Kaio da Silva Pimentel Figueiredo, Gabriel Machado Stutz Xavier, Dayane de Souza Pereira, Jennifer Santos Rosa, Tainá de Mello Ribeiro, Hans Schmidt Santos, Felipe Barbosa Venancio de Freitas, Rogério Manhaes Soares, Rayssa Barcellos Paiva
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105362
Abstract:
This work presents the analysis of magnetometric data of an aerial survey conducted in the Rio do Peixe Sedimentary Basin, which is a promising oil producing region in the state of Paraíba, Brazil. The collected aeromagne-tometric data allowed the preparation of maps regarding magnetic anomaly, horizontal and vertical derivatives, analytical signal and Euler Decon-volution that were compared with the geology, topography, and regional seismic. Thus, we identified the main lineaments of the basin that were Tatajuba, Portalegre, and Malta faults. Furthermore, we also found a maxi-mum basin depth of almost 1400 m, which is compatible with the available seismic survey.
AVO Didactic Analysis from Simplified Modeling of Seismic Data in Libra Oil Field of the Pre-Salt Region, Brazil  [PDF]
Kaio da Silva Pimentel Figueiredo, Kaendra Williams Temoteo, Rafael Ximenes Goncalves, Yasmim Monteiro Cordeiro, Rogério Manhaes Soares, Hans Schmidt Santos, Claudiomar Rodrigues Franco, Felipe Barbosa Venancio de Freitas, Christyne Barros de Sá
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105788
Abstract:
In this study, a certain zone of Libra oil field of the pre-salt region was se-lected to be analyzed for didactic purposes in order to simulate AVO re-sponses. The region was modeled using seismic data, setting up a typical oil system with source rock (shale), reservoir rock (sandstone), and seal rock (salt). Thus, a set of parameters such as seismic wave velocity, density and Poisson’s ratio for the studied zone was proposed. The AVO analysis allowed the classification of reflectors and the distinction of the geology for sandstones saturated with both water and gas.

Abstract: This article presents ananalyses based on an empirical studywhich aims to discuss the process ofsecularization of marital relationshipsin the Rio Grande do Sul, during theperiod comprised between 1766 and1890. A special focus is placed on theanalyses/examination of some processof divorce proposed by women fromthe countryside of Rio Grande do Sul.It enables to understand somequestions related to the formation,constitution and development of the“gaúcha’s” society, especially when itexamines small localities-structured astraditional rural society. Finally, it showsthe evolution of the maritalrelationships in the Rio Grande do Sul,based on an first moment in thepatrimonial alliances to the system ofunions established through the prismof sexuality, also present in thenowadays society.
Structure of the tree component in an area of riparian forest in the Piratini River Basin, Rio Grande do Sul, Brazil

Biotemas , 2009,
Abstract: The vegetation studied belongs to the Pampa biome. The vegetation of this region is described as Open Arboreal Savanna because it presents a herb stratum and an arboreal stratum with a gallery forest. This study aims to describe the structure of the forest trees of the Basin (31o35’33”S and 53o02’39”W) contributing to knowledge of forest formation in the southern half of Rio Grande do Sul. All living or standing dead individuals in an area of 0.5ha with DBH ≥ 5cm were sampled. Each individual was recorded for its species, diameter at breast height – DBH, and estimated height. Of the 702 living individuals inventoried, 41 species belonging to 25 families were recorded the Myrtaceae family presented the greatest richness with seven species, followed by Salicaceae with four and Lauraceae with tree species. Anarcadiaceae, Asteraceae, Euphorbiaceae and Sapindaceae each showed two species. The other families sampled consisted of a single species only. About 53 individuals were counted dead, corresponding to 7.5% in relation to the quantity of living individuals. The highest importance value was attributed to Lithraea Brasliensis March. The Shannon diversity was estimated to be 2.99 nats (J’=0.81), one of the highest values registered below the 30o south parallel.

World Journal of Cardiovascular Diseases (WJCD) , 2012, DOI: 10.4236/wjcd.2012.24041
Abstract: Purpose: To investigate the prognostic impacts of a combined clopidogrel-metabolizing genotypes CYP 2C19 (+ or -)*2/(+ or -)*17 on patients with acute coronary syndrome (ACS). Population and methods: Prospective, longitudinal study of 95 patients admitted for ACS to a single coronary care unit. Patients less than 75 years of age, who survived hospitalization and to whom clopidogrel was prescribed, were included. CYP2C19 genotyping was performed at dis- charge. For analysis, the patients were grouped as follows: Group A ([+]*2/[+]*17) n = 8; Group B ([+]*2/[-]*17) n = 18; Group C ([-]*2/[+]*17) n = 27; and Group D ([-]*2/[-]*17) n = 42. Platelet function was assessed by an ADP platelet aggregation test using a commercially available kit. The primary end-point was a composite of mortality or readmission for ACS. The median time of follow-up was 136.0 (79.0 - 188.0) days. Results: The mean age of the study patients was 59.9 ± 10.7 years, and 83.2% were male. The allele frequencies of CYP2C19*2 and CYP2C19 *17 were 14.2% and 20%, respectively. Both allele frequencies were in Hardy Weinberg equilibrium. The patient groups were homogenous for demographic data, cardiovascular risk factors, GRACE and CRUSADE bleeding scores, left ventricular ejection fraction, and coronary anatomy. ADP platelet aggre-gation was similar for all groups (respective rates for groups A, B, C, D were 17.5 U (10.3 – 18.7) vs 20.0 U (17.3 – 26.8) vs 16 U (12 – 19) vs 12 U (8 – 22), p = 0.4). Event-free survival was significantly lower for group B (respective rates for Groups A, B, C, D were 87.5% vs 68.8% vs 96.3% vs 92.5%; p = 0.02). By multivariate Cox regression analysis, the CYP2C19 (+)*2/(-)*17 diplotype was an independent predictor of outcome, conferring a 5.2-fold higher adjusted risk for the composite endpoint than the others diplotypes. Conclusion: In our study, patients with the intermediate plus non-ultrarapid clopidogrel-metabolizing genotype ([+]*2/[-]*17) had a significantly poor medium-term prognosis for ischemic events, compared with the other diplotypes.

Recognizing the level of complexity that the subject involves, aspects related to interpretations and dominant ideologies in development/growth concepts are shown initially. The second part of this work constitutes a critical analysis of forty-three of the most well-known national and international indicators used to measure thisphenomenon. It is imagined that this analysis can show the state of the art for constructing development indicators. The development process covers a complexity of relationships. Its analysis, therefore, cannot be restricted only to the economic dimension because, as a rule, the question is presented both in the media and aconsiderable part of specialized literature. Emphasis on this dimension has historic origins, which have already shown the fragility of this approach.

Abstract:

The umbucajazeira is specie native to the Brazilian Northeast semiarid areas, which is economically explored based on the fruit. The fruit has a high agroindustrial potential, mainly for jam production. The aim of this study was to evaluate through sensorial analysis, two formulations of umbu-caja jams: a dietetic one with xylitol, used as an option for substitution of the sugars, and a conventional one. The proportion of 50:50:0.5 (pulp/sugar/pectin or pulp/xylitol/pectin) was used for jam processing. The mixture was concentrated up to reach 65°Brix. The jams were evaluated by 50 non-trained tasters, through a hedonic scale of nine points, whereas the following attributes were used: appearance, color, flavor, aroma and texture. The results of the physical and physicochemical analysis showed that the characteristics of jams prepared with sucrose are close to the ones made with xylitol, except for the total sugars and the energetic value. The jams had pH values ranging between 2.37 and 2.92; titratable acidity varying between 0.56 and 0.78 g citric acid/100 g pulp; soluble solids ranging between 60.92°and 65.08°Brix, respectively. A tendency for yellow color was noticed by the color analysis. Jam diet had the highest scores for appearance (7.4 - 7.7). No significant differences (p > 0.05) were obtained to flavor and texture. The fruit of the umbucajazeira showed to be adequate for jam manufature since they had good sensorial acceptance. The use of xylitol was satisfactory for obtaining a product with jam characteristics similar to the conventional jam, but with lower energetic value.
