Compression garments and recovery from exercise: a meta-analysis
(Springer, 2017)Background Adequate recovery from exercise is essential to maintain performance throughout training and competition. While compression garments (CG) have been demonstrated to accelerate recovery, the literature is clouded ... -
Compromised bioavailable IGF-1 of black men relates favourably to ambulatory blood pressure: the SABPA study
(Elsevier, 2014)Objectives Insulin-like growth factor-1 (IGF-1) has potent endothelial-protective, anti-platelet and anti-thrombotic activities, and also exerts mitogenic and proliferatory actions on vascular smooth muscle cells. Conflicting ... -
Computational chemistry study of zirconium monomers in low acid concentration aqueous solutions
(IOP Publishing, 2018)Zirconium and hafnium have to be separated prior to their use in nuclear energy reactors. Therefore, a lot of research has been done on the solvent extraction of zirconium. However, most of this research involved screening ... -
Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator
(Elsevier, 2019)Energy-based fault detection and isolation (FDI) schemes show promise in terms of applicability to petrochemical industries and the broader process industries. Model-based FDI schemes offer pronounced advantages over more ... -
Computational method based on bernstein operational matrices for multi-order fractional differential equations
(Univ Nis, 2014)In this paper, the Bernstein operational matrices are used to obtain solutions of multi-order fractional differential equations. In this regard we present a theorem which can reduce the nonlinear fractional differential ... -
Computational method for non-linear singular boundary value problems
(SASIP, 2017)This paper presents a new numerical approach based on the Chebyshev polynomials of the first kind for solving a class of nonlinear singular boundary value problems arising in physiology. We apply the quasilinearization ... -
Computational methods for the determination of roundness of sedimentary particles
(Springer, 2006)A number of subjective and objective methods have been proposed to determine the roundness of rock particles, roundness being one of three properties describing the shape of a particle. Methods that make use of the Fourier ... -
Computational modelling and optimal control of Ebola virus disease with non-linear incidence rate
(IOP Publishing, 2017)The 2014 Ebola outbreak in West Africa has exposed the need to connect modellers and those with relevant data as pivotal to better understanding of how the disease spreads and quantifying the effects of possible interventions. ... -
A computational probe into the dissolution inhibitation effect of diazonaphthoquinone photoactive compounds on positive tone photosensitive polyimides
(ACS, 2017)Positive tone photosensitive polyimides ( p -PSPIs) composed of poly(amic acid) (PAA) and a diazonaph- thoquinone photoactive compound (DNQ PAC) have been greatly contributed to the progress of microelectronics. ... -
A computational study of pyrazinamide: Tautomerism, acid–base properties, micro–solvation effects and acid hydrolysis mechanism
(Elsevier, 2014)Pyrazinamide (PZA) is a prodrug substance utilised in the treatment of tuberculosis related to mycobacterium strains. The activities of this compound are said to occur in acidic medium where it is converted to the active ... -

A computer based assessment system for undergraduate electrical engineering modules
(SAIEEE, 2013)Good assessment is an essential component of good learning. Marking test and exam papers for large classes is however a time-consuming and repetitive task. This paper reports on the design and implementation of a computer ... -
Concentration contextualisation, temporal patterns and sources of hydrogen sulphide at a site on the South African Highveld
(Elsevier B.V., 2023)South Africa is one of the largest atmospheric sulphur emitting countries, but the contribution of H2S to this regional burden is not known. Also, no H2S source apportionment for South Africa have been undertaken, ... -
Concentrations and human health risk assessment of DDT and its metabolites in free-range and commercial chicken products from KwaZulu-Natal, South Africa
(Taylor & Francis, 2017)Organochlorine pesticides such as dichlorodiphenyltrichloroethane (DDT) have been used in agriculture and for disease control purposes over many decades. Reports suggest that DDT exposure may result in a number of adverse ... -
Concentrations and relative compositions of metallic elements differ between predatory squid and filter-feeding sardine from the Indian and South Atlantic oceans
(Elsevier, 2020)Although metallic elements occur naturally, they can occur or accumulate in organisms at levels toxic to the organism and/or their consumers. Concentrations of twenty-nine metallic elements in muscle tissue from sardine ... -
Concentrations of metallic elements in kidney, liver, and lung tissue of Indo-Pacific bottlenose dolphin Tursiops aduncus from coastal waters of Zanzibar, Tanzania
(Elsevier, 2017)Concentrations of metallic elements in kidney, liver and lung tissues of Indo-Pacific bottlenose dolphins Tursiops aduncus from coastal waters of Zanzibar were determined using inductively coupled plasma – optical emission ... -
Concentrations, distributions and critical level exceedance assessment of SO2, NO2 and O3 in South Africa
(Springer, 2010)South Africa has been identified as a source of industrial pollution that is significant at a global scale. This study was designed to provide quantitative information, by direct measurement, across northeastern South ... -
The concept "beneficial use" as a limitation of the right to use water
(2012)Die Witskrif oor 'n Nasionale Waterbeleid vir Suid-Afrika (1997) lui dat daar net 'n reg tot water vir die omgewing en basiese menslike behoeftes is, of ingevolge 'n magtiging om water te gebruik. Die skrywers van die ... -
