On ISSA, schoolboy football and unruly behaviour

first_img dangerous behaviour This reprimand is so numbing in its inappropriateness, that it boggles my mind. Perpetrators of such rank indiscipline and potentially dangerous behaviour should not be allowed access to further games involving that school. That is a given, even if it means that ISSA will not be able to collect gate receipts that can offset the cost of putting on the game. At some stage, Jamaicans must realise that if the cost of unruly and dangerous behaviour is far less than the reward for unruly and dangerous behaviour, then no amount of divine intervention will curtail future similar occurrences. Giving a ‘bly’ If the people who murder our fellow citizens and rape our women and children thought for a moment that being caught and punished was a reality instead of the present 80% chance that their identity will remain unknown, or if by some stroke of luck they are indicted, then a good lawyer and the ability to have prosecution postponed year after year will almost guarantee no punishment. It is the little things that matter. The New York City mayor and police force recognised some years ago, that if you start by fixing the broken windows and prosecuting anyone who breaks the law (riding on the sidewalk for example), crime statistics will dramatically be reduced. This attitude of giving a ‘bly’ only serves to incentivise miscreants. After the weeping and wailing of those justifiably severely punished for ‘stoning the ref’, such incidents will cease, thus improving spectator comfort, sending a message to the children who attend the schools and eventually improving revenue as more supporters and spectators will feel that their safety and the spirit of sport are in good hands. Football in particular, and sport in general, is a part of the holistic education of our children and our people. It must never be the ‘reason’ to go to school! The school teams are now sponsored (some more than others) and it seems as if the other aspects of school life are now on the back-burner. The playing surfaces remain woeful and the prevailing drought conditions are definitely not helpful. In the ISSA-controlled schoolboy competition, night games are being introduced for what can only be described as ‘revenue enhancement’. I suppose it matters not if children coming home from night games are exposed to increased danger from ‘evil’, as long as ISSA collects at the gate, (“ah-nuh-nutten”). Already there are reports of coaches of “small” schools complaining bitterly of the poaching of talented youngsters by affiliates of “big” schools, despite the welcome efforts of the Ministry of Education to minimise this nefarious practice. The administration of activities in any civilised society depends on the strict adherence to agreed rules by the participants. Rules that are broken or ignored will only serve to incentivise those looking on to “act accordingly” if the cost of breaking a rule is far less than the benefit derived from adhering to the rule. It now seems (to me) that if the supporters of a school do not agree with a referee’s decision in a closely contested game, then by all means “stone the ref” and cause the game to be abandoned. The team was going to lose the match anyway, but now the ref (or any other authoritative figure) will be well aware that “when-it-comes-to-this-school… no bother mek we lose!” .(stoning the ref) be rewarded by a loss of points and “don’t do it again.”last_img read more

Life Influences Dating Method

first_imgThe rate of calcium carbonate precipitation can double if microbes are present, says an article in PhysOrg.  Scientists studying hot spring deposits in Yellowstone made this “surprising discovery about the geological record of life and the environment.”  The article adds, “Their discovery could affect how certain sequences of sedimentary rock are dated, and how scientists might search for evidence of life on other planets.”    The travertine terraces at Mammoth Hot Springs in Yellowstone can grow millimeters per day.  The precipitation can actually “more than double” when microbes are present, the article said.  Calcium carbonate is the most abundant mineral in the rock record.    The scientists believe that inferences about the presence of life can be drawn from studying the rate of deposition.  “Separating biologically precipitated calcium carbonate from non-biologically precipitated calcium carbonate is difficult,” however.  Inferences about life would also require independent knowledge about the rate of deposition.  They believe they can tease this information out from the chemistry, based on “the environmental and ecological context of the rock being studied.”The important observation here is that previous trusted assumptions about most common sedimentary rock were off by more than a factor of two.  What other assumptions are still unquestioned that will be overturned in the future?  Other questions: What will this do to cave formation dating methods?  Will they change the textbooks within the next decade?  How can they rightfully infer the presence of life from a precipitation rate on a planet where no life has been found, when other unknown factors could influence the rate?  How come geologists never apologize for the misinformation they spread?(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Using Total Effective Length in Duct Design

first_imgRELATED ARTICLESThe Fundamentals of Rigid Duct DesignThe Two Main Reasons Your Ducts Don’t Move Enough AirAll About Furnaces and Duct SystemsSaving Energy With Manual J and Manual DKeeping Ducts IndoorsReturn-Air ProblemsSealing DuctsDuct Leakage Testing Today I’m going to explain an important concept in one of the most popular ways of doing duct design. I’ve been writing a series on duct design over at my blog and began with a look at the basic physics of air moving through ducts. The short version is that friction and turbulence in ducts results in pressure drops. Then in part 2 I covered available static pressure. The blower gives us a pressure rise. The duct system is a series of pressure drops.We can divide the pressure drops into two categories: those resulting from the ducts and fittings and those resulting from all of the components that aren’t ducts and fittings (e.g., registers, grilles, filters…). When we subtract the non-duct/fitting pressure drops from the rated pressure rise (total external static pressure) of the blower, we get the available static pressure. That’s the total pressure drop we have available for the ducts and fittings and is what sets our duct pressure budget.What we want to get out of this in the end is the proper duct and fitting sizes. We have a certain amount of available static pressure to use up. If our ducts are too small, we can end up with either too little air flow in the case of a fixed-speed blower (PSC, which stands for permanent split capacitor), or we get the air flow but use too much energy with a variable-speed blower (ECM, which stands for electronically-commutated motor). The first step in finding the proper duct and fitting sizes is to find the total effective length (often called equivalent length), the topic of today’s article. What is effective length?Length is length, right? Why do we need something else called effective length? The answer lies in fittings, those duct components that allow you to take air out of a trunkline, split a single duct into two runs, turn the air, and more.For straight duct sections, pressure drop depends only on the length. Well, that’s the idea anyway. If we use flex duct and don’t pull it tight, the pressure drop will be greater than if it were pulled tight. Texas A&M did a study on the effect of flex duct not pulled tight and the results are astounding. In my article on this research, I showed from their results that a 6″ duct moving 110 cfm when pulled tight will move only about 70 cfm with 4% linear (longitudinal) compression and about 40 cfm or less at 15% compression. (I’ll write more about the effect of different duct types in the HVAC design process later in this series.)For our purposes here, I’m going to assume that the ducts we’re using are either rigid metal or flex pulled tight. ASHRAE now has a duct calculator with options for 4%, 15%, and 30% longitudinal compression, but that’s not for use in designing duct systems. It’s to show how bad existing systems are if the flex isn’t pulled tight or to scare installers into pulling it tight.So, we’ve got straight sections of duct with their pressure drops depending on the actual length. And then we’ve got fittings. Each fitting — whether it’s splitting the air flow, reducing the duct size, or turning the air — will cause a pressure drop. In the duct design process, however, it’s more convenient to categorize these pressure drops by the length of straight duct run that would create the same pressure drop. And that, my friend, is the definition of equivalent length.But wait, you say! You were talking about effective length and now you’re talking about equivalent length. What’s going on here? ACCA’s Manual D uses both terms, although without clearly distinguishing them. From the context, though, here’s what I’ve surmised: The effective length is the combination of actual lengths of straight duct and equivalent lengths of fittings. Most people use the term equivalent length for both, though.Adding up all the lengths and equivalent lengthsBefore sizing a duct system, we have to lay out all the ducts. Below you can see an example of one we did recently. It shows the duct layout with all vents, fittings, air flows, and duct sizes. To find those duct sizes, the software we use (RightSuite Universal) calculates the effective length of the most restrictive run. From the return grille to the supply register in that run, it adds the lengths of the straight runs and the equivalent lengths of all the fittings.Each fitting we choose has an effect on the pressure drop and total effective length (TEL). We can look them up in tables, like the one below showing equivalent lengths for various elbows.The main variables we have to work with for this fitting type are:Radius of the turn (R)Diameter of the duct (D)Number of piecesRound or ovalWhen we choose fittings, we pick them based on what’s commonly available at HVAC supply houses. We also go a little conservative here because we’re doing third party HVAC design and don’t have control over the installation. For example, most of the elbows used in actual duct systems have 4 or 5 pieces. We often choose a 3 piece elbow in our design, though, because it gives us a little slack in the design. If the installer uses the 4 or 5 piece elbow instead, with 5 feet less equivalent length, the actual duct system will be less restrictive than the designed duct system, at least in that part.The total effective length (TEL) is the sum of all those fitting equivalent lengths plus the lengths of straight duct. If you’re doing it by hand, you have to go through the process for every single duct run. Then you choose the one that has the greatest total effective length. You do NOT use the sum of all the ducts and fittings.The last image below is a screenshot from RightSuite Universal showing the total effective length in one of our designs. The lengths of straight sections of duct add up to 36 feet for the supply side and 13 feet for the return side. The fittings add up to 290 feet and 85 feet respectively. This is typical. Fittings dominate when it comes to using up the available static pressure, so you have to choose them carefully. Just take a look at that table of elbows above. If you choose well, you can be at 10 or 20 feet of equivalent length. If you choose that smooth mitered elbow, however, you end up with 75 feet.The next stepOnce you lay out your ducts and choose your fittings, you have a total effective length. But here’s a little caveat: Those equivalent lengths for fittings depend on the velocity of the air, too, and it’s not a linear relationship. There are corrections for that effect, which, as far as I know, aren’t currently built into the software.To summarize:The blower creates a pressure rise to move air through the ducts.It’s rated for a certain amount of air flow at a specific total external static pressure.The ducts, fittings, and other components cause pressure drops.Subtracting the pressure drops for all the things that aren’t ducts or fittings from the total external static pressure yields the available static pressure.The available static pressure is the pressure drop budget you have to work with when designing the ducts.Each fitting has an equivalent length that equates its pressure drop to an equivalent amount of straight duct.When you add up the equivalent lengths of all the fittings and then add that number to the length of the straight sections in the most restrictive runs in the return and supply ducts, you find the total effective length (TEL).The next step in designing a duct system would be to take your available static pressure and figure out what friction rate you have to work with in sizing the ducts.

Team USAs World Baseball Classic Championship Didnt Come Easy

DATEROUNDTEAMALL-TIME SRS RANKUSA’S RESULT 3/22FinalPuerto Rico5thW 8-0 Team USA’s path to the championship Team USA finally did it. Buoyed by a tremendous pitching performance from starter Marcus Stroman — who carried a no-hitter into the seventh inning — the United States routed Puerto Rico 8-0 in Wednesday night’s title game of the World Baseball Classic, securing America’s first-ever championship at the event.Going from mediocre (they went into 2017 with a 10-10 all-time record in the tournament) to championship worthy wasn’t easy for the U.S. Although the American roster was stacked with major leaguers, the team once again found itself facing elimination after losing to Puerto Rico last Friday. Keeping its tournament hopes alive meant beating the Dominican Republic — the second-best team in WBC history by my calculations,1I used the Simple Rating System to rank every team in WBC history. (and one that had roared back to beat the U.S. a week earlier) — in a do-or-die qualifier, then beating Japan (the greatest team in WBC history) in the semis, and then turning the tables in a rematch with Puerto Rico (who were undefeated and playing as well as any WBC team ever).Talk about a difficult path to a championship: 3/11Round 1Dominican Republic2ndL 7-5 But the U.S. persevered through it all, and now they are WBC champions.
