Stable atmospheric environments and near perfect weather conditions were the main reasons for the establishment of the Boyden Observatory a few kilometres outside Bloemfontein. This astronomical research observatory and science education centre is managed by the Department of Physics at the University of the Free State (UFS).

With the newly acquired astronomical spectrograph for the Boyden Observatory 1,5-m telescope, scientists will be able to gain visual access to both the Northern and Southern Hemisphere skies.

Collaboration with expert in stellar spectroscopy 

The spectrograph, mainly developed and built by Dr Richard Gray, will be used collaboratively for astronomical research by the UFS and the Appalachian State University (ASU) in North Carolina, where Dr Gray is based. 

Dr Gray is a world-renowned expert in stellar spectroscopy and leading author of one of the most influential textbooks on stellar spectroscopy, Stellar Spectral Classification, with co-author Christopher J Corbally.

Dr Gray recently received a Fulbright Scholarship from the Fulbright Foundation to spend a full year in the UFS Department of Physics, where he will lecture several Astronomy classes and do research in collaboration with personnel of the UFS Astrophysics Research Group. He will also lead the assembly of the instrument over the next few weeks, working with personnel and students in the Department of Physics as well as the UFS Instrumentation Division.

According to Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, some components of the instrument have been developed and constructed by the university’s Instrumentation Division, with key components purchased from funding by the Directorate: Research Development at the UFS.

Unique capability in infrastructure 

“The availability of a sophisticated instrument of this nature on the 1,5-m telescope will place the UFS Astrophysics Group in an elite bracket in terms of the available infrastructure for astronomical research,” said Prof Meintjes.

He explained: “The combined polarimetric-spectroscopic capability in one single instrument is unique. Combined with the fact that it is hosted on a research instrument that is utilised and maintained exclusively by the UFS Astronomy Group in the Department of Physics, gives this group a competitive edge in relation to most international astronomy groups.” 

The instrument is valued at close to R1,5 million.

According to Prof Meintjes, the instrument will be mounted at the backend of the UFS Boyden 1,5-m telescope and will allow them to do simultaneous polarimetry and spectroscopy of astronomical sources. “This is vital for the research we are working on,” he said.

International collaboration and student development

The instrument also brings with it the possibility of forging international collaborations for research as well as student development. “This can advance the stature of the UFS as an internationally respected research-led tertiary institution,” said Prof Meintjes. 

The possibility of making the UFS Boyden 1,5-m telescope completely remote-controlled, is being investigated. “This will serve the observational needs of researchers from both the UFS and the ASU, with researchers at ASU able to access the telescope for their own in-house research programmes. The availability of such an instrument on the UFS 1,5-m telescope also opens up the possibility to accommodate visiting researchers from ASU or elsewhere in the world at Boyden,” said Prof Meintjes.

Fighting the tuberculosis battle as a collective
2015-09-28



The team hard at work making South Africa a
healthier place

Tuberculosis (TB) is second only to HIV/AIDS as the greatest killer worldwide due to a single infectious agent. More than 95% of TB deaths occur in low- and middle-income countries. Despite being more prevalent among men than women, TB remains one of the top five causes of death amongst women between the ages of 15 and 44 years. While everyone is at risk for contracting TB, those most at risk include children under the age of five and the elderly. In addition, research indicates that individuals with compromised immune systems, household contacts with pulmonary TB patients, and healthcare workers are also at increased risk for contracting TB.

According to the Deputy Director of the Centre for Health Systems Research and Development (CHSR&D) at the UFS, Dr Michelle Engelbrecht, research has found that healthcare workers may be three times more likely to be infected by TB than the general population.

The unsettling fact

“Research done in health facilities in South Africa has found that nurses do not often participate in basic prevention acts, such as opening windows and wearing respirators when attending to infectious TB patients,” she explained. 

In response to this concern, CHSR&D, which operates within the Faculty of Humanities at the the University of the Free State (UFS) Bloemfontein Campus has developed a research project to investigate TB prevention and infection control in primary healthcare facilities and households in Mangaung Metropolitan.

Action to counter the statistics

A team of four researchers and eight field workers from CHSR&D are in the process of gathering baseline data from the 41 primary healthcare facilities in Mangaung. The baseline comprises a facility assessment conducted with the TB nurse, and observations at each of the facilities. Individual interviews are also conducted with community caregivers, as well as TB and general patients. Self-administered questionnaires on knowledge, attitudes, and practices about TB infection control are completed by all nurses and facility-based community caregivers.

Healthcare workers are the main focus of this research, given their increased risk of acquiring TB in healthcare settings. At clinics, interventions will be developed to improve infection control practices by both healthcare workers and patients. TB patients’ households are also visited to screen household contacts for TB. Those found to have symptoms suggesting TB infection are referred to the clinics for further assessment and treatment.

The findings of this study will serve to inform the development of an intervention to address TB prevention and infection control in primary healthcare facilities. Further funding will be sought to implement and evaluate the intervention.

Curbing future infections and subsequent deaths as a result of TB is the priority for the UFS. The cooperation and collaboration of the community, government, and sponsors will ensure that this project is a success, hence prolonging life expectancy.
