Nuclear level densities and gamma-ray strength functions in Ta isotopes and nucleo-synthesis of ¹⁸ᴼTa
(University of the Western Cape, 2016)
Most stable and extremely low abundance neutron deficient nuclei with Z ≥ 34 are referred to as p-nuclei. Nearly all p-nuclei with A < 110 are most likely produced in the rp-process while almost all A > 110 are thought ...
The effects of environment on radio-loud AGN activity in Stripe 82
(University of the Western Cape, 2016)
We investigate the link between environment and radiative accretion efficiency using a sample of 8946 radio-loud AGN detected at 1 − 2 GHz in the SDSS Stripe 82 region. We quantify their environments using the surface-density ...
Hydrogen storage in Ti-based coatings and Ti6Al4V alloy
(University of the Western Cape, 2016)
Hydrogen has been regarded as an ideal energy carrier for future, it can be stored as a liquid in cryogenic tanks, a gas in high pressure cylinders and as solid in metal hydrides. Hydrogen storage in metal hydrides is of ...
In-situ measurements and calculation of radon gas concentration and exhalation from a tailings mine dump
(University of the Western Cape, 2013)
In Africa as well as in the world, South Africa plays an important role in the mining industry which dates back almost 120 years. Mining activities in South Africa mainly take place in Gauteng Province. Every year millions ...
Exploration of several radiation-based analytical techniques to investigate chlorides and chlorides effects within concrete
(2007)
In this study, the capabilities of Neutron Radiography (NRad) and -Tomography (NTomo), as well as X-ray Radiography (XRad) to investigate chlorides and chlorides corrosion effects within steel reinforced laboratory concrete ...
Probing the large-scale structure of the universe with correlation functions
(University of the Western Cape, 2014)
In this project we explore a new statistical package called KSTAT that computes the 2PCF and higher order correlation functions, such as the 3PCF, on BOSS, making use of high performance computing facilities to improve ...
Synthesis and characterisation of 114Cd targets
(2011)
To study nuclear reactions and nuclear structures, target materials are bombarded with high-energy particles. The target material can either be in a form of a metal film or gas. A target material designed to study certain ...
The impact of environment and mergers on the H I content of galaxies in hydrodynamic simulations
(University of the Western Cape, 2015)
We quantitatively examine the effects of merger and environment within a cosmological hydrodynamic simulation. We show that our simulation model broadly reproduces the observed scatter in H I at a given stellar mass as ...
Galaxy Evolution and Cosmology using Supercomputer Simulations by Daniel Cunnama
(University of the Western Cape, 2013)
Numerical simulations play a crucial role in testing current cosmological models of
the formation and evolution of the cosmic structure observed in the modern Universe.
Simulations of the collapse of both baryonic and ...
A study of the angular momentum content of early-type galaxies
(University of the Western Cape, 2019)
