Abstract: In the humid tropics, the largest obstacle to the implementation of sustainable farming systems is the reduced efficiency of nutrient use by crops. This study assesses the effectiveness of five selected rhizobia strains in symbiosis with cowpea (Vigna unguiculata (L.) Walp.), with the objective of replacing N fertilization in the predominant agricultural system used by smallholder farmers. The study was carried out in three adjacent areas with distinct agricultural uses: conventional tillage, itinerant agriculture, and a no-till system. The experimental design was in randomized complete blocks with four replicates and seven treatments: five rhizobia strains (BR3262, BR3267, BR3299, INPA3-11B, and UFLA 3-84) and two controls without inoculation (one without mineral N and another fertilized with 74 kg N ha-1). We measured the dry mass of 100 grains, nodules and shoots, as well as cowpea yields and calculated relative and absolute efficiency indices for dry biomass production of cowpea shoots. Agricultural uses affected the number and dry mass of the nodules and, consequently, the mass of the dry plant matter and bean yield. In terms of yield, there was a major difference between the conventional and the itinerant systems. Yield was around four times as high in the itinerant system (1009.9 kg ha-1 compared to 243.7 kg ha-1). Under conditions of cohesion-prone soils, the system of conventional tillage reduces the possibility of cultivation of a second harvest in the year even with inoculation or N fertilization. En los trópicos húmedos, el mayor obstáculo para la aplicación de sistemas de agricultura sostenible es la reducción de la eficiencia del uso de nutrientes por los cultivos. Este estudio evalúa la eficacia de cinco cepas de rizobios seleccionados en simbiosis con frijol (Vigna unguiculata (L.) Walp.), con el objetivo de sustituir la fertilización nitrogenada en el sistema de uso de suelo predominante utilizado por los peque os agricultores. El estudio se llevó a cabo en tres zonas adyacentes de distintos usos agrícolas: labranza convencional, agricultura itinerante, y un sistema de no laboreo. El dise o experimental fue en bloques al azar con cuatro repeticiones y siete tratamientos: cinco cepas de rizobios (BR3262, BR3267, BR3299, INPA3-11B y UFLA 3-84) y dos controles sin inocular (uno sin N mineral y otro fertilizado con 74 kg de N ha-1). Se midió el peso en seco de 100 granos, de los nódulos y de los brotes, así como los rendimientos de frijol y se calcularon los índices de eficiencia relativa y absoluta para la producción de biomasa seca de los

REDES DE SOCIABILIDADE E DESENVOLVIMENTO URBANO: A TECEDURA DA COMUNICA O
Maria Cristina Dadalto
Revista Perspectivas de la Comunicación , 2009,
Abstract: Desde el punto de vista teórico y metodológico de Henry Lefebvre, se examina la relación entre ciudad, comunicación y sociedad, teniendo como referencia la ciudad de Colatina, ubicada en el norte de Espírito Santo, cuyo desarrollo socioeconómico se siente alentado por la continua formación de redes productivas socio empresariales. En la construcción de los vínculos, los nudos y los principios generadores de las redes se entremezclan produciendo una dinámica, a nivel diacrónico y sincrónico, en la que los nuevos discursos ayudan a cambiar el significado de los demás. A través de una descripción e interpretación de mapas, que representan juntos los mecanismos de escala, proyección y simbologías de la red, entiende que la historia de la ciudad y sus transformaciones socioeconómicas son marcadas por huellas y marcos, que comprenden el conjunto de significados de las prácticas socioculturales que alimentan la vida cotidiana de los hombres en su realidad y para expresar a través de la comunicación, utilizando el lenguaje verbal o no verbal.

Abstract: OBJETIVO: analisar aspectos constitutivos das narrativas de histórias e relatos em crian as de 5 e 6 anos. MéTODOS: participaram deste estudo 50 crian as, de ambos os sexos, sendo 23 meninos e 27 meninas das classes de pré-alfabetiza o de quatro Escolas Particulares da Praia do Canto, bairro de classe média alta da cidade de Vitória-Espírito Santo. A amostra foi constituída da narrativa de uma história e de um relato, numa intera o informal em que foi solicitada à crian a que narrasse a história de "Chapeuzinho Vermelho", por ser uma história das mais conhecidas, e fizesse um relato de uma situa o vivida. Os critérios de análise foram baseados em Perroni (1992) e em Brand o e Spinillo (2001). RESULTADOS: a popula o apresentou conhecimento da estrutura da narrativa; domínio satisfatório da rela o temporal entre eventos narrados; utiliza o de ora es que expressam a dependência temporal com verbos de a o no pretérito (perfeito e imperfeito); utiliza o de operadores narrativos com predominancia de "aí" e "depois"; utiliza o de pontos de referência temporal e espacial com propriedade; rela es espa o-temporais bem organizadas e as causais em fase de estrutura o. Apontou, ainda, a importancia da participa o do interlocutor na constru o das narrativas. CONCLUS O: as crian as apresentaram maior facilidade na produ o da história que no relato; respondem a todo tipo de pergunta eliciadora; a maior parte precisou de media o apenas no relato; respeitam a seqüência temporal tanto na história, usando as figuras da história de maneira correta, quanto no relato e utilizam principalmente o "aí" como elemento de coes o causal e temporal.

Computer Science , 2014,
Abstract: Information is the key asset of all organizations and can exist in many forms. It can be printed or written on paper, stored electronically, transmitted by mail or by electronic means, shown in films, or spoken in conversation. In today's competitive business environment, such information is constantly under threat from many sources, which can be internal, external, accidental, or malicious. Joomla is a very popular Content Management System (CMS) used for web page maintenance. This highly versatile software has found itself in both large corporate web portals, and simple web pages such as blogs. Such popularity increases its vulnerability to potential attacks and therefore needs an appropriate security management. ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) created the series of standards aimed at providing a model for establishing, implementing, operating, monitoring, reviewing, maintaining and improving an Information Security Management System (ISMS). This paper shows how principles set in ISO/IEC 27000 series of standards can be used to improve security of Joomla based web portals.

Abstract: barley yellow dwarf virus-pav, among the virus species that cause yellow dwarf disease in winter cereals, is predominant in southern brazil. genetic resistance and tolerance to the virus and to the aphid vector are important strategies to control this virus. brs timbaúva shows low reduction of productivity, in relation to other wheat cultivars, when exposed to aphid-virus complex, and is resistant to the rhopalosiphum padi vector. this work aimed to establish if this cultivar is also resistant or tolerant to bydv-pav. the experiments were carried out comparing brs timbaúva and embrapa 16 (susceptible and intolerant). virus resistance was evaluated by viral growth curves and tolerance estimated by morphological and yield components in relation to healthy plants. inoculum pressure effects on resistance/tolerance were also evaluated. brs timbaúva was as susceptible to viral infection as embrapa 16, but in all experiments its productivity loss was lower than that of embrapa 16, which suggests its bydv-pav tolerance. brs timbaúva field behavior may be associated with vector resistance and virus tolerance.
