There were significant general and specific combining ability amongst cultivars and reciprocal effects. The cultivar IAC Campinas A reduced the initial fruit set at all crossing in which was used as female progenitor. The best results for initial fruit set were showed by crossings between following cultivars: IAC 4-20 × IAC Campinas A, IAC 4-12 B × IAC 2-23 A, IAC 4-20 x× IAC 4-12 B, IAC 5-10 × IAC 2-23 A, IAC 5-10 × IAC 4-20, IAC 4-20 × IAC 2-23 A e IAC 5-10 × IAC 4-12 B.

Parâmetros geotécnicos e previsão da capacidade de carga de estacas apiloadas em solo tropical arenoso obtidos com o Pressiômetro Ménard

This paper presents and discusses Ménard Pressuremeter test results used to predict bearing capacity of pounded piles installed in a tropical sandy soil. Fifteen pre-bored pressuremeter tests were carried out at the Experimental Research Site from Unesp - Bauru up to 15 m depth, one test per meter. Several laboratory and in situ tests were carried out in this research site as well as load tests on plates and on piles. Pressuremeter test results were firstly analyzed to determine geotechnical soil parameters based on empirical methods, emphasizing the estimative of the earth pressure coefficient at rest (K0). After that, bearing capacity prediction of pounded piles with 4 m, 7 m and 10 m were made and compared with test results from instrumented load tests. Pressuremeter test results allowed a very good estimative of bearing capacity for the pile with 4 m length and underestimated in 25,7% and 20,0% the bearing capacity for the pile with 7 and 10 m length, respectively. The back analysis of the test results suggests that the appropriate value for the bearing capacity factor for the tested soil-pile system on this soil is equal to 2.

Cor, capacidade de retenção de água e maciez da carne de cordeiro maturada e injetada com cloreto de cálcio

Biceps femoris, Longissimus and Triceps brachii muscles from Morada Nova lambs were submitted to ageing and calcium chloride injection. Colour, water holding capacity and tenderness were studied. Lambs were slaughtered weighting 25kg.. The muscles presented differences in colour (lightness-L*, redness-a* and yellowness- b*) 24 hours after rigor mortis instalation. Ageing intensified redness of the meats. Calcium chloride did not modify the colour of Longissimus and Triceps brachii, however, Biceps femoris became more redness after receiving calcium chloride. In relation to water holding capacity, ageing affected meats from Triceps brachii. However, it did not affect Biceps femoris and Longissimus. The calcium chloride didn't modify the water holding capacity of the muscles. Ageing influenced tenderness of Biceps femoris and Longissimus.

Geoprocessamento aplicado na distribuição espacial da capacidade de uso de uma microbacia

The present study aimed to show the spatial distribution of the Rochas watershed (Avaré-SP, Brazil) soil use capacity using the Idrisi geographical information system in order to contribute to a better territorial organization and the planning of the appropriate soil occupation. The obtained results using this methodology showed that most of the Rocha watershed areas are from the following groups: dystrophic yellow-red latosol (36.64%), eutroferric and distroferric red latosol (30.30%) with sandy texture. There was a predominance of areas with slope classes of 0-12%, plain to wavy relief (61.37% of the watershed area) showing that these areas are appropriate for annual culture plantations with wide use of machinery. Most of these areas were classified as class IV (73.79%) as to use capacity. In the studied area the following subclasses of land use capacity were found: IIe, s; IIIe; IVe; IVs; IVe,s; VIe and VIIe. Capacity subclasses IVe; IVe,s; IVs and Vie were the most significant because they are areas that can be used for agriculture but subject to severe soil impoverishment if there are no special care mainly for annual cultures. The Idrisi geographical information system was efficient to determine soil use capacity of the Rocha's watershed showing that the use of geoprocessing tools makes data analysis easier and faster, allowing digital data storage for future analysis uses mainly for territorial planning and environmental studies.

Capacidade de carga real (ccr) da caverna de santana, parque estadual turístico do alto ribeira (Petar) - sp, e indicações para o seu manejo turístico

The tourist use of Santana cave provides a row of environmental damages, compromising partially the pristine conditions. Among the measures adopted to avoid this situation, this issue presents a contribution for the physical limits to tourist visitation and the indications for speleotouristic management. It was used the Cifuentes Carrying Capacity method and some basic principles of Visitors Impact Management Framework - VIM. The results show a Real Carrying Capacity (CCR) about 120 visits daily on the cave. The discussions raise a few hypotheses about the alteration in the method used and the temporal frequency between visitors groups, suggesting a provisional CCR of 117 and 135 visitors daily, respectively, during the week and in the weekends and holidays. The conclusions appoint the necessity of a conceptual revision in the Carrying Capacity methods, mainly about its adaptation for tourist management in caves. In the case studied, it is suggested the immediate beginning of environmental monitoring of the cave, to verify the plausibility from proposed visitation limits and the possible contributions for to mitigate the environmental impacts from speleotourism.

Resposta imune e capacidade de neutralização de anticorpos produzidos em ovinos jovens imunizados com veneno de Crotalus durissus terrificus nativo e irradiado com Cobalto 60

The ELISA technique was used to evaluate and compare young ovine humoral immune response during crotalic antiserum production. Animals were clinically evaluated throughout this process, and the neutralizing capacity of antisera raised against natural (NV) and Cobalt-60 irradiated (IrV) venoms of Crotalus durissus terrificus (C.d.t.) was verified by means of in vitro challenges. Three groups of six animals each were used: G1 received NV; G2 was inoculated with IrV; and G3 was used as control. Animals received six immunizations during 84 days at 14-day intervals. ELISA of antibody profile showed significant difference (p<5%) between experimental groups (G1detoxify Crotalus durissus terrificus venom like alternative to antiserum production. The neutralizing capacity of antiserum raised against IrV was fivefold higher than that of antiserum raised against NV. Results showed a new possibility of using ovines to produce commercial crotalic antiserum, which may be employed in the treatment of human and animal envenomation. Production cost might be reduced by the subsequent utilization of hyperimmunized ovines as food.

Sistema de informações geográficas aplicado à espacialização da capacidade de uso da terra

This research aimed to study land use capability classes in Pratânia, São Paulo State, Brazil, by using the Geographic Information System (GIS), in order to find out the appropriate planning system for soil use. The watershed covers an area of 21,773.61 ha and is located among the coordinates 22°44'48S and 22°52'17S and 48°38'21W and 48°48'07W. The land use capability map was made from the slope and soil maps, based on the features of each kind of soil and the land use capability table for class assessment. It was possible to conclude that IIIs was the most significant subclass. Slope classes from 0% to 20% were present in more than 97% of Pratânia, being the plane areas the most representative ones (55%). GIS showed to be an excellent tool for determining land use capability, because the geoprocessing use facilitates and activates the digital data crossing, allowing its storage for future environmental planning.

The objective of this study was to analyze effects in different depth in soil water infiltration and to verify the Horton and Kostiakov-Lewis models adequacy in infiltration rate estimate. The treatments were five doses of vinasse (0, 200, 250, 300 and 350 m3?ha1?. The vinasse application reduced the soil erosion risk increasing the possibility of runoff. The Horton model had the best adjustment on the observed data, and the Kostiakov-Lewis model overestimated the infiltration rate values.

Dependência estrutural da capacidade de rotação plástic em vigas de concreto armado

Summary In this work the structural dependence of plastic rotation capacity in RC beams is evaluated using the Finite Element Method. The objective is to achieve a better understanding of the non-linear behavior of reinforced concrete members and perform extensive parameter studies, using a rational model developed by Bigaj [1] to analyze the phenomenon of plastic rotation capacity in reinforced concrete members. It is assumed that only bending failure is relevant due to sufficient member resistance against shear and torsion. The paper begins with the physical and theoretical background of the phenomenon of plastic hinge development in RC structures. Special emphasis is laid on the issue of structural dependence of deformation capacity of plastic hinges in RC members. Member size dependence and influence of properties of construction materials were emphasized as well. The essential components of the Bigajs model for calculating the plastic rotation capacity are discussed. The behaviour of the plastic hinge is analysed taking into account the strain localisation in the damage zones of the hinge region. The Fictitious Crack Model (FCM) and the Compressive Damage Zone Model (CDZ) are adopted in a Fracture Mechanics approach to model the behaviour of concrete in tension and compression, respectively. The approach is implemented in FEMOOP, a FEM in-house solver under development, and applied to evaluate ductility in 2D beams. The models were generated with GiD, a pre-processor and post-processor developed by CIMNE, and analyzed with the capabilities implemented in FEMOOP. © Universitat Politècnica de Catalunya, Barcelona, España 2010.

Capacidade predatória de chrysoperla externa sobre bemisia tabaci biótipo b expostas ao fungo metarhizium anisopliae

The objective of this study was to determine the influence of Metarhizium anisopliae on the predatory capacity and functional response of Chrysoperla externa fed Bemisia tabaci B biotype rearing cotton. The stock rearings of B. tabaci B biotype and C. externa were maintained in cages according to preexisting methodologies. Upon hatching, predator larvae were fed on eggs of Ephestia küehniella until their 3rd instar and then fed on whitefly nymphs in density exceeding their intake capacity (150 nymphs/individual). The nymphs were offered on cotton leaf disks (5 cm diameter), 24 hours after the treatments application following: T1: Control (water); T2: M. anisopliae at the concentration of 105 conidia cm-3; T3: 10 8 conidia cm-3 origined from Metharril® formulation of the 109 viable conidia cm-3 M. anisopliae active principle. The predatory capacity was obtained by the difference between the numbers of nymphs supplied and nymphs left. Five different nymphal densities (130, 160, 190, 220, and 250) were selected for the functional response study. The number of nymphs preyed was recorded after 24, 48, 72, and 96 hours. The M. anisopliae entomopathogenic fungi did not influence predatory capacity of C. externa which ranged from 70.6 individuals at the highest concentration to 87.1 in the control. Conclued that the C. externa predatory capacity was not affected by fungi M. anisopliae concentrations. The predator showed a type-II functional response after 24 hours, and a type-I response after 48, 72s, and 96 hours independent from fungi concentrations.

Influência da posição e tempo de irradiação sobre a capacidade de desinfecção em forno de micro-ondas

Objective: To evaluate the variations of temperature in 2 models of domestic micro-wave ovens, single emission (F 1) and dual emission of waves (F 2), to investigate areas of higher and lower intensity of the electromagnetic field. Materials and methods: A beaker containing water (60mL, 26°C) was irradiated into each of 5 positions (front - P 1; right - P 2; posterior - P 3; left - P 4; central - P 5) within each oven (900W/ 2min). To evaluate the effectiveness of disinfection in F 2, Bacillus subtilis suspension was irradiated in each of the 5 positions for 2, 4 and 6minutes. Data were analyzed by Kruskal-Wallis and nonparametric multiple comparisons at 5% significance level. Results: 84.80°C (F 1) and 92.01°C (F 2) were mean levels of temperature. For F 1, the positions P 1, P 2, P 3 and P 5 showed similar values among them and upper than P 4, while for F 2, the positions P 1, P 2 and P 4 were similar among them and upper than P 3 and P 5. Kruskal-Wallis test found significant differences between positions and models of ovens (p<0.05). It was observed that P 2 promoted bacterial death from 4min of irradiation, while the other positions promoted disinfection at 6min of irradiation. Conclusion: The protocols of position and time specified for the various procedures in microwave ovens can be different according to the characteristics of each device due to the electromagnetic field heterogeneity. © 2011 Sociedade Portuguesa de Estomatologia e Medicina Dentária.

Avaliação da capacidade de uso da terra da bacia do córrego do cavalheiro - Analândia, SP

Environmental factors are important in agriculture and need to be considered for getting good degree of development and reasonable efficiency, by reducing their operating costs. To this end, land use shall be appropriated to the conditions offered by the physical elements of the landscape. By facing such questions, this paper aims is to present of mapping the ability of land use of the hydrographic basins Cavalheiro Stream basin (in the city of Analândia - São Paulo State - Brazil) which presents serious erosion problems. Besides it aims to assess if the current land use in this area is consistent with the identified land use ability. For this we have made a cartographic document that spatializes the various classes of usability and its main restrictions. The correlative analysis between that document and land use data showed that Cavalheiro Stream's current use is predominantly inappropriate with the usability of land, which was identified from the physical attributes of the studied area, except for a few sites that are used for forestry and pasture placed in Western, Eastern and Central-South.
