Cosmonauts seal experiment A pair of cosmonauts in the Mir space station spent a fve-and-a- half-hour space walk to carry out an experiment on sealing minute cracks in the hul1 with specially designed glue. Cracks appeared when the station collided with a cargo craft in June 1997, and have caused constant air leakage from the cabin, forcing the crew to use more precieus energy to maintain normal pressure inside. Earher, other teams of cosmonauts tried to locate the puncture but failed. The latest attempt was said to be unsuccessful in stopping the pressure drop but mission control said experts believed the experience could be useful for further flights. Results of the experiment could come in handy during work at the International Space Station, the spokesman said, referring to a US$60 billion project in which Moscow is one of the main contractors after the USA. Russia says that Mir wil1 stay in orbit until at least August even though the cosmonauts also found that cables to a solar panel were blackened, indicating a short- circuit. Gasket problems delays launch Meanwhile, at Cape Canaveral, Florida, USA, the launch of the first US racket powered by a Russian designed and built engine was delayed because of a valve problem on the pad. Lockheed Martin Corp had hoped to have a fifth shot Sunday evening at launching its new Atlas 111 racket with a European communication satellite on board. However, when it was routinely draining propellant from the racket after the failed launch attempt, a gasket in the liquid oxygen check valve wore out and delayed the work. Technicians were replacing the gasket as wel1 as the rockets batteries. Ironically, the scheduled launch attempt had been scuttled by a fishing tournament that drew more than 70 boats into the launch- danger area offshore, and a last- minute computer error. Earlier delays were caused by technical problems and bad weather. Gaska Tape foam solves auto problems Gaska Tape Inc has published a white paper describing the versatility of the companys new Polymerie Series Foam Tape for automotive applications: Polymerie Series Foam Tape: Solutions for a Wide Range of Problematic Automotive Applications details actual case studies of how this new material meets or exceeds some of the toughest automotive specification for both exterior and interior applications. The new white paper also details how Gaskas new generation of Polymerie Series Foam, patent pending, has cleared the way to meet or exceed the SAB J 1756 out-gassing specification. This makes polymerie the first material of its kind to exceed this hurdle without the aid of masking or coating. Seals workshop suspended The US Federal Aviation Administration has suspended certification for some of Qantas Airways maintenance and engineering operations on US aircraft. The suspension applied to Qantas bearing and seal workshop that works on engine bearings, rotating parts and seals. Technicalities included the kind of solvents used and the surface material of the workshop floor. Qantas Airways says that the FAA issues do not affect the safe operation of its aircraft and that it was working on the FAAs concerns. Surgical sealant endorsed A US advisory panel has endorsed a surgical sealant made by Focal Inc for reducing or eliminating air leaks following lung surgery. A committee that advises the Food and Drug Administration unanimously recommended that the agency approve the sealant, known as FocalSeal-L, for marketing in the US. The sealant already is approved for use in Europe and Canada. The Lexington, MA, USA, based Focal hopes to sell the product in the USA market to prevent air leaks from occurring after surgery to remove lung tumours. If the FDA follows its panels advice FocalSeal-L would be the companys frst product approved in the US. There isnt anything more important than this, Focal president and chief executive officer Robert DePasqua said. Its nice to have approval for a product outside the United States, but our biggest markets are obviously here. The committee urged the FDA to require a warning on the products label that the clinical trial showed higher rates of wound infections and empyema, a collection of pus in a body cavity, in patients treated with the sealant than in the control group. They als0 recommended that the company conduct long-term studies to determine whether treatment with the sealant contributed to tumour growth. There needs to be further data accumulated before this question can be answered, said panel chairman Dr. Thomas Whalen, head of paediatric surgery at the Robert Wood Johnson Medical School in Camden, New Jersey.
