FRC is the sum of expiratory reserve volume (ERV) and residual volume (RV) [2] and measures approximately 3000 mL in a 70 kg, average-sized male. [1] [2] It cannot be estimated through spirometry, since it includes the residual volume.
Therefore, minimizing duct pressure drop by minimizing turbulence at elbows and transitions is of importance. Duct elbow radius is usually 1 1/2 to 2 times the duct size. The side slopes of transitions are typically 10 to 30 degrees. Note: the duct gas velocity is chosen to minimize duct dust dropout.
DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...
Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
Reactivation of it or anomalous expression of HML-2 in adult tissues has been associated with various types of cancer [7] [8] [9] and with neurodegenerative diseases such as amytrophic lateral sclerosis (ALS). [10] [5] Endogenous retrovirus K (HERV-K) is related to mammary tumor virus in mice. It exists in the human and cercopithecoid genomes ...
Syncytin-2 also known as endogenous retrovirus group FRD member 1 is a protein that in humans is encoded by the ERVFRD-1 gene. [5] This protein plays a key role in the implantation of human embryos in the womb. [6] This gene is conserved among all primates, with an estimated age of 45 million years. The receptor for this fusogenic env protein ...
