title: Depositional, diagenetic and stratigraphic aspects of Macaé Group carbonates (Albian): example from an oilfield from Campos Basin

description: Carbonate rocks from the Macaé Group (Albian) represent an example of carbonate sedimentation related to the drift phase in Campos Basin. This study presents depositional features, integrating them with diagenetic and stratigraphic aspects of the Macaé Group carbonates including the upper part of the Quissamã Formation and the lower part of the Outeiro Formation. Macroscopic analyses in cores and microscopic ones in thin sections allowed the recognition of eleven sedimentary facies - nine of them corresponding to the Quissamã Formation and two of them representing the Outeiro Formation. These facies were grouped into five facies associations. Oolitic grainstones and oncolitic grainstones are interpreted to be deposited in shallow depth probably in shoals above the fair weather wave base. The interbanks between shoals were formed in less agitated waters and characterized by deposition of peloidal bioclastic packstones and wackestones representative of sedimentation in calm waters. Bioclastic packstones and oolitic packstones/wackestones represent allochthonous deposits related to the beginning of the regional drowning that occur in upper Quissamã Formation. Pithonellids wackestones and bioclastic wackestones with glauconite are related to deep water deposits, characteristics of the Outeiro Formation. Post-depositional features revealed the action of diagenetic processes as, micritization, cimentation, dissolution, compaction, dolomitization and recrystallization occurred during the eo- and mesodiagenesis phases. Vertical facies analysis suggests shallowing upward cycles stacked in a sequence progressively deeper towards the top (from the Quissamã Formation to the Outeiro Formation).

title: Customer Satisfaction based on the Attributes of Accommodation Services

description: Abstract The present research seeks to evaluate the contribution of attributes of lodging presented on TripAdvisor website - service, value, cleanliness, location, sleep quality, and room - to guest satisfaction in hotels and bed and breakfasts (B&B) located in Espírito Santo. The research follows a quantitative methodological approach, using secondary data automatically collected on the website. Data were analyzed using descriptive statistics and multiple linear regression. The results indicate that the attributes investigated contribute differently to customer satisfaction depending on the self-reported type of traveler (“Friends”, “Couple”, “Family”, “Business”, and “Solo”) and price category of the accommodation establishment.

title: Mais Educação Program in Latin America: legacies for deprived children and youth

description: Abstract: This paper aims to situate the emergence of Programa Mais Educação (PME - More Education Program) in the political and educational context of Latin America and analyze the social significance of this experience for deprived children and youth in Brazil. This discussion is carried out in light of the State Reform of the 1990s and social studies on childhood and youth. It identifies in PME evidence of both the neoliberal trend experienced by Latin America, marked by rupture, continuity and setbacks, and the legacies of this policy regarding the expansion of the right to education through a concept of integral education centered on children and youth, their cultures and territories.

title: Knowledge of medical students regarding living wills

description: Abstract The end of a person’s life raises many ethical dilemmas. Recently, the Brazil’s Federal Council of Medicine approved and regulated the concept of “living will”; as a result, it is of considerable importance that doctors understand the issues that surround this matter. The aim of the present study was to evaluate the knowledge of medical students from the Pará State University, Brazil, of “living wills” and decisions involving the end of life. A cross-sectional study was performed with 238 students who answered a questionnaire of 10 questions. Only 8% of students demonstrated a clear understanding of the term “living will”. Nevertheless, when the definition of “living will” was explained to the participants of the study by the researchers, 92% of students declared that they would respect its provisions. Therefore it appears that while most respondents had a low level of understanding of the concept of “living will”, the vast majority positioned themselves in favor of accepting such a document.

title: Sealing ability and penetration intratubular MTA Fillapex and AH Plus in human teeth

description: Abstract Introduction The MTA is an important use in dentistry material with good biological properties. The experimental responses to sealers using this compound in the sealing and filling of the root canal system, combined with a good instrumentation and cleaning, may be important in the periapical healing process. Objective To evaluate in vitro penetration depth of two different sealers in dentinal tubules and bacterial infiltration in fillings with AH Plus and MTA Fillapex cements. Material and method 34 premolars human monorradiculados were selected, their removed and their standardized root crowns in 16mm, after then randomly divided into two groups of 15 specimens, and instrumented with rotary system Pro Taper. One group was obturated with cement AH Plus (group HA) and another MTA Fillapex (FI Group). These groups are evaluated for coronary infiltration of bacteria Enterococcus faecalis and the depth of penetration in the dentinal tubules. For the measurement of bacterial infiltration used Fisher's exact test for Intratubular penetration we used the t-test. Result For bacterial infiltration, considering the number of infiltrated samples AH and MTA Fillapex, there was a statistically significant difference (p = 0.0341). In the evaluation of intratubular penetration, the difference between the two groups of cement was statistically significant (p = 0.0006). Conclusion Both cements showed bacterial infiltration and the MTA Fillapex had worse performance, capabilities to enter the dentinal tubules AH Plus was significantly higher than the MTA Fillapex.

title: The dentin thickness remaining in the risk zone of mandibular molars after cervical preflaring with four methods

description: Abstract Introduction Cervical preflaring is an important step of the canal system instrumentation, but can lead to excessive enlargement or root perforation. Objective Evaluate the remaining dentin thickness in the mandibular molars of mesial roots using cone beam computed tomography: Gates-Glidden (crown-down); Gates-Glidden (step-back); LA Axxess and Easy Pro-Design. Material and method Were selected 40 lower molars mesial roots, which were scanned in a cone beam CT scanner before and after preparation. Were obtained five sections of the CT images with an interval of 1 mm from the furcation, and measured the thickness variation between the root canal to the root external portion in analysis software. Result The evaluation of the different levels showed no significance within the same group for the Gates-Glidden group. On the other hand, were observed difference for LA Axxess (p=0.002) and Easy Pro-Design (p=0.005). In the intergroup analysis, were observed difference in all levels, especially for Gates-Glidden in the ascendant order (ANOVA and Tukey). Conclusion Within the limitations of these study, is possible to conclude that the protocol with greater wear in the cervical risk area was the Gates-Glidden in step-back sequence, as the other groups were equivalent (p&gt;0.05).

title: Reliability analysis of welded and bolted connections in cold-formed steel sections

description: Abstract This article shows a study of the level of reliability of welded and bolted connections in cold formed steel members, for some limiting states, adopted by AISI and Brazilian codes. The aim of this study is the assessment of the reliability index β for a variation of the nominal live-to-dead load ratios as well as comparison of the value found considering different load combinations. The first order reliability method is used to calculate the reliability index β. In this study, reliability indices smaller than 3.5 were obtained, especially for bolted connections. Consideration of the model errors and FORM method, lead to significant reductions in reliability indices, which are found to be less than the recommended target reliability levels.

title: The Quest for land at Piranema sand cluster

description: Abstract The Piranema Sand Cluster, located between the Seropédica and Itaguaí counties of Rio de Janeiro Metropolitan Region, is responsible for 65% of the sand used in construction works of the region and is the home of approximately 47 small mining companies. The construction works in progress in this area make this mining district a critical success factor for these new or expanding ventures, for prices of construction sand increases tremendously with delivery distance. These undergoing works attract many people to the region, increasing the need for urban infrastructure to house them. This search for land comes from mining sites and causes difficulties in obtaining local permits, which are the first step in environmental compliance of the mining activities. The discussion of this paradox: “cheap aggregates for urban infrastructure and the displacement of mining to make room for the installation of these infrastructures”, must be based on a Future Use Project for this area, seeking consensus among communities, mining, government and other stakeholders. This enables the preparation of a Decommissioning Plan for the mines that reconciles the mineral reserves yet to be exploited to the needs of other land uses that development is promoting. By doing this, a regional planning proposition is established in order to recover the degraded area and ecosystems, ensure the well-being of the population, improve employment generation and income of the affected people, and keep the prices of construction sand at low levels, while showing great respect to the environment.
