- Description: This treatise was born out of an ecological concern for the decline in the bee population witnessed by beekeepers since the late 1990’s. This sudden decline in the bee population has a direct impact on one third of the food we consume which leads to a decrease in food production and an unbalanced ecosystem. The distinct biomes in the Eastern Cape of farming and nature reserves, provides a foundation for an investigation into an architectural intervention of a remedial nature to help the bees breed and restore the natural pollination services. A qualitative research approach has been conducted to focus on the relationship between man and nature and how man-made structures can successfully integrate into the natural process of bee breeding and honey production. This provided a platform to develop an architectural intervention that responded to the ecological issues of the dying bee population. This Paper unpacks the issues which contribute to the bee population in decline and the different types of systems and stages that are required in beekeeping and its by-products. The findings lead to the process of developing an appropriate brief and arriving at a design response which will allow sustainable ways of achieving radical increases in resource efficiency. As a result, the breeding process will provide natural product as well as educate the public and farmers of the region, about the bees. A site specific and factory archetype of architecture will be investigated to facilitate the transformation of site into a bee friendly environment, which will contribute to the rehabilitation of the pollination process in the Eastern Cape.

- Description: Tuberculosis, and more specifically drug resistant tuberculosis, is a growing epidemic in South Africa. Yet many of the existing specialised tuberculosis facilities have been designed in a way that do not incorporate biophillic elements necessary to create a healing environment with spaces conducive to the wellness of its users. This treatise responds to these issues through the design of a hospital that utilises biophillic principles with highly inclusive spaces providing a dignified sense of place for drug-resistant tuberculosis patients where the architecture offers more than a functional space. It induces healing.

- Description: Out of a total of 236 active correctional centres across South Africa, only 5.5% of these cater to the needs of juvenile offenders, and none of these are located within the immediate Port Elizabeth area. This means that in their already fragile state, children from Port Elizabeth and the immediate surrounding areas are sent away from their families and support base to serve their sentence. Therefore, a need for a Juvenile Detention Centre within the Port Elizabeth area was realized. In this treatise an investigative study of existing Juvenile Detention Centres was carried out to which an understanding of the building typology, nature of the site and technical requirements was formulated. The site selected in Schauderville conforms to the site selection criteria established, and enhances the link to Nerina One Stop Child Justice Centre. The primary focus of the study was to design a building to provide secure residential care for juvenile offenders, offering a range of programmes to assist their rehabilitation back into society. The outcome, is presented as a set of architectural drawings and a model(s).

- Description: This treatise is the result of an initial interest in the concept of ‘terrain vague’, the phenomenon of disconnected spaces that are internal to the city yet exist outside the effective and functioning networks of the urban system (Sola-Morales 1995, 120). The notion of terrain vague informs the theoretical preoccupation of this study and sets the basis on which the contextual and programmatic concerns are considered and explored. The harbour precinct of Port Elizabeth was selected as the focus area for the study, in which the characteristics of the terrain vague were uncovered through a series of maps, diagrams and photographs. The role of the cemetery as a type of terrain vague in the urban fabric is simultanelously investigated. The study refers to Richard Weller’s interpretation of the nature of the contemporary city and principles of landscape urbanism as a basis for developing ways of approaching the city and it’s spaces of terrain vague.Through this, the study is situated predominantly in the ecological discourse. The use of precedant studies as a means of exploring the application of the theoretical principles discussed in this study is key to providing the reader with a contextual understanding and clarity. The architectural intervention proposes a memorial park in the harbour precinct. This aims to generate a spatial awakening of the terrian vague. By reclaiming the denatured landscape (oil tank farm) and re-scripting it as a culturally significant area that is re-integrated into the public realm, the opportunity to rehabilitate the ecological flows of the city is realised. The design of a promatorium complex within the proposed memorial Park aims to re-introduce the funerary landscape into the city and in doing so challenges the threat of cemetries remaining as spaces of terrain vague. The promatorium complex is seen as a facility that supports the functions of the memorial park as a commemorative landscape in the 21st century. In all this intervention aims to transform a disregarded wasteland into an operational landscape. The aim is to enhance the ecological systems of the city and by extension to reconcile the interface between man and nature.

The existing public buildings which should be major structuring elements are dispersed within the built environment which results in a lack of a structural ordering system. The issue identified above create an opportunity for architecture to serve as a catalyst towards creating positive urban environments which can then build a sense of dignity and pride for the community.

- Description: The purpose of this document is to look into the concept of Transport Orientated Development through the design of a Passenger Transit Intermodal in East London in the Eastern Cape, South Africa. This concept of urban design and development is one which the focus of mixed use development is centered on maximizing access to public transportation. This paper also looks into the discourse around public transportation as an important tool in the integration of cities in post-apartheid South Africa. The aim of this paper is to engage with the architectural challenges of designing an intermodal transportation hub. This paper also aims and engaging the issue of public transportation in a democratic South Africa and its integration in all its forms, which previously may have served only particular demographics of the country i.e. the mini-bus taxi as a solution to the problem of transportation in the townships and its infiltration into the city environment. Through literature, scientific and peer reviewed journals, desktop research, photographs, informal interviews such as analysis, precedence and other qualitative studies, it will be demonstrated, through interpretation of the that there is a need for the integration of public transportation and this can be best achieved through the design of an intermodal passenger transport facility. The finding of this paper is that there is a need to integrate the public transportation sectors in South Africa. The taxi industry, for example, has developed independently of the other means of public transportation i.e. the train and bus systems; and has led to a public transport system that often duplicates or triplicates its functions. In conclusion, public transportation, i.e. trains, buses and minibus axis provide an essential service to the public, especially low income groups as they service a greater portion of this population, offering several benefits such as accessibility ,cost, reduced travel time, etc. Through the design of a transit intermodal, the integration of all forms of public transportation will be shown as being an essential cornerstone to the development of more integrated South African cities in a democratic dispensation.

- Description: This treatise addresses the current lack in concern for acknowledging and preserving the memories and historical elements of a once thriving place: South End, Port Elizabeth (fig. 11, p. 20). The Group Areas Act of 19501 (Y. Agherdien, A. C George, S. Hendricks, 1997) resulted in expropriation of land and the demolision of buildings and roads which started to take place in South End during the 1970’s, forcefully removing the residents from their home neighbourhood and home. The treatise focuses on the traces of what is left of South End (fig. 02, in red) and how these elements can be acknowledged and preserved for the future generations. Theories on the discourse of memory, specifically collective memory, are investigated to establish an understanding on different methods to capture, record and preserve these traces and memories of South End. This investigation will be followed by principle explorations to establish how these theories can be implemented and manifested in the historical landscape. It is proposed to design an archive next to St. Peter’s Church, above St. Mary’s Cemetery in South End and a memorial park on the “triangular site” across from the cemetery, addressing the existing conditions of the landscape and the memories of the ex-residents of South End (figs. 16-18, p. 24). The archive will consist of a conventional archive (static element) housing the maps and documentation related to the city of Port Elizabeth, and an oral archive (dynamic element) consisting of a recording studio that collects and records the stories of the ex-residents of South End, constantly changing and adding to the archive. The memorial park will resemble a “living archive” which constantly changes and re-evokes the memories of the original inhabitants of South End. The proposed project is intended to act as an educative catalyst to the visitors, citizens of Nelson Mandela Bay and the future generations.

- Description: Humans have an innate psychological and emotional affinity to the sacred natural world, however with increasing urbanization nature and the natural world is under threat, presenting a situation which is likely to have physical and emotional consequences for society. This treatise grapples with issues pertaining to the interface between man and nature and its relation to the sacred. It examines how the architecture concerning a building type, the Sufi Lodge, found within traditional Islamic architecture can be translated into the 21st century to strengthen the sense of culture, meaning and spirituality for the Islamic Sufi community that exists within South Africa. The challenge is firmly rooted in notions of place making as well as this interface between man and nature. Emile Durkheim’s dichotomy of sacred and profane is used as a starting point to build a discussion around issues that come with the creation of sacred place in the artificial and natural. Architectures role in this, in its nature as a mediator between realms, is analysed, particularly focussing on Thomas Barrie’s principles of sacred place creation. These principles are then overlaid with the specific Islamic formal belief system to create an approach which embraces community, culture and the sensitivities of making in a natural landscape.In all this treatise seeks to understand the principles in order to develop a proposal for an Islamic Sufi Lodge for the Islamic Sufi community in Cape Town South Africa. This facility looks to serve as a vessel for interactions within a greater social network creating a space for pilgrims and residents, allowing for ritual gathering and learning as well as providing a liminal place for solitude and deep spiritual connection to nature.

- Description: The adoption of a critical spatial perspective is imperative, if social justice is to be performed in urban environments, according the urban theorist Edward Soja. From this perspective of a socio-spatial dialectic, understood using Lefebvre’s ideas around the social production of space and the right to the city, the current spatial conditions of Port Elizabeth are seen as perpetuating past constructions of inequity. In these constructions of inequity large, systematically oppressed groups of the public are forced to traverse across segregating urban barriers to access the opportunity and advantages of living in an urban system. This condition continues to disadvantage those it was historically set up to undermine, on economic and social terms. This condition subverts these urban nomads, who are those forced into transience to access urban opportunity. Korsten is investigated as a key transition space in the Port Elizabeth area, straddling the impoverished north and wealthy south, as one of the key spaces where the urban nomad moves through to access better resourced parts of the city. The space of Korsten is understood to be a key domain for the urban nomad in Port Elizabeth and is thereby an appropriate place for intervention to intensify the city and improve urban quality, thus dignifying and enriching the lives of citizens and improving equity in the city. The notion of opportunity is focused on as the catalytic vehicle for urban quality to be improved, ultimately resulting in the design of Korsten as an urban resources centre with new educational and economic resources as a central structuring element in a re-scripted field of resources. The architectural design is produced within the paradigm of field conditions. This results in a design product which integrates as a part of a field condition of public resources in Korsten. A qualitative methodology is adopted within the critical research paradigm and will use methods of desktop surveys, literature reviews and participant observation to collect data.

- Description: The ideology of society can be argued to the main generation of the spatal coding and structuring of the city. it is thus spatal and physical remnants of past ideologies that form the ideological legacy as a product. The product with determines the lived experience of society in the city today. this study examines the nature of space as a socio-spatial construct of the ideological legacy of society and how in turn this legacy affects the physical and spatal manifestation of the lived experience of a society with a contrasting ideology, within the city of current Johannesburg.

- Description: The value of waste as a resource, diverting waste from landfills and the need for a circular economy, was emphasised at the South African and European Colloquium on recycling hosted by PETCO, the polyethylene terephthalate company (Godfrey, 2013, p. 17). In South Africa, the recycling industry is seen as a means to provide income and skills development, and to create sustainable livelihoods. Yet, the country remains deeply entrenched in landfilling (Godfrey, 2013, p. 19). According to Zhang, Huang, Yin and Gong (2015, p. 9475) “understanding the factors that affect residents’ waste separation behaviours helps in constructing effective environmental campaigns for the community”. The focus of a waste management system should be to motivate and convince the consumer to dispose of their waste in a sustainable manner. The waste separation decision is complex and can be explained by the theory of planned behaviour and theory of reasoned action (Nguyen, Nguyen, Lobo & Dao, 2017, p. 2). The aim of this study is to identify and evaluate the factors that influence the waste separation behaviour of households in the Uitenhage area. In order to achieve this aim, secondary research (literature review) and primary research (empirical study) were conducted. The study has shown that if the residents are presented with free containers and have access to a collection service which facilitates the flow of the recyclables from the point of consumption to the point of sustainable disposal and conversion, it could motivate them to separate the waste. The only variable that was found significant in relation to household waste separation behaviour was motivation. The respondents are motivated to separate their household waste; yet, they do not separate it. The frequency distribution analysis reported that the sample was not experienced waste separators, where less than half of the sample was engaged in some waste separation activities. Yet, the respondents had a positive attitude towards the importance of waste separation and disagreed that waste separation is inconvenient. The majority of the respondents agreed that they have control over their behaviour and that the decision to separate their waste is within their control, but yet they do not separate their waste. The respondents agreed that they have the knowledge of what and how to separate waste, however, disagreed that they know where to take their separated waste. Interestingly, the respondents agreed that waste separation is The determinants of waste separation behaviour in Uitenhage, South Africa part of their moral norms; yet, they do not consider family and friends, including the municipality, to exert social pressure on them to separate their household waste. It is recommended that the municipality investigates the requirements for implementing a waste management scheme which provides containers for free and collects separated waste from households. Entrepreneurs can also play a pivotal role in bridging the gap in the waste management supply chain by establishing buy-back centres and sustainable recycling depots to facilitate the collection of separated waste for recycling. These collection services, buy-back centres and recycling depots present business opportunities and job creation potential, which will drive the economic growth in the Nelson Mandela Bay area.

- Description: The HIV integrase enzyme is a validated drug target. However, its potential has remained largely unexploited until recently due to lack of structural and mechanistic information. Its catalytic core domain (CCD) is crucial for the viral-human DNA integration making integrase an ideal target for inhibitor design. However, in order to do so, force field parameters for the integrase magnesium ion need to be established. Quantum mechanical calculations were used to derive force field parameters which were validated through molecular dynamics studies. Our results show that the parameters determined accurately maintain the integrity of the metal pocket of the integrase CCD.

- Description: As an academic and applied discipline, sport psychology is interested in identifying, understanding, measuring and developing the various mental constructs that interact with physical factors, aiming to produce optimum performance and enhance athletes’ experience of sport participation. The programmes developed within sport psychology are not only applicable to sport, but have applicability within other areas, such as the performing arts, business and professions that are considered high risk, such as the military. Using a mixed methods approach and a triangulation of qualitative and quantitative data collection and analysis techniques, the goal of this research was to document the process of developing and implementing a psychoeducational mental toughness programme and to evaluate the programme through exploring the participant’s subjective experience of such a programme. The aim of the research was to contribute to the existing literature on mental toughness programmes. This was attained through administering the Sport Mental Toughness Questionnaire (SMTQ) and a semi-structured interview, which informed the development and implementation of a psychoeducational mental toughness programme relative to the idiosyncrasies of the participant and grounded in strengths-based approaches to mental toughness development. Results were obtained based on post-implementation data collected through a second administration of the SMTQ and a semi-structured interview. The participant experienced the programme as positive and results were indicative of changes in his experiences of self-confidence and control, related to the global themes of mindset, flexibility and mindfulness.

- Description: After the fall of the Apartheid regime in 1994, South Africa was presented with a myriad of reform challenges that originated due to a segregational rule. Distribution of land to those who were previously disadvantaged would become and is increasingly becoming a major challenge that the African National Congress (ANC) led government would need to address. Land reform progress and performance has become a key indicator of the African National Congress’ ability to govern after more than two decades as the majority party. The African National Congress led Government of South Africa proposed a target to redistribute thirty percent of agricultural land which was owned by the white minority by the year 2014, however as of 2012, only seven percent had been redistributed with an estimated ninety percent of the farms redistributed to black farmers no longer in commercial production (Lund, 2012). Numerous factors have been attributed to land reform failure in South Africa, including but not limited to, settlement support after receiving the land. Broadly speaking, the processes leading of land reform is categorised into two fundamental categories namely; pre-settlement project fundamentals or criteria and secondly postsettlement support. The lack of or inadequate post-settlement support systems and programs is identified as a major constraint to land reform success. This research effort is aimed at gaining an understanding of what exactly the post-settlement support programs and targeted intervention are and designing an appropriate support framework that aims to reduce land reform failures and ultimately contributing to land reform success, a more inclusive rural economy and a food secure South Africa. Lumet and Qualm quote Hall in their 2012 research as saying, “Land reform has become heavy on political rhetoric and short on detail.” Whilst the ANC led government has ended the ‘willing buyer willing seller’ policy and is looking to introduce other policies to expedite land reform settlements, a significant void exists in the detail regarding post-settlement support of land reform beneficiaries to ensure success and to maintain the productivity of the reformed farms. This study aims at creating a post-settlement support framework which will add some detail as described as lacking above. Ten research questions were formulated in which the answers to the questions collectively provide insight into the post-settlement support systems required for enhanced success. The research questions are not all directly related to the post-settlement function, but also speak to other factors that need to be adequately addressed for the post-settlement function to be framed successfully. The literature review aimed at providing a backdrop to the history of land reform policies, the success and failures thereof, but more importantly it sets the scene in which an efficient post-settlement support framework must prevail. According to the interpretivist paradigm, it is assumed “that social reality is in our minds, and is subjective and multiple” (Collis & Hussey, 2009). Social reality is therefore affected by the act of investigating it. The research involves an inductive process with a view to providing an interpretive understanding of social phenomena within a particular context” (Collis & Hussey, 2009). The research effort uses an exploratory case study method. This selected method was the best approach to use to achieve the research objectives, to answer the research questions, and to test the listed propositions. The purposeful sampling unit in this study refers to land reform projects which have been in existence for five years or longer since settlement. These black emerging farmers or farmer groups are beneficiaries of the South African governments’ land reform programme and they are therefore also beneficiaries of the post-settlement support functions. Purposeful sampling involves identifying and selecting individuals or groups of individuals that are especially knowledgeable about or experienced with a phenomenon of interest while Spradley (1979) notes the importance of availability and willingness to participate, and the ability to communicate experiences and opinions in an articulate, expressive and reflective manner.

The development of an optimised decision based methodology for the replacement timing of frontline equipment utilised within the quarrying industry

- Description: At present, frontline equipment employed at B&E International, and operating within the quarrying sector is typically replaced as soon as the operating expenses are deemed to be excessive. From a capital budgeting perspective, the trigger for signalling the replacement of equipment occurs when prescribed operating cost performance metrics are violated. In some instances, a further consideration for motivating the replacement of equipment is when the perception arises that the nonavailability of the equipment employed, results in financial losses being incurred by a company. It can therefore be argued that the current equipment replacement timing methodological approach adopted at B&E International is suboptimal in nature. The situation is further aggravated by the fact that in many instances, escalation of commitment manifests itself whereby unnecessary capital is repeatedly invested in order to extend the life of an asset resulting in a situation occurring whereby the required level of investment return is not achieved. In the event of these situations arising, the decision to replace an asset is prolonged as a result of the suboptimal investment decisions being made. The primary focus of this study is to provide a methodological equipment replacement framework that is based upon sound capital budgeting fundamentals. A comprehensive literature review of capital budgeting approaches that specifically focus on the optimal replacement timing of frontline quarrying equipment, did not yield any relevant studies that have been undertaken in this regard. This study did however investigate contemporary equipment replacement approaches based upon a capital budgeting paradigm and highlighted their respective limitations. Convincing evidence obtained, indicated that the most widely accepted method of identifying the optimal replacement timing of equipment occurs when the economic life of the asset is attained. This in itself would therefore infer that a cost minimisation approach is the most pervasive methodological approach adopted in order to identify the optimal replacement timing of equipment. When considering capital investment based decisions, it was found that the discounted cash flow based methodologies are the most widely used and accepted approach applied in the mining industry. Notwithstanding this, one major caveat manifests itself in that when considering the optimal replacement timing of front line equipment within the quarrying industry, the inclusion of uncertainty, flexibility and the associated financial risks was not evident. In order to model these effects, a probabilistic Net Present Value (NPV) approach was adopted and the required Discounted Cash Flow (DCF) models were constructed. Given the uncertainty of the expected cumulative R&M profiles for the asset classes constituting this study, an extensive statistical analysis was carried out in order to establish the required predictive Repair and Maintenance (R&M) models required for the DCF analysis by means of regression analysis. Further regression analyses were conducted in order to model the overall availability and utilisation metrics for the respective asset classes included in this study. The consequence of incurring downtime was investigated and the resultant DCF analysis yielded a significant impact on the Free Cash Flow (FCF) generated by the respective assets. The magnitude of the incurred consequential financial losses incurred as a result of the respective downtime was found to be significant when considering frontline equipment. In order to model the effect of, and the extent to which, the respective independent variables influence the static NPV outcome, a sensitivity analysis was performed. From this, the influence of the independent variables constituting the NPV model employed in this study, were observed. A Real Options Analysis (ROA) approach was initially employed in order to model the effects of FCF uncertainty and the results of carrying out this analysis indicated a minimal influence on the static NPV model referred to earlier. It was therefore concluded that from an equipment replacement timing perspective, the ROA approach did not provide a robust and accurate representation of the probabilistic NPV outcomes anticipated. In order to address these perceived shortcomings, an Monte Carlo Simulation (MCS) model was constructed and the requisite probability distribution functions representing the most influential independent variables determined from the sensitivity analysis were identified and subsequently analysed. The results of the MCS analysis yielded the expected NPV outcomes that were found to be far more conservative compared to the static NPV outcomes referred to previously. Furthermore, the concluding findings of this study indicate that in order to estimate the optimal time to dispose of an asset, a static NPV analysis must first be modelled and thereafter a probabilistic NPV analysis. The respective uncertainty aspects over the lifespan of the assets should be identified to be incorporated into the MCS model. This methodological approach therefore opposes the use of a strictly deterministic based approach and rather predicates the use of a probabilistic NPV based framework. This study further concluded that traditional DCF approaches fail to consider management flexibility in terms of adapting to uncertainty and to also reduce the possibility of “escalation of commitment” occurring as a result of sub-optimal equipment replacement timing decisions by management. The use and acceptance of the traditional DCF approaches are acknowledged, but in order to develop an equipment replacement methodological approach that considers uncertainty and risk on the one hand and also allows for the incorporation of real data over the assets lifetime on the other, the use of an MCS probabilistic NPV based model was found to be the optimal approach to be adopted. The result of updating the static NPV model with updated data as soon as it is obtained enables one to generate accurate probabilistic distribution functions required for the subsequent MCS analysis. By adopting this approach the study has concluded that one can obtain realistic and accurate NPV forecasts from the anticipated FCF estimates. The principal conclusion obtained from this study is that the optimal time in which to replace front line assets employed at B&E International is when the probabilistic net earnings profile, viz., NPV of the equipment is maximized.

- Description: The purpose of the research was to develop a procedure by which South African ceramicists can use locally sourced ceramic materials to create armature based art forms, without having to rely on the importation of raw materials. The study also investigated the suitability of wire armatures as well as variable temperature ranges applicable to this investigation. It was found that commercial clay slip bodies purchased from South African suppliers tended to crack when coated over wire armatures during the firing process. It was shown that by substituting South African ceramic raw materials in the John W. Conrad’s C25 casting slip and Jeremy Dubber’s Ascent casting slip formulae with the addition of paper pulp and potassium feldspar, reduced the problem of the clay cracking when applied to wire armatures. The addition of paper fibres gave the clay bodies strong adhesive qualities which allowed the clay them to adhere onto the wire armatures which prevented the dry clay coatings from chipping off prior to and after firing. The addition of potassium feldspar helped with the maturing point of both the clay bodies and helped fuse the clay particles together which strengthened the clay coatings after being fired to their respective maturing temperatures. A further application of hydrochloric acid 30% or Pro Grip Key Coat ® to the three wire armature types, being galvanized binding wire, galvanized diamond mesh and Kanthal wire prior to coating with the above two formulae improved the adhesion of the clay slips to the armatures. This prevented them from the tendency to slide off the wire during the dipping and pouring process and helped eliminate any cracks that formed during the firing process. However, the glazing of the clay slips above proved to be problematic where it was sought as a further enhancement of the clay coated wire armatures. A general-purpose earthenware glaze caused the fired clay coating to crack probably due to the increased tension between the wire, clay body and the glaze. This problem was solved by developing a low firing transparent glaze. Other decorative effects were achieved by the inclusion of 0.5% cobalt oxide into the low firing transparent glaze which produced a blemish free deep blue colour. A further effect was achieved using binding copper wire over the bisque ware and then glazing with the low firing transparent glaze. A smoke firing technique as well an application of a copper oxide wash to the bisque fired ware and then re-firing to the required maturing temperature produced pleasing results.

- Description: The study aims to develop natural fibre reinforced bio-epoxy composite for use as roof sheets, manufacturing and characterization to evaluate its suitability for building applications. In this study natural fibres such as flax and kenaf were selected to reinforce bio-epoxy matrix. Different weight ratios of flax and kenaf fibres were processed by needle-punching technique to produce nonwoven mats. The nonwoven mats and bio-epoxy matrix were prepared using vacuum assisted resin transfer moulding (VARTM) at room temperature until dry and cured. The effects of weathering and water aging on the static and dynamic mechanical properties of kenaf and flax composites were investigated. Flax fibre reinforced bio-epoxy composites were found to exhibit higher tensile strength at 25% fibre content of 41.5 MPa in comparison to the composites reinforced with kenaf fibres (33.0 MPa). With regards to the drop weight impact results, flax fibre reinforced bio-epoxy composites exhibited brittle failure. Water aging results showed that kenaf fibre reinforced bio-epoxy composites absorbed less water for all fibre contents in comparison to composites reinforced with flax fibres. The tensile strength and modulus of both the composites reinforced with flax and kenaf fibres were reduced after water aging. However, the composite reinforced with kenaf fibres showed the maximum reduction in tensile strength at 25% fibre content. After UV treatment both composites reinforced with flax and kenaf fibres showed a decrease in tensile strength of 6.25% and 30%, respectively. In comparison to kenaf, bioepoxy composites reinforced with flax fibres showed an increase in tensile modulus. Both composites reinforced with flax and kenaf fibres were found to be brittle and broke easily but no colour fading was observed after UV treatment. The dynamic mechanical analyses results showed that the incorporation of flax and kenaf fibres increases the storage modulus of the composites with the maximum storage modulus value exhibited by flax fibre reinforced bio-epoxy composite at 30% fibre content. The glass transition temperature of composites reinforced with both flax and kenaf fibres shifted to lower temperatures of 79 °C and 69 °C respectively, in comparison to 96 °C for bio-epoxy resin, with the incorporation of fibres.

- Description: The study details the experimental work on the development of rhenium(III) oxide nanoradiopharmaceuticals for imaging and therapy of disease states. The nanoparticles (NPs) were capped with covalently linked tetraaminophthalocyanine-folate and ethylenediamine-folate to enhance their targeting ability. The capping agents were successfully synthesised and structurally characterised using Ultraviolet-Visible Spectroscopy (UV-Vis), Fourier Transform-Infrared Spectroscopy (FT-IR), Proton Nuclear Magnetic Resonance (1H-NMR), and Liquid Chromatography-Mass Spectroscopy (LC-MS). The nanoparticles were characterised using UV-Vis, spectrofluorimetry, Transmission Electron Microscopy (TEM), dynamic light scattering (DLS) and Zeta potential. Nanoparticles of sizes between 10 and 100 nm size were envisaged to be suitable for applications in biological systems. The preferred surface charge for the uptake of NPs must be between -30 and +30 mV, Re2O3 NPs capped with ethylenediamine were found to have a surface charge of -49 mV as compared with NPs capped with ethylenediamine-folate which gave -18.6 mV. The cytotoxicity studies of the nanoparticles were tested against four different cell lines: MDA-MB-468, MDA-MB-231, MCF-7, and MCF-10A. The cell survival rate after treatment was done with different capped rhenium(III) oxide nanoparticles obtained at a 10 μM concentration showed more than 80% cell viability. A comparison was conducted based on different nanoparticle sizes of capping agents across the four cell lines of varying folate receptor. All the cell lines were compared, and it was observed that MCF-7 had high percentage of cell viability especially with the cells treated with folate conjugated nanoparticles. Further investigation was done on the effects of folate conjugates and the effects of size. It was observed that the tetraaminophthalocyanine-folate favoured the MCF-7, for large-sized nanoparticles. However, further work is required to test the cancer cell internalisation of the nanoparticles using TEM as well as the correct size for endocytosis. Thereafter, the mice model study will be carried out for investigation of biodistribution of particles in tumour tissue using hot isotopes (186/188Re) and this will be done in a radiophamarceutical laboratory.
