An alternative "no resection" technique for posterior mitral leaflet prolapse repair: Reverse T-plasty
(Lippincott Williams and Wilkins, 2014)
Reverse T-plasty is an alternative "no resection" technique for posterior mitral leaflet prolapse repair that is inspired by butterfly resection. It combines mediolateral and anteroposterior plane foldings of the posterior ...
Reproductive biology of Grey-breasted Wood-Wren (Henicorhina leucophrys): A comparative study of tropical and temperate wrens
(Wilson Ornithological Society, 2019)
We provide a detailed breeding biology account for the Grey-breasted Wood-Wren (Henicorhina leucophrys) and a comparison of the reproductive life history of tropical and temperate wrens using literature data. We conducted ...
Synthesis of Ion-Imprinted Bioadsorbents Based on Chitosan and its Usage in Al(III) Removal
(Springer New York LLC, 2018)
As a main goal of the study, a new Al(III) ion-imprinted (Al(III)-IP) bioadsorbent beads were synthesized through crosslinking of chitosan (CS) by epichlorohydrin (ECH) using ion-imprinting strategy and the selective Al(III) ...
The removal of acid violet 90 from aqueous solutions using PANI and PANI/clinoptilolite composites: Isotherm and kinetics
(Springer New York LLC, 2018)
Polyaniline (PANI) and polyaniline/Gördes-clinoptilolite (PANI/GC) composite materials were synthesized by the chemical oxidative polymerization technique and used in the adsorption of Acid Violet 90 metal-complex dye (AV ...
ARMA(p,q) type high order fuzzy time series forecast method based on fuzzy logic relations
(Elsevier Ltd, 2017)
Within classic time series approaches, a time series model can be studied under 3 groups, namely AR (autoregressive model), MA (moving averages model) and ARMA (autoregressive moving averages model). On the other hand, ...
Mechanical characterization of ruthenocuprates by nanoindentation technique
(Springer New York LLC, 2014)
The nanomechanical properties of RuSr 2 RECu 2O8 (RE = Eu, Gd and Ho) prepared by ammonium nitrate melt technique (ANMT) were investigated using nanoindentation technique. The indentation load–displacement curves of the ...
Synthesis of Ion-Imprinted Alginate Based Beads: Selective Adsorption Behavior of Nickel (II) Ions
(Springer New York LLC, 2018)
Ni(II) imprinted and non-imprinted bioadsorbent alginate beads were prepared, and utilized in the selective adsorption of Ni(II) ions. The optimum adsorption capacity were 6.00 mmol g?1 at 500 ppm initial metal ion ...
Magneto optical properties and hperfine interactions of Cr3+ Ion substituted copper ferrite nanoparticles
(Springer New York LLC, 2018)
Spinel CuCrxFe2−xO4 (0.0 ≤ y ≤ 1.0) nanoparticles were fabricated by co-precipitation. X-ray diffraction proved the pureness and cubic crystal assembly of products which have the crystallite sizes varying between 16 and ...
Magnetic properties of FeMnyCoyFe2−2yO4@Oleylamine nanocomposite with cation distribution
(Springer New York LLC, 2017)
In this study, oleylamine (OAm) capped FeMnyCoyFe2−2yO4 (0.0 ≤ y ≤ 0.4) nanocomposites (NCs) were prepared via the polyol route and the impact of bimetallic Co3+ and Mn3+ ions on the structural and magnetic properties of ...
Structural, optical and mössbauer study of Ba1 − xCuxFe12O19 (0.5 ≤ x) nano hexaferrites
(Springer New York LLC, 2018)
In this study, a novel Ba1−xCuxFe12O19 (0.5 ≤ x) nano-hexaferrites were prepared by a simple and cost-effective sol–gel auto-combustion method using barium nitrates, iron nitrate, copper (II) acetate monohydrate and citric ...
