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 ...
HERVs comprise a significant part of the human genome, with approximately 98,000 ERV elements and fragments making up 5–8%. [1] According to a study published in 2005, no HERVs capable of replication had been identified; all appeared to be defective, containing major deletions or nonsense mutations (not true for HERV-K).

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.
Human endogenous retrovirus K (HERV-K) or Human teratocarcinoma-derived virus (HDTV) is a family of human endogenous retroviruses associated with malignant tumors of the testes.
LTR retrotransposons have direct long terminal repeats that range from ~100 bp to over 5 kb in size. LTR retrotransposons are further sub-classified into the Ty1-copia-like (Pseudoviridae), Ty3-like (Metaviridae, formally referred to as Gypsy-like, a name that is being considered for retirement [4]), and BEL-Pao-like (Belpaoviridae) groups based on both their degree of sequence similarity and ...
