Ukuthuthuka okusheshayo komkhakha wesayensi yezempilo kuqhubekile nokwandisa isidingo sezinto ezisetshenziswayo zesiko lamaseli. Phakathi kwazo, i-izimboni zamaseli yamaseli asezingeni eliphezulu ithandwa izinkampani eziningi zemithi nabakhiqizi bemithi yokugoma. Ukukhula kwamangqamuzana kudinga izimo ezithile, ngaphezu kwendawo eyinyumba, kudinga izinga lokushisa elifanelekile.
Ngokujwayelekile, izinga lokushisa elifanele lamangqamuzana ezilwane ezincelisayo kanye nezinyoni zezinyoni ukuze akhuliswe ku-invitro ngu-37-38°C. Izinga lokushisa le-ambient elingafanele lizothinta ukukhula kwamaseli. Ukubekezelelana kwamaseli ekushiseni okuphansi kunamandla kunokushisa okuphezulu. Emazingeni okushisa aphansi, umsebenzi we-metabolic kanye namandla e-mitotic amaseli kuyehla. Uma izinga lokushisa lingekho ngaphansi kuka-0 ° C, nakuba i-metabolism yeseli ithinteka, akukho monakalo; ku-25 kuya ku-35 °C, amaseli akhula ngesilinganiso esincane.
Izinga lokushisa eliphezulu alilungile kusiko lwamaseli. Uma amaseli ekhuliswe ku-39 ~ 40 ° C ihora elingu-1, azolimala ngezinga elithile, kodwa angase alulame, kodwa awakwazi ukubekezelela ukunyuka kwezinga lokushisa kuka-2 ° C amahora ambalwa. Ukuhlinzwa kubi kakhulu, futhi amaseli amaningi ayafa lapho izinga lokushisa lingaphezu kuka-43 °C. Ukushisa okuphezulu kubangela ukungasebenzi kwama-enzyme, ukucekelwa phansi kwe-lipidoid, ukucekelwa phansi kokuhlukaniswa kwenuzi, ukukhiqizwa kwe-coagulase, ukuhlangana kwamaseli, kanye nokuguqulwa kwamaprotheni. Ngakho-ke, izinga lokushisa eliphezulu kufanele ligwenywe lapho kulima amangqamuzana e-in vitro. Uma usebenzisa amafekthri amaseli ukwenza isiko lamangqamuzana, i-incubator ehlala njalo noma i-greenhouse isetshenziselwa ukuqinisekisa ukuthi amangqamuzana ahlala esezingeni lokushisa elifanele futhi agcina isimo esihle sokukhula.
Izinga lokushisa elifanele lingesinye sezimo eziyisisekelo zokutshala amaseli izimboni zamaseli. Ngaphezu kwalokho, imvelo eyinyumba, ingcindezi ye-osmotic, indawo yegesi kanye ne-pH iyadingeka. Noma yikuphi ukwehluleka ukuhlangabezana nendinganiso kuzothinta inqubo yesiko lamaseli.
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.
