Make-up air is designed to “make up” the air in your interior space that has been removed due to process exhaust fans. This type of HVAC solution pulls in fresh, tempered air from outside your building to replace existing air that cannot be recirculated. ...
The troposphere, the bottommost layer of Earth’s atmosphere, is the densest of the five atmospheric layers and extends from ground level up to about 10 kilometers in altitude. This is the layer where humans live and breathe, as it contains the air we depend on for survival. The tropospher...
Differing fromtopology optimization, generative design accelerates and enriches standard engineering processes. It boosts innovation, speeds up the development cycle, and promotes sustainable material use. By automating the generation of design options, engineers can focus on optimization and customization, im...
Any process that contains a flow of events, from air temperatures in a crowded room to the manufacture of aninjection molded plasticpart, can be simulated and tested visually. Simulations can be used to optimize a design, test a theory, train or improve safety, and even entertain. If you’...
A mask’s seal is arguably the most important element of an effective air quality mask. Lastly, a tight fit is also critical. Adjustable, comfortable straps help make the seal around your nose and chin airtight, providing another layer of protection against leakage while also helping prevent pai...

PFAS stands for perfluoroalkyl or polyfluoroalkyl substances, a group of chemicals that have properties that allow them to repel water, dirt, and oil. You may know them by an older term “PFCs,” or perfluorochemicals. Manufacturers use PFAS to make everyday household products, as well as th...
including impurities and stabilizing additives. This is important because impurities and stabilizing additives have their own classifications and contribute to the overall classification of the chemical substance. To begin with, all substances should have the following listed in Section 3: chemical name, ...
Due to its molecular stability, its exceptional resistance to UV radiation, and its non-reactivity in the presence of corrosive environmental substances such as water, acids, and ozone, the sheets that make up a roof’s field membrane can remain functional for over 50 years. ...
They were, the scientists guessed, using the insects to medicate. "What we think Is that maybe they're mixing it with their saliva(唾液)and pressing something out of the insect", said Simone Pika, from the University of Osnabruck, in Germany. There are some substances that might have anti...
