Annak ellenére, hogy a vállalkozók gyakran környezetvédelmi, politikai és társadalmi célok teljesítését tűzik ki maguk elé, a vállalkozói énhatékonyságon kívüli, más feladatspecifikus énhatékonyság szerepét a vállalkozói szándékban, valamint az énhatékonyságok társadalmi identitással való kapcsolatát nagyrészt figyelmen kívül hagyta eddig a vállalkozói szakirodalom. Mivel a vállalkozói sikerhez erős interperszonális készségek is szükségesek, illetve egyes vállalkozók domináns célja a társadalmi értékteremtés, ebben a tanulmányban azt vizsgáljuk, hogy a szociális énhatékonyság milyen szociális identitás esetén és miért lehet a vállalkozói szándék mögött húzódó fontos tényező. Eredményeink azt mutatják, hogy míg a darwini társadalmi identitás vállalkozói szándékra gyakorolt hatását csak a vállalkozói énhatékonyság, addig a közösségi társadalmi identitás hatását a szociális és a vállalkozói énhatékonyság is teljes mértékben közvetíti. A missziós társadalmi identitású egyének azonban arra számítanak, hogy egyéb feladatspecifikus énhatékonyságra is szükségük lesz ahhoz, hogy sikeres vállalkozóvá váljanak. Eredményeink szerint tehát a vállalkozói szerepeket követve a vállalkozói énhatékonyság mellett más feladatspecifikus énhatékonyságokat is célszerű lenne figyelembe venni a vállalkozói szándék előzményeinek vizsgálatakor. Az észlelt környezeti támogatás nem moderálta a vizsgált énhatékonyságok közvetítő hatását.

Authors: Lányi Beatrix , Fűrész Diána Ivett
Published: July 2024

A technológia a sport területén napjainkra a teljesítmény, illetve a versenyképesség növelésének egyik legfontosabb tényezőjévé vált, hiszen a technológiai innovációk jelentős mértékben hozzájárulnak a sportágak fejlődéséhez és a sportolók teljesítményének javításához. Ahhoz, hogy a sportolók folyamatosan túlszárnyalhassák az emberi teljesítmény határait, különösen innovatív eszközökre és módszerekre van szükség. Kutatásunk célja a technológiai innováció sportteljesítményre gyakorolt hatásának mérése, aminek érdekében egy, az úszásban az egyik legjelentősebb áttörést okozó innováció, a cápadressz világcsúcsokra gyakorolt hatását vizsgáltuk. Empirikus kutatásunk során 14 versenyszám esetében elsőként Catmull–Rom-spline-interpolációt alkalmaztunk, majd a „kvázi” ekvidisztáns idősorokon strukturálistörés-teszteket végeztünk. Eredményeink egyértelműen kimutatták, hogy a cápadressz alkalmazása 7 versenyszámban ténylegesen olyan világcsúcsidőket hozott, amelyek áttörést jelentettek, vagyis az innováció bevezetése szignifikánsan javította a sportolók egyéni teljesítményét
La experiencia española de la banca emisora: la pluralidad de emisión en el siglo XIX
Authors: Blasco-Martel Yolanda , Sudrià i Triay Carles
Published: July 2024

En las décadas centrales del siglo XIX, España desarrollo un sistema bancario basado en la pluralidad de emisión. Diversos bancos fueron autorizados por el Estado para hacer circular sus billetes en sus respectivas provincias. Este proceso dio lugar a un mosaico de bancos emisores. Su existencia facilito la aceptación del billete bancario, a la vez que tales bancos suministraron medios de pago en aquellos territorios en los que actuaron. Los efectos fueron importantes tanto para la extensión del billete como para la economía. En este trabajo se sintetiza la experiencia emisora española que se vio afectada por la crisis de 1866 y termino en 1874 con el monopolio emisor en manos del Banco de España.

Design and Optimization of One Special Microperforated Plate-Labyrinth Coupled Structure (MPPS-LS): From the View of Numerical Simulation
Authors: Zhu Zhiyuan , Ma Lifeng , Li Chunxiao , Xie Xiaolong , Hu Jiajia
Published: July 2024

Controlling large-wavelength acoustic waves via small-size structures is an important direction for the field of noise control. Since porous acoustic material can only absorb low-frequency sound waves when their thickness is approximately one-fourth of the wavelength, such acoustic material is not effective when controlling the large-wavelength acoustic waves with small-size structures. Therefore, the resonant acoustic material has been usually chosen to absorb low-frequency sound waves instead. As a typical resonant acoustic material, microperforated plate structures (MPPS), need one large cavity with low space utilization to absorb the low-frequency acoustic waves. The microperforated plate-labyrinth coupled structure (MPPS-LS) has been proposed with the goal of improving low-frequency sound absorption ability, which is consisted of a MPPS and three separated second-order LS coupled together. The mathematical model has been established using the acousto-electric analogy method and transfer matrix method to examine the impact of the structural parameters of each part on the acoustic characteristics. According to this study, the coupled structure is compact in size and has a good low and medium-frequency acoustic absorption effect, combining low and medium-frequency acoustic absorption characteristics of both the MPPS and LS. The sound absorption of the structure after optimized design is testing using impedance tube.
A Smooth Gradation Based FE Model for Dynamic Analysis of Functionally Graded Plates and Folded Plates in Hygrothermal Environments
Authors: Singh Ashish Kumar , Sahu Atanu
Published: July 2024

Functionally graded (FG) plates and folded plates are now integral components in aerospace, aviation, nuclear, and marine structures. Modelling FG structures with diverse material properties presents notable challenges, often necessitating the use of custom coding and analytical methods which may not always be suitable for commercial projects due to their time-consuming nature. It is from this perspective that a novel computational model based on the finite element (FE) approach is developed in the present research for free vibration analysis of FG plates and folded plates under hygrothermal conditions. A smooth gradation based material modelling is implemented in the FE model for FG structures using an analytical function, adhering to the power law, within the COMSOL Multiphysics software. The first order shear deformation theory is implemented to model the FG plate. Both the linear and uniform rise of temperature through the plate's thickness are considered whereas the moisture concentration is assumed to rise uniformly. The prestressed eigenfrequency analysis is adopted so that the residual stresses resulting from non-linear strains generated due to hygrothermal effect can be incorporated. The results of the present FE model are validated with other analytical methods and the layerwise theory based approach from published literature. Thorough numerical simulations involving variations in temperature, moisture, power law indices, crank angle, boundary conditions and thicknesses are conducted to explore the vibrational behavior of the FG panels in hygrothermal conditions. The presented computational model offers an efficient and straightforward approach for the dynamic analysis of FG panels having complex geometries and boundary conditions in extreme environments.
Low-Frequency Flexural Wave Acoustic Insulation Characteristics of a Double-Layer Metamaterial Plate

Published: July 2024

The effects of geometric parameters and constituent material parameters on the flexural wave bandgap of a locally resonant double-layer metamaterial plate are investigated using the finite element method. Reasonable parameters are obtained through optimization; then, a double-layer plate made of ABS material with added aluminum mass blocks is designed. The results show that it can open the low-frequency (112--124 Hz) flexural wave bandgap at a subwavelength size. The metamaterial plate is modeled as an equivalent spring-mass system, and the frequency range with negative density for the equivalent dynamic mass is consistent with the width of the flexural wave bandgap. The bandgap generation mechanism is further elucidated. Sound insulation performance of double-layer metamaterial panels verified in an acoustic chamber. The maximum amplitude of STL is achieved at the 112 Hz point in the bandgap frequency range, which indicates that the low-frequency bandgap can effectively reduce vibration and noise. These results demonstrate that this novel double-layer metamaterial plate has wide applications in engineering.

O presente estudo objetivou analisar os principais desafios e possibilidades advindos dos processos formativos relacionados aos estágios curriculares supervisionados à luz de entrevistas conduzidas por meio da trajetória de vida com professores de Educação Física escolar participantes de um processo de formação e desenvolvimento profissional docente. Participaram desse processo seis docentes vinculados ao ensino público do Estado de São Paulo, sendo quatro mulheres e dois homens. Após transcritas, as entrevistas foram submetidas à análise de conteúdo, resultando em duas categorias: “Desafios acerca dos processos de estágio: falta de compreensão, práticas pouco assertivas e pouca relação entre universidade e escola”; e “Possibilidades de desenvolvimento da formação: estágio curricular como campo de conhecimento e desenvolvimento de experiências e práticas significativas”. Com base nos achados analisados no estudo, é possível concluir que os professores relataram tanto experiências de pouca assertividade e algumas dificuldades nesse itinerário, quanto elencaram possibilidades de valorização do estágio como processo formativo. Tais postulados, à luz dos dados e da literatura, permitem inferir que o estágio é um campo de conhecimento crucial da formação, gerando tensões e impactos significativos nas crenças e representações sobre o que é ser um profissional, pois se forma para uma profissão.

Published: July 2024

Objective: Mitochondrial fatty acid oxidation is a metabolic pathway whose dysregulation is recognized as a critical factor in various cancers, because it sustains cancer cell survival, proliferation, and metastasis. The acyl-CoA synthetase long-chain (ACSL) family is known to activate long-chain fatty acids, yet the specific role of ACSL3 in breast cancer has not been determined. Methods: We assessed the prognostic value of ACSL3 in breast cancer by using data from tumor samples. Gain-of-function and loss-of-function assays were also conducted to determine the roles and downstream regulatory mechanisms of ACSL3 in vitro and in vivo. Results: ACSL3 expression was notably downregulated in breast cancer tissues compared with normal tissues, and this phenotype correlated with improved survival outcomes. Functional experiments revealed that ACSL3 knockdown in breast cancer cells promoted cell proliferation, migration, and epithelial–mesenchymal transition. Mechanistically, ACSL3 was found to inhibit β-oxidation and the formation of associated byproducts, thereby suppressing malignant behavior in breast cancer. Importantly, ACSL3 was found to interact with YES proto-oncogene 1, a member of the Src family of tyrosine kinases, and to suppress its activation through phosphorylation at Tyr419. The decrease in activated YES1 consequently inhibited YAP1 nuclear colocalization and transcriptional complex formation, and the expression of its downstream genes in breast cancer cell nuclei. Conclusions: ACSL3 suppresses breast cancer progression by impeding lipid metabolism reprogramming, and inhibiting malignant behaviors through phospho-YES1 mediated inhibition of YAP1 and its downstream pathways. These findings suggest that ACSL3 may serve as a potential biomarker and target for comprehensive therapeutic strategies for breast cancer.

How can the Government Promote Sustainable Cooperation between Schools and Enterprises? A Quadrilateral Evolutionary Game Study
Authors: Wang Hexin , Liu Chao , Dai Yu
Published: July 2024

Facilitating sustainable cooperation between schools and enterprises has become an important concern in many countries. However, there remains a gap in understanding the approaches taken by central and local governments to foster such cooperation through the lens of evolutionary game theory. Therefore, this paper aims to develop a quadrilateral evolutionary game model involving schools, enterprises, the central government, and local governments, to analyze the conditions under which governments can effectively promote school-enterprise cooperation. Our findings indicate that benefit is a decisive factor that affects the strategies of all parties. When the benefits of cooperation are sufficiently attractive, schools and enterprises are inclined to cooperate with each other independently of governmental intervention. While increasing incentives and penalties from the central government and local governments can stimulate school-enterprise cooperation, these measures are not sustainable in the long term. Additionally, the impact of the central government’s incentives and penalties on local governments in promoting school-enterprise cooperation is limited. Enhancing policy efficacy and the practical outcomes of school-enterprise cooperation is essential, which not only strengthens the bond between schools and enterprises but also ensures deep and enduring governmental involvement.

Published: July 2024

Earthquake forecasting is arguably one of the most challenging tasks in Earth sciences owing to the high complexity of the earthquake process. Over the past 40 years, there has been a plethora of work on finding credible, consistent and accurate earthquake precursors. This paper is a cumulative survey on earthquake precursor research, arranged into two broad categories: electromagnetic precursors and radon precursors. In the first category, methods related to measuring electromagnetic radiation in a wide frequency range, i.e. from a few hz to several MHz, are presented. Precursors based on optical and radar imaging acquired by space borne sensors are also considered, in the broad sense, as electromagnetic. In the second category, concentration measurements of radon gas found in soil and air, or even in ground water after being dissolved, form the basis of radon activity precursors. Well-established mathematical techniques for analysing data derived from electromagnetic radiation and radon concentration measurements are also described with an emphasis on fractal methods. Finally, physical models of earthquake generation and propagation aiming at interpreting the foundation of the aforementioned seismic precursors, are investigated
Pan-Genome Analysis of TRM Gene Family and Their Expression Pattern under Abiotic and Biotic Stresses in Cucumber
Authors: Zhao Li li , Wang Ke , Wang Zi mo , Chu Shun peng , Chen Chun hua , Wang Li na , Ren Zhong hai
Published: July 2024

Cucumber (Cucumis sativus L.) is a vital economic vegetable crop, and TRM (TONNEAU1 Recruiting Motif) gene plays a key role in cucumber organ growth. However, the pan-genomic characteristics of the TRM gene family and their expression patterns under different stresses have not been reported in cucumber. In this study, we identified 29 CsTRMs from the pan-genomes of 13 cucumber accessions, with CsTRM29 existing only in PI183967. Most CsTRM proteins exhibited differences in sequence length, except five CsTRMs having consistent protein sequence lengths among the 13 accessions. All CsTRM proteins showed amino acid variations. Analysis of CsTRM gene expression patterns revealed that six CsTRM genes strongly changed in short-fruited lines compared with long-fruited lines. And four CsTRM genes strongly responded to salt and heat stress, while CsTRM14 showed responses to salt stress, powdery mildew, gray mold and downy mildew. Some CsTRM genes were induced or suppressed at different treatment timepoint, suggesting that cucumber TRM genes may play different roles in responses to different stresses, with expression patterns varying with stress changes. Remarkably, the expression of CsTRM21 showed considerable change between long and short fruit and in responses to abiotic stresses (salt stress, heat stress) as well as biotic stresses (powdery mildew, gray mold), suggesting a dual role of CsTRM21 in both fruit shape determination and stress resistance. Collectively, this study provided a base for further functional identification of CsTRM genes in cucumber plant growth and stress resistance.

Plant biomass could become a new world-class "currency" because almost everything can be made of it: fuels, foods, feeds, constructing materials, furniture, etc. Currently, growing biomass for energy needs is particularly relevant in so complicated socioeconomical situation. There are important its productivity and the lowest possible ecological footprint. Can increasing crop biodiversity address these challenges? A field experiment was started at the Vytautas Magnus University Agricultural Academy in 2020-2022. Maize, hemp and faba bean were grown as single, binary and ternary crops to determine its effect on soil properties. Studies have shown that most intercrops failed to stabilize soil aggregate composition, NPK levels and pH, and enzyme urease activity. Binary maize-hemp and the ternary crops reduced the amount of the main macroelements in the soil the most because of the highest yields, which were removed from the fields. Regardless of the ecological services provided by faba beans, biomass removal leads to degradation of most soil properties and making the soil vulnerable to erosion. In the future, the cultivation of such multicrops should be investigated under conditions of more abundant fertilization or the effect of green manure should be used by increasing the number of fast- and short-growing interior plant species in the cultivation.
A New MATLAB-Based Simulation Interface for Serial Robots
Authors: Szanto Anna-Vanessza , Brișan Cornel
Published: July 2024

The development of virtual models has recently been generalized in the field of complex mechatronic product design. Virtual models have various advantages such as: the systemic design approach, most often parametric, the implementation of extreme, expensive, and perhaps risky scenarios for the operation of the designed product, the testing of a large number of variants, etc.
The main contribution of the paper consists of the development of an interface family called DeSeRoI (Dedicated Serial Robot Interface). Each member of the interface family integrates Simulink libraries and is created by the programmer in accordance with user requests. It follows that the interfaces composing the DeSeRoI family can have different levels of complexity depending on user needs and constraints.
We are implementing a MATLAB-based application with user-provided configuration for serial robots in order to automatically visualize the kinematics data and simulation. Within MATLAB, two scripts are created responsible for generating Simulink models that compute the kinematics problem. One of the scripts (Main) saves information about the configuration of the robot and the other one (Generates_Simulink_Models) computes the kinematics problem. Different types of functions (software module) have been developed. Using these functions, the Simulink models result as modular entities. The automated approach eases user’s interaction and understanding of serial robots’ kinematics by performing the simulation procedure in a shorter amount of time and with higher efficiency, assuring a precise outcome despite the chosen parameters.
Information-Theoretic Modeling of Categorical Spatiotemporal GIS Data
Authors: Percy David , Zwick Martin
Published: July 2024

An information-theoretic data mining method is employed to analyze categorical spatiotemporal Geographic Information System land use data. Reconstructability Analysis (RA) is a maximum-entropy-based data modeling methodology that works exclusively with discrete data such as those in the National Land Cover Database (NLCD). The NLCD are organized into a spatial (raster) grid, and are available in consistent format for every five years from 2001 to 2021. An NLCD tool reports how much change occurred for each category of land use; for the study area examined the most dynamic class is Evergreen Forest (EFO), so the presence or absence of EFO in 2021 was chosen as the dependent variable that our data modeling attempts to predict. RA predicts the outcome with approximately 80% accuracy using a sparse set of cells from a spacetime data cube consisting of neighboring lagged-time cells. When the predicting cells are all Shrubs & Grasses there is a high probability for a 2021 state of EFO, while when the predicting cells are all EFO, there is a high probability that the 2021 state will be not-EFO. These findings are interpreted as detecting forest clear-cut cycles that show up in the data, and explain why this class is so dynamic. This study introduces a new approach to analyzing GIS categorical data and expands the range of applications that this entropy-based methodology can successfully model.
Impact of Residual Strains on the Carrier Mobility and Sability of Perovskite Films
Authors: Slimani Moulay Ahmed , Gerlein Luis Felipe , Izquierdo Ricardo , Cloutier Sylvain G
Published: July 2024

Solution-based inorganic-organic halide perovskites are of great interest to researchers because of their unique optoelectronic properties and easy processing. However, polycrystalline perovskite films often show inhomogeneity due to residual strain induced during the film’s post-processing phase. In turn, these strains can impact both their stability and performances. An exhaustive study of residual strains can provide a better understanding and control of how they affect the performance and stability of perovskite films. In this work, we explore this complex interrelationship between residual strains and electrical properties for methylammonium \chemform{CH_3NH_3PbI_{3-x}Cl_x} films using grazing incident X-ray diffraction (GIXRD). We correlate with their resistiviy and carrier mobility using Hall effect. The sin^2($\psi$) technique is used to optimize the annealing parameters for the perovskite films. We also establish that temperature-induced relaxation can yield significant enhancement of the charge carrier transports in perovskite films. Finally, we also use Raman micro-spectroscopy to assess the degradation of perovskite films as a function of their residual strains.

Researches on the runoff and sediment reduction effects of soil and water conservation measures are being on the rise, which is of great significance for carrying out strategic on soil and water conservation in the Yellow River Basin. Through the analysis of various soil and water conserva-tion measures, runoff, sediment, and rainfall datas in the Sanchuan River Basin from 1960 to 2019, we use the lagrange multiplier method to determining the threshold year of soil and water con-servation measures on runoff and sediment processes. The preliminary conclusion is as follows: The trend of flood season rainfall and annual rainfall in the Sanchuan River Basin is consistent. The 10-year average rainfall in each periods indicates that before 2000, it gradually decreased and then significantly increased. The 10-year average runoff showed a gradual decrease before 2010, followed by a sudden increase, while the 10-year average sediment has shown a decreasing trend years by years, especially after the centralized treatment period. Terrace and dam measures show a trend of first decreasing, then increasing, and then approaching stability during different treat-ment periods, while the trend of forest and grass measures is slightly decreasing and then in-creasing rapidly. The runoff and sediment reduction effects of various soil and water conservation measures during different treatment periods indicate that the runoff reduction effect reached its peak in 2005, while the sediment reduction benefit reached its best in 2015. Based on the compre-hensive benefits of runoff and sediment regulation, 2015 are considered as the threshold year for various soil and water conservation measures, with each measure areas being 4.86 × 104, 17.91 × 104, 1.20 × 104, and 0.83 × 104hm2, respectively. The research results will have certain reference significance for the high-quality development of soil and water conservation in the Yellow River Basin.

Great Himalayan range with regions namely, Jammu & Kashmir, Ladakh and high altitude parts of north eastern states inherently experience high solar exposure, cold, arid climate and significantly challenging geography. With a scarcity of affordable public housing projects in these regions a grid enabled low energy residential prototype is proposed having the capability to operate on nearly zero consumption of heating and cooling energy with the application of indigenous and contemporary energy efficient passive design techniques. Preliminary study, development of design and reading of simulation results were applied for the performance and benefit analysis of the low energy building prototype. Analysis of the climatic zone further classified and narrowed the design criterion by confirming upon beneficial architectural components proven to be energy efficient. These architectural components include, optimization of direct solar gain and orientation of building envelope, modified trombe wall system, traditional sunrooms, solar chimney with openable vents, efficient spatial planning and compliance of relevant parameters such as window-wall-ratio (WWR). The proposed low energy housing for the economically weaker section is estimated to save nearly 50% of active fuel based household heating energy. Site has been planned in such a way that about 100% of required electricity can be generated from on site renewable energy for the proposed infrastructure, it is proven more beneficial if additional electricity is generated to offset the power supply and result in lower or subsidized electricity bills. Design is compliant to different codes relevant to energy conservation and low-income housing with an embodied carbon of about 1.2 kgCO2/m2 per dwelling unit giving ‘A’ grade in cradle to gate impacts. The findings and performance of this prototype can serve as a guideline for energy efficient design in low income group housing situated in severe cold and arid regions of India such as Ladakh (U.T.).

Prostate cancer (PCa) ranks as the second most fatal and sixth most prevalent cancer among males globally. This study focuses on leveraging deep learning networks to detect the Gleason grading of prostate cancer from histopathology images stained with Hematoxylin and Eosin (H&E). Six pathologists annotated the images, resulting in six distinct labels for each input image. A common ground truth label was established through majority voting approach. Subsequently, the dataset was trained using architectures: UNeT, UNeT++, DeepLabV3, DeepLabV3+, and GAN based segmentation network. Notably, GAN based network demonstrated superior performance, achieving an F1-score of 0.872 and a Jaccard Index of 0.777, outperforming the other architectures considered in this study.

Source water quality is a key determinant of drinking water quality. The recast European Union 2020/2184 drinking water directive (DWD) introduced the obligation for comprehensive risk assessment in drinking water supplies, including the water source and incorporated new elements of natural origin in the list of parameters to be monitored. The current study is the first comprehensive assessment of 15 natural elements (B, Ba, Be, Ca, Co, K, Li, Mg, Mo, Na, Se, Sr, Ti, U and V) in 1155 (82%) Hungarian drinking water sources, including surface water, bank filtered and groundwater sources. Parameters posing a risk to health (Se, V and U) were typically below the lower limit of quantification (LOQ), but higher concentrations (max. 7.0, 17 and 41 µg/L, respectively) may occur in confined locations, the latter exceeding the DWD parametric value in one water supply. Li in a small geographical area, Mg and Ca in the majority of the water supplies reached the concentration range assumed to be protective to health. Water sources were grouped in 6 clusters based on their element distribution, some of them also showing clear geographical patterns. Water types were not differentiated, with the exception of karstic waters (dominated by Ca and Mg). None of the investigated parameters are expected to be a source of public health concern.

Colombia has initiated the process of participating in the environmental projects of the United Nations global agenda for the mitigation of climate change and the protection of biodiversity. Consequently, organizations within the solidarity sector have devised projects with the objective of aligning themselves with regional programs and of promoting leadership in the rural development through solidarity-based environmental initiatives. These include the organizations Canapro Ambiental, Cooperación Verde and Cootregua, which have participated in and accompanied local environmental projects. This study has identified the common elements related to the principles of organizational design proposed by Elinor Ostrom as a result of the adoption of Corporate Social Responsibility (CSR) for the purpose of a sustainable growth. The above findings serve to corroborate the relevance of the principles of organizational design as a qualitative assessment methodology for environmental solidarity initiatives. In particular, the methodology demonstrates the value of supporting the objectives of environmental sustainability and governance in the long term, by means of the strengthening of Corporate Social Responsibility (CSR) for the purposes of the solidarity ecosystem.
