NEW ONLINE COURSE IN BIOFILM EUROBIOFILMS 2013 Director...

AV INFORMATION FOR YOUR PRESENTATION AT THE 21ST ECCMID/27TH ICC

Important points in brief:

We would like to inform you that each meeting room will be equipped with a PC and a data projector for PowerPoint presentations only. You can review your presentation at the speakers service centre (SSC), where it must be handed in at least one hour before your lecture, either via External Hard Disk, CD-Rom, memory stick, or your own laptop.

Further details and hints for computer based projections: 1. Preparation Store ALL your files in a unique folder (especially videos) Avoid animations and make sure video(s) play automatically when slide is displayed Colours: use light-coloured fonts for texts (white/yellow) on dark backgrounds or vice versa. A

strong contrast is important for good legibility Legibility check: step back 1,5 m from your computer, the text should be easily readable on

presentation mode (if not, you are using a too small font!) PowerPoint & Windows Versions from 95 to 2003 may be used

2. How to transport your MS-PowerPoint file to the Speakers Service Centre (SSC) On CD-Rom, External Hard Disk, memory stick or your own laptop

3. In the Speakers Service Centre (SSC) Please come to the SSC the day before or at least one hour before your lecture! Hostesses will be happy to welcome you in a relaxed and friendly atmosphere to help you

submit/finalise your presentation Highly experienced and skilled technicians will capture your presentation and store it on a server You then rehearse your presentation with the assistance of a technician Technicians will help you with PowerPoint and will ensure that your changes are updated on the

specific server 4. In the lecture room Via network your presentation is made available in your lecture room, on a presentation computer

operated by a technician With a touch-screen control at the lectern you can simply "ask" for the "next slide" or "previous

slide" There will be no possibility to connect your laptop at the lectern in the lecture rooms No overhead or slide projectors in the lecture rooms; no double projection No change in presentation in the lecture room by the technician or the speaker

Welcome Message

On behalf of the Organising Committee and the ESCMID Study Group for Biofilms (ESGB) it is our great pleasure to welcome you to “Eurobiofilms 2013” in Ghent. After the very successful Eurobiofilms meetings in Rome (September 2009) and Copenhagen (July 2011), this is the third biannual meeting organised by the ESGB.

It is clear from the number of submitted abstracts and registered participants that microbial biofilms continue to be a hot topic among microbiologists. This conference will cover both basic and clinical aspects of bacterial and fungal biofilms and we are convinced you will be impressed with the level and the diversity of the research that will be presented during these four days.

Despite the busy program, we hope that you will find some time to catch up with old friends and/or make some new friends. You will see that the wonderful city of Ghent presents itself with ample opportunities to do so!

Finally, we would like to thank the Federation of European Biochemical Societies (FEBS), the Research Foundation – Flanders, the Belgian Science Policy Office, the Faculty of Pharmaceutical Sciences of Ghent University and VIB for their support. In addition, support from ESCMID has allowed us to provide attendance grants to 14 participants. Without these partners the organisation of this meeting would not have been possible.

Oral presentationsBoth conference rooms are equipped with a PC and LCD projector. Presenters are advised to bring their presenta-tion (in powerpoint or pdf format) on a USB device and should identify themselves to the chairperson of their session in the break preceding their session the latest. Al-though laptop computers can be connected to the system, use of your own computer is strongly discouraged and presenters will be responsible to make sure that their com-puter can be connected. Mac users are required to bring all necessary adaptors to hook their computer up to the projection system.

• Speakers are requested to present themselves to the chair in the lecture room 10 minutes prior to the beginning of their session

• Please respect the time limits. Each topic is sched-uled to last for 15 minutes, which means approx. 10 minutes for the presentation leaving 5 minutes for questions. The moderator is responsible for the time table and will interrupt if a presentation ex-tends beyond the allocated time.

Poster presentationsPosters 1 to 107 should be mounted on Tuesday morn-ing and will be presented during the first poster session (Tuesday from 13.00 to 15.00). These posters need to be removed after the final session on Tuesday.

Posters 108 to 204 should be mounted on Wednesday morning and will be presented during the second poster session (Wednesday from 13.00 to 15.00). These posters need to be removed after the final session on Wednesday.

Material to mount your poster will be provided.

Posters that will not be removed at the end of the session will be removed by the organisers, who cannot be held responsible for damage to posters.

General Information

Congress venueGhent University Aula is located within walking distance from all hotels in Ghent.

Address: Ghent University AulaVoldersstraat 9GhentBelgiumTel: +45 70 23 50 56 (Congress Secretariat)

In 1816, the Dutch administration chose Ghent as founding place for a higher education institute. Simultaneously, the city council felt it needed a building to host official festivities and decided to construct the Aula Academica in the city centre. The then unknown architect Louis Roelandt was appointed to design it. The first stone was laid in 1819 and the building was inaugurated in 1826.

Nowadays the heart of the Ghent University beats in the Aula. Here, the students receive their diploma, diverse colloquia and debates are organised, and numerous prominent people are entertained and honoured. The Aula is used as the logo of the Ghent University and, as such, truly symbolises the Alma Mater.

Wireless internet connection at the conference venueWireless internet will be available through the Eduroam world-wide roaming access service developed for the international research and education community. This is only available for staff and students from participating institutions. Once inside the conference venue you follow your university or institution’s logon procedure. The settings at Ghent University are as follows: SSID: eduroamSecurity type: WPA2Encryption Type: AES
