Abstract: a field experiment was conducted on a clayey yellow red oxisol to evaluate the residual effect of the application of phosphorus and urban waste compost of the previous two years on the root production of carrot cv. brasília. the soil of the previous experiment design used a factorial consisting of three levels of phosphorus (0; 400 and 800 kg ha-1), applied as triple superphosphate combined with five levels of urban waste compost (0; 20; 40; 60 and 80 t.ha-1), was arranged in randomized complete blocks with three replicates. carrot plants were harvested 90 days after planting. after the harvest, a linear and quadratic effect for phosphorus and urban waste compost (p<0,01) was observed. the linear interaction p x quadratic urban compost was highly significant (p<0,01). the maximum root total production was 26.5 t.ha-1 corresponding to 18.5 t ha-1 of marketable yield, estimated by the calculated doses of 762.5 kg ha-1 of p2o5 and 53.2 t ha-1 of urban waste compost according to the function: y(prod) = 4.541143 + 4.0088 x 10-2 p2o5 + 2.50486 x 10-1 clx - 2.5619 x 10-5 (p2o5)2 - 1.9125 x 10-5 (clx * p2o5) - 2.216 x 10-3 clx2 (r2 = 0,96), where clx = urban waste compost. doses of urban waste compost applied to the soil, affected the values of ph, electric conductivity, and the available contents of cu and zn. even under the highest levels of phosphorus and urban waste compost applied in the experiment, no phytotoxic effect on carrot plants was observed, and in the edible part, none of the elements reached the maximum tolerant limit for food, as established by the brazilian legislation.

Abstract: Realizou-se em 1997, em condi es de campo um experimento em Latossolo Vermelho Escuro distrófico argiloso sob cerrado de Brasília, para avaliar o efeito residual das aplica es em anos anteriores, a lan o de doses de fósforo (superfosfato triplo), e de composto de lixo na produ o de cenoura (Daucus carota), cv. Brasília, assim como nos teores de cobre e zinco em raízes frescas. Aproveitou-se o mesmo delineamento experimental de blocos ao acaso com 3 repeti es, no mesmo campo experimental dos experimentos anteriores distribuídos num esquema fatorial 3 x 5 incluindo-se 3 níveis de fósforo (0; 400 e 800 kg ha-1 de P2O5) e 5 níveis de composto de lixo (0; 20; 40; 60 e 80 t ha-1). A colheita foi realizada aos 90 dias após o plantio. A análise estatística dos dados de produ o total de raízes revelou efeito residual da aduba o dos últimos dois anos em linear e quadrático altamente significativo (p<0,01) para fósforo e composto de lixo. A intera o linear de P x quadrática composto de lixo foi altamente significativa (p<0,01). A produ o total máxima de 26,5 t ha-1, correspondendo a 18,5 t ha-1 de raízes comercializáveis, foi assegurada pelas doses calculadas de 762,5 kg ha-1 de P2O5 e 53,2 t ha-1 de composto de lixo de acordo com a fun o Y(PROD) = 4,541143 + 4,0088 x 10-2 P2O5 + 2,50486 x 10-1 CLx - 2,5619 x 10-5 (P2O5)2 - 1,9125 x 10-5 (CLx * P2O5) - 2,216 x 10-3 CLx2 (R2 = 0,96), onde CLx = composto de lixo. A aplica o ao solo das doses de composto de lixo alteraram o pH, a condutividade elétrica e os teores de Cu e Zn. Mesmo nas doses mais elevadas de fósforo e de composto de lixo aplicadas n o foram observados efeitos fitotóxicos de Cu ou de Zn. Os teores desses elementos em raízes in natura estiveram abaixo dos permitidos pela legisla o brasileira de alimentos.

Ecosistemas , 2003,
Abstract: La recuperación post-incendio de la vegetación ha sido estudiada sobre todo a nivel de parcela. A escala regional diferentes factores pueden determinar la variabilidad en la capacidad de regeneración vegetal. El empleo de la teledetección permite efectuar un seguimiento de la regeneración a gran escala. En este trabajo se muestra como la recurrencia de incendios a lo largo del periodo de estudio (1975-1998) provocó una disminución significativa de la resiliencia de los bosques y matorrales mediterráneos de Catalu a. En las zonas quemadas una vez se encontró mayor resiliencia en las formaciones dominadas por especies rebrotadoras.
Understanding Eastern Europe
Ricardo D. Ferrer
Kasarinlan : Philippine Journal of Third World Studies , 1990,
Abstract: The problems confronted by Eastern European countries are hypothesized to be problems of social construction and not of socialism itself. Moreover, they are mistakes or weaknesses of an incorrect theory of socialist construction. This is based on their premature self-evaluation as socialist countries. None of these socialist countries have reached the utopian socialist state but they were broadly applying the laws appropriate to that state and it is this contradiction which has brought about the crisis in Eastern Europe. Thus, it is this study’s aim to demonstrate the feasibility of a proposed research framework on understanding the developments in Eastern Europe consisting of five steps in testing the above-mentioned hypothesis in principle. The socialist vision includes the abolition of inequality where, under this condition, equality becomes a reality. The problem with this vision is that it is utopian, even Marxists recoil from giving an explicit elaboration of the ultimate socialist vision. However, without abandoning the vision of a future society, socialism is made operational by a series of feasible structures of society. To avoid falling into this paradox, the process of construction must be consistent with the laws of social change. Only if each of the successive stages in the construction of post-capitalist society maximizes freedom, democracy and equality will the process of construction move progressively towards socialism. Until such time, Eastern Europe will tread the capitalist path.

Abstract: La desnutrición proteico-energética en América Latina aun cobra un número importante de vidas; subsisten problemas de déficit de micronutrientes y baja talla, en especial entre los más pobres. Las enfermedades crónicas relacionadas con la dieta y el sedentarismo son la principal causa de muerte en la región. En el futuro la tarea será no sólo evitar la muerte y la enfermedad, sino también a adir a os de vida saludable. Se examinan las metas del desarrollo para el milenio, consensuadas a nivel mundial por la ONU y la relevancia para los países de la región, analizando los desafíos que estas plantean. Se analizan los factores que dificultan el cumplimiento de las metas y los posibles caminos para avanzar en lograrlas. Se plantean las responsabilidades y posibles roles de los profesionales de la nutrición en alcanzar estas metas como: promover el liderazgo técnico, ético y social; definir maneras para asegurar la alimentación saludable (calidad y cantidad) como un derecho humano básico; promover acciones locales para cumplir con las metas internacionales definidas por la ONU, aconsejar estilos de vida saludables y un patrón de consumo de alimentos sustentable; proponer objetivos comunes para la acción y evaluar el impacto de las políticas y programas In Latin America protein-energy malnutrition still is an important cause of death and micronutrient deficiencies and stunting remain prevalent amongst the low socio economic groups. However, nutrition and physical activity- related chronic diseases are the main cause of death in the region. Facing the future we need to go beyond preventing death and disease; we need to add healthy life years. The UN Millennium Development Goals are analyzed in light of the challenges faced by countries in the region; barriers to the achievement of these goals are examined as well as possible ways of facilitating their achievement. Responsibilities and possible roles of nutrition professionals in achieving these goals are proposed: promoting technical, moral and social leadership; defining ways to achieve the right to adequate food (quantity and quality) as a basic human right, promote local actions to meet international goals defined by the UN, advice on healthy life styles and a sustainable food consumption pattern, all of which are common objectives for action and evaluation of the impact of policies and programs

Abstract: Un requisito previo para la planificación de una finca es disponer de información acerca de las características del productor, o productora, y su familia, así como de los recursos naturales disponibles y el sistema de producción que tiene, ya que, para proponer cambios en el uso y manejo de los recursos naturales, hay que conocer, analizar e interpretar lo que se dispone en la unidad productiva. Es por esto que se planteó caracterizar cinco fincas ubicadas en el territorio indígena Bribri en la comunidad de Shuabb, distrito Telire, cantón de Talamanca, Limón, Costa Rica, para la producción de cacao orgánico (Theobroma cacao) bajo un sistema tradicional agroforestal. El enfoque de producción orgánica con un manejo sostenible de los recursos naturales coincide con la norma tradicional y espiritual de los indígenas. Se estableció una tipología basada en aspectos biofísicos para las cinco fincas seleccionadas y una caracterización socioeconómica de las familias beneficiarias;conbaseenlosresultadosobtenidos, se propuso un dise o de producción y un manejo agronómico orgánico para el establecimiento de los sistemas agroecológicos. A prerequisite for planning a farm is to have available information about the characteristics of the producer and her or his family, about the available natural resources and about the existing production system. For proposing changes in the use and management natural resources, is necessary to know, to analyze and interpret what is available in the production unit. This is why it is plated characterize five farms located in an indigenous community named Shuabb, in Telire district, Talamanca, Limón, Costa Rica. For the organic cocoa (Theobroma cacao) production, under a traditional agroforestry system. The organic approach under a sustainable management of natural resources, coincides with the traditional and spiritual standard of the indigenous. A typology was established based on biophysical aspects for the five selected farms and a socioeconomic characterization of the beneficiary families; based on the results it was proposed a production design and an agronomic management, for establishing the agroecological systems.
