The Conditional Heterocedasticity on the Argentine Inflation: An Analysis for the Period from 1943 to 2013
(David Publishing, 2017-10)
Numerous economic time series do not have a constant mean and in practical situations, we often see that the variance of observational error is subject to a substantial variability over time. This phenomenon is known as ...
Typical experiment vs. in-cell like conditions in magnetic hyperthermia: Effects of media viscosity and agglomeration
(Elsevier Science, 2019-12-01)
Magnetic nanoparticles (MNPs) can be used to transform electromagnetic energy into heat in hyperthermic treatment of cancer and other thermally activated therapies. The MNPs heating efficiency depends strongly on the ...
Is the variation of floral elaiophore size in two species of Stigmaphyllon (Malpighiaceae) dependent on interaction with pollinators?
(Taylor & Francis Ltd, 2017-11)
Background: Intraspecific variations in floral traits of species over its geographic range can be associated with differences in pollinator assemblages and/or with environmental conditions. Aims: We evaluated the area of ...
Modelling respiration rate of soybean seeds (Glycine max (L.)) in hermetic storage
(2017-12)
The dynamic of oxygen (O2) and carbon dioxide (CO2) concentration was characterized in soybean (Glycine max (L.)) samples hermetically stored in glass jars at 15, 25 and 35 °C and 13, 15 and 17% moisture content (m.c., wet ...
Attraction of Triatoma infestans (Klug) to adhesive yeast-baited trap under laboratory conditions
(Springer, 2020-01-02)
Existing methods to detect domestic triatomines have low sensitivity. As early house infestation detection is epidemiologically important, the exploration of better methods is required. Hence, we measured the attractiveness ...
Chiral separation of several pesticides on an immobilized amylose tris(3-chloro-5-methylphenylcarbamate) column under polar-organic conditions: influence of mobile phase and temperature on enantioselectivity
(Elsevier, 2020-08)
In this work, the use of different solvents and temperatures was explored, aiming to evaluate their influence on the enantioseparation of pesticides by HPLC in polar-organic conditions, employing a column containing ...
Bubble nucleation and growth in slow cosmological phase transitions
(Elsevier Science, 2018-03)
We study the dynamics of cosmological phase transitions in the case of small velocities of bubble walls, vw<0.1. We discuss the conditions in which this scenario arises in a physical model, and we compute the development ...
Stoichiometry of sulfite oxidation by oxygen during the determination of the volumetric mass transfer coefficient
(American Chemical Society, 2008-12)
The aim of this work was to study the effect of the initial sulfite concentration on the stoichiometric coefficient of sulfite oxidation. A combined method based on the oxidation of sulfite by oxygen in the presence of ...
Cascades, thermalization, and eddy viscosity in helical Galerkin truncated Euler flows
(American Physical Society, 2009-12)
The dynamics of the truncated Euler equations with helical initial conditions are studied. Transient energy and helicity cascades leading to Kraichnan helical absolute equilibrium at small scales, including a linear scaling ...
Taxonomic and functional β-diversity of ants along tree plantation chronosequences differ between contrasting biomes
(Elsevier Gmbh, Urban & Fischer Verlag, 2019-12)
The replacement of natural by anthropogenic habitat changes biological communities in any biome. Variations in environmental conditions along the chronosequence of tree plantations may act as a gradient of environmental ...
