Photo Gallery Under Stepsis’ guidance, the Bulldogs’ defensive unit finished last season ranked in the top-10 nationally in five major statistical categories, including scoring defense (19.1 points per game) and total defense (296.0 yards per game). “It’s been nothing but energy and excitement around here, and the players really have been at the forefront of that,” Stepsis said. “They’re the ones that have really bought into what our vision for the program is. It’s a group that has high aspirations and plays at a high level.” Drake begins its season on the road at North Dakota on Aug. 31 at 4 p.m. before kicking off its home opener against Truman State at 6 p.m. on Sept. 7 inside Drake Stadium. Drake returns 39 letterwinners and 13 starters from a year ago, including AP All-American defensive back Will Warner. Warner finished second in the nation with a school-record eight interceptions. The Bulldogs boast seven other returning players who garnered all-conference recognition in 2018. Those returners include stalwart defensive lineman Erin Morgan, who enters the season as one of the nation’s top pass rushers. Head coach Todd Stepsis enters his first season at the helm after being appointed on Dec. 21, 2018. Stepsis served as the defensive coordinator for five years prior to being named head coach. Story Links The Bulldogs are looking to build off a strong 2018 campaign in which they finished 7-4 overall and tied for second in the Pioneer Football League standings. DES MOINES, Iowa – The Drake University football team hosted its annual media day on Thursday, Aug. 8, speaking with local media to preview the upcoming 2019 season.

Two teams of evolutionists are having a spat over whale evolution. Thewissen and team (Northeastern Ohio U) say the hippo is close to the pig, but Jessica Theodor (U of Calgary) and Jonathan Geisler (Georgia Southern U) say it’s in the whale family tree. Their arguments and counter-arguments were published in Nature last week.1 Science Daily gave Theodor and Geisler time to tell their side of the story. Theodor and Geisler feel that DNA phylogeny needs to be taken into account, which their opponents failed to do. They worked several phylogenetic trees with living and fossil animals that put hippopotamids in the line with raoellids, Indohyus (an extinct Indian pig-like animal), and cetaceans (whales). One of their trees treated all characters equally, another suppressed homoplasy (convergent characters). They also omitted Andrewsarchus, a dog-like predator known only from one skull and a few bones. In addition, they took into account the thickening of bones in the ears of both whales and hippos, which they took as evidence of common ancestry. Thewissen et al agree with parts of their opponents’ tree but think hippos are closer to true pigs. They say the thickening of bones in the hippos and whales are due to different molecular mechanisms. Hippos, they say, appeared after the cetaceans, and in Africa, not Pakistan, where most of the whale ancestor candidates have been found. Science Daily said, “Geisler and Theodor argue that leaving out the DNA data not only ignores important information, it implies that the evolution of swimming evolved independently in hippos and whales, when it may have evolved only once in a common ancestor.” Thewissen et al said, “Geisler and Theodor place confidence in their results with regard to hippopotamids by stating that their analysis is consistent with ‘previous phylogenetic studies’. However, one of the two articles that they cite was published after the publication of our paper, and they do not cite a recent paper that disagrees with their (and our own) results.” Apparently there are other positions besides these two. “We also believe that improving fossil collections of poorly known taxa is important in advancing understanding of cetacean relationships.” One position that was not considered by either team is creation. For that perspective, see Jonathan Sarfati’s article on whale evolution from Creation Ministries International.1. Brief communication arising, J. H. Geisler and J. M. Theodor, Nature, E5 (19 March 2009) | doi:10.1038/nature07775; Reply by Thewissen et al, Nature E5 (19 March 2009) | doi:10.1038/nature07775.Remember that whale evolution was #1 in Nature’s “15 Evolution Gems” published in January (01/02/2009). They advertised this list again this month (03/18/2009). But read their spiel and you’ll find it’s full of speculation and appeals to the future: “there is every reason to think that many others await discovery,” they said – so keep the credulity dollars flowing into the Darwin Party coffers. Whale evolution was also the darling of the episode on “Great Transformations” in the PBS Documythary series, Evolution (see 12/20/2007). This little controversy appearing in Nature shows that the case is not so tight. The arguments on both sides reveal the usual tricks of the Darwin Party: appeals to theory-laden concepts like convergent evolution, tweaking of tree-building software, and the weighting of uncooperative lines of evidence to get the results they want. It’s time to step back and look at the big picture: can you really link a whale, a pig, a hippopotamus and a dog into a family tree? The morphological differences between these groups are arguably greater than their similarities, despite the fact they are vertebrates and air-breathing mammals. Each animal group is perfectly happy living in its specialized environment without trying to become something else. Each animal is well adapted to its habitat, possessing all the machinery and systems needed to thrive (see news about hippo sunscreen). Only by picking and choosing which pieces of evidence shall be garnered to support a preselected story would a silly human mind imagine joining them together into a genealogy. There’s another controversy brewing. Two groups of evolutionary carpenters are fighting over the evolution of the concrete saw, which requires water for its operation. Both agree it is related to the bench saw, but one party says both are related to the power drill, and another says they are related to the reciprocating saw. One view makes the circular motion of the drill and the concrete saw a case of convergent evolution; the other makes the motors products of a common ancestor. The evolutionary carpenter guild may have internal disputes about the details, but one thing is clear: these tools did evolve from each other, because they are all members of the electrical power tool clade. All evolutionary carpenters agree: evolution is a fact!(Visited 329 times, 1 visits today)FacebookTwitterPinterestSave分享0

Man was I in for a surprise when I opened the container! While avoiding the ants and other crawley things, this one took me a few minutes to get worked around. Just glad to have figured it out. #7 with HerroSone. Submitted this one to Geocaching.com as one of the best field puzzles around!!” – Wild Dog Clan“Got this with the kids after a long day at the beach! Awesome Cache!” – Superhero Team“Its Caches like this that keep this game interesting. Not what we were expecting… Everyone took turns at retrieving the nano. WOW! Mahalo For The Cache!” – KALA696What the geocache owner, ValerieAndMason, has to say:“A few years back there was a flurry of urban nano hides (with spotty coordinates) that kind of took the fun out of the game for a large portion of the active geocachers on Oahu. My wife and I actually like nanos so I began thinking of unconventional ways to hide them, this is the one that started it all. It’s a pvc pipe maze that was built to fit the container, I had no idea what it was going to look like when I started. There was no blueprint just “what ever looked good”. I’ve already told myself that if this one goes missing, the replacement will be twice as big and ten times harder so for everyone’s sanity I hope it never gets muggled.The goal is to make something different that will excite or even frustrate (sorry) others but still gives them a sense of satisfaction once it’s done. Favorite points are always appreciated but never expected, when we do get them we know we did something right.We really enjoy reading the logs and find ourselves going back to read them all again, from the FTF to the most recent. They also help to keep us motivated to find and build even more creative caches.We can only hope that our geocaches keep the game fun and exciting for others and gets the gears turning for those brilliant minds out there. We know that ammo cans in the woods are the most popular and preferred geocache, especially for the veterans, but the handmade, imaginative ones are the most memorable to us.” Photos:You’ll have to work the geocache through the tubes from start to finish.The nano and the tubes in their case.The geocache in the wild.

RELATED ARTICLES As Steven Knapp and his wife plan a new house in Atlanta, indoor air quality (not energy efficiency) is at the top of their priority list. At least that’s how a recent discussion on autoclaved aerated concrete began.“We both have chemical sensitivities that make ‘usual’ building practices undesirable,” Knapp writes in a Q&A post at GreenBuildingAdvisor. “Before the market bottomed, we were planning to build a healthy house following Baubiologie practices (as much as practical) and using autoclaved aerated concrete for the structure.”Knapp and his wife put their project on hold as they waited for market conditions to improve, and in the interim, Knapp says, local AAC installers largely disappeared. “As a consequence, we set about designing a house that would use conventional framing and as many no- or low-VOC materials as possible,” he says.Increased residential construction is pushing up the cost of conventional building materials, and AAC contractors are back in the picture. That’s making Knapp wonder whether the 15% premium he thought he’d have to pay for AAC construction may actually be worthwhile.“My question is,” he writes, “are you professional builders seeing big price spikes? Are they broad and large enough that I should take another look at AAC?”While construction costs ostensibly are at the heart of Knapp’s question, the issue also touches on the merits of autoclaved aerated concrete, and that’s the subject of this Q&A Spotlight. Green Basics: Concrete BlockUnderstanding R-Value Q&A: Bau Biologie — The First Green Building Movement Autoclaved Aerated Concrete BlocksStructural Systems & Components STRATEGIES & DETAILS Consider lightweight autoclaved aerated concrete GREEN PRODUCT GUIDE AAC block: higher cost, lower R-valueTo GBA senior editor Martin Holladay, an AAC wall will never be able to compete with conventional wood framing on a cost basis.“Moreover,” Holladay writes, “AAC walls have a very low R-value — most are in the range of R-8 to R-11 — and often require poured concrete bond beams that result in horrendous thermal bridging.”R-values that low are not what Knapp has been planning on. “The ‘effective’ R-value of an 8-inch block is around 21,” he replies. “I know that’s not stellar, but you can create a very airtight structure with AAC.”Also, Knapp adds, there is an alternative to a poured concrete bond beam that would have a lower energy penalty.“Perhaps my best course is to invite the AAC builder to bid on the project and see how it compares,” Knapp says. Comparing AAC to concrete block constructionAn alternative that would outperform AAC in the Atlanta area would be a wall made from old-fashioned concrete masonry units (CMUs) wrapped in 1 1/2 in. of polyisocyanurate foam insulation, Dorsett says. That wall would keep all of the thermal mass of the block inside the thermal envelope, and it would meet local codes. “But for the cost of AAC there’s usually more performance to be had elsewhere,” Dorsett says.If structural integrity and hurricane resistance is a top priority, Knapp might also consider building with insulating concrete forms (ICFs). The reinforced concrete at the core of the ICF wall will be much stronger than either an AAC or CMU wall. The air quality questionThe conversation is enough to get Knapp to take AAC “off the table” and move forward with a stick-built design that will meet the EarthCraft House Platinum standard.“We are very focused on limiting or eliminating VOCs in the structure,” Knapp writes. “We are also insisting on an accurately sized HVAC (no best guesses) and an energy-recovery unit for air exchanges. The house will be all-electric and have no combustion sources (not even a fireplace).” Better performance with an alternativeHolladay thinks “effective R-value is an example of deceptive marketing hype.” GBA reader Dana Dorsett doesn’t go quite that far, but he suggests caution when comparing “effective R-values” of this building material to the more reliable R-values of other wall assemblies.For starters, the “dynamic benefit for massive systems” — one approach to calculating “effective R-value” — most often cited by the people who sell AAC is based on a particular house design tested by the Oak Ridge National Laboratory, Dorsett writes, and unless Knapp is planning building exactly the same house there’s no guarantee he will get the same performance. In fact, the performance of AAC will “vary substantially” with the climate, weather and season, the actual house design and site conditions, he says.There’s more. “AAC has a very high vapor permeance and moisture absorption — a moisture reservoir that passes both water vapor and liquid water more readily than most building materials, making it a far-less-than-perfect choice for Atlanta’s high latent-load summertime issues,” Dorsett says. “You’d probably be able to build a true/stable R-20 (or even R-30) wall by other methods (and more appropriate moisture control) for the money, and have lower overall cooling/heating loads.”Low-perm paints and sealers don’t do much to control the problem, Dorsett says, and they simply peel and flake away. Only semi-permeable paints can be used. “In the cooler, drier air of northern Europe it does OK from a moisture performance point of view but it’s so low-R that it doesn’t meet current thermal requirements without adding exterior insulation.”AAC might be worth considering in some drier climate zones in the U.S. with high daily temperature swings, Dorsett adds. “But not in the muggy-sticky Southeast.” Our expert’s opinionWe asked GBA technical director Peter Yost for his take on this question. Here’s his reply:While I was at the NAHB Research Center (1993–2000), we worked on AAC as part of the DOE Advanced Housing Technology Program, and built one of four townhomes out of AAC, on a Superior Walls basement foundation. The trades grew to like the block because it could be cut and routed and was relatively lightweight. The local fire department (and the Center’s insurance company, no doubt) grew to like it when vandals started a fire in the unfinished AAC unit, with no damage. That said, this was not the first time AAC attempted to find market share in the U.S., and it was not the last, although each time it simply has not taken hold.For a pretty comprehensive discussion of the pros and cons of AAC, check out the GreenSpec Insights recent blog — including the extensive posted comments discussion — as well as this UC Davis Extension paper.And it is certainly worth reviewing this ORNL paper, which assesses the energy performance of AAC, by climate.My cut?Individuals with chemical sensitivities should assess materials on a case-by-case basis, focusing their efforts and finances on materials that they know are problematic (and crude as it may be, one of the best indicators is to sleep with your materials, placing small samples of materials on your nightstand and seeing how you feel the next morning).From a hygrothermal standpoint, the pore structure of AAC can vary considerably from formulation to formulation, significantly affecting its moisture and energy performance (at least one AAC manufacturer has a data file in the latest WUFI Pro materials database, but it is unclear how that applies to other AAC materials).AAC attempts to be a stand-alone building envelope system for the U.S. market, but it simply has never convinced any industry leaders or bulk market interests to sustain a manufacturing presence in the U.S. There are considerably more reasons not to use this system than there are to use the system.
Pippa Middleton, sister-in-law of Prince William, is reportedly back with her old flame Earl Percy after splitting from banker boyfriend and former cricketer Alex Loudon.Pippa, 28, and George, 27, were seen spending weekend together at a Remembrance Day service in Alnwick, Northumberland. “Their arrival caused a stir and they were very much together. The fact they came to such a public event says a great deal, as does the fact Pippa was with his family,” mirror.co.uk quoted a source as saying.George is heir to the Euro 300mn Duchy of Northumberland. This is not the first time they are sported together. George spent a week in Madrid with friends where Pippa was also seen spending time.”Pippa and George have always had a special relationship. Alex used to get jealous because they danced together and got close at social events,” the source added.
Arsenal manager Unai Emery has told his players to expect a similar physical battle to Burnley when they face Brighton on Wednesday.The Gunners defeated Burnley 3-1 on Saturday with Pierre-Emerick Aubameyang, who scored a brace, claiming he had never played in a game that was so physical.There were a number of incidents involving physical challenges and Clarets manager Sean Dyche afterwards accused Arsenal players of diving.The win was enough to take Arsenal level on points with fourth-placed Chelsea and Emery expects Brighton to offer a similar challenge to his players.“Brighton is the same, a very tough match physically, very organised and, like with Burnley, a very good coach who is working very well.” Emery said, according to BTSport.Merson 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.“It is a challenge and I respect those teams a lot because they also have good players. They decide to do a line-up with physical players with a lot of crosses for the strikers for heading in our box.”“We need to defend very far in our box to defend better against that.”The challenge for Unai Emery’s men, who lost to Brighton last season, is made more difficult due to a defensive injury crisis, with Rob Holding, Konstantinos Mavropanos, Hector Bellerin and Nacho Monreal all out with injuries.
