Reverend Frank Chikane represented shifts in Pentecostal beliefs and practices. He found it difficult to accept Christians who spoke in tongues on Sundays but oppressed others on Mondays. He found ...this hypocrisy to be the worst contradiction he had to contend with. He recognised the separation of spiritual, physical and social. He divided the church’s service to the world into three categories. The first is the ‘status quo’, that is the church, which ensures stability as long as the political system gives it space to proclaim the gospel. He called the second category ‘passage theology’. This refers to those who see themselves as passers-by in this troubled world, and therefore do not care about the politics of this world. The third category is the ‘involvement’ category. Of these three categories, Chikane chose the third. Based on the category of involvement, the author argues that Chikane is the epitome of shifts in Pentecostal beliefs and practices. To this end, the author will uncover and examine the core beliefs and practices of Pentecostalism, setting out the factors that gave rise to Chikane and also highlighting those that mark shifts in his spiritual agency. In the end, the author concludes that Chikane is indeed a catalyst for shifts in the practice of the African Pentecostal tradition today. The pattern of methodological approach followed in this article is the study of synthesised literature from libraries, particularly the sources that assisted me to gain insight into Chikane.Intradisciplinary and/or interdisciplinary implications: This article argues that Rev. Frank Chikane, through his ministry praxis, epitomises shifts in Pentecostal beliefs and practices. Although it is located in the field of missiology, it also has interdisciplinary implications for disciplines such as sociology, practical theology, and church history.
Chaplaincy in South Africa (SA) recently became an attractive ministry and research fields for both ministers and theologians, respectively, more especially since the dawn of democracy in 1994. The ...military chaplaincy has been flooded with applications and enquiries from ministers and leaders from religions other than Christianity who want to secure their space in the ministry to the SA armed forces. Individual churches are also joining the queue for enquiries. As SA is a multireligious nation, religions other than Christianity are also knocking at the door of the South African National Defence Force (SANDF), claiming their right to be accommodated. For this reason, it is important for churches, other religious organisations, leaders, ministers and theological institutions or faculties to have knowledge of this unique world and its context, as well as the ministry dynamics and challenges involved. This will assist them in order to prepare appropriately in terms of shaping the curricula and qualifications of their ministers for effective ministry to the armed forces with special reference to the SANDF. This article investigates the dynamics of the military chaplaincy in relation to historical developments along similar chaplaincies globally, the nature of its ministry to the SA armed forces and the challenges posed by the ministry context (SANDF environment), and finally, it crafts and proposes a suitable curriculum for a relevant and effective ministry in the SANDF and the world. Intradisciplinary and/or interdisciplinary implications: This article is located in the field of Missiology. However, it has interdisciplinary implications that affect disciplines such as Military Science, Sociology, Practical Theology and Church History, which all assist as building blocks towards a relevant ministry for the armed forces.
Highly crystalline poly-vinyl pyrrolidone (PVP) capped Sn nanocrystals with good size and shape uniformity was synthesized by a hydrothermal process. A highly sensitive amperometric biosensor for the ...detection of Bisphenol A (BPA) was developed by immobilizing Tyrosinase on to glassy carbon electrode (GCE) modified with Sn nanoparticles. The fabricated amperometric biosensor exhibited excellent electroactivity towards BPA oxidation catalysed by enzymatic reaction of tyrosinase together with good conductivity of Sn nanoparticles. The developed biosensor displayed linear range from 0.01 to 0.10 μmol L-1 and a detection limit (DL) of 1.8 nmol L-1 with a correlation coefficient of 0.989. Electrochemical impedance spectroscopy (EIS) obtained in buffer solution for Tyrosinase/SnNP/GCE had the lowest charge transfer resistance (Rct) value of 219 Ω, which indicated low charge transfer. There was an increase in Rct for Tyrosinase/GCE, SnNP/GCE and Bare GCE which was 316 Ω, 638 Ω and 598 Ω respectively. This indicated a strong resistance to charge transfer. It is reported for the first time the use of Sn nanoparticles modified on GCE and tyrosinase for detection of BPA.
Biological synthesis of zinc chromate mixed oxide nanoparticulate using natural leaf extracts of Hibiscus Rosa Sinensis. This is a simple, cost-effective and reproducible aqueous room temperature ...synthesis method to obtain spinel cubic phase ZnCr2O4 mixed oxide nanoparticles. X-ray diffraction (XRD) confirmed nanoparticles were crystalline with particle size estimated 14 nm for ZnCr2O4nanoparticles annealed at 700 °C, 26 nm at 500 °C, 56 nm at 200 °C and 70 nm at room temperature (RT). High resolution- transmission electron microscope (HR-TEM) and HR-scanning electron microscope (SEM) confirmed particles size of nanoparticles is around (fparticles) ∼14.5 ± 2 nm for HRTEM and 60–70 nm sized agglomerated cubic shaped particles for HRSEM. Fourier transform infrared spectrum (FTIR) was used for structural analysis. The band gaps calculated from UV–vis diffused reflectance (DR) are for ZnCr2O4mixed oxide nanoparticles at RT and annealed at 200 °C, 500 °C and 700 °C are 2.47 eV, 2.40 eV, 3.19 eV and 3.09 eV respectively. Fluorescence excitation was used to confirm band gaps of DR showing ZnCr2O4mixed oxide nanoparticles possess excellent photocatalytic activity.
We report on the optical and structural properties of plastic scintillators irradiated with neutron beams produced by the IBR-2 reactor of the Frank Laboratory of Neutron Physics in JINR, Dubna. Blue ...UPS-923A and green plastic scintillators were irradiated with neutron fluence ranging from 1013 to 1017 n/cm2. Discolouring in the plastic scintillators was observed after irradiation. The effects of radiation damage on the optical and structural properties of the samples were characterized by conducting light yield, light transmission, light fluorescence and Raman spectroscopy studies. The results showed that neutron radiation induced damage in the material. The disappearance of the Raman peak features in green scintillators at frequencies of 1165.8, 1574.7 and 1651.2 cm−1 revealed significant structural alterations due to neutron bombardment. Losses in fluorescence intensity, light yield and light transmission in the plastic scintillators were observed.
