Population Balance Discretization for Growth, Attrition, Aggregation, Breakage and Nucleation
This paper presents a new discretization method to solve the population balance equation (PBE) for batch and unsteady/steady-state continuous perfectly-mixed systems. The numerical technique is valid for any size change ...
Characterization Of Particle Size Of Polydispersed Biomass By Mechanical SievingCaracterização Granulométrica De Biomassa Polidispersa Pelo Método De Peneiramento Mecânico
(Sociedade Brasileira de Engenharia Agricola, 2016)
X̄ chart with variable sample size and sampling intervals
Recent theoretical studies have shown that the X̄ chart with variable sampling intervals (VSI) and the X̄ chart with variable sample size (VSS) are quicker than the traditional X̄ chart in detecting shifts in the process. ...
From Amino Acids to Nature-Inspired Molecular Scaffolds: Incorporation of Medium-Sized Bridged Heterocycles into a Peptide Backbone
(American Chemical Society, 2014-10)
Novel molecular scaffolds comprising two to four bridged and fused heterocycles were synthesized from amino acids using seven-membered endocyclic N-acyliminium ions as key intermediates in acid-mediated tandem reactions ...

Corn texture and particle size in broiler diets
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-12-01)
The objective of this study was to evaluate the effect of corn texture and the particle size on broiler performance, carcass yield, nutrient digestibility, and digestive organ morphometrics. In Experiment I, 720 male Cobb ...
Copy number of P elements, KP/full-sized P element ratio and their relationships with environmental factors in Brazilian Drosophila melanogaster populations
(Nature Publishing Group, 2003-12-01)
The P transposable element copy numbers and the KP/full-sized P element ratios were determined in eight Brazilian strains of Drosophila melanogaster. Strains from tropical regions showed lower overall P element copy numbers ...
Size-fecundity relationships and reproductive investment in female frogs in the Pantanal, south-western Brazil
The ovarian complement of anurans exhibiting different reproductive modes is highly diverse, and intraspecific variation in reproductive output of anurans is generally related to variation in female properties and/or ...
The evolution of brain size and organization in vertebrates. A program for research
In vertebrates, brain size variability relates to two main parameters: body size and ecological factors (in particular diet and foraging strategy). It has been considered by many authors that evolutionary brain growth is ...
Relationship between scintillation properties and crystallite sizes in Y2O3:Eu3+
This work describes the relation between crystallite size and scintillation properties of Eu3+-doped yttrium oxide. Nanocrystalline Y2O3:Eu3+ 1.0 mol% powders were prepared by Pechini method and thermal treated at 700–1100 ...
