Cov tub ntxhais kawm yuav kawm tias cov khoom tuaj yeem raug cais raws li hadrons - baryons thiab mesons- thiab lepton, txhua tus nrog nws cov khoom tiv thaiv, thiab lawv yuav tsum paub tias kev cuam tshuam ntawm cov khoom no tuaj yeem ua tau. tau piav qhia txog kev hloov pauv ntawm lwm cov khoom hu ua vector bosons.
Dab tsi yog ob hom lus tseem ceeb?
Muaj ob yam ntawm qhov tseem ceeb: matter particles, qee qhov sib xyaw ua ke los tsim lub ntiaj teb txog peb, thiab quab yuam cov khoom - ib qho ntawm cov photon, yog lub luag haujlwm. rau electromagnetic tawg.
Dab tsi yog qhov particle thiab antiparticles?
Antiarticle, subatomic particle muaj tib qhov loj li ib qho ntawm cov khoom zoo tib yam tab sis cov hluav taws xob sib txawv thiab lub sijhawm sib nqus. Yog li, positron (positively charged electron) yog cov tshuaj tiv thaiv ntawm cov hluav taws xob tsis zoo.
Dab tsi yog cov ntsiab lus ntawm cov khoom?
Atom Composition
Cov khoom uas me dua lub atom hu ua subatomic particles. Peb lub ntsiab subatomic particles uas tsim ib lub atom yog protons, neutrons, thiab electrons. Qhov chaw ntawm lub atom hu ua lub nucleus.
Leptons thiab hadrons yog dab tsi?
Hadrons yog cov khoom uas xav tias muaj zog nuclear quab yuam, whereas leptons yog particles uas tsis. Cov proton, neutron, thiab pions yog piv txwv ntawm hadrons. Cov electron, positron, muons, thiab neutrinos yog cov piv txwv ntawm lepton, lub npe lub ntsiab lus qis. Lepton xav tias lub zog tsis muaj zog nuclear.

Dab tsi yog cov tshuaj tiv thaiv catalyzed los ntawm cov enzymes tseem ceeb gluconeogenic?
Plaub qhov tshwj xeeb ntawm gluconeogenesis yog pyruvate carboxylase, nyob hauv mitochondrialmatrix, phosphoenolpyruate (PEP) carboxykinase nyob rau hauv mitochondrial matrix thiab cytosol, fructose-1, 6-bisphosphatase nyob rau hauv cytosol thiab qabzib-6-phosphatase nyob rau hauv endoplasmic reticulum (ER) .
Dab tsi yog qhov sib txawv ntawm tus neeg tsis haum tshuaj thiab tus kws tshuaj tiv thaiv kab mob?
Tus kws tshuaj tiv thaiv kab mob kho cov teeb meem kev noj qab haus huv coj los ntawm kev tiv thaiv kab mob. Kuj tseem hu ua allergists, immunologists yog cov kws kho mob uas kuaj xyuas, kho, thiab ua haujlwm los tiv thaiv kev tiv thaiv kab mob .
Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Dab tsi yog cov tshuaj tiv thaiv thermite qhia nws qhov tseem ceeb?
Teb: Cov tshuaj tiv thaiv ntawm hlau (III) oxide (Fe203) thiab txhuas ua rau cov cua sov ntau. Nws yog hu ua thermit reaction. Qhov kev tshem tawm cov tshuaj tiv thaiv no yog siv los koom nrog kev tsheb ciav hlau lossis cov tshuab tawg. Lub tshav kub uas muab tawm hauv cov tshuaj tiv thaiv melts hlau tsim .
