Bielsa extends stay as Leeds United boss

first_img Asked why there has been a delay in agreeing a new contract, Bielsa said: “It isn’t of importance. I have been working 100 per cent since we were promoted. “The club, the fans, the players, they all deserve to be playing in the Premier League.” Leeds could not have picked a tougher first game back than a trip to Anfield, where Liverpool are unbeaten in the league since April 2017. Bielsa, who has brought in defender Robin Koch and forward Rodrigo Moreno during the close season, has talked up opposite number Jurgen Klopp’s managerial achievements ahead of this weekend’s showdown. Bielsa’s deal expired at the end of 2019-20 but Leeds have been working hard to agree fresh terms with the Argentinian, who is considered one of the most influential coaches in the game. There has still been no official announcement on a new deal with two days to go until United’s trip to champions Liverpool, but Bielsa has assured fans he is going nowhere.

Point-of-Use Electric Tankless Water Heaters

first_imgA couple of years ago, I was standing at my kitchen sink, idly waiting the minute or so for hot water, noticing my poor parched backyard. Central Texas was (and still is) in the death grip of a prolonged, severe drought. Our lakes are in really bad shape, and we are under very tight water restrictions.Then suddenly, I had a mini epiphany: I’m wasting a lot of valuable water while I wait for hot water.I’m certainly not the first to have this realization, but it just killed me to be wasting all that water. I did a little mental math: 2.5 gallons probably 10 times a day = 25 gallons a day, which = 750 gallons a month. At $4/1000 gallons, that’s a minuscule financial hit — but hey, that’s just about a yard watering. It got me to thinking. First, the rumor about whole-house electric tankless being expensive was true. Besides the roughly $2,000 for the unit, we had to do a pretty massive upgrade to the electrical system. I don’t remember how much the work cost, but it was a lot.Second, the rumor about them not working very well was also true. But, we plowed on. I may have been driven, to some degree, by the fact I was going to inherit the water heater closet for my cramped shop. Not a small thing, indeed.We went through several models, and performance was always less than stellar. My family grew weary of my standard response to their complaints: “Hey, there are people in the world that don’t have any hot water.” This did not play well with teenagers (or wives). At the time of the incident above, we were actually using a propane-powered tankless system, fed from propane cylinders. True story. That heater provided much better performance, but it was definitely a bummer when the propane tank ran out during a shower! My family was always mad at me, but by now, it was way too late to give my tricked-out closet back to some water heater. A light bulb goes offWe happen to own a little cottage near the lake that we rent out. It had a small 40-gallon water heater that always smelled like rotten eggs. A while back, when the water heater croaked, I did some research, and replaced it with a small (10”x8”x3”) electric tankless unit from Niagara called a Titan N-120. It’s made in America, got pretty good reviews, and was a piece of cake to install. The renter loves the extra space in the tiny kitchen, loves the instant hot water, and is happy to have the rotten eggs smell gone. I am an inventor of sorts — at least that’s how I’ve made my living for the last 20 years. My most famous product was the original plastic folding sawhorse called StoreHorse. That was a long time ago, and they are now mostly cheap knockoffs. I don’t mean to cast myself as some prolific genius type, but my point is that, almost by definition, as an inventor, I’ve always had a certain lack of respect for conventional wisdom. You won’t get far in this business doing things the way they’ve always been done.So now, back to me standing at my kitchen window watching the grass die while perfectly good water goes down the drain. It seems like I decided then and there to go on a campaign to place a POUET — a point-of-use electric tankless water heater — at every location where we need hot water.The driver was not to save money on my water bill, nor was it to save money on my electric bill; it was to save water. Yes, I am well aware that my 750 gallons a month is the proverbial drop in the bucket (pun intended), but I just thought it would be a good thing, and that’s just the way I am. We’ve tried a lot of optionsI’ve been tankless for years. My house of 32 years does not have access to natural gas. Consequently, we originally had an electric tank-style water heater. Back then, I didn’t know much about anything, but I knew that this was the worst way to make hot water. So, I did a little research, and bought a whole-house electric tankless water heater. All in all, it was not a great experience. RELATED ARTICLES Domestic Hot Water: No Perfect SolutionAll About Water HeatersGBA Encyclopedia: Water HeatingGet Rid of Your Gas Water Heater!Are Tankless Water Heaters a Waste of Money?Storage vs. Tankless Water HeatersWaiting for Hot Water Small, medium, and largeLuckily, I am an extreme do-it-yourselfer. I did my own wiring and plumbing. It turns out that the work was really pretty easy.I bought an assortment of seven POUETs; some from Craigslist, some from Amazon, and some from eBay. The size of the units ran the gamut.At the small end of the gamut was a simple 110-volt, 2.4-kW, 20-amp Eemax unit that I installed in the downstairs half bath. With very little ability to raise the temperature, but with the included extreme flow restricting aerator, washing hands is all it needs to be: just OK.In the middle of the gamut was a new Niagra Titan N120 that I bought off of eBay for about $220. At 220 volts, and drawing 54 amps, it took running a new 6/2 cable in a conduit outside the house. I installed the unit over the showerhead in the tub in the kids’ bathroom, and I hooked it up to the sink as well. The kids say it’s the best hot water they can remember ever having in this house. I painted the unit, because frankly it was pretty ugly. Maybe it’s still a bit ugly, but I’ve always been a “form follows function” kind of a guy.At the furthest extreme in the gamut were two Titan units that I installed in series, again over the showerhead in the tub, in the master bathroom. The reason I installed two is that my wife likes to take scalding (and I really mean scalding) baths, while I take showers. Each of the Titans has four settings or buttons. When she takes a bath, she turns on all eight clicks. When I take a shower in the winter, I turn one unit completely off, and the other on about two or three clicks. In the summer, I only use one click, and I wish there was a way to use half of that. An end to wasted water and wasted energyNow, I am an evangelical POUET convert.Currently, my son and I are remodeling his new older house, and we are using POUET water heaters for the house. One of my buddies, who has been in the biz for years, says I’m @#$%&ing crazy. “Have you ever stood outside and watched the meter spin when that thing is on?” he says. Well, I say that’s conventional wisdom talking. I say that it takes the same amount of energy whether you do it fast or slow. Physics is physics.What’s more, a non-tankless (see, that’s convert talk) system suffers from all the familiar stuff like stand-by losses, cold pipes carrying hot water, hot water being left stranded, etc. But, it’s not just about savings; there is so much more to it, like:Having hot water before you can even fill a glass is a wonderful amenity. It’s like a garage door opener: once you have one, you can’t go back. How many times have you turned on the hot water to wash your hands, and then given up on the wait and just washed them with cold water? Talk about waste — all that hot water summoned, then abandoned. One of the harder habits to break is the routine we all do: turn on the shower, then go do something else while you wait for the hot water. With a POUET heater, the water is hot before I can get around the curtain.Having the ability to adjust the water temperature on the spot is another great feature. On my son’s house, I am working to make all the units as accessible as possible. While he’s a convert, he still is not quite on board with putting the units out in plain sight. But, with what I know now, it seems near criminal to use the energy to heat the water up, then dilute it with cold water. A perfect system allows you to have the hot water you want without using the cold water valve.If a heater goes out (which should seldom happen) you are not left dead in the water (another intended pun). And, replacement is relatively easy.There is, of course, the well-known advantage of endless hot water.If you are installing a POUET heater in a new build, or an extensive remodel, you only have to run a single water line.The units can go just about anywhere: no flues, no fumes, no vents. Some jurisdictions may try to apply “tanked” codes to tankless heaters, but that’s all part of the learning process.They are darn near 100% efficient. This does not address the debate about the inefficiencies of plant-generated electricity, but the fact is that virtually all of the power goes to raising the water temperature. For utilities, there are time-of-use issuesNow, there is one downside that I cannot address: “peak demand.” Power companies will probably not, um, … embrace this idea. They will see all those homes, all spiking the system with their morning showers, all at the same time. I don’t know, I’m not smart enough to know how bad that will be. But, I say, maybe it should be weighed against all those homes not wasting 10,000 gallons a year. Here and now, with the acute shortage of water, it might be a worthy tradeoff.On a recent AIA home tour, I queried several of the designers and builders of touted “green” homes about POUET water heaters. They all wanted to discuss their state-of-the-art recirculation systems. To me, POUET is easier, cheaper, and more efficient.After all these years of lamenting the lack of gas in my home to heat water, I would now choose POUET over some gas-fired system.Someday, I think that POUET will be “conventional wisdom.” In the meantime, my yard is still parched.

Study shows rhinoceros beetle horns evolved to accommodate speciesspecific fighting styles

first_img(Phys.org) —Male rhinoceros beetles have elaborate horns, which they use when fighting for mates. The shape and number of horns differ from species to species. Erin McCullough of the University of Montana at Missoula and her colleagues have discovered that horns evolved to have shapes that best suit each species’ fighting style. The research appears in the Proceedings of the National Academy of Sciences. Journal information: Proceedings of the National Academy of Sciences Play Rotating view of the 3D horn models used in the finite element analyses. Credit: Erin L. McCullough, PNAS, doi: 10.1073/pnas.1409585111 The team predicted the cross-sectional shapes of the horns of each species, considering which shapes would maximize the ability to dislodge opponents, using that species’ style of fighting. They thought cross sections of Trypoxylus horns would be triangular, those of Golofa would be circular and those of Dynastes would be elliptical. Microcomputed tomography scans proved their predictions correct. The team suggests researchers perform further studies on the effect of horn shape on other measures of fighting performance, such as grip and stability. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Considered the strongest animals in the world, male rhinoceros beetles compete for females by attempting to remove their opponents from trees and shoots and throw them onto the ground. They use their horns as weapons. Horns come in a wide variety of shapes.McCullough and her team wanted to find out why so many different horn types had evolved. They did not find any evidence that females chose mates based on horn size or shape, so they hypothesized that horn shapes evolved to improve fighting ability. Previous studies on the horns and antlers of ungulates supported this hypothesis. Among ungulates, males with long horns tend to fence or wrestle, males with curved horns tend to ram and males with short, smooth horns tend to stab.To see if rhinoceros beetles also had horns suited to their particular fighting styles, the team used a type of computer modeling system, known as finite element analysis, to calculate the stresses and strains the horns would experience when used for different methods of fighting. They studied three species: Trypoxylus dichotomus, Golofa porteri, and Dynastes hercules. All of these species have differently shaped horns, which they use in different ways. Trypoxylus has pitchforked-shaped horns that it uses to pry and twist opponents off tree trunks and branches. Golofa has long, slender horns that it uses like fencing swords, lifting opponents and throwing them off balance when fighting on narrow shoots. The head and thoracic horns of Dynastes form pincers, which the beetle uses to lift and squeeze opponents, then toss them to the ground. Models showed that a species’ horns experienced the least stress and strain under conditions that mimicked species-typical fights.

McCullough, PNAS, DOI: 10.1073/pnas.1409585111 AbstractThe shapes of sexually selected weapons differ widely among species, but the drivers of this diversity remain poorly understood. Existing explanations suggest weapon shapes reflect structural adaptations to different fighting styles, yet explicit tests of this hypothesis are lacking. We constructed finite element models of the horns of different rhinoceros beetle species to test whether functional specializations for increased performance under species-specific fighting styles could have contributed to the diversification of weapon form. We find that horns are both stronger and stiffer in response to species-typical fighting loads and that they perform more poorly under atypical fighting loads, which suggests weapons are structurally adapted to meet the functional demands of fighting. Our research establishes a critical link between weapon form and function, revealing one way male–male competition can drive the diversification of animal weapons.
