Contact Information Available for logged-in reporters only Newswise A geostatistical approach for studying environmental conditions in stream networks and landscapes has been successfully applied at a valley-wide scale to assess headwater stream chemistry at high resolution, revealing unexpected patterns in natural chemical components. Headwater streams make up the majority of stream and river length in watersheds, affecting regional water quality, said Assistant Professor Kevin J. McGuire, associate director of the Virginia Water Resources Research Center in Virginia Techs College of Natural Resources and Environment. However, the actual patterns and causes of variation of water quality in headwater streams are often unknown. Understanding the chemistry of these streams at a finer scale could help to identify factors impairing water quality and help us protect aquatic ecosystems, said Gene E. Likens, president emeritus and distinguished senior scientist emeritus with the Cary Institute of Ecosystem Studies and the University of Connecticut. Results of the study that used a new statistical tool to describe spatial patterns of water chemistry in stream networks are published in the April 21 issue of the Proceedings of the National Academies of Science by a team of ecosystem scientists, including McGuire and Likens. The data used in the new … Continue reading →

When you have done Strictly live on a Saturday night in front of millions, Ill never be that nervous again, she said. Becoming a household name has come at a considerable cost to the 43-year-old mother of three, with the breakdown of her 12-year marriage to Dominic Cotton, a sports journalist, stirring talk of the Curse of Strictly. The toll on the shows stars down the years has been harsh: Countdown presenter Rachel Riley left her husband; newsreader Natasha Kaplinsky broke up with her boyfriend; Denise van Outens marriage collapsed; Joe Calzaghe relationship with his dancing partner Kristina Rihanoff did not last. Reid hints that it was her 1,200-mile a week commute from London to Salford to present BBC Breakfast that placed a greater strain on her marriage than her brief spell in sequins and spandex. Yes, there are new routines as my working pattern has changed, she said. I get to do the school run when a lot of working mums dont get home until bedtime. Of course, I will bring this side of me to the programme: as a journalist, you bring all of your experience. Despite the roll call of stars who have failed to revive ITVs … Continue reading →

Aug. 20, 1924 April 8, 2014 Albert A. Himmel, a chemistry professor and avid fisherman who also wrote for many publications about both of his interests, died April 8 at his home in West Seneca. He was 89. Mr. Himmel was born in the Town of West New York, N.J., across the Hudson River from Manhattan. He served with the U.S. Armys 279th Engineer Combat Battalion during World War II in the European Theater. A graduate of Syracuse University, Mr. Himmel moved to Western New York in 1962 and took a position teaching chemistry at Buffalo State College. He retired 25 years later as a full professor. But it was fishing that was his passion. Mr. Himmel was a lifelong member of Trout Unlimited and was the author of seven fly-fishing booklets on such topics as identifying insects and salmon fishing in New York State. His work appeared in Fly Fisherman magazine and the Catskills Fly Tyers Guild Gazette, along with other newsletters and publications, including The Buffalo News, and his reputation in the regional fly fishing community has been described as legendary. Michael Levy, the late News outdoors writer, once quoted Mr. Himmels monograph What Every Trout Should Know … Continue reading →

5 hours 55 minutes ago by Monique Padia TUCSON - Pima Community College faculty member, Katherine I. Feuling, was awarded for her dedication and excellence in teaching chemistry. Feuling was awarded at the East Pima campus with its "College Educator Excellence in Teaching Award". On April 23rd, the Southern Arizona Chapter of the American Chemical Society will grant Feuling with her award during a reception at the Casa Vicente Restaurante Espanol, 375 S. Stone Ave. "In more than 25 years of teaching at Pima, I have been privileged to instruct some very outstanding students who have or will go on to make their mark in the world," Feuling says. "But even more than that, I have been blessed to know many, many inspiring individuals who chose to come to Pima and, whether or not chemistry was their strong suit, have made my career a very satisfying and rewarding one." Feuling is just one of the many PCC faculty members to receive this award. Last year, Pollyanna Wikrent, a PCC full-time chemistry faculty member at Desert Vista Campus, also received the award. The award is given out annually to recognize excellence in teaching chemistry, biochemistry or a chemistry-related field at a … Continue reading →
