Children’s flu cases turn deadly after bacterial infection

first_imgJul 11, 2007 (CIDRAP News) – Health officials in Perth, Australia, last week advised parents to seek medical care quickly for young children with respiratory symptoms, after three children under age 5 died of pneumonia as a complication of “mild” influenza A infections.Paul Van Buynder, director of communicable disease control for Western Australia’s health department, said in a Jul 6 press release that officials were surprised by how quickly the illness developed in the children. “While we do not want to create unnecessary panic, it is important for parents to be aware that the disease can cause serious illness within 24 hours,” he said.The children who died had a streptococcal pneumonia infection, but health officials have not announced what type, according to a recent report from Australian Broadcasting Corporation News.The cases started out as “mild influenza A infection,” Van Buynder told the Australian Associated Press. He said the health department found no links between the children’s cases. Australia is at the peak of its flu season, and the report said hospitals in the Perth area were inundated by anxious parents bringing children with flu symptoms.News of the Australian cases comes as infectious disease and public health experts are worrying about the threat of a flu pandemic associated with H5N1 avian flu. In past flu pandemics, bacterial coinfections have contributed substantially to deaths.The Australian report also is a reminder of recent worries US health officials have had about rising numbers of young flu patients who have suffered coinfections with the sometimes-fatal Staphylococcus aureus pneumonia, in some cases involving drug-resistant strains.S aureus can cause a severe, necrotizing pneumonia that has a relatively high case-fatality rate—33% during the 1968-69 flu pandemic, the CDC said in an Apr 13 Morbidity and Mortality Weekly Report article that detailed some of the recent fatal cases.Evidence points to a synergistic relationship between S aureus and influenza, according to an article in the June 2006 issue of Emerging Infectious Diseases. Flu viruses appear to increase S aureus adhesion in the respiratory tract, and S aureus-specific enzymes (proteases) appear to increase flu virus replication. Also, influenza A virus strains appear to decrease destruction of S aureus by immune cells called phagocytes, making patients more susceptible to bacterial coinfection.In May the US Centers for Disease Control and Prevention (CDC) issued an alert after noticing an increase in the number of S aureus infections in children with flu. The CDC said that from October 2006 through early May, 55 influenza deaths in children had been reported. Twenty of the children (out of 51 for whom relevant data were available) had bacterial infections, and 16 of these were infected with S aureus.Though the number of pediatric flu deaths this past flu season was similar to the two previous years, the CDC said the 16 deaths from S aureus pneumonia or bacteremia recorded so far reflected a sharp increase over those years. Only one S aureus coinfection was identified during the 2004-05 season, followed by three in 2005-06.Further, of the 16 children who had S aureus infections, 11 had methicillin-resistant (MRSA) strains that are typically associated with MRSA skin infection outbreaks, the CDC advisory said.The CDC also noted that the children who had S aureus infections had been in good health before they got sick, but progressed rapidly to serious illness.Anthony Fiore, MD, a medical epidemiologist with the CDC, told CIDRAP News that because childhood flu deaths have been nationally notifiable only since 2004, it’s difficult to make definitive statements about pneumonia death patterns. “It is concerning, and there is a surge in awareness, particularly with the antibiotic resistant strains of Staphylococcus,” he said.The CDC has other ways to track pneumonia trends in children with influenza, he said. For example, the Emerging Infections Program and the New Vaccine Surveillance Network are two systems that can capture clusters of severe infections in children that lead to hospitalization.Edward Septimus, MD, an infectious disease expert who is medical director of clinical integration at Methodist Hospital in Houston, told CIDRAP News that the clinical picture of the Australian cases possibly suggests a Group A Streptococcus organism. “It’s a severe clinical picture and it can act a lot like MRSA. The necrotizing effects are very similar,” he said. Jim Henson, the creator of the Muppets, died of a Group A streptococcal pneumonia, Septimus added.He said that without more information, it’s difficult to predict whether the Australian cases point to any troubling trends. Sometimes, he commented, patients are simply unlucky: Their risk of developing a serious pneumonia rises if they are colonized with a bacterial organism such as MRSA or Streptococcus when influenza viruses are circulating.See also:Western Australia Department of Health news releasehttp://www.health.wa.gov.au/press/view_press.cfm?id=711May 9 CDC health advisoryCDC.

Steelers pleased with themselves after NFL draft

first_imgEditor’s Note: To keep up with the latest news, opinion, lifestyles, sports and entertainment go to the Apple Store or Google Play and download the New Pittsburgh Courier App for iPhone, iPad or android devices. It’s free! Check it out and let us know what you think! MIKE TOMLIN (AP Photo/Keith Srakocic) by Will GravesPITTSBURGH (AP) — The Pittsburgh Steelers understand it’s going to take more than nine college players to address the surging number of needs on a roster in the midst of an unusual amount of transition.Still, over the course of three days, the Steelers believe they’re off to a solid start.Pittsburgh bolstered depth concerns on both sides of the ball in the final four rounds of the NFL Draft on Saturday to give an aging roster an influx of much-needed young talent.“We’ve done it the way we’ve always done it,” coach Mike Tomlin said. “It just so happened that particularly early in draft, the guys in the highest position on our board were in positions where we needed to add.”The Steelers spread their picks all over the field, taking two linebackers — including first-round pick Jarvis Jones — two defensive backs, two wide receivers, a running back, a quarterback and a defensive tackle. Pittsburgh even traded with rival Cleveland to add an extra selection in the fourth round to grab Syracuse safety Shamarko Thomas.By allowing the Steelers to move up and take Thomas, the Browns will receive Pittsburgh’s third-round pick in 2014. It’s a move general manager Kevin Colbert felt was necessary to land the 5-foot-9 Thomas, who defensive backs coach Carnell Lake compared to 2007 Defensive Player of the Year Bob Sanders.“I’m not worried about his size at all,” Lake said. “The kid has a 40-inch vertical and that kind of explosiveness gives him great range when it comes to making plays.”Thomas gives the Steelers a potential impact player to back up veterans Troy Polamalu and Ryan Clark. The 32-year-old Polamalu and 33-year-old Clark are entering the final stages of their career and key reserves Will Allen and Ryan Mundy signed elsewhere during the offseason.The aggressive jump to get Thomas gave the Steelers the chance to start planning — perhaps — for life after Ben Roethlisberger.Pittsburgh drafted Oklahoma star Landry Jones in the fourth round, the highest the club has taken a quarterback since using the 11th overall pick on Roethlisberger nine years ago.“I just think it was time to start grooming a new player, freshen up the room if you will,” quarterbacks coach Randy Fichtner said.Jones smashed every significant passing record during his four years at Oklahoma, throwing for 16,646 yards and 123 touchdowns while starting 50 of 52 games.Colbert allowed there’s a chance Jones “will never play” for Pittsburgh but didn’t want to let an opportunity to bring one of the most accomplished passers in NCAA history into the fold slip away.“When you have a franchise QB like we do, you don’t get a lot of opportunities to add a young quarterback into the mix,” Colbert said. “It’s a critical position. You better keep adding young folks to that spot.”The 24-year-old Jones said he had no contact with the Steelers until his phone rang Saturday afternoon. He considers himself a future NFL starter but has no issues coming in and learning the league behind a two-time Super Bowl winner.“On every single team there’s going to be a quarterback that has your job,” Jones said. “You’re going to go in there, you’re going to be respectful and do all these things and compete as hard as you can.”The Steelers have relied heavily on longtime backups Byron Leftwich and Charlie Batch when Roethlisberger has been unavailable. Both are now unlikely to return after Pittsburgh signed Bruce Gradkowski to serve as Roethlisberger’s top sub and drafted Jones with an eye toward one day having a younger guy in place should Roethlisberger get hurt.Fichtner said it is time for the 31-year-old Roethlisberger to become one of the guys who talks instead of the one who listens.“There has been a great respect between Byron, Charlie and Ben,” Fichtner said. “I think this gives Ben an opportunity to share his experiences. That is an exciting time.”Jones is already familiar with the Roethlisberger family. His wife, Whitney Hand, played basketball at Oklahoma with Roethlisberger’s sister, Carlee.“My wife is pretty pumped about this whole deal,” Jones said with a laugh.Even if it means Jones will have to wait his turn.“I get to learn from one of the best quarterbacks to play the game,” Jones said.Jones will have at least one familiar face in town after Pittsburgh drafted Oklahoma wide receiver Justin Brown in the sixth round. Brown spent the first three seasons of his collegiate career at Penn State before transferring to the Sooners in the wake of the Jerry Sandusky scandal.The 6-foot-3 Brown gives the Steelers a big target in the red zone. Brown joins third-round pick Markus Wheaton as new blood on a wide receiving corps that is wide open behind starters Antonio Brown and Emmanuel Sanders.The Steelers grabbed Illinois cornerback Terry Hawthorne in the fifth round. Hawthorne, considered more of a cover corner than a physical presence, gives Pittsburgh a dash of speed as a nickelback.Pittsburgh wrapped up the draft by taking Florida State linebacker Vince Williams in the sixth round and Samford defensive tackle Nick Williams in the seventh.Both players are considered projects, then again the Steelers figure most rookies need time to adjust to the NFL regardless of where they are selected.Thomas sounded like the rest of his brethren while talking about a future that will begin next week when the Steelers host a rookie minicamp.“I will play anywhere they want me,” he said. “I just want to be on the field. I want to help out the Steelers.”last_img read more

France’s national team depth will blow your mind!

Powered by Firework The squad depth of French National side will certainly blow your mind. The depth of their squad was one of the reasons behind their World Cup win. Now, it is seeming that France will be the favourites to win the European Championship in 2020 with this squad depth.Advertisement We are starting to analyse the squad of France from Goalkeeping position. Hugo Lloris is an obvious first choice Goalkeeper for France. In his absence Areola, Maignan and Lafont are capable of playing in that position. Lucas Hernandez, Digne, Ferland Mendy, Benjamin Mendy and Kurzawa are there to play in the left back position. Benjamin Pavard, Dubois, Sidibe and Dagba are there to play as right back.Advertisement In the left side of central defense, Laporte, Umtiti, Lenglet and Kimpembe can play for France. In the right side, there are Varane, Zouma, Konate and Diop. Kante, Pogba, Aouar, Rabiot, Tolisso, Guendouzi, Matuidi, Ndombele  and Sissoko are there to play in the defensive midfield position. Griezmann, Fekir or Payet can play the role behind the centre forward. Coman, Lemar, Dembele, Martial and Mbappe can show their class from the wings. On the other hand, Olivier Giroud, Ben Yedder or Lacazette can play as centre forward. The squad depth of France will certainly put pressure on other teams in Euro 2020.Griezmann admits to uncertainty looming over his futureAdvertisement Advertisementlast_img read more

Buttressing a faulty narrative

first_imgDear Editor,Public commentary in Guyana does come with personal attacks, especially when you upturn the traditional narrative on its head with new facts.I refer to an attempt to buttress the narrative offered by Dr David Hinds by two individuals. I thank them for their letter in the Stabroek News of Match 7, 2019. But rather than deal with the core issue at hand, they offer an academic illusion of ethnic harmony and political order, without understanding that such a situation can only be achieved when there are heavy doses of truth and integrity in public policy development and implementation.The traditional narrative that drives the ethnic disharmony and political disorder in Guyana is grounded in a fallacy that Indo-Guyanese are wealthy and thus a need for equity in how the Treasury is distributed. My previous letter has now put that to rest, and the only presumed oversight on my part was the source of my conclusion.Any letter writer to any media house will tell you that space is always an issue, and thus I deliberately left it out.My source was a World Bank document called “Guyana – Strategies for Reducing Poverty”. A proper interrogation of that document would lead anyone with the required training to conclude that some 22,000 Indo-Guyanese families do live in poverty, compared to 15,000 Afro-Guyanese families and 9,000 Amerindian families. All it takes is a bit of reading and mathematics to figure that out.Secondly, anyone with an iota of social inquisitiveness can conclude that, after some 7000 sugar workers were severed by Team Granger between 2016 and 2017, there would have been major poverty consequences. You have to be clearly foreign to the happenings in the sugar industry not to comprehend the gravity of the social-economic dilution that took place since 2016.Based on a statistical analysis of the population of severed workers done over October 2018, I have enough evidence to make that declaration public that some 3,000 Indo-Guyanese families were pushed into the army of the poor. This process was accelerated by the severance pay being withheld in some cases by almost a year by this heartless Granger Team. Were it not for the barrels and remittances coming from their loved ones in the diaspora, the impact on those families would have been worse.Unfortunately, the connected class aligned to Team Granger would want us to log on to the narrative that it is okay for Team Granger to spend G$1.3 billion to build the Durban Park Parade Ground, but delay the payment of the Wales Sugar Estate workers for almost a year. They totally ignore the fact that such an action drove hundreds of men who used to live in dignity into a life of indignity.As an example from my research, there were cases wherein many former sugar workers found themselves becoming petty thieves, who stole their neighbours’ “soap” from the outdoor showers.These truths do not find their place in the traditional academic narrative, because the purveyors of the traditional message do not want to feed this truth, but an alternative truth. Their alternative truth is one that provides excuses as to why it is okay for Team Granger and the PNC to progress their ethnic supremacist policies and attitudes, since it was supposed to bring ethnic economic equity to the society. Well, it clearly has not!Driving a programme that cultivates 200 Afro-Guyanese millionaires to match the 200 Indo-Guyanese millionaires is not equality, when very little is done to address the inequality for the over 50,000 families from all races living in abject poverty at the bottom of the economic ladder. So while the Granger Team may have brought economic equity at the top, by making many of the PNC boys and girls into millionaires and in a couple of cases billionaires, Guyana has regressed at the bottom, where too many of our people are living below the poverty line.But the fact remains that the largest ethnic group in this army of the poor remains the rural Indo-Guyanese, away from the lights of Georgetown. While the ethnic group with the highest percentage of the poor remains the Amerindians, in this case, percentages are useless, since a poor man is a real human being and must be counted as an individual, not a statistic.There we go, my source. Let us now progress the conversation on how we will fix the system to empower, enrich and enhance the lives of all of our people, especially those 50,000 families living at the bottom of the economic ladder.Sincerely,Sasenarine Singhlast_img read more

Language Strangles Scientific Ideals

first_imgBig Science doesn’t have a public relations problem. It has a propaganda problem.To hear science journal editors and science news reporters, you would think the gods are angry at stupid people. For example, on Live Science, Stephanie Pappas purports to explain “Why Americans Deny Science,” taking hold of the Yoda microphone to berate the unwashed masses. It’s not that the issues of “evolution, climate and vaccines” do not deserve informed discussion, or whether a fraction of the populace believes dumb things. It’s that her elitist stance begins and ends with the attitude, “We’re right, they’re wrong, that’s the end of the story” (see 12/23/16).The U.S. has a science problem. Around half of the country’s citizens reject the facts of evolution; fewer than a third agree there is a scientific consensus on human-caused climate change, and the number who accept the importance of vaccines is ticking downward.But there are reasons to doubt the “scientific consensus.”  Who says so? Members of the scientific consensus itself, that’s who. Consider these recent reports from the journals and mainstream media.Equivocation in scientific lingo. Scientific papers are known for their incomprehensible jargon. An ostensible purpose of the recondite rhetoric is to aim for precision in meaning. Here’s an example, though, of rhetorical imprecision. The phrase ‘risk factor’ sounds scientific, doesn’t it? What, exactly, does it mean? Medical Xpress points to the phrase as an example of imprecise language with multiple meanings (see Equivocation in the Baloney Detector). A post-doc scholar at METRICS (Meta-Research Innovation Center at Stanford) conducted a study of terminology in the literature, and found that ‘risk factor’ alone has four possible meanings. Annoyed, Anders Huitfeldt, PhD, had this to say: ”“I have had a long-standing interest in trying to understand why published research papers often fail to find the truth,” he said. “It seems that often researchers are confused about what they are actually trying to do.”The problem goes far beyond this one particular phrase. If scientists cannot even agree on what they mean by their own widely-used terminology, the very question they address in research gets muddled. “And this uncertainty becomes a serious impediment to processing information correctly to arrive at the scientific truth.” Conclusion: imprecision in phraseology is a risk factor for muddle-headed obtuseness.Buzz bombs. To show we are not alone in use of the term ‘Big Science’, observe that Nature uses it, too. “Big science has a buzzword problem,” a news feature in the respected journal announces. Megan Scudellari intones, “Moonshots, road maps, frameworks and more are proliferating, but few can agree on what these names even mean.” If scientists don’t know what they mean by a research project that’s going to cost the taxpayers tons of money (e.g., Biden’s “Cancer Moonshot”), how is the public supposed to know? Here’s that imprecision risk factor again:‘Moonshot’, ‘road map’, ‘initiative’ and other science-planning buzzwords have meaning, yet even some of the people who choose these terms have trouble defining them precisely. The terms might seem interchangeable, but close examination reveals a subtle hierarchy in their intentions and goals. Moonshots, for example, focus on achievable, but lofty, engineering problems. Road maps and decadal surveys (see ‘Alternate aliases’) lay out milestones and timelines or set priorities for a field. That said, many planning projects masquerade as one title while acting as another.It gets worse. Scudellari points out that projects labeled with these buzzwords “add unnecessary layers of bureaucracy and overhead costs to doing science, reduce creativity and funding stability and often lack the basic science necessary to succeed.” No wonder The Martian faced death-defying challenges. Scudellari provides disturbing examples of muddle in the Big Science – Big Government nexus. She notes in passing that “Science partly progresses by serendipity” in addition to moonshots, whatever those are. Serendipity can emerge as a flash of insight for one individual scientist.Have a nice epoch. Nature printed an interesting dialogue about the new buzzword “Anthropocene,” a proposed geological epoch that begins with human impact on the planet. (We note in passing that the words era, epoch, eon, and period, while essentially synonymous in English, take on artificial meanings in geology’s arbitrary classification scheme. The rocks know nothing of the ‘Geologic Column’ and couldn’t care less.) In his critique, Noel Castree argues that “it is folly to believe that there is an objective way to define a new ‘age of humans’.” His neologism ‘scientize’ carries a stinging bite:What counts as epochal change is a matter of perspective and emerges from judgements about when quantitative change morphs into qualitative transformation. The interpretive and critical parts of social science can help us to appreciate that formalizing the Anthropocene is a misguided attempt to ‘scientize’ a particular set of value judgements. No such formalization is needed to underpin arguments for humans to live in ways that are less environmentally destructive.Indignant members of the Anthropocene Working Group do their best to defend the term’s meaningfulness in their reply, but point out that once the term is settled, it will work with “physical scientists, social scientists, humanists and artists.” Something like the word evolution does?Hidden agendas. Speaking of buzzwords, Nature‘s editors introduced one with profound consequences for citizens. “‘Nature-based solutions’ is the latest green jargon that means more than you might think,” the headline says. “It may sound vague, but the term represents real and vital concepts.” Our first impression was that it refers to biomimetics. Not. In fact, freedom-loving conservatives need to watch out for this friendly euphemism, not just because the leftist journal Nature likes it, but because it could hit their wallets. Nature likes it because it sounds nicer to innocent taxpayers than the clunky phrases, ‘ecosystem services’, ‘green–blue infrastructure’ and ‘natural capital’.” By contrast, nature-based solutions has a nice ring to it (like ‘sustainable’ or ‘evidence-based’), enough to rally the globalists and policymakers:NBS — as almost no one yet calls it — is a newly coined umbrella term intended to sweep up all of the above phrases, add others such as ‘ecological engineering’ and ‘ecosystem-based mitigation’, and dump them into a policy-relevant pot, where sustainable practices that harness the natural world (wetlands to clean waste water, for example) can be devised, analysed and then pulled out for use by politicians, scholars and researchers….‘Nature-based solutions’ might sound like it belongs on the side of a gardener’s van, but the concept it represents is of vital and urgent significance. As the grand challenges that face society continue to build, so does the need for multidisciplinary, evidence-based strategies to, for example, protect water supplies, address habitat loss and mitigate and adapt to climate change. And if a concept is solid, then the alien words and terms that represent it have a habit of becoming familiar and bedding into everyday discourse.Hold onto your wallet, in other words. Nature grins at how other buzzwords, like biodiversity and sustainable development “emerged into policy debate” relatively quickly. Who are the debaters, you might ask? Big Science, Big Government, the UN, Big Media and all the other Big institutions that decide for the public what they want to do, then ask the public for their money.Foxes elect themselves guardians of the henhouse. Speaking of policy, Nature also reported that a meeting of the American Association for the Advancement of Science (AAAS) produced a document called the Brussels Declaration (odd, since they worked in Boston), “a 20-point blueprint for a set of ethics and principles to inform work at the boundaries of science, society and policy.” It’s nice that they care about ethics and integrity, but they get to define those words, too. Beware if they think integrity evolved by natural selection.One might think that scientists are already paragons of integrity. Why, then, was this declaration needed?Most policy decisions are informed by evidence that is provided by experts. All too often, who those experts are, how they are chosen and the true reliability of their advice is open to question. Key requirements for public dialogue and better understanding are transparency, scrutiny and inclusivity.Inclusivity—the buzzword that usually refers to certain sexual orientations—suggests that Nature and the AAAS will be happiest if two transgender lesbians who are transparent about their gay marriage are included in Big Science & Big Government confabs to inform policy for the rest of us.Automated bias. In the internet age, much of our information comes to us from Google searches. Many users might presume that answers to questions are evidence-based, transparent, and scrutinized with the appropriate inclusivity. Thomas Maher (U of Arizona) is concerned, though, that these answers may actually be promoting more falsehood online. He states on The Conversation that the top answer in a Google search on the question, “Did the Holocaust happen?”, led users to a neo-Nazi, white supremacist, Holocaust-denying website. In the article, Maher points out additional problems with Google answers. But the concern can cut multiple ways. What happens, for instance, if government censors decide what is fake news or fake science? As we showed in the opening Live Science article, one can imagine the kinds of answers Stephanie Pappas would give—were she put on a censor board—to questions about creation, evolution, or intelligent design.Power corrupts in many ways, not just financial. All humans, even scientists, are prone to promote their agendas and ideologies. Some take the shortcut of propaganda. The more power, the more ability to foist fake science through large, wealthy institutions.Avoiding propaganda requires moral qualities that Big Science admits is in short supply (else why need a Brussels Declaration?). Beware any expert who thinks that integrity evolves. That ideology could lead to things like Newspeak: war is peace, freedom is slavery, ignorance is strength.(Visited 29 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Foundation Plan for a Snowy Climate

first_imgIs there really a rot problem here?Malcolm Taylor replies that the stipulated 16-inch separation between ground and untreated lumber that’s mentioned in building codes refers to the structural components, such as deck beams outside the structure, not to exterior wall framing.“What governs there,” he says, “is a separation of 8 inches from grade to the top of the concrete foundation wall. Seeing as this is the case, and almost all houses in cold climates are built with wood framing which is covered by snow during the winter, is there really enough evidence of widespread rot to make you need to deviate from the how everyone else builds?”Stephen Sheehy takes a similar line. In Maine, where Sheehy lives, last winter saw more than 6 feet of snow piled against the north wall of the house for three months. “So long as the melted snow or rain drains away from the house, the sills are going to be OK,” he says. It’s drainage, not simply the exterior walls’ distance above grade, that really matters here.”Although Kevin Zorski also believes that the 8-inch-above-grade guideline is plenty adequate even for a snowy climate, he suggests that Scaglione could incorporate some pressure-treated material into the house near the ground to ease his worries about rot. If he does go ahead with the plan he’s already outlined, Scaglione might consider using an insulated concrete form (ICF) foundation, which combines rigid foam insulation and a structural concrete core.“These should probably go below grade as we’ll, as there is nothing in your drawing preventing frost from getting under your slab,” Zorski says. “Or you could extend foam down the inside of the stem walls to protect the soil under the slab.” Our expert’s opinionHere’s what Peter Yost, GBA’s technical director, adds to the mix:Any foundation and above-grade wall combination system, and with any cladding in any climate, works for me, so long as both bulk and capillary water are well managed.If you don’t manage both well, there is no combination of assemblies and claddings that will be robust and durable.In cold climates, you do see a lot of failures in walls where there is no capillary break in the transition from the below-grade portion of the wall to the above-grade portion, and in walls where the barrier to bulk water entry is not continuous. But these failures are more about the detailing than they are about the type of assemblies and claddings.Just to be sure, I checked in with GBA architect Steve Baczek, who does a lot of high-performance designs for cold climates. Here is what Steve had to say:“This is a water management problem. More specifically, a bulk water management problem. Snow against a wall doesn’t really bother me; what bothers me is what happens when the snow or ice melts. Where does the water go?“First, there is the question of the proximity of wood to the water. Code requires a distance of 8 inches between grade and a wood sill. Start with that. In addition, you should provide a relatively steeply sloped grade away from the foundation to make sure water doesn’t pool around the house. As snow melts, it will typically stay below the 8-inch mark. Nathan could increase that distance to 10, 12 or even 18 inches, but I don’t think that’s necessary.“The problem with Nathan’s wall as drawn is that’s it’s a single-wythe barrier. Because of that, I question how one manages any water or moisture in that system. On a rainy afternoon in late fall, for example, that block wall could get saturated with water, and then become susceptible to freezing through the night. Eventually, repeated freeze-thaw cycling will take its toll.“I think it’s important to build in a protective layer. If Nathan sticks with a lower wall made of block, he might build it with two layers of masonry and leave a gap between the two. This is similar to the suggestion from James Morgan. Alternately, Nathan could lower the wood-framed wall so it starts just one course of block above grade, but add a ventilated rain screen to create a capillary break. That’s better, but it still leaves a course of block at the base of the wall not as well protected as I’d like. Let’s not forget block is not as robust as a poured concrete foundation would be.“There’s one more potential detail he could consider — one I have used on a house in snow country: a layer of corrugated steel protects the bottom of the wall, with a layer of rigid foam insulation between the steel and the wood framing behind it. (See Images #2 through #4, below.)“In summary, keeping wood framing above the soil will certainly help, but true success lies in proper management of the water that the wall is bound to see.” Nathan Scaglione’s central New York State building site gets plenty of snow and cold weather during the winter, and that’s proving to be a sticking point in his plans for a new house.He’d prefer a slab-on-grade foundation rather than a basement, even though a full basement would be a more typical choice in this part of the country. The foundation would consist of concrete-block stem walls extending to a footing below frost line. Exterior walls would be framed on top of the block walls, roughly 24 inches above grade. Inside the block walls, Scaglione will pour a concrete slab floor. As he explains in a Q&A post at Green Building Advisor, Scaglione has seen this detail in garage construction, not necessarily for a house.“I would like to build on a slab with radiant floor heat,” he writes. “But I really can’t get behind the idea of melting snow sitting up against the stick frame and gradually rotting the walls. For everything except a [frost-protected shallow foundation], code says 16 inches above grade. Ideally I’d like to have the stem walls be 2 feet above grade. With a platform framed house, now we’re talking about the floor being close to 3 feet off the ground. From a design standpoint, I really don’t like being way up off the ground. I’d rather one step down and I’m walking on the grass.”The drawing Scaglione has provided (above right) includes the basics. The slab would be about 6 inches above grade, and doors would be “about one step off the ground.”Are there structural problems here that Scaglione is missing? Does this type of foundation have a track record? Those are the questions for the his Q&A Spotlight. Another option: Masonry veneer and a waterproof membraneTo James Morgan, it’s getting a little complicated. A simpler approach, he says, would be to frame the exterior walls from the slab. To guard against water damage, Morgan would apply a peel-and-stick waterproof membrane to the first 2 feet or so of sheathing, and protect all of it with a masonry veneer wall. (See the drawing at left for a sample of this construction detail).“Backfill against the masonry to your heart’s content,” Morgan says. “Protect exterior door sills with at least 4 feet of gable porch overhang. Exterior walls are insulated right down to the slab and you will have no jamb issues with inward opening doors.”Morgan says that finish grade can even be higher than the finish floor when necessary. “We’ve used variations of this kind of detail reliably for many years when at-grade entries are either preferred or required, e.g., for wheelchair accessibility,” Morgan adds. He concedes that his experience has been entirely in Climate Zone 4A, bordering a county with an even milder Climate Zone 3A, but there’s no doubt it’s been successful.Sullivan would be “paranoid” about the peel-and-stick membrane becoming a “wrong-side vapor barrier” and potentially allowing wood wall components to get wet by condensation.Another possible problem, Holladay adds, is that the brick veneer will draw soil moisture upward via capillary action. “This shouldn’t be a problem if the mason remembers to install through-wall flashing a few inches above grade, along with an adequate number of weep holes to allow drainage and to provide ventilation inlets,” Holladay adds. “Your sketch fails to show the flashing and weep holes, but these details are essential. They are also tricky, because the mason may not know how the excavation contractor plans to backfill and grade the site.”Says Morgan, “I did not go into into the complementary details which I assumed would be taken for granted in this forum: proper roof water management strategies, good overhangs, proper surface grading, etc. But bottom line: I see a clear advantage in a clean and consistent wall insulation and service run condition all the way to the interior floor level. (Maybe I missed it but nobody seems to have mentioned the problems that the electrician and the plumber would face in the originally proposed configuration).“Stepping out to grade seems to be Nathan’s core performance requirement,” Morgan continues. “I stand by a construction strategy which with appropriate local detailing offers a way to achieve both objectives without making a dog’s breakfast of the exterior wall construction.” CONSTRUCTION DETAILS Foundation/Floor Connections A full basement would be a better choiceGBA senior editor Martin Holladay sees no structural problems with Scaglione’s plan, and he agrees with Scaglione’s concerns about water damage to the lower parts of exterior walls when they’re only 8 inches or so above grade. Increasing the separation between soil and wood can’t hurt.Still, Holladay would proceed differently: “I would go for a full basement (with poured concrete walls, not CMUs), and my first floor would be framed with joists rather than using a slab,” he says.Scaglione can’t disagree with the functional advantages of a full basement built with concrete, rather than block, walls, but there’s a labor issue here as well. Scaglione is working by himself, and he doesn’t have access to concrete forms.With than in mind, Charlie Sullivan suggests ICFs for the foundation walls, “one of the easier solo building approaches if you don’t mind calling a concrete company to come fill them.” Scaglione could even do the entire first floor with ICFs, Sullivan adds.Scaglione has considered, and rejected, ICFs after seeing a fellow owner/builder bracing his ICF walls before the concrete was poured with metal forms he had to rent. Second, Scaglione wasn’t embracing the idea of having the expanded polystyrene foam of an ICF exposed on outside walls.An alternative suggested by James Morgan would protect the base of the framed wall with a peel-and-stick waterproof membrane (in red) and a masonry veneer outer layer. It’s a detail Morgan has used successfully for many years. All About Wall RotZen and the Art of GradingFlashing Brick VeneerGreen Basics: Foundation TypesHow to Insulate a Basement WallFoam Under Footings Wall rot actually is a common problemScaglione isn’t convinced that an 8-inch gap between ground level and the bottom of a wood-framed wall is enough. “I have seen sill plates rotting and water damage all over the place where I live,” he says. “I would say it is a widespread problem on houses that are less than 1 foot above grade. I think you’re right that the code doesn’t say 16 inches. The old houses that are in good shape around here all have at least an 18-inch-stem wall.”He first read about extending the height of stem walls in a book by Ben Falk, who said one of the most common problems in houses built in cold, humid climates was the interface of the foundation and the frame.Before buying his lot, Scaglione saw several houses that were rotting in this area. One house he remembers in particular was a timber frame built in the 1970s, with one corner about 8 inches above grade.“The [pressure-treated] sill was hanging in there, but they also put down a timber sill that was completed rotted away to the point that the house was sagging and there were gaps around the windows,” he says, “I want my house to last longer than 40 years.”Although replies posted to his original question suggest there are ways to detail a wall so melting snow drains harmlessly away, Scaglione still wonders whether adding two courses of 8-inch block and getting the walls that much farther away from the ground is, in the end, a simpler and more foolproof approach.“Just about every well built old house in this area has at least 16 inches of clearance above grade, and I don’t think those guys were stacking rubble for fun,” he says.

Canelo-GGG to MayMac fans: We’ve got a real show for you

first_imgGolovkin said he might watch the replay of Mayweather-McGregor this week, but didn’t seem terribly interested. Alvarez, who took his only career defeat against Mayweather in 2013, said he ordered the pay-per-view, but “to see a show, not a fight. I knew what I was getting.”“We weren’t negative on that event,” Loeffler added. “We just made it clear that this is the real boxing match, and that was a spectacle. It was the most popular MMA fighter against the most popular boxer. … You shouldn’t sell it as a real, competitive fight. But we were happy that it wasn’t a disaster to where people would be down on buying this fight.”Although Loeffler praises McGregor’s showmanship and MMA skills, he likened the matchup to Muhammad Ali’s infamous 1976 fight with Japanese pro wrestler Antonio Inoki.“It was really more of an exhibition,” Loeffler said. “It wasn’t really a boxing match.”But don’t mistake Loeffler for an Oscar-style hater. He thinks the long-term benefits of that short-term curiosity outweigh the drawbacks.“The more boxing exposure we can get for the sport in general, the more fights that can be made,” Loeffler said. “It brought (boxing) to the mainstream. It got a lot of attention that many other events never have a chance of getting. But I really think (Alvarez-Golovkin) is the highlight of boxing for this year.” But now that Mayweather’s farewell victory over the UFC champion went off without a major embarrassment for boxing, De La Hoya and fellow promoter Tom Loeffler hope their upcoming megafight between Saul Alvarez and Golovkin will be carried to new heights by a surge of interest created by the spectacle of the summer.If you liked Floyd and Conor, they think you’re going to love Canelo and Triple G.FEATURED STORIESSPORTSWATCH: Drones light up sky in final leg of SEA Games torch runSPORTSSEA Games: Philippines picks up 1st win in men’s water poloSPORTSMalditas save PH from shutoutGolovkin meets Alvarez on Sept. 16 in the same Las Vegas arena where Mayweather stopped McGregor in the 10th round last Saturday.

If there was a Canelo in there, obviously it would last one round.”ADVERTISEMENTlast_img read more

Sister’s blackmail, torture forced me to reveal my same-sex relationship: Dutee Chand

first_imgWomen’s 100 metre national champion Dutee Chand on Tuesday alleged that her eldest sister’s blackmailing and physical torture had forced her to come out in the open about her same-sex relationship.Dutee Chand, winner of two silver medals at the 2018 Asian Games, on Sunday became the first Indian sportsperson to admit being in a same-sex relationship with a girl from her hometown Chaka Gopalpur in Orissa.”My own sister is blackmailing me, she asked me for Rs 25 lakh. She had once beaten me, I’d reported to the police. Since she was blackmailing me, I was forced to come out about my relationship,” Dutee Chand told ANI.However, Dutee’s sister had her own version of the story as she had earlier alleged that the ace sprinter’s partner was pressurising her to get married and appealed to the government to provide protection and security to Dutee.”She is an adult. It’s her decision whether she wants to marry a girl or a boy. But Dutee has been forced to speak all this. Otherwise, a decision about marriage could have been discussed later,” Dutee’s sister Saraswati has said.After making the revelation two days ago, Dutee has faced expulsion from the family and her mother has refused to accept Dutee’s same-sex relationship.”Dutee wants to marry a girl, who is the daughter of my niece, so she is my grand-daughter. In this relation, Dutee will be like a mother of that girl. Then how will it be possible in our society in Odisha,” Dutee’s mother Akhoji told ANI.advertisementOn Tuesday, Hollywood’s popular comedian and talk-show host Ellen DeGeneres came out in support of Dutee. DeGeneres, who came out as a homosexual, over two decades ago on national TV, said she was proud of the Indian sprinter.She’s the 100m record holder and the first openly gay sportsperson in India.
