Antioxidant activity of stem and root extracts of Rhubarb (Rheum ribes): An edible medicinal plant
(Elsevier Sci Ltd, 2007)
The antioxidant activity of chloroform and methanol extract of roots and stems of Rhubarb (Rheum ribes L.), which are used for medicinal purposes and also its fresh stems and petioles are consumed as vegetable, was studied. ...
Antioxidant abietane diterpenoids from Salvia barrelieri
(Elsevier Sci Ltd, 2007)
The root extract of endemic Algerian Salvia species Salvia barrelieri Ettling and its diterpenoids were investigated for potential antioxidant activity. From its acetone extract, a new natural abietane diterpenoid ...
Examination of performance of glassy carbon paste electrode modified with gold nanoparticle and xanthine oxidase for xanthine and hypoxanthine detection
(Elsevier, 2007)
A composite electrode was prepared by modifying glassy carbon microparticles with gold nanoparticles (Au-nps) and xanthine oxidase enzyme (XOD) for xanthine (X) and hypoxanthine (Hx) detection. After the optimization of ...
Electronic aspects of the martensitic transition in Ni-Mn based Heusler alloys
(Elsevier, 2007)
The martensitic transformation temperature Ms depends linearly on the valence electron concentration for Ni-Mn-X Heusler systems where X is a group III-group V element. However, the slopes of the linearity are different ...
Measurement of destination brand bias using a quasi-experimental design
(Elsevier Sci Ltd, 2007)
Image of a country as tourism destination brand can involve a biased or distorted view that is different from its objective reality. Although several destination image studies make references to negative destination images ...
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 ...
Some physical, wood polymer biological, mechanical, and fire properties of composite (WPC) pretreated with boric acid and borax mixture
(Elsevier Sci Ltd, 2007)
Wood polymer composite (WPC) was obtained by vinyl monomers such as styrene (ST), methylmethacrylate (MMA), and their mixture (50:50; volume:volume) of treated sapwood of Scots pine (Pinus sylvestris L.). Boric acid (BA) ...
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 ...
An Analytical Network Process (ANP) evaluation of alternative fuels for electricity generation in Turkey
(Elsevier Sci Ltd, 2007)
In this paper, we present an Analytical Network Process (ANP) model to determine the best fuel mix for electricity generation in Turkey from a sustainable development perspective. The proposed model is implemented in two ...
A Taylor method for numerical solution of generalized pantograph equations with linear functional argument
(Elsevier Science Bv, 2007)
This paper is concerned with a generalization of a functional differential equation known as the pantograph equation which contains a linear functional argument. In this paper, we introduce a numerical method based on the ...
