This species is similar to P. hubbsi, P. valentinae, and P. somovi in counts, short gill opening, notched pectoral fin without rudimentary rays, and black peritoneum and gill cavity. It differs from all of them in its subterminal (vs clearly inferior) mouth, radials (3 small vs 4 large), head length (28 vs 20–24% SL), large gelatinous snout (43 vs 19–35% HL), interorbital width (61 vs 33–46% HL), and gill opening (extending ventrally in front of 2–3 rays vs 3–7).Published as part of Stein, David L., 2012, Snailfishes (Family Liparidae) of the Ross Sea, Antarctica, and Closely Adjacent Waters 3285, pp. 1-120 in Zootaxa 3285 on pages 65-66, DOI: 10.5281/zenodo.28312

New and Rare Snailfishes (Liparidae, Scorpaeniformes) with the Description of Four New Species from the Southern Hemisphere and Tropical East Pacific 1
No full text1 Liparid fishes of the Southern ocean, Australia and other areas have been intensively studied (Andriashev, 1986; Stein and Tompkins, 1989; Andriashev and Stein, 1998; Stein et al., 2001; Andriashev, 2003). Knowledge of the diversity in the family has substantially increased, and more than 334 species of 29 genera are listed (Chernova et al., 2004). However, many of the species are known from a few or single specimens. For these reasons every new record of Liparidae is of inter-est. The present study concentrates on snailfishes found in the large ISH–ZMH collections of the Zoological Museum of Hamburg University, mainly from the Southern Hemisphere and from the adjacent tropical east Pacific. The focus was to identify unstudied mate-rials, to record new localities and data and to describe new species. All specimens found belong to 2 genera: Careproctus Krøyer 1862 which includes more than 105 species, and Paraliparis Collett 1879 containing not less than 112 species. Careproctus differs from Paraliparis mainly by having a sucking disk which is reduced in species of the latter genus. Representatives of both genera are widely distributed in the shelf, bathyal, and abyssal parts of the world's oceans. 1 The text was submitted by the author in English. MATERIAL AND METHODS Recent revisions (Andriashev, 1986; Stein and Andriashev, 1990; Chernova, 2001; Stein et al., 2001; Andriashev, 2003) were used for species identification. Methods traditionally used in liparid studies, including radiography and pectoral girdle preparation, were pre-viously described (Burke, 1930; Stein, 1978; Andria-hev, 1986; Kido, 1988; Andriashev and Stein, 1998; Chernova, 2001; Stein et al., 2001; Andriashev, 2003). Meristics were taken from radiographs using: D as number of rays for the dorsal fin, A as number of rays for the anal fin, P as number of rays for the pectoral fin, and C as number of rays for the caudal fin. Vertebrae numbers were obtained separately for abdominal and caudal vertebrae (urostyle included). The principal caudal-fin rays are those supported by hypural plates. Dorsal (ventral) procurrent rays, when present, are those shifted forward to the upper-posterior (lower-posterior) edge of the hypural plates (Kido, 1988). Teeth of liparids are arranged in oblique rows, with a similar number of rows on the right and left jaws. We counted the rows on half of each jaw (usually left), and also the number of teeth in full rows near the symphysis of the jaws. The diastema is a toothless interspace between tooth plates of the right and left jaws.Publishe

Theoretical and methodological analysis of modern educational phenomena: Gamification, digitalization
No full textTheoretical and methodological analysis of modern educational phenomena: gamification, digitalization / N. Bakhmat, O. Ustymenko, L. Nikolenko, T. Chernova, V. Olyanych // Revista on line de Política e Gestão Educaciona, 2023. – Vol. 27. – № 2 (esp. 2). – P. 1–15.The positioning of digital and game segments as educational phenomena is an urgent issue in need of theoretical and methodological analysis. The aim of the article is to highlight the features of gamification and digitalization in the context of innovative development of education. The task of scientific exploration focuses on the harmonization of digital and game elements in the formation of the modern educational paradigm. The research methodology focused around the potential of general scientific (analysis, systematization, forecasting) and scientific and pedagogical methodological discourse (conceptualization, modeling). The results indicate that the digital and game components form the innovative dimension of educational strategies. At the same time, two ways of reconciling the key components of the educational space are distinguished: innovativeness & traditionalism and innovativeness vs traditionalism. Consequently, gamification and digitalization are the factors that determine the ratio of traditional and innovative components in educational development strategies

The com-petitive strengths for “Zorya”–“Mashproekt” products in the energy area for gas pipeline systems and ship GTEs are analyzed. A mathematical model is developed and the method for the rational projects portfolio formation at the enterprise which produces the GTI is pro-posed. Taking into account the capacity range of engines, the dynamics of supply of GTSPC “Zorya”–“Mashproekt” products applied to the stable tapped markets is studied. The methods of the GTE competitive growth by means of modernization of the operated ones and deve-lopment of the new ones are considered. A concept of formation of competitive production program of Ukrainian gas turbine enterprise is proposed.Определены основные направления управления содержанием проектов и программ повышения конкурентоспособности газотурбостроительной отрасли.

The safety and effectiveness of different methods of ear wax removal: a systematic review and economic evaluation
No full textEar wax (cerumen) is a natural secretion produced to protect the inner ear from dirt and other fragments by moving these particles towards the outer ear. If this process does not happen properly, wax may build up causing blockage in the ear canal and the possibility of impaction. People with a build up of ear wax may suffer from hearing loss, discomfort and, on occasions, infection. It may present problems in assessing hearing, blocking the view of the ear drum during medical examination and interfering with the fitting or function of hearing aids. Although it is thought to affect between 2% and 6% of the population in the England and Wales, some groups may be at a higher risk, such as those using hearing aids or with small ear canals and/or skin conditions. Recurrence is thought to be high among some of these groups. The consequences of the build up of ear wax in the ear canal are thought to be a common reason for consultation and cost in general practice with over 2 million consultations per year in the NHS.Methods of removal of ear wax include drops, flushing with water in general practice, and removal with suction or probes in specialist clinics. The relative safety and benefits of these different methods of removal remains uncertain. This research will systematically review published and unpublished evidence on the clinical and cost effectiveness of different methods for the removal of ear wax. Where appropriate, it will develop an economic model using data from this systematic review and other relevant sources to estimate the relative costs and benefits of different methods. In addition, the project will provide recommendations for future research to try to help answer any remaining areas of uncertainty
