Development of a microbial biosensor based on carbon nanotube (CNT) modified electrodes
(Elsevier Science Inc, 2007)
Pseudomonas putida DSM 50026 cells were used as the biological component and the measurement was based on the respiratory activity of the cells estimated from electrochemical measurements. The cells were immobilised on ...
Improved salt tolerance of melon (Cucumis melo L.) by the addition of proline and potassium nitrate
(Pergamon-Elsevier Science Ltd, 2007)
A pot experiment was carried out under glasshouse conditions with melon (Cucumis melo) cv. "Tempo F1" in a mixture of peat, perlite and sand (1:1:1) to investigate the effects of external proline and potassium nitrate ...
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 ...
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 ...
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 ...
Decolourization and removal of some organic compounds from olive mill wastewater by advanced oxidation processes and lime treatment
(Springer Heidelberg, 2007)
Background. Olive mill wastewater (OMW) generated by the olive oil extracting industry is a major pollutant, because of its high organic load and phytotoxic and antibacterial phenolic compounds which resist biological ...
