The objective of the present study was to determine the transport rate of a fungus population associated with Jatropha curcas seeds and the pathogenicity of these microrganisms to seedlings and fruit and also the fruit-seed and seed-seedling transmissibility. The transport rate of seeds produced in Minas Gerais, São Paulo, Bahia and Tocantins states was evaluated using the blotter test. The seeds were submitted to the following treatments: without disinfestation, with tegument (SDCT), without disinfestation, without tegument (SDST), with disinfestation, with tegument (CDCT) and with disinfestations, without tegument (CDST). The incidence (%) of the fungi was assessed using a binocular stereomicroscope. Suspensions of 106 spores and PDA discs with mycelium were inoculated for the pathogenicity tests on seedlings and fruits, respectively. For the phytopathogenic fungi, the fruit-seed and seed-seedling transmissibility were evaluated. The SDCT treatment allowed the detection of a greater number of fungi. The identified fungi were Colletotrichum gloeosporioides, C. capsici, Curvularia sp., Verticillium sp., Fusarium sp., Penicillium sp., Aspergillus sp., A. Niger, Rhizopus sp. Only the Colletotrichum species is pathogenic to seedlings and fruit. For both species there is fruit-seed transmissibility but no seed-seedling transmission.

The synthesis of bioactive compounds with antimicrobial activity, excreted by marine cyanobacteria, strongly depends on their growth conditions. Due to the wide variety of biomolecules which could show properties as growth inhibitors and their low concentrations within the culture medium, the activity of their crude extracts also seems to be related to the extraction method used. Using the marine filamentous cyanobacterium Geitlerinema strain Flo1, we demonstrate a systematic approach for identifying optimal culture conditions to obtain culture media extracts with antimicrobial activity. The changes in the culture conditions, such as the addition of NaBr to the medium, cell immobilisation in vegetable sponge pieces, or temperature, effected the production of these bioactive compounds. The crude extract, containing middle polar molecules, obtained by extraction with Amberlite XAD-1180 had a higher antifouling activity upon a number of bacteria and fungi than the extract obtained by extraction with Amberlite XAD-16. The lowest inhibitory concentration obtained upon Rhodosporidium sphaerocarpum was still ten times higher than that of bis(tributyltin)oxide, but compared to zinc pyrithione, it was two times more active. © 2010 Springer Science+Business Media B.V.

The objective was to evaluate four levels of inclusion of babassu mesocarp meal (Orbygnya spp.) in the concentrate on cattle feedlot performance. Twenty four animals (12 steers and 12 bulls) were used with age and body weight of 33 months and 332.1±24kg, respectively. Diets were isonitrogenous, composed of 44% of Mombasa grass silage and 56% of concentrate in dry matter. Corn grain of the concentrate fraction was replaced by babassu mesocarp meal at 0, 20, 40 and 60% in dry matter. The experimental design was randomized complete block, with factorial arrangement of treatments 4x2 (four levels of babassu mesocarp meal inclusion and two sexual conditions). Dry matter intake in kg day 1 and percentage of body weight was not altered by the inclusion level of bran babassu mesocarp, with average values of 9.37kg day -1 and 2.54% respectively. Inclusion levels of babassu mesocarp meal did not affect daily weight gain and feed conversion the animals, with average values of 1.157kg day -1 and 8.39kg of dry matter kg -1 weight gain. Bulls had higher daily weight gain (1.259kg day -1) than steers (1.066kg day -1), reflecting a better feed conversion (7.702 and 9.094kg dry matter kg -1 weight gain, respectively). Babassu mesocarp meal, such as alternative energy source, can be fed to feedlot to the 60% level of inclusion in the concentrate, replacing corn grain.

This study aimed to evaluate the effect of applying different pre-emergent herbicides, alone and in combination, on sunflower crop in wetland soil. The sunflower variety Embrapa V122 and the triple hybrid Agrobel 972 were evaluated individually using a randomized block design with four replications. Two experiments were conducted, with the following treatments being used in both: Oxadiazon (250 g ha-1), oxyfluorfen (240 g ha-1), S-metolachlor (1.440 g ha-1), flumetsulam (120 g ha-1), pendimethalin (1.000 g ha-1), oxyfluorfen+S-metolachlor (192+960 g ha-1), flumetsulam+S metolachlor (72+960 g ha-1), pendimethalin+S-metolachlor (1.000+1.440 g ha-1), pendimethalin+flumetsulam (1.000+72 g ha-1), and two controls, with and without weeding. Plant height, stem diameter, chapter and grain yield diameter were submitted to statistical multivariate tests of cluster analysis and Principal Components Analysis. The results were similar in both cultivars evaluated, showing the formation of three main groups. with the first and second groups consisting of the controls with and without weeding, respectively. The third group was composed of the herbicides applied alone and in combination. The effects caused by the herbicides applied alone and in combination on the variables analyzed were found to be less harmful than the effects of weed interference. These results show the potential for selectivity of the herbicides applied alone and in combination on the sunflower variety Embrapa V122 and on the triple hybrid Agrobel 972, under the evaluated conditions.

This research's objective was to study the efficiency in the usage of nitrogen in rice cultivars on high land in the south of Tocantins State. The experiments involved sex commercial cultivars of rice (BRS-Bonança BRSCaiapó, BRS-Sertaneja, BRSMG-Curinga, BRSMG-Conai and BRS-Primavera), which were farmed in two distinct environments. In order to stimulate areas with high and low nitrogen levels, there were used doses of 20 and 120 kg ha-1 of P2O5 respectively. The experiments were carried out in a completely randomized blocks design, with four replicates. Throughout production the grain's productivity was classified as efficient cultivars in respect to the application and response of nitrogen. Did not identify efficient cultivars in response to the usage of nitrogen. The cultivars BRS-Bonança, BRS-Caiapó and BRS-Primavera demonstrated efficiencies in the use of nitrogen and no responsive to its application.

This study was conducted in order to evaluate the influence of different levels of metabolizable energy and crude protein in diets formulated according to the ideal protein concept with phytase supplementation on performance and nutrient excretion of broilers from 22 to 42 days age. It was used 1,500 Coob lineage broilers at 22 days of age and with initial weight of 833 ± 7g, distributed in completely randomized design in a 3 × 3 + 1 factorial scheme composed of three levels of correct apparent metabolizable energy (2,950; 3,100 and 3,250 kcal/kg), three levels of crude protein (14, 16 and 18%) and a control treatment, totaling ten treatments with six repetitions of 25 birds each. All diets, with the exception of the control, were supplemented with phytase. For determination of excretion of pollutants, it was used 180 broilers from the same lineage at 35 days of age, placed in metabolic cages, with ten treatments each one with six repetitions and three birds per experimental unit. The protein and energy levels in diets containing phytase influenced feed intake, weight gain, feed conversion and excretion of nitrogen, phosphorus, calcium, potassium, copper and zinc by the birds. The corrected apparent metabolizable energy level in the diets for broilers in the studied period must be increased up to 3,250 kcal/kg of metabolizable energy and the levels of crude protein, calcium and phosphorus must be reduced down to 18, 0.70 and 0.31%, respectively, provided that supplemented with amino acids and phytase to improve the performance and to reduce excretion of pollutants by birds. © 2011 Sociedade Brasileira de Zootecnia.

This study aims to verify that the equation proposed by Dexter et al. (2007) for calculating the soil resistance to penetration, based on the reciprocal of the S index and on effective stress is applicable to 'Cerrado' soils. Correlation was established between the calculated values and soil attributes and it was compared with critical values in the literature and field data. The study was conducted with 2242 soil samples of 'Cerrado' soils, which contained information on textural classification, bulk density and soil water retention. It was found that value of soil penetration resistance equal to or greater than 1900 kPa, determined at soil water content equivalent to field capacity, can be considered indicator of compacted soils and that the equation proposed by Dexter et al. (2007) to estimate the soil resistance to penetration is adequate for 'Cerrado' soils. However, it should be further tested to determine its predictive power.

Niobium electropolishing for SRF cavities are generally considered to be the best technology today. However, hydrofluoric and sulfuric acid mixture usually used in the EP process is harmful and requires us carefully controlled handling of it and the many additional facilities. In this article, we propose a new application of electrochemical buffing (ECB) to niobium SRF cavity. In the method of ECB, a rotating disk with abrasive fine particles where electrolyte is supplied is pressed against the workpiece. The disk and the work function as a cathode and an anode, respectively and an aqueous solution of sodium nitrate is used for the electrolyte. This technology brings us a couple of remarkable advantages like high etching rate, ultra small surface roughness, cost-effective and environment-compatible polishing.

Bacaba (Oenocarpus bacaba) is a palm species typical from Amazon region, widely used by local people for feeding. This work aimed to evaluate the effect of different conditions of temperature and substrate in the germination of seeds and to determine the seed storage behaviour of bacaba (Oenocarpus bacaba) seeds. Fruits were collected at Caseara, Tocantins, Brazil. The germination was carried out at different temperatures and substrates after cleaning. Seed viability was also determined after drying at different water content in order to determine the seed storage behavior. The best substrate for germination of bacaba seeds was in sand. It was not verified effect of temperature on the germination of the seeds, except when seeds were incubated at 35 °C, which germination was not observed. Although there is no effect on the most of the temperature tested on the final percentage of germination, seeds incubated at 30 °C and 25-35 °C showed higher speed of germination. Seeds of bacaba cannot be dried below 0,36 g H2O g-1 dry weight, and so they are classified as recalcitrant.
