first_imgLAHORE, Pakistan (CMC):Pakistan’s cricket authorities want West Indies to play a day-night Test during their tour in October as they prepare for their historic pink-ball Test against Australia in December.West Indies are set to play two Tests, five one-day internationals, and two Twenty20 Internationals during the series set for the United Arab Emirates, and media reports here say the Pakistan Cricket Board (PCB) has sent a proposal to the West Indies Cricket Board (WICB) to play one of the Tests under lights.Former Test captain Misbah-ul-Haq, an adviser to the PCB’s cricket committee, said it was important that the national team had practised with the pink ball before taking on Australia.”If you don’t have match practice, it will become difficult to play at Test level. It was one of the things discussed in the cricket committee’s previous meeting,” said Misbah.”The bowlers are at (an) advantage in the evening session, and it becomes very difficult for batsmen under lights. That is one reason the cricketers from other countries are also reluctant to play Tests under lights.”He added: “One more reason is the lack of match practice with the pink ball. The players have hardly played any cricket under these conditions at the domestic levels. They need more match practice before playing it at international level.”Even if the proposal is rejected by the WICB, the PCB plans to stage matches under lights during the first-class competition in order to prepare players.International games have not been played in Pakistan in over seven years because of the volatile security situation here.Earlier this month, the WICB rejected a proposal from the PCB to play limited-overs matches during the upcoming series on Pakistan soil.last_img read more

first_imgOn November 30th, 2014, 122 students from across British Columbia will travel to Vancouver and Richmond for a two-day educational experience. The selected students will get to attend the Grey Cup on Sunday the 30th and then they will attend the BC Lions Skills for Life Summit on Monday December 1st. The BC Lions have teamed up with the Ministry of Education and Pacific Northwest LNG to help young students from each school district learn about jobs in trades and show them the opportunities that are available for them. Additionally, the students will participate in a variety leadership workshops such as: prevention of bullying and violence against women, making positive choices, and avoiding gang involvement.Find Your Fit – which made a stop in Fort St. John on November 4th-5th – is a Province-wide education program for students in grades 6 through 10 to teach them about trades as well as give students a head start to hands on learning through apprenticeships and Dual Credit programs.- Advertisement -This education program is outlined in the Provincial Governments BC Skills for Jobs Blueprint – an action plan established to meet the future work demands of over 1 million job openings in the next 10 years.Of these 1 million jobs, 78 percent will require post-secondary education and 44 percent will be in trades and technical occupations. The action plan is designed to help give students and young people a clear and seamless path from school to the workplace.Programs such as these are great for our region as well as the rest of the province because it gives students an opportunity to learn about different experiences that are available to them in the trades.Advertisement There is a high demand for trades in Peace River North and programs such as Find Your Fit give our student’s immediate access to a range of careers close to home. Find Your Fit allows the students to test the skills that would be required for jobs such as welding, carpentry, heavy equipment operating, truck driving, accounting, and much more.Why is the BC Lions Skills for Life Summit note-worthy for our region?Because four of our very own students from Fort St. John and Fort Nelson will be taking part in the summit: Tate Hafner and Brandyn Sharron from Bert Bowes Middle School as well as Dawson Spence and Eagle Andersen from Fort Nelson Secondary School have been given the opportunity to attend this great education experience and the Grey Cup in Vancouver.I want to recognize these four students and congratulate them for the chance to take part in this event.Advertisementlast_img read more

first_imgMiller Matola, CEO of Brand South Africa; Thebe Ikalafeng, Chairman of Brand Finance Africa; Nicola van Ast, Senior Manager: Global Brand at MTN; Brian Gouldie, Chief Marketing Officer at MTNCELLPHONE companies lead the pack when it comes to the country’s most valuable brands. South Africa’s Top 50 Most Valuable Brands 2013 were named by Brand South Africa and Brand Finance Africa on 1 August, with MTN in pole position, followed by Vodacom.The leading brands are listed by financial valuation in South Africa; they are driving competitiveness and the nation’s reputation. Brand South Africa chief executive officer Miller Matola and Brand Finance Africa chairman Thebe Ikalafeng announced the leaders at a breakfast attended by representatives from some of the companies that make up the Top 10 Most Valuable Brands.Matola emphasized that the nominated brands had not only contributed to South Africa’s competitiveness but had also built civic pride. South Africans who believed in South Africa ensured the world believed in us, he said. “South African brands are playing a leading role in building the future while adding value for shareholders.”Brand Finance Africa valuation director Rupert Kemp outlined the Royalty Relief methodology used in the selection, which involved estimating the likely future sales that were attributable to a brand and calculating a royalty rate that would be charged for the use of the brand. This methodology considered three pillars, he said: brand support, for example marketing and distribution; equity; and, brand performance.South Africa’s Top 10 Brands 2013, he said, were:1.    MTN2.    Vodacom3.    Sasol4.    Standard Bank5.    Absa6.    Nedbank7.    Woolworths8.    First National Bank (FNB)9.    Shoprite10.    MediclinicMiller Matola, CEO of Brand South Africa; SASOL Group Corporate Marketing General Manager Vusi Cwane; SASOL Group Brand Marketing Manager Adolf Fourie; Brand Finance African Valuation Director Rupert KempKemp said Mediclinic was the highest upward mover in the top 10, moving up four places. The private hospital group is the sixth largest in the world and is now the most valuable health care services brand in South Africa.Shoprite had experienced huge expansion and had a presence in 16 countries outside South Africa, he pointed out, while FNB had built a strong brand that emphasized innovation. Woolworths had built its brand on innovation as well as high standards in food and clothing, said Kemp. Nedbank had steadily been growing its brand presence and had for the second time been voted Africa’s Socially Responsible Bank of the Year at the 2013 African Banker Awards.Kemp said banks on the whole were facing a challenging market exacerbated by up-and-coming newcomers such as Capitec claiming more and more market share. With Barclays increasing its stake in Absa to 62%, the local organisation faced important decisions. Standard Bank came in at number four, top of the banks in South Africa’s Top 50 Brands 2013, after a similarly tough year.At number three was Sasol, the fuels company, which Kemp said was a sterling achievement for a large B2B player. Innovation and building on trust and reputation were its formula, he said.South Africa’s two largest cellphone operators share the top two slots, with Vodacom coming in at number two. This was exemplary for a brand which had changed its identity to reflect parent company Vodafone while at the same time holding on to its heritage.MTN, at number one, was the only South African brand to be placed in the top 500 global brands, said Kemp. The company was constantly expanding and taking on new markets and could be seen to “fly the flag for South Africa in business”.Matola congratulated the winners, saying they were playing their part in building South Africa. “They are not only building value for shareholders but for the 50 million stakeholders” they had in South Africa. Their contribution would work towards building a great country brand. Brand Finance South Africa Most Valuable 2013South Africa’s 50 Most Valuable Brands Final August 2013last_img read more

first_imgStuff I Learned at Joe Lstiburek’s House, Part 1Duct Leakage TestingStatic pressure and flow are directly related to the electrical power required at the fan, which uses 80% of its energy to overcome static pressure and only 20% to create air velocity. This is why the SEER ratings of ductless minisplit equipment are much better than of the exact same model with ducted /cassette options. Ducts matter.The numbers here are infinitesimal – 0.011 PSIStatic dressure drop is commonly stated in terms of “inches of water column” (abbreviated “inAq” or “inH20”) or pounds per square inch (PSI). 1 PSI = 27.68 inH2O = 2.3 feet of head = 0.68 atmosphere = 6895 pascal (newtons per square meter).Pressure drop created by fittings in a length of duct is expressed as “equivalent duct length” — that is, the length of straight duct of the same cross sectional area that would create the same static pressure drop as the fitting in question.Air handlers are typically designed to operate against a static pressure of 0.3 inH20 or roughly 75 pascals or 0.011 PSI. The numbers here are infinitesimal compared to the 18 feet of head = 7.8 PSI numbers I’m used to dealing with in plumbing design.It’s important to understand static pressure because a 2½-ton (30,000 BTUh) heat pump needs to move 960 cfm to transfer that heat at a 30 degree temperature rise, but if the static pressure is too high, air flow will be reduced, limiting its ability to remove heat from the coil and transfer it to the home.As many as 80% of ECM motors use more power than the PSC motors they replacedA typical 1/3 hp PSC motor is designed to move 1,000 cfm at .30 inH2O while drawing 335 watts. At a higher static pressure of 0.6 inH2O, the same motor will deliver only 400 cfm, but will only draw 240 watts doing so, as the blower wheel blades simply recirculate an increasingly large percentage of their air, doing less work and thus drawing less power. A similar unit with an ECM blower can deliver 1,000 cfm at 0.3 inH20, drawing 225 watts; the ECM motor will still deliver 1,000 cfm at a higher static pressure of 0.6 inH20, but will draw 350 watts to do so. In other words, at a higher static pressure, the ECM motor continues to deliver 1,000 cfm (unlike the PSC motor, which delivers less air as the filters clog up). Gavin Healy commented that he has seen 4-ton and 5-ton gas furnaces with ECM blowers that were drawing 900 to 1,200 watts.David Hill believes that as many as 80% of energy-efficient ECM motors in HVAC systems actually consume more power than the PSC motors they replaced (but they do a better job of delivering the air across the coil and to the house).If the blower is only delivering 400 cfm due to that 0.6 inH2O static pressure, the ability to move heat is cut 60%, and that excess heat builds up in the cabinet and gets returned by the refrigerant to the compressor. The compromised equipment runs at high temperature/refrigerant pressure, returning more heat to the outdoor compressor. It runs longer and harder, with greatly reduced efficiency, both because it’s trying to heat refrigerant that is already hot and because the heat isn’t getting to the home to satisfy the thermostat.The “ductulator” only addresses 10% of duct lossesToo much attention in duct design gets focused on pressure losses due to duct friction. Part of the reason for this is that architects don’t give the HVAC crew enough room to take advantage of opportunities for better trunk line fittings and cabinet optimization, so duct length and sizing end up being the only variables they have control over.While flex duct that is pulled tight and well supported has less loss than slack or poorly supported flex, the friction component calculated using a ductulator (duct calculator) is not the primary villain here, at only 10% of losses. “System effects” of the furnace or air-handler cabinet, as well as coil and filter losses adjacent to the blower inlet and discharge, are second in importance at 30%. Duct fittings represent 60% of losses, and are therefore far more significant in actual practice.Evase opportunity and squirrel cage AikidoThe first opportunity for improvement is to give the air handler room to breathe on both the return and supply side of the cabinet. An “evase,” a piece of duct that increases in size and may change from rectangular to round in cross-section as it moves away from the air handler, helps bring the air out of the air handler in the same way that loud “megaphone pipes” on a motorcycle help pull exhaust from the manifold.When we look at how air escapes from a centrifugal (squirrel-cage) blower, we discover that it is moving at a different velocity depending on where in the exit cross-section it’s located. If we can give it three times the duct diameter to come to equilibrium before asking it to change direction, more of the energy in the fast air stream will be imparted to the slower air around the edges and close to the throat, and less will be lost to system effects.When choosing a cabinet for best air flow characteristics, we will be better served by equipment that pulls the air through the coil and exits through the blower rather than entering the cabinet through the blower and exiting through the coil.Don’t hit filters at an angle or with turbulent flowSimilarly, when we look at the static pressure impact of the filter, we discover that it is very much in our interest to hit the filter square on with the air stream rather than putting it in the wildly disturbed flow at the outlet of an elbow or angled to the stream as often happens when it’s on the intake of the air handler.The difference of the pressure curves of clean versus dirty filters is pretty shocking as well. In one example, an ECM system with a clean filter running at 0.2 inH20 at 1,100 CFM drawing 225 watts ran with a dirty filter at 0.5 inH20 at 1,100 cfm drawing 320 watts. If it had been a PSC motor on that air handler, the flow would have been reduced on the order of 40-50%.My takeaway here is that in homes with 100% of return air duct inside the conditioned envelope, it may be a good idea to install multiple air filters in the grilles where they have uniform face velocity across the full area of the filter and are readily accessible for service rather than in the mechanical room.Mind your elbows and wyes, especially in the trunk lineThe biggest thing we can do is look more carefully at elbows and take-offs in the trunk. When air exits a trunk at a right-angle fitting, the shape of the heel of the fitting is much less important than the shape of the throat. According to the ASHRAE Duct Fitting Database, an 8×14 elbow with a square heel and a square throat at 500 fpm air velocity has a pipe length equivalent of 39 feet. If you radius the heel, the equivalent drops to 36 feet. But if we leave the heel square and radius the throat, the equivalent length drops to 13 feet!What’s happening here? When the air passes that sharp throat, it creates an eddy — a pocket of turbulence just downstream from the throat (similar to the eddy you rest in while white water kayaking). Unfortunately, this eddy has the effect of reducing the usable pipe diameter and restricting flow. (In hot water distribution, this same eddy in the pipe mixes cold and hot together, increasing the amount of time it takes the hot water to push the cold out of the way and get to the fixture.) The square heel also gets clogged with turbulence, but in this case it converts it to a radiused heel with a bit more drag and doesn’t restrict cross-sectional area.My great-grandfather told me soThe way that elbows reduce flow in HVAC systems is similar to how they increase delivery times in hot-water distribution systems.This gives me an opportunity to share some images from my great-grandfather’s book, Experiments Upon the Flow of Water in Pipes and Pipe Fittings made in Nashua, NH 1892, in which he demonstrates experimentally that “for commercial elbows … little would be gained by making the radius of curvature more than about three times the corresponding pipe diameter.”Got “turning vanes”?That first elbow with a square throat and heel but with turning vanes installed at 1 1/2” OC has an equivalent duct length of 4 feet! The vanes break the air flow down into 1 1/2 inch slices, and each slice is directed individually in a way that effectively minimizes the size of that eddy.Increasing the size of the vanes and spacing them further apart reduces the effective length even more, but increases the difficulty of production and the potential for error in placement and for restriction if a vane comes loose over time. Using an elbow with smooth heel and throat and three full length vanes can reduce the effective pipe length to one foot!Start with a third-party HVAC designer and give the tin-knockers room to practice their craftGetting your HVAC contractor to adopt these practices seems likely to create a different type of static pressure. I have a hard enough time just getting mine to implement curved fin ceiling registers with interior supplies. But I’ve had pretty good success with hiring a third-party engineer to do my Manual J, S, and D calculations and then including floor plans and sections of the mechanical room on the prints (a.k.a the “funny papers”).HVAC installers quickly realize that their liability for the performance of the system is favorably impacted by bringing in a third-party engineer to take responsibility for the calculations and duct design. If you don’t calculate and draw out what you hope to achieve, there will be no place to begin discussion or collaboration.Start with the mechanical room, the trunk, and the longest runs. Focus on minimizing fittings overall, and (at least) putting 45 degree gussets if not radius’s on the throats of your take-offs and elbows. Pull the filters away from the air handler to a place with clean, undisturbed parallel air flow where they can be easily inspected and serviced by the homeowners. Design-in room for an evase on the supply side of the air handler.The opportunity to recognize and correct pressure drop parasites in bad duct design is before they are covered in drywall. In the Southeast where I live and build, we mostly rely on ducted HVAC systems for heating and (especially) for cooling. So when I attended the Westford Building Science Symposium in early August, I was very excited to sit in on David Hill’s presentation on HVAC systems, especially as Dr. Joe’s introduction paraphrased Samuel Clemens’ observation: “It ain’t so much the things we don’t know that get us into trouble; it’s the things we know that just ain’t so.”I’m especially interested in situations where new research is disproving assumptions behind accepted best practices, since these re-evaluations lead the industry to fine-tuning and improvements. David Hill’s presentation on duct design was full of these. The “take-aways” I got from this are:to examine the way we do duct take-offs and fittings,to place an “evase” between the fan outlet and the trunk or the split for the zone valves leading to the trunk in a zoned systems,to look very carefully at filter placement and the taughtness of flex duct, andto start doing all this in the design phase so we allow enough room to implement thoughtful duct design before the sheetrocker removes the opportunity for improvement.Pressure drop parasites rob equipment of efficiency and durabilityDuct systems contribute to bad HVAC performance by increasing static pressure and reducing air flow through the air handler. Air is only capable of carrying 1,000 BTUh per 31 CFM at the 30 degree temperature rise typical of heat pumps. (A gas furnace will typically run with a 30-60 degree temperature rise.) A 2½-ton (30,000 BTUh) heat pump with a 30 degree rise will need to move 31 cfm/Kbtu x 30 KBTU = 960 CFM. RELATED ARTICLES last_img read more

first_imgA day after the February 26 Balakot air strike, as Indian and Pakistani fighter jets were engaged in combat over the Naushera sector in Jammu and Kashmir, news filtered in of an Mi-17 crashing in Budgam. Six IAF personnel on board and a civilian were killed; among them was sergeant Vikrant Sherawat. With preliminary probe findings suggesting that the helicopter was shot down by India’s own ground-based air defence systems, Vikrant’s family feels cheated over being kept in the dark all these months — the IAF officers who brought his remains home had alluded to a “technical fault”.‘Facts hidden from us’At their house in Bhadani village here, Vikrant’s father Sri Krishan, 62, lies on a wooden bed, anguish writ large on the farmer’s face. “We had the right to know the circumstances in which he died. We don’t understand the politics. But it could be because of the elections that the facts were hidden from us. The way the Pulwama attack was politicised to seek electoral mileage, it seems the matter [friendly fire] was hushed up to avoid embarrassment to the government in election season,” says Mr. Krishna.Vikrant’s widow Suman says that a week after the incident, she had stumbled upon an article in a Hindi daily suggesting that the chopper was possibly hit by friendly fire. Kanta Devi, the late sergeant’s mother, says that a couple of his Air Force friends from neighbouring villages had also hinted at it, but advised her to keep mum in view of the political situation.Court of Inquiry The Court of Inquiry probing the incident is expected to submit its report in the next couple of weeks but until a definitive official version is shared with them, all Vikrant’s family has is information through the media.“News reports suggest the senior-most officer among those guilty is being transferred as punishment. I demand that all officers responsible for it be given strict punishment,” said Ms. Devi.last_img read more

first_imgMuzaffarpur AES deaths: SC asks Centre, Bihar to explain steps to curb outbreak The death of children in Muzaffarpur in Bihar due to acute encephalopathy could have been prevented had a health awareness campaign been conducted and correct information provided to the families, said an Indian Medical Association (IMA) study team, which released its ground-report on Monday.The team said that it can be reasonably concluded that the prevailing heat and humidity, together with malnutrition, contributed substantially to the deaths. Dehydration, hypoglycaemia and the heat syndrome too played a significant part.“Awareness is key. Tepid sponging and correction of dehydration and hypoglycaemia can start right from home. A package programme focussed on health awareness, free meals to children, especially at night, and public availability of ORS (oral rehydration solution) may be simple interventions which may prevent further deaths of this scale,” noted the report.Also Read  The Association said going by its observations, there are no definite conclusions that can be made about the aetiology of the syndrome as of now.“The current problem seems unlikely to be an infectious cause with the present evidence and we feel that litchi consumption cannot be attributed as the major factor, as even infants have been affected. The persistence of very high atmospheric with temperature humidity through out the day and night without fluctuations might be causing a heat syndrome in children,” noted the report.It added that reduction in body temperature with tepid sponging, increased fluid intake and adequate food intake may prevent this syndrome. While affected children have to be given IV dextrose for correction of hypoglycaemia to prevent significant brain injury, foolproof scientific, epidemiological study and follow up among children who survived in previous episodes (in 2014 and 2015) should be done systematically.Measures to uplift the living conditions of the affected population should be undertaken as an immediate package programme, noted the Association.last_img read more

first_imgThe Commonwealth Games (CWG) in Delhi plunged into grave uncertainty on Tuesday over “unlivable” conditions for athletes at the Games Village. Complaints from advance teams of several countries were followed by Commonwealth Games Federation CEO Mike Hooper flatly dubbing the Village as “filthy” and warning that “time had run out”. Village filthy: Hooper”We are disappointed with the condition we find ourselves in. We came to know about this when we paid a visit (to the Village) on September 15,” Hooper said at a press conference. Fennell asks govt to take immediate steps to fix the condition of Games Village’s residential zone.”Cleanliness and hygiene are great concerns. Electricity and plumbing problems, if any, too need to be addressed. We need to put capable resources and staff to fix the issues tower by tower,” he said.  “The Village is filthy. One can’t occupy the rooms. There is building dust and rubble and the toilets are not working. Reports of excrement being found are true,” Hooper said without mincing words. “The Village is supposed to provide the athletes the right environment to prepare for the events. But at the moment we cannot say that’s the case,” he said. “The promises made have not been kept. Time has run out. Hopefully we will see significant action to fix the problems,” Hooper said. CWG faces call-off threatEarlier, New Zealand’s CWG chef de mission Dave Currie raised an alarm and even suggested that the Games could be called off. “If the Village is not ready and the athletes can’t come, obviously the implications of that are that it’s not going to happen,” Currie said.  “In the timeframe that is left, unless there is tremendous effort and energy and problem-solving ability to get it done, I think it’s going to be extremely hard to get across the line. They’ve got a little bit of time but it’s kind of two seconds to midnight really,” he said. Fennell shockedCommonwealth Games Federation president Michael Fennell too sent a hard-hitting letter to Cabinet Secretary K.M. Chandrashekar on the state of the Games Village. Fennell wrote that he was shocked at the condition of the residential zone and that many contingents had complained about it.  With less than two weeks to go for the sporting extravaganza and the athletes scheduled to arrive in Delhi on Thursday, Fennell expressed doubts over the readiness of the Village. He said the complex had been “seriously compromised”.  NZ, Canada, Scotland complainFennell’s letter came after New Zealand, Canada, Scotland and Ireland strongly protested against the quality of accommodation at the Village. The contingents asked the CWG Organising Committee to put their officials and athletes in hotels if they could not set the Village apartments right.  The complaints included problems with hot-and-cold water supply, doors and windows as well as stained toilets. No pullouts, says OCBut the CWG Organising Committee expressed surprise. CWG Organising Committee CEO Jarnail Singh admitted to the complaints but said no country was pulling out.  “The complaint came three days ago. The teams of the respective countries will be shifted to the older block in the CWG Village,” he said. Singh said more than 700 workers were working overtime at the new block ever since the complaints had been made.advertisementlast_img read more
