    This study was carried out to determine the possibilities of using tobacco wastes in lightweight concrete production. The mixture combinations of materials such as tobacco waste, pumice, sand and cement were used to produce ...
  • Fernando, P. R.; Krishanthan, S. (2nd Conference of CIDA Restore Project, 2009)
    The water crisis is one of the most significant issues in Sri Lanka after the Tsunami inclusive of Batticaloa district. The people those who are living in the Batticaloa district especially in Tsunami affected areas are ...
  • Prinsloo, A. R. E.; Sheppard, C. J.; Fernando, P. R.; Madau, P. (59th Annual Conference of the South African Institute of Physics, 2013)
    Thin films and heterostructures of Cr and Cr alloys show fascinating properties that is not observed in the bulk material and research into their magnetic properties gives insight into dimensionality effects in these ...
  • Fernando, P. R.; Sheppard, C. J.; Prinsloo, A. R. E. (59th Annual Conference of the South African Institute of Physics, 2014)
    Abstract An investigation into the physical properties of Cr100-xIrx alloy single crystals, with x = 0.7, 1.5, 2.0 and 2.5, were previously used to determine the magnetic phase diagram of Cr100-xIrx alloy system around ...
  • Fernando, P. R.; Prinsloo, A. R. E.; Sheppard, C. J.; Lodya, L. (Journal of Applied Physics, 2014)
    Quantum criticality (QC) in spin-density-wave antiferromagnetic Cr and Cr alloy systems is a topic of current interest. In the present study, V was used as a tuning parameter to drive the Néel transition temperature (TN) ...
  • Fernando, P. R.; Sheppard, C. J.; Prinsloo, A. R. E. (Journal of Acta Physica Polonica A, 2016)
    The magnetic phase diagrams of Cr alloys with group-8 metals, such as Re and Ru, show interesting properties. These include quantum critical and superconducting behavior. In order to extend these investigations this ...
  • Fernando, P. R.; Karthika, U.; Parthipan, K.; Shandarabavan, T.; Ismail, R.; Jeeva, A (Advances in Recycling & Waste Management, 2017)
    Environmental pollution is big issue in the world, which is from the natural by-products. Some of these byproducts can be transformed into alternative energy source. Rice husk is the one of the natural by-product which ...
  • Horrocks, A. R.; Sitpalan, A.; Zhou, C.; Kandola, B. (Polymers, 2016)
    This work shows that halogen-free, flame retarded polyamide 6 (PA6), fabrics may be produced in which component fibres still have acceptable tensile properties and low levels (preferably ď10 wt %) of additives by ...
  • Dahiya, J. B.; Kandola, B.; Sitpalan, A; Horrocks., A. R. (Journal of Polymer Advance Technology, 2013)
    This paper extends the work of Lewin et al., which showed that high levels of flame retardancy could be conferred on polyamide 6 (PA6) in the presence of small concentrations of ammonium sulphamate (AS) and dipentaerythritol ...
  • Horrocks, A. R.; Kandola, B.; Milnes, G. J.; Sitpalan, A.; Hadimani, R. L. (Journal of Polymer Degradation and Stability, 2012)
    The effects of exposing to ultrasound compounded melts of polypropylene (PP) and polyamide 6 (PA6) formulations comprising nanoclays both alone and in the presence of other flame retardants are explored in terms of their ...
  • Peratheepan, P.; Strydom, A. M. (The European Conference, 2014)
    We have investigated the effects of magnetic Fe ion substitution in Ce(Ru1−xFex)2Al10 on the magnetic and transport properties, when the Kondo insulator CeRu2Al10 with anomalous antiferromagnetic order at TN = 27 K [1] ...
  • Khalyavin, D. D.; Hillier, A. D.; Adroja, D. T.; Strydom, A. M.; Manuel, P.; Chapon, L. C.; Peratheepan, P.; Night, K.; Deen, P.; Ritter, C.; Muro, Y.; Takabatake, T. (Physical Review, 2010)
    The low temperature state of CeRu2Al10 has been studied by neutron powder diffraction and muon spin relaxation (muSR). By combining both techniques, we prove that the transition occurring below T*~27K, which has been the ...
  • Maharaj, S. D.; Thirukkanesh, S (Mathematical Methods in the Applied Sciences, 2006)
    The condition for pressure isotropy, for spherically symmetric gravitational fields with charged and uncharged matter, is reduced to a recurrence equation with variable, rational coefficients. This difference equation is ...
  • Thirukkanesh, S; Maharaj, S. D. (Classical and Quantum Gravity, 2006)
    We study the Einstein-Maxwell system of equations in spherically symmetric gravitational fields for static interior spacetimes. The condition for pressure isotropy is reduced to a recurrence equation with variable, ...
  • Thirukkanesh, S; Maharaj, S. D. (Classical and Quantum Gravity, 2008)
    We consider the general situation of a compact relativistic body with anisotropic pressures in the presence of the electromagnetic field. The equation of state for the matter distribution is linear and may be applied to ...
  • Thirukkanesh, S; Maharaj, S. D. (PRAMANA- journal of Physics, 2008)
    We consider the linear equation of state for matter distributions that may be applied to strange stars with quark matter. In our general approach the compact relativistic body allows for anisotropic pressures in the ...
  • Maharaj, S. D.; Thirukkanesh, S. (Nonlinear Analysis- Real World Applications, 2009)
    We present new exact solutions for the Einstein-Maxwell system in static spherically symmetric interior spacetimes. For a particular form of the gravitational potentials and the electric field intensity, it is possible ...

    We study the gravitational behaviour of a spherically symmetric radiating star when the fluid particles are in geodesic motion. We transform the governing equation into a simpler form which allows for a general analytic ...
  • Thirukkanesh, S.; Maharaj, S. D. (Mathematical Methods in the Applied Sciences, 2009)
    A new class of exact solutions of the Einstein-Maxwell system is found in closed form. This is achieved by choosing a generalised form for one of the gravitational potentials and a particular form for the electric field ...
