Análise da imagem digital para estimativa da área foliar em plantas de laranja Pêra

Objetivou-se, com o trabalho, avaliar dois métodos de estimativa da área foliar, em plantas de laranja Pêra, pela análise da imagem digital obtida com scanner e câmera fotográfica digital. Para determinar a área das folhas, um grupo de discos foi colocado sobre um leitor de scanner, sendo que a imagem obtida foi armazenada. Os mesmos grupos de discos foram fixados sobre cartolina branca e fotografados com câmera fotográfica digital. As imagens obtidas da câmera fotográfica e do scanner foram processadas utilizando ferramentas de um editor de imagem que permite a contagem de pixels de determinada cor, no caso verde. Para a comparação dos métodos, os discos foram submetidos a integrador óptico de área foliar modelo LICOR-3100, utilizando os mesmos agrupamentos. Foram coletadas 20 folhas (cinco em cada quadrante da planta) por parcela de um experimento para comparação de fertilizantes comerciais e doses de zinco, aplicados via foliar, em plantas de sete anos de idade. O experimento foi composto de sete tratamentos e quatro repetições, num total de 28 parcelas. Os dois métodos apresentaram alta correlação com a área estimada pelo integrador óptico de área, considerado como método de referência. O método da análise da imagem obtida com câmera fotográfica, na resolução de 5.0 megapixel, foi mais precisa quando comparada à área estimada pelo integrador óptico de área.

Longer wavelengths of light improve the growth, intake and feed efficiency of individually reared juvenile pikeperch Sander lucioperca (L.)

We tested the effects of monochromatic light on the specific growth rate (SGR), feed intake and feed efficiency (FE) of juvenile pikeperch, Sander lucioperca (L.). Pikeperch were reared individually for 42 days in aquaria covered with blue, green, yellow or red gelatin filters or white paper (control; n=5). Linear regression analysis indicated a significant positive effect of longer wavelengths of light on the condition factor (CF), FE and SGR. The final weight, SGR and CF were significantly higher in fish reared under red than under white light, and FE was better under green, yellow and red light than under white light (Dunnett's post hoc test, P < 0.05) while blue was comparable to white light in terms of the measured parameters. After the growth trial, the spectral sensitivity of photoreceptor cells in the retina was tested using microspectrophotometry, which revealed the presence of rods with lambda(max) at ca. 530 nm and two cone classes, absorbing maximally at ca. 535 and 603 nm, all containing a porphyropsin-based pigment. These results suggest that the presence of mid and long wavelength-sensitive cones enhances visual sensitivity under mid-wavelength and long-wavelength environments, and thus supports the finding that longer wavelengths of incoming light can improve FE and SGR of the cultivated pikeperch.

Scientific collaboration network among Brazilian universities: an analysis in Dentistry area

This paper analyses the scientific collaboration network formed by the Brazilian universities that investigate in dentistry area. The constructed network is based on the published documents in the Scopus (Elsevier) database covering a period of 10 (ten) years. It is used social network analysis as the best methodological approach to visualize the capacity for collaboration, dissemination and transmission of new knowledge among universities. Cohesion and density of the collaboration network is analyzed, as well as the centrality of the universities as key-actors and the occurrence of subgroups within the network. Data were analyzed using the software UCINET and NetDraw. The number of documents published by each university was used as an indicator of its scientific production.

Cuestiones en torno a la transferencia de la custodia de los documentos entre archivos públicos

This paper discusses the different forms and conditions of incorporating collections from the judiciary by executive bodies. For such, we use the custodial history of the Juízo de Órfãos de São Paulo archives as a reference. An instance of the Brazilian justice between the 16th and 20th centuries, the Juízo de Órfãos de São Paulo is currently fragmented in several institutions of custody and under different denominations. Similarly, other archives from judiciary bodies underwent similar processes for custody transfer. However, this type of situation is not restricted to the past: nowadays, even under legally established norms and guidelines for the implementation of document management programs, it is still possible to find, recurrently, the adoption of similar procedures for the incorporation of collections. We therefore intend to establish a parallel between these two moments and the Brazilian archival legislation in force.

Professores e pesquisa: da formação ao trabalho docente, uma tessitura possível

This paper is the result of a research called Pedagogic Research in Education Schools: Aspects of the Work Conducted by Teachers developed at the post-doctorate training level at Fundação Carlos Chagas. It proposes a reflection on the concept of research that seeks to define and clarify their specific features, and brings about some of the differences that define the university, the school and the pedagogic researches, indicating the relevance of the last one in the teachers’ training process. The relationship between research and teachers’ training is highlighted as well as the need of a curricular restructuring in Education courses , in order to think research as a forming axis in teachers’ formation. Furthermore, the contributions of research in the teaching formation and practice is addressed, along with the study of school daily activities, focused on the necessary moment to put the assumptions underlying teachers’ practices into practice and also to experience socialization among students, teachers and other professionals in this field of knowledge.

A dor e o sofrimento em Hegel: os não-verbetes da Enciclopédia

This paper searches to present Hegel’s understanding of pain and suffering. It was taken as source of investigation Hegel’s Encyclopedia of Philosophical Sciences in which pain and suffering are also considered. The fi rst step was to identify the references of pain and suffering in the original text, i.e., in German and then compared with the Portuguese translation here used. The analysis followed the sequence of Hegel’s text as it mentioned the terms pain and suffering. It can be said that for Hegel pain and suffering are posed by the rational man according to the historical determinations and the relations that are established. So, there is no meaning in pain and suffering themselves but only through the relations that they create and create them as well. Neither the empirical manifestation nor the interpretation can resume the all meaning that pain and suffering may have. The totality of empirical and interpretative approaches reveals the full signifi cance of pain and suffering that can be seen in the human.

Recordações de um fragmento da história da imigração japonesa no Brasil

This paper proposes to investigate a specific fragment of the history of Japanese immigration to Brazil: labor relations during the period before the outcome of World War II. To this end, choosing oral history as a research method, and assumptions of historical materialism as a theoretical framework, we sought to examine the accounts of experiences remembered by a group of elderly women in this community of immigrant settlers. Theys participated both in the São Paulo coffee work in the first decades of the twentieth century, as the planting of cotton, in the 1930s.

O programa Bolsa Família: comparação entre as regiões Nordeste e Sudeste

This paper has as goal to analyze the Bolsa Família program in its several aspects (creation, discussions about it, perspective of those who receives the program benefits, its reach and effectiveness in comparison with what had been idealized by its creators). Besides that, it is done a report since the colonization age until the period before the creation of the social assistance programs to justify the inequality that the country are currently in, and, like it is made clear during the mentioned research, it has been improved in the course of years. And finally, it is proved through statistics the inequality between Northeast and Southeast regions. They represent, together, the biggest part of Brazilian population e their socioeconomics problems, in a way that can be taken into consideration as an example to the rest of the country

Avaliação dos gases de efeito estufa a partir do carvão

This paper addresses the context of emissions of Greenhouse Gases (GHG) from activities related to Coal, called fugitive emissions. The survey of factors, development, analysis, and suggestions for controlling emissions are conducted in order to reduce risks to the environment and people around it. The greenhouse gases absorb radiation, emitted by the Earth’s surface, and hinder their escape into space. This process is essential to terrestrial life. Increasing the concentration of those gases in the atmosphere has led to an increase in the terrestrial temperature. A selection of processes that emit gases and the study and development of calculations for measuring fugitive emissions applied in different sources from coal are performed. The greenhouse gases can be released from the extraction, processing, storage, and transportation of fossil fuels to the end consumer. Coal has 4 main fugitive factors: mining, post-mining, oxidation at low temperature, and uncontrolled combustion. The coal formation process produces methane (CH4) and carbon dioxide (CO2), being the methane, the main greenhouse gas from the coal mining and handling. The types of activities and the weight of each in the issuing process are observed. It is also made comparisons between the countries with the highest emissions rates. Are evaluated what has been done and what is needed to decrease emissions, for example the use of gas as an alternative fuel for energy generation

Neuróbica, ginástica para o cérebro: levantamento do atual estado da arte deste tema

This paper presents a brief review of theoretical studies on the stimulation and brain development. We also addressed questions about its plasticity, its influence on learning and behavior of the individual in interaction with the environment. Studies clearly show that the brain does not go into decline as we age. In this sense, a new discovery in neuroscience has revealed that the brain maintains the ability to grow and change the pattern of its connections to death. Findings such as these form the basis of neurobics. Demonstrating the importance of a relevant application of appropriate stimuli to change the morphology and function of neurons, the technique can be applied in different ways, ie, clinical, behavioral and neurological. Furthermore it can be applied during all phases of human development

A experiência do orçamento participativo em Campinas sob a ótica da comunicação pública

This paper analyzes the experience of Participatory Budgeting (PB) in the city of Campinas (SP) from the perspective of public communication, understand it as an important factor to increase the participation of social actors in decision-making processes. The democratization process in Brazil was the springboard for a change in the relations between state and society. In line with the new democratic demands, the OP appears to be the possibility of linkage between representative democracy and participatory democracy. As methodological procedure was used the case study of OP in Campinas from 2001 to 20011, comparing the administrations of two different political parties: PT (2001-2004), under the governments of Antonio da Costa dos Santos and Izalene Tiene, and PDT, with the consecutive term of Hélio de Oliveira Santos (2005-2011). We sought to assess whit this research if the communication actions used by different public administrations achieve the public interest adequately, encouraging popular participation
