Galaxy correlations and the BAO in a void universe: structure formation as a test of the Copernican Principle

Author: February, Sean ; Clarkson, Chris ; Maartens, Roy Date: 19 A suggested solution to the dark energy problem is the void model, where accelerated expansion is replaced by Hubble-scale inhomogeneity. In these models, density perturbations grow on a radially inhomogeneous background. This large scale ... Read more
Bayesian inference for radio observations

Author: Lochner, Michelle ; Natarajan, Iniyan ; Zwart, Jonathan T L ; Smirnov, Oleg ; Bassett, Bruce A ; Oozeer, Nadeem ; Kunz, Martin Date: 25 New telescopes like the Square Kilometre Array (SKA) will push into a new sensitivity regime and expose systematics, such as direction-dependent effects, that could previously be ignored. Current methods for handling such systematics rely on ... Read more c b
Appearances can be deceptive: revealing a hidden viral infection with deep sequencing in a plant quarantine context

Author: Candresse, T ; Filloux, D ; Muhire, B ; Julian, C ; Galzi, S ; Fort, G ; Bernardo, P ; Daugrois, J-H ; Fernandez, E ; Martin, D P ; Varsani, A ; Roumagnac, P Date: 25 Comprehensive inventories of plant viral diversity are essential for effective quarantine and sanitation efforts. The safety of regulated plant material exchanges presently relies heavily on techniques such as PCR or nucleic acid hybridisation, ... Read more c b
ancGWAS: a post genome-wide association study method for interaction, pathway and ancestry analysis in homogeneous and admixed populations

Author: Chimusa, Emile R ; Mbiyavanga, Mamana ; Mazandu, Gaston K ; Mulder, Nicola J Date: 27 Despite numerous successful Genome-wide Association Studies (GWAS), detecting variants that have low disease risk still poses a challenge. GWAS may miss disease genes with weak genetic effects or strong epistatic effects due to the single-marker ... Read more
The effect of sulfide concentrate mineralogy and texture on Reactive Oxygen Species (ROS) generation

Author: Jones, Gavin C ; Becker, Megan ; van Hille, Robert P ; Harrison, Susan T L Date: ROS The generation of Reactive Oxygen Species (ROS), H2O2 and radical dotOH, has been observed from sulfide mineral containing particles in acidic solutions. The implications of this phenomenon, as a potential microbial stress-causing effect, ... Read more
The Emancipation of Transkei

Author: Schrire, Robert Date: Jan 1977 On 26 October 1976 the South African Government granted the Transkei, a 37,000 sq. kilometre territory on the south-east coast of the Cape Province, independence. With the exception of South Africa, no state has recognized Transkei and, indeed, ... Read more
Intra-osseous synovial sarcoma.

Author: Rose, A G ; Uys, C J ; Brawn, E Date: 1982 Intra-osseous synovial sarcoma is very rare and its mode of origin is conjectural. Our patient's tumour was situated within the lower femur. The sited of origin of the few intra-osseous synovial sarcomas so far documented may support the ... Read more
Eighteenth Century Cape Society and its Historiography: Culture, Race, and Class

Author: Giliomee, Hermann Date: 1983 The revisionist literature of the 1970s approached social stratification in South Africa with the insistence that proper 'weighting' of the race and class factors should occur. Arguing that class and not racial consciousness was the key ... Read more
Diamphotoxin: the arrow poison of the Kung bushmen

Author: DE LA HARPE, J ; REICH, E ; REICH, K ; DOWDLE, E Date: 1983 Purification de la diamphotoxine et étude de ses caractéristiques pharmacologiques et biochimiques. Read more
Interaction of nucleotides and cations with the (Ca2+, Mg2+)-ATPase of sarcoplasmic reticulum as determined by fluorescence changes of bound 1-anilino-8-naphthalenesulfonate

Author: Arav, R ; Aderem, A A ; Berman, M C Date: 1983 The changes in fluorescence of 1-anilino-8-naphthalenesulfonate (ANS-) have been used to determine binding of ligands to the (Ca2+, Mg2+)-ATPase of sarcoplasmic reticulum vesicles, isolated from rabbit skeletal muscle. ANS- binds to sarcoplasmic ... Read more
Constitutional change and the issue of reform: A Review of the Buthelezi Commission and President's Council Constitutional Reports

Author: Schrire, Robert Date: Jan 1983 One of the recent growth industries in our political life is in the field of constitutional proposals. From the government side we have had among others the Theron Commission, the Parliamentary Select Committee on the Constitution, and three ... Read more
Strange particle production in pp and pN reactions

Author: Greiner, Walter ; Koch, Peter ; Rafelski, Johann Date: 1984 A statistical model of particle production valid for a wide range of Feynman x is developed and applied to describe strange particle production in hadronic collisions. Predictions of relative abundances of multiply strange hadrons are made ... Read more
The rhetoric and reality of local government reform

Author: Cameron, Robert Date: 1986 N. Dewar, in his article; 'Municipal Government under the New South African Constitution: Who Gets What, Where, Who Decides, and Who Decides Who Decides?' Social Dynamics, Vol. 11(2), argues that the new local government legislation could ... Read more
DNA hypermethylation in sodium butyrate-treated WI-38 fibroblasts

Author: PARKER, M Iqbal ; de Haa, Judy B ; Gevers, Wieland Date: 1986 Sodium butyrate is very often used to alter gene expression in cultured cells. In this study, we examined the effects of this compound on various cellular events in WI-38 human embryonic lung fibroblasts in culture. During a 16-20-h treatment ... Read more
Attitudes to adverse drug reactions and their reporting among medical practitioners

Author: Robins, A H ; Weir, M ; Biersteker, E M Date: 1987 The adverse drug reaction (ADR) reporting rate within the medical profession is exceptionally low, and doctors' approaches and attitudes to ADRs were explored through personal structured interviews. The total sample comprised 104 doctors in ... Read more
Redistribution of strangeness between quark-gluon plasma and hadronic gas

Author: Rafelski, J Date: 1987 In a baryon-rich hadronic gas s-quarks, unlike antistrange quarks, can be found in baryonic degrees of freedom. This abundance asymmetry induces an associated asymmetry in the otherwise symmetric quark-gluon plasma section of the fireball ... Read more
Modelling techniques for biological reaction systems: 1 Mathematical description and model representation

Author: Billing, Alison Emslie ; Dold, Peter Lorimer Date: 1988 This paper is the first in a series of three which deals with modelling and numeric techniques for biological reaction systems. A matrix for ma rov1des a usef\11. method for model presentation. The matrix ensures clarity as to the ... Read more
Causation and the concomitant issue of apportionment with reference to gross income in South African income- tax law

Author: Emslie, Trevor ; Jooste, Richard Date: 1989 The objective of this article is twofold: first, to set out the correct role, in our view, of the notion of causation in the application of two elements of the definition of gross income-the characterization of an amount as being from a source ...
