Features of digital writing as a language activity in the context of modern online communication

The article focuses on digital writing, which intrudes on the domain of “live” interaction, largely replacing it and manifestating its specific language features. Modern online communication depends on many factors: the accessibility of the media platforms; forms of written online communication (official / unofficial); type of communication. Everyday digital written communication based on Internet channels leads to the fact that not only the conditions of written speech production are changed, but also the perception of the written text, namely, both writing and reading skills alter. With the advent of novel means of interaction such as the Internet, there has been a lot of research and widespread discussion of how digital media influence the change in the written form of communication. The article summarises the features observed on lexical, syntactic, punctuation and graphic levels

Ligophorus llewellyni n. sp. (Monogenea: Ancyrocephalidae) from the redlip mullet Liza haematocheilus (Temminck & Schlegel) introduced into the Black Sea from the Far East

Ligophorus llewellyni n. sp. (Ancyrocephalidae: Ligophorus Euzet & Suriano, 1977) is described from the gills of Liza haematocheilus (Temminck & Schlegel) introduced into the Black Sea from the Far East. Ligophorus llewellyni is closely related to L. pilengas Sarabeev & Balbuena, 2004, which parasitises the same host species. The two species differ in the morphology of the accessory piece of the copulatory organ and in some of the characters of the haptoral hard-parts. The morphometric variability of L. llewellyni and in its morphologically most similar congeners from the Black Sea is studied. Correlations between 30 morphometric characters of the haptoral hard-parts and the significance of each for species differentiation are examined. It is suggested that only 22 characters are useful as diagnostic criteria permitting the differentiation of morphologically similar species of Ligophorus

Isoperiodic deformations of the acoustic operator and periodic solutions of the Harry Dym equation

We consider the problem of describing the possible spectra of an acoustic operator with a periodic finite-gap density. We construct flows on the moduli space of algebraic Riemann surfaces that preserve the periods of the corresponding operator. By a suitable extension of the phase space, these equations can be written with quadratic irrationalities.Comment: 15 page

Quantitative magnetotail characteristics of different magnetospheric states

Quantitative relationships allowing one to compute the lobe magnetic field, flaring angle and tail radius, and to evaluate magnetic flux based on solar wind/IMF parameters and spacecraft position are obtained for the middle magnetotail, <i>X</i>=(–15,–35)<i>R<sub>E</sub></i>, using 3.5 years of simultaneous Geotail and Wind spacecraft observations. For the first time it was done separately for different states of magnetotail including the substorm onset (SO) epoch, the steady magnetospheric convection (SMC) and quiet periods (Q). In the explored distance range the magnetotail parameters appeared to be similar (within the error bar) for Q and SMC states, whereas at SO their values are considerably larger. In particular, the tail radius is larger by 1–3 <i>R<sub>E</sub></i> at substorm onset than during Q and SMC states, for which the radius value is close to previous magnetopause model values. The calculated lobe magnetic flux value at substorm onset is ~1GWb, exceeding that at Q (SMC) states by ~50%. The model magnetic flux values at substorm onset and SMC show little dependence on the solar wind dynamic pressure and distance in the tail, so the magnetic flux value can serve as an important discriminator of the state of the middle magnetotail.<br><br> <b>Key words.</b> Magnetospheric physics (solar windmagnetosphere- interactions, magnetotail, storms and substorms

Determination of resistance Candida spp. to antifungal agents with systemic action epsilometric method (E-test) with the species-specific characteristics of Candida

Evaluation of susceptibility of systemic antifungal agents against Candida spp. in recent years has been standardized and refined based on species-specific characteristics of Candida. In addition to new values clinical breakpoints were introduced epidemiological cutoff value. This value can serve as a sensitive marker of reduced susceptibility to the systemic antifungal agents. In our study was tested the resistance of fluconazole, voriconazole, posaconazole, anidulafungin, caspofungin, micafungin for 294 clinical strains of Candida spp. (2012–2014) from specimens of cancer patients. Definition of MIC was performed by epsilometric method (Е-test). The resistance to azoles in the average observed in 47.4%, to echinocandins – in 4.2%

Redescription of Ligophorus mediterraneus Sarabeev, Balbuena & Euzet, 2005 (Monogenea: Ancyrocephalidae) with some methodological notes

A redescription of Ligophorus mediterraneus Sarabeev, Balbuena & Euzet, 2005, based on original material from the Black and Mediterranean Seas, is presented and new diagnostic characters for its recognition are proposed. The unlikely wide range of variation in the angle between the shaft and point of the anchors, reported for this species and for some others in the genus, is analysed, and the structure of the ventral bar in Ligophorus spp. is described and its taxonomic significance discussed

Redescriptions of Ligophorus cephali Rubtsova, Balbuena, Sarabeev, Blasco-Costa & Euzet, 2006 and L. chabaudi Euzet & Suriano, 1977 (Monogenea: Ancyrocephalidae), with notes on the functional morphology of the copulatory organ

Redescriptions of Ligophorus cephali Rubtsova, Balbuena, Sarabeev, Blasco-Costa & Euzet, 2006 and L. chabaudi Euzet & Suriano, 1977 based on original material from the Black Sea, the Mediterranean Sea and the Sea of Japan are presented. A comparison of samples of these two species from different regions was carried out with the aid of principal components analysis. The occurrence of L. chabaudi on Mugil cephalus in the Sea of Japan was confirmed. The functional morphology of the male copulatory organ was examined, and the use of the shape of this structure in the taxonomy of Ligophorus Euzet & Suriano, 1977 is discussed

Forecast of geometric characteristics of low-temperature ceramics with multilevel hierarchical pore structure

On the base of micromechanics of heterogeneous media the approach of computer simulation of the process of low-temperature ceramic sintering being synthesized by additive technologies of layer-by-layer build-up of the original polydisperse mixture and subsequent sintering is offered. The possibility of refractory component skeleton formation at different structural levels, being determined by particle fraction size is taken into account. Formation of the skeleton of refractory components of interacting particles causes the formation of the pore structure, and non-uniform distribution of pores in the layer thickness determines the initial anisotropy of shrinkage of sintered ceramics
