The population structure and transmission of Escherichia coli in an isolated human community; studies on an antarctic base

first_imgThe population structure and transmission of Escherichia coli in a small group of individuals isolated for 26 weeks on an Antarctic base were studied by multilocus electrophoresis of eight enzymes and plasmid analysis. Two hundred and sixty-nine strains were isolated. They were grouped into 60 allozyme types (ETs). Half of these ETs were only isolated once; others were repeatedly isolated from single subjects. Eleven were found in more than one subject and the pattern of the occurrence of some of them was considered to provide evidence of their spread from subject to subject.last_img

Examining local time variations in the gains and losses of open magnetic flux during substorms

first_imgThe open magnetic flux content of the magnetosphere varies during substorms as a result of dayside and nightside reconnection. The open flux can be calculated from the area of the polar cap, delineated by the open‐closed field line boundary (OCB). This study presents a superposed epoch analysis of the location of the OCB and the change in the magnetic flux content in individual nightside MLT sectors during substorm growth, expansion and recovery phases. Far ultraviolet (FUV) observations from the IMAGE satellite are used to derive a proxy of the OCB location. In the hour prior to substorm onset, the total nightside flux content increases by up to 0.12 GWb on average, resulting in an equatorward expansion of the OCB. Following substorm onset, the OCB contracts towards the pole as the open magnetic flux content decreases by up to 0.14 GWb on average but the rate of decrease of the total nightside open flux content differs by 5‐66% between the three IMAGE FUV instruments. The OCB does not contract poleward uniformly in all nightside MLT sectors after substorm onset. Close to the substorm onset MLT sector, the OCB contracts immediately following substorm onset however the OCB in more dawnward and duskward MLT sectors continues to expand equatorward for up to 120 minutes after substorm onset. Despite the continued increase in flux in these sectors after substorm onset, the total nightside flux content decreases immediately at substorm onset, indicating that the nightside reconnection rate exceeds the dayside rate following substorm onset.last_img read more

USA: NAVFAC Mid-Atlantic Recycles Debris from Hurricane Sandy

first_img Share this article View post tag: Debris View post tag: Hurricane View post tag: Defense View post tag: NAVFAC Naval Facilities Engineering Command Mid-Atlantic will recycle more than six miles of damaged metal pipes from Naval Weapons Station Earle, in a project that began Dec. 14, saving the Navy more than $150,000 in refuse removal fees for the material.According to Dave North, Naval Weapons Station Earle recycling specialist, Hurricane Sandy destroyed three to four miles of 10 inch sewer pipe and three to four miles of 14 inch water pipe, primarily from the three-mile long pier at the base. Personnel at Earle originally studied possibly reusing the pipe, but discovered the pipe was too damaged for that to be feasible.“Our mission is to be fiscally responsible and to be good stewards of the environment,” said Mike Cunningham, NAVFAC Mid-Atlantic regional integrated solid waste manager. This project not only saves the Navy money through cost avoidance, but it helps to reduce landfill space by maximizing our diversion efforts.”According to Brian Grandinette, NAVFAC Mid-Atlantic solid waste manager for New Jersey and Pennsylvania, the estimated cost for removing the debris and sending it to the landfill was more than $150,000.“We won’t make any money off this due to the labor and time required for our recycling vendor to retrieve the material, but they won’t charge us either,” he explained.NAVFAC Mid-Atlantic is working with a local vendor, Red Bank Recycling to remove the plastic and foam from the pipes and recycle the metal. The effort will wrap up with the vendor clearing the area and the entire project should be finished by the end of December.[mappress]Naval Today Staff, December 23, 2012; Image: US Navy December 23, 2012 View post tag: Warship Industry news View post tag: Recyclescenter_img View post tag: Navy View post tag: Defence View post tag: Sandy View post tag: News by topic USA: NAVFAC Mid-Atlantic Recycles Debris from Hurricane Sandy View post tag: Mid-Atlantic View post tag: Naval Back to overview,Home naval-today USA: NAVFAC Mid-Atlantic Recycles Debris from Hurricane Sandy last_img read more

Leis show support for Te’o

first_imgAfter losing his grandmother and girlfriend within hours of each other last week, Irish linebacker Manti Te’o could have left Notre Dame and his teammates to be with his family in Hawaii. Instead, he stayed in South Bend and led his team to a decisive victory at Michigan State on Saturday. This Saturday, under the Notre Dame Stadium lights, tens of thousands of Fighting Irish fans will return the favor and display their support for Te’o during his time of loss by donning leis at the football team’s night game against Michigan. The “Wear a Lei for Manti” campaign was conceived at a Monday night meeting of the Leprechaun Legion when the student spirit group discussed the possibility of giving out leis to students at the pep rally before the Michigan game, senior and Legion football leader Rosemary Kelly said. “The idea was suggested at the Legion meeting in recognition of Manti’s allegiance to Notre Dame, his sacrifice to stay an extra year and his decision to play in the Michigan State game under personally difficult circumstances,” she said. “As students, we want to do our part and let him know that we value his contributions and support him as a man of Notre Dame, on and off the field.” Coincidentally, a similar idea was posted by someone unrelated to the Legion on the social media pages of The New ND Nation (TNNDN), a Notre Dame fan group committed to positive attitudes toward the school, within hours of the Legion’s meeting, Kelly said. Lynne Gilbert, a TNNDN volunteer who manages the group’s Twitter account, said the group helped publicize the idea via Twitter and Facebook on Monday. By Tuesday morning, a local South Bend radio station contacted Gilbert to discuss the lei campaign. “[The idea for the campaign] just blew up on Monday after we asked our Twitter followers what they thought of it,” she said. “We started a Facebook event page, ‘Wear a Lei for Manti,’ that now has 4,000 members, so it’s just been growing and growing.” The social media-driven publicity helped the Legion find a way to distribute leis to students without violating NCAA compliance rules about paying for promotional items in Te’o’s name, Kelly said. “We had to figure out how to pull it off without spending any money,” Kelly said. “Fortunately, a flurry of social media in the last few days has garnered support for the movement, and less than 24 hours after the idea surfaced, we had a donation for the pep rally, and we now have an opportunity to make the idea a reality.” Kelly said United Beverage Company of South Bend volunteered to donate 7,500 leis to the Legion to be distributed at Friday’s pep rally. At least 25,000 leis will be distributed Saturday from various sources, Gilbert said. Budweiser and WSBT have partnered to donate 10,000 leis for students on gameday, Brothers Bar and Grill will contribute 1,000 leis to the campaign and TNNDN purchased 500 leis with out-of-pocket money and donations received through its website. Gilbert said TNNDN’s goal in supporting the lei campaign was rooted in the group’s love for Notre Dame. “We really just want to give back to Manti and the whole team. Look what he’s done through adversity … just going out there and playing with his heart and putting it all on the field,” she said. “It’s a different atmosphere and the team is so unified, so anything we can do to give back to them, we want to do.” As a member of Notre Dame’s student community, Kelly said the movement holds even greater meaning. “Hopefully students will take a moment to think about what the lei means as they put it on. It is a sign of affection for Manti and a symbol of our support for him,” she said. “It is a nod toward what we, as a community, hold to be important in our representative student-athletes, and after this week, I think each student on campus will have a new awareness of just how tight-knit the Notre Dame community is and will realize that community does not end at campus boundaries.” For more information, visit TNNDN’s website,, and the Facebook pages of TNNDN and the Leprechaun Legion.last_img read more

ND freshmen take part in revamped Welcome Weekend

first_imgThe class of 2019 spent its first days at Notre Dame participating in events organized by the University and its 29 residence halls during this year’s Welcome Weekend, formerly known as Frosh-O. Over the course of the weekend, freshmen partook in a variety of activities alongside their classmates and older student ambassadors, which were designed to make the first-year students feel comfortable as they adjust to life away from home.Michael Yu | The Observer Freshman Andy Nelson said he felt a sense of belonging within the Notre Dame community when he pulled up to Morrisey Hall for the first time.“I just opened my car and everyone helped take my stuff to my dorm room,” Nelson said. “It helped me feel welcomed. Everyone had Morrisey T-shirts on and when I got mine, I just felt like part of the group.”Nelson said he enjoys the energy, community and faith that he has experienced at Notre Dame.“I went to a Catholic grade school and high school, so I’m kind of used to Catholic schooling,” Nelson said. “I liked how faith is an important part of school here at Notre Dame. Over Welcome Weekend, we had a lot of stuff centered around faith, like the opening Mass and the visit to the Grotto.”Welcome Weekend was led in the dorms by staffs consisting of current student ambassadors who worked to help the first year students move in and transition into their lives at Notre Dame.Junior Maggie Blake, Walsh Hall’s Welcome Weekend captain, said she thought this year’s Welcome Weekend was the best one yet. Blake said an event called “Ice Cream on Ice” was her favorite.“We did an event with Keenan where we went ice skating at Compton and ate ice cream,” Blake said. “It was so much fun. Everyone was having a blast and everyone skated, even the people who didn’t really know how to or went in not wanting to.”Blake said she wanted to highlight the sense of love and community within Walsh for the first year students.“I remember when I was I freshman, I was really nervous coming in,” Blake said. “Just coming to this place, where people love each other so much, made me feel way better.”Freshmen Kimberly Faust and Caroline Forlenza, roommates in Farley Hall, said their residence hall’s Welcome Weekend staff made them feel comfortable and excited to begin their time at Notre Dame.“They were really helpful just while moving us in and helping us organize our furniture,” Faust said. “I didn’t expect them to carry all our stuff for us.”Forlenza said she felt a sense of unity with her new classmates after the weekend.“When we were all at the Grotto, we were holding candles and they read aloud some of the concerns I’ve felt,” Forlenza said. “It was nice to hear that everyone’s feeling the same way.”Junior Jay Dawahare, the Welcome Week captain in Alumni Hall, said his favorite part of the weekend was teaching Alumni’s serenade songs to the first year students.“Every year we teach the Pups ‘My Heart Will Go On’ by Celine Dion,” Dawahare said. “The words are easy enough to teach, but the emotion behind the song and dance takes a skilled and passionate staff. Usually the Pups laugh at us at first, but by Sunday night you can see a few Pups serenading the women.”Dawahare said Welcome Weekend was a success, although he said he felt some of the changes this year have hindered the ambassadors’ abilities to welcome new students. Alumni Hall was unable to host its traditional Dawg Run across campus, according to Dawahare.“In general, there is too much emphasis on one individual, instead of the group,” Dawahare said. “Because a couple people might not want or be able to fully participate, they shut down the whole event. There are carts as an option for people unable or unwilling to run so they are able to ride alongside.”Dawahare said he presented Alumni Hall as a home and family to its new residents.“My goal was and still is to foster the sense of brotherhood and community that Alumni Hall is known for, and that has been integral to my experience at Notre Dame,” he said.Tags: Alumni Hall, Class of 2019, Frosh-O, Grotto, Welcome Weekendlast_img read more
