Photo-oxidative enhancement of polymeric molecular sieve membranes
(
Nature Research
, 2013 , Article)
High-performance membranes are attractive for molecular-level separations in industrial-scale chemical, energy and environmental processes. The next-generation membranes for these processes are based on molecular sieving ...
High pressure CO2 absorption studies on imidazolium-based ionic liquids: Experimental and simulation approaches
(2013 , Article)
A combined experimental-computational study on the CO2 absorption on 1-butyl-3-methylimidazolium hexafluophosphate, 1-ethyl-3-methylimidazolium bis[trifluoromethylsulfonyl]imide, and 1-butyl-3-methylimidazolium ...
Determinants of segmental disclosures: evidence from the emerging capital market of Jordan
(
Inderscience
, 2013 , Article)
The primary objective of this paper is to examine the factors which
affect the segmental disclosures (mandatory and voluntary) provided by
Jordanian listed companies. In addition, the study documents evidence about
the ...
The Qatar National Professional Standards for School Leaders: a critical discourse analysis using Habermas’ theory of knowledge constitutive interests
(
Taylor & Francis
, 2013 , Article)
Qatar is in the midst of a massive educational reform, Education for a New Era. Influence
by neoliberalism, one principle of the reform is the development of a standards-based
system including the adoption of the Qatar ...
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
(
Wiley Online Library
, 2013 , Article)
In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ...
Chemical composition and evaluation of antioxidant and antimicrobial activities of Tunisian Thymelaea hirsuta with special reference to its mode of action
(
Elsevier B.V.
, 2013 , Article)
In the present study, we evaluated in vitro antimicrobial and antioxidant properties of Thymelaea hirsuta extracts as well as its phytochemical composition. Total phenolic and flavonoid contents were highest in acetone and ...
Moisture and temperature dependence of the dielectric properties of pharmaceutical powders
(2013 , Article)
The dielectric properties of pharmaceutical powder–(paracetamol, aspirin, lactose, maize starch, adipic acid) solvent (water) mixtures were measured at 2,450 MHz at a range of moisture contents (0–1.0 kg kg−1, dry basis) ...
Microstructure, thermal and mechanical response of AZ51/Al2O3 nanocomposite with 2 wt.% Ca addition
(
Elsevier, Ltd
, 2013 , Article)
In the present study, new AZ51/Al2O3–2Ca magnesium nanocomposite was successfully synthesized by simultaneously adding 2wt.% aluminum, 2wt.% Ca and 1.5vol.% nanosized Al2O3 (50nm) into AZ31 matrix using a disintegrated ...
An improved palmprint recognition system using iris features
(
Springer
, 2013 , Article)
This paper presents a bimodal biometric recognition system based on the extracted features of the human palmprint and iris using a new graph-based approach termed Fisher locality preserving projections (FLPP). This new ...
Design of thin wall structures for energy absorption applications: Enhancement of crashworthiness due to axial and oblique impact forces
(2013 , Article)
This paper describes a computationally aided design process of a thin wall structure subject to dynamic compression in both axial and oblique directions. Several different cross sectional shapes of thin walled structures ...
