Horraantii safka-19 faafa, waraaqda musqusha oo yaraaday dukaameeyeyaasha oo waxay u horseedeen kayd dagaal iyo dulsaar kordhaysa oo ka mid ah waxyaabaha kale ee lagu beddelo. Hadda, mashaakil la mid ah ayaa saameyn ku leh saynisyahanada sheybaarka: la tuuro, gaar ahaan talooyinka caagga ah, gaar ahaan talooyinka pipette, Sally Grara ayaa u soo sheegay in tilmaanta NPR.
Tilmaamaha Pipettewaa aalad muhiim u ah dhaqaajinta tiro cayiman oo dareeraha ah ee shaybaarka. Cilmi baarista iyo tijaabinta laxiriirta qafis-19 ayaa kicisay baahi weyn oo loogu talagalay balaastigga, laakiin sababaha sababihii balaastikada ayaa ka gudbaya meel u baahda. Waxyaabaha ka soo jeeda cimilo daran ilaa shaqaalaha yaraanta ayaa ku dhacday heerar badan oo silsilad sahaydu ay farageliyaan soo saarista sahayda sheybaarka aasaasiga ah.
Saynisyahannaduna waxay ku adag tahay mala-awaal waxa ay u ekaan karaan cilmi-baarista oo aan lahayn talooyinka Pipette.
"Fikradda ah in la sameeyo sayniska iyada oo aan la micneyn," ayuu yidhi maareeyaha sheybaarka ee Octrielle Bostwick toStat News'Kate Sheridan.
Tilmaamaha Pipettewaa sida caloosha turkey oo hoos udhacaya dhowr inji muddo dheer. Halkii ay ka isticmaali lahayd guluubka caagga ah dhamaadka ah oo la tuuro oo loo sii daayo si ay u nuugaan dareeraha, talooyinka pipette ku dheji micropipette-ka in saynisyahanku ka soo qaado cabir gaar ah oo dareere ah, badiyaa lagu cabiro microlicaters. Tilmaamaha Pipette waxay ku timaadaa cabirro kala duwan iyo qaabab shaqooyin kaladuwan, saynisyahannaduna sida caadiga ah waxay u isticmaalaan talo cusub muunad kasta si looga hortago faddaraynta.
Imtixaan kasta oo dovid-19 ah, saynisyahannadu waxay u isticmaalaan afar talooyin oo pipette ah, Gabe Howell, oo ka shaqeeya isu-qaybiyeyaasha shey ee San Diego, ayaa u sheegay NPR. Oo Mareykanku kaligiis wuxuu wataa malaayiin imtixaannadan maalin kasta, sidaa darteed xididdada sahayda balaastigga ah ee hadda jira ayaa dib ugu laabanaya goor hore ee masiibada.
"Ma aqaano wax shirkad ah oo leh wax soo saar kala badh ah oo laxiriira imtixaanka [199]] ee aan la kulmin si weyn u baahan in si buuxda u ba'an awooda waxsoosaarka ee meesha ku jiray," ayuu yidhi Kaiat Madaxweynaha Maareynta Saynada Saynada ee Qiyaasta ee QIAGG, oo ay ku taal Shawna Williams eeCilmi yaqaanejoornaal.
Saynisyahannada sameeya dhammaan noocyada cilmi baarista, oo ay kujiraan hiddo-wadaha, bioenginering, baaritaannada bayoolajiga ee dhallaanka ah iyo cudurada naadirka ah, waxay ku tiirsan yihiin talooyinka pipette ee shaqadooda. Laakiin sahayda yarida ayaa hoos u dhigtay xoogaa shaqo ah bilo, iyo waqtiga lagu qaatay raadraaca tirakoobka dhimista waqtigii loogu talagalay in baaritaan lagu sameeyo.
"Waqti badan oo aad u badan ayaad ku qaadataa inaad ku ogaato inaad gabi ahaanba ka gawrato tirakoobka sheybaarka," ayuu yidhi Jaamacadda California, San Diego Syntheratic-ka Syntheral Antny BerddtCilmi yaqaanejoornaal. "Maalin kasta oo kale ayaan si dhakhso leh u hubineynaa qolka suuqa, taasoo hubineysa inaan haysanno wax walba oo aan qorsheyno ugu yaraan lix ilaa sideed toddobaad ka hor."
Arinta silsiladda sahaydu waxay ka gudbeysaa baahida loo qabo baahida balaastigga ah ee raacay safka-19 safka ah. Marka duufaanta jiilaalka ee URI jiilaalka ee Febraayo, korantada ayaa ka dhacay wax soo saarka dhirta abuuraya polypropylene resin, sheyga ceeriin ee loogu talagalayTilmaamaha Pipette ee caagga ah, taas oo u horseedaysa in ay yaraato talooyinka, warbixinnadaStarin warar.
