The treatment of error in learners of Russian as a foreign language: Visual analytics
Authors: González-Hidalgo Inés de los Ángeles , Barros García Benamí , Arroyo-Machado Wenceslao
Published: March 2024

There are well-known challenges in the assessment of learning in general, and especially in foreign language learning. The treatment of error in the classroom is a recent topic of research and one that has given rise to multiple approaches to pinpoint, identify and classify the errors made by learners of foreign and second languages. This article presents a methodological model based on visual analytics and education data mining to optimise teacher intervention in the face of individual and collective errors in the Russian language classroom. The methodology has been tested on learners of Russian as a foreign language at the University of Granada. It comprised an online questionnaire for skills assessment, with 75 questions that were classified by grammatical category and sub-category. It was filled out by the learners of the 2021/2022 academic year, yielding 31 responses. The responses were then analysed through visual analytics and education data mining techniques. Clustering questions and learners allowed the identification of different error patterns and groups of learners with common errors. This serves to demonstrate the usefulness of these techniques for classroom assessment.
Multilingual Crowdsourcing Motivation on Global Social Media. Case Study: TED OTP
Authors: Cámara de la Fuente Lidia
Published: March 2024

Crowdsourcing has emerged in recent year as a new form of volunteering activity. The distributed nature of online volunteers enabled global organizations to mobilize talents from around the world. In this spirit, the past decade has witnessed a vibrant expansion of intercultural virtual collaborative efforts within the crowdsourced audiovisual translation communities. The aim of our work is to characterise key motivational factors driving volunteer translators to engage in these intercultural collaboration endeavours within one of those virtual communities. As a case in point, I will study TED[1], a global communication platform where people from all over the world interact with each other creating, sharing, exchanging and commenting on content within a virtual community and several networks. At TED unpaid volunteers translate audiovisual content into 100 languages, within the framework of an online translation project: the Open Translation Project, hereinafter referred to as OTP. I asked a group of 177 OTP participants who range across 35 different languages and are geographically distributed over four continents, to pinpoint key motivation factors for becoming volunteer translators.  [1] TED stands for Technology, Entertainment and Design
The Mechanism of Polygonum Hydropiper L-Coptis Chinensis in the Treatment of Ulcerative Colitis Based on Network Pharmacology and Experimental Validation
Authors: Zhu Feifei , Zhi Yunyun , Li Yonghui , Niu Haiyan , Ren Shouzhong
Published: March 2024

Background: Polygonum hydropiper L (PH) was widely used to treat dysentery, gastroenteritis, diarrhea and other diseases. Coptis chinensis (CC) had the effects of clearing dampness-heat, purging fire, and detoxifying. Study confirmed that flavonoids in PH and alkaloids in CC alleviated inflammation to inhibit the development of intestinal inflammation. However, how PH-CC affects UC was unclear. Therefore, the aim of this study is to analyze the mechanism of PH-CC on ulcerative colitis (UC) through network pharmacology and in vivo experiments. Methods: The active ingredients and targets of PH-CC and targets of UC were screened based on related databases. The core targets of PH-CC on UC was predicted by protein-protein interaction network (PPI), and then the Gene Ontology-biological processes (GO-BP) function enrichment analysis was conducted using the Database for Annotation, Visualization and Integrated Discovery (DAVID) database. The binding activity between pyroptosis proteins, core targets and effective ingredients were verified based on molecular docking technology. Finally, combined with the results of network pharmacology and literature research, the mechanism of PH-CC against UC was verified by in vivo experiments. Results: There were 23 active components and 191 potential targets in PH-CC, 5275 targets in UC, and 141 co-targets. GO-BP functional analysis of 141 co-targets showed that the first 20 biological processes were closely related to inflammation and lipopolysaccharide (LPS) stimulation. Furthermore, core targets had good binding activity with the corresponding compounds. Animal experiment indicated that PH-CC effectively prevented weight loss in UC mice, reduced the disease activity index (DAI) score, maintained colon length, suppressed myeloperoxidase (MPO) activity, inhibited pyroptosis protein expression, and downregulated the levels of IL-18 and IL-1β to alleviate intestinal inflammation. Conclusions: The results of network pharmacology and animal experiments showed that PH-CC suppressed the inflammatory response, restored colon morphology, and inhibited pyroptosis in UC mice. Thus, PH-CC may improve UC by regulating the NOD-like receptor protein domain 3 (NLRP3)/Caspase-1 signaling pathway.

Authors: Tan Yahang , Liu Chang , Chen Tao , Li Yina , Wang Chengjian , Zhao Jia , Zhou Jia
Published: March 2024

Background: For individuals with persistent stable chest pain (SCP) and a coronary artery calcium score (CACS) of 0, it might be challenging to establish the best risk assessment method for determining the individuals who will not benefit from further cardiovascular imaging testing (CIT). Thus, we investigated the CACS-weighted clinical likelihood (CACS-CL) model in SCP patients with a CACS of 0. Methods: Thus, to assess SCP, we originally enrolled 14,232 individuals for CACS and coronary computed tomography angiography (CCTA) scans between January 2016 and January 2018. Finally, patients with a CACS of 0 were included and followed up ​until January 2022. According to the established CACS-CL cutoffs of 15% and 5%, the associations between coronary artery disease (CAD) and major adverse cardiovascular events (MACEs) in risk groups were evaluated, alongside the net reclassification improvement (NRI). Results: Of the 6689 patients with a CACS of 0, the prevalence of CAD increased significantly (p < 0.0001) in patients with higher CACS-CL. However, there was no significant difference in the CAD distribution (p = 0.0637) between patients with CACS-CL <5% and 5–15%. The association between the CACS-CL = 15%-determined risk groups and the occurrence of MACEs was stronger than for a CACS-CL = 5% (adjusted hazard ratio (HR): 7.24 (95% CI: 1.93–16.42) versus 3.68 (95% CI: 1.50–8.26)). Compared with the cutoff for CACS-CL = 5%, the NRI was 10.61% when using a cutoff for CACS-CL = 15%. Conclusions: Among patients with an SCP and CACS of 0, the CACS-CL model provided accurate predictions of CAD and MACEs. Compared to the cutoff for CACS-CL = 5%, the cutoff for CACS-CL = 15% seemed to be more effective and safer for deferring further CIT. Clinical Trial registration: NCT04691037.

Published: March 2024

Background: Identifying effective pharmacological interventions to prevent the progressive enlargement and rupture of aortic aneurysms (AAs) is critical. Previous studies have suggested links between metformin use and a decreased incidence of AAs. In this study, we employed Mendelian randomization (MR) to investigate causal effects of metformin’s targets on AA risk and to explore the underlying mechanisms underlying these effects. Methods: To examine the relationship between metformin use and AA risk, we implemented both two-sample MR and multivariable MR analyses. Utilizing genetic instrumental variables, we retrieved cis-expression quantitative trait loci (cis-eQTL) data for potential targets of metformin from the Expression Quantitative Trait Loci Genetics Consortium (eQTLGen) Consortium and Genotype-Tissue Expression (GTEx) project. Colocalization analysis was employed to ascertain the probability of shared causal genetic variants between single nucleotide polymorphisms (SNPs) associated with eQTLs and AA. Results: Our findings reveal that metformin use reduces AA risk, exhibiting a protective effect with an odds ratio (OR) of 4.88 × 10-3 (95% confidence interval [CI]: 7.30 × 10-5–0.33, p = 0.01). Furthermore, the protective effect of type 2 diabetes on AA risk appears to be driven by metformin use (ORMVMR = 1.34 × 10-4, 95% CI: 3.97 × 10-8–0.45, p = 0.03). Significant Mendelian randomization (MR) results were observed for the expression of two metformin-related genes in the bloodstream: NADH:ubiquinone oxidoreductase subunit A6 (NDUFA6) and cytochrome b5 type B (CYB5B), across two independent datasets (ORCYB5B = 1.35, 95% CI: 1.20–1.51, p = 2.41 × 10-7; ORNDUFA6 = 1.12; 95% CI: 1.07–1.17, p = 1.69 × 10-6). The MR analysis of tissue-specific expression also demonstrated a positive correlation between increased NDUFA6 expression and heightened AA risk. Lastly, NDUFA6 exhibited evidence of colocalization with AA. Conclusions: Our study suggests that metformin may play a significant role in lowering the risk of AA. This protective effect could potentially be linked to the mitigation of mitochondrial and immune dysfunction. Overall, NDUFA6 has emerged as a potential mechanism through which metformin intervention may confer AA protection.

Published: March 2024

Infective endocarditis (IE) is a life-threating entity with three main complications: heart failure (HF), uncontrolled infection (UI) and embolic events (EEs). HF and UI are the main indications of cardiac surgery and have been studied thoroughly. On the other hand, much more uncertainty surrounds EEs, which have an abrupt and somewhat unpredictable behaviour. EEs in the setting of IE have unique characteristics that must be explored, such as the potential of hemorrhagic transformation of stroke. Accurately predicting which patients will suffer EEs seems to be pivotal to achieve an optimal management of the disease, but this complex process is still not completely understood. The indication of cardiac surgery in order to prevent EEs in the absence of HF or UI is in question as scientific evidence is controversial and mainly of a retrospective nature. This revision addresses these topics and try to summarize the evidence and recommendations about them.

Relevance: Crystalloscopy - a method for diagnosing biological fluids (BF) allows you to evaluate the physical properties of BF crystals after dehydration, as well as indirectly determine the state of the BF proteome. Crystallography helps to identify pathological processes (inflammation, oncogenesis, trauma) in the body and further monitor the effectiveness of treatment. A defect in the HAD enzyme leads to a sharp decrease in ketogenesis, the accumulation of long-chain fatty acids, an increase in the formation of dicarboxylic acids that negatively affect the tissues of the brain, heart and liver, and inhibition of a number of enzymes (in particular, gluconeogenesis enzymes). Objective: to conduct a comparative analysis of the results of crystalloscopic examination of biological fluids in normal and metabolic pathology. Materials. Materials and methods: Crystalloscopic examination of saliva of 20 people and urine of 7 examined children without a verified diagnosis associated with metabolic pathology and a child with an established pathology of enzyme systems with liver damage. For a detailed analysis of the results of the study, the case history of child B., 10 months old, hospitalized at the Institute of Pediatrics of the University Clinic of the Volga Research Medical University in 2022, was considered. Discussion: The crystallogenic activity of the biological fluids of a patient with congenital liver enzymopathy is significantly transformed. In dried micropreparations of urine, a moderate increase in the crystal-forming ability of the biomedium was recorded, as indicated by an increase in the level of crystallization and structural index. A sharp increase in the degree of destruction of crystalline structures in the facies testified to the pathological nature of the changes. Also, pronounced shifts in the crystallogenic properties were revealed in the crystallograms of the patient’s blood serum according to the activation of dehydration structurization of the blood serum, as indicated by an increase in crystallization and structure index. Similar to urine samples, a sharp increase in the degree of facies destruction was recorded in this biological fluid compared to samples from healthy children. Conclusions: The method of crystalloscopic examination of biological fluids has the potential in the diagnosis of congenital and acquired persistent metabolic disorders due to the information content and simplicity and cost-effective study within the framework of medical examination.

The article discusses a clinical case of a combination of achalasia of the cardia complicated by candidal esophagitis, which led to severe dysphagia and a significant decrease in body weight of a patient suffering from hereditary motor and sensory neuropathy - Charcot-Marie-Tooth disease (CMT) type 4 E. The authors highlight the pathogenesis and clinical picture diseases, features of the course of achalasia in a patient with a hereditary neurological disease. In this clinical case, an example of a disease in a 12-year-old girl is considered. A feature of this patient was progressive dysphagia, which ultimately led to the almost complete impossibility of normal food intake and the development of nutritional insufficiency. CMT disease is a heterogeneous group of hereditary disorders affecting the peripheral nervous system, as a result of the progression of the disease, motor and sensory dysfunction develops, such patients are under the supervision of neurologists. The presence of atypical symptoms, including not only progressive muscle weakness and exhaustion, with sensory deficits in the distal parts of the limbs, but also the severity of dysphagia, which from episodic becomes permanent, prevents the passage of not only solid food, but also liquid through the esophagus, the occurrence of esophageal vomiting - should serve as the basis for a complete examination of the patient using methods that allow visualization of the esophagus. In the available domestic literature, no description of the combined course of the pathological conditions indicated in the observation was found; isolated cases are given in the foreign literature, so the description of this clinical observation is relevant for raising awareness and early diagnosis of gastrointestinal smooth muscle dysfunction against the background of polyneuropathy.

Relevance. The influence of the gut microbiota on the development of various diseases is of great interest to researchers. The conducted studies showed that in patients with chronic liver diseases, the dominant taxa of the gut microbiota were Bifidobacterium longum, Bifidobacterium adolescentis, Blautia massiliensis, and in healthy children - Neisseria flavescens. There is no comparative analysis of data on the taxonomic diversity of the intestinal microbiota in autoimmune and non-autoimmune liver diseases in children. Purpose of the study. To investigate differences in the taxonomic diversity of fecal microbiota in patients with autoimmune and non-autoimmune liver diseases, as well as to evaluate potential biomarkers of 16S rRNA gene amplicons in these diseases by comparing the taxonomic composition. Scope and methods of research. A metagenomic analysis of the intestinal microbiota of 24 children with chronic liver diseases (mean age 10.3±4.7 years) was carried out with the identification of the V3-V4 region of the 16S rRNA gene. The group included 18 children with autoimmune liver diseases and 6 children with non-autoimmune liver diseases. Research results. The conducted study revealed 684 types of microorganisms in the studied samples of patients’ faeces. The analysis of the conducted studies showed that no dominant taxa were found in the faecal samples of children with autoimmune liver diseases, while Veillonella dispar, Veillonella parvula, Cloacibacillus porcorum, Prevotella histicola and Bacteroides eggerthii were the dominant taxa in patients with non-autoimmune liver diseases. Conclusion. Studies have shown differences in the composition of the gut microbiota in children with autoimmune and non-autoimmune liver diseases.

Evaluation and Improvement of Power System Security with the Application of Machine Learning
Authors: P Venkatesh , N Dr Visali
Published: March 2024

The electricity grid has added many renewable and non-renewable energy sources to meet expanding demand. Sudden load variations exacerbate generator, transmission line, and distribution network issues. Load modelling choices are crucial for system prediction. This study indicates that ZIP load models with contingency criteria can accurately forecast load behaviour over time. The NR method predicts the contingency ranking with the High Bride Line Stability Ranking Index (HLSRI) under single line outage conditions, and an artificial neural network (ANN) is trained to predict the severity of the line outage and the system's behaviour. A mathematical model was utilised to analyse stability and cost with and without the UPFC and IPFC. Machine learning (ML) is used to rapidly predict the most affected transmission line during a contingency by clustering data using the J48 algorithm for the location of compensating devices. The PSO algorithm is used to develop an objective function to minimise fuel costs by maximising generating capacity. A transmission line failure and load variation might damage the electrical system. This study prioritises transmission line breakdowns and load changes. Power system security analysis provides power system status.
Aesthetic Values in the Myroslav Skoryk’s Creativity
Authors: Andrushchenko Tetiana , Fedorenko Mykola
Published: March 2024

The ideological sources and origins of the issues of values in European culture at the beginning of the 20th century became the basis of this study. It is noted that the challenges regarding the specifics of the existence of value orientations were raised by neo-Kantian philosophers, in particular by Heinrich Rickert. Attention is focused on the priority role of art and music in the formation of artistic values, as well as on their aesthetic, ethical, psychological, pedagogical influence and on the creation of the ground for artistic dialogues in cultural life. The idea of value as a form of affirmation of human nature is substantiated in terms of the fundamental basis necessary for universal human culture. The content and functions, which include general cultural values: truth, beauty, good, as well as aesthetic: catharsis, kalokagathia, aura, based on the achievements of European musical art, are revealed by the author in the context of personal creativity. It is indicated that value relations are always emotional, connected with feelings of direct joyous delight, surprise; values always have a certain sacred mode, act as a shrine. It is emphasized that art in general and musical art in particular are closely related to moral and ethical guidelines, with the understanding that the concept of love in the structure of an aesthetic relationship acts as its concretization. Using the example of one of the earliest works of the composer Myroslav Skoryk (the cantata "Spring" based on a poem by Ivan Franko), it is demonstrated that the artistic material is imbued with a sensitive, joyful and loving perception of the surrounding nature; an open, trusting attitude to the surrounding world, which is generally a characteristic feature of art, especially modern art. The article examines the creative heritage of the Ukrainian artist as a carrier of valuable expression of Ukrainian culture, its intertextual, avant-garde character. It is proved that in the works of M. Skoryk, national values are organically combined with universal values.
НОВІТНІ ДОСЛІДЖЕННЯ КУРГАННОГО НЕКРОПОЛЯ ЧЕРНІГОВА ДОБИ РУСІ
Authors: Шугалій Олександр Сергійович
Published: March 2024

Протягом останнього десятиліття на території, яку займав Чернігів за доби Русі, була проведена значна кількість археологічних досліджень. Одним із результатів цих робіт стало виявлення двох десятків поховань, які можна інтерпретувати як підкурганні. Метою публікації є висвітлення нововиявлених могильних комплексів, їх датування та територіальна локалізація стосовно уже відомих частин могильника Чернігова Х−ХІ ст. Методологічною основою дослідження є принципи історизму та об’єктивності. Використані методи аналізу, синтезу, індукції. Наукова новизна публікації полягає у систематизації та локалізації нововиявлених підкурганних поховань та характеристиці комплексів стосовно території, на якій вони розміщувалися. Також необхідність даної публікації зумовлена тим, що останній раз нововиявлені підкурганні поховання були окремим предметом дослідження в науковій роботі ще на початку ХХІ ст. й існувала потреба висвітлення нових об’єктів. Висновки. Виявлені протягом 2013−2022 рр. підкурганні поховання, розташовані на території літописного Передгороддя та поза його межами, здебільшого відтворюють притаманний місцевому населенню синкретизм язичницького та християнського обрядів. Насипи в межах міста були знищені в процесі освоєння території протягом кінця ХІ−ХІІ ст., що негативно відобразилося на збереженості комплексів. У третині випадків рештки кургану фіксувалися лише за наявністю ровиків, а сама могила не була простежена. Особи, котрі поховані в малих та середніх за своїми розмірами курганах, що були виявлені протягом вказаного періоду часу, не належали до правлячої верхівки. Лише дві могили можна асоціювати з воїнами, а більша частина інвентарних поховань інтерпретуються як жіночі. Загалом же аналіз нововиявлених могильних комплексів допоміг розширити уявлення про топографію та час формування курганного могильника Чернігова.

Worldwide, one in eight deaths is due to cancer. Projections based on the GLOBOCAN 2012 estimates predict a substantive increase new cancer cases per year by 2035 in developing countries if preventive measures are not widely applied. According to the World Health Organization (WHO), millions of lives could be saved each year if countries made use of existing knowledge and the best cost-effective methods to prevent and treat cancer. Therefore, the aim of this study is to estimate a provisional budget against cancer in low and middle incomes countries, according the GNI-PPP, the cancer incidence and the number of population. Economically country classification is determining with the Gross national income (GNI), per capita, Purchasing power parity (PPP), according the administrations of the International Monetary Fund (IMF), the World Bank (WB) and the Central Intelligence Agency (CIA). Cancer incidence data presented are based on the most recent data available at IARC. However, population compares estimates from the US Bureau of the Census. The provisional budget is establishing among the guidelines developed by WHO for regional and national cancer control programs according to national economic development. Provisional budget against cancer is estimated to 248,987.936 (thousands of U.S $) for a population of 37,345,935 persons in Sudan.

Published: March 2024

A stroke is a condition because of something blocking blood supply to part of the brain or when a blood vessel in the brain bursts disrupting the blood supply to a particular portion of the brain. In either case, parts of the brain become damaged or die, manifesting as lasting brain damage, long-term disability, or even death. Symptoms include dizziness, numbness, weakness on one side of the body, and problems with talking, writing, or understanding language.

TEO, SOLO & Co. – Was und wie Taxonomien zum kompetenzorientierten Lehren und Lernen beitragen können
Authors: Brandl Werner
Published: March 2024

Taxonomien mit evident kognitivem Fokus – als hierarchisch strukturierte Kategorisierungen von Lernzielen, z. B. Taxonomy of Educational Objectives (TEO) bzw. von Learning Outcomes, z.B. Structure of the Observed Learning Outcome (SOLO) – wird mit Bezug auf die Kompetenzorientierung ein etwas defizitärer Status zugeschrieben, geradezu apodiktisch: Wissen ist keine Kompetenz! Für die demgegenüber vehement geforderte Kompetenz als Trias von Wissen, Fertigkeiten und Einstellungen gilt wohl ebenso: Ohne Wissen gibt es keine Kompetenz! Eine informative Tour d'Horizon in einer kompakten Übersicht.

A Strong Gram Classification of Non-negative Unit Forms of Dynkin Type 𝔸r
Authors: Jiménez González Jesús Arturo
Published: March 2024

An integral quadratic form q : ℤ n → ℤ is usually identified with a bilinear form [Formula: see text] satisfying [Formula: see text] for any vector x in ℤ n, and such that its Gram matrix with respect to the canonical basis of ℤ n is upper triangular. Two integral quadratic forms are called strongly (resp. weakly) Gram congruent if their corresponding upper triangular bilinear forms (resp. their symmetrizations) are equivalent. If q is unitary, such upper triangular bilinear form is unimodular, and one considers the associated Coxeter transformation and its characteristic polynomial, the so-called Coxeter polynomial of q with this identification. Two strongly Gram congruent quadratic unit forms are weakly Gram congruent and have the same Coxeter polynomial.

Here we show that the converse of this statement holds for the connected non-negative case of Dynkin type 𝔸 r ( r ≥ 1) and arbitrary corank, and use this characterization to complete a combinatorial classification of such quadratic forms started in [Fundamenta Informaticae 184(1):49–82, 2021] and [Fundamenta Informaticae 185(3):221–246, 2022].

The Electromagnetic Damping Generator (EDG) used for petroleum exploration is faced with the problem of high local temperature during its downhole work. To avoid the damage to its internal circuit caused by high temperature, the key EDG circuit is required to be heat-resistant based on the electromagnetic induction principle and the current heating effect. First of all, the working condition with the maximum heating power was figured out after studying the heating power characteristics of EDG. Then the multi-field coupling model of the temperature field, electromagnetic field and structure of the damper, as well as its iterative analytic model were established to identify the relationship between the temperature rise of the key location of the damper part and its working time in the downhole environment and the room-temperature experimental environment, which provided data support for EDG optimization design. Finally, a EDG prototype was developed, and the test bench was set up by replacing the load with resistors to verify the accuracy of the iterative analytical model. The results showed that the temperature value calculated by the model well fit the experimental value. Therefore, the downhole operation reliability of the EDG and the safety of corresponding bench tests are guaranteed, which has certain guiding significance for EDG optimization design and its experimental study.
Finite-time disturbance observer-based levitation control for vehicle-guideway coupling systems
Authors: Ren Qiao , Zhang Jimin , Zhou Hechao
Published: March 2024

In this study, a novel composite control scheme for the vehicle-guideway coupling systems is proposed, consisting of FTDOs and a FTC, aiming to address the challenges of unknown disturbances and vibration suppression. Specifically, this method adopts a single magnet-track coupling model and introduces a finite-time disturbance observer (FTDO) that utilizes only measured electromagnet-side signals to estimate unmeasurable states and unknown disturbances. Based on the estimated information provided by the FTDO, a finite-time control (FTC) scheme is developed, which simultaneously handles the problems of disturbance compensation and finite-time tracking control. Additionally, the finite-time stability of the levitation system is analyzed and proven. Finally, simulation and experimental results are given to demonstrate the feasibility and superiority of the proposed control approach.

Published: March 2024

As far as mobile edge computing is concerned, it is necessary to ensure the data integrity of latency-sensitive applications during the process of computing. While certain research programs have demonstrated efficacy, challenges persist, including the inefficient utilization of computing resources, network backhaul issues, and the occurrence of false-negative detections. To solve these problems, an integrity protection scheme is proposed in this paper on the basis of data right confirmation (DRC). Under this scheme, a two-layer consensus algorithm is developed. The outer algorithm is applied to establish a data authorization mechanism by marking the original data source to avoid the false negative results caused by network attacks from the data source. In addition, blockchain-based mobile edge computing (BMEC) technology is applied to enable data sharing in the context of mobile edge computing while minimizing the network backhaul of edge computing. Based on the Merkle Tree algorithm, the inner layer algorithm is capable not only of accurately locating and promptly repairing damaged data but also of verifying all servers in the mobile edge computing network either regularly or on demand. Finally, our proposal is evaluated against two existing research schemes. The experimental results show that our proposed scheme is not only effective in ensuring data integrity in mobile edge computing, but it is also capable of achieving better performance.

The diet of the Colares whiptail stingray, Dasyatis colarensis , was studied from 47 specimens caught off the Colares Island region, Pará (Brazil). The rays were collected in 2006 and stomach contents were analyzed qualitatively and quantitatively. Stomach repletion and item digestion levels were observed. The percentage frequency of occurrence (%F.O.), percentage by number (%N) and by weight (%W), Index of Relative Importance (IRI) and respective percentage (%IRI) were calculated for each item group. The results indicated that most stomachs (87%) were ¼ filled with food content and that most food items (59%) were highly digested. Crustaceans were the predominant food item (%IRI = 58) and included species belonging to the Portunidae (crabs), Alpheidae, Penaeidae e Palaemonidae (shrimps) families. Teleosts had an intermediate level of importance (%IRI = 42) in the diet of this species and corresponded to gobiid (Perciformes) species. Annelids and molluscs were rare food items. The results evidenced that this species feeds mainly on crustaceans, but also on fish and occasionally on other food items. The diet ofD. colarensis was similar to other Dasyatidae species.
