Taxonomy, allometry, sexual dimorphism, and conservation of the trans-Andean water-snake Helicops danieli Amaral 1937 (Serpentes: Dipsadidae: Hydropsini).
No full textThe extensive lack of knowledge on the morphological aspects of South American water-snakes, includes a poor understanding of phenotypic parameters, intraspecific variation, and conservation of the trans-Andean Helicops species, Helicops danieli Amaral, 1937. For the first time, we provide a multidisciplinary view using key features (e.g., morphology and niche modeling) to improve the taxonomic recognition of this species, as well as describing ontogenetic color changes, allometry, sexual dimorphism, and the conservation status of this poorly studied snake. First, we emended the morphological diagnosis of H. danieli with 23 characters and detected that juvenile tail length is positively related to allometric growth, and that juveniles differ from adults through the presence of the white nuchal collar. Females are larger than males for snout-vent length, whereas males showed proportionally longer tails and smaller head length growth. Suitable areas for H. danieli are restricted to the trans-Andean regions from the Magdalena drainage to the Caribbean coast, which also showed high values of anthropic impacts. Our multidisciplinary approach provided new insights into this South American water snake’s morphology, intraspecific variation, and distribution.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

A ERODIBILIDADE DO SOLO NA BACIA HIDROGRÁFICA DO RIO PINTO, SÃO MIGUEL DO IGUAÇU/PR
No full textA erodibilidade do solo é um dos fatores que contribuem para os processos que regulam a infiltração de água, a resistência do solo à desagregação e o transporte de partículas do solo. O presente trabalho tem por objetivo estimar a erodibilidade dos solos e características de relevo na bacia do rio Pinto, localizada no município de São Miguel do Iguaçu/PR, para posterior utilização dentro da Equação Universal de Perda de solos. Com estas informações será possível nortear produtores rurais na tomada de decisão para a aplicação de técnicas de conservação do solo. Os valores de K atribuídos aos solos neste estudo, foram os propostos por Tomazoni (2003) e Caviglione et. al (2010). A área de estudo pode ser dividida em dois compartimentos com características distintas. No primeiro predominam vertentes longas, com seguimentos retilíneos a ligeiramente convexos, com relevo plano a suave ondulado e declividades entre 0 e 8%. Nessas condições desenvolvem-se predominantemente Latossolos Vermelhos eutroférricos (20,56%) e Nitossolos Vermelhos eutroférricos (56,30%), nestas áreas a errodibilidade é classificada como média. Já no segundo compartimento ocorrem rampas curtas e topos estreitos, convexos, com relevo ondulado a fortemente ondulado e declividade entre 12 e 30%. Nessas condições se desenvolvem predominantemente Cambissolos Háplicos (13,18%), e associação de Neossolos Litólicos eutófico e Neossolos Regolíticos (10,03%), onde a erodibilidade do solo é classificada como muito alta e extremamente alta respectivamente

Previous issue date: 2018-03-28Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPESThis thesis studies the poetics of transcreation in the editions of A asa e a serpente [The Wing and the Serpent] (1979; 1980; 1988; and 2004), from Brazilian writer Vicente Cecim, with the objective of analyzing, from a comparison of the books, how the author?s literary work is carried by the glance of the (in)visible ink. First, it is created a route of the main aspects of the author?s trajectory, in addition to his relationship with contemporary Brazilian literature. In regard to critical reception of his work, diverse opinions are listed based on records present in the initial publication of A asa e a serpente (1979), passing through more specific analysis of Cecim?s creative universe. In conjunction, we discuss the literary composition of Andara?s cycle, which has as vertices, among others, reflections involving the Being and the perception of (in)visible worlds; the imagery of the labyrinth, as an imaginary space and a metalanguage of Vicente Cecim?s writing; the unfinishedness of literary writing itself and silence as a space opened to the creative imagination. In the chapter on theoretical foundation, an explanation is provided on what is the transcreation poetics through the logic of the writer himself, and how that concept suggests means for analyzing the different editions of A asa e a serpente. Lastly, it is outlined a comparison of the editions, resulting in the conclusion that Vicente Cecim delineates a transcreative writing approach centered between the visible and the invisible, culminating in oscillations which become perceptive trough changes in the writing plane and in the graphic project of the books.Cette th?se ?tudie la po?tique de la transcr?ation dans les diff?rentes ?ditions du livre A asa e a serpente (1979, 1980, 1988 et 2004), de l??crivain br?silien Vicente Cecim. L?objectif est d?analyser, ? partir de la comparaison entre les ?ditions, comment se construit l??criture litt?raire de l?auteur par le biais de l?encre (in)visible. Dans un premier temps, on pr?sente un parcours des principaux aspects de la trajectoire de l?auteur, et aussi de sa relation avec la litt?rature br?silienne contemporaine. En ce qui concerne la r?ception critique de son oeuvre, on rassemble des opinions diverses bas?es sur des registres pr?sents dans la premi?re publication de A asa e a serpente (1979), en passant par des analyses plus sp?cifiques l?univers cr?atif de Cecim. De plus, on d?veloppe une ?tude de la composition litt?raire du cycle de Andara, qui a comme vecteurs, entre autres, des r?flexions au sujet de l??tre et des perceptions de mondes (in)visibles, l?image du labyrinthe comme espace imaginaire et du m?talangage de l??criture de Vicente Cecim, l?inachev? de l??criture litt?raire et le silence comme espace ouvert ? l?imagination cr?ative. Dans le chapitre de fondation, on explique ce qu?est la po?tique de la transcr?ation par la logique de l??crivain lui-m?me, et comment ce concept sugg?re les moyens d?analyser les diff?rentes ?ditions de A asa e a serpente. En dernier point, on ?bauche une comparaison entre les ?ditions, ce qui aboutit ? la conclusion selon laquelle Vicente Cecim ?bauche une ?criture transcr?ative qui est centr?e entre le visible et l?invisible. Ceci d?clenche des oscillations qui sont perceptibles ? travers les changements de plan de l??criture et dans le projet graphique des livres.A presente tese estuda a po?tica da transcria??o nas edi??es de A asa e a serpente (1979, 1980, 1988 e 2004), de autoria do escritor brasileiro Vicente Cecim, com o objetivo de analisar, a partir do cotejo entre os livros, como se exerce a escritura liter?ria do autor pelo vi?s da tinta (in)vis?vel. Primeiramente, cria-se um percurso sobre os principais aspectos da trajet?ria do autor, al?m de sua rela??o com a literatura brasileira contempor?nea. No que diz respeito ? recep??o cr?tica de sua obra, elencam-se opini?es diversas com base em registros presentes na publica??o inicial de A asa e a serpente (1979), perpassando por an?lises mais espec?ficas acerca do universo criativo ceciniano. Aliado a isso, discorre-se a respeito da composi??o liter?ria do ciclo de Andara, que tem como v?rtices, dentre outros, reflex?es que envolvem o Ser e as percep??es de mundos (in)vis?veis; a imagem do labirinto, enquanto espa?o imagin?rio e metalinguagem da escrita de Vicente Cecim; o inacabamento da pr?pria escrita liter?ria e o sil?ncio como espa?o aberto ? imagina??o criadora. No cap?tulo de fundamenta??o, explica-se o que ? a po?tica da transcria??o pela l?gica do pr?prio escritor, e de como esse conceito sugere meios de analisar as diferentes edi??es de A asa e a serpente. E, por ?ltimo, delineia-se um cotejo entre as edi??es e A asa e a serpente, que resulta na conclus?o de que Vicente Cecim concebe uma escrita transcriativa que se centra entre o vis?vel e o invis?vel, culminando em oscila??es que s?o percept?veis atrav?s de mudan?as no plano da escrita e no projeto gr?fico dos livro

Observation of quincunx-shaped and dipole-like flatband states in photonic rhombic lattices without band-touching
No full textWe demonstrate experimentally the existence of compact localized states (CLSs) in a quasi-one-dimensional photonic rhombic lattice in the presence of two distinct refractive-index gradients (i.e., a driven lattice ribbon) acting as external electric fields. Such a lattice is composed of an array of periodically arranged evanescently coupled waveguides, which hosts a perfect flatband that touches both remaining dispersive bands when it is not driven. The external driving is realized by modulating the relative writing beam intensity of adjacent waveguides. We find that a y-gradient set perpendicularly to the ribbon preserves the flatband while removing the band-touching. The undriven dipole-like CLS— which occupies two lattice sites over one unit cell—turns into a quincunx-shaped CLS spanned over two unit cells. Instead, an x-gradient acting parallel to the ribbon yields a Stark ladder of the CLS whose spatial profile is unchanged with respect to the undriven case. We notably find that their superposition leads to Bloch-like oscillations in momentum space. © Author(s) 202011Nsciescopu

Da Vinci single-port robotic system current application and future perspective in general surgery: A scoping review
No full textBackground: The da Vinci Single-Port Robot System (DVSP) allows three robotic instruments and an articulated scope to be inserted through a single small incision. It received FDA approval in 2014 and was first introduced in 2018. The aim of this new system was to overcome the limitations of single-incision laparoscopic and robotic surgery. Since then, it has been approved for use only for urologic and transoral surgeries in some countries. It has been used as part of experimental protocols in general surgery. Objective: By obtaining the CE mark at the end of January 2024, DVSP will soon enter the European market. This review aims to comprehensively describe the applications of DVSP in general surgery. Design: A search of PubMed, Embase, and Ebsco databases up to March 2024 was conducted, with registration in PROSPERO (CRD42024536430), following the preferred reporting items for Systematic reviews and Meta-analyses for scoping review (PRISMA-Scr) guidelines. All the studies about the use of DVSP in general surgery were included. Results: Fifty-six studies were included. The following surgical areas of use were identified: transabdominal and transanal colorectal, cholecystectomy, abdominal wall repair, upper gastroesophageal tract, liver, pancreas, breast, and thyroid surgery. The reported surgical and short-term outcomes are promising; a wide range of procedures have been performed safely. Some groups have found advantages, such as faster discharge, shorter operative time, and less postoperative pain compared to multiport robotic surgery. Conclusion: Five years after its initial clinical applications, the use of the DVSP in general surgery procedures has demonstrated feasibility and safety. Hernia repair, cholecystectomy, and colorectal surgery emerge as the most frequently conducted interventions with this robotic system. Nevertheless, there is anticipation for further studies with larger sample sizes and extended follow-up periods to provide more comprehensive insights and data on the long-term outcomes, including the incidence of incisional hernia.

The role of C21ORF2 in flagellum biogenesis in Trypanosomabrucei (T. brucei)
No full textMost eukaryotic cells present a flagellum or cilium which is used for sensory or motility. Therefore, the C21ORF2 gene is linked in the assembly of cilia in mammalian cells. We used scanning electron microscopy to observe the Trypanosoma brucei cells to provide the description of cell morphogenesis and cytokinesis phenotype after 24 hours post induction; where the gene for C21OF2 has been overexpressed. This process was carried out by transfecting Trypanosoma brucei cells with a plasmid that produced more copies of C21ORF2. This plasmid was switched on because tetracycline was added to the media. Here, we reported different characteristics of phenotype, such as the detachment of flagellum, cells in around shape and problem in the cell division. The flagellum plays a crucial role in the pathogenicity of Trypanosoma brucei by providing motility, attachment to the host cell surfaces and sensory functions. I addition we now understand that C21ORF2 gene is involved in regulation of flagellum length, detachment and for problems in cell division. These events showed to be crucial for alteration in cellular shape that may be essential for the continuation of the life cycle of T brucei parasite, which results in excellent strategic for future drug therapy
Analysis of a streaming video feed of a pulverized coal injection system
No full textDanieli Corus supplies tailor-made solutions for the global steel industry. Cameras are used in tuyeres of blast furnaces to detect physical aspects and irregularities. No operator could monitor those videos all day, which is why video analyses are needed. A program is written to analyse a test video and give information about the temperature, the injection of pulverized coal and the movement of rocks. The mathematical background of these calculations is presented, which depend on the transport of light from the blast furnace to the camera through the tuyere. Also the implementation of the calculations can be found. The results are interpreted and discussed and further improvements are suggested
EMOÇÕES POSITIVAS: FATORES INFLUENCIADORES DO COMPARTILHAMENTO DE CONHECIMENTO EM MEMBROS DA EQUIPES DA INDÚSTRIA DE SOFTWARE
No full textKnowledge Management (KM) is an interdisciplinary discipline that proposes ways for an organization to capture, structure, and disseminate knowledge. This knowledge can be developed in the organizational environment, in an appropriate space for the interaction of individuals and sharing in groups. However, other variables can influence the interaction with individuals, one of which may be positive emotions, such as joy, interest, love, and contentment. In this context, the objective of this article is to investigate the factors that influence positive emotions in knowledge sharing among members of the software development team. This research has an applied nature with an exploratory and descriptive objective, in which it comprises the mixed approach and technical procedures of bibliographic survey and field research. A questionnaire was applied, followed by interviews with members of software development teams. The results demonstrate four factors that stimulate the internalization of positive emotions: organizational factor, physical infrastructure factor, collaboration factor, and leadership factor for team integration. In turn, we observed that positive emotions of cheer, contentment, fun, happiness, strength, gratitude, inspiration, pride, optimism, and patience influence the sharing of organizational knowledge.La Gestión del Conocimiento es una disciplina interdisciplinaria que propone maneras para que una organización capture, estructure y difunda el conocimiento.
