Energy Conservation Laws and Their Relation with Time Dilation
Authors: Quattrini Stefano
Published: November 2024

Atomic clocks are crucial in understanding the connections between electrodynamics and gravitation. To this purpose a revisitation of a well-known derivation of Schiff, about variation of period of atomic clocks, is performed. The Weak Equivalence Principle and Special Relativity are found not sufficient to derive, from Schiff’s proposal, gravitational time dilation, even to a first order approximation. Schiff’s derivation of time dilation in absence of gravitation, can match, to all orders of approximation, relying on conservation of energy, the one derived in static gravitation. Energy conservation and WEP bridge the two interactions, such that, variations of periods of oscillators on Earth depend on their kinetic energy and potential energy, referred to the Earth-Centered Inertial frame.

Industry 5.0 integrates green technology with sustainability, focusing on supplier-customer interaction and knowledge spillovers. It optimizes resource efficiency, circularity, and social responsibility. Robotics enhance capabilities without replacing human labor, and organic agriculture standards and robotics in the wine industry meet consumer demand. The research explores the adoption of these directional and applicative elements under the Triple Bottom Line (TBL) strategy in Romania and Portugal's wine industry, highlighting its potential for sustainability and environmental protection.The study analyzed data on wine indicators: wine consumption, cultivated vineyard area, grape production, volume of wine produced, and value of exports for Romania and Portugal from the International Organization of Vine and Wine (OIV) and the World Trade Map, providing an overview of the wine industry in Romania and Portugal. The data provides insights into the global market performance of Romanian and Portuguese wines, allowing for a comparative evaluation of production capabilities, domestic consumption dynamics, and export competitiveness. It also identified trends and shifts in the wine industry over time. We designed an ANOVA analysis to test if there are significant differences between Romania and Portugal regarding wine indicators. Through an SEM SmartPLs path analysis, we tested the influence of main factors on the value collected from wine export.

Background/Objectives: The physiological basis underlying symptomatic versus asymptomatic premature ventricular contractions (PVC) remains poorly understood. However, symptomatic PVC can significantly impair quality of life. In patients without structural heart disease, symptom intensity is crucial for guiding management strategies and determining the need for medical or surgical intervention. In this study, we aimed for the first time to examine the associations be-tween PVC symptoms and cardiac interoception. Methods: The study included 34 participants with PVC (20 women; median age = 42 years; 17 participants had asymptomatic PVC) without concomitant disorders. Interoception was assessed through interoceptive accuracy (IA) probed by two behavioral tests—mental tracking (MT) and heartbeat detection (HBD)—and the neurophysi-ological marker of cardiac interoception, the heartbeat-evoked potentials (HEPs). Symptom inten-sity scores reported by patients served as the response variable in the regression analysis, with IA and HEP as predictors. Other factors such as sex, age, percent of body fat, trait anxiety, and alexithymia were added to the models as confounding variables. Results: IAMT was significantly higher in patients with symptomatic PVC. IAMT and HEP modulation for the HBD task were asso-ciated with symptom intensity. A combined regression model incorporating both metrics showed the highest predictive accuracy for symptom severity. Adding confounding variables improved model quality (lower AIC); however, only the male sex emerged as a significant negative predictor for symptom intensity. Conclusions: Our findings confirm a significant association between in-teroception and PVC symptom severity. Integrating behavioral and neurophysiological interocep-tion measures enhances symptom prediction accuracy, suggesting new ways to develop diagnos-tic and non-invasive treatment strategies targeting interoception in PVC management.
Constrained Underdiagonal Paths and pattern Avoiding Permutations
Authors: Frosini Andrea , Guerrini Veronica , Rinaldi Simone
Published: November 2024

We show a simple bijection $P$ between permutations $S_n$ of length $n$ and underdiagonal paths of size $n$, the last being lattice paths made of up $U=(1,1)$, down $D=(1,-1)$, west $W=(-1,1)$ steps, running from $(0,0)$ to $(2n,0)$, and such that: (1) the path is weakly bounded by the lines $y=0$ and $x=y$; (2) a $D$ (resp. $W$) step cannot be followed by a $W$ (resp. $D$) step.

The aim of this paper is to study and enumerate families of underdiagonal paths which are defined by restricting the bijection $P$ to subclasses of $S_n$ avoiding some vincular patterns.
For a given pattern $\tau$, let $S(\tau)$ be the family of permutations avoiding $\tau$, and $P(\tau)$ the family of underdiagonal paths corresponding to permutations in $S(\tau)$, precisely $P(\tau)=\{ P(\pi): \pi \in S(\tau) \}.$

We will consider patterns $\tau$ of length $3$ and $4$, and, when it is possible, we will provide a characterization of the underdiagonal paths of $P(\tau)$ in terms of geometrical constrains, or equivalently, the avoidance of some factors. Finally, we will provide a recursive growth of these families by means of generating trees and then their enumerative sequence.

Published: November 2024

Kidney cancer has become a major global health issue over time, showing how early detection can play a very important role in mediating the disease. Traditional histological image analysis is recognized as the clinical gold standard for diagnosis although it is highly manual and labor-intensive. Due to this issue, many are interested in comput-er-aided diagnostics technologies to assist pathologists in their diagnostic. Specifically, deep learning (DL) has become a viable remedy in this field. Nonetheless, the capacity of existing DL models to extract comprehensive visual features for accurate classification is limited. Towards the end, this study proposes using ensemble models that combine the strengths of multiple transformers and deep learning model architectures. By leveraging the collective knowledge of these models, the ensemble enhances classification perfor-mance and enables more precise and effective kidney cancer detection. This study compares the performance of these suggested models to previous studies, all of which used the publicly accessible Dartmouth Kidney Cancer Histology Dataset. This study showed that the Vision Transformers, with an average accuracy of over 99%, were able to achieve high detection accuracy across all complete slide picture patches. In particular, the CAiT, DeiT, ViT, and Swin models outperformed ResNet. All things considered, the vision Transformers consistently produced an average accuracy of 98.51% across all five folds 5 folds. These results demonstrated that Vision Transformers might perform well and successfully identify important features from smaller patches. Through utilizing histo-pathological images, our findings will assist pathologists in diagnosing kidney cancer, resulting in early detection and increased patient survival rates.
The Solution to the Crisis in Cosmology: Current Cosmology is a Distorted Internal View of a Uniformly Expanding Spherical Universe
Authors: Krajcar Valter Josip
Published: November 2024

Today's Lambda Cold Dark Mater (ΛCMD) cosmology model is in crisis and requires a new Kuhn paradigm. This new paradigm is presented here, analogous to shift from geocentric to a heliocentric system. All our cosmological measurements are measurements INSIDE (IN) the universe, not OUTSIDE (OUT) of space-time. This is not a trivial observation, because (IN) measurements gives a distorted picture of a simpler, true (OUT) cosmology. ΛCDM cosmology is a distorted internal view of the (OUT) spherical, linearly expanding universe using Brans-Dicke's theory generalization: Self Creating Cosmology (SCC). This (OUT) SCC model reproduces (IN) ΛCDM cosmology parameters: the ratio of matter to dark energy, the equation of the dark energy state, the time of dark energy dominance, and the value of today's acceleration. In SCC cosmology model Ωk = (-1/12), but like some cosmic “mimicry” a spherical universe “pretends” to be flat from INSIDE view. The predicted theoretical ratio of radial to transverse distance is 1.0847 for z = 1089.8, compared to experimental ratio H0(SNe)/H0(CMB) = 1.0858 ± 0.0127. This same ratio solves the S8 tension. The unexpectedly early appearance of various structures detected by JWST for large redshift is caused by incorrectly determined relation of t(z).

Published: November 2024

The European Union’s (EU) Corporate Sustainability Reporting Directive expanded its Non-Financial Reporting Directive requirements to companies with over 250 employees, mandating their sustainability reporting from 2025. This expansion will exceed the number of companies subject to mandatory reporting, presenting new challenges for managers and responsible employees. Companies will have to report according to the European Sustainability Reporting Standards. The Erasmus+ project "Smart Education for Corporate Sustainability Reporting" (SECuRe) addressed gaps in vocational education and training (VET) programs related to sustainability knowledge and reporting. It aimed to establish a unified approach for VET teachers and learners across the EU, preparing them for the evolving job market demands. The project began by developing a knowledge repository and questionnaire, focusing on current reporting practices and job requirements, and continued with the preparation of materials for the training course. The course encompassed six learning units: 1) European legislation and sustainability standards, 2) sustainability management, 3–5) environmental, social, and corporate dimensions, and 6) sustainability reporting. The initiative included multiplier events, pilot applications, and course online tests. To deliver the course effectively, the project utilized an interactive e-learning platform with gamification elements and other engaging activities to enhance learning outcomes.

Authors: Sangoi Kevin , Nadimi Mahdi , Song Jie , Fu Yao
Published: November 2024

This work examines the effects of various heat treatments on the microstructural characteristics and corrosion resistance of 316L stainless steel fabricated by L-PBF. The microstructural evolution and corrosion properties at different heat treatment temperatures (500°C, 750°C, and 1000°C) were assessed by utilizing electron backscatter diffraction (EBSD), transmission electron microscopy (TEM), and electrochemical polarization tests. It has been found that increasing heat treatment temperature significantly alters the grain size, reduces dislocation density, and impacts corrosion resistance of the material. The melt pool boundaries, visible in the as-fabricated samples, begin to fade at 750°C. Corrosion tests demonstrate a decrease in pitting and repassivation potentials with increased heat treatment temperature, suggesting a deterioration in the material's resistance to pitting corrosion. The study highlights the complex relationship between heat treatment conditions, microstructural evolution, and corrosion resistance in 316L stainless steel, deepening understanding of processing-structure-property relationships in additively manufactured metals used in corrosive environments.

Published: November 2024

Metal hydride hydrogen compressors have attracted great attention due to their reliable safety, environmental friendliness, and the absence of vibration and noise. Herein, the effects of Ti substitution for Zr on the crystal structure and hydrogen comprehensive performance of Ti0.92+xZr0.1-xCr1.0Mn0.6Fe0.4 (x = 0, 0.01, 0.02, 0.03) are investigated systematically. Among the investigated alloys, the Ti0.94Zr0.08Cr1.0Mn0.6Fe0.4 alloy can be considered as a promising candidate for application with a hydrogen capacity of 1.82 wt.% under 9 MPa at -10 °C. Meanwhile, it exhibits excellent hydrogen absorption kinetic performance, reaching 1.655 wt.% in 5 min. The desorption pressure at 83.9 °C is determined to be 25 MPa by Van't Hoff fitting plots, which fulfills the requirement of producing over 25 MPa hydrogen pressure in water-bath environments with a high compression ratio of 3.08. The Ti0.94Zr0.08Cr1.0Mn0.6Fe0.4 alloy is very promising for hydrogen refueling applications in long tube trailers and low-pressure gas cylinders.

Authors: Val Sonia , Lambán María Pilar , Lucia Javier , Royo Jesús
Published: November 2024

Milling machines remain of great importance in modern manufacturing, with tool optimization playing a significant role in cost reduction. Insert-compound cutting tools can reduce the cost of operations by optimizing their lifespan. Subsequently, an accurate prediction of insert wearing is essential. This article analyses the wear of cutting tools in milling machines, focusing on accu-rately predicting their lifespan using artificial intelligence algorithms. The study highlights how artificial intelligence, through various models, has greatly improved the precision of wear pre-dictions, surpassing the results of prior studies. Results obtained from the dataset of an insert tool, which are widely used today, can be extrapolated to other milling inserts. The results demonstrate the progression of tool wear over time under varying cutting parameters, providing critical insights for optimizing milling operations. By analyzing this wear, the system can alert the machine operator when it is necessary to replace the cutting insert before failure occurs, thereby preventing suboptimal workpiece quality. This proactive approach not only enhances operational efficiency and reduces the overall cost of production but also minimizes the need for continuous supervision, contributing to more streamlined and autonomous machining processes.

Published: November 2024

Background:Gastrointestinal tract cancers account for approximately one-third of cancer-related deaths. Early diagnosis and effective treatment are the most important ways to prevent cancer-related morbidity and mortality. ROMO1 has been shown to play an important role in many types of cancer. However, the biological function of ROMO1 is still poorly understood in gastrointestinal system cancers. The aim of this study is to reveal the expression change and oncogenic role of ROMO in gastrointestinal system cancers. Methods:Gene Expression Profiling Interactive Analysis (GEPIA), UALCAN, TIMER, GeneMANIA, TISIDB and STRING were applied to assess the biological function of ROMO1 in gastrointestinal cancers (Colon adenocarcinoma (COAD), Esophageal carcinoma (ESCA), Liver hepatocellular carcinoma (LIHC), Pancreatic adenocarcinoma (PAAD), and Stomach adenocarcinoma (STAD)). Results:ROMO1 is significantly increased in gastrointestinal cancers and overexpression of ROMO1 was associated with clinicopathological features. In addition, ROMO1 has been found to be closely associated with between tumor-infiltrating immune cells in gastrointestinal cancers. ROMO1 is closely related to the inner mitochondrial membrane proteins (TIMM) family. Conclusison: The study revealed that ROMO1 is of significant clinical importance for gastrointestinal cancers and may have potential clinical utility in treatment and prognosis.

Authors: Scendo Mieczysław , Żórawski Wojciech
Published: November 2024

The corrosion resistance of a Cr3C2-25(Ni20Cr) cermet coating applied to an Al7075 substrate (Cr3C2-25(Ni20Cr)/Al7075) was investigated. The coating was produced by cold spraying (CS). To improve its properties, the coatings were annealed at 100°C, 300°C, and 500°C for 24 hours in air. The mechanical properties of the Cr3C2-25(Ni20Cr)/Al7075 composite were assessed through microhardness (HV) meas-urements. The surface morphology and microstructure of the specimens were examined using a scanning electron microscope (SEM). Electrochemical testing in an acidic chloride solution was employed to evalu-ate the corrosion behavior of the materials. The cermet coating effectively protected the Al7075 substrate from the aggressive corrosive environment. Heat treatment homogenized the structure of the cermet coat-ing, eliminating microcracks and pores on the Cr3C2-25(Ni20Cr)/Al7075 surface. Notably, annealing at 300°C in air significantly enhanced the corrosion resistance of the cermet coating. The corrosion rate was reduced by more than five times compared to the non-heat-treated Cr3C2-25(Ni20Cr)/Al7075 coating.

Authors: Largo Prisca , Arnone Olivia C. , Sacco Francesco , Cantalupo Gaetano , Biban Paolo
Published: November 2024

Background and Clinical Significance: Acute necrotizing encephalopathy (ANE) represents a severe complication of influenza virus infection, mainly described in children. We report the cases of two young girls with ANE associated with influenza virus infection, diagnosed by MRI cerebral scan. Case Presentation: A 7-year-old girl with a history of a previous episode of ANE presented with a worsening soporous state and seizures. In the second case, an otherwise healthy 5-year-old girl presented with fever, seizures and marked neurological deterioration. In both cases, nasopharyngeal swab testing was positive for influenza virus A, while cerebral MRI indicated ANE. Despite aggressive treatment with high-dose corticosteroids and a five-day course of immunoglobulins, the ultimate prognosis was poor in both patients. ANE is a serious complication of viral infections in children, with a high mortality rate and a broad spectrum of neurological sequelae. To date, the pathophysiology and management of influenza virus-induced ANE remain uncertain. Although ANE is usually sporadic, familial and recurrent cases have been reported, and a RANBP2 mutation has occasionally been associated. Conclusions: Rapid recognition of neurological symptoms and suspicion of a viral trigger, especially in influenza-like illnesses, are both essential for the timely administration of effective therapy. Further research is needed to clarify the pathophysiology of ANE and establish the best therapeutic strategies to fight such a deadly disease.
Per- and Polyfluoroalkyl Substances (PFAS) as Emerging Obesogens: Mechanisms, Epidemiological Evidence, and Regulatory Challenges

Published: November 2024

The pervasive presence of per- and polyfluoroalkyl substances (PFAS) in the environment and their persistent nature raise significant concerns regarding their impact on human health. This review delves into the obesogenic potential of PFAS, shedding light on their mechanisms of action, epidemiological correlations with obesity and metabolic disorders, and the challenges faced in regulatory frameworks. PFAS, characterized by their carbon-fluorine chains, are ubiquitous in various consumer products, leading to widespread exposure through ingestion of contaminated food and water. Emerging evidence suggests that PFAS may act as endocrine-disrupting chemicals, interfering with lipid metabolism and hormone functions related to obesity. We examine in vitro, in vivo, human, and in silico studies that explore the interaction of PFAS with peroxisome proliferator-activated receptors (PPARs) and other molecular targets, influencing adipogenesis and lipid homeostasis. Furthermore, the review highlights epidemiological studies investigating the association between maternal PFAS exposure and the risk of obesity in offspring, presenting mixed and inconclusive findings that underscore the complexity of PFAS effects on human health. Presently, there are major challenges in studying PFAS toxicity, including their chemical diversity and the limitations of current regulatory guidelines, potential remediation, and detoxification. This review emphasizes the need for a multidisciplinary approach, combining advanced analytical methods, in silico models, and comprehensive epidemiological studies, to unravel the obesogenic effects of PFAS and inform effective public health strategies.

Published: November 2024

In 2022, an outbreak of H5N1 highly pathogenic avian influenza (HPAI) killed 60% of the largest breeding colony of Dalmatian pelican (DP) in the world, at Mikri Prespa Lake (Greece), prompting a multidisciplinary study on HPAI and other pathogens. This study determines the antimicrobial resistance rates of cloacal enterococci and Escherichia coli in DPs. Fifty-two blood and cloacal swab samples were collected from 31 nestlings (20 DP/11 great white pelicans) hatched after the H5N1 outbreak at the Prespa colony and 21 subadult/adult DPs captured at a spring migration stopover. Swabs were inoculated in non-selective and chromogenic selective media. Identification was performed by MALDI-TOF, and antimicrobial susceptibility was tested. The genetic content was characterized by PCR-sequencing and the clonality of extended-spectrum-betalactamase (ESBL)-producing-E. coli isolates by Multi-Locus-Sequence-Typing. Twenty-eight non-repetitive E. coli and 45 enterococci isolates were recovered in non-selective media; most of them were susceptible to all antibiotics tested (85.7% E. coli/91.1% enterococci). Three of 52 samples (6%, all adults) contained ESBL-E. coli isolates (detected in chromogenic ESBL plates), all carrying the blaCTX-M-15 gene and belonging to the lineage ST69. Despite the susceptibility of most fecal E. coli and enterococci isolates to all antibiotics tested, the identification of E. coli of lineage ST69 carrying blaCTX-M-15 is of concern. This high-risk clone needs further investigation to elucidate its primary sources and address the growing threat of antimicrobial resistance from an integrated 'One Health' perspective. Furthermore, it is imperative to further study the potential impacts of ESBL-E. coli on the endangered DP.

Published: November 2024

Introduction: In preeclampsia (PE), impaired trophoblast proliferation and differentiation are thought to cause abnormal placentation and subsequent clinical manifestations of the disease—i.e., hypertension, proteinuria, and end-organ damage. Insulin-like growth factor 1 (IGF-1) influences trophoblast cell function, however the mechanisms of IGF-1’s action on trophoblasts is not well understood. Inhibitor of DNA binding protein 2 (ID2) is involved in trophoblast differentiation and implicated in many processes disrupted in PE including placental development, vascular differentiation, and angiogenesis. We hypothesized that IGF-1 regulates trophoblast proliferation and differentiation via ID2.
Methods: Immortalized human first trimester trophoblast cells (HTR-8/SVneo) were treated with IGF-1 for 24 hours after serum starvation. ID2 mRNA and protein were measured, as well as trophoblast cell viability, proliferation, tube formation and migration.
Results: IGF-1 decreased ID2 expression in a dose-dependent manner. IGF-1 decreased trophoblast proliferation but increased cell viability, differentiation, and migration. ID2 overexpression mitigated the effects of IGF-1 on trophoblast cells.
Discussion: These data suggest IGF-1 could regulate trophoblast proliferation and differentiation through ID2. Dysregulation of ID2-mediated IGF-1 signaling in trophoblast cells could be involved in the pathogenesis of pregnancy disorders like uterine growth restriction and PE.

Published: November 2024

This work evaluated the inclusion of seaweed in artificial diet of Paracentrotus lividus sea urchins weighing between 11 and 14 g to test its effect on growth and gonadal yield. Initially, multiple-choice feeding preference assays were conducted using 20% fresh and dried specimens of Laminaria digitata, Sargassum muticum, and Ulva lactuca seaweeds incorporated into an artificial diet. Then, over the course of 20 weeks, experiments comprised of four different diets were carried out, including one for each seaweed incorporated into the artificial diet. Afterwards, sea urchins were weighed to evaluate somatic growth. From the eighth week onwards, animals were selected for gonadosomatic index and gonad coloration analyses. In the feeding preference test, fresh and dried L. digitata showed the best results. In test with seaweed incorporated into the artificial diet, the preference was for diets containing L. digitata and S. muticum. Both diets also promoted a higher gonadosomatic index than that of the control at the end of the experiment. Therefore, it can be concluded that the inclusion of L. digitata and S. muticum in the artificial diet of sea urchins can act as a food stimulant to improve growth performance.

Case:

A 42-year-old woman presented with lateral chest and back pain. She was referred to our hospital after magnetic resonance imaging revealed a thoracic spine lesion. The initial examination revealed no obvious neurological deficits. A biopsy was performed, and enzyme-linked immunosorbent assay and western blotting confirmed Echinococcus infection. Paralysis and paresthesia developed, and stabilization and albendazole treatment were initiated. Postoperatively, the paralysis improved, and 2 years later, there was no lesion progression or symptom recurrence.

Conclusions:

Lesion resection is ideal for spinal echinococcosis; however, when resection is difficult, posterior stabilization and antiparasitic drugs may be effective.

Published: November 2024

Indonesia is a country with a high risk of earthquakes. Earthquake vibrations can cause ground shifts, which, in turn, affect building structures. To assess the level of risk for building damage, it is necessary to conduct a collapse scheme analysis and seismic performance evaluation of buildings. In this study, the author examined one of the earthquake-prone areas, Sawahlunto City, located in West Sumatra Province, Indonesia. The focus of the research is Block B of the Sawahlunto Market, a building that serves as a hub for community economic activities. The analysis employed is pushover analysis. The research methods include data collection, load calculations, 3D modeling, and static pushover analysis. Structural modeling was carried out using SAP2000 software. The structural performance level was evaluated based on SNI 1726-2019 and ATC-40 standards, and the mechanism of structural collapse was analyzed using plastic hinge formation. The analysis results show that the capacity curves in the X and Y directions have almost identical shapes, indicating that the structural stiffness along both axes is nearly the same. The performance points in the X and Y directions classify the building structure under the immediate occupancy category. This indicates that the building is highly capable of withstanding earthquakes with no significant damage.

This paper aims to explore the impact of SPCO 2013 on Islamic Education in Brunei. Therefore, this study discusses the Brunei education system prior to and since the implementation of the SPCO 2013 and aims to provide a critical analysis of the action taken by the Brunei government to bring about changes in both its secular and religious schools. Mixed methods research is used to make more rigorous inferences about the research problems. Interviews have been conducted with the respective government officers for data collection. The data were collected and then analyzed using the thematic analysis technique, followed by descriptive quantitative analysis. The findings of this study indicate that the SPCO 2013 has had a significant impact on the Brunei Education Curriculum in both of its Public Schools and Religious Schools. Therefore, the findings conclude that curriculum revision was crucial to ensure that it was in line with Islamic teachings and did not contain any elements that contradicted Shariah law, and this also helps to promote awareness and avoid misconception of the SPCO 2013 among non-Muslim students who are an integral part of the Brunei society.
DECONSTRUCTING TAPHONOMY TO RECONSTRUCT THE MORPHOLOGY AND LIFE HABIT OF ATTENBORITES JANEAE AT NILPENA EDIACARA NATIONAL PARK
Authors: Mccandless Heather K. , Droser Mary L.
Published: November 2024

Attenborites janeae is a soft-bodied, enigmatic member of the Ediacara Biota with variable internal and external morphology. This taxon is only found within the Ediacara Member of South Australia at Nilpena Ediacara National Park. It occurs rarely across this site but over 100 specimens occur on a single bedding plane, TB-ARB. Previous research has suggested that fossils of Attenborites represent a taphonomically altered form of the true organism which may have been pelagic. Here we use a combination of morphologic and taphonomic methods to reconstruct the most likely morphology and life habit of Attenborites janeae. Evaluating the characteristics of each fossil and the broader bed population, we find that the variable morphology among Attenborites specimens is a product of biostratinomic collapse and that these fossils represent the deflated form of living organisms that were most likely globose and radially symmetrical. We employ the 3D modeling software Blender to conduct inflation simulations on laser-scanned meshes of each fossil to reconstruct the original morphology. To determine the most likely life habit of Attenborites, we examine the broader sedimentological and preservational context of the taxon. We find a pelagic life habit most parsimonious, consistent with the original hypothesis and the reconstructed morphology, rendering Attenborites the only Ediacara taxon to be supported as pelagic based on both taphonomic and morphological evidence.
Resettling and reshaping social ecology: Social stratification and exploitation practices in Mahaweli resettlement area in Sri Lanka

Published: November 2024

The Sri Lankan government places a high priority on rural development, as a majority of the population living below the poverty line resides in rural areas. Progress is hindered by limited accessibility and resources. Resettlement was used as a strategy to improve the living conditions of the people. New resettlement practices have brought about significant changes in communities, shifting from traditional to modern social systems. This study investigates the emergence of social stratification and their role in facilitating exploitation practices in the Mahaweli resettlement scheme, utilizing sociological theory to understand stratification and inequalities. The study focuses on the social stratification and exploitation patterns in resettlement areas, using a literature review and qualitative data analysis to explore the mode of production, synthesis of social stratification, examination of exploitation among different social strata, and rationalization of exploitation within these areas. External interventions have led to the establishment of social stratification in the resettlement areas, but the strict state administrative framework has posed challenges in maintaining autonomy and establishing a self-reliant social and economic system. Consequently, poverty levels in these regions have increased due to the emergence of new social hierarchies and exploitation in various ways underscoring the need for more comprehensive and effective resettlement initiatives.

Objetivo: En 2022 el Perú aprobó una norma técnica del odontograma, que estandariza la información en la historia clínica para fines legales de los usuarios y responsabilidad del profesional. El propósito del estudio fue determinar el conocimiento de los odontólogos sobre la norma técnica del odontograma en odontólogos. Materiales y Métodos: Este estudio observacional transversal se realizó en una muestra de 187 odontólogos (116 docentes y 71 estudiantes de posgrado) de 22 a 62 años (65,5% mujeres, edad media 38,22 ± 12,19) de una universidad privada en Lima. Un cuestionario de 30 preguntas valorado de 0 a 30 puntos se distribuyó proporcionalmente en tres dimensiones: hallazgos clínicos (D1), disposiciones (D2) y terminología (D3). Datos demográficos de edad, sexo, tipo de participante/estudio y tiempo de experiencia profesional fueron incluidos. El cuestionario pasó la validación por constructo con análisis factorial exploratorio (Kaiser-Meyer-Olkin=0,5; Bartlett<0,000) y la confiabilidad de consistencia interna (KR-20=0,78). Las pruebas de correlación de Pearson, T de Student y Anova de una vía con post-hoc de Tukey se utilizaron con un P<0,05. Resultados: El puntaje de conocimiento fue de 19,96 ± 2,74 en el total, 4,26 ± 1,7 en D1, 7,25 ± 1,21 en D2 y 8,45 ± 1,2 en D3. El porcentaje de odontólogos con respuestas correctas fue de >79% en 7 ítems de D2 y 6 ítems de D3, mientras que en respuestas incorrectas fue de >60% en 5 ítems de D1 y 2 ítems en D2. El conocimiento total no se asoció a las variables demográficas (P≥0,067). Conclusión: Los odontólogos participantes tuvieron un conocimiento medio de la norma técnica del odontograma con mejores resultados sobre la terminología y criterios de registro de las anomalías, patologías y tratamientos dentales.

Objetivos: Estimar la asociación entre la discapacidad y la realización de actividad física en el último mes en pobladores de Chile en el año 2015. Materiales y métodos: Efectuamos un análisis transversal de los datos secundarios del Segundo Estudio Nacional de la Discapacidad (ENDISC II) de Chile. La variable dependiente fue la realización de actividad física en el último mes y la variable independiente la condición de discapacidad medida según el ENDISC II. Se integraron posibles variables de confusión. Utilizamos modelos crudos y ajustados de regresión logística ordinal y calculamos odds ratio (OR) con sus intervalos de confianza al 95% (IC 95%). Resultados: Incluimos datos de 12.236 chilenos. Aquellos con discapacidad moderada tuvieron 54% más probabilidad de realizar menos actividad física (OR = 1,54; IC 95%: 1,27 - 1,87), mientras que aquellos con discapacidad severa tuvieron 73% más probabilidad de realizar menos actividad física (OR = 1,73; IC 95%: 1,19 - 2,52), a diferencia de los no discapacitados y ajustado por múltiples variables de confusión. Conclusiones: Las personas discapacitadas en Chile tienen mayor probabilidad de realizar menos actividad física en el último mes, en comparación con sus pares sin discapacidad.

El objetivo de la presente investigación es establecer si es posible predecir las cotizaciones del mercado bursátil peruano a partir de los principales índices bursátiles de América Latina. Para ello, se analizan las cotizaciones a nivel diario de dichas bolsas durante el periodo 2006-2023. Tomando en cuenta la naturaleza de los datos de las cotizaciones, se estima un modelo de vector autorregresivo cointegrado y se aplican pruebas de exogeneidad débil y fuerte. Los resultados muestran que las bolsas de Brasil, Chile y EEUU cointegran con la Bolsa de Valores de Lima, lo que evidencia la existencia de una relación de largo plazo entre ellas. las pruebas de exogeneidad débil indican que las bolsas mencionadas ayudan a predecir el comportamiento de la Bolsa peruana un periodo hacia delante. Finalmente, las pruebas de exogeneidad fuerte indican que solo la bolsa de Brasil ayuda a predecir la trayectoria de la bolsa de Perú más de un periodo adelante.

Urban stormwater drainage alters stream flow regimes. Even small rainfall events produce higher quickflow volumes and peak flows from catchments drained using traditional stormwater management, degrading stream ecosystems. Stormwater Control Measures (SCMs) aim to mitigate such impacts. However, the cumulative effect of SCMs across a catchment on stream flow regimes has been little studied. We assessed the storm-event-quickflow volume and peak-flow response to dispersed SCMs retrofitted into existing urban catchments of 5 sites on 2 streams over 8 years, and over the same period in 3 reference and 2 control streams. Results showed that the implementation of SCMs reduced quickflow volume and peak flow at the storm-event scale. The effect was greatest for small-to-moderate storm events (2–8 mm), reflecting the finite runoff retention capacity of the implemented SCMs. This is the first catchment-scale study to demonstrate such effects for the retrofit of SCMs into urban catchments, and thus increases confidence that such investments will reduce flow-induced degradation of urban streams.
