The vatsvakurudzi vanoti zvisaririra yezvinonhuhwira kunogona kubatsira Vezvemitemo kugadzirisa mhosva. Masayendisiti akawana kuti makemikari zvinoumba nokunhuhwira anogona kubva kune mumwe munhu kuburikidza zvipfeko, kunyange kana iriyo pfupi chaizvo. Next munhuwi uyu zvinosara nguo kwemazuva mashomanana, pasinei nokuti kunoderedza pamusoro nguva. Boka vaongorori vanoti basa ravo uchapupu-of-musimboti, zvichireva kuti midzimu inogona kushandiswa uchapupu.

chinyorwa kutsvakurudza

Vaongorori rakabudiswa basa ravo rendangariro "Science & Justice". Vanoti zvinonhuhwira kuongorora inogona inobatsira vanenge apo paiva pedyo chaiko vachionana, akadai kuburikidza panyaya dzepabonde.

Kunyange kune zvidzidzo zvakawanda mumunda forensic sayenzi - somuenzaniso, kuongorora fibers kana upfu vakasara pashure vachiridzira - saka kure ikoko pasina zveBhaibheri kutapurirana mweya.

Zvakabuda basa masayendisiti

Anonhuwira yakaitwa kubva dzakawanda dzakasiyana namakemikari zvinoriumba, izvo zvabatanidzwa kuva akasiyana kunhuwa. The vanotsvakurudza vakashanda pamwe rume munhuwi. Vakawana kuti zvimwe yenhengo izvi zviri nyore kubva mumwe chimedu donje.

Kana zvidimbu zviviri zvinhu vakamanikidzwa pamwechete miniti imwe, kune rimwe jira wechipiri 15 of 44 namakemikari zvinoriumba. Apo kuonana nguva yakanga yawedzera kusvika maminitsi 10 pazuva rimwe zvinyama yakapfuura kuti 18 zvinoriumba.

kunokosha zvakadini nguva

Masayendisiti uyewo kuongororwa sezvo nguva paupenyu chokufambisa pamusoro kugadzikana yeimwe.

Vakawana kuti kana pashure maminitsi 5 pashure rakachengetedzwa sprayed pamwe munhuwi, Svinai jira kune vamwe kwemaminitsi 10, ipapo ndichaenda 24 of 44 pefiyumu ingredients. Kana munhuwi vakanga sprayed 6:00 shure pane imwe zvinyama vaaisangana akatamisa 12 zvinoriumba, nepo vhiki pashure Uchiri unogona kuwana zvisaririra matanhatu kugadzikana zvinoriumba.

Dr. Ruth Morgan, mukuru mukuru Center kwemhosva, akati kuti masayendisiti nemhaka iyi experimental kudzidza aigona kuratidza kuti midzimu inogona kune dzimwe zvinyama, uye zvinokwanisika kuziva kana zvakaitika.

How kushandisa zvinonhuhwira recreate mhosva Chiitiko

Mune ramangwana zvingave mamiriro ezvinhu apo richava kuonana pakati vanhu vaviri, asi nzira iyi kunoita kuti tione kunyorerana mhando rakauya uye kwakati.

Zvisinei, masayendisiti vanoti kuti uchapupu hwakadaro anofanira unganidzwa nokukurumidza pashure zvaitika mhosva, sezvo kunonoka kunogona kukutadzisa richibatsira kwayo. Izvi zvinoreva kuti kushandisa zvisaririra yezvinonhuhwira haisi nguva dzose zvinoita nokuda mhosva kazhinji pakuzivikanwa mazuva mashomanana zvavakaita. Uyezve, hazvingaiti kuti vachanzwikwa kushandiswa chete munhuhwi kugadzirisa nyaya.

Midzimu Next havagoni kuva chete uchapupu mhosva. Masayendisiti tariro kuti ichi uchapupu richashandiswa vari kunzwisisa, pamwe DNA pachisara Somuenzaniso, kana zveminwe. Uye pachiimbwa nedzimwe nzira uchapupu zvichava kuvaka hunogutsa chaizvo mufananidzo.

Vanotsvakurudza vanoti zvakakosha kuita zvakawanda basa kuongorora kwakafanira yezvinonhuhwira kuti zvokutonga chaizvoizvo pazvinhu.
