Advanced Characterization of Slags and Refractory Bricks Using Electron Backscatter Diffraction

Numerous studies have been conducted to determine changes that occur in slag that cause a rapid change in viscosity, but these studies have been limited by the inability to characterize/identify the phases present in the slag. Rapid freezing of slag in entrained gasifiers and slagging combustion systems can cause a shutdown of the system. The reactions occurring in slag that result in rapid freezing of slags are not well understood. It is believed that electron backscatter diffraction (EBSD) can be used to analyze slags and aid in their characterization although its use has not been found in literature. The EBSD technique allows particle-by-particle mineralogy based on diffraction patterns generated by the electron beam when the sample is tilted to a high angle. The diffraction pattern (Kikuchi bands) can only come from crystalline phases, which makes this technique ideally suited to study crystal formation in slags where oftentimes the crystals are very small and a reasonable chemical analysis cannot be made by conventional energy-dispersive spectrometry (EDS) methods in the scanning electron microscope. The ability to have mineralogical data based on the crystalline structure of a phase rather than a chemical analysis by EDS allows much better interpretation of the temperature regimes …

Oral History Interview with Ruben Peterson, June 30, 2007

The National Museum of the Pacific War presents an oral interview with Ruben Peterson. Peterson grew up in Madrid, Iowa and attended Iowa State College under the Navy’s V-5 Aviation Program, where he enrolled in flight training. He was transferred to the University of Georgia in January 1943 where he continued flight training. After three months he was transferred to Pensacola where he received his wings. He trained in Douglas SBD Dauntless dive bombers, but he preferred fighter aircraft and volunteered to fly night fighters. In June 1943 Peterson was transferred to Quonset Point, Rhode Island, where the Navy established a base to train night flying on carriers in Grumman Hellcats. He qualified in carrier night flying and was transferred to Barbers Point, Hawaii. He embarked on the USS Independence (CVL-22) on 1 September 1943 and sailed to the South Pacific. While there, he shot down a Japanese bomber, and made bombing runs on freighters and ships near Leyte, flying only in daylight due to Admiral Halsey’s aversion to night carrier missions. Admiral Halsey’s relief had no such reluctance, and night flying became common. He remembers one close call at night in thick fog when he could not locate the …

Freedom of Information Act: Processing Trends Show Importance of Improvement Plans (open access)

Freedom of Information Act: Processing Trends Show Importance of Improvement Plans

A letter report issued by the Government Accountability Office with an abstract that begins "The Freedom of Information Act (FOIA) establishes that federal agencies must provide access to their information, enabling the public to learn about government operations and decisions. To help ensure proper implementation, the act requires that agencies report annually to the Attorney General, giving specific information about their FOIA operations, such as numbers of requests received and processed and median processing times. Also, a recent Executive Order directs agencies to develop plans to improve FOIA operations, including decreasing backlog. For this study, GAO was asked to examine the status and trends of FOIA processing at 25 major agencies as reflected in annual reports, as well as the extent to which improvement plans contain the elements emphasized by the Executive Order. To do so, GAO analyzed the 25 agencies' annual reports and improvement plans."

He provides some detail of working aboard a submarine, serving as the Doc, living conditions and undergoing his own appendectomy aboard the Apollo. In early 1945 he was assigned for 1 year to serve at a submarine base in St. Thomas. He then served as hospital corpsman on the USS Clamagore (SS-343). Keeton also worked on sonar watch, radar watch and as a cook during his time in the Navy. He spent a total of 30 years in the Navy, retiring in February of 1972.

Oral History Interview with William Smart, October 30, 2007

The National Museum of the Pacific War presents an oral interview with William Smart. Upon graduating from junior college Smart joined the Naval Aviation Cadet Program. Having civilian pilot experience, he quickly advanced from platoon leader to company and battalion commander. Smart first joined the experienced VMSB-141 before joining VMSB-236 at Bougainville. His first combat experience involved bombing Rabaul. Smart then supported the Army in the Philippines by bombing assigned buildings and strafing enemy troops. Although Smart was fortunate enough never to encounter enemy aircraft, antiaircraft fire struck his plane in the oil cooler system, forcing a crash-landing on a guerrilla airstrip. There he was warmly received and gifted a homemade knife and scabbard by a headhunter. Later, during the Luzon campaign, Smart bombed Santo Tomas following the liberation of American prisoners and felt it was a privilege to do so. After war ended, Smart joined the Marines as a reserve pilot and had duty in Japan. He lived there with his wife and children and was amazed by how much the Japanese accepted them as allies, so soon after the war.

The National Museum of the Pacific War presents an oral interview with Al Kiracofe. Kiracofe was born in Gratis, Ohio in 1917 and graduated from high school in 1935. Entering the Navy in October 1942 he became a Commissioning Yeoman and participated in the forming of the Navy’s first five night-fighter units at Quonset Point, Rhode Island. He relates the experience of participating as a flying target for night-fighter pilots in training. He was assigned to Air Group 10 aboard the USS Intrepid (CV-11) in January 1945. Following the shakedown cruise the ship was deployed to Ulithi. Kiracofe tells of being on board the ship when it was hit by a Japanese suicide plane, which killed a number of sailors and heavily damaged the ship. The Intrepid returned to the United States for repairs and Kiracofe reported to the Oakland Naval Hospital. After receiving treatment for several months he received a medical discharge.

Patterns and Implications of Gene Gain and Loss in the Evolution of Prochlorococcus

Prochlorococcus is a marine cyanobacterium that numerically dominates the mid-latitude oceans and is the smallest known oxygenic phototroph. Numerous isolatesfrom diverse areas of the world's oceans have been studied and shown to be physiologically and genetically distinct. All isolates described thus far can be assigned to either a tightly clustered high-light (HL)-adapted clade, or a more divergent low-light (LL)-adapted group. The 16S rRNA sequences of the entire Prochlorococcus group differ by at most 3percent, and the four initially published genomes revealed patterns of genetic differentiation that help explain physiological differences among the isolates. Here we describe the genomes of eight newly sequenced isolates and combine them with the first four genomes for a comprehensive analysis of the core (shared by all isolates) and flexible genes of the Prochlorococcus group, and the patterns of loss and gain of the flexible genes over the course of evolution. There are 1,273 genes that represent the core shared by all 12 genomes. They are apparently sufficient, according to metabolic reconstruction, to encode a functional cell. We describe a phylogeny for all 12 isolates by subjecting their complete proteomes to three different phylogenetic analyses. For each non-core gene, we used a maximum parsimony method to …
