DeWalt Portable Power Station Battery Inverter Review

With the ability to handle the inrush load of a table saw, DeWalt’s popular Portable Power Station is the only battery inverter we’ve used that can make your entire jobsite cordless. The DeWalt Portable Power Station battery inverter and charger tosses its watts right in with several others we’re reviewed recently. It’s a very different animal than other battery-powered inverters with very real benefits on the jobsite. With the ability to handle the inrush load of a table saw, DeWalt’s popular Portable Power Station is the only battery inverter we’ve used that can make your entire jobsite cordless. It offers fewer total watt-hours than some of its competitors, but then again, DeWalt didn’t make this for preppers who want to maximize them. Charge time is also a bit slow and DeWalt makes a dedicated charger that works faster if that’s what you need. Its modified sine wave output defines it as an excellent jobsite option but you’re better off with a pure sine wave inverter for charging electronics.

A snake moves without legs by the scales on its belly gripping the ground. It generates

A snake moves without legs by the scales on its belly gripping the ground. It generates friction at the points needed to move forwards only and prevents its scales from being worn off by too much friction. Researchers of KIT have found a way to transfer this feature to components of movable systems. In this way, durability of hip prostheses, computer hard disks or smartphones might be enhanced. Their results are published in the journal Bioinspiration & Biomimetics. googletag.cmd.push(function() { googletag.display(‘div-gpt-ad-1449240174198-2′); }); “Friction and wear are two of the biggest challenges in systems of several individual components,” Christian Greiner of the Institute for Applied Materials says. A solution is found in nature: Snakes, such as the ball python, or lizards, such as the sandfish skink, use friction to move forwards, but can reduce it to a minimum thanks to their scales. Together with Michael Schäfer, Greiner developed a process to transfer the scale structure of reptiles to components of electromechanical systems: With a fiber laser, they milled scales into a steel bolt of 8 mm in diameter. Wih the help of two different struct...

Our view: King’s new chapel an example of preservation done well

Luzerne County boasts a glut of neglect. On Thursday, King’s College unveiled a stellar example of the exact opposite. We spent millions to save the Hotel Sterling before razing it. We made big plans for the historic Huber Breaker before selling it for scrap. For every gem we save, we scrap a dozen (look no further than the county’s lost churches). Even when the value of a place is visibly priceless, we are unable to conjure the will to save it. The distinctive architecture of the Irem Temple in Wilkes-Barre made it a no-brainer for the top ten in any preservation list. Yet it had to fall into a state of disrepair until efforts to save the building began. On Thursday, King’s showed not only how to preserve an historic building but why. Former members, their friends and families came by the score to share memories of time spent in the 147-year-old edifice, and to take in the remarkable job the college did restoring it to new life as the school’s chapel. It has been 11 years since the Memorial Presbyterian Church closed, and eight years since King’s bought the property without a clear vision for it. But it turned out to be time well spent. Carpets disappeared from the floors, the...

How YACHT fed their old music to the machine and got a killer new album

The dance punk band YACHT has always felt like a somewhat techy act since debuting in the early 2000s. They famously recorded instrumental versions of two earlier albums and made them available for artists under a Creative Commons license at the Free Music Archive. Post-Snowden, they wrote a song called “Party at the NSA” and donated proceeds to the EFF. One album cover of theirs could only be accessed via fax initially (sent through a Web app YACHT developed to ID the nearest fax to groups of fans; OfficeMax must’ve loved it). Singer Claire L. Evans literally wrote the book (Broad Band) on female pioneers of the Internet. So when Evans showed up at Google I/O this summer, we knew she wasn’t merely making a marketing appearance ala Drake or The Foo Fighters. In a talk titled “Music and Machine Learning,” Evans instead walked a room full of developers through a pretty cool open secret that awaited music fans until this weekend: YACHT had been spending the last three years writing a new album called Chain Tripping (out yesterday, August 30). And the process took a minute because the band wanted to do it with what Evans called “a machine-learning generated composition process.” “I ...

Young Man Who Got Dreadlocks Cut by Crushers Club Founder Defends Her Against Ava DuVernay

A Chicago-based youth organization continues to face backlash over photos of its white president cutting off teenagers’ dreadlocks. Sally Hazelgrove, the founder of the Crushers Club, captioned one of the images: “And another Crusher let me cut his dreads off! It’s symbolic of change and their desire for a better life!” Perhaps Jay-Z, Meek Mill, Meghan Trainor, Vic Mensa, and Rapsody can ask Sally Hazelgrove about her thinking behind the encouragement to cut off young Black male dreads. pic.twitter.com/GW59UuRgpJ The photos were posted nearly three years ago, but resurfaced this week after Roc Nation and the NFL announced a $200,000 donation to the Crushers Club as part of the Inspire Change program. The images, which were shared on the club’s official Twitter account, were immediately criticized as racially insensitive, as they implied black people had to conform to white beauty standards to achieve a “better life.” The criticism was amplified by a slew of other controversial tweets, including one that included the phrase “All Lives Matter”—a term commonly used among opponents to the Black Lives Matter movement. Sally Hazel...

Where There’s Waste There’s Fertilizer : Environment : Nature World News Where There’s Waste There’s Fertilizer : Environment : Nature World News

May 15, 2019 – We all know plants need nutrients, especially nitrogen and phosphorus. To give crops a boost, they are often put on fields as fertilizer. But we never talk about where the nutrients themselves come from. Phosphorus, for example, is taken from the Earth, and in just 100-250 years, we could be facing a terrible shortage. That is, unless scientists can find ways to recycle it. Scientists at Tel Hai College and MIGAL Institute in Israel are working on a way to make phosphorus fertilizer from an unlikely source — dairy wastewater. Additionally, they are taking the element from the wastewater with another unlikely character. They are using the leftovers that comes from making clean drinking water, which contain the element aluminum. “The material left after purification, called aluminum water treatment residue, is normally taken to a landfill to be buried,” says Michael “Iggy” Litaor, who led this work. “We changed this material by mixing it with dairy wastewater rich with phosphorus and organic matter. We then found it can be just as good as common fertilizers.” The benefits of the practice could go beyond recycling the e...

Know Your Options for Foaming Sheet : Plastics Technology

Tandem extrusion of PS is still the standard technology, but new materials options and equipment technology are emerging. Tandem extrusion lines are still preferred for PS foam processing because they provide very high output rate and more desirable cellular structure. In tandem low-density foam extrusion, the two connected extruders have quite different functions. The primary extruder (top) works to melt and homogeneously mix the materials, including additives and reclaimed pellets. The secondary extruder cools down the melt prior to foaming in order to optimize melt strength and strain-hardening behavior. The primary extruder in a tandem line is frequently equipped with a pineapple mixing section (or a Saxton mixer) to improve distributive mixing Cell population density is proportional to the number of impurities incorporated in the melt. Talc is the most commonly used cell nucleating agent for foaming but must be used sparingly. Pressure-drop rate also plays an important role in determining cell population density. Image: C. B. Park et al., Polymer Engineering Science (1995) Melt-temperature control is crucial to maximize the foam expansion ratio. If it’s too high, considerab...

Seahawks season is back! Here are the best cheap food deals you can find at CenturyLink Field

Seahawks season is finally upon us! If you haven’t already broken the bank buying tickets, we hate to say it, but you might end up breaking it while buying food at the game. CenturyLink Field has many local food options, including Beecher’s, Ivar’s and Din Tai Fung, but while delicious, they can get pretty pricey. To put that in perspective, when we told one of our sports editors that we were going to try to find cheap food options at a Seahawks game, he immediately started laughing and said, “Yeah … Good luck.” But alas, our investigative skills and young, broke millennial instincts prevailed, and we were able to find a few good deals. Before you go, know the stadium’s outside food policies. You can bring in outside food in a clear plastic bag, or pizza in a pizza box, according to the CenturyLink Field website. The only outside beverages allowed are sealed plastic water bottles — plain water only, with no flavors or carbonation. If you plan to bring food in, be aware of the NFL’s Clear Bag Policy, which limits each fan to one large, clear bag for carrying food or personal items. You can also carry a small clutch bag about the size of a hand or smaller. Candy or peanuts: A bag...
