Greenhouse gas (GHG) emissions in the Sultanate of Oman
(
Society of Chemical Industry and John Wiley & Sons, Ltd
, 2015 , Article)
Worldwide, many countries are being affected by greenhouse gas (GHG) emissions. The Sultanate of Oman is no exception. In Oman, both oil- and natural-gas-related activities have the most important shares of the nation's ...
Correlated Multiple Antennas Spectrum Sensing under Calibration Uncertainty
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
We address the problem of spectrum sensing in cognitive radios (CRs) when the secondary user (SU) is equipped with a multiantenna receiver. We consider scenarios with correlation between the received channels at different ...
Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
(
AIChE
, 2015 , Conference Paper)
Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ...
High voltage pulse generator based on DC-to-DC boost converter with capacitor-diode voltage multipliers for bacterial decontamination
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
High voltage pulse generators can be used effectively in water treatment applications, as applying a pulsed electric field on the infected sample guarantees killing of harmful germs and bacteria. In this paper, a new high ...
Impact of a pharmacy practice research capacity-building programme on improving the research abilities of pharmacists at two specialised tertiary care hospitals in Qatar: a preliminary study
(
John Wiley & Sons, Ltd.
, 2015 , Article)
The aim of this study was to develop and implement a pharmacy practice research training programme and to determine the effect of the programme on pharmacists' knowledge of, and attitudes towards, research. An intensive ...
Dynamic mechanical properties of PLA/PHBV, PLA/PCL, PHBV/PCL blends and their nanocomposites with TiO2 as nanofiller
(
Elsevier
, 2015 , Article)
The effect of blending and the addition of small amounts of TiO2 nanoparticles on the dynamic mechanical properties of PLA/PHBV, PLA/PCL and PHBV/PCL blends is reported in this paper. The storage modulus of the PLA/PHBV ...

PEGylated graphene oxide for tumor-targeted delivery of paclitaxel
(
Future Medicine Ltd.
, 2015 , Article)
Aim: The graphene oxide (GO) sheet has been considered one of the most promising carbon derivatives in the field of material science for the past few years and has shown excellent tumor-targeting ability, biocompatibility ...
Sol-gel deposition and plasma treatment of intrinsic, aluminum-doped and gallium-doped zinc oxide thin films as transparent conductive electrodes
(
SPIE
, 2015 , Conference Paper)
Zinc oxide and aluminum/gallium-doped zinc oxide thin films were deposited via sol-gel spin-coating technique. Employing plasma treatment as alternative to post thermal annealing, we found that the morphologies of these ...
On the Performance of Hadamard Ratio Detector-Based Spectrum Sensing for Cognitive Radios
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
We consider the problem of multiantenna spectrum sensing (SS) in cognitive radios (CRs) when the receivers are assumed to be uncalibrated across the antennas. The performance of the Hadamard Ratio Detector (HRD) is analyzed ...
