Name(s): Creator (cre): Persaud, Malaika, Thesis advisor (ths): Emery, Neil, Thesis advisor (ths): Narine, Suresh, Degree granting institution (dgg): Trent University

Abstract: Heated leaf extracts of Euphorbia neriifolia (sweet aloes) are used traditionally in Guyana for asthma therapy, but the phytoconstituents have not been studied and phytohormones are generally unexplored in Euphorbia species. Phytoconstituents in asthma-effective traditional heated extracts were analyzed and compared with unheated leaves and latex extracts as screens to identify candidate… more

Bio-based Polymers from Epoxidized Vegetable Oils Modified by Metathesis

Year: 2016, 2016

Name(s): Creator (cre): Persaud, Avinaash Antonio, Thesis advisor (ths): Narine, Suresh, Degree committee member (dgc): Rafferty, Steven, Degree committee member (dgc): Metcalfe, Chris, Degree granting institution (dgg): Trent University

Abstract: The epoxides of oligomeric self-metathesized soybean oil (MSBO) and cross-metathesized palm oil (PMTAG) and canola oil (CMTAG) containing terminal double bonds were used to produce nonisocyanate polyurethanes (NIPUs) as well as anhydride, amine and thiol-cured epoxies. The synthesized NIPUs displayed metal adhesive properties for CMTAG and MSBO with MSBO being favoured… more

Hormonal Algae: A Source of Functional Fatty Acids

Year: 2016, 2016

Name(s): Creator (cre): Ramphal, Kira Elizabeth, Thesis advisor (ths): Emery, Neil, Thesis advisor (ths): Narine, Suresh, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University

Abstract: Based on an endogenous hormone study, three cytokinin type phytohormones; benzyladenine (BA), trans-zeatin (tZ) and methylthiol trans-zeatin (MeSZ), as well as abscisic acid (ABA) were exogenously added at three concentrations (10-7, 10-6 and 10-5 M) to cultures of Chlorella vulgaris in an attempt to alter growth rate, total lipid and fatty acid yields and fatty acid profile. Growth… more

Doing it Right: Eliminating Mercury Use in Gold Mining in Guyana

Year: 2016, 2016

Member of: Trent University Graduate Thesis Collection

Name(s): Creator (cre): Kishun, Vishol, Thesis advisor (ths): Narine, Suresh, Thesis advisor (ths): Wallschläger, Dirk, Degree committee member (dgc): Evans, Doug, Degree granting institution (dgg): Trent University

Abstract: The cyanidation technique is currently a viable technique for gold recovery that can replace the present amalgamation technique in Guyana. To implement this technique effectively, laboratory scale experiments and at scale runs were conducted to determine the best particle size of the ore, cyanide concentration, and leaching time. In addition, the profitability of cyanidation was compared… more

The Involvement of Endogenous Plant Hormones in The Regulatory Network of Fatty Acid Biosynthesis in Soybean Seed

Year: 2016, 2016

Name(s): Creator (cre): Nguyen, Thien Quoc, Thesis advisor (ths): Emery, Neil, Thesis advisor (ths): Narine, Suresh, Degree granting institution (dgg): Trent University

Abstract: The activities of phytohormones during the reproductive phase have been partially clarified in seed physiology while the biological role of plant hormones in oil accumulation during seed development has been investigated in part only. In this research, fatty acid (FA) contents and hormone profiles, including abscisic acid (ABA) and cytokinins (CKs) of seed samples in four different… more
