Paniculite mesentérica: aspectos na tomografia computadorizada
Moreira, Luiza Beatriz Melo;Pinheiro, Ricardo Andrade;Melo, Alessandro Severo Alves de;Alves, José Ricardo Duarte;Noro, Fabio;Marchiori, Edson;
Radiologia Brasileira , 2001, DOI: 10.1590/S0100-39842001000300004
Abstract: mesenteric panniculitis is an inflammatory process that represents the second stage of a rare progressive disease involving the adipose tissue of the mesentery. imaging methods used in the diagnosis of mesenteric panniculitis include barium studies, ultrasonography, computed tomography and magnetic resonance imaging. computed tomography is important for both, diagnosis and evaluation of the extension of the disease and treatment monitoring. computed tomography findings may vary according to the stage of the disease and the amount of inflammatory material or fibrosis. there is also good correlation between the computed tomography and anatomical pathology findings. the authors studied 10 patients with mesenteric panniculitis submitted to computed tomography. magnetic resonance imaging was also performed in one patient. in all patients, computed tomography revealed a heterogeneous mass in the mesentery with density of fat, interspersed with areas of soft tissue density and dilated vessels.

Abstract: epiploic appendicitis is an uncommon inflammatory condition, which is presently better diagnosed by current imaging methods such as computed tomography and ultrasonography that allow a non-invasive and efficient diagnostic approach. the authors studied 6 patients with epiploic appendicitis. the patients were submitted to computed tomography that showed paracolic oval lesions of 1 to 2 cm of diameter, fat attenuation and a thin peripheral hyperdense rim associated with adjacent fat stranding. ultrasound examination performed in two patients showed hyperechoic ovoid noncompressible masses at the site of maximum abdominal tenderness.

Seed reserves partition and light compensation point of mahogany (Swietenia macrophylla King) seedlings growth under low photosynthetic active radiation
Lemos Filho, José Pires de;Duarte, Ricardo Jenner;
Brazilian Archives of Biology and Technology , 1998, DOI: 10.1590/S1516-89131998000200006
Abstract: the aim of this study was to verify the dry mass partition of the seed reserves during the initial growth of swietenia macrophylla seedlings, in the dark, and at low levels of photosynthetically active radiation: 0.125; 3.12 and 52 μ mol.m-2.s-1. after 50 days, the dry mass of the seed reserves did not differ with treatments, but the total dry mass and leaf area were higher in the seedlings under higher light treatment. no difference in root/shoot ratio was observed between treatments, but the leaf area ratio was lower at higher light. only the seedlings grown at 52 μ mol.m-2.s-1 showed a positive dry mass increase in relation to the mobilized seed reserves. with the values of the net increase of the seedling mass, a linear equation was adjusted in relation to the light levels, permitting to determine 3.76 μ mol.m-2.s-1 as the seedling light compensation point. these results explain the shade tolerance of the s. macrophylla seedlings.
Uma proposta para a modelagem do valor percebido na presta??o de servi?os
Silva, Paulo Ricardo Ckless;Ribeiro, José Luis Duarte;
Produ??o , 2002, DOI: 10.1590/S0103-65132002000100003
Abstract: this paper presents a proposal for modeling the perceived value associated to a service. once the perceived value is known, it is possible to perform a comparison with the corresponding costs. this comparison forms the base for the establishment of an improvement plan and allows the prioritization of the activities showing higher profitability. the proposed model is illustrated through a case study conducted on the personal computers maintenance sector.
Estrutura Microfísica das Nuvens em Diferentes Ecossistemas da América do Sul.
Bruno Muniz Duarte,José Ricardo de Almeida Fran?a
Anuário do Instituto de Geociências , 2009,
Abstract: Clouds directly affect meteorological conditions of the planet, by interacting with electromagnetic radiation from the sun, the earth’s surface and the atmosphere. Each cloud type interacts in a particular way, being extremely important that the total set of clouds at any location is well represented in atmospheric models, in order to generate more accurate results. The purpose of this paper is to initiate a characterization of cloud types as a function of their microphysical properties and evaluate the dependence on ecosystem and synoptic condition. The data were obtained through remote sensing, using the MODIS sensor and the variables: cloud particle effective radius, optical thickness, pressure and temperature of the cloud top. Several forms of distributions were found for six different ecosystems for the four seasons. It was noted that narrow and concentrated effective radius spectra are linked to deep convection clouds, while broader distributions can be usually associated to cold frontal systems. The amount of events analyzed was not enough to show clear patterns, although the results can lead to other directions in a future and more focused work.
La década de los fondos de pensiones en los países latinoamericanos
José Ricardo Duarte Ojeda,Carlos Cebarut Elizalde Sánchez
Revista Venezolana de Análisis de Coyuntura , 2011,
Abstract: Derivado de las reformas implementadas a los sistemas de pensiones latinoamericanos, inicialmente en Chile durante 1981 y, que continuaron a lo largo de las siguientes dos décadas, los fondos de pensiones han observado un crecimiento notable convirtiéndose en una de las fuentes de ahorro nacional más determinantes para el crecimiento de las economías. Otro aspecto determinante lo constituyen las empresas financieras denominadas Administradoras de Fondos de Pensiones, especializadas en la gestión de los fondos de pensiones, las cuales dominan internacionalmente este mercado manifiesto en la obtención de grandes utilidades y otros beneficios financieros. Este trabajo revisa concretamente el desempe o de los sistemas de pensiones a través de medir los trabajadores afiliados y cotizantes, activos financieros, rendimientos y comisiones así como, concentración del sistema por parte de las AFP multinacionales en el periodo de 1997 a 2010.

Moreira Luiza Beatriz Melo,Pinheiro Ricardo Andrade,Melo Alessandro Severo Alves de,Alves José Ricardo Duarte
Radiologia Brasileira , 2001,
Abstract: A paniculite mesentérica é um processo inflamatório que constitui o segundo estádio de uma doen a rara e progressiva que envolve o tecido adiposo do mesentério. Entre os métodos radiológicos utilizados no diagnóstico est o os estudos baritados, a ultra-sonografia, a tomografia computadorizada e a ressonancia magnética do abdome. A tomografia computadorizada tem importancia tanto no diagnóstico e avalia o da extens o da doen a quanto no planejamento do tratamento, e os aspectos tomográficos variam de acordo com o estádio da doen a e se o componente predominante é inflamatório ou fibroso, tendo boa correla o com os achados da anatomopatologia. Os autores estudaram dez casos de paniculite mesentérica submetidos a tomografia computadorizada, sendo que em um deles foi realizada ressonancia magnética. Em todos os casos o aspecto tomográfico era o de forma o expansiva heterogênea, com densidade predominantemente adiposa, apresentando vasos ectasiados e bandas lineares com densidade de partes moles de permeio, localizada no mesentério.

Silveira, Flávio José Magalh?es da;Duarte, Ricardo Luiz de Menezes;
Jornal Brasileiro de Pneumologia , 2010, DOI: 10.1590/S1806-37132010001400009
Abstract: in some studies, snoring has been associated with an increased risk of hypertension, ischemic heart disease and stroke. although the mechanisms involved in these associations are unknown, they are probably mediated by obstructive sleep apnea. nevertheless, most snorers do not have sleep apnea. whether snoring itself increases the risk of cardiovascular disease remains controversial.
