Ice Roughness Estimation via Remotely Piloted Aircraft and Photogrammetry
Authors: Ehrman James , Clark Shawn , Wall Alexander
Published: March 2021

Abstract. Structure-from-Motion Photogrammetry conducted with images obtained via Remotely Piloted Aircraft (RPA) has revolutionized the field of land surface monitoring. RPA-Photogrammetry can quickly and easily capture a full 3D representation of a study area. The result of this process is a high-definition Digital Elevation Model (DEM) representing the land surface of a given study area. It is particularly useful in applications where land surface data collection would otherwise be expensive or dangerous. The monitoring of fluvial ice covers can be time-intensive, dangerous, and costly, if detailed data are required. Fluvial ice roughness is a sensitive parameter in hydraulic models and is incredibly difficult to measure directly using traditional field methods. This research hypothesized that the surface roughness of a newly-frozen fluvial ice cover is indicative of subsurface roughness. The hypothesis was tested through a comparison of ice roughness determined through the statistical analysis of RPA-photogrammetry DEMs to ice roughness values predicted by the Nezhikhovskiy equation. The Nezhikhovskiy equation is a widely used empirical method for estimating ice roughness based on observed ice thickness. Hydraulic and topographic data were collected over two years of field research on the Dauphin River in Manitoba, Canada. Various statistical metrics were used to represent the roughness of the DEMs. Strong trends were identified in the comparison of ice cover roughness values determined through RPA-photogrammetry and those calculated via the Nezhikhovskiy equation, as well as with ice thickness. The inter-quartile range of observed roughness heights was determined to be the most representative roughness metric. The maximum peak value performed better in some cases, but the fact that this metric would be heavily influenced by outliers led to it being rejected as a representative metric. Three distinct forms of surface ice roughness were noted: rough, smooth, and ridged. Statistical properties of the DEMs of fluvial ice covers were calculated. No DEMs were found to be normally distributed. k-means clustering analysis was used to group sampled data into two categories, which were interpreted as rough and smooth ice. The inter-quartile range of the smooth and rough categories were found to be 0.01–0.05 meters and 0.07–0.12 meters, respectively. RPA-photogrammetry was concluded to be a suitable method for the monitoring of fluvial ice covers. Other applications of RPA-photogrammetry for the characterization of fluvial ice covers are proposed.

Down syndrome (DS) has the highest prevalence of any chromosomal abnormality identified in newborns. DS children have specific eating and swallowing difficulties such as poor tongue control, mouth opening, swallowing food without chewing, and both facial and occlusal abnormalities. DS children are also at high risk of aspiration, and swallowing food without chewing is considered to be a factor associated with increased risk of aspiration and eating problems. This study aimed to identify factors preventing the acquisition of masticatory function in DS children. The subjects were 75 outpatient DS children (44 males, age range 12 to 36 month-old, mean age 33.0 ± 7.0 month-old; 31 females, age 12 to 36 month-old, mean age 20.8 ± 8.0 month-old), who had not yet acquired masticatory function, out of 319 who visited the clinic between October 2012 and October 2017. The information necessary for assessment was retrospectively extracted from the medical records of the subjects. The items examined included age, birth weight, nutritional intake, picky eating, tactile hyperesthesia, cognitive development assessed by Ohta stage, gross motor function, occlusal condition by Hellman’s dental age, and tongue thrust/lip closure/mastication while eating. The relationships between the acquisition of masticatory function and these items were investigated after one year of rehabilitation. The revealed age, low birth weight, picky eating, and gross motor function to be relevant factors. Among these, gross motor function was found to be the factor most strongly associated with acquisition of masticatory function.

Football, une entrée remarquable dans les musées:le cas français, de 2010 à nos jours
Authors: Boli Claude
Published: March 2021

Exposer comment le football est-il entré dans les musées et comment peut-il inspirer la muséographie du XXIème siècle, telles sont les ambitions de cet article principalement focalisé sur le cas français. En France, depuis les années 2010, le football fait une entrée remarquable dans les musées. Longtemps considéré comme un sujet futile, et marqué par son rapprochement avec les goûts des milieux populaires, il a été mis hors-jeu des « salons muséaux ». A présent, le football est élevé en sujet d’excellence pour appréhender les facettes des sociétés contemporaines. La reconnaissance fut longue. Et pourtant il y avait matière à déceler dans le jeu, un signe palpable de la modernité. Les artistes, de Pablo Picasso à Adel Abdessemed, ont très vite vu dans le football, l’expression d’un monde en mutation. Ils ont pointé les enjeux du football. Lors d’événements d’envergure internationale et hautement médiatisés tels que l’Euro football ou la Coupe du monde, les musées accueillent le football. L’initiative est citoyenne, politique et économique. Une autre façon d’aborder un sujet de société s’installe progressivement dans les musées. Les travaux de l’ethnologue Christian Bromberger sont convoqués et contribuent activement à la légitimation du sujet footballistique. Incarner, mondialiser, déviriliser et décloisonner constituent les chemins à défricher pour explorer les nouveaux terrains d’une muséographie en phase avec les enjeux d’une nouvelle ère.

Authors: Cunha Cinthia da Silva , Cerávolo Suely Moraes
Published: March 2021

A cultura visual articulada ao modo-exposição expandiu-se em eventos nacionais e regionais no Brasil, influenciados pelas exposições internacionais ocorridas desde meados do século XIX. Com foco na Bahia durante o período da Primeira República, analisamos a participação desse estado federativo nas mostras comemorativas realizadas no Rio de Janeiro em 1908 (Abertura dos Portos do Brasil), em 1922 (Independência do Brasil) e na cidade do Salvador em 1923, salientando a intitulada Exposição da Verdadeira Emancipação. Esta exposição comemorava simultaneamente o centenário da independência do país e o Dois de Julho, significativa data cívica para os baianos que celebram as batalhas ocorridas na Bahia em 1823 para firmar a autonomia do país em relação a Portugal. No contexto do país sob um processo de modernização, a mostra de produtos na exposição regional operava como contrapartida para as crises internas e o paradoxal desenvolvimento visando outro patamar de civilização.

वैदिक काल में स्त्रियों को भी पुरूषों की भांति ही शिक्षा की सुविधाएं और अवसर उपलब्ध थे।अथर्ववेद में स्पष्ट ही कन्या के द्वारा ब्रह्यचर्य की व्यवस्था के पालन का उल्लेख है।मनु और कुछ बाद के स्मृतिकारो से भी मालूम होता है कि पूर्वकाल मे लड़कियों का भी उपनयन संस्कार होता था।प्रायः कन्या के विवाह की आयु 16 या 17 थी, इसलिए उन्हें शिक्षा प्राप्त करने का समय मिलता था।कुछ लड़कियां विवाह की आयु हो जाने पर भी अध्ययन समाप्त नही करती थीं,उन्हें ‘ब्रम्हवादिनी’ कहते थे । ऐसी स्त्रिया जो अध्यापन का कार्य करती थीं,उनके लिए ‘आचार्य’/‘उपाध्याया’ आदरसूचक शब्द का प्रयोग होता था। ‘औदमेघाः’ शब्द पर पतंजलि की व्याख्या से स्पष्ट है कि छात्र शिक्षिकाओं के उपयोग के लिए बने आवास ‘छात्रीषाला’ कहलाते थे। स्त्रियों को वैदिक साहित्य के अध्ययन और यज्ञों को करने का अधिकार था।

An assessment of potential groundwater recharge zones in Bulgaria
Authors: Vasileva Tanya
Published: March 2021

Groundwater resources on the territory of Bulgaria are unevenly distributed in both spatial and temporal aspects. The effective usage of these valuable assets is of paramount importance, since any over-exploitation would eventually lead to their depletion. Remote sensing data and satellite images have increasingly been used in groundwater exploration and management. An integrated approach was applied in the present study in order to delineate potential groundwater recharge zones on the territory of Bulgaria. Data from various sources were used to prepare different thematic layers. These layers were then transformed into raster data of 1×1 km. Lineament and drainage density maps of the research area were made with the help of GIS technology. In addition, a map was made for the annual total precipitation for the period from 1931 to 1985. DEM (Digital Elevation Model) data on a global scale at 90 m horizontal resolution were used for the slope analysis. A groundwater potential map was produced, which integrates several thematic maps, such as annual rainfall, geology, lineament density, land use, slope, soils, and drainage density. The thematic maps were then converted into a raster graphic format in order to be easily integrated into a GIS platform. The raster maps of these factors were then allocated a fixed score and weight-computed. The weights of those factors contributing to the groundwater recharge were derived by using the following components: geological map, lineament-length density map, land cover data base, soil data base, drainage-length density map, and slope gradient map. Subjective weights were assigned to the respective thematic layers, and they were overlaid in a GIS platform for the identification of potential groundwater recharge zones within the study area. These potential recharge zones were then categorized as being very good, good, moderate, poor, and very poor.
Привласнення фемінізму: ґендер, мілітаризм і Резолюція ООН 1325
Authors: Нікоґосян Анна
Published: March 2021

Резолюцію 1325 Ради Безпеки ООН часто називають поворотною і революційною подією. У цій статті я стверджую, що, хоч Резолюція й має революційний потенціал, вона розвивалась у ґендерованому дискурсі, який дозволив використати її в мілітаристських цілях. Спираючись на постструктуралістську феміністичну теорію міжнародних зв’язків, я розглядаю Резолюцію як дискурсивну практику та стверджую, що спосіб, у який ООН сприймає й інтерпретує концепт ґендеру і безпеки, дозволяє державам привласнювати радикальні смисли Резолюції, легітимувати й нормалізувати мілітаристські практики та замовчувати антимілітаристську критику. Аби показати це, я досліджую ґендерні дискурси, на основі яких постала Резолюція, й аналізую два основні шляхи її мілітаризації (разом із сучасними процесами мілітаризації в Республіці Вірменія).

FOUND: A DEFINITION OF INTELLIGENCE
Authors:   Lagos State University, Falode Adewunmi
Published: March 2021

Intelligence has come to play a pivotal role in the affairs of states and non-state actors in the 21st century. It not only determines the outcome of conflict when it breaks out but also provides critical edge and foresight in military planning and engagements. However, the effective utilization and deployment of intelligence in any strategic environment may be hampered by the lack of a holistic and generally accepted definition of it. The search for a robust definition has not also been helped by the differing views on what should constitute the basic elements of it. To overcome these challenges, this work argues for and provides a holistic definition of intelligence. It uses both qualitative and quantitative methodologies to provide a more robust and holistic definition of intelligence. The work concludes that any acceptable definition of intelligence must contain five key elements: process, data, actionable information, political group and security.
ENSURING INFORMATION SECURITY IN PUBLIC ORGANIZATIONS IN THE REPUBLIC OF MOLDOVA THROUGH THE ISO 27001 STANDARD
Authors:   Technical University of Moldova, Alexei Arina
Published: March 2021

. Data protection in public organizations in the Republic of Moldova (RM) is ensured by implementing mandatory cyber security controls (MCSR) adopted by the Government. In order to analyze the completeness of the controls, a comparative study was conducted between MCSR and the cyber security standard ISO 27001. The intention to comply with international cyber security standards is reflected in the Strategy on Information Security in the RM for 2019-2024. Compliance with national cyber security controls to international standards will ensure the security of the organization's data and resources by implementing effective, time-verified security controls. Another benefit is the confidence of foreign partners in public organizations of the country, because there will be guarantees that the data provided is confidential, complete and available. It is very important to increase the number of public organizations, certified with the ISO 27001 standard in Moldova in order to ensure the level of compliance with international cyber security requirements. The gap method, which was used in this study, measures the completeness of the MCSR, which is mandatory for public institutions in the Republic of Moldova, compared to the international standard ISO 27001. Based on the results obtained, a series of recommendations were developed which include: the creation of information security management systems (ISMS); performing internal and external audit of systems to meet trends; alignment of the MCSR, issued by the Government of the Republic of Moldova to the security controls of the ISO 27001 standard. It is very important to ensure an acceptable level of cyber security in public institutions in the Republic of Moldova, therefore implementation and certification with international standards is mandatory.
Prediction of Haul Units’ Requirements for the Open Pit Mines Operating Towards Closure
Authors: Salama Abubakary
Published: March 2021

The determination of haul units is one of the important steps in the equipment selection process. The process should aim at minimizing the operational costs and create an optimal match for the haulage system. When open pit mines operating towards closure, reducing the operational costs results in significant gaining, and the savings can be used to implement some of the closure plans. In this paper, the prediction of haul units for an open pit mine which operates towards the final pit limit was analysed using discrete event simulation and multiple linear regressions. The result shows that the changes in production rate have significantly impact on the number of haul units in operations. The obtained P-value suggests that there is a strong correlation between the haul units’ requirement, production rates, and haul distances. This reveals that the prediction of haul units’ requirements can be achieved using a developed regression model. It was observed that, the approach of using discrete event simulation and multiple linear regressions is useful in integrating fleet size decision in a multi-period production schedule.

Authors: Valimba Patrick , Mahe Gil
Published: March 2021

More often daily climate data have been used in hydrological models to estimate flood flows in small data scarce urban and rural catchments where flow peaking and recession are quick within short periods of few hours. This study assesses magnitudes of error of using daily climate data to simulate flood flow hydrographs of a small urban river catchment, Msimbazi River. Spot discharge measurements were available for Apr-May 2014 and MarMay 2015 periods.10-minutes climate records were available at one station, daily temperatures at two stations while daily rainfall records at several stations within the catchment. Visual analysis characterise rainfall events during the 2011, 2014 and 2015 floods, Thiessen-polygon was used for catchment rainfall, Hargreave-Samani model for catchment potential evapotranspiration and flow hydrographs were estimated by calibrated HBV model. Length weighted channel slope was estimated from segment slopes established from available topographical maps and used in estimating time of concentration for the catchment using Kirpich method. Results indicated that simulated flood hydrographs using 10-minutes climate inputs produced higher flood peaks for both December 2011 (peak: 471.6 m3 /s) and April 2014 (peak: 393.5 m3 /s) and expected hydrograph recession behaviour reproducing the Kirpich estimate of time of concentration of 7 hours. Simulated flood peaks using daily climate inputs were 252.3 m3 /s for December 2011 and 205 m3 /s for the April 2014 event being 53% and 52% of those simulated from 10-minutes climate inputs. Despite usefulness of 10-minute climate data, these data are required at more stations within the catchment for reliable simulation of fast receding urban floods and therefore more automatic weather stations are needed in Dar es Salaam.

Hidroituango: How to Reach Adaptive Management to Recover Part of the Ecosystem Connectivity in the Cauca River Basin in Colombia
Authors: Bocanegra Gutiérrez Julián Camilo
Published: March 2021

With the worldwide rapid population increase seen in the past century, the electric energy demand increased also dramatically. In Colombia this led to a boom in the construction of hydroelectric plants in the late 60ies. Today, some accidents while the construction of the biggest plant in the country, Hidroituango, revealed a series of errors made through all those years and opened up a discussion on how to address management focused on the environmental protection of riverine systems in this and similar projects in the Country. Adaptive management has proven to be an effective alternative when giving solutions to this kind of problems. Successful implementation cases have been found in the Colorado and Columbia rivers (In the U.S.A) among others. Similar adaptive management processes can be applied in Colombia. However, there must be considered many local variables as well as political, social, economic and some others interests and complications.
IMPACT OF SOLID WASTE DUMP-SITES ON GROUNDWATER QUALITY IN BENIN CITY, NIGERIA
Authors: Sam-Uroupa R. E. , Ogbeibu E. A.
Published: March 2021

Municipal waste dumpsites contain pollutants which are either water-solution or are capable of being moved along the path of water during percolation through the soil to groundwater. This study was therefore carried out to investigate the impact of solid waste dump-sites in Benin City on the receiving groundwater quality. Four stations were chosen for this study, with each station located within one Local Government Area. These stations were dump-sites at Ikhueniro (station 1), Costain (station 2) and Ugbioyoko (station 3). Omaghe (station 4) was used as the control station without waste dumpsite. Soil samples were collected at three distances from the dump-sites of 0-50m, 50-100m, >100m at 0-30cm depth of top soil and analyzed while the boreholes used were within 120m radius from the dump-sites. This investigation spanned from July 2011 to December 2011. Results showed that water samples were found to be enriched with heavy metals (Fe, Mn, Zn, Cu, Cr, Pb, Ni and V) more than the control water sample; these were however within WHO and FMEnv. regulatory limits for drinking water. The mean pH values of the sampled water fluctuated between 4.50 and 5.57 and were not within the WHO and FMEnv. regulatory limits of 6.5 to 8.5 set for drinking water. ANOVA revealed a highly significant difference (p < 0.01) between the means of the following water parameters; Ca, Na, K, Mg, electric conductivity, Salinity, HCO3, and total soluble solids. The Kruskal-Wallis Test revealed that aerobic bacterial count was significant (p < 0.05) with the highest mean value in station 1 (17.17 x102 cfu/ml) and lowest mean value in station 4 (6.00x102 cfu/ml). Seasonal pattern of variations was observed for water samples examined.

This study aims to accentuate the effect of social realities that influence indigenous horticultural practices. The purpose of which is to help with the understanding of the formation of Amazonian Dark Earths (ADE’s), fertile anthropogenic soil patches that are widespread across Amazonia. A tentative operational chain is proposed, delineating the processes that go into the formation of a garden (swidden), using data collected on the Kayapó and Ka’apor Indians, in order to demonstrate that the choices of technique and technology involved in horticulture are socially conditioned. Combining pedological, biological and geographical approaches with anthropological ethnographies explaining indigenous cosmology helps to elucidate the processes that go into the creation of Amazonia as anthropogenic.

Maior atenção, entretanto, é concedida à Lévy-Bruhl, numa tentativa de contornar algumas dificuldades de leitura de sua obra, rebatendo certas críticas feitas a seus trabalhos e apontando convergências tanto para com Lévi-Strauss quanto para com alguns debates contemporâneos na etnologia. Como conclusão, trago as idéias de “pensamento ameríndio” e de “perspectivismo ameríndio” para fazer uma reflexão sobre uma questão: qual o estatuto da relação entre tais construtos – assim como também do “pensamento selvagem” e da “mentalidade primitiva” – com a etnografia? Sugiro que não são “generalizações”, e que, portanto, não favorecem nem dificultam uma homogeneidade empírica: são, antes, matrizes de pensamento, da ordem do virtual, da potência, cuja relação com o mundo empírico só pode ser uma deatualização.
dom e a teoria ameríndia
Authors: Lanna Marcos
Published: March 2021

Este texto elabora uma concepção ampla do dom, presente em M. Mauss, que inclui tanto objetos materiais como visitas, festas, danças, canções, nomes, direitos inalienáveis sobre territórios e objetos, assim como relações de violência, vingança, roubo e predação. Seu propósito é sugerir a pertinência desta concepção de dom para uma antropologia ameríndia, enfatizando os fenômenos da chefia e do serviço da noiva. Conclui com a hipótese de que a surpreendente generalidade do serviço da noiva pode nos conduzir a investigar de modo fecundo fenômenos aparentemente não relacionados a ele diretamente, como o cativeiro do  guerreiro tupinambá
Job insecurity perceptions in the face of a change in labor legislation among Puerto Rican workers and its impact on productivity during an economic crisis
Authors: Rivera-Guevarrez Rolando , Flecha-Ortiz Jose
Published: March 2021

Job insecurity has evolved in a wide range of phenomena that have been little addressed in the academic literature. One of these phenomena is to observe how the implementation of labor legislation within an economic crisis affects the perception of job insecurity. Thus, this research proposes that organizational justice, organizational support, and employability become three explanatory dimensions that shape job insecurity in the face of a change in labor legislation during an economic crisis. Through a survey of 205 employees of private companies in Puerto Rico and analyzing the data through PLS-SEM, the study demonstrates and supports new literature on how each variable considered affects perceptions of job insecurity and the productivity of human capital in the face of a change in labor legislation, a topic little addressed in the academic literature.

Although many companies are modernizing by maximizing the use of technology, employee management remains an important topic, where employees are the creators of policies, procedures and business strategies. Having employees with high engagement is not easy for a company. So it is always interest to discuss the factors that influence employee engagement. This study aims to analyze the role of employee engagement as a discussion of human resource management, from Khan which focuses on the condition of human psychology, and how this view was developed in the following years by other researchers. This study uses literature study techniques using qualitative methods to describe the results in a narrative and aims to assist further research. The results showed that there was an increase in the engagement topic study. This proves that the management of human resources in an organization must be carried out with high flexibility, with regard to individual rights, by involving employees in organizational processes. Organizations will get high engagement from their employees if communication and relationships between employers and employees are done well, so that a positive perception is created. Engaged employees are an asset for the organization to achieve competitive advantage.
Demonstrative Reference and Cognitive Space: A Memory Game on Mandarin-Speaking Children
Authors: Zhao Lu , Zou Lu
Published: March 2021

The development of pragmatic ability is an essential topic in language acquisition, among which demonstratives are significant to reflect human’s cognition of the relation between language and the environment. The purpose of this research is to investigate the acquisition of spatial demonstratives “zhe” (this) and “na” (that) of Mandarin-speaking children through experimental design (different tool use, e.g. participants pointed at the objects with their finger or a laser pen), exploring the influence of perceptual distance on children’s choice of spatial demonstratives. Through comparison with adults’ data, results supported the view that 5- to 6-year-old children have already developed adult-like cognitive space when it comes to the use of spatial demonstratives, which produced an effect on the use of spatial demonstratives, proving speaker’s subjective involvement in choosing the proximal or distal demonstrative in the process of communication, and rendering more evidence on children’s early development of pragmatic ability.
Quando la febbre non ha una chiara localizzazione: pensa anche alla nefrite focale acuta

Acute lobar nephronia, Diagnosis, Magnetic resonance imaging, Case report Acute lobar nephronia (ALN) is a non-suppurative focal form of acute bacterial infection, generally affecting one or more renal lobules. In the spectrum of upper urinary tract infection ALN is consid-ered a midpoint between uncomplicated pyelonephritis and intrarenal abscess. This condition may be difficult to recognize due to the lack of specific symptoms and laboratory findings. The reported incidence of ALN has increased as a result of advancements in non-invasive imaging techniques such as renal ultrasonography. Computed tomography scanning is the diagnostic gold standard for ALN, but magnetic resonance imagining (MRI) should be considered to limit irradiation and be-cause of its high sensitivity in detecting inflammatory changes in the renal parenchyma. The diag-nosis is relevant since initial intravenous antibiotic therapy and overall length of treatment, usually 3 weeks, are longer respect to those for uncomplicated acute pyelonephritis. The present paper de-scribes the case of a 4-year-old girl with septic fever, sick appearance, elevation of inflammatory indexes with negative blood and urine cultures and non-specific abdominal ultrasonography in which a detailed evaluation of MRI led to the diagnosis of acute lobar nephronia. La nefrite focale acuta (NFA) è una forma focale non suppurativa di infezione batterica acuta, che generalmente colpisce uno o più lobuli renali. Nello spettro delle infezioni delle vie urinarie superiori, l'NFA è considerata un punto medio tra la pielonefrite non complicata e l'ascesso intrarenale. Questa condizione può essere difficile da riconoscere a causa della mancanza di sintomi specifici e risultati di laboratorio. L'incidenza riportata di NFA è aumentata a seguito dei progressi nelle tecniche di imaging non invasive come l'ecografia renale. La tomografia computerizzata è il gold standard diagnostico per l'NFA, ma la risonanza magnetica per immagini (MRI) dovrebbe essere considerata per limitare l'irradiazione e per la sua elevata sensibilità nel rilevare i cambiamenti infiammatori nel parenchima renale. La diagnosi è rilevante poiché la terapia antibiotica per via endovenosa iniziale e la durata complessiva del trattamento, di solito 3 settimane, sono più lunghe rispetto a quelle per la pielonefrite acuta non complicata. Il presente articolo descrive il caso di una bambina di 4 anni con febbre settica, aspetto malato, aumento degli indici infiammatori con emocolture e urine negative ed ecografia addominale aspecifica in cui una valutazione dettagliata della risonanza magnetica ha portato alla diagnosi di nefronia lobare acuta.

A fibropapilomatose (FP) é uma doença multifatorial, neoplásica e infecciosa que afeta todas as espécies de tartarugas marinhas, e o Chelonid alphaherpesvirus 5(ChHV5) tem sido apontado como o agente etiológico primário. Essa doença é caracterizada por tumores cutâneos, mas fibromas viscerais, mixofibromas e fibrossarcomas também têm sido relatados e podem interferir nas funções sistêmicas. Apesar de descrições anteriores de neoplasias viscerais em tartarugas marinhas do Havaí e Flórida, algumas infectadas pelo ChHV5, há poucos relatos de tumores não cutâneos em tartarugas marinhas no Brasil. Para preencher essa lacuna, analisamos amostras de neoplasias internas de quatro tartarugas verdes (Chelonia mydas) através de técnicas histopatológicas e moleculares. Neoplasias cutâneas foram quantificadas e classificadas de acordo com seus tamanhos e escores para determinar a severidade da FP, e a presença de tumores internos foi confirmada postmortem durante necropsia. Quarenta e oito tumores cutâneos (7-23 por indivíduo) foram encontrados nas tartarugas verdes amostradas, e a severidade da FP foi classificada como leve (2 indivíduos) e moderada (2 indivíduos). Neoplasias viscerais foram encontradas em pulmão (n=4), coração (n=1), intestino (n=2), esôfago (n=1), estômago (n=1), fígado (n=1), baço (n=1), músculo esquelético (n=1) e rim (n=2), sendo classificadas como fibromas e uma como mixofibroma renal. Não detectamos DNA do ChHV5 nos fibromas esofágico, muscular esquelético e hepático. Nossa pesquisa relata nova descrição de mixofibroma renal e detecção do ChHV5 em neoplasias viscerais de tartarugas verdes no Brasil, melhorando o conhecimento sobre prevalência, localização anatômica e severidade dos tumores internos associados à FP.
