water news - Drought-plagued California wants residents to drink recycled wastewater


Arrowhead. Poland Spring. Fiji. SmartWater. At the end of the day, it's all just the bottled product of what happens when two hydrogen molecules bond with an oxygen molecule, mixed with a few minerals here and there — and a movement in drought-plagued California is hoping water-drinkers can recognize that.
A New York Times report this morning spotlighted a specialized plant in Orange County where wastewater is processed through "several stages of purification that left it cleaner than anything that flows out of a faucet or comes in a brand-name bottle." In fact, the water is literally "stripped down to the H, 2, and O," the general manager of the county's water district explained, and the purification process removes the flavor-adding minerals found in most water supplies.
So the water is truly clean and environmentally friendly. Great! But while recycled water has been used successfully for things like irrigation in the past, turning it into a viable potable option is predicated upon people accepting that the water they're drinking was previously used for something else. Of course, this isn't actually a big deal — "everyone who lives downstream on a river is drinking recycled water," noted a water expert to the Times — but it does require Californians to get over the "yuck" factor. And despite the extensive science that goes into cleansing recycled water down to its molecular construction, in a recent study, 13 percent of adults said they would point-blank refuse to try it. Similar efforts in the past to jumpstart the recycled water trend in the state have failed.
Still, the movement is optimistic, in part because California's situation is so dire. "A small minority of people are very offended by this," said the study's co-author, Paul Rozin, but "under crisis, people accept things that they wouldn't accept otherwise."

Histoire de la Fin de la Croissance - Elle rêve de devenir Miss Belgique, son destin bascule


Âgée de 21 ans, belle comme un coeur, Mila Rasule a vu sa vie basculer et son rêve s'effondrer: celui de revêtir un jour la couronne de Miss Belgique. Quelques jours seulement après avoir appris qu'elle était reprise pour les présélections de Miss Flandre-Occidentale, la jeune femme a reçu l'ordre de quitter le territoire. Il y a huit ans, elle avait fui l'Afghanistan avec sa famille pour notre pays.

Depuis 2008, Mila vit à Ostende avec ses parents et sa sœur (18 ans). À Kaboul, sa famille avait été prise pour cible par le régime taliban pour des raisons religieuses. Son père est un Afghan de confession musulmane. Sa maman, elle, appartient à l'Eglise orthodoxe russe.

TICE, Web 2.0, logiciels libres - La course aux nombres – Un jeu qui enseigne l’arithmétique et combat la dyscalculie


C'est un logiciel de jeu amusant qui vous fait jongler avec les nombres, et enseigne les concepts fondamentaux de l’arithmétique. Le jeu a été imaginé par l’Unité INSERM-CEA de Neuroimagerie Cognitive, un centre de recherche de pointe en cognition mathématique.


Alain MICHEL's insight:

Un jeu (à télécharger) créé par l'équipe de recherche de l'INSERM-CEA.
La Course aux Nombres est destinée à l'origine aux enfants de 4 à 8 ans. Les enfants de maternelle y découvriront les concepts de base des nombres et de l’arithmétique. Ceux de primaire, qui connaissent déjà les nombres, apprendront à calculer de plus en plus vite.
Les concepts abordés sont :

  • Présentation des nombres – ensembles concrets, chiffres ou mots
  • Comptage - entraînement avec les nombres 1 à 40
  • Calculs élémentaires - additions et soustractions

Ce jeu est à rapprocher de "L'attrape-nombres" : http://sco.lt/5KFqZV
