De 'joglar' a 'ministrer': la introducció d'una nova designació d'ofici a la cort d'Aragó
Authors: Fernàndez-Clot Anna
Published: November 2024

L'article analitza el canvi de designació professional que es produeix a la segona meitat del segle XIV per identificar els músics documentats a la cort d'Aragó. A partir d'un examen exhaustiu de la documentació produïda al llarg del regnat de Pere el Cerimoniós (1336-87), s'estudia la terminologia que identifica els professionals de l'entreteniment i la música en els registres comptables i altres documents de cancelleria. Això permet localitzar amb precisió els artistes, els contextos i els períodes en què es comença a introduir el terme ministrer en la documentació corresponent a diferents cases (rei, reines i infants), i permet identificar a partir de quin moment el terme es generalitza a la cort d'Aragó per designar els músics. L'estudi apunta la possible relació entre la introducció d'aquest canvi de designació i la difusió de nous estils musicals provinents de França i el nord d'Europa a la Corona d'Aragó.

Authors: Mompó Jacob
Published: November 2024

El Sermó de la Immaculada Concepció de Felip de Malla s’ha conservat en un testimoni manuscrit, de la primera meitat del segle xv, i un altre imprés, de 1488. En aquest treball, a través de l’estudi ecdòtic de les variants, caracteritzem la variació que es produeix en l’imprés i identifiquem les intervencions editorials originades amb un incipient objectiu de regularitzar l’ortografia, fixar un model lingüístic i adaptar-se als lectors potencials. Referenciem igualment les lectures incorrectes, tant del copista del manuscrit com de l’incunable, i analitzem la manipulació editorial en el procés de selecció a l’hora d'eliminar fragments del text per encabir-lo en l’espai disponible del volum imprés
La irrupción de Juan de Mena en la imprenta incunable: la editio princeps del 'Laberinto de Fortuna' (85*ML)
Authors: Rodado Ruiz Ana María
Published: November 2024

El objetivo de este trabajo es el análisis de la primera edición incunable del Laberinto de Fortuna de Juan de Mena. A partir del estudio bibliográfico material del único ejemplar que se conserva, se profundiza en el análisis de las circunstancias editoriales y socioliterarias que determinaron la publicación. Aunque el impreso carece de indicaciones tipobliográficas, es altamente probable que pertenezca a la primera imprenta que trabajó en Salamanca entre 1481 y 1488. Este valioso incunable es una muestra tempranísima del interés de impresores y lectores por la obra maestra de Mena, casi tres décadas después de la muerte del poeta.
El pliego poético incunable ¿de Luis de Salazar?: materialidad, tipografía y contenidos
Authors: Martos Josep Lluís
Published: November 2024

El pliego poético que Brian Dutton identificó como 87*LS se ha considerado hasta hoy como impreso en Murcia por Lope de la Roca en 1487 o hacia 1487. De la contextualización histórica y socioliteraria del impreso, así como de su estudio material, se confirmarían los dos primeros datos, pero se sugiere una datación posterior, ya en la primera mitad de la década siguiente. En este trabajo se sostiene la existencia de un pliego perdido original del que este conservado es una edición ampliada, con la adicion de un poema y dos folios. A partir del estudio del título del impreso y de los rasgos de composición de los poemas, se defiende que Luis de Salazar solo fue autor de la última obra. Y, finalmente, se establece la estructura interna del pliego poético, delimitando y discriminando los cinco poemas contenidos en él, considerados tradicionalmente como una única composición.

Selective laser melting (SLM) has potential to prepare complex shaped amorphous alloy parts, however, the almost inevitable crystallization makes it very difficult to obtain excellent performance parts. Most of previous studies focus on improving properties by optimizing parameters such as laser power, scanning speed, and scanning strategy. As is well known, the substrate is an important component in SLM devices, which directly supports and contacts the initial powder and melting pool, affecting the absorption and transfer of heat, the formation and cooling of the melting pool, and therefore exerts a significant influence on the quality and microstructure of printed parts. However, there is relatively little research on its influence. It is important and necessary to understand the influence of substrate temperature on crystallization behavior of Fe-based amorphous alloy during SLM process. Molecular dynamics (MD) simulations can provide direct evidence for the evolution of clusters and band pairs, which can help clarify the crystallization mechanism and alleviate the crystallization. In this work, the influence of substrate temperature on the crystallization and evolution of atomic clusters in Fe50Cu25Ni25 amorphous alloy during SLM is investigated on an atomic scale, using MD simulation under different substrate temperatures (300–900 K), laser power values (500–800 eV/ps), and scanning speeds (0.1–1.0 nm/ps). The research results show that when the substrate temperature is lower than 750 K, the content of characteristic bond pair 1421 and the corresponding \begin{document}$ \left\langle{0,{\mathrm{ }}4,{\mathrm{ }}4,{\mathrm{ }}6}\right\rangle $\end{document} cluster increase with the substrate temperature rising, thereby increasing face-centered cubic bond pair and cluster and promoting the crystallization. When the substrate temperature rises to a value close to the glass transition temperature, the evolution of bond pairs and clusters becomes complex, which is influenced by the collaborative and competitive effects, such as the ability to form glass, melting and cooling rate. This work reveals the evolution of atomic clusters and band pairs in the SLM process of Fe-based amorphous alloys, and the initiation of crystal phases at different substrate temperatures, providing new ideas for understanding and regulating crystallization.

Sodium niobate-based dielectric energy storage materials, as key components in capacitors, have the advantages such as low relative density, lead-free, low cost, and excellent energy storage density, and can meet the important requirements of electronic components for miniaturization, harmlessness, integration and light weight. Therefore, they have received extensive attention from the scientific community in recent years. In this work, by introducing both Bi(Mg0.5Sn0.5)O3 and (Bi0.5Na0.5)0.7Sr0.3TiO3 components into NaNbO3 ceramics, a conventional solid-phase sintering method is used to prepare (1–x)[0.93NaNbO3-0.07Bi(Mg0.5Sn0.5)O3]-x(Bi0.5Na0.5)0.7Sr0.3TiO3 (Abbreviated as (1–x)(NN-BMS)-xBNST, 0 ≤ x ≤ 0.3) relaxation ferroelectric ceramics, and the ceramics are characterized by using X-ray diffraction, scanning electron microscopy, UV spectroscopy and Raman spectroscopy so as to study the effects of (Bi0.5Na0.5)0.7Sr0.3TiO3 doping on the physical phase composition, microstructure, and electrical properties of NaNbO3 ceramics, such as dielectric and energy storage. The (1–x)(NN-BMS)-xBNST ceramics exhibit a single perovskite structure, with cell volume a first increasing and then decreasing. The coexistence of Pbma and Pnma phases (1–x)(NN-BMS)-xBNST ceramics exhibits a dense microstructure and clear grain boundaries at an optimal sintering temperature. The average grain size first increases to 4.73 μm, then decreases to 2.17 μm, and finally increases to 3.06 μm. A smaller grain size and a larger bandgap width are beneficial for improving the breakdown strength. The 0.75(NN-BMS)-0.25BNST ceramic shows the excellent dielectric temperature stability (25–160 ℃, Δε/ε25 ℃ ≤ ±15%) and dielectric frequency stability, which can meet the EIAZ8U standard and hence work in a special environment (high temperature and high frequency). Meanwhile, 0.75(NN-BMS)-0.25BNST ceramic exhibits excellent energy storage performance at high field strength (390 kV/cm): recoverable energy density Wrec = 2.73 J/cm3, energy storage efficiency η = 82.6%, and high temperature stability in a temperature range of 20–100 ℃. The research results indicate that 0.75(NN-BMS)-0.25BNST ceramics have broad prospects of applications in lead-free dielectric energy storage capacitors.

Sensory dorsal root ganglion (DRG) neurons have a unique pseudo-unipolar morphology in which a stem axon bifurcates into a peripheral and a central axon, with different regenerative abilities. Whereas peripheral DRG axons regenerate, central axons are unable to regrow. Central axon regeneration can however be elicited by a prior conditioning lesion to the peripheral axon. How DRG axon asymmetry is established, remains unknown. Here we developed an
in vitro
system replicating DRG pseudo-unipolarization and asymmetric axon regeneration. Using this model, we observed that from early development, central DRG axons have a higher density of growing microtubules. This asymmetry was also present
in vivo
and was abolished by a conditioning lesion that decreased microtubule polymerization of central DRG axons. An axon-specific microtubule-associated protein (MAP) signature, including the severases spastin and katanin and the microtubule regulators CRMP5 and tau, was found and shown to adapt upon conditioning lesion. Supporting its significance, interfering with the DRG MAP signature either
in vitro
or
in vivo
, readily abolished central-peripheral asymmetries in microtubule dynamics and regenerative ability. In summary, our data unveil that axon-specific microtubule regulation drives asymmetric regeneration of sensory neuron axons.

Background:

Alcohol use disorder (AUD) is a global health problem with limited therapeutic options. The biochemical mechanisms that lead to this disorder are not yet fully understood, and in this respect, metabolomics represents a promising approach to decipher metabolic events related to AUD. The plasma metabolome contains a plethora of bioactive molecules that reflects the functional changes in host metabolism but also the impact of the gut microbiome and nutritional habits.

Methods:

In this study, we investigated the impact of severe AUD (sAUD), and of a 3-week period of alcohol abstinence, on the blood metabolome (non-targeted LC-MS metabolomics analysis) in 96 sAUD patients hospitalized for alcohol withdrawal.

Results:

We found that the plasma levels of different lipids ((lyso)phosphatidylcholines, long-chain fatty acids), short-chain fatty acids (i.e. 3-hydroxyvaleric acid) and bile acids were altered in sAUD patients. In addition, several microbial metabolites, including indole-3-propionic acid, p-cresol sulfate, hippuric acid, pyrocatechol sulfate, and metabolites belonging to xanthine class (paraxanthine, theobromine and theophylline) were sensitive to alcohol exposure and alcohol withdrawal. 3-Hydroxyvaleric acid, caffeine metabolites (theobromine, paraxanthine, and theophylline) and microbial metabolites (hippuric acid and pyrocatechol sulfate) were correlated with anxiety, depression and alcohol craving. Metabolomics analysis in postmortem samples of frontal cortex and cerebrospinal fluid of those consuming a high level of alcohol revealed that those metabolites can be found also in brain tissue.

Conclusions:

Our data allow the identification of neuroactive metabolites, from interactions between food components and microbiota, which may represent new targets arising in the management of neuropsychiatric diseases such as sAUD.

Funding:

Gut2Behave project was initiated from ERA-NET NEURON network (Joint Transnational Call 2019) and was financed by Academy of Finland, French National Research Agency (ANR-19-NEUR-0003-03) and the Fonds de la Recherche Scientifique (FRS-FNRS; PINT-MULTI R.8013.19, Belgium).

Phantom perceptions like tinnitus occur without any identifiable environmental or bodily source. The mechanisms and key drivers behind tinnitus are poorly understood. The dominant framework, suggesting that tinnitus results from neural hyperactivity in the auditory pathway following hearing damage, has been difficult to investigate in humans and has reached explanatory limits. As a result, researchers have tried to explain perceptual and potential neural aberrations in tinnitus within a more parsimonious predictive-coding framework. In two independent magnetoencephalography (MEG) studies, participants passively listened to sequences of pure tones with varying levels of regularity (i.e. predictability) ranging from random to ordered. Aside from being a replication of the first study, the pre-registered second study, including 80 participants, ensured rigorous matching of hearing status, as well as age, sex, and hearing loss, between individuals with and without tinnitus. Despite some changes in the details of the paradigm, both studies equivalently reveal a group difference in neural representation, based on multivariate pattern analysis, of upcoming stimuli before their onset. These data strongly suggest that individuals with tinnitus engage anticipatory auditory predictions differently to controls. While the observation of different predictive processes is robust and replicable, the precise neurocognitive mechanism underlying it calls for further, ideally longitudinal, studies to establish its role as a potential contributor to, and/or consequence of, tinnitus.
Stereotypes in linguistic innovation
Authors: Escalona Torres Juan , DiBartolomeo Megan
Published: November 2024

The discourse marker “en plan,” akin to English “like,” has gained attention due to its rapid spread across Spain. Using explicit and implicit attitude surveys, we examine perceptions of quotative marker “en plan” by Spaniards. Our findings show that “en plan” is mainly associated with younger age groups and casual speech, leading to mixed social attitudes. While some view it as a marker of youth speech and sociability, others see it as indicative of a lack of social refinement or education. The study highlights generational divides, with older speakers often stigmatizing its use, while younger speakers show neutral and positive attitudes. These attitudes reflect broader societal views on language, age, and identity. By focusing on the social perceptions and stereotypes associated with “en plan,” this research underscores the complex relationship between language and social identity, offering insights into how linguistic forms represent particular social groups and influence interactions within the speech community.
Determined Proper Nouns in Rioplatense Spanish express interpersonal proximity
Authors: Oggiani Carolina , Aguilar Guevara Ana
Published: November 2024

Following the referentialist view on proper nouns, based on  Kripke (1980),  they are expressions of type ,  pointing out to entities  directly, without providing a description of those  entities (cf. Kaplan 1989, Soames 2002, Jeshion 2015, Saab & Lo Guercio 2018).  Proper nouns preceded by the definite article in Rioplatense Spanish challenge this approach because the definite article, of type < >,  is neither  combining with an  NP of type  , nor contributing with its propositional meaning, namely, definiteness. In this squib, we tackle this challenge by proposing that the article preceding a proper noun in Rioplatense Spanish is an expletive of type   (Longobardi 1994; Saab 2021; Tsiakmakis & Espinal 2022), which  brings along the expressive meaning  of interpersonal proximity by activating the interactional structure above the DP (a là Wiltschko 2021).
Myositis Ossificans of the Thighs Due to Repeated Assault: A Case Report
Authors: Heo Jin-Haeng , Kwon Jeong-hwa , Cha Jang Gyu , Jang Seon Jung
Published: November 2024

Myositis ossificans (MO) is defined as a lesion where abnormal ossification forms in soft tissues, such as muscle, fascia, and ligament, usually as a result of trauma. It commonly appears in areas such as the thigh, hip, and elbow, though it can affect any part of the body. In the forensic field, MO resulting from trauma is reported to be valuable evidence of repeated physical abuse. This case report describes a deceased adult male with an intellectual disability, whose cause of death was multiple injuries from assault. Postmortem computed tomography (PMCT) and autopsy findings revealed MO of both thighs associated with repeated physical abuse. This case also showed typical findings of MO on PMCT imaging, characterized by well-defined, high-density lesions within the quadriceps. Adults with intellectual disabilities are at high risk of abuse and assault. Therefore, autopsy findings of MO can serve as important evidence in forensic practice, considering the possibility of repeated abuse.

Published: November 2024

A thriving agricultural system is the cornerstone of an expanding economy of agricultural countries. Farmers’ crop productivity is significantly reduced when they choose the crop without considering environmental factors and soil characteristics. Crop prediction enables farmers to select crops that maximize crop yield and earnings. Accurate crop prediction is mainly concerned with agricultural research, which plays a major role in selecting accurate crops based on environmental factors and soil characteristics. Recently, recommender systems (RS) have gained much attention and are being utilized in various fields such as e-commerce, music, health, text, movies etc. Machine learning techniques can help predict the crop accurately. We proposed an innovative artificial neural network (ANN) based crop prediction system (CPS) to address the farmer’s issue. The parameters considered during sensor-based soil data collection for this study are nitrogen, phosphorus, potassium, temperature, humidity, pH, rainfall, electrical conductivity, and soil texture. Python programming language is used to design and validate the proposed system. The accuracy and reliability of the proposed CPS are assessed by using accuracy, precision, recall, and F1-score. We also optimized the proposed CPS by performing a hyperparameter Optimization analysis of applied learning methods. The proposed CPS model accuracy for both real-time collected and state-of-the-art datasets is 99%. The experimental results show that our proposed solution assists farmers in selecting the accurate crop and producing at their best, increasing their profit.
A novel IoT-device management platform for on-the-fly generation of user interface via manifest-file addressing heterogeneity
Authors: Gupta Nayancy , Banda Gourinath , Bommakanti Krishna Chaitanya , Kothapalli Venkata Srinivas
Published: November 2024

The Internet of Things (IoT) is becoming indispensable across various application domains. In the domain of the consumer IoT, many original device manufacturers are coming up with a wide variety of IoT-based products and services catering with a range of applications such as personal-fitness training devices, healthcare devices, to smart-home things, etc. There is an accompanying smartphone application, called the IoT control app (ICA) through which such IoT devices are controlled. As of now, a user shall install a separate ICA app for each and every IoT device they own. This is because of the diverse heterogeneity inherent in the IoT domain. The installation of multiple ICAs leads to: memory congestion, steeper battery discharging and increased vulnerability—in smartphones. The diversity in IoT devices can be systematically abstracted away with text written in a manifest file. Based on this manifest file, a user-interface for the IoT-device gets generated on the fly by the ICA. In this article, we propose a manifest-based IoT-device platform including an application-layer protocol, which makes it possible for a single ICA App to control any compliant IoT-device after appropriate authentication. We developed a manifest-grammar for specifying error-free manifest files for different IoT-devices towards a seamless integration between ICA and IoT-devices.
Advancing multi-categorization and segmentation in brain tumors using novel efficient deep learning approaches
Authors: RajamohanReddy Nadenlla , Muneeswari G.
Published: November 2024

Background

A brain tumor is the development of abnormal brain cells, some of which may progress to cancer. Early identification of illnesses and development of treatment plans improve patients’ quality of life and life expectancy. Brain tumors are most commonly detected by magnetic resonance imaging (MRI) scans. The range of tumor sizes, shapes, and locations in the brain makes the existing approaches inadequate for accurate classification. Furthermore, using the current model takes a lot of time and yields results that are not as accurate. The primary goal of the suggested approach is to categorize whether a brain tumor is present, identify its type and divide the affected area into segments.

Methods

Therefore, this research introduced a novel efficient DL-based extension residual structure and adaptive channel attention mechanism (ERSACA-Net) to classify the brain tumor types as pituitary, glioma, meningioma and no tumor. Extracting features in brain tumor analysis helps in accurately characterizing tumor properties, which aids in precise diagnosis, treatment planning, and monitoring of disease progression. For this purpose, we utilized Enhanced Res2Net to extract the essential features. Using the Binary Chaotic Transient Search Optimization (BCTSO) Algorithm, the most pertinent features in terms of shape, texture, and colour are chosen to minimize complexity.

Results

Finally, a novel LWIFCM_CSA approach is introduced, which is the ensemble of Local-information weighted intuitionistic Fuzzy C-means clustering algorithm (LWIFCM) and Chameleon Swarm Algorithm (CSA). Conditional Tabular Generative Adversarial Network (CTGAN) is used to tackle class imbalance problems. While differentiating from existing approaches, the proposed approach gains a greater solution. This stable improvement in accuracy highlights the suggested classifier’s strong performance and raises the possibility of more precise and trustworthy brain tumor classification. In addition, our method’s processing time, which averaged 0.11 s, was significantly faster than that of previous approaches.
DTS-AdapSTNet: an adaptive spatiotemporal neural networks for traffic prediction with multi-graph fusion
Authors: Shi Wenlong , Zhang Jing , Zhong Xiangxuan , Chen Xiaoping , Ye Xiucai
Published: November 2024

Traffic prediction is of vital importance in intelligent transportation systems. It enables efficient route planning, congestion avoidance, and reduction of travel time, etc. However, accurate road traffic prediction is challenging due to the complex spatio-temporal dependencies within the traffic network. Establishing and learning spatial dependencies are pivotal for accurate traffic prediction. Unfortunately, many existing methods for capturing spatial dependencies consider only single relationships, disregarding potential temporal and spatial correlations within the traffic network. Moreover, the end-to-end training methods often lack control over the training direction during graph learning. Additionally, existing traffic forecasting methods often fail to integrate multiple traffic data sources effectively, which affects prediction accuracy adversely. In order to capture the spatiotemporal dependencies of the traffic network accurately, a novel traffic prediction framework, Adaptive Spatio-Temporal Graph Neural Network based on Multi-graph Fusion (DTS-AdapSTNet), is proposed. Firstly, in order to better extract the hidden spatial dependencies, a method for fusing multiple factors is designed, which includes the distance relationship, transfer relationship and same-road segment relationship of traffic data. Secondly, an adaptive learning method is proposed, which can control the learning direction of parameters better by the adaptive matrix generation module and traffic prediction module. Thirdly, an improved loss function is designed for training processes and a multi-matrix fusion module is designed to perform weighted fusion of the learned matrices, updating the spatial adjacency matrix continuously, which fuses as much traffic information as possible for more accurate traffic prediction. Finally, experimental results using two large real-world datasets demonstrate that the DTS-AdapSTNet model outperforms other baseline models in terms of mean absolute error (MAE), root mean square error (RMSE), and mean absolute percentage error (MAPE) when forecasting traffic speed one hour ahead. On average, it achieves reductions of 12.4%, 9.8% and 16.1%, respectively. Moreover, the ablation study validates the effectiveness of the individual modules of DTS-AdapSTNet.
Image based visual servoing with kinematic singularity avoidance for mobile manipulator
Authors: Hernandez-Barragan Jesus , Villaseñor Carlos , Lopez-Franco Carlos , Arana-Daniel Nancy , Gomez-Avila Javier
Published: November 2024

This article presents an implementation of visual servoing (VS) for a redundant mobile manipulator in an eye-in-hand configuration. We used the image based visual servoing (IBVS) scheme, which means the pose control of the robot is based on the error features in the image of a camera. Conventional eye-in-hand VS requires the inversion of a Jacobian matrix, which can become rank deficient, provoking kinematic singularities. In this work, the inversion of the Jacobian matrix is solved using damped least squares (DLS) to reduce singularities and smooth out discontinuities. In addition, a task prioritization scheme is proposed where a primary task performs the eye-in-hand IBVS task, and a secondary task maximizes a manipulability measure to avoid singularities. Finally, a gravity compensation term is also considered and defined on the basis of the image space error. The effectiveness of the proposed algorithm is demonstrated through both simulation and experimental results considering the Kuka YouBot.

The pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) is a serious insect pest of cotton crop. The studies to evaluate the impact of abiotic factors on cotton pests’ biology are limited. The current study was undertaken to determine the impact of abiotic factors (temperature, humidity, photoperiod) and an insecticide (lambda-cyhalothrin) on the biological aspects of P. gossypiella. The results revealed that all the treatments showed a significant impact on different life parameters of P. gossypiella. The temperature exposure at 27 °C revealed a total life span of about 33 days. Maximum mortality for larvae (51.11%), pupae (59.04%) and adults (61.92%) were recorded at 33 °C exposure. Both low and high humidity levels caused negative impacts on life parameters of P. gossypiella. The life span was completed in about 30 days at 60% relative humidity (RH). Maximum mortality for larvae (75.00%) and pupae (49.59%) were recorded at 80% RH level exposure, while adult mortality was maximum (63.09%) at 40% RH level followed by 80% RH level (55.52%). The P. gossypiella exhibited a life span of about 32 days at 14:10 light-dark period. The larval mortality was maximum (14.83%) at 12:12 light-dark period while pupal (47.36%) and adult (48.84%) mortality was maximum at 16:08 light-dark period. Lambdacyhalothrin (LC) showed dose dependent negative impacts on biological aspects of P. gossypiella. The P. gossypiella exhibited a life span of about 26 days at 0.5 ppm LC concentration. The P. gossypiella exposure to highest concentration (LC) revealed maximum mortality of larval (80.22%), pupal (64.63%) and adult (70.74%) stages. Conclusively, the best suited abiotic factor ranges were 27 °C (temperature), 60% (RH) and 14:10 (light-dark) which can be used for successful rearing and bioassay activities of P. gossypiella.

Published: November 2024

The aim of this study was to examine the relationship between the classroom management communication abilities and social interaction skills of language teachers in public secondary schools in Arakan North District, Division of Cotabato. The study employed a descriptive correlation method. The respondents were language teachers from public elementary schools, who assessed their own communication and social interaction skills through a questionnaire administered by the researcher. Universal sampling was used to select the participants. The data collected were categorized, analyzed, and interpreted using statistical tools, including the mean and Pearson’s r correlation. The findings revealed that the level of classroom management communication abilities among the teachers is high, and these abilities are oftentimes demonstrated in their teaching practices. Similarly, social interaction skills were also rated high and oftentimes exhibited by the teachers. Additionally, a significant relationship was found between classroom management communication abilities and social interaction skills, leading to the rejection of the null hypothesis. Based on these results, it is recommended that teachers continue to enhance their communication and social interaction skills to foster a better work environment for themselves and their colleagues. The study’s findings may serve as a source of motivation for teachers to remain engaged in their professional duties and maintain dignity and effectiveness in their roles. Moreover, the results can guide teachers in adapting to the changing dynamics of the school environment. Finally, this study provides a foundation for future research, offering insights into how these variables can be further explored in broader contexts.

Published: November 2024

The field data collection was conducted before the war (before October 2020) in Tigray Regional State, Ethiopia. The objective of the study was to determine the relationships between the linear body traits (LBTs) and body weight of the indigenous sheep, and to develop regression equations for predicting live body weights of each population. Begait (173), Rutanna (151) and Arado (164) sheep of sample animals were randomly involved in the field data collection. Dentition was used to determine the age of the animals and were from one permanent pair of incisor up to four pairs of permanent incisors. The data were analyzed by Statistical Package for Social Sciences software. The indigenous sheep populations were kept under low input extensive production system. The overall mean direct field weighed live body weights of the Begait, Rutanna and Arado sheep populations were 40.4±0.49 Kg, 48.3±0.94 Kg and 28.3±0.29 Kg, respectively. The correlations (P<0.01) between LBTs and direct field weighed live body weights of the indigenous sheep revealed that the LBTs could be used as indirect selection traits and could also be used to predict the live body weights of the indigenous sheep in areas where weighing scale is not available by using different regression equations. Chest depth (ChD = 0.817) and chest girth (ChG = 0.880) in Begait, ChD (0.874) and ChG (0.913) in Rutanna, and ChD (0.705) and ChG (0.788) in Arado sheep were among the highly significantly (P<0.01) correlated LBTs with the body weights of the indigenous sheep populations. Except in male Rutanna, chest girth or chest circumference could be solely used to predict the live body weights of the indigenous sheep breeds. This characterization work revealed that the Rutanna sheep (a transboundary breed) could be primarily used for mutton production due to their large live body weights. Genetic characterization of the indigenous sheep populations should be conducted for the identification of economically important candidate genes of the populations.

Modeling means finding a mathematical relationship between coordinates. focused on the kinetics of herring fish. Herring fish, known in the Congo vernacular as “makouala”, is available in large quantities in the country. Its consumption and exploitation constitute an important source of nutrients and revenue. The aim of this study is to investigate the behavior of herring (Clupea harengus) flesh during continuous convective oven drying at three different temperatures (50, 60 and 70°C).  The expriment was carried out by oven-drying kinetics at the three (3) temperatures mentioned above. Five (5) semi-theoretical mathematical models were used to describe the drying kinetics, with the coefficient of determination (R2), the statistical parameters reduced ki-square (χ2) and the root-mean-square error (RMSE) being used to assess the quality of the smoothing of the curves for mass loss, dry base content and drying speed as a function of time. Effective diffusivity and activation energy were also evaluated and discussed in this work. The results obtained provided plots of the evolution of mass, dry base content and drying rate as a function of time. Among the models examined, the “Midilli et al. [1]” model appeared to best describe the drying behavior of herring fish under the experimental conditions studied, with coefficient of determination (R2) values of 0.99808, 0.99663 and 0.99811 at 50, 60 and 70°C respectively. Effective diffusivity (Deff) values calculated in m2/s were for the same temperature order 2.52993 x 10-5 m2/s ; 2.45657 x 10-6 and 4.21370 x 10-6 for an activation energy (Ea) equal to 83.80 kj/mol.

A field experiment carried out during the Zaid 2024 at the Research Farm, School of Agriculture, OM Sterling Global University, Hisar (Haryana) India, to study the effects of different organic nutrient regimes combined with biofertilizer applications on nodule formation, yield, and nutritional quality of mung bean crops. Seven treatments involving organic manures and biofertilizers were tested in a randomized block design with three replications. The results showed a significantly higher number of root nodules per plant (11.33, 22.33, 19.72, and 13.44) and dry weight of nodules per plant (11.47, 22.86, 19.79, and 13.30 mg) at 30, 45, 60 DAS and at harvest, respectively. Yield results included seed yield (1,197 kg/ha), stover yield (2,342 kg/ha), biological yield (3,539 kg/ha), and harvest index (33.84%). Quality measures such as protein content (20.08%) and protein yield (240.32 kg/ha) were highest in the treatment with Jeevamrutha at 3000 l/ha applied in three splits (at sowing, 30 DAS, and 45 DAS) combined with Rhizobium and PSB (T7), while the lowest results for these parameters were observed in the control treatment.

Objetivo: Estimar a frequência de preenchimento do quesito raça/cor/etnia e associação entre a raça/cor negra e óbitos por COVID-19, no município de Camaçari, na Bahia, entre anos de 2020 e 2021.  Método: Trata-se de um estudo observacional, transversal, através do levantamento de informações do Departamento de Informática do SUS (OpenDATASUS). Investigou-se a distribuição de casos de COVID-19 por raça/cor/etnia e a distribuição, para as variáveis: faixa etária, sexo e existência de comorbidades. A regressão logística, por subgrupos, foi utilizada para análise de dados e foram estimadas Odds Ratio, seus respectivos intervalos de confiança a 95% e valor de p, obtido por meio do teste qui-quadrado (χ2). Resultados: Os achados mostraram que, para o ano de 2020, o quesito raça/cor/etnia não foi preenchido em 19,7% dos casos confirmados de COVID-19, enquanto no ano seguinte, foi 28,54%. Para os anos de 2020 e 2021, foram mais acometidos pelo agravo, indivíduos negros com idade inferior a 60 anos, com maior proporção do sexo masculino e maior ocorrência de pelo menos um fator de risco para COVID-19, quando comparadas aos indivíduos não negros. Negros sem comorbidades tiveram 16% mais chances de óbito (OR: 1,16; IC 95% 1,02 – 1,31), quando comparados aos não negros, esses achados foram estatisticamente significantes, ao se ajustar para as variáveis idade e sexo (p <0,018). Conclusão: O quesito raça/cor/etnia, ainda possui seu registro negligenciado. Indivíduos negros com COVID-19 que não apresentavam um fator de risco prévio para doença, tiveram maior chance de mortalidade, quando comparados a indivíduos não negros.

Introdução: A pandemia da COVID-19 afetou as relações sociais, econômicas e a organização do trabalho. Entre as consequências das medidas preventivas, estavam as alterações nas atividades laborais, medo de infecção, o isolamento, dificuldades financeiras e as incertezas sobre o futuro, o que poderia acarretar sobrecarga física e mental. Objetivo: analisar o impacto da pandemia na qualidade de vida (QV) e do sono (QS) em docentes universitários da área de saúde da UEPB. Metodologia: Trata-se de um estudo quantitativo, descritivo e analítico, de corte transversal, com recrutamento dos docentes por meio de divulgação eletrônica, respondendo a um questionário virtual, com perguntas abordando aspectos sociodemográficos, laborais, hábitos de vida, o WHOQOL-bref para avaliar a QV e o PSQI para avaliar a QS. Os dados foram analisados através do software estatístico SPSS (versão 22.0). Foi realizada correlação de Spearman entre dados investigados e os escore total e de cada domínio da WHOQOL-bref e PSQI, além da análise por meio de regressão linear múltipla (modelo Stepwise) para explicar se há influência na variância desses dados. O nível de significância adotado foi de p < 0,05. Resultados: Participaram 56 docentes, e encontrou-se valores nos escores que indicam QV mediana, QS ruim e presença de distúrbio do sono em alguns professores. Verificou-se correlações estatisticamente significativas negativas moderadas indicando que quanto melhor a qualidade de sono, maior a qualidade de vida. Conclusão: Os achados apontam alterações em diversas variáveis investigadas, inferindo-se que a pandemia causou impacto negativo para QV e QS dos docentes investigados.
