A technique for the examination of polar ice using the scanning electron microscope

first_imgThe microstructure and location of impurities in polar ice are of great relevance to ice core studies. We describe a reliable method to examine ice in the scanning electron microscope (SEM). Specimens were cut in a cold room and could have their surfaces altered by sublimation either before (pre-etching) or after (etching) introduction to the cryo-chamber of the SEM. Pre-etching was used to smooth surfaces, whilst etching stripped away layers from the specimen surface, aiding the location of particles in situ, and allowing embedded structures to be revealed. X-ray analysis was used to determine the composition of localized impurities, which in some cases had been concentrated on the surface by etching. Examining uncoated surfaces was found to be advantageous and did not detract from qualitative X-ray analysis. Imaging uncoated was performed at low accelerating voltages and probe currents to avoid problems of surface charging.last_img read more

Doctor unhappy with abortion stance

first_imgSouthland Times 4 August 2012A senior paediatrician who put in his letter of resignation in response to abortion services being offered at Southland Hospital  has retracted the letter on the promise that negotiations to reduce abortions will continue. Dr Vili Sotutu, who has been employed with the Southern District Health Board for four years, declined to speak with The Southland Times yesterday. However his wife, Ray Sotutu, confirmed Dr Sotutu put in his resignation last Thursday, but said his resignation had not been accepted. Last night, Mrs Sotutu said that after a 5pm meeting with management, her husband had retracted his resignation on the basis that the hospital work to help reduce the number of abortions performed. Mrs Sotutu, who is the rugby administrator at James Hargest College, said that she “absolutely” supported her husband’s decision, even if it had meant leaving Invercargill. She understood other doctors at Southland Hospital did not want to perform abortions, but none had put in a letter of resignation, she said. The couple were “very much” pro-life and she said the health board’s lack of consultation with the community over abortion services since it applied for a licence to perform abortions was disturbing.http://www.stuff.co.nz/southland-times/news/7412509/Doctor-unhappy-with-abortion-stancelast_img read more
