Abstract: the combination of nitrogen and silicon fertilization, in adequate amounts, can increase rice grains yield and quality. this study aimed at evaluating the yield components, grain yield and milled quality of rice grains, primavera cultivar, according to the application of silicon combined with topdressing nitrogen fertilization, with and without irrigation, in selvíria, mato grosso do sul state, brazil. the experimental design was randomized blocks, in a split-split-plot arrangement, with four replications. the treatments consisted of cropping systems (rainfed and sprinkler irrigation) for plots, silicon doses (0 kg ha-1 and 100 kg ha-1) for split-plots and topdressing nitrogen doses (0 kg ha-1, 30 kg ha-1, 60 kg ha-1 and 90 kg ha-1) for split-split-plots. irrigation increased plant height and grain yield, and the silicon application did not affect grain yield and its components or the milled rice yield of irrigated rice. the rise of n doses, under sprinkler irrigation, increased plant height, number of tillers and panicles m-2 and total spikelets, as well as grain yield, however, for the rainfed system, rice yield decreased.

Abstract: this work was developed with the objective of evaluating the use of trinexapac-ethyl doses (0, 75, 150, 225 and 300 g of the a.i. ha-1) and application times (active tillering, between active tillering and floral differentiation and at floral differentiation) in upland rice crop development and yield. the experiment was carried out in selvíria-ms, during the agricultural year of 2006/07. application of 150 g ha-1 of trinexapac-ethyl in primavera rice cultivar at panicle initiation differentiation reduces plants height, 0.40 m on average comparing to other times, with lodging absence. trinexapac-ethyl promotes lange number of abnormal grains, reduction of grain yields in doses above 150 g ha-1, when applied in panicle initiation differentiation stadium. application of 150 g ha-1 of trinexapac-ethyl at any time does not interfere in crop yield.

Abstract: several works show the efficiency of the nitrogen fertilization in the yield increase common bean yield; however, there is need of new studies, because of the economical point of view, the management of nitrogen that corresponds the largest yield of grains many times it does not correspond to the most profitable and, therefore, it does not fit for recommendation to the producer. the objective of the work was to study the effect of sources, doses and nitrogen split in the development and yield of winter common bean in no tillage system, correlated with a simple economical analysis. the trial was conducted in selvíria county, mato grosso do sul, state, in 2005, in a dystrophic clayey latosol - haplustox. a randomized blocks design was used, in a factorial scheme 3x5x2 with 30 treatments and 4 repetitions constituted by three sources of nitrogen (ammonium sulphate, urea and ammonium sulphate ? of n + urea ? of n), with different doses of nitrogen (0, 50, 100, 150 e 200 kg ha-1) applied at sowing or split (1/3 at sowing + 2/3 v4-4 growth stage). the source of nitrogen from ammonium sulphate provides larger yield of grains of the winter common bean; however, the urea is that provides larger economical efficiency. the increase of the nitrogen fertilization increases the yield up to 198 kg/ha of n, providing on average an increase of 44% in the yield compared with the control (without n). the nitrogen split was not economically viable.

Abstract: the lodging of some rice cultivars, at harvest time, can cause significant losses in grain yield. the use of plant regulators is one of the alternatives to reduce lodging, however, information on that subject are still scarce. this study aimed to evaluate the use of ethyl-trinexapac doses (0 g ha-1, 50 g ha-1, 100 g ha-1, 150 g ha-1, and 200 g ha-1), at the floral differentiation stage, in rice cultivars with different types of plants (caiapó - traditional; brs primavera and brs soberana - intermediate; and iac 202 - modern), in order to evaluate grain development and yield. the experiment was carried out in selvíria, mato grosso do sul state, brazil, during the 2007/2008 growing season. it was observed that the application of 50 g ha-1, 100 g ha-1, and 150 g ha-1 of ethyl-trinexapac, during the floral differentiation stage of the caiapó, brs soberana, and brs primavera cultivars, respectively, decreased plants height and eliminated lodging; it was not necessary to use growth regulator for the iac 202 cultivar, due to its lack of lodging; the application of 50 g ha-1 and 150 g ha-1 of ethyl-trinexapac, during the floral differentiation stage, improved grain yield for the caiapó and brs primavera cultivars, respectively, and the 100 g ha-1 dose interfered little in the brs soberana cultivar.

Abstract: A juventude evangélica brasileira se viu, durante os anos 1970, bombardeada por uma carga considerável de vers es fundamentalistas da escatologia e, com isso, essa quest o veio a ocupar um lugar secundário dentre os temas teológicos dos evangélicos brasileiros. A introdu o de uma perspectiva n o disjuntada da escatologia, como a do teólogo George Eldon Ladd, foi o que possibilitou a difus o da Teologia da Miss o Integral, indicando o quanto a missiologia é inseparável de escatologia. Posteriormente, as vers es fundamentalistas mantiveram um espa o menos popular, mas constante, nas igrejas. O quadro foi acrescido da Teologia da Prosperidade, que trouxe a no o de uma escatologia individualista. Portanto, de um lado temos uma escatologia construída numa perspectiva n o disjuntada do tempo, e do outro uma vis o escatológica fundamentalista e privatizada. O enfrentamento dessas duas tendências expressa a contínua tens o entre o dualismo e a integralidade na história do cristianismo. No Novo Testamento, as imagens da barraca (Jo o 1.14, Atos 18.1-3) e da cortina (Mateus 27.45-52) servem para compreender a dinamica do “habitar entre” em contraste com a do fechamento do sagrado no espa o do haram. Esses dois modos de habitar, na linha de pensamento do filósofo Peter Sloterdijk, ilustram essas duas tendências. Palavras-chave: Juventude Evangélica. Escatologia. Fundamentalismo. Teologia da Miss o Integral. Abstract: Brazilian evangelical youth was, in 1970’s overflowed with a big variety of fundamentalistic versions of eschatology. That’s why this theme came to occupy a secondary place between the others theological themes in Brazilian evangelical Theology. The introduction of a non disjointed version of eschatology, as Georg Eldon Ladd’s, for instance, make possible the diffusion of IMT (Integral Mission Theology), demonstrating how Missiology is inseparable from eschatology. After that, fundamentalistic versions lost their popularity, but kept their presence in churches. Prosperity Theology brought a complete individualistic notion of eschatology. So, we have in one side a eschatology built on a non disjointed notion of time and reality, and in another, the fundamentalistic and privatized version. The clash of these two tendencies expresses the continuous tension between dualism and integrality in the History of Christianity. In the New Testament, the images of the tent (John 1.14, Acts 18.1-3) and of the curtain (Mathews 27.45-52) are useful to understand the logic of “live-between” in opposition with the closeness of the sacred in the haram. These two way

Abstract: A utiliza o de um texto bíblico por um senador para justificar sua oposi o a medidas de prote o ambiental é pretexto para uma série de considera es acerca da Teologia crist sobre o meio-ambiente, e a rela o entre religi o e sociedade. Três quest es s o levantadas: a pretensa separa o dos humanos da natureza, a pretensa homogeneiza o do "ser humano", e a pretensa simplicidade da interpreta o teológica de um texto sagrado. O emprego dos verbos hebraicos KABASH e RADAHA abre uma discuss o sobre o sentido da domina o na teologia crist , a partir do princípio hermenêutico básico de que o todo das Escrituras Sagradas deve ser interpretado à luz da revela o maior em Cristo. A partir daí, o artigo prop e uma articula o de parlamentos, como seria o caso de um parlamento teológico, para tratar de argumentos desse tipo, promovida a partir do Senado Federal para nortear decis es que afetam o bem-estar da sociedade como um todo. Palavras-chave: Ser humano; Natureza; Teologia crist ; Religi o; Sociedade. Abstract The use of a biblical text by a Senator to justify his opposition to environmental protection measures works as a pretext for a series of considerations about Christian theology on environment, as well as the relationship between religion and society. Three questions are to put: the alleged separation of humans from nature, the alleged homogeneity of the "human being", and the assumed simplicity of the theological interpretation of a sacred text. The use of following Hebrew verbs KABASH and RADAHA opens a discussion about the meaning of domination in Christian theology, from the basic hermeneutic principle that Sacred Scriptures must be interpreted in the ligh of Christ Revelation. Thereafter, this article proposes an articulation of parliaments, as in the case of a theological parliament happen to deal with these kind of arguments, to be promoted from the Senate in order to guide decisions that affect the welfare of society as a whole. Key words: Human beings; Nature; Christian Theology; Religion; Society.

Abstract: O artigo procura demonstrar a constru o noticiosa,suas rela es com a sociedade em que é produzida e a História, utilizando-se a de alguns aspectos das coberturas realizadas pela imprensa das guerras da Coréia (1950-53) e do Vietn (1964-73). Considera também os aspectos de conteúdo e forma, desta mesma constru o noticiosa - a notícia n o é apenas conteúdo ou apenas forma, mas ambos, situa o esta que deve ser considerada pelo historiador que trabalhar com a imprensa. The objective of this article is to discuss the construction of media about aspects of the coverage of the wars in Korea (1950-53) and Vietnam in the so called American Phase (1964-73). It states that actually there are two wars: the first one representing the real one with casualties and violence, within military schemes, dangerous situations for both sides in the so called operational theater and the second is the one represented by the media, to be followed by the people. In other words, the first war builds the second war and the second war builds the first war, in a double way relationship. The new technologies make the second war more complex as its representation draws it as near as possible to the first war and the effects on the public become more intense. The presence of the television has also interfered in the war representations.
