Sperner type theorems with excluded subposets
No full textLet F be a family of subsets of an n-element set. Sperner's theorem says that if there is no inclusion among the members of F then the largest family under this condition is the one containing all ⌊ frac(n, 2) ⌋-element subsets. The present paper surveys certain generalizations of this theorem. The maximum size of F is to be found under the condition that a certain configuration is excluded. The configuration here is always described by inclusions. More formally, let P be a poset. The maximum size of a family F which does not contain P as a (not-necessarily induced) subposet is denoted by La (n, P). The paper is based on a lecture of the author at the Jubilee Conference on Discrete Mathematics [Banasthali University, January 11-13, 2009], but it was somewhat updated in December 2010. © 2011 Elsevier B.V.

Hangzáskép, íráskép - Juhász Gyula : Anna örök
No full textThe author contrasts artistic recitals of Anna örök (Anna is forever), a poem by 20th century Hungarian poet Gyula Juhász (1883-1937). The principled subject of her analysis is the change of rhythm (from iambic to trochaic and vice versa) with regard to enjambment; specifically she examines how the written form is realized in the acoustic form of five reciters' performance

First report of a malignant collision skin tumour with malignant melanoma and anaplastic sarcoma components in a dog
No full textThis paper describes the occurrence of a rare skin tumour that has been removed surgically from the upper lip of a 13-year-old Tibetan spaniel. The tumour was 0.5 cm in diameter and macroscopically appeared as a single dermal mass, but histopathological analysis identified it as a biphasic collision mixed tumour. In the anatomically uniform tumour, 70% (4 mm in diameter) of the total parenchyma was formed by a high-grade sarcoma (with the presence of giant cells), and about 30% of it (1 mm in diameter) was a malignant melanoma (again with the presence of giant cells). The histologically distinct, but anatomically uniform tumour parts were separated by a macroscopically invisible, non-neoplastic epithelial process originating from the overlying hyperplastic epidermis. The two malignant components did not infiltrate the peritumoural vessels and each other’s substance. In the sarcoma part, the mitotic and apoptotic indexes were 32 and 8, respectively, whereas in the melanoma part the same parameters were 10 and 6, respectively. During the immunohistochemical investigations anti-α-SMA, anticytokeratin AE1-AE3, anti-Melan-A, anti-Ki-67 and anti-claudin-5 antibodies were applied. In conclusion, this is the first report of a primary cutaneous malignant biphasic collision mixed tumour formed by an anaplastic sarcoma with giant cells and a malignant melanoma
Adatok a győr-gyirmóti Holt-Rába lepkefaunájához (Lepidoptera)
No full textAfter the sudden death of the primary author of this paper, Gyula János Horváth (1961-2019), the lepidopterologist working around the Szigetköz and Győr his collection has been bought by the Rippl-Rónai Museum (Kaposvár). The documentation of this unpublished research was chosen from his written legacy. It contains significant data and information for the fauna of the Szigetköz. The post-editing and modification was carried out by the secondary author. The primary author publishes the results of his research focusing on nocturnal Micro- and Macrolepdioptera, that was carried out in 2004 around Holt-Rába, next to Győr-Gyirmót. Altogether 532 species were collected, 157 of Micro- and 375 of Macrolepidoptera, respectively. The more valueable and rare species are Cosmopterix orichalcea, Atremaea lonchoptera, Friedlanderia cicatricella, Arenosthola semicana, amongst some protected ones (Ostrinia palustralis, Euplagia quadripunctaria, Catocala fraxini, Xestia sexstrigata)
