Authors: Şoldan Bianca-Roxana Sălăgeanu , Bejinaru Ruxandra 
Published: March 2024

Abstract
This research paper aims to identify the factors, components, and key aspects that significantly contribute to the establishment of a sustainable business ecosystem through a comprehensive bibliometric analysis. By analysing prominent publications, we seek to describe coherent strategies with an expected impact. Our objectives encompass exploring trends from both theoretical perspectives, such as predictions by scientists, and empirical perspectives, including figures derived from studies. We outline several secondary objectives that guide our step-by-step approach. Firstly, we identify defining elements of a sustainable business environment based on insights from specialized literature. Secondly, we categorize ecosystems into different types, such as economic, digital, ecological, and entrepreneurial, providing further elaboration later in the paper. Thirdly, we present an updated understanding of the dynamic evolution of ecosystems and their components. This includes examining the influence of digital advancements and digitalization on the business environment, as well as the opportunities and threats they generate. Of particular importance is the role of universities as a significant landmark within the business ecosystem. We discuss the university's involvement in technological and informational transfer to ensure sustainability, focusing on the levers through which universities consolidate and stimulate the business ecosystem. To achieve our objectives, we employ bibliometric analysis, utilizing the VOSviewer software, which offers valuable insights for constructing diagnostic schemes and development models tailored to specific business environment challenges. The research methodology relies on the VOSviewer software for processing academic publication databases. To align with the theme and purpose of this study, we selected the SCOPUS database for its implicit certification of superior academic quality in the publications it contains.
The Dynamic Effect of Financial Sector Development in Stimulating the Gross National Savings of Djibouti
Authors: Dirir Sadik Aden , Aden Kadir 
Published: March 2024

Abstract
Savings are important determinants of wealth. At the macroeconomic level, governments attach importance to saving money in order to make new investments, produce new capital goods, and sustain economic growth. However, due to the high level of internal and external debt in Djibouti, it is nearly impossible for the country to achieve domestic savings. Hereby, the major aim of this study is to examine the dynamic effect of financial sector development in stimulating the gross national saving of Djibouti from the period 1987 to 2021. The paper considered numerous indicators as measurements of the financial sector development including FDI inflows, domestic loans to the private sector, central bank assets to GDP, and money supply. To proceed with the analysis, Non-Linear Autoregressive Distributed Lag (NARDL) was performed and according to the model, the findings highlighted that the Djiboutian financial industry is still in its early development and has not yet made a substantial contribution to boosting the country’s national savings. Nevertheless, the gross national saving of Djibouti was still positively prompted by significant components of the financial sector development, such as the positive shocks of FDI inflows and both the negative shocks of central bank assets and money supply. While both the positive and negative shocks of the credit offered to the private sector were uncovered to diminish the national savings in the long run. In conclusion, the current research will help governments and policymakers understand the best ways to use the financial sector to raise gross national savings. It will also present evidence of how to implement long-term initiatives that can lower public debt and encourage savings. Not to mention, the article provides information on the value of long-term investments.

Published: March 2024

This study was carried out to assess the extent of concentration exposure of As, Cu, Cr, Ni and Mn in the soils of five active dumpsites located at (Eliozu, Oyibo, Eneka, Eleme and Woji) in the city of Port Harcourt Rivers State, Nigeria to evaluate the pollution indices of heavy metals. Soil samples were collected randomly at the quadrant from the dumpsite while control samples were collected from farmland 25 km away from the dumpsite. Some physiochemical parameters (pH, TOC and CEC) of the soils were evaluated using standard techniques, while the heavy metal concentrations were evaluated using Atomic Absorption Spectroscopy (AAS). The pollution levels of soil heavy metals were assessed using several pollution indices. The mean concentration of heavy metals (mg/kg) ranged between As (ND – 0.45), Cr (ND – 2.21), Cu (6.05 – 51.87), Mn (3.24 – 37.91), Ni (ND – 13.50) across the studied dumpsites. The heavy metal levels in soil samples observed were in the order of Cu > Mn > Ni > Cr > As (Eleme), Cu > Mn > As > Ni > Cr (Eliozu), Cu > Mn > Ni > Cr > As (Eneka), Cu > Mn > Cr (Oyigbo), Cu > Mn > Ni > Cr > As (Woji), Cu > Mn > Ni > Cr > As (Control Site). The pH results were relatively acidic across the studied dumpsites ranging from 5.7±0.58 to 6.63± 0.02, while the TOC levels were low to moderate showing no wide disparity in the values. The Cation exchange capacity (CEC) showed a range of 13.98±0.186 (Eneka) to 20.98±0.061 cmol/kg (Woji) across the studied dumpsites. The Igeo values except for Ni, Cu and Mn at Eneka dumpsite, Cr and As in all the studied dumpsites revealed moderate to heavy contamination. Pollution load index (˃ 1) was in the studied dumpsites which implies that there is heavy metal pollution across the studied dumpsites. Anthropogenicity indicates that human activity is mostly responsible for the increase in metals in the studied area. Low ecological risk indices for the heavy metals (Ni, Cu, Cr, Mn, As) were found in all the sampling locations except for copper in Oyibo dumpsite. According to the findings, there is a low to moderate level of heavy metal pollution in the soils from the dumpsite, which can deteriorate the food ecosystem if adequate measures are not put in place.

Published: March 2024

Статья посвящена разработке методики оценки фрактальной размерности облачных образований. Изображения облачного покрова Земли содержат наложенные и частично перекрывающие друг друга различные типы облачности. Каждый тип облачности обладает различными значениями коэффициентов ослабления излучения, поэтому задача разделения типов облачности является важнейшей при вычислении радиационного баланса. Значимый информативный параметр при классификации облачности — фрактальная размерность. Вместе с тем получаемые при использовании ҡсовременныхә методов и алгоритмов оценки фрактальной размерности существенным образом зависят от ҡпозиционированияә объекта. В работе предложена эффективная (по точности), инвариантная относительно ҡпозиционированияә объекта, методика оценки фрактальной размерности.
The research addresses the development of methodology for estimating the fractal dimension of cloud formations. Images of the Earth’s cloud cover contain superimposed and partially overlapped different types of cloud cover. Taking into account that each type of cloudiness has different values of coefficients for radiation attenuation, the problem of separating cloud types is the most important when assessing the radiation balance. The most important feature used in the classiҥcation of cloudiness is the fractal dimension. At the same time, the estimates obtained by using ҡmodernә methods and algorithms for estimating the fractal dimension signiҥcantly depend on the ҡpositioningә of the object. The paper proposes an effective (in terms of accuracy) method for estimating the fractal dimension, which is invariant with respect to the ҡpositioningә of an object.

Process Prediction and Control by an Empirical Model Based on Equivalent Diffusion for Carburizing or Carbonitriding Processes
Authors: Simons R. W. 
Published: March 2024

Abstract
An empirical model has been developed by studying the rate of case formation for various materials. This model uses the relationship observed between material hardenability and case rate. Material hardenability is based on a modified version of Ideal Diameter by using the nominal steel composition with the exception of holding carbon constant at 0.40% (a rough estimation of the carbon level required for effective case depth). It predicts the level of diffusion needed to meet specification requirements and adjust parameters to optimize process design and resulting product characteristics. Inputs needed for process control are the equivalent diffusion number and a material classification. All times, temperatures, carbon set points and level off parameters are automatically downloaded to the equipment for process execution.
Nikrothal PM 58 and Kanthal APMT – Alumina Forming High Temperature Steels Offering New Opportunities in Heat Treatment
Authors: Chandrasekaran Dilip , Helander Thomas , Nockert Olovsjö Johanna 
Published: March 2024

Abstract
In this paper a novel nickel-base, alumina forming alloy, Nikrothal PM 58 is introduced. Similar to the previously developed, ferritic, iron-base alloy Kanthal APMT, the alloy bases its corrosion resistance on the formation of an adherent surface alumina layer. They both have high creep strength, due to a dispersion strengthened microstructure from the powder metallurgical processing route. This unique combination of properties enables application temperatures ranging from 1472 F (800°C) to 2372 F (1300°C) and new possibilities to design high temperature components like mesh belts, furnace rollers and muffles. Mechanical and corrosion properties for Nikrothal PM 58 at 2012 F (1100°C) and 2192 F (1200°C) are presented and compared with other commercial high temperature alloys.

Published: March 2024

Abstract
In single-shot hardening applications, heat treated components often feature a variety of geometric complexities including variable wall thicknesses, sharp diameter transitions, lightening holes, slots, etc. Due to the inherent 3D electromagnetic nature of single-shot coils and the complex geometry components which they must accommodate, the design and optimization of single-shot hardening coils is typically a demanding and intricate task. This paper presents combined electromagnetic-thermal and thermal-mechanical FEA simulation results for the single-shot induction hardening of a power transmission shaft. The simulation results, including electromagnetic, thermal, metallurgical, and mechanical data demonstrate the value of computer simulation in the design and development of single-shot induction hardening systems.

Test Piece Representation of Carburized Gear Heat Treatment
Authors: Pershing Michael A. , Maniruzzaman Mohammed 
Published: March 2024

Abstract
Test pieces are often used for hardened depth and microstructure checks on carburize and harden heat treatment processes so that actual parts are not destroyed for the sake of quality assurance. For gear heat treatment, this is especially important because of costly prior processing. This paper reports on a study to determine the proper size and material of a cylindrical test piece that could be used as an appropriate indicator of the hardened depth and microstructure of the actual gear. Heat treat simulation is used to examine cooling rates for various diameters of test pieces to see how they compare to different modules of tooth sizes on gears. The surface cooling rates up to depths of 1.5 mm are examined to size the test piece correctly.
Developing Rotary-Arm Type Test System with a Small Platinum Ball Probe for Determination of Cooling Characteristics of Quenchants
Authors: Arimoto Kyozo , Shimaoka Mitsuyoshi , Ikuta Fumiaki 
Published: March 2024

Abstract
Performances of quenchants have been enhanced and maintained based on their cooling characteristics determined by specific test systems. A rotary-arm type test system with a small ball probe has been developed for this purpose by making prototypes. Its unique concept derived mainly from a circular motion of a small ball probe in quenchants was proposed by Tawara in 1941. The prototypes have been realized by current heating, measuring and mechatronics techniques. Finally the probe material has been changed from nickel alloy to platinum for resolving the discoloration and thermal aging problems on the probe surface. The performance of the prototypes has been verified by systematic tests using specific quenchants under various cooling conditions.
An Inverse Method for Determining Steel Properties for Simulation of Phase Transformations During Quenching
Authors: Biba N.V. , Shitikov A.A. , Alimov A.I. 
Published: March 2024

Abstract
Accurate simulation of phase transformation during quenching of steels requires comprehensive knowledge of thermal and physical properties of the material. In cases when reliable material data are not available they can be obtained by a two-stage inverse method proposed in the paper. It includes a Jominy test of a specimen with thermocouples. At the first stage, we obtain TTT diagrams by means of analyzing cooling curves for several regions of the specimen obtained from experimental results. The second stage includes correction of material thermo-physical properties, i.e. the thermal conductivity and specific heat for each phase as well as estimation of the latent heat for each phase transformation. Parameters fitting is carried out iteratively by comparing FEM simulation and experimental results. Varying of parameters is performed with evolutionary methods of multi-parameter optimization. The developed method is implemented in QForm commercial software.
