Large artery stiffness is associated with marinobufagenin in young adults: the African-PREDICT study
(Wolters Kluwer, 2018)Objectives: The cardiotonic steroid, marinobufagenin (MBG), has been shown to play a physiological natriuretic role in response to salt intake. However, recent studies in clinical and animal models demonstrated possible ... -
Large artery stiffness is associated with salt intake in young healthy black but not white adults: the African-PREDICT study + Correction to article
(Springer, 2018)Purpose There is global consensus on the benefits of reducing excessive salt intake. Indeed, lower salt intake associates with reduced arterial stiffness, a well-established predictor of cardiovascular risk, in older ... -
Large nest building and high marble-burying: two compulsive-like phenotypes expressed by deer mice (Peromyscus maniculatus bairdii) and their unique response to serotoninergic and dopamine modulating intervention
(Elsevier, 2020)This study aimed to further dissect the deer mouse (Peromyscus maniculatus bairdii) model of compulsive-like behavior with respect to two persistent-like behavioral phenotypes viz. large nest building (LNB) and high ... -
Large sample behavior of the Bernstein copula estimator
(Elsevier, 2012)Bernstein polynomial estimators have been used as smooth estimators for density functions and distribution functions. The idea of using them for copula estimation has been given in Sancetta and Satchell (2004). In the ... -
Large sample properties of nonparametric copula estimators under bivariate censoring
(Taylor & Francis, 2016)A new nonparametric estimator is proposed for the copula function of a bivariate survival function for data subject to random right-censoring. We consider two censoring models: univariate and copula censoring. We show ... -
Large-scale design and testing of an improved fine coal dewatering system
(SAIMM, 2012)Fine coal (-500 μm) is notoriously difficult to dewater. It is not uncommon for a dewatered product to have a moisture content as high as 30 per cent after vacuum filtration. This poses several handling and financial ... -
Large-scale sugarcane farmers' knowledge and perceptions of Eldana saccharina Walker (Lepidoptera: Pyralidae), push–pull and integrated pest management
(Elsevier, 2014)A push–pull strategy for controlling Eldana saccharina Walker is being promoted as part of an area-wide integrated pest management (AW-IPM) programme in the South African sugar industry. Understanding farmers' perceptions ... -
The larva of Schismaderma carens (Smith, 1849) (Anura: Bufonidae): a redescription
(ISSCA, 2017)We describe the outer morphology of Schismaderma carens larvae in greater detail than previous studies, with special attention to the histology of the unusual head fold in this taxa. The oral cavity is described for the ... -
Laser assisted solid state reaction for the synthesis of ZnS and CdS nanoparticles from metal xanthate
(Elsevier, 2014)Nanoparticles of CdS and ZnS were produced by a nanosecond laser using zinc (II) and cadmium (II) complexes of ethyl xanthate. Laser pulses with a peak wavelength of 355 nm, pulse repetition rate of 10 Hz, and pulse ... -
Laser induced and controlled chemical reaction of carbon monoxide and hydrogen
(AIP, 2011)Bimolecular chemical reaction control of gaseous CO and H2 at room temperature and atmospheric pressure, without any catalyst, using shaped femtosecond laser pulses is presented. High intensity laser radiation applied to ... -
Laser induced H2 production employing Pt-TiO2 photocatalysts
(Elsevier, 2013)The photocatalytic production of hydrogen from water as well as from an aqueous methanol solution employing pre-treated TiO2 and various Pt-TiO2 photocatalysts was studied by using an Nd:YAG laser as irradiation source. ... -
Laser-assisted synthesis, and structural and thermal properties of ZnS nanoparticles stabilised in polyvinylpyrrolidone
(Elsevier, 2014)Zinc sulphide (ZnS) nanoparticles have been synthesised by a green approach involving laser irradiation of an aqueous solution of zinc acetate (Znac2) and sodium sulphide (Na2S·9H2O) or thioacetamide (TAA) in polyvinylpyrrolidone ... -
Late departures from paper-based to supported networked learning in South Africa: lessons learned
(IGI Global, 2018)Fragmented connectivity in South Africa is the dominant barrier for digitising initiatives. New insights surfaced when a university-based nursing programme introduced tablets within a supportive network learning environment. ... -
A late Pleistocene-Holocene multi-proxy record of climate variability in the Jazmurian playa, southeastern Iran
(Elsevier, 2019)We present a multi-proxy record from a 5-m long sediment core from the Jazmurian playa in southeastern Iran to provide insights into globally-recognized major climatic events since the Last Glacial Maximum (LGM). In ... -
LATE SUBMISSION: Moving to more than editing: standardised feedback in practice

Late-life effects of chronic methamphetamine exposure during puberty on behaviour and corticostriatal mono-amines in social isolation-reared rats
(Karger, 2014)Chronic methamphetamine (MA) abuse results in an acute psychosis indistinguishable from paranoid schizophrenia. However, less is known of the interaction between MA use and environmental insults, and how this contributes ... -
Lateral hydrological connectivity differentially affects the community characteristics of multiple groups of aquatic invertebrates in tropical wetland pans in South Africa
(Wiley, 2019)River–floodplain connectivity (i.e. lateral hydrological connectivity, LHC) can directly affect the community characteristics by promoting dispersal of organisms but can also have profound indirect effects by altering local ... -
Latitudinal gradients of galactic cosmic rays during the 2007 solar minimum
(IOP Publishing, 2008)Ulysses, launched in 1990 October in the maximum phase of solar cycle 22, completed its third out-of-ecliptic orbit in 2008 February. This provides a unique opportunity to study the propagation of cosmic rays over a wide ... -

Latyn en die opleiding van regstudente in Suid-Afrika: 'n nuwe relevansie
(Universiteit van Pretoria, 2010)Latin and the training of law students in South Africa: A new relevance This article reviews both the traditional arguments in favour of the retention of Latin as a compulsory university course for law students in South ...
