St. Bernard’s experience earns them second win over McKinleyville this season

first_imgEureka >> In a game that mirrored their contest earlier in the season, experience once again paid dividends for the St. Bernard’s Crusaders in their second meeting against the McKinleyville Panthers.Once again the Crusaders were up by double digits in the first half, only to see the lead dwindle as Mack mounted a comeback in the final quarter. But the poise and leadership that comes with winning back-to-back NorCal titles proved too be the difference as the Crusaders downed Mack, 61-51, on …last_img read more

Researchers Claim to Develop a Concrete Alternative

first_imgSand for Construction Is VanishingThe World Is Facing a Sand CrisisReinventing ConcreteCarbon Emissions By the Construction Industry The inventors said Finite is non-toxic and can be left to decompose, or reused in a new product.“We could use the material to make pavilions, then after three months when the event ends it can be deconstructed safely,” said Carolyn Tam, one of the four developers.There’s no word from the developers on when, or whether, Finite might be produced commercially or whether it has been used even experimentally in a structural application. So far, the startup has a website and some intriguing ideas.“It will take more than just our project or one material, but we’re really looking forward to is a future where the built environment isn’t this thing where you keep it there forever or landfill it or down-cycle it, but something that uses nature and is continuously reusable,” Maccario told Dezeen. “As soon as you have new materials you have new opportunities.”Finite, of course, isn’t alone in looking for new production methods and materials that would lower the carbon impact of cement. Alex Wilson, for example, described one of them in an article about a company called Blue Planet posted at GBA in 2014 (see “Reinventing Concrete” in the Related Articles sidebar above.). Another effort was described in a post at Ensia in 2016. RELATED ARTICLES Researchers in the U.K. claim to have found a way to use desert sand in a composite construction material that’s just as strong as concrete but has only half of its carbon footprint.Four post-graduate students from Imperial College London developed a material they’re calling Finite that could help address a global shortage of construction-grade sand used as fine aggregate in concrete, the publication Dezeen reported.Billions of cubic yards of concrete are produced each year. In addition to straining supplies of construction-grade sand, concrete also requires a lot of cement, which is used as the binder. The production of cement is responsible for an estimated 5% of global carbon dioxide emissions.There’s plenty of desert sand available, but because it has been smoothed so effectively by the wind it hasn’t been considered useful for construction. The rapid depletion of high-quality sand is also likely to affect glassmakers, according to a symposium last fall, so a building material made from an abundant type of sand could prove to be a big deal.“Sand is the most consumed resource on earth after fresh water,” the Dutch design studio Atelier NL told Dezeen last year. “Yet sand is being excavated at a rate faster than it can renew itself.” Finite’s binders are unknownThe researchers didn’t say much about what goes into Finite, other than desert sand. Dezeen reported the binders used in the new material were a “guarded secret.” Matteo Maccario, one of the four students who developed Finite, said the team’s “worst-case estimate” is the blend would have less than half the C02 footprint of concrete.last_img read more

Dope: State drug controller of Punjab suspended

first_imgThe Punjab government on Thursday suspended the state drug controller with immediate effect in the wake of reports of availability of banned drugs in certain shops outside National Institute of Sports at Patiala.”The Punjab Health Department suspended Bhag Singh, State Drug Controller with immediate effect,” a spokesman said in Chandigarh.”Bhag Singh has been suspended for negligence of duties,” he added.Noting that during the period of suspension, he would be required to report at the Punjab Health System Corporation SAS Nagar Mohali headquarters and will not be allowed to leave without a prior permission.Meanwhile, the health department on Thursday began cancellation of licenses of chemist shops for selling banned steroids without prescription to the players receiving training in National Institute of Sports.On the instructions of Punjab Health Minister Satpal Gosian, the health department raided shops in the vicinity of NIS Patiala and three shops were found selling banned steroids and records of seven shops were found not in order.Ten shops were issued show cause notice by the department.- With PTI inputslast_img read more

A public celebration taking place over the course of “a couple of weeks” is scheduled for next month, according to the zoo.Kathy Hawk, lead mammal keeper joined Good Morning San Diego to share stories about working closely with each panda.The pandas’ departure marks the last pandas the zoo has on loan from the Chinese government. Zoo officials say that panda conservation efforts will continue, though in exactly what form was uncertain.
