After hours spent trying to repair damages to the Demerara Harbour Bridge (DHB), commuters and traffic will soon return to normal as Public Infrastructure Minister David Patterson has announced that repairs are complete.Crowds of commuters inconvenienced after the DHB was out of commissionIn a statement on his social media account on Wednesday, Patterson revealed that staff of the DHB have completed the realignment of the bridge, which went down after being struck by a barge on Monday.He also announced that by today, the bridge will be opened completely to all traffic. This comes after the bridge was opened to light traffic on Tuesday, while persons living on West Bank Demerara (WBD) were forced to use water taxis to commute.On Monday, the very day that school reopened, a barge and tug slammed into the southern side of the Demerara Harbour Bridge. The impact shifted the spans and resulted in serious damage to a car that was caught in between two separated plates.Emergency actions were deployed. Engineers had also noticed that structure was shifted from its aligned position between the two damaged spans.As the morning wore on, there was confusion as passengers fainted while waiting to board speedboats at the Stabroek Stelling. While some commuters complained about the inordinate time it took to board, others complained about the stagnant location and the toxic air.Floating at 1.25 miles, the Demerara Harbour Bridge has the distinction of being the longest floating bridge in the world. It is a strategic link between the eastern and western banks of the Demerara River that facilitates the daily movement of a large numbers of vehicles, people and cargo.The structure was built in the 1970s, but was opened in July 1978 with the expectation of lasting only 10 years. As such, there have been concerted efforts by both the previous and current administration to build a new bridge, though the latest efforts have been marred by procurement controversies.In 2017, a feasibility study and design for a new Demerara River Bridge was done by Dutch company LievenseCSO. The project team had included officials from the Demerara Harbour Bridge Corporation and Transport and Harbours Department.That the feasibility study had determined the proposed location of Houston-Versailles as the most ideal. A low-level bridge with a movable part and three-lanes was recommended for construction.However, another study had been completed back in 2013, when the Demerara Harbour Bridge Corporation had collaborated with the then Public Works Ministry to carry out a pre-feasibility analysis. That study had concluded that a ‘fixed, high level’ bridge was the best option to pursue, rather than the retractable model.
CALGARY — A Calgary-based company that drills for natural gas in Colombia says it has started making and selling liquefied natural gas to supply energy consumers in the South American country.Canacol Energy Ltd. says it is the first to offer the service which will allow customers to replace fuels such as diesel, fuel oil, compressed natural gas and propane that cost more or have higher emissions than LNG.The company says it installed four small natural gas liquefaction modules purchased from Galileo Technologies of Argentina at its main gas processing facility in northern Colombia.- Advertisement -It says the modules are capable of super-cooling 2.4 million cubic feet per day of gas to create 29,000 gallons of LNG to be sold at the plant gate for distribution via trucks throughout the country.Canacol says Colombia consumes 65 million cf/d of compressed natural gas and 80 million cf/d of propane, with a significant amount of the propane being imported from the United States.The company says it is also in negotiation with Galileo to form a joint venture which would install LNG terminals at other natural gas pipelines in Colombia.Advertisement “Given the limited capacity of the gas pipeline infrastructure in Colombia, industrial, commercial and residential consumers not located along existing pipeline routes currently use 145 million cf/d of compressed natural gas and propane that is transported long distances via truck as an energy source,” said Canacol CEO Charle Gamba in a news release.“LNG can replace diesel, fuel oil, compressed gas, propane, and other fuels at a considerable reduction in price given the relatively lower cost of natural gas and the large volume of liquefied gas that can be transported by truck.”Companies in this article: (TSX:CNE)The Canadian PressAdvertisement

DONEGAL County Council’s director of finance services Gary Martin has admitted that three in four households in the county have NOT paid the household tax.Mr Martin said that only 25 per cent of those liable had paid.There was a “substantial element of protest” associated with this rate, Mr Martin said in an interview with RTE. “I think there has been a substantial anti-payment campaign reflected in Donegal from the very early days of this year with regard to the payment of the charge and that clearly has had an impact on the numbers that have paid on the ground,” he said.Meanwhile Socialist MP Joe Higgins will address supporters in Letterkenny this evening.He will speak at the Station House Hotel at 8pm.* Pictured Above: Can’t Pay protestors from Falcarragh/Gortahork in Dublin on Saturday.

7 January 2014The stage is set for the opening ceremony of the African Nations Championship 2014 (Chan), which will be held at the Cape Town Stadium on Saturday.The opening ceremony will take place ahead of the kick-off of the first game between hosts South Africa and its neighbour Mozambique. The tournament will run until 1 February.Mvuso Mbele, chief executive of the local organising committee (LOC), said no compromises had been made in the planning of the tournament: “The opening ceremony of any event sets the tone for what is to follow and that is why we have pulled out all the stops to ensure that Africa and the rest of the world experience one of the most memorable ceremonies in history. We urge everyone to get their tickets now and join us at the Cape Town stadium as we celebrate Africa.”Award-winning musician Micasa as well as celebrated choreographer Somizi Mhlongo will be part of the line-up that will entertain fans during the opening ceremony.VolunteersMeanwhile, more than 600 volunteers from all over the city are being trained by the LOC to give them the skills and knowledge they will require to ensure the tournament runs seamlessly, the City of Cape Town said on its website.The volunteers will be involved in marketing, media accreditation, transport, logistics and protocol services. “The aim of the volunteer programme is to bring people from all walks of life together to lend a helping hand in staging this significant event – the first major soccer tournament in Cape Town since the 2010 Fifa™ World Cup,” the city says.South Africa was named as the host after Libya gave up the right to host the event because of the continuing upheaval in the country. Libya will instead organise the 2017 tournament, which had been due to take place in South Africa.Cape Town will serve as tournament headquarters and Bafana Bafana’s home base, in addition to hosting 16 of the championship’s 32 matches and staging the opening and closing ceremonies. The tournament’s remaining matches will take place in Polokwane and Mangaung.Teams from 16 African countries will be compete in the tournament, kicking off with the opening match between South Africa and Mozambique at the Cape Town Stadium on 11 January. TicketsTickets are on sale at Shoprite/Checkers stores and Computicket outlets. Prices range from R40 to R200.Match tickets are to be sold in three phases:Phase 1 – general group stage tickets. Sales are open.Phase 2 – for quarter-finals, semi-final and final match tickets without knowing which teams are placed. From 6 to 18 January.Phase 3 – for the semi-final and final match tickets, after knowing which teams have made it to the top eight for the semi-final and final matches, including the third and fourth play-off matches the final phase. From 19 to 22 January.TeamsThe 16 teams in the tournament are divided into four groups:Group A: South Africa, Mali, Nigeria and Mozambique. Will compete at the Cape Town Stadium.Group B: Zimbabwe, Uganda, Burkina Faso and Morocco. Will play their matches at the upgraded Athlone Stadium.Group C: Ghana, Libya, Ethiopia and Congo. Will play matches at the Free State Stadium in Manguang and at the Peter Mokaba Stadium in Polokwane.Group D: Democratic Republic of Congo, Gabon, Burundi, Mauritania. Will play matches at the Free State Stadium in Manguang and at the Peter Mokaba Stadium in Polokwane.MatchesThe Bafana Bafana matches will be played at the Cape Town Stadium:Bafana Bafana versus Mozambique on 11 January at 6pmBafana Bafana versus Mali on 15 January at 5pmBafana Bafana versus Nigeria on 19 January at 7pmTraining venues include Green Point FC, Green Point Athletics Stadium, NY 49, Site C in Khayelitsha. Erica Park, Belhar is a back-up venue.More about the Chan tournamentThe CHAN tournament, established in 2007 and first contested in 2009, is administered by the Confederation of African Football (CAF) and is played between the 16 best national teams in Africa.National teams have to qualify for the event and may only feature players active in their local leagues. Players who play abroad – regardless of where, even in Africa – do not qualify to take part in the competition.SAinfo reporter, SAnews.gov and City of Cape Town
Convection is the transfer of heat by moving molecules from one place to another. Warm air rises, and these convection currents carry heat — for example, this is the primary means that heat is delivered to a room from baseboard convectors (often called radiators). In a vacuum there are far fewer air molecules, so convection of heat nearly stops.Only radiant heat flow occurs to a significant extent in a vacuum, because radiation is not dependent on air molecules. That’s why low-emissivity surfaces are so important in vacuum panels. The Stanley Thermos bottle has a very shiny, low-emissivity (low-e), inner surface that helps to control radiant heat transfer; the same sort of low-e surface is included in various vacuum insulation panels.The net result is that an inch-thick vacuum insulation panel can provide a center-of-panel insulating value of R-25 or even more — compared with R-6 to R-7 for standard rigid foam insulation. I’ve recently worked on revising the BuildingGreen Guide to Insulation Products and Practices (available as part of a webcast), so I’ve been steeped in all sort of insulation materials, including some oddball products. One of those is vacuum insulation — the principle of a Thermos bottle.In theory, vacuum insulation is a great idea. To understand why, it helps to know a bit about heat flow. Alex is founder of BuildingGreen, Inc. and executive editor of Environmental Building News. In 2012 he founded the Resilient Design Institute. To keep up with Alex’s latest articles and musings, you can sign up for his Twitter feed. Using a vacuum to insulate more than our coffeeIf a vacuum works so well to keep our coffee hot all day, why not use one to insulate our houses? Vacuum insulation panels have been used to insulate some high-tech demonstration homes, such as entrants in the Solar Decathlon student design competition in recent years, but high cost makes them impractical for real buildings.There’s also the problem that puncturing that vacuum insulation panel will significantly reduce its insulating performance. (I can imagine how bummed one would be after spending thousands to insulate a home with vacuum insulation panels and then hearing a hiss while hanging a painting!)However, these vacuum insulation panels (sometimes called VIPs) could make a great deal of sense in certain value-added products like refrigerators, freezers, water heaters, and entry doors. Whirlpool actually used a VIP that Owens Corning produced for a while (the Aura panel) in a high-efficiency refrigerator in the mid-1990s, but then dropped both the refrigerator and the use of VIPs.But I believe the benefits of R-25 or more in a one-inch-thick panel are significant enough — especially as we try to get more usable volume in refrigerators without growing the exterior dimensions — to warrant the embrace of vacuum insulation. These could also be a great solution for exterior doors that are notoriously poorly insulated — as I’ve written about in this blog.There are at least a half-dozen manufacturers of vacuum insulation panels today. Most, including Microtherm and Nanopore, produce panels that have a rigid, porous substrate surrounded by an impermeable metal skin. A new VIP on the marketThe latest VIP to come along is made by Dow Corning (no relation to Owens Corning). This panel, not yet widely available, is one inch thick and has a center-of-panel insulating value of R-39 and a “unit R-value” (accounting for the edges) of R-30, according to the company.The Dow Corning product has a core made of fumed silica cake, a remarkable “microporous” material that provides R-8 per inch even without a vacuum. This material allows a very high insulating value even with a softer vacuum. The core is reinforced with silicon carbide and polyester fibers for structural support, and it is encased in an inner layer of polyethylene and an outer layer of polyethylene, polyester, and aluminum. The panels are vacuum-sealed, and the edges are heat-sealed.According to an Environmental Building News article, these Dow Corning panels should cost $10-12 per square foot. At that cost, I believe VIPs can be very practical for those appliance and exterior door applications noted above. How a vacuum slows down heat transferThere are three modes of heat transfer: conduction, convection, and radiation, and if we remove most of the air molecules from a space — as occurs when we draw a vacuum — we largely eliminate the first two of those heat transfer mechanisms.Conduction is the flow of heat from molecule to molecule. It’s the reason a cast-iron skillet handle heats up. But thermal conduction also occurs across a layer of air, as kinetic is transferred from one air molecule to the one next to it. If we remove most of those air molecules by creating a vacuum, there will far less conductive heat flow. RELATED ARTICLES A Few Product Highlights from GreenBuildGBA Product Guide: Dow Corning Vacuum Insulation Panels Vacuum Insulation Panel The “hardness” of a vacuumThe key property of a vacuum is its pressure, or how “hard” it is. We often measure that with Torr units. One Torr is exactly 1/760th of a standard atmosphere (1.3 x 10-3 atm), or approximately 1 mm of mercury. With a very hard vacuum, more of the air molecules are sucked out, resulting a greater negative pressure. The walls of a typical Stanley Thermos bottle contain a relatively hard vacuum of 10-6 Torr. With such a hard vacuum, that Thermos bottle can keep coffee hot all day. By comparison, the vacuum in a flat vacuum insulation panel is typically no more than 1/1000th as strong (10-3 Torr).The harder the vacuum, the more difficult it is to maintain it. Thermos bottles are made with a cylindrical design for optimal strength. With flat panels, it’s very hard to achieve comparable strength and maintain such a hard vacuum, particularly at the edges.
Related Posts IT + Project Management: A Love Affair 3 Areas of Your Business that Need Tech Now brian proffitt Just three months after Apple’s public relations snafu that saw the company mysteriously leave the computer industry’s EPEAT environmental standards program and then come back again under a cloud of shame, it turns out the Mac/iPhone maker had little to worry about. All of the products Apple submitted to the registry, including the Retina MacBook Pro at the heart of the original controversy, have now qualified for EPEAT status anyway.That development, though, has gotten a lot of folks angry, including environmental organization Greenpeace and noted repair site iFixit.org, who have accused EPEAT of watering down its standards in order to accommodate what they describe as Apple’s decidedly non-environmental hardware.The Electronic Product Environmental Assessment Tool (EPEAT) registry rates devices on their “greenness.” based on factors such as longevity, upgradability and recyclability. EPEAT is sponsored by grants from the Environmental Protection Agency (EPA) and revenue from industry participants in its registry, specifically annual fees based on a company’s sales and revenue in an evaluated product’s category, according to Sarah O’Brien, Director of Outreach and Communications for EPEAT.Of EPEAT’s 47 participants, O’Brien emphasized, “Apple pays only a small part of our total revenue.”O’Brien’s statement was aimed at countering comments from Greenpeace and iFixIt that implied that because Apple was essentially paying for its own certification, the company was able to call the shots as far as receiving Gold certification for the Retina MacBook Pro.The Retina Lightning RodThe Retina MacBook Pro has become the poster child for Apple’s avoidance of green standards. In June, criticism for Apple’s recyclability came to a head when iFixit noted that the laptop used a lot of glue to bind the display, case and boards within the device together. In iFixit’s opinion at the time, this makes the device very hard to service and recycle.It’s an assertion iFixit is very strongly maintaining.“Apple’s Retina MacBook Pro – the least repairable, least recyclable computer I have encountered in more than a decade of disassembling electronics – was just verified ‘Gold’, along with four other ultrabooks,” blogged iFixit’s Kyle Wiens. “This decision demonstrates that the EPEAT standard has been watered down to an alarming degree.”Greenpeace went even farther in its assertions.“Apple wanted to change the EPEAT standards when it knew its MacBook Pro with Retina Display would likely not qualify for the registry in July of this year – now EPEAT has reinterpreted its rules to include the MacBook Pro and ultrabooks,” Greenpeace IT analyst Casey Harrell said in a statement to PC World.“Is it a coincidence?” Harrell continued. “It’s unclear why EPEAT caved in, but the impact is that EPEAT has confused consumers and businesses who want to buy green electronics that can be repaired and will last a long time, and sets a dangerous trend for the burgeoning market of ultrabooks.”EPEAT Fires BackO’Brien was equally assertive in her defense of EPEAT’s evaluation of the Retina MacBook and other products.“We are a standards-based program,” O’Brien told me, referring to the IEEE 1680.1 standards. “Our verification and registry of products is based on those standards.”O’Brien’s boss, CEO Robert Frisbee, also defends the groups actions.“Once standards are defined and agreed-upon, EPEAT’s focus becomes verifying products that are on the registry. EPEAT staff are not directly involved in the investigations, and do not have any authority to alter the requirements to let participants off the hook. Through investigations by independent contractors, products are either found conformant to the standard or not,’ Frisbee wrote in EPEAT’s blog this week in reaction to the media kerfuffle.Both EPEAT staff members emphasized that since EPEAT follows the letter of the standards when it has products tested, it is doing its job as expected. O’Brien outlined how many stakeholders, from manufacturers to environmental non-government organizations (NGOs) like Greenpeace, are involved in the standards-building process.“The ideal situation is that everyone brings their perspectives and goals to the standards discussions,” O’Brien said. But, she added, those goals have to be balanced with the need to actually have products be able to achieve the standards at some point.O’Brien defended the notion that EPEAT’s standards are easy to attain. “When the Registry first launched, there were no Gold products for a year.”Currently there are 1,573 active Gold-rated products in EPEAT’s Gold level of certification. By contrast, 671 have achieved Silver status and 38 have Bronze status.EPEAT’s Present and FutureTo meet minimal EPEAT standards, products have to meet 28 baseline regulatory requirements set by the EPA. To get EPEAT’s additional levels of certification (Bronze, Silver, and Gold), the product has to rate well in optional criteria such as the reduction/elimination of environmentally sensitive materials and design for end-of-life.While EPEAT is not itself a government organization, its product ratings can be important to governments. U.S. federal agencies, for example, are required to give EPEAT-registered products preference in procurement decisions. This, more than anything else, is why most people believed Apple returned its products to EPEAT’s registry in July.What is not clear is why Apple would leave EPEAT to begin with. O’Brien said that her organization still does not know what prompted Apple’s initial departure.For now, EPEAT and other organizations, including the EPA, are beginning talks to revise the IEEE standards. O’Brien says this is critical in order to keep the standards relevant to the fast changes in hardware design.“We have to get the goal and vision out head of rapid changes,” O’Brien said.Image courtesy of Shutterstock / ReadWriteWeb.

It was a dream come true for Indian ace badminton player Saina Nehwal. She had her flight of fancy on Friday, when she flew Kiran MK II Jet trainer aircraft of the Indian Air Force and joined the prestige club of elite sportspersons to receive the honour.Accompanied by Group Captain Nagesh Kapoor, a visibly excited and equally nervous 22-year old Saina, wearing the military green uniform, boarded the aircraft and had a 22-minute sortie in the skies at Air Force Academy, Dundigal on the outskirts of Hyderabad. And it was a dream flight for the Olympics bronze medallist, who was given the opportunity as an inspiration to the young cadets at the academy to work hard and bring laurels to the country.Kiran MK II aircraft is being used by the Air Force to train its rookie pilots before they move to fly other fighter and transport aircraft.Saina Nehwal waves as she alights after flying in a Kiran MK II Jet trainer aircraft of the IAF.Though Saina appeared nervous before she was taken to the aircraft, she was all smiles and excited when she returned to the hanger after the flying in the skies. It was obvious that she was on Cloud Nine. “It was a very exciting experience. It is a dream of everybody to fly in the jet aircraft and I am thankful to the Indian Air Force Academy for giving me this wonderful opportunity. I am here because of the badminton game,” Saina told mediapersons after completing the sortie.Asked how she felt amidst the clouds, the ace shuttler said honestly she had felt nervous. “I was shouting no-no, when we passed through clouds. But I enjoyed the ride, as it was very interesting. I have been promised that I would be taken in a fighter jet next time,” she said.Before entering the academy, too, Saina appeared very exciting. Asked whether she was feeling as nervous as she was playing with the Chinese shuttler at the Olympics, she said: “Obviously, I feel more nervous now, because I never faced this experience in the past.”Interacting with the cadets later, Saina said she was proud to be associated with the Indian Air Force and its pilots. “Everybody should serve the country in the best possible way in whichever field they may be in.”Saina was invited to the Air Force Academy as a special guest for the closing ceremony of the Inter Squadron Sports Championship. She also witnessed the closing ceremony of the sports championship, where she played an exhibition badminton match.Saina joins the select group of sportpersons who were fortunate to get associated with the Indian armed forces. Indian cricket captain Mahendra Singh Dhoni was made an honourary Lieutenant Colonel in the Territorial Army while legendary Sachin Tendulkar, became the first sportsperson to be conferred a rank by the Air Force when he was made an honourary Group Captain. Both the cricketers also share the distinction of enjoying a sortie in a Sukhoi fighter aircraft — SU-30MKI.advertisement
