model of production is considered, in which the production unit adjusts the relative weights of capital and production labor in the input index as input prices vary. The variation in relative input price across plants is the main determinant that explains the di erences in capital-labor ratio and the relative revenue shares of the two inputs.

Pozzolana, also known as pozzolanic ash, is a fine, sandy volcanic ash, originally discovered and dug in Italy at Pozzuoli in the region around Vesuvius, but later at a number of other sites. Vitruvius speaks of four types of pozzolana: black, white, grey and red, all of which can be found in the volcanic areas of Italy, such as Naples. Pozzolana is a siliceous and aluminous material which ...
The yield production was significantly higher on PZ (53 t ha-1) with respect to PR and GR (38-39 t ha-1); also the average fruit weight was higher on PZ (1200 g) with respect to the other two substrates (900-980 g). In the melon crop, the plant dry weight was higher on the plants grown on PZ, while the root dry weight was higher on PZ and PR.
This work deals with anomalous concentrations of natural mordenite in the southeast of Spain. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies evidenced that the samples contain mainly monomineral zeolitic phase of mordenite (70% to 74%), usually accompanied by smectite (montmorillonite), the principal component of bentonite.
Jan 18, 2021· A pozzolana is a material which, when mixed with a hydraulic cement, will react with the lime from the cement and water to produce cementitious hydration products of its own. The most familiar types of pozzolanic materials in common use are low-limed fly ash and silica fume, which are the residues from other industrial processes.
