suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولAutocrine regulation of milk secretion by a protein in milk.
Frequency or completeness of milk removal from the lactating mammary gland regulates the rate of milk secretion by a mechanism which is local, chemical and inhibitory in nature. Screening of goat's milk proteins in rabbit mammary explant cultures identified a single whey protein of M(r) 7600 able to inhibit synthesis of milk constituents. The active whey protein, which we term FIL (Feedback inh...
متن کاملSuppression by perchlorate of technetium-99m and iodine-123 secretion in milk of lactating goats.
Lactating goats were infused with either technetium-99m (99mTc) or iodine-123 (123I) together with chlorine-36 (36Cl) through an indwelling catheter previously placed in an external pudic mammary artery. The radioisotope infusions were repeated together with 100 mg of sodium perchlorate. There was a rapid transfer of 99mTc and 123I into milk, reaching a peak concentration 30 min after a 15-min ...
متن کاملIs activation of the granulocyte by concanavalin-A a reversible process?
The stimulation of granulocyte O2- production by concanavalin-A can be reversed with alpha-methylmannoside. Such cells can be reactivated to generate O2- by adding phorbol myristate acetate or N-formyl-methionyl-leucyl-phenylalanine. Opsonized zymosan, however, is not an effective stimulant to these cells. alpha-Methylmannoside prevents, but does not reverse, depolarization of granulocytes by c...
متن کاملSuppression of myoblast fusion by concanavalin A: possible involvement of membrane fluidity.
Experimental evidence is presented which is consistent with the involvement of membrane fluidity during myoblast fusion. Treatment of pretrypsinized myoblasts with tetrameric Con A, but not with the dimeric succinyl derivate, inhibits fusion. Inhibition is reversed by treatment with alpha-methyl-D-mannoside or subsequent trypsinization. No inhibition is observed when the lectin is incubated wit...
