George Mason. Leicester City. Buster Douglas. These narratives are the reason we keep coming back year after year.Recently, though, it seems like the improbable has taken a back seat to the foreseeable — at least in a few major American sports.On Monday at 8 p.m. Eastern, the Alabama Crimson Tide and Clemson Tigers will clash in the College Football Playoff final. It will mark the fourth consecutive season the two will have met in either the finals or semifinals. On the hardwood, the Cleveland Cavaliers have battled the Golden State Warriors in the NBA Finals in four consecutive seasons.1That streak, however, will … not continue. And on the ice, the Washington Capitals have skated into the Pittsburgh Penguins in the second round of three consecutive Stanley Cup Playoffs.But though it might seem like it happens all the time, it’s actually pretty rare for the same teams to square off in the postseason year after year.For example, the MLB playoffs date back to the late 19th century and feature only three instances of teams meeting three seasons in a row.2The Anaheim Angels and Boston Red Sox played each season from 2007 to 2009, the Kansas City Royals and New York Yankees played each season from 1976 to 1978, and the New York Yankees and New York Giants played each season from 1921 to 1923. The NFL playoffs have seen a single instance of teams meeting exactly four years in a row3The San Francisco 49ers and Green Bay Packers played each season from 1995 to 1998. and a single instance of teams meeting five years in a row.4The Oakland Raiders and Pittsburgh Steelers played each season from 1972 to 1976. In the WNBA, the Minnesota Lynx and Phoenix Mercury played in four consecutive playoffs from 2013 to 2016. In the men’s NCAA basketball tournament, there have been eight instances of teams meeting in three consecutive tournaments.5Seattle and Oregon State played each season from 1962 to 1964, Utah State and Arizona State played each season from 1962 to 1964, UCLA and San Francisco played each season from 1963 to 1965, UCLA and New Mexico State played each season from 1968 to 1970, UCLA and Long Beach State played each season from 1970 to 1972, Providence and Pennsylvania played each season from 1972 to 1974, and Utah and Kentucky played each season from 1996 to 1998. And in the women’s NCAA basketball tourney, Notre Dame and UConn faced off in the Final Four, in either the semifinals or finals, an incredible five consecutive times from 2011 to 2015.

And in college football, where turnover among top-tier programs is unavoidable and injuries are prevalent, it’s striking that the same two contenders are about to produce a tetralogy. After bruising, monthslong schedules, we’re left with orange and crimson once again.Even though the teams are familiar, there’s still plenty to be excited about in Monday’s title game. Don’t let the betting line fool you; this year’s installment promises to be the best matchup yet between the two schools. In college football, the playoff is so new that it’s harder to look at consecutive matchups in a historical context. But we can guess at which teams might have faced off in a playoff by looking at the teams that ended each season since World War II in the top four of Elo ratings.

This year’s Alabama squad ranks first (96.9) of all Football Bowl Subdivision teams in that time frame, and Clemson ranks 15th (91.6). Each enters the game racking up more than 525 yards and 44 points per contest, so it will no doubt be the best offensive matchup we’ve seen in the playoff between the two programs. Compared with each previous meeting, this will be the worst Alabama defense Clemson has faced and the best Tigers’ defense the Tide has played — though the two teams are separated by only about 4 points of defensive efficiency.Alabama’s program has never been known as a high scorer, but it now features the most efficient offense of any team in the past 14 years. But the Tide will stare down a defensive line that is months away from playing in the NFL,6With the notable exception of Dexter Lawrence, who remains suspended over a banned substance found in a drug test. which is likely why the Tigers tout the nation’s third most-efficient defense since 2005.Quarterbacks under Alabama head coach Nick Saban are often more game manager than gunslinger and generally operate in a system that skews conservative. Not this year. No team averages more yards per passing attempt than Alabama’s 11.34.

The passing attack has accounted for 50 touchdown passes8To just six interceptions. and a team Total Quarterback Rating of 94.1, the best marks produced by an SEC offense over at least the past decade.The offense of Clemson head coach Dabo Swinney features an elite rushing attack, and quarterback Trevor Lawrence could become the first freshman QB to lead a team to a national championship since Oklahoma’s Jamelle Holieway in 1985. Where the team is most improved, however, is in its ability to dominate the line of scrimmage on the defensive end. “They wanted to be the best ever,” Swinney said of his defensive line, which leads the nation in sacks (52), quarterback contacts9Which measures the total number of times opposing quarterbacks were hit by a team’s defense.

Under defensive coordinator Brent Venables, the unit averages 7.96 expected points added per contest on run defense, the fifth-best mark since the statistic was first tracked in 2004.The trophy case at both schools is getting full: Alabama is looking for its third title in the past four years, while Clemson is looking for its second in the past three. But don’t think these two programs are approaching the game as just the humdrum, foregone conclusion of their seasons.

Deschamps admits they could do better

first_imgFrance international team’s coach Didier Deschamps admitted the squad could, in fact, do better after they won the controversial clash with Australia with a result of 2-1.The European team were the first team to make use of the video assistant referee technology and were awarded a penalty, which caused debates. Eventually, it was converted by Antoine Griezmann.“It was not easy, but winning the first match is very important,” Deschamps told SkySports.“It was complicated today with a team who gave us a hard time.”Euro 2020Report: Euro 2020 qualifying Group H George Patchias – September 11, 2019 Euro 2020 qualifying Group H is being controlled by France and Turkey, but Iceland is still in with a shout.Reigning world champions France ran…“It’s hard to explain everything. We missed a change of pace, a little juice.”“At the end of the match, we had a few more opportunities. It’s hard for everyone, apart from the first match of the Russians against Saudi Arabia (a 5-0 win),” Deschamps went on to add.“We did the job. But we can do better, do a lot better.”France will be facing Peru next Thursday in the next game of the group.last_img read more

That doesn’t mean they’re not passionately watching the 2018 World Cup and cheering on their native Sweden and England. As destiny would have it, those teams play each other today for a place in the semi-finals.No stranger to provocations and pokes, Ibrahimovic offered to buy Beckham dinner if England wins, but wants a paid trip to Ikea in case Sweden ends up on top. Beckham didn’t back down. Instead, he upped the ante by offering to buy anything Ibrahimovic wants if Sweden wins. However, if the opposite occurs, Ibra would have to come to an England game at Wembley wearing an England shirt and eating fish and chips.Opinion: De Bruyne is the best crosser since Beckham Tomás Pavel Ibarra Meda – September 13, 2019 We never thought we would see anything remotely like it, but now we can say that De Bruyne is the best crosser since Beckham.Nobody…LA Galaxy’s main attraction likes what Sweden has done so far (Independent.ie):“They have a big chance to win the World Cup. They beat Mexico (in the group stage) which was good. They made a big statement and by winning against the Swiss,” He also thinks controlling emotions is key in such a high-stakes game:“Now, it’s not only about how good you are, but there are a lot of emotions in the game. It’s a quarterfinal, and a lot of emotions come into the game. Whoever can handle that best has an advantage.and can’t wait to collect his prize:“When Sweden wins, let’s see what David Beckham tells me.”The two have known each other for quite some time. They faced off on the pitch many times over the years and also played together in PSG. This is nothing more than a friendly bet, and a fun one as well.last_img read more

Arsenal goalkeeper Petr Cech discusses Arsenal move

first_imgArsenal goalkeeper Petr Cech has discussed the new planing style under new manager Unai Emery.The former Chelsea shot-stopper was in fine form against Manchester City on Sunday making some important saves despite struggling to help the team play out from the back.“They’re a team that’s full of confidence and last year’s champions, so obviously it will always be difficult, but I have to say that we came to the game with our objectives to grow up as a team, to learn our way, how we want to play and obviously we had the task of doing it against one of the best teams, so it was difficult. But at times we did really well, and we put them under some pressure as well. Unfortunately, we just couldn’t find that final pass to finish the opportunities off,” Cech said as regards to City, according to the club’s official website.Jadon SanchoMerson believes Arsenal should sign Sancho Manuel R. Medina – September 14, 2019 Borussia Dortmund winger Jadon Sancho might be the perfect player to play for the Gunners, according to former England international Paul Merson.Cech also spoke about his struggles to play the ball from his pots, saying:“They pressed really well and obviously when you make one pass slower than it should be the player doesn’t have the time to use the ball quickly. Obviously you can be under pressure but at times we managed to get out pretty well. We didn’t want them to feel comfortable and have the ball always at their feet so that they could control the game.”Arsenal next travel to Stamford Bridge to face Chelsea next weekend.last_img read more

New State Marijuana Tax Rate Effective January 1

first_imgThe current tax is $50 per ounce for bud or flower, and $15 per ounce for other plant parts. These taxes are paid wholesale, when plants are sold from grower to retailer or manufacturer. Leif Abel, owner of Greatland Ganja in Kasilof: “So in essence we are paying the tax before the money has been made on the product, because the actual money comes from when the retailers sells that product to the end consumer. So, we’ve got a tax structure where the tax has to be paid on the product far before the end consumer ever pays for it, by the cultivation company who created it.”  At their meeting on Wednesday, they confirmed the new tax rate of immature, malformed or seedy marijuana bud at $25 per ounce. Facebook0TwitterEmailPrintFriendly分享The Alaska Department of Revenue and the Alaska Alcohol and Marijuana Control Office confirmed a new marijuana tax rate effective on January 1, 2019.

Are Houstons Sinking Suburbs Suffering Worse Flooding

first_img X To embed this piece of audio in your site, please use this code: 00:00 /03:37 Listencenter_img Source: Journal of the International Society for the Prevention of Mitigation of Natural HazardsTop map shows worse subsidence in blue since the 1990s. Bottom map shows it moving northeast in 2011.What made last month’s flooding, especially in north Harris County, so bad?Simple: a whole lot of rain says Mike Talbott, executive director of the Harris County Flood Control District.“It has a lot to do with this phenomenal rainfall … people don’t want to talk about the rainfall,” Talbott tells News 88.7.But people are talking about how other factors, besides the massive rainfall, may have made things worse. And one those people is a professor of geology at the University of Houston, Shuhab Khan.“It’s making it worse,” says Khan.What Professor Khan believes is making flooding worse in certain neighborhoods is a geological condition Houston and many cities suffer from and have for decades:  subsidence. It’s where many acres of ground sink.Historically in Harris County, subsidence has been worse in areas where over the decades, groundwater and oil and gas have been sucked out from under the ground, causing the land to sink by fractions of an inch a year, in some places by feet over many years.Could it be that today, the ground that homes are built on is sinking in different places than it did decades ago and thus, could this make flooding worse in places where people say, “It never flooded like this before.”When Professor Khan looked at maps showing where last month’s flooding damaged the most homes, those maps looked eerily similar to ones he’d drawn as part of a study two years ago, maps showing where subsidence was happening in Harris County.“Those are the areas that are areas that are subsiding very rapidly. North and northwest. It used to be Jersey Village. (Now) it’s moving northeastwards, north and northeast these days. But it is the same area where the flooding was,” Khan tells News 88.7.Khan says one subsidence zone is drifting northeast towards the Woodlands and seems to be affected by fault lines that traverse the area. Khan is not saying that subsidence alone is why there’s flooding.“Of course there would be flooding. But maybe not huge,” says Khan.At the Flood Control District, Mike Talbott does not agree.“It’s not subsidence,” Talbott told us. “It didn’t have any role in this event, it really was about the rainfall. This was phenomenal rainfall that caused some phenomenal flooding. “Source: Harris County Flood Control DistrictPink shows areas of major flooding April 18thTalbott doesn’t deny subsidence exists. He says the county has been studying it for decades.“Thirty years ago we got ahead of the curve and went ahead and did a major joint study with a bunch of agencies to understand the phenomenon,” says Talbott.Talbott says from those studies they learned that where subsidence is occurring in Houston’s northern suburbs, it’s not like a bowl where if your house is at the bottom you’ll be flooded worse.Instead, he says the sinkage occurs over such a wide area of many square miles that it does not significantly change the depth of the flooding, nor he says will it slow down the flow of creeks in those areas.“Cypress Creek, the subsidence actually is along the creek, the headwaters subsided nearly the same rate as mouth of the stream so the floodplains would move with the land. You wouldn’t have a change in the flow carrying capacity of the system,” Talbott tells News 88.7.Put another way, Talbott is saying that even though the northwest suburbs may have sunk a few feet, they’ll still drain just as fast. He says that’s because those suburbs are still about a hundred feet higher than where the water is headed, which is the Houston Ship Channel near downtown.“The stream just wouldn’t recognize that slight of a change in its slope to really affect the flooding in those areas. It’s a very weak relationship between subsidence and flooding for this region,” Talbott says.It is a complicated geological occurrence that has a long history of debate, a debate renewed when homes flood and people want to know why. 1995 Harris County Subsidence Study Sharelast_img read more

UPDATE Mueller Using DC Grand Jury In Russia Probe Source

first_img Share APSpecial Counsel Robert Mueller departs after a closed-door meeting with members of the Senate Judiciary Committee about Russian meddling in the election and possible connection to the Trump campaign, at the Capitol in Washington, Wednesday, June 21, 2017. (AP Photo/J. Scott Applewhite)Special counsel Robert Mueller is using a grand jury in Washington, D.C., in connection with his investigation into Russian efforts to influence the 2016 presidential election and possible collusion between Russia and top aides to the Trump campaign, a source with knowledge of the investigation confirms to NPR’s Peter Overby. The source did not want to be identified because of the sensitivity of the matter.The Wall Street Journal first reported that Mueller, a former FBI director, was using a grand jury. The latest development signals the former FBI director’s investigation is “growing in intensity,” with the grand jury beginning work in recent weeks, the Journal reported.A spokesman for Mueller declined to comment to NPR.Ty Cobb, a recently appointed White House special counsel focused the on Russia probes, said in a statement provided by White House press secretary Sarah Huckabee Sanders that he wasn’t aware Mueller had started using a grand jury.“Grand jury matters are typically secret,” Cobb said. “The White House favors anything that accelerates the conclusion of his work fairly….The White House is committed to fully cooperating with Mr. Mueller.”President Trump has maintained there was no collusion between Russia and his campaign during the 2016 election. And Trump has, at times, cast doubt on the determination of the U.S. intelligence community that Russia was behind various efforts to interfere in the election, including the hacking of emails belonging to Democratically-aligned individuals and organizations and the strategic release of those emails at key points in the campaign last year.But in a statement Wednesday announcing he had signed into law a bill imposing sanctions on Russia, Trump said he supported “making clear that America will not tolerate interference in our democratic process and that we will side with our allies and friends against Russian subversion and destabilization.”Trump has repeatedly called Mueller’s probe a “witch hunt” and some media reportshave indicated the president has looked into ways to undercut or even fire Mueller.“With respect to the impaneling of the grand jury, we have no reason to believe that the President is under investigation,” Jay Sekulow, a lawyer on the president’s outside legal team, told NPR’s Tamara Keith.The revelation that Mueller’s investigation is utilizing a grand jury comes as CNNreports investigators have zeroed in on “Trump and his associates’ financial ties to Russia as one of the most fertile avenues for moving their probe forward,” with sources telling them that the “web of financial ties could offer a more concrete path toward potential prosecution than the broader and murkier questions of collusion in the 2016 campaign.” That includes ongoing investigations into former White House national security adviser Michael Flynn and Trump’s former campaign chairman Paul Manafort.But Mueller dipping into Trump’s own personal finances is exactly what the president argued to the New York Times last month would be a “violation” of the scope of investigation delineated at the time Mueller was appointed by the Justice Department.Reuters is also reporting that grand jury subpoenas have been issued regarding Donald Trump Jr.’s June 2016 meeting with a Russian attorney who Trump Jr. was told would have incriminating information about Democratic presidential nominee Hillary Clinton.last_img read more

Physical chemistry could answer many questions on fracking

first_img(Phys.org) —By some estimates, continued growth in hydraulic fracturing (or “fracking”/”fraccing”) could put the US on the path to self-sufficiency in energy over the next few decades. Yet despite the potential economic benefits, fracking has also generated controversy due to the unknown long-term consequences of all the drilling, pumping, fracturing, and extracting processes involved. Now, two scientists have identified several important scientific challenges encountered in fracking that can be addressed with physical chemistry, which could lead to improved fracking techniques. Journal information: Journal of Physical Chemistry Letters Citation: Physical chemistry could answer many questions on fracking (2013, March 5) retrieved 18 August 2019 from https://phys.org/news/2013-03-physical-chemistry-fracking.html Other questions include how much natural gas is absorbed by the porous shale, how much natural gas (and other hydrocarbons) is present in source rocks, whether these can be produced, whether fracturing fluids can be designed to reduce the amount of salt and trace metals that are extracted along with the hydrocarbons, how proppants (additives used to “prop” open the fractures) change the flow properties of the hydrocarbons, how back-flow water is treated after it flows back to the surface, how to minimize natural gas and oil leaks at the surface to avoid contaminating aquifers, and many more. “We believe that proper fundamental investigations and attention in the application of the hydraulic fracturing technology will be able to limit the environmental impact of hydraulic fracturing,” Striolo said. “Although accidents can always happen, proper planning and attention to safety and environmental regulations will limit the likelihood of such events.”Essentially every stage of the fracking process poses fundamental questions, but Yethiraj and Striolo think that physical chemists, with collaboration from researchers in other fields, are capable of providing answers. Both scientists are currently investigating questions that could impact fracking in the future. Yethiraj and his group are developing models for water and aqueous solutions and investigating the static and dynamic properties of water-soluble polymers. Striolo has been investigating the thermodynamic and transport properties of aqueous systems confined in narrow pores. He is also participating in an international initiative (Deep Carbon Observatory https://dco.gl.ciw.edu), whose goal is to better understand the Earth’s carbon cycle. The results from these areas of research could help answer some of the questions highlighted in the commentary. Copyright 2013 Phys.org All rights reserved.

English tremors blamed on shale ‘fracking’ The process of hydraulic fracturing involves drilling a vertical and horizontal well, which can allow the exploration of wide shale formations (up to 6,000 acres) with only a small surface pad (6 acres). Points A, B, C identify the locations for future research opportunities. Credit: Arun Yethiraj and Alberto Striolo, et al. ©2013 American Chemical Society Physical chemists Arun Yethiraj, a professor at the University of Wisconsin-Madison, and Alberto Striolo, an associate professor at the University of Oklahoma in Norman, have published an overview of how physical chemistry could lead to a better understanding of fracking in a guest commentary in The Journal of Physical Chemistry Letters. Over the past several years, fracking has become more widespread in the US as a relatively cheap way to produce natural gas and oil. The basic process involves drilling into the ground, first vertically and then horizontally; lining this well with a metal casing that contains small holes; and then pumping water (with some additives) into the well at high pressure, which flows through the holes and causes the surrounding rock to crack open. Out of the open cracks in the rock, fluids such as natural gas, oil, and about 10% of the pumped water can flow back to the well and be collected at the surface.While fracking is currently being used with commercial success, much is still unknown about the details of the process. In 2012, the US National Science Foundation funded a workshop on hydraulic shale fracturing that brought together scientists and engineers from a variety of backgrounds. In the new commentary, Yethiraj and Striolo draw upon the information from this workshop to address the fundamental scientific problems that arise in fracking, and briefly propose how they might be solved with tools from physical chemistry.”We attempted to outline many physical chemistry questions, to engage the broad community,” Striolo told Phys.org. “Every scientist can target a question of his/her personal interest. The impact on the development of the fracking technology, however, is likely to depend on a global systemic approach, where all aspects we pointed out, and others, are tackled together.”For instance, some of the big questions in fracking require a better understanding of the physical properties of fluids in shale, which could be addressed by methods that characterize the shale microstructure and nanostructure, as well as measurements that monitor changes in rock properties upon infiltration of fluids. And since only 10% of the water that was pumped into the well flows back out, where does the rest of it go? If the water is absorbed into the shale, how does it affect the rocks’ response to mechanical movement? Experimental data, computer simulations, coarse-grained models, and theoretical studies could help answer these questions.
