first_imgDear Editor,I have a question and I would appreciate an answer from whoever wishes to educate me about this issue. My simple question is which political party will form the Government if after the next election, the two major parties each end up with 32 seats and another party with one seat?Ok. This number, 32, has been featured too much recently. What if the two major parties each end up with 30 seats and the other parties with a total of five seats? Which party will form the Government?Editor, pity my simplicity for asking this question which might be totally irrelevant.Regards,Wesley Kirtonlast_img read more


first_imgWith the downsizing of the sugar industry leaving over 7000 workers without jobs, Guyana’s employment rate could see a dramatic increase. This is according to outspoken political commentator and economist Ramon Gaskin who on Wednesday said Government has no comprehensive policy for job creation. His comments are being made as the Guyana National Bureau of Statics (GNBS) gears up to release its unemployment numbers for 2018, which will serve as a marker to the economic status of the country. The quarterly Labour Force SurveyOutspoken political commentator, Ramon Gaskinfor July to September 2017 had revealed that the unemployment rate for persons aged 15 and above was 12 per cent, with the situation for women being substantially worse than that for men.At that time, thousands of now dismissed East Demerara, Rose Hall and Skeldon sugar workers were employed up to December 31, 2017 and taking into consideration of their contention relating to inconsistent employment, Gaskin’s estimation of an increased unemployment is likely to reflect the reality.However, as the official numbers are being finalised, Gaskin from his assessment of the economy, intimated that youth unemployment is also significant with reference to the magnitude of persons present at the recent job fair at the soon to be opened MovieTowne Guyana establishment earlier this week.“The unemployment rate is quite high, there are no jobs in this place; people are coming out of school and are looking for work; nobody opening any jobs, besides MovieTowne; there are no other jobs available…the Police, Army, public service are employing people but in the Private Sector there are no jobs,” Gaskin suggested.No concrete policyIn this light, he was questioned on the need for a shift in Government policy should the employment drop. Gaskin thereafter indicated his dissatisfaction with the presentation of Finance Minister Winston Jordan’s 2019 Budget wherein he contended that there was no concrete policy for job creation.“The Government has no policy for job creation; the Finance Minister Budget had no provision for job creation – he talked about entrepreneurship, training people in the interior and small business enterprise programme but there are no jobs available for employees. He cannot tell you where jobs are being created,” Gaskin pondered. Moreover, he indicated that the public service payroll has increased, saying that large contingents of persons are seeking employment with the State.” It’s packed up with people; all of them going there to see if they could get lil work.”Gaskin also related that Chinese-contracted building projects such as the one near the Chinese embassy have a majority of foreign workers in addition to the Cheddi Jagan International Airport (CJIA) expansion Project. He called for more locals to garner employment on such projects. After seven years, the CJIA expansion remains incomplete due to several delays.The 2017 survey was done from a total population of 550,831 – persons 15 years and above, with some 72.2 per cent living in urban areas. From this figure, only 271,068 comprised the total employed population during the time of the quarterly survey, with males having accounted for 166,873 and females 104,195. The survey’s findings had revealed unemployment among women was 15.3 per cent and among men 9.9 per cent. The youth unemployment rate among 15 to 24-year-olds was almost twice that of adults, with 21.6 per cent. Young women had seen 28 per cent of them being unemployed.The employment rate for persons 15 and above was 49.2 per cent, with 62.1 per cent being males and 36.9 per cent being females. It had been also noted that the percentage of employed people in time-related underemployment was 4.2 per cent, with 72.2 per cent of the underemployed being based in urban areas.The survey also found that 28.4 per cent of the labour force is underutilised, while between 48.3 per cent and 52.6 per cent of the persons employed hold informal jobs.Prior to the 2017 estate closures, the Wales Sugar Estate was shuttered in December 2016 and many workers in that community say they have faced a decline in finance. Given the decrease of jobs in rural areas over the two-year period, it remains to be seen what the numbers in the 2018 survey will reflect.last_img read more

first_img“This year, with the exciting innovations introduced by the PSL and the new sponsor MTN, I feel that the competition will be fiercer than ever before, and I am certain that there are no favourites,” he said. FixturesIt kicks off on Friday 8 August at the Johannesburg Stadium, where Orlando Pirates will take on PSL champions SuperSport United. The Buccaneers have had ample opportunity to find their pre-season legs in the Vodacom Challenge and the Telkom Charity Cup, which they won at the weekend with a 1-0 win over Kaizer Chiefs. “The eight winners from each of the matches will then go through to the final, where they will compete for the ultimate prize, and to be crowned the ultimate MTN 8 Wafa Wafa fan.” The MTN 8 Knockout will feature South Africa’s top eight clubs doing battle for a lucrative R8-million winner-takes-all prize. The tournament’s catch phrase will be “Wafa Wafa!” which, roughly translated, means “last man standing”. Interestingly, the competition draw favoured all four Gauteng clubs in the competition with home games. “The most passionate fans at each match will be selected to take part in a half-time competition, with the crowd voting for the winner,” Verkade said. 5 August 2008 Another two quarterfinal clashes take place on Saturday 9 August, with Moroka Swallows facing Ajax Cape Town at Olympia Park and Kaizer Chiefs tackling Santos at Loftus Stadium. Chiefs, like Pirates, have enjoyed plenty of pre-season action and are, on the evidence so far presented, an improved outfit over last season. ‘Memorable matches’“Since the inception of the Top 8 in 1972, we have seen the birth of many legends and some truly memorable matches,” PSL chairman Irvin Khoza said in a statement. center_img The Premier Soccer League has announced another big windfall with MTN committing R400-million over five years to the sport. The cellular communications giant has also taken over the title sponsorship of the Top 8 knockout tournament. The prize money is significantly improved over last year’s figures, which saw Mamelodi Sundowns, as winners, taking home R1.3-million and runners-up Orlando Pirates pocketing R750 000. The format gives the clubs and players extra motivation to win, but each team will receive R800 000 simply for participating. The first leg of the semi-finals will be staged the following weekend, on 16 and 17 August, with the second leg fixtures scheduled for 23 and 24 August. World Peace Day, 21 September, will be the day of the final. ‘Ultimate football supporter’MTN spokesman Pieter Verkade urged fans of the top eight clubs to become involved in the competition. “Just like the teams, we encourage the fans to go all out and demonstrate their passion for the game and their club, to determine who the ultimate football supporter of the MTN 8 Wafa Wafa competition will be. “As the only African global sponsor of the 2010 Fifa World Cup South Africa, MTN has shown its passion for football,” Khoza said. The last of the quarterfinals sees Mamelodi Sundowns in action against Free State Stars at the Super Stadium on Saturday 10 August. The Brazilians will want to make amends for their early exit from the Telkom Charity Cup, and will also want to show that they are better than their fourth place in the 2007/08 PSL season.

first_imgThe task for WUFIWhen heat, air, and moisture move through materials, assemblies, and enclosures, they do so with great complexity. Moisture, for example, can move via any of the mechanisms listed in the table below (see Image #2). Also, things are always changing with time, of course, and a flow usually depends on the direction taken through an assembly as well. Properties change depending on which way you go. (The fancy physics word for this is anisotropy, and it’s where the amazingly fun del operator, ∇, comes into play.)WUFI models the flow of heat and moisture through an assembly. It can do a pretty good job with isotropic (uniform in all directions) materials or assemblies… if you get the inputs right. What that means is that you can get pretty good results for one-dimensional flows in the field of an assembly, such as a wall or ceiling. Last year I wrote about WUFI 1-D and showed that it can tell you how likely a material is to grow mold based on the moisture accumulation or drying over time.The equations that WUFI attempts to solve are shown below (see Image #3). The software does so numerically, and it requires the user to put in a lot of information about the assemblies being modeled. The solutions show heat and moisture travel across an assembly over time.According to Joe, when WUFI came across the Atlantic from Germany, it didn’t do a good job of incorporating air flow or rain. Now the software does a better job with them, getting closer to accurate modeling of the transport mechanisms shown in the table below. You still have to know how much wind-driven rain or air leakage to model and pick the correct weather location, but “WUFI is ready for prime time,” Lstiburek said. Allison Bailes of Decatur, Georgia, is a speaker, writer, energy consultant, RESNET-certified trainer, and the author of the Energy Vanguard Blog. Check out his in-depth course, Mastering Building Science at Heatspring Learning Institute, and follow him on Twitter at @EnergyVanguard. A lesson in water“The three biggest problems in buildings are water, water, and water.” Gus Handegord said this a long time ago, and it’s still true. (Now I know who to give credit to for the variation on this quote I used in Matt Risinger’s Summer Camp video.) What happened to The Igloo Chronicles, Part IV?If you’ve been following the debate from a distance over the past two years, you might think Joe and Achilles hate each other. Nothing could be further from the truth. They’ve worked together for a long time, and Joe talks admiringly about all the hours Achilles put in to read and comment on his doctoral dissertation. I got to spend time with them at the 2013 North American Passive House conference, and it’s clear that these two men like and respect each other. (By the way, the blonde blur in Image #4 below is Betsy Pettit, Joe’s wife and business partner at BSC.)But I just wish they’d continued the igloo theme. I don’t think either of them mentioned igloos once during the Expert Session on WUFI (although Achilles did mention candles3), so they killed my idea of calling this article, The Igloo Chronicles, Part IV. Dr. Joseph Lstiburek started it in 2012 when, in his keynote address at the Passive House conference, he said igloos were the first passive houses and you don’t need WUFI,1 the hygrothermal modeling tool, to design and build a good house. Dr. Achilles Karagiozis, one of the leading proponents of WUFI, struck back in a presentation at the 2013 Westford Symposium on Building Science. In it he described a scenario in which Joe was in a helicopter crash in Alaska and had to build an igloo to survive. At the Passive House conference this year, Achilles expanded on that same topic.Last week at Building Science Corporation‘s (BSC) annual Expert’s Session, the two of them presented on the same day in a daylong seminar on hygrothermal modeling. And as a bonus, Kohta Ueno of Building Science Corporation presented on his work on the modeling and monitoring of embedded wood joists in insulated masonry walls. Here’s what you missed if you weren’t there. Lstiburek began his part of the hygrothermal modeling session with this quote and a beautiful explanation of the fundamentals of building science, the laws of thermodynamics, and the behavior of water. Although most of us are thinking about the flow of turkey and pumpkin cheesecake this week, it’s the flow of HAM — heat, air, and moisture — that’s of great concern in building science, and Joe showed how it works.The central focus was on water, which, all by itself, is the three biggest problems in buildings. According to Joe, 80% of all construction problems are related to water.The lesson covered the fundamentals, but Joe really shone when discussing the movement of water through porous media and through assemblies. He discussed the four — yes, four — phases of water.2 Liquid, gas, and solid are well known, of course, but adsorbed water behaves differently from any of those three.The difference between adsorption and absorption is an important one. For water in porous materials, absorption would be liquid water filling the pores. Think of a sponge absorbing water. Adsorption would be just a few layers of water molecules lining the surfaces of the pores. Adsorbed water moves differently from water in the liquid or vapor phases, and that has significant implications for building science.After explaining the basics, Lstiburek went into the details of the different mechanisms that get water moving through materials and assemblies, as shown in the table below (see Image #2), taken from the presentation slides (which you can download from the BSC website). He covered vapor pressure, concentration, Kelvin’s equation, contact angle, and surface energy and made it all make sense.It was a really great presentation, and if you haven’t seen Dr. Joe do this, I certainly recommend it. A lot of what he did here was part of his two-day Building Science Fundamentals class. The doctors’ advice on the limitations of WUFIBoth Dr. Lstiburek and Dr. Karagiozis cautioned the audience on the limitations of WUFI. Karagiozis used the example of him trying to give his presentation by reading notes off a regular sheet of paper held up by Lstiburek all the way in the back of the room. No matter how good your eyes are, you’re not really going to be able to read that piece of paper very well.Karagiozis also said it’s important to use the transport properties of the actual material that’s going to be used in the assembly. You can’t use generic properties because density, permeance, and other properties vary from one product to another. Extruded polystyrene (XPS) from Owens Corning, for example, doesn’t have the same properties as XPS from Dow.Lstiburek’s statement about hygrothermal analysis increasingly being included in contracts was followed by a big caution sign. Mechanical and structural engineers, he said, are most likely to be the ones who have to do the modeling, but if they don’t know the tricks of using WUFI, they’ll get the wrong answers.For example, he told us about a case in Houston where an engineer ran WUFI and found that the building’s walls were getting wet from interior water vapor. So the engineer specified a vapor barrier beneath the drywall. “When you get the wrong answer, you shouldn’t be doing this,” Joe said. What he meant is you shouldn’t be doing this when you don’t recognize that you’ve gotten the wrong answer.In addition to what Joe and Achilles said, Kohta Ueno presented what he’s learned so far in a Building America project they’ve been working on at BSC (which you can download from the BSC website). They’ve been modeling and monitoring the heat and moisture flows in embedded wood joists in insulated masonry walls, a fairly common construction. What he concluded was that using a 1-D model on a 3-D hygrothermal problem is not recommended, largely because of the great number of inputs and variables. He said you could spend a lot of time on modeling a problem like this, but it’s probably not very useful. When should you use WUFI?According to Joe, WUFI definitely has its uses. And those uses are in assemblies that don’t have a track record, like superinsulated, supertight Passive House projects. With R-40 truss walls or R-60 insulated rooflines, the margin for error is smaller, and WUFI can provide valuable insights into how those assemblies might work. You still have to follow up with monitoring the actual performance, but the modeling might be able to help you avoid costly mistakes.“The tool is phenomenal,” Joe said, but he wants to help reduce the mistakes people make by using WUFI. To that end, BSC is working on materials to help users learn what kind of tolerances they’re dealing with. The BSC team is putting together lists of inputs that will produce certain results so users get a feel for the inputs and the outputs.“I’m hoping two-thirds of the modeling that’s being done now won’t need to be done,” said Lstiburek, “and the modeling that’s needed is done correctly.” The uses of WUFIWhen you use WUFI and get results, you can learn a lot about how an assembly or collection of assemblies might behave. One thing you can do is to model the performance of a new type of wall assembly to see if it will dry adequately.You can also model the performance of a whole enclosure as a collection of assemblies. This is what WUFI Passive does. PHIUS allows Certified Passive House Consultants to use either the PHPP or WUFI Passive to certify Passive House projects. This version of the software incorporates the Passive House requirements, so it gives you a dynamic look at what’s happening with the assemblies as well as the conditions inside the enclosure and whether it passes or fails.Karagiozis said a hygrothermal analysis tool like WUFI is needed to address ASHRAE’s design methodology. We didn’t need it before, he said, because buildings were more tolerant of mistakes. Now, though, we need it because of:Enhanced comfort requirementsEnergy conservationNew materialsWe can use WUFI, Karagiozis said, to design for increased drying performance, better water management, and more forgiving systems.According to Lstiburek, hygrothermal analysis is being included in more and more construction contracts these days, too. But is that a good thing? RELATED ARTICLES WUFI Is Driving Me Crazy A Brief Introduction to WUFI, in 5 Easy PiecesMakin’ WUFI Footnotes1. WUFI stands for Wärme- Und Feuchtetransport Instationärs, which translates literally (according to Google’s translator) as Heat and Moisture Transport Unsteady.2. Since I was trained as a physicist, I thought the fourth phase would have been plasma the first time I heard someone talk about the four phases of water, but plasma doesn’t really come into play in building science, unless you’re working on a physics lab or nuclear fusion reactor.3. In his earlier WUFI talks, Achilles described a scenario with Joe burning candles to try to stay warm enough inside his makeshift igloo to keep from dying after his Alaska helicopter crash. At the PHIUS conference this year, he also told the audience that Joe loves candles, especially scented ones, so if you want to be his friend, just give him a candle. So I gave him one last week. You should, too.last_img read more


first_imgWhy does your hatchback, sedan or SUV give you a mileage different from what the car manufacturer claims under test conditions?This question made a Mizoram University professor and a research scholar invent a measuring device that yields a near-accurate mileage of a car per litre of fuel. Theirs is one of 25 patents applied for by teachers and research scholars of the university at Tanhril, about 15 km from State capital Aizawl.“Accurate knowledge of automobile mileage is crucial as it is an important performance index parameter of a vehicle during on-road operation. But the mileage achieved by a vehicle during actual road transport applications generally deviates from the manufacturer specifications under controlled conditions for a few driving cycles,” Hranghmingthanga, a professor in Mizoram University’s Department of Physics, told The Hindu.He and research scholar L. Lalnunthari worked on a mechanism that, unlike laboratory measurement, took into account factors such as road condition, driving style, traffic congestion, fuel quality used, gradients, and load on the vehicle.The inexpensive device entailing a digital multimeter, a pipe, and a calibrated fuel container was tested on an 800 cc petrol hatchback under conditions experienced by drivers on the road. “The margin of error in measuring the accurate mileage in kilometres per litre was 10%,” said Mr. Hranghmingthanga said.The device can be used for measurement when the car is stationary. “We can do the reading before starting the engine and after the ignition is switched off at the end of a trip,” said Ms. Lalnunthari.The duo declined to get into the details of their invention expected to be elaborated upon in a science journal soon. “It would suffice to say that it is intended to help vehicle manufacturers give the true average mileage and possibly work on more fuel-efficient engines,” said Mr. Hranghmingthanga.“Our university has had a tremendous year with applications filed for 25 patents by various departments. We have also attracted projects worth more than ₹40 lakh, and our aim is to be a topper among higher education institutes in the country,” said Mizoram University Vice-Chancellor K.R.S. Sambasiva Rao said.last_img read more


first_imgAll India Congress Committee’s Punjab in-charge Asha Kumari on Tuesday sought a report from the party’s State unit over the face-off between Chief Minister Amarinder Singh and his Cabinet colleague Navjot Singh Sidhu. Mr. Sidhu is under fire from his own party leaders after during electioneering he questioned as to why no FIR was lodged against the Badals for the desecration of religious texts in 2015. “We seek a report on every event, and in this issue too a report has been sought from the PCC,” Ms. Kumari said. She said the State party chief Sunil Jakhar, who is seeking re-election from Gurdaspur, will give the report once he is free from the election process after the declaration of the results.Captain Amarinder on Sunday had accused Mr. Sidhu of “damaging” the party in the State and suggested that he wanted to be the CM himself.Support for CM Meanwhile, more party leaders came out in support of the Chief Minister. “Amarinder Singh is an undisputed leader of Punjab. There are many facets to his personality,” said former Union Minister and party leader Manish Tewari. He praised Capt. Amarinder as a “protector of Punjab’s waters”, a writer, an able administrator who has a mass appeal. Jails Minister Sukhjinder Singh Randhawa also hit out at the Local Bodies Minister, saying, “Making such a statement during elections meant directly helping the Badals.” He added that Mr. Sidhu should know that it was Amarinder Singh who fought against the Badals and ensured the Congress victory in the 2017 Assembly polls. “In the 2017 Assembly polls, the Congress came to power in Punjab with an overwhelming majority as people voted in Amarinder Singh’s name. The party high command is with the Chief Minister. Our party has never tolerated indiscipline,” Mr. Randhawa said.Mr. Randhawa also alleged that when Mr. Sidhu’s wife, Navjot Kaur, was a BJP MLA, she never spoke on the desecration issue.‘Unease in ranks’ Union Minister of State for Housing and Urban Affairs Hardeep Singh Puri, who is the BJP’s Lok Sabha candidate from Amritsar, took a jibe at the Congress, saying, “All along the campaign, one could sense unease in their ranks.” “Now the cat is out of the bag,” he tweeted.last_img read more
