Este estudio representa la primera reseña global del riego en el departamento de Rivas. Se presenta primero una lista exhaustiva de todas las fincas que utilizan riego en los últimos años. Esta lista se utiliza para escoger una muestra de fincas con riego, que están estudiadas más precisamente, con el fin de realizar allí en diagnóstico del riego. Particularmente, se hace énfasis en la comparación entre la dosis y frecuencias utilizadas en las fincas, y las dosis y frecuencias recomendables. Se precisa ampliamente la metodología utilizada para determinar los elementos teóricos fundamentales del riego en cada finca. En fin, se presentan recomendaciones de mejoría del riego, tanto en las fincas estudiadas, como a nivel del departamento.

Se estudió la adaptación de fabáceas a suelos veticos y vertésoles en sabanas de crescentia alata hbk. Se establecieron dos experimentos en terreno de jícaro, s.a., km152 telica san isidro, los zarzales, león. El diseño usado fue bloques completos al azar, con 3 replica y accesiones como tratamiento. Se sembró en hileras, con parcela útil de 1 m2. Los factores evaluados fueron: germinación, cobertura, altura de plantas, daños por plagas y enfermedades, nodulacion, floración y cuando fue posible biomasa (Mv y Ms) El ensayo (1985-1986) se realizó con 10 accesiones, mejoradas y nativas, en parcelas experimentales de 3.75m2 adicionalmente se observaron 2 réplicas con siembra al voleo y sin control de male3zas; una y la otra sin rotulación de suelo. El ensayo (1987) constaba con 25 accesiones introducidas del CIAT a través del programa forrajero, DGA, madrina, con parcela experimentales de 12.5m2. El género centrosema presento excelente adaptación de especies: c.brasilianum (3 accesiones), c.pubescens (mejorada y nativa) y c.macrocaroum (1 accesión). Sobresalieron las especies dolichos 1ab-1ab, pueraria phaseoloides (ambas introducidas) y calopogonium galantoides (nativa). También están: macroptilium atropurpureum (cv. Siratro nativa), aeschynomene americana: sufrutice resistente a enfermedades y anegamiento, pero con biomasa lignificada y desmodium glabrum de buen porte y biomasa apetecible. En el transcurso experimental se observó que el suelo anegado propicia enfermedades fungosas en accesiones trepadoras; soporte mecánico disminuye ataques. Siembra al voleo en suelos rotulados y sin control de malezas es factible para establecer fabáceas de “primera”.

Methane hydrate, which is usually found under deep seabed or permafrost zones, is a potential energy resource for future years. Depressurization of horizontal wells bored in methane hydrate layer is considered as one possible method for hydrate dissociation and methane extraction from the hosting soil. Since hydrate is likely to behave as a bonding material to sandy soils, supported well construction is necessary to avoid well-collapse due to the loss of the apparent cohesion during depressurization. This paper describes both physical and numerical modeling of such horizontal support wells. The experimental part involves depressurization of small well models in a large pressure cell, while the numerical part simulates the corresponding problem. While the experiment models simulate only gas saturated initial conditions, the numerical analysis simulates both gas-saturated and more realistic water-saturated conditions based on effective stress coupled flow-deformation formulation of these three phases. © 2006 Taylor & Francis Group.

A formulation for coupled flow-deformation analysis of methane-hydrate extraction problems is presented. By assuming that the hydrate does not flow, a two phase flow formulation is considered, based on Darcy's law and capillary pressure relation. The formulation is implemented in the finite difference code FLAC. The code was used to investigate the stability of a methane extraction well by depressurizing the well. © 2005 Taylor & Francis Group, London.

Analisa os discursos sobre sistemas de governo na Assembleia Nacional Constituinte que formulou a Constituição Brasileira de 1988. Tem como objetivo encontrar os principais aspectos que orientaram os discursos de parlamentaristas e presidencialistas, e as estratégias discursivas utilizadas. Para isso, apresenta as principais características de cada um dos sistemas e o contexto histórico no qual a Constituinte estava inserida.

One of the causes of lower artesian pressure, water waste and aquifer contamination is the misuse and insufficient care of artesian wells. In 1953, Senate Bill No. 57, entitled "An Act to Protect and Control the Artesian Waters of the State" (see Appendix) became a law. This law was passed through the efforts exerted by leading members of the Senate and the House of Representatives, who understood the need for a wise and controlled expenditure of our most valuable natural resource. The State Geologist and his authorized representatives were designated by this law to enforce this conservation measure; however, no financial provision was included for the 1953-55 biennium. The proposed program of the Florida Geological Survey for this biennium did not include the funds nor provide any full-time personnel for the enforcement of this statute. As a result, little actual work was accomplished during these two years, although much time was given to planning and discussion of the problem. Realizing that this program could provide additional basic data needed in the analysis of the water-supply problem, the State Geologist sought and was granted by the 1955 Legislature adequate funds with which to activate the first phase of the enforcement of Florida Statute No. 370.051-054. Enumerated below is a summary of the progress made on this investigation as outlined previously: 1. Data have been collected on 967 wildly flowing wells in 22 counties. 2. Chloride determinations have been run on 850 of the 967 wells. 3. Of the 967 wells, 554 have chlorides in excess of the 250 ppm, the upper limit assigned by the State Board of Health for public consumption. 4. Water escapes at the rate of 37, 762 gallons per minute from these 967 wells. This amounts to 54, 377, 280 gallons per day. The investigation is incomplete at this time; therefore, no final conclusions can be reached. However, from data already collected, the following recommendations are proposed: 1. That the present inventory of wildly flowing wells be completed for the entire State. 2. That the current inventory of wildly flowing wells be expanded at the conclusion of the present inventory to include all flowing wells. 3. That a complete statewide inventory program be established and conducted in cooperation with the Ground Water Branchof the U.S. Geological Survey. 4. That the enforcement functions as set down in Sections 370.051/.054, Florida Statutes, be separated from the program to collect water-resource data and that these functions be given to the Water Resources Department, if such is created (to be recommended by the Water Resources Study Commission in a water policy law presented to the 1957 Legislature). 5. That the research phase (well inventory) of the program remain under the direction of the Florida Geological Survey. (PDF contains 204 pages.)

A detailed study of the geology and ground-water resources of the Ruskin area (fig. 1) was made during the period from 1950 to 1955, by the U. S. Geological Survey in cooperation with the Florida Geological Survey and the Board of County Commissioners of Hillsborough County. The results of this study are given in a report by Harry M. Peek entitled "The artesian water of the Ruskin area of Hillsborough County, Florida" and published by the Florida Geological Survey as Report of Investigations No. 21. This report contains tables of well records that were compiled from data collected during that investigation. The well-numbering system used in the tables is based on latitude and longitude.
