DEM analysis of crushing evolution in cemented granular materials during pile penetration
Publication Name: Computers and Geotechnics
Publication Date: 2023-09-01
Volume: 161
Issue: Unknown
Page Range: Unknown
Description:
The present study demonstrates that the 3D discrete-element method provides a practical model approach to visualize the cemented grain crushing evolution under pile penetration. A combined method using a rigorous breakage criterion based on octahedral shear stress (OSS) was implemented in the particle flow code PFC3D. First, the pile penetration is simulated by considering the grains as uncrushable with a screening of highly stressed grains exceeding the threshold defined by the OSS failure condition. Then, the simulation is repeated where crushable agglomerates replace the highly stressed grains. This method is more accurate than the replacement method and more efficient than the agglomerate method. A quarter of the numerical model was considered after validation to achieve an acceptable computational time for parametric studies. Parametric investigations were performed on the effects of particle crushing, boundary conditions, pile tip shape, and pile penetration velocity on the penetration resistance behavior. In agreement with the observations of the physical calibration chamber, the present results indicate that the proposed modeling approach is reliable in reproducing the concentration of crushed granular material particles in the vicinity of the pile tip and shaft. In addition, grain crushing has been found to reduce both penetration and shaft resistance.

Eco-friendly strategic goals and the performance of innovative green processes: The impact of green intellectual capital
Publication Name: International Journal of Innovative Research and Scientific Studies
Publication Date: 2025-01-01
Volume: 8
Issue: 1
Page Range: 191-201
Description:
The purpose of this study is to check the intellectual capital's role in shaping green process innovation. This article contends the company's capacity to create, possess, incorporate, and implement environmentally friendly intellectual assets in its activities will result in a higher degree of performance in terms of innovative green processes. This performance serves as an indicator of the company's enduring dedication to an environmentally conscious strategy. The industries chosen for this study comprised textile, chemical, pharmaceutical, and steel based in Mexico. The random sampling technique was used to gather data. Upon analyzing the gathered data, we used only 253 questionnaires for analysis, representing a response rate of 42.7%. Findings indicate green strategic intent significantly influences three components of intellectual capital: human, relational, and organizational capital. Three components of intellectual capital significantly influence green process innovation. A green strategy can be successfully implemented by the implementation of intangible resources. Mere tangible resources are insufficient to gain superior green innovation performance; the interaction of these two resources (tangible and intangible) is complementary. Companies are adopting environmental strategies to mitigate the environment's harmful impact and meet stakeholders' demands. The study’s practical implications aim to improve companies’ environmental performance, specifically their green performance, through the implementation of green innovation.

Using the CERES-Maize Model to Simulate Crop Yield in a Long-Term Field Experiment in Hungary
Publication Name: Agronomy
Publication Date: 2022-04-01
Volume: 12
Issue: 4
Page Range: Unknown
Description:
Precision crop production requires accurate yield prediction and nitrogen management. Crop simulation models may assist in exploring alternative management systems for optimizing water, nutrient and microelements use efficiencies, increasing maize yields. Our objectives were: (i) to access the ability of the CERES-Maize model for predicting yields in long-term experiments in Hungary; (ii) to use the model to assess the effects of different nutrient management (different nitrogen rates—0, 30, 60, 90, 120, and 150 kg ha−1). A long-term experiment conducted in Látókép (Hungary) with various N-fertilizer applications allowed us to predict maize yields under different conditions. The aim of the research is to explore and quantify the effects of ecological, biological, and agronomic factors affecting plant production, as well as to conduct basic science studies on stress factors on plant populations, which are made possible by the 30-year database of long-term experiments and the high level of instrumentation. The model was calibrated with data from a long-term experiment field trial. The purpose of this evaluation was to investigate how the CERES-Maize model simulated the effects of different N treatments in long-term field experiments. Sushi hybrid’s yields increased with elevated N concentrations. The observed yield ranged from 5016 to 14,920 kg ha−1 during the 2016–2020 growing season. The range of simulated data of maize yield was between 6671 and 13,136 kg ha−1. The highest yield was obtained at the 150 kg ha−1 dose in each year studied. In several cases, the DSSAT-CERES Maize model accurately predicted yields, but it was sensitive to seasonal effects and estimated yields inaccurately. Based on the obtained results, the variance analysis significantly affected the year (2016–2020) and nitrogen doses. N fertilizer made a significant difference on yield, but the combination of both predicted and actual yield data did not show any significance.

Cataloguing microalgae and Cyanobacteria strains from the Mosonmagyaróvár Algal Culture Collection with in vitro antagonistic activity against phytopathogenic fungi and oomycetes
Publication Name: Phytoparasitica
Publication Date: 2023-09-01
Volume: 51
Issue: 4
Page Range: 747-762
Description:
Microalgae produce many secondary metabolites that are biologically active, including compounds that inhibit microbial growth. These could potentially function as biofungicides. The first selection criteria for potential strains suitable in the phytosanitary market is good in vitro inhibition of growth against specific phytopathogenic fungi and oomycetes and higher biomass productivity rates. In the present study, water extracts were prepared from 280 strains comprising of 33 Cyanophyceae strains (13 genera), 157 Chlorophyceae strains (29 genera), 80 Trebouxiophyceae strains (19 genera), 5 Klebsormidiophyceae strains (1 genus) and 1 Zygnematophyceae strain. These were tested in vitro against 6 phytopathogenic fungi and 3 phytopathogenic oomycetes. In total, 45% of the species had mycelial growth inhibitory activity against at least one pathogen. Cyanobacteria had the highest “hit-rate” (64%), followed by the Chlorophyceae (49%) and Trebouxiophyceae (30%). Water extracts of 19 strains had fungicidal and/or oomyceticidal activity – these were predominantly Cyanobacteria. The Cyanobacteria displayed a wider spectrum of inhibition with five strains being active against three or more phytopathogenic strains. Trichormis variabilis MACC-304 and Tolypothrix tenuis MACC-205 had inhibitory activity against 6 phytopathogens and Nostoc linckia MACC-612 inhibited 4 phytopathogenic strains. Each Chlorophyta strain was only active against 1-2 strains. However, the daily productivity rates of Cyanobacteria were significantly lower than Chlorophyta strains. Further investigation of 15 Nostocales species (Nostocaceae, Tolypothrichaceae and Calotrichaceae) showed the Nostoc species generally had significantly lower biomass generation compared to other Nostocacaeae strains. The most promising strain was Tolypothrix tenuis MACC-205 which had the most potent, broad spectrum fungal and oomyceticidal inhibitory activity as well as significantly higher daily biomass productivity rates. Thus, Cyanobacteria can potentially be developed as an effective agricultural tool for environmentally-friendly disease management.

CONVERGENCE STRATEGIES FOR OPTIMIZING ANTENNA SELECTION IN A COMMUNICATION SYSTEM: A COMPLEX LINEAR DIOPHANTINE FUZZY SOFT SET APPROACH
Publication Name: Applied Engineering Letters
Publication Date: 2024-09-01
Volume: 9
Issue: 3
Page Range: 146-161
Description:
The need to grow in a secure and tranquil environment demands the efforts of an armed force, and only with a strong-armed force can a country ensure its national security. In military activities, communication devices are widely used to confuse enemies' radars or communications to abandon their strategies and execute planned actions. The range of communication devices depends mainly on the antennas used. Army sustainability goals are to upgrade the effectiveness of the mission, reduce army environmental impact, build green sustainable structures, and attain the energy level independence that improves the continuity of operations which are indispensable to the mission. The primary goal of this paper is to present an innovative mathematical model for selecting pertinent antennae in communication devices using an innovative idea called a Complex Linear Diophantine Fuzzy Soft set based on the various attributes by incorporating decision-making techniques. Also, some of its beneficial operations such as Complement, AND, OR, Extended Union, and Extended Intersection, are presented in concert with the properties and theorems to apprise the viability of the proposed paper. This concept is more applicable and necessary to assess real-life situations using mathematical modeling.

Sustainability in Public Finances Concerning Transfer Pricing in the EU
Publication Name: Chemical Engineering Transactions
Publication Date: 2023-01-01
Volume: 107
Issue: Unknown
Page Range: 523-528
Description:
Ensuring the sustainability of public finances is a crucial concern for the European Union, particularly in the context of transfer pricing, which is focused on tax base erosion and profit shifting. Transfer pricing, involving the internal transfer of goods, services, or intellectual property between related entities, can significantly impact member states' tax revenues and overall economic stability. Base erosion and profit shifting is a term used to describe tax planning strategies that multinational companies use to exploit gaps and mismatches in tax rules to artificially shift profits to low or no-tax jurisdictions, thereby reducing their overall tax liability. The scope of this study examines these two topics, mainly by using jurisprudential methods and analysis of scientific sources, as well as to research the effect of tax-based erosion and inequality among state jurisdictions. The assessment and analysis of the problems in these areas have been going on for years, and in essence, the neuralgic points are clear in terms of problem definition. Nevertheless, appropriate normative solutions have either not been developed to a full extent or are being implemented slowly. Considering the lengthy process of adopting normative rules, the main aim of this study is to make suggestions for the field of law enforcement and organs of public administration that could lead to changes in the areas of transfer-pricing, base erosion, and profit shifting. In conclusion, three key areas of action are proposed. Firstly, the promotion and everyday implementation of digital taxation contribute to the efficient exchange of data. Secondly, much closer cooperation between tax authorities on this basis can be strengthened at the Member State level in practical administration. Thirdly, the more effective safeguarding of the single market by national administrations.

Ecotoxicological investigations of milking cow slurry and changes of oestrogenic compounds in the solid and liquid phase
Publication Name: Energy Ecology and Environment
Publication Date: 2022-04-01
Volume: 7
Issue: 2
Page Range: 97-110
Description:
Due to the appearance of intensive livestock-rearing systems since the 1970s, a vast amount of liquid manure (slurry) has been produced. The application and utilization are partly regulated for this special substance, which contains urine, excrement, process water, and other chemicals, such as insecticides and disinfectants. Our research was conducted on a slurry management system of a dairy cattle farm, focusing on the investigation of the presence of oestrogenic substances and toxicity of slurry before and after using a separator technology. Yeast oestrogen screen shows in this study that the separation of the liquid and solid phases of slurry contributes to the reduction in oestrogenic substances. Based on the toxicological studies, the growth inhibition of algae was 93%, and the inhibition of the germination of higher plant seeds was 25%, without separation. After separation of the phases, growth and germination were comparable with the negative control; moreover, some stimulation was detected. Consequently, harmful substances were removed with the suspended solid phase. From the present study, we can conclude that stakeholders should support separation technology in intensive livestock-rearing systems, and ecotoxicological investigations obviously help the risk management of slurry utilization. To our best knowledge, this is the first paper presenting detailed and complex toxicological study on slurry samples.

Two new species from the genus Phymatodiscus Berlese, 1917 from Brunei (Acari: Mesostigmata: Phymatodiscidae)
Publication Name: Acarologia
Publication Date: 2026-01-01
Volume: 66
Issue: 2
Page Range: 511-520
Description:
Two new species were collected from the family Phymatodiscidae Kontschán and Ermilov, 2023 during the study of the soil-dwelling Uropodina from Brunei Darussalam. Phymatodiscus bruneiensis n. sp. has very unusual characters (such as marginal prolongations situated only on the caudal area) that are visible only in the Japanese P. iriomotensis Hiramatsu, 1979, but the shape and positions of the dorsal, ventral and sternal setae differ between those two species. The second species, P. hiramatsui n. sp., lacks marginal prolongations; this character state is observable only in P. polyglottis Hirschmann, 1977 (New Guinea), but the known species differ from it in the shape of the elevated parts of the dorsal shield, the sculptural pattern and the dorsal setation.
