Kuda mizimu zingathandize kuthetsa milandu

Ofufuza amasonyeza kuti tayamba wa mafuta angathandize yazamalamulo mabungwe kuthetsa milandu. Asayansi apeza kuti zigawo mankhwala kununkhira akhoza inasamutsidwa kuchoka amapatsirana kudzera zovala, ngakhale kukhudzana ndi waufupi kwambiri. Kenako kununkhira adakali pa zovala kwa masiku angapo, ngakhale kuti amachepetsa pa nthawi. A gulu la ofufuza amanena kuti ntchito yawo ndi umboni wa mfundo zomwe zimasonyeza kuti mizimu angagwiritsidwe ntchito ngati umboni.

buku la kafukufuku

Ofufuzawa lofalitsidwa ntchito yawo mu magazini "Science & Justice". Iwo amanena kuti kusanthula mafutawo akhoza kukhala chida chothandiza milandu pamene panali pafupi thupi kukhudzana, monga mwa zachipongwe.

Kukuthandiza kafukufuku Simon Gergely ku University College London, anati: "Ife kuyembekezera kuti kusanthula kuda mafutawo mungathe yaikulu, anthu ambiri amagwiritsa ntchito. Ndipotu, pafupifupi 90% ya amayi ndi 60% ya anthu kuwagwiritsa ntchito nthawi zonse. "

Ngakhale pali maphunziro ambiri mu munda wa sayansi azamalamulo - mwachitsanzo, kusanthula ulusi kapena ufa zotsalira pambuyo yowotcha - mpaka pakhala palibe maphunziro pa kulanda mizimu.

The zotsatira za ntchito asayansi

Perfume amapangidwa zigawo zosiyanasiyana mankhwala, lomwe linali ndi fungo wapadera. Ofufuzawa ntchito ndi kununkhira wamphongo. Iwo anapeza kuti ena mwa zigawo zikuluzikulu zimenezi mosavuta inasamutsidwa kuchoka limodzi ndi mbali ina ya thonje.

Pamene zidutswa ziwiri za chuma amayengeramo pamodzi kwa miniti imodzi, anasamutsidwa ndi nsalu yachiwiri 15 44 zigawo mankhwala. Pamene kukhudzana nthawi kuchuluka kwa mphindi 10, pa minofu ena zinapita 18 zigawo zikuluzikulu.

N'chifukwa chiyani nthawi

Asayansi komanso kuunikira nthawi anakopa mayendedwe a kosakhazikika mankhwala.

Iwo aona kuti pambuyo Mphindi 5 pakatha sprayed ndi kununkhira Finyani nsalu ina kwa mphindi 10, ndiye adzapita 24 44 mafutawo zosakaniza. Ngati kununkhira anali sprayed 6:00 kumbuyo pa minofu ena anakumana anasamutsa 12 zigawo, pamene patapita mlungu umodzi mungathe akupezabe kuda zigawo zikuluzikulu asanu oyaka.

Dr. Ruth Morgan, mkulu wa Center kwa milandu, ananena kuti asayansi chifukwa cha kuphunzira izi experimental tikhoza kusonyeza kuti mizimu akhoza anasamutsa kwa minofu ina, ndipo n'zotheka kudziwa kwenikweni pamene izo zinachitika.

Kodi kugwiritsa ntchito mafuta onunkhiritsa recreate upandu powonekera

M'tsogolo mwina zina zidzakhala kukhudzana pakati pa anthu awiri, koma njira imeneyi zimathandiza inu kupeza mtundu wa kukhudzana zimene zachitika ndi pamene izo zinali.

Komabe, asayansi kuti umboni umenewu iyenera kusonkhanitsidwa mwamsanga pambuyo izo zinachitika kukhumudwa, kuyambira kuchedwa lingachepetse phindu lake. Izi zikutanthauza kuti kugwiritsa ntchito kuda mafuta sizingatheke, chifukwa cha milandu nthawi zambiri anadziwika masiku angapo pambuyo achita. Komanso, ndi chodziwikiratu kuti iwo kugwiritsidwa ntchito fungo kuthetsa choncho.

Kenako mizimu sangakhale umboni wokha ndi mlandu. Asayansi akukhulupirira kuti umboni limeneli lidzagwiritsidwa ntchito mu zovuta limodzi ndi kusanthula DNA, mwachitsanzo, kapena Fingerprints. Ndipo molumikizana ndi njira zina umboni kuti adzamange chithunzi wotsimikizika kwambiri.

Ochita kafukufuku amanena kuti m'pofunika kuti agwire ntchito kwambiri kuti aone ntchito bwino mafutawo kwa milandu zojambulidwa m'chombocho.
