When water causes sickness

first_imgFor almost anyone, the sight of a well pump clogged with sediment would mean bad news. For the residents of Pinalito, Dominican Republic, it meant the risk of drinking bacteria-contaminated water from the river. For the Harvard College Engineers Without Borders (HCEWB), however, it meant the chance to brainstorm a slew of solutions — and determine which would work best.In January, a team of students led by Casey Grun ’14 and Tunde Demuren ’15  ventured to Pinalito for nine days to learn about the village’s resources and needs. They noticed that the pump had been installed improperly, letting water out and sediment in, and the original contractor was long gone.Pinalito is a community so rural it doesn’t show up on Google Earth, and has only 20 to 30 permanent households. The economy is based on agriculture, and the residents have an average income of only about $7.50 a day. Not only did the 100 villagers need access to clean water, but they needed a long-term, sustainable solution they could own and maintain themselves.HCEWB, the Harvard chapter of the humanitarian organization Engineers Without Borders USA, contributes to environmentally sound and economically sustainable engineering projects all over the world, while promoting global consciousness on campus. Supported in part by a Nectar grant from the Harvard School of Engineering and Applied Sciences (SEAS), the group also develops programming and builds mentoring relationships among engineers and students in the Cambridge area.HCEWB had first traveled to the Dominican Republic in 2007 on the suggestion of the Constanza Medical Mission, a Massachusetts-based Catholic charity that was treating many waterborne illnesses there and seeking an engineering-based solution to the problem.The Harvard group began working to improve the contaminated water supply in the village of Tireo Abajo, just outside the small city of Constanza. By the summer of 2011, it had distributed point-of-use water filters throughout the community. The students were then referred to nearby Pinalito, visiting last March and again in January to assess the community’s general needs.In one busy week, the group conducted a detailed land survey with 260 points of interest to create a regional map using GIS, enabling an in-depth analysis of the geography. The team also tested the quality of the community’s existing water sources, including the river, mountain springs, and tinitas, sand-enclosed water pits from which the villagers collected most of their water. The team measured arsenic levels, turbidity, and nitrate levels, as well as fecal coliform bacteria and E. coli in these sources, suspecting that the waterborne diseases prevalent in the community came from its drinking water.Manuel Ramos ’14, Leah Gaffney ’15, Tunde Demuren ’15, and Dipti Jasrasaria ’16 meet with elementary schoolchildren in Tireo Abajo to discuss water sanitation and the prevention of waterborne illness.The team found that the sandy tinitas actually filtered out a good portion of the bacteria in the water. The mountain spring water was the cleanest, but also harder for the villagers to access. The residents used this initial data to decide where they should collect water in the short term, until the pump was fixed or replaced. Some families also began using biosand filters in their homes.For the students working on the project, said Grun, “The biggest challenge is the constant tension between urgency and prudence. The natural inclination is to want to do something as quickly as possible, but we want our solution to be effective and sustainable — and this requires time to do a careful analysis and design.”Speaking Spanish, the Harvard students also took time to teach lessons on water quality to children ages 6 to 13at three schools. The team designed and presented a curriculum covering water purification and good sanitation, and demonstrated the use of Petrifilms to compare bacteria compositions in different water sources. The Harvard students even created a comic book chronicling the adventures of Señor Agua, or “Water Man,” against a villain who contaminates water sources. A forum teaching water treatment and sanitation included parents in the educational initiative.Throughout the process, HCEWB ensured there was open communication with the community.“Though the Harvard students may be separated geographically and culturally from Pinalito during our academic semesters, we really work hard to form deep connections with our local contacts and ensure all decisions are made jointly,” said Grun, who is studying biomedical engineering and computer science.Before leaving Pinalito, for instance, the Harvard team held a community meeting to explain the results of the water testing and discuss possible solutions to the problem. Together, the participants determined that their most viable options were to dig a well near the river or further uphill, pipe water from a faraway spring, or restore the old, nonfunctional well.Back in Cambridge, the students are now analyzing the four possible solutions, using the data they previously collected. They regularly call their contacts in the Dominican Republic to check on conditions and get feedback on their proposals.“It’s been very exciting to work on a real-world problem,” Grun said, “but it’s a weighty responsibility as well. The stakes are higher. Our actions, positive or negative, have a measurable effect on the health and well-being of the residents of Pinalito. This isn’t the case for our exams or problem sets, which makes it both inspiring and intimidating.”The group has four months before its next trip to evaluate the options and decide the best to implement.“Today’s largest engineering challenges are in global infrastructure and how this infrastructure can meet the needs of the 7 billion people who live on earth,” said the group’s advisor, Christopher Lombardo, assistant director for Undergraduate Studies in Engineering Sciences at SEAS. “Student groups like Engineers Without Borders provide a mechanism for students to make global contributions during their college education.“The experience they gain by working on these projects also makes these students highly competitive for employment with companies or institutions that are internationally focused or have offices worldwide,” Lombardo said.last_img read more

ClassNK Grants AiP to NS United Kaiun Kaisha & Imabari for LNG-Fueled Capesize

first_imgClassification society Nippon Kaiji Kyokai (ClassNK) has granted an Approval in Principle (AiP) to Japanese shipbuilders NS United Kaiun Kaisha and Imabari Shipbuilding Co. for their joint project on the concept design of an LNG-fueled Capesize bulker.According to Imabari, the design adopts a low-pressure dual-fuel engine for the main engine, which enables the use of gas that has naturally vaporized (BOG: boil-off gas) from the LNG tanks in the main engine without any waste, thereby reducing the burden on the environment and lowering running costs.“By installing two Type C LNG tanks at the stern, which are considered to be cost-competitive and are comparatively easy to install, it is possible to build an LNG-fueled vessel without significant changes to the conventional vessel’s basic design.“This basic design can achieve CO2 emission volumes that are 30% less than the reference line as required under EEDI Phase 3 by the IMO,” the yard said.Japanese shipbuilders have been very busy with the advancing of their projects in developing ships fuelled by LNG. Namely, earlier this year, Kawasaki Heavy Industries (KHI) secured an AIP for the concept design of an LNG-fueled 207,000 dwt bulk carrier.Featuring a length of around 300 meters and a width of 50 meters, the new LNG-fueled bulk carrier keeps its cargo space as large as that of conventional oil-fueled ships by configuring the LNG fuel tank behind the accommodation in the stern.Powered by low-speed, dual-fuel diesel engine, the ship achieves significantly reduced emissions of CO2, NOx, SOx, and particulate matter when using LNG as fuel, meeting Energy Efficiency Design Index (EEDI) Phase 3 requirements.The development of LNG-fuelled vessels is being pursued across the shipbuilding sector amid an anticipated increase of the global demand for LNG-fuelled ships as part of ship-owners’ switch to greener fuels.last_img read more

No excuses from Giggs

first_img Press Association Ryan Giggs believes the players and not manager David Moyes should take responsibility for Manchester United’s lacklustre start to the season. The Red Devils have claimed just seven points from their opening six Barclays Premier League games and were held to a 1-1 draw by Shakhtar Donetsk in the Champions League on Wednesday night when Giggs made his 145th appearance in the competition. That has put some pressure on Moyes, who had the unenviable task of replacing Sir Alex Ferguson in the Old Trafford hotseat after his fellow Scot had enjoyed a trophy-laden 27 years at the club. center_img And while veteran midfielder Giggs admits it was always going to be difficult to replace a man who brought two European Cups to United, the Welshman insists that it is the players and not the manager who must stand up and be counted. “Sir Alex was a great manager and a great influence on the team and the club. You are going to miss someone like that,” he told various national newspapers. “But I don’t think that is an excuse when individuals aren’t playing as well as they can. We are not playing well as a team. “We haven’t got injury problems as we have had in the past. There is no excuse. “It hasn’t been a great start to the season but the good thing about that is we have plenty of time to turn it round. “We know what this club is like, it is ups and downs and we don’t get carried away if we are flying and we don’t get carried away when we are not playing well. “I can’t put my finger on what has happened. We have just not played as well as we can, both individually and as a team. “The results have shown we haven’t played as well as we can do. But we know the quality in the dressing room. “We’re the champions so we showed that quality last year and we have to show it again.” last_img read more

LA Dodgers closer Kenley Jansen focused on winning, not free agency

first_imgTORONTO >> Kenley Jansen has a vested interest in the Dodgers solving their annual bullpen issues.As closer, Jansen is a man on an island, waiting for leads to be brought to him. The more often they make it to the ninth inning, the more often he will pitch — and the more often he will be able to polish his resume for a likely foray into free agency next winter.It hasn’t been easy. Going into Sunday’s game, Dodgers relievers — other than Jansen — had a 4.27 ERA and 1.39 WHIP in the seventh inning or later. Dodgers manager Dave Roberts has already cycled through multiple options in the setup role in front of Jansen with Chris Hatcher, Pedro Baez and Joe Blanton each having their moments — and failures. He brought Jansen into the eighth inning Sunday for the second time already this season, asking him for a four-out save.“You just gotta be tough. That’s what I think,” said Jansen who began his big-league career in a setup role. “Mentally, you’ve just got to be tough. That’s what we’re missing sometimes. “I can have the worst year of my career and I feel all 30 teams will still want me,” he said. “This is not my first year I’ve been closing. People should know what I can do.“If I focus on that (free agency and his next contract), it’s going to take away from what I love which is to go out there and do my best to dominate the ninth inning and help my team win. It’s not about money.”Jansen said he has long since put away any confusion or concern over the Dodgers’ attempt to trade for Aroldis Chapman last winter. There have been no overtures from the Dodgers to open negotiations on a contract extension either but Jansen dismisses that, saying all he has ever known is playing on one-year contracts.“When it comes time, they’re going to do what they’re going to do,” he said. “You can’t worry about the future today. You take care of the future by taking of your business today.“My motivation is to be the best I can possibly be in this game and help my teammates. It’s not about a contract. I just want to win a championship in 2016. I feel like we have the team to do it. We just have to do it on a more consistent basis.”AlsoThe Dodgers have still not made a roster move to add right-hander Casey Fien who was claimed off waivers from the Minnesota Twins on Saturday. Fien has three days to report to the team. Dodgers manager Dave Roberts said he expects Fien to join the Dodgers in Los Angeles at some point. However, Fien does have options left and could be assigned to Triple-A. Hyun-Jin Ryu was moved to the 60-day disabled list in order to clear a 40-man roster spot for Fien. … Right-hander Mike Bolsinger went four innings in his first rehab start for Triple-A Oklahoma City Saturday, allowing two runs on three hits (including a home run). He threw 46 pitches and struck out three. … Right-hander Brandon Beachy received a platelet-rich plasma injection in his elbow. Beachy has not pitched since experiencing discomfort in his elbow during spring training. Beachy has twice undergone Tommy John surgery on his right elbow.

I need my guys so I hope they get it going. I know they will.”If they don’t, Jansen is not concerned about it costing him money on the free agent market. The 28-year-old Jansen leads the majors with 11 saves in 11 chances this season, having allowed just one run (in a non-save situation) on seven hits and one walk in 13 1/3 innings while striking out 14.“This game is never going to run out of money,” Jansen said with the laidback ease of his island background. “I work for a multi-billion dollar corporation which is the Dodgers. There are 29 other teams that are part of a multi-billion dollar corporation that is Major League Baseball. It will take care of itself. I’m just going to do what I do.”He has done it pretty well. Since taking over the closer role in 2012, Jansen has been one of the best in baseball. He has converted 144 of 162 save situations including his past 23, stretching back to last season. He needs just eight more saves to match Eric Gagne’s franchise record (161). His career rate of 13.8 strikeouts per nine innings is one of the highest in baseball history.All of that, Jansen is confident, will get him paid very well by someone regardless of how the Dodgers’ bullpen sorts itself out this season.last_img read more

Helping children stay safe online

first_img4 June 2012 The government has partnered with Google South Africa and the UN Children’s Fund (Unicef) in launching the South African version of the Google Online Family Safety Centre. The website, www.google.co.za/familysafety/, is available via computer or mobile in English, isiZulu and Afrikaans, and aims to assist parents and caregivers in helping their children navigate the internet safely. It carries advice on keeping families safe online, cyber bullying, safety tips from other parents, as well as a platform for reporting inappropriate online content. The site forms the first part of the Online Child Safety Campaign, launched by Minister for Women, Children and People with Disabilities Lulu Xingwana in Johannesburg last week. The second phase of the campaign will see workshops taking place in schools and communities to train parents, teachers and children on how to stay safe online.Empowering parents and children Speaking at the launch, Xingwana said social networks were central to the day-to-day lives of many young people, and it was important for parents to have regular, open discussions with their children about their experiences on the internet. “Even though extensive efforts have been put into protecting children online in other countries, not much work has been done in South Africa and the southern African region,” Xingwana said, adding that the campaign was the first of its kind in the country involving government, the private sector and civil society. She said parents’ approach should not be to scare children away from technology but rather to empower them with ways in which they can use technology responsibly and protect themselves from possible harm.Mitigating online risks Google South Africa policy manager Fortune Mgwili Sibanda said that while the internet played a positive role in education and information, it also enabled some of the worst abuse of children. “The internet is growing at a [fast] pace and has become a playground for our children,” Sibanda said. “We are trying to mitigate the risks online by educating children on how to stay safe online. “We can’t block them from accessing the internet, as this may lead to them losing out on education and entertainment.” BuaNews and SAinfo reporterlast_img read more

R1bn investment sees new Corolla roll off the line

first_img5 February 2014 Toyota South Africa Motors on Monday started full production of the new Toyota Corolla – the 11th generation of the world’s best-selling car – following a R1-billion investment in its Prospecton manufacturing plant in Durban. Toyota South Africa Motors CEO Johan van Zyl said the company’s R1-billion investment was the second to be announced in the current phase of a capital expansion programme that started with a R363-million new parts distribution centre in Gauteng province in 2012. This followed a R8-billion investment programme that was completed in 2008 and that saw Toyota’s local production capacity increase to 220 000 units. In December, the company celebrated the production of its 1-millionth South African produced Corolla. “It is hard to believe that a mere two generations of the Corolla ago we were a manufacturing operation with South Africa as our sole market,” Van Zyl said in a statement. “Today the Corolla, a good example of leading-edge technology, is manufactured in high volumes for both the local and the export markets.” The new Corolla will be built in both left- and right-hand drive variants for the local and sub-Saharan Africa export markets. Van Zyl said the South African automotive industry’s transformation from local manufacturing and assembly operations to globally focussed manufacturing facilities was due in large part to the successful implementation of the government’s Motor Industry Development Programme (MIDP), which was designed to encourage high-volume local manufacturing and export programmes. “The environment created by the MIDP, and subsequently the challenges posed by the new Automotive Production and Development Programme (APDP), allows vehicle manufacturing facilities to invest in long-term projects that have long investment horizons,” he said. “The decision to invest in the production of the new Toyota Corolla was one taken well in advance of the start of production and one that considered the future economic prospects of South Africa and that of major Corolla export markets. “We believe that despite the current economic slowdown and currency pressures, the South African built Corolla will prove to be a good long-term investment.” SAinfo reporterlast_img read more
