Hauv colloid chemistry, flocculation hais txog cov txheej txheem los ntawm qhov zoo particulates tau tshwm sim los ua ke ua ke rau hauv floc. Cov floc tuaj yeem ntab mus rau sab saum toj ntawm cov kua (creaming), khom rau hauv qab ntawm cov kua (sedimentation), lossis npaj tau yooj yim lim los ntawm cov kua.
Hauv qhov no, flocculation hauv txheej txheem kho dej yog dab tsi?
Flocculation : A txheej txheem nyob qhov twg colloids tawm ntawm kev raug ncua hauv daim ntawv ntawm floc ua , xwm yeem los yog vim qhov ntxiv ntawm tus neeg hais qhia meej. Nws yog siv hauv daim ntawv thov zoo li dej huv , dej phwj tuaj kho , cheese tsim thiab brewing, piv txwv.
Ib sab saum toj no, txheej txheem kev tso quav yog dab tsi? Kev tso dej yog txheej txheem ntawm kev tso cov khoom hauv kev ncua hauv dej kom daws tawm ntawm qhov raug ncua raws li qhov nqus ntawm qhov nqus. Cov hais tawm uas tshem tawm los ntawm qhov raug tshem tawm ua cov quav, thiab hauv kev kho dej yog hu ua sludge.
Tib neeg tseem nug, qhov flocculation txhais li cas?
Cov txheej txheem uas ib tus neeg ntawm cov av nplaum sib sau ua ke rau hauv cov clotlike lossis ua kom cov dej me me. Flocculation tshwm sim los ntawm tshuaj lom neeg cov tshuaj tiv thaiv nruab nrab ntawm cov av nplaum thiab lwm yam khoom, feem ntau yog dej ntsev.
Kev siv flocculation yog dab tsi?
Flocculants , los yog flocculating cov neeg sawv cev (tseem hu ua cov neeg sawv cev pab pawg), yog cov tshuaj uas txhawb nqa flocculation los ntawm kev ua colloids thiab lwm yam kev tshem tawm hauv cov kua kom sib sau ua ke, tsim ua floc. Flocculants tau siv hauv cov txheej txheem kho dej txhawm rau txhim kho kev tso dej los yog lim dej ntawm cov khoom me me.

Dab tsi yog cov txheej txheem txheej txheem ntawm cov pob txha ua los ntawm?
Cov txheej txheem sab nraud, uas yog ua los ntawm cov organic matrix (30%) muaj cov proteoglycans (tab sis tsawg dua pob txha mos), glycosaminoglycans, glycoproteins, osteonectin (thauj cov pob txha pob txha mus rau collagen) thiab osteocalcin (calcium khi protein)
Lub luag haujlwm ntawm cov txheej txheem mastoid thiab txheej txheem styloid yog dab tsi?
Cov txheej txheem styloid nyob rau sab xub ntiag thiab nruab nrab rau cov txheej txheem mastoid, thiab nyob nruab nrab ntawm lawv yog stylomastoid foramen. Cov foramen no tso cai rau cov leeg nqaij ntawm lub ntsej muag lub ntsej muag tawm ntawm pob txha taub hau thiab mus rau sab hauv txhawb cov leeg ntawm lub ntsej muag
Cov txheej txheem ntawm Seldinger txheej txheem yog dab tsi?
Cov txheej txheem ntawm Seldinger Cov Txheej Txheem Kev Txhaj Tshuaj. Ntxuav thiab npaj qhov chaw xav tau. Insertion ntawm Guidewire. Tshem tawm koob. Qhov chaw txhaj tshuaj tau nthuav dav los ntawm kev siv cov hniav lossis cov zom zaws. Catheter tau muab tso rau. Qhov tso zaum kawg - rub daim ntawv qhia tawm
Puas yog CPT code hais txog cov txheej txheem cais ib feem ntawm cov txheej txheem?
Tus lej CPT hais txog tus txheej txheem cais yog txheej txheem uas tau tshaj tawm yog tias nws yog qhov kev pabcuam nkaus xwb. Yog tias nws ua tiav tib lub sijhawm nrog lwm cov txheej txheem (cov lis dej num yog rau cov kev pabcuam uas tau muab ua ke), cov txheej txheem no yuav tsis raug tshaj tawm
Cov kauj ruam hauv cov txheej txheem txheej txheem txheej txheem mob yog dab tsi?
Cov ntsiab lus hauv cov txheej txheem no (8) ua kom cov vascular endothelium. vasodilation. ua npaws ntau lawm. tsiv teb tsaws ntawm cov kab mob tiv thaiv kab mob hlwb mus rau thaj chaw. ua kom thiab cytokine tso tawm los ntawm neutrophils. phagocytosis thiab cov hau kev ntawm kev puas tsuaj. tus mob theem teb. clotting cascade
