The studies were carried out with the aim of optimizing microtubing promising potato varieties in aseptic culture. experiments studied such factors as use vessels various sizes (test tubes a diameter 25 mm and plastic containers 18x18 cm, into which 10 ml agar 400 liquid nutrient medium, respectively, poured, respectively), density planting plants (40, 60 80 stem explants), composition medium d...

zero tillage practices have a direct effect on soil microbial communities modifying soil productivity and sustainability. the crop sequences used can change the aforementioned properties, too. in this study, we evaluated the effect of crop sequences under zero tillage management on soil biological and chemical properties including vertical distribution of soil organic carbon, soil basal respira...

We propose a method for identifying diathesis alternations where a particular argument type is seen in slots which have different grammatical roles in the alternating forms. The method uses selectional preferences acquired as probability distributions over WordNet. Preferences for the target slots are compared using a measure of distributional similarity. The method is evaluated on the causativ...

After setting out the challenges posed by argument alternations for linguistic theory, this paper reviews the development of accounts of argument alternations over the last fifty years, documenting a shift from accounts that are primarily syntactic in nature to accounts with semantic and pragmatic components. The remainder of the paper consists of case studies of the developing understanding of...

Rats with lesions in the neostriatal region that belongs to the prefrontal system were trained in two versions of delayed alternation. They performed as proficiently as intact animals in a two-key operant chamber. The same operated rats took many more trials to reach criterion when subsequently compared with the same control group in a T-maze. This finding demonstrates that variants of delayed ...

Koskenniemi’s two-level morphology was the first practical general model in the history of computational linguistics for the analysis of morphologically complex languages. In this article we will reconsider one of the key innovations in Koskenniemi (1983), namely the treatment of consonant gradation in finite state transducers. We will look not at Finnish, but at two languages with a more exten...

This paper investigates the mixed mutation in Breton, an endangered language which has seen a gap in transmission. Initial consonant mutation is a highly salient feature of the language, but susceptible to change in the context of widespread bilingualism and an ageing population of speakers. We investigate to what extent a younger generation is continuing to maintain the mixed mutation, and fin...

1. The purpose of this paper is the establishment of classes of verbals according to the morphemic alternations of base-form finals; 2. Verbals which are subject to morphemic alternation are treated as single entries instead of as multiple entries; 3. The patterns of compatibility between a given set of compound suffixes and a class of verbal bases are designed to be suitable whether used as in...

That there exist two losing games that can be combined, either by random mixture or by nonrandom alternation, to form a winning game is known as Parrondo’s paradox. We establish a strong law of large numbers and a central limit theorem for the Parrondo player’s sequence of profits, both in a one-parameter family of capital-dependent games and in a two-parameter family of history-dependent games...
