Mechanisms of subtropical plankton transport into the coastal waters of southern Primorye, a case of Paracalanus parvus
Authors: Nadtochy Victoria V. , Zuenko Yury I.
Published: July 2021

Results of long-term studies of zooplankton species in the Amur Bay (Japan Sea) are analyzed. Two seasonal «waves» of the allochtonous species are defined: the first in the early summer that is formed mainly by inter-zonal copepods spawning in the deep layers ( Metridia pacifica , Neocalanus plumchrus, Calanus glacialis ) and the second in the late summer that is represented by warm-water copepods of subtropical origin ( Calanus pacificus and Paracalanus parvus ) obviously transported from the southern Japan Sea by currents. The latter species is able to dominate in the zooplankton community of coastal waters in the early-autumn season. Variations of this mass species abundance in the Amur Bay under changes of wind-driven upwelling/downwelling circulation are investigated using an empirical advective model of its cross-shelf transport. There is found that strong summer southern on-shore winds (summer monsoon) are favourable for its high abundance but in these conditions it is transported toward the coast by the deep compensatory flow developed only after the summer monsoon change to the winter monsoon with opposite direction; that’s why the high abundance is observed in autumn, in September-October. In the years with weak summer monsoon the species is transported to the bay in mass by the surface on-shore wind-driven flow earlier, in August, but its number decreases after the monsoon change, so the maximum of abundance is not high. Patterns of the transport by cross-shelf currents depend supposedly on the depth of plankton concentration. Recent strengthening of summer monsoon causes heightening of P. parvus abundance in the coastal waters at southern Primorye, up to extreme high values in 2013, but climatic trend of the summer monsoon intensity is negative, so decreasing of this species transport toward Primorye coast and its abundance in the coastal waters, as the Amur Bay, can be expected in the nearest future.
Some updates to the method for calculation of parameters of bottom trawl system
Authors: Zakharov Egor A. , Kruchinin Oleg N.
Published: July 2021

The method for calculation of geometric parameters of trawl system proposed by F.I. Baranov is analyzed. The calculation includes evaluation of spacer force and drag for all elements of trawl system and solution of transcendental equation to find a distance between the otter boards of bottom trawl. Special attention is paid to considering and enhancement of common techniques for determining force and geometric parameters of some elements of trawl system, with identifying the most appropriate ways. The calculations and experimental data are compared for a trawl system using the Scanmar equipment for monitoring of fishing gear. The updated model simulates more adequately the forming of bottom trawl geometry, therefore it can be used for assessment of the catch area during trawl surveys conducted by bottom trawls.
Description of respiratory rhythm for white whales (Delphinapterus leucas) in captivity
Authors: Gushcherov Pavel S.
Published: July 2021

Parameters of external respiration are considered for white whales Delphinapterus leucas living in captivity on the observations in 2009-2012. Low respiration rate (on average 2.2 ± 0.3 breath per minute) and short apnea phase (no more than 1.7 minutes) were observed in the first days after the catch, but both parameters returned to normal values (3.0 ± 0.2 breath per minute, apnea up to 5.1 minutes) in the next 10-34 days. The respiration rate in the morning is higher in comparison with the evening. The respiration rate dependence on the whales motor activity, their age, and water temperature is discussed, as well.
Assessment of stock, spatial distribution, and recruitment of walleye pollock in the northern and eastern Bering Sea
Authors: Stepanenko Mikhail A. , Gritsay Elena V.
Published: July 2021

Abundance and biomass of walleye pollock Theragra chalcogramma in the Bering Sea exceeded the mean values in 2015 owing to the high-abundant year-classes of 2008 and 2012 and several medium-abundant year-classes (of 2006, 2009-2011, 2013, and 2014). In contrast to rather stable distribution on its spawning grounds, distribution of feeding pollock in the northern Bering Sea is very variable and depends on both biomass of the population and long-term and short-term variations of environments, as water temperature and zooplankton abundance. In some years including recent times (2005-2007 and 2010-2014), the pollock migrated earlier and faster into the northwestern Bering Sea and returned back to the eastern shelf also early: in late summer - early autumn. This scenario is supposedly conditioned by low zooplankton abundance over the Bering Sea that forces pollock to active feeding migrations, particularly a deficit of preferable food (large-sized zooplankton) on the north-western feeding grounds could be a reason for its leaving this area in late summer. Strength of pollock year-classes is highly variable, too, and depends mostly on young-of-the-year fish survival in winter. As usual, favorable conditions for reproduction and progeny survival, when strong year-classes appear, are observed in the years or short periods of transition from one state of marine environments to another, whereas long periods of either «warm» or «cold» regime are not favorable for forming of high-abundant year-classes of the Bering Sea pollock.

Why does the pollock (Theragra chalcogramma) abundance change
Authors: Shuntov Vyacheslav P.
Published: July 2021

Some common ideas about environmental factors that determine the patterns of migration (including timing) and stock dynamics of walleye pollock are critically analyzed with particular attention to the Bering Sea. There is shown that the conception of the migration timing dependence on food supply in the northern Bering Sea does not represent the real facts, as well as the conception of year-class strength dependence on winter mortality of fingerlings determined by food supply, especially in conditions of its deficiency. Periodicity of the pollock stocks dynamics associated with global changes of climatic and oceanographic factors is also called in question. Role of provincial factors in dynamics of the pollock populations is discussed and emphasized.
Proteolytic enzymes of pond fish: methods of isolation and properties
Authors: Dvoryaninova Olga P. , Antipova Ludmila V. , Sokolov Alexander V.
Published: July 2021

Methods of proteolytic enzymes isolation from muscle tissue and viscera of pond fish are viewed and their properties are investigated. Efficiency of enzymatic processes is determined by physical and chemical characteristics of the enzymes and, first of all, by their activity and stability. The cathepsins from muscle tissue of most pond fish are acidic and have the highest activity under pH 4.5-5.0. The substrate specificity of this enzyme complex predetermines its possible usage in pickling, particularly for reducing its time and improving organoleptic parameters of the product.
On steadyness of stereotypes in conceptions on marine ecology of pacific salmons (Oncorhynchus spp.)
Authors: Shuntov Vyacheslav P. , Temnykh Olga S. , Ivanov Oleg A.
Published: July 2021

Some conceptions on marine ecology of pacific salmons (Oncorhynchus spp.), established in the second half of the last century, are discussed from critical position, as overemphasizing of the sea surface temperature influence on distribution of salmons and formation of their year-classes strength, deficiency of food (particularly in winter time) and fierce competition for food, pink salmon «suppression» over other salmon species and own adjacent generations, limited carrying capacity of the Subarctic zone for salmons, distortion of the epipelagic communities structure in the North Pacific by mass artificial reproduction of chum salmon, etc. Most of these ideas have not been confirmed by the data of long-term monitoring in complex marine expeditions conducted by Pacific Fish. Res. Center (TINRO) in the Far-Eastern Seas and adjacent North Pacific waters since the 1980s till nowadays. The data show that pacific salmons are very ecologically plastic species with wide temperature range of habitat. Salmons are able to considerable vertical migrations crossing easily the temperature gradient zones and different water masses. They have wide feeding spectra. Migrating dispersed, they successfully get their ration, even in vast areas with relatively low concentration of prey (macroplankton and small nekton). Total biomass of all species of pacific salmons in the North Pacific does not exceed 4-5 million tons (1.5-2.0 million tons in the Russian waters), whereas the stocks of other mass species of nekton are hundreds of millions of tons. The salmons consume 1.0-5.0 % of the total consumption by nekton in the epipelagic layer in the western Bering Sea, 0.5-1.0 % in the Okhotsk Sea, 5.0-15.0 % at East Kamchatka, and less than 1 % in the Pacific waters at Kuril Islands, So, the role of pacific salmons in trophic nets of the Subarctic waters is rather moderate. Therefore, neither pink salmon, nor chum salmon can be seriously considered as the species responsible for reorganization of large ecosystems and fluctuating of other mass nekton species.

Authors: Narevich Irina S. , Kovekovdova Lidia T.
Published: July 2021

Concentrations of As, Cd, Pb, Hg, Se, Fe, Cu, and Zn in tissues of the commercial crabs and shrimps Chionoecetes opilio, Paralithodes camtschaticus, Pandalus borealis, Pandalus hypsinotus , and Sclerocrangon salebrosa from Primorye waters are determined. The samples were collected by research vessels of Pacific Fish. Res. Center (TINRO) in 2012-2016. Content of metals and arsenic in the soft tissues (from claws and phalanxes of crabs and abdomen of shrimps) was determined by atomic absorption analysis (fiery and flameless methods), using Shimadzu AA-6800 spectrophotometer and mercury analyzer DMA-80 Milestone. As, Cd and Pb concentrations were measured by electrothermal method, with graphite cuvette as an atomizer; Fe, Cu and Zn concentrations were measured in the acetylene/air flame, with single-slot burner as an atomizer and background correction by a deuterium lamp. The standard solutions of the metals were used for calibration. Generally, the microelement composition in soft tissues of all shrimp and crab species is similar. For all species, concentrations of the elements in the soft tissues decrease in the order: Zn > Fe > As > Cu > Se > Cd ~ Pb ~ Hg. All samples are distinguished by heightened concentration of Cu. The following ranges of the toxic metals concentration are observed (mg per kg of wet weight): Pandalus borealis As - 1.6-8.5; Cd - 0.03-0.15; Pb - 0.01-0.02; Pandalus hipsinotus As - 2.78-14.6; Cd - 0.01-0.13; Pb - 0.00-0.01; Sclerocrangon salebrosa As - 5.4-17.3; Cd - 0.01-0.04; Pb - 0.01-0.03; Chionoecetes opilio As - 9.4-14.0; Cd - 0.01-0.05; Pb - 0.01-0.05; Paralithodes camtschaticus As - 3.0-8.8; Cd - 0.0008-0.10; Pb - 0.001-0.009. Cases of exceeding the maximum permissible level of As are detected for all species: in 68.0 % of samples for Paralithodes camtschaticus , in 35.0 % of samples for Sclerocrangon salebrosa , in 33.3 % of samples for Panadalus hipsinotus , in 17.5 % of samples for Panadalis borealis , and in 17.0 % of samples for Chionoecetes opilio .

Authors: Skibitskiy Vitaliy V. , Vasil'ev Vladimir Yu. , Fendrikova Aleksandra V. , Pyatakov Stanislav N.
Published: July 2021

Background. Changes in the vascular wall, in particular, an increase in its stiffness and an increase in pressure in the aorta, as well as hypertrophy of the left ventricular myocardium are factors that determine a poor prognosis in patients with arterial hypertension. At the same time, the peculiarities of changes in arterial stiffness indices and left ventricular myocardial remodeling in patients with different sensitivity to salt loading have not been adequately studied.
Aim. To conduct a comparative analysis of the values of peripheral blood pressure and central aortic pressure, indicators of left ventricular myocardial remodeling in salt-sensitive and salt-resistant patients with arterial hypertension.
Materials and methods. The study involved 180 patients with arterial hypertension: 96 men and 84 women. The median age was 59 years. Salt sensitivity test was performed according to V.I. Kharchenko. All patients underwent 24-hour blood pressure monitoring, echocardiography. Indicators of peripheral arterial pressure and central aortic pressure, remodeling of the left ventricular myocardium were determined.
Results. According to the results of the test V.I. Kharchenko, 88 patients were classified as salt-sensitive, 92 as salt-resistant. After a salt sensitivity test in salt-sensitive patients, the main indicators of peripheral blood pressure and central aortic pressure exceeded those in salt-resistant patients in the daytime, at night, and throughout the day as a whole. In the group of salt-sensitive individuals, statistically more significant negative changes in echocardiographic parameters were recorded; a significant number of salt-sensitive patients were diagnosed with prognostically unfavorable variants of left ventricular myocardial remodeling.
Conclusion. In salt-sensitive patients with arterial hypertension, compared with salt-resistant patients, there are higher values of both peripheral blood pressure and central aortic pressure, more significant negative changes in echocardiographic parameters with the formation of concentric hypertrophy and eccentric remodeling of the left ventricular myocardium. It can be assumed that the assessment of salt sensitivity makes it possible to verify patients with the most unfavorable changes in parameters of ambulatory blood pressure monitoring and significant remodeling of the left ventricular myocardium. This approach can be used to individualize pharmacotherapy in patients with arterial hypertension and increase its effectiveness.

THE COGNITIVE-LINGUISTICS ANALYSIS OF THE CONCEPT «TIME» AS EXEMPLIFIED IN THE A. DE CUSTINE’S BOOK «LA RUSSIE EN 1839»
Authors: Гашков Сергей Александрович
Published: July 2021

Идеи когнитивной лингвистики (Дж. Лакофф, М. Джонсон, В.А. Маслова и другие) находят широкое применение не только в лингвистике, но и в междисциплинарной сфере. Целью статьи является применить когнитивно-лингвистический анализ к концепту ВРЕМЯ в книге А. де Кюстина «Россия в 1839 году». Доказывается, что алогичность и двойственность образа России у де Кюстина связана, в том числе, со спецификой понимания им концепта ВРЕМЯ.

The ideas of the cognitive semantics (J. Lakoff, М. Johnson, R. Langacker, L. Talmy) are used not only in linguistics, but in interdisciplinary sphere. The paper aims to apply the cognitive-linguistic approach to the concept TIME as exemplified in the A. de Custine’s book «La Russie en 1839». We prove that the ambiguous image of Russia is partly due to the specificity of the Custine’s concept of TIME.

Actualmente, uno de los problemas en la medicina veterinaria, es la resistencia antimicrobiana que se ha presentado en varios agentes patógenos. Los antimicrobianos que son usados comúnmente en veterinaria; Enrofloxacina, penicilinas, cefalosporinas entre otros, tienen un uso indiscriminado en medicina de animales de compañía y en grandes especies. Debido a la importancia de salud pública que las grandes especies representan para los humanos, el presente trabajo tiene como objetivo medir la resistencia antimicrobiana específicamente de aislados de Salmonella spp en bovinos lecheros. Los animales objeto del estudio fueron vacas Holstein con función zootécnica lechera, misma que se destina para la fabricación de quesos en la unidad de producción estudiada. Se aisló Salmonella spp la cual resultó ser multirresistente a mas de 3 antibióticos: ampicilina, carbenicilina, cefalotina, gentamicina y nitrofurantoína.

Usando una solución estática axial simétrica que describe un sistema binario de agujeros negros idénticos en un espacio-tiempo en cuatro dimensiones (4D), construimos y estudiamos a través de la estructura de barras, una solución en cinco dimensiones (5D), que contiene tres parámetros libres y es una solución de vacío para las ecuaciones de Einstein con tres vectores de Killing que conmutan. Dependiendo del valor de los parámetros, la solución 5D representa dos agujeros negros estáticos o un agujero negro estático en 5D. Además, presentamos una solución novedosa que representa dos agujeros negros idénticos en 5D por medio de la solución de Schwarzschild.

The study design was cross-sectional, and samples were selected by random cluster sampling, as many as 126 families consisting of 63 families from the very dense region (VDR> 200 people per Ha) and 63 families from a rather dense region (RDR, 121-160 people per Ha) in Bogor, West Java, Indonesia. The data were collected by interview using a questionnaire in March and April 2014 and analyzed using descriptive and comparison tests. The analysis showed that families in RDR had a lower density but had a higher crowd level than in VDR, so that families in RDR had to try harder to get non-physical privacy. RDR families had a higher source of stress, thus encouraging them to did more coping strategies. The analysis showed that families in RDR had higher objective well-being but lowered subjective welfare than families in VDR. Families in RDR had higher physical welfare and lowered social and psychological welfare than families in VDR. The research findings had implications for the importance of strengthening the family environment and developing research methodologies in the field of family ecology.

Dedication by Hieron of Syracuse in Olympia
Authors: Chies Enrico
Published: July 2021

The inscription, carved on a bronze Etruscan helmet, was found in 1817 among the ruins of Olympia. The text of the inscription is a dedication to Zeus made by Hieron, tyrant of Syracuse, after his naval victory over the Etruscans at Kyme (474-473 BC). The inscription provides scholars with informations about both Deinomenid’s communicative strategies in a Panhellenic context and Hieron’s politics at the beginning of the fifth century BC. A comparison between the inscription and Pindar’s Pythian I allows scholars to study two very different ways of celebration of the same military event.
