Synthesis and characterisation of a polysulfone-polyvinyl alcohol hydrogelic material
(ESG, 2016)
Hydrogels are flexible materials that have found a niche in membrane science owing to their ability to
absorb water without dissolving. The synthesis of polyvinyl alcohol-polysulfone hydrogel in the
presence of N-hydroxy ...
Dark energy homogeneity in general relativity: Are we applying it correctly?
(Springer, 2016)
Thus far, there does not appear to be an agreed (or adequate) definition of
homogeneous dark energy (DE). This paper seeks to define a valid, adequate homogeneity
condition for DE. Firstly, it is shown that as long as ...
Challenges in translating RL Peteni’s Xhosa novel Kwazidenge into Afrikaans
(South African Journal of African Languages, 2016-06-28)
In a multilingual country like South Africa, translation from one of the official languages into another plays a major role, particularly in the public sector or the public domain. The purpose is to inform ...
Use of a rat ex-vivo testis culture method to assess toxicity of select known male reproductive toxicants
(Elsevier, 2016)
Due to the complex physiology of the testes, in vitro models have been largely unsuccessful at modeling testicular toxicity in vivo. We conducted a pilot study to evaluate the utility of the Durand ex vivo rat seminiferous ...
Autoimmune progesterone dermatitis: Case report with history of urticaria, petechiae and palpable pinpoint purpura triggered by medical abortion
(South African Medical Association, 2016)
Autoimmune progesterone dermatitis (APD) is a rare autoimmune response to raised endogenous progesterone levels that occur during the
luteal phase of the menstrual cycle. Cutaneous, mucosal lesions and other systemic ...
Computational characterization of iron metabolism in the tsetse disease vector, glossina morsitans: Ire stem-loops
(BMC, 2016)
Iron metabolism and regulation is an indispensable part of species survival, most importantly for
blood feeding insects. Iron regulatory proteins are central regulators of iron homeostasis, whose binding to iron
response ...
A simple, high-throughput modeling approach reveals insights into the mechanism of gametophytic self-incompatibility
(Nature Research, 2016)
Specificity in the GSI response results from the S-haplotype-specific molecular interaction of S-locus
F-box (SLF/SFB) and SRNase proteins in the self-incompatibility locus (S-locus). The answer to the
question of how ...
On the time delay between ultra-relativistic particles
(Elsevier, 2016)
The time delay between the receptions of ultra-relativistic particles emitted simultaneously is a useful observable for both fundamental physics and cosmology. The expression of the delay when the particles travel through ...
Will a rising sea sink some estuarine wetland ecosystems?
(Elsevier, 2016)
Sea-level rise associated with climate change presents a major challenge to plant diversity and ecosystem service
provision in coastal wetlands. In this study, we investigate the effect of sea-level rise on benthos, ...
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 ...
