Abstract: purpose: to compare sling operations of aponeurosis and tension-free vaginal tape (tvt) for the correction of stress urinary incontinence (sui) regarding: the rates of subjective and objective healing, the mobility of the bladder neck with ultrasonography, the variation of the absorbent test, the urodynamic alterations and the incidence of complications. methods: eighty patients with sui were selected. among them, 61 underwent a tvt surgery and 19, an abdominal rectum sling operation of aponeurosis. average age, index of body mass and parity were 50.1 years old, 29.7 kg/m2 and 4.1 deliveries (median=3) for the patients with aponeurosis sling, and 51.7 years old, 28.1 kg/m2 and 4.1 deliveries (median=3) for the ones with tvt. all of them have undergone anamnesis, physical examination, bladder neck ultrasonography, absorbent test and urodynamic evaluation before and at least six months after the surgery. after 15 or 19 months and after about four or five years, they were again interviewed concerning the surgery results. results: after six months, 96.7% of the women with tvt and 89.5% of the ones with sling thought they were healed in the subjective evaluation. nevertheless, after 15 to 19 months, the tvt group kept the same subjective healing rate, while among the sling group the rate decreased to 77.8%. there was a significant decrease in the mobility of the neck bladder that was similar in both groups and an improvement in the absorbent test. at the end of the urodynamic study, 93.4% of the women from the tvt group and 78.9% of the ones from the sling group were classified as having an objective healing. the average time of bladder probing was higher in the sling group. urinary retention was observed in 42.1% of the sling cases and in 9.8% of the tvt's. the rates of late healing were 90% for tvt and 55.6% for sling. conclusions: tvt surgery provided better subjective healing after 15 or 19 months, but the rate of objective healing was the same in both techniques at

Abstract: objective: retrospective study eveluating the morbid-mortality and hospital behaviour in patients over 70-years -od patients submitted to myocardial revascularization involving the radial artery as the second arterial graft. method: during the period of august 1994 to december 2002, 2487 cases of myocardial revascularization were performed by the group of the juiz de fora heart institute, 476 of whom were 70 years of age or older and 36 (group ii) received the radial artery as the second arterial graft. the same type of surgery was performed in 142 patients under 70-year-old (group i). reoperations, off-pump operations (opcab) or associated procedures were excluded from this study. results: the median age was 72.5 years, the mortality rate was 6% in this group of patients and the incidence of complications was low, comparable to the 142 under 70-year-old patients (group i) submitted to the same type of surgery. conclusion: the resultsachieved with this study lead the authors to believe that the radial artery can be safely used as the second arterial graft in well selected septuagenarian patients, despite the major risk of co-morbidities related to this age.
Selecting Oil Wells for Hydraulic Fracturing: A Comparison between Genetic-Fuzzy and Neuro Fuzzy Systems  [PDF]
Virgílio José Martins Ferreira Filho, Antnio Orestes de Salvo Castro
American Journal of Operations Research (AJOR) , 2014, DOI: 10.4236/ajor.2014.44020

Hydraulic fracturing is widely used to increase oil well production and to reduce formation damage. Reservoir studies and engineering analyses are carried out to select the wells for this kind of operation. As the reservoir parameters have some diffuse characteristics, Fuzzy Inference Systems (FIS) have been tested for these selection processes in the last few years. This paper compares the performance of a neuro fuzzy system and a genetic fuzzy system used for selecting wells for hydraulic fracturing, with knowledge acquired from an operational data base to set the SIF membership functions. The training data and the validation data used were the same for both systems. We concluded that, despite the genetic fuzzy system being a newer process, it obtained better results than the neuro fuzzy system. Another conclusion was that, as the genetic fuzzy system can work with constraints, the membership functions setting kept the consistency of variable linguistic values.

Silva Lusitana , 2009,
Abstract: the herbaceous biomass was evaluated in quercus pyrenaica woodlands in two seasons (spring and autumn) for three consecutive years (1999, 2000 and 2001), both in grazed and non-grazed areas. for this, we used the method of clipping and weighing, in 0.25 m side plots in both areas (10 and 9 quadrates of grazed and non-grazed land, respectively). this procedure was repeated in four black oak woodlands (freixedelo, sortes, rebordainhos and zido), all located in different environments and with different structures. the results show differences in the accumulated biomass among the various locations, seasons, years, and among the grazed and non-grazed plots. evidence shows the positive interaction between the wood and animal components, an essential condition for the silvopastoral approach in the management of these systems.

Abstract: initially this article revises some of the conceptual and operational elements on evaluative research by gathering knowledge and action fields on public health practices. such concepts are taken according to a wider conception of quality. then, the article intends to arrange a theoretical model design considering the proposition for implementation of health surveillance actionsan image-objective definition of organization and integration of health polices and practices based on hierarchic and local logic also take place. finally, becomings and challenges around the theory in the health evaluation field turn to be the aim of our reflection in order to enable the production of knowledge and approaches to construct logic models which reveals the complexity of interventionist objects as well as its transforming nature of social practices.

Abstract: the researched region, located in ecological tension area, was subjected to geo-environmental compartmentalization of its units, according to presupposed geo-systemic theories. the vegetation, in "cerrado island around termite hills", configures physiognomic types with abrupt or gradual contacts, installing themselves in soils subjected to lateritization and ironization processes. the relations between soil, vegetation, structure, floristic and diversity were analysed in 8 parcels (20m x 50m, each).
Aspectos genéticos da actividade física. Estado actual do conhecimento baseado nos modelos animal e humano com amostras gemelares
Maria Madalena Castro Oliveira,José Antnio Ribeiro Maia
Movimento , 2002,
Abstract: Physical activity is a behaviour associatedto quality oflife andlongevity. This phenotype presents variation at the population levei whose main determinants studiedare, essentially, socio-economic, demographic and psychological. Yet, expkined variance of thes determinants is very low(<30%). A mainpart of the total variance of this phenotype has to be associated with another fundamental agent -the phenotype. The work we are presenting wants to review, in an exhaustive way, animal and human research with the twin methodology. Main research has dealt with three different expressions ofthe phenotype physical activity - total physical activity, sports participation andenergy expenditure. From the results emerges clearly the importance of genetic feature in the interindividual variation of physical activity at the population levei, whosemain effect centres around 50 -70%.
Respostas de indivíduos jovens de Tibouchina pulchra Cogn. à polui??o aérea de Cubat?o, SP: fotossíntese líquida, crescimento e química foliar
Brazilian Journal of Botany , 2000, DOI: 10.1590/S0100-84042000000400010
Abstract: saplings of tibouchina pulchra, cultivated on standardised conditions, were placed in three sites at the cubat?o region to study the effects of the air pollutants on photosynthesis, growth and leaf concentrations of ascorbic acid, chlorophyll, nitrogen, sulfur and fluoride. the study areas were: pil?es river valley (rp), considered as the reference plot; caminho do mar (cm), near the petrochemical industries; and mogi river valley (vm), near metallurgical and fertilizer industries. four plants remained in each plot during six months. compared to the reference plot (rp - 9.81 mmol.m-2.s-1), net photosynthesis was reduced (p < 0.05) in plants at the vm site (8.02 mmol.m-2.s-1), and it was not altered in the other area (cm - 9.29 mmol.m-2.s-1). plants grown in vm showed reduction in height and the amount of ascorbic acid, alterations on the pattern of biomass distribution in the plant, increased concentrations of chlorophyll a and b, fluoride, nitrogen and sulfur. plants exposed in cm showed reduction in both height and diameter, and enhanced concentrations of chlorophyll a and b, fluoride, n and s. the results indicate that pollutant concentrations have still been at phytotoxic levels in vm and cm and this problem was more intensive in vm, during the exposure period.
Respostas de indivíduos jovens de Tibouchina pulchra Cogn. à polui o aérea de Cubat o, SP: fotossíntese líquida, crescimento e química foliar
Brazilian Journal of Botany , 2000,
Abstract: Indivíduos jovens de Tibouchina pulchra, cultivados em condi es padronizadas, foram colocados em três regi es de Cubat o para estudo dos possíveis efeitos dos poluentes aéreos sobre a fotossíntese, o crescimento e as concentra es foliares de ácido ascórbico, clorofila, nitrogênio, enxofre e flúor. As áreas de estudo foram: vale do rio Pil es (RP), considerada área de referência; Caminho do Mar (CM), próxima a indústrias petroquímicas e vale do rio Mogi (VM), próxima a indústrias siderúrgicas e de fertilizantes. Quatro plantas permaneceram em cada área por um período de seis meses. Em compara o com as plantas mantidas na área de referência (RP - 9,81 mimol.m-2.s-1), a fotossíntese líquida foi reduzida (p < 0,05) nas plantas que foram mantidas em VM (8,02 mimol.m-2.s-1), e n o foi alterada em CM (9,29 mimol.m-2.s-1). Em VM, as plantas apresentaram redu o do crescimento em altura e do conteúdo de ácido ascórbico, altera o no padr o de distribui o de biomassa entre as partes da planta e aumento das concentra es foliares de clorofila a e b, flúor, nitrogênio e enxofre. As plantas de CM apresentaram redu o no crescimento em altura e diametro, aumento nas concentra es foliares de clorofila a e b, flúor, nitrogênio e enxofre. Os resultados obtidos indicam que as concentra es de poluentes ainda se encontram em níveis fitotóxicos em CM e VM, tendo sido mais altas em VM, durante o período de exposi o.

Abstract: mortality due to external causes is the second leading cause of death in brazil. few studies addressing this issue have been conducted in the northeast of the country, or in maranh?o, state whose mortality rate due to external causes is one of the lowest in brazil. this paper aims at examining trends in mortality due to external causes in s?o luís, from 1980 to 1999 and verifying if this trend differs for those observed for the country as a whole and for other brazilian cities. the external causes were surveyed in accordance to the 9th revision of the international classification of diseases (icd) from 1980 to 1995 and the 10th revision was used from 1996 to 1999. special coding was used to assure comparability between the two icd revisions. trend analysis was performed using a poisson regression model. mortality by external causes showed a significant overall reduction, for both sexes, and in the 0-9, 30-39 and 40-49 age groups. mortality by transportation accidents, other accidents and unknown causes reduced significantly, whereas mortality by homicides and suicides showed a highly significant increase. this decreasing trend in mortality due to external causes is in agreement with recent observations made for the country as a whole, for the americas and for the city of s?o paulo.
