Zd\u00e1 se, \u017ee se poda\u0159ilo naj\u00edt skute\u010dnou p\u0159\u00ed\u010dinu nehody kosmick\u00e9 lodi „Apollo 13<\/em>„\u2026<\/strong>
\nBadatel\u00e9 objevili v \u010dasopisu Discover Magazine<\/em> \u00fa\u017easn\u00fd v\u00fdzkum americk\u00fdch v\u011bdc\u016f, prov\u00e1d\u011bn\u00fd p\u0159ed odesl\u00e1n\u00edm astronaut\u016f na M\u011bs\u00edc.<\/p>\n

Uk\u00e1zalo se, \u017ee Doris H. Calloway<\/em> z University of California<\/em> a Edwin L. Murphy<\/em> z v\u00fdzkumn\u00e9 laborato\u0159e katedry pracovn\u00edk\u016f zem\u011bd\u011blstv\u00ed, porovnali stravu americk\u00fdch astronaut\u016f, a doporu\u010denou stravu jak v pr\u016fb\u011bhu vesm\u00edrn\u00fdch let\u016f, tak i b\u011bhem cesty na M\u011bs\u00edc.<\/p>\n

Jedna z prvn\u00edch prac\u00ed byla nazv\u00e1na „Vod\u00edk a metan ve st\u0159evech lid\u00ed, poj\u00eddaj\u00edc\u00edch kosmickou stravu.“ (Intestinal hydrogen and methane of men fed space diet). <\/em>(1)<\/p>\n

C\u00edlem studie bylo zjistit, kter\u00e1 dieta vyvol\u00e1v\u00e1 v\u011bt\u0161\u00ed nad\u00fdm\u00e1n\u00ed \u010dlen\u016f pos\u00e1dky. A v d\u016fsledku toho vy\u0161\u0161\u00ed produkci t\u011bchto plyn\u016f. To znamen\u00e1 – z astronaut\u016f do vnit\u0159n\u00edho prostoru kosmick\u00e9 lodi nebo do skafandru.<\/p>\n

Ameri\u010dt\u00ed v\u011bdci v\u00e1\u017en\u011b zkoumali proces, kter\u00fd se v akademick\u00fdch kruz\u00edch naz\u00fdv\u00e1 flatulence.<\/em> (1)<\/p>\n

Pro\u010d tento probl\u00e9m zaj\u00edmal v\u011bdce celkem t\u0159ikr\u00e1t b\u011bhem t\u0159\u00ed let \u2013 v letech 1968 a\u017e 1971? Ukazuje se, \u017ee NASA si byla v\u011bdoma toho, \u017ee \u0161\u00ed\u0159en\u00ed t\u011bchto plyn\u016f v kosmu nen\u00ed stejn\u00e9 jako na Zemi.<\/p>\n

V uzav\u0159en\u00e9m prostoru kosmick\u00e9 lodi nebo skafandru je flatulence<\/em> velmi nebezpe\u010dn\u00fd jev. A b\u011bhem let\u016f na M\u011bs\u00edc byla snaha sn\u00ed\u017eit riziko na minimum. Proto byly tyto v\u00fdzkumy br\u00e1ny velmi v\u00e1\u017en\u011b, byly vyvinuty odpov\u00eddaj\u00edc\u00ed metody pro posuzov\u00e1n\u00ed flatulence, byla vyd\u00e1na r\u016fzn\u00e1 doporu\u010den\u00ed.<\/p>\n

Nebezpe\u010d\u00ed flatulence<\/em> je z\u0159ejm\u00e9. Obsahuje a\u017e 47 procent vod\u00edku, 26 procent metanu a 23 procent kysl\u00edku. Stru\u010dn\u011b \u0159e\u010deno, v omezen\u00e9m a uzav\u0159en\u00e9m prostoru je to v\u00fdbu\u0161n\u00e1 sm\u011bs. Sta\u010d\u00ed mal\u00e1 jiskra …<\/p>\n

P\u0159\u00edm\u00fdm m\u011b\u0159en\u00edm Doris<\/em> a Edwin<\/em> zjistili, \u017ee strava \u201eS\u201c podporuje flatulenci, a naproti tomu dieta \u201eF\u201c, ji naopak potla\u010duje.<\/p>\n

M\u00e1te-li z\u00e1jem o \u010d\u00edsla, tedy z potravy \u201eS\u201c astronaut pr\u016fm\u011brn\u011b vyprodukuje 730 ml vod\u00edku a 383 ml metanu. Kde\u017eto p\u0159i strav\u011b \u201eF-80\u201c jen 222 ml oboj\u00edho.<\/p>\n

To ov\u0161em jen za norm\u00e1ln\u00edho atmosf\u00e9rick\u00e9ho tlaku, varuj\u00ed v\u011bdci. Ale pokud jde o let v omezen\u00e9m prostoru, tyto hodnoty jsou velmi nebezpe\u010dn\u00e9.<\/p>\n

Mimochodem, velmi podez\u0159el\u00e1 je nehoda na lodi „Apollo 13<\/em>“ v dubnu 1970. Tehdy explodovala kysl\u00edkov\u00e1 n\u00e1dr\u017e. \u0160lo z\u0159ejm\u011b o vliv flatulence.<\/em> Do\u0161lo k poru\u0161en\u00ed v\u00fd\u017eivov\u00fdch doporu\u010den\u00ed a k hav\u00e1rii do\u0161lo t\u0159et\u00ed den letu k M\u011bs\u00edci\u2026<\/p>\n
