Scope of the Conference

The conference is intended for all those interested in the grain size, strain and texture of solid state materials as revealed by X-ray powder diffraction analysis. It is hoped that a collection of contributions to be published after the conference will result in an authoritative book on powder diffraction.

Another objective is to illuminate the current methodologies and data interpretation models used by the participants of the round robin test on crystallite size and microstrain determination organized jointly by the Commission on Powder Diffraction of the IUCr and the JCPDS- International Centre for Diffraction Data.

The sessions of the conference will consist of invited and contributed papers given both orally and as posters. While only papers related to the X-ray powder diffraction analysis of the real structure of matter may be selected for oral presentation by Programme Committee, posters will be accepted from any field of crystallography.

Saturday, August 26, 1995

Trip to the historical Spis Region and to the High Tatras (only for persons interested) Information on short oral contributions and posters will be sent to the participants together with the more detailed information on transportation and accomodation in the third circular.

Instructions for Abstracts

Abstracts of all contributions, including invited lectures, together with a leading overview article will be published in a special issue of the journal "Materials Structure in Chemistry, Biology, Physics and Technology" which is published by the Czech and Slovak Crystallographic Association and will be available at the conference. They should be one page long and should have the following structure :

The abstracts extending significantly one page may not be published in full length in the proceedings. Longer contributions can be published separately after the conference. More information can be found on the address for correspondence and/or World Wide Web (see below). Although, the abstracts can be sent by mail it will be greatly appreciated, if the authors send the text as a computer file. The journal will be typed in two-column format by LaTeX, which should be preferably used by the authors. Other text processors ( MS Word, Ami Pro, Word Perfect) and/or ASCII text will also be accepted. The figures can also be in one of the common PC formats (PCX, TIF, GEM, etc.). The final width of the figures will be 8 cm. The references should be indicated by numbers in brackets and the list of references given accordingly at the end of contribution.

The abstracts can be sent in one of the following ways :

Authors are asked for using binary form for electronic mail (uuencode for E-mail, binary mode for ftp), if they don't send only pure ASCII file. The type of file, e.g. the type and version of word processor should be indicated. If an abstract is not acknowledged within a week, it is probable that it was not received. Please, check the E-mail account from which the abstract was sent. It may be used for questions.

If the manuscript contains special characters and/or figures, it should also be sent by mail or fax so that the editors have a chance for checking the corectness of the electronic form. Two week delay after the deadline for this mail is allowed. Note, that the address for mailing abstracts is different from the address of conference secretariat.

Location of the Conference

Liptovsky Mikulas
Liptovsky Mikulas is situated in Liptovska kotlina (Liptov valley), surrounded by beauty mountains: Low Tatras, West Tatras, Chocs Hills and Large Fatra. The town lies in the valley of the upper Vah river in the heart of the geographical, administrative and ethnographical centre known as Liptov since the 13th century.

Thanks to good geographical conditions this town became important centre of tourism. Liptovsky Mikulas has a rich history connected with the forming of Slovak independence. There are several museas and numerous historical buildings in the town.

Practical Information

The temperature in August in the Liptov region vary between 15C to 25C and weather is rather unpredictable. The conference will be held at the Military Academy campus. Liptovsky Mikulas can be reached by plane via Poprad, Kosice, Bratislava, Budapest (Hungary),Vienna (Austria) or Prague (Czech Republic) airports and from there by train (Poprad 1hr, Kosice 2.5 hrs, Bratislava 3.5 hrs, Vienna 5 hrs, Prague 8 hrs). Transportation from the railway station to the campus and between the campus and hotel will be organized the first day of the conference. Public transportation is available too (bus no. 5).

Participants will be accommodated in the centre of winter sports and tourism Jasna which is near to Liptovsky Mikulas. The registration desk will be opened on August 21st from 8.00 a.m. in the Military Academy. The exchange office and some travel services (train tickets, air tickets, reservations) will be available during registration.

More detailed information on transportation and accomodation will be sent to the participants in the third circular.

Trip to the historical Spis Region and to the High Tatras

Trip will be organized on Saturday August 26, 1995. Landmarks of the trip:

The High Tatras,
magnificent scenery of the smallest mountain range of alpine character in the world; the 26 km wide mountain chain of the glacial origin.
Levoca,
the historical town known as early as in the middle of the 13th century; the Gothic St James Church of the 14th century known especially for the altar by Master Paul of LevoŸa, several museas, citizen houses in the square valuable from the art-historical point of view.
The Castle Spissky Hrad,
the largest ruins in Slovakia, situated on a limestone tuff hill, imposing dominant point towering more than 200 m above the surrounding area. Originally a Romanesque castle of the 12th century, rebuilt several times, in the 15th century in Gothic, later in Renaissance style.
Markusovce
the Renaissance manor-house built in the 17th century, redesigned in rococo style, the museum of furniture. Inseparable part - the former French park with the rococo summer house Dardanely, at present the exhibition of historical keyboard musical instruments of Slovak origin.

Price of the trip (including lunch) - 25 USD - is to be paid at the conference. Please, indicate your interest in the registration form.

Programme for accompanying persons :

Accompanying persons can take part in evening social programme and afternoon excursion. A special trip to the High Tatras (ætrbsk‚ Pleso, Stary Smokovec, Tatranska Lomnica) with a guide can be organized, if the number of participants exceeds 30 persons.
