Periodic solutions for conformable type non-instantaneous impulsive differential equations
Authors: Ding Yuanlin , Wang Jinrong
Published: August 2023

In this article we study a type of conformable non-instantaneous impulsive equation with periodic effects. We find a Cauchy matrix that can provide solutions of linear and nonlinear problems and prove some of their properties. Also we study the existence of periodic solution of different types of conformable non-instantaneous impulsive differential equation. Some examples also are given to illustrate our theoretical results. For more information see https://ejde.math.txstate.edu/Volumes/2021/94/abstr.html
Newton-Kantorovitch method for decoupled forward-backward stochastic differential equations
Authors: Aguchi Dai , Tsuchiya Takahiro
Published: August 2023

We formulate a Newton-Kantorovitch method for solving decoupled forward-backward stochastic differential equations involving smooth and degenerate coefficients with uniformly bounded derivatives. We show that it converges globally and its rate of convergence is exponential.

"Political Conflict In The Democratic Party: A Case Study Of Post-Munaslub Leadership Dualism In Deli Serdang, North Sumatra"
Authors: Novela Dinita Ayu
Published: August 2023

This journal broadly discusses one of the recurring issues that often befall political parties, especially in Indonesia, which is political conflict and factionalization. The case study referred to in this context occurs within the internal dynamics of the Democratic Party, particularly after the extraordinary National Congress (Munaslub) held in Deli Serdang, North Sumatra. The theoretical perspectives utilized are political conflict theory and factionalism theory. Political conflict theory, as proposed by Prof. Maswadi Rauf, posits that political conflicts arise from three factors. Firstly, the desire to compete for political positions or power. Secondly, differences in political policies. Thirdly, divergent views on political institutions. Meanwhile, factionalism theory, based on the ideas of Raphael Zariski, defines factions as intra-party groups whose members share the same identity and goals, and they collaborate to achieve those objectives. The research methodology employed is qualitative, supported by in-depth interviews and literature review techniques.

Open Science is a great concept (and recently described really nicely by Titus Brown, who said in part, “scientific progress relies on the sharing of both scientific ideas and scientific methodology.”) This is a wonderful ideal, and it describes how a lot of scientists would like to act. But as we know, most scientists don’t actually act this way, or at least not as strongly as they could. Why not?

Analysis of the influence of carbon fibers on the electrostatic properties of fabrics intended for the production of protective clothing
Authors: Đorđić Dragan , Petrović Vasilije , Pačavar Samir , Milosavljević Anita
Published: August 2023

The paper examined the electrostatic properties of fabrics, of which three fabrics contain 1-2% carbon fibers in their raw material composition. The electrostatic properties of six fabric samples were compared, of which three fabrics were produced from 100% cotton fibers and three fabrics were produced from polyester, cotton and carbon fibers in the following ratio: sample 1: cotton 75%, polyester 24% and carbon fibers 1%, pattern 2: polyester 54%, cotton 44%, carbon fiber 2%, pattern 3: polyester 66.5%, cotton 32%, carbon fiber 1.5%. Samples 4, 5 and 6 are made of 100% cotton fibers. The surface masses of the tested samples are approximate and range from 201.7 g·m-2 to 210.5 g·m-2. The aim of the work is to compare fabrics that contain admixtures of carbon fibers in their raw material composition in a percentage ratio of 1% - 2% with fabrics that are produced from 100% cotton fibers and that have been processed for the purpose of antistatic, to establish which fabrics and to what extent provide better protection against the accumulation of electrostatic charge and which better absorb it from their surface and drain it through the fabric. The tests were carried out according to the EN ISO 1149-3 standard using the method that measures the discharge of electric charges. The results showed that fabrics containing carbon fibers showed lower values of Er (maximum electric field strength recorded on the device with the sample being tested at the measuring position) and higher values of protection factor S.

Complex Processing of Lidar Survey Data of Marine Areas
Authors: Glukhov V. A. , Goldin Yu. A. , Zhegulin G. V. , Rodionov M. A.
Published: August 2023

The complex processing of data from the shipborne lidar survey of the Black Sea coastal areas was carried out. In this area, internal waves are often observed according to contact and satellite observations. The source of probing linearly polarized laser pulses in the lidar is a solid-state laser with diode pumping of the YAG: Nd active element with a pulse power of 20 mJ at a wavelength of 532 nm and a duration of 7 ns. The co- and cross-polarized components of the echo signal were recorded during the lidar survey. The cross-polarized component of the echo signal was mainly used due to its greater sensitivity to various kinds of inhomogeneities in the vertical distribution of hydrooptical characteristics. The purpose of processing is to identify quasi-periodic structures in the spatial distribution of the characteristics of lidar echo signals caused the propagation of short-period internal waves. Three processing methods were applied: the approximation method, the wavelet analysis method, and the Hilbert-Huang transform method. A large array of data obtained during 50 hours of lidar survey has been processed. Three 60-minute tracks containing quasi-periodic structures have been identified. The three processing methods results are in good agreement with each other and make it possible to obtain the most complete information about the parameters of the studied processes. The parameters of the recorded quasi-periodic processes are typical for internal waves observed in the coastal areas of the Black Sea. In the future, when processing a large amount of lidar sounding data, it is advisable to carry out fast processing by automated spectral methods at the first stage, and to carry out detailed processing by the approximation method only for those survey areas where quasi-periodic processes have been identified.
Spatial and Temporal Variability of the Characteristics of the River Plume Frontal Zone in the Kara Sea in the First Two Decades of the XXI Century
Authors: Konik A. A. , Zimin A. V. , Atadzhanova O. A.
Published: August 2023

The article is devoted to obtaining long-term physical and geographical characteristics of the River Plume frontal zone as a separate hydrological structure that forms at the boundary of the fresh surface layer of the Ob and Yenisei Rivers. The primary data for identifying the frontal zone are satellite measurements of surface temperature (MODIS Aqua, Suomi NPP-VIIRS), surface salinity (NASA SMAP) and sea level (AVISO) for the period from July to October from 2002 to 2020. The position and characteristics of the River Plume frontal zone were determined using cluster analysis, which was applied for the first time to an integrated set of remote satellite sensing data in this region. The results of the study showed that in the warm period of the year, the average long-term surface temperature gradient of the River Plume frontal zone was 0.08 °C/km, the surface salinity gradient was 0.1 PSU/km, and the area was 155,000 km2. During the ice-free period of the second decade of the 21st century, the temperature gradient of the frontal zone weakens by 0.04 °C/km, and the area decreases by 100,000 km2. The correlation analysis showed that the temperature and salinity gradients, as well as the area of the River Plume frontal zone, were determined by the volumes of the river discharge of the Ob and Yenisei and ice parameters in the warm period of the year. The article presents the obtained estimates of the relationship between the characteristics of the frontal zone and the volume of river discharge, ice cover and wind parameters, as well as the value of the atmospheric indices of the Scandinavian oscillation (SCAND).
Analytical Solution of the Ray Equations of Hamilton for Rossby Waves on Stationary Shear Flows
Authors: Gnevyshev V. G. , Belonenko T. V.
Published: August 2023

The asymptotic behavior of Rossby waves in the ocean interacting with a shear stationary flow is considered. It is shown that there is a qualitative difference between the problems for the zonal and non-zonal background flow. Whereas only one critical layer arises for a zonal flow, then several critical layers can exist for a non-zonal flow. It is established that the integrated ray equations of Hamilton are equivalent to the asymptotic behavior of the Cauchy problem solution. Explicit analytical solutions are obtained for the tracks of Rossby waves as a function of time and initial parameters of the wave disturbance, as well as the magnitude of the shear and angle of inclination of the flow to the zonal direction. The ray equations of Hamilton are analytically integrated for Rossby waves on a shear flow. The obtained explicit expressions make it possible to calculate in real-time the Rossby wave tracks for any initial wave direction and any shear current inclination angle. It is shown qualitatively that these tracks for a non-zonal flow are strongly anisotropic.

The paper presents the results of a study of the lifetime of wind-wave breaking (“whitecaps”) and the spatial distribution of the moments of wave-breaking initiation along the profile of a long surface wave. The results obtained during the specialized experiments from an oceanographic platform in the Black Sea are given. The registration of the whitecaps was carried out based on the video recordings of the sea surface. The surface waves’ characteristics were measured and the meteorological information was recorded simultaneously with the video recordings. It is shown that the distribution of the whitecaps’ lifetime is well described by an exponential law. It was found that the ratio of the lifetime of an individual whitecap to the period of the breaking wave is 0.3. The distributions of the above-mentioned ratio are similar for different wind and wave conditions. It is indicated that the generation of whitecaps occurs mainly in the region of the crest of a long wave with a shift to its front slope on average by 9.6 of the phase of the long wave. The whitecap having arisen at the leading edge shifts to the trailing edge of the long wave during its lifetime, so that the phase difference between the breaking initiation and the maximum of the surface fraction covered by the whitecaps equals 21.6.

The article describes results of the suspended particulate matter during 80th cruise of the RV Akademik Mstislav Keldysh in the Franz-Victoria Through, northern Barents Sea. Two perpendicular transections were carried out by means of small-angle laser diffractometer LISST-Deep operating in the red range with a wavelength of 670 nm. Observed data consist 7 thousand volume concentration and particle size distributions (PSD) measurements. Weather conditions during expedition allowed to extend the transection to southern part of Nansen basin. The volume concentration of suspended matter varied up to 7.58 μl/l in the euphotic zone and layer and from 0.2 to 0.5 μl/l in the nepheloid layer. Paper demonstrates construction possibilities of the particle size distributions profiles by depth. Transection comparison with measurement results by the conductometric method on a Coulter Counter of the bathometric samples were carried out.
Three-Dimensional Hindcast of Nitrogen and Phosphorus Biogeochemical Dynamics in Lake Onego Ecosystem, 1985–2015. Part II: Seasonal Dynamics and Spatial Features; Integral Fluxes

Published: August 2023

A three-dimensional coupled hydrodynamical biogeochemical model of the nitrogen and phosphorus cycles has been used for a long-term reanalysis of the Lake Onego ecosystem. The comparison between simulation and sparse irregular observations, presented in the first part of this paper, demonstrated plausibility of the reconstructed temporal and spatial features of biogeochemical dynamics at a long-term scale, while seasonal dynamics of variables and fluxes are presented here. As new regional phonological knowledge, the reanalysis quantifies that the spring phytoplankton bloom, previously overlooked, reaches a maximum of 500 ± ± 128 mg C m–2 d–1 in May, contributes to approximately half of the lake’s annual primary production of 17.0–20.6 g C m–2 yr–1, and is triggered by increasing light availability rather than by an insignificant rise in water temperature. Coherent nutrient budgets provide reliable estimates of phosphorus and nitrogen residence times of 47 and 17 years, respectively. The shorter nitrogen residence time is explained by sediment denitrification, which in Lake Onego removes over 90 % of the bioavailable nitrogen input, but is often ignored in studies of other large lakes. An overall assessment of the model performance allows us considering the model a necessary and reliable tool for scenario simulations of possible changes in the Lake Onego ecosystem at the requested spatial and temporal scales.

The paper proposes a variant of choosing the optimal solution to the large-scale scientific, technical and ecological-economic problem of the European part of the Russian Federation based on the integrated use of results of numerical modeling of hydrodynamic processes, expert environmental assessments and rating economic comparison.

The object of scientific research is the section of the Volga River from the Gorodetsky hydroelectric complex to Nizhny Novgorod (from 852.5 to 899 km along the ship’s course). The purpose of the work is to prepare proposals for the choice of an option for improving navigation conditions on the Volga River section under consideration in the lower reaches of the Gorodetsky locks under various flow regimes through the Gorodetsky hydroelectric complex, taking into account the priorities of environmental protection, protection of water bodies and use of water resources established by legislation. As a result of the work, a variant of the project proposed for implementation on the territory of the Nizhny Novgorod region for the rational solution of navigation problems on the Volga River, taking into account the assessment of the impact on the sanitary-epidemiological and environmental situation in the region, flooding and flooding zones. The project includes the construction of a third parallel lock in the area of Gorodetsky locks No. 15–16 and the creation of a navigable slot with a guaranteed fairway depth of 4.0 m.
Examples of the Water Dynamics Influence on the Spatial Distribution of Chlorophyll a Fluorescence Intensity in the Surface Layer of the Barents and Norwegian Seas

Published: August 2023

The influence of water dynamics on the spatial distribution of chlorophyll a fluorescence intensity in the surface layer of the Barents and Norwegian Seas, obtained during the 80-th cruise of the R/V “Akademik Mstislav Keldysh” using the flow-through measuring complex in August 2020, was demonstrated. The divergence of the current velocity field, calculated according to reanalysis data, was chosen as a parameter describing the dynamics of water masses. The application of the sliding correlations method allowed us to identify areas of the track with positive and negative correlations between the values of divergence and chlorophyll a fluorescence intensity. It is shown that a positive correlation is formed as a result of the vertical movement of the water surface layer, a negative one — may be a consequence of the water masses advection and the daily changes of the values of photosynthetically active radiation. The part of obtained results is confirmed by satellite data on the spatial distribution of chlorophyll a concentration.
Three-Dimensional Hindcast of Nitrogen and Phosphorus Biogeochemical Dynamics in Lake Onego Ecosystem, 1985–2015. Part I: Long-Term Dynamics and Spatial Distribution

Despite a wide-ranging research, there is almost no information regarding the major biogeochemical fluxes that could characterize the past and present state of the European Lake Onego ecosystem and be used for reliable prognostic estimates of its future. To enable such capacity, we adapted and implemented a three-dimensional coupled hydrodynamical biogeochemical model of the nutrient cycles in Lake Onego. The model was used to reconstruct three decades of Lake Onego ecosystem dynamics with daily resolution on a 2 × 2 km grid. A comparison with available information from Lake Onego and other large boreal lakes proves that this hindcast is plausible enough to be used as a form of reanalysis. This model will be used as a form of studies of Lake Onego ecosystem, including long-term projections of ecosystem evolution under different scenarios of climate change and socio-economic development.
XXI-st century: a shift of paradigm in the planetary boundary layer theory
Authors: Esau I. N.
Published: August 2023

At the beginning of 21st century, Sergej Sergeevich Zilitinkevich initiated a shift of the fundamental paradigm in the planetary boundary layer theory, and wider, in statistical hydromechanics of stratified flows. He held the position of the chair in meteorology at Uppsala University, Sweden in 1998–2003, where he and his colleagues consistently introduced a concept of turbulent potential and total energy and not least reviewed fundamental understanding of turbulent mixing in stratified flows. Zilitinkevich continued as a professor-emeritus at University of Helsinki, Finland, in 2004–2021, where he attracted prestigious mega-grants both in Russia and European Union. As such, he created and led a virtual international research institute — the third institute in course of his carrier in science — for development of theoretical foundations and practical implications of the new paradigm for turbulent energies. A network of researchers and practitioners established by Zilitinkevich continue their joint research in the Pan-Eurasian Experiment frameworks.
“The floods of the Neva, XVIII century”. Database
Authors: Malova T. I.
Published: August 2023

The problem of systematizing information about the historical floods of the Neva seems to be extremely urgent today. The construction of predictive models, the feasibility of building new hydraulic structures, planning of engineering, economic, environmental, social and cultural activities are impossible without a comprehensive analysis of information about floods. The official catalogs available to researchers, unfortunately, are not informative enough and are full of distortions. Working with a large array of numerical values characterizing the flood heights of the Neva of different eras, the inconsistency of these values, even within the framework of individual events, the importance of clarifying them in order to preserve all information aspects — all this led to the need to form the Database of floods. The main task of its creation is information support of research related to the restoration of distorted rows (or individual historical floods of the Neva).
On the transition of temperature regime of the White Sea Region to a new phase state

Changes in near surface air temperature (SAT) and vorticity of the wind speed field of the White Sea and the territory of the Murmansk and Arkhangelsk regions and the Republic of Karelia are investigated. We analyzed the monthly average NCEP/ NCAR reanalysis data for the period 1950–2020. The average surface air temperature growth estimated using a linear trend was +0.240C/10 years. Against the background of this linear growth, significant interdecadal changes in surface air temperature are observed. The following periods are highlighted: the strengthening of the continentality of the climate (1950–1976), a more maritime climate (1977–1998), and the rapid growth of surface air temperature (1999–2020). The transition from a period of increasing continentality of the climate to a period of a more maritime climate is associated with an increase in the influence of the North Atlantic on the region under study. A hypothesis has been put forward that the period of rapid growth of surface air temperature is caused by the transition of the climatic system of the western part of the Russian Arctic into a new phase state. The observed warming in the Arctic has caused a reduction in sea ice, which has led to an increase in solar energy absorption by the surface of the Barents and White Seas.
