Non-uniform size of catalyst particles. Impact on the effectiveness factor and the determination of kinetic parameters
(Elsevier Science SA, 2020-09)
The analysis of the effectiveness factor in catalytic particles with non-uniform size, was performed. The procedure proposed by Weisz and Prater to determine the intrinsic kinetic constants from experimental results was ...
Effect of amylolysis on the formation, the molecular, crystalline and thermal characteristics and the digestibility of retrograded starches
(2020-11-15)
This study evaluated the effect of amylases on the formation, and characteristics of retrograded starches using sweet potato (SPS), cassava (CAS) and high amylose maize (HAS) starches. The starches were gelatinized, ...
Chelating agent effects in the synthesis of mesoscopic-size superconducting particles
(Springer, 2008-05-01)
Several routes and procedures have been used in these last years as an effort to achieve single-phase mesoscopic-size superconducting samples. In this paper, the effects of using citric acid (CA), tartaric acid (TA) and ...
Effectiveness of corridors relative to enlargement of habitat patches
(2007)
The establishment of biological corridors between two otherwise isolated habitat patches is a common yet contentious strategy for conserving populations in fragmented landscapes. We compared the effectiveness of corridors ...

Effects of temperature and meal size on the postprandial metabolic response of Leptodactylus latrans (Anura, Leptodactylidae)
(Wiley-Blackwell, 2019-10-15)
The postprandial increment of metabolism, often referred to as specific dynamic action (SDA), encompasses the summed costs of meal ingestion, digestion, absorption, and assimilation. Different SDA parameters, such as its ...
Effects of Perspective on the Amplification of Object Sizes that Intercept the Horizon Line
(UNIV FEDERAL RIO GRANDE SULPORTO ALEGRE RS, 2012)
We investigated the effects of texture gradient and the position of test stimulus in relation to the horizon on the perception of relative sizes. By using the staircase method, 50 participants adjusted the size of a bar ...
Finite-size effects on the chiral phase diagram of four-fermion models in four dimensions
(Elsevier, 2009)
We study the size dependence of the dynamical symmetry breaking in the four-dimensional Nambu–Jona-Lasinio model. We show that the presence of boundaries reduces the chiral breaking region, and this effect is strengthened ...
