Geodetic convex boundary curvatures of the communities in stock market networks
(Elsevier Science Bv, 2018)
We analyze the daily returns of stock market indices of NASDAQ and S&P 500 over the period of 2004-2015. We build network models by using a threshold method that captures strong relations amongst the agents. We also subdivide ...
Synthesis and characterization of electrospun PVA/Zn2+ metal composite nanofibers for lipase immobilization with effective thermal, pH stabilities and reusability
(Elsevier Science Bv, 2019)
Polyvinyl alcohol (PVA)/Zn2+ electrospun nanofibers that were a kind of polymer/ionic metal composite was successfully embedded in the hybrid fibers for the first time in the literature, due to chemical interactions between ...
Photoluminescence Properties of a New Sm(III) Complex/PMMA Electrospun Composite Fibers
(Springer/Plenum Publishers, 2020)
In this paper, a Sm(III) cluster-based 2D coordination polymer {[Sm(2-stp)center dot 3(H2O)]center dot(H2O)}(n), (where 2-stp = 2-sulfoterephthalate),1has been synthesized hydrothermally and doped into poly(methyl methacrylate ...
A Detailed Biological and Chemical Investigation of Sixteen Achillea Species' Essential Oils via Chemometric Approach
(Wiley-V C H Verlag Gmbh, 2020)
Representatives of the Achillea genus are widely used as foods or nutraceuticals. Considering the increasing demand for herbal dietary supplements with health promoting effects, the objective of this research was to evaluate ...
Peculiarities of thermo-morphologic and thermotropic transformations of heterophase regions: nematic <-> isotropic phase transition in 4-n-Alkyl-4 '-cyanobiphenyl mesogens
(Natl Inst Optoelectronics, 2019)
Important peculiarity of phase transitions in liquid crystalline materials is availability of the heterophase regions, in which low temperature and high temperature phases simultaneously take place. In this work, peculiarities ...
Regimes of current transport mechanisms in CdS/CdTe solar cells
(Iop Publishing Ltd, 2019)
Forward bias recombination (current transport) mechanisms have been evaluated for thin film solar cells and correlated to the in-gap trap levels present. Here CdTe/CdS devices were chosen as an archetypal example of a ...
Urease immobilized electrospun PVA/chitosan nanofibers with improved stability and reusability characteristics: an application for removal of urea from artificial blood serum
(Taylor & Francis Inc, 2020)
Electrospun polyvinyl alcohol (PVA)/Chitosan nanofibers were successfully prepared and were used as carriers for the first time in urease immobilization. Also, urease immobilized electrospun PVA/Chitosan nanofibers were ...
Lyotropic liquid crystalline hexagonal mesophase. Thermo-morphologic and magneto-morphologic transformations, electrical conductivity and optical refractive properties: Effect of optically active compounds
(Elsevier, 2020)
Mesophase chirality in lyotropic liquid crystalline hexagonal E mesophase, which is formed by the anisometric micelles with quasi-infinite length, was studied. Effect of the optically active dopants {tartaric acid (TA) and ...
Peculiarities of Defective Formations in Heterophase Regions of the Thermotropic Phase Transitions in Liquid Crystals
(Wiley-V C H Verlag Gmbh, 2019)
A unique feature of phase transitions in liquid crystalline materials is the availability of heterophase regions. In such regions, the simultaneous coexistence of high temperature and low temperature phases takes place. ...
High-frequency protocorm-like bodies and shoot regeneration through a combination of thin cell layer and RITA((R)) temporary immersion bioreactor in Cattleya forbesii Lindl.
(Springer, 2019)
An efficient in vitro mass propagation through protocorm-like bodies (PLBs) was established in Cattleya forbesii Lindl., a commercially important orchid. Whole PLBs (W-PLB) and transverse thin cell layers of PLB (tTCL-PLB) ...
