Abstract: examined a set of mothers' descriptions and understandings of family values and behaviors across three generations. the informants were twelve mothers, from four different families, following a generational linearity of grandmother, mother and granddaughter. all of them were residents in the area of passo fundo/rs. by using a qualitative analysis based on a phenomenological theory, the continuities and discontinuities of behavior and ideas were interpreted in two perspectives: 1) new arrangement in the power of father and mother and in the family cohesion and 2) changing from collective to personal identity with an increasing in the space for self realization. continuities were related to general principles as family ethics. in contrast, discontinuities happened according to contextual pressures in the practical aspects of family life.
Estimating Stocks Return with Decomposition of the Book-to-Market Ratio: Evidences from Bovespa
Juliano Ribeiro de Almeida,William Eid Jr.
Revista Brasileira de Finan?as , 2010,
Abstract: The book-to-market (BM) ratio differs across stocks because to differences in expected cashflows and expected returns. The central hypothesis is that the evolution of BM, in terms of past changes in price and book equity, contains information about future cashflows that can be used to improve estimates of expected returns. This article used a database of Economática to extract a sample of non-financial companies shares listed on BOVESPA and test this hypothesis. The estimated regressions were performed monthly during the period July 1996 to June 2008. Both for large and mid caps as for small caps, the results do not favor this hypothesis and show that only the most recent BM is important to predict the assets returns. Furthermore, stock issues and repurchases are also related to future cashflows and it is expected to improve estimates of expected returns. However, the results provide no evidence favoring that.
Relativistic Cosmology Number Counts and the Luminosity Function
Marcelo B. Ribeiro,William R. Stoeger
Physics , 2003, DOI: 10.1086/375717
Abstract: This paper aims to connect the theory of relativistic cosmology number counts with the astronomical data, practice, and theory behind the galaxy luminosity function (LF). We treat galaxies as the building blocks of the Universe, but ignore most aspects of their internal structures by considering them as point sources. However, we do consider general morphological types in order to use data from galaxy redshift surveys, where some kind of morphological classification is adopted. We start with a general relativistic treatment for a general spacetime, and then link the derived expressions with the LF definition adopted in observational cosmology. Then equations for differential number counts, the related relativistic density per source, and observed and total relativistic energy densities of the universe, and other related quantities are written in terms of the luminosity and selection functions. As an example of how these theoretical/observational relationships can be used, we apply them to test the LF parameters determined from the CNOC2 galaxy redshift survey, for consistency with the Einstein-de Sitter (EdS) cosmology, which they assume, for intermediate redshifts. We conclude that there is a general consistency for the tests we carried out, namely both the observed relativistic mass-energy density, and the observed relativistic mass-energy density per source, which is equivalent to differential number counts, in an EdS Universe. In addition, we find clear evidence of a large amount of hidden mass, as has been obvious from many earlier investigations. At the same time, we find that the CNOC2 LF give differential galaxy counts somewhat above the EdS predictions, indicating that this survey observes more galaxies at 0.1 < z < 0.4 than the model's predictions.

Revista Brasileira de Ginecologia e Obstetrícia , 2012, DOI: 10.1590/S0100-72032012000600007
Abstract: purpose: to evaluate the anatomical distribution of deep infiltrating endometriosis (die) lesions in a sample of women from the south of brazil. methods: a prospective study was conducted on women undergoing surgical treatment for die from january 2010 to january 2012. the lesions were classified according to eight main locations, from least serious to worst: round ligament, anterior uterine serosa/vesicouterine peitoneal reflection, utero-sacral ligament, retrocervical area, vagina, bladder, intestine, ureter. the number and location of the die lesions were studied for each patient according to the above-mentioned criteria and also according to uni- or multifocality. the statistical analysis was performed using statistica version 8.0. the values p<0.05 were considered statistically significant. results: during the study period, a total of 143 women presented 577 die lesions: uterosacral ligament (n=239; 41.4%), retrocervical (n=91; 15.7%), vagina (n=50; 8.7%), round ligament (n=50; 8,7%), vesico-uterine septum (n=41; 7.1%), bladder (n=12; 2.1%), and intestine (n=83; 14.4%), ureter (n=11; 1.9%). multifocal disease was observed in the majority of patients (p<0.0001), and the mean number of die lesions per patient was 4. ovarian endometrioma was present in 57 women (39.9%). sixty-five patients (45.4%) presented intestinal infiltration on histological examination. a total of 83 die intestinal lesions were distributed as follows: appendix (n=7), cecum (n=1) and rectosigmoid (n=75). the mean number of intestinal lesions per patient was 1.3. conclusions: die has a multifocal pattern of distribution, a fact of fundamental importance for the definition of the complete surgical treatment of the disease.
Spontaneous Healing of a Rectovaginal Fistula Developing after Laparoscopic Segmental Bowel Resection for Intestinal Deep Infiltrating Endometriosis
William Kondo,Reitan Ribeiro,Carlos Henrique Trippia,Monica Tessmann Zomer
Case Reports in Obstetrics and Gynecology , 2013, DOI: 10.1155/2013/837903
Abstract: The surgical treatment of intestinal deep infiltrating endometriosis has an associated risk of major complications such as dehiscence of the intestinal anastomosis, pelvic abscess, and rectovaginal fistula. The management of postoperative rectovaginal fistula frequently requires a reoperation and the construction of a stoma for temporary fecal diversion. In this paper we describe a 27-year-old woman undergoing laparoscopic treatment of deep infiltrating endometriosis (extramucosal cystectomy, resection of the uterosacral ligaments, resection of the posterior vaginal fornix, and segmental bowel resection) complicated by a rectovaginal fistula, which healed spontaneously with nonsurgical conservative treatment. 1. Introduction Intestinal deep infiltrating endometriosis (DIE) is defined as lesions involving at least the muscularis propria of the bowel [1]. It affects up to 45.4% of women with DIE lesions [2, 3] and may be found at any level from the anal verge to the small intestine; however, the most frequent sites of involvement are the rectum and the sigmoid colon [3–6]. The management of intestinal DIE lesions may be medical and/or surgical. Medical treatment plays a substantial role in terms of pain relief in women with rectovaginal endometriosis; however it has a temporary effect [7]. Surgical treatment combines different procedures according to the anatomical distribution of the lesions [1, 3]. There are different surgical techniques to approach the intestinal DIE: rectal shaving, mucosal skinning, disc resection, and segmental bowel resection (with or without protective ileostomy). The choice for the procedure depends on several factors, such as (1) size of the lesion, (2) percentage of the circumference of the bowel involved by the lesion, (3) presence of multifocal lesions, and (4) distance between the anal verge and the intestinal DIE lesion [8–11]. No matter which type of rectal surgery is selected, there is an associated risk of major complications such as dehiscence of the intestinal anastomosis, pelvic abscess, and rectovaginal fistula [12–16]. The latter is a catastrophic complication of such intervention because it may drastically alter patient’s self-esteem and intimate relationships and may lead to significant psychosocial and sexual dysfunction [17, 18]. The management of this situation is not easy and frequently requires a reoperation and the construction of a stoma for temporary fecal diversion. The aim of this paper is to report one case of spontaneous healing of a rectovaginal fistula developing after laparoscopic segmental bowel
Radial Density Statistics of the Galaxy Distribution and the Luminosity Function
Alvaro S. Iribarrem,Marcelo B. Ribeiro,William R. Stoeger
Physics , 2012,
Abstract: This paper discusses a connection between the relativistic number counts of cosmological sources and the observed galaxy luminosity function (LF). Observational differential number densities are defined and obtained from published LF data using such connection. We observe a distortion in the observational quantities that increases with higher redshift values as compared to the theoretical predictions. The use of different cosmological distance measures plays a role in such a distortion

Abstract: background: hepatocellular carcinoma is one of the major malignant diseases in the world today. due to the high incidence and difficult prognosis, preventive measures became an important need taking into consideration that its etiology is strictly connected with environmental factors. the main risk factors are the association of hepatocellular carcinoma with chronic hepatitis b and c virus infections and cirrhosis, whatever its cause. hepatocellular carcinoma is the fifth most common global cancer, representing 85% of the hepatic primary tumors and it is responsible for nearly two thirds of deaths caused by cancer.method: review of the national and international literature in the last 12 years (1997-2009), of 25 articles researched through the electronic databases medline, scielo and lilacs. conclusion: despite of the medical advances and the implementation of precocious measures to detect the hepatocellular carcinoma in patients considered as within risk groups, there was no improvement on the afterlife over the last three decades. the cause that can explain this reality is the absence of symptoms during the early stages of the disease, and by the time the patient looks for medical help, the tumor has frequently reached an advanced stage and the therapeutical options are already too few.

Abstract: the purpose of this study was to assess the effectiveness of nasopalatine nerve block for anesthesia of maxillary central incisors after failure of the anterior superior alveolar nerve (asan) block technique. secondarily, the possible innervation of the maxillary central incisors by the nasopalatine nerve was also investigated. twenty-seven healthy, young adult volunteers (age: 17-26 years; gender: 9 males and 18 females) were enrolled in this study. all participants were undergraduate dental students of the university of vale do rio verde de três cora??es. the volunteers had the anterior superior alveolar nerves anesthetized and a thermal sensitivity test (cold) was performed on the maxillary central incisors. the volunteers that responded positively to cold stimulus received a nasopalatine nerve block and the thermal sensitivity test was repeated. all participants were anesthetized by a single operator. three patients presented sensitivity after both types of bilateral blocks and were excluded from the percentage calculations. in the remaining 24 patients, 16 had their maxillary central incisors anesthetized by the anterior superior alveolar block and 8 remained with sensitivity after the asan block. all these 8 patients had their maxillary central incisors successfully anesthetized by the nasopalatine block. in this study, 33.3% of the subjects had the innervation of one or both maxillary central incisors derived from the nasopalatine nerve, whilst most subjects (66.7%) had such teeth innervated by the anterior superior alveolar nerve. the nasopalatine nerve block was effective in anesthetizing the maxillary central incisors when the anterior superior alveolar nerve block failed.
