A new type of sesqiterpene lactone isolated from artemisia annua L. arteannuin B
(Elsevier, 1973)
The structure of a new sesquiterpene lactone, arteannuin B, isolated from Artemisia annua L. is reported.
Biodegradation of the aromatic fraction from petroleum diesel fuel by Oerskovia sp. followed by comprehensive GC x GC-TOF MS
(Elsevier, 2019)
Polycyclic aromatic hydrocarbons (PAHs) from petroleum and fossil fuels are one of the most dominant pollutants in the environment. Since aromatic fraction from petroleum diesel fuel is mainly composed of PAHs, it is ...
The comparison of sample extraction procedures for the determination of cations in soil by IC and ICP-AES
(Versita, Warsaw, 2011)
This paper presents the extraction of cations from a soil sample, type ranker on serpentinite, in deionized water, by use of three different extraction techniques. The first extraction technique included the use of a rotary ...
The effect of a localized deformation upon the common-emitter transistor current gain
(Elsevier, 1971)
Starting from the theory of the influence of pressure upon the semiconductor band diagram, and the Kroemer's proof of existence of different forces Fn and Fp acting upon the electrons and holes, a system of equations is ...
Oblique surface waves at an interface between a metal-dielectric superlattice and an isotropic dielectric
(IOP Publishing, 2012)
We investigate the existence and dispersion characteristics of surface waves that propagate at an interface between a metal-dielectric superlattice and an isotropic dielectric. Within the long-wavelength limit, when the ...
Geometrical and energetic characteristics of Se⋯Se interactions in crystal structures of organoselenium molecules
(Royal Society of Chemistry, 2021)
Non-covalent selenium-selenium interactions between selenium-containing organic molecules were studied in crystal structures from the Cambridge Structural Database and by high-level quantum chemical calculations. Se⋯Se ...
Studies on electrochemical oxidation of azithromycin and Hemomycin (R) at gold electrode in neutral electrolyte
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
The aim of the present study was to examine the oxidative properties and an assay of azithromycin and Hemomycin (R) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry. The maximum value of the ...
Lupane Triterpenoids—Betulin and Betulinic acid derivatives induce apoptosis in tumor cells
(Netherlands : Springer, 2011)
In the present investigation the antiproliferative
activity of thirteen derivatives of betulinic acid and
betulin was tested against five different tumor cell lines.
The toxicity against normal human fibroblasts
(WWO70327) ...
Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...
Essential oil of achillea coarctata
(Taylor & Francis, 1999)
Essential oil of Achillea coarctata Poir. was investigated for yield and composition. Sixty identified compounds in the oil constituted 79-3% of the oil. The main compounds of the oil were: caryophyllene oxide (9.0%), ...
