Seasonal succession of the phytoplankton community and evaluation of water quality using trophic diatom index in a stream
(Scibulcom Ltd., 2016)
Phytoplankton species composition, seasonal variation and the factors effecting the variation were studied in this study one-year period, from June 2010 to May 2011. Water samples were collected monthly from four stations. ...
Seasonal distribution of epipelic diatom assemblages and relations to environmental variables in a mesotrophic pond
(Scibulcom Ltd., 2016)
The seasonal succession of diatom species in the epipelon of shallow, mesotrophic pond OMU Pond I (Turkey) with special attention to diatoms (particularly Navicula) is described. The composition of epipelic algal assemblages ...
Fe(II)-Co(II) double salt incorporated magnetic hydrophobic microparticles for invertase adsorption
(Humana Press Inc., 2015)
Invertase (β-fructofuranoside fructohydrolase, EC 3.2.1.26) is an enzyme widely used in the food industry. Its main function is the formation of glucose and fructose through hydrolysis of sucrose. For the separation and ...
Magneto-optical investigation and hyperfine interactions of copper substituted Fe3O4 nanoparticles
(Elsevier Ltd, 2016)
CCopper substituted Fe3O4 nanoparticles (NPs) (CuxFe1−xFe2O4 (0.0≤x≤1.0)) were synthesized by polyol method and the effect of Cu2+ substitution on structural, magnetic and optical properties of Fe3O4 was investigated. X-ray ...
Dielectric properties, cationic distribution calculation and hyperfine interactions of La3+ and Bi3+ doped strontium hexaferrites
(Elsevier Ltd, 2016)
La3+ and Bi3+ doped M-type strontium hexaferrites (SrM) were prepared by sol–gel-auto combustion. X-ray powder diffraction (XRD), Scanning Electron Microscopy (SEM), Vibrating Simple Magnetometer (VSM), Mössbauer Spectroscopy ...
Structural, morphological, optical, cation distribution and Mössbauer analysis of Bi3+ substituted strontium hexaferrite
(Elsevier Ltd, 2016)
Single-phase M-type hexagonal ferrites, SrBixFe12−xO19 (0.0≤x≤1.0), were prepared by a co-precipitation assisted ceramic route. The influence of the Bi3+ substitution on the crystallization of ferrite phase has been examined ...
Structural investigation and hyperfine interactions of BaBixLaxFe12−2xO19 (0.0≤x≤0.5) hexaferrites
(Elsevier Ltd, 2016)
Barium hexaferrite, BaFe12O19, substituted by Bi3+ and La3+ (BaBixLaxFe12−2xO19 where 0.0≤x≤0.5) were prepared by solid state synthesis route. The effect of substituted Bi3+ and La3+ ions on the structure, morphology, ...
A trace formula for discontinuous eigenvalue problem
(University of Nis, 2017)
In this paper, we deal with a Sturm-Liouville problem which has discontinuity at one point and contains an eigenparameter in a boundary condition. We obtain a regularized trace formula for the problem. © 2017, University ...
Development of a HILIC method for the determination of 5-fluorouracil from nano drug delivery systems and rat skin extracts
(Elsevier B.V., 2018)
This is the first report in literature using hydrophilic interaction liquid chromatography (HILIC) in combination with diode array detector (DAD) for stability indicating determination of 5-Fluorouracil (5-FU) from its ...
Voltammetric and RP-LC assay for determination of benidipine HCl
(2012)
The detailed electrooxidative behavior of benidipine (BEN) has been studied by using glassy carbon (GC) and boron-doped diamond (BDD) electrodes. Using cyclic voltammetry, depending on the pH values and the working electrodes, ...
