Risk captured through the volatility of stock markets stands as the essential concern for financial investors. The financial crisis of 2008 demonstrated that stock markets are highly integrated. Slovakia, Hungary and Poland went through identical centralist economic arrangement, but nowadays operate under diverse stock markets, monetary system and tax structure. The study aims to measure the risk level of the Slovak Stock Market (SAX index), Budapest Stock Exchange (BUX index) and Poland Stock Market (WIG20 index) based on the portfolio diversification model. Results of the study provide information on the diversification benefits generated when SAX, BUX and WIG20 join their stock markets. The study considers that each stock index represents an independent portfolio. Portfolios are built to stand on the available companies that are listed on each stock index from 2007 till 2017. The results of the study show that BUX generates the lowest risk and highest weighted average return. In contrast, SAX is the riskiest portfolio but generates the lowest weighted average return. The results find that the stock prices of BUX have larger positive correlation than the stock prices of SAX. Moreover, the highest diversification benefits are realized when Portfolio SAX joins Portfolio BUX and the lowest diversification benefits are achieved when SAX joins WIG20.
It is the theoretical background of the linguistic image of the world that serves as a base to the author to present Slovenian and Slovak magic formulae as the archaic strata of the language. She has chosen texts of the same type from the scope of Slovenian and Slovak peasants’ way of healing. The Slovak texts were collected by the author at the end of the 20th century, while the Slovenian texts which were set down earlier are quoted from Vinko Möderndorfer’s work. Apart from the common Central European attitude, the author also points out the unique, national, and linguistic features, all reflected by the linguistic image of the world.

This report describes the first disease outbreak caused by chimeric swine enteric coronavirus (SeCoV) on two pig farms in Slovakia in early 2015. The infection was introduced by import of two breeding boars which were placed in provisional quarantine in a unit not strictly separated from other healthy pigs in the same building. Subsequently, loss of appetite and diarrhoea were observed in both boars during the first three days in the isolation unit. The infection gradually spread to the farrowing area and throughout the farm in two weeks and later to another nearby farm. Yellow watery diarrhoea accompanied by dehydration and death was observed in piglets with a mortality ranging from 30 to 35%. In the absence of an available vaccine, the pregnant sows were dosed by mouth with a 10% suspension prepared from the intestine and faeces of infected piglets in warm water. Three weeks after dosing, new litters of piglets were born which remained healthy with no development of diarrhoea.

High molecular weight glutenin and
translocation employing the standard sodium dodecyl sulphate (SDS-PAGE) and acid (A-PAGE) polyacrylamide gel electrophoresis methods were classified in 43 Slovak wheat cultivars registered between 1976 and 2006. Total number of 9 alleles was detected at all
loci. The most frequent HMW-GS alleles were “Null” for
, 7+9 for
and 5+10 for
, respectively. At the same time these alleles also constituted the most frequent HMW-GS genotype and phenotype-0, 7+9, 5+10. Such HMW-GS combination was found in 48.8% of all genotypes analyzed in
. Eleven different HMW-GS genotype-phenotype combinations were found, occurring at various frequencies.
Natural and chemically modified zeolites from the Slovak Republic and Ukraine have been investigated as the adsorbents for the uptake of Cr(III). Model water solution of low radioactivity was used. The adsorption and desorption kinetics of chromium were established with the gradual radioexchange technique (tracer 51Cr) and flame AAS. The effect of the factors studied are examined and explained. The sorption coefficient , distribution coefficient KD, sorption capacity , sorption rate S, and leachability of Cr were calculated in neutral, alkaline and acidic aqueous solutions. The sorption capacity of the modified zeolites was found to be greater by a factor of 2 to 16 than that of the unmodified ones depending on the modifying solution applied. The leachability of chromium from loaded zeolites into the neutral solution was negligible. The leachability into alkaline and acidic solutions increased over 40%.
