Ring- and side-group conformational properties of di-O-acylated xylopyranosides: A computational study
(Elsevier, 2015)
The conformational properties (C-4(1), C-1(4), and skew ring structures, side chain torsion) of methyl 2,4-(1) and 3,4-O-diacetyl (2) as well as 2,4-(3) and 3,4-O-dibenzoyl (4)-SS-D-xylopyranoside are calculated by ...
Electronic features and hydrogen bonding capacity of the sulfur acceptor in thioureido-based compounds. Part 2. Further insight by theoretical charge density study
(Elsevier, 2015)
Theoretical charge density analysis of the thioureido based compound 4-methyl-3-thiosemicarbazide (MeTSC) is used in this study with the aim to provide additional insight into electronic features of the thioureido sulfur ...
Bioactive Compounds in Wild, In vitro Obtained, Ex vitro Adapted, and Acclimated Plants of Centaurea davidovii (Asteraceae)
(Natural Products Inc, Westerville, 2015)
In vitro cultures were initiated from a single seed of Centaurea davidovii. Whole plantlets were regenerated and cultivated for several months on agar-solidified nutrient media differing by their composition: basal MS ...
Characteristics and catalytic behavior of supported NiMgAg/D catalysts in the partial hydrogenation of soybean oil
(Springer Netherlands, 2015)
Diatomite supported NiMgAg catalysts, NiMgAg/D, were prepared by the precipitation-deposition method followed by drying, reduction and passivation. The preparation of the catalysts was performed with different loading of ...
In situ videometry monitoring of bubble behavior during the electrocatalytic oxygen evolution reaction
(Springer Netherlands, 2015)
Cyclic voltammetry (CV) on rotating Pt disc electrode was used for electrocatalytic oxidation of OH-. Hydroxide ion oxidation is followed by oxygen evolution with gas bubble formation. The image analysis was performed in ...
High Levan Production by Bacillus licheniformis NS032 Using Ammonium Chloride as the Sole Nitrogen Source
(Humana Press Inc, Totowa, 2015)
In this study, levan production by Bacillus licheniformis NS032 isolated from a petroleum sludge sample was investigated. High levan yield was obtained in a wide range of sucrose concentrations (up to 400 g/L) and, contrary ...
New Experimental and Mechanistic Investigation on the KSCN-H2O2-NaOH-Cu(II)-Catalyzed Oscillating System (Orban-Epstein Reaction): Inhibitory Effects by Diphenols
(Wiley-Blackwell, Hoboken, 2015)
The KSCN-H2O2-NaOH-Cu(II)-catalyzed system is one of the few reactions in which chemical oscillations can be observed in batch conditions. In the present paper, this oscillating reaction was revisited in a wide range of ...
Low-pass filter with deep and wide stop band and controllable rejection bandwidth
(Cambridge Univ Press, Cambridge, 2015)
Novel design of low-pass microwave filters based on cascading of identical unit cells is proposed. Dispersion relation is used to determine the cell parameters for a given relative stop-band width. For a filter consisting ...
Implications of oxidative stress in occupational exposure to lead on a cellular level
(Taylor & Francis Ltd, Abingdon, 2015)
The aim of this study was to determine oxidative alterations leading to cellular dysfunctions in Pb-exposed subjects by evaluating damage to all major classes of biomolecules in the cell, lipid peroxidation, protein and ...
An Assessment of the Chemical Characteristics of Early Diagenetic Processes in a Geologically Well-defined Brown Coal Basin
(Taylor & Francis Inc, Philadelphia, 2015)
The characteristics of early diagenetic processes, which influenced the composition of the organic matter of coals from the Krepoljin coal basin, Serbia, Miocene age was assessed by statistical correlation analysis and ...
