On clear still nights when the heat island is pronounced, a small thermal low-pressure area forms over the city. Sometimes a light breeze—called a country breeze—blows from the countryside into the city. If there are major industrial areas along the outskirts, pollutants are carried into the...

"Through the study of glacier changes and glacier air pollutants, we can see the impact of global and regional human activities in the Qomolangm a area," Kong said.1. What do we know about the expedition team? A. They built the world's highest automatic weather station. B. They found...
The clear skies and stable meteorological conditions resulted in accumulation of pollutants in the boundary layer. At the same time, the mesoscale low-level-jet (LLJ) played an important role in transporting air masses from the polluted Mid-Atlantic areas to the Northeast. Local land-sea-breeze ...
The air quality has worsened in the Chinese capital since Wednesday, causing renewed discontent among residents. Without rainfall and wind to decrease pollutants, particulate matter(颗粒物质) has been accumulating in the air. Most monitoring stations measured PM 10(particulate matter smaller...
You’ve found one right here. They fight with other dogs. It was an opportune time for retail therapy. The case of the Klepcys Vertical Skeleton Tourbillon has a diameter of 44 mm, excluding the two crowns. The crown at 3 o’clock adjusts the time and winds the movement, while the ot...
everything you want. With the Dyson Purifier Humidity+Cool, it automatically senses, captures, and traps pollutants so you gain cleaner air with no hassle or requirement to do a thing. It’s able to detect and destroy formaldehyde as well as many other pollutants so you’re in safe ...
Furthermore, their high solubility in water and resistance to degradation in nature make them emerge as persistent pollutants in the aquatic environment [6]. Artificial sweeteners from the aquatic environment could easily come back to humans. Aside from the possibility of bioaccumulation by planktonic ...
Moreover, they found that if 0<p≤10<p≤1, the solution to (2) exists globally. In contrast, for 1<p<1+2n1<p<1+2n, the solution experiences blow-up in a finite time for any positive nontrivial initial data. Furthermore, if p≥1+2np≥1+2n, the solution also blows up in ...
Polybrominated biphenyls (PBBs) are a class of brominated flame retardants with 209 homologs. Hexabromobiphenyl (PBB-153) is the main component of PBB flame retardants and is listed in Annex A of the Stockholm Convention on Persistent Organic Pollutants (POPs) [1]. As an additive flame retardan...
