Conceptually, we define abnormal net hiring as the difference between the actual change in a firm's labor force and the expected change based on fundamental economic factors. Our primary estimate of expected net hiring is based on model (4), which is a regression of the percentage change in ...
GT pneumatic actuator is driven by air source through piston in cylinder to drive gear rack and other components, and finally converts to output torque force to control valve opening and closing. It can be divided into two functional specifications: single-acting...

These exploit a pump or vacuum to force analytes present in the air to flow through a sampler [7]. The sampler can be a trap, such as a tube packed with a bed or multibed of sorbents, for example polyurethane foam (PUF), XAD resin, active carbon, a porous polymer, or graphitised...
Air pollution poses a persuasive threat to global health, demonstrating widespread detrimental effects on populations worldwide. Exposure to pollutants, notably particulate matter with a diameter of 2.5 µm (PM2.5), has been unequivocally linked to a s
