BIGDADDYKOOL, a top contender for the June 25 Cal’s Jamaica Derby, looks the one to beat when he takes on six fellow three-year-olds in the opening restricted allowance race (non-winners of two) over 1700 metres at Caymanas Park tomorrow. Trained by Anthony Nunes, BIGDADDYKOOL was a fast-finishing fourth (beaten 4-1/4 lengths) to FUTURE KING in the Post to Post 2000 Guineas over a mile on April 9, this after running miles wide into the straight. He has worked well in preparation for this race, and with the competition less than fierce, should have little difficulty in beating THE PROMISE LAND and company. Top apprentice Linton Steadman has the ride from the convenient mark of 53.0kg. TWILIGHT CITIZEN, a fast-finishing second to stable-companion to TRADITIONAL STORM over 1300 metres on April 23, is tipped to go one better in the second race over a similar trip to be contested by eight starters, including GOLD SCREW, who just failed to stave off TARANTINO over 1820 metres recently, and MINY LEE, who was third in that race. GOLD SCREW will have lots of supporters even with female apprentice Mellisa Ward replacing former champion jockey Wesley Henry, but the Carl Anderson-trained TWILIGHT CITIZEN, with apprentice AndrÈ Powell, only needs to get it right at the start to score an overdue win. The third race should provide the lightly raced RAWALPINDI EXPRESS with his maiden win on his fifth start. True, the five-year-old son of Coded Warning is proving expensive to follow, but with champion jockey Shane Ellis now taking the ride, the hint should be taken. IDON’TKNOW looks the principal danger in a seven-strong field over 1100 metres. Recent winner PRINCE O’SHAUN, now back over an ideal trip after flopping over the straight behind MIRACLE RECOVERY on April 24, looks nicely off at the weights (53.0kg) with 3.0kg claiming apprentice Bebeto Harvey, and should rebound with a win over 1500 metres.

The last two races in the first Super-6 should be won by AQUILO (Javanne Patterson up) and URBAN PRINCIPAL (Odean Edwards), both of whom finished second last time out. Their respective dangers are EL CLIENTE (Omar Walker) and DUSSELDORF, with Shane Ellis up.
A man sustained serious injuries to his head after being struck by a hammer in Letterkenny at the weekend.The man was set upon at around 1am on Sunday morning in the Pearse Road area, close to the Riverside apartments.A man is believed to have been attacked by two males, who used weapons, including a hammer, during the course of the attack. Garda Rafferty asked in a weekly community alert for anyone who lives in the area and who saw or heard anything to make contact with Gardaí at Letterkenny on 074-9167100 or the Garda Confidential Line on 1800-666-111.Gardaí are appealing for witnesses to two serious assaults in Letterkenny in the early hours of Sunday morning.It is not believed that the two are connected.At around 4.30am, a male was set upon at Oldtown Road. The man was waiting on a lift at Lower Main Street when he was approach by a group of makes and one female. He was verbally abused before being attacked at Old Town Road where he received ‘quite a few injuries’, Garda Rafferty said.Again, witnesses are asked to contact Gardaí at Letterkenny on 074-9167100 or the Garda Confidential Line on 1800-666-111.Man injured in Letterkenny hammer attack – two serious assaults at weekend was last modified: April 17th, 2019 by Chris McNultyShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:assaultGardaiHAMMERletterkennyLetterkenny GardaiOld Town RoadPearse Road
Sam Rashkin, until very recently the head of Energy Star for Homes, recently published Retooling The US Housing industry, a book of his opinions on, and suggestions of how to improve, the new home industry. The book is a fairly quick read with a great history of housing, and a good analysis of how the U.S. home building industry evolved to its current state.The book starts off with a recap of the financial crisis, and the involvement of the home construction industry in that crisis. While this is not new information to most people in the construction industry, a couple of statistics clarify the depth of our problems: In 2006, housing accounting for 6.2% of GDP; in 2010, that figure dropped to 2.4%, and we are not likely to see a full recovery soon, if ever.One major point with which I agree is that the long-promoted concept that everyone should own a home is no longer valid. Here’s a quote in the book from a 2010 Price Waterhouse study: “Not everybody can afford or should own a home.”History classThere are two separate history lessons in the book. The first covers the expansion of suburban development following WWII, encouraged by FHA and VA mortgage programs, that “discouraged renovation of existing housing stock, multifamily homes, and mixed use buildings.”The second is a timeline of developments in construction, starting with the Egyptians, and moving quickly into a brief recap of several key eras described as:• 1750 – 1850: Birth of a Nation• 1850 – 1920: The Industrial Revolution• 1920 – 1950: The Electric Grid Emerges• 1950 – 1985: Age of Cheap Energy• 1985 – Present: Building Science ArrivesEach of these sections includes descriptions of typical techniques of the era for Foundations, Framing, Materials, Insulation, Windows, Space Conditioning, Plumbing, and Electricity, providing a nice overview of the development of building technologies.Lessons not learnedOne key theme running through the book is best described by this section subtitle: “Key Lessons From Prominent Failures Have Not Been Learned.” In a parallel structure to the historical review sections, key failures and the lessons that should be learned from them in each building component are addressed.These include hardboard siding, urea formaldehyde in insulation, missing window flashing, and polybutylene pipe. This is followed by another review of very specific materials and techniques for each building component that, when employed properly, will lead to high-performance homes.The main takeaway is that builders need to invest in quality design and construction, which will result in high-performance homes. The big question is whether or not home builders will actually be willing to make these investments, or will they simply continue to do the same thing over and over again, make their money, and move on, rarely if ever worrying about how their homes perform over the long term?How long a warranty?Probably the most radical thing proposed in this book is the concept of builders providing a 30-year warranty on their homes. This isn’t quite as far-fetched as it might seem, as this extended warranty will require regular maintenance, quite like car warranties, which, if managed properly, can provide a steady income stream for businesses willing to take on this work.The book wraps up with a section on selling high-performance homes; the section provides a good outline on how to make the case for them to the consumer. I am not, however, hopeful that there will be enough of a market transformation, particularly in our currently troubled economy, to move the home building industry fast enough to make an impact.Thumbs upI found the book a fast read, with enough interesting information to keep me engaged through most of it.I am a little disappointed that our existing housing stock was not addressed at all, but that is clearly outside the scope of this book, and would probably fill a much larger volume. We can only hope that enough home builders will read the book and follow its recommendations as the industry begins to recover.
Citation: Astronomers detect a fast rotating group of stars in our galaxy (2016, November 16) retrieved 18 August 2019 from https://phys.org/news/2016-11-astronomers-fast-rotating-group-stars.html Explore further The discovery was made by a team of researchers led by Jason Hunt of the University College London, U.K. They have combed through the Tycho-Gaia astrometric solution (TGAS) data included in data release 1 (DR1) from ESA’s Gaia satellite. The spacecraft is completing a survey of one billion stars in our galaxy and local galactic neighborhood, measuring their positions with an accuracy of microarcseconds.”We wanted to examine the speed with which the stars rotate around the Galaxy, and for that, we need velocity in three directions. We have never been able to explore local galactic dynamics in such detail because very few stars have had reliable distance estimates. This first data release provides distance estimates for around 2 million stars in the solar neighbourhood, and the next data release will have over one billion! This is a substantial improvement on the previous mission, Hipparcos, which provided measurements for about 150,000 stars,” Hunt told Phys.org.He noted that this fast rotating group of stars was difficult to pick out because Gaia DR1 only provides velocities in two directions across the sky, and not line-of-sight velocity toward and away from us. However, by looking directly toward or away from the galactic center, it was possible to approximate the rotation velocity.The astronomers calculated that the newly detected group of stars is rotating faster than the sun by about 20 km s−1. Moreover, they found that the stars in this fast rotating group are rotating significantly faster than the mean rotation of the stars.Trying to explain these distinct velocities, the team assumed that they are caused by one of the two major spiral arms of the Milky Way – the Perseus Arm. The results indicate that stars which are behind the spiral arm, and at the pericenter of their orbits, experience an extended period of acceleration from the gravitational potential of the Perseus Arm.”This extended period of acceleration causes them to move significantly faster than the other stars. We also know that this will either occur at one point along the spiral arm if the arm moves as a wave with a constant pattern speed through the disc, or it will occur all along the arm if the spiral arm moves with the same velocity as the stars, which is predicted by computational models based on the gravitational interaction of stars, called N-body simulations,” Hunt said.The team’s research supports both of the competing theories of spiral arm dynamics mentioned by Hunt. However, it favours slightly the theory seen in N-body simulations in which the arm moves with the same speed as the stars, because the scientists found that the feature remains unchanged at increasing distance from the sun.”The quantity of data and the observational errors involved mean we cannot say for certain whether this is the case. We cannot observe further along the arm with the current data,” Hunt noted.The scientists hope that data shedding some new light on this case could be delivered by Gaia’s data release 2 (DR2), scheduled to be published in November 2017. The increased quantity and quality of data in DR2 will allow the researchers to observe further along the spiral arm and determine whether this group is present along the entire spiral arm, or present towards the galactic anti-center.”If it’s present all along the arm it will be strong evidence for the type of transient reforming spiral arm created in the models, and if it is only present just outside the solar radius where we observed it in this work, it will be strong evidence for the theory that spiral arms travel as density waves through the disc,” Hunt concluded. © 2016 Phys.org Virtual Milky Way Barred Spiral Milky Way. Illustration Credit: R. Hurt (SSC), JPL-Caltech, NASA (Phys.org)—European astronomers have spotted a group of stars with high rotation velocity residing outside the solar radius in our Milky Way galaxy. According to a paper published Nov. 2 on arXiv.org, this group, which moves significantly faster than the majority of other stars, could provide essential information about stellar dynamics.
