DeMarcus Cousins, Klay Thompson unlikely to play in 2019 FIBA World Cup

first_imgOAKLAND – Before they make their summer plans, the Warriors primarily are concerned about something else. Can they beat the Toronto Raptors in Game 6 of the NBA Finals on Thursday and force a Game 7?Nonetheless, at least two of the Warriors’ five All-Stars have some clarity on their offseason plans. Klay Thompson and DeMarcus Cousins are not expected to play with the U.S. Men’s national team for the 2019 FIBA World Cup from Aug. 31 through Sept. 15.“Probably not this year,” Cousins said …last_img read more

Five things we learned Tuesday at Raiders HQ

first_imgALAMEDA — Tyrell Williams has been about as low key as a prize free agent could be since joining the Raiders in March.Part of it is he signed four-year, $44.3 million contract with $22 million guaranteed on the first day of free agency not long after the Raiders agreed to send third- and fifth-round draft picks for Antonio Brown.Brown was like a total eclipse in terms of attention even when he wasn’t practicing for reasons ranging from frostbitten feet to a dispute over his helmet. …last_img read more

Is Oriented Strand Board as Impermeable as They Say?

first_imgThe Quirkiness of OSB: a Summer Camp presentationThe graph depicted in Image #2 (below) shows that the permeance of OSB is really low when the mean RH is low and that it doesn’t even reach 10 perms when the mean RH is 100%. That means it’s still a class III vapor retarder at best, whereas plywood, which gets up over 30 perms, becomes quite permeable as the air on one side gets more and more humid. So, plywood dries better than OSB, but how well do we really know OSB?At Building Science Summer Camp this year, Chris Timusk, a building science professor at George Brown College, gave a presentation called The Quirkiness of OSB (pdf).  He did his doctoral research on OSB and how well it deals with moisture. I’ve spent the past few days reading as much of his dissertation as I could, and I have to say, it’s a fascinating and well-written document. (Click to download pdf version.) Chapters 2-4 give the general background information on wood, OSB, and moisture and, I believe, are readable even by those without science degrees (although that would certainly help).Timusk saw the existing data on OSB and realized that we really didn’t know much at all about how well it handles moisture. For example, if you look at a graph of OSB permeance like the one above, you need to know what type of OSB it was. OSB comes with a range of densities, resin type and content, and surface treatments.So that was the first thing he wanted to look at. The table in Image #3 below (Table 5.1 in Timusk’s dissertation) shows the sample types that Timusk chose to study.His research project looked at two important moisture properties of OSB: permeability and sorption. The former, as stated above, tells you how much moisture moves through a material under a given set of conditions. The latter tells you how much moisture the material can hold as you vary the relative humidity. In this article, I’m going to discuss only his permeability results and will come back to sorption in a future article.The photo at the top of the page (Image #1) shows one of the samples he studied. The researchers manufactured the OSB themselves just for this experiment but did so in a commercial OSB plant, not in a lab. Then they cut it to various sizes and shapes and sealed the samples to the tops of cups, as shown in Image #4 below. They placed the cups in a chamber where they could control the temperature and humidity on the outside of the cup.In each cup was either water, for the wet cup results, or a dessicant, for the dry cup results. They would periodically weigh the samples and cups to see how much moisture they gained or lost. That allowed them to calculate permeability. Permeance and permeabilityPermeance, as shown in the graph above, is a number that tells you how much water vapor will move through a particular piece of material. Permeability tells you how much water vapor will move through a particular type of material. Permeance depends on thickness; permeability doesn’t. (For the science geeks out there, permeance is an extrinsic property, permeability intrinsic.) Another way to think of them is that permeance is like mass, and permeability is like density.The units of these two quantities aren’t very pretty, but I suppose you want to see them, don’t you? Here they are in imperial, or inch-pound (I-P) units:[permeance] = grain/square-foot·hour·inch of mercury, which we normally shorten to perms[permeability] = grain·inch/square-foot·hour·inch of mercury, which we shorten to perm-inchesDon’t say I didn’t warn you!

As you can see, plywood and OSB have about the same permeance when the mean relative humidity (RH) is low. But as the RH mean grows, so, too, does the difference between plywood and OSB in terms of their ability to move water vapor through from one side to the otherJoe’s recommendation: “The key seems to be an air gap between claddings and sheathings and an ability to redistribute moisture – typically facilitated by – yes, you guessed it – a gap.” Read his article for the full scoop on that; but in short, this is why we need vented rainscreens on homes sheathed with OSB. Relative humidity cycling and permeabilityIn addition to the samples with various densities, resin contents, or surface treatments, Timusk looked at two other variables. One was the result of taking the samples through repeated cycles of soaking in water and then drying. The other was cycling the samples through exposure to high relative humidity (100%) and then low RH (42%).About the latter, Timusk wrote in his dissertation, “The findings from the relative humidity cycled specimen are perhaps the most significant of all the tests conducted.” Why? Because repeated exposures to high relative humidity aren’t that uncommon.Image #6 shows the results for both the liquid and vapor wetting tests.As you can see, in both cases, the permeability of the OSB increased with repeated cycles of wetting. For soaking, it increases by nearly a factor of four. For exposure to humid air, it nearly doubles. Wow! How is OSB different?Oriented strand board is that flaky plywood you see on most residential job sites these days. (That’s a closeup of a piece in the photo above.) I toured an OSB plant several years ago and got to see how it’s made, from beginning to end — logs to 4’x8′ sheets. It’s pretty cool! To get a sheet that’s 1/2″ or 3/4″ thick, they start with a layer of chips (called strands) that’s about 6″ thick.OSB replaces the previously dominant sheathing material, plywood. The properties of these two materials, however, are not the same. Joseph Lstiburek, PhD, PE, wrote about the importance of recognizing the differences in his article, Mind the Gap, Eh? The article included a permeance graph (see Image #2, below).center_img Oriented strand board (OSB) gets blamed for a lot of problems that are really the fault of the designers and builders. Part of the problem, of course, is the perrenial confusion between correlation and causality. OSB hit the market as we really started getting serious about insulation and air sealing. As I described in the story of painters refusing to paint insulated homes, building assemblies that keep the exterior sheathing and cladding colder restrict its ability to dry. Is that the fault of the OSB? Or the insulation? Or the lack of a vapor barrier? Or something else altogether? Permeability resultsHere’s a quick look at the results of all the permeability tests they ran. The graph in Image #5 below (Figure 7.11 in Timusk’s dissertation) shows that there’s quite a lot of variation from the least permeable to the most permeable sample. Here are the main takeaways:Higher density is correlated with lower permeabilityThe OSB core is much more permeable than either the top or bottom surfaces.The more resin in the OSB, the lower the permeability.The more a sample has cycled through wetting and drying, the more permeable it is.There’s a huge difference (~6x) between the most and least permeable samples tested.Now, let’s look at the most interesting part of this research. How should we build with OSB?OK, so the main takeaway here is that we don’t really know how permeable the OSB we’re using is. If you’ve got a type that has higher density or more resin, your OSB may have a lower permeance than the material specifications say. If it has a lower density or has been soaked and dried or repeatedly exposed to high humidity, it probably has higher permeance than stated.What we do know, however, is that it’s still not as permeable as plywood. That means you should assume it needs some help drying out, so always follow the two main rules of moisture management:Don’t let susceptible materials get wet.Allow for materials and assemblies to be able to dry out after they do get wet.Flash the windows properly. Use overhangs. Install your cladding over a gap with a vented rain screen.Remember, there are three things that can cause a building to fail faster than anything else: rain, moisture, and water.

OSU lost, 64-49.Credit Shelby Lum / Photo editorThe Indiana Hoosiers came into their game against the Ohio State women’s basketball team undefeated and ranked in the top-25 for just the second time in team history.They left Assembly Hall with a loss to the unranked Buckeyes.OSU sophomore guard Ameryst Alston led all scorers and tied a career high with 29 points as the Buckeyes took down the No. 22 Hoosiers, 70-51, Saturday.Coach Kevin McGuff was not shy in his praise of his star guard after the victory.“She (Alston) was in attack mode for 40 minutes tonight,” McGuff said in a press release following the game. “We are a different team when she is playing with that type of aggressiveness.”The Buckeyes also got quality minutes from junior guard Raven Ferguson, who came off the bench to record a career-high 18 points.“This was Raven’s best game all year,” McGuff said. “She generated a lot of offense for herself and her teammates.”The efforts of Alston and Ferguson also made an impression on Indiana coach Curt Miller.“The one-on-one ability by Ameryst and the one-on-one ability by Raven Ferguson was the big difference in the game tonight,” Miller said in a postgame video for Indiana athletics. “They created havoc with their penetration.”The OSU defense was a big factor in the victory, as it held the Hoosiers to just 28.8 percent shooting from the field.“I thought we were particularly good on the defensive end today and I think our players did an excellent job executing what the game plan was and playing with great intensity,” McGuff said. “Our communication was better and we were just much, much better on the defensive end.”Another area of success for the Buckeyes was scoring inside, where the Buckeyes outscored Indiana 38-14 in the paint.“Ohio State’s big,” Hoosiers senior center Simone Deloach said in a postgame video. “They did a really good job of getting the ball inside and … passing out of the post too.”The game seemed to be in hand midway through the second half as OSU led 56-37 with 10:46 remaining.But the Hoosiers then scored 11 straight to cut the lead to eight with just more than eight minutes left.The crowd at Assembly Hall roared, but the Buckeyes had an answer.The Buckeyes finished the game on a 14-3 run in the final eight minutes to seal a victory, much to the delight of McGuff.“That was really great to see,” McGuff said. “They certainly could have crumbled and quit doing the things that allowed us to get the lead we had prior to that run.”The win over Indiana gave the Buckeyes their second road victory this season, the other coming against West Virginia Nov. 8 when they beat the Mountaineers 70-61.“We still have a long way to go,” McGuff said. “But this was a good performance for us.”OSU is scheduled to travel to Penn State Thursday.
