Economic effects of echinococcosis.
Torgerson PR. Torgerson PR. Acta Trop. 2003 Feb;85(2):113-8. doi: 10.1016/s0001-706x(02)00228-0. Acta Trop. 2003. PMID: 12606088 Review.
The death of these individuals results in the loss of the potential lifetime's economic output of these individuals. With alveolar echinococcosis the mortality rate is much higher and such consequences more severe. ...The total cost of the disease is the sum of the …

Power, muscular work, and external forces in cycling.
de Groot G, Welbergen E, Clijsen L, Clarijs J, Cabri J, Antonis J. de Groot G, et al. Ergonomics. 1994 Jan;37(1):31-42. doi: 10.1080/00140139408963620. Ergonomics. 1994. PMID: 8112280 Review.
During locomotion an imaginary flow of energy takes place from the metabolism to the environment, with some efficiency. The 'useful' mechanical muscle power output might be used to perform movements and to do work against the environment. The external power is defin …
