Life cycle assessment of particulate recycled low density polyethylene and recycled polypropylene reinforced with talc and fiberglass
(
Trans Tech Publications Ltd
, 2011 , Conference Paper)
Although recycled polymers and reinforced polymer composites have been in use for many years there is little information available on their environmental impacts. The goal of the present study is to analyze the environmental ...
Time-Frequency Characterization of Tri-Axial Accelerometer Data for Fetal Movement Detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a significant problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity and its well-being. Using data acquired by accelerometry sensors, we ...
Analysis of cell spectral efficiency of infrastructure relay-enhanced cellular system
(
IEEE
, 2011 , Conference Paper)
In this paper, we investigate the downlink spectral efficiency of infrastructure relay-enhanced cellular systems. In particular, we use the average achieved spectral efficiency at an arbitrary mobile receiver in presence ...
Relationship between plasmid loss and gene expression in Bacillus thuringiensis
(
Springer-Verlag
, 2011 , Article)
The large genome of Bacillus thuringiensis was shortened by provoking plasmid loss, and the effect of such loss on the expression of both chromosomal and plasmid-harboured genes was studied. It was evidenced that the genomic ...
Amidoximes: Promising candidates for CO 2 capture
(
Royal Society of Chemistry
, 2011 , Article)
Monoethanolamine (MEA) dominates power plant carbon dioxide (CO 2) scrubbing processes, though with major disadvantages such as a 8-35% energy penalty. Here we report that structurally comparable amidoximes are promising ...
An analytic process model for selection of infectious waste management contractors
(
Inderscience Publishers
, 2011 , Article)
Infectious or bio-medical waste so far has not received its due attention. Hospitals in developing countries dispose large amounts of medical waste inefficiently, creating potential environmental hazards and increasing ...
Overproduction of Delta-Endotoxins by Sporeless Bacillusthuringiensis Mutants Obtained by Nitrous Acid Mutagenesis
(
Springer-Verlag
, 2011 , Article)
Asporogenic and oligosporogenic Bacillus thuringiensis mutants having the ability to overproduce insecticidal crystal protein were generated by using nitrous acid (50 mg/ml), as chemical mutagenic agent. Insecticidal crystal ...
Impact of synthesis conditions on meso- and macropore structures of resorcinol-formaldehyde xerogels
(
Springer
, 2011 , Article)
Xerogels were prepared by the sol-gel polymerization of resorcinol with formaldehyde at different conditions. The effects of different synthesis factors (namely, resorcinol-to-formaldehyde ratio, resorcinol-to-water ratio, ...
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
(
IEEE
, 2011 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ...
An efficient algorithm for instantaneous frequency estimation of nonstationary multicomponent signals in low SNR
(2011 , Article)
A method for components instantaneous frequency (IF) estimation of multicomponent signals in low signal-to-noise ratio (SNR) is proposed. The method combines a new proposed modification of a blind source separation (BSS) ...
