Non-catalytic pyrolysis of brown macroalgae (Padina sp.) was studied in a batch reactor at temperature ranges 400–600 °C and 10–90 min reaction times on the product distribution conversion rate behavior. The highest pyro-oil pyro-gas yields were obtained 600 °C, which reached 67 wt% 27 wt%, respectively, when prolonged (30–90 min). In addition, high resulted more generations heavy tar considera...

Eg 1: The sodium pyrophosphate (Na-pyro) extractable data (highlighted) in Table 3 are wrong as published. The correct version of the table is given below. The error occurred in the revision phase of the manuscript (the table was correct in the first version) when the acid oxalate data were copied twice. We apologize for the mistake. The description in the manuscript is based on the correct dat...

Four different Tc-99m labeled phosphorus-based bone-imaging agents were compared by a scan-evaluation technique in which the skeletal uptake was visually assessed at selected sites. A detailed statisticalanalysis of scans, by each of three independent evaluators, on a total of 140 different patients showed that two of the agents (based on pyro- and on trimetaphosphate) were superior. The statis...

The effects of various chemical and enzymatic treatments on the biological activity of porcine luteinizing hormone-releasing hormone (LH-RH) are described. This experiment was performed before the elucidation of the structure of LH-RH. LH-RH activity was abolished by the following endopeptidases: chymotrypsin, subtilisin, papain, and thermolysin, but not by pepsin or trypsin. Exopeptidases d...

Sodium pyrophosphate (pyro-P, Na4P2O7), sodium tripolyphosphate (tripoly-P, Na5P3O10), and sodium hexametaphosphate (meta-P, (NaPO3)6) were selected as the model compounds of condensed phosphate to investigate the adsorption behavior of condensed phosphate on aluminum hydroxide. The adsorption was found to be endothermic and divisible into two stages: (1) fast adsorption within 1 h; and (2) slo...

Abstract In this article, the damped nonlinear transient response of a smart sandwich plate (SSP) comprising agglomerated CNT-reinforced porous nanocomposite core with multifunctional magneto-piezo-elastic (MPE) facesheets, subjected to thermal environment, is numerically investigated. The synergistic influence agglomeration, porosity and pyro-coupling on vibration control studied for first tim...
