Reversible decrease in activity due to the interaction of P species with the protonic sites; External surface blockage; Decrease in the microporous volume; and even.
Even so, before the steaming treatment, the impregnation with phosphorus was said to produce several counterproductive effects [22]: Reversible decrease in activity due to the interaction of P species with the protonic sites; External surface blockage; Decrease in the microporous volume; and even De-alumination.
The model allows for such practical aspects of the problems under consideration as blockages, internal heat loads, external weather conditions, the presence of people, etc.
He can become impotent -- that chance is not as well quantified as it is with surgery and external beam radiation -- and might have problems with blockages in the urethra.
Large molecules therefore might cause more adverse blockage on large GAC particles (with small external surface) compared to small GAC particles (with larger external surface).
Studies on synthetic multifunctional pores with external and internal active sites for ligand gating and noncompetitive blockage are presented, with emphasis on the contribution of external ligands to the characteristics of pore.
An implanted subcutaneous infusion pump offers the benefit of a 3-fold lower incidence of treatment interruption and a 30-fold lower incidence of catheter blockage than when continuous infusion chemotherapy is given via an external infusion device.
The model incorporates both non-stationarity in the mean and in the variance, which are modelled as functions of external covariates such as radar imagery, distance to radar station and radar beam blockage.
A decrease in surface area/porosity can be attributed to pore blockage by P-species, aggregation of zeolite crystals by the action of external polyphosphate, or dealumination.
