Poster Session

Instructions for Poster Presentation

Due to the size of the poster boards your poster may not exceed 90 cm in width and 120 cm in height (portrait format). Materials for mounting the posters will be available at the poster areas.

Local organizers will provide the necessary materials for the setup, but please remember that there will be no possibility to print out the posters at the conference site.

Posters will have to be mounted between 08:00 and 08:30 in the morning and will have to be removed after 18:00 in the evening. During the poster viewing period the presenting author and/or co-authors are asked to be present at the poster in order to be available for questions and discussions.

The title and Author(s) Name(s) must appear on the top of the final poster. The poster should have a balance between the text and illustrations. The illustrations should have a bigger area of the poster. Font size should be large enough to enable reading from a certain distance. It is suggested the following font size:

  • Title: Size 70 (1,5cm H)
  • Author(s) Name(s): Size 50 (1cm H)
  • Text: Size 28 (0,7cm H)

Visa Information

I wish to remind that US and Mexican citizens must apply for a visa to come to Brazil, concerning Europeans citizens it depends of the country, so please get in touch with the nearest Brazilian Consulate in your country in this direction.

A natural question would be the type of visa you need. Since you will not be receiving income or employment in Brazil, a tourist visa is just fine.

In order to avoid bureaucracy delays, I advise you to apply for the tourist visa as soon as possible.

A partir del 16/05/2013, ciudadanos mexicanos portadores de pasaporte ordinario no necesitan de visa para entrar a Brasil cuando viajen con el propósito de desarrollar actividades de turismo, deportes, negocios, tratamiento médico, asistir a conferencias, eventos o ferias comerciales, en tránsito o cualquier otra actividad que no sea remunerada. Los viajantes a los cuales sea aplicable la exención de visa tendrán una estancia legal en Brasil de hasta 90 días, prorrogables por otros 90. La prórroga debe ser solicitada en la Policía Federal, 30 (treinta) días antes de caducar el plazo de estancia

Please let me know if you need an official letter of invitation sending an e-mail to eventos@impa.br / xbrazopt@gmail.com
