Interdisciplinarity in Action


Lunchtime learning webinar on


The  Intersection between Science and Visual Arts


In this webinar, Prof Willem Boshoff and Prof Louis Scott, both from the University of the Free State, will discuss the intersection between science and the visual arts. The webinar will explore how new levels of understanding may emerge when seemingly unrelated fields of interest intersect, supported by the ideas we may find in the endless diversity of nature.

This webinar is part of a series of three webinars on Interdisciplinarity presented from November to December 2020 via Microsoft Teams for a duration of 45 minutes each. The webinar topics in the series explore the intersection between Neuroscience and Music, between Science and Entrepreneurship, and between Science and Visual Arts. 
 
Date: Tuesday 8 December 2020
Topic: The intersection between science and visual arts 
Time: 13:00-13:45 (SAST)
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 7 December 2020 
Platform: Microsoft Teams

Introduction and welcome
 
Prof Corli Witthuhn – Vice-Rector: Research at the University of the Free State 

Presenters

Prof Willem Boshoff
Willem Boshoff is a Senior Professor in Fine Arts at the University of the Free State. As a conceptual artist, he engages primarily with language. Notably, his works have included the writing of several themed dictionaries, most often made accessible to a broad audience in the form of large art installations. His broad interdisciplinary interests, including the fields of botany, music, and lexicography, have over the years led to the development of a digital research archive, which he recently donated to the University of the Free State.  Prof Boshoff’s work is exhibited extensively, both locally and abroad, and has been included in major private collections and museums. Recently, he became the first South African artist to be awarded an A2 rating by the National Research Foundation (NRF). 

Prof Louis Scott
Prof Louis Scott is a retired professor and mentor in the Department of Plant Sciences at the UFS, with an interest in visual arts. He studies fossil pollen in natural lake, cave, swamp, and fossil dung deposits. He attempts to reconstruct our heritage associated with African prehistory through environmental history, including natural long-term processes of change. Prof Scott is widely published in this field, serves on the editorial boards of international journals, and has a B-rating with the National Research Foundation.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
