Abstract: Inevitable say that the Brazilian Constitution of 1988 refl ects an existing reality in our nation. Also notorious that its origin brought a not too distantpast, inserted into your body experiences that have brought benefi ts to society are still there. The constitutional development was necessary for Brazil to move forward, and from this perspective, we will study important aspects of theImperial Constitution of 1824, the fi rst constitution in our country soon after the cessation of colonial Brazil, and who translated the strong features of the European elite, where slavery was still existing. The centralization of power at that time answers many questions about the Constitution currently in force, which reveals more freedom with regard to fundamental rights of citizens, existing in its minimum degree in another letter undemocratic. Analysis, therefore, these two moments.

Abstract: the objective was to undertake a careful review of a consecutive series of 120 patients with colorectal cancer approached by laparoscopic surgery (video-group, 60 patients) and by laparotomy (lap-group, 60 patients), during 12 months (may 2009 to may 2010). the average age was 58 years and 58.8 years in group-lap and 57.3 years in video-group, the majority being females in both groups (lap-group - 55.0% and video-group - 61.7%, general mean 58.3 years). all patients in both groups underwent colonoscopy and biopsy with histopathologic diagnosis of adenocarcinoma. as far as distribution of tumors in the large intestine in lap-group, 43 tumors were located in the rectum, rectosigmoid and sigmoid colon (71.7%) versus 45 in video-group (75.0%), but with differences between low rectum (lap-group 13,3%, video-group 16.7%) and upper rectum (lap-group 30.0%, video-group 16.7%), sigmoid and rectosigmoid (lap-group 28.4%, video-group 41.6%). the most performed surgery was abdominal rectosigmoidectomy (lap-group 27 cases, 45.0%; and video-group 33 cases, 55,0%), followed by right hemicolectomy (lap-group 16 cases, 26,6%; and video-group 13 cases, 21.7%). the extensions of the surgical specimens were greater in lap-group (mean 46.1 cm vs. 30.0 cm in video-group), but due to higher number of surgeries that resulted in longer specimens. when comparing same surgical techniques, the difference does not persist as in cases of retosigmoidectomy (lap-group with 32 cases, mean 28.2 cm; and video-group with 39 cases, mean 26.6 cm). with regard to tnm staging t3n0m0, tumors was the most common in lap-group with 30 cases (50.0%) and video-group with 35 cases (58.4%). regarding the lymph nodes count in surgical specimens, no difference was noted: total of 810 lymph nodes in specimens of lap-group with a mean of 13.5 nodes per specimen, and total of 862 lymph nodes in video-group with an average of 14.3 nodes per specimen. no difference was noted in relation to the count of lymph nodes in su
Chemometrics Approaches in Forced Degradation Studies of Pharmaceutical Drugs

Abstract: Chemometrics is the chemistry field responsible for planning and extracting the maximum of information of experiments from chemical data using mathematical tools (linear algebra, statistics, and so on). Active pharmaceutical ingredients (APIs) can form impurities when exposed to excipients or environmental variables such as light, high temperatures, acidic or basic conditions, humidity, and oxidative environment. By considering that these impurities can affect the safety and efficacy of the drug product, it is necessary to know how these impurities are yielded and to establish the pathway of their formation. In this context, forced degradation studies of pharmaceutical drugs have been used for the characterization of physicochemical stability of APIs. These studies are also essential in the validation of analytical methodologies, in order to prove the selectivity of methods for the API and its impurities and to create strategies to avoid the formation of degradation products. This review aims to demonstrate how forced degradation studies have been actually performed and the applications of chemometric tools in related studies. Some papers are going to be discussed to exemplify the chemometric applications in forced degradation studies. View Full-Tex

Araujo Junior, Ari Francisco de;Shikida, Claudio;Alvarenga, Patrícia Silva;
Revista de Economia e Sociologia Rural , 2008, DOI: 10.1590/S0103-20032008000300009
Abstract: the article analyzes the determinants of the probability of dispute over land (conflicts, occupations and settlement projects) in the brazilian state of minas gerais. through the use of a logit model, we found that the main influences are political and economical ones. apparently, the behavior of the agrarian reform's supporters follows the political incentive, with fewer occurrences of conflicts in towns governed by political allies. by other hand, the economical determinants - degree of poverty and the economic growth - have negative impacts on it.
A weight restricted DEA model for FMEA risk prioritization
Pauli Adriano de Almada Garcia,Ilton Curty Leal Junior,Murilo Alvarenga Oliveira
Produ？？o , 2012, DOI: 10.1590/s0103-65132012005000092
Abstract: In this paper we present a linear programming (LP) approach to risk prioritization in failure mode and effects analysis (FMEA). The LP is a data envelopment analysis (DEA)-based model considering weight restriction. In a FMEA, we commonly consider three criteria to prioritize the failure modes, occurrence, severity and detectability. These criteria are in an ordinal scale commonly varying from 1 to 10, higher the figure worse the result. Considering the values established for each criteria, in traditional FMEA one adopts a Risk Priority Number, calculated considering the product of criteria, which has been very criticized due to its shortcoming. Through the proposed approach a frontier is established considering the less critical failure modes. Considering this frontier, one can establish how much each failure mode must be improved to become relatively acceptable. A simplified case concerning an AFWS of a two loops PWR power plant is presented to shows the applicability of the proposed approach.

Revista árvore , 2003, DOI: 10.1590/S0100-67622003000100007
Abstract: four levels of shading (full sunlight (0%), 30, 50, 70% of solar radiation interception on growth, chlorophyll concentration and photosynthetic rate were studied in croton urucurana baill., a pioneer plant species. this species seedlings are of potential interest for reforestation projects and recovery of degraded areas. the seedlings were grown in pots containing soil and sand (2:1) and later transferred to plastic bags of 3 dm3 and submitted to different levels of shading (30, 50, 70%) of solar radiation and full sunlight, as control. the experimental design was completely randomized with five replicates and each experimental unit was composed of five plants. the results suggest that plants submitted to 70% shading showed higher dry weight accumulation in leaf and root, and higher plant height and leaf area. however, the seedlings root system showed higher dry biomass under full sunlight. it was observed a tendency to increase chlorophyll concentration and to decrease photosynthetic rate with the increase of the shading level.

Ciência Rural , 2005,
Abstract: Cupania vernalis Camb. é uma espécie arbórea pertencente à família sapindaceae, conhecida popularmente como camboatá, camboat . é uma espécie de grande importancia pelo seu uso em plantios mistos destinados à recupera o de áreas degradadas e preserva o permanente. Este estudo teve como objetivo básico caracterizar o desempenho ecofisiológico desta espécie sob condi es de viveiro. Avaliou-se o efeito de quatro níveis de irradiancia (Pleno sol, 30%, 50% e 70% de sombreamento) sobre as trocas gasosas, concentra o de nitrogênio, clorofilas foliares e crescimento de plantas jovens de Cupania vernalis. As plantas submetidas a 50% de sombreamento acumularam maior massa seca de folha, caule e massa seca total em compara o com as cultivadas a pleno sol, n o sendo observada diferen a quanto à massa seca de raízes. A maior taxa fotossintética e condutancia estomática foram observadas em folhas de plantas crescidas sob pleno sol e 30% de sombreamento. Plantas sob condi es mais sombreadas apresentaram teores mais elevados tanto de clorofilas quanto de nitrogênio nas folhas. Fato semelhante ocorreu com outras características como altura, diametro de caule e área foliar. Essas últimas características constituem fatores determinantes da qualidade de mudas. Os resultados possibilitaram concluir que as mudas desta espécie devem ser formadas sob condi es de viveiro com sombreamento de 50% ou 70% para que se obtenham mudas de melhor qualidade.
