first_imgDear Editor:The outing in Hollywood of producers, directors, actors by survivors of this alleged sexual misconduct is freeing to all people who are and were subject to it.The survivors weren’t carrying this burden and secret any longer. The alleged perpetrators didn’t have power over them any longer. I say hurrah for their bravery and their courage. Let’s all stand together with the survivors. Regards,Renee Wallacelast_img

first_imgThe body of missing hiker Susan Clements was found in the Great Smoky Mountains National Park late Tuesday afternoon, a week after she went missing while hiking with her daughter near Clingmans Dome.Search crews found the body of Mitzi Sue “Susan” Clements approximately three-fourths of a mile south of the Appalachian Trail and two miles west of the Clingmans Dome parking area, according to a park news release. At 6,643 feet, Clingmans Dome is the highest peak in Great Smoky Mountains National Park, and surrounding terrain is some of the most rugged in all of Appalachia. Weather conditions near Clingmans Dome during the week of her disappearance included fog, wind, rain, and cold weather. Accordint to Park Service maps, her lcoation was near the headwaters of Higgins Creek in the vicinity of Loggy Ridge.Clements, 53, of Cleves, Ohio, had been hiking with her daughter on the afternoon of September 25. She and her daughter had hiked the Forney Ridge Trail from Clingmans Dome parking lot out to Andrews Bald. On their hike back, roughly a quarter-mile from Andrews Bald, her daughter hiked ahead to the Clingmans Dome parking area, hoping to squeeze in a hike to the Clingmans Dome lookout tower while she waited for her mom. Her mother never arrived at the parking area.After waiting in the parking lot and retracing their hike along Forney Ridge Trail, her daughter reported Clements around 5 p.m. that evening. Park officials searched the immediate area that night without success. They next day, a search and rescue team scoured the Appalachian Trail, interviewing hikers and searching for Clements.  They spent the night out on the trail.The Park Service closed Clingmans Dome Road and set up a search and rescue command post there. In addition to dozens of search and rescue teams, the Park Service used helicopters, canine teams, and drones to search for Clements.During the search, Clements’ family did not speak to the media during the search except to say she was a “wonderful mother to three children.” She was hiking with her youngest daughter on this trip.Clements worked for the city of Cincinnati’s Metropolitan Sewer District as an accounting technician in its administration department. Clements’ brother-in-law, who is a firefighter, and some of his colleagues traveled to the park to assist with the search.The Park Service did not release any additional details about the cause of death or how or where the body was found. Park officials previously said foul play was not suspected in Clements’ disappearance.last_img read more

first_imgBy Dialogo March 04, 2011 Good work… During a firefight, the last thing a machine gunner wants to do is stop fighting to change barrels, but that’s how it has always been done with standard, single steel-barrel machine guns. The reason for the barrel change is that at high temperatures barrels lose “strength properties,” according to engineers working on a promising alternative. One of the engineers is Vinny Leto, systems project engineer, of the Armament Research, Development and Engineering Center, or ARDEC, Weapons System Technology Directorate. During a test firing of a proof-of-concept barrel in December, Leto witnessed a measure of success with the High Performance Alloys for Weapons Applications Project. During testing, the first rifled, cobalt-alloy machine gun barrel ever produced using the “flow forming” process consistently reached high temperatures without degraded performance. The proof-of-concept barrel was made of an alloy that contains more than 50 percent of the metal cobalt. Cobalt alloys are erosion- and corrosion-resistant metals that are designed to retain high strength during long-term exposure to high temperatures. Cobalt alloys are frequently used in the aerospace industry, such as the hot-gas section of turbine engines, explained Leto. Cobalt alloys are also used as short liners for machine gun barrels. “If you look at steel in a machine gun environment, it gets very hot at a high rate of fire,” said Leto. “The benefit of the cobalt alloy is that it is designed to operate in high-temperature, high-stress environments. It has the added benefits of corrosion and erosion resistance.” While cobalt alloy barrel liners have been produced for years, it is very difficult with existing machining techniques to impart rifling. “The material, for all of its phenomenal properties, is very difficult to manufacture and machine,” said Leto. Different from machining, flow-forming is an advanced process used to manufacture precise cylindrical components. The process consists of high-pressure rollers exerting pressure on the exterior of a cylinder, pressing material against a rod-called a mandrel-on the interior of the cylinder. For this project, the flow-forming process was modified to produce the rifling in the barrel bore. More testing and data gathering will be required before engineers know if flow forming manufacturing can be achieved with the alloy. Success, however, would provide war fighters with three potential benefits: lightening their load, increasing barrel service life, and giving them a barrel that could operate at higher temperatures compared to a steel barrel, Leto said. Soldiers and Marines typically carry spare barrels into battle so that they have a cool barrel to exchange if they engage the enemy in a firefight, explained Leto. Having that strength at higher temperatures means that barrels may not need to be changed during a firefight, eliminating the need for the extra barrel and maintaining a steady stream of firepower. Engineering team members met all of their proof-of-concept test objectives when they fired more than 24,000 rounds and achieved an 1,100 degrees barrel temperature. Leto said the alloy barrel was fired from the ARDEC-designed Advanced Remote/Robotic Armament System. Steel begins to lose strength at approximately 1,000 degrees, Leto noted, and the test yielded data needed to assess and design the next round of improvements. The team is planning to produce another prototype that will be fired from a fielded infantry weapon later this year. Previously, the engineers had produced a half-length barrel as an initial demonstration of the flow-forming process before moving on to manufacturing full-length barrels. The Office of Naval Research assigned the engineers as principal investigators into the flow forming manufacturing technology. They are leveraging ARDEC’s expertise with metallurgy and small arms design and analysis. Prototype testing will be conducted here at the Armament Technology Facility, which is ARDEC’s small arms design and evaluation facility. Previously, the engineers had worked with the Office of Naval Research in development of lightweight 60mm and 81mm mortar tubes made with a nickel-based alloy. The team is also working with the Joint Services Small Arms Program, which is also based at Picatinny Arsenal. The JSSAP office oversees the day-to-day implementation of the plan by the joint services regarding the development and investment in small-arms technologies.last_img read more
