Hammer & Hand, a well-known construction company in the Pacific Northwest, has posted its Best Practices Manual online.Used by Hammer & Hand carpenters in the field, the guide includes 180 step-by-step illustrations on dealing with a range of details, including crawl spaces, rainscreens, window installation, and wall penetrations.“We’re launching this section of our site in the spirit of collaboration,” co-owner Sam Hagerman wrote. “The details contained within have been developed through extensive in-the-dirt experience and informed by our building science training and research. They’re details that we have found combine durability, performance, and constructability in our Pacific Northwest climate.”The company, founded in 1995 by Hagerman and Daniel Thomas, has offices in both Portland, Oregon, and Seattle, Washington, where it’s housed in the Bullitt Center. The company has tackled a variety of high-performance, high-end designs, including projects built to the Passivhaus standard, and also makes custom wood doors for Passivhaus buildings.Hammer & Hand has won a number of awards, including Custom Builder of the Year in 2014 from Earth Advantage.

Magnetic Media spoke to Ralph Higgs, the TCI Tourist Board director who assured that the country’s cruise and dive capital is fine. “So in time, Grand Turk as I said will be restored and people will continue, particularly our cruise passengers, will continue to patronize Grand Turk. Grand Turk is still one of the most popular cruise destinations…” Cruise figures forecast to drop, says Tourism Director Minister of Works puts government buildings reconstruction post hurricanes at $8.6m Facebook Twitter Google+LinkedInPinterestWhatsApp
A simulation of dark matter filaments across the universe. Zarija Lukic/Lawrence Berkeley National Laboratory Dark matter is an enigmatic beast. We can’t see it, yet we know it makes up most of our universe. Finding the mysterious particle (or particles) the exotic matter is composed of has puzzled and intrigued scientists for decades. On June 6 at the Planck 2019 conference, an international meeting highlighting frontier physics research, John Terning and Christopher Verhaaren, theoretical physicists at the University of California, Davis, presented a new theory for what makes up dark matter and how we might detect it. A preprint paper of their study was uploaded to the arXiv directory on May 31. Dark matter and dark energy, two theoretical forms of matter, are thought to make up more than 85% of the known universe. When we look out into space, the evidence for the existence of dark matter is plentiful — we can see the effect it has on gravity and the expansion of the universe. We know something, an invisible particle perhaps, is lurking out of sight and responsible for the way our universe works. Scientists have long struggled to find the elusive, exotic particle that makes up dark matter, and more theories abound every year. In December, an Oxford scientist proposed that the universe was made up of a dark fluid. Others have suggested hunting for dark matter in cutting-edge new ways. Still, we have failed to detect it.Which brings us to Terning and Verhaaren’s idea. They argue for a new “type” of dark matter and a way to detect it, a one-two punch of theory and experimental validation. However, the authors of the study caution that verifying it could take quite some time. The new type of dark matter is different from previous theories, which suggest the exotic, invisible particles may be made up of weakling interacting massive particles, or WIMPs. No experiments have been able to find these particles, though scientists have built large, shielded laboratories that hope to reveal them. “We still don’t know what dark matter is,” said Terning in a press release. “The primary candidate for a long time was the WIMP, but it looks like that’s almost completely ruled out.” The private rocket company trying to send Australia to… See SLAC, a two-mile particle accelerator next to Stanford 2 3:17 Share your voice Comments The researchers looked at an opposing theory for dark matter with an equally fantastical name: “dark electromagnetism.” It says there’s a subatomic particle known as a dark photon which sometimes interacts with regular photons that we can already detect. The duo added their own spin to the idea by showing dark matter might be caused by “dark monopoles,” which are based on quantum theory.It all gets very tangled here, especially for us mere mortals struggling with everyday physics. The bottom line? We’ve got a new theory which proposes the “dark monopole” could be detected in an experiment thanks to its interactions with regular photons and the Aharonov-Bohm effect, which has been proven experimentally. However, the observable effect would be incredibly small — even smaller than gravitational waves — and we don’t yet have the technology to detect such minute signals right now. Alan Duffy, a dark matter researcher at Swinburne University in Australia, notes how the first detection of gravitational waves (itself only a theory until recently) took “a century of heroic scientific and engineering effort” suggesting that might be “a worry for the testability of the [new] prediction.”Where does that leave Terning and Verhaaren’s theory? Well, as a theory, of course. But that’s where all good science starts. Tags 33 Photos Now playing: Watch this: Sci-Tech
[Representational image] Creative CommonsDirect tax collections in the first five months of the current fiscal increased 17.5 per cent to Rs 2.24 lakh crore, mainly on account of income tax mop-ups from individuals rising.The report said that the collections in the April-August period constitute 22.9 per cent of the total budget estimates of direct taxes, which comprise personal income and corporate tax, for the current financial year 2017-18.”The direct tax collections up to August 2017 continue to register steady growth. Direct tax collection, net of refunds, stands at Rs 2.24 lakh crore which is 17.5 per cent higher than the net collections for the corresponding period of last year,” a finance ministry statement said on Monday.The statement said that growth rate for Corporate Income Tax (CIT) and Personal Income Tax (PIT), including Securities Transaction Tax, in terms of gross revenue collections was 5 percent and 16 percent respectively.Refunds amounting to Rs 74,089 crore were issued in the period from April 2017 to August 2017, which were 7.2 percent lower than refunds issued during the corresponding period of 2016-17, the finance ministry statement said.However, after adjusting for the refunds, the net growth in CIT collections was 18.1 percent while that of PIT collections was 16.5 percent.In the April-August period of the previous fiscal, 2016-17, direct tax collections had grown 15.03 per cent to Rs 1.89 lakh crore.
