Their tribological performance, such as low friction coefficient, low surface energy and high heat resistance, make them an appropriate choice for anti-sticky coating application in moulds for food processing industry. This study is dedicated to evidence the transfer of contaminants from the coating due to wear and thermal ageing of the mould. The risk of contamination is induced by the damage of the coating by bread crust during the demoulding stage. The study focuses on the wear resistance and potential transfer of perfluorinated polymer from the anti-sticky coating. Friction between perfluorinated coating and bread crust is modeled by a tribological pin-on-disc test. The cellular nature of the bread crust is modeled by a polymer foam. FTIR analysis of the polymer foam after friction allow the evaluation of the transfer from the perfluorinated coating to polymer foam. Influence of thermal ageing on the physical, chemical and wear properties of the coating are also investigated. FTIR spectroscopic results show that the increase of PFA transfer onto the foam counterface is associated to the decrease of the friction coefficient. Increasing lubrication by film transfer results in the decrease of the friction coefficient. Moreover increasing the friction test parameters conditions (load, speed and sliding distance) also increase the film transfer onto the counterface. Thermal ageing increases the hydrophobic character of the PFA coating and thus also decreases the friction coefficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluorobased%20polymer%20coatings" title="fluorobased polymer coatings">fluorobased polymer coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=FTIR%20spectroscopy" title=" FTIR spectroscopy"> FTIR spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=non-stick%20food%20moulds" title=" non-stick food moulds"> non-stick food moulds</a>, <a href="https://publications.waset.org/abstracts/search?q=wear%20and%20friction" title=" wear and friction"> wear and friction</a> </p> <a href="https://publications.waset.org/abstracts/55552/tribological-properties-of-non-stick-coatings-used-in-bread-baking-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55552.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Cassava Plant Architecture: Insights from Genome-Wide Association Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Olayinka">Abiodun Olayinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Dzidzienyo"> Daniel Dzidzienyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Pangirayi%20Tongoona"> Pangirayi Tongoona</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Offei"> Samuel Offei</a>, <a href="https://publications.waset.org/abstracts/search?q=Edwige%20Gaby%20Nkouaya%20Mbanjo"> Edwige Gaby Nkouaya Mbanjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiedozie%20Egesi"> Chiedozie Egesi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Yusuf%20Rabbi"> Ismail Yusuf Rabbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cassava (Manihot esculenta Crantz) is a major source of starch for various industrial applications. However, the traditional cultivation and harvesting methods of cassava are labour-intensive and inefficient, limiting the supply of fresh cassava roots for industrial starch production. To achieve improved productivity and quality of fresh cassava roots through mechanized cultivation, cassava cultivars with compact plant architecture and moderate plant height are needed. Plant architecture-related traits, such as plant height, harvest index, stem diameter, branching angle, and lodging tolerance, are critical for crop productivity and suitability for mechanized cultivation. However, the genetics of cassava plant architecture remain poorly understood. This study aimed to identify the genetic bases of the relationships between plant architecture traits and productivity-related traits, particularly starch content. A panel of 453 clones developed at the International Institute of Tropical Agriculture, Nigeria, was genotyped and phenotyped for 18 plant architecture and productivity-related traits at four locations in Nigeria. A genome-wide association study (GWAS) was conducted using the phenotypic data from a panel of 453 clones and 61,238 high-quality Diversity Arrays Technology sequencing (DArTseq) derived Single Nucleotide Polymorphism (SNP) markers that are evenly distributed across the cassava genome. Five significant associations between ten SNPs and three plant architecture component traits were identified through GWAS. We found five SNPs on chromosomes 6 and 16 that were significantly associated with shoot weight, harvest index, and total yield through genome-wide association mapping. We also discovered an essential candidate gene that is co-located with peak SNPs linked to these traits in M. esculenta. A review of the cassava reference genome v7.1 revealed that the SNP on chromosome 6 is in proximity to Manes.06G101600.1, a gene that regulates endodermal differentiation and root development in plants. The findings of this study provide insights into the genetic basis of plant architecture and yield in cassava. Cassava breeders could leverage this knowledge to optimize plant architecture and yield in cassava through marker-assisted selection and targeted manipulation of the candidate gene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manihot%20esculenta%20Crantz" title="Manihot esculenta Crantz">Manihot esculenta Crantz</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20architecture" title=" plant architecture"> plant architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=DArtseq" title=" DArtseq"> DArtseq</a>, <a href="https://publications.waset.org/abstracts/search?q=SNP%20markers" title=" SNP markers"> SNP markers</a>, <a href="https://publications.waset.org/abstracts/search?q=genome-wide%20association%20study" title=" genome-wide association study"> genome-wide association study</a> </p> <a href="https://publications.waset.org/abstracts/168860/cassava-plant-architecture-insights-from-genome-wide-association-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168860.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">69</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Identification of Candidate Gene for Root Development and Its Association With Plant Architecture and Yield in Cassava</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Olayinka">Abiodun Olayinka</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Dzidzienyo"> Daniel Dzidzienyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Pangirayi%20Tongoona"> Pangirayi Tongoona</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Offei"> Samuel Offei</a>, <a href="https://publications.waset.org/abstracts/search?q=Edwige%20Gaby%20Nkouaya%20Mbanjo"> Edwige Gaby Nkouaya Mbanjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiedozie%20Egesi"> Chiedozie Egesi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Yusuf%20Rabbi"> Ismail Yusuf Rabbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cassava (Manihot esculenta Crantz) is a major source of starch for various industrial applications.
