An air quality monitor. Human exposure to aerosols has a variety of adverse health effects. [7] Building occupants complain of symptoms such as sensory irritation of the eyes, nose, or throat; neurotoxic or general health problems; skin irritation; nonspecific hypersensitivity reactions; infectious diseases; [8] and odor and taste sensations.

Double Take was a female pop duo consisting of Drew Garrett and Lauren Willey. [1] From San Luis Obispo, they are best known for their 2012 single "Hot Problems", which they released during high school. Upon its release, "Hot Problems" and its accompanying music video went viral and became an Internet meme. It garnered a decidedly poor ...
The therm (symbol, thm) is a non-SI unit of heat energy equal to 100,000 British thermal units (BTU), [1] and approximately 105 megajoules, 29.3 kilowatt-hours, 25,200 kilocalories and 25.2 thermies. One therm is the energy content of approximately 100 cubic feet (2.83 cubic metres) of natural gas at standard temperature and pressure .
A dramatic southward push of Arctic air into the eastern two-thirds of the country this week will result in bitterly cold conditions with temperatures trending 20-40 degrees Fahrenheit below ...
The downward-moving exterior is caused by colder air being displaced at the top of the thermal. The size and strength of thermals are influenced by the properties of the lower atmosphere (the troposphere). When the air is cold, bubbles of warm air are formed by the ground heating the air above it and can rise like a hot air balloon.
Normally, the Northern Hemisphere jet stream travels fast enough to keep the concentration of Arctic air known as the "polar vortex" stationary in the stratosphere over the North Pole. From late December to early January, a sudden stratospheric warming event was observed over the Arctic, which caused the "polar vortex" to weaken and split into ...
The overall cooling efficiency depends on how the air distribution system moves air through the equipment room, how the equipment moves air through the equipment frames, and how these airflows interact with one another. High heat-dissipation levels rely heavily on a seamless integration of equipment-cooling and room-cooling designs.
The relationship between pressure and leakage air flow rate is defined by the power law model between the airflow rate and the pressure difference across the ductwork envelope as follows: q L =C L ∆p n. where: q L is the volumetric leakage airflow rate expressed in L.s −1; C L is the air leakage coefficient expressed in L.s −1.Pa −n
