Maple to the Rescue

first_imgThe SWAT team surrounds the compound.  An officer tosses a maple seed into an open window and checks the readout on his computer.  The team bursts in and, surprising the terrorists, rescues the hostages safely.This scenario may become a reality, thanks to a new flying robot called Samarai, fashioned after the winged “samara” shape of the maple seed.  A high-energy video clip at Live Science tells the story of a tiny drone developed by Lockheed Martin for the military.  Engineers analyzed the shape of the seed’s wing and studied its flight dynamics.  Then they outfitted a plastic replica with a motor and a camera to create their miniature surveillance tool.Like a maple seed, Samarai has the advantage of very stable flight.  It can be launched from the floor, by a flick of the wrist, or from an elevated platform.  A remote control allows the operator to make it rise or turn in an any direction, or hover indefinitely.  (See “Introducing the Maple Copter,” 10/21/2009.)One problem was how to produce images on a spinning camera.  The team developed software that can take out the blur and stitch together the frames into a normal wide-angle motion picture, providing a stable 360° image.  This would allow our imaginary SWAT team to see inside the building to pinpoint the location of the terrorists and hostages.  The military would love to have these on the battlefield for reconnaissance.  Some day Samarias could be standard equipment for law enforcement, search and rescue, and other applications – thanks to the common, humble, ordinary maple seed.If it ever comes to the day when government snoops on citizens this way, be sure to have a strong fly swatter handy.  More likely, this will be one of the coolest toys for Christmas sometime.  Lawyers will undoubtedly find new opportunities to go after people spying on their neighbors.  Wise parents, though, will take their kids into the forest with their toy, let them enjoy it for awhile, then show them that the Creator designed it first.  The Creator even devised a way to stabilize an image from a moving platform (see 11/10/2006, 4/12/2005).

Education is offered as a solution

first_imgSakha Ingomso Lethu’s flagship programme aims to give access to quality education to those in rural South Africa. (Image: Wikipedia)Access to education is one of the defining differences between urban and rural youth – with opportunity far more easily available in cities than in the countryside.Sakha Ingomso Lethu, which means “building our future” in isiXhosa, aims to address this inequality. The NGO has a flagship programme, Sakha Ulutsha Lwethu, which means “we are building our youth”, to provide information and tools for rural and township youth to be able to access institutions of higher learning.It is the work of Simamkele Dlakavu, a social activist who has represented young people in various youth summits around the African continent and the world. In 2013, she was recognised by the Moremi Initiative, a Ghanaian NGO, as one of 28 of Africa’s Most Outstanding Emerging Women Leaders for 2013.Dlakavu holds a BA degree in international relations and political studies as well as an honours degree in political studies from the University of the Witwatersrand. In 2014, the Mail and Guardian newspaper named her one of South Africa’s Top 200 Young South Africans.“There are many reports that show the challenges facing rural and township youth attending school in these areas which include lack of infrastructure, lack of trained teachers, no facilities such as libraries or computer labs, amongst many well documented challenges,” Dlakavu wrote on SA Goodnews about the project.“What is often missing in such reports is the resilience and hunger that many of these youth have to get an education, which still remains one of the gateways to class mobility in South Africa.”Sakha embraces South Africa’s National Development Plan or Vision 2030, which seeks to improve the outcomes of the country’s rural development and education. In terms of the plan, South Africa is working to ensure people are not disadvantaged because they come from disadvantaged or rural areas.PARTNERSHIPSThe NGO held workshops in June 2015, during the school holidays, in Venda, in Limpopo. The province suffered serious educational challenges in the recent past when textbooks did not reach learners in time.“This year, in June/July, Sakha Ulutsha Lwethu partnered with Duke University and the Organisation for Tropical Studies, South Africa office (OTS) to run workshops for rural youth in HaMakuya, in Venda in Limpopo,” Dlakavu explained.“The workshops were focused on exposing the learners in HaMakuya to various study options for post-high school career options. The University of Cape Town, Wits University and the University of the Free State provided application forms, prospectuses and various other informational packages to help the students make the best choice proper fit career option.”Her group spoke to the learners about various funding options as many of them came from low income families. The area also had a very high unemployment rate, she explained, and many households were dependent on government grants and “piecemeal”, or temporary jobs.“OTS has been working in the HaMakuya area for a number of years now on various programmes such as the Global Health course run with Duke University, and as part of the programme a number of American (mostly) undergraduate students visit the area for about 10 days, three of which are spent on ‘homestay’ with the families in the area,” she said.“Yet the organisation realises the importance of not just taking from the community, but being able to give something back to the area and hence the partnership with Sakha was important.”Sakha held the workshops during the June school holidays but the turn out impressed Dlakavu. “Although it was still school holidays at the time of the workshops,” she said, “the students came out in numbers to listen and interact as some were in ‘winter school’, revising and already preparing for the final matric exams.“We heard the students want to pursue careers in engineering, medicine, the arts, law and many other careers. Yet, there were many other challenges such as uncertainty about where they would source funding for higher education, as well as uncertainty about the National Benchmark Tests some universities run.”last_img read more

Education Ministry Signs MOU With BAU University to Provide 107 Scholarships

first_imgThe Ministry of Education, Youth and Information and BAU International University in Washington DC  have partnered to provide 107 scholarships for student teachers to pursue undergraduate and graduate programmes at the institution under a three-year Memorandum of Understanding (MOU), valued at J$378.2 million (US$3 million).The MOU will additionally see the University hiring 200 Jamaican English language teachers for its network of schools located in the United States and several countries globally, for the 2018/19 academic year.The partnership resulted from discussions that Portfolio Minister, Senator the Hon. Ruel Reid, had with BAU University Board member, Paul Brunson, in Washington DC between 2016 and earlier this year.Jamaica’s Ambassador to the United States (US), Her Excellency Audrey Marks, and the Ministry’s newly appointed International Donor Consultant for the Jamaican Diaspora in the US, Gail Dunwell, who works closely with the National Education Trust, were also instrumental in initiating the partnership.Senator Reid, Mr. Brunson and President of The Mico University College, another pivotal partner in the engagement, Dr. Asburn Pinnock, signed the MOU on Thursday, November 29. This took place at The Mico’s Marescaux Road campus in Kingston.The Minister said the partnership was welcomed in light of the high cost of education, particularly at the tertiary level.Senator Reid said although the Ministry has been increasing funding for the sector, “there is always room for more support”, and in this regard lauded BAU University for partnering with the Government.“This MOU is the beginning of what we expect to be a very long and lasting positive relationship. We are certainly looking at how we can provide more scholarships to our tertiary students, (particularly) our student teachers, and other youth who want to pursue higher education,” the Minister said.For his part, Mr. Brunson said the initiative’s genesis dates back 10 years when he met his late grandfather who he learnt was Jamaican.Mr. Brunson said the knowledge of his heritage was the primary reason why he sought to see how best he could make a tangible and meaningful contribution to Jamaica.To this end, Mr. Brunson said he made representation to the University’s administration and successfully lobbied their support in March 2016 which resulted in the MOU’s crafting. “So for all these reasons and more, I am excited and I am proud. This, indeed, is only the beginning of this relationship,” he added.In his remarks, Dr. Pinnock, said the initiative was a “perfect fit” with the Government’s national focus for education.“I think this will go a far way in building our resources as we try to graduate more persons from tertiary education in Jamaica. A more educated nation is a more peaceful nation, a more prosperous nation (and) a bigger and better nation,” he added.BAU International University is a private, non-profit tertiary institution that offers undergraduate and graduate programmes in economics, international affairs, entrepreneurship, global affairs, and international law and economics.The Washington DC Campus is part of the BAU Global Network, spanning three continents, that has been providing higher education for over 15 years, with offices in Toronto, Canada; Berlin, Germany; and Hong Kong, among other locations.Its flagship campus is Bahcesehir University in Istanbul, Turkey, which has eight faculties, a school of languages, and two vocational schools.last_img read more

Heres the best laundry detergent you can buy right now

first_img Smart Home Enlarge ImageWe gathered a group of top-selling laundry detergent brands, then tested them to see which one cleans the best. Tyler Lizenby/CNET Laundry detergents are not all the same. It turns out that some brands pack more of a cleaning punch than others. That means some are better than others at lifting stains and purging fabric soiled by food, wine, grease and other common contaminants. And even the form of the detergent, liquid or pod, can affect how clean your laundry will get. After comparing the options from various retail outlets including Amazon, Walmart and Costco, we settled on nine detergent brands. We chose them since they’re top sellers at those sites, and because they’re all-purpose detergents meant for mainstream wash-day use. We intentionally did not include specialty products designed to primarily tackle baby clothes or delicate items.  Here’s how to buy your next washing machine 59 39 2:29 8 Photos Arm & Hammer Kirkland 40 All Liquid Now playing: Watch this: All Liquid Tide Pods The tech behind our washing machine testing (pictures) 53 42 52 48 reading • The best laundry detergent: 2019 review of pods and liquid detergents We then systematically put these detergents through our washing machine test lab. The process entailed weeks of washing, over 100 hours in all. In other terms, that’s more than 80 washing machine cycles plus dryer cycles to match. We also painstakingly examined 135 fabric stain strips with an industrial-grade reflectance colorimeter to precisely determine the effectiveness of each detergent.  And when all was said and done, the clear winner was Tide HE Turbo Clean liquid. It was far and away the best at eliminating a host different types of stains and soils. The second best cleaner in our group was another Tide product, Tide Pod 3 in 1 HE Turbo pods. Its stain-fighting abilities came close to liquid Tide. It cleaned with consistently good results from load to load too. That’s something the other detergent pod in our test group, All Mighty Pacs Free and Clear, failed to do. In general, All’s laundry pods couldn’t remove stains as well either.

Tyler Lizenby/CNET A note on high-efficiency washing machines Decades ago, washing machines consumed a lot more water than today’s high-efficiency (HE) models. According to Energy Star, modern HE washers use 14 gallons of water per load. Standard washing machines, on the other hand, need 20 gallons. Because of this difference, you can’t use ordinary detergent in an HE washing machine. Instead, these appliances require specifically formulated HE detergent. Most washing machine models sold now are high-efficiency though. The popularity of HE detergents has risen as well, which is why we chose HE instead of standard soap for our test group.    38 7th Generation Tide Pods 6 All Pods The best budget detergent Rounding out our list of top three detergents is the Costco Kirkland Signature Ultra Clean HE Liquid. It came in third in our group with an average of 56.9% stain remaining. It did leave more of our test wine stains behind (45.3%). The same is true for cocoa stains with 54.8% of those still clinging to our test strips. However, you can grab a huge 194-ounce container for $13.59. That calculates to just 7 cents per ounce, the most affordable detergent in this group. Despite its rock-bottom price, the detergent came close to matching Tide’s stain-removing power. Gain The dirt on detergent testing Scientifically evaluating the effectiveness of detergent is a rigorous, labor-intensive process that’s similar to the method we use to test washing machines. There’s a few key differences though. First, we stuck with one washing machine. In this case we used the Whirlpool WTW7500GC. We chose this appliance partly for our own convenience. It was already sitting in a berth inside our test lab. And since we thoroughly tested the washer during the review process, its performance was a known quantity. Using the same washing machine throughout testing also controlled for any appliance-related variables. For each brand of detergent, we performed three test runs. With nine specific detergent brands, that comes to a minimum of 27 washing machine cycles. And after we finished the test cycles, we ran additional wash cycles with just water to purge any residual soap. We didn’t assess the mechanical action of the washing cycle, like we do when we test individual washers. That’s because how physically hard or gentle a machine is on fabric is a characteristic of each individual washer, not the detergent it’s using.  hwtlaundryphotos-8.jpgEnlarge ImageHere are examples of two cloth stain strips. The top is a strip before washing. Below it is a strip after washing. Chris Monroe/CNET Otherwise, our methodology is identical. Inspired by guidelines laid out by the Association of Home Appliance Manufacturers (AHAM), we use 8-pound loads of laundry, with the same test items in each run. That includes a mix of “filler materials” such as fitted sheets, hand towels and pillow cases, plus specially calibrated cloth stain strips. These strips, which we buy from Swiss test material company Swissatest, meet AHAM’s strict guidelines for soil consistency. Each cloth test strip has five stain areas, each soiled by a different mixture of contaminants. The stains are as follows: sebum (skin oil), carbon (black), blood (pig’s blood), cocoa (chocolate and milk) and red wine (aged).  Each is designed to represent the chemical and physical properties of numerous similar substances. For instance sebum mimics the natural oils produced by your skin. Carbon represents petroleum byproducts like motor oil and mineral oil. Blood is a good predictor of protein-based pigments including grass stains. Cocoa simulates a range of organic pigments, such as stains caused by coffee and chocolate.  hwtlaundryphotos-3.jpgEnlarge ImageWe use an industrial reflectance colorimeter to take readings of our washed stain strips. Chris Monroe/CNET We score the results for each load with the help of a reflectance colorimeter. The sensitive tool allows us to measure the percentage reflectance of each test strip stain, both before and after washing. Comparing these two values then gives us the percent change that has occurred. From there we can calculate a percentage of how much stain a detergent removes (and leaves behind).  detergent-photos-2Enlarge ImageWe found that Tide HE Turbo Clean liquid was the best at removing stains in our test group of laundry detergents. Tyler Lizenby/CNET The best detergent for everything Hands down, Tide HE Turbo Clean liquid is the best detergent. Across the board, Tide got our test loads cleaner, and with the least stains remaining, regardless of the substance. It really shone when it came to stains for wine and cocoa. Only an average of 36.6% of wine stains remained after washing. That number might sound high, but overall it’s actually pretty good, especially compared with the other detergents.  For instance, the worst detergent for removing wine stains was Arm & Hammer Clean Burst. The liquid laundry soap left 52.3% (average) of its wine stains behind on our test cloth strips. And on average Tide left just 40.2% of cocoa stains behind. All Free and Clear liquid was the least effective at ridding fabric of cocoa. After washing, 79.6% (average) of cocoa stains still remained on its test strips.  best-detergents-four-group-correctedEnlarge ImageBoth All and Arm & Hammer had trouble removing cocoa stains. Tyler Lizenby/CNET Across all five tough stains, Tide left 52.1% (average) of staining behind. That makes it the best overall performer in this group of detergents. Tide doesn’t come cheap though. Priced at $11.97 for a 100-ounce container (12 cents per ounce), it’s the most expensive of the liquid detergents we tested. detergent-photos-3Enlarge ImageTide Pods 3 in 1 HE Turbo detergent pods were almost as good at attacking tough stains as liquid Tide. Tyler Lizenby/CNET The best detergent pod Tide triumphed here again. Each little Tide Pod 3 in 1 HE Turbo got test loads virtually as stain-free as Tide liquid did. With an average of 53.5% of stains remaining, it was second best. The Tide Pods were also proficient fighters of red wine (43.6% remaining) and cocoa stains (44% remaining). best-detergents-five-group-correctedEnlarge ImageIn terms of fighting stains, both Tide liquid and Tide pods came out on top. Tyler Lizenby/CNET More impressive though was the consistent clean these pods provided. Across three test runs, the Tide pods notched stain removal results that were essentially identical (52.8%, 53.5% and 54.2% stain remaining). The other laundry pod in our group (All pods) fared much worse. Not only did it leave clothes dirtier on average (58.2% stain remaining), performance was wildly inconsistent between each wash (57.1%, 63.2% and 54.3% stain remaining). If saving cash is your motivation, however, look elsewhere. At $20 for container of 81, these pods are pricey. They work out to about 25 cents per pod (one pod per load).
