Christopher George relieved Capt. Jeffrey Bierley and assumed the duties and responsibilities of commanding officer for the Seawolf crew.Bierley assumed command of the Seawolf crew in February of 2014. During his leadership, the crew completed a six-month deployment, where they completed important national and anti-submarine warfare tasking, theater security cooperation port visits, participated in sea exercises with partner nations, and surfaced from under the ice twice.They conducted initial testing for a prototype research and development system designed to enhance the ocean sensing capability of fast-attack submarines. The crew also received the SUBDEVRON 5 Battle Efficiency “E” award for both 2014 and 2015.“USS Seawolf has a deserved reputation as the most capable submarine ever constructed,” said George. “It is a truly humbling and daunting responsibility to command such a ship and follow in Capt. Bierley’s footsteps.”Seawolf, commissioned July 19, 1997, is the first of the Navy’s three Seawolf-class submarines. USS Connecticut and USS Seawolf are based at Bremerton, Washington while the USS Jimmy Carter (SSN 23), which is 100 foot longer than its two counterparts, is based at Naval Base Kitsap-Bangor.Originally intended as a class of 29 submarines, the end of the Cold War and budget constraints led to a restructuring of the class to three submarines. The Seawolf is significantly quieter than any Los Angeles class submarine, faster, has more torpedoes tubes and can carry more weapons – up to 50 torpedoes or missiles, or 100 mines.USS Jimmy Carter is additionally fitted with an extra section called the multi-mission platform which serves to launch and recover ROVs or Navy Seal forces.last_img read more

first_img Class of 2024 yield drops marginally Chan School’s Healthy Buildings Program leader expects biggest challenge will be compliance by all Pandemic threatens to veer out of control in U.S., public health experts say I think the other way to think about this is to look at student work when you can. And that’s just hard to do with the big state colleges where they’re spending about six or seven minutes per application because they have 60,000 applications. But again, if a third-party organization took that on it would be possible to do with that organization.Then there are things like the Mastery Transcript Consortium. They’re trying to shift away from traditional grades and have assessments that are based on the mastery of certain skills and knowledge. I think more and more high schools are going to start to turn to those kinds of things. And my sense is that more colleges will start to use the Mastery Transcript as an alternative to grades.GAZETTE: What are “soft skills” and how do they play a role in the college application process?WEISSBOURD: I am not a big fan of the term because these are really not soft skills. There’s quite a lot of data that things like self-awareness, curiosity, diligence, perspective-taking, social awareness, collaborative skills, are all really important for college and career success. (Interpersonal, and social emotional, and ethical skills, and being a responsible member of your community and acting with integrity are also connected to work success.) So these are things that are really important to measure if you’re a college and you’re trying to figure out whether a student will be successful at your school. Many of these skills are tied to engagement in college and engagement in college is a strong predictor of work success. So these are important for schools to measure, and colleges really need to pilot a lot of different kinds of measures of these different skills and do a good job defining them and defining what constitutes evidence of them in an application. They need to think about different kinds of assessments, whether those are written assessments or brief interviews, or video prompts, a variety of things. And again, I think this is a year to experiment with a lot of these things.GAZETTE: Are there other kinds of experiments that you think might be helpful in identifying these kinds of traits?WEISSBOURD: There may be different types of recommendation forms and additional recommenders that will help colleges find out more about these traits. Maybe you reach out to other recommenders in addition to teachers, including peers or sports coaches, so you are getting multiple recommendations or just rating sheets from different people and looking at where there’s convergence on certain traits.Part of the problem with recommendations is that they tend to be inflated. People rate things highly on every measure. But what if you said to recommenders, “Name the four characteristics that most describe this person,” so you have to choose between different characteristics? And then you look at which of those characteristics turns out to be most predictive of success at your college over time? So there are a lot of different ways to think about this. Another idea is to come up with an alternative to the SAT/ACT that doesn’t advantage privileged kids in the same way. I’m not advocating for any particular alternative. I’m just advocating for trying and seeing what happens. My guess is that we can do this in ways that are more just and more accurate and create less stress on students. Healthy buildings expert outlines recommendations for school reopenings The Daily Gazette Sign up for daily emails to get the latest Harvard news.center_img COVID-19 fears leave some students opting to defer until 2025 With COVID now in more isolated spaces, there’s greater potential for it to take off Applying to college is stress-filled during the best of times. But in the age of coronavirus, the annual effort by high school students to combine their grades, recommendations, test scores, extracurricular activities, and personal essays into standout applications has sent anxiety levels soaring. Some high schools have gone to pass/fail grading, sparking fears about the fallout for GPAs; many extracurriculars have been canceled; and dozens of colleges, including Harvard, have waived standardized tests as a requirement for Class of 2025 applicants, raising concerns among those who feel particularly confident about their test-taking skills. Last week, the Harvard Graduate School of Education released a statement from more than 300 college admissions deans, including William R. Fitzsimmons, Harvard College’s dean of admissions and financial aid, that aims to ease fears by clarifying what the administrators value in applicants during such uncertain times. The Gazette spoke with Richard Weissbourd, faculty director for Making Caring Common’s Turning the Tide, an HGSE initiative focused on underscoring what is important in college admissions, about the statement and how admissions might permanently change in the wake of the pandemic.Q&ARichard WeissbourdGAZETTE: Why did you feel it was important to release this statement from the deans?WEISSBOURD: There are several reasons, including the misinformation swirling out there. A lot of people have anxieties and questions because it’s such an uncertain time with the SAT and ACT being canceled until the fall, many schools going pass-fail, and other changes. So, it was partly to respond to that anxiety and the deans feeling that they could post things on their websites and communicate with parents individually, but that if they spoke collectively, it might break through a lot of the misinformation and provide reassurance and clarity to students and parents.Two other things that we were very interested in, and something we work a lot on with admissions deans at Making Caring Common, are equity and assessing context. It’s really important to understand the challenges that kids are facing, to acknowledge that those challenges have suddenly become much bigger, and that you can’t really assess kids fairly unless you understand that context. For example, if a kid is taking care of a sick relative 20 hours a week or supervising a younger sibling 20 hours a week and they’re just getting to their schoolwork and getting B’s and C’s, that’s really impressive and that’s often not captured in an application. Right now kids are home all the time, they may not have a quiet place to read, and they may not have access to the internet. These are the kinds of additional challenges that have been piled on. As a matter of equity, I think deans need to assess and take into account those challenges. The statement encourages students to report these challenges and obstacles and reassures students that what they write will be confidential and will only lead to a more positive review of their applications. A lot of students don’t think to report obstacles in their lives for a variety of reasons, and so we felt encouraging them is very important.The deans also really authentically want to communicate the message that self-care is important, that students should be gentle with themselves, and that during this difficult time, the goal is not doing extraordinary service of some kind. They want to make it clear that helping address issues with COVID-19 or working for racial justice or registering people to vote are clearly valuable ways to spend one’s time for those who are able. But they don’t want to create a pandemic service Olympics where students are seeking out high-profile opportunities to bolster their resumes. They also want students to know they will primarily base the evaluation of their academic achievements on their work before and after the pandemic.GAZETTE: Do you think this is a moment for admissions offices to consider reforming the college application process?WEISSBOURD: I hope so. I hope this is a laboratory moment, a moment where people really try different things and see what the outcome is of trying those different things. A silver lining in this pandemic is that it has created opportunities to rethink and reimagine many things, and college admissions is one of them. A lot of colleges are not going to have standardized test results for many students. And so they’re going to have to figure out alternative forms of assessment or look more deeply into the data that they do have. And what if it turns out that having the SAT or ACT didn’t matter, that they’re still admitting pools of students who are just as engaged and doing just as well without students having to experience the stress and stigma of the high-stakes testing? I think it’s an opportunity to try forms of assessment that don’t clearly favor those with privilege. It’s also an opportunity for admission offices that can do it to try things like short online interviews, or to have students respond to brief prompts on video. It would also be great if an organization emerged that could evaluate actual student work.,GAZETTE: When you say student work, what do you mean exactly?WEISSBOURD: What I mean is a high school student’s sample of their writing or a piece of their music or art. There’s a lot of focus these days on performance assessment, meaning that what high school students should be sharing with colleges are actual examples of their work. The problem is that a lot of colleges don’t have the capacity to evaluate that work. So if there was a third party who could evaluate that material and give the information to colleges, that would be a great thing. And some of the deans are calling for that. And I think that could be really important in the era of coronavirus when information about grades is going to be compromised. It’s hard to evaluate grades when there’s been such unevenness in how schools have responded to this pandemic. I think the college admissions deans are going to have to get really creative about thinking about other ways to do this. And those other ways might turn out to be better in the end.GAZETTE: In the wake of the pandemic, there have been some problems administering the SAT, and more and more colleges are choosing to make the test optional. Can you talk a little bit more about the SAT and its advantages and disadvantages?WEISSBOURD: The SAT appears to be more useful in predicting success at some colleges than others. For example, at MIT your math score may be a good predictor of success. At other colleges, it looks like the SAT/ACT are really not helpful. I do think there’s a real danger that if you get rid of the SAT/ACT, affluent parents will just find other ways to game the system that won’t do anything to make the playing field any more level. They might even make it less level. You get rid of the SAT/ACT and the attention turns to the number of AP courses you have, or the number of high-profile awards you received, or the number of leadership positions you hold or the number of community-service organizations you started. That’s what you don’t want to have happen because wealthy families will have lots of advantages. They can pay for expensive tutors, and they’ll have greater access to these opportunities for their kids. So without standardized tests, I think it is on colleges to really develop forms of assessment that are more fair and equitable and less vulnerable to that kind of gaming. And that’s a hard thing to do. But I think this is the year to really think hard about how to do that.GAZETTE: What other ways can college administrators assess student achievement?WEISSBOURD: One is by understanding grades in context and weighting them accordingly. Many kids have serious family responsibilities or are working to support their families many hours a week. That’s part of the evaluation of the student and it’s weighted. You look at a B from that student differently than you would look at a B from a student who doesn’t have those kinds of responsibilities. “[The deans] don’t want to create a pandemic service Olympics where students are seeking out high-profile opportunities to bolster their resumes.” Relatedlast_img read more

first_img AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREUCLA alum Kenny Clark signs four-year contract extension with PackersHis presence back on the floor was welcome, although Coach Luke Walton said the scrimmage was “sloppy” and that Ball committed “way too many turnovers.”“Lonzo showed why he’s going to be really good,” Walton said. “But he also showed that he’s been out for a couple weeks with some of the turnovers he had.”Ball sighed in agreement, saying he was “a little rusty.”“I had a lot of turnovers today,” he said, “but, like I said, as long as I’m ready for Thursday that’s all that matters.”Ball has not played since Oct. 2, when he suffered what was then termed a mild left ankle sprain. He missed the final four exhibition games, and did not participate in practices until Oct. 12. Monday was the first day he scrimmaged. EL SEGUNDO — The lights inside Staples Center will go dark, music will blast, the lineup will be introduced.  And when the lights come up on Thursday night, Lonzo Ball will be on the court, poised to make his debut in the Lakers’ season opener.“I’m playing for sure,” Ball said.The Lakers rookie put to rest any concern that the sprained ankle that forced him to miss all but six quarters of the preseason would affect his availability when the regular season begins Thursday against the Clippers.Ball was on the floor for the Lakers’ scrimmages on Monday, leading the first team to a victory, bringing his overall record, he said, to “a lot of wins to very little losses.” The former UCLA and Chino Hills High star cleared up one mystery on Monday. When asked which shoes he plans to wear once the regular season arrives he said, “We’ll see. I’ll probably play in mine.”That would put to rest the parlor game that first sprung up in Summer League, and continued into his two preseason appearances, when Ball made waves by alternating between his signature Big Baller Brand ZO2s and other companies’ sneakers.Despite the fact Ball is coming off a significant ankle sprain, the Lakers have no plans to intervene in his footwear decisions, Walton said.“As long as all the shoes are strong enough to support him he’s going to wear what he wants,” Walton said. “Guys used to play in Chuck Taylors and they played entire NBA careers. Unless there is something wrong with the actual way they are made, the stitching and they just rip out, then he should be able to wear what shoe he wants.”THE MOST DENG-EROUS GAMEBall’s team welcomed a surprising face for at least a portion of Monday’s scrimmage: Luol Deng, relegated to a cheerleading role for most of the preseason, played with the starting unit.The Lakers will be without Kentavious Caldwell-Pope on Thursday. He was suspended in June for the first two games of the season after pleading guilty to operating a motor vehicle while intoxicated.Walton said he is considering five players to replace Caldwell-Pope for those two games and, yes, the possibilities include Deng.“Luol is one of the options,” Walton said, “but I wouldn’t say we’re leaning in any certain direction yet.”Walton said he has contemplated starting Corey Brewer and Jordan Clarkson, as well as rookies Josh Hart and Kyle Kuzma. Hart might be out of the mix, however, after he left practice Monday with a strained left Achilles tendon.Deng averaged 7.6 points for the Lakers last season after signing a four-year, $72 million contract. He appeared in 56 games, including 49 starts.center_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more

first_imgDarnell Nurse, a defenseman, puts on a Edmonton Oilers hat after being chosen seventh overall in the first round of the NHL hockey draft, Sunday, June 30, 2013, in Newark, N.J. (AP Photo/Bill Kostroun) After picking first the last three years, the Edmonton Oilers took defenseman Darnell Nurse, of Saulte Ste. Marie in the OHL, with the seventh choice. Nurse is the nephew of former Philadelphia Eagles quarterback Donovan McNabb. McNabb posted a picture on Twitter of the two of them smiling together a couple of hours before the draft.McNabb was famously booed by Eagles fans in the 1999 draft and was hurt for years by the reaction. Nurse heard polite applause in Newark.“We’re even, because he went higher than me,” Nurse said, “but I didn’t get booed at my draft.”Jones, who lived in Colorado as a youth and seemed a perfect fit for the Avalanche, has ties to Tennessee, as well. Popeye Jones owns a house there, and there is still family throughout the state.“It’s a perfect spot for him,” Popeye Jones said, proudly. “He’ll be motivated there, and ready to go.”Nathan MacKinnon and Sidney Crosby now share more than a hometown.They’ve both been No. 1 picks in the NHL draft.The Colorado Avalanche made the 17-year-old MacKinnon the first pick of the draft on Sunday at the Prudential Center.The Avalanche won the draft lottery for the first time in team history and Joe Sakic, the man put in charge of Colorado’s rebuilding project, had made it clear that MacKinnon was going to be the top pick. He was the first player drafted No. 1 overall out of the Quebec Major Junior Hockey League since the Pittsburgh Penguins selected Crosby in 2005.MacKinnon and Crosby are both from Cole Harbour, Nova Scotia.“I love Sid. He’s my favorite player,” MacKinnon said. “I guess he’s still my favorite player. I don’t really know what to say now since I’m going to be in the same league as him. I don’t know if I should dislike him or not.”MacKinnon, a 6-foot, 182-pound center, said it all with a laugh. But he’s serious about making the big club this season with Colorado.“Hopefully, I can make the team and stick there,” MacKinnon said. “I feel like I can be a contributor next year.”MacKinnon is a solid two-way presence with strong hands and stick-handling and skating skills. He is considered a natural scorer and an excellent distributor. Sakic ended the guessing game in the final week when he said MacKinnon would be their pick.“They said it in the media but I didn’t really get my hopes up,” MacKinnon said. “I was definitely more nervous than I expected to be a couple of minutes before the draft.”He played for the Halifax Mooseheads and led them to the Memorial Cup championship. MacKinnon, who turns 18 on Sept. 1, was named tournament MVP after scoring 13 points.Next stop, Colorado? Seth Jones, a defenseman, pulls on a Nashville Predators sweater after being chosen 4th overall in the first round of the NHL hockey draft, Sunday, June 30, 2013, in Newark, N.J. (AP Photo/Bill Kostroun)by Dan Gelston and Ira PodellAP Sports WritersNEWARK, N.J. (AP) — Seth Jones won’t be going home to Colorado when his NHL career begins, however he will be heading to his famous father’s home state as a member of the Nashville Predators.After being rated No. 1 among North American skaters in pre-draft rankings, Jones was bypassed by Colorado, Florida and Tampa Bay before being chosen by the Predators at No. 4.The NHL had two Black players picked in the top seven with Jones at No.4 and Donovan McNabb’s nephew Darnell Nurse going to Edmonton at No. 7.The son of former NBA player Popeye Jones seemed happy in his bright yellow Nashville jersey, and will be able to learn about playing NHL defense from new teammate Shea Weber.“I’d be lying if I said I wasn’t thinking about going to those teams, but at the same time I’m excited to be a Predator, and obviously Shea Weber is there,” he said Sunday about slipping a few spots. “He’s a great player, and they have a lot of other great players, and I’m happy to be a part of the organization.”Popeye Jones is friends with one of the Predators scouts, and he said he was told that his son wouldn’t fall past Nashville at No. 4.“I know he was probably sitting up there thinking, ‘Oh wow’ because somebody said you may go one, you may go two,” he said. “When I got drafted in ’92, I didn’t get to come to the draft. I was just glad to be drafted. I knew how nerve-racking it was watching it at home when I went 41. I am sure it was nerve-racking, but I’m sure he tried to stay calm and cool to see where he was going to go.”Now Seth Jones has something else to prove, beyond the usual drive draft picks have to show that they belong in the NHL.“I think professional athletes or athletes in general are always looking for something to motivate them because there is always going to be dog days where you may not want to lift or do extra crunches,” Popeye Jones said. “But you will look at this and say, ‘I got drafted fourth. Maybe I need to get to the weight room again and try to prove guys wrong that I should’ve went first.’“You are also looking for that extra motivation.”So now Popeye Jones, drafted by the NBA’s Houston Rockets in 1992 and traded to Dallas, knows what NHL team he will be throwing his support to.“There is no disappointment in going to Nashville. It is such a great franchise,” he said. “It is my home state. I’ve got to get my Preds hat.”last_img read more

first_imgBy Elizabeth Wulfhorst “There’s still so much left for me to learn and this is a time to be amplifying Black and indigenous, people of color,” she said. “All I can say is that for white people, now is the time to listen, not speak. Support, not direct. And Black lives always have and always will matter.” “It’s easier for us to find information in this age and the world is so issue-ridden that we all have causes we care about,” she said. At a June 7 protest, Nupol Kiazolu, 19, the president of BLM Greater New York, said, “Young people have been carrying every single movement we’ve seen across the world, so it’s time for adults to step aside and uplift us. We are not just the future. We are the present.”  A movement that began in 2013 after the murder of a young Black man, Trayvon Martin, resurged this spring with the killing of yet another Black man, George Floyd. The Black Lives Matter (BLM) movement has grown since video in May showed a white Minnesota police officer kneeling on Floyd’s neck for almost nine minutes. Spurred by the Black community, other people of color and allies, the movement has also found a large number of supporters in Generation Z, young people approximately 23 and under, born after 1996. In 14 years of schooling, she said there has only been one Black teacher at a school she attended and she was never in their classroom. “Representation is so, so important, especially to young people,” said Efobi. “We need to be able to see people like us. It helps us be able to realize our dreams. There needs to be more diversity in teaching staff.” Amber Tanzi, 21, from Middletown, has also attended protests, and “donated, signed petitions, called offices, sent emails, done as much as I can to do my part,” she said. She thinks young people are socially aware because they use the internet to form connections with people across the world, expanding relationships beyond their hometowns, more so than prior generations could at her age. Efobi also thinks Gen Zers are more open-minded than their predecessors. She also feels the United States history curriculum in schools is lacking. “We need to learn about the Civil Rights movement and Black advocacy beyond Martin Luther King and Rosa Parks,” said Efobi. As many young people do, she began educating herself about the gaps in her studies, parts of history she feels should be taught to all students. “I believe that us not learning about Hispanic, Latinx, Asian, Polynesian, African, Caribbean and LGBT communities is a big contributor to today’s bigotry,” she explained. “And we’re saying ‘Enough is enough.’ If the people in charge don’t seem to care enough, then we must take matters into our own hands.” Members of Gen Z are “digital natives,” according to the Pew Research Center, those who grew up with little or no memory of the pre-smartphone era. And they have used their knowledge of the digital world and social media to communicate about BLM and support protests in cities around the country and the world. They use the internet to their advantage – to publicize, educate and share stories on platforms like Twitter, Instagram and TikTok. As of July 7, #BlackLivesMatter was used in more than 22 million posts on Instagram, where users share their stories, educational resources, ways to donate and links to petitions. Local and state governments across the country removed statues, monuments and flags that memorialized historical racism after protests advocated for their removal. Organizations and companies have also taken a stand, firing and removing individuals from positions of power who have exploited or treated BIPOC (Black, Indigenous, People of Color) employees unjustly. Presidents and CEOs resigned because of prior racist acts and words. Corporations like Disney World and Quaker Oats, major sports organizations, television studios and even musicians have abandoned racially charged products, shows and names.  At protests across the country, like this one last month in Red Bank, young people have been instrumental in the Black Lives Matter movement. Photo by Patrick Olivero Calls to action from Efobi, Tanzi, their peers and others have sparked some change. Though police reform at a national level is still lacking, reform is beginning at local and state levels. “No-knock” warrants have been suspended in many police departments, as have chokeholds, and officers have been fired – and some even charged – for their part in unjust actions against Black Americans.  But systemic racism is most concerning to members of Gen Z and something both Tanzi and Efobi feel they have a chance of combatting and even overcoming. One way to make that happen, according to Efobi, is through education. “I’m a Black girl and I never saw much diversity around me until my sophomore year of high school. That was reflected in the curriculum and classroom conversations,” she said. She experienced firsthand the effects of institutional racism when she tried to explain to a middle school history teacher why saying “all lives matter” was disrespectful. Efobi told her, “You wouldn’t walk into a breast cancer treatment center and announce that there are other types of cancer, nor would you walk into a funeral and say that you’ve lost someone, too.” The teacher told the other students Efobi didn’t know what she was talking about, Efobi said. Many of those young people live in the Two River area, like Chika Efobi, 17, a first-generation Nigerian-American from Long Branch who uses Instagram to help secure justice for victims of police brutality. She shares “useful information that I come across that will help people understand the systemic racism that’s been embedded in our lifestyles,” Efobi said. As a white person, Tanzi feels now is a time for reflection and allyship, not stealing the spotlight from those who truly need it. She said she will continue to educate herself and hopes others do the same. Even though she isn’t BIPOC, Tanzi understands Efobi’s experiences with lack of representation. “I am a Jewish, bisexual woman who grew up in a town that didn’t have many resources for those things,” Tanzi said. She believes these facets of her identity allowed her “to not only empathize,” but also “actively fight alongside any group that needed help.” Efobi, who throws shot put for the Mater Dei Prep track and field team and plans to pursue a career as a physical therapist for athletes, has attended two Black Lives Matter protests so far. “I also make sure I have the hard conversations with my friends and peers which are absolutely necessary if we want a genuine change,” she said. “Thus far I’ve been fortunate enough to have friends who understand the movement.” Tanzi, who said she became socially active after the 2016 presidential election, agreed that access to information has spurred Gen Z’s involvement in the movement. “With a world of news, albeit both accurate or otherwise, right in front of us seemingly at all times, we’re potentially the most well-informed generation of young people to ever exist,” she said. Tanzi cited growing up with events like 9/11, the war in Afghanistan, the 2008 financial crisis and “so many school shootings with no intervention from our government” as the impetus for social activism. “We’re finally exposed to and can comprehend on our own all the cracks in the systems,” Tanzi said. The article originally appeared in the July 9 – 15, 2020 print edition of The Two River Times.last_img read more

first_imgPlants are not as stationary as one might think.  Parts of them, like seeds, can travel for miles.  One good example is the maple seed.  Its little helicopter seeds can catch an updraft and fly a long distance from the tree.  Now, engineers at University of Maryland have imitated its physics and designed a radio-controlled mono-copter that can sustain stable flight for hours.    “Winged seeds, or samaras, such as that of the maple tree are considered some of the most efficient passive flyers, and hence have been ogled by many engineers looking to build tiny flying devices,” reported Live Science, which posted a cool video of the robot version in action.  “Since the 1950s, researchers have been trying to create a stable, unmanned aerial vehicle that could mimic a maple seed’s flight,” reporter Jeanna Bryner continued.  “But their attempts have been unsuccessful, typically because of instability.”  The new device, with its wing that looks just like its natural counterpart, can take off from the ground or be dropped from a plane and then fly laterally in controlled flight.  If it loses power, it can spiral down to the ground unharmed.  Maple seeds either drop straight down while spinning, or spin down in large helical patterns.  Placed in the right thermal, the robo-maple could spin on free wind energy for hours.    This invention could become a cool toy some day (unfortunately, not ready for Christmas this year).  It makes an irritating buzzing noise, though, so parents might want to consider looking for a passive version that can be launched in a slingshot or something.  Because it can carry a small payload, including a video camera or transponder, engineers also envision applications for low-altitude satellites, surveillance, weather or fire monitoring, communications from the battlefield, search and rescue support, aerial mapping, and radio relays.  One thing it can’t do, though, is grow a tree.    Science Daily shows the device fitting in the palm of a hand.  PhysOrg also reported the story with three more videos.  Some other trees, like elms, ashes and sycamores, sport winged samaras like those on maples.  See the 06/16/2009 entry about the flying efficiency of samara propellers, and the 09/22/2008 entry about seed dispersal. Some kid some day is going to freak out the neighbors with fake UFO sightings.  One of the videos described this project as “Inspiration – Imitation – Invention – Evolution” but the evolution was the engineers’ intelligently-guided attempts to refine their imitation of nature.  So it was intelligent design science all the way.  This invention is a great achievement by the young engineers at University of Maryland.  It only took mankind 59 years to figure out how the maple seed does it.  Hopefully this project will create more interest in the design inherent in natural forms.They fly through the air with the greatest of ease,Inherent design in the young maple seeds;Their movements are graceful, to engineers please,Poor Darwin’s been purloined away.(Visited 19 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_img7 July 2008Fixed investment in and exports from KwaZulu-Natal province are set to increase with the completion of the R6.5-billion Dube Trade Port – the largest single government infrastructure investment in the province – to the north of Durban.“The catalytic impact of this project will not be confined to the growth node in the costal area north of Durban, but will reverberate across the entire province and position KwaZulu-Natal as a destination of choice for domestic and international tourists,” KwaZulu-Natal Premier Sibusiso Ndebele told delegates at the International Investment Council in San Lameer in May.The council, attended by President Thabo Mbeki, Deputy President Phumzile Mlambo-Ngcuka and Cabinet members, drew on the insights of distinguished international business leaders on how to meet the challenges of economic growth in South Africa.By the time of its completion ahead of the 2010 Fifa World Cup, the Dube Trade Port itself will have contributed an estimated R12.4-billion to the economy and created thousands of new jobs.According to statistics, the Durban port is the busiest port city on the African continent and ideally located to access the international shipping routes between East and West. It is also the largest of South Africa’s seven ports.It handles in excess of 31.4-million tons of cargo a year, with a value in excess of R100-billion per annum – approximately 65% of the value of all cargo going through South African ports.According to a report released by Quantec data, KwaZulu-Natal’s top export destinations in 2005 were the United States, Japan, India, the United Kingdom, the Netherlands and Germany.More than R3-billion has been set aside for investment in Durban port’s infrastructure since 2002 for various improvements that include the construction of cargo terminals, Ndebele said.The province’s second port – Richard’s Bay – is also South Africa’s premier bulk cargo handling port and is one of the fastest growing industrial areas in the province, and the centre of operations for South Africa’s aluminium industry.Trade gatewayNdebele further told delegates that the foreign private companies had invested over R27-billion in the province between 2000 and 2005, enabling provincial economic growth to rise from 1% in 1999 to 5.3% in 2005.Since then, he said, the province had seen further groundbreaking fixed direct investments, while nearly a third of South Africa’s manufactured exports were produced in the province.These include the R2.4-billion expansion of Toyota’s plant outside Durban, a new R2.5-billion plant by United Pulp in Richards Bay, a R2-billion expansion at Sappi Saiccor at Umkomaas, and a R650-million investment by Tata in a steel plant in Richard’s Bay.In addition, an almost R20-billion investment is on the cards in the KwaZulu-Natal north coast for a “city within a city” project, modelled on the Dubai Palm complex in the Arab emirate.“These private investments are particularly encouraging for us and they are aligned to our national industrial policy,” said Ndebele. “KwaZulu-Natal has also recently undergone rapid industrialisation, thanks to its abundant water supply and labour resources.”Source: BuaNewslast_img read more

first_img4 March 2013South Africa’s Dawie van der Walt captured the biggest title of his career at the Copperleaf Golf and Country Estate outside Pretoria on Sunday when he was crowned the winner of the inaugural Tshwane Open.The final round of the event, co-sanctioned by the Sunshine and European Tours, began with a four-way tie for the lead, with Van der Walt, Africa Open champion Darren Fichardt, Charl Coetzee and Mark Tullo all on 16-under-par 200.Fichardt remained in the running, with a final round of three-under-par 69. Coetzee failed to mount a real challenge, posting a level-par 72, while Tullo’s game fell apart as he closed with a five-over 77. Van der Walt, meanwhile, fired an eagle on the 626-metre fourth, added four birdies and dropped just an single shot on the 10th, to finish with a five-under-par 67.‘Goal’“My goal was to shoot 10-under for the weekend, and my focus was reaching five-under for the round today. I’m just really happy that I played well and won, because you can play well and not win,” he said.Van der Walt, whose only previous wins had come on the satellite tours in the USA, was thrilled to finally make a breakthrough on home soil. He said: “You can only imagine what it’s like to win such a big one. I don’t know what I’ll do yet. The purses are a lot bigger on the European Tour, so I’ll have to rethink some things.”Van der Walt’s winner’s purse was €237 750 (R2.8-million).“You start doubting yourself,” he admitted, “and at 30 years old you start to wonder if you’re good enough, and this proves that I am.‘Fantastic’“I would have liked to win before 30, but I’ll definitely take this! Golf is a game where you don’t get a lot of chances to win, and to do it is fantastic.”Van der Walt identified the 12th hole, where he made a birdie, as being crucial to his victory. “It was a big turning point when I made that putt on 12, because I was just trying to make another birdie to get to five-under, and once it dropped I felt like I was in control,” he said.Fichardt began his final round superbly, slotting three birdies within the first five holes. He couldn’t find another one the rest of the way, though, and finished with 13 consecutive pars.Coetzee, like Fichardt, began well, with birdies on the second and third holes, but drops on the seventh, 13th and 14th, along with another birdie on the 10th led to a level-par round.Fell apartAfter rounds of 67, 66 and 67, Tullo had birdied 16 holes without a single drop, but his challenge fell apart over the final 18 holes. He improved to 18-under with birdies on the fourth and seventh, but then dropped a shot on the eighth.His inward nine then turned into a nightmare, with four bogeys and a double-bogey seeing him tumble to a 42 over the last nine holes and 77 for the round.Louis de Jager, who started the final round one shot off the pace, matched Fichardt with a 69 to finish in third place on 18-under-par 270.American Peter Uihlein, a former number one amateur in the world, claimed fourth place on 17-under 271.LEADERBOARD 267 Dawie van der Walt (RSA) (-21) 68, 65, 67, 67269 Darren Fichardt (RSA) (-19) 65, 71, 64, 69270 Louis de Jager (RSA) (-18) 71, 65, 65, 69271 Peter Uihlein (USA) (-17) 68, 66, 68, 69272 Bjorn Akesson (Swe) (-16) 66, 75, 66, 65272 Charl Coetzee (RSA) (-16) 67, 65, 68, 72272 Danny Willett (Eng) (-16) 68, 68, 70, 66273 Morten Orum Madsen (-15) 70, 67, 69, 67273 Graham van der Merwe (-15) 70, 66, 68, 69 Would you like to use this article in your publication or on your website?

first_img8 July 2013The Proteas’ 2013/14 home schedule, released by Cricket South Africa on Monday, includes highly anticipated test series against India and Australia, backed up by seven one-day and five T20 international matches.The Proteas, ranked number one in the world test ranking, will play three tests against both countries. India occupies second place in the ICC test rankings, while Australia is in fourth.The Indians last toured South Africa in 2006/07 and convincingly won the first test by 123 runs in Johannesburg, after dismissing the Proteas for only 84 in their first innings. South Africa, though, fought back to win the second test by 174 runs and clinched a 2-1 series win with a five-wicket victory in the third and deciding test.Philander’s debutAustralia last visit to South Africa was in the 2011/12 season, when they played only two tests. The Proteas scored a resounding eight-wicket victory in the first test, despite making only 96 in their first innings, after debutant Vernon Philander knocked over 5 for 15 in the Australians’ second innings of just 47 all out.Australia, however, shared the series’ spoils after a tense two-wicket win at The Wanderers in the second test.There will be seven one-day internationals played against India, which recently won the ICC Champions Trophy, and is ranked number one in the 50-overs format. South Africa is ranked fourth.Five T20 internationals are on the cards for the sixth-ranked Proteas, two of them against the world number three Indians and three against Australia, who are ranked one place below South Africa.Indian tourIndia’s tour kicks off on 18 November with a match against a South African Invitation XI in Potchefstoom. It runs through until the third test match, which will be played in Johannesburg from 15 to 19 January.Australia’s tour starts shortly after that on 5 February in the same manner as India’s tour, with a game against a South African Invitation XI at Senwes Park. It ends on 14 March with a T20 international at Centurion.Commenting on the schedule, CSA Acting CEO Naasei Appiah said on the CSA website: “It promises to be a wonderful summer of hotly contested international cricket.“India are the current undisputed champions of 50 overs cricket and it was not that long ago that they briefly held the number one ranking in test cricket as well.Sachin Tendulkar“The Indian players have always been very popular in South Africa and their maestro, Sachin Tendulkar, has currently played a world record 198 test matches. It would be wonderful for his 200th test match to be in front of a packed New Year’s crowd at Sahara Park Newlands.“The last time he played a test match there, his battle with Dale Steyn thrilled a global audience.”Looking at the series against Australia, Appiah said: “Any series between Australia and South Africa in any sporting code always promises a spectacle of note and a contest worthy of some of sport’s most famous moments. Australia will be battle-hardened after successive home and away Ashes series against England.“The three KFC T20 International matches at the end of the tour will provide perfect preparation for both sides for next year’s ICC World Twenty20.”Details of the ticket sales have not yet been announced.TOUR SCHEDULESIndia Tour 18 Nov: T20: India v SA Invitation XI, Potchefstroom21 Nov: 1st T20 International, Johannesburg (Day/Night)24 Nov: 2nd T20 International, Cape Town (Day)27 Nov: 1st ODI, Durban (Day/Night)30 Nov: 2nd ODI, Port Elizabeth (Day)3 Dec: 3rd ODI, East London (Day/Night)6 Dec: 4th ODI, Centurion (Day/Night)8 Dec: 5th ODI, Johannesburg (Day)12 Dec: 6th ODI, Bloemfontein (Day/Night)15 Dec: 7th ODI, Cape Town (Day)18-19 Dec: India v SA Invitation XI, Paarl22-23 Dec: India v SA Invitation XI, Pietermaritzburg26-30 Dec: 1st test, Durban2-6 Jan: 2nd test, Cape Town15-19 Jan: 3rd test, Johannesburg Australia Tour 5-8 Feb: Australia v SA Invitation XI, Potchefstroom12-16 Feb: 1st test, Centurion20-24 Feb: 2nd test match, Port Elizabeth1-5 Mar: 3rd test match, Cape Town9 Mar: 1st T20 International, Port Elizabeth (Day)12 Mar: 2nd T20 International, Durban (Day/Night)14 Mar: 3rd KFC T20 International, Centurion (Day/Night)last_img read more
