Published: February 2025

The structural damage repair of composite material is an important issue that needs to be addressed during the service life of composite materials. To investigate the effects of a scarf structure and scarf angle on the repair quality of composite material, this paper proposes a mixed-scarf (MS) repair structure that combines ramped-scarf (RS) and stepped-scarf (SS) repair structures. The effect of the repair structure on the mechanical properties was analyzed, as well as the quality of the adhesive interface. The results show that at a scarf angle of 10°, the repair efficiency and the quality of adhesive interface are better than that of scarf angles of 20° and 30°. At a scarf angle of 10°, the recovery degree of the flexural strength of the MS repair structure is 79.72%, which is 6.77% and 38.24% higher than that of the RS and SS repair structures, respectively. However, in terms of flexural modulus, regardless of repair structure, the flexural modulus is highest at a scarf angle of 20°. Furthermore, the impact strength of the MS repair structure is approximately 87.60% that of the RS repair structure; additionally, it exhibits an increase of 45.83% compared to the SS repair structure. Overall, the quality of the adhesive interface for the RS and MS repair structures is similar and better than that of the SS repair structure. In conclusion, the MS repair structure is well suited for small-angle scarf repairs, whereas the RS repair structure is more appropriate for large-angle repairs; in contrast, the SS repair structure demonstrates the least effective performance in terms of repair outcomes.

This in vitro study investigates the impact of the chemical modification of resin composite surfaces on repair bond strength of micro-hybrid resin composite material. First, 7 mm circular × 3 mm thick resin composite disks were prepared using teflon molds. Then, 50 specimens out of 100 were allocated for stimulated aging using a thermo-cycling (10,000 cycles) device. Both the 24 h and 1-year-aged composite discs were embedded in epoxy resin using a 2.5 cm wide × 1.5 cm thick circular mold. The surfaces were treated with Clearfil S3 bond alone or with the additional application of silane or porcelain primer. The other two groups were bonded with CRB bond with or without a porcelain primer. Using a teflon mold, a 2 mm circular and 3 mm high repair composite cylinder was built on the treated surfaces. The specimens were then stressed to de-bond by applying shear force to measure repair bond strength, and they were observed under the microscope to determine the failure pattern. The data were analyzed using SPSS26.0. Univariate analysis showed a significant effect (p = 0.013) of the bonding protocol on the repair bond strength; however, the effect of aging was insignificant (p = 0.170). The S3 bond with additional silane and the CRB bond showed the significantly higher repair bond strength of the 1-year-aged micro-hybrid composite. However, in case of 24 h aged specimens, the repair bond strength was statistically insignificant among the tested groups (p = 0.340). Chemical surface modification with silane has the potential to improve the repair bond strength of micro-hybrid resin composite materials.

Published: February 2025

Porous polymer membranes with highly interconnected open-cellular structure and high toughness are crucial for various application fields. Polymerized high internal phase emulsions (polyHIPEs), which usually exist as monoliths, possess the advantages of high porosity and good connectivity. However, it is difficult to prepare membranes due to brittleness and easy pulverization. Copolymerizing acrylate soft monomers can effectively improve the toughness of polyHIPEs, but it is easy to cause emulsion instability and pore collapse. In this paper, stable HIPEs with a high content of butyl acrylate (41.7 mol% to 75 mol% based on monomers) can be obtained by using a composite emulsifier (30 wt.% based on monomers) consisting of Span80/DDBSS (9/2 in molar ratio) and adding 0.12 mol·L−1 CaCl2 according to aqueous phase concentration. On this basis, polyHIPE membranes with high open-cellular extent and high toughness are firstly prepared via reversible addition–fragmentation chain transfer (RAFT) polymerization. The addition of the RAFT agent significantly improves the mechanical properties of polyHIPE membranes without affecting open-cellular structure. The toughness of polyHIPE membranes prepared by RAFT polymerization is significantly enhanced compared with conventional free radical polymerization. When the molar ratio of butyl acrylate/styrene/divinylbenzene is 7/4/1, the polyHIPE membrane prepared by RAFT polymerization presents plastic deformation during the tensile test. The toughness modulus reaches 93.04 ± 12.28 kJ·m−3 while the open-cellular extent reaches 92.35%, and it also has excellent thermal stability.

Published: February 2025

Pickering emulsions (PEs) can be utilized as inks for 3D food printing owing to their extensive stability and appropriate viscoelastic properties. This research explores food-grade PEs stabilized with nanoparticles (NPs) based on modified pea protein (PP) isolate and k-carrageenan (KC). NPs are fabricated from solutions with different concentrations of protein and polysaccharide and characterized in terms of size, zeta potential, and wetting properties. The composition of the emulsion is 60% sunflower oil and 40% aqueous phase. Nine emulsion formulations with varying PP and KC concentrations are investigated. The formation of hollow NPs with a hydrodynamic diameter of 120–250 nm is observed. Microscope imaging shows oil droplets surrounded by a continuous aqueous phase, forming homogenous PEs in all formulations that are stable for over 30 days. Further, the oil droplet size decreases with increasing NP concentration while the viscosity increases. Rheologic experiments portray elastic emulsion gels with thixotropic qualities ascribed to the presence of the polysaccharide. The emulsions are subjected to centrifugation in order to compare the original emulsions to concentrated PEs that possess improved capabilities. These emulsions may serve as sustainable and printable saturated fat alternatives due to their composition, texture, stability, and rheological properties. Lastly, PEs are printed smoothly and precisely while maintaining a self-supported structure.
Selective Multidimensional Particle Fractionation Applying Acoustic Fields
Authors: Sandmann Krischan , Fritsching Udo
Published: February 2025

The recent progress in the acoustic fractionation of particulate suspensions within microfluidic devices emphasizes the utility of the acoustic fractionation process also for gas-suspended particles as a significant advancement in the field of mechanical process engineering. In the literature, analytical and numerical studies have found the gas-based acoustic particle fractionation process to be suitable for particles in a size range below 10 µm. The viability remains experimentally unassessed. In this article, we present particle fractionation experiments conducted on gas-born particles suspended in high-intensity acoustic fields. A particle-size-dependent accumulation of particles in the acoustic sound velocity lobes and nodes could be observed, indicative of an acoustic fractionation process. Additionally, evidence of acoustic streaming and acoustic focusing has been found, both of which have the potential to impede the fractionation process. The experimental results align with the conclusions of numeric simulations. The in-process particle behavior is discussed in the context of the relevant literature and reinforces the notion of selective entrainment.

Authors: Craco Luis
Published: February 2025

Inspired by experiments manifesting unconventional metallic behavior in MoO2±δ and superconductivity in KxMoO2−δ, we present t2g-DFT+DMFT results for monoclinic MoO2. We unearth the role played by multi-orbital, many-particle physics in understanding the emergence of 4d-orbital selectivity with coexisting pseudogapped, resilient, and Fermi-liquid quasiparticles, which might host unconventional superconductivity in K-doped MoO2 bulk crystals at low temperatures. Our findings highlight the capability of DFT+DMFT to bridge the gap between electronic structure and electric transport in multi-orbital Hubbard models, providing insights into spin and charge fluctuations, as well as their role in orbital-selective non-Fermi liquid formation.
From the Church to the State and to Lordship

Published: February 2025

Despite a succession of advances and setbacks observed here and there, the suppression of regular religion in the age of revolution represented a definitive and irreversible process of the ascendancy of new social groups and classes and, at the same time, the suppression of the power of the two pillars of the ancien régime: the clergy and the nobility. It was also the nation that asserted itself as a “new historical actor”, with a new political and social agency of its own, and also with a new ambition for property and patrimony.
Can Reading the Life of a Self-Abusive Visionary Make Sense Today?
Authors: Frohlich Mary
Published: February 2025

The Autobiography of Saint Marguerite-Marie Alacoque recounts her many visions, ecstasies, and sufferings as she became God’s messenger, initiating the highly successful modern form of devotion to the Sacred Heart. Reading the Autobiography today is difficult, however. She constantly practices forms of obedience, self-control, and self-abuse that are offensive to today’s sensibilities. Her image of Jesus is as her “Master’ and “Sovereign” who desires and demands suffering on the part of those who love him. Her theology of the necessity of repairing God’s wounded honor by suffering is likewise outdated. Finally, the reliance of her message on visions does not inspire trust in an era that generally views visions as symptoms of pathology. This essay proposes that it is possible to discover authentic inspiration in the Autobiography by reading it with the help of several mediating theories. First, Hubert Hermans’ Dialogical Self Theory offers insight into traditional, modern, and postmodern styles of self-construction, thus situating Alacoque’s stories and practices within her time (at the cusp between traditional and modern styles) while offering a glimpse of how she can be understood within our time (at the cusp between modern and postmodern styles). Second, a historically contextualized eucharistic theology of embodied self-giving helps to see past the problematic elements of her theology. Finally, an ecotheological theory of visions suggests a way to understand her visions that may unveil their significance for our own time of crisis.
Deconstructing the Marginalized Self: A Homiletical Theology of Uri for the Korean American Protestant Church in the Multicultural American Context
Authors: Kim Jeremy Kangsan
Published: February 2025

This study explores the transformative potential of the traditional Korean concept of uri (we) and the Confucian principle of ren (compassion and resistance), integrated with the biblical tradition of lament, as a theological framework for addressing the marginalization of contemporary Korean American Protestant churches and their members. Critiquing the limitations of current theological models focused on marginality, the article reimagines the Korean American self through the lens of uri and ren. This perspective enables compassion and resistance to deconstruct the notion of the marginalized self and reconstruct an authentic identity. The article proposes a pastoral–prophetic homiletical praxis that fosters solidarity among Korean American churches and empowers these churches to claim their prophetic voice within the multicultural American context. This approach has the potential to transform Korean American churches into a space for hope, communal restoration, and resistance amid socioecclesial challenges.
Decentering Reformed Martyrdom from Calvin and the Martyrologies Through Bezan Sources
Authors: Bourgaux Aurélien
Published: February 2025

Martyrdom in the sixteenth-century French and Swiss Reformations has long been an exciting area of research for scholars. However, the subject has almost exclusively been studied through large collections called the “martyrologies” or through Jean Calvin’s writings, at the expense of other sources. The article first examines these historiographical trends and then addresses some critical issues of a martyrology—or a Calvin-centered approach. It provides some methodological tools to overcome such issues and advocates for considering alternative source bases that have been neglected thus far. The introduction to an ongoing survey around the figure of the poet and reformer Théodore de Bèze illustrates the range of possibilities. Decentering Reformed martyrdom would allow scholarship to better acknowledge its complexity and its corrigibility.
Nonlinear Seismic Signal Denoising Using Template Matching with Time Difference Detection Method
Authors: Xu Rongwei , Feng Bo , Wang Huazhong , Wu Chengliang , Nie Zhenbo
Published: February 2025

As seismic exploration shifts towards areas with more complex surface and subsurface structures, the complexity of the geological conditions often results in seismic data with low signal-to-noise ratio. It is therefore essential to implement denoising in order to enhance the signal-to-noise ratio of the seismic data. At present, the prevailing denoising techniques are based on the assumption that the signal adheres to linear model. However, this assumption is frequently invalid in complex geological conditions. The main challenge lies in the fact that linear models, which are foundational to traditional signal processing, fail to capture the nonlinear components of seismic signals. The objective of this paper is to present a methodology for the detection of nonlinear signal structures, with a particular focus on nonlinear time differences. We propose a method for detecting nonlinear time differences based on template matching, wherein the seismic wavelet is treated as the template. Template matching, a fundamental pattern recognition technique, plays a key role in identifying nonlinear structures within signals. By employing a local signal as a template, the template matching technique can identify all the structure of the signal, thereby enabling the detection of nonlinear features. By employing template matching, the nonlinear time differences in the signal are identified and corrected, thus enabling the signal to align with the assumption of linearity. Subsequently, linear denoising methods are employed to effectively remove noise and enhance the signal-to-noise ratio. The results of numerical experiments demonstrate that the proposed template matching method is highly accurate in detecting nonlinear time differences. Furthermore, the method’s efficacy in removing random noise from real seismic data is evident, underscoring its superiority.
An Enhanced Local Optimization Algorithm for GNSS Shadow Matching in Mobile Phones

Published: February 2025

In the context of mobile phones, the local optimal global navigation satellite systems (GNSS) shadow matching algorithm, which is based on the urban three-dimensional model, can effectively reduce the error of GNSS pseudo-range single-point positioning. However, the positioning accuracy of this algorithm is susceptible to noise, and its continuous signal-to-noise ratio (SNR) scoring method does not fully exploit the probability density and probability distribution information contained in the SNR. Therefore, this paper proposes two improvements for the local optimal shadow matching algorithm: (1) utilizing low-pass filtering to filter SNR, thereby reducing the influence of noise on the algorithm and (2) introducing a probability-based SNR scoring method to fully leverage the probability density and probability distribution information of SNR. In dynamic single-point positioning, the improved algorithm attains an absolute positioning accuracy of up to 3 m, representing a decimeter-level enhancement over the original algorithm. Experiments confirm that using the SNR statistical information of non-line of sight (NLOS) and line-of-sight (LOS) as prior information results in better positioning accuracy compared to when this information is distorted by multipath effects. Additionally, to address the issue of high time complexity in the shadow matching algorithm, especially when considering local optima, this paper presents a scheme to simplify the algorithm’s flow, reducing its time complexity by approximately 75%.

Authors: Wu Jianwei , Zhang Jiawei , Chen Yifan
Published: February 2025

Radar is utilized as an active sensing device across many fields. Its waveform optimization is responsible for target signature extraction, profoundly influencing the overall performance. First, the principle of pulse radar waveform design is explored. Waveform design strategies vary based on target models, whether point-like or extended ones, and are often formulated as high-dimensional, non-convex optimization problems with multiple constraints, such as energy, constant modulus, and sidelobe ratios. Second, to address them, techniques like alternating direction method of multipliers (ADMM), semidefinite relaxation (SDR), and minimization-maximization (MM) algorithms are widely employed. Finally, challenges in multimodal sensing collaborative detection, joint multi-tasking, sparse signal recovery, and intelligent perception highlight the need for innovative solutions to meet future demands.

Cannabis (Cannabis sativa L.) is one of the earliest cultivated crops and is valued for its medicinal compounds, food, fibre, and bioactive secondary metabolites. The rapid expansion of the cannabis industry has surpassed the development of production system knowledge. The scientific community currently focuses on optimising agronomic and environmental factors to enhance cannabis yield and quality. However, cultivators face significant challenges from severe pathogens, with limited effective control options. The principal diseases include root rot, wilt, bud rot, powdery mildew, cannabis stunt disease, and microorganisms that reduce post-harvest quality. Sustainable management strategies involve utilising clean planting stocks, modifying environmental conditions, implementing sanitation, applying fungal and bacterial biological control agents, and drawing on decades of research on other crops. Plant–microbe interactions can promote growth and regulate secondary metabolite production. This review examines the recent literature on pathogen management in indoor cannabis production using biocontrol agents. Specific morphological, biochemical, and agronomic characteristics hinder the implementation of biological control strategies for cannabis. Subsequent investigations should focus on elucidating the plant–microbe interactions essential for optimising the effectiveness of biological control methodologies in cannabis cultivation systems.

Accurately predicting the impacts of climate change on hydrological fluxes in ungauged basins continues to be a complex task. In this study, we investigated the transferability of the model parameters SCS-SMA-LR, available in the ATHYS platform, to simulate hydrological behavior within catchments of a large South Mediterranean transboundary basin, i.e., the Medjerda bordering Tunisia and Algeria, characterized by contrasting climatic and physiographic conditions. A robustness analysis was set up for donor and receptor catchments situated in the Medjerda catchment in Tunisia. The model was initially calibrated for two donor catchments, for the 127 km2 catchment of the Lakhmess watershed situated on the right bank and for the 362 km2 catchment of the Raghay watershed situated on the left bank of the Medjerda basin in Tunisia, using input data from 1990 to 1994. The model performance was evaluated through multiple accuracy criteria based on the Best Linear Unbiased Estimator (BLUE) for the automatic calibration to quantify the model simulation, proving its good performance. The temporal transferability was assessed by evaluating model performance, transferring the calibrated parameters for the two catchments as validation on data for 3-year periods outside the calibration domain to test the robustness of the model through a diachronic analysis from different decades, i.e., for the periods 1994–1997, 2001–2004, and 2014–2017, respectively. The spatial transferability was assessed by transferring the parameters calibrated on the donor catchments to be applied to the receptor catchments based on similarity and data availability. The model was upgraded to a greater catchment for data from 1994 to 2016 for the right bank, the Siliana Upstream catchment, and to the nearest catchment with a similar area for the data from 2008 to 2017 for the left bank of the Medjerda basin, the Bouheurtma catchment. The capacity of the soil reservoir and the flow velocity parameters proved to have an important impact on the modeling implementations at, respectively, 123.03 mm and 1 m/s for Raghay, and 95.05 mm and 2.5 m/s for Lakhmes. The results show that the space–time transfer process of model parameters produces an acceptable simulation of flow volumes and timing. The proposed methodology proved to be a successful way to monitor ungauged catchments and strengthens the robustness of the SCS-SMA-LR model for hydrological modeling and impact studies in ungauged basins of the Southern Mediterranean region.

Published: February 2025

A sinestesia pode ser amplamente definida como uma condição neurológica que causa uma mistura entre diferentes aspectos sensoriais sem relação entre si. Há uma grande dificuldade em padronizar uma definição única que inclua todos os mecanismos que a sinestesia comporta. Dessa forma, este trabalho teve como principal objetivo realizar uma introdução sobre as características gerais da sinestesia e discorrer sobre seus diferentes subgrupos, com foco principal na sinestesia para cores, contribuindo, assim, com a bibliografia em língua portuguesa. Como resultado, dividimos o trabalho em onze subcapítulos descritivos acerca dos principais tipos de sinestesia e identificamos que a definição geral é demasiado abrangente e, muitas vezes, deixa de lado características específicas. Entendemos que a escassez de voluntários com sinestesia pode causar alguns impedimentos para a realização de estudos mais robustos, mas, mesmo com todas as adversidades, o avanço nas pesquisas têm sido notório.

Introduction: Cannabis sativa threshing residue is the plant material left after extracting resinous trichomes from the dried female plant. This study examines the phytochemical properties of C. sativa threshing residue and screens its vasorelaxant, antimicrobial, and immunomodulatory activities. Methods: The residue was extracted sequentially using hexane, dichloromethane, ethyl acetate, and ethanol. The four fractions were analyzed by gas chromatography-mass spectrometry. Phenolic and flavonoid contents were estimated using Folin-Ciocalteu reagent and aluminum chloride colorimetric methods. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay determined in vitro antioxidant activity. The vasorelaxant effect was explored using rat mesenteric arterial beds (MABs). Antimicrobial studies on Salmonella enterica, Escherichia coli, Staphylococcus aureus, and Bacillus cereus were conducted using microdilution tests. Immunomodulatory activity was determined using cell proliferation, antibody production, and complement tests. Results: Phytochemical analysis of the four fractions revealed many volatile bioactive compounds, including terpenes like phytol and squalene and cannabinoids like delta-9-tetrahydrocannabinol and cannabidiol (CBD). The fractions had significant polyphenol and flavonoid content. They dose-dependently dilated the MAB and demonstrated varying DPPH free radical scavenging activity. Immunomodulatory activity showed an immunosuppressive effect on cell proliferation and biological functions. The four bacterial strains studied were sensitive to the fractions but with different degrees. Conclusion: Cannabis sativa threshing residue demonstrated diverse pharmacological potential, suggesting its suitability for developing cannabis-based medications targeting hypertension-related damage, free radicals, and bacteria, expanding its potential applications beyond inflammation-related conditions

Published: February 2025

Background: Developing chicken embryo culture techniques provides methods for manipulating chicken embryos. In this study, the cell-based approach investigated human Wharton’s jelly stem cells (HWJSCs) proliferation and migration into internal embryonic chick tissue. Methods: Wharton’s jelly cells were cultured on an acellular dermal matrix (ADM) and seeded on the chorioallantoic membrane (CAM) of a 4-day-old chicken embryo. Using an RT-PCR assay with the COLA-I human gene, molecular analysis was performed on chicken liver tissue after hatching to confirm the presence of these cells. Results: The chicken liver tissue from Wharton’s jelly stem cells/ADM sample tested positive for the human COLA-I gene. The COLA-I gene sequence analysis shows this sequence belongs to the COLA-I gene in humans. The cells cultured on CAM can migrate and proliferate in the liver of a chicken embryo. Conclusion: These findings suggest that human cells cultured on the CAM can appear in the liver of chickens. However, further investigations are necessary to confirm this finding.

Background: Kidney involvement is prevalent in systemic lupus erythematosus (SLE) and is the leading cause of disability and death. Colony-stimulating factor-1 (CSF-1) may be involved in the development of lupus nephritis (LN). This study aimed to evaluate serum CSF-1 levels in SLE patients with and without proteinuria and its correlation with the value of proteinuria. Methods: A total of 75 subjects including 25 newly diagnosed SLE cases without renal involvement evidence, 25 new SLE with biopsy-proven LN, and also, 25 healthy controls were included in the study. Serum CSF-1 level was measured in all participants using a human CSF-1 ELISA kit. Results: Analysis of variance (ANOVA) and post hoc analysis demonstrated significant differences between the three groups including healthy individuals, and SLE subjects with and without nephritis (P=0.006). The mean values of CSF-1 levels were increased among both participants without LN and patients with LN, compared to healthy individuals. However, a statistically significant greater mean concentration of CSF-1 was detected in individuals with LN compared to the healthy group (P=0.004). No significant statistical correlation was found between CSF-1 and 24-hour urine protein. Furthermore, when comparing the activity of SLE, a notable distinction was observed in the SLE disease activity index (SLEDAI) values between individuals with and without proteinuria (P<0.0001). Conclusion: An upward trend in average CSF-1 levels was observed among both patients with and without LN, in comparison to healthy individuals. Significantly enhanced concentrations of CSF-1 were found in subjects with LN compared to healthy individuals.
Arabization in the Context of Identity in a Globally-Immersed Culture: Challenges and Prospects
Authors: Elimam Fatima
Published: February 2025

This paper attempts to view the concept of Arabization -an issue gaining a higher consideration by educational policy makers in the Arab world- from a sociolinguistic perspective. A mixed method approach is adopted to investigate the pros and cons of Arabization. The study derives its conclusion based on previous studies on the one hand, and the evaluation of the common trends towards monolingualism in the Arab educational platforms on the other, observing the eminent sociocultural threats of globalization. While Brown’s theory of the inseparable connection between language and culture is used to prove the impossibility of calling for a lingual homogeneity in the presence of a globalized culture, Berry J.W.’s Acculturation theory is adopted to examine the nature of the cultural influence on the Arabs’ identity, and how can Arabs, though, ‘successfully’ live in a multicultural surrounding. It is not the aim of the research to relegate the role of Arabization in facilitating the teaching and learning processes in the various fields and educational levels; rather, it aims to draw the educational policy makers’ attention to protect the Arabs’ identity, not through carrying out linguistic policies alone, but by taking other decisions pertaining to the educational, cultural and social environment, as well. Some of the proposed measures include: reviewing syllabuses, enriching social and moral values, accelerating the scientific and technical translation activity, encouraging fair competition in varieties of scientific and literary activities where cultural diversity is wisely handled; and finally, providing free acculturation platforms as an attractive alternative to the social media platforms.

La presente investigación pretendió encontrar la relación entre el uso prolongado del computador y la presencia de síntomas propios del SVC, al igual orientar al trabajador frente a los riesgos derivados del uso de pantallas, la forma de prevenir, intervenir y tratar esta alteración. Para esto se entregó a las directivas de la Corporación Universitaria Minuto de Dios sedes Bucaramanga una guía o manual de información importante relacionada con el manejo responsable del computador y la pertinencia de realizar descansos visuales periódicos que refresquen y relajen los ojos.

Se realizó una revisión bibliográfica relevante para el tema de la investigación con el fin de comprender términos relacionados con la estructura del ojo, afecciones que pudieran alterarla, además de ahondar en conceptos propios de síndrome que permitieran trazar y cumplir con los objetivos propuestos.

Determinado lo anterior, se escogió como instrumento de valoración la encuesta, esta constaba de 22 preguntas la cual fue aplicada a una muestra de 33 trabajadores en la cual se profundizaba acerca de su comportamiento habitual frente al computador y la utilización del mismo.

Del análisis de los resultados obtenidos se pudo establecer subjetivamente la presencia de síntomas propios del SVC, esta información se correlacionó con los resultados de los exámenes optométricos buscando información más objetiva con la cual se confirmaron los síntomas.

Debido al crecimiento desmesurado de empresas en el sector construcción en el Perú y los innumerables accidentes sucedidos en las empresas constructoras, adicionalmente existe poca preocupación de parte de los gerentes respecto a mantener una cultura de seguridad laboral en sus empresas, se hace necesario realizar el presente trabajo cuyos objetivos fueron identificar la relación de la conducta laboral con la seguridad en el trabajo en las empresas constructoras, establecer el tipo de conducta de los trabajadores y el nivel de seguridad en el trabajo. Para lo cual se contactaron con 74 empresa y se entrevistó a 917 trabajadores, utilizaron los cuestionarios propuestos por Aguilar, De Lille, Escamilla & Cetina, (2018) para medir conducta labora y una adaptación del cuestionario elaborado por Gómez, Silva, Vilaret, & Suasnavas (2016) en materia de seguridad en el trabajo, ambos instrumentos pasaron por la validación de contenido mediante tres expertos y la fiabilidad con el alfa de Cronbach. Se realizó la prueba de normalidad mediante Kolmogorov-Smirnov, obteniendo un p<0.05, la cual demuestra que ambas variables no tienen distribución normal, posteriormente mediante el Rho de Spearman = 0.549 y un valor de sig. 0.00**. Las conclusiones fueron: existe una relación positiva moderada entre la conducta laboral y seguridad en el trabajo en empresas constructoras, los trabajadores tienen una percepción negativa de la conducta laboral y el nivel de seguridad en el trabajo.

Published: February 2025

: Este estudio se orienta a las interpretaciones del modo de vida de los pobladores de la localidad de Sierra Chica, partido de Olavarría, en el período comprendido desde 1850 y fines del siglo XIX, sumado al relevamiento arqueológico y al análisis del material cultural producto de sus múltiples actividades. En la campaña arqueológica de 2013 se produce el hallazgo en estratigrafía de una estructura de piedra como posible acueducto o estructura hidráulica y su relación con la distribución de diversos muros de piedra, canteras, líneas de postes, en el sitio Gregorini 1 (SG1), en el paraje “combate de Sierra Chica de 1855” y los sitios Sierra Chica (SCH), Sierra Chica A (SCHA, Sierra Chica B (SCHB) y Molino Viejo (SMV). Esto permite reforzar propuestas del ámbito de la denominada arqueología en momentos históricos: las huellas del trabajo en diversas rocas, su relación en el paisaje con las canteras, la minería local, la explotación de los recursos naturales, especialmente las fuentes de agua y los asentamientos en antiguos canales del arroyo. Todo esto nos aproximó a proponer la prospección arqueológica de posibles sitios de aprovisionamiento de materias primas líticas en un lugar monumentalizado como “Combate de Sierra Chica de 1855”. La propuesta analiza diversos temas desde una mirada macro de los modos de actividad de los pobladores relacionados con los aportes de la arqueología de la arquitectura, del paisaje y de la etnohistoria, centrados en momentos de la consolidación del Estado Nación a finales del Siglo XIX, en la (“frontera del desierto” y de la inmigración eurocriolla, marco ambiental en el cual tuvieron lugar diversas tácticas y estrategias humanas.

The degradation generated by plasma treatments of the dye Permalon Rhodamine B in aqueous solution (123 mg/L) was evaluated. The degradation was quantified as a function of the exposure time (240 min) and the plasma generation current (20.0, 30.0, 40.0 and 50 mA) at a voltage of 2000 V. The changes (degradation) were monitored by Chemical Oxygen Demand (COD) and Total Organic Carbon (TOC). Total dissolved solids (TDS) and electrical conductivity (EC) were also measured. The degradation of the dye in terms of TOC in the solution was maximum (97 %) for the 50 mA plasma treatment. As the current increases, the COD in the solution also increases. For the 50 mA treatment, the COD increased by 27%. The TDS and EC increased as the exposure time increased. The higher the current and exposure time, the greater the degradation of the dye

In this paper, we present the results of the campaign #detengo el #cyberbullying en la #universidad to generate knowledge about the issue and its consequences when a person suffers it, as well as the ways to report it. A methodology based on the analysis of social network metrics was applied. The social network used for the campaign was X because it is among the ten most used in Mexico. The results show that videos cause a more significant number of impressions and that 100% of the people who interacted with the campaign content do not know how to report cyberbullying. Likewise, there was no evidence of the generation of knowledge or awareness, so it is not possible to say if this campaign prevented or reduced this crime. However, it has been a favorable means to inform people about the issue. In this sense, we seek to implement strategies to estimate whether this campaign can generate knowledge to change behavior to prevent, reduce, eradicate, or encourage reporting it.

At the Fidel Velázquez Technological University (UTFV), the congestion of students at door 4 pedestrian access has caused delays and inconveniences. This project proposes the installation of a pedestrian access control system that consists of the installation of 3 turnstiles at the three doors of the university integrated with a barcode scanner for the student community's credentials. The main objective is to expedite the entry of students to improve efficiency in the institution. En la Universidad Tecnológica Fidel Velázquez, la aglomeración de estudiantes en la única puerta de entrada con dos accesos ha generado retrasos y molestias. Este proyecto propone la instalación de torniquetes en tres accesos específicos para distribuir mejor el flujo de estudiantes. Se implementará un sistema de código de barras en las credenciales de los estudiantes, con escáneres en los torniquetes para habilitar el acceso. El objetivo principal es agilizar el ingreso de alumnos para mejorar la eficiencia en la institución.
