Introduction:
This study seeks to provide insights into the current state of vascular access education in adult nephrology fellowship programs in the United States and to identify areas for improvement.

Methods:
A total of 63 adult nephrology programs and 71 second-year adult nephrology fellows were randomly selected for participation in a roundtable. Virtual roundtable discussions preceded by a survey were conducted to gather information on the delivery of vascular access education. Descriptive statistics were employed for analysis.

Results:
Among the respondents invited to the roundtable discussions, 42 individuals (30 faculty, 12 fellows) completed the survey, while 21 individuals (13 faculty, 8 fellows) also participated in the roundtable discussion. Of these respondents, a majority (67%) of didactic lectures on vascular access in fellowship programs were delivered by general nephrologists, with 57% provided by interventional nephrologists, 36% by surgeons and 17% by interventional radiologists (respondents were able to select multiple disciplines). The respondents reported limited exposure to proceduralists, including interventional nephrologists and vascular access surgeons during fellowship training. Faculty and fellows were less comfortable with physical examination skills related to vascular access, particularly in using point-of-care ultrasound and interpreting vascular imaging as compared to naming and identification of vascular access. Both groups emphasized the importance of hands-on modalities in vascular access education.

Themes and Recommendations:
Roundtable discussions highlighted the need for enhanced hands-on training, multidisciplinary collaboration, and standardized curricula in vascular access education. Recommendations were formulated in alignment with the three levels of competency outlined by the American Society of Nephrology (ASN) Task Force on the Future of Nephrology, aiming to address gaps and improve the quality of vascular access education in nephrology fellowship programs.

Conclusion:
This study underscores the importance and need for a comprehensive vascular access education in nephrology fellowship training. By implementing the identified recommendations, programs can better prepare fellows to manage vascular access-related challenges in clinical practice.

Abstrak
Poligami adalah keniscayaan yang harus diterima oleh setiap personal yang berpegang teguh pada tali agama Allah yakni islam. Islam mengatur persoalan poligami dengan sangat detail, untuk menjaga keseimbangan, keadilan, keteraturan dan menghindari kesewenang-wenangan. Syariat tentang poligami turun dengan membawa semangat mengurangi kuantitas bukan sebaliknya, melalui mekanisme persyaratan yang sangat ketat yakni, keadilan. Berbeda dengan kebudayaan jahiliyah yang melegalkan laki-laki menikah tanpa batasan jumlah istri, islam membatasi seorang laki-laki menikah hanya dengan maksimal 4 orang saja. selain itu islam juga memberikan hak yang sama bagi perempuan atau walinya untuk menerima atau menolak dipoligami sumainya. Sebagimana Nabi SAW melarang Ali Bin Abi Thalib menikahi wanita lain kalau masih dalam ikatan perkawinan bersama putri kesangannya Fatimah. Metodologi penelitian ini menggunakan pendekatan kualitatif dengan jenis eksploratif. Penelitian ini akan megkaji dua hal, pertama, analisis batasan poligami dalam perspektif hukum fiqih dan KHI. Kedua, hak perempuan menolak poligami. Adapun hasil dari penelitian ini adalah pertama, poligami disyariatkan diatas nilai maslahah untuk itu, agama memberikan hak bagi istri untuk menerima atau menolak dipoligami.

Published: February 2025

Abstract
In the current energy crisis, the focus on identifying ecosustainable solutions for the construction industry is growing significantly. The materials used, the assembly technologies and the labor force are the main costs that are found in the final price of a new construction or in the rehabilitation of the old buildings. However, the interest in reducing costs must be accompanied equally by the concern to reduce the impact of human activities on natural ecosystems. The paper presents a possible technical solution for making leveling screeds based on biodegradable plant material obtained from the stem of the hemp. Two variants of making the leveling screed using hemp shive as the basic material are presented. The results obtained were compared with two current variants of pouring the leveling screed, such as pearlitic screeds or expanded clay screeds. The aim is to provide technical information verified by laboratory tests to change the perspective on construction materials obtained from vegetable waste.

Abstract
The present study focuses on the sustainable solution for the improvement of expansive soils behavior using scrap tyre rubber. With the alarming increase of tyre wastes, the researchers world-wide are looking for sustainable methods to include all types of scrap tyre materials in civil engineering structures. This type of waste is very hard to dispose and its clearly unwanted in any kind of urban-industry. Expansive soils are well known for their problematic behavior and have always caused geotechnical problems causing different types of structural damage at light weight buildings and roads. The expansive soil used in this experimental study is the Bahlui Clay which is analyzed in various conditions and in different mixtures with the waste tyre crumbs. In the laboratory tests different percentages of scrap tyre crumbs along with rubber powder have been used aiming to see some improvements of physical parameters. Results have shown that the waste tyre crumbs can be used as a method of soil stabilization, but only in certain conditions. The 30% scrap tyre addition proved to have a positive influence on the geotechnical properties of the active clay, improving the physical soil parameters such as Atterberg limits, linear contraction, and plasticity index.

Published: February 2025

Abstract
The concept of energy is closely related to the building sector and the systems used for heating, implicitly energy saving which is a current problem of both old and new buildings. In this paper a series of numerical simulations were made in Autodesk CFD Simulation in order to study the influence of terminal heating systems over the thermal comfort in rooms. Three case solutions were analysed, as follows: heating a room using a steel radiator, heating a room using an aluminium radiator and heating a room using underfloor heating. The values resulted through numerical simulations for the average room temperature were compared with the values for ideal heating. It was observed that underfloor heating is the most efficient source of heating among those analysed. Compared to heating using radiators, the temperatures along the length and height of the room using underfloor heating are constant and close to the ideal heating. The human body feels the most comfortable due to the uniform distribution of temperature from ground level, on height.

Abstract
With a view to sustainable development, the safe supply of natural gas necessary for food preparation and home heating is a priority issue.
The natural gas industry is a competitive market that requires high-performing assets that can be translated into high operational availability, production efficiency, reliability, and maintainability of all assets.
The quality of natural gas supply systems is the basic indicator of the economical energy industry. Reliability being, along with other technical and economic indicators, is a component of quality, it must be in the attention of all the factors that determine the good running of the company.
Following the technological developments in the field of plastics, in the last decades, the pipes made of polyethylene are more and more frequently used in the realization of the natural gas distribution systems.
The use of high-density polyethylene pipes is due to the fact that the service life, corrosion resistance, flexibility, and resistance to dynamic stress are superior to steel pipes.
However, this material also has some disadvantages.
High-density polyethylene pipe is easily affected by ultraviolet light. In addition, the mechanical strength of high-density polyethylene pipe is lower than that of steel.
Due to the increase in the number of vehicles in urban areas and the degradation of asphalt on roads, the rate of damage to polyethylene pipes has increased rapidly.
In view of the problems encountered in the operation of high-density polyethylene pipes installed underground in the roadway, an analysis of these problems is necessary.
This type of analysis is based on the assumption that pavements are subjected to static loads and that paving materials, supports, and pipes are linearly elastic materials. In reality, the pavements are subjected to both static and dynamic loads, the asphalt mixtures are viscoelastic materials, and the clays have plasticity. So, for simplicity, static loads are applied on a road section with properties of linear elastic material.
The paper deals, by numerical methods (finite element method), with the deformation modulus and the stress state of high-density polyethylene pipes subjected to the loads resulting from the movement of vehicles on an asphalt road.
This paper examined the application of QuickField software on an asphalt pavement at different vehicle positions and the responses of high-density polyethylene pipes to these loads.
These analyzes help to position high-density polyethylene pipes in the roadway directly from the design.
The Relationships Between Environmental Regulation and Eco-Efficiency: Evidence from China
Authors: Chu Xuyuan 
Published: February 2025

Abstract
This study explores the causal relationships between environmental regulation and eco-efficiency in China’s industrial and power sectors using a vector autoregressive (VAR) model and Granger causality tests. By analysing data from 2006 to 2020, we find that energy structure plays a pivotal role in determining eco-efficiency within the industrial sector, while imperative environmental regulations are a significant Granger cause of eco-efficiency in the power sector. Industrial agglomeration also exerts notable effects in both sectors. These findings underscore the sector-specific differences in the effectiveness of environmental regulations and highlight the need for tailored policy approaches to improve eco-efficiency across industries.

Abstract
By decision of voters, the local government of the new term was elected in 2024. The study conducted in the largest Polish urban centres allowed to characterize single-person executive bodies of municipalities, taking into account both political and demographic criteria. The tendency to mask signs was confirmed. The level of social support for the winning candidates responsible for managing local administration for the next five years was also determined. The analysis covered all cities with district rights, whose total revenues reached 18% of the state budget revenues in the analysed period. 66 mayors who managed municipal employees and performed corporate supervision over municipal institutions, units and companies had the actual impact on the spending of these funds. Describing the single-person executive bodies of all Polish cities with district rights, elected in the elections in April 2024, was the purpose of the paper. The conducted research study allowed to characterize (taking into account both political and sociological criteria) a group of 66 mayors managing the largest centres of local government in Poland. The paper was based on the analysis of source materials from the National Electoral Commission, data provided by the Central Statistical Office, budget resolutions adopted by collegial decision-making bodies of cities with district rights, as well as media verification of texts published in the mass media and social media.

Влияние удобрений на содержание фотосинтезирующих пигментов в ассимилирующих органах голубики на рекультивируемом участке торфяного месторождения в Беларуси
Authors: ЯРОЩУК А.А. 
Published: February 2025

Приведены результаты сравнительного исследования в опытной культуре на рекультивируемом участке выбывшего из промышленной эксплуатации торфяного месторождения верхового типа на севере Беларуси влияния полного минерального и отечественных микробных удобрений МаКлоР, АгроМик и Бактопин на состояние пигментного фонда хлоропластов ассимилирующих органов V. angustifolium и сортов V. corymbosum Northblue и Northcountry. Установлена его существенная трансформация, имевшая наиболее выраженный характер у сорта Northblue. При этом у V. angustifolium незначительное стимулирующее действие на накопление пигментов оказывало только внесение Бактопина, АгроМика и особенно 50ного МаКлоРа. Наиболее эффективным в плане активизации биосинтеза фотосинтезирующих пигментов для сорта Northcountry было внесение 10ного МаКлоРа и N16P16K16. Все остальные агроприемы, особенно применение 50ного МаКлоРа, способствовали обеднению пигментного фонда его ассимилирующих органов на 149270, по сравнению с контролем. Для сорта Northblue показано максимальное в эксперименте стимулирующее действие на биосинтез фотосинтезирующих пигментов всех без исключения испытываемых агроприемов, особенно внесения N16P16K16, при расхождении степени их максимального и минимального позитивного влияния в 6,7 раза. При этом в ряду микробных удобрений наиболее эффективным было использование препарата МаКлоР, тогда как наименее результативным внесение АгроМика и Бактопина.
The results of a comparative study in an experimental culture on a reclaimed site of a toptype peat deposit in north of Belarus, the influence of the complete mineral and domestic microbial fertilizers MaKloR, AgroMik and Bactopin on the state of the pigment fund of chloroplasts of assimilating organs V. angustifolium and varieties V. corymbosum Northblue . Its signifi cant transformation, which had the most pronounced character in the Northblue variety, was established. At the same time, in V. angustifolium, insignificant stimulating effect on the accumulation of pigments was exerted only by the introduction of Bactopin, AgroMik, and especially 50 MaKloR. The most eff ective in terms of enhancing the biosynthesis of photosynthetic pigments for the Northcountry variety was the introduction of 10 MaKloR and N16P16K16. All other agricultural methods, especially the use of 50 MaKloR, contributed to the depletion of the pigment fund of assimilating organs by 149270 , compared with the control. For the Northblue variety, the experimentally stimulating effect on the photosynthetic pigment biosynthesis of all agroreceptions tested without exception, especially the application of N16P16K16, was shown, with a difference of 6,7 times the degree of their maximum and minimum positive influence. At the same time, in the range of microbial fertilizers, the most effective was the use of the drug MaKlor, while the least effective was the use of AgroMik and Bactopin.

The authors analyzed the current state of mining areas and evaluated the evolution of environmental components after the cessation of anthropogenic impact using remote sensing methods, revealed the nature of the spread of pollutants in mining areas and factors affecting this distribution, as well as the state of vegetation. The use of remote sensing methods and technologies of GIS sensing enabled the authors to clarify the migration routes and the nature of pollutants from decommissioning tailings. An assessment was made of the process of natural restoration of waste mining sites. The state of vegetation can be considered as an indicator of the level of technogenic load on the natural environment of the study area. Restoration of vegetation characteristics by means of remote sensing data allows one to obtain some numerical characteristics of the biomass volume, which can serve as an indicator of the restoration of disturbed lands. The article clearly shows the use of the results of remote sensing of natural and manmade situations in mining areas in solving environmental problems. The optimal combinations of Landsat satellite spectral bands for the synthesis of color images that solve various problems were selected. It has been determined that vegetation is sensitive to environmental disturbances and clearly reflects the change in the ecological situation as a result of anthropogenic impact.

Представлены результаты изучения каналов периферического разрушения более 600 типов частиц с барионным зарядом >1 (d, t, …, 55K,…) ядерного каскада, порождаемого релятивистскими ионами. Предложено выражение для энергетически выгодных каналов полного расщепления таких частиц. Показано преимущественное образование фрагментов с электрическим зарядом <3, подтверждаемое экспериментальными данными. Отмечено, что подобная деградация спектра масс частиц способствует повышению эффективности ядерно-каскадного варианта электроядерного направления энергогенерации и утилизации промышленных отходов.
The results of studying the channels of peripheral destruction of more than 600 types of particles with a baryon charge >1 (d, t, ..., 55K,...) of the nuclear cascade generated by relativistic ions are presented. An expression for energy-efficient channels of complete splitting of such particles is proposed. The predominant formation of fragments with an electric charge <3, confirmed by experimental data, is shown. It is noted that such degradation of the mass spectrum of particles contributes to the efficiency of the nuclear cascade version of the electro-nuclear direction of energy generation and disposal of industrial waste.
