Click to embiggen the poster. This isn’t the full poster, but I’m not uploading a 30MB PDF. The videos can be read with a smartphone and a QR reader, or flip through my posts, as all the videos are on the flog somewhere.

I couldn’t make the Midwest Ecology and Evolution Conference, but I made a poster. It describes preliminary results from an aphid addition/exclusion experiment I conducted in the summer of 2011. Specifically, it examines the question of whether aphid infestation influences the presence of leaf damage by other herbivores. Hello everyone! This is Sebastian with another update on the x-ray machine. This post will discuss the various methods that can be used to determine the radiation dose of our x-ray machine. Below you will find my report on determining x-ray radiation doses.
Evaluating 3 methods for estimating radiation doses
Introduction: Objectives: Methods: Results: Comparison between manufacturer data and web calculator: The web calculator: http://www.radprocalculator.com/XRay.aspx The information given by the manufacturer is given in the following documents: MX-20 mR Ouput versus time.pdf The professionals offer the solution of a dosimeter. Conclusion: Since the manufacture data is most reliable it is the clear choice to use. The manufacturer data covers more information, such as time, voltage, as well as unit conversions for other factors. Considering that more information is provided more variations to experiments can be made and the radiation does would still be available after simple unit conversions. The other option presented by professionals would be to use a dosimeter to directly measure the radiation dose. This option would be the easiest way out of the three options, and would cater more to a researcher’s specific setting. If a dosimeter is available to use I would make this device my choice for determining radiation dose. Hi everyone! Maria here. Sorry that I have not posted since the end of summer, but please rest assured that I’ve not run away with my Dichanthelium seeds, but have been working on them for the past -what? 6 months? A long and intimate relationship indeed. Brief summary of what has happened: I did a pilot germination & growth study using bulk Dichanthelium seeds. The results of germination study is nicely summarized in this poster that I presented at Midwest Ecology and Evolution Conference (MEEC) in Cincinnati 2 weekends ago(?). MEEC was fun and presenting (yapping about) my poster was a lot less nerve-wracking than I had expected: The seedlings are currently growing in the growth chamber at CBG. (There’s pictures in the poster of seedlings in agar and in plug trays!) I shall put up some more pictures sometime in the future. I should also post the R script I used to analyze data and produce the graphs on the flog – unfortunately don’t have the file on this computer. Right now I’m working on scarifying Dichanthelium seeds for my maternal lines growth and germination experiment (probably should explain in better detail later, likely in another poster). Other good news you might find interesting: If you have any questions about Dichanthelium or anything I talked about, you’re welcome to get in touch. My email is right under the entry title. |
