The shelf-life of the vegetable-type soybean pods stored under different conditions was evaluated by chemical characteristics and color. The pods were harvested in the R6 stage and stored either at 30 or 7ºC for 9 d. After the storage period, the pods were blanched and threshed, and the immature green grains were used for the analysis. The protein content decreased after 6 d of storage at 7ºC. There was no difference in the lipid content after the storage at 30 and 7ºC for 9 d. The starch and sucrose contents decreased after the first day of storage at 30ºC. There was no difference in trypsin inhibitor activity until 6 d of storage at 30 and 7ºC. The green color of the pods that was an indication of the quality that was maintained when stored at 7ºC during 3 d. To preserve the quality of vegetable-type soybean, pods should be stored at 30ºC and consumed within 24 h or stored at 7ºC for up to 3 d of storage.

Devido à maior concentração de isoflavonas nos hipocótilos dos grãos de soja, a indústria de alimentos tem utilizado esse componente do grão como matéria-prima. No presente trabalho, foram quantificados os teores de isoflavonas nas estruturas formadoras do grão de soja (hipocótilo, cotilédones e casca), analisadas por Cromatografia Líquida de Alta Eficiência (CLAE). Foram avaliadas quatro cultivares de sojas especiais: BRS 184, BRS 216, BRS 257 e BRS 267, desenvolvidas pela Embrapa Soja. Todas as cultivares apresentaram maior teor de isoflavonas totais no hipocótilo (média de 2029,32 mg.100 g-1). No grão inteiro (267,16 mg.100 g-1) e nos cotilédones (209,16 mg.100 g-1), os teores de isoflavonas foram cerca de dez vezes menores do que nos hipocótilos. A cultivar BRS 216 apresentou o teor maior de isoflavonas totais no hipocótilo (2583,20 mg.100 g-1). Embora a casca da soja não apresente isoflavonas, observou-se que esses compostos estavam presentes nessa parte do grão numa quantidade média de 105,58 mg.100 g-1, devido à presença de resíduos do hipocótilo e dos cotilédones provenientes do processo de descasque. Essa composição residual da casca favorece sua utilização como matéria-prima fonte de fibras, porque também fornece isoflavonas e outros compostos da soja.Due to the higher concentration of isoflavones in the soybean hypocotyls, the food industry has used this component of the bean as a raw material. This paper reports the isoflavone contents found in the different parts of the bean (hypocotyl, cotyledon and hull) as analyzed by High Performance Liquid Chromatography (HPLC). Four special soybean cultivars, BRS 184, BRS 216, BRS 257 and BRS 267, developed by Embrapa Soybean, were evaluated. All the cultivars presented higher contents of total isoflavones in the hypocotyls (average of 2029.32 mg.100 g-1). The isoflavone contents of the whole beans (267.16 mg.100 g-1) and the cotyledons (209.16 mg.100 g-1) were about 10 times lower than that of the hypocotyls. Cultivar BRS 216 presented the highest total isoflavone content in the hypocotyl (2583.20 mg.100 g-1). Although soybean hulls do not contain isoflavones, an average of 105.57 mg.100 g-1 was found in this component, due to the presence of hypocotyl and cotyledon residues resulting from the hulling process. This residual composition of the hulls favors their use as a raw material that is a source of fibers, also providing isoflavones and other soybean compounds.

One may notices, through out brazilian literary historiography, specially in novels and texts by male authors, that female celibate personages play supporting roles, have a patology of some form, are ridiculized and subjected to family interdition accordant to social standarts contemporary. This paper means to speculate how the “spinster” gains voice and representation while playing leading roles in short stories. To support this analysis, the short stories Miss Algrave, by Clarice Lispector, Sr. Diretor, by Lygia Fagundes Telles and Príncipe Sapo, by Caio Fernando Abreu, are studied and analysed through the optical of three thematics plains: interdiction, eroticism and solitude. As motivacional theorist elements, this paper will considerate the eroticism perceptions according to Octavio Paz, the historiographic studie about the “spinster” by Claudia Maia, and the concept of “texto tagarelice” by Roland Barthes.

A investigação relativa à exploração do petróleo no estado do Espírito Santo e a interferência do Poder Judiciário é de extrema importância, tendo em vista que a referida atividade econômica atrai muitos recursos financeiros para esse ente federativo. No entanto, há que se considerar que a exploração de petróleo, embora extremamente lucrativa, apresenta grande risco ambiental. Daí a necessidade de prevenção e avaliação desses riscos. Como se sabe, antes da exploração de uma atividade econômica potencialmente danosa ao meio ambiente é necessária a elaboração de um estudo prévio de impacto ambiental, a fim de prevenir os danos ao meio ambiente. Após esse estudo,o administrador pode emitir licença ambiental para a exploração da atividade econômica, ou não. É nesse momento que o Poder Judiciário pode ser convocado a intervirem uma atividade típica da Administração Pública, com o intuito de tentar preservar um direito fundamental, que é o meio ambiente ecologicamente equilibrado. Todavia, essa interferência pode gerar diversas discussões envolvendo, inclusive, a própria legitimidade de atuação desse Poder. Assim, o presente texto aborda o tema “controle da Administração Pública pelo Poder Judiciário”, tendo como base a investigação bibliográfica e jurisprudencial.

This paper analyzed the most important aspects for the success of crowdfunding projects observing the Kickante platform, an important crowdfunding Brazilian platform. We found that the total value per project increased with the number of investors. The value per investor increased with the minimum value invested with rewards and with certain types of promoters (like informal groups or new companies) or with startups.

This work describes the production of electronic-skin (e-skin) piezoresistive sensors, which micro-structuration is performed using laser engraved molds. With this fabrication approach, low-cost sensors are easily produced with a tailored performance. Sensors with micro-cones and a high sensitivity of −1 kPa−1 under 600 Pa are more adequate for the blood pressure wave detection, while sensors micro-structured with semi-spheres and a maximum sensitivity of −6 × 10−3 kPa−1 in a large pressure range (1.6 kPa to 100 kPa) are more suitable for robotics and functional prosthesis.

This work analyses the representation of death under the sign of the “mask” in Hilda Hilst’s poetics. Among the selected topics that are taken into consideration we focus on the discursive and poetic metaphors seen in Da morte. Odes mínimas (1980), and also the spacial transposition seen in the writer`s house and grave. Another objective of this article is to consider how the author elaborates her own death and also the death of her work in interviews given to the press. The theoretical approaches used are Biografema, by Roland Barthes and Mortes imaginárias, by Michel Schneider

While there have been important advances within wireless communication technology, the provision of communication support during disaster relief activities remains an open issue. The literature in disaster research reports several major restrictions to conducting first response activities in urban areas, given the limitations of telephone networks and radio systems to provide digital communication in the field. In search-and-rescue operations, the communication requirements are increased, since the first responders need to rely on real-time and reliable communication to perform their activities and coordinate their efforts with other teams. Therefore, these limitations open the door to improvisation during disaster relief efforts. In this paper, we argue that flying ad-hoc networks can provide the communication support needed in these scenarios, and propose a new solution towards that goal. The proposal involves the use of flying witness units, implemented using drones, that act as communication gateways between first responders working at different locations of the affected area. The proposal is named the Flying Real-Time Network, and its feasibility to provide communication in a disaster scenario is shown by presenting both a real-time schedulability analysis of message delivery, as well as simulations of the communication support in a physical scenario inspired by a real incident. The obtained results were highly positive and consistent, therefore this proposal represents a step forward towards the solution of this open issue.

FUNDAMENTO: O suporte cardiopulmonar com oxigenador de membrana é um método de ressuscitação de distúrbios hemodinâmicos, pulmonares ou ambos, consagrado em centros internacionais. OBJETIVOS: Descrever diversos aspectos relacionados ao suporte cardiopulmonar com oxigenador de membrana em um serviço de cirurgia cardiovascular nacional e determinar seus resultados imediatos e tardios. MÉTODOS: Entre outubro de 2005 e janeiro de 2007, 10 pacientes foram submetidos a suporte circulatório e/ou respiratório em candidatos ou submetidos a cirurgia cardiovascular pediátrica, com idade mediana de 58,5 dias (40% de neonatos) e peso mediano de 3,9 kg. O suporte foi mantido com a intenção de recuperação e desmame, de acordo com critérios clínicos e ecocardiográficos diários. O suporte foi descontinuado nos pacientes sem indicação de transplante, com incapacidade de recuperação e com sobrevida limitada, de acordo com julgamento multidisciplinar. RESULTADOS: O suporte circulatório foi utilizado no pós-operatório de operações corretivas ou paliativas em 80% e no pré-operatório no restante. Instabilidade hemodinâmica grave irresponsiva (40%), falência miocárdica na saída de circulação extracorpórea (20%) e parada cardíaca no pós-operatório (20%) foram as indicações mais freqüentes. O tempo médio de permanência em suporte circulatório foi de 58 ± 37 horas. O suporte foi retirado com sucesso em 50% e 30% obtiveram alta hospitalar. A sobrevida atuarial foi de 40%, 30% e 20% aos 30 dias, 3 meses e 24 meses, respectivamente. CONCLUSÃO: O suporte cardiopulmonar com oxigenador de membrana foi um método eficaz e útil na ressuscitação de distúrbios cardiovasculares e pulmonares graves no perioperatório de cirurgia cardiovascular pediátrica.BACKGROUND: Extracorporeal membrane oxygenation is a well-documented resuscitation method in patients with severe hemodynamic and/or respiratory impairment. OBJECTIVE: To describe several aspects related to the use of extracorporeal membrane oxygenation in a pediatric heart center and determine its immediate and late outcomes. METHODS: Between October 2005 and January 2007, 10 patients who were submitted to pediatric cardiac surgery underwent extracorporeal membrane oxygenation implant. Median age was 58.5 days (40% neonates) and median body weight was 3.9 kg. Circulatory assistance was initiated aiming at the recovery and the weaning protocols followed daily clinical and echocardiographic criteria. Support was discontinued when transplant was contraindicated, when the patient was unable to recover or when survival was considered to be limited by a multidisciplinary team. RESULTS: Extracorporeal membrane oxygenation was employed after corrective or palliative heart surgery in 80% and preoperatively in the remaining ones. It was most often indicated for irresponsive hemodynamic instability (40%), post-cardiotomy shock (20%) and post-cardiac arrest (20%). The mean duration on support was 58 ± 37 hours. Weaning was successfully in 50% of the cases and 30% were discharged home. Actuarial survival was 40%, 30% and 20% at 30 days, 3 months and 24 months, respectively. CONCLUSION: Extracorporeal membrane oxygenation is an effective and useful tool for the resuscitation of patients presenting severe hemodynamic and/or respiratory failure in the perioperative period of pediatric cardiovascular surgery.

PURPOSE: A variety of predictive factors for the evolution of arterial grafts in patients with critical ischemia have been well defined in clinical studies, including diabetes mellitus, dialytic renal insufficiency, smoking, and distal arterial runoff. The goal of this study was to determine whether patients with critical ischemia undergoing arterial reconstruction in which ischemic lesions appeared spontaneously, compared to those in which the ischemic lesion appeared following an external aggression to the limb present different patterns of evolution. METHODS: From February 2002 to January 2004, 100 patients undergoing infra-inguinal arterial reconstruction were followed. They were divided into 2 groups: 1) the spontaneous group (n = 52), comprising individuals presenting with ischemic lesions of spontaneous origin and 2) the external aggression to the limb group (n = 48), comprising individuals for which an external causal mechanism for the appearance of the ischemic lesion was identified. The variables analyzed were limb salvage and graft functioning rates. RESULTS: Patients with spontaneous lesions had rates of limb salvage and graft functioning significantly lower than those for patients with lesions that were secondary to external aggression (42.3% versus 87.5%, respectively for both outcomes; P OBJETIVO: Diversos fatores preditivos de evolução de enxertos arteriais em pacientes com isquemia grave foram definidos em estudos clínicos como diabetes mellitus, insuficiência renal, fumo e vasão distal. O objetivo deste estudo foi verificar se pacientes com isquemia grave submetidos a revascularização nos quais as lesões apareceram espontaneamente apresentam evolução diferente daquela em que as lesões apareceram após uma agressão externa ao membro. MÉTODOS: De fevereiro de 2002 a janeiro de 2004, 100 pacientes submetidos a revascularizações infra-inguinais foram seguidos. Eles foram divididos em 2 grupos: 1) Grupo com lesão espontânea (52 pacientes), que compreendia pacientes apresentando lesões isquêmicas de origem espontânea e 2) Grupo de lesão por agressão externa (48 pacientes) que compreendia pacientes em que um mecanismo externo era identificado como causa do aparecimento da lesão isquêmica. As variáveis analisadas foram salvamento de membro e índices de perviedade dos enxertos. RESULTADOS: Pacientes com lesão espontânea apresentam índices de salvamento de membro e perviedade do enxerto significativamente menores que pacientes com lesões secundárias a agressão externa (42,3% x 87,5%, respectivamente para ambos itens de estudo;p

Underwater sensor networks represent an important and promising field of research due to the large diversity of underwater ubiquitous applications that can be supported by these networks, e.g., systems that deliver tsunami and oil spill warnings, or monitor submarine ecosystems. Most of these monitoring and warning systems require real-time communication in wide area networks that have a low density of nodes. The underwater communication medium involved in these networks is very harsh and imposes strong restrictions to the communication process. In this scenario, the real-time transmission of information is done mainly using acoustic signals, since the network nodes are not physically close. The features of the communication scenario and the requirements of the communication process represent major challenges for designers of both, communication protocols and monitoring and warning systems. The lack of models to represent these networks is the main stumbling block for the proliferation of underwater ubiquitous systems. This paper presents a real-time communication model for underwater acoustic sensor networks (UW-ASN) that are designed to cover wide areas with a low density of nodes, using any-to-any communication. This model is analytic, considers two solution approaches for scheduling the real-time messages, and provides a time-constraint analysis for the network performance. Using this model, the designers of protocols and underwater ubiquitous systems can quickly prototype and evaluate their solutions in an evolving way, in order to determine the best solution to the problem being addressed. The suitability of the proposal is illustrated with a case study that shows the performance of a UW-ASN under several initial conditions. This is the first analytic model for representing real-time communication in this type of network, and therefore, it opens the door for the development of underwater ubiquitous systems for several application scenarios.

O interesse no estudo dos profissionais passa fundamentalmente pela possibilidade de compreensão dos processos de circulação das ideias urbanísticas e sobre os problemas e desafios urbanos de um modo geral. Foram (e são) essas ideias que estruturaram (estruturam) os debates sobre melhoramentos urbanos e planos urbanísticos, planos diretores, planos regionais, o desenvolvimento social-urbano a construção-institucionalização do urbanismo no Brasil, especialmente a institucionalização do campo disciplinar do urbanismo como prática profissional de atuação nas administrações municipais para soluções dos “problemas urbanos”: neste caso especialmente pela atuação de engenheiros e urbanistas. Ao mesmo tempo, essas mesmas ideias têm papel importante, mesmo fora do campo dos especialistas, ao instruir paulatinamente as formas de apreensão e entendimento do urbano.

OBJETIVO: Descrever as lesoes morfológicas, macro e microscópicas, associadas ao marcapasso definitivo (MP) em coraçoes de pacientes falecidos com cardiopatia chagásica crônica e compará-las com as descritas em outras cardiopatias. MÉTODO: Foram estudados 22 coraçoes de pacientes chagásicos crônicos (16 homens e seis mulheres) de 26 a 86 anos de idade (média de 54 anos) portadores de MP definitivo endocárdico. Foram retirados fragmentos das paredes das quatro câmaras, do septo interventricular e da ponta cardíaca, bem como de tecidos que envolviam os cabos-eletrodos e de áreas de aderências para processamento histológico. As características do exsudato leucocitário nos sítios de implante e no miocárdio ventricular foram analisadas por meio da técnica de imuno-histoquímica. RESULTADOS: Inflamaçao e trombose nos sítios de implante resultaram em encapsulamento fibroso das pontas dos cabos-eletrodos que permaneceram firmemente aderidos ao endocárdio adjacente. Nos sítios de implante, linfócitos B e T ocorreram em proporçoes semelhantes, diferentemente dos focos da miocardite chagásica ventricular, na qual foi observado marcante predomínio de linfócitos T. CONCLUSAO: Os cabos-eletrodos nao sao estruturas biologicamente inertes; sua permanência produz constante estímulo trombogênico, assim como processo inflamatório e fibrogênico nos sítios dos implantes. A organizaçao de trombos vermelhos e/ou de fibrina que se formam em torno dos cabos-eletrodos parece responsável por seu encapsulamento e por frequentes aderências às estruturas adjacentes. As lesoes cardíacas associadas aos MP na cardiopatia chagásica crônica dos casos estudados foram semelhantes às descritas em outras cardiopatias.

Infectious diseases can cause deleterious effects on bird species, leading to population decline and extinction. Haemosporidia can be recognized by their negative effects on host fitness, including reproductive success and immune responses. In captivity, outbreaks of haemosporidian infection have been observed in birds in zoos and aviaries. The endemic Brazilian Atlantic rainforest species Aburria jacutinga is one of the most endangered species in the Cracidae family, and wild populations of this species are currently found mainly in conservation areas in only two Brazilian states. In this study, we aimed to evaluate the effects of avian haemosporidia on hematological and biochemical parameters in two captive populations of A. jacutinga. Forty-two animals were assessed, and the haemosporidian prevalence was similar for males and females. The occurrence of haemosporidian infection in captive A. jacutinga observed in this study was similar to results found in other captive and wild birds in Brazil. We found three different lineages of haemosporidia. Two lineages were identified as Plasmodium sp., one of which was previously detected in Europe and Asia, and the other is a new lineage closely related to P. gallinaceum. A new third lineage was identified as Haemoproteus sp. We found no significant differences in hematological and biochemical values between infected and non-infected birds, and the haemosporidian lineage did not seem to have an impact on the clinical and physiological parameters of A. jacutinga. This is the first report on an evaluation of natural haemosporidian infections diagnosed by microscopic and molecular methods in A. jacutinga by hematology, blood biochemistry, and serum protein values. Determining physiological parameters, occurrence and an estimation of the impact of haemosporidia in endangered avian species may contribute to the management of species rehabilitation and conservation.

Trajetória ou biografia? Uma ou outra seriam aproximações indistintas para estudos sobre a experiência vivida por algum personagem? Poderíamos dizer que a ideia de trajetória remete imediatamente ao aspecto profissional dessa experiência pessoal e, portanto, equivaleria à trajetória profissional? Seria a biografia justificável somente pela abordagem da experiência pessoal, por uma suposta singularidade? Ou ainda, seria possível falar em biografia profissional, como uma “entrada” híbrida, que remeteria necessariamente para a experiência profissional e pessoal, entrecruzadas? Sem eleger, de antemão, uma entre essas abordagens, a proposta do dossiê “Os eruditos e a cidade” apresenta uma oportunidade para se discutir o tema.

Pervasive data sensing is a major issue that transverses various research areas and application domains. It allows identifying people’s behaviour and patterns without overwhelming the monitored persons. Although there are many pervasive data sensing applications, they are typically focused on addressing specific problems in a single application domain, making them difficult to generalize or reuse. On the other hand, the platforms for supporting pervasive data sensing impose restrictions to the devices and operational environments that make them unsuitable for monitoring loosely-coupled or fully distributed work. In order to help address this challenge this paper present a framework that supports distributed pervasive data sensing in a generic way. Developers can use this framework to facilitate the implementations of their applications, thus reducing complexity and effort in such an activity. The framework was evaluated using simulations and also through an empirical test, and the obtained results indicate that it is useful to support such a sensing activity in loosely-coupled or fully distributed work scenarios.

Underwater sensor networks are becoming an important field of research, because of their everyday increasing application scope. Examples of their application areas are environmental and pollution monitoring (mainly oil spills), oceanographic data collection, support for submarine geolocalization, ocean sampling and early tsunamis alert. The challenge of performing underwater communications is well known, provided that radio signals are useless in this medium, and a wired solution is too expensive. Therefore, the sensors in these networks transmit their information using acoustic signals that propagate well under water. This data transmission type not only brings an opportunity, but also several challenges to the implementation of these networks, e.g., in terms of energy consumption, data transmission and signal interference. In order to help advance the knowledge in the design and implementation of these networks for monitoring underwater spaces, this paper proposes a MAC protocol for acoustic communications between the nodes, based on a self-organized time division multiple access mechanism. The proposal was evaluated using simulations of a real monitoring scenario, and the obtained results are highly encouraging.

In this paper, the state-of-the-art on the field of Information and Communications Technolo- gies (ICTs) in Latin America is presented. Its main contribution consists in the localization of common objectives for the majority of the countries in the region. Although the countries are very heterogeneous from the cultural and geographical perspectives, there are many common factors that can be exploited in order to develop their economies. At first sight, Brazil or Mex- ico with their huge populations and big economies are giants compared to other countries like Bolivia or Costa Rica. However there are many common problems in all of them that can be addressed with a common strategy. An important question that this presentation tries to answer is the ICT profile of Latin America: consumer or producer. Data from the World Bank on ICT infrastructure and from the academic sector on the actual situation of the R&D activities in the region are analyzed to answer this question.

The article "Spatial clustering of dengue cases during the 2024 epidemic in Brazil" published in the Journal of Travel Medicine explores the spatial distribution of dengue cases in Brazil during the severe 2024 epidemic. The study reveals significant spatial heterogeneity in dengue incidence rates, with clusters primarily in the South and Southeast regions. Lower coverage rates of primary healthcare and family health teams were associated with higher dengue incidence, highlighting the importance of robust healthcare systems in controlling vector-borne diseases. The findings emphasize the need for targeted public health interventions, including enhanced vector control, infrastructure improvements, community health education, and strategic vaccine distribution, to reduce the burden of dengue in Brazil.
