Synthesis and characterization of magnetite nanoparticles functionalized with organophosphorus compounds and its application as an adsorbent for La (III), Nd (III) and Pr (III) ions from aqueous solutions
(Elsevier B.V., 2019)
© 2018 In this communication, adsorbents based on functionalized magnetite nanoparticles were synthetized, characterized and evaluated as adsorbents for the uptake of La (III), Pr(III) and Nd(III) from aqueous solutions. ...
Localized states beyond the asymptotic parametrically driven amplitude equation
(AMER PHYSICAL SOC, 2008-05)
We study theoretically a family of localized states which asymptotically connect a uniform oscillatory state in the magnetization of an easy-plane ferromagnetic spin chain when an oscillator magnetic field is applied ...

Hormonal Carcinogenesis in Canine Mammary Cancer: Molecular Mechanisms of Estradiol Involved in Malignant Progression
(MDPI, 2021)
Canine mammary cancer corresponds to a tumor disease that frequently affects female dogs, especially those that are reproductively intact. This disease can decrease the survival and quality of life of affected animals; ...
Vibronic intensities in the electronic spectra of transition-metal complex ions: Part VII. The Г8(2T2g) -> Г8(4A2g) electronic transition of the ReBr2-6 ion in Cs2ZrBr6
(1990)
The vibronic intensities of the vibronic origins due to the three odd-parity vibrational modes of the Г8(2T2g) Г8(4A2g) electronic transition of the ReBr2-6 ion are calculated using both crystal-field and ligand-polarization ...
Observing gendered interdependent mobility barriers using an ethnographic and time use approach
(Elsevier, 2020)
Combining traditional transport research tools with qualitative research methods, particularly ethnography, can contribute to our understanding of the complexity of mobility strategies, particularly their gendered differences. ...
Clinical features and possible founder mutation of the 8bp duplication mutation in the SLC4A11 gene causing corneal dystrophy and perceptive deafness in three South American families
(Taylor and Francis Ltd, 2019)
Background: Corneal Dystrophy and Perceptive Deafness (CDPD) or Harboyan syndrome is an autosomal recessive rare disorder, characterized by congenital corneal opacities and progressive sensorineural hearing loss, which ...
Paternity Loss in Relation to Male Age, Territorial Behaviour and Stress in the Pied Flycatcher
(Blackwell, 2010)
For sexual selection to operate in monogamous species, males of poor
quality in some factor like age, ornamentation, condition or aggressiveness,
should lose paternity compared with higher quality males. We
tested this ...
Convergencia y polarización. El caso Peruano:1961-1996
(Universidad de Chile. Facultad de Economía y Negocios, 2002-06)
According to Growth Theory, different economies converge to the same steadystate
if saving rates, depreciation and population growth are controlled.
Controlling for other variables, convergence will be conditional and ...
