Dear Isotopists, Please find below the 3rd circular of the Isotope Workshop III containing a tentaive program. The program has changed a little during the last days, some people cancelled their registration, but it is still informative. Late registrations are still wellcome, posters are preferred, but talks are also possible. Only the abstract volume is finished, thus can't be supplemented. Looking forward to hearing from you, Attila Demeny ************************ Third Circular Isotope Workshop III Budapest, Hungary 24th to 28th of June, 1996. Isotope Workshop III will be an international meeting organized by the International Isotope Society (established in Poland in 1992) and the Laboratory for Geochemical Research of the Hungarian Academy of Sciences. The aim of the meeting is to provide a forum for a wide spectrum of isotope research, as well as a possibility to discuss recent research activities of members of the International Isotope Society and non-member participants from all over the world. Organizing committee: Chairman: Attila Demény Secretary/treasurer: István Fórizs Address: Laboratory for Geochemical Research, Hungarian Academy of Sciences, Budapest, Budaörsi út 45., H-1112, Hungary. tel/fax: 36-1-185-1781 (it will change to -36-1-319-3145) e-mail addresses: [log in to unmask] or [log in to unmask] Venue The meeting will be held at the Laboratory of Geochemical Research. This institute employs 30 people, among them 15 researchers. The research topics cover the whole range of geochemistry from mantle-derived rocks to environmental problems. A stable isotope laboratory is also established here. The institute has several meeting rooms, among them a large one with more than 100 seats. Budapest is the capital of Hungary, providing a wide range of amusement. One can enjoy the historic atmosphere of the medieval castle, glittering shopping streets, museums, restaurants of all classes, as well as the sight of hills beside River Danube with bridges illuminated by strings of lamps. Registration fee The registration fee of Isotope Workshop III is 200 USD, which covers one copy of the Abstract volume (Supplement of Acta Geologica Hungarica), dinners and refreshments during the Workshop, banquet, presentation and organization costs. The registration fee for members of the International Isotope Society is reduced to 180 USD. Students' fee is 120 USD. Payment Payments can be made by check, bank transfer, or in cash. Although the registration fee can be paid personally at the registration desk, the participants are kindly requested to send their fee in advance (in May) in order to help organizing. Checks should be payable to the "Res. Labs for Nat. Sci. of the Hung. Acad. of Sci." with a notice "Isotope Workshop III". By bank transfer the registration fee can be sent to the Hungarian National Bank (Budapest, Szabadság tér 8-9., H-1054) account number MNB 10032000-01717376 also with the notice "Isotope Workshop III". Grants Due to the financial support provided recently by the Hungarian Academy of Sciences and by the Laborexport Ltd., participants from developing countries can apply for supporting their registration. Because of the shortage of time, those who whish to apply should send their application in due course either by fax or e-mail. The application should include a statement that the applicant can cover other expenses from independent sources. Those applicants who can cover a part of the registration fee will have priority. Accommodation Hotels and dormitories are within walking distance from the venue of the Workshop. Lodging will be provided for the participants in: - dormitory room with 2 beds with bathroom. Cost: cc. 10 USD/person/night, - hotel, double room. Cost: cc. 70 USD/night, - ****hotel single room. Cost: cc. 150 USD/night. PLEASE CONFIRM YOUR PARTICIPATION BY E-MAIL OR FAX IN ORDER TO ENSURE LODGING RESERVATION with the exact date and time of your arrival and departure!!! POSTER SIZE: width: 1 meter height: 1.2 meter !!!! Meeting of the International Isotope Society The IIS was established in 1992 in Lublin, Poland, during Isotope Workshop I. Since that time the Society has grown to have members from 11 countries, mainly of Central Europe, but researchers outside Europe have also registered. The aim of the meeting is to discuss the activity of the IIS in the period of 1994-1996 and the future of the Society. Every participant is kindly invited to take part in this meeting and to become a member of this not only scientific, but friendly Society. Decision on next meetings will also be made after hearing of the conditions at the proposed places. All who are interested in organizing Isotope Workshop IV should prepare for a presentation of their institute and plans, and should inform the organizers of the present meeting in advance in order to include their proposal in the workshop's program. Non-scientific program The organizers offer the possibility of sightseeing of Budapest by bus. The estimated cost will be cc. 20 USD/person. Anyone interested in this program is asked to indicate her/his intention on the response form. Tentative program (based on the abstracts received) In the followings a tentative program of the workshop is given. However, those who would like to change their presentation schedule should contact the organizers immediately. Due to the informal character of the workshop, further poster presentations can be accepted. Those who have not registered but would like to take part, should send the attached registration form at their earliest convenience. Monday, morning. Registration. Demény, A. and Fórizs, I.
