Effect of raw material milling on ceramic proppants properties
(Elsevier Science, 2018-03)
Low density and high breakage resistance ceramic proppants were developed from kaolin, bauxite and monoaluminum phosphate (MAP). The effect of the particle size on the raw materials over the density, the open porosity and ...
Soil density evaluated by spectral reflectance as an evidence of compaction effects
(TAYLOR & FRANCIS LTD, 2010)
Soil compaction, reflected by high bulk density, is an environmental degradation process and new technologies are being developed for its detection. Despite the proven efficiency of remote sensing, it has not been widely ...
The Stellar Density in High Mass Star Forming Regions
(Sydney, 2003)
Recent theoretical work has suggested that massive stars may form through the collisional agglomeration of lower mass stars in the dense centers of young stellar clusters. Densities in excess of 100 million stars per cubic ...
Coulomb gauge quark model, vacuum condensates and high density quark matter
(American Institute of Physics (AIP), 2002-01-01)
We consider here a Coulomb gauge quark model which includes an explicit construct for a nontrivial vacuum structure in QCD at finite density. Non-perturbative renormalization of ultraviolet diverges is performed by adding ...
Modeling and estimation of production rate for the production phase of non-growth-associated high cell density processes
(Springer, 2015-10)
This paper addresses the estimation of the specific production rate of intracellular products and the modeling of the bioreactor volume dynamics in high cell density fed-batch reactors. In particular, a new model for the ...
'Ray Ruby' Grapefruit Affected by Huanglongbing II. Planting Density, Soil, and Foliar Nutrient Management
(Amer Soc Horticultural Science, 2020-09-01)
Since the arrival of Huanglongbing (HLB) disease in Florida, several management approaches, including modification of orchard architecture design and nutritional therapy, have been explored. High-density plantings anticipate ...
Antioxidant activity of Argentine propolis extracts
(Elsevier Ireland, 2001-12)
Propolis is used in Argentine folk medicine. We have examined its possible protective action against oxidative modification of lipid in unfractionated serum. The kinetics of copper-induced oxidation was continuously monitored ...
Mechanisms affecting population density in fragmented habitat
(RESILIENCE ALLIANCE, 2005-06)
We conducted a factorial simulation experiment to analyze the relative importance of movement pattern, boundary-crossing probability, and mortality in habitat and matrix on population density, and its dependency on habitat ...
