first_imgBy Sharon DowdyUniversity of GeorgiaUniversity of Georgia scientists are using DNA technology and old-fashioned animal instinct to find the best ways to control wood-destroying carpenter ants.“Carpenter ants are a major pest problem nationwide,” said Dan Suiter, an entomologist with the UGA College of Agricultural and Environmental Sciences. “They cause significant damage each year.”Wood-chewersUnlike termites, carpenter ants don’t eat wood. They chew it. “They expand it into a nest gallery that looks like Swiss cheese,” Suiter said. “Then they live in the galleries.” Carpenter ants are big and black and live mostly in trees, he said. In the Northeast, carpenter ants destroy more wood than termites.Based on the UGA Griffin, Ga., campus, Suiter and CAES genetic entomologist Tracie Jenkins test baits designed to kill the ants. They are monitoring 20 sites in the local city park because the hardwood trees there replicate those found in a typical suburban neighborhood. They monitor the test sites at night when the ants forage for food.Huge and nocturnal“During the day, they live up in the leaves and in hollowed-out tree holes and knotholes,” Jenkins said. “At night, they come down, and you can literally see the well-worn foraging trails they habitually use.”Ant samples are taken from the park back to the laboratory where Jenkins uses DNA biotechnology to determine the ants’ lineage or family relationships, which form colony structure.“We assume each colony has a single queen, so knowing the queen’s maternal fingerprint will help us track her progenies’ movements,” she said. “The winged ants are the ones that mate. We’ve discovered colonies that are physically far apart can actually be descended from the same female queen.”Once a colony’s genetic structure and movements are known, Suiter and Jenkins can develop management strategies and determine which baits are effective.Families don’t fightTo find out if colonies are related, Suiter said, you can also do what he calls “ant behavioral studies.”He places ants from different sites in a Petri dish. The ants that fight each other are not related.“The ants have colony-specific smells on their bodies,” Suiter said. Ants pick fights by using their antennae to spar, he said. Then it gets aggressive. “They grab each other by a leg, and one will take another’s leg off,” he said. “Then they lock jaws and do a circle-dance.”Deadly acidThen somebody brings out the heavy artillery.“Carpenter ants can spray formic acid,” Suiter said. “So, the first one to turn around and spray formic acid is the winner. It’s like getting a face full of tear gas, and they have to be very irritated to do it.”After six months have passed, Suiter and Jenkins will return to the test sites at the park. If they find ants, they will again take samples and run DNA analyses to determine if the ants are from the same colony that initially occupied the site.“We want to eliminate the ants in a colony by using the baits, then go back and see if the ants that come back are from the same colony,” he said. “To truly know how well the baits work, we have to know if the same colony of ants or a different colony move in after we eliminate the first colony.”To see carpenter ants, go outside after 9 p.m. armed with a flash light. “You may see a couple in the daytime, but you’ll see hundreds if not thousands at night,” Suiter said.last_img read more

first_imgDespite the increasing number of COVID-19 cases in Bali, the island has no intention of implementing large-scale social restrictions (PSBB) similar to those that are enforced in Greater Jakarta to stop the virus transmission.Bali Governor Wayan Koster claimed that Bali had yet to face a situation where such restrictions would be essential to apply, citing that the province had not even reached a high number of local transmissions.In a Monday press conference, Koster said implementing the large-scale restrictions would require at least two conditions.“First, the region would need to record many COVID-19 cases. Second, the spread of the virus would need to be high and have a big potential to cause fatalities and other misfortunes.“For Bali, referring to such requirements and my calculations […], it is not yet the time [for us to implement the restrictions]. We’re still quite far [from such conditions],” said Koster, who is an Indonesian Democratic Party of Struggle (PDIP) politician.Read also: COVID-19: Pekanbaru first area in Sumatra granted request to impose large-scale social restrictionsHe went on to say that Bali at the moment was not at the level of Jakarta, which is the epicenter of the COVID-19 outbreak in Indonesia with a high number of local transmissions. Koster said he was certain that the number of local transmissions in Bali was still low.Out of 81 cases recorded as of Monday, Koster claimed that only eight cases were caused by local transmission. “Most of the cases here are imported cases. Only eight people contracted COVID-19 through local transmission. I check the situation on a daily basis. The amount of local transmission is very small, in my opinion,” he added.Koster’s reasoning was based on what happened in Jakarta.Read also: COVID-19: West Java to request large-scale social restrictions for Greater Bandung“In Jakarta, the total number has reached 2,000 cases, and mostly from local transmission. “The capital is also connected with neighboring areas with high cases such as Banten, West Java — including Bogor and Bekasi — as well as Central Java,” he said.Koster claimed it was relatively easy to control the spread of COVID-19 in Bali as it is a small island. Nevertheless, his administration has applied limited access at all gates of Bali.The province is also focusing on repatriating thousands of Balinese migrant workers, considering that many COVID-19 cases were found in migrant workers who had just come home from working abroad.Topics :last_img read more

first_imgBentley plays in the five-team Chinook Hockey League, against teams from Fort Saskatchewan, Okotoks, Innisfail and Stony Plain.The Generals dominated the league, finishing in top spot with a 23-1 record.However, Macleod said the playoff run was anything but easy as Bentley won the league championship by defeating Innisfail in the final.“At the beginning of the year I was a little unsure I was making the right decision to play for the Generals but as the year went on, playing with the guys, in realized I missed hockey,” MacLeod, finishing the season with a goal and six assists in 13 games, said.The sour taste MacLeod experienced at the beginning of the season came from time toiling in the ECHL and SPHL.“I really didn’t like the business side of hockey,” said MacLeod, who played for South Carolina Stingrays, Columbus Cottonmouths and Stockton Thunder.MacLeod graduated from Nelson Minor Hockey before playing for Beaver Valley Nitehawks of the KIJHL.He joined Penticton of the BCHL before being traded to Camrose Kodiaks during his final season of junior hockey.MacLeod then spent four years on a NCAA hockey scholarship at Michigan Tech where he earned a degree in mechanical engineering.“I realized after a few seasons (of professional hockey) I wasn’t going to make NHL. I was happy to have an education and decided to go and start the next chapter of my life.”The Generals are 2-0 at the Allan Cup tournament with round robin wins over host Clarenville Caribous 3-2 and a 4-1 victory over Lameque Au Ptit Mousse from New Brunswick.Bentley now faces GF Windsor in semi final round action Friday with a win advaning the Alberta squad into the Final Saturday.MacLeod said the teams at the Allan Cup tournament are very evenly matched.“We could have just as been 0-2 as 2-0,” he said.“But we have a very deep teams and a great group of guys who are really fun play on the same team with.”A team with a Nelsonite playing that will hopefully give Nelson that historical Allan Cup victory. A hockey player from Nelson is trying to accomplish what no Nelson team has ever done before — win the Allan Cup, emblematic of Canadian Men’s Senior AAA Hockey supremacy.Nelson Minor Hockey grad Alex MacLeod is currently in Clarenville, Newfoundland playing in the six-team 2015 Allan Cup Tournament for the Bentley Generals.“I was pretty young when Nelson played for the Allan Cup,” MacLeod said from Clarenville where the Generals were enjoying a much-needed day off in preparation for a spot in Friday’s semi finals.“I remember hearing about Nelson playing in the 1965 and in the 80’s but that about it.”The Allan Cup is the oldest national championship in the country dating back 106 years as the best Senior hockey teams in Canada battled it out for the coveted prize.Nelson Maple Leafs were part of the Western International Hockey League, playing in three Allan Cup Finals in 1965, 1986 and 1987.The WIHL folded in the late 1980s.Playing in the 2015 Allan Cup tournament was probably the last thing on MacLeod’s mind when the season started for the Generals in the fall.Deciding to retire from professional hockey after a few seasons in the East Coast Hockey League and Southern Professional Hockey League, MacLeod was working as a mechanical engineer in Fort McMurray, Alta., when a friend told him about the Generals Hockey Club.“I asked him to gently tell the coach I was interested in still playing,” MacLeod explained.The rest, they say, is history as Macleod’s name was given to a company in Calgary that had an opening for — you guessed it — a recent mechanical engineer graduate.“It all happened within a few weeks,” MacLeod said.last_img read more

first_img23 November 2012 Football fans can expect a carpet-perfect pitch at Johannesburg’s FNB Stadium for the opening match of the 2013 Africa Cup of Nations (Afcon), says the City of Johannesburg. The FNB Stadium will host the Afcon opening ceremony and opening match on 19 January, as well as the final match and closing ceremony on 10 February. The pitch at South Africa’s flagship football venue was damaged during a Linkin Park rock concert ahead of the Nelson Mandela Challenge match between Bafana Bafana and Zambia a week ago.Semi-artificial surface for FNB Stadium Chris Vondo, member of the City’s mayoral committee for community development, said: “In terms of the pitch which appears to be bumpy, this matter to us is history. Come the opening day of the tournament, the pitch will be ready … we’ve ordered the desso, which is a long-term solution.” Vondo was speaking to reporters at FNB stadium on Thursday after making a presentation to the Afcon local organising committee (LOC) about Johannesburg’s state of readiness for the tournament. Desso is a sports playing field surface composed of natural grass combined with artificial fibres. The artificial grass fibres are injected 20 centimetres deep, and cover about 3 percent of the surface while the grass is growing; the roots intertwine with the artificial fibres. The 2010 Fifa World Cup in South Africa was the first international football tournament to be played on grass pitches partly made up of artificial grass. The system was installed at Nelspruit’s Mbombela Stadium and Polokwane’s Peter Mokaba Stadium. According to Vondo, the City of Johannesburg will install the desso after the Soweto derby between Kaizer Chiefs and Orlando Pirates on 8 December. There are fears that “the calabash stadium” will resemble a cabbage-patch for the derby because of a Lady Gaga concert taking place there on 30 November.City of Joburg ‘ready for Afcon’ Afcon LOC chief executive officer Mvuzo Mbebe reiterated that the pitch at FNB stadium would be ready for the opening match between Bafana Bafana and Cape Verde. “This pitch will be at the standard that we require it to be, whether there is going to be a concert or no concert between now and the tournament.” “The City of Johannesburg is quite advanced with their preparations, and we are happy with what we’ve seen in terms of their training venues, that include Dobsonville, Rand, Orlando and Milpark stadiums.” Mbebe said that the LOC was comfortable with the plan presented to it by the city. “What is left for all of us is to get the tickets and come to the stadium in large numbers on January 19,” he said. Afcon project coordinator for the City of Johannesburg, Bongi Bokaba said the city had lined up a series of events to make sure that there was maximum visibility and awareness about the tournament. “Our commitment is to ensure that our residents embrace the Afcon in line with the LOC’s call to action, which is ‘eyethu – Be Part of it’. “We want to use football to build social cohesion in the city, because we want Johannesburg to be the city of choice during the tournament,” she said.

first_imgHouston walk on scholarships awarded at team film session.YouTube/UHAthleticsWe can’t get enough of videos of college football walk-ons getting awarded scholarships. The life of a walk-on can be pretty thankless at times, especially when players have to balance schoolwork and all of the rigors of Division I athletics, without the benefit of a scholarship. A full ride can be life-changing for walk-ons and their families, and these videos always show how important those guys are to their teammates.On Wednesday, Houston head coach Tom Herman awarded two walk-ons—senior tight end Hayden Daniels and senior cornerback Tyler White—with scholarships for their final years. Herman was a bit tricky about it, opening by getting on the walk-ons who hadn’t yet had holds lifted by the university, chastising the group for a lack of “urgency,” before surprising the pair with their full rides. Daniels appeared in four games for the Cougars last year, while White played in all 13 games, registering 12 total tackles and fielding a crucial onside kick that helped spark Houston’s 35-34 comeback win over Pittsburgh in the Armed Forces Bowl.last_img read more

first_imgHALIFAX – Nova Scotia’s bid to become a world leader in tidal energy has been dealt a major setback, but industry experts say a French firm’s decision to pull out of a pioneering Bay of Fundy project may ultimately be good for the emerging industry.Stephen Dempsey, executive director of the Offshore Energy Research Association, says the renewable energy industry has been hurt by Paris-based Naval Energies’ decision to pull funding from its Dublin-based subsidiary OpenHydro, the key backer of Nova Scotia’s Cape Sharp Tidal.“When the leading technology developer exits the field, it’s a concern,” Dempsey said in an interview Monday. “There’s no way to diminish that. It will have immediate negative consequences. The question is whether it is short-term or long-term.”Last week, Cape Sharp Tidal successfully connected a massive, two megawatt in-stream tidal turbine to Nova Scotia’s electricity grid. It was the second time that Cape Sharp has installed a turbine on the floor of the Bay of Fundy to generate electricity from the world’s highest tides.In a historic first, Cape Sharp’s first turbine was hooked up to the grid in November 2016, but it was later removed for inspections and servicing in June 2017.In 2009, an in-stream prototype was torn apart by the bay’s powerful currents, which can move at 18 kilometres per hour.Naval Energies, considered a leader in the field of renewable energy, issued a statement last week saying it had stopped investing in tidal energy in Canada and in other locations, and was instead focusing on floating wind turbines and ocean thermal technology.“The deterioration of the market, in France and around the world throughout the recent months, has been reflected in a lack of commercial prospects over the long term,” company CEO Laurent Schneider-Maunoury said in a statement.The company also complained that in Canada “there is also great sensitivity to the cost of the technology.”Cape Sharp is a joint venture between OpenHydro and Halifax-based Emera Inc.Amanda White, acting executive director for Marine Renewables Canada, said her non-profit group was disappointed with Naval Energies’ move. However, she said such setbacks are to be expected in an emerging industry.“It has happened before in this industry and other innovative sectors, and is a natural part of industry development,” she said in a statement.“The association feels strongly that there is great opportunity in this industry with many promising projects on the horizon. Tidal energy is on the cusp of becoming a viable industry.”With OpenHydro now in the midst of bankruptcy protection, it will be up to the receiver, Grant Thornton in Ireland, to determine if a new owner can be found for the project.So far, officials with Emera Inc. have said little about what they plan to do. The company, which is the parent of the utility Nova Scotia Power Inc., issued a statement Monday saying Emera continues to believe in the potential for ocean energy.“These are still early days for a sector that is still emerging,” said spokeswoman Stacey Pineau. “The industry continues to learn and innovate so it can ultimately develop technologies that produce affordably-priced energy for consumers.”She said Emera’s biggest concern was ensuring the receiver has a plan for environmental monitoring and safe operation of the turbine.Nova Scotia’s recently appointed energy minister, Derek Mombourquette, did not directly respond when asked if the provincial government was considering some form of bailout.“We’re continuing to monitor the situation,” he said. “Our primary focus … is the environmental and marine regulations.”Mombourquette also said the industry is going through growing pains.“I still believe there’s great potential for Nova Scotia in the tidal energy sector,” he said. “There’s a number of players from around the world that are still involved.”Both Dempsey and White stressed that the end of Naval Energies’ involvement in tidal energy did not mean the end of research and development in the Bay of Fundy.Dempsey said a number of smaller companies are moving ahead with less ambitious projects.“There was never any certainty that (Cape Sharp) would be successful,” he said. “All of this feels kind of strange right now, but it was kind of anticipated. Often in technology developments, it’s the disruptive technology that ends of being successful. The big ones sometime start up and fail, and then others come forth.”In the coming weeks, U.S.-based Bigmoon Power is expected to deploy a 100-kilowatt prototype in the bay, using an onshore generator that is connected by high-strength ropes to a barge that will move with the tides.Meanwhile, Black Rock Tidal — a subsidiary of Schottel Hydro of Germany — is hoping to deploy a floating array of 40 small turbines that will be anchored to the floor of the bay.last_img read more
