Effect of octylphenol polyethylene oxide on the corrosion inhibition of steel in 0.5 M H2SO4
(
Elsevier
, 2004 , Article)
A non-ionic surfactant, octylphenol polyethylene oxide (OPPEO), was evaluated as an inhibitor for corrosion of low-carbon steel in 0.5M H 2SO4. Potentiodynamic and potentiostatic methods and scanning electron microscopy ...
Poisonous plants contaminating edible ones and toxic substances in plant foods IV. Phytochemistry and toxicity of lolium temulentum
(
Taylor & Francis
, 2008 , Article)
Different procedures were carried out for the preparation and separation of the total alkaloids of Lolium temulentum. Loline has been identified as the major pyrrolizidine alkaloid of the seeds. The toxicity of the alcoholic ...
Efficient visual mixture design of experiments using property clustering techniques
(2009 , Article)
Mixture design is a design of experiments (DOE) tool used to determine the combination of chemical constitutents that deliver a desired response (or property) using a minimum number of experimental runs. While the approach ...
Financial progress and the stability of long-run money demand: Implications for the conduct of monetary policy in emerging economies
(
Elsevier Inc.
, 2009 , Article)
This paper examines whether recent financial changes in three emerging market economies in the Gulf region (Bahrain, the UAE, and Qatar) have distorted the character and the stability of their underlying long-run money ...
Three-body effects in the annihilation of positrons on molecules
(
APS
, 2002 , Article)
The three body effects in the annihilation of positrons on molecules were discussed. The positron annihilation in ethylene gas at room temperature and at densities below one amagat, showed that the mean free positron ...
On certain rough integral operators and extrapolation
(
Victoria university
, 2009 , Article)
In this paper, we obtain sharp Lp estimates of two classes of maximal operators related to rough singular integrals and Marcinkiewicz integrals. These estimates will be used to obtain similar estimates for the related ...
Stratigraphy and sedimentology of the Hofuf Formation in the State of Qatar in relation to the tectonic evolution of the East Arabian Block
(
Sultan Qaboos University
, 2002 , Article)
Well-exposed, fine-grained to pebbly coarse-grained fluvial sandstones of Late Miocene to Pleistocene age crop out in the south-central and south-western parts of Qatar. These sandstones belong to the Hofuf Formation and ...
Park's transformation application for power system harmonics identification and measurements
(
Taylor & Francis
, 2003 , Article)
This paper presents the application of Park's transformation for identifying and measuring power system harmonics. One of the advantages of the proposed technique is that it does not need a model for the harmonics components ...
Novel thorium membrane sensors with anionic response based on trioctylphosphine oxide and toluate ionophores
(
Wiley-VCH Verlag
, 2008 , Article)
Two novel potentiometric polymeric membrane sensors for rapid and accurate determination of thorium are described. These are based on the use of trioctylphosphine oxide (TOPO) and thorium toluate (Th-TA) as ionophores ...
Thermalization times of positrons in molecular gases
(2000 , Article)
The time that a particle takes to reach thermal equilibrium in gas is a gross measure of the efficiency with which such particle can exchange its kinetic energy with the medium. The time taken for positrons to reach thermal ...
