Estudo do aproveitamento integral da planta mandioca

This paper deals with cassava leaf, stem and root production. Field competition trial showed that production of leaves and stems are the same; as that of roots and that leaves and stems can be used in animal feeding beside the industrialization of roots.

Faces em zona e teorema de Cauchy

O presente trabalho tem por objetivo estudar a aplicação do teorema de Cauchy, sobre produto de dois determinantes, às matrizes quadradas de ordem 3, representando zonas cristalograficas.

Tratamento da osteomielite por assepsia integral e penicilina intra-arterial: sutura primitiva e secundária da ferida

Os AA. apresentam dois casos de Osteomilite crônica submetidos durante anos a diversos tratamentos, sem resultado. Pela associação da assepsia integral com a Penicilina intra-arterial (via ainda não usada), conseguiram a cura após sutura primitiva num caso e secundária no outro. Por serem fátos excepcionais acham que devem ficar registrado.

Contractive metrics for a Boltzmann equation for granular gases: diffusive equilibriaThe Patterson-Sullivan embedding and minimal volume entropy for outer space

We quantify the long-time behavior of a system of (partially) inelastic particles in a stochastic thermostat by means of the contractivity of a suitable metric in the set of probability measures. Existence, uniqueness, boundedness of moments and regularity of a steady state are derived from this basic property. The solutions of the kinetic model are proved to converge exponentially as t→ ∞ to this diffusive equilibrium in this distance metrizing the weak convergence of measures. Then, we prove a uniform bound in time on Sobolev norms of the solution, provided the initial data has a finite norm in the corresponding Sobolev space. These results are then combined, using interpolation inequalities, to obtain exponential convergence to the diffusive equilibrium in the strong L¹-norm, as well as various Sobolev norms.

Reflected Backward Stochastic Differential Equation with Jumps and RCLL Obstacle

In this paper we study one-dimensional reflected backward stochastic differential equation when the noise is driven by a Brownian motion and an independent Poisson point process when the solution is forced to stay above a right continuous left-hand limited obstacle. We prove existence and uniqueness of the solution by using a penalization method combined with a monotonic limit theorem.

Hopf bifurcation of a delay differential equation with two delays

We consider a delay differential equation with two delays. The Hopf bifurcation of this equation is investigated together with the stability of the bifurcated periodic solution, its period and the bifurcation direction. Finally, three applications are given.

El pluralisme mèdic: una clau interpretativa per a una història integral de la medicina

El recurs als professionals sanitaris es sols una part de totes aquelles iniciatives, actuacions o creences que els nostres avantpassats van desenvolupar per conservar o millorar la salut, prevenir la malaltia o recuperar la salut. El recurs a altres tipus d'instàncies assistencials o terapèutiques, que es coneix com "pluralisme assistencial", sol ser la norma més que l'excepció. Per a enfocar adequadament aquest problema, cal centrar la indagació històrica sobre aquells -les persones malaltes o sanes- que volien i buscaven la salut. Aquests tipus d'acostaments pretenen tenir en compte totes les possibilitats a les quals es va recórrer en el passat per tal d'afrontar els problemes de salut.

Shelah's singular compactness theorem

We present Shelah’s famous theorem in a version for modules, together with a self-contained proof and some examples. This exposition is based on lectures given at CRM in October 2006.

La Accesibilidad universal en los municipios: guía para una política integral de promoción y gestión

Conscientes de las complejidades que presenta la organización administrativa local y la diversidad que caracteriza a los Ayuntamientos de España, y lejos de querer establecer fórmulas mágicas o generalizar soluciones, con esta Guía se pretende aportar ideas útiles mediante propuestas y algunos ejemplos; con ella se quiere ayudar a promover distintas intervenciones a favor de la accesibilidad en los municipios. En este sentido, esta Guía pretende ser soporte para desarrollar una nueva etapa de intervención municipal en accesibilidad, que vaya más allá de la mera supresión de barreras y se prevenga su creación. Las medidas que se desarrollan son posibles vías para que los gobiernos locales puedan gestionar y promocionar de forma eficaz la accesibilidad en el municipio y así establecer una base sobre la cual todos los ciudadanos puedan desarrollar sus libertades individuales plenamente.
