Published: November 2024

Goat meat has a high nutritional value, since it contains up to 29% protein, as well as iron, potassium and vitamin B12. To prolong the shelf life of this food, a drying process can be applied; however, there is scarce information on the kinetics and drying parameters for this food material. The objective of this work was to characterize the thermal drying process of goat meat, through the mathematical modeling of convective drying kinetics, and its validation with experimental data obtained in a drying tunnel. The experiments were carried out with samples of loin (Longissumus dorsi) of Boer goat meat from the Mixteca region of Oaxaca (Mexico). Meat samples were subjected to air convection drying at 40, 50, 60 and 70 °C (with temperature oscillation), with air velocities of 1 and 2 m/s. Drying kinetics, air and meat temperature profiles, relative humidity and air flow velocity were recorded. Four models were analyzed: two-term, Midilli’s model, Wang and Singh’s model and a heuristic model with temperature dependence. The proposed mathematical models represented drying kinetics with an accurate fitting of experimental data, with standard errors (RMSE) in the range of 0.004–0.029. The estimated diffusion coefficients are consistent with the transport properties in biomaterials. The heuristic model was based on the solution of the effective diffusion equation considering the linearization of the temperature-dependent diffusion coefficient, showing a standard error in the range of 0.007–0.028, satisfactorily representing the temperature oscillations that allows a moisture diffusion reorganization, mainly when drastic temperature changes occur.

The milling force plays a pivotal role in CFRP milling. Modeling of the milling force is helpful to explore the changing law, optimize the processing parameters, and then reduce the appearance of defects. However, most of the existing models ignore the effect of the bottom edge. In this paper, the prediction of milling force in CFRP milling processes is taken as the research object. By analyzing the milling mechanism and considering the end milling cutter’s bottom cutting edge, the prediction model of milling force was established. Based on the experimental data and simulation data of milling force, the milling force coefficient was obtained by inverse calculation. Subsequently, the predicted cutting force was compared with the experimental cutting force, showing a maximum error of 14.5%, which is within a reasonable range, and the correctness of the model was verified. Furthermore, combined with the delamination damage and the milling force prediction model, a multi-objective optimization model of milling parameters was established, and the genetic algorithm was used to solve the model. The unidirectional carbon fiber plate with a fiber direction angle of 45° was selected as the optimization example. The minimum delamination damage was obtained under the cutting conditions of a spindle speed of 4903.1569 r/min, feed rate per tooth of 0.01 mm/z, and an axial depth of cut of 0.5 mm, and the experimental verification was carried out. The feasibility of the genetic algorithm in CFRP milling parameter optimization modeling was also verified.

Published: November 2024

Salmonella enterica serovar Infantis has emerged as a prevalent foodborne pathogen in poultry with significant global health implications. This study investigates the molecular characteristics influencing virulence in a S. Infantis rough variant collected from a poultry farm in the USA. In this study, whole genome sequencing and comparative genomics were performed on smooth and rough poultry S. Infantis isolates, while chicken embryo lethality assay was conducted to assess their virulence. Comparative genomics between isolates was analyzed using Mauve pairwise Locally Collinear Blocks to measure the genetic conservation. Embryo survival rates between the isolates were compared using the Kaplan–Meier curves. High genomic conservation was observed between the two isolates, but a frameshift mutation was detected in the Wzz(fepE) gene of the rough variant, resulting in early protein truncation. The chicken embryo lethality assay showed that the lethality rate of the smooth strain was higher than that of the rough strain (p < 0.05). This study identifies a frameshift mutation in the Wzz(fepE) gene, leading to protein truncation, which may reduce bacterial virulence by impacting O-antigen biosynthesis in the rough Salmonella Infantis variant. These findings deepen our understanding of S. Infantis pathogenesis and suggest that targeting the Wzz(fepE) gene or related pathways could be a promising strategy for developing effective vaccines and therapeutic interventions.

Published: November 2024

The Escola Universitària Formatic Barcelona (EUFB) is a prestigious university institution located in the center of Barcelona in a listed historical building at Passeig de Gràcia avenue nº 66. This article investigates the origins and characteristics of the Casa Vidua Marfà, the current headquarters of the EUFB, retracing its history and that of the families who made it a reality. A period that goes from the 18th century to the beginning of the 20th century at a time when Catalan traders known as ‘Indians’ left their mark on the architecture, gastronomy and traditions of Catalonia. The analysis of Casa Vidua Marfà constitutes an exponent of that period when Catalan merchants tended to set sail when they were young and poor and go to the Americas, especially to Cuba and Puerto Rico, in search of new job opportunities. Back from their journey abroad, if successful, ‘Indians’ continued to invest in businesses and industries throughout Catalonia and, in this particular case, contributing to the urbanization process in the center of Barcelona.

Bioarchaeological analyses of preadults provide a wealth of information about past lifeways and social structures, including aspects of personhood. However, studies of personhood and childhood in archaeological hunter-gatherer (or forager) contexts remain limited, particularly for Southeast Asia. Here, we explore aspects of personhood and the lived experiences of preadults at Con Co Ngua, an early seventh millennium BP sedentary hunter-gatherer community in northern Vietnam. We approach this analysis by way of our knowledge of skeletal representation, grave construction, body positioning, corpse manipulation (including extensive mutilation of certain individuals), and the integration of previous research into lifeways and environment.
The results of our analyses provide support for a degree of differential preadult mortuary treatment, primarily manifested through body treatment and positioning. However, interpretations of these treatments are complicated by the highly fragmented and disaggregated nature of the majority of preadult burials. We contend that the comparatively more dispersed and fragmentary nature of the preadult burials at the site is caused by intentional human action at the site, rather than differential preservation or recovery biases, and such apparent biases may actually stem from deliberate human intervention. That is, socially appropriate mortuary treatments regarding constructions of personhood, social memory, or collective identity may have led to the dispersal of preadults throughout the mortuary contexts of the site. More broadly, the mortuary evidence from Con Co Ngua supports the conclusion that all of those buried at Con Co Ngua were bestowed some degree of personhood by their community, as demonstrated through the inclusion of all in the cemetery, from foetuses to elderly adults.
Que peut apporter la sociologie pragmatique à la théorie sociale ?
Authors: Silva Corrêa Diogo 
Published: November 2024

Cet article introduit la sociologie pragmatique en s’appuyant sur trois gestes principaux, qui illustrent les changements apportés à la théorie sociale par une nouvelle « attitude » générale en sociologie. Tout d’abord, le geste métaphysique d’inversion de la sociologie classique durkheimienne, défini par le principe de « libéralité ontologique ». La sociologie pragmatique cherche à concevoir une idée du social qui n’exclut rien a priori, permettant ainsi un pluralisme ontologique radical. Deuxièmement, le geste épistémologique de délégation, visant à transférer aux acteurs eux-mêmes les critères de définition de ce qui est pertinent, juste, réel, authentique, etc. Contrairement à la rupture épistémologique prônée par Bourdieu, Passeron et Chamboredon, cette approche valorise la restitution de l’univers d’expérience des acteurs, y compris le pouvoir d’agir des entités non humaines. Enfin, le troisième geste, méthodologique, se concentre sur la sélection et le cadrage de situations d’indétermination, de moments critiques et de tensions vécues par les acteurs enquêtés. Il repose sur la mise en évidence de moments critiques lors desquels les acteurs explicitent ce qui est fondamental et pertinent pour eux. L’article soutient que ces trois gestes permettent de dépasser les postulats du « nouveau mouvement théorique » des années 1980, en proposant une sociologie mieux adaptée aux défis contemporains. En conclusion, il souligne que la sociologie pragmatique, à travers ses gestes et son attitude générale, ouvre de nouvelles perspectives pour la théorie sociale contemporaine, en intégrant des entités inattendues et en prenant au sérieux l’expérience des acteurs.
Assessment of knowledge on ultrasound physical principles and its application for image acquisition and optimization among emergency medicine trainees in Sri Lanka
Authors: Goonewardene T. , Baker K. , Lanerolle I. 
Published: November 2024

Introduction: The objective of the study was to assess the knowledge on physical principles of ultrasound and its application for image acquisition and optimisation among emergency medicine trainees in Sri Lanka.Methods: A self-administered questionnaire consisting of 5 multiple choice questions and 10 single best response questions on ultrasound physical principles and their application in image acquisition and optimisation was distributed among 62 Pre-MD emergency medicine trainees. Knowledge scores were analysed with regards to prior experience and training in Point of Care Ultrasound (PoCUS).Results: Fifty out of 65 trainees participated in the study giving a response rate of 76.9%. All registrars used PoCUS in their day-to-day practice and utilized one or more applications. The predominantly utilized application was trauma scans (n=47, 94%), followed by cardiac (n=44, 88%) and procedural guidance (n=44, 88%). The majority of the registrars (n=33, 66%) obtained a score above 50% for physics, whereas for image acquisition and optimisation, a score above 50% was obtained by 21 registrars (42%). There was no association between knowledge and completion of a PoCUS course (physical principles p=0.937, image acquisition and optimisation p=0.471) or experience in PoCUS (physical principles p=0.253, image acquisition and optimisation p = 0.648). Conclusion and recommendations: In general, results of this study do not bode well on ongoing practice of PoCUS in Sri Lanka and indicates that the current PoCUS training is in urgent need of change and revision, with emphasis on the practical application.

Introduction: Cholecystectomy, the surgical removal of the gallbladder, is common for gallstone disease. Laparoscopic cholecystectomy (LC) is favoured for its benefits over open cholecystectomy (OC). This study compares incidents and complications between the two approaches at the Surgical Professorial Unit, Teaching Hospital Karapitiya.Methods: A comparative cross-sectional study evaluated incidents and complications in LC versus OC patients from 2015 to 2023. Altogether 302 patients were sampled, meeting specific criteria, with data collected retrospectively and analysed statistically.Results: Of the 302 patients, 70.5% (n=213) had LC and 29.5% (n=89) had OC. Haemorrhage was common in OC (3.6% vs. 2.6%), while gallbladder perforation occurred more in LC (7.3% vs. 0.7%). Challenges in identifying Calot’s triangle were more frequent in LC (4.3% vs. 0.3%). Postoperatively, LC patients had shorter hospital stays (1.32 vs. 3.52 median days). Cardiac complications were common, while surgical site infections were more prevalent in OC. (2.3% vs 0.9%). Presence of comorbidities like diabetes (p=0.04) and ischaemic heart disease (p=0.037) correlated with postoperative complications significantly. Mortality rates were higher in OC (2.2% vs. 0.4%). Conversion to OC from LC was zero.Conclusions: LC is preferred method for cholecystitis due to its advantages over OC, including shorter hospital stays, and fewer complications. Higher efficacy of LC in managing comorbidities and its safety, with no conversions to OC, supports its recommendation as the treatment of choice for cholecystitis patients, particularly those with underlying health conditions.
Stripping the mangongkal holi and confirming the Holy Spirit
Authors: Gultom Rogate A.T. , Marbun Rencan C. 
Published: November 2024

The mangongkal holi tradition in Batak is a heritage from ancestors that has been the subject of prolonged theological debate. As a local phenomenon, the tradition needs to be explored with an appropriate approach to interpret it accurately. This study asserts that the ‘kernel’ and ‘husk’ approach has the potential to contribute constructively to the relationship between the church and culture in Batak, particularly regarding the mangongkal holi tradition. The research employs a qualitative-descriptive analysis approach, using books, journal articles and other references as the basis for argumentation. In conclusion, there is alignment between the expectations of culture and the church regarding mangongkal holi. The pursued values such as gratitude, honouring parents and others are elements that are consistent in both cultural appreciation and Christian faith.Contribution: This article provides insight into contextual theology, where global pneumatology and local culture could be paired in the sense that the Holy Spirit could be understood by the community within their local tradition without degrading the values of church doctrine. Rather, it enriches the culture and confirms church identity.
