Kuchotsera Mtengo Bundor Din F4 Flanged 4 Inch Gate Valve Kupanga Ndi s Ductile Iron Sluice Vavu Yokhala Ndi Mpando Wokhazikika

Kanema wakuseri kwazithunzi uyu akuwonetsa chida chokhazikitsidwa ndi Matt Staymates, chomwe amagwiritsa ntchito kuwonetsa momwe masks angaletse kufalikira kwa COVID-19. News Report-Washington, Novembala 10, 2020-Mukawona wina akungoyendayenda m'sitolo kapena kwina kulikonse, atavala chigoba chokhala ndi valavu, ndikufuna kudziwa momwe kulili kotetezeka kwa inu, ndiye kuti muyenera kusamala. Matthew Staymates, injiniya wamakina komanso woyendetsa madzimadzi ku National Institute of Standards and Technology, akuphunzira mitundu yosiyanasiyana ya chigoba kuti adziwe chomwe chingachepetse kufala kwa matenda. Mu "Fluid Physics" yolembedwa ndi AIP Publishing, adafotokoza za kuwunika koyambira kwa masks a N95 okhala kapena opanda valavu yotulutsa mpweya. Kuti izi zitheke, adapanga mavidiyo odabwitsa kuchokera ku Schlieren imaging, njira yowonera kutuluka kwamadzimadzi ndi kuwala komwe kumabalalika kutali ndi chinthu. Valavu yotulutsa mpweya pa chigoba cha N95 idapangidwa kuti ipititse patsogolo chitonthozo cha ogwiritsa ntchito pochepetsa kukana kusefa panthawi yopuma. Staymates adati: "Mukatulutsa mpweya, chotchinga chaching'ono chimatsegulidwa, kotero kuti mpweya umatulutsa osasefa ndi zinthu za chigoba." "Ndikhoza kusonyeza mfundo yogwira ntchito ya valavu yotulutsa mpweya, ndikuyiyerekeza ndi valavu yotereyi. N95 inafanizidwa." Staymates adati kafukufuku wake akuwonetsa kuti masks a N95 okhala ndi ma valve otulutsa mpweya sali oyenera kusefa m'malovu opumira kuchokera kwa anthu. Anati: "Zomwe tikudziwa pano ndikuti gawo la COVID-19 limafalikira ndi madontho opumira, kotero panthawi ya mliriwu, N95 yokhala ndi valavu sithandiza kuwongolera magwero." Adapeza kuti chigoba cha N95 chopanda valavu chimatha kuletsa madontho ambiri amadzimadzi kuti asalowe muzinthu za chigoba. Staymates wakhazikitsa labotale yokongola yanyengo yonse pamalo ake opangira matabwa kuti ayese mitundu yosiyanasiyana ya masks ndi zida. Anapanga makina opangira mpweya kuti atsanzire momwe anthu enieni amatulutsira mpweya, ndipo adapanga makina opangira mpweya kuti athe kuyeza momwe amapumira. Anagwiritsa ntchito detayi ngati muyeso wa makina opangira mpweya. Staymates anati: "Ndinapanganso ndikumanga jenereta ya chifunga mkati mwa mutu wa mannequin. Jenereta ya chifunga imapereka madontho omwe ali ofanana kwambiri ndi omwe amwazikana ndi anthu." Exhale, ndi jenereta ya nkhungu imapangitsa kuwoneka ngati ikungosuta ndudu." Ananenanso kuti kugwiritsa ntchito kujambula kwa schlieren ndi matekinoloje ena owonera "kupitilira kutithandiza kumvetsetsa momwe masks ndi masks amaso amathandizira pakufalikira. za matendawa." "Ndikukhulupirira kuti ntchitoyi ithandiza kuti omvera adziwe Pogwirizana ndi mliri wapadziko lonse lapansi, mavavu okhala ndi masks sangathandize." Matthew Staymates analemba kuti "Kuwona koyenda pogwiritsa ntchito kujambula kwa schlieren ndi kubalalika kopepuka. Zopumira za N95 zokhala ndi valavu yotulutsa mpweya komanso zopanda mpweya". Zidzawoneka mu "Physics of Fluids" pa Novembara 10, 2020 (DOI: 10.1063/ 5.0031996). Tsikulo likatha, mutha kupita ku https://aip.scitation.org/doi/ 10.1063/5.0031996 Fluid Physics yaperekedwa ku zofalitsa zamalingaliro oyambilira, zowerengera ndi zoyeserera zagasi, zamadzimadzi komanso zovuta zamadzimadzi Onani https://aip.scitation.org/journal/phf. 00 am Eastern Time pa Novembara 12, 2020, PassPass ya atolankhani ikufunika kuti apeze nkhaniyi. NewswisePressPass imathandiza atolankhani otsimikizika kuti azitha kupeza nkhani zoletsedwa. Chonde lowani kuti mumalize kugwiritsa ntchito presspass. Ngati simunalembetse, chonde lembani. Mukalemba fomu yolembetsa, chonde tsimikizirani kuti ndinu mtolankhani musanalowe fomu yofunsira atolankhani. Kafukufuku wopangidwa ndi UCLA Field School of Public Health adapeza kuti ngakhale chigoba chosavuta cha nsalu chimatha kuchepetsa kufalikira kwa madontho opumira a COVID-19 ndi 77%. Mpaka nthawi yoletsa kutha pa Novembara 12, 2020 Eastern Standard Time, PassPass ya mtolankhani ikuyenera kupeza nkhaniyi. Chonde lowani kuti mumalize kugwiritsa ntchito presspass. Ngati simunalembetse, chonde lembani. Mukalemba fomu yolembetsa, chonde tsimikizirani kuti ndinu mtolankhani musanalowe fomu yofunsira atolankhani. Zotsatira zikuwonetsa kuti kuyezetsa kozama ndikofunikira kuti muchepetse kufalikira kwa COVID-19 mgulu lomwe lakhazikitsidwa Patatha miyezi iwiri muchipatala chimodzi mwa 38 ku Michigan, zotsatira za odwala a COVID-19 ndikuphatikizira kufa kwakukulu, kuchira, kupitilirabe thupi komanso malingaliro. mavuto azaumoyo, ntchito za tsiku ndi tsiku, mavuto antchito ndi azachuma. Theka la katemera amawonongeka chaka chilichonse chifukwa sasungidwa ozizira. Michigan Institute of Technology ndi UMass Amherst akatswiri opanga mankhwala apeza njira yokhazikitsira kachilomboka pakatemera wokhala ndi mapuloteni m'malo mwa kutentha. Anthu omwe achira ku coronavirus amatha kupanga ma antibodies olimbana ndi SARS-CoV-2, omwe amatha kusinthika pakadutsa miyezi ingapo atadwala. Ma antibodies awa amatha kusinthika potengera ma antigen otsalira omwe amabisika m'matumbo. Ofufuza ku Karolinska Institute ku Sweden adafufuza maphunziro onse a COVID-19 omwe adatulutsidwa koyambirira kwa mliri. Kafukufuku watsopano wochokera ku Notre Dame adawunika umunthu wokangalika kwa nthawi yoyamba pothana ndi vuto (mwachitsanzo, kuchipatala ku Wuhan, China, pachimake cha mliri wa coronavirus, koyambirira kwa mliri wa COVID-19). Newswise imapatsa atolankhani mwayi wopeza nkhani zaposachedwa komanso imapereka nsanja kwa mayunivesite, mabungwe ndi atolankhani kuti afalitse nkhani zazikulu kwa omvera awo.
