O lugar de Angola em uma narrativa sobre o Brasil: Desmedida, de Ruy Duarte de Carvalho

O objetivo deste trabalho é investigar, a partir da obra Desmedida: Luanda, São Paulo, São Francisco e volta (Língua Geral, 2010), do angolano Ruy Duarte de Carvalho, a relação entre as geografias desmedidas do sertão brasileiro e o deserto angolano, identificando as principais diferenças e semelhanças no uso literário destes espaços que, segundo o autor, podem ser lidos como uma espécie de “produtores do inédito”. Nossa hipótese é que a noção de “espaço de fronteira”, formulada a partir da relação dialético-dialógica entre o narrador-personagem e João Guimarães Rosa, fornece subsídios que permitem demonstrar algumas das especificidades do percurso histórico de Angola em uma narrativa sobre crônicas do Brasil. Para tanto, nos auxiliaremos dos contributos teóricos de Bakhtin (1988), Glissant (2011) e Mudimbe (2013) e dos estudos críticos sobre a obra de Ruy Duarte, como os de Chaves (2006), Chaves e Can (2016) e Rowland (2008)

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Experimental infection of horses with Vaccinia virus

ABSTRACT: Vaccinia virus (VACV) is the etiologic agent of bovine vaccinia, an emerging zoonotic disease with potential health issues for dairy herds and humans. VACV may occasionally infect other species, including horses. In this sense, an outbreak of VACV disease in horses was described in Pelotas, RS, in 2008, where a co-infection with two VACV strains (named Pelotas Virus 1 [P1V] and Pelotas Virus 2 [P2V]) was detected. Considering the rare occurrence of VACV infection in horses, the objective of this study was to investigate the susceptibility and pathogenesis of VACV infection in this species. Six adult horses were inoculated with VACV P1V or P2V (106.3TCID50/ml) through scarification of the nasolabial surface and monitored for virological and clinical aspects during 28 days. Four inoculated horses (4/6) developed mild lesions in the site of inoculation. Ulcers and scabs restricted to inoculated areas were observed between days 2 and 8 post-inoculation (pi). Microscopically there were acanthosis, ballooning degeneration of the stratum spinosum, necrosis and loss of the epidermis. Infiltration of neutrophils, macrophages and lymphocytes were observed in the dermis. Intracytoplasmic eosinophilic inclusions were infrequently observed in degenerate keratinocytes from adjacent necrotic areas. Virus shedding was detected between days 4 and 8 pi by PCR and virus isolation (infectious virus) from the lesions of one horse inoculated with P2V. No neutralizing antibodies were detected in inoculated animals at day 28 pi. In summary, inoculation of horses with VACV P1V and P2V isolates resulted in a low level of replication and at low frequency, with mild cutaneous lesions, when compared with the course of infection of other susceptible species to VACV. Therefore, horses possibly have a low potential for viral maintenance and transmission to other species, albeit being susceptible to VACV infection

Carcinoma de células escamosas em equino: Relato de caso

Este trabalho objetivou relatar o caso clínico de um equino, macho, sem raça definida, castrado, atendido no Hospital Veterinário do Regimento de Policiamento Montada do Distrito Federal, com uma lesão na genitália externa, diagnosticada como carcinoma de células escamosas (CCE), através de exames histopatológicos e citológicos. O CCE é um tumor maligno cutâneo e invasivo, pode se apresentar em várias áreas tendo predisposição por áreas com pouco pelo e menor pigmentação da pele. Essa neoplasia acomete com frequência a glande peniana dos machos orquiectomizados da raça equina por conta da menor exposição do pênis e acúmulo de esmegma produzido pelas glândulas prepuciais podendo se agravar com a radiação solar. Em virtude do diagnóstico precoce o animal foi submetido ao tratamento cirúrgico, penectomia parcial. No pós-operatório, a limpeza da ferida cirúrgica foi feita com solução de clorexidina a 2%, aplicação manual diária de unguento e administração de hemofarm® (20 mL/dia/ via oral). Aplicação de anti-inflamatório (flunixin meglumine 1,1 mL/Kg/3dias) e analgésico (fenilbutazona 2,2 mL/Kg/5dias consecutivos), ambos por via intravenosa. Os pontos cirúrgicos retirados no 11º dia após a cirurgia, obtendo a recuperação total do animal

Stocks of Carbon in Logs and Timber Products from Forest Management in the Southwestern Amazon

Amazon forest management plans have a variety of effects on carbon emissions, both positive and negative. All of these effects need to be quantified to assess the role of this land use in climate change. Here, we contribute to this effort by evaluating the carbon stocks in logs and timber products from an area under forest management in the southeastern portion of Acre State, Brazil. One hundred and thirty-six trees of 12 species had DBH ranging from 50.9 cm to 149.9 cm. Basic wood density ranged from 0.3 cm−3 to 0.8 g cm−3 with an average of 0.6 g cm−3. The logs had a total volume of 925.2 m3, biomass of 564 Mg, and carbon stock of 484.2 MgC. The average volumetric yield coefficient (VYC) was 52.3% and the carbon yield coefficient (CYC) was 53.2% for logs of the 12 species. The sawn-wood products had a total volume of 484.2 m3, biomass of 302.6 Mg, and carbon stock of 149.9 MgC. Contributions of the different species to the total carbon stored in sawn-wood products ranged from 2.2% to 21.0%. Means and standard deviations for carbon transferred to sawn-wood products per-species from the 1252.8-ha harvested area ranged from 0.4 ± 1.1 MgC to 2.9 ± 0.4 MgC, with the largest percentages of the total carbon stored in wood products being from Dipteryx odorata (21.0%), Apuleia leiocarpa (18.7%), and Eschweilera grandiflora (11.7%). A total of 44,783 pieces of sawn lumber (such as rafters, planks, boards, battens, beams, and small beams) was obtained from logs derived from these trees. Lumber production was highest for boards (54.6% of volume, 47.4% of carbon) and lowest for small beams (1.9% of volume, 2.3% of carbon). The conversion factor for transforming log volume into carbon stored in sawn-wood products was 16.2%. Our results also show that species that retain low amounts of carbon should be allowed to remain in the forest, thereby avoiding low sawmill yield (and consequent generation of waste) and allowing these trees to continue fulfilling environmental functions

Advanced and prospects in phenol wastewater treatment technologies: unveiling opportunities and trends

Abstract This study aims to explore technological advances and prospects in phenol treatment by providing a detailed bibliometric survey of wastewater treatment applications, highlighting innovative advances in research. Using the Web of Science database, we identified 79,104 articles from 2003 to 2023, later refined to 1848. The keywords were used for the initial search: “phenol”, “wastewater”, “degradation”, “treatment” and “removal”. The bibliographic review details the occurrence of journals, authors, newspapers, countries, institutions, keywords, highly cited articles, and prominent predominant research fields. In particular, the field of “Engineering” was responsible for 32% of the published articles, followed by “Ecology of Environmental Sciences” (25%) and “Chemistry” (12%). In addition, a keyword analysis revealed five major groups of clusters that indicate where the research is progressing. This aspect is crucial for understanding the evolution and perspectives of research interests over time. Therefore, future research in the field should prioritize wastewater treatment and feedstock diversification. This focus is essential to address significant challenges, such as production costs, stability, and durability of treatment processes. Graphical Abstrac

An Updated Review of Recent Applications and Perspectives of Hydrogen Production from Biomass by Fermentation: A Comprehensive Analysis

Fermentation is an oxygen-free biological process that produces hydrogen, a clean, renewable energy source with the potential to power a low-carbon economy. Bibliometric analysis is crucial in academic research to evaluate scientific production, identify trends and contributors, and map the development of a field, providing valuable information to guide researchers and promote scientific innovation. This review provides an advanced bibliometric analysis and a future perspective on fermentation for hydrogen production. By searching WoS, we evaluated and refined 62,087 articles to 4493 articles. This allowed us to identify the most important journals, countries, institutions, and authors in the field. In addition, the ten most cited articles and the dominant research areas were identified. A keyword analysis revealed five research clusters that illustrate where research is progressing. The outlook indicates that a deeper understanding of microbiology and support from energy policy will drive the development of hydrogen from fermentation

ATLANTIC BIRD TRAITS: a data set of bird morphological traits from the Atlantic forests of South America

Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra- and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.
