Туннельная проводимость и туннельное магнитосопротивление пленок Fe-SiO: корреляция магнитотранспортных и магнитных свойств
Authors: Балаев Д.А. , Балаев А.Д.
Published: June 2019

The paper presents the results of a study of the electrical properties of a system of nanogranular amorphous Fe-SiO films with a SiO concentration from 0 to 92 Vol.%. For samples with a low SiO content, metallic conductivity takes place. With an increase of the dielectric content, a concentration transition of conduction from the metallic regime to the tunnel regime at a dielectric concentration x  0.6 is observed. At the same concentration, a transition ferromagnet - superparamagnet occurs, which was previously investigated by the magnetic method. For compositions corresponding to the dielectric region, the temperature dependences of the electrical resistance (T) follow the law (T) ~ exp(2(С/kT)1/2), which is typical for the tunnel mechanism of conductivity. Estimation of the sizes of metal granules from the values of the tunneling-activation energy C showed a good agreement with the sizes obtained earlier from the analysis of magnetic properties. In the dielectric range of the compositions, a giant magnetoresistive effect was obtained, reaching 25% at low temperatures.

AbstractThe element composition modification is experimentally studied in PZT thin films obtained via the RF magnetron sputtering with variable working gas pressure. The experimental data were interpreted through the statistic simulation of thermalization and diffusion of sprayed Pb, Zr, and Ti atoms during the ion-plasma deposition of PZT thin films. The simulation data are shown to adequately describe (within the limits of 5%) the change in element composition at various pressures of the gas environment. The study conducted enables one to produce PZT thin films with a set element composition, which is essential for optimizing the electric and physical properties of solid solutions at the morphotropic phase boundary.

AbstractThe effect of cyclic loading on the magnitude of coherent scattering regions (CSR) of X-ray radiation and microstresses of the II type in various crystalline materials: semiconductor (samarium sulfide) and metal (steel, duralumin) has been found. The loading was carried out by compressing the samples in various ways: all-round, uniaxial, bending compression. It is shown that with an increase in the number of compression cycles, the CSR values in all cases decrease, and the microstresses increase. These values can serve as parameters to assess the degree of mechanical fatigue of the material.
Анализ размерных эффектов при мартенситных переходах в эпитаксиальных пленках и микрочастицах сплава Ni-Mn-Sn

Abstract —The available literature data on the effect of the thickness of the epitaxial films and size of the crystallites in the microparticles of the Ni–Mn–Sn alloy powder on the parameters of the martensitic transitions in this alloy have been analyzed in the framework of the theory of defuse martensitic transitions (DMT), which is based on thermodynamic and kinetic ratios. The purpose of the analysis is to establish an explicit (functional) dependence of these parameters on the film thickness D and the size of nanocrystallites d in the film and microparticles. The results of the R-diffraction analysis show that internal elastic microdeformations and stresses arise in films and microparticles of the alloy powder due to the coherent coupling of the epitaxial film with a solid substrate or as a result of severe plastic deformation of the alloy during its grinding in a ball mill. The analysis shows that the local microstresses significantly affect the type of the dependence of the temperature interval (diffusity) Δ T of the transition on the size factors D or d . In the absence of microstresses, these dependences have the form Δ T ∼ 1/ D ^2 or Δ T ∼ 1/ d ^2. In the presence of microstresses, the temperature transition interval depends on the size factors as Δ T ∼ 1/ D or Δ T ∼ 1/ d .

AbstractThe growth rate and size of microcracks, formed in the surface layer of a heterogeneous natural solid (sandstone) under friction were studied via triboluminescence. It was discovered that destruction of the crystal lattice of plagioclase and quartz, composing sandstones, induces triboluminescence signals. Each s-ignal corresponds to a microcrack, whose surface contains electronically excited free radicals ≡Si–O^– and Fe^3+ ions. The size and growth rate of microcracks were assessed by means of analysis of the rate and duration of the buildup of these signals. The growth rate of microcracks turned out to be less than the elastic wave velocity (~700 m/s) and varied from ∼380 to ∼650 m/s. The size of microcracks varied from ∼4 to ∼7 μm. It was assumed that the variation in the size and growth rate of microcracks were caused by differences in value of the barriers, upon breaking which the microcracks appear.

AbstractIn this paper, we studied cobalt intercalation of single-layer graphene grown on the 4 H -SiC(0001) polytype. The experiments were carried out in situ under ultrahigh vacuum conditions by high energy resolution photoelectron spectroscopy using synchrotron radiation and low energy electron diffraction. The nominal thicknesses of the deposited cobalt layers varied in the range of 0.2–5 nm, while the sample temperature was varied from room temperature to 800°C. Unlike Fe films, the annealing of Co films deposited on graphene at room temperature is shown to not intercalate graphene by cobalt. The formation of the graphene–cobalt–SiC intercalation system was detected upon deposition of Co atoms on samples heated to temperatures of above ~400°C. Cobalt films with a thickness up to 2 nm under graphene are formed using this method, and they are shown to be magnetized along the surface at thicknesses of greater than 1.3 nm. Graphene intercalation by cobalt was found to be accompanied by the chemical interaction of Co atoms with silicon carbide leading to the synthesis of cobalt silicides. At temperatures of above 500°C, the growth of cobalt films under graphene is limited by the diffusion of Co atoms into the bulk of silicon carbide.

Steady-state field evaporation of tungsten at high temperatures (T ~ 2000 K) has been studied using a magnetic mass spectrometer equipped with the field ion source. Only low-charged ions (W+2 and W+) have been observed in the course of evaporation. The distribution of the ion currents by tungsten isotopes correspondents to standart isotopic ratio for natural tungsten. Some deviations from standart isotopic ratio were observed owing to fluctuations and unstable nature of evaporation process.

AbstractThe results of experiments and simulations of the transport of heat and particles in the Globus-M spherical tokamak are presented. Investigations were carried out in the ohmic mode in hydrogen and deuterium plasma. It is shown that in the phase of current growth under the same initial conditions, as long as the condition is met at which the minimum of the safety factor exceeds unity, two scenarios of discharge development are possible: with an electron temperature dive or with an electron density peak. After the safety factor reaches the value of 1, the differences are no longer observed. Modeling of transport processes using the ASTRA code showed that the dive of the electron temperature and density is a consequence of the decrease in the transport of heat and particles in the plasma core (i.e., the presence of internal transport barriers).

An Online Pain Education Program for Working Adults: Pilot Randomized Controlled Trial (Preprint)
Authors: Li Yajie , Tse Mun Yee Mimi
Published: June 2019

BACKGROUND

Pain is a common public health concern, and the pain situation among the general population is serious in mainland China. Working adults commonly experience pain because of long sitting times, a lack of free time, and exercise. A lack of pain-related knowledge is also a significant factor. Educational and therapeutic programs delivered online were used more often in Western countries, and accessible programs in China are limited, especially for pain management. Therefore, we carried out an online pain education program for working adults to self-manage pain. The program was delivered through WeChat, a popular and secure social media with a large population base in China.

OBJECTIVE

This study aimed to (1) provide pain-related knowledge and self-relief strategies, (2) help participants reduce pain and improve pain-related emotional well-being, and (3) explore participants’ learning performance and the acceptability of the online pain education program.

METHODS

This was a randomized controlled trial. Chinese adults aged between 16 and 60 years with full-time employment, with pain in the past 6 months, and without any mental illness were recruited using snowball sampling through the internet and were randomly allocated to an experimental group and a control group in 1:1 ratio after the baseline assessment. The 4-week educational program that included basic knowledge of pain, pharmacological and nonpharmacological treatments, and related resources was provided only to the experimental group. Outcomes of pain, depression, anxiety, stress, and pain self-efficacy were measured at baseline (T0), posttreatment (T1), and 1-month follow-up (T2). Participants’ acceptability and satisfaction were explored after completing the educational program.

RESULTS

In total, 95 eligible participants joined in the program: 47 in the experimental group and 48 in the control group. Neck and shoulder, head, and back were most commonly reported pain sites with high pain scores. Pain intensity and interference of the experimental group were significantly reduced after the educational program. Depression, anxiety, and stress clinically improved and pain self-efficacy improved after the educational program. The difference in depression, anxiety, stress, and pain self-efficacy within a group or between groups was not statistically significant; however, clinical improvements were demonstrated. A significant correlation between dosage of the intervention and pain intensity and depression was demonstrated. After completing the educational program, more than half of the participants showed acceptance of and satisfaction with the program, and they were willing to recommend the program to others.

CONCLUSIONS

Our findings highlight the significant potential of this online education program in the treatment of pain.

Incumbency Disadvantages and Populism in Indonesian Local Elections: Case Studies of Banda Aceh and Takalar
Authors: Nurlinah Nurlinah , Darwin Rizkika Lhena , Haryanto Haryanto
Published: June 2019

This article seeks to contribute an understanding of  how populism informs incumbency disadvantages in elections. Incumbency has been seen as highly beneficial in elections, and many studies have found that incumbent candidates enjoy significant access to resources with which they can campaign. This article, however, finds a different reality, with incumbents in Banda Aceh and Takalar experiencing electoral defeat. In both areas, extensive field studies before and after the local elections found that incumbents’ unwillingness to adopt a populist approach during their terms influenced voters’ choices. The main argument of this article is that, in Indonesia’s local democracies, incumbency has created space for varied models of  populism, including the communitarian populism found in Aceh and Takalar. Such populism has emerged from specific socio-cultural contexts at the local level that have shaped voters’ preferences. The socio-cultural context of  communal societies such as Aceh and Takalar has informed the truth value through which elites, policies, and phenomena are judged. Ultimately, this communitarian populism cannot be separated from the public’s desires for elections. These two cases offer a profile of  how communitarian societies respond to and shape local populism in Indonesia.
THE ROLE OF AUDIT AND CREDIT RATING AGENCIES IN THE ASSESSMENT OF COMPANY CREDITWORTHINESS WITH SPECIAL FOCUS ON BANKS
Authors: Jemović Mirjana , Đorđević Milica , Radojičić Jelena
Published: June 2019

Audit and credit rating agencies have a significant responsibility in assessing company creditworthiness and giving opinions on the client’s ability to continue business in the future, most often the next fiscal year. Responsibility is even greater when it comes to banks and their creditworthiness. The financial crisis of 2007 and the bankruptcy of a number of banks and other financial institutions imposed a need to seek accountability for the “delayed” reaction of regulatory bodies and significant fiscal consequences of the crisis. The aim of the paper is to evaluate the efficiency of credit rating agencies and external audit in assessing the creditworthiness of companies and banks, not for the purpose of finding their individual responsibilities, but to look at possible coordinated and joint actions to prevent future crisis events.

A group of universities have come together with the aim of designing and developing small aperture robotic telescopes (SmART) for use by students to observe variable stars and transient follow-ups. The group is deliberating on the components of the robotic system e.g. the telescope, the mount, the back-end camera, control software etc and their integration keeping in mind the scientific objectives. The Marburg group is
studying variable stars using photometric and spectroscopic observations in a small local observatory and via analysis of photo plate archival data mainly from Sonneberg observatory (Thuringa, Germany). Our goal is to setup a small, affordable observatory at Marburg University with full remote access to all components, including a spectrometer. Among others, the future measurements can be follow-ups, of variable stars, exoplanet search and spectroscopic measurements, e.g. in cooperation with the BRITE-constellation. We would like to invite other universities to join the project and cooperate in setting up a University network of small aperture robotic telescopes (U-SmART) around the globe.

Published: June 2019

Kopi Starbucks merupakan produk kopi yang menandakan nilai prestise yang tinggi bagi para penikmatnya karena harganya yang tergolong mahal. Bagi konsumen yang berpendapatan tinggi, tentu bukan hal yang sulit untuk mengonsumsi kopi Starbucks, namun bagi yang berpendapatan rendah mungkin akan berpikir ulang untuk mengonsumsi produk tersebut. Munculnya brand kopi ala Starbucks menunjukkan bahwa saat ini banyak animo masyarakat yang menginginkan kopi tetapi mereka juga melihat keadaan ekonomi mereka yang seutuhnya. Penelitian ini bertujuan untuk mengetahui pola pembentukan identitas yang dimunculkan oleh para konsumen pada produk imitasi ala Starbucks dengan memanfaatkan teori simulakrum dari Jean Baudrillard. Penelitian ini merupakan penelitian deskriptif kualitatif. Penelitian dilakukan di Kafe Starmug’s, Kelurahan Keputih, Kecamatan Sukolilo, Kota Surabaya. Sumber data penelitian yaitu hasil wawancara dengan berbagai informan yang merupakan beberapa orang pekerja dan juga mahasiswa di Surabaya yang disebut masyarakat urban. Penelitian ini menggunakan teknik pengumpulan data dengan observasi, wawancara, dan interpretasi. Analisis data dilakukan dengan mendeskripsikan dan memaknai data yang telah diperoleh. Hasil dari penelitian ini menunjukkan bahwa praktik konsumsi kopi ala Starbucks merupakan bentukan konsumerisme postmodern, yakni pola konsumsi yang tidak sesuai dengan arti harfiah dari konsumsi, namun lebih mengarah pada konsumsi simbol-simbol. Kata kunci: imitasi, konsumsi, kopi, posmodernisme, Starbucks.

Cholangiocarcinoma, malignant tumor of epithelial cells of bile ducts has poor overall survival and prognosis. We report a case of non-resectable cholangiocarcinoma with a 57-month survival after incomplete R2 surgical margin resection of the tumor. A 52-year old man with generalized itching, jaundice, brownish urine, mild abdominal pain and weight loss of 8 kg in last two months presented. Imaging and surgical workups showed hilar cholangiocarcinoma (Klatskin tumor). Along with incomplete R2 margin resection we performed stent embedding and post-operative adjuvant chemotherapy. Based on current literature data there is no superiority of adjuvant chemotherapy after complete R0 resection compared to incomplete R2 resection. However, it seems that partial resection along with stent embedding and applied adjuvant chemotherapy in cases of locally advanced non-resectable cholangiocarcinoma may increase survival rate.
Research on the effect of magnet parameters on the isochronous field of a superconducting cyclotron
Authors: Zhou Pengyan , Ding Kaizhong , Li Junjun , Xu Shiwen , Song Yuntao
Published: June 2019

It is a complicated task to obtain an isochronous field of a cyclotron magnet. Due to non-linear property of iron, iterated simulation of magnet design takes a long time to get an isochronous field. As an example, for a magnet design of a 240 MeV (SC240) superconducting cyclotron, the effect of main parameters of a magnet system on the magnetic field was studied, among them the azimuthal sector width, the spiral sector angle, the gap between sectors, the depth of valley region, the position of the coil, the shape of the coil and the excited current of the superconducting coil. It was found that the azimuthal average magnetic field can be increased by any of the following methods, including enlarging azimuthal width, increasing excited current of the superconducting coil, narrowing of the gap between sectors, reducing the depth of the valley region or decreasing the distance between the coil and the mid-plane. In addition, axial oscillation frequency can be improved by increasing the spiral angle, the depth of the valley region, or decreasing the gap between sectors.

Published: June 2019

In the paper, in a long-term test procedure, monocrystalline silicon cells were subjected to examination. Cells were tested in well-controlled laboratory conditions and real conditions. In laboratory conditions, white light of the artificial sun and monochromatic brightness of yellow sodium lamps were used. The testing was aimed at achieving the same aging regime in the laboratory conditions as in real conditions. This would allow for the laboratory aging algorithm of solar cells as in real conditions, to be defined, hence their working life of commercial exploitation in urban areas to be determined. By complex mathematical methods, i. e. using the theory of time duration, it was found that laboratory exposing solar cells to thermal neutrons causes their aging with the same mechanism as in real conditions.

Redefining the Indian Left: The AAP Way
Authors: Nath Dr. Abhishek
Published: June 2019

The spectacular success of BJP in the recent General Elections invited a mixed assessment from different positions. But mostly it was oversimplification and undermining of its success. On the other hand, the victory of AAP in assembly elections was taken as an alternative in making. For example along with other commenter’s in an article (published in The Indian Express, 26 May 2014, op-ed page) renowned lawyer and AAP leader Shri Shanti Bhushan analysed the electoral success of BJP and the future course for AAP that lacks in substance. It tried to under-assessed the BJP’s success and oversimplified the road ahead for AAP. As it like wait till BJP does the same blunders as Congress did. In this paper some light will be thrown on BJP’s success and legacy but will mainly discuss the AAP phenomena in Indian politics with a view to access the recent developments in party and as an emerging alternative that can also be an opportunity to capture the space vacated by the Left movement in India. First of all I would like to argue that considering the BJP after the failed Janta Party Experiment as a ‘faction of Janta Party’ (Shri Bhushan’s views) is not a correct judgment. Actually the Bhartiya Jan Sangha was the last party that remained as Janta Party coalition after the other four parties that came together without merging their distinctive identities to form Janta Party left the coalition at their will to pursue their own ambitions. Hence it was not just a matter of chance that the new party that emerged on the Indian political scene after the failed Janta experiment named Bhartiya Janta Party (Bhartiya Jana Sangha + Janta Party = Bhartiya Janta Party). The then leaders not only launched a new party with inheriting the name but also the legacy. As it was more moderate and reformed on many policy agendas by incorporating Gandhian- JP Legacy to fight against the ruling dispensation. That seed has now grown as a Banyan tree and shadowing the Indian political scene defying all ifs and buts. Although it is still to be tested that how will a full majority BJP will work in coming years as many scholars of Indian politics doubt the BJP’s course of action as a single full majority party (see Christophe Jaffrelot, 2003). It is also because the earlier BJP led government was a crippled and soft BJP as NDA coalition and also Atal Bihari Bajpai as its leader and was not able to pursue its core Hindutwa demands of building Ram temple, Uniform Civil Code and the abolition of Article 370 of the Constitution for the full merger of J&K into Indian Union.

Authors: Jack Daniel
Published: June 2019

This paper conceptualizes distinct conditions of the development store network (divided supply markets, prepare combination, work bunches, and pools of suppliers) as the consequence of crossing two vital measurements: modern "modes" (i.e. from venture to prepare) and the degree of incorporation in which association exists (i.e. from less to very coordinated inventory network). Change approaches, for example, TQM and incline thinking give administration logic, strategies and instruments to enhance the execution of the development inventory network towards its "optimal" practice (esteem creation). Since benchmarking is an essential component for overseeing execution in the development business, the on-screen characters in a development inventory network need to recognize and create applicable esteem related (execution) measures and their effects on picking up/keeping up accomplices' trust and their ability to work together.

Punam V. Barbde is an Assistant Professor in Amravati.  She chose to research on Arun Joshi’s novel, The Foreigner.  I think she chose this topic for her research because it is a hot burning issue in our society where everybody is restless, impatient and agitative.  People have become more and more materialist and selfish.  This trauma, agony, pain and sufferings is explored in the novel, The Foreigner.

 

In the modern life globalization and modernization, we people have become so self-centered, selfish and egoistic that the important ingredients of being a human-being is left far behind.  Ingredients of sympathy, kindness, love, care, and sensitivity is becoming a rare-found species.

Money, materialism and me dominates on human minds so much that there is chaos, confusion, and restlessness all over the place.

Line balancing is to distribute the task over the each workstation so that idle time of labor of machine can be minimized. Line balancing aims at grouping the resources or labor in an efficient and best pattern in order to obtain an optimum or proper balance of the resources and flows of the production or assembly processes. Assembly Line Balancing (ALB) is the term commonly used to refer to the decision process of assigning tasks to workstations in a sequential way to the production system. The task of elementary operations required to build raw material into a finished product.

Line Balancing is a classic Operations Research optimization technique which has significant industrial importance in a lean system. The concept of mass production essentially involves the Line Balancing in assembly of identical or interchangeable parts or components into the final product in various stages at different workstations. With the improvement in knowledge, the refinement in the application of the line balancing procedure is also a must. Task allocation of each worker was achieved by assembly line balancing to increase an assembly efficiency and productivity. In this paper, we discuss and analysis a vehicle manufacturing unit and suggest the options to increase the productivity through an assembly line balancing with the help of Pro Balance.

Authors: , PANKAJ
Published: June 2019

A wireless sensor network (WSN) is a spatially distributed autonomous sensor to monitor and cooperatively report information about physical or environmental conditions, such as temperature, sound, pressure, etc. through the network to a server machine. WSNs are typically enforced for assembling data from insecure surroundings. Nearly all security protocols for WSN believe that the unwelcome person is able to do entirely management over a detector node by manner of direct physical access. The looks of detector networks together of the most technology within the future has display numerous challenges to researchers. The challenges thrown by WSNs are distinctive given their delicate design and scant resources. Even supposing security for wireless networks has been a wide researched space for several decades, security for WSNs continues to be a serious roadblock for his or her potency and performance.
“Enhanced Tomato plant growth in presence of a novel microbial consortia useful in bio-organic waste degradation-A pilot level field study”
Authors: Nalla Vijay Kumar
Published: June 2019

Sustainable use of natural resources and reuse of wastes has become an important global concern which promotes the efficiency of ecological system and promotes health by decreasing disease transmission and can contribute to increase in agricultural yield. In underdeveloped and developing countries, mal nutrition constitutes approximately 14% of global burden of disease, which supersedes the sanitation related disease, which is only 3.4% (Lopez et al., 2006). Human wastes contain millions of tons of fertilizer equivalents, which is roughly 20% to 30% of global industrial fertilizer production, annually (Winker et al., 2009). To main agricultural yields at high levels over the years, the nutrients removed by crops have to be replaced. For example, urine is rich in nitrogen, which is most limiting nutrient for plant growth while feces are rich in phosphorous, potassium and recalcitrant organic matter which can give substantial yield, especially on poor soil (Jonsson et al., 2004). This data reflects the urgent need of sustainable technologies of developing the agricultural practices towards improving the nutrient quality of foods. Hence, the developing nations like India are in great need of sustainable reuse oriented sanitational technologies, which prevent disease and promote health. Hence, the current research focusses on developing a sustainable technology which is microbial based conversion of human and animal excrements into agriculturally useful organic manure.

Authors: Esina Lyubov Mikhailovna , Bogomolova Valeriia Victorovna , Krivonos Olga Nikolaevna , Chernyavskaya Svetlana Leonidovna
Published: June 2019

Pipelines, mechanisms and hydraulic structures laid on the bottom of freshwater bodies are exposed to massive exposure of fouling organisms - mollusks Dreissena polymorpha . Such fouling hinders the equipment operation and increases the corrosion of materials, besides, utilization of mollusks ( Dreissena polymorpha ) requires financial expenditure. Therefore, to solve the problem, dreissena was suggested to be used as a raw material for producing enzymatic hydrolyzate. The data of the mass-size and chemical composition of the raw materials (dreissena flesh) are presented. During the analysis of the model of a 2-factor experiment (the amount of enzyme preparation and the duration of fermentolysis were taken as factors) there was defined the optimal amount of enzyme (bacterial protease - protozyme). The comparative analysis of a control sample (without adding the enzyme) and enzymatic hydrolyzates of dreissena was carried out. There was stated the increase in protein content (3.7-17.8%), in dry matter (7.0-22.7%), amine nitrogen (446.2-158.6 mg/100 g). The periods of the most intensive increase in the degree of hydrolysis (during the first 2 hours of enzymatic hydrolysis by 2.8% and further 3-4 hours by 1.2%), as well as periods of values stabilization (during 2-3 hours and after 4 hours of enzymatic hydrolysis an increase by 0.6% on average). The change in the optical density of hydrolyzate solutions and their TCA-filtrates has been studied, which helped to compare the degree of protein destruction. There has been presented the technological chart of producing enzymatic hydrolyzates from dreissena with following conditions for fermentolysis: temperature 50 ºС, water ratio 1:1, quantity of enzyme protozyme 0.1% to the mass of blanched dreissena with valves, duration 3-4 hours.

The paper presents the assessment results of the influence of hydrological conditions on the qualitative characteristics of bream juveniles in the Volga delta. The influence of factors (volume, hydrological characteristics of spring flood, temperature conditions) on the spawning periods of producers, duration of feeding of juveniles at spawning grounds, including viable ones, at the end of the hollow period has been traced. There have been presented the comparative data on the age, distribution and qualitative composition of larvae and juveniles obtained in the course of the research works at spawning grounds in different regions of the lower reaches of the Volga River in 2011-2017. The most favorable conditions for feeding on young bream have been found to form in the high-water years (2013 and 2016) and in the mid-water year (2017). Years 2011 and 2015 became critical for natural reproduction; years 2012 and 2014 were unfavorable. The highest size-weight characteristics of bream juveniles were observed by the end of the hollow period in the east of the delta in the arid and middle water years, and in high-water years they were found in the Volga-Akhtuba floodplain. The qualitative characteristics of bream in the east in low-water years were maximum in the upper zone, minimal - in the middle zone, in the western spawning grounds there was observed a reverse situation. In high-water years the highest values of bream juvenile size-weight parameters were observed in the middle zone in the east of the delta. In the mid-water year (2017) in the eastern part of the delta the maximum feeding results were observed in the lower zone, and in the spawning grounds of the western delta - in the middle zone. By the end of the feeding period in high-water years practically all bream juveniles (98.4%) reached the viable stage of development, and in arid years only 28.4% of bream juveniles reached the stage.
