Natural fibers based composites - Technical and social issues

Brazil is the only country in South America to have an automotive supplier sector based on natural fibers. New opportunities are arising due to an increase demand by the car makers in applying natural fibers in their parts. Several crop fibers have been developed in Brazil. Among them can be listed caroa, piacava, pupunha, mutum and others of regional application. For the automotive industry, which requires large quantities with uniform quality, the alternatives are sisal (170,000 ton/yr), curaua (150 ton/yr in 2003), malva, 200 ton/yr; Brazil is the single largest producer country of sisal, and commercially, the only one in curaua. For South America, the alternatives are fique in Colombia, abaca in equator, flax in Argentina and curaua in Venezuela. It must be understood by the target countries of drugs, is that crop fiber can be an economic alternative to coca in the Andes region, therefore an instrument of land reform and drug reduction plantations. Several companies have a strong program of apply natural fibers based components in their products: Volkswagen do Brazil, DaimlerChrysler, General Motors do Brazil. Among their suppliers can be listed companies such Pematec (curaua), Toro (sisal, coir and jute), Incomer (sisal and jute), Ober (jute, curaua), Indaru (jute and sisal), Antolin (imported kenaf,) Tapetes Sao Carlos (sisal), Poematec (coir) and Art-Gore, with Woodstock'' wood and natural fibers). Figures about production and demand are discussed in the paper.

Análise das interpretações do governo Evo Morales: o legado histórico e o poder nacional-indígena

This work aims to analyze the interpretations about Evo Morales' government in Bolivia. For such, it proposes a theoretical reclaim of Marxism in Latin America, as well as of Bolivian political history since the 1952 Revolution, going through the crisis in Pacted Democracy intensified in the five-year conjuncture of struggles started in 2000 up to the election and reelection of Morales. It departs from an empirical prior conjecture taken from a qualitative analysis and a broad literature review to analyze the different interpretations of the Bolivian political process from Marxist theoretical matrices. After this historical recovery and this reading of contemporary Bolivia, it concludes with a consideration about the formation of a possible new block of power in the country, with the retaking of nationalism and Indianism as revolutionary reasons

El mito, el paisaje y el hombre en la literatura ando-boliviana

This research was based on a study regarding the myth, the landscape and then man in Bolivian literature, a country whose cultural tradition transcends myth and reality, with an exotic nature, inherited from extraordinary people from a remote time, with archeological remains that show its glory, making it particular among other Latin American literatures. To contextualize the literary study of this nation, rich in fantasy literature, understanding its traits in the current literature, we have sought to rescue the history of its first inhabitants, the Kollas, and the cultural reference they inherited and reviewed in the acculturation process between indigenous and Spanish people. This study is based on the contributions of Latin American theorists, such as Antonio Conejo Polar, Nestor Canclini, the Cuban ethnologist Fernando Ortiz, and especially the concept of transculturation of the Uruguayan critic Ángel Rama. Thus, we have tried to rescue a study about the Andean past, approaching the fundamentals of mythic component in literature, addressing landscape and nature as the ones that illustrate, characterize and give life to the mythical characters and social problems of the Andean man

A new species of Miogryllus Saussure, 1877 from Andean Venezuela with bizarre cephalic morphology (Orthoptera, Gryllidae, Gryllinae, Modicogryllini)

Miogryllus muranyi n. sp. is described from the Andean Acacia-Cactaceae semi-desert bush in the Chama Valley of Venezuela. The species is characterized by the unusual shape of the male head, which makes it readily distinguishable from any other congener known to date.

Cogeneration in a solid-wastes power-station: a case-study

Nowadays, natural gas is viewed as the solution to the problem of energy supply for Latin America, Europe and North America for the next few decades; Brazil is increasingly becoming dependent upon the Bolivian natural-gas supply - many industries and some entrepreneurs are deciding to construct industrial cogeneration systems and new thermal power-stations burning natural gas because of its low environmental impact and attractive price. However, natural gas is a finite resource: this will cause, in the future, an increase of its unit price. This paper details questions involved in the energy generation and presents solid-waste burning as a possible alternative fuel for the future, especially in the context of cogeneration practice in which the thermal and electric energy are used primarily for the industries located in an industrial district. Two cogeneration schemes are proposed for the burning of municipal solid wastes, associated or not with natural gas, and their technical and economic feasibilities are examined.

From Plinthic Acrisols to Plinthosols and Gleysols: iron and groundwater dynamics in the tertiary sediments of the upper Amazon basin

Topography has been reported to be the major factor ruling the spatial distribution of Acrisols, Plinthosols and Gleysols on the seasonally flooded, low elevation plateaux of the upper Amazon basin occupied by Tertiary (Ica & Solimoes) sediments. In this study, detailed morphological and mineralogical investigations conducted in a representative 25-ha site were combined with hydro-geochemical data to relate the vertical and lateral soil differentiations observed to the hydro-geological history of that part of the basin. As a result of the uplift of the Andes, several cuts in the extensive Tertiary marshlands have formed, at first, slightly incised plateaux of low elevation. There, weathering under hot and humid climates would have generated a reddish, freely drained and bioturbated topsoil layer and the vertical differentiation in subsoil sediments of a plinthite over an iron-depleted mottled clay. The second episode of soil differentiation is linked to the replacement of the forest by a savannah under the drier climates of the late Pleistocene, which favours surface runoff and the infill of the incisions by fine particles. This infill, combined with the return to the present humid climate, has then enabled the local groundwater to rise on the plateaux and to generate episaturation at the topsoil/subsoil transition close to the depressions. Nowadays, ferrous iron is released from the partly iron-depleted topsoil weathering front at high water levels during the rainy seasons. It moves from footslope to low-lying positions and from top to bottom in the soil profile according to the groundwater dynamics. The present general trend is thus to the lateral export of iron at high water levels due to subsurface and overland flows, its vertical transfer during the recession of the groundwater and accumulation in a nodular plinthite. In the latter, ferrous iron is adsorbed onto its softest iron masses where it feeds the neoformation of ferrihydrite that rapidly dehydrates into haematite.
