The latest results from the WCOM 206 Excellence in Communication Award competition are in and we have two winners: Sophia Chen (Fall 2023 term) and Alan Fu (Winter/Summer 2023).

It has been such a pleasure to be part of the team that reads and ranks the undergraduate papers nominated by Communication in Engineering instructors each term. I have learned so much!

Now you can learn about the challenges of monitoring hormone levels for transgender and non-binary individuals, and about models to improve malignant brain tumour survival rates. These two were considered the best of their peer group and the full text of the papers have been added to the McGill Libraries’ repository, eScholarship.

Recommendation for Research and Development of Point of Care Lateral Flow Immunoassay Based Continual Saliva Hormone Monitoring by Sophia Chen

Transgender and non-binary individuals may use Hormone Replacement Therapy as part of their gender transition. During this process, hormone levels are measured using immunoassays, which typically include estrogens, testosterones and progesterones. While commercial solutions can automate blood testing, the blood collection process itself is difficult., invasive, and prone to complications. Because hormone levels change throughout the day, a more robust testing solution needs to be developed. Lateral flow assays, a low cost detection device can be developed for quantitative readouts of hormone levels. However, low concentration of the hormones of interest present in the saliva means that this solution cannot currently be used as a diagnostic device. Future investigation is necessary on detection antibodies that are used for this solution. Intended audience: a biotechnical company considering research and development towards hormone monitoring.

Comparative Review of Malignant Brain Tumor Models by Alan Fu 

Stagnant growth in malignant brain tumor survival rates indicates a need for more powerful models to advance tumor research and pharmaceutical testing. This paper comparatively analyzes three models: 3D cell line xenografts, genetically engineered mice models, and neoplastic cerebral organoids based on comprehensiveness, scalability, and accuracy criteria. 3D CLXs possess excellent scalability but are unappealing in all other aspects. GEMMs are favorable in the aspects of comprehensiveness and accuracy compared to 3D CLXs, but face issues regarding scalability. Finally, neoCORs outclass GEMMs in both comprehensiveness and accuracy while retaining modest scalability, leading this paper to conclude that neoCORs are the most viable model for future development. Future development of neoCORs, especially of assistive microfluidics devices, is strongly recommended.

“I’m currently working on my technical paper for the winter semester and I’m having trouble deciding on a topic for the paper. Are you the right person to talk to about this?” I have received this kind of question many times over the past few years. Finding a topic can be tricky! Here are some of my favourite ways that you can use to decide on an engineering topic to research for a course. Whether it’s for WCOM 206, CIVE 432, CIVE 664, MECH 532 or any other engineering course, hopefully some of these tips can help you hone in on a topic that will work well for you!

  1. Look up research areas of some of the professors in your department. Every engineering department has a list of professors and you’ll find links to their research areas from those lists. For example, here is the list of Civil Engineering professors: https://www.mcgill.ca/civil/people and if you click on any of their names, you will often see their research areas and/or a list of their publications.
  2. To get an idea of what other WCOM 206 students have done before, check out papers that have won the best paper contest here. They will give you ideas for how narrow a topic a good paper should have and possibly point you to topics of interest.
  3. I often get inspiration from this magazine on engineering education called Prism. Each issue has a section called “First look” where they talk about cool new engineering technologies.
  4. Engineering grand challenges. This is a list put together by the US National Academy of Engineering. There are lots of excellent ideas for research that is really needed in today’s world: http://www.engineeringchallenges.org/challenges.aspx.
  5. Canadian engineering grand challenges https://engineeringdeans.ca/en/project/cegc/ – these grand challenges are designed to help address the UN Sustainable Development Goals (SDGs).
  6. The Royal Academy of Engineering, the UK’s National Academy of Engineering, has put together a website on how engineering is addressing the UN Sustainable Development Goals https://raeng.org.uk/sdgs. There is a wealth of great research topics on those pages.
  7. It’s always good to pick a topic that you have a personal interest in. Have you done an internship already? If so, you could pick something related to that. If you haven’t done an internship yet, that’s okay. You can check out the kinds of internships that are available to McGill students and pick a topic related to one that sounds interesting to you. You’ll find internship opportunities for McGill students in MyFuture here. Similarly, even if you’re not ready to look for a job yet, you can look in MyFuture for jobs of interest. The kind of work that employers are hiring for could give you ideas for research topics you might want to learn more about.
  8. If there is a broad area of research you are interested in, you could skim a book on the topic, especially looking in the chapter headings to see if any of the narrower topics covered in the book interest you. You can find books on a topic by searching words in the library catalogue here and narrowing the results to books only.
  9. Similarly, if there is a broad area of research that interests you, you can search the topic in Compendex here. It’s normal that you will get thousands of results. Next, use the “Refine” limits on the left-hand side of the screen to select “Controlled vocabulary” à “View more”. A pop-up window will open with all the “tags” that have been assigned to the articles in the results list. As a way of narrowing your topic, check out what the tags are and select one or more that interest you.
  10. Check out past blog posts on this blog, the Turret! There are even some past student assignments posted that might give you some ideas.

I hope these suggestions will help you. If you have other ideas for ways of coming up with a research topic, I would love to hear about it! You can contact me at taradotmawhinneyatmcgilldotca .

If, after reading this, you could still use some guidance, please know that the engineering librarians at Schulich Library are always happy to meet with you for a research consultation where we can discuss with you further. You’ll find the engineering librarian for your department listed at: https://www.mcgill.ca/library/contact/askus/liaison.

Happy researching!

Thanks to WCOM 206 professor Terry Newman for her thoughtful feedback on this blog post.

Costs and Effectiveness of Roof Based Urban Heat Island Mitigation Strategies

by Gabriel Lacroix

The temperature of cities during summer keeps increasing due to climate change and the urban heat island phenomenon. These temperatures lead to increased mortality rates, discomfort, energy consumption, greenhouse gas emissions and contribute to deteriorating air quality. To alleviate the effects of this phenomenon, many effective mitigation strategies have been developed. In the highly urbanized areas where the urban heat island is the most problematic, roof area is abundant, making mitigation strategies like green roofs and cool roofs attractive. This paper compares the effectiveness of green and cool roofs at mitigating the urban heat island effect by evaluating the temperature reductions they provide, the lifecycle costs associated with them, and the added benefits from implementing them. This comparison found that green and cool roofs provide similar temperature reductions with cool roofs being more cost-effective and green roofs providing valuable added benefits.

Comparative Analysis of Carbon Capture Systems for Fossil Fuel-Fired Power Plants

by Sophie Allard

Power generation through the combustion of fossil fuels produces most of the world’s electricity; however, this results in considerable carbon dioxide emissions and harmful environmental effects. As global energy demands continue to rise, researchers have begun investigating strategies to mitigate emissions by fossil fuel-fired power plants and carbon capture and storage has emerged as a feasible and effective method of doing so. This paper provides a comparative analysis of three methods of carbon capture: post-combustion, pre-combustion and oxy-combustion capture. Post-combustion capture refers to the process of separating carbon dioxide from the flue gas produced by combustion through absorption in a solvent. Pre-combustion capture involves removing the CO2 from the fuel prior to combustion through a series of isolated reactions, leaving pure hydrogen to be burned for power generation. Oxy-combustion capture involves the combustion of fossil fuels in an environment of pure oxygen, such that the flue gas produced can easily be condensed to isolate the CO2. While these three systems are effective emission reduction strategies, pre-combustion capture is associated with the highest efficiency. However, given the high cost of implementing and running pre-combustion and oxy-combustion capture systems in coal or natural gas-fired power plants, post-combustion capture was determined to be the best solution, based on practicability, efficiency and economic feasibility. Through the employment of carbon capture, the emissions from fossil fuel-fired power plants could be significantly reduced in order to mitigate the alarming effects of climate change.

Written Communication

The latest winners of the WCOM 206 Excellence in Written Communication Award have been announced. Please join me in congratulating Paolo Fiorilli, Theodore Glavas, and Timothy Adams!

These undergraduate engineering students have excelled among their peers. Their winning papers have been added to our digital repository, eScholarship@McGill, and made freely available to the world. Take a look at the abstracts below and follow the title links to read the full text.

Winter/Summer 2020

Paolo Fiorilli – Analysis of Alternative Insulating Gases to Replace SF6 in Electric Power Equipment

SF6 gas is an excellent electrical insulator that has been widely used in the power industry for decades, but its status as a powerful greenhouse gas has led to increasing pressure to find an alternative. The objective of this paper is to compare the properties of two novel replacement insulators, Novec 4710 and Novec 5110, and show that Novec 5110 is marginally superior in warm climates. The analysis will be performed using three criteria: electrical properties, assessed through dielectric strength and using boiling point to determine suitable operating temperatures, toxicity, evaluating mainly the median lethal dose and operational exposure limit, and environmental impact, established through the gas’ global warming potential. The analysis will show that for climates where the temperature does not fall below 0, Novec 5110 is the ideal choice because it results in a 99.996% reduction in warming potential and is the safest substance to handle. It is therefore recommended that Novec 5110 be adopted for insulating purposes in warm climates, while Novec 4710 is an excellent second choice with better insulating potential and a lower environmental impact relative to SF6 that is more suitable for colder regions.

Winter/Summer 2021

Theodore Glavas – Future Data Storage Mediums for High-Capacity Solutions

The amount of data produced by humanity each day is set on an exponential trend. As data production increases, the demand for data storage also grows. Current storage technologies cannot keep up with the extreme rate of growth, so new approaches to data storage must be considered. Quartz glass optical storage, holographic storage and DNA storage are three promising technologies that may become widely used in the future. The crucial factors necessary for these storage technologies to succeed are their storage density, transfer speed and commerciality. As of now, quartz glass optical storage leads the way as the most promising solution for large volume, low access data storage. However, research into DNA sequencing from other unrelated fields could make DNA archival storage more appealing than quartz glass in the longer run.

Fall 2021

Timothy Adams – Stability of Transtibial Socket Suspension Systems for Clinical Recommendation

Most currently available transtibial prosthesis socket suspension systems do not adequately secure the prosthetic to the residual limb. This leads to impaired biomechanical functionality, prosthesis control, and harm to the residual limb skin. Hence, it is imperative that the optimal suspension system is determined to mitigate these effects. It is concluded that out of three suspension systems, the vacuum-assisted suspension is the optimal solution as opposed to the suction and pin-lock suspension systems. It is shown that the vacuum-assisted suspension yields the minimum amount of pistoning, the second highest negative distal interface pressure during the swing phase of the gait cycle, and the minimal amount of residual limb volume loss. Although the pin-lock suspension has a greater negative distal interface pressure, the system tightly squeezes the residual limb in the process. This indicates that the vacuum-assisted suspension is a superior solution in this respect as it produces a marginally lesser amount of pressure without bringing about residual limb skin issues.
