Purpose: based on long-term data on the dynamics of fish catches and foreign trade in fish products, as well as international comparisons of world fishing powers, analyze the prospects for the development of the domestic fishing industry in the new economic conditions of sanctions confrontation with the countries of the collective West.Method: used such methods of general scientific knowledge as analysis and synthesis, as well as comparisons, tabular and graphical methods.Novelty: a detailed assessment of the factors affecting the growth of domestic fishing and fish farming, including the development of the domestic fishing fleet, was made. The prospects for expanding the sale of fish products on world markets, including on the basis of data on current and prospective consumption in different regions of the world, were considered.Results: the study analyzed a number of sources, including FAOSTAT and Rosstat commodity resource balances, in terms of production, consumption and cross-border trade in fish products. It has been established that after 2014 own consumption and imports are declining, while exports, on the contrary, are gradually increasing. Thus, the main driver of production growth in the industry is expansion to foreign markets. In the context of strengthening anti-Russian sanctions policy, it is necessary to diversify the sales markets for Russian fish products, however, an outdated production base is a significant limitation for the development of the industry.

The aim of the work is to determine the influence of sea water circulation and temperature on the formation of the spawning stock of anchovy in the Sea of Azov.Materials and methods: Fishery and biological data on the spawning stock of the Azov anchovy were collected in surveys and bioresources monitoring carried out by the Azov-Black Sea branch of the VNIRO («AzNIIRKH») in 2000–2021. Satellite sea level data were used in the analysis of sea water circulation. These data, as well as satellite information on sea surface temperature for March-June 2000–2021 for the north-eastern part of the Black Sea and the southern part of the Azov Sea were taken from the website of the Copernicus Marine Service information system. Graphical and statistical methods of analyzing multi-year changes in the data were used in the work. The novelty of the performed work lies in the study of oceanographic conditions of spring migration of anchovy to the Sea of Azov as factors determining the size of its spawning stock in this sea.Result: intensive growth of the spawning stock of anchovy in the Sea of Azov was observed in 2008, 2010 and 2011. This was facilitated by: predominance of north-western geostrophic currents in the north-eastern part of the Black Sea in April 2008–2011, weakening of the Azov currents in the Kerch Strait in April 2007–2010 and predominance of the Black Sea currents in May 2004–2012, Decrease in the meridional gradient of water temperature in the Kerch Strait in April 2007–2010.Practical significance: the possibility of using oceanographic information for April-May to predict the size of the spawning and commercial stock of anchovy in the Sea of Azov.

The requirement of water for plants absolutely must be realized hence, it is necessary to make efforts in order to plants can still provide their water needs even though the availability of water for watering is less or even not available continuously. This study was conducted to evaluate the effect of water application and zeba products on the growth of oil palm seedlings in the main nursery. The study arranged as a randomized completely block design (RCBD) with 5 treatments: without Zeba with 2 times watering; without Zeba with 1 time watering; Zeba 10 g/polybag with 1 time watering; Zeba 20 g/polybag with 1 time watering and Zeba 20 g + Rock Phosphate 75 g with 1 time watering. Watering is carried out in accordance with the treatment at the time from 07.00-09.00 WIB in the morning and 16.00-18.00 WIB in the afternoon using a paddle with a volume of 2 liters of water. There were three replications for each treatment. Variables observed plant height, stem diameter, leaf number, leaf color, soil pH values. The results showed that Zeba application affects the height of oil palm seedlings in the main nursery, stem diameter, soil pH and leaf color, but does not affect the number of leaves. Twenty grams of zeba on soil showed the similar response of stem diameter, soil pH and leaf green color with 20 g zeba + Rock Phosphate fertilizer. Zeba application can save water use in the main nursery of oil palm plants

REVISÃO DE LITERATURA

RESUMO
As complicações associadas à cirurgia de implantes dentários podem afetar significativamente tanto o tratamento quanto o conforto do paciente. As mais frequentes incluem infecção, que pode evoluir para peri-implantite, uma inflamação dos tecidos ao redor do implante que, se não tratada, pode levar à sua perda. Outra complicação é a falha na osseointegração, o processo de união do implante ao osso, que pode ser influenciada por fatores como a qualidade óssea, a técnica cirúrgica, o estado geral de saúde e os hábitos do paciente. A persistência de dor pode ser um indicativo de infecção ou falha na osseointegração. Além disso, danos a nervos ou vasos sanguíneos durante a cirurgia podem resultar em parestesia, hematomas ou sangramentos excessivos. A taxa de insucesso dos implantes varia de 1,5% a 10%, acarretando em maior tempo de tratamento, custos adicionais, desconforto ao paciente e, potencialmente, constrangimento para o profissional. O fracasso do implante está associado à condição sistêmica e local do paciente, aos seus hábitos, além das condições cirúrgicas e protéticas. As causas do insucesso são multifatoriais e incluem desde a seleção inadequada do material, erros de planejamento, falhas na fabricação ou instalação do implante, até problemas na reparação óssea, além de complicações técnicas, como perda da retenção protética, fraturas da estrutura ou do material de revestimento estético, e afrouxamento ou fratura do parafuso protético.

<p><em> </em><strong>PT. PLN Nusantara Power UP Tenayan is a company operating in the power generation sector and focuses on operating PLTUs Tenayan, Indonesia. One part of the machine that influences the operation of the generator is the boiler feed pump. Lack of optimal boiler feed pump instrumentation often results in failure in operating activities. This research uses the Failure Mode and Effect Analysis (FMEA) method with the research objective of finding out the causes of failures that occur, identifying the type of failure, and determining the RPN value and the impact that occurs. The analysis results, it shows that the Boiler Feed Pump instrumentation components still meet operating standards because the Risk Priority Number (RPN) value is below 200, even though the Speed Sensor has a fairly high RPN value but is still in the reliable category, the result of identifying the type of failure that occurs is that the indicator reading is not actual, the component is not functioning, the highest RPN value for the Boiler Feed Pump component is the Speed Sensor component with an RPN value of 160 and the lowest RPN value is for the pressure indicator component with an RPN value of 30. The most important recommended action for the Speed Sensor component is to carry out maintenance for 1 month very.</strong></p><p><strong><em>Keywords</em></strong> – <em>Boiler Feed Pump, FMEA, Keandalan, Pembangkit, RPN.</em></p>

Published: October 2024

Abstract
Deriving high-quality light curves for asteroids and other periodic sources from survey data is challenging owing to many factors, including the sparsely sampled observational record and diurnal aliasing, which is a signature imparted into the periodic signal of a source that is a function of the observing schedule of ground-based telescopes. In this paper we examine the utility of combining asteroid observational records from the Zwicky Transient Facility and the Transiting Exoplanet Survey Satellite, which are the ground- and space-based facilities, respectively, to determine to what degree the data from the space-based facility can suppress diurnal aliases. Furthermore, we examine several optimizations that are used to derive the rotation periods of asteroids, which we then compare to the reported rotation periods in the literature. Through this analysis we find that we can reliably derive the rotation periods for ∼85% of our sample of 222 objects that are also reported in the literature and that the remaining ∼15% are difficult to reliably derive, as many are asteroids that are insufficiently elongated, which produces a light curve with an insufficient amplitude and, consequently, an incorrect rotation period. We also investigate a binary classification method that biases against reporting incorrect rotation periods. We conclude the paper by assessing the utility of using other ground- or space-based facilities as companion telescopes to the forthcoming Rubin Observatory.
X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA

Published: October 2024

Abstract
Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass galaxies may retain memory of the assembly history of their black holes (BHs), probing the BH occupation fraction of local dwarf galaxies might offer insights into the growth and seeding mechanisms of the first BHs. In this work, we exploit the Western half of the eROSITA all-sky survey (covering 20,000 deg2) and compile a catalog of accreting SMBHs in local (D < 200 Mpc) dwarf galaxies. Cleaning our sample from X-ray background sources, X-ray binaries, and ultraluminous X-ray sources, we identify 74 active galactic nucleus (AGN)–dwarf galaxy pairs. Using this large and uniform sample, we derive the luminosity function of the dwarf galaxy AGN, fitting it with a power-law function and obtaining

. Measuring the offset between the dwarf galaxies' centroids and the X-ray sources, we find that ≈50% of the AGN are likely off-nuclear, in agreement with theoretical predictions. We compare the BH-to-stellar mass relation of our sample with the local and high-redshift relations, finding that our sources better adhere to the former, which suggests that local AGN across different mass scales undergo similar growth histories. Finally, we compare our sources with semianalytical models: while our sample’s shallowness prevents distinguishing between different seeding models, we find that the data favor models that keep SMBHs in dwarf galaxies active at a moderate rate, motivating model improvement by comparison to AGN in the dwarf galaxy regime.
The Bulk Densities of Small Solar System Bodies as a Probe of Planetesimal Formation
Authors: Tatsuuma Misako , Kataoka Akimasa , Tanaka Hidekazu , Guillot Tristan 
Published: October 2024

Abstract
Constraining the formation processes of small solar system bodies is crucial for gaining insights into planetesimal formation. Their bulk densities, determined by their compressive strengths, offer valuable information about their formation history. In this paper, we utilize a formulation of the compressive strength of dust aggregates obtained from dust N-body simulations to establish the relation between the bulk density and diameter. We find that this relation can be effectively approximated by a polytrope with an index of 0.5, coupled with a formulation of the compressive strength of dust aggregates. The lowest-density trans-Neptunian objects (TNOs) and main-belt asteroids (MBAs) are well reproduced by dust aggregates composed of 0.1 μm sized grains. However, most TNOs, MBAs, comets, and near-Earth asteroids (NEAs) exhibit higher densities, suggesting the influence of compaction mechanisms such as collision, dust grain disruption, sintering, or melting, leading to further growth. We speculate that there are two potential formation paths for small solar system bodies. One involves the direct coagulation of primordial dust grains, resulting in the formation of first-generation planetesimals, including the lowest-density TNOs, MBAs, and the parent bodies of comets and NEAs. In this case, comets and NEAs are fragments or rubble piles of first-generation planetesimals, and the objects themselves or the rubble are composed of 0.1 μm sized grains. The other path involves the further potential fragmentation of first-generation planetesimals into the compact dust aggregates observed in protoplanetary disks, resulting in the formation of second-generation planetesimals composed of compact dust aggregates, which may contribute to explaining another formation process of comets and NEAs.
Signatures of Mass Segregation from Competitive Accretion and Monolithic Collapse
Authors: Parker Richard J. , Pinson Emily J. , Alcock Hayley L. , Dale James E. 
Published: October 2024

Abstract
The two main competing theories proposed to explain the formation of massive (>10 M
⊙) stars—competitive accretion and monolithic core collapse—make different observable predictions for the environment of the massive stars during, and immediately after, their formation. Proponents of competitive accretion have long predicted that the most massive stars should have a different spatial distribution to lower-mass stars, through the stars being either mass segregated or being in areas of higher relative densities or sitting deeper in gravitational potential wells. We test these predictions by analyzing a suite of smoothed-particle hydrodynamics simulations where star clusters form massive stars via competitive accretion with and without feedback. We find that the most massive stars have higher relative densities, and sit in deeper potential wells, only in simulations in which feedback is not present. When feedback is included, only half of the simulations have the massive stars residing in deeper potential wells, and there are no other distinguishing signals in their spatial distributions. Intriguingly, in our simple models for monolithic core collapse, the massive stars may also end up in deeper potential wells because if massive cores fragment then the stars that form are also massive, and dominate their local environs. We find no robust diagnostic test in the spatial distributions of massive stars that can distinguish their formation mechanisms, and so other predictions for distinguishing between competitive accretion and monolithic collapse are required.
