Número de amostras na análise geoestatística e na krigagem de mapas de atributos do solo

The objective of this study was to analyze different intensities of soil sampling for accuracy in geostatistical analysis and interpolation maps for precision agriculture in the sugarcane area. Soil samples were collected at two regular grids at a depth of 0.00 to 0.20m for granulometric analysis (area 1) and soil fertility (area 2). We compared soil sampling intensities: 208, 105, 58 and 24 points in Area 1 and 206, 102 and 53 points in Area 2. The data were submitted to descriptive analysis and geostatistics. The variograms constructed with 105 points didn't differ from variograms with 208 points, which doesn't occur for 58 and 24 points. The increase of sampling interval and reducing the number of points promote greater error in kriging. Samples with more than 100 points per area did not result in significant improvements in the error of kriging, or differed in the amount of fertilizer applied to the field.

Perfil de pesquisa dos departamentos da Faculdade de Engenharia do Campus de Guaratinguetá

To know the profile of research of each Department of Education is of utmost importance for future actions of improvements. This type of study must be made continuously of form to evaluate Departments´ trends as well as the College´s as a whole, besides stimulating the activities of research and formation of human resources of the Departments. In this work is quantified activity of orientation and research of the Departments of the College of Engineering of Guaratinguetá - UNESP, through national and international publications in periodic, congresses and supervisions of graduation works, masters, doctoral, post doctoral, and scientific initiation, in a period five years (2007 through 2012). For balance of points to the considered issues, a criterion based on the CAPES qualification of periodic has been assumed. On the basis of the results of this work, has been observed enormous differences and particularities between the seven analyzed Departments of Education. In a general way, some Departments presented good performance in the three criteria, whereas others obtained a good performance in only one of them. The Department of Materials and Technology was the only one in which 25% of the professors obtained maximum note for the publication in periodic, while in the Departments of Civil, Electric Engineering and Mechanics 75% of the professors did not reach sufficient punctuation in order to equal a publication in periodic with B2 extract

Avaliação das impedâncias em pontos de acupuntura

An experimental study in dogs was accomplished to evaluate impedances at the acupuncture points and the relative false points. According to the physics concepts and the Ohm’ Law, an electrical circuit was set up to determine the impedance. This circuit was introduced into three experiments in anesthetized dogs with needles at selected points. In the first two experiments, was applied an alternating tension with 200Hz frequency in the circuit and, in the last experiment, the frequency was increased to 10kHz, the tensions and electrical currents were measured between every pair of points for the all experiments. The impedances were calculated with the values obtained by experiments. The analysis of impedance values indicated that there is a coherent relation between the results and the applied frequencies in circuit, so just at high frequency condition admits the correct measurement of total impedance, therefore the last experiment gave the result which agreed with the theory, that the impedances at acupuncture points are lower than the impedances at false points

Análise histomorfométrica do reparo ósseo em tíbias de ratos castrados submetidos ao efeito do alendronato sódico

This study used histomorphometric analysis to investigate the effect of sodium alendronate, used for the treatment of osteoporosis, on the repair of surgically-induced bone defects in the tibia of castrated rats. Methods: The castrated animals were given subcutaneous injections of sodium alendronate (0.7mg/Kg) diluted in saline once a week; the control animals were given the same dose of saline. At 16, 30 and 44 days after the first injection of sodium alendronate, the animals were sacrificed and the right tibias were removed and processed for histomorphometric analysis. The volumetric bone mineral density was estimated by a reticular grid (25 points) attached to a light microscope. The number of points on the bone tissue was counted in the histological sections, totaling 100 points/animal. Results: The results revealed that sodium alendronate stimulated bone formation in castrated rats in all occasions, mainly at 16 and 30 days. Conclusion: Sodium alendronate affects mineral homeostasis, promoting bone repair.

Congruent spatial and temporal foraging by a dominant ant (Hym., Formicidae) and its replacement in an assemblage in a large urban structure in southeastern Brazil

At fixed bail stations in a large institutional setting in Brazil, the temporal and spatial pattern of usage of the dominant species of ant was studied. The ant Crematogaster cf. magnifica, was found in 91% of sampling points. These studies were conducted using the same points as a previous study of tile then dominant ant. Monomorium pharaonis, which was found to have declined from 93% to 3% spatial point occupation. The frequency of point usage during this study was significantly different from the Poisson distribution for both species, indicating non-random use of space. Crematogaster cf. magnifica was significantly more spatially exclusive than had been documented for M. pharaonis, and the probability of points originally occupied by M. pharaonis later becoming occupied by C. cf. magnifica was in excess of 90%. Temporal bait exploitation patterns of the two species did not differ. These data demonstrate that structural ant communities can change over time without human intervention, although short- term stability is characteristic of the urban dominant ants in subtropical Brazil.

Counting singularities via fitting ideals

The stable singularities of differential map germs constitute the main source of studying the geometric and topological behavior of these maps. In particular, one interesting problem is to find formulae which allow us to count the isolated stable singularities which appear in the discriminant of a stable deformation of a finitely determined map germ. Mond and Pellikaan showed how the Fitting ideals are related to such singularities and obtain a formula to count the number of ordinary triple points in map germs from C-2 to C-3, in terms of the Fitting ideals associated with the discriminant. In this article we consider map germs from (Cn+m, 0) to (C-m, 0), and obtain results to count the number of isolated singularities by means of the dimension of some associated algebras to the Fitting ideals. First in Corollary 4.5 we provide a way to compute the total sum of these singularities. In Proposition 4.9, for m = 3 we show how to compute the number of ordinary triple points. In Corollary 4.10 and with f of co-rank one, we show a way to compute the number of points formed by the intersection between a germ of a cuspidal edge and a germ of a plane. Furthermore, we show in some examples how to calculate the number of isolated singularities using these results.

Rigidity for piecewise smooth homeomorphisms on the circle

We find conditions for two piecewise 'C POT.2+V' homeomorphisms f and g of the circle to be 'C POT.1' conjugate. Besides the restrictions on the combinatorics of the maps (we assume that the maps have bounded combinatorics), and necessary conditions on the one-side derivatives of points where f and g are not differentiable, we also assume zero mean-nonlinearity for f and g.
