October 3rd

Dr. Louis Gosselin, Dept. of Biological Sciences, TRU

Information session:  Everything you always wanted to know about Graduate School (and scholarships) in science but were afraid to ask.

Abstract:

Not sure what you’ll do after you graduate from your bachelor’s degree, and wondering if a masters degree might, or might not, be the right path to follow? Then this information session is for you. We’ll explore what grad school is all about, when to do a masters degree, how to choose a supervisor and project, how to apply to a graduate program, scholarships, and more. This session is especially useful for students in 3rd & 4th year, from any field of science, who want to learn more about graduate studies; 1st & 2nd year students are also welcome.

Title: Evolution of radiotherapy treatment techniques for cancer patients

Abstract:

Radiation therapy is the treatment of cancer through high doses of radiation to cancerous tissue. Treatment techniques have evolved from treatment of skin cancer with low energy x-rays to treating deeper cancerous regions, such as the prostate, with the high energy photons produced with modern linear accelerators. As the photons have increased in energy, techniques have been implemented to help reduce damage to the surrounding healthy tissue. Collimation of radiation and modulation of the beam have improved the ability for physicists to correctly shape the beam to conform to the tumour, however side effects continue to occur. One of the most common cancer sites in men is prostate cancer, with the treatment causing uncomfortable side effects. A polyethylene glycol hydrogel has been produced to help reduce the side effects within patients and improve quality of life. However, the cost of the hydrogel may limit implementation clinically. Several predictive models will be presented in this talk to guide radiation oncologists in management of this treatment tool.

Hybrids and Hybridization – A Critique of Models in Chemistry

Abstract:

Hybrid atomic orbitals and hybridization are so entrenched as a standard model in chemistry as to have become almost a dogma. In this talk, I will critique the logical and practical use of this model in the teaching of chemistry. Moreover, to bring students into the 21st century, I suggest how the teaching of chemistry without hybrid orbitals will provide students with an enhanced education. The chemistry curriculum needs to be updated for pedagogical, ethical and Kondonian reasons.
