En esta intervención se pretende reflexionar acerca de una propuesta que ha ido ganando aceptación en los últimos tiempos: nos referimos al contrato social mujeres y hombres. Así, evocando el contrato social formulado por Rousseau como fundamento para la construcción del Estado, se pretende una nueva reedición del mismo. Un contrato que, se dice, se ha de celebrar entre los dos géneros, y mediante el cual deben fijarse las condiciones para una nueva convivencia social en la que participen por igual los ciudadanos y las ciudadanas.

El presente estudio incorpora el análisis y la sistematizada investigación efectuada a lo largo de su desarrollo, que incluye una descripción general de las nociones fundamentales del Derecho Tributario Internacional conjuntamente con la evolución y los principios básicos de la Fiscalidad Internacional, así también incluye una introducción al concepto de la Doble Imposición y la estructura y la finalidad de los Convenios Internacionales para Evitar la Doble Imposición. Adicionalmente constituye una recopilación de información legal y doctrinaria, compuesta por la opinión de varios de los más connotados juristas y profesores de Derecho a nivel nacional e internacional, respecto a la tributación de los Beneficios Empresariales y al manejo del Establecimiento Permanente en los Convenios Internacionales para Evitar la Doble Imposición y a la legislación nacional. Se trata de una investigación que contempla los aspectos más importantes a tomar en consideración al momento de analizar el concepto y la aplicación del Establecimiento Permanente de acuerdo a nuestra legislación y a lo que establecen los Convenios Internacionales para Evitar la Doble Imposición suscritos con Chile y Uruguay. En cada parte del estudio se pudieron obtener conclusiones importantes, que permitieron el desarrollo adecuado de cada uno de los temas presentados, así como la consecución de los resultados propuestos.

This article examines the conceptual framework and the institutional context of the Geographical Indications and Social Management in Spain on the European Union space. Then, providing a comparative study, Argentina’s and Brazil’s cases are analyzed. The emphasis is on identity and territorial development, where family farming has a central role. Thereafter, public policy drawings and implementation are projected in order to strength concrete agenda and measures elaboration based on Spanish and European experiences’. In both the Argentinean and Brazilian cases, the conclusions point to the need of an adjustment on public policies to better situate and implement actions and objectives. In Brazil the disclosure, financing and strengthening of the Geographical Indications should be bounded to the Programa Territórios da Cidadania, linked to the Ministério do Desenvolvimento Agrário, which is the place of the family farming strengthening policies. In Argentina, with the same logic, the actions should be situated on the Programa Nacional de Apoyo al Desarrollo de los Territórios.

PMN belongs to a special class of materials named relaxor ferroelectrics. It has high volumetric efficiency due to its high dielectric constant, which makes it in a perfect material for application in multilayer capacitors. When prepared the columbite route its preparation has many advantages. In this work, the preparations of columbite and PMN were done by Pechini and Partial Oxalate methods, respectively. The effects of the KNbO3 and LiNbO3 dopants added in various concentrations. The idea is founded on the correlations that they have with BaTiO3 y PbTiO3, respectively. The whole process was supervised by TG/DTA, XRD, SEM and determination of the specific surface area of the powders. LiNbO3 carries out the pre-sinterization of the particles, observed by a reduction in the surface area. There are not particle grow, but occur its lengthening. However, for KNbO3 these particle growth, but the agglomerates are softer. The effect produced by the doping during the synthesis of the PMN powder is different from the one produced in the columbite precursor. Pure precursor shows an average particle size of 0,2μm, but the addition of 5,0mol% of dopants carries out the formation of agglomerates close to 4μm. LiNbO 3 addition carries out spherical particles and pre-sinterization, while KNbO3 addition does not change the particles shape.

The coconut palm crop has increased with the use of the fertigation technique in Brazil in the last years. The objective of this work was to evaluate the influence of N and K rates via fertigation, on vegetative growth of three year old palms, cultivated in the littoral region of the Ceará State, Brazil, with tropical rainy climate. The study was conducted in a sandy soil using the variety of green dwarfed Jiqui coconut palm. The experimental design was a randomized complete block, with 10 treatments, including five nitrogen and five of potassium rates, according to the model of the experimental matrix Plan Puebla III. The nitrogen and potassiun applications via fertigation influenced significantly the plant height, stem perimeter, and the number of leaves and folioles. © 2009 Universidad Centroccidental Lisandro Alvarado (UCLA).

The influence of the type of rotary cutting instrument on bone repair after osteotomy in swine jaw, was evaluated using digital and densitometric radiographic examinations, at controlled times. Two cross-sectional dissections were made through the base of the right jaw, one using a high speed rotary instrument and the other using low speed, both with liquid cooling. After established periods the animals were sacrificed and their jaws removed for direct and indirect digital radiographic and densitometric studies using the CROMOX, DIGORA and ODR systems. In the initial periods (7 and 28 days) the bone density was higher in osteotomy areas performed with high rotation speeds, and in the final periods (60 and 90 days) the bone density was higher in the osteotomies performed with low rotation, indicating a better final bone repair with the use of low rotation. The qualitative analysis of the repair process was made by the ODR system which obtained three-dimensional and coloured digital images, which enable the bone thickness to be measured using an aluminium wedge. This showed that by twenty-eight days the bone repair was already apparently complete. © 2010 SECOM.
