Ua haujlwm tau tshaj tawm hauv Joy Joy Journat of Arence archaeological Science: Tshaj Tawm. "Medianskie Geese" yog qhov chaw tshwm sim ntawm lub qhov ntxa ntawm tus tub huabtais Iyiv, uas yog hnub no nyob hauv Cairo Museum. Cov duab ntawm cov noog ntawm lub plaster tau pom los ntawm cov neeg Iyiv cov neeg Iyiv ntawm Auguste Mariet thiab Luigi Vassaly rov qab xyoo 1871. Lub feature ntawm daim duab tsis yog tsuas yog nyob rau hauv nws cov kev nthuav dav, tab sis kuj nyob rau hauv kev txawv thev naus laus zis, uas yog cov uas tsis muaj kev hloov pauv rau cov Iyi tebchaws.
Geese piav qhia txog qhov tseeb: tus kws kos duab siv xim ntuj. Lub hnub nyoog ntawm frescoes - kwv yees li 4,400 xyoo. Ua ntej rau qhov no, nws tau ntseeg tias daim duab qhia ntau hom noog: gees-gualis), anser alsernik (anser alsal) thiab lub teb chaws liab lub koob yees duab (Branta Reficollis).
Txawm li cas los xij, cov ntaub ntawv no tsis muaj tseeb: tsis muaj ntawm cov noog no, qhov tseeb, tsis tuaj yeem ntaus nqi rau ib qho lossis lwm tus. Ntxiv mus, lwm cov tsiaj nrog tib lub frescoes - dev, nyuj, cov khoom noj dawb yog qhov tseeb, vim tias lawv tau xwm txheej nyob rau hauv qhov me me.
Tus kws tshawb fawb los ntawm lub tsev kawm ntawm cov chemistry thiab biomolecular science ntawm University of Queensland (Australia) yog ib qho ntawm cov geese yog hais txog tu noob, uas tseem dim ntawm cov kws tshawb nrhiav. Feem ntau cov kws tshaj lij pom zoo tias ob ntawm peb tug noog uas nws lub cev tig rau sab laug, - Belolaki geese.
Tab sis tus kheej ntawm lwm cov noog yog kev ua xyem xyav: nws tsis paub meej heev rau qhov uas tsis zoo li cas. Qhov no yog qhov tseem ceeb ntawm ob tug noog uas tau pleev xim rau hauv grey thiab liab thiab saib sab xis. Txhawm rau kom tsis txhob twv ntawm cov kas fes, Ramilio siv cov qauv sib piv 13 ntawm cov yam ntxwv pom rau txhua tus noog, uas yog hu ua "tus cwj pwm tobias".
"Qhov no yog ib txoj kev ua tau zoo heev rau kev txiav txim siab hom - kev ntsuas quantitating ntawm cov noog kom muaj txiaj ntsig," tus kws sau ntawv hais.
Tom qab tshuaj xyuas cov yam ntxwv rau sab nraud, tus kws tshawb fawb tuaj txog rau qhov kev txiav txim siab txawv txawv ntawm cov plaub, uas tau piav qhia hauv cov nplooj ntawv Iyiv thaum ub. Yog li ntawd, lawv tej zaum yog tus rau ntawm daim ntawv tu noob.
