Giberelina, citocinina e auxina na qualidade química de bagas de uva superior seedless

Trials were carried out in Juazeiro, Bahia State, Brazil, aiming to test plant regulators composed by gibberellin, cytokine and auxin effects on chemical quality of Superior Seedless grape berries. The first trial studied the effects of Stimulate (R) (bio regulator) and X-Cyte (R) (cytokine) associated to a new gibberellin formulation (N-Large (R)) and associated to Pro-Gibb (R), which is a product used as source of gibberellin. Products were sprayed at berries development phase (18, 21, 51 and 56 days after spur-pruning). Treatments were: T1: Pro-Gibb (R); T2: Stimulate (R) (Dose 1); T3: Stimulate (R) (Dose 2); T4: Stimulate (R) (Dose 3); T5: Pro-Gibb (R) + X-Cyte (R) (Low Dose - DB); T6: Pro-Gibb (R) + X-Cyte (R) (Intermediate Dose - DM); T7: Pro-Gibb (R) + X-Cyte (R) (High Dose - DA); T8: N-Large (R); T9: N-Large (R) + X-Cyte (R) (DB); T10: N-Large (R) + X-Cyte (R) (DM); T11: N-Large (R) + X-Cyte (R) (DA). The second trial aimed to assess the effect of the new gibberellin formulation (N-Large (R)) associated or not with cytokine (X-Cyte (R)) also sprayed straight over the bunches at berries development phase (17, 55 e 66 days after spur-pruning). Treatments were: T1: Pro-Gibb (R) - blank; T2: N-Large (R) (DB); T3: N-Large (R) (DM); T4: N-Large (R) (DA); T5: N-Large (R) (DB) + X-Cyte (R) (DB); T6: N-Large (R) (DB) + X-Cyte (R) (DM); T7: N-Large (R) (DB) + X-Cyte (R) (DA); T8: N-Large (R) (DM) + X-Cyte (R) (DB); T9: N-Large (R) (DM) + X-Cyte (R) (DM); T10: N-Large (R) (DM) + X-Cyte (R) (DA); T11: N-Large (R) (DA) + X-Cyte (R) (DB); T12: N-Large (R) (DA) + X-Cyte (R) (DM); T13: N-Large (R) (DA) + X-Cyte (R) (DA). Experimental design was random blocks with four repetitions with each repetition/parcel having three useful plants in the same row. At harvest, when bunches average had soluble solids over 15 degrees Brix, berries were collected for soluble solids, pH, titratable acidity analysis as well as (SS/AT) ratio calculation. In both trials, plant regulators evaluated did not provide significant changes on chemical quality of 'Superior Seedless' grape berries. Therefore, the lack of differences on response between the commercially used product (Pro-Gibb (R)) and the other products tested (Stimulate (R), X-Cyte (R) e N-Large (R)) prove the last as promising for the ` Superior Seedless' grape cultivation, leaving a larger range of alternative for grape farmers in the Sao Francisco Valley, Bahia.

Cálculo K: uma abordagem alternativa para a relatividade especial

In this paper we present an alternative approach due to Bondi for the special theory of relativity. During the development, we analyse the Bondi diagrams, visual resources from which we can take some information about the analysed systems, and we discuss the K factor of Bondi's theory, which is in the core of this work. We then discuss some of the main results obtained from Einstein's special theory of relativity such as the time dilation, spatial contraction and simultaneity of spatially separated events, besides the Lorentz transformations. We also show other two important results in physics coming from K calculus: the relativistic linear momentum and the total relativistic energy.

Estudo de um método automatizado para o cálculo da profundidade de visualização dos equipamentos de ultrassonografia

Ultrasound is the term that describes the sound waves with higher frequencies than human hearing. Ultrasound used in medical diagnosis is a modality based on the use of sound energy and the acoustic properties of the various parts of the body to produce images of stationary and moving tissues. However, despite the ease of use and security that this modality offers for not using ionizing radiation, one should ensure the accuracy and optimum performance of the equipment, which results in precise diagnoses. To accomplish that, periodic quality control tests must be performed, which include: physical and mechanical inspection of the equipment, image uniformity, depth of penetration/visualization, accuracy of distances, axial and lateral resolution, dead zone and doppler sensitivity. This work intends to study a computerized method for calculating the depth of penetration of ultrasound, comparing it to the observerdependent method currently used. The images were collected during the quality control tests of ultrasound equipment. The results of the comparison between the visual and computerized methods were not conclusive for selecting the safest methodology for obtaining the depth of visualization

Cálculo das funções de anisotropia e radial de dose para braquiterapia com semente de 192Ir em diferentes materiais de interesse em radiologia com o auxílio do programa baseado no método de Monte Carlo MCNPX

The brachytherapy braquiterapia is an x-ray modality radiotherapy in which stamped or halfstamped radioactive sources in format of seeds are used, wires or to one short distance, in contact or implanted to the fabric to be treated. All the treatment modalities require a previous planning. The formalism recommended for calculation of dose was considered by the AAPM for the first TG-43 Report. In it distributions of dose of isolated seeds measured and calculated by Monte Carlo method in water instead of with models half-empiricists. In this work we in accordance with present some preliminary results of the calculation of functions of radial anisotropy and of dose in the distance for seed of 192Ir, wide used in brachytherapy treatments of high tax of dose (HDR), with the aid of the program based on the Monte Carlo method MCNPX v2.50 (Mount Carlo N ParticleeXtended). The materials chosen in the simulation beyond water, had been MS20 and estriado muscle

Atividades exploratório-investigativas em sala de aula de cálculo I com uso de tecnologia

This study presents the results from a qualitative resource, based on research-action methodology, which examined the innovate teaching practices implementations in the Calculus I during 2011 year. The analysis of collected data from three used sources – an initial questionnaire, an exploratory-investigative classroom, and an interview with some students at the end of the second semester – reveals that the students had appropriated of the technological recourses, using it as a tool to look for the knowledge. The investigative activities with the use of information technologies made the use of multiple representations in solving mathematical tasks, making the transition of numerical, algebraic and geometrical results possible for the students when they have looking for validation of their hypotheses and conjectures during mathematical problems solving. This works helped in the insertion of new practices in the discipline, and their results validate the proposal presented by the teacher, which is the discipline of Calculus use, whose character is strongly linked to the training content of the student, as a discipline whose can contributed to the pedagogical formation of the graduation student, leading him to know the Mathematical Education possibilities, specially the Mathematical Investigation - Solving Problems, in the outlook of dialogued classes where the teacher assumes the facilitator role and where the students become actives in their pursuit of knowledge

Análise da influência do torque de montagem na resistência de parafusos de fixação

Whereas the assembly torque calculation has great importance on efficiency and life of bolts, the objective of this study was to analyze the combined stresses during assembly, the friction coefficient, compare the rupture torque results with the indicated torques by standards and to present a new torque method without the stress combination (shear stress and normal stresses). For this study were carried eighteen tests with different diameters and materials, this bolts were undergoing five ranges torque until the breaking torque. With the experimental rupture torque values for each test and with the bolt quality certificate was possible to calculate the friction coefficient so compared with the theory. Another comparison was the experimental rupture torque with assembly torque indicated by NBR-8800 and ASME-PCC. The main conclusion are related to combined stress, because for this factor can fail at the assembly time, so for in some cases must use the tensioning method, because in this method won't be present torsional stresses

Professores em formação: o momento da prática de ensino e a relação entre estagiários e professores-colaboradores

O tema Prática de Ensino, Estágio Curricular Supervisionado tem sido discutido na literatura brasileira desde o século XX, ora criticando-se a Didática, ora questionando-se a Formação dos Professores. Observa-se que não há nas políticas públicas menção sobre a formação do professor-colaborador com relação à sua preparação ou orientação, constituindo-se no problema desse estudo. Parte-se do pressuposto de que “a teoria da formação que fundamenta a prática pedagógica do professor da Educação Básica não é a mesma que fundamenta a formação inicial na universidade” e/ou que “a falta de um projeto mais amplo da formação dos formadores impedem um trabalho independente e mais objetivo”. Dessa forma objetiva-se: (a) averiguar a concepção que os estagiários têm de escola, socialização profissional e estágio no processo de aquisição da experiência de ensino por ocasião da implementação da Prática de Ensino, considerando como temas centrais a passagem de estudante-estagiário a professor-principiante; (b) identificar nos relatórios de estágio as dificuldades assinaladas, bem como as descobertas relativas à docência no que concerne aos estágios e (c) analisar as concepções que os professores das escolas se utilizam para orientar, formar e avaliar os estagiários durante o processo de estágio. Na busca dos resultados escolheu-se a pesquisa de natureza qualitativa, do tipo construcionismo social, tendo na fonte documental, na entrevista semi-estruturada e na análise de conteúdo as técnicas escolhidas. No que tange aos estagiários, encontramos que estes, no momento em que entram em contato com a prática profissional, sentem insegurança e dificuldades com relação ao fazer pedagógico. Com relação aos professorescolaboradores, observamos que há a necessidade de uma formação neste sentido, dessa forma, encontramos... (Resumo completo, clicar acesso eletrônico abaixo)

Determinação de comunidades em redes biológicas integradas

To understand how biological phenomena emerge, the nonlinear interactions among the components envolved in these and the correspondent connected elements, like genes, proteins, etc., can be represented by a mathematical object called graph or network, where interacting elements are represented by edges connecting pairs of nodes. The analysis of various graph-related properties of biological networks has revealed many clues about biological processes. Among these properties, the community structure, i.e. groups of nodes densely connected among themselves, but sparsely connected to other groups, are important for identifying separable functional modules within biological systems for the comprehension of the high-level organization of the cell. Communities' detection can be performed by many algorithms, but most of them are based on the density of interactions among nodes of the same community. So far, the detection and analysis of network communities in biological networks have only been pursued for networks composed by one type of interaction (e.g. protein-protein interactions or metabolic interactions). Since a real biological network is simultaneously composed by protein-protein, metabolic and transcriptional regulatory interactions, it would be interesting to investigate how communities are organized in this type of network. For this purpose, we detected the communities in an integrated biological network of the Escherichia coli and Saccharomyces cerevisiae by using the Clique Percolation Method and we veri ed, by calculating the frequency of each type of interaction and its related entropy, if components of communities...
