MONTREAL – The historic cemetery atop Montreal’s Mount Royal offers a tranquil space for the dead to rest — but management says the living aren’t being granted the same courtesy thanks to speeding cyclists who are soon to lose their privileges.The 166-year-old non-profit that manages the cemetery recently announced it would ban bicycles from the picturesque spot as of Aug. 1., citing “flagrant disregard of the safety of pedestrians and of the character of the cemetery” by certain cyclists who use the sacred ground for “high speed training and other aggressive sports.”In a statement on its website, cemetery management said it had sought to avoid a ban by repeatedly bringing up its concerns with cycling groups.“We regret that these efforts have been unsuccessful and that we now must in the interest of safety proceed to a prohibition on cyclists, as we have previously indicated would be the consequence of failure to respect the rules,” the statement read.But the news isn’t sitting well with some of the city’s cyclists, who said they’re being punished for the bad actions of a small group.As the cemetery buzzed with cars, electric scooters, dog walkers and picnickers enjoying the perfect Saturday weather, some cyclists who paused from their training wondered why they were being singled out.“I find the cars much more dangerous than the cyclists,” said Therese Ryan, a local cyclist who has been coming to the cemetery for 25 years.She pinned the problem on a small number of elite cycling clubs, who train in large groups and at high speeds.But she said it’s unfair to ban regular riders from a “famous and lovely spot” that is beloved by all Montrealers, especially since the cemetery’s winding hills and leafy pathways are one of the few spaces where average riders can train without many cars whizzing by.Patrick Prevost, a nearby resident who rides over the mountain on a near-daily basis, agreed.“It’s pretty much the only green spot we have (to cycle) within the city limits,” he said as he paused on his ride. “It’s quiet, it’s peaceful, it’s fun to be here and there’s not many cars.”Prevost said he would be in favour of adding speed bumps and signs to slow down the truly fast riders, but argued the vast majority of cyclists are respectful.“The cemetery should be available to everybody: runners, bikers, walkers whatever, as long as everybody respects everybody, and I think everybody does respect the grounds.”But two other cyclists who rode through the cemetery on Saturday said they believed the ban was the right call, even though they were sad to lose one of their favourite spots.Lyne Raymond and Chantal Bergeron, who rode up the mountain together, said even they sometimes feel intimidated by the groups of competitive cyclists who blow by them at high speed.“They don’t stop, they’re cycling very fast, they’re not respectful of those (who are) in the cemetery to be there to take time with their family,” Bergeron said.Raymond agreed, noting that a high-speed cyclist had almost forced her off the path that very morning.“It’s very sad, but I understand the decision,” she said.

Gail Delaughter Traffic on the Katy Freeway feeder road.According to the study from the National Transportation Safety Board, about 27% of crashes around the U.S. can now be blamed on speeding. That’s not much less than the 29% that result from driving drunk.Kara Macek with the Governors Highway Safety Association says speeding just doesn’t have the same social stigma.“Of course if you’re going 90, 100 miles per hour that may raise some eyebrows,” adds Macek. “But by and large people do it.”To get people to slow down, the NTSB study says there has to be more enforcement. That includes things like speed cameras which are currently banned here in Texas.Macek says road design can also encourage people to drive too fast.“We’ve kind of designed and engineered our roadways into a system that prioritizes moving vehicles very quickly,” explains Macek. “And not necessarily taking into account the vulnerable road users — bicycles, pedestrians, motorcycles.”According to TxDOT’s figures from 2016, there were close to 28,000 crashes around the state where drivers were under the influence of alcohol or drugs. Speed was a factor in over 26,000 crashes. 00:00 /01:05 Listen X To embed this piece of audio in your site, please use this code: Share
By MARTIN CRUTSINGER AP Economics WriterWASHINGTON (AP) — Treasury Secretary Steven Mnuchin said Wednesday the redesign of the $20 bill to feature 19th century abolitionist leader Harriet Tubman has been delayed.The decision to replace Andrew Jackson, the nation’s seventh president, with Tubman on the $20 bill had been made by Mnuchin’s predecessor, former Treasury Secretary Jacob Lew, who had served in the Obama administration.Treasury Secretary Steven Mnuchin, however, said the delay in unveiling a $20 redesign had been prompted by thedecision to redesign the $10 bill and the $50 bill first for security reasons.Tubman’s fate had been in doubt since the 2016 campaign based on critical comments by then-candidate Donald Trump, who branded the move an act of “pure political correctness.”Mnuchin, however, said the delay in unveiling a $20 redesign had been prompted by the decision to redesign the $10 bill and the $50 bill first for security reasons. He said those bills will now be introduced before a redesigned $20 bill.Mnuchin made the announcement of the delay in response to questions from Rep. Ayanna Pressley, D-Mass., during an appearance before the House Financial Services Committee.In this May 22, 2019 file photo, Treasury Secretary Steven Mnuchin testifies before the House Committee on Financial Services on Capitol Hill in Washington. (AP Photo/Carolyn Kaster, File)The unveiling of the redesigned $20 bill featuring Tubman, famous for her efforts spiriting slaves to freedom on the Underground Railroad, had been timed by the Obama administration to coincide with the 100th anniversary in 2020 of passage of the 19th amendment giving women the right to vote.“Currently our currency does not reflect the diversity of people who have contributed to our great American history,” Pressley told Mnuchin.Mnuchin would not say whether he supported keeping Tubman on the redesigned $20. He said under the revised timeline, that decision will be left to whoever is Treasury secretary in 2026.Mnuchin said the redesigned $20 bill will not come out until 2028 which he said means that a final design for that bill will not be announced until 2026.He said the redesign of the bills was being done to introduce new security features to make it harder for the bills to be counterfeited. Based on the security issues, it had been decided to introduce redesigned $10 bills and $50 bills ahead of the $20 bill.“It is my responsibility to focus on the issue of counterfeiting and the security features,” Mnuchin said.During the 2016 campaign, Trump had praised Jackson for his “history of tremendous success” and suggested that Tubman could be placed on a different bill such as the $2 bill.Lew had arrived at the decision to displace Jackson on the $20 bill after first generating a loud outcry with his initial proposal to put a woman on the $10 bill, replacing Alexander Hamilton.Fans of Hamilton, a group that had grown with the popularity of the hit Broadway musical, felt it would be wrong to take him off the nation’s currency.
Citation: Researchers discover ultrathin lipid coating covering snakeskin (2015, December 9) retrieved 18 August 2019 from https://phys.org/news/2015-12-ultrathin-lipid-coating-snakeskin.html More information: Evidence of a molecular boundary lubricant at snakeskin surfaces, Journal of the Royal Society Interface, Published 9 December 2015.DOI: 10.1098/rsif.2015.0817 , http://rsif.royalsocietypublishing.org/content/12/113/20150817AbstractDuring slithering locomotion the ventral scales at a snake’s belly are in direct mechanical interaction with the environment, while the dorsal scales provide optical camouflage and thermoregulation. Recent work has demonstrated that compared to dorsal scales, ventral scales provide improved lubrication and wear protection. While biomechanic adaption of snake motion is of growing interest in the fields of material science and robotics, the mechanism for how ventral scales influence the friction between the snake and substrate, at the molecular level, is unknown. In this study, we characterize the outermost surface of snake scales using sum frequency generation (SFG) spectra and near-edge X-ray absorption fine structure (NEXAFS) images collected from recently shed California kingsnake (Lampropeltis californiae) epidermis. SFG’s nonlinear optical selection rules provide information about the outermost surface of materials; NEXAFS takes advantage of the shallow escape depth of the electrons to probe the molecular structure of surfaces. Our analysis of the data revealed the existence of a previously unknown lipid coating on both the ventral and dorsal scales. Additionally, the molecular structure of this lipid coating closely aligns to the biological function: lipids on ventral scales form a highly ordered layer which provides both lubrication and wear protection at the snake’s ventral surface.

Snakes move around by slithering—as their bodies undulate against a surface below their bellies, friction is applied that pushes the snake forward, but the molecular mechanism by which this occurs has never been fully understood. To learn more, the researchers obtained samples of the shedded skins of several California kingsnakes and studied them using sum frequency generation spectra and near-edge X-ray absorption fine structure imagery, which essentially involved firing lasers at the skin and then measuring how the light was reflected and scattered.The scanning revealed an extremely thin lipid layer, just nanometers thick, coating the scales that covered both the top and bottom parts of the snake, though there were differences between the lipid layer on the two body parts. The lipids on the belly were made of ordered pairs that provide a very slick surface, one that also offered, the researchers believe, some degree of protection to the scales—sliding across surfaces would otherwise cause the scales to wear away. A lipid outer layer would help explain why snakes are able to slither so effortlessly across a multitude of surfaces, the team notes.The reason that the lipid coating has not been noticed before by people handling the non-venomous snake, is because the lipid does not come off, it adheres to the snake body, providing a constant slick surface. The researchers suggest that because the kind of snake they studied was common, they believe the lipid coating likely exists on the scales of other snakes as well, though it likely comes in different forms suited to the environment in which the snake lives. They also believe their findings might help researchers working to make robots that simulate snakes, or those looking to create next generation paints or lubricants.

Kolkata: After the assurance of the Chief Minister through an audio message that the state government has decided to increase the salary of para teachers across the state, state Education minister Partha Chatterjee on Monday announces doubling of salary.Chatterjee while addressing the state convention of para teachers at Netaji Indoor stadium said: ” The salary of para teachers at the primary level has been increased from Rs 5954 to Rs 10,000 and at the Higher Secondary level, it has been enhanced from Rs 8,186 to Rs 13,000. It will be effective from March 2018.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedPresently, there are 46,000 para teachers across the state. The Education minister also announced a number of facilities for the para teachers. He informed that the reservation for the para teachers will be raised from 10 percent to 30 percent.Referring to the demands of allowing the para teachers to be a part of an institution’s managing committee and share the staff room along with regular teachers, the minister said: “We are aware of the problems that you face. We will sit and discuss about the matter,” Chatterjee maintained. He also sounded a word of caution to the para teachers and said the latter should not approach the court at the drop of a hat. “Problems are hardly sorted out in courts. If you have problem, it can be solved at the discussion table,” he added.The minister also assured that the para teachers will be able to work till the age of 60 and then will get retirement benefit of Rs 1 lakh. “We will also try our best to make them permanent,” he said. It may be mentioned that Banerjee in March had announced that the salary of the para teachers will be enhanced and so it has been made effective from March 2018.
