Larz Anderson Bonsai Collection marks centennial

first_imgThe Larz Anderson Bonsai Collection at the Arnold Arboretum celebrates its hundredth anniversary in America this year. The plants were originally imported in 1913 by the Honorable Larz Anderson, upon his return from serving as ambassador to Japan. The core of the collection consists of seven large specimens of compact hinoki cypresses Chamaecyparis obtusa ‘Chabo-hiba’—now between 151 and 276 years old—that Anderson purchased from the Yokohama Nursery Company. These plants provide a direct link to the early 1900s, when Americans and Europeans, infatuated with the Far East, were passionately collecting cultural artifacts from Japan.While the sixteen plants that currently make up the Larz Anderson Collection are not the oldest dwarfed plants in the United States, they have been under cultivation longer than any other examples currently growing in North America—with the lone exception of three plants at the Brooklyn Botanic Garden that were imported in 1911. The Arboretum plans a number of special events this fall to celebrate the beauty and historical importance of this singular collection of dwarfed plants; details will be announced this spring. Currently off display for the winter, the collection will return to public view in April. Read Full Storylast_img read more

Williams making noise for UW’s return team

first_imgMATTHEW KUTZ/Herald photoAfter watching the first two games of Wisconsin’s 2005 season, it’s hard to believe senior Brandon Williams hasn’t been returning punts his whole career.”Brandon gives us someone who has speed, who likes to be there, who likes the challenge,” Wisconsin head coach Barry Alvarez said. “Brandon wants the ball in his hands and has been a playmaker for us ever since we’ve had him. Hopefully he can continue.”Williams has made the most of his opportunities this year, translating five punt returns into 124 yards in the two contests and a 66-yard score in last Saturday’s win over Temple. The St. Louis, Mo., native’s performance against the Owls was also good enough to earn him Big Ten co-special teams player of the week honors. All this from a guy who had yet to field a punt in his previous three years of college entering this season.”You’ve just got to kind of find [the football], you’ve got to have that vision to just get there,” Williams said. “I think that’s just a natural thing that I have. I really haven’t tried to work on changing anything. It’s just finding a crease and hitting it and just being explosive. It’s just something that you do.”Williams’ success on special teams hasn’t been limited to punt returns. The senior wide receiver has also seen his average on kick returns jump from 19.0 yards a season ago to 61.5 yards this year. Though he has only returned two kicks due to a pop-up kickoff strategy utilized by Bowling Green in University of Wisconsin’s season opener and Temple’s inability to score a point in Saturday’s lopsided affair, Williams has shown an explosiveness that wasn’t present in the kick return game in 2004.”I think it’s a combination of things,” Williams said of the improvement thus far. “[Special teams coach Brian Murphy] has been hitting us real hard with the scheme and everything and everybody’s really buying into it. It’s just opening up; it’s opening up real good. I just think that’s really the key for kick returning, being able to hit it quick, find a seam, no hesitation.”As a team, Wisconsin has been extremely efficient and effective with its special teams. Sophomore kicker Taylor Mehlhaff connected on his only field goal attempt of the season and has made 16 of his 17 extra point attempts. Mehlhaff’s greatest value, though, may be on kickoffs, where he has posted touchbacks (10) on half of his chances (20).”The kicking game sets up or determines field position,” Alvarez said. “Last week as an example, our average field position was the 50-yard line. [Temple’s] was the 19. Now, how many times we had possession as compared to theirs, now that’s a huge advantage.”Behind Mehlhaff’s strong left leg the Badgers are currently limiting opponents to an average of 18.3 yards per kick return. For the season, Wisconsin’s average starting field position is its own 45.5-yard line. By contrast, their opponents have averaged starting on their own 21. That field position advantage has, in part, helped Wisconsin’s offense to average 60.5 points per game, which is tops in the nation.”Some of our real good teams, if you go back and study the 1999 (Rose Bowl) team, we had a 15-yard difference in where we took the ball over as compared to our opponent, times how many possessions you have during the game is the hidden yardage that no one takes account of,” Alvarez said. “That particular year we didn’t throw the ball well, or we didn’t throw it a lot, but we made that difference up in the kicking game.”Alvarez is banking on the improved special teams’ play to carry over to Saturday’s contest at North Carolina, a team that scorched Wisconsin for 246 yards and a touchdown on six kick returns in the two teams’ last meeting during the 2003 season.”Well, obviously, if you drill it deep they won’t return it,” Alvarez said. “So that is a considerable help. They executed it well, since that day we made some adjustments in our kickoff team and how we kick and some of the things we do.”last_img read more

Gatlin stuns Bolt to win 100m world title

first_imgLondon, United Kingdom | AFP |  American veteran Justin Gatlin was booed after he stunned Usain Bolt to win the 100m world title in London on Saturday.Gatlin, who served a doping ban between 2006-10 and won silvers behind Bolt at the last two world championships, clocked 9.92 seconds, with teammate Christian Coleman winning silver in 9.94sec.Bolt suffered a dreadful start and could only claim bronze in 9.95sec.“I’m sorry I couldn’t end it on a winning note, but I want to thank you for your support,” said Bolt, who embraced Gatlin after they streaked through the line with no clear victor immediately apparent.“It’s been a wonderful experience as always.”Gatlin was afforded the same rough reception as he had in the heats and semi-finals, loud boos and jeering ringing around the same stadium where in 2012 his rivalry with Bolt was presented as ‘good against evil’, given the American’s doping-tainted past.But Gatlin has form as the last man to beat Bolt over 100m — by a hundredth of a second in Rome in 2013 — and at the age of 35, can still produce the goods, something he has in the past ironically credited with his four years of forced exile from the track.Ayana routs rivals to take world title Olympic champion Almaz Ayana produced an extraordinary display despite barely racing this season winning the world 10,000 metres title by almost a minute on Saturday.The 25-year-old, who smashed the world record when winning in Rio last year, finished in 30:16.32 , over 46 seconds clear of her legendary compatriot Tirunesh Dibaba, the three-time Olympic gold medallist and five-time world champion who took silver after being unable to go with the scorching pace of the winner.Kenya’s Agnes Tirop took the bronze. Uganda’s Mercyline Chelangat finished 14th in a personal best time of 31:40.48 .South African Manyonga wins world long jumpSouth African Luvo Manyonga won gold in the men’s long jump at the IAAF World Championships in London on Saturday.The 25-year-old, Olympic silver medallist in Rio last year by just 1cm, leaped a best of 8.48 metres.American Jarrion Lawson took silver with 8.44m, with another South African, Ruswahl Samaai claiming bronze (8.27).Share on: WhatsApplast_img read more

Source: Ex-Trump Lawyer Michael Cohen to Be Released from Prison

first_imgPresident Trump’s longtime lawyer and fixer, Michael Cohen, is about to be a free man.Cohen is set to be released from federal prison on Thursday, due to the risk of coronavirus on inmates. He is expected to serve the rest of his sentence at home, according to a source.He has been held at FCI Otisville in New York, after pleading guilty to charges of campaign finance fraud and lying to Congress.The 53-year-old began serving his sentence a year ago and was scheduled to be released from prison in November 2021.Attorney General William Barr ordered the Bureau of Prisons earlier this year to increase home confinement and release eligible high-risk inmates.The Bureau of Prisons has placed Cohen on furlough as it continues to process his move to home confinement, the source familiar with the matter said. The agency has the authority to release inmates on furlough for up to 30 days.A federal judge had previously denied Cohen’s attempt for an early release to home confinement, saying in a ruling earlier this month that it “appears to be just another effort to inject himself into the news cycle.”However, the Bureau of Prisons can take action to move him into home confinement without a judicial order.Other high-profile inmates have also been released from the federal prison system amid the pandemic.Former Trump campaign chairman Paul Manafort was released on home confinement last week.Meanwhile, Michael Avenatti, the attorney who represented adult star Stormy Daniels in lawsuits against President Trump, was temporarily freed from a federal jail in New York City.last_img read more

New Amazing Animal Discoveries

first_imgFrom spiders to mammals, the living world never ceases to amaze us with new wonders.  Some are inspiring new technologies.Frog’s tongue ‘can lift three times own body weight’ (Jonathan Webb in the BBC News).   It’s not just muscle, but shape and coating that allows frogs to be tongue weightlifting champs.  The researcher confessed to having fun to finding out new things about frogs.Spiders build sonically-tuned webs (Thomas Sumner in Science Magazine).  They’re not just food-catchers; they’re musical instruments.  Spiders have been found harping on their webs, tuning them up, and listening in to the music of the death dance of captured insects.  “The team proposes that spiders tune the tension in their webs like a guitar string by plucking the silk strands and listening to the resulting echoes, creating clearer vibrational signals from captured prey.”  The findings could “inspire new lightweight sensors.”Fish-eating spiders ‘widespread’ (BBC News).  They’re on almost every continent, and scientists didn’t even know.  “Scientists have discovered that a number of spider species catch and eat fish,” even fish much larger than themselves.  To go fishing, they anchor their hind legs on the land and scout the surface of the water.  Upon catching one with their fangs, they haul it in, carry it off, and reduce the fish to liquid with their toxins.  Afterwards, they slurp in the fish cocktail.How cormorants emerge dry after deep dives (MIT press release).  “A combination of modeling and laboratory tests has now determined how both chemistry — the preening oil that birds use — and the microstructure of feathers, with their barbs and barbules, allow birds to stay dry even after emerging from amazingly deep dives.”  The find was inspiring: “This might lead to the design of artificial surfaces that do the same thing.”  It was reported a decade ago, too (5/24/04), that cormorants’ eyes rapidly refocus during the dive to allow accurate vision in both air and water.The noisy world of mud crabs (Northeastern University).  Researchers at Northeastern found out that crabs can hear the sounds their predators make, and alter their behavior accordingly.  This was not known about marine crabs before.  “They didn’t hear the same way we do—through the impo­si­tion of sound waves on our audi­tory machinery—but rather through bil­lions of dis­placed par­ti­cles knocking against the tiny hairs inside their statocysts.”African swallowtail butterfly: Scientists unravel the genetic secrets of nature’s master of mimicry (University of Exeter).  Researchers have discovered a “genetic switch that allows female swallowtails to look like different Monarch butterflies and thus avoid being eaten.”  The biologists were surprised.  “By pinpointing the switch, we have revealed a unique mechanism,” the press release says.  “It is really exciting to show that all this diversity is determined by variation in just a single gene.”When the bat sings (Virginia Morell in Science Magazine).  A whole new dimension has been revealed about bats: they can sing!  Like birds, they can serenade females and issue warning calls.  The article includes a number of sound files so readers can hear the warbles, chirps and birdlike chatter that would be hard to distinguish from birdsong  were it not mostly ultrasonic.  A researcher noted that “each male’s song is unique—rather like a jazz player riffing on a tune.”Finally, a whole new “tropical Eden” in southeast Suriname is just now being explored by scientists.  It’s one of the last untouched tropical reserves in South America.  Readers can ride along in a boat watching the embedded video clip on PhysOrg, wondering at all the new plants and animals awaiting classification.  It took a lot of planning and work to get there:The team surveyed four sites in the upper Palumeu River watershed, going from low floodplains to isolated mountain peaks. They received invaluable support from 30 indigenous men from nearby communities, who went ahead in boats through dangerous rapids to help bring 2,000 kilos of food and equipment, set up camp sites, cook meals and guide the team through the forests. From Paramaribo, the scientists chartered a plane to a village in Southeast Suriname and from there reached their first camp site by helicopter.The scientists collected data on water quality and an astonishing total of 1,378 species, including plants, ants, beetles, katydids, fishes, amphibians, birds and mammals.Water quality was good, and there was very little evidence of human contamination, except what must have blown in from regions outside the reserve.At CEH, we rejoice over scientific discoveries, and encourage exploration of creation’s wonders.  It’s the Darwinian storytelling we can do without.  Thankfully, there was very little in these articles.

Ductwork for ERVs, Dehumidifiers, and Forced-Air Heating Systems

first_imgDavid Treleven is an industry manager at Therma-Stor where he concentrates on innovation and technical applications. Is it possible for an ERV, a whole-house dehumidifier, and a forced-air heating and cooling system to share ductwork? The answer is yes — but these systems need to be designed with care.This article describes what I believe to be the best ways that these three appliances can share ductwork. Since there are many different products in these three appliance categories, and since each product has specific operational requirements, HVAC contractors should always follow manufacturer’s installation instructions. (In this article, references to a “dehumidifier” always refer to a whole-house dehumidifier.) The gold standard: each appliance has separate ductsWe cannot discuss integrated HVAC systems without first speaking about unintegrated systems.  By “unintegrated,” I mean that the ERV, dehumidifier, and air handler all operate independently of each other, and that each system has dedicated ductwork that isn’t shared with another appliance (see illustration below).Using separate dedicated ductwork means that simultaneous operation of the blowers from two different appliances won’t cause pressure problems, and ensures that there won’t be any need for larger-than-normal ductwork. This approach may be the gold standard in terms of system performance, but often is also the most expensive.The air handler and the dehumidifier can share ductsIt’s possible to design a system in which the air handler and the dehumidifier share ductwork (see the illustration above). This is the most common way to integrate a dehumidifier with a forced-air heating system, with or without an ERV.  With this approach, the dehumidifier and the air handler share the same supply ductwork, while the ERV uses a completely separate duct system.With this approach, the supply ductwork must be sized to account for the extra flow of the dehumidifier.  Note that if the air handler’s supply ductwork is not properly sized, it’s possible that when both the air handler and the dehumidifier operate together, one or the other may exceed the maximum operational static pressure, decreasing performance.  The lower the operational static pressure when both are running, the better the performance from both pieces of equipment.I don’t recommend supplying the air from the dehumidifier to the return side of the air handler, because during times of simultaneous operation the cumulative latent capacity is severely affected and the performance is unpredictable. (For more on this topic, see the FSEC report titled “Investigation of Energy Impacts of Ducted Dehumidifier Duct Configurations and Location.”)The ERV and the dehumidifier can share ductsIn some situations — for example, in a house with ductless minisplits, or in a house with forced-air heating and cooling with a high static duct system, or in a house with a radiant cooling system — you might want your ERV and your dehumidifier to share supply ductwork (see illustration above). These ducts are not shared by the forced-air heating and cooling system.  The supply air from the dehumidifier and ERV should go to the bedrooms, while the dedicated return for the dehumidifier should pull from a large central portion of the home. The ERV should pull stale exhaust air from potentially contaminated areas.  This setup requires a backdraft damper on the dehumidifier supply duct prior to connection with the ERV, in order to prevent supply air from the ERV from being supplied out the return of the dehumidifier.The static pressure of the shared supply duct will change based on whether the dehumidifier is on or off.  Depending on the ERV, this change in static pressure may change the flow rate of the outside air provided to the house by the ERV.During commissioning, there are two ways to balance the ERV:Balance the ERV with the dehumidifier on. If you do this, the ERV will go slightly unbalanced and will positively pressurize the house when the dehumidifier is not on. (This is my preferred method).Balance the ERV with the dehumidifier off. If you do this, the ERV will go slightly unbalanced and will depressurize the house when the dehumidifier is running.Correctly sizing the shared supply ductwork and terminations will greatly reduce the amount that the ERV goes unbalanced, one way or another.A tandem arrangement: ERV plus dehumidifierThere are positives and negatives to all of the above approaches.  As stated above, when a dehumidifier and ERV share ductwork, there is the potential that the ERV will become unbalanced at certain times.  If this concerns you, and you are willing to turn the dehumidifier blower on whenever the ERV is on, the setup shown above may be better for you.  In this case, we are avoiding the unbalanced situation; the trade-off is that the ventilation system will have a higher operating expense.  The approach shown above requires the supply duct leaving the ERV to be connected to the outside air collar on the dehumidifier.  It is important that the dehumidifier still maintain a return from the house, since the flow from the dehumidifier will not match the flow of the ERV supply. (There are other reasons as well – but that is a topic for another article).A motorized damper is required in the duct from the ERV to the dehumidifier to prevent the dehumidifier from drawing in outside air when the ERV is off.  This is important during outdoor pollution events (for example, during wildfires or skunk sprays) or unoccupied times (for example, during vacations or work hours).  When the ERV is being commissioned, the dehumidifier should be on in order to properly balance the ventilation system.The fully integrated “injection” approachThe last option that we will discuss is a fully integrated application (see illustration above).  Both the dehumidifier and ERV are installed as injection devices in which the return and supply of these appliances are connected to the same piece of ductwork.  This “injection” design creates a near zero operational static pressure for the injection devices and has no impact in terms of increased air flow (and thus static pressure) on the air handler.  So there is no need to upsize the ductwork.  This provides predictable performance of all the different components of the system.  However, bath fans would be required with such an installation as the ERV can no longer provide removal of pollutants.For this approach to be effective, the air handler blower must be on whenever the ERV or the dehumidifier is operating. The ERV should be installed on the return side of the air handler so that the ERV doesn’t add or remove BTUs from the supply side of the forced-air heating and cooling system.  The dehumidifier ducts should be located on the supply side of the air handler so as to not reduce overall latent capacity of the system.This approach increases latent performance (moisture removal) when the air conditioner and dehumidifier run simultaneously, as the air entering the dehumidifier is closer to the dew point. (Check with the dehumidifier manufacturer to ensure this is an acceptable application as it often is not within manufacturer’s specifications.)  Yes, the sensible BTUs of the air conditioner are impacted (mechanically changing sensible BTU removal to latent BTU removal), but during peak conditions the air conditioner should be able to maintain acceptable indoor humidity levels.  Therefore, during non-peak hours we have extra capacity that can be exchanged for better latent control.  It should be noted that the dehumidifier will have little to no latent capacity if it operates simultaneously when the heat source for the home is on and being distributed through the supply side of the air handler.I hope this article sparked some talking points. Integration of different systems by different manufacturers can become tricky, as each manufacturer has only their own system in mind. We all have the same goal, however: a healthy indoor environment supported by the predictable and efficient performance of the home’s HVAC equipment.center_img RELATED ARTICLESAll About DehumidifiersAll About Furnaces and Duct SystemsDucting HRVs and ERVslast_img read more
