started chilling with prostitutes and lashing out at family. That last part proved to be a bad move, because in 1865 they had him committed to an insane asylum, where he was promptly beat up and stuck in a dark cellar.
He died two weeks later. It took another 20 years and Louis Pasteur's germ theory for the rest of the world to come around to the concept of washing your hands to keep from getting sick.
A*STAR’s IMRE and 10 EU research organisations are working together to build what is essentially a single molecule processor chip. As a comparison, a thousand of such molecular chips could fit into one of today’s microchips, the core device that determines computational speed. The ambitious project, termed Atomic Scale and Single Molecule Logic Gate Technologies (ATMOL), will establish a new process for making a complete molecular chip. This means that computing power can be increased significantly but take up only a small fraction of the space that is required by today’s standards.
The fabrication process involves the use of three unique ultra high vacuum (UHV) atomic scale interconnection machines which build the chip atom-by-atom. These machines physically move atoms into place one at a time at cryogenic temperatures. One of these machines is located in A*STAR’s IMRE.
