BOGOTÁ — Soldiers stretch on the parade grounds and playing field of the Escuela de Ingenieros Militares as if preparing for a sporting event. Lighthearted banter fills the Bogotá morning air. But despite appearances, serious work has begun: these are military personnel who have been injured and, in many cases, severely maimed by landmines. All but one of Colombia’s 32 departments are cursed with landmines, and at Bogota’s Centro de Rehabilitacion del Ejercito (CRE), everyone is all too aware of the damage and suffering wrought by these instruments of war. The clinic, officially known as the Batallón de Sanidad, serves as an office and rehabilitation center and is manned by doctors, therapists, social workers, orthopedic surgeons, psychiatrists and physiotherapists. All these health professionals are here to attend to those wounded by homemade landmines that plague Colombia’s rural areas. No single armed group in Colombia is solely responsible for these artisanal “quiebrapatas” or leg breakers, constructed from deadly explosives and hidden in ordinary household containers like plastic bottles and bags to waterproof them. The Revolutionary Armed Forces of Colombia (FARC), the National Liberation Army (ELN) and the paramilitaries typically use the same approach: place these booby-trapped devices to inflict as many casualties as possible, chasing villagers from strategic positions. In many cases, landmines have been hidden on or near paths leading to a town’s water source. Now, the Colombian Army’s Engineering Division – and the “Coronel Gabino Gutiérrez” Battalion in particular, which is dedicated to demining secured towns and rural areas – has taken on the role of “humanitarian demining.” But there still is much work to do. This year, Cadena’s team hopes to finish demining the towns of Zambrano in Bolivar, Carmen de Chucuri in Santander and Granada in Antioquía. Overall, 72 municipalities in 12 departments across Colombia have been given priority for this project. The key, said Cadena, is that each of these towns receiving humanitarian aid from military engineers must promise to reactivate the local economy. For example, Granada — in the department of Antioquía — is located just eight miles from the main highway linking Bogotá and Medellín. Due to Granada’s precarious situation, this short trip over mountainous terrain used to take six hours. Now, says Cadena, “it can be done in 40 minutes.” Antioquia is relatively accessible compared to the other Colombian departments most affected by mines – Putumayo, Cauca, Caqueta, Nariño, Meta and Norte de Santander. Virtually all of Colombia’s landmines are found in these mountainous, rural areas. The complexities of the civil conflict and the topography make the military engineers’ jobs particularly tough. And three years of heavy rains have triggered landslides throughout Colombia, displacing landmines and shifting their positions significantly. San Carlos is a success story Demining process continues in earnest While spirits are high here around the sports field, and those soldiers fortunate enough to have survived landmine explosions are under constant supervision, Ortiz observes that “each exploded mine, in general, represents one death and one injured.” And this is where Maj. Sara Reyes takes over as the leading physician in charge of rehabilitation here in Bogotá. As a veteran doctor with 14 years of military experience under her belt, the major has pretty much seen everything. “The issue with landmine victims is that this is an injury with massive impact but — over time and after rehabilitation — one which causes the least limitations in the victim’s lifestyle. Most of our soldiers injured by landmines who arrive here are between 16 and 29 years old, and this gives them far more opportunity to recuperate well.” So far this year, Reyes has treated 56 amputation cases; that compares to 274 cases in 2011. “A soldier’s recuperation owes a great deal to his or her personality and desire,” she said. “If that soldier does not have the emotional capacity or willpower, we cannot progress.” Interesting article, but I would like to get something straight: all the images that are shown here, were taken in the Health Battalion of the National Army, not at the Military Hospital. Thanks a lot. You are all so cute, killing yourselves for our peace. This ambitious effort differs from conventional military practice in that three steps take place before demining begins, said Col. Carlos Ivan Cadena Montenegro, commanding officer in charge of the humanitarian demining division. “In March 2011 we were able to completely rid perhaps one of Colombia’s most violent towns — San Carlos, Antioquía — of landmines,” he said. “It was the first town to achieve this status in Colombia. First, the town had been secured from all aggressors. In the case of San Carlos, the local FARC militia had demobilized, permitting us access. Second, the municipality requested our help, and third, we can ensure there will be no further conflict in this town.” San Carlos was an extreme situation, he said, passed back and forth between FARC guerrillas, ELN rebels and then various paramilitaries over the years. Even the town’s central plaza – just 67 miles from the bustling city of Medellin, and neighboring the popular weekend destination and resort town of Guatape – had to be demined. “We were able to secure the return of 2,500 displaced families to San Carlos, a total of 10,000 people driven from their homes,” Cadena said. The Presidential Program for Comprehensive Action Against Antipersonnel Mines (PAICMA) estimates that 65 per cent of all municipalities in the country are affected by landmines. And at least 9,884 soldiers and civilians have been victimized by landmines since 1990, according to PAICMA – including 2,204 in Antioquía alone. At least 1,065 Colombians were killed or maimed in 2005 by stepping on mines — more than either Afghanistan or Cambodia, countries that have been ravaged by civil war. FARC, ELN and other violent groups have planted more than an estimated 100,000 explosive devices to protect cocaine crops. Many soldiers stationed in troubled areas and subsequently injured by landmines end up in the CRE’s Batallon de Sanidad in Bogotá. Col. Javier Ignacio Ortíz Rozo, the commanding officer in charge of the Batallon de Sanidad, is a much sought-after man. All medical staff and wounded servicemen here report to him. “The degree of rehabilitation required depends wholly on the amputation and the soldier’s state of mind,” said Ortíz, who deals not only with amputees from landmines but also victims of leishmaniasis and post-traumatic stress disorder. “On average, most servicemen stay here for six months before they are well enough to leave. We treat between 230 and 250 soldiers annually who have been injured by landmines.” Ortíz’s job is no easy task and not one he can leave behind at the base when he goes home each evening. “I have to treat each person the same as I would anyone else, amputee or not,” he said. “If I don’t force them to get up out of their wheelchair and engage in rehabilitation, they will never succeed.” PAICMA: Nearly 10,000 landmine victims since 1990 By Dialogo June 18, 2012 Attitude is everything when it comes to recovery
Sea Bright Borough officials are looking to demolish the storm-damaged century-old police headquarters and firehouse and replace them with new buildings. Photo courtesy Christopher ClarityTHE BOROUGH COUNCIL, at its regular meeting on April 7, passed a resolution that authorized advertising to obtain bids to for the demolition of the firehouse and the police headquarters.Because of damage the buildings received during Super Storm Sandy in October, 2012, the fire and police departments have been operating out of temporary quarters.The police headquarters are in trailers located near the old office and the fire department is on South Street.In a March, 2014 interview, Police Chief John Sorrentino said of the police department and first aid headquarters that “We found mold in the floor and in the walls.”“Every wall in this building had water in it from Sandy. The roof leaked from Sandy. The water came in the doors from Sandy,” he said.Sorrentino said that the main part of the building that housed the police and first aid building is about 100 years old with additions around 80 years old.The firehouse was condemned after building officials said it was unsafe to be occupied.Borough Administrator Joseph Verunni said Wednesday that plans call for two new buildings, the expected cost of which would be about $11 million. The Federal Emergency Management Agency (FEMA) would pay up to 90 percent of the cost, he said.Sea Bright Fire Dept. building. Photo courtesy Christopher ClarityOne building would be placed on the foot- print of the existing firehouse, Verunni said, and would contain the fire department and police headquarters. The other would serve as a community center and contain facilities for the beach, including rest rooms and lifeguard quarters, and public meeting rooms and the town’s library, he said.The total new space would be 5,000 square feet for the beach building and 9,500 square feet for the other building, according to Verunni.He said this would be less than the footage of the four buildings; the firehouse, police headquar ters, the librar y and the beach pavil- ion that were being replaced.The new buildings, Verunni said, would have to conform to FEMA requirements. They have “to go up in the air on pilings,” he said, and the utilities will be run from the top down.He said the future of the existing Borough Hall is still under discussion.The large room in the Borough Hall that was previously used for community meetings is no longer available since Sandy, Verunni said, because the borough staff for the many services that are now needed because of the storm is now using it. The room has to be locked at night, he said for both privacy and security reasons since public records are being stored there.Verunni said that there would be about an 18 month to two-year period before the new buildings would be in service.
Impact on public schools is a concernBy John BurtonRED BANK – A plan to double the size of Red Bank Charter School is necessary in order to meet the needs of the entire community, said Meredith Pennotti, the charter school’s principal.But some traditional public schools supporters fear the increased size would compromise the budgets, resources and extracurricular activities for Red Bank’s diverse school population.And there are the taxpayers, who wonder what it would mean for their property tax bills – should the plan move forward.“The reality is this is not good for the children of Red Bank. It’s not good for the taxpayers of Red Bank. It’s not good for Red Bank,” stressed Jared Rumage, Red Bank superintendent of schools.“We feel we have a model that can be shared more in Red Bank,” for the educational community’s betterment, Pennotti said of the plans.In December, The Red Bank Charter School, 58 Oakland St., submitted a proposal to state Department of Education (DOE) Commissioner David Hespe in Trenton to increase enrollment and facility.Hespe is expected to make his determination toward the end of February, according to DOE spokesman David Saenz.The plan calls for doubling the school’s current student population to 400 from its current 200. That would be done over a three-year period period. In essence, it means adding an additional class of students per grade for the pre-K-8th grade school, according to Pennotti.For the past three years, Pennotti said the wait list for students has been “robust,” roughly 112 students, believing that filling the additional 200 seats is an easy call.The “clincher” for school officials in favor of seeking the expansion, according to Pennotti, was the availability of an adjacent property, 135 Monmouth Street, which the school would use for its S.T.E.M. (science, technology, engineering and math) lab and additional classroom and activity space.Another deciding factor for the school is recent changes in state education policy that allow other factors to be considered when evaluating students’ and families’ socio-economic status as part of admission.Charter school students are selected by an annual lottery, but siblings are accepted without submitting to the lottery. Last year, however, DOE officials changed the lottery to give more weight to family income and other factors, to give those students a better chance to be selected.“This will increase our ability to serve the economically disadvantaged,” Pennotti said.The charter school is increasing its community outreach by mailing a bilingual application to every residence in the community that also makes families aware of the changes in the lottery system, according to Pennotti.Concern about how a proposed expansion of the Red Bank Charter School could impact public schools drew people to the borough’s middle school auditorium Wednesday. They marched to the Borough Council meeting at Borough Hall. Photo: Tina ColellaThe fact that the charter school population is significantly less diverse than the public school population and the community at large has long been a source of contention. Early in the charter school’s history, which was established in 1998, the district Board of Education waged a lengthy and rather bitter legal battle arguing the school allowed for creating a segregated school district, providing for “white flight” from the public school – on the taxpayer’s dime. The lawsuit was eventually unsuccessful and the two entities had entered into a sort of separate peace, letting live and let live, until this development.Increasing the enrollment, fears Rumage, “It is fairly accurate to say that funding would double over that period.” And given the state finances, no one expects funding from Trenton to increase in an appreciable way, he added.The public school district is currently required to provide $1.67 million for the 2015-2016 school year to cover 90 percent of the cost to provide under state guidelines what is determined to be a “thorough and efficient education.” It is up to the charter schools to find the additional 10 percent of the cost and provide and upkeep a facility.Should the state education commissioner allow this plan, departing students will result in less state education aid to the district. And that Rumage maintained, would mean having to raise property taxes, likely to the maximum 5 percent cap, to cover some of the shortfall. And given those limitations, he said, the likely scenario would mean cuts to programs, possibly eliminating positions and abandoning some programs.“It will lead to cuts here that will be devastating,” Rumage said. “I can’t emphasize that enough.”Pennotti countered, saying state aid dollars follow the student, so that money wouldn’t have gone to the district anyway and any decision the charter school makes has no impact on the public school budget.“What happens to the tax rate is the decision the borough makes in its spending,” Pennotti argued, referring to the borough board of education. “We have no input in the school budget.”The charter school was established by activist parents in the late 1990s when Gov. Christine Todd Whitman signed the legislation allowing for such schools to operate. In Red Bank the school was in response to a failing public school district, with rundown facilities and dismal test scores.Charter schools are public schools but have greater freedom and are exempt from much of the bureaucracy that critics say bogs down traditional public education. This freedom, charter school supporters argue, allows for more creative and effective education and gives families a choice.Families braved bitter cold Wednesday night to express concern about proposed plans for a charter school expansion. Photo: Tina ColellaRumage insisted, “I’m not anti-charter school. I’m just anti-expansion,” at this point. He hoped the charter school would postpone the expansion to give the district time to evaluate its situation.Pennotti dismisses the idea of waiting. “Waiting for what?” she asked. “We waited for a promise of a new day from five superintendents,” to turn around the public schools in the 18 years the charter school has been operating. Pennotti maintained her school’s standardized test scores far exceed the public schools’ and “for the sake of the children we have to move forward.”Rumage, who has been in the district for less than two years, fired back that Pennotti and others have mischaracterized the public school students’ achievements. “The big issue here is that people don’t know the full story,” and the strides the public district has been making over the years.The public school disproportionately faces more challenges than the charter school population. Ninety percent of the 1,410 students at the middle and primary schools qualify for (mostly) free and reduced cost lunch, a traditional measure of family income levels. The population also includes 33 percent of students who are limited English language proficient.By contrast, 52 percent of charter school are white (as compared to the 8 percent in the public schools), with a 4 percent population that is limited English-language proficient. The charter school population is 34 percent Hispanic; the public school population is 78 percent Hispanic. The number of charter school students who qualify for the free and reduced cost lunch is currently 38 percent.And some sources indicate that the per pupil funding results in the charter school receiving $2,000 more per student, per year.Julia Sass Rubin, an associate professor at Rutgers University’s Edward J. Bloustein School of Planning and Public Policy, and an adjunct professor at Princeton University, has been studying Red Bank and its Charter School as part of her research on state funding of charter schools. Her analysis indicates the charter school has yet to live up to its potential even with its additional resources and continues to contribute to a segregated school district. “The data is pretty straightforward,” she said. “The district is underfunded relative to the charter school, under the current formula.”And when factoring in other variables, the larger percent of special needs students, among others, the divide is closer to $5,000 more per charter school student. And taking all of that into consideration, Rubin said, “if you look at all of those considerations, the charter school is really underperforming,” she said.In her final analysis, this expansion, “would either be devastating for the district or devastating for the taxpayers.”It should be noted Rubin has her detractors. In response to a report on charter school funding, enrollment and demographics she did with a doctoral candidate Mark Weber last year, the New Jersey Charter School Association, a charter school advocacy group, took Rubin to task. The association accused Rubin of having a personal agenda against charter schools.Rubin, this week denied that, offering, “Am I pro-public schools? Absolutely. But I’m not anti-charter school,” noting her daughter had attended a charter school for couple of years and Rubin had served on a nonprofit board that provided charter school facility funding.Rubin planned on providing her research to local educational and elected officials on Friday.This debate has spilled over into the political arena, as well. Mayor Pasquale Menna at this year’s annual reorganization meeting called it “The elephant in the room.”While the borough council has no formal say in the matter or decision, Menna plans to form a “blue ribbon committee,” of objective educational and financial professionals to evaluate the plan’s impact. Their report will be submitted to the DOE for consideration.In addition, on Wednesday evening the borough council was expected to vote on a nonbinding resolution asking the charter school to delay any actions until more information can be collected.Council sources said there was unanimous and bipartisan support for the resolution.
In observance of Occupational Safety and Health Month 2016, Unicomer Guyana Inc commonly known asJunior Minister of Health Dr Karen Cummings and Deputy Mayor Sherod Duncan, examine a booth at the health fair and expoCourts, on Monday inaugurated its first health fair and expo in front of its Main Street office.Hosted with the intent of disseminating information to the public on safer health practices, the expo featured a number of booths from varying health organisations.This newly introduced initiative is one of the company’s strategies of giving back to Guyanese in a different way than its usual retailing business.Country Manager of Unicomer Guyana, Clyde de Hass during his remarks at the opening said this is just the company exhibiting its social responsibility to the community by means of spreading awareness of healthier living.He said that for two days the health fair and expo will serve as an easier way of educating persons on healthy practices, and hopefully this information will continue to spread throughout the country.Present at the expo was newly elected Deputy Mayor of Georgetown Sherod Duncan, who lauded the initiative by the company which adds to the already long list of other activities that the company over the years have been embarking on.Duncan said over the years the company has been able to move to higher heights, but in all, giving back to the communities continue to be high on its agenda as it fulfils its corporate responsibility.Since its existence the deputy mayor said, Courts has been able to effectively work towards promoting a healthier city through its many cleanup campaigns which shows its dedication to the country’s development.For this reason, Duncan pledged the Mayor and City Council’s support for initiatives such as these which benefit the general public.Meanwhile, Minister within the Ministry of Public Health Dr Karen Cummings also congratulated the company on its first health fair which she outlined will serve a significant purpose for the Guyanese populace.She said this initiative would aid the ministry in achieving its goal of having a Guyana which is filled with healthy persons, who in turn will be more productive.Cummings said the aim of government is to reduce the risk factors that contribute to unhealthy living, and with more initiatives like these Guyana will be on its way to reaping tangible benefits.She therefore encouraged other companies to emulate Unicomer and join the body of persons who want to see their country develop in every possible way.The minister said government and more specifically the Ministry of Public Health is ready to work with any company to combat diseases, viruses and any other medical illness that plague the country’s population.The speakers urged all Guyanese to take full advantage of what the fair is offering since it is only on for two days.Booths at the expo will be engaging the public in discussions on how they can care for their health, as well as offering free tests for those visiting.
selena larson The Dos and Don’ts of Brand Awareness Videos YouTube announced a new way of filtering out annoying comments on videos. Starting this week, YouTube comments will be powered by Google+, Google’s social network.The video site is notorious for users who down-vote videos en masse or post vicious replies, so YouTube is taking action to provide higher-quality comments and conversations.YouTube declares that it’s making comments better by integrating Google+. It will prioritize comments from recognizable profiles, like the video creator or friends. Posted comments can be shared privately or in users’ Google+ circles, and additional moderating tools will give video creators the ability to block phrases or auto-approve comments. “The grand idea is to try and turn these one-off comments into conversations that you really care about,” said Matt McLernon, a spokesperson for YouTube.But There’s Another Agenda HereWhile this seems like an effort by YouTube to improve the user experience, it is also a thinly veiled attempt by Google to bring Google+ services to the mainstream. Google has already integrated its social network in most of its products with the hopes of increasing engagement, provoking annoyance among some users. YouTube will be one of Google’s largest platforms to force its users to sign up for a Google+ account.Google+ may be the web’s second-largest social network behind Facebook, but that could be due to the fact that almost everyone with a Gmail account has a Google+ account, too. Whether they’re using them or not is another story.YouTube users who don’t already have a Google+ account will have to sign up for one using a Gmail address in order to participate in page discussions and, eventually, to comment on videos.YouTube said that users can register with either a Google+ profile or page so they can still use anonymous usernames. “On the Google+ side, you enter as much information as you like,” McLernon said. “On the YouTube side you can use a Plus page, so if you want to be awesomeperson5000, you can do that.” YouTube claims that the majority of YouTube commenters are already Google+ users, so many people might not even notice a difference. But with over one billion monthly unique users, there is bound to be a significant amount of people that registered with alternative email addresses. The company is risking a user revolt by mandating all commenters be Google+ users, as many people are already unhappy that the service is being forced on them. YouTube will begin rolling out the changes on channel pages today, with the exclusive Google+ commenting and linking system due globally later this year.Image via BrianDHawkins on Flickr Related Posts Tags:#Google#YouTube Guide to Performing Bulk Email Verification Facebook is Becoming Less Personal and More Pro… A Comprehensive Guide to a Content Audit
Violence erupted again in the Darjeeling hills on Saturday after two persons were killed, allegedly in firing by police and security forces. The Army was redeployed to control the situation, which turned volatile as pro-Gorkhaland supporters clashed with the police in Darjeeling town and adjoining areas. Tension gripped the hills after the death of Tashi Bhutia, a Gorkha National Liberation Front supporter, at Sonada. GNLF spokespers- on Neeraj Zimba said Bhutia was shot dead by security forces on Friday night. The police, however, said they did not have any report of firing. “We don’t have any report of police firing as of now. We are looking into the incident. We can give you details later,” a police officer said. Clashes erupted as the procession carrying Bhutia’s body turned violent and protesters attacked a police outpost at Sonada. A pitched battle ensued between the protesters and police. The protesters also set ablaze the Sonada station of the heritage Darjeeling Himalayan Railway. The violence soon spread to Darjeeling town with clashes at Chowk Bazar. Police resorted to tear gas shelling to disperse the mob, which allegedly tried to attack the office of Deputy Superintendent of Police. A second youth later succumbed to bullet injuries sustained during the violence. He is yet to be identified but is thought to be a resident of Singhamari. Clashes were also reported from Kalimpong where protesters set on fire property of the State Forest Department.Two columns of the Army, one at Sonada and the other in Darjeeling town, were deployed to control the situation. “One accident has happened at Sonada. This is because they attacked the police.. We will have to look into who is responsible,” Chief Minister Mamata Banerjee said at the State Secretariat. Urging pro-Gorkhaland supporters to shun violence, Ms. Banerjee said she was ready to hold meetings with political parties in the hills in the next 10-15 days. “I am asking the administration and the people to exercise restraint,” she said.She asked protesters to allow the government to send food and other supplies to the hills.
Serena Williams of the United States celebrates winning her women’s singles quarterfinals match against Italy’s Camila Giorgi, at the Wimbledon Tennis Championships, in London, Tuesday July 10, 2018. (AP Photo/Kirsty Wigglesworth)LONDON (AP) — Serena Williams came up with a comeback to reach the semifinals at Wimbledon, then walked off Centre Court with her right index finger aloft.Yes, no matter what the rankings or seedings say, she still looks as if she’s capable of playing like someone who’s No. 1.Williams moved closer to her eighth title at the All England Club and 24th Grand Slam trophy overall — but first since missing more than a year while having a baby — by beating 52nd-ranked Camila Giorgi of Italy 3-6, 6-3, 6-4 in the quarterfinals Tuesday.“This is only my fourth tournament back, so I don’t feel pressure. I don’t feel I have to win this; I don’t feel I have to lose this,” Williams said. “I’m just here just to be here and to prove that I’m back. And I feel like I’m back. I still have a long way to go to be where I was.”Williams was seeded 25th by the All England Club, a nod to all of her past success at the grass-court major, including titles the last two times she entered it, in 2015 and 2016. She missed Wimbledon a year ago because she was pregnant, and she went about 16 months between Grand Slam tournaments, so her ranking is just outside the top 180.That is going to change now.Next up for the 36-year-old American is a match against No. 13 seed Julia Goerges of Germany, a 3-6, 7-5, 6-1 winner against No. 20 Kiki Bertens of the Netherlands.This is all brand new for Goerges, who had never even been to a Grand Slam quarterfinal before this week. Plus, at Wimbledon in particular, she lost in the first round each of the past five years.Williams is 3-0 against Goerges, winning in straight sets each time.“Every match starts from zero,” Goerges said. “Everybody has the same chances to win that match, and I’m looking forward to it.”After their most recent meeting, in the French Open’s third round last month, Williams pulled out of that tournament, citing a chest muscle injury that made it too painful to serve.After going a couple of weeks without hitting a serve, Williams has regained her ability with that stroke nicely at Wimbledon.She hit one at 122 mph against Giorgi, delivered six of her seven aces in the final set, and won 44 of the last 54 points she served.It was the first time she’d needed to erase a real deficit this fortnight: Williams hadn’t dropped a set until facing Giorgi, who was in her first Grand Slam quarterfinal.“After the first set, I was like, ‘All right, let’s go three sets.’ And that’s kind of what I thought. … ‘I’ll just keep fighting,’” Williams said.The other semifinal Thursday will be No. 11 seed Angelique Kerber of Germany vs. No. 12 Jelena Ostapenko of Latvia.Kerber is a former No. 1 who owns two Grand Slam titles and was the runner-up to Williams at the All England Club two years ago. Ostapenko won last year’s French Open.Kerber needed seven match points to close out No. 14 Daria Kasatkina of Russia 6-3, 7-5 at Centre Court, while Ostapenko defeated 2014 Australian Open runner-up Dominika Cibulkova of Slovakia 7-5, 6-4 on a windy No. 1 Court.Kerber took advantage of Kasatkina’s 31 unforced errors, including seven double-faults, but took a while to end things. Kerber served for the victory at 5-4 in the second set, but got broken. When she served for it a second time, she needed to navigate a 16-point game that included five deuces and all of those match points, until forcing a forehand error on the last.Ostapenko played her usual aggressive style, compiling a 33-6 edge in winners.In the last men’s quarterfinal, which was suspended because of darkness after the third set Monday night, 2009 U.S. Open champion Juan Martin del Potro defeated Gilles Simon of France 7-6 (1), 7-6 (5), 5-7, 7-6 (5).Del Potro held four match points while serving for the victory at 5-4 in the fourth set, but had to wait until the last tiebreaker to advance in 4 hours, 24 minutes, making it the longest men’s singles match of the tournament.On Wednesday, del Potro faces Rafael Nadal.

(PhysOrg.com) — While most people are familiar with the fact that many species of female spiders eat their male counterparts, new research findings published in the Biological Journal of the Linnean Society show how biologists have found a species with an apparent role reversal with the male eating the female. Mosquitoes supply spider with blood © 2010 PhysOrg.com More information: AISENBERG, A., COSTA, F. G. and GONZÁLEZ, M. (2011), Male sexual cannibalism in a sand-dwelling wolf spider with sex role reversal. Biological Journal of the Linnean Society, 102: no. doi: 10.1111/j.1095-8312.2011.01631.x Located in Uruguay, Dr. Anita Aisenberg and the team of biologists from the Clemente Estable Institute of Biological Research have been studying the Allocosa brasiliensis. This nocturnal wolf spider is found on South America’s Atlantic Ocean coast and within the riverbank sand dunes. The study of these spiders began as they are an indicator of the coastal habitats health.However, during this study, they observed a male spider eating a female spider and set out to determine if this behavior was normal for the species as it has never been observed before in any other species. Where female spiders are usually larger and the dominant of the two, the researchers have found that with the Allocosa brasiliensis, the male has a traditional role reversal.The male spiders were observed waiting in their burrows for the females searching for mates. From what was observed by the researchers, the male spiders tended to mate with the younger, more productive virgin female spiders. The older, less productive female spiders were instead eaten by the male spider. It appears that the choice of whether to eat or mate with a female spider is based on the higher reproductive possibility.The environment where the Allococa brasiliensis live is one of instability for the spiders and the prey is unpredictable. In addition to this the area offers extreme temperatures and strong winds. Dr. Aisenberg believes that this unstable environment may have been a contributing factor to the apparent role reversal and unusual sexual behavior.
