Abstract: The use of the ellipsoidal heights of a vessel for measuring the tide allows the diminution of uncertainties of sounding reduction in hydrographic surveys. In this article, the Precise Point Positioning (PPP) and Post-Processing Kinematic (PPK) methods were evaluated by comparing them with data from a tide gauge station while the boat remained moored nearby. When traversing sounding lines, the PPK solution was used as a reference to validate the PPP solution. In all, 12 different periods of surveys were analyzed, distributed throughout the year 2021, in the Guanabara and Ilha Grande Bays, in Rio de Janeiro. The results showed that in comparison with the tide station, when the vessel was moored, the PPK was able to fulfill the strictest criteria (Exclusive Order) of the IHO (International Hydrographic Organization) in 100% of the surveys, while the PPP in 50%. Regarding the use of the PPK as a reference, with the boat both moored and sailing, the PPP met these criteria in 67% for Exclusive Order, 25% for Order 1A and 8% for the 1B. Reducing the vertical uncertainties of hydrographic surveys in shallow waters is useful for all marine and coastal vertical positioning applications, such as integrating terrestrial and marine vertical references.

Polyimides have attracted considerable attention owing to their excellent properties; however, their hydrophilicity makes them susceptible to hydrolytic degradation. In this study, polyaryletherketones (PAEKs) with different fluorine contents were coated onto the surface of the polyimide films to fabricate the hydrophobic surface. The wettability of the films changed, with a transition from hydrophilicity to hydrophobicity, upon coating with PAEKs. Thus, the coated films exhibited low moisture absorption. Due to the excellent thermal stability of fluorinated polyaryletherketones (F-PAEKs), the coated polyimide films retained their hydrophobicity even after extreme treatment. Furthermore, the dielectric properties of the coated polyimide film were superior to those of the unmodified film. The hydrophobic polyimide film can meet the requirements of extreme environments. however degradation study PAEKs (PAEKs changed Thus absorption FPAEKs, FPAEKs F , (F-PAEKs) treatment Furthermore environments (F-PAEKs

Resumo O trabalho analisa o conto «A incrível e triste história da Cândida Erêndira e sua avó desalmada», de Gabriel García Márquez, revelando como se dão as relações dialógicas. A pesquisa bibliográfica e hermenêutica apoiou-se no conceito do fantástico, para explicitação do realismo mágico e daí percorreu um caminho até a análise da ideologia. O realismo mágico caracteriza-se pela inclusão de elementos do fantástico ou mítico na ficção aparentemente realista. A palavra do emissor endereçada ao receptor mostra uma relação social carregada de ideologia. A narrativa em apreço constitui-se na sobreposição de dois parâmetros: o real e o irreal.

Abstract The work analyzes Gabriel García Márquez’s «The Incredible and Sad story of Candida Erendira and Her Soulless Grandmother», revealing how dialogic relationships occur. The bibliographic and hermeneutic research was based on the concept of the fantastic, to explain the magical realism and then followed a path to the analysis of ideology. Magic realism is characterized by the inclusion of elements of the fantastic or mythical in apparently realistic fiction. The sender's word addressed to the receiver shows a social relationship loaded with ideology. The narrative in question is constituted by the superposition of two parameters: the real and the unreal.

RESUMO Este artigo analisa a trajetória de Nancy, uma capitã que construiu sua carreira como pescadora por quase vinte anos, navegando a bordo de navios que cruzam o mar argentino de norte a sul. A partir da história social da classe trabalhadora com uma perspectiva de gênero, este trabalho visa reconstruir e investigar alguns traços da vivência dessa mulher, não por sua singularidade, mas por possibilitar o ingresso em uma valiosa análise em torno da generização do ambiente de trabalho, a situação desigual da mulher trabalhadora -especialmente na indústria pesqueira- e os vínculos entre o patriarcado e o capitalismo desde as últimas décadas do século XX e o início do presente. Assim, as páginas a seguir abordarão a vida de Nancy em sua complexidade, restaurando em no tecido social de sua família, na cidade em que viveu sua infância e juventude, e em seu ambiente de trabalho, com o objetivo de compreender como o indivíduo se relaciona com estruturas, e como mandatos, símbolos e inscrições impactam as formas de lembrar e significar o passado.

ABSTRACT This article analyzes the life path of Nancy, a woman captain who built her career as a fishing worker during almost twenty years, sailing on ships that travel the Argentinian Sea from North to South. From the social history of the working class with a gender perspective, this paper aims to reconstruct and investigate some traces of this woman´s experience, not because of its uniqueness, but because it enables access to a valuable analysis around the gendered of the workspace, the unequal situation of working womens -especially in the fishing factory- and the links between patriarchy and capitalism since the last decades of the 20th century and the beginning of the present. Thus, the following pages will address Nancy's life in its complexity, restoring her in the social framework of her family, of the city in where she lived his childhood and youth, and her workspace, with the purpose of understanding how the individual is related to structures, and how mandates, symbols and inscriptions impacts in the ways of remember and mean the past.

RESUMEN La misión LightSail-2 de la Planetary Society validó con éxito la capacidad de maniobra orbital de una nave impulsada por la presión de la radiación solar (PRS). Presentamos un estudio sobre dos estrategias distintas para la orientación de una vela solar. El objetivo es aumentar el efecto de la aceleración por la PRS a lo largo de la trayectoria orbital de la nave, con la intención de mantener o incrementar con el tiempo la altitud. Además, una de las estrategias se usó para determinar la posibilidad de mantener la altitud promedio de la nave al variar algunos parámetros de la misión. Los resultados muestran que es posible aumentar con el tiempo la altitud promedio de la nave, mientras que se reduce el número de maniobras necesarias para cambiar la orientación de la nave. Con este resultado se ve que también es posible modificar algunos parámetros de la misión sin afectar el desempeño de la vela solar.

ABSTRACT The Planetary Society’s LightSail-2 mission successfully validated the orbital maneuvering capability of a solar radiation pressure (SRP) propelled spacecraft. This paper presents a study on two alternative attitude strategies for the orientation of a solar sail. The goal is to increase the effect of the SRP acceleration over the spacecraft’s orbital trajectory, with the intention of maintaining or even gaining altitude over time. Furthermore, one of these strategies was employed while varying a few of the mission’s parameters to determine if it would be viable to maintain the spacecraft’s average altitude. Results show that it is possible to increase the average altitude of the spacecraft over time while still reducing the number of maneuvers necessary to change the spacecraft’s attitude. With that result in hand, it is also possible to change some of the mission parameters without compromising the solar sailing performance.

The nautical term ύποπλέω is a hapax legomenon used twice in Acts 27 in the context of Paul's captivity voyage to Rome. This article begins by examining how the word has been translated in verses 4 and 7 in relation to other sailing terms in the chapter. The varying translations, particularly of verse 4, are dependent on the interpretation of the journey's route. Next the depiction of the journey in some Bible atlases is discussed. The atlases typically show two different routes around Cyprus, again dependent on how ύποπλέω is interpreted. The voyages of Herod and Lucian in the north-eastern Mediterranean are also examined for interpretative clues. Mediterranean geography, nautical archaeology, and seafaring praxis will also contribute to a suggested translation and interpretation of the word's uses in this pericope in Acts.

Dentre os experimentos mais importantes do século XIX está um que liga o eletromagnetismo com a mecânica de forma direta. No chamado “Radiômetro de Crookes” a luz, empurrando palhetas, surpreende dando a imediata percepção de sua energia. O público percebe que o lado preto é quem recebe a maior ação. O estudante de escola, e o universitário, tentam entender o porquê disso, mas ficam com dúvidas. Neste artigo fazemos um recenso das dúvidas que acontecem, em nível de escola, graduação, e pós-graduação. É comum pensar em termos de eletromagnetismo, de termodinâmica, mas não conhecemos artigo algum que tenha incluído o atrito na análise. Mostramos aqui a influência do atrito por meio de um experimento simples.

One of the most important experiments of the 19th century makes a connection between electromagnetism and mechanics in a direct way. In the so called “Crooke’s Radiometer” the light, pulling vanes, surprises us giving the immediate perception of its energy. The public perceives that is the black side which receives the greater action. The school and the universitarie’s students, they try to understand why it is so, but doubts remain. In this article we make a review of those doubts at three levels: school, graduation and post-graduation. The usual thinking employs electromagnetism, thermodynamics, but we do not know any article which who may had included friction on the analysis. We show here the influence of friction by performing a simple experiment.

Resumo Neste artigo, meu objetivo é analisar a produção de ‘prestígio’, reputação e memória entre vaqueiros do sertão de Pernambuco a partir de suas relações com o corpo, os animais e o território. Para tanto, demonstro que a exaltação de uma vida de sacrifícios e as tarefas concernentes ao ofício do vaqueiro resultam de diversas de suas práticas e de seus conhecimentos, mas também de sua habilidade retórica de narrar e reconstruir acontecimentos passados. Nas práticas denominadas ‘pega de boi’, vaqueiros, animais e caatingas surgem como seres em disputa, buscando triunfar uns em relação aos outros. Para analisar essas práticas, o material etnográfico ao qual recorro são narrativas de um ‘vaqueiro velho’ cuja particularidade no modo de confeccionar oralmente as suas experiências passadas expressa de uma só vez a importância do corpo, da memória e dos animais no cotidiano dos vaqueiros.

Abstract In this article, my objective is to analyze the production of prestige, reputation and memory among cowboys of the sertão of Pernambuco, focusing in their relations with body, animals and territory. I demonstrate that the exaltation of a life of sacrifice and the tasks concerning the cowboy’s craft result from several of his practices and knowledges, but also from his rhetorical ability to narrate and to reconstruct past events. In the practices known as pegas de boi, cowboys, animals and the native vegetation (caatinga) appear as beings in dispute, seeking to triumph over each other. In order to analyze these practices, the ethnographic material to which I refer are narratives of an old cowboy whose particularity in the way of making orally his past experiences expresses at once the importance of body, memory and animals in the daily life of the cowboys.

Conclusión. El principal hallazgo del estudio fue la correlación significativa y positiva entre la cooperación condicionada y todos los componentes de la ansiedad competitiva.

Abstract Objective. This study analyses the connection between competitive anxiety and sporting cooperation of racing sailors from the Balearic Islands (Spain). We used a sample of 46 sailors from the Balearic Islands (Mage = 31.9; SDage = 16.32), from different levels. Method. The Sport Anxiety Scale (Smith, Smoll, & Schutz, 1990) questionnaire was used to measure the competitive anxiety and the “Cuestionariode Cooperación Deportiva” (Sporting Cooperation Questionnaire) (García-Mas et al., 2006) was applied to study cooperation. The data was collected electronically, and a descriptive and correlational analysis was carried out with them. Results. The statistical analysis showed positive and significant correlations between conditioned cooperation willingness and all components of the anxiety variable (Somatic = 0.47, Worry = 0.51, Distraction = 0.52 y Global = 0.59). A positive correlation was also found between global anxiety and its cognitive components, particularly in the worry anxiety (W = 0.91 y D = 0.84). Conclusion. The main finding of this study was the significant and positive correlation between the conditioned cooperation and all components of the competitive anxiety.

ABSTRACT Purpose: To make a further evaluation of perioperative outcomes between the robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we conducted a comparison and trend analysis by using the Nationwide Inpatient Sample (NIS) from 2009 to 2014. Materials and Methods: Adult prostate cancer patients with radical prostatectomy were abstracted from the NIS. RARP and ORP were identified according to the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The perioperative outcomes included blood transfusion, intraoperative and postoperative complications, prolonged length of stay (pLOS), and in-hospital mortality. Propensity score matching method and multivariable logistic regression model were performed to adjust for the pre-defined covariates. The annual percent change (APC) was used to detect the change trend of rates for outcomes. Results: A total of 77.054 patients were included in our study. According to the results of propensity score matching analyses, RARP outperformed ORP in blood transfusion (1.96% vs. 9.40%), intraoperative complication (0.73% vs. 1.25%), overall postoperative complications (8.87% vs. 11.97%), and pLOS (13.39% vs. 36.70%). We also found that there was a significant decreasing tendency of incidence in blood transfusion (APC=-9.81), intraoperative complication (APC=-12.84), and miscellaneous surgical complications (APC=-14.09) for the RARP group. The results of multivariable analyses were almost consistent with those of propensity score matching analyses. Conclusions: The RARP approach has lower incidence rates of perioperative complications than the ORP approach, and there is a potential decreasing tendency of complication incidence rates for the RARP.

This article analyzes the impact of the transition from sailing to steamships on the Argentine coast. To do this, first, we make an introduction about the totals of boats, fluvial and maritime of the last decades of the nineteenth century and the first decades of the twentieth that traveled the region. Secondly, we focus on river traffic and finally on the participation of the different ports in the dynamics, establishing their participation in the circulation of values and of the different goods transported. Our goal is to establish the impact that this transition had on the territory. The sources with which the research was approached are official: Censuses, Foreign Trade Yearbooks and Trade Reports.

Abstract This investigation proposes an interpretation of the second to last scene of the movie No country for old men (2007), directed by Joel and Ethan Coen. The film is an adaptation of the same name novel of Corman McCarthy (2005), and at the same time, this is an interpretation of the poem Sailing to Byzantium of William Butler Yeats (1928). Although the cinematographic result has a direct relationship with the novel, it also does it to the poem, however not in an evident way. Furthermore, this text analyzes both the second to last scene of the movie and the poem, in order to suggest a relationship between them.

Resumen La presente investigación propone una lectura de la penúltima escena de la película: No country for old men (No es país para viejos) (2007) de los hermanos Joel y Ethan Coen. El filme es una adaptación de la novela homónima de Cormac McCarthy (2005) y ésta, a su vez, es una interpretación del poema Sailing to Byzantium de William Butler Yeats (1928). Si bien el resultado cinematográfico guarda una relación directa con el argumento de la novela, también lo hace con el poema, pero no de manera evidente. De modo que el presente texto analiza tanto la penúltima escena de la película como el poema, para platear una relación entre ellos.
