Reconstruction of dark energy and expansion dynamics using Gaussian processes
(IOP Publishing, 2012)
An important issue in cosmology is reconstructing the effective dark energy equation
of state directly from observations. With few physically motivated models, future dark
energy studies cannot only be based on constraining ...
The potential of leucosidea sericea against propionibacterium acnes
(Elsevier, 2014)
The present study reports on the potential of Leucosidea sericea addressing acne vulgaris. Four known compounds namely phytol acetate, triacontanol, phytol and alpha kosin and one new compound namely, (E)-3,7,11,15-tetra ...
Understanding the creek dynamics and environmental characteristics that determine the distribution of mangrove and salt marsh communities at Nahoon Estuary
(Elsevier, 2016)
The southern distributional limit for mangroves on the east coast of Africa is thought to be at the planted
mangrove forest at Nahoon Estuary (33° S) in the Eastern Cape, South Africa. This study investigated the influence
of ...
Identification and characterization of a heat-inducible Hsp70 gene from Sorghum bicolor which confers tolerance to thermal stress
(Springer, 2015)
This study describes the first detailed molecular
characterization of the heat shock protein 70 (Hsp70) gene
from Sorghum bicolor, MN1618 designated as SbHsp70-1.
The full-length cDNA of SbHsp70-1 consists of 2524 bp ...
Nonlinear galactic dynamos and the magnetic pitch angle
(American Astronomical Society, 2015)
Pitch angles p of the large-scale magnetic fields B of spiral galaxies have previously been inferred from
observations to be systematically larger in magnitude than predicted by standard mean-field dynamo theory. ...
Antibacterial and anti-inflammatory effects of Syzygium jambos L. (Alston) and isolated compounds on acne vulgaris
(BioMed Central, 2013)
Acne vulgaris is a chronic skin disorder leading to inflammation as a result of the production of
reactive oxygen species due to the active involvement of Propionibacterium acnes (P. acnes) in the infection site of
the ...
Unique aliphatic amidase from a psychrotrophic and haloalkaliphilic nesterenkonia isolate
(American Society for Microbiology, 2011)
Nesterenkonia strain AN1 was isolated from a screening program for nitrile- and amide-hydrolyzing microorganisms in Antarctic desert soil samples. Strain AN1 showed significant 16S rRNA sequence identity to known members ...
Maths4Stats: Opleiding vir onderwysers
(AOSIS, 2013)
Maths4Stats: Educating teachers. The inadequate nature of the education infrastructure
in South Africa has led to poor academic performance at public schools. Problems within
schools such as under-qualified teachers and ...
Statistical gamma-ray decay studies at iThemba LABS
(EDP Sciences, 2017)
Abstract. A program to study the γ -ray decay from the region of high-level density has been established
at iThemba LABS, where a high-resolution gamma-ray detector array is used in conjunction with silicon
particle-telescopes. ...
Relativistic mean field formulation of clustering in heavy nuclei
(IOP, 2010)
Very little is known about clustering in heavy nuclei and in particular the
interaction between the correlated cluster nucleons and remaining core nucleons. Currently
the phenomenological Saxon-Woods plus cubic Saxon-Woods ...
