Genetic group, age at entry into confinement and at slaughter, are characteristics that have an important influence on lamb performance and carcass. The aim of this study was to evaluate the performance, carcass characteristics and non-carcass components from different genetic groups (Santa Inês and ½ Dorper x ½ Santa Inês) sheep, submitted to different feedlot entry and exit strategies. Were used 72 lambs males and castrated; 36 Santa Inês (SI) and 36 crossbred (Dorper x Santa Inês–DSI), with 6 months of average initial age. The groups were established in a completely randomized experimental design, in a 2x3x4 factorial arrangement, from the combination of genetic groups (GG), body weight at the beginning of confinement (WBC) and length of stay in confinement (LSC). The body weight classes at the beginning of confinement were: light (25 kg), intermediate (28 kg) and heavy (31 kg), for Santa Inês and crossbreeds, respectively. Slaughters were carried out every 28 days of confinement, in four LSC: 0, 28, 56 and 84 days. The GG did not influence performance, carcass and non-carcass component traits of lambs (p > 0.05). There was an effect of the WBC on the weights: final (FW), metabolic (MW), body at slaughter (BWS), empty body (EBW), hot carcass (HCY) and cold (CCW), loin, shoulder, leg musculature; loin eye area (LEA) and loin fat (p < 0.05). There was also an effect on LSC, for FW, average daily weight gain (ADG), MW, weight and yield of body components, weight of cuts and tissue ratio components of cuts (p < 0.05). In non-carcass components, effect on full and empty weight of: omasum, rumen-reticulum, small intestine; empty large intestine, liver and kidneys, paws and skin, and perirenal, pelvic and inguinal fat (p < 0.05). Interaction double effect on the tissue muscle/fat:bone ratio (MF:B) and for the full omasal component (p < 0.05). And triple interaction effect for ADG, full omasum and perirenal fat (p < 0.05). Weight at the beginning of confinement and confinement time are the characteristics that most influence performance, quantitative characteristics of carcass and non-carcass components. Regardless of the genetic group and age class, the animals reach the same weight after 84 days of confinement. Thus, the confinement of heavier lambs (31 kg) can be a profitable alternative, as they presented the highest weights for the most commercially valued cuts (shank and loin). The confinement strategy must adapt to market situations.

Objective

The present study aimed to identify the social cognitive predictors of regular dental visits and mouth self-examination behaviors among the elderly population, based on the Health Action Process Approach (HAPA) model.

Background

Regular dental visits and mouth self-examination can prevent oral and dental problems among the elders. Little information is available regarding the social cognitive predictive factors of these two behaviors.

Materials and methods

A cross-sectional study was conducted in 24 municipality centers in Tehran, Iran in 2021. The centers were selected randomly using a multi-stage cluster sampling method and 301 elderly attendants aged 60≥years participated in the study. Data collection was done using a researcher-made questionnaire including demographic characteristics and the HAPA model constructs for two target behaviors. Data were analyzed using the Smart-PLS version 3.3.9 via correlation and PLS-SEM analysis.

Results

The mean age of the participants was 65.3±5.33 years and 79.7% were female. The SEM analysis showed that Action Self-Efficacy [b (SD) = 0.595 (0.065), P< 0.001] and Risk Perception [b (SD) = 0.218 (0.070), P< 0.002] were predictors of Intention for mouth self-examination but only Action Self-Efficacy [b (SD) = 0.651 (0.043), P< 0.001] was predictor of Intention for regular dental visits. Recovery Self-Efficacy and Planning directly contributed to the prediction of Mouth Self-Examination. The relationship between Maintenance Self-Efficacy and both behaviors is mediated by Planning. Also, the mediating role of Planning between Intention and target behaviors was confirmed.

Conclusion

Action self-efficacy predicted the intention for regular dental visits and mouth self-examination behaviors. The relationship between intention and both behaviors was mediated by Planning. Emphasis on improving Action Self-Efficacy and Intention formation will enhance the effectiveness of interventions aiming at promoting the oral health of the elderly population.

Published: November 2023

Background

In recent years, various studies have been conducted to investigate the relationship between erythropoiesis-stimulating agents (ESAs) and mortality in hemodialysis patients, who showed contradictory results. Therefore, this study aimed to investigate the relationship between ESAs and mortality in hemodialysis patients.

Methods

The current study is a systematic review and meta-analysis based on observational and interventional studies published in the Web of Science, Cochrane Library, Science Direct, PubMed, Scopus, and Google Scholar databases between 1980 and the end of 2022. Jadad scale checklist and Newcastle Ottawa scale were used to evaluate the quality of articles. The study data were analyzed using Stata 15 software.

Results

In the initial search, 3933 articles were extracted, and by screening and considering the research criteria, 68 studies were finally included in the meta-analysis. According to the meta-analysis results, the risk ratio (RR) of overall mortality in hemodialysis patients receiving ESAs was equal to 1.19 (95% CI: 1.16–1.23, P ≤ 0.001). The RR of mortality in patients aged 60 years and under was equal to 1.33 (1.15–1.55, P ≤ 0.001), in the age group over 60 years was equal to 1.13 (1.10–1.16, P ≤ 0.001), in randomized clinical trial studies was equal to 1.06 (0.80–1.40, P = 0.701), in cohort studies was equal to 1.20 (1.16–1.25, P ≤ 0.001), in American countries was equal to 1.19 (1.10–1.29, P ≤ 0.001), in Asian countries was equal to 1.15 (1.10–1.19, P ≤ 0.001), and in European countries was equal to 1.18 (1.05–1.34, P = 0.007).

Conclusion

The results of the study show that receiving ESAs is associated with a 19% increase in the risk of overall mortality in hemodialysis patients.
An Unusual Case of Black Esophagus
Authors: Ziegler Patricia E. , Rosario Lora Dauris , DeMeo Mark
Published: November 2023

Patients with acute esophageal necrosis often present with hematemesis and upper gastrointestinal bleeding. Our case report describes a patient's incidental discovery of black esophagus without recent hemodynamic instability, symptoms, or evidence of blood loss anemia. As illustrated in this case, it is important to recognize these findings in patients without classic signs and symptoms to act promptly and prevent tissue ischemia or perforation. Early recognition can also help reduce the risk of long-term complications such as stricture formation. Thus, a high index of suspicion is essential for the diagnosis of acute esophageal necrosis.

Published: November 2023

The influence of the construction period of the bridge project across the reservoir on the adjacent power station includes not only the direct impact on the hydropower hub but also the impacts on the reservoir area, flood discharge, power station head, water diversion and sediment prevention, power generation operation, and other factors. In this paper, from the aspects of the power station operation, an evaluation index for the influence of the construction period of a bridge across a reservoir on the adjacent power station is developed, and an evaluation system is constructed. Based on the constructed evaluation system, the influence of the bridge construction period on the adjacent power stations is analyzed. This evaluation system provides a reference for the impact assessment of cross-reservoir bridge engineering on adjacent hydropower stations.
Investigation on the Rock-Fragmentation Process of Conical-Shaped TBM Cutterhead in Extremely Hard Rock Ground

Published: November 2023

Conical-shaped cutterhead is one type of tunnel boring machine (TBM) cutterhead which may have advantage of high rock-breaking efficiency in extremely hard rock ground. This study investigated the rock-fragmentation process of disc cutters on the conical-shaped cutterhead via a series of numerical simulations that had been verified by laboratory rock-fragmentation tests. Firstly, the rock-fragmentation numerical model of the six cutters in the 'flat-cone' contiguous part was built based on cutting mode analysis of the conical-shape cutterhead. The rock sample in the numerical model was synthesized using a grain-based discrete element method (GB-DEM) and the reliability of this approach was verified via scaled rock-fragmentation tests conducted on a self-developed linear cutting machine (LCM). Then, a series of numerical simulations were conducted to study the influence of cutterhead cone angle, cutter spacing, and cutter installation angle on the rock-fragmentation performance. The results were as follows: 1) the nature of rock fragmentation in the cone area is the rock fragmentation under side free-face condition; 2) the penetration specific energy can be reduced and thus the rock-fragmentation efficiency can be improved by appropriately increasing the conical angle, reducing the cutter spacing, and increasing the cutter installation angle; 3) for the studied granite, the optimal conical angle is 25°, the cutter spacing is suggested to be no more than 70 mm, and the cutter tilt angle is suggested to be no more than 3°. The results obtained in this paper can be used as guidance for the design of the conical-shaped cutterhead.
Enabling interdisciplinary research capacity for sustainable development: Self- evaluation of the Blue Communities project in the UK and Southeast Asia
Authors: Culhane Fiona , Cheung Victoria , Austen Melanie
Published: November 2023

Global challenges such as climate change, food security and human health and wellbeing disproportionately impact people from low-income countries. These challenges are complex and require an international and transdisciplinary approach to research, with research skills and expertise from different disciplines, sectors, and regions. In addressing this, a key goal of the research project, Blue Communities, was to create and expand mutual interdisciplinary capacity of both United Kingdom and Southeast Asian Partners. An existing questionnaire on research capacity was uniquely adapted to include interdisciplinary and international aspects and distributed for the first time as an online survey to the participants of the Blue Communities project comprising researchers across all career stages. Participants were asked about their perceptions of the research capacity and culture of their organisation, team and self and whether they believed any aspects have changed since involvement with the project. Greatest improvement was seen at the self level where results indicated a positive relationship between an individual’s current success or skill and their improvement over the course of the research project across 18 out of 22 aspects of research capacity for Southeast Asian, and 2 for UK respondents. The conflict between achieving research aims, building research capacity and making societal impact was evident. Institutional support is required to value these core aspects of interdisciplinary research.

Cass., 27 septembre 2022, R.G. n° P.22.1122.N
Authors: Desguin Noemi
Published: November 2023

Depuis près de 40 ans, la Cour de cassation a développé une jurisprudence dite « sans objet » en vertu de laquelle le recours introduit par l’étranger détenu est quasi systématiquement déclaré irrecevable en cas de nouveau titre de détention pris par l’Administration, de rapatriement ou de remise en liberté de l’étranger concerné pendant le temps de l’examen du recours. De quoi sérieusement s’arracher les cheveux en tant que praticien et de rendre extrêmement complexe toute tentative de l’étranger de faire valoir ses droits devant les juridictions d’instruction. Cette jurisprudence était devenue difficilement conciliable avec les arrêts de la Cour européenne des droits de l’homme condamnant la Belgique pour ses défaillances en matière de recours pour l’étranger détenu, le dernier en date rendu dans l’affaire Saqawat. L’arrêt ci-commenté de la Cour de cassation, opère une volte-face pour le moins inattendue. La Cour y abandonne sa ligne de jurisprudence traditionnelle et ce faisant, ouvre la brèche à la réforme tant attendue du recours en matière de détention.

Published: November 2023

In the Algerian steppe (Rogassa) overgrazing led to the reduction of the surface of the pasture land and its biodiversity. The objective of this work was to highlight the importance of the protected land in maintaining biodiversity and preserving the degraded areas. A mixed sampling for the two different sites was adopted, where fifty floristic surveys were conducted using the Braun-Blanquet method. The analysis of the real biological spectrum of the unprotected land was marked by the strong dominance of the therophytes. However, in the protected land the chamaephytes dominated all of the biological types. The analysis of the biogeographic spectra revealed the reappearance of the endemic species (+3%). The Shannon Index was very important in this matter (2.43). The Student’s t-test of the biodiversity’s index showed a highly significant difference between the two sites. The ascending hierarchical classification revealed that the protected land is subdivided into four groups dominated respectively by: Macrochloa tenacissima, Lygeum spartum, Artemisia erba-alba and Hordeum murinum. The results of the Jaccard dissimilarity index indicated a strong difference of the order of 80% between the two areas.
Edukacja emocjonalna a rozwój emocjonalny dziecka
Authors: Kubiak Hanna , Kubiak-Frątczak Aleksandra
Published: November 2023

In recent years, the need to consciously care for the emotional development of children has been increasingly recognized in the social space. The concepts of emotional intelligence (Goleman, 2007) or emotional competence (Saarni, 1988, pp. 115-82) reflect the interest in this particular sphere of development. This type of intelligence includes the ability to understand one’s own and others’ emotions, which is the source of competences related to reading emotions, being aware of and “managing” them. They are to enable the achievement of a wide range of goals: interpersonal, professional and related to selfdevelopment. Realizing this potential largely depends on the course of the emotional development process. The aim of this article is to outline the framework for the emotional development of a child, to search for ways to strengthen protective factors and to indicate methods of supporting children and adults – parents, teachers, educators, psychologists, and doctors.

Rewind, Forward, Skip: Tabs of Memory to play with the Narrative Tempo
Authors: Tholia Shipra , Singh Amar
Published: November 2023

Memory narratives, like all fictional narratives, are characterized by variation in narrative pace, resulting from a variety of staging strategies. In memory literature, the change in narrative pace is particularly evident because the representation of memory encourages a variety of narrative pacing strategies – from acceleration to deceleration. A great deal of attention is given to the representation of memory content when reviewing narratology from a memory studies perspective. There is, however, one aspect that is often overlooked, namely the way in which memories themselves determine the pace of the narrative. Memory content not only affects the narrative pace in significant ways but in most cases, the representation of memory also dictates the narrative pace by employing several memory-elicited pace strategies. As part of this paper, we propose a narratological approach that emphasizes narrative pace as the basis for analyzing the memory literature related to transgenerational memory communication. This paper examines the narrative techniques in the the construction of memory-elicited narrative pace. Furthermore, this paper discusses how memory itself takes on different roles based on varying narrative paces and how memory itself can influence narrative pace. The paper uses three memory novels as case studies: Herzklappen von Johnson & Johnson by Valerie Fritsch, Briefe nach Breslau: Meine Geschichte über drei Generation by Maya Lasker-Wallfisch, and Zurück nach Berlin: wie mein Vater mit mir in seine Vergangenheit reiste by Jonathan Lichtenstein. Each of these novels focuses on the transmission of a transgenerational memory of World War II. Using examples from these novels, this paper explains how the suturing of memory content generates the five primary rhythms of narrative movement: ellipsis, summary, stretch, pause, and scene.

Objectives

Tissue transglutaminase (tTG) IgA antibodies are a hallmark for celiac disease (CD). In CD patients on gluten free diet (GFD) these antibodies are transient. Few studies are available comparing the tTG-IgA assay characteristics for monitoring response to GFD. Since discrepant results were reported in patients on GFD after switching tTG-IgA assays, we conducted a retrospective observational study to monitor GFD response using three different tTG-IgA assays.

Methods

Diagnostic samples from 44 adults and 17 children with CD were included. Of most patients two follow-up samples after introduction of GFD were available. In all samples tTG-IgA were assessed using one fluorochrome-enzyme immuno-assay (FEIA) and two chemiluminescence immuno-assays (CLIA) and intestinal fatty acid binding protein (i-FABP) as surrogate marker for intestinal epithelial damage was measured.

Results

Using CLIA assays, normalization of antibody levels was delayed compared to FEIA (p<0.001). Of all samples taken after at least 6 months on GFD with elevated i-FABP indicating intestinal epithelial damage, 40 % had positive tTG-IgA according to the FEIA, 85 and 90 % according to the two CLIA.

Conclusions

Normalization of tTG-IgA in patients on GFD depends on the assay used. Both CLIA appear to be more sensitive in detecting suboptimal treatment response in CD-indicated by elevated i-FABP – when applying the manufacturer’s recommended cut-off for the diagnosis of CD.

Published: November 2023

Constructing a green and harmonious cyberspace in a network content ecosystem is a beautiful vision for millions of netizens. This study, by establishing a self-compiled corpus of judicial discourse from digital platform typical cases in China and using a combination of corpus-based approach and case analysis method, represents the development status of the Chinese network content ecosystem in order to develop a model for understanding and evaluating a network content ecosystem. Based on the analysis results of Chinese judicial discourse, an evaluation model, namely the People, Object, Technology, Organization, Government, Environment Framework (POTOGE), is derived after examining and evaluating four conceptual frameworks of the People, Process and Technology Framework (PPT), the Technology, Organization and Environment Framework (TOE), the Real Access/Real Impact Framework (RA/RI) and the People, Technology, Organization and Environment Framework (PTOE). To some extent, the POTOGE evaluation model presents a holistic and comprehensive perspective for understanding and evaluating a network content ecosystem and its key components, which can provide a reference for testing standards to ensure the sustainable development of current and future network content ecosystems. Meanwhile, the insights obtained from this study may help deepen our understanding of the judicial discourse and its thinking in the network content ecosystem. The analysis results of typical cases on digital platform can provide a reference for the formulation of future relevant laws and regulations and improve the legal protection and prevention awareness of society.
Negotiation of justice: the discursive construction of attitudinal positioning in bilingual legal judgments of HKSAR v KWAN WAN KI
Authors: Yu Wei
Published: November 2023

In appeal cases, judges from different levels of courts may have varying perspectives on the same set of facts, leading to different sentencing decisions. This study focuses on a specific traffic incident case in Hong Kong. In this case, a trial judge and a collegial panel at the High Court hold divergent opinions regarding the same set of facts, expressed through two different narrations and varying degrees of leniency in their rulings. By applying the framework of Appraisal Theory within a contextualized analysis, this paper reveals that the trial judge and the appellate judges employ differing amounts of evaluative expressions in reaching their decisions. I argue that evaluative language functions as a discursive strategy for negotiating justice, encompassing the narration of legal facts and the construction of legal arguments across different levels of the court system. Furthermore, through an examination of discrepancies between the two language versions, I contend that evaluative expressions, particularly the degree of attitude within the Appraisal Framework, warrant attention in the practice of legal translation. This attention is crucial for achieving a consistent level of emotive entropy in both language versions.

Titanium alloys are broadly used in the medical and aerospace sectors. However, they are categorized within the hard-to-machine alloys ascribed to their higher chemical reactivity and lower thermal conductivity. This aim of this research was to study the impact of the dry-end-milling process with an uncoated tool on the produced surface roughness of Ti6Al4V alloy. This research aims to study the impact of the dry-end milling process with an uncoated tool on the produced surface roughness of Ti6Al4V alloy. Also, it seeks to develop a new hybrid neural model based on the training back propagation neural network (BPNN) with swarm optimization-gravitation search hybrid algorithms (PSO-GSA). Full-factorial design of the experiment with L27 orthogonal array was applied, and three end-milling parameters (cutting speed, feed rate, and axial depth of cut) with three levels were selected (50, 77.5, and 105 m/min; 0.1, 0.15, and 0.2 mm/tooth; and 1, 1.5, and 2 mm) and investigated to show their influence on the obtained surface roughness. The results revealed that the surface roughness is significantly affected by the feed rate followed by the axial depth. A 0.49 µm was produced as a minimum surface roughness at the optimized parameters of 105 m/min, 0.1 mm/tooth, and 1 mm. On the other hand, a neural network having a single hidden layer with 1–20 hidden neurons, 3 input neurons, and 1 output neuron was trained with both PSO and PSO–GSA algorithms. The hybrid BPNN–PSO–GSA model showed its superiority over the BPNN–PSO model in terms of the minimum mean square error (MSE) that was calculated during the testing stage. The best BPNN–PSO–GSA hybrid model was the 3–18–1 structure, which reached the best testing MSE of 3.8 × 10−11against 2.42 × 10−5of the 3–8–1 BPNN–PSO hybrid model.
SLM based Circular (6, 2) mapping scheme with improved SER performance for PAPR reduction in OCDM without side information
Authors: Singh Mohit Kumar , Goel Ashish
Published: November 2023

Like OFDM, OCDM signal also suffers from high PAPR. SLM is an attractive PAPR reduction method but it needs to transmit the information regarding phase sequence i.e. SI to the receiver, which results in reduction in SE and data rate. Various SLM based SI free and SI embedding schemes are available in the literature. In this paper, different possible quaternary to 8-QAM mapping schemes for SI free SLM based PAPR reduction in OCDM system are discussed. Moreover, a new mapping scheme to eliminate the SI requirement has also been presented in this manuscript for SLM based PAPR reduction in OCDM system. Proposed Circular (6, 2) mapping scheme doesn’t require SI at the receiving end which results in increase in SE and data rate as compared to standard SLM technique. Random sequence with phase factors {1, −1} is used to generate the phase sequences for the proposed mapping scheme. Also, the analytical expression for SER of Circular (6, 2) mapping scheme over AWGN channel is derived. We have also evaluated the mathematical expression for SER of other possible quaternary to 8-QAM mapping schemes. Computer simulation using MATLAB are also carried out to investigate the performance of all these mapping schemes in terms of PAPR reduction performance as well as SER performance over AWGN and multipath Rayleigh fading channel. Proposed scheme achieves the same PAPR reduction and improved SER performance w.r.t. other six schemes taken into consideration.

Published: November 2023

Objectives

The association between obesity and gastroesophageal reflux disease (GERD) is well-established in adults; however, data in pediatric population is scarce. Our study aimed to assess the association between GERD and health-related quality of life (HRQoL) in overweight children.

Methods

From April to August of 2020, we included children aged 7–18 years who attended the Endocrinological Outpatient Clinic at the Paediatric Institute, University of Debrecen, Hungary. The participants completed two questionnaires: the Pediatric Gastroesophageal Reflux Disease Symptom Questionnaire (PGSQ) and the HRQoL questionnaire (PedsQL). Based on the criteria of the World Health Organization (WHO), the patients were categorized into two groups: an overweight or obese group and a group with normal weight.

Results

A total of 107 children (51 % female, mean age 13.2 years, 46 % overweight or obese) completed the questionnaires. The median PGSQ score was similar in both groups (4.0 (IQR: 1.0–7.8) vs. 3.0 (IQR: 1.0–7.0), p=0.6). However, the total PedsQL score was significantly lower in the children with overweight or obesity compared to those with normal weight (80.1 (71.1–91.0) vs. 88.0 (76.1–94.6), p=0.031). The PedsQL score was lower among overweight patients with GERD symptoms than that of normal-weight patients without GERD symptoms.

Conclusions

Our findings highlight the importance of raising awareness about GERD to enhance the HRQoL and prevent long-term complications in obese children.
Comparison between trans-vaginal and trans-abdominal ultrasound examination of the cervix in the second trimester of pregnancy: a prospective study

Published: November 2023

Objectives

To compare transvaginal (TV) and trans-abdominal (TA) ultrasound assessment of cervical length (CL) at the time of the second-trimester scan for fetal anomalies.

Methods

This was a prospective study including consecutive pregnant women attending the low-risk ultrasound clinic of two fetal medicine centres in Italy. The inclusion criteria were women between 19 + 0 and 22 + 0 weeks of gestation, attending the prenatal ultrasound clinic for the routine second trimester screening for fetal anomalies. The primary outcome was to compare the CL measurement obtained at TV compared to TA ultrasound; the secondary outcome was to report the inter and intra-observer variability of CL measured with the two different approaches. All women underwent TV and TA assessment of the cervix performed by two experienced certified operators, blinded to each other. Intra-class correlation coefficients (ICC) and Bland–Altman analyses were used to analyse the data.

Results

Two hundred and fifty women were included in the analysis. All women had anteverted uterus. The mean gestational age at ultrasound was 20.7 ± 0.7 weeks; 1.2 % (3/250) scans were performed at 19 weeks, 49.2 % (123/250) at 20 weeks, 44.8 % (112/250) at 21 weeks and 4.8 % (12/250) at 22 weeks of gestations. Identification of the major landmarks of CL at TA ultrasound was achieved in all the included cases. There was good reliability between CL measured at TA (ICC 0.95, 95 % CI 0.93–0.97 for observer 1 and 0.92 %, 95 % CI 0.89–0.94 for observer 2) and TV ultrasound 0.97, 95 % CI 0.96–0.98 for observer 1 and 0.96, 95 % CI 0.95–0.97 for observer 2). There was also good reliability between the two observers for both the TA and TV assessment of the CL. Mean TA CL was 41.4 ± 5.5 for observer 1 and 40.5 ± 4.8 for observer 2 with no significant differences between the two measurements (mean difference 0.92 mm, 95 % CI −9.7 to 11.2). Likewise, there was no difference between the CL measured at TV ultrasound between the two observers (mean difference −0.83 mm, 95 % CI −5.97 to 4.30). Finally, there was no difference in the mean CL measured at TA compared to TV, either considering the overall population of women (mean difference: −0.43, 955 CI −8.65 to 7.79), or when stratifying the analysis according to the parity status and the operator.

Conclusions

Among experienced operators, there was no difference between TV and TA ultrasound assessment of the CL at the time of the routine anomaly scan for fetal anomaly.
Elite Politicians or Ordinary Citizens? Decree Making and Political Friendship in fifth-century Athens
Authors: Barbato Matteo
Published: November 2023

This article aims to advance our understanding of Athenian politics through a quantitative study of the proposers of decrees in the Assembly during the fifth century BC. Based on the accounts of Greek historians, biographers and orators, scholars have traditionally envisioned Athenian politics as dominated by an elite whose members competed for power and prestige and controlled the Assembly through dynamics of political friendship. Recent studies of the decree proposers attested in the epigraphical and literary sources have questioned this model. They have shown that, at least during the fourth century, political initiative was not the prerogative of an elite but was rather widespread among ordinary citizens. Yet, the traditional, elite-centred view of Athenian politics is still widely supported among scholars working on the fifth-century democracy. This article challenges this view through a comparative study of the respective pictures of fifth-century decree proposing provided by the literary and epigraphical evidence. By means of statistical tests and analyses, it argues that, while wealth certainly gave elites an advantage in the Assembly through rhetorical training as well as an edge in the run for elective offices, Athenian democracy since the fifth century provided occasional proposers and ordinary citizens with significant pathways for exerting political agency. By reviewing the problematic evidence for the practice of proposing decrees through proxies, this study also shows that the significant level of popular participation attested in the observed data was not a by-product of political friendship, and that Athenian democracy since its early history encouraged models of political aggregation which could cut through friendship groups and enable forms of participation not limited to passively supporting one’s political leaders.
Ruling through Fear. Cyrus the Great in Xenophon’sCyropaedia
Authors: Zaccarini Matteo
Published: November 2023

This paper explores Xenophon’s depiction of Cyrus the Great as a ruler in the Cyropaedia. Xenophon’s Cyrus is often regarded by the scholarship as an ideal, benevolent leader sincerely concerned with virtue, friendship, and honour-related dynamics. However, it is clear that Cyrus equally resorts to malicious and divisive means, employing psychological subjugation, fostering mutual rivalry among his friends, and weakening his subjects. His actions ultimately arouse fear, envy, and insecurity, as Cyrus displays some of the typical features of a tyrant. Xenophon possibly meant to show how Cyrus, by successfully balancing different and contrasting aspects, succeeded in maintaining power no matter the costs by ‘domesticating’ his subjects.

The steady laminar flow of an incompressible Newtonian fluid in a porous annular duct with accelerated rotating walls is investigated. The flow is located in the polar plane and is driven by suction and injection at the walls. As required by conservation of mass with zero axial velocity, the fluid is injected into one of the cylinders, which becomes the upstream cylinder, and suctioned into the other, which represents the downstream cylinder. Only the case of the downstream cylinder at rest is examined. The duct gap ratio, the velocity ratio comparing the radial and azimuthal velocities, the Reynolds number, and the velocity coefficient that compares the fluid velocity at the upstream and downstream cylinders are the four parameters of the problem. The purpose of this research is to identify the prerequisites for the flow’s existence and determine how the aforementioned variables affect the flow velocity and pressure gradients at a fixed Reynolds number. The Navier–Stokes equations are replaced by the polar-plane vorticity equation, which is solved using the similarity-solutions method. The shooting technique, including the fourth-order Runge–Kutta algorithm, is used to produce numerical solutions. From the findings, physical understandings of the flow are derived. More specifically, we discover an unexpected interior zone where the fluid is perpetually at rest even while flow is present. The only solution found corresponds to the case of the inner cylinder upstream and rotating provided that the velocity ratio does not exceed the threshold of 0.1 with a velocity coefficient greater than 1.

El crecimiento urbano ha afectado a zonas agrícolas altamente productivas por la expansión horizontal hacia las periferias de las ciudades. La ciudad de Puebla presenta un acelerado crecimiento en la zona norponiente derivado de la creación de la Reserva Territorial Atlixcáyotl que ha afectado al territorio de San Bernardino Tlaxcalancingo y ha desvalorizado la identidad cultural y los usos y costumbres de los habitantes de la localidad, siguiendo patrones basados en intereses particulares y en la especulación inmobiliaria por una planeación urbana que orientó el crecimiento urbano hacia esta zona. Lugar donde se encontraban zonas agrícolas destinadas al cultivo del nopal, que ha sido la base económica por décadas. Derivado de lo anterior, el objetivo es analizar el crecimiento urbano de la Reserva Territorial Atlixcáyotl en San Bernardino Tlaxcalancingo en los últimos 30 años, identificando los factores de mayor influencia para el cambio de uso del suelo, así como las afectaciones a las zonas agrícolas y actividades comunitarias. La metodología utilizada parte de un análisis espacial a través de Sistemas de Información Geográfico con base en tres series de tiempo de la carta de uso de suelo y vegetación entre 1990, 2000 y 2020 para identificar las principales permanencias, transiciones y cambios que muestren el decremento de las zonas agrícolas e incremento de las zonas urbanas. Aunado a lo anterior se hizo una revisión teórica que sirvió como base para conocer el enfoque de diversos autores acerca del tema abordado. Finalmente se presentan los resultados a través de cartografía y datos que muestran cómo ha sido la dinámica de cambio de uso de suelo del territorio y como ha afectado a pueblos con una identidad prehispánica que se ha preservado a través del tiempo.

La cartografía es una disciplina utilizada para diversos estudios urbanos, debido a la importancia que tiene la representación gráfica del territorio en el proceso de análisis de las problemáticas Sin embargo, actualmente existen posiciones que toman a la cartografía como un elemento grafico sin ningún uso, el cual ignoran durante la consolidación de estrategias y ejecución de acciones. La presente investigación desarrolla un análisis acerca de la percepción de alumnos de la Facultad de Arquitectura respecto a la importancia de la cartografía y su aplicación en el territorio, con el objetivo de aportar referentes de consolidación del uso de esta herramienta. Para lo cual se aplico un cuestionario con preguntas cerradas y abiertas respecto al uso y aplicación de la cartografía a a 136 alumnos. Los encuestados consideran que el conocimiento de la cartografía y el territorio es adecuado para su profesión (97.8%), la aplicación más común son las herramientas de Google Eart (69.2%), siguiéndolas Arc Gis o Qgis (39.8.%), en su entorno escolar y laboral, la mayoría han utilizado la cartografía en el desarrollo de proyectos de investigación dentro de sus diferentes materias, ya que les permite representar, analizar y conocer territorios sin tener la necesidad de trabajar en campo. Por lo que se concluye que la cartografía en los estudios urbanos proporcionan herramientas útiles durante la elaboración de investigaciones y formación academica en las propuestas integrales sobre el territorio urbano.
Aislamiento y cinéticas de crecimiento de levaduras presentes en vinazas tequileras

Published: November 2023

Durante la elaboración del tequila, obtenido de la fermentación de jugo de agave, se generan aguas residuales conocidas como vinazas, las cuales contienen elevada carga orgánica, pH ácido, fenoles, furfurales y otros compuestos que en conjunto dificultan su tratamiento y elevan los costos del proceso de producción. Ante esto, la economía circular, funge como una alternativa para la reutilización de las vinazas como materia prima para la producción de etanol por medio de levaduras. Sin embargo, las vinazas contienen compuestos inhibitorios del crecimiento levaduriforme, por lo cual, resulta necesario utilizar levaduras mejor adecuadas a estas condiciones. Debido a esto, la propuesta del presente trabajo consiste en el aislamiento de una levadura presente en vinazas tequileras y determinar su cinética de crecimiento con el fin de evaluar su uso posterior en una biorrefinería para la producción de etanol a partir de vinazas. Las levaduras se aislaron por el método de diluciones seriadas en medio sólido Agar dextrosa Sabouraud (SDA). Posteriormente, el crecimiento celular fue evaluado en un caldo Yeast-extract Peptone Dextrose (YPD) a tres concentraciones de glucosa, 10, 60 y 90 g/L y se determinó el rendimiento de sustrato en masa (Yx/s) y la tasa específica de crecimiento (μ). La velocidad específica de crecimiento fue similar, ≈ 0.2 h-1, para las concentraciones de glucosa evaluadas. El mayor valor en rendimiento Yx/s fue de 0.140 ± 0.025 gbiomasa/gglucosa a 10 g/L y el mayor porcentaje de remoción de sustrato fue alcanzado a 90 g/L (99.79 ± 0.03%). Dada la gran capacidad de la levadura para metabolizar el sustrato y convertirlo rápidamente a biomasa resulta ser una levadura apta para su uso en fermentación alcohólica con la proyección a su uso en economía circular de residuos tequileros.

Published: November 2023

El presente trabajo pretende contribuir a tener un panorama sobre la situación en la que se encuentran los grupos étnicos en la frontera México-Belice, partiendo del supuesto de que ésta es pluriétnica pues en ella convergen diversas poblaciones. El análisis se realiza a partir de variables como el fenómeno migratorio y la concepción de los derechos humanos como normas protectoras de las tradiciones, los usos y costumbres de los diferentes grupos étnicos que cruzan la frontera, así como el desenvolvimiento en las dinámicas de una frontera, donde está de por medio un país (Belice) que es un ejemplo de un Estado Nacional que todavía no ha incorporado la protección de derechos indígenas en su Constitución y leyes en diversos ámbitos como el relativo a la propiedad y uso de tierra.
Militarización y sistema de justicia penal. Reflexiones desde la seguridad
Authors: Guerrero Agripino Luis Felipe , Martínez Nava Susana
Published: November 2023

En la actual administración del Gobierno mexicano se ha apostado por el empleo de las Fuerzas Armadas para una gran variedad de tareas que van más allá de la seguridad nacional y la seguridad pública. La Guardia Nacional, que no es una corporación civil sino, en esencia, militar, ahora cuenta con facultades para la prevención e investigación de los delitos. Se sostiene la tesis de que el sistema de justicia penal se ve afectado al contar con una corporación esencialmente militar que realiza labores que deben corresponder a una policía científica.
La transversalidad de la perspectiva de género en la legislación local del estado de Guanajuato a partir de la nueva Ley Orgánica Del Poder Legislativo Del Estado
Authors: Domínguez López Velarde Alejandro
Published: November 2023

A partir de 2016 se transversaliza la perspectiva de género en el Poder Legislativo del Estado de Guanajuato, al incorporar, dentro de la Ley Orgánica del Poder Legislativo del Estado de Guanajuato, la obligación de considerar, dentro de las iniciativas, el impacto de género. Sin embargo, no se ha materializado tal disposición en la legislación, siendo necesaria la visión transversal de la perspectiva de género en las leyes para abonar a disminuir la brecha de desigualdad desde la normatividad estatal.
