TINY TURTLE INVESTIGATORS: THE CASE OF THE LARGE STRAWBERRY
GOOD MORNING EVERYONE
“HAVE YOU TRIED BALANCING ON IT”
“YES OF COURSE I TRIED BALANCING ON IT JENKINS THIS IS NOT MY FIRST DAY AS A TINY TURTLE INVESTIGATOR”
HEY GUYS THIS IS TOTALLY WHAT I’M DOING AT MY SCHOOL!!!!
These vegetated surfaces don’t just look pretty. They have other benefits as well, including cooling city blocks, reducing loud noises, and improving a building’s energy efficiency.What’s more, a recent modeling study shows that green walls can potentially reduce large amounts of air pollution in what’s called a “street canyon,” or the corridor between tall buildings.
For the study, Thomas Pugh, a biogeochemist at the Karlsruhe Institute of Technology in Germany, and his colleagues created a computer model of a green wall with generic vegetation in a Western European city. Then they recorded chemical reactions based on a variety of factors, such as wind speed and building placement.
The simulation revealed a clear pattern: A green wall in a street canyon trapped or absorbed large amounts of nitrogen dioxide and particulate matter—both pollutants harmful to people, said Pugh. Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.
That’s why the green-wall study is “putting forward an alternative solution that might allow [governments] to improve air quality in these problem hot spots,” he said.Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.That’s why the green-wall study is “putting forward an alternative solution that might allow [governments] to improve air quality in these problem hot spots,” he said…

UNC is one of many colleges where students are begging officials to reassess rape culture.
GO UNC! :)
For those of us who fall between the cracks, being “black,” being “white,” being “Chinese,” being “Latino,” is complicated. These essays, exemplary of the legion meanings of race and culture, are about inconstant categories and shifting skins. Skin color and place of birth aren’t accurate signifiers of identity. One and one don’t necessarily add up to who. Cultural and racial amalgams create a third, wholly indistinguishable category where origin and home are indeterminate…What name do you give to someone who is a quarter, and eighth, a half? What kind of measuring stick might give an accurate estimation? If our understanding of race and culture can ripen and evolve, then new and immeasurable measurements about the uniqueness of our identities become possible.

When my professors cancel class so we can study
yep. because we live in middle earth, you see.
