Aim. To assess the characteristics of ST-segment elevation myocardial infarction (STEMI) in patients with metabolic syndrome (MS) in the presence and absence of metabolic-associated fatty liver disease (MAFLD).

Material and methods. A total of 144 patients with STEMI and MS, admitted for primary coronary angiography and percutaneous intervention (PCI): 71 patients with MAFLD (group 1, age 62,9 (59,9;66,0) years, 17 women); 73 patients without MAFLD (control group, age 63,2 (59,1;66,8) years, 17 women). The examination program included transient hepatic elastography, determination of cardiac troponin I (cTnI) upon admission (cTnI-1) and after 24 hours (cTnI-24), mean platelet volume (MPV), transaminases, gamma-glutamyl transferase, concentration of cytokeratin-18 (CK-18) fragments.

Results. Patients with STEMI in combination with MAFLD are characterized by the predominance of a high thrombotic load (TIMI thrombus grade 5, p=0,048), requiring two-stage PCI (p=0,018), an increase in the platelet count and MPV, a decrease in the resolution of ST elevation after primary PCI, a higher transaminase and liver dysfunction markers’ level. The main condition for these differences is steatohepatitis, which determines significant troponin elevation (p<0,01) and is a predictor of high thrombus load (p=0,016), increased MPV (p=0,044) and a factor of adverse events during 18 months after acute coronary syndrome (p=0,00035). The inclusion of the CK-18 criterion in the multivariate model makes it possible to improve the quality of the initial clinical model for predicting subsequent coronary events in the case of STEMI-MAFLD combination with an increase in the area under the ROC curve from 0,788 (95% confidence interval (CI), 0,69-0,89) to 0,648 (95% CI, 0,52-0,78) (DeLong test, p=0,044).

Conclusion. MAFLD in patients with STEMI is combined with an increase in the severity of coronary thrombosis and difficulties in primary PCI, the main condition of which, as well as adverse events after acute coronary syndrome, is steatohepatitis.

The viral infection and pandemic of coronavirus infection 2019 (COVID-19) was characterized not only by high morbidity and in-hospital mortality, but also by an increase in the mortality of patients after hospital discharge. At the same time, differences were noted in hospitalization rate, the number of complications and mortality of patients, and mortality rate between different pandemic waves from 2020 to 2023.

Aim. To compare the 18-month post-hospital mortality rate of patients between three COVID-19 variants (Alpha, Delta and Omicron).

Material and methods. In this prospective, single-center, non-randomized continuous study, 2400 medical records of patients with the Alpha variant (2020), 1826 with the Delta variant (2021) and 997 with the Omicron variant (2022) were analyzed. The end point was all-cause mortality during the follow-up period.

Results. There were following differences in clinical and demographic characteristics in the context of COVID-19 strains: more women were hospitalized in the Delta and Omicron waves; in the Omicron wave, patients were older. Also, comorbid patients were more common with the Delta and Omicron variants than with the Alpha (in chronic obstructive pulmonary disease, hypertension and heart failure), but chronic kidney disease was more common with the Alpha and Omicron variants. The groups differed significantly in mortality, with the maximum being with Delta and the minimum with Omicron, and the maximum mortality with Delta was observed in the first 90 days after discharge. Between 12 and 18 months, survival estimates decreased most for patients hospitalized in the Delta wave, which is determined by the risk of long-term cardiovascular consequences.

Conclusion. Clinical and demographic differences between patients with different COVID-19 variants, as well as a significant difference in the mortality rate of patients of different waves, emphasize the importance of a personalized approach to treatment and long-term post-hospital monitoring.
Un-Mögliche Solidarität: Zivile Seenotrettung zwischen radikaler Demokratie und kolonialen Kontinuitäten
Authors: Gebhardt Mareike
Published: December 2023

Drawing from Jacques Derrida's notion of the impossible, the paper discusses different understandings of solidarity. It questions a notion of solidarity where it is deemed possible onlyunder conditions of similarity. To show how the similarity assumption hardens into an authoritarian, racist hermeticism of solidarity, I scrutinize the far-right's invocation of solidarity in reference tomigration politics. In contrast to hermetic solidarity, the paper introduces solidarity as a praxis indifference. It conjures an understanding of solidarity as both possible and impossible among radically different peoples and groups. I elaborate this argument in conversation with different strandsof critical theory – deconstruction, radical democratic theory, queer_ and Black feminist theory– to unearth solidarity's racist and androcentric residues. I argue for an intersectional reading ofsolidarity, through which the different theorizations are channeled into a critique of solidarity thatproblematizes the inequalities of solidarizability. Lastly, to connect theory with praxis, I refer toe xamples from civil Search and Rescue in the Mediterranean, where solidarity with the Other isurgently needed and often violently neglected.
On the Problem of Reducing the Equations of Rigid Body Dynamics in Hyperbolic Space
Authors: Makeev Nikolay N.
Published: December 2023

An affine transformation of the space of velocities of the system of equations of motion of an absolutely rigid body is given, moving relative to the center of inertia in a hyperbolic space of constant negative curvature. The movement of the body occurs under the influence of a system of gyroscopic forc-es and a constant servo generalized force specified by the power screw. The structure of gyroscopic forces is given by special conditions containing characteristic constant parameters (gyroscopic coefficients). For the transformed system of equations under given structural-kinetic constraints, the system is reduced to an integro-differential equation obtained with respect to one of the components of the shear rate screw. An example of exact linearization of the transformed system of equations is given.

Le 20 février 2018, une toxi-infection alimentaire collective (TIAC) est survenue dans un organisme de restauration collective de Saint-Denis alimentant les forces armées françaises sur l’île de la Réunion, dans l’Océan Indien.
L’investigation de cette TIAC été entreprise parmi les participants aux repas (110 convives) suspectés afin de déterminer la nature et l’origine du foyer. L’enquête-cas témoin a été réalisée grâce à une équipe pluri-disciplinaire et interministérielle.
Onze cas et 24 témoins ont été identifiés parmi les participants. Les symptômes habituels de scombrotoxisme histaminique ont été observés (érythème cervico-facial prurigineux, céphalées, diarrhées). Les symptômes sont apparus dans les minutes qui ont suivi le repas. Une résolution rapide des symptômes a été observée chez la plupart des patients avec un traitement anti-histaminique et anti-diarrhéique. Le seul plat statistiquement associé à la maladie était un plat à base de thon (OR = 95, IC 95 % [11,7 - 774,7]). Des concentrations d’histamine dans les échantillons de thon ont été détectées avec des concentrations allant de 2 476 mg/kg à 2 921 mg/kg, soit plus de dix fois la concentration maximale autorisée par la réglementation européenne.
Cette intoxication alimentaire, due à une concentration trop élevée d’histamine dans le poisson, est souvent confondue avec une réaction allergique. Le thon et d’autres poissons scombridés comme le maquereau sont souvent impliqués dans ce type d’intoxication collective. Néanmoins, d’autres denrées alimentaires peuvent être à l’origine de ce type de signes cliniques.

Published: December 2023

Fréquentes en soins primaires, les morsures animales peuvent engager le pronostic vital, fonctionnel ou esthétique, et sont à haut risque d’infection. À partir d’une étude rétrospective descriptive des morsures animales admises à l’Hôpital d’instruction des armées Sainte-Anne, de janvier 2015 à juin 2017 via le Service d'accueil des urgences, et d’une évaluation des connaissances et pratiques auprès des internes, un protocole de prise en charge est proposé.

Sur 229 patients, 140 étaient mordus par un chien, 66 par un chat, 8 par un rongeur. La plaie siégeait aux membres supérieurs (59 %), aux membres inférieurs (27 %) et à l’extrémité céphalique (12 %). Le taux de surinfection était de 18 %. La plaie était irriguée sous pression dans 27 % des cas, suturée dans 16 % des cas. Une antibiothérapie a été instaurée chez 79 % des patients. Seize patients ont été hospitalisés. Comparés à la littérature, nos résultats correspondent à ceux observés pour une population citadine, adulte, de France métropolitaine. Le traitement est guidé par l’anamnèse, l’examen clinique et la microbiologie. Le lavage de la plaie par irrigation sous pression, l’antibiothérapie et la prophylaxie antitétanique doivent être systématiques.

Published: December 2023

ÖZ

Doğal ve beşeri ekosistemler açısından karmaşık etkilere sahip olan kuraklıklar, genel olarak uzun süreli yağış eksikliği şeklinde tanımlanan ve oldukça tehlikeli sonuçları olan bir afet türüdür. İklim değişikliği ile birlikte artan sıcaklık ve yağış değişkenlikleri, kuraklık olaylarının sıklığı, şiddeti ve süresini değiştirmektedir. Artan sıcaklıklar ile birlikte bir sıcak nokta haline gelen Akdeniz Havzası, bu fenomen karşısında oldukça kırılgan hale gelmiştir. Bu çalışmada, ülkemizin Batı Akdeniz kesimi için temin edilen 1980-2019 yılları arasındaki günlük sıcaklık ve yağış verileri kullanılarak, Standartlaştırılmış Yağış Evapotranspirasyon İndisi (SPEI) yardımıyla ekstrem kurak dönemler 3-6-12 aylık ölçeklerde araştırılmıştır. Hesaplamalarda yağış faktörünün yanında, sıcaklık ve buharlaşma faktörlerini de birleştiren SPEI yönteminin, ekstrem kurak dönemleri belirlemede başarılı olduğu gözlemlenmiştir. Elde edilen sonuçlara göre; SPEI-3 ve SPEI-6 aylık zaman serilerinde 1981, 1985, 1989, 1990, 2000, 2007 ve 2008 yılları; SPEI-12 aylık zaman serilerinde ise 1990-1991, 2000-2001, 2004-2005, 2007-2008 ve 2016 yılları ortak ekstrem kurak yıllar olarak tespit edilmiştir. 3 ve 6 aylık ekstrem kuraklıkların genel olarak yaz ve sonbahar aylarında gerçekleştiği belirlenmiştir. Ekstrem kurak ayların en fazla tespit edildiği istasyon olan Burdur’da, 2015 ve 2018 yılları arası şiddetli şekilde kurak geçmiştir. Genel olarak, kıyı kesimlerde nemli olma eğilimi, iç kesimlerde ise kuraklaşma eğilimleri tespit edilmiştir. Özellikle iç kesimlerde tarımsal sürdürülebilirlik ve su yönetimi üzerine yapılacak çalışmalar, şiddetli kuraklık şartlarına karşı adaptasyon ve zararları azaltmak açısından oldukça önemlidir.

Geyik Dağları, Geç Kuvaterner boyunca yoğun ve tekrarlanan buzullaşmalara maruz kalmıştır. Güncel bir buzulun varlığı bölgede yapılan daha önceki çalışmalarda doğrulanmamış veya tespit edilememiştir. Bölgede yerel gezgin olan Hasan Hüseyin Kahrıman’nın 27 Ekim 2023 tarihinde buzul varlığını sosyal medya aracılığı ile aktarması üzerine buzulları tanımlamak ve yerlerini belirlemek için uzaktan algılama yöntemleri kullanılmış ve Geyik Dağı’na yapılan arazi çalışması ile güncel buzulların varlıkları doğrulanmıştır. Bu çalışma aynı zamanda bilimsel olarak Geyik Dağı’nda güncel bir buzulun varlığını tanımlayan ve doğrulayan ilk çalışmadır. Belirlenen yayılış alanları üzerinden buzul modellemesi, ELA (Equilibrium Line Altitude) hesaplama araçları, bakı ve eğim intersect (kesiştirme) analizleri ile sirk morfometrisi yöntemleri kullanılarak buzulların ve içerisinde yer aldıkları sirkler ile yakın çevresinin özellikleri nicel verilerle ortaya konulmuştur. Buzul modellemesi neticesinde Geyik Orta Buzulu’nun toplam 6000 (±300) m2, Doğu Buzulu’nun 2030 (±100) m2 toplamda ise Geyik Dağı’ndaki buzulların 8030 (±480) m2 alana sahip olduğu tespit edilmiştir. Buzulların ortalama olarak uzunlukları 95 m (metre), ELA değeri ise 2619 m olarak hesaplanmıştır. Buzulların 12-30˚ eğim değerleri arasında ve tamamen kuzey bakılı alanlarda bulundukları tespit edilmiştir. Buzullar ve sirklerin morfolojik özellikleri, yüksek rakım, bakı özellikleri ve yüksek kar birikimi Geyik Dağı’ndaki buzulların bu kesimlerde korunmasına pozitif olarak etki etmiştir. Buzullar üzerinde yapılan karşılaştırmalı uydu görüntülerinde 06.09.2010 tarihinden günümüze kadar buzulların alansal olarak %50’sinden fazlasının erdiği ve önümüzdeki yıllarda etkisini giderek arttıran küresel ısınma ile beraber 5 yıl içerisinde tamamen ortaya kalkacağı tahmin edilmektedir.
„Što dalje od uske političke historije“ – Mirjana Gross i modernizacijska stremljenja u jugoslavenskim historiografijama (1960–1991)
Authors: Antolović Michael
Published: December 2023

Mirjana Gross’s program of historiographical modernization, in the form of a comprehensive social history aimed at overcoming the limitations of traditional histoire événementielle, was not limited to her native Croatian historiography but also had a direct influence on the modernization aspirations of Yugoslav historiographies during the so-called “late socialism.” Starting from the assessment that, from the early 1960s, Mirjana Gross was a key promoter of the “new history” within the community of Yugoslav historians, the paper tries to analyze her program of historical modernization, the resistance it encountered, as well as its overall achievements in Yugoslavia during that time.
Soledades y desiertos: un estudio sobre las vivencias de la soledad en jóvenes universitarios del sureste español
Authors: Caballero Cala Verónica
Published: December 2023

La importancia social que está adquiriendo la soledad en las sociedades contemporáneas ha convertido esta experiencia en objeto de investigación de disciplinas como la antropología. El abordaje antropológico, tratando de redibujar los análisis tradicionales en clave individual y psicológica, busca ofrecer una lectura sociocultural y colectiva de esta realidad. Esta investigación analiza, mediante el método Photo Elicited Interview (PEI), la vivencia de la soledad en jóvenes de Almería, entre 19 y 24 años, en el contexto post-COVID desde las coordenadas de la recién surgida antropología de la soledad. Los resultados del análisis se organizan en tres niveles: subjetivo-corporal (soledades), interpersonal (procesos de desertización) y sociocultural (desiertos), conectando la dimensión subjetiva del fenómeno con los discursos sobre las trasformaciones en un medio ambiente social y relacional. Por su complejidad, este artículo desmenuza únicamente los hallazgos relativos al nivel subjetivo-corporal. La interpretación de las cuarenta entrevistas permitió reconocer seis dimensiones de la vivencia de la soledad: la emocional, la física, la existencial, la identitaria, la relacional y la transformadora; todas ellas en estrecha interacción con los factores que las agravan, como son la discriminación y el rechazo, la vida en la ciudad, la competitividad capitalista, el nihilismo y, de una manera ambivalente, las redes sociales (la digitalización neoliberal), la psicología y el aislamiento derivado de la COVID. Los hallazgos revelan una problemática de enorme calado y refuerzan la necesidad de adoptar una comprensión corporal, relacional y sociopolítica de la soledad.
“Es mucho más fácil esquivar jeringuillas, que bombas”: aproximación etnográfica al movimiento antivacunas en Cataluña
Authors: De Llobet Viladoms Patricia
Published: December 2023

El estallido de la pandemia producida por el virus SARS-CoV-2 tuvo un gran impacto social y económico en las sociedades de todo el mundo. Las diferentes medidas impuestas para intentar controlar los contagios fueron percibidas como arbitrarias y como un ataque a la libertad individual por muchas personas, especialmente por los colectivos antivacunación. Durante el transcurso de la pandemia, estos grupos encontraron una oportunidad política inmejorable, primero con la carrera de las farmacéuticas para sintetizar las vacunas y, a continuación, a lo largo de la campaña de vacunación, tiempo en el que fueron ganando protagonismo mediático y social. Los colectivos antivacunas se mostraron especialmente activos durante este periodo a través de Internet y las redes sociales; haciendo uso de la acción colectiva, convocaron protestas y manifestaciones como forma de presión contra las medidas que consideraban injustas. Este trabajo es una aproximación etnográfica al movimiento antivacunas en Cataluña en tiempos de la COVID-19 cuyo objetivo es caracterizar el fenómeno para conocer los distintos perfiles presentes en el movimiento, sus discursos y sus reivindicaciones.

This protocol provides detailed instructions for transient expression of PIP3/PI(3,4)P2-selective PH domain-based reporters for subsequent live-cell imaging by total internal reflection fluorescence microscopy. Instructions are also provided for execution of perturbation experiments using growth factors or inhibitors that act through the PI3K signalling pathway. The protocol was originally developed with advice from Dr York Posor (Vanhaesebroeck Lab, University College London), Dr James Burchfield (University of Sydney) and Dr Alison Kearney (David James Lab, University of Sydney). The protocol is routinely used in our lab for experiments with HeLa cells. It has also been used with mouse embryonic fibroblasts and lung adenocarcinoma A549 cells, however the complete medium (CM), seeding densities and transfection conditions differ for each cell line. We culture our cells without antibiotics except during live-cell imaging as indicated. For subsequent data analysis, please refer to the pipeline provided on the Open Science Framework under doi: 10.17605/OSF.IO/4F69N.

Published: December 2023

Roasting is considered the commonest processing method applied to foods, it affects both phytochemicals and sensory attributes. In the present study, the effect of varying roasting parameters on sensory attributes was determined, as well as scavenging property against free radicals (DPPH) and polyphenolic content (TPC and TFC) of whole peanut kernels. Whole peanut kernels were roasted at different temperatures (130-150 °C) with various durations (5-20 min). Finding revealed that peanuts roasted at 130, 140, and 150 °C for 15, 10, and 5 min, respectively, received significantly the highest (p<0.05) sensory scores in all the parameters investigated. Therefore, they were selected for TPC, TFC, and DPPH assays. All three assays were found to increase during roasting compared to the unroasted counterpart. Peanuts that were roasted at 140 °C for 10 min, had the highest total phenolic contents of 67.26 ± 1.77 mg GAE/g while those roasted at 150 °C for 5 contained the highest TFC of 12.91 ± 0.56 mg QE/g. The highest DPPH radical scavenging activity was detected in the sample roasted at 140 °C for 10 min with an IC50 value of 417.44 μg/mL. Roasting significantly affected the bioactive contents as well as the scavenging activity of the whole peanut.
Wine quality analysis by the structural causal model (SCM)
Authors: Kurtanjek Želimir
Published: December 2023

Bayes network modelling for structural causal analysis between wine physicochemical data and quantitative human quality blind assessments is applied. The large dataset of white and red "Vinho Verde'' wine samples from Portugal, which was available from an open data repository for machine learning at the University of California at Irving, was analysed. The dataset contains 4898 white and 1599 red samples evaluated by blind tastes by a minimum of 3 sensory assessors and 12 physicochemical properties. The casual effects of wine analytic data on human quality evaluations are evaluated numerically by Bayes neural networks for adjusted sets of the covariates as marginal distributions and presented graphically as partial dependence plots. Structural causal analysis revealed important differences between the most important variables for quality predictions and the individual causal effects. Bayes neural network models of the partial dependencies show more pronounced nonlinear effects for red wines compared to white wine quality. The artificial intelligence models with boosted random decision tree forests for untrained wine samples yield a 5% relative standard error of predictions compared to 12% for the linear models and ordinary least squares estimation. For red wine, the most important direct causal quality effects are caused by alcohol, volatile acidity, and sulphates. Alcohol improves quality with a maximum plateau at 14%, while volatile acidity has a strong proportional negative effect. The effect of sulphates is highly nonlinear with maximum positive effect at a concentration of 1 g/L of K2SO4. For the white wine samples causal effects are linear with positive effects of alcohol and negative effects of volatile and fixed acidity. The developed structural causal model enables evaluation of targeted wine production interventions, named as “doing x, do(x) models”, as restructured adjusted Bayes networks. It leads to potential applications of artificial intelligence in wine production technology and process quality control.

Authors: Drača Nela , Flanjak Ivana , Bilić Rajs Blanka
Published: December 2023

Pollen grains are located on the anthers of the flowers, bees collect them and mix them with secretions from their salivary glands and nectar and carry them to the hives in the baskets situated on their hind legs. According to the chemical composition, bee pollen is a mixture of proteins, fats, carbohydrates, vitamins and other useful substances for the development of bees in the hive. Due to its nutritional value and potential healthful properties, it is valuable product for beekeeper’s income. The aim of this research was to evaluate the physicochemical characteristics of bee pollen in relation to the period of collection and geographical origin from different localities in Virovitica-Podravina County. Eleven bee pollen samples were collected from stationary apiaries in the period of April and May 2022.Palynological analysis showed that dominated pollen in five samples was pollen from Brassica sp.; Malus spp. and Salix spp. pollen dominate in two bee pollen samples while two samples had dominating pollen coming from Asteraceae family. Physicochemical analysis showed that pollen collected in the period of April had a lower proportion of ash, total fat and phenols, but a higher proportion of moisture content, proteins and carbohydrates.

Published: December 2023

The potential of extract from roselle calyx on quality attributes of chicken patties marinated without extracts [plain (P1) and prepared with 0.01% butyl hydroxyl anisole; BHA (P2)] and with extract [soaked in roselle calyx extracts concentrations at 0.005% (P3), 0.01% (P4), 0.015% (P5) and 0.02% (P6)] were evaluated. Sensory qualities, cooking loss, product yield and colour [lightness (L*), redness (a*) and yellowness (b*)] were determined on freshly prepared patties and the production cost was evaluated. Total bacterial count, TBC (log10 CFU/g), water holding capacity; WHC (%), pH and lipid oxidation (mg MDA/kg) were determined on days 0, 7, 14 and 21 of cold (4 °C) storage. Patties flavour of 5.65±0.01 (P6) was higher (p<0.05) than in other treatments and the least in P1 (3.96±0.23). Cooking loss ranged from 20.24± 0.11% (P6) to 26.55± 0.01% (P1). Product yield of 79.8±0.7% (P6) was the highest, which varied significantly from other treatments. Lightness in P1 - P6 was darker than normal, with the highest L* = 42± 2.43 (P1) and the least L* = 36.44± 0.15 (P6). Redness was the least in P1 (a* = 16.85± 1.32), which varied significantly (p<0.05) from other treatments. Yellowness in P2 (b* = 54.14±1.35) was the highest, which differs significantly (p<0.05) from other treatments. Production cost varied insignificantly (p>0.05) among the treatments, with (P2 - P6) being significantly (p<0.05) higher than P1, with increasing percentage gain ranging from 0.02% (P2) to 0.78% (P6) relative to P1. On day 21, there were variations (p<0.05) in range for TBC [0.30±0.03 (P6) to 0.48±0.03 (P1)], and WHC [68.78±0.27 (P1) to 80.96±0.37 (P6)], pH [5.21±0.13 (P6) to 5.70±0.18 (P1)]. Lipid oxidation of 0.39±0.04 (P2) and 0.41±0.04 (P6) was similar, but significantly lower than 0.61±0.01 (P3), 0.59±0.04 (P4) and 0.46±0.01 (P5). Thus, among all patties marinated with extracts, those with 0.02% roselle calyx extract maintained better quality, inhibited lipid oxidation and bacteria during storage.

Introduction: Computed tomography angiography (CTA) represents the gold standard as a method for the diagnosis of carotid artery diseases. The current topic is the use of CTA for the evaluation of carotid arteries with a reduction in the dose of contrast agent and dose of ionizing radiation, which, with adequate preparation, would enable the use of this method in some risk groups. The aim of this study was to evaluate the feasibility and image quality of a new low-dose CTA protocol in comparison with a standard protocol.
Methods: Forty patients with recumbent ischemic stroke were included in the study, twenty of whom underwent lowdose CTA, and the remaining twenty underwent a standard CTA protocol of the carotid arteries.
Results: No significant difference was found between the mean values of CT number (Hounsfield unit), signal-to-noise ratio, contrast-to-noise ratio, and subjective assessment of image quality in the comparison of the control and experimental groups. CT dose index, volume, and dose length product were significantly lower in patients who underwent lowdose carotid CTA. There was no significant difference in the degree of carotid stenosis between color Doppler and CTA.
Conclusion: The use of the low-dose protocol for carotid CTA allows the application of this method in risk groups, in which it was previously not possible to perform, with the same image quality in comparison with the standard protocol.
Sueños y delirios de «La Chiquita» y la «Mujer verdugo». Las mujeres criminales en las hojas de Vanegas Arroyo
Authors: Masera Mariana
Published: December 2023

A finales del siglo XIX, la prensa y las hojas volantes de Vanegas Arroyo informan sobre los crímenes cometidos por dos mujeres: María Villa, «La Chiquita» y Guadalupe Martínez Bejarano, «la Mujer verdugo». En ambos casos, no solo sufren la sanción penal, sino que también se las condena por transgredir la norma social del rol de la mujer. El presente trabajo aborda las representaciones de las mujeres transgresoras tanto en la prensa como en la literatura de cordel —así como el proceso de adopción y adaptación de las noticias a las hojas volantes realizadas por el editor mexicano—. Esto último a través del análisis de elementos fundamentales en los impresos populares, como las representaciones de las mujeres en las imágenes, las formas y los géneros poéticos utilizados en el discurso y el uso de la voz femenina.
Epistemologies of Data Visualisations: On Producing Certainties, Geographies and Digitalities in Critical Educational Research
Authors: Hillman Thomas , Macgilchrist Felicitas , Kiesewetter Svea
Published: December 2023

In the age of data-driven research, data visualisations have emerged and proliferated as indispensable tools for understanding complex phenomena. Visualisations can be compelling. They communicate objectivity, efficiency and authority. However, data visualisations are not neutral. They embody and convey particular epistemological perspectives, shaping how knowledge is produced, circulated and understood (D’Ignazio & Klein, 2020; Ratner & Ruppert, 2019; Williamson, 2016). In scholarship, visualisations are, like other scientific practices, ‘designed to make the invisible visible, the evanescent permanent, the abstract concrete’, and in this sense, visualisations are ways in which scholarship ‘discovers the world anew’ (Daston & Lunbeck, 2011, p. 1). This article explores the epistemologies inherent in data visualisations when they are produced within critical studies of the datafication of education. It takes up the call for researchers to interrogate the tensions that arise when the ‘digital...
Development of Model Optical Distribution Point Location Detector System with GIS Approach Method- Case Study in PT. Telkom Witel Bandung
Authors: Budi Budi Herdiana
Published: December 2023

Principally, the validation of the location of the Optical Distribution Point (ODP) device is carried out to match the field data with the data at the center of the system. The current problem is that there are frequent shifts in ODP location data points in the field with the data system at PT. Telkom Witel Bandung because the existing detection system is still manual. This condition directly disrupts the performance of the communication network system so that service to customers is reduced. Therefore, it is necessary to develop a digital and automatic detection system for detecting ODP locations through the use of the Geographic Information System (GIS) method. This method is able to increase the accuracy and efficiency of the travel time to the ODP location point. This study aims to increase the accuracy of the ODP device at different locations through the development of a location point detection system using the geographic information system method approach. The testing technique carried out in this study used two methods, namely the direct method and the GPS field measure method. The test results on the developed geographic information system have been successfully integrated with Google maps and the GPS sensor has been successfully sent to the application. The results of the previous system obtained a location accuracy rate with an error percentage value of 3.6%. While the results of this development system obtained an error percentage value of 1%. Based on the results of the final test, it shows that the system developed in this study produces a better accuracy value than the previous system. In the future, this developed system can be implemented to accurately detect ODP locations for larger numbers and larger areas.

Estudio comparativo de dos métodos para determinar las dimensiones de eritrocitos en los vertebrados
Authors: Palomeque Rico Jesús , Viscor Carrasco Ginés , Palacios L.
Published: December 2023

Se compararon dos metodos para determinar las dimensiones eritrocitarias en varias especies de vertebrados: paloma, gaviota reidora, gallina doméstica, anguila común, rata de laboratorio y el hombre. El primer método fue el de medida directa de las células teñidas en una extensión de sangre por medio de un ocular micrométrico; el segundo método consistió en la medición sobre fotomicrografías obtenidas de suspensiones de hematíes en pasma. Se detectó una reducción de las dimensiones eritrocitarias durante el proceso de preparación del frotis sanguíneo y en algún caso se observó una alteración de la forma en los eritrocitos nucleados. Durante la determinación de las dimensiones de eritrocitos supendidos en palsma, se mantienen las condiciones fisiológicas en el medio ambiente celular, obteniéndose de este modo resultados más fidedignos.

Published: December 2023

Hemos llevado a cabo un estudio serológico, empleando la técnica de fijación del complemento, a partir de 339 animales procedentes de dos explotaciones leonesas donde se habían detectado con anterioridad problemas de pleuroneumonía porcina. El número de sueros positivos fue elevado (73,2%), lo que no sucedió con los títulos, cuyo valor más frecuente fue 40. El porcentaje de sueros anticomplementarios fue muy escaso (0,3% del total). A lo largo de los meses estudiados no se observaron diferencias en cuanto al número de animales positivos pero sí en cuanto a sus títulos. El porcentaje de cerdos seropositivos fue similar en ambas explotaciones, aunque los títulos resultaron más altos en una de ellas.

Published: December 2023

Se realizó un estudio comparativo entre las pruebas de fijación del complemento, ELISA y aglutinación con 2-mercaptoetanol, adaptadas al diagnóstico de la pleuroneumonía porcina, originada por Actinobacillus pleuropneumoniae. Se partió de 339 sueros y se comprobó que la técnica más sensible era el ELISA. La fijación del complemento, aunque no igualó a la prueba anterior arrojó unos resultados aceptables, en tanto que la aglutinación con 2-mercaptoetanol fue, con diferencia sobre las otras dos, la que reveló los peores resultados, tanto en cuanto al número de sueros positivos como en relación con los títulos, por lo que no la consideramos útil para la detección de anticuerpos contra A. pleuropneumoniae.

Se comparan los resultados obtenidos en la determinación de la Aw del queso de Valdeteja (León) por las ecuaciones de Marcos et al (1981), Rüegg y Blanc (1983) y Fernández-Salguero et al (1986), y por la fórmula Aw = 1,00937 - 0,00898 (NaC1) -0,00274 (Cenizas - NaC1), desarrollada en nuestro laboratorio. Esta última dio la mejor respuesta con una precisión de ± 0,008. La de Rüegg y Blanc ofreció también buenos valores. Las de Fernández-Salguero et al fueron asimismo muy precisas, aunque su aplicación a este tipo de queso requiere la introducción de pequeñas modificaciones.

Published: December 2023

En este trabajo se ha estudiado el efecto del estrés de inmovilización en la rata, aplicado durante la gestación. Se ha controlado la duración de la gestación, el número de crías/camada, el sex ratio y el desarrollo corporal de la descendencia desde el nacimiento hasta el destete. Las ratas se someten a 2 horas de estrés de inmovilización (de las 9:00 h a las 11:00 h). Se aplica en diferentes momentos de la gestación: del día 1 al 6 de gestación (Grupo l), del día 17 al 21 de gestación (Grupo 11) y durante toda la gestación (Grupo 111). No se obtienen diferencias significativas en cuanto a la duración de la gestación, número de crías/camada y sex ratio. El estrés aplicado parece influir (p < 0,05) en el % de mortalidad perinatal, en el peso de las crías al nacimiento y su posterior desarrollo hasta el destete. Así determina un menor peso de las crías nacidas en los grupos 11 y 111 y un mayor peso en las crías nacidas en el grupo 1, todo ello con respecto al grupo control y demás grupos experimentales
