Poster Session
This Friday evening was the occasion to organize a poster session. Three groups presented and explained their work. It combines text and graphics to make a visually pleasant presentation.
Then, as viewers walk by, our poster should quickly and efficiently communicate our subject. A Poster Session allows viewers to study and restudy your information and discuss it with you one on one.
Preparing a well-organized, visually-pleasant poster requires to plan well in advance. First, we must consider the audience and what type of poster we will create. Next, we have to gather our supplies and decide what information to include. From this point, we can start to work on the text and graphics.
By surfing on Internet, I discovered this website which gives some information about How to Present a Poster Session: http://educ.queensu.ca/~ar/poster.htm
I think there is some good advice about the global presentation.
From my point of view, it is important to be prepared for questions that people viewing our poster will ask us. We can’t put all information about our subject on the restrictive size poster so our response to questions demonstrates our knowledge of subject.
Cecile and I worked on the Lotus effect, but I will not describe our poster in this summary. According to me, it’s more interesting and constructive for all of us, to give comments and details about posters we discovered during the poster session.
Assma and Oliver presented us the paper making. Their poster had a good overall appearance. It was very pleasant to look at. A first glance gave us immediately a quick and efficient sum up about principal events of “ paper history ”. A second part described the main step of paper fabrication.
This presentation was clear. Maybe there was not enough text to explain graphics, but it was easy to read and well organized.
About the paper history:
In 3000 BC, the first paper appears: it’s the papyrus. With Ts’ai Lun, in 105 AC, it’s the birth of paper in the actual form, which we know today. We had to wait for the 15th century and the use of milds to produce paper more rapidly. In the 19th century, there was a mechanization of handwork and industries used chemicals process instead of textile waste to create paper.
During the 20th century, we assisted to an industrialization of fabrication.
The question raised by this subject is about the end of paper. We can ask ourselves if, with the development of the internet and informatics, paper is still useful.
From my point of view, it’s easier to read information on a book than on a screen. Besides, it’s more reliable to keep information writing. Even if there is a lot of a method to save files, I think informatics is less efficient to keep important information.
About the paper fabrication, I will quickly detail the main steps. Trees provide primary material. The forest is needed for its wood. We use cellulose in the paper industry. Fibers are bounding together by lignin. Then paper fibers are sent to sawmills, and after all this process, digester separate fibers in individual ones. Unblashed paper is washed and then the paper pulp is dried and pressed into cylinders. Eventually, paper machine manufacture sheets.
The second subject was landfill. This poster was less attractive even if the presentation was interesting. There was more white space and text size was too small to view comfortably. I think there was a lack of balance text/graphic.
Each year, in France, every person produces 925 pounds of trash. With this poster, we discovered different possibilities to treat waste. For example, we can use landfill, incinerator or landfill gas.
For all of these techniques, we must weigh up the pros and the cons of their use.
Incinerator has got some advantages; we can reach 90 % of compression waste, and there is a well mastery of energy recovery. But in the other hand, incinerator creates heavy gas emission and 10 % of wastes are not treated.
I think, the worst way to treat waste is landfill open dumps. They produce air pollution, bad smell. Moreover, they spoiled landscape.
To avoid these disadvantages, maybe we can use modern landfill, for which compression waste ranging is from 50 to 60 %.
This subject was attractive but maybe environmental issues are too important and general to be well treated in this poster session.
I appreciated this work in pairs. We haven’t comment a lot of posters but I think, everybody had time to explain his work and tended to present main points of his subject in an attractive and clearly way.
