The aim of this study was to assess sand accumulation in the gastrointestinal tract and fecal sand excretion in Silesian foals using three diagnostic methods and taking into account the sex and age of the animals. Another aim of the study was to compare the three diagnostic methods. The study was carried out on 21 clinically healthy Silesian foals (10 females and 11 males) from 9-28 weeks old grazed on permanent pasture. The sand intake was assessed using a sedimentation test, abdominal ultrasonography and a quantitative evaluation of sand per 100 g of stool. In the sedimentation test, the sand was palpable in the stool of 57.1% of the horses, and clearly visible in 42.9% of the animals. The ultrasound examination revealed the presence of sand in the gastrointestinal tract in 66.7% of the horses. It was limited to a single location in 60% of the horses, while it was present in several regions in 40% of the horses. The mean amount of sand was 0.14 ± 0.33 g per 100 g of stool. It did not exceed 0.1g in 71.4% foals, while it ranged from 0.1-0.5 g in 23.8% foals. In 4.8% of the animals, it amounted to 1.6 g per 100 g of stool. There was no correlation between age and gender and the results. There was a positive correlation between the ultrasound examination and the sedimentation test. Sand may be accumulated in the gastrointestinal tract of foals without any clinical signs. The amount of sand excreted in the stool is not an indicator of the amount of sand accumulated in the gastrointestinal tract. An abdominal ultrasound examination should be combined with a sedimentation test for more specific results.
Launched in Cracow in 1908, Slavic Yearbook ~ Revue Slavistique is one of the oldest journals of Slavic linguistics in Europe. Volume 50 (1997) features a bibliography of the journal covering the years 1908–1997 and the bibliography presented above, covering the years 1998–2018, is its continuation. The bibliography includes the following sections: 1. The composition of Editorial Committees and Boards; 2. Articles, dissertations, notes and reports (in an alphabetical order according to the names of the authors in their original versions, all names written in Cyrillic have also their transliterated equivalents); 3. Reviews (in an alphabetical order according to the names of the authors, titles of reviewed works or titles of reviews); 4. Miscellany (obituaries, memoirs and editorial notes); 5. Name index including names of the authors of articles, notes, reports and reviews, authors and editors of reviewed books, and names mentioned in the titles of works included in the Bibliography. For the last 20 years 130 Polish and foreign authors have published their articles in Slavic Yearbook. The journal has published 165 articles and dissertations in various areas of Slavic linguistics, 110 reviews and write-ups (including comprehensive reviews discussing several works on related subjects and multi-authored monographs) and 16 memoirs and obituaries.
The article presents an experimental-theoretical analysis of fluidised-bed drying of poppy seeds directed on minimisation of energy. The analysis was performed for a complete drying node incorporating a heat exchanger and a fan. Two complementary factors were used in the exergetic evaluation: exergy efficiency and unit consumption of exergy. An analysis of drying in stationary bed was carried out for comparison purposes. Results of the exergetic analysis can become a basis for innovative works focused on decreasing energy consumption of a technological node being analysed, e.g. by the use of recirculation of fluidising-drying medium.
