Cell factorysearraí inchaite a úsáidtear go coitianta i réimsí na hoibre cógaisíochta, forbairt vacsaíní, agus antasubstaintí monachlónacha. Éilíonn cultúr na gceall timpeallacht ar leith, arb é steiriúlacht an bunriachtanas. Mar sin, conas a dhéanann monarcha ceall riachtanais steiriúlacht a bhaint amach?
Ciallaíonn steiriúlacht chultúr na gceall nach féidir le microorganisms eile a bheith ann i dtimpeallacht fáis, rud a chuirfidh isteach ar fhás agus atáirgeadh cealla. Chun ceanglais den sórt sin a chomhlíonadh, ní mór earraí inchaite cosúil le monarchana cille a bheith steiriúil freisin. Ar an gcéad dul síos, déanfar na hábhair inchaite seo a tháirgeadh sa cheardlann glan chun steiriúlacht na timpeallachta táirgthe a chinntiú. Ar an dara dul síos, tar éis an mhonarcha cille a tháirgeadh, beidh sé faoi réir cóireála steiriliú bhíoma leictreon chun freastal ar riachtanais sterility.
Electron beam marú baictéir bhitheolaíoch teicneolaíocht steiriliú a chuireann ionradaíocht béite i bhfeidhm ar steiriliú. Is modh é chun miocrorgánaigh a mharú le léas leictreoin ardluais le fuinneamh 3MeV-5MeV (milliún leictreon volta) a ghintear le luasaire leictreon. Feidhmíonn an léas leictreon go díreach ar DNA núicléas na cille, gearrann sé naisc mhóilíneacha DNA, nó imoibríonn sé go ceimiceach leis an uisce sa chill chun staid ghníomhach a fhoirmiú, agus gníomhaíonn sé ar na macramóilíní sa chill chun bac atáirgthe a chur faoi deara. Is féidir é a úsáid le haghaidh steiriliú táirgí indiúscartha leighis agus sláintíochta, bia, beatha peataí, bréagáin, etc.
Cé go bhfuil steiriúlacht an coinníoll bunúsach de chultúr na cille, sa phróiseas úsáid a bhaint as an cell mhonarcha, tá sé riachtanach freisin lean na nósanna imeachta forordaithe, ionas go mbainfear amach torthaí dea-chultúr cille.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
