Authors: Baidya Tapan K. , Mondal S. K. , Balaram V. , Parthasarathy R. , Verma R. , Mathur P. K.
Published: November 2024

The Precambrian ultramafic-mafic plutonic complex of Nuasahi, Orissa in the Eastern Indian Shield represents at least three suites of magmatic intrusion: (i) an interlayered sequence of enstatitite, websterite (± olivine), dunite, chromitite, harzburgite and orthopyroxenite; (ii) massive gabbroic suite with minor bodies of norite, anorthosite and bands of titaniferous magnetite and (iii) dykes and sills of dolerite and clinopyroxenite. A prominent breccia zone is developed near the interface of the first and second magmatic suites in the eastern part of the complex including the Shankar chromite lode and the ultramafic host of the first suite, and the gabbro-noritic rocks of the second suite. This breccia zone is enriched in Cu-Fe-Ni sulphides and has become the principal site for concentration of PGE, gold and silver. On a whole, Pd dominates over Pt in the sulphide-bearing Shankar chromite lode and the adjacent orthopyroxenite as well as gabbro in this breccia zone. The chromite-sulphide association is the most enriched part for PGE, gold and silver. Ag is positively correlated with Pd. The breccia zone which was developed prior to the gabbroic emplacement into the chromiferous ultramafics. represents a sulphide-rich metasomatic zone leading to maximum concentrations of PGE, Au, Ag in this zone alongwith formation of various sulphides, oxides and silicates. Both Pt and Pd are considerably higher and Ir is lower in the present area than in chromite-sulphide associations from ophiolitic complexes and Alpine-type massifs. Rather, Pt, Pd and Ir values compare better with the chromite-sulphide associations from layered intrusions.
BORROWED ILLUSTRATIONS OF GLOSSOPETRAE WITH SHARK’S HEAD: STENO AND THE VATICAN COLLECTION OF MERCATI
Authors: YAMADA TOSHIHIRO
Published: November 2024

It is well known that fossils of shark’s teeth were named as ‘tongue stones’ (glossopetrae in Latin) because of their similarity in shape to the tongues of animals. However, Nicolaus Steno (1638–1686) decidedly revised this kind of explanation in the latter half of the seventeenth century. He recognized them as shark’s teeth in his treatise of 1667, adopting the figures of a shark head with teeth in its mouth and fossil ‘tongue stones’ borrowed from the then unpublished manuscript on the Vatican mineral collection by Michele Mercati of San Miniato (1541–1593). This article reconsiders the role of the palaeontological illustrations in this process because Mercati himself had recognized the similarity of the shapes of the shark teeth and glossopetrae but he could not neglect the difference of material between them. Although Steno’s skill as a comparative anatomist convinced him of the organic origin of the fossils, there were still problems of sedimentation to solve. We will first review the opinions of early modern naturalists concerning fossil objects and then focus on how Steno solved the problem to pave the way for his epoch-making dissertation Prodromus (1669). At the same time, we will pay attention to how the set of figures would continue to be borrowed by such authors as Paolo Silvio Boccone (1674), Michael Bernhard Valentini (1704), and Gottfried Wilhelm Leibniz (1749, originally circa 1691). In the meantime, the original manuscript with figures was published in 1717 as Metallotheca Vaticana by Giovanni Maria Lancisi, the Italian anatomist and one of Steno’s acquaintances. Lancisi made annotations to this text that suggested the fossil controversy was evolving, citing the names of Cesalpino, Steno, Boccone, and Vallisneri. Thus, we can understand how the illustrations with its hidden text functioned well in the fossil controversy by the strategic usage by Steno of the Vatican collection, a sort of ‘museum on paper’.
THE DINOTHERIUM AND THE ACROPOLIS: ALBERT GAUDRY’S RECONSTRUCTION OF THE EXTINCT FAUNA OF ATTICA AND THE MAKING OF GREECE INTO A EUROPEAN STATE (1850s–1860s)
Authors: MONNIN VICTOR
Published: November 2024

Between 1862 and 1867, Albert Gaudry (1824–1908) published Animaux fossiles et géologie de l’Attique, a seminal work describing and depicting the rich collection of mammalian fossils that he assembled during his scientific expeditions in Attica, Greece. This paper will focus on how Gaudry’s collection and reconstruction of the extinct fauna of Attica articulated itself with geopolitical, cultural, and economic concerns regarding the newly independent Greek state and its place within Europe. Since the Greek War of independence against the Ottomans between the 1820s and 1830s, European nations sought to secure a series of strategic advantages in the region. France for example invested a lot of capital, military, and cultural resources in the newly independent Greek state in hope of cementing France’s influence in the Mediterranean. Between 1853 and 1854, Gaudry was sent on a mission by the French government to evaluate the agricultural production of countries of the ‘Orient’, including Greece. Gaudry was tasked with gathering information intended to facilitate the advancement of agriculture in France’s colonies as well as the planning of future investments in the Eastern Mediterranean. In his report published in 1855, Gaudry explicitly defined the restoration of Greece’s agricultural industry as a sine qua non condition for Greece’s establishment as a European state. It was during this official mission that Gaudry learned about the existence of exceptionally rich fossil sites in Attica. He returned on multiple occasions to collect thousands of fossil specimens from these sites. In Animaux fossiles et géologie de l’Attique and in his subsequent publications on the same fossils, Gaudry regularly articulated the reconstruction of extinct mammals and their environment with inspired descriptions of the ruins of Athens. In his writings, the reconstruction of a Greek geological past inhabited by a grandiose and harmonious megafauna echoed the celebration of Ancient Greece as the cradle of Western civilization. This paper will comment on the complex interplay between three temporalities which informed Gaudry’s work on the mammalian fossils of Attica: (1) the reconstructed paleontological past, (2) the idealized Ancient Greece, and (3) the present geopolitical context.
THE PINK ROCKS OF CARLO CRIVELLI (CIRCA 1489)
Authors: MONTANARI ALESSANDRO , PIGNOCCHI GAIA , MAINIERO GIANLUCA , MAINIERO MAURIZIO
Published: November 2024

Until the 1800s, art historians considered the Venetian artist Carlo Crivelli (circa 1435–1495) to be a secondary if not a minor painter. This lack of recognition stems essentially from the dissemination of his paintings in churches and convents throughout the provincial region of Marche (central-eastern Italy), where Crivelli spent the most productive period of his life from 1468 until his death in 1495. As a consequence of this limited accessibility, his paintings could not be seen by mainstream art dealers and historians such as the scrupulous Giorgio Vasari (1511–1574). More than anybody else, the British demonstrated a great interest in Crivelli’s art in the late 1800s by acquiring many of his dispersed paintings that eventually ended up in the National Gallery of London, where the richest collection of the artist’s paintings is preserved today. Among them, ‘The Vision of the Blessed Gabriele’ is the one that attracted our attention not so much for its pictorial qualities and symbolic significance typical of Renaissance paintings, but rather for the many details making up the background of the painting, which accurately depicted the geological and environmental characteristics of the Adriatic port city of Ancona and the nearby Monte Cònero mountain. In this research, besides a meticulous study of architectural, geomorphologic, faunal, and floral details, we focused on the representation of a large outcrop of strikingly pink, thinly stratified rocks, which we studied through a quantitative RGB (red, green, blue) chromatic analysis and then compared the results with those from an analogous analysis of rock samples and outcrop images of all the more-orless red formations of the Umbria-Marche lithostratigraphic succession. This led us to the conclusion that Crivelli’s pink rocks represent the lower Paleogene Scaglia Rossa limestone exposed at Monte Cònero. Thus, the background of Crivelli’s painting ‘The Vision of the Blessed Gabriele’ is no longer an idealized landscape put there as a symbolic or simple wing of a theater stage, but a realistic representation of the physical environment surrounding the main subject of the painting as only a few Renaissance maestros like Piero della Francesca, Andrea Mantegna, and Leonardo da Vinci incorporated in their most famous and studied masterpieces.
Hilkat Garibeleri: Osmanlı Toplumunda Doğum Anomalisi ile Dünyaya Gelenler
Authors: Muşmal Hüseyin , Gürbüz İrem
Published: November 2024

Günümüzde olduğu gibi Osmanlı toplumunda da doğum anomalisiyle (doğuştan gelen bedensel farklılıklarla) dünyaya gelen insanların bulunduğu bilinmektedir. Osmanlı arşivlerinde yaptığımız taramalarda bu türden rahatsızlıklara dair bazı belgeleri tespit etmek mümkün olmuştur. Konuyla ilgili belgeler, genellikle doğum anomalisiyle dünyaya gelenlerin görünümlerinin olağan dışı olarak görülmesi neticesinde bu kişilerin durumlarını anlatan çeşitli içeriklere sahiptir. Belgelerin az bir kısmı ise doğum anomalisine sahip kişilerin geçimlerini sağlayabilmeleri için maddi olarak devlet tarafından himaye edilmelerini içerir. Buradan hareketle elde edilebilen örnekler üzerinden devletin ve toplumun bu konudaki algı ve tutumlarını incelemek mümkündür. Osmanlı toplumunda bedensel farklılıkları bulunan insanlar veya hayvanlar için genellikle “Hilkat Garibesi” ifadesi kullanılmıştır. Toplum tarafından şaşkınlıkla karşılansa da bu insanların durumu hilkatten yani yaratılıştan görülmüş ve böyle yorumlanmıştır. Dolayısıyla hem kullanılan tabirler hem de onlara karşı sergilenen yaklaşımlardan hareketle Osmanlı toplumunda anormal doğumların Allah’ın varlığı ve onun kudretiyle izah edilmeye çalışıldığı söylenebilir. Bu bakış açısının temelinde Türk toplumunun kültürel değerleri ve İslam inancının bulunduğu anlaşılmaktadır.

Amerikan misyonerleri, Amerikan resmî çevrelerinin de yardımıyla Ermenilere destek olmak için temeli 1915 yılında atılan Yakın Doğu Yardım Komitesini kurmuşlardır. Komitenin sağlık hizmetlerinin yetersiz olduğu yerlerde donanımlı hastanelerde modern yöntemlerle hastaları tedavi etmeleri, insanların sevgi ve sempatilerini kazanmalarında etkili olmuştur. Komite özellikle bakıma muhtaç olan Ermeni çocukların sağlık hizmetleriyle yakından ilgilenmiştir. Bu çerçevede dönemin yaygın hastalığı olan veremle etkin mücadele için başkent İstanbul başta olmak üzere sağlık müesseseleri teşkil etmiştir. 1920 yılında kurulan ve veremli çocuklar için hizmet vermeyi amaçlayan “Yedikule (Kanada) Veremli Çocuklar Hastanesi” türünün ilk örneklerinden biri olması açısından önem arz etmektedir. Açıldığı zaman yoğun bir ilgi gören hastanede, veremle ilgili vakalar modern yöntemlerle tedavi edilmiştir. Bu çalışmada 1920-1921 yılları arasında adı geçen hastanenin kuruluş süreci, doktor ve diğer sağlık personeli, hastaneye katkısı olup yardım edenler, hastanede sürdürülen sosyal etkinlikler, tedavi edilen vakalar ve sayıları, hasta çocukların hissettikleri duygular gibi pek çok konu, Amerikan Yakın Doğu Komitesi belgeleri ışığında tarafsız bir şekilde tarih metodolojisi çerçevesinde ele alınmaya çalışılmıştır.
Daily Lifestyle Managed by Natural Disasters in Anatolia
Authors: Erler Mehmet Yavuz
Published: November 2024

The heart of Anatolia was devastated by two major droughts between 1800 and 1880. The severe winter conditions during this period, followed by subsequent floods, once again destroyed farmers' crops. The great earthquake in Bursa further burdened the already exhausted society with pain and sorrow. In this study, data will be evaluated to understand how people in Anatolia, exposed to successive disasters, had to adapt their livelihoods. The focus will be on how workshop-style collective production, which had begun to emerge in Anatolia on the brink of the Industrial Revolution, was disrupted by natural disasters, and why the agriculture-based economy remained predominant. The study includes observations on the changes in Bursa and Adana, where disaster-affected populations clustered after being displaced. The contribution of cheap labor, provided by victims of natural disasters, to the manufacturing sector in Bursa, Adana, Aydın, and Izmir is analyzed in relation to the small-scale industrial transformations in these cities. A comparison is made between the livelihoods of the local population before the disasters and their income sources afterward. Based on this comparison, the impact of disasters on livelihoods is discussed. Additionally, the types of disasters and their varying degrees of impact in Ankara and Konya are examined.

Published: November 2024

The present study reports the implementation of a didactic sequence in Spanish and English with the objective of supporting the development of social skills in a person with mild functional diversity. Based on socio-cognitive and linguistic frameworks, the didactic intervention proposed consists of classes in Spanish and English adapted to the specific context and situation of the individual. The study’s methodological strategy is based on a qualitative approach and descriptive reach, viewed from the perspective of action research and a case study design. The data is collected as follows: documentary analysis, participatory observation, initial interviews, a journal and observations, and final interviews. The results indicate that the didactic sequence develops three of the six social skills proposed by Monjas Casares (2007). The research concludes that instruction mediated by Spanish and English can help to develop the social skills of subjects with functional diversity. Also, aspects such as context and audience can cause these skills not to develop linearly or in all settings. All in all, this study indicates that social cognition, empowered by friendly and comprehensive interaction, can work as a mechanism to develop individual cognitive processes in subjects with mild functional diversity, which entails improvements in higher cognitive processes like executive functions, language, and empathy.

Oral health is a human right, an integral part of general health and essential for overall wellbeing and quality of life. Proper oral health care reduces premature mortality Nurses act as a link between admitted patients and doctors in the hospital. Public health nurses can educate people about health subjects. The study was conducted to assess oral health knowledge and attitude among nursing students and staff in Mahasamund city, India.

To assess the level of knowledge and attitude regarding oral health among nursing students and staff in Mahasamund City, India and to identify gaps that can be addressed through targeted educational interventions.

The study was conducted at five nursing colleges in Mahasamund city, India. A total of 281 nursing students and staff from nursing colleges were included and requested to complete 25 closely ended questionnaires. A written informed consent was taken. The data collected was analysed using Statistical Package for the Social Sciences 16.0 and frequencies were calculated for each item in the questionnaire.

53% were of the view that toothpaste and brush is an ideal material for brushing. More than (73%) participants responded that gum infections were responsible for bleeding from gums. Almost 6.4% reported that brushing should be done twice daily. The majority of those (65%) had sufficient knowledge for detection of Dental Caries. Almost 66% had sufficient knowledge about Public Health Dentistry. Most of the (70%) were interested in doing work at the Public Health Dentistry.

The overall oral health knowledge and attitude of nursing students and staff was insufficient.  Only half of the study participants were aware of various aspects of oral health. Nurses should have basic knowledge about oral health and disease. It is recommended that a dental curriculum should be introduced in the nurses undergraduate training program which can be housed in Public Health Dentistry department as a part of community nursing.

Published: November 2024

In the oral cavity, fibroma is the most common type of connective tissue tumor. The size of these proliferative benign connective tissue tumors varies from tiny to large, contingent upon the degree of presence of one or more components of the inflammatory response. They are usually asymptomatic.It is a locally confined hyperplasia of fibrous connective tissue brought on by persistent inflammation or local trauma. This lesion is more typically observed in men, with a preference for buccal mucosa, labial mucosa, and tongue . This lesion preferentially affects the tongue, buccal mucosa, and labial mucosa. A traumatic or irritating fibroma develops from an inflammatory hyperplastic lesion that can occur at any age and in almost any soft tissue location.

Published: November 2024

Background: Multiple sclerosis (MS) is a long-term autoimmune disorder affecting the central nervous system, leading to reduced quality of life and impaired physical and psychological functions.
Objectives: This study aims to examine the relative efficacy of yoga and relaxation therapy in improving sleep disturbances, fatigue, and cognitive impairment among individuals diagnosed with MS.
Methods: This study employed a semi-experimental research design, including a pre-test, post-test, and follow-up over three months. The target population comprised all MS patients referred to the Iranian MS Association in Tehran between July and November 2023. Sixty participants were selected using purposive sampling and randomly assigned to research groups: Two yoga therapy groups with 17 participants each, a relaxation therapy group with 16 participants, and a control group with 18 participants. The yoga therapy group participated in twelve 90-minute sessions twice a week, while the control group received no intervention and was placed on a waiting list. Various tools, including the Multidimensional Fatigue Inventory (MFI), Cohen-Mansfield Agitation Inventory (CMAI-O), and a concentration skills questionnaire, were used to collect data. The data were analyzed using ANOVA, Bonferroni post hoc test, MANCOVA, and Kruskal-Wallis H tests with a significance level of 0.05, utilizing SPSS 27 software.
Results: The study found a significant difference (P < 0.001) in the restlessness factor in both the post-test and follow-up phases. Additionally, there was a significant difference (P < 0.001) in the levels of physical fatigue, mental fatigue, decreased activity, and decreased motivation in both the post-test and follow-up phases, indicating significant changes in the fatigue factor among the research groups. However, there was no significant difference in the general fatigue component between the research groups. A significant difference (P < 0.001) was also found in the concentration factor, particularly in the components of voluntary and involuntary concentration, during both the post-test and follow-up stages.
Conclusions: The results of this study indicate that both yoga and relaxation therapy techniques significantly reduce restlessness, physical tiredness, mental fatigue, decreased activity, and decreased motivation. Furthermore, the findings validate that both yoga and relaxation therapy techniques effectively enhance voluntary and involuntary concentration.

Mathematical foundation of High-Dimensional Data Analysis: Leveraging Topology and Geometry for Enhanced Model Interpretability in AI
Authors: Keningson Jonathan
Published: November 2024

One of the most important challenges for modern AI and machine learning is the analysis of high-dimensional data. Traditional methods face serious complications in such cases due to high complexity of datasets: the curse of dimensionality, overfitting, and lack of transparency of model behavior. In this paper, we adopt a novel approach to analyze high-dimensional data; topological and geometric techniques will be exploited, taking advantage of better model interpretability and deeper insights into the structure. Precisely, we discuss Topological Data Analysis, mainly Persistent Homology  (Edelsbrunner et al., 2002), which allows the extraction of topological features-like loops and connected components that enable the extracting knowledge about the global structure of data. We also see how some concepts of differential geometry and Riemannian geometry (Do Carmo, 1976) can be used to cast light on manifold data structure lying at the heart of any attempt at modeling intrinsic patterns in high-dimensional spaces.
We will review how these mathematical pillars, combined with state-of-the-art techniques for dimensionality reduction like t-SNE, UMAP, Principal Component Analysis, are able to provide interpretable and low-dimensional representations of high-dimensional data that can be used to understand models and make decisions. Case studies are also included, which explain the practical working of these methods in AI systems and show how much complex models can be made transparent using these, especially in domains that are very critical, such as healthcare  (Caruana et al., 2015), finance (Chen et al., 2018), and autonomous systems ( Wang et al., 2019).
We also discuss some of the difficulties in using these methods for practical applications: computational complexity; the need for large-scale data processing (Bengio et al., 2007); and integration of topological and geometric intuition with the rest of the machine learning pipeline (Zhu et al., 2020). We conclude with possible future directions of research toward fine-tuning these methods and exploring their broader applicability to AI in its quest for more robust, interpretable, and reliable AI models. Given this work, we focus on how linking topology, geometry, and AI bears great promise for solving one of today's critical challenges: model interpretability in high-dimensional data analysis.

Lymphocyte-monocyte index as a new marker for the prognosis of early recurrence of the disease in patients with glioblastoma
Authors: Sklyar S. S. , Matsko M. V. , Safarov B. I. , Ulitin A. Yu. , Olyushin V. E. , Samochernykh K. А.
Published: November 2024

Every day, the number of scientific studies in the global medical community is growing, emphasizing the importance of the immune system in the prognosis and course of oncological diseases. The lymphocyte-monocyte index has already demonstrated its prognostic role in some forms of tumor disease. However, its significance in glioblastomas has not been fully determined.

The aim of the study is to study the prognostic value of the lymphocyte-monocyte index for patients with glioblastoma.

Material and methods. The study included 45 patients with primary supratentorial glioblastoma over the age of 18 who had reached the first relapse of the disease. In each case, the level of leukocytes, lymphocytes, monocytes and LMR (ratio of lymphocytes to monocytes) in peripheral blood before surgery was assessed, and symptomatic treatment with glucocorticosteroids was taken into account. The histological diagnosis was established in accordance with the WHO classification of Central nervous system tumors in 2021. All patients after the neurosurgical stage of treatment received standard antitumor treatment (radiation therapy, chemotherapy with temozolomide). The effect of LMR on the median of the first relapse-free period was studied.

Results. A significant increase in the absolute number of monocytes was found in patients receiving dexamethasone therapy (p = 0.014). At the same time, the appointment of GCS did not affect the level of lymphocytes and LMR. The median of the first relapse-free period was statistically higher in patients with an LMR of more than 4 (p = 0.05; 47 vs 30.5 weeks).

Conclusions. Low LMR is a marker of the prognosis of early recurrence of the disease for patients with glioblastomas. It is important to note that despite the fact that the level of monocytes was directly correlated with the appointment of glucocorticosteroids to patients, the LMR was not affected by the appointment of this group of drugs.

Background: New chemotherapy regimens (gemcitabine / nab-paclitaxel, FOLFIRINOX) have improved overall survival rates in ductal carcinoma, which has renewed the interest in surgical treatment for isolated liver metastases.
Aim: To identify the role of surgery in ductal carcinoma of the pancreatic head with liver oligometastases.
Methods: We retrospectively analyzed the data from 490 patients with morphologically verified ductal carcinoma of the pancreatic head in two specialized centers, who had undergone pancreatoduodenectomy (PD) from January 2011 to April 2024. In 21 patients, PD was performed simultaneously with liver resection (liver oligometastases were found during the surgery).
Results: In the postoperative period after PD with liver resection, compared to that after PD without liver resection, intra-abdominal abscesses were more frequent (4/21 (19.0%) versus 10/469 (2.2%), p = 0.002) and relaparotomy was performed more often by 9.8% [95 confidence interval (CI, Miettinen-Nurminen score method) 0.21–30.3] (3/21 (14.3%) versus 21/469 (4.5%), p = 0.077). The postoperative death rates were comparable (1/21 (4.8%) versus 19/469 (4.1%), p = 0.8). The median overall survival of the patients after PD with liver resection was 11 (95% CI: 6–16) months, and overall 1-, 2-, and 3-year survival rates were 39.2, 16.8 and 7.2%, respectively. In the patients after PD with liver resection without any adjuvant chemotherapy (n = 5), the median overall survival was 6 (95% CI: 5–7) months, and in those with chemotherapy, 13 (95% CI: 6–16) months (p = 0.006). The overall three-year survival of the patients after PD with liver resection and adjuvant chemotherapy was 11.5%. In the patients after PD with liver resection R0, the median overall survival was 13 (95% CI: 6–32) months, with R1 resection 6 (95% CI: 6–7), and with R2 resection 6 (95% CI: 6–7) months (p = 0.021). The median overall survival of patients after PD with liver resection for G1 tumors was 17 (95% CI: 6–32) months.
Conclusion: Surgery as a component of combination therapy for oligometastatic pancreatic head cancer can be considered in a certain category of patients with high tumor differentiation grade and mandatory preliminary assessment of the feasibility of R0 surgery and systemic chemotherapy.

Weeds: A Vibrant Source for Eco-dyeing
Authors: Sugina P. , Sindhu P.V.
Published: November 2024

The concept of color has consistently played a significant role in developing various human societies globally. It impacts all aspects of our lives, including the clothes we wear. As a result, the synthetic textile colouring industry has grown significantly. On the contrary, there has been a resurgence in the attention towards natural dyes due to the environmental apprehensions of synthetic dyes and their harmful health effects, as natural dyes are perceived to be more sustainable. Weeds are plants that are out of place and undesirable in a particular environment. Converting these plants into valorized products will be an efficient way of managing them. Many weeds have been identified as potential sources of natural plant pigments like anthocyanins, betalains, carotenoids, and other natural pigments. Using weed plants for dye extraction not only provides an alternative dye source but also helps to reduce weed plant invasion. A variety of natural colours can be extracted from weeds. Furthermore, several invasive species, including wire weed, siam weed, common purslane, etc., can be used to extract different hues and tints.

Methods: This study was carried out at the research farm of ICAR-Indian Institute of Farming Systems Research, Modipuram, during 2017-2021.The divergent cropping sequences viz. sugarcane-ratoon-wheat (CS1); rice-wheat-dhaincha (CS2); pigeonpea +maize-chickpea-okra (CS3); maize-berseem-black gram (CS4); sorghum-mustard-green gram (CS5) and Napier+cowpea/berseem (CS6) were compared in reference to curtail higher energy inputs through selected alternate cropping sequences. The obtained energy values were calculated by multiplying the amount of inputs and outputs by using energy conversion factors. Result: Maximum inputs energy consumed by sugarcane crop alone (33.14x103 MJ ha-1). Results shown that irrigation, seed, fertilizers and diesel required higher energy for the completion of cultural operations. However, higher inputs energy was used in irrigation followed by seed and fertilizers, respectively. In regard to per cent energy intake through inputs, the highest energy spent was for irrigation (35.30 MJ ha-1) and fertilizer (23.80 MJ ha-1).The wheat equivalent yield was higher in sugarcane-ratoon-wheat (125.58 t ha-1). Maximum output energy was with above system (596.70×103 MJ ha-1). Highest net energy returns was counted with sugarcane-ratoon-wheat (549.37x103 MJ ha-1), energy ratio (12.60) and energy profitability (11.60). Indeed, energy efficiency was highest in same system (1657.50) followed by maize-berseem-black gram (1421.96).

This research study aimed to assess the nature of science (NOS) understanding among students attending science and art centers in Türkiye. The study employed a case study design and a qualitative research method, focusing on 60 identified gifted middle school students at the Selçuklu Science and Art Center during the 2022-2023 academic year. The students' perspectives on the NOS were evaluated using the Nature of Science Evaluation Scale, and the collected data underwent descriptive analysis. The study's findings revealed that a majority of the gifted students demonstrated perspectives aligned with the NOS. However, many of these students' views regarding the role of scientists in shaping scientific knowledge did not align with the NOS. Additionally, the results indicated that students predominantly attributed the development of scientific knowledge to the observations made by scientists. These findings emphasize the significance of implementing targeted activities to enhance students' understanding of the NOS, potentially aligning their perspectives with the established principles of NOS.

La evolución de la representación de la mujer andina migrante en dos películas latinoamericanas contemporáneas
Authors:   , Capcha Ramirez Valeria Alexandra
Published: November 2024

En América Latina, la mujer ha sido relegada en su rol social a lo largo de la historia. Esta situación deficitaria se agrava cuando esa mujer es andina, y se agudiza cuando, además de andina, es migrante. Dos películas latinoamericanas contemporáneas tratan esta problemática: La teta asustada (Llosa, 2009), de la directora Claudia Llosa, y Lina de Lima (González, 2019), de la directora María Paz González. Desde ese orden de ideas, el objetivo de esta investigación es describir la evolución que ha experimentado la mujer andina migrante de una película a otra, las cuales tienen en común que el rol de la protagonista se encarna en la actriz peruana Magaly Solier. Para ello, se realizó, bajo el paradigma interpretativo, un estudio de enfoque cualitativo, diseño hermenéutico, y de alcance descriptivo. El análisis de contenido fue la técnica de recolección de datos, para lo cual se elaboró, validó y aplicó una matriz de análisis de contenido audiovisual. Los resultados más importantes arrojan que la evolución de la mujer andina migrante se explica con criterios como la maternidad, la sexualidad y el rol ocupacional. El personaje prototípico de la mujer andina de la primera película evoluciona, en la segunda, a un personaje empoderado, moderno, poseedor de agencia y dueño de su toma de decisiones. Se concluye que, por tratar una temática común y presentar a la misma actriz en el rol protagónico, las dos películas pueden interpretarse como una sola secuencia que configuraría la evolución de una mujer andina migrante en Latinoamérica.

Esta investigación analiza la traducción del lenguaje étnico-racista en los doblajes al español latinoamericano y español peninsular de BlacKkKlansman (2018) con el fin de ampliar la evidencia en torno a la traducción en contexto de los insultos racistas. Considerando el aspecto audiovisual de las películas y la barrera sociocultural e histórica entre EE. UU. y Latinoamérica y España, el método de estudio es cualitativo-contrastivo. Se compara ambos doblajes con la versión en inglés y se explica el cambio del sentido de términos y frases étnico-racistas, además de identificar el uso de técnicas de traducción y señalar el grado de dependencia al contexto sociocultural e histórico y situacional. Los resultados muestran el uso reiterativo de técnicas como la generalización, la adaptación, la traducción literal, la compresión lingüística y la descripción. Al someterse al proceso traslativo, los insultos racistas mantienen en distintos niveles el sentido ofensivo original del lenguaje étnico-racista en sus respectivos doblajes.
