A new flavone from antioxidant extracts of Pistacia terebinthus
(Elsevier Sci Ltd, 2007)
Acetone and methanol extracts of the fruits of Pistacia terebinthus L. subsp. terebinthus L. were studied for their antioxidant activity by investigating their total phenolic and flavonoid contents, P-carotene bleaching ...
New perylene derivative dyes for dye-sensitized solar cells
(Elsevier, 2007)
We have studied the influence of the spacer alkyl chain length of perylenemonoimide (PMI) dyes on the device performance in dye-sensitized solar cells (DSSCs). We observed that the dyes with longer and brunched alkyl chains ...
Determination of chemical profile, antioxidant, DNA damage protection and antiamoebic activities of Teucrium polium and Stachys iberica
(Elsevier Science Bv, 2011)
This work deals with the evaluation of in vitro antioxidant, DNA preventing and antiamoebic activities of the water extracts of Teucrium polium and Stachys iberica. In all systems, T. polium extract exhibited excellent ...
Studies on the antioxidant activity of the essential oil and methanol extract of Marrubium globosum subsp globosum (lamiaceae) by three different chemical assays
(Elsevier Sci Ltd, 2008)
This study is designed to examine the chemical composition and in vitro antioxidant activity of the essential oil and sub-fractions of the methanol extract of Marrubium globosum subsp. globosum. The GC and GC-MS analysis ...
Biosorption of Cr(III) from solutions using vineyard pruning waste
(Elsevier Science Sa, 2010)
The kinetics and biosorption mechanism of Cr(III) ions on vineyard pruning waste (VPW) have been studied using different parameters such as initial concentration, biosorbent dosage, temperature, contact time and solution ...
Legendre polynomial solutions of high-order linear Fredholm integro-differential equations
(Elsevier Science Inc, 2009)
In this study, a Legendre collocation matrix method is presented to solve high-order Linear Fredholm integro-differential equations under the mixed conditions in terms of Legendre polynomials. The proposed method converts ...
Fluorene-Carbazole Dendrimers: Synthesis, Thermal, Photophysical and Electroluminescent Device Properties
(Wiley-V C H Verlag Gmbh, 2010)
Novel hole-transporting dendrimeric molecules containing dioctylfluorene, spirobi(fluorene) and spiro(cylododecane-fluorene) as the core unit and different numbers of carbazole and thiophene moieties as the peripheral ...
Identification and characterization of a glycosaminoglycan recognition element of the C chemokine lymphotactin
(Amer Soc Biochemistry Molecular Biology Inc, 2004)
Chemokine-mediated recruitment of leukocytes in vivo depends on interactions with cell surface glycosaminoglycans. Lymphotactin, the unique member of the "C" chemokine subclass, is a highly basic protein that binds heparin, ...
Occurrence of resistance to antibiotics, metals, and plasmids in clinical strains of Staphylococcus spp
(Elsevier Science Inc, 2003)
Background. Presence of staphylococci resistant to antibiotics is of concern, as is the possible spread of resistance determinants among Staphylococcus species. During the past several years, a series of staphylococcal ...
Kinetic analysis of reactive blue 221 adsorption on kaolinite
(Elsevier, 2010)
The use of cheap, efficient and ecofriendly adsorbent has been studied as an alternative source of activated carbon for the removal of dyes from wastewater. This study has investigated the potential use of kaolinite as ...
