Low-Cost feedstock conversion to biodiesel via ultrasound technology
(MDPI, 2009)
Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable ...
Is there evolution in the infrared Tully–Fisher relation? Comparing two linear regressions
(Oxford University Press, 2009)
In a recent paper, Puech and co-workers compared K-band Tully–Fisher relations derived
for nearby and distant galaxies, respectively. They concluded that the two relations differ,
and deduced that there is evolution in ...
A novel cell-based binding assay system reconstituting interaction between SARS-CoV S protein and its cellular receptor
(Elsevier, 2005)
Severe acute respiratory syndrome (SARS), a life-threatening disease, is caused by the newly identified virus SARS coronavirus (SARSCoV).
In order to study the spike (S) protein of this highly contagious virus, we established ...
Identification and characterization of the Trichoplusia ni Single Capsid Nuclear Polyhedrosis Virus p10 gene
(Springer Verlag, 2000)
The p10 gene was identified and characterized from the Trichoplusia ni single capsid nuclear
polyhedrosis virus (TniSNPV). The p10 open reading frame (ORF) sequence was identified following sequencing
of the ends of the ...
Groundwater management issues in Southern Africa – An IWRM perspective
(Water Research Commission, 2008)
In contrast to its strategic role as essential resource to help achieve community development and poverty alleviation in the
Southern African Development Community (SADC), groundwater has remained a poorly understood and ...
Photometry of the magnetic white dwarf SDSS 121209.31+013627.7
(Oxford University Press, 2006)
The results of 27 h of time series photometry of SDSS 121209.31+013627.7 are presented.
The binary period established from spectroscopy is confirmed and refined to 0.061 412 d
(88.43 min). The photometric variations are ...
The analysis of irregularly observed stochastic astronomical time-series – I. Basics of linear stochastic differential equations
(Oxford University Press, 2005)
The theory of low-order linear stochastic differential equations is reviewed. Solutions to these
equations give the continuous time analogues of discrete time autoregressive time-series. Explicit
forms for the power ...
A re-assessment of the nearest neighbour alignment of the X-ray isophotes of galaxy clusters
(Oxford University Press, 2006)
Alignment is defined as the tendency of the distribution of pointing angles between the major
axes of clusters and their nearest neighbours to be more concentrated towards small values
for small nearest neighbour distances, ...
On the upper limit on stellar masses in the Large Magellanic Cloud cluster R136
(Oxford University Press, 2006)
A truncated power-law distribution is fitted to the 29 largest stellar masses known in R136.
Two different statistical techniques are used, with comparable results. An upper limit to the
mass distribution of the order ...
JHKs time-series observations of a few ultracool dwarfs
(Oxford University Press, 2005)
The M8.5 object SSSPM J0109−5101 has recently been shown to be both a periodic and a
flaring variable, based on optical observations in the extreme red. More than 16 h of monitoring
in the near-infrared (NIR) reported ...
