Authors: Alves Danielle Conte , Ugá Maria Alicia Dominguez , Portela Margareth Crisóstomo
Published: August 2016

Resumo Introdução Trata-se de estudo de caso que teve como objetivo explorar a associação entre ações de promoção da saúde e prevenção de doenças cardiovasculares (DC) desenvolvidas por uma operadora de plano de saúde brasileira que adotou a Estratégia Saúde da Família, a utilização de serviços e os respectivos custos. Métodos Foram selecionados os beneficiários com idade maior ou igual a 30 anos, cadastrados nos programas até 31 de dezembro de 2004 em duas capitais. Foi realizada a descrição do perfil demográfico e dos fatores de risco para DC, bem como a avaliação do perfil de utilização de serviços e dos custos, entre 2004 e 2007. Resultados Verificou-se a redução do número médio de consultas por beneficiário e do custo médio com essas consultas no grupo cadastrado. O número de exames per capita aumentou, elevando esses custos. Em Curitiba, no Paraná, ocorreu aumento do número médio de internações por beneficiário e do custo médio, enquanto, em Goiânia, Goiás, ocorreu redução desses números. Conclusão Considerando que cerca de 25% da população brasileira possui plano de saúde, torna-se relevante incentivar a realização desses programas, em consonância com as políticas empreendidas pelo Ministério da Saúde (MS), além de avaliar a utilização dos serviços e os resultados na saúde dos indivíduos.

ABSTRACT Objective: to analyze the support for learning, in the perspective of patient safety, offered in the work environment, according to health professionals working in primary care. Method: a transversal study, held with 86 health professionals working in primary care. A validated instrument was used, applied via the Internet. Descriptive statistical analysis was undertaken with a presentation of median, mean, standard deviation and coefficient of variation. Results: points which are favorable to supporting learning were evidenced, such as mutual respect, autonomy for organizing the work and valorization of new ideas, which obtained means above 7.0. The variables which hinder the process of learning in the work environment, perceived by the professionals, were: resistance to changes, and excess of work impeding reflection on how to improve the work, with means above 6.0. Conclusion: the study found evidence of indicators related to the process of staff development in the area of health and indicates the influence of support for learning for the improvement of the work processes and of patient safety. It is necessary that a culture involving the systematic assessment of educational interventions in health should be established, the aim being to diagnose actions which are more incisive for changing health professionals' attitude and, therefore, clinical practice.

Published: August 2016

Abstract Introduction The correct use of glass fiber posts in endodontically treated teeth is essential for the clinical success of restorative treatment. Objective This study evaluated the push-out shear bond strength of relined (R) or non-relined (NR) glass fiber posts, cemented with self-adhesive resin cement [RelyXTM U100 (U100)] and conventional resin cement [RelyXTM ARC (ARC)]. Material and method Sixty human single-rooted teeth were endodontically treated and divided into ARC-NR; U100-NR; ARC-R; U100-R groups. The teeth were sectioned into cervical, middle and apical thirds, and subjected to the push-out test. Bond strength was analyzed by the Friedman test; cement and post types were compared by the Mann Whitney test. The pattern of failures was evaluated with digital camera through images at 200x magnification, and was classified as adhesive (at the cement/dentin or cement/post interface), cohesive (cement or post), and mixed failures. Result In ARC-NR, bond strength values were higher in the cervical third; in U100-NR and ARC-R they were similar between the thirds. In U100-R, in the cervical and middle thirds the bond strength values were similar, and there was lower value in the apical third. For non-relined glass fiber posts, the highest mean bond strength values were observed with self-adhesive resin cement. Whereas, relined posts cemented with conventional resin cement had stronger cement layer in comparison with non-relined fiber posts. Conclusion The post relining technique was efficient in ARC-R. ARC-NR and U100-R showed improved bond strength in the cervical region of canal walls. The main failures were adhesive at the cement-post interface.

Published: August 2016

Abstract This study aimed to verify the determinants of goodwill impairment (GOODWIMP) loss recognition in Brazilian companies. For this, a descriptive and documentary study was carried out in which information was collected from databases and explanatory notes using a quantitative approach. The study sample was comprised of Brazilian companies listed on the Thomson database, totaling 91 companies and 346 observations. Data were collected from 2011 to 2014. For the treatment and analysis of the data, logistic regression with panel data was used. The results show that the factors change in management (CHMAN), book-to-market (BM), number of cash generating units (CGU), variation in return on assets (ΔROA) and goodwill (GOODW) were significant in determining GOODWIMP losses. These findings indicate that in addition to economic factors, managers' actions are associated with the recognition of such losses, which can be characterized as incentives for earnings management (EM) practices. Therefore, it is generally concluded that the GOODWIMP losses recognized in the companies analyzed may not only have been used to reduce their assets to recoverable amounts, but also to achieve results consistent with the objectives of managers.
L. S. Vigotski e o ensino de arte: "A educação estética" (1926) e as escolas de arte na Rússia 1917-1930
Authors: Wedekin Luana Maribele , Zanella Andrea Vieira
Published: August 2016

Resumo Problematizam-se, neste artigo, as relações entre "A educação estética" (1926), de Lev S. Vigotski, e o contexto de reestruturação da educação e do ensino das artes após a Revolução Russa de outubro de 1917. Trata-se de pesquisa bibliográfica que operou um diálogo entre Vigotski e os historiadores que estudaram as escolas de arte anteriores e posteriores à Revolução de 1917. Orientaram as análises as seguintes questões: as ideias de Vigotski sobre estética estavam em consonância com as práticas estabelecidas nessas novas instituições? Como essas ideias se relacionavam com as políticas para o ensino de arte no período? Constatou-se que "A educação estética" foi forjada na experiência prática de Vigotski em diálogo com a arte e a ciência de sua época, pautada em pensamento independente dos encaminhamentos oficiais, mas cuja qualidade das reflexões e dos princípios garante a atualidade e a potência da obra para pensar o ensino de arte hoje.
Apelo ao consenso e impossibilidades da retórica: o caso do XI governo constitucional português
Authors: Lopo Teresa Teixeira
Published: August 2016

Resumo Neste artigo analisa-se como se formulou o apelo ao consenso no discurso pedagógico oficial do XI governo constitucional português, considerando os valores orientadores do processo de decisão e as crenças associadas ao impacto da política educativa e os seus resultados, em termos dos consensos alcançados na relação com os partidos políticos com representação parlamentar. Verificou-se ter sido uma construção retórica feliz do discurso, a desencadear, para além da concordância naturalmente pressuposta como consenso de base com o partido que apoiava parlamentarmente o governo, uma disposição para a ação dos outros partidos políticos com representação parlamentar. Tratou-se, contudo, de um consenso possibilitado pela ambivalência característica entre a convicção e a persuasão que se associa a qualquer consenso obtido por meios retóricos e não de decisões de motivação racional originadas por um discurso pedagógico oficial convincente.

Published: August 2016

Resumo Este artigo relata, a partir de pesquisa empírica, como estudantes de 4° ano do Ensino Fundamental configuram o poético, por meio do estudo orientado de poemas veiculados em obras selecionadas pelo Programa Nacional Biblioteca da Escola (PNBE). Parte de investigação maior, o artigo propõe procedimentos mediadores para o poema "O eco", de Cecília Meireles, problematizando o letramento poético. A investigação apoia-se principalmente em Huizinga e Kirinus. O problema posto justifica-se em virtude de a formação de leitores ser um desafio para o âmbito educacional e para a criação e a manutenção de políticas públicas. O artigo contribui para apresentar possibilidade de inserção escolar do acervo do PNBE e aponta caminhos para o desenvolvimento do poético, que tende a ser pouco explorado na escola.

Published: August 2016

Abstract This study aimed to evaluate the plant growth regulator application, in different doses, on priming, with and without water restriction, in corn seeds. Evaluations were carried out in two periods (0 to 30 days of storage), with treatments consisting of seeds primed in water (0.0 MPa) and polyethylene glycol 6000 solution (-0.4 MPa), with or without plant growth regulator added in different doses, plus a control group. The amount of plant growth regulator was standardized by the gibberellic acid concentration in the commercial product, adopting the doses zero, 1, 2 and 3 mg of gibberellic acid. L-1 solution. After priming, the seeds were dried in an oven with forced air circulation for nine hours, and evaluated for water content, percentage and first count of germination, percentage of abnormal seedlings and non-germinated seeds, cold test, seedling length and dry weight and vigor index. Priming with water restriction -0.4 MPa, in solution of polyethylene glycol 6000, improves the vigor; however, the addition of plant growth regulator in priming does not provide increase in corn seeds quality. Corn priming in water, regardless the addition of plant growth regulator, reduces the ability of the seeds to withstand storage.

RESUMO Introdução A Estimulação Cerebral Profunda tem sido considerada uma intervenção satisfatória para os sintomas motores cardinais da doença de Parkinson, porém ainda há poucas evidências sobre seu impacto na comunicação. Objetivo Esse trabalho teve como objetivo caracterizar os seguintes aspectos da comunicação: cognição, linguagem, fala, voz, e autopercepção de dois pacientes com doença de Parkinson em situação pré e pós a cirurgia de implantação da Estimulação Cerebral Profunda. Método Os pacientes foram avaliados através de: um teste de rastreio cognitivo; uma avaliação breve da linguagem; um protocolo autodeclarado e aspectos da voz e da fala, que foram avaliados por um fonoaudiólogoexpertna área e cegado para o estudo. Resultado Observou-se no momento pré-cirurgia que o Caso I apresentava comprometimento nos aspectos cognitivo, da linguagem e voz, enquanto que o Caso II apresentava alteração apenas na voz. A avaliação pós-cirúrgica dos casos mostrou um padrão oposto de efeito da Estimulação Cerebral Profunda, quando analisados os dados pós-cirúrgicos, referente à comunicação. O Caso I, que era considerado com o maior prejuízo no período anterior à cirurgia, apresentou melhora em alguns aspectos, enquanto o Caso II, que era observado com menos prejuízo comunicativo previamente à cirurgia, apresentou piora em outros aspectos. Conclusão Este estudo demonstrou que a Estimulação Cerebral Profunda pode influenciar diferentes aspectos da comunicação, tanto de modo positivo quanto negativo, e que é necessário investigar fatores associados aos diferentes efeitos causados pela Estimulação Cerebral Profunda sobre a comunicação dos pacientes com doença de Parkinson.

Abstract OBJECTIVE To identify, within a multidisciplinary team, the facilitating and hindering aspects for teamwork in a coronary care unit. METHOD A descriptive study, with qualitative and quantitative data, was carried out in the coronary care unit of a public hospital. The study population consisted of professionals working in the unit for at least one year. Those who were on leave or who were not located were excluded. The critical incident technique was used for data collection, by means of semi-structured interviews. For data analysis, content analysis and the critical incident technique were applied. RESULTS Participants were 45 professionals: 29 nursing professionals; 11 physicians; 4 physical therapists; and 1 psychologist. A total of 49 situations (77.6% with negative references); 385 behaviors (54.2% with positive references); and 182 consequences emerged (71.9% with negative references). Positive references facilitate teamwork, whereas negative references hinder it. A collaborative/communicative interprofessional relationship was evidenced as a facilitator; whereas poor collaboration among agents/inadequate management was a hindering aspect. CONCLUSION Despite the prevalence of negative situations and consequences, the emphasis on positive behaviors reveals the efforts the agents make in order to overcome obstacles and carry out teamwork.
Policies for control and prevention of infections related to healthcare assistance in Brazil: a conceptual analysis
Authors: Oliveira Hadelândia Milon de , Silva Cristiane Pavanello Rodrigues , Lacerda Rúbia Aparecida
Published: August 2016

Abstract This article is a theoretical-reflexive study that aims to discuss the development and changes in the quality of healthcare assistance to the patient over the years in Brazil, in light of the policies of control and prevention of Healthcare-associated Infection (HAI). Aspects of HAI and the process of change in health policy in Brazil, as well as the quality of assistance associated with its control, are approached in relation to policies of patient safety. There are various new theoretical and practical proposals created in Brazil. In spite of the difficulty of measuring patient safety, directed to the prevention and control of HAI, we emphasize that to only create policies and establish norms, guidelines, and indicators is not sufficient. If no structural support or conditions exist for interventions in the practices of healthcare professionals, aiming at results in acceptable levels, the control of HAI will not be achieved.

¿PUERTAS ABIERTAS? migrações regionais, direito e integração na Comunidade Andina de Nações e no Mercosul
Authors: Mendes José Sacchetta Ramos
Published: August 2016

O Mercosul e a Comunidade Andina de Nações estabeleceram, nas últimas décadas, legislações comunitárias sobre as migrações regionais e os migrantes. Os dois blocos foram instituídos a partir de metas de integração comercial e, posteriormente, agregaram temas sociais a seus objetivos. Este artigo apresenta o desenvolvimento normativo realizado nos processos sul-americanos de integração, em sua busca por soluções para a problemática dos deslocamentos humanos provindos de países vizinhos. Apesar dos avanços, subsistem obstáculos políticos e legais à regularização da condição dos migrantes e ao seu acesso a direitos sociais. Entre as razões apontadas, está o desalinhamento de normas internas dos países em relação aos acordos multilaterais e a pequena participação das sociedades sul-americanas na tomada de decisões. No artigo, comenta-se a adoção de princípios gerais fundamentados no respeito aos Direitos Humanos e a via de inclusão da migração e dos migrantes no projeto de uma cidadania regional.

Published: August 2016

Objective

To describe the temporal pattern of otitis media with effusion (OME) resolution for a cohort of nonsyndromic cleft palate children enrolled before palatoplasty and followed through 5 years of age.

Design

This is a prospective, longitudinal study of the time course for OME resolution in infants and children with palatal clefts.

Setting

Cleft Palate Craniofacial Center of a tertiary care pediatric hospital.

Participants

This study included 52 children with cleft palate (29 boys, 45 white, Veau 1 through 4) who had a Furlow-type palatoplasty between 10 and 24 months of age performed by one of six surgeons.

Interventions

Standard cleft palate management was supplemented with study visits to the research clinic pre- and postpalatoplasty and then yearly to 6 years of age for assessments of middle ear status by interval history, otoscopy, and tympanometry.

Main Outcome Measure

The main outcome measure was age at otitis media resolution defined as the age in years at the first in a sequence of “disease-free” diagnoses not interrupted or followed by any other diagnosis.

Results

The cumulative percent OME resolution for ears/children at ages <1, 1, 2, 3, 4, 5 years was 4.1/4.4, 14.3/10.9, 31.6/21.7, 45.9/37.0, 56.1/50.0, and 70.4/60.9%. OME resolution followed a simple linear time curve with slopes of 13.5% (confidence interval [CI] = 12.2% to 14.8%, r2 = .99) and 11.9% (CI = 10.1% to 13.6%, r2 = .99) resolutions per year for ears and children, respectively.

Conclusions

There is a natural, age-related pattern of resolution for persistent OME that affects most infants and young children with cleft palate that is not affected by palatoplasty.
Triclopyr Application Timing and Concentration Influence Low-Volume Basal Bark Efficacy on Chinese Privet (Ligustrum sinense)
Authors: Enloe Stephen F. , O'Sullivan Sarah E. , Loewenstein Nancy J. , Brantley Eve F. , Lauer Dwight K.
Published: August 2016

Chinese privet is an invasive shrub that commonly infests roadsides and bottomland forests across the southeastern United States. Its aggressive growth and ability to prolifically sprout from the root collar and shallow lateral roots makes control very difficult. Individual plant treatment methods such as low-volume basal bark herbicide application with triclopyr are commonly used for Chinese privet control. However, little research has been done to examine optimal triclopyr concentrations and application timings for the low-volume basal bark method. Furthermore, little is known regarding basal bark treatment efficacy when plant size varies. To address these questions, field studies were conducted from 2009 to 2011 at two locations in east-central Alabama near Auburn and Opelika. The triclopyr butoxyethyl ester formulation was applied in January or March to Chinese privet shrubs across a range of sizes in a commercially available basal oil carrier at 24 (5% v/v−1), 48 (10% v/v−1), and 96 g L−1(20% v/v−1). Additionally, a triclopyr butoxyethyl ester ready-to-use formulation (90 g L−1) was applied at 100% v/v−1. Canopy defoliation, sprout height, and mortality were quantified at 6, 12, and 18 mo after treatment. Triclopyr at all concentrations was highly effective in defoliating Chinese privet and reducing height of new basal sprouts. However, mortality was concentration dependent. The 90 and 96 g L−1treatments resulted in 88 and 89% mortality across timings, while the 24 and 48 g L−1treatments resulted in 63 and 76% mortality. March applications were less effective as basal diameter increased, especially at the lower triclopyr concentrations where mortality fell to less than 40%. These results indicate that triclopyr is an effective treatment for Chinese privet control, but efficacy is influenced by concentration, application timing, and plant size.
Higher Tolerance to Abiotic Stresses and Soil Types May Accelerate Common Ragweed (Ambrosia artemisiifolia) Invasion

Published: August 2016

Common ragweed is a troublesome allergenic invader and noxious weed of several crops. Despite extensive research to understand the factors affecting its invasion, the role of environmental stresses and soil types on survival and growth is poorly understood. The objective of this study was to determine the effects of drought, salinity, and soil types on survival, growth, and nutrient uptake of ragweed in greenhouse experiments to predict its invasiveness in Turkey. Three separate experiments, with five drought intensities (100, 75, 50, 25, and 12.5% of field capacity [FC]), four levels of salinity (0, 3, 6, and 12 dS m−1), and five soil types varying in sand, silt, and clay content were performed. Severe drought and salinity levels reduced seedling survival, while soil type had no effect. Increasing drought and salinity negatively affected growth and nutrient uptake; the poorest growth was observed under severe drought intensity. Ragweed exhibited intensive tolerance to drought, even severe levels, while it tolerated salinity up to 6 dS m−1 for seedling survival. Growth was negatively affected above 3 dS m−1. The highest and lowest nutrient accumulations were recorded under moderate and extreme drought intensities, respectively. Similarly, the highest Na accumulation was observed under extreme saline conditions, whereas the highest P uptake and K/Na ratio were achieved under nonsaline conditions (0 dS m−1). Variation of soil texture had no effect on growth and nutrient uptake. The highest Ca, Mg, and Na accumulations were recorded on clay soil, while higher P accrued on sandy-loam soil. Increased tolerance of ragweed to severe drought and moderate salinity and its nonselective nature for soil type indicate that semiarid and partially arid regions in Turkey have plenty of vacant niches for ragweed invasion.

Authors: Chang Jun , Zhao Jiuye , Shang Xiaopeng , Yu Xin , Zhang Yangyang , Zhang Tingting
Published: August 2016

Ye'elimite-containing cements are of growing research interest owing to their characteristic properties. Strontium (barium) (Sr(Ba))-bearing ye'elimite is synthesised by the substitution of Sr2+(Ba2+) ions for Ca2+ ions in ye'elimite. Here, Rietveld refinement for Sr(Ba)-ye'elimite is reported. The effect of strontic and baric substitutions on the crystal system of ye'elimite is analysed. Additionally, the crystalline phases and potential ACn (amorphous and non-quantified crystalline phase) contents, in clinkers containing Sr(Ba)-ye'elimite, are determined. As substitutions increase, the crystal system of Sr-bearing ye'elimite transforms from an orthorhombic system to a cubic system, but Ba-bearing ye'elimite remains cubic throughout the process. In the clinkers, the Sr-bearing ye'elimite reaches 97% (wt%) and the Ba-bearing ye'elimite is greater than 94% (wt%), with insignificant amounts of amorphous and non-quantified crystalline phase (ACn) contents. With a higher degree of substitutions, the lattice parameters of Sr(Ba)-bearing ye'elimite exhibit linear growth trends.

Published: August 2016

Introduction: Currently, chronic kidney disease (CKD) is a major health problem and in the most severe conditions, kidney transplantation is an alternative treatment. However immunosuppression induced these patients to respiratory complications and endotracheal intubation. In order to assist the decision of the best time for weaning and extubation of these patients, there are predictive indexes that should be considered in preliminary assesment. Objective: To check the capacity of predictive indexes for weaning of mechanical ventilation, rapid shallow breathing index (RSBI), oxygenation rate (PaO2 /FiO2 ) and maximum inspiratory pressure (MIP) in predicting the success or extubation failure in kidney transplant patients. Methods: This study is a prospective cohort carried out with patients aged over 18, under mechanical ventilation for more than 24 hours. The patients were submitted to the Spontaneous Breathing Test, also the assessment of the Rapid Shallow Breathing Index, oxygenation index (PaO2 /FiO2 ), and maximum inspiratory pressure (MIP) and they were observed during 48 hours after to evaluate the success and extubation failure. Results: A total of 106 patients were eligible, and 20 of these were included with mean age of 46.9 ± 3.06 years and 14 of the subjects were male. Three patients showed extubation failure, and needed to have reintubation within the period of 48 hours as considered. Conclusion: The indices to predict weaning of mechanical ventilation, when within the expected normal values, seem to be able to predict extubation, with the exception of MIP that, even in cases of success, showed itself to be at levels lower than the predicted percentage.

The Alfred Wegener Institute operates two stations in Dronning Maud Land, Antarctica. The German overwintering station Neumayer III is located on the Ekström Ice Shelf at 70°40’S and 08°16’W and is the logistics base for three long-term observatories (meteorology, air chemistry and geophysics) and nearby research activities. Due to the vicinity to the coast (ca. 20 km from the ice shelf edge), the Neumayer III Station is the junction for many German Antarctic expeditions, especially as the starting point for the supply traverse for the second German station Kohnen.The summer station Kohnen is located about 600 km from the coast and 750 km from Neumayer III Station on the Antarctic plateau at 75°S and 00°04’E. It was erected as the base for the deep-drilling ice core project, which took place between 2001 and 2006. Since then Kohnen Station is used as a logistics base for different research projects.

Considerations about energy consumption in sensor nodes over wireless personal area networks using MiWi protocol
Authors: Meneses Benavides Gustavo
Published: August 2016

Adopting techniques to increase operation time of battery-powered sensor nodes in wireless networks is necessary when implementing practical monitoring applications intended to run over extended periods of time. Energy harvesting; DC-DC converter techniques; and features of modern microcontrollers like extreme lower consumption, Sleep and Idle states, can contribute to improve the performance of network nodes. Designers can also use the possibilities offered by special protocols for wireless sensor networks, routing algorithms, and data aggregation plus collection strategies. Issues related to the process of design and implementation of an energy-efficient sensor node operating under IEEE 802.15.4-compliant MiWi protocol from Microchip® Technology are presented. Operating tests were conducted in different hardware/firmware scenarios in order to verify the changes in node’s performance depending on the adopted configuration.

The objective of this project is to identify and adapt the best practices for the identification, specification, and validation of requirements that guide the software implementation and maintenance processes in applications of an electric company. We performed this identification through the study and analysis of the actual state of the topic in Colombia, particularly within electric companies and supported by the theoretical examples of requirements engineering. Both the examples and the methodological models identified as best practices —such as RUP, agile development (focused on Scrum), CMMI, use cases and use cases 2.0, PMI —focused on the management of the scope and stakeholders—, and BABOK support the understanding of this topic. The result is a process that collects models to improve the requirements for new developments and for the handling of change requests and incidents/emergencies, obtaining positive evaluations by expert judgement in a pilot experiment.

Android is an operating system which currently has over one billion active users for all their mobile devices, a market impact that is influencing an increase in the amount of information that can be obtained from different users, facts that have motivated the development of malicious software by cybercriminals. To solve the problems caused by malware, Android implements a different architecture and security controls, such as a unique user ID (UID) for each application, while an API permits its distribution platform, Google Play applications. It has been shown that there are ways to violate that protection, so the developer community has been developing alternatives aimed at improving the level of safety. This paper presents: the latest information on the various trends and security solutions for Android, and SafeCandy, an app proposed as a new system for analysis, validation and configuration of Android applications that implements static and dynamic analysis with improved ASEF. Finally, a study is included to evaluate the effectiveness in threat detection of different malware antivirus software for Android.

A dessecação é uma técnica utilizada pelos produtores de soja com o objetivo de antecipar a colheita. No entanto, para a produção de sementes essa técnica necessita de cuidados, uma vez que alguns dessecantes podem deixar resíduos na semente prejudicando sua qualidade. Objetivou-se com esse estudo avaliar o efeito da aplicação de dessecantes em diferentes épocas sobre a qualidade fisiológica de sementes, após seis meses de armazenamento, de cultivares de soja com diferentes teores de lignina no tegumento. As plantas das cultivares BRS Silvânia RR, BRS Valiosa RR, BRS 245 RR e BRS 247 RR foram dessecadas com os herbicidas Diquat, Paraquat e Glufosinato de amônio, e água como tratamento controle, aplicados quando as sementes apresentavam 30, 40 e 50% de teor de água. Após a colheita e beneficiamento, as sementes foram armazenadas por seis meses em armazém convencional. Para a avaliação da qualidade fisiológica das sementes foram realizados os testes de germinação, emergência, índice de velocidade de emergência, condutividade elétrica e tetrazólio. As sementes das cultivares BRS Silvânia e BRS Valiosa apresentaram menor qualidade fisiológica das sementes do que as cultivares BRS 245 e BRS 247. A dessecação, especialmente quando Glufosinato de amônio foi aplicado, mostrou-se mais prejudicial à qualidade fisiológica das sementes de soja do que os demais tratamentos.

No Brasil, a alface é a principal hortaliça produzida e comercializada, carecendo, contudo, de tecnologias para otimizar a produção e garantir a sustentabilidade ambiental em áreas agrícolas. Objetivou-se com este trabalho verificar o efeito de diferentes coberturas do solo no crescimento, produtividade de plantas de alface e na temperatura do solo. O delineamento experimental utilizado foi em blocos casualizados, com seis tratamentos e cinco repetições. Os tratamentos estudados consistiram de tipos de cobertura do solo, sendo: cobertura com material vegetal (CVe), polietileno preto (0,020 mm) (PPt), polietileno prata (0,020 mm) (PPr), polietileno branco (0,020 mm) (PBr), polietileno transparente (0,100 mm) (PTr) e solo sem cobertura (Testemunha - T). As variáveis analisadas foram: massa fresca total, número e massa fresca de folhas comerciais, massa fresca de raiz, diâmetro da cabeça e produtividade. Foi realizado o monitoramento da temperatura do solo durante toda condução da cultura. As coberturas com polietilenos prata, branco e preto foram estatisticamente iguais e superiores às demais coberturas para todas as características agronômicas avaliadas na alface. A temperatura do solo foi influenciada pelos tipos de cobertura. Em relação ao solo descoberto, a temperatura do solo aumentou nos tratamentos com coberturas plásticas, e diminuiu no tratamento com cobertura vegetal morta.

A clorose variegada dos citros (CVC) é uma doença de plantas cítricas, constatada, em 1987, inicialmente nos municípios do noroeste paulista e da região do triângulo mineiro. Ela é causada por uma bactéria de xilema, denominada Xylella fastidiosa. Sua disseminação ocorre através de borbulhas contaminadas ou por meio de insetos vetores da ordem Hemiptera e família Cicadellidae. Objetivou-se com este trabalho identificar as espécies de cigarrinhas vetoras da Xylella fastidiosa, bem como determinar a sua distribuição espaço-temporal em pomar comercial de laranja doce (Citrus sinensis (L.) Osbeck). O experimento foi realizado em um talhão comercial de laranja doce, variedade Pêra, enxertada sobre limão ‘Cravo’, localizado na região Noroeste do Paraná. Para a amostragem, foram utilizadas armadilhas adesivas amarelas, distribuídas na área periférica e central do pomar, com quatro repetições por rua amostrada (5ª, 30ª, 55ª e 80ª Planta), tendo cada planta sido considerada uma unidade amostral. Foram avaliadas dez ruas do talhão, totalizando 40 armadilhas por amostragem. A cada trinta dias durante o período de avaliação, as armadilhas foram renovadas no pomar. As principais espécies capturadas foram Acrogonia citrina e Dilobopterus costalimai. As maiores incidências ocorreram do inverno para a primavera e do verão para o outono do ano seguinte. De acordo com as análises geoestatísticas, a distribuição espacial dessas espécies se concentra na zona periférica da parcela, onde foi capturada a maior incidência de espécies. Os resultados revelam que há necessidade de adoção de práticas de manejo para as cigarrinhas vetoras de X. fastidiosa diferenciadas no espaço e no tempo.

O cultivo em ambiente protegido possibilita a produção de alface em condições limitantes para o seu desenvolvimento, principalmente relacionadas à precipitação e temperatura. O objetivo deste estudo foi avaliar o desempenho de cultivares de alface tipo americana sob cinco diferentes ambientes em condições de altas temperaturas. Foram avaliados vinte tratamentos no período de outubro a dezembro de 2011, empregando o delineamento experimental em blocos casualizados em esquema fatorial 4 x 5, sendo quatro cultivares de alface tipo americana (Lucy Brown, Tereza, Gloriosa e Graciosa) e cinco ambientes de cultivo (telas de sombreamento 30 e 50%, telas termorefletoras 30 e 50% e campo aberto), com quatro repetições. As médias de produtividade e massa fresca comercial variaram de 22,09 a 24,13 t ha-1 e 134,17 a 144,83 g planta-1, respectivamente, entre as cultivares. Os ambientes que proporcionaram as maiores médias foram as telas de sombreamento e termorefletora 50%. As cultivares de alface americana Teresa e Gloriosa são as mais indicadas para o cultivo em condições de alta temperatura, pois, entre as que apresentaram maior compacidade da cabeça, foram as que obtiveram menores comprimentos de caule e proporção da altura do caule dentro da cabeça, não sendo observada diferença entre as cultivares para a produtividade.
Bejelöltelek a Facebookon – közösségen kívüli közösséginek lenni
Authors: Boda Márton Attila
Published: August 2016

2014 decemberében a legnagyobb online közösségi oldalon, a Facebook-on végeztem kutatást, hogy egy közösség miként reagál egy ismeretlen személy bejelöléseire. Eleinte teljesen ismeretlen volt fiktív karakterem a Facebook-on bejelöltek számára, később pedig a közös ismerősök segítettek az ismerősi létszám növelésében. A bizalmat nagymértékben megalapozza, hogy milyen „referenciákkal” nyit felénk egy ismeretlen, hány közös ismerősünk bízott már meg benne. Kutatásom alapján a vizsgált csoportban úgy szereztem 1078 ismerőst, hogy közben 94,34%-ukkal semmilyen kommunikációt nem folytattam, és csak 3,34%-uk kérdezett rá, hogy honnét ismerik karakteremet. 3,49%-uk fel is köszöntötte az idegent vélt születésnapján, miközben a bejelöltek 79,12%-a elfogadta a bejelölést.

Property right acquisition from an unentitled person in the new Czech Civil Code
Authors: Petr Bohuslav
Published: August 2016

This article deals with the issue of property right acquisition from an unentitled person. It is in fact a breach of fundamental legal principle “nemo plus iuris ad alium transferre potest quam ipse habet”. Currently there is a great difference between decision practice of the Supreme Court of the Czech Republic on one side and decision practice of the Constitutional Court of the Czech republic on the other side. Whereas the Supreme Court of the Czech Republic insists on abovementioned traditional principle, the Constitutional Court of the Czech Republic allows breaching of this principle giving preference to a good faith of the acquirer. The new Czech Civil Code favors the conclusions of the Constitutional Court of the Czech Republic.

Authors: Tatárné Varga Ivett
Published: August 2016

To improve regional competitiveness with a special regard to large urban zones, and to support sustainable development, the analysis of possible methods and levels of cooperation is a key element.This study is the first publication of a detailed primer research survey conducted among city and regional level representations in the European Union, as part of extended external environmental analysis of municipal strategic planning. The survey and the analysis based on it concentrate on the role of municipal and regional EU representations is Brussels by introducing their main activities, the structure of their relations, their intra-state, extra-state and EU-level political activities. The analysis evaluates both potential possibilities of inter-regional cooperation and increasing of funding absorption, mainly in relation to direct EU funds.As maintaining or potential increase of funding absorption, financing, city and regional marketing are outstanding priorities of strategic planning, the study also introduces the present status of representations in these fields and their participation in EU-funded projects and also, it offers further areas to extend their strategic potential.
