Birds of a feather were flocking outside at AURA Music Festival over the weekend. During Pink Talking Fish’s set on the festival’s opening Thursday night, pianist Holly Bowling joined the Pink Floyd/Talking Heads/Phish tribute band for a rousing version of Phish’s “Weekapaug Groove” to close out their set.Bowling is coming off a year in which she released Distillation Of A Dream: The Music Of Phish Reimagined For Solo Piano and embarked on her first headlining tour, cleverly adapting Phish’s catalog in a way we haven’t heard it before. Likewise, Pink Talking Fish are coming off a red hot workman-like 2015, really solidifying a name for themselves as one of the premier tribute bands in the scene.You can watch a good portion of PTF’s set from AURA including Bowling’s sit in below:And listen to full audio of the show, below:Setlist: Pink Talking Fish at AURA Music Festival, Live Oak, FL – 3/3/16Set: Shine On You Crazy Diamond> Nothing But Flowers> Moma Dance, Mother, Burning Down The House, Mike’s Song> Dogs> Psycho Killer> Dogs> Once In A Lifetime> Weekapaug Groove** with Holly Bowling
WEST Indies U-15 batsman Mavendra Dindyal spanked a huge half-century to lift the Floodlight U-15 team to a 22-run victory against home side, Demerara Cricket Club, in a special 30-over battle in honour of coach Huburn Evans on Friday night under lights.The former senior national coach and national selector had travelled with the Floodlight junior team to Florida and had been instrumental in their admirable performance.In their latest clash, the Floodlights side, made up of a number of top youth cricketers, including national U-15 captain Zachary Jodah, national all-rounder Alvin Mohabir (captain of the side) and Dindyal, lost the toss and were asked to bat.Except for fellow opener Jodah, who worked the singles well (17) in a score of 24 and Mohabir (14 runs), none of the other batsmen threatened. Dindyal though, did not waver as he spanked seven fours and six sixes in a top score of 94. Romeo Deonarain, who eventually had the GCC batsman stumped, was one of three home team bowlers to have picked up two wickets.Young Jayden Dowlin and Mahiem Khan finished with 2-17 from four overs and 2-44 from six respectively, which helped to restrict the visitors for 173-9 in their allotted overs. In reply, the home team did not get on top of the bowling, as leg-break bowler Nityanand Mathura delivered. Mathura, who got the top wicket of opener Jaden Campbell for 60, finished with 4-31 from six overs.Campbell had the home team supporters on their feet as he spanked five fours and a six in his innings, but except for 19 (2×4) from Premkumar Permaul and 20 unbeaten runs from Wavell Allen, none of the other batsmen got into double digits, which limited DCC to 151-8 off their allotted overs.
What a dizzying week it’s been for Nike.After the company used the high-profile mug of former San Francisco 49ers quarterback Colin Kaepernick in its 30th annual “Just Do It” ad campaign, an angry President Donald Trump joined a lot of other angry Americans in expressing their displeasure with Nike for honoring a guy who took a knee during “The Star-Spangled Banner.” It seemed all doom and gloom for the sneaker maker.But that was Monday.On Friday, San Francisco-based Edison Trends dropped …

And why do so many homes have a long stairway between the front door and the bedrooms?Two typical answers to these questions would be, “because that’s the way we’ve always built houses” and “because these houses meet code.” (Those two reasons happen to be pretty weak, by the way.)We’re all getting older, and many of us have family members with special needs. Ideally, the homes we build today will work well for people with a wide range of abilities. Designing buildings that can meet the needs of people with varying abilities is called “universal design.”Most families have members with special needs; for example, my sister-in-law Caryn is blind. Caryn’s not a complainer, but I’ve learned a lot from Caryn about sidewalks. Some sidewalks are easy for blind pedestrians with canes to navigate; others are unsafe. Ideally, sidewalk surfaces should be consistent and predictable, with as few bumps and hard-to-interpret transitions as possible.Universal design strives to make buildings easy for a wide variety of people to use, including older people and people with disabilities. As much as possible, universal design attempts to meet the needs of people of all ages, sizes, and abilities.A house that follow universal design principles often aims for “visitability” — including ease of use by friends in wheelchairs — and aims to accommodate owners planning an “aging in place” retirement. A house built to universal design principles should make it easy for the owners to live independently in their home for as long as possible.Features that fall into the “universal design” category should be usable by a wide variety of people of different sizes and abilities.

Making concrete bendTo develop ductile concrete, our laboratory borrowed ideas from nacre, also known as mother of pearl — the iridescent material on the inside of abalone shells.Mollusks make nacre from aragonite, a natural form of calcium carbonate, which by itself is extremely brittle. But nacre is ductile because of its architecture at the nanoscale, which looks like a brick wall. The “bricks” are thin layers of aragonite platelets, and the “mortar” between them is a natural polymer that is very elastic. The polymer holds the rigid aragonite layers together, but allows them to slip from side to side under stress. This structure makes nacre both strong and flexible.Concrete is a composite mixture that normally consists of gravel and sand particles bound together with cement. To design ductile concrete, we imitated nacre’s “give” by dispersing tiny fibers inside the composite. When properly controlled, the interfaces between fibers and cement recreate the controlled slippages in nacre.Nacre, the coating on the inside of abalone shells, is highly ductile, allowing the shell to resist impacts without fracturing. It protects abalone from sea otters that try to break shells open by banging them on rocks.We call the resulting ductile concrete engineered cementitious composite (ECC) or strain-hardening cementitious composite. It can deform up to 3% to 5% in tension before it fails, which gives it 300 to 500 times more tensile strain capacity than normal concrete. This allows a slab of it to undergo a lot of bending without fracturing into pieces, earning it the nickname of flexible or bendable concrete.ECC was invented at the University of Michigan, and it has now acquired a following of hundreds of universities and industrial entities conducting further engineering research and technology development. Spring construction season is underway, and many tons of concrete will be used in the coming months. Unfortunately, concrete is a brittle material: Placed under stress, it cannot bend very far before it fractures. Some pavements that are being poured now will crack within a few years and require expensive repairs. New concrete will be mixed, and the cycle will start again.But a better solution is in view. My laboratory at the University of Michigan, along with many other laboratories around the world, has shown it is possible to make concrete more ductile — that is, bendable without fracturing. Bendable concrete makes infrastructure safer, extends its service life and reduces maintenance costs and resource use.Civil infrastructure very rarely fails because it lacks compressive strength — the ability to bear loads that push it together, as when columns support the weight of a building. Most failures occur because structures do not have enough capacity to carry tensile load — the ability to deform or stretch without rupturing – even though steel reinforcements often are added to concrete to prevent catastrophic structural failure. Researchers Claim to Develop a Concrete AlternativeReinventing ConcreteCarbon Emissions By the Construction Industry Uses for bendable concreteMaking concrete bendable addresses several of conventional concrete’s key flaws. First, suppressing brittle fracture prevents the formation of wide cracks that allow water and other aggressive agents like road salt to penetrate easily into concrete structures and attack their reinforcing steel.Experimental evidence and our theoretical calculations show that it is possible to extend the time it takes for chloride from road salt on a bridge deck surface to reach and corrode reinforcing steel from years to tens of years. A number of projects, ranging from patch repair to link slabs on bridge decks that dramatically extend service life, have taken advantage of this fracture suppressing ability.Bendable concrete also enables structural elements to absorb a lot of energy. For example, manufacturers have developed ECC dampers to retrofit the 28-kilometer Seisho Bypass viaduct along Japan’s eastern seaboard and to help make new tall buildings more resilient during earthquakes, including several in Tokyo and Osaka. Flexible concrete has many other potential large-scale industrial applications, including water infrastructure and underground construction.Widespread use of ECC will require a good supply chain and intelligent use of the material to optimize cost economics. The most significant obstacle is the fact that ECC is still relatively novel to structural engineers, who are trained to assume that concrete cannot withstand tension. Many serious concerns about the woeful state of U.S. infrastructure can be traced back to concrete’s brittleness. Cracks in concrete can reduce a structure’s usable life. They also weaken it and make it less resilient against natural forces, such as earthquakes or tornadoes, or man-made forces, such as bomb blasts in terrorist attacks.For example, 52 people died in the 1989 Loma Prieta earthquake in Northern California due to building and freeway collapses. Major freeways also sustained heavy damage in the 1994 Northridge earthquake in Los Angeles, including one that had been rebuilt after a quake in 1971. If the quake had occurred during a weekday rush hour, rather than at 4:30 a.m. on a Monday holiday, the results could have been catastrophic.Repeated infrastructure repairs and rebuilds use enormous quantities of materials and energy. Studies have shown that the carbon and energy footprints of frequent repair events, and the social and economic costs they generate, far exceed those associated with initial construction. We all pay these costs in time stuck in traffic jams, higher taxes and polluted air. Victor Li is a professor of engineering at the University of Michigan. This post originally appeared at The Conversation. How bendable concrete can heal itselfOur concrete composite can also learn new tricks. For example, when it is damaged, the hairline cracks that form can undergo healing just through exposure to water and air. Self-generating reactions create healing products through continued hydration and carbon mineralization, binding crack surfaces together in much the same way that our skin heals from a paper cut. Self-healing concrete can make structures such as roads and bridges more durable.Bendable concrete also can adjust its own thermal capacity, so that it stores more heat when the outside temperature is high, keeping building interiors cool. Encapsulated micron-sized wax-like materials within the concrete change from solid to liquid form, like tiny ice cubes melting into water, when temperatures reach levels that are uncomfortable for humans.We are currently teaching ECC to neutralize pollutants, thereby helping to maintain clean air in urban environments. Embedded nano-titanium particles in the composite break down pollutants into harmless substance via reactions catalyzed by sunlight.These autonomous and adaptive functional features can contribute to the development of future smart cities with infrastructure that responds to environmental changes. Our goal is to create a new generation of smart, bendable concrete that will help build and maintain a resilient, sustainable and healthy living environment. RELATED ARTICLES

State Rep. Mary Whiteford today celebrated the signing of her first bill Wednesday by bringing local treats to share with her colleague.10.16es in Lansing.It’s a tradition in the Michigan House of Representatives for a lawmaker to bring a gift from his or her district to celebrate the first time that the governor signs a bill they’ve sponsored.Rep. Whiteford passed out bags of apples from Overheiser Orchards, hard cider from Mackintosh Orchards and Oval Beach Blonde Ale from Saugatuck Brewing Company.“I was so happy to be able to share some of these awesome Allegan County products with my peers,” said Rep. Whiteford, R-Casco Township. “These are some of my personal favorites from our community and I’m so thankful for these donations from local businesses.”Rep. Whiteford’s first bill is part of a package of bills that defines the term veteran in Michigan law. The previous definition conflicted with the federal definition and lawmakers sought to bring unity to the term to ensure veteran benefit eligibility. House Bill 5548 is now Public Act 216 of 2016.### 10Nov Rep. Whiteford celebrates her first bill signing the Allegan County way Categories: Whiteford News
