Abstract: The use of high doses of mineral fertilizers recommended for growing vegetables, besides burdening the production process, triggers the environmental imbalance. Thus, the demand for information which enables the use of different waste materials as organic fertilizers has been increasing. Therefore, the objective was to evaluate the effect of rates of residual waste of effluent treatment on morphophysiological income of Eruca sativa L. in central southern region of the state of Tocantins. The experiment was performed with the culture of the rocket, underwent five treatments that consisted of five doses of the residue (0, 20, 40, 60, and 80 Mg ha-1) and three replications. The characteristics evaluated were: total dry matter (g), leaf number, leaf area (cm2) and net assimilation rate. For every characteristic, samples were collected for analysis at 10, 15, 20, 25, 30 and 35 days after sowing. For all traits there was positive effect of the residual dose, responding to higher doses (60 and 80 Mg ha-1). The use of refrigerated beef residue as an alternative fertilizer promoted the development of the rocket with an increase in production until the dose of 80 Mg ha-1. El uso de altas dosis de fertilizantes minerales que se recomienda para cultivos de hortalizas, además de sobrecargar el proceso de producción, provoca el desequilibrio ambiental. Por lo tanto, la demanda de informaciones que puedan permitir el uso de residuos orgánicos como fertilizante diferentes es creciente. Así, el objetivo fue evaluar el efecto de diferentes niveles de residuos de lagunas de tratamiento de residuos en los ingresos morfo fisiológicos de Eruca sativa L. en centro-sur del estado de Tocantins. El experimento se estableció con la cultura de la rúcula, sometida a cinco tratamientos que corresponden a cinco dosis del residuo (0, 20, 40, 60 y 80 Mg ha-1) con tres repeticiones. Estas características fueron: masa seca total (g), número de hojas, área foliar (cm2) y la tasa de asimilación neta. Para cada característica se recogieron muestras para su análisis en los días 10, 15, 20, 25, 30 y 35 después de la siembra. Para todas las características evaluadas, hubo un efecto positivo de la dosis de los residuos, manteniendo respuesta incluso en las dosis más altas (60 y 80 Mg ha-1). El uso de los residuos de matadero bovino como fertilizante alternativo he promovido el desarrollo de rúcula con un aumento en la producción hasta la dosis de 80 Mg ha-1. O uso de elevadas doses de fertilizantes minerais recomendadas para o cultivo de olerícolas, além de onerar o processo produtivo, desencade

Abstract: La definición y la recomendación de las especies para las diferentes etapas de sucesión en las zonas en proceso de recuperación dependen de su comportamiento en ambientes bajo diferentes intensidades de luz. Por lo tanto, el presente trabajo tuvo como objetivo definir la etapa de sucesión en que las plantas de Aspidosperma polyneuron Müll Arg deben ser indicado para su uso en los proyectos que se ocupan de la recuperación de áreas degradadas en función de la intensidad de la luz. El experimento se llevó a cabo en un dise o de bloques al azar con 15 repeticiones. Los tratamientos consistieron en tres niveles de brillo (T1: Pleno sol, T2: 50% de retención de la luz y T3: sombra natural). La recolección de datos se realizó a intervalos de 21 días, hasta 145 días después de la emergencia (DDE). las plantas de Aspidosperma polyneuron Müll presentado a diferentes niveles de intensidad de la luz mostró una función lineal del tiempo de la siembra. Cuando se cultivan en la luz del sol el 50% tuvo una tasa de crecimiento en altura y diámetro mayor que las plantas bajo luz solar plena. El mayor peso de la masa seca del tallo y de la raíz y también total se observaron en los entornos del 50% de luz. Todas las características evaluadas mostraron incrementos en la masa por el aumento de la intensidad de la luz. A defini o e a recomenda o das espécies para os diferentes estágios sucessionais em áreas sob processo de recupera o s o dependentes do seu comportamento em ambientes sob diferentes intensidades de luz. Assim, com o presente trabalho objetivou-se definir o estágio sucessional em que as plantas de Aspidosperma polyneuron Müll Arg devem ser indicadas para o uso em projetos que visam de recupera o de áreas degradadas em fun o da intensidade de luz. O experimento foi desenvolvido em delineamento de blocos casualizados com 15 repeti es. Os tratamentos foram constituídos por três níveis de luminosidade (T1: Pleno sol; T2: 50% de reten o de luz e T3: Sombra Natural). A coleta dos dados foi realizada em intervalo de 21 dias, até os 145 dias após a emergência (DAE). As plantas de Aspidosperma polyneuron Müll submetidas aos diferentes níveis de luminosidades apresentaram comportamento linear em fun o do tempo após o plantio. Quando cultivadas em ambiente com 50% de luminosidade apresentaram taxa de crescimento em altura e diametro superior às plantas submetidas a pleno sol. Os maiores pesos de massa seca caule, raiz e total também foram observados em ambientes de 50% de luminosidade. Todas as características avaliadas apresentaram incrementos de massa pelo aument

Abstract: El aumento de la industrialización y la agricultura en Brasil ha promovido la generación de residuos en cantidades significativas a la ocurrencia de impacto ambiental. Sin embargo, cuando se gestionen estos mismos residuos según una base científica, estos pueden ser utilizados como materia prima en la producción de alimentos. Este estudio tuvo como objetivo evaluar el efecto de la aplicación foliar de la orina de vaca en el desarrollo inicial de las plantas de Tabebuia impetiginosa. El experimento se llevó a cabo en el dise o completamente al azar con siete tratamientos. Cinco tratamientos se establecieron mediante la dilución de la orina de vaca productora de leche en agua para obtener concentraciones de 1, 2, 3, 4 y 5% (v / v), y los adicionales sin aplicación de la orina y fertilización foliar con 0,3% de nitrógeno, con cuatro repeticiones. En la dosis de 0% (agua pura) se aplicó sólo agua. Las diluciones se prepararon mediante la dilución de la orina en agua limpia antes de la aplicación a las plantas. La orina almacenada se aplicó en el tratamiento de la fase inicial hasta 75 días después de su recolección. La fertilización foliar con concentraciones de orina y urea fueran realizadas al mismo tiempo que se realizaron las mediciones de altura y diámetro. El uso de la orina de vaca en concentraciones superiores al 3% proporciona un aumento en el desarrollo, crecimiento, producción de materia seca de la parte aérea de lo dosel vegetativo, radicial y la masa seca total de las plantas de Tabebuia impetiginosa en comparación con los fertilizantes minerales convencionales (urea 0,3% de N ). The increasing industrialization and agriculture in Brazil has promoted the generation of waste in significant amounts for the occurrence of environmental impact. However, these same residues, when managed under a scientific basis, could be used as raw material in food production. The present study aimed to evaluate the effect of foliar application of cow urine in the initial growth of Tabebuia impetiginosa. The experiment was conducted in a completely randomized design with seven treatments. Five treatments were set through the dilution of dairy cow urine in water to obtain concentrations 1, 2, 3, 4 and 5% (v/v), and additional urine and the lack of foliar fertilization with a 0,3% nitrogen, with four replications. At the dose 0% (pure water), it was administered only water. The dilutions were prepared by diluting urine into pure water moments before its application to the plants. The stored urine was applied in treatments of the initial period up to 75 days after coll

Abstract: In the last years the sorghum production in Brazil has increased so much, as consequence of the expansion of the planted area and productivity increments. However, studies of the organic manuring on the development of the culture are still incipient. In that way, it was aimed at to evaluate the effect of the applied organic manuring in the planting furrow in the development of plants of Sorghum bicolor. The experiment was droven in randomized blocks design, with six repetitions, being the hybrid of grain sorghum A9735R submitted to eight treatments: 0, 10, 20, 30, 40, 50 and 60 t ha-1 of organic fertilizer applied in the planting furrow and 500 kg ha-1 of the formulation 04-14-08 + Zn. The concentrations of organic manuring in the planting furrow provided differences among the treatments. Being observed that you plant submitted to the doses 40 to 60 t ha-1 organic manuring presented better vegetative acting for the appraised parameters. The largest answer of growth of the stem was what received 40 t ha-1 of organic manuring.

Journal of Biotechnology and Biodiversity , 2012,
Abstract: The knowledge of the behavior of forest species in areas with different intensity of light, enables the definition andrecommendation of the species in the recovery process. Thus, we aimed at verifying the influence of shading onseedling quality of Sclerolobiumpaniculatum Vogel in restoration projects of degraded areas. The experiment wasconducted as a randomized block design with 15 replications. The treatments consisted of three levels of brightness(T1: 0%, Full sun, T2: 50%, Sombrite with 50% retention of light and T3: Shadow Natural). PlantsSclelorobiumpaniculatimVog.grown in an environment with 50% sunlight had a growth rate in height (2: 0.0266)40% higher than plants in full sun (2: 0.0161), most notably from the 103-day evaluation. Under natural shadinghad the lowest rate of development along the neck of the evaluation period, representing only 5.43% (2: 0.0193)rate of development of plants under full sunlight (2: 0.3557). The increase in light intensity favors the majordevelopment of SclerolobiumpaniculatimVog. With that, may be indicated for use in projects aimed at recovery ofdegraded areas in the early successional pioneer and early secondary.

Entre o uso social e o abuso comercial: as percep??es do patrim?nio cultural subaquático no Brasil
Rambelli, Gilson;
História (S?o Paulo) , 2008, DOI: 10.1590/S0101-90742008000200004
Abstract: the aim of this paper is to present some reflections about cultural and archaeological underwater heritage, to arrive at an analysis as to what degree distortions of concepts exist in this "submersed" theme, result from a millenary history of adventures, and how they have contributed and continue to contribute to the destruction of different archaeological submersed sites. the article also aims at contributing to a wider understanding of underwater heritage, and the necessity of systematic, underwater, archaeological research. it draws attention especially to the brazilian problem, because brazil still permits the commercial exploitation, and consequently, the destruction of this cultural heritage. this has been made possible through inadequate legislation inspired on the millenary fantasies of underwater treasure and fortune.
A tese que é uma hipótese
Schwartz, Gilson;
Lua Nova: Revista de Cultura e Política , 1994, DOI: 10.1590/S0102-64451994000100006
Abstract: comenting on van parij's paper on "basic income capitalism" the author argues that the proposal for a guaranteed basic income in a capitalist economy faces the same dificulties of other proposals for the realization of non-economic values and preferences that are unwilling to give up the logic of the market, like investment planning or the taxation on pollution promoters. to supose that the distribution implied in warranting a basic income for everyone would not violate the economic market mechanism means to pressupose precisely the point to be demonstrated.
