AMD Q1 2013 earnings: softer $146 million net loss on $1.09 billion revenue

AMD Q1 2013 earnings softer $146 million net loss on $109 billion revenue

Just two days after the earnings report of its storied rival, AMD has followed suit with a Q1 2013 balance sheet of its own. The company reported a net loss for the quarter of $146 million, which stings, but isn't quite so painful as the $473 million loss that it took just one quarter earlier. Meanwhile, AMD's revenue of $1.09 billion is more or less flat from the previous quarter, but has fallen by $500 million since Q1 of the previous year. The announcement was enough to make investors wince, as AMD's stock price is now declining in after-hours trading. As for a silver lining, AMD emphasized that its gear will power the upcoming PS4. If Microsoft were to make a similar decision, then perhaps AMD could turn its financial frown upside-down.

NASA Engineers Developing New Version of the Apollo Era F-1 Rocket Engine

Engineers working on the heavy lift Space Launch System, envisioned to carry astronauts beyond low Earth orbit, are pursuing a back-to-the-future approach by examining the engines that sent astronauts to the moon more than 40 years ago.

Reverse engineering the F-1 engine

According to a story in Ars Technica, engineers at NASA's Marshall Spaceflight Center are reverse engineering the F-1 engine, the most powerful rocket engine ever used, that powered the first stage of the Saturn V moon rocket. NASA has a number of unused F-1s in storage since the last three Apollo moon landings were cancelled during the early 1970s. NASA engineers have an ancient F1 engine in a workshop and have started to take it apart, to understand its design, and to ascertain how a version of it could be used in the Space Launch System.

F-1 engine design

The original F-1 engines, according to NASA, were developed in the 1960s and burned liquid oxygen and kerosene. They were 19 feet high and 12 feet 4 inches in width. Each engine could exert 1.5 million pounds of thrust at sea level. The operating temperature in the thrust chamber was 5,970 degrees Fahrenheit. Five of these engines were used in the first stage of the Saturn V.

Making modern documents of the F-1

One of the first tasks of the engineering team examining the F1 was to create modern computer-aided design documents of the engines, according to Ars Technica. The original design documents still exist, but are somewhat incomplete, having been created under deadline pressure during the space race. Using modern digital scanning devices, the engineers meticulously examined the F-1's engine's exterior, then its interior, sometimes having to literally create the tools needed to take the engine apart safely. The resulting CAD document can be used to manufacture parts of the F-1 using modern techniques.

Test firing parts of the F-1

Next, according to a story in Space.com. the gas generator, which is used to drive the turbo pump for the F-1, was test-fired for the first time in decades. Using modern instruments, data that was unavailable in the 1960s was gathered for the first time.

Building a new F-1

The ultimate goal of the F-1 forensics examination is to create a new engine, the F-1B, which can be used as part of a strap-on booster for the Space Launch System called the Pyrios, according to Ars Technica. The Pyrios would have two F-1B engines each capable of generating 1.8 million pounds of thrust. The F-1B would be manufactured using 3D printing techniques and would be a vastly simplified from the F-1, using 40 manufactured elements as opposed to 5,600. The manufacturing process will reduce welds and joins (all done by hand for the original F-1) reducing the cost of the F-1B. The Pyrios strap-on booster is competing against a solid rocket booster similar to the ones that helped to launch the Space Shuttle into low Earth orbit.

Additional imaging gives better view and reduces complications in patients needing gastric tubes

Additional imaging gives better view and reduces complications in patients needing gastric tubes [ Back to EurekAlert! ] Public release date: 13-Apr-2013

Additional fluoroscopic and CT views can substantially reduce complications that occur during percutaneous radiologic gastrostomy, a procedure used for patients who require a gastric tube for nutritional support.

"In a study of 146 patients, we saw a major complications rate of 5.9%," said Dr. Erich Lang, of SUNY Downstate Medical Center, in Brooklyn, NY and lead author of the study. Major complications included organ injury with hemorrhage and colonic perforation, he said. Minor complications, such as tube leakage or dislodgement, occurred in 17.6% of patients, he said. "We were concerned with the high rate of complications, and we wanted to eliminate them."

"Topographic anatomic misjudgment appeared to be the cause for all major complications in this group of patients so we changed our technique to provide us with a better view," said Dr. Lang. In a follow-up study of 29 patients, we added fluoroscopy in oblique projection, cross table lateral fluoroscopy or biplane fluoroscopy, Dr. Lang said. "We virtually eliminated the problem of misplacement of gastrostomy catheters," he said. "By including CT in AP, lateral and oblique projection, we've eliminated improper passages of entry-tracts through other organs," Dr. Lang said.

It is important to note that surgical gastrostomy and percutaneous endoscopic gastrostomy two other techniques for insertion of feeding tubes -- have even higher rates of complications, said Dr. Lang. Surgical gastrostomy has a reported 74.3% complication rate, while percutaneous endoscopic gastrostomy has a reported 42.9% complication rate.

Dr. Lang's study is part of an electronic exhibit that will be available from April 13-April 19 at the ARRS Annual Meeting in Washington, DC.
