Route to thermalization in the α-Fermi–Pasta–Ulam system

We study the original α-Fermi–Pasta–Ulam (FPU) system with N = 16, 32, and 64 masses connected by a nonlinear quadratic spring. Our approach is based on resonant wave–wave interaction theory; i.e., we assume that, in the weakly nonlinear regime (the one in which Fermi was originally interested), the large time dynamics is ruled by exact resonances. After a detailed analysis of the α-FPU equation of motion, we find that the first nontrivial resonances correspond to six-wave interactions. Those are precisely the interactions responsible for the thermalization of the energy in the spectrum. We predict that, for small-amplitude random waves, the timescale of such interactions is extremely large and it is of the order of 1/ϵ8, where ϵ is the small parameter in the system. The wave–wave interaction theory is not based on any threshold: Equipartition is predicted for arbitrary small nonlinearity. Our results are supported by extensive numerical simulations. A key role in our finding is played by the Umklapp (flip-over) resonant interactions, typical of discrete systems. The thermodynamic limit is also briefly discussed

Suitable Light Regimes for Filming Termites in Laboratory Bioassays

Laboratory bioassays require strategies to minimize stress and keep animals alive as long as the test demands. Sometimes, however, experimental procedures seem notoriously stressful as, for instance, when exposing termites to the illumination needed for video recordings. Being a condition opposed to what termites naturally experience, light might easily stress such insects or might not affect them at all, as they are blind. Here we check for the effects of distinct light regimes on the survival of termites confined in a typical bioassay setup involving footage. The survival of Cornitermes cumulans (Termitidae: Syntermitinae) workers kept in the dark, or subjected to infrared or to cold white light was compared, finding no statistical difference in their survival in these three treatments. While pointing directions for further research on the reasons for such results, we conclude that video recordings of C. cumulans termite workers can be conducted under infrared or cold white LEDs, as these light regimes do not affect the survival of tested individuals

Experiencias y percepciones de los graduados de Odontología sobre la culminación de la tesis en una universidad del Perú

The university thesis represents an academic work where the student demonstrates the research learned skills; however, its completion requires specific skills and subject to limitations. Objective. To identify the perceptions of a group of dental graduates about their experiences while the undergraduate students develop their thesis. Methods. Phenomenological study that interviewed 32 students graduated from the Faculty of Dentistry (Universidad Nacional Mayor de San Marcos, Lima, Peru) through focus groups who successfully completed their degree thesis. The categories of personal, relationship and institutional factors were explored. The analysis was carried out inductively through opinions, search for similarities and synthesis of findings. Results. Three categories of analysis were found: personal, relational and institutional factors. Future job responsibility (personal factor) was perceived as one of the main stimulants to complete the thesis, the motivation of the thesis advisor (relational factor) was perceived as a characteristic that influenced completion while institutional support and data acquisition (institutional factors) were perceived as negative conditions and difficult to cope with. Conclusions. Various factors influence the completion of the university thesis such as: The motivation of the thesis topic, the support of the advisor and having resources to finance the execution were characteristics highlighted as factors that promote the development of the university thesis. These experiences are based on obtaining an academic degree to enter a labor system.La tesis universitaria representa un trabajo académico donde el estudiante demuestra las competencias investigativas aprendidas; sin embargo, su culminación requiere habilidades específicas y sujetas a limitantes.

Desarrollo de lenticelosis en manzanas CV. Royal Gala.

Resumen (Spanish, English) 53 p.Este ensayo se llevó a cabo sobre manzanas cv. Royal Gala durante dos temporadas, con el objetivo de estudiar el desarrollo de lenticelosis. En la primera temporada (2002/03), se realizó un muestreo de la fruta, de un huerto ubicado en la comuna de San Clemente VII Región, diferenciándola en 4 condiciones: Superior-Color, Superior-Verde, Inferior-Color, Inferior-Verde, para confeccionar curvas de evolución tanto para los índices de madurez; así como de las lenticelas de la fruta ante una tinción al vacío con Azul de Toluidina (200ppm). Se midió intensidad de tinción y Nº de lenticelas teñidas/cm2. Se realizaron dos cosechas, manteniendo en cada una de estas la diferencia de ubicación de la fruta en el árbol (superior e inferior). Después de 4 meses de almacenaje a 0°C, la fruta fue sometida a un proceso de selección y embalaje comercial, para evaluar el efecto de éste sobre la incidencia y severidad de Lenticelosis. Para la segunda temporada (2003/04) se almacenó fruta proveniente de la empresa exportadora Dole Chile S.A , reuniéndose un total de cinco diferentes productores, con dos fechas de cosechas. Habiendo trascurrido 2 meses de almacenaje a 0°C, la fruta fue trasladada a la unidad de almacenaje del Centro de Pomáceas, de la U. de Talca, realizándose una evaluación inicial de madurez y Tinción al vacío. La fruta se mantuvo en promedio 4 meses en FC a partir de su cosecha. Al cabo de este periodo, también se le sometió a un proceso de selección y embalaje comercial para evaluar incidencia y severidad de lenticelosis. Los resultados del primer ensayo indicaron que sólo la fruta con color de cubrimiento, mostró una mayor intensidad de tinción en comparación a la fruta sin color de cubrimiento; el factor ubicación en el árbol, no tuvo efecto sobre los parámetros medidos,sin embargo, no hubo desarrollo de lenticelosis. Por otra parte, hubo un cierto grado de asociación entre la técnica de tinción y los índices de madurez Color de Fondo, Firmeza y Almidón, por lo que en un futuro podrían complementar un método de predicción de lenticelosis. Para el segundo ensayo se observó que en la medida que la fruta es sometida a un proceso de selección y embalaje la manifestación de lenticelosis se hizo evidente, por el uso de detergente y altas Tº durante el proceso. Las deferencias en lenticelosis entre ambas temporadas, se explicaría en parte por la presencia de altas T° mínimas (>10°C) durante el periodo de elongación celular de al fruta

School feeding: what children’s drawings reveal

Objective: To identify the perceptions of elementary school children of public schools in Guarulhos, São Paulo, relating to school feeding. Method: a descriptive type study with a qualitative approach. Eighty-two children of 4 schools selected for engaging in educational activities related to eating and nutrition, drawn from the 63 institutions within the municipality were investigated. The drawing technique was the option selected for data collection. Thirteen drawings - those representing the content expressed by a group of children – were presented. The children’s verbalization describing the drawings was recorded and transcribed, along with the content resulting from the analysis of the graphic material, submitted to content analysis. Results: According to the children’s drawings and their respective verbalization, school feeding was associated: with the foods served and those that satisfied their hunger, providing moments of pleasure; within the setting the highlight was the physical structure in which the meals were served and the organization of the line of those waiting to be served and the personal relationships created, representing eating as a moment of companionship, for talking and socializing with friends. Final Considerations: For the children, school feeding acquires a representation that goes beyond the mere act of eating, it is a moment that includes the foodbut also the school setting and relationships with peers. Thus one of the challenges for the administrators and the entire community involved is how to incorporate these dimensions that permeate the meal-time experience and that were observed to be a fundamental and integrating aspect of the school scene.Objetivo: Identificar as percepções das crianças do ensino fundamental de escola públicas do município de Guarulhos, São Paulo, sobre a alimentação escolar. Método: Trata-se de um estudo do tipo descritivo com abordagem qualitativa. Participaram 82 crianças de 4 escolas selecionadas por desenvolverem atividades educativas em alimentação e nutrição, dentre as 63 instituições. Para coleta dos dados optouse pela técnica do desenho e a entrevista com as crianças para sua interpretação do desenho. Foram apresentados 13 desenhos, aqueles representativos de conteúdos expressos por um dos grupos de crianças. As verbalizações das crianças descrevendo os desenhos foram gravadas e transcritas, e juntamente com o conteúdo resultante da análise do material gráfico, submetidos à análise de conteúdo. Resultados: De acordo com os desenhos das crianças e suas respectivas verbalizações, a alimentação escolar estava associada: aos alimentos, os que são ofertados, que estes saciam a fome e trata-se de um momento que proporciona prazer; ao ambiente, o destaque foi para a estrutura física em que eram realizadas as refeições e a organização da fila que se formavam para se servirem e nas relações, representando a alimentação como um momento de convivência, de conversar e socializar com os amigos. Considerações Finais: Para as crianças a alimentação escolar adquire uma representação que extrapola o ato da alimentação, é um momento que engloba a relação com os alimentos, o ambiente escolar e as relações com os pares. Desta forma, um dos desafios para os gestores e toda a comunidade envolvida, é incorporar essas dimensões que permeiam a alimentação e que foram apontados como fundamentais e parte integrante do cenário escolar

Treatment of a post-traumatic stiff knee after an open extensor apparatus injury by arthroscopic arthrolysis through a free flap

Extensor apparatus injury; Open patella fracture; Stiff kneeLesión del aparato extensor; Fractura de rótula abierta; Rodilla rígidaLesió de l'aparell extensor; Fractura de ròtula oberta; Genoll rígidOpen patella fractures have high complication rates. Post-traumatic joint stiffness is particularly common. The management of this complication is even more difficult if free flap was used to cover a soft tissue defect. Late surgical manipulation of free flaps can lead to their failure, with catastrophic consequences. The use of minimally invasive techniques could reduce the associated risks. We present a case of knee stiffness after the fix and flap treatment of a grade IIIB open patella fracture. We performed an arthroscopic arthrolysis with portals through the flap. The pedicle was preoperatively located and avoided. Joint range of motion remarkably improved without records of flap complications. We consider that the technique is feasible. Its success was based on the multidisciplinary collaboration between orthopaedic and plastic surgeons and rehabilitation medicine specialists

Estado, Políticas Sexuais e Cidadania LGBT no Brasil Pós-Impeachment

Este artigo tem como objetivo principal a construção de uma análise conjuntural sobre as políticas sexuais no Brasil, com destaque para as políticas de cidadania LGBT no âmbito do Governo Federal. Nossa narrativa parte de uma análise histórica de tais políticas, concentrando-se fundamentalmente no período de 1996 a 2018, ou seja, do momento de apresentação dos primeiros programas destinados à população LGBT pelo Governo Federal ao atual período de transição político-ideológica da agenda governamental em um Brasil pós-impeachment. Em termos teórico-metodológicos, realizamos uma análise conjuntural, vinculando eventos políticos fragmentados e dispersos em uma narrativa articulada, relacionando conceitos como política sexual e cidadania LGBT para a produção de uma análise do cenário político nacional. Buscamos assim evidenciar os principais fatos políticos que marcaram as relações entre o Estado brasileiro e a sociedade civil no campo das políticas sexuais. Cabe ressaltar que esta narrativa não se conformou enquanto uma análise acabada ou fechada, mas sim como uma possibilidade analítica que intenta trazer novos elementos para refletirmos sobre o contexto político-social brasileiro. Por outro lado, trata-se de uma contribuição teórica ao campo de estudos de gênero e sexualidade, em específico, ao campo de estudos sobre Estado e políticas sexuais
