title: Relationship among local and functional factors in the development of denture stomatitis in denture wearers in northern Brazil

description: OBJECTIVE: The aim of this study was to evaluate the relationship among functional and qualitative factors in the development of denture stomatitis (DS) (according to Newton's classification) in acrylic-based denture wearers residents from northern Brazil.MATERIAL AND METHOD: A total of 99 patients who wore partial or total acrylic resin-based upper dentures were included in this study. The subjects completed an epidemiological data form that includes the patient's gender, age, local factors (hygiene habits, remove denture to sleep, use of mouthwash, present condition of the denture, age of the denture) and functional factors (vertical dimension at rest, vertical dimension of occlusion, occlusion, retention, and static and dynamic stability). To detect yeasts, samples were collected from the inner surface of the dentures and from the palatal mucosa in contact with it. Subsequently, the samples were cultured on Sabouraud dextrose agar, observing macro and microscopic characteristics.RESULT: In the present study, we did not find any significant relationship between the gender and disease onset. Based on the Newton classification, 36.3% of the patients presented with DS and 89.0% were colonized by yeasts; of these subjects, 50% had type I lesions, 33.3% had type II lesions, and 16.6% had type III lesions. All of the qualitative and local factors, except the use of mouthwash, were clinically relevant to the development of disease.CONCLUSION: Denture stomatitis in denture users in northern Brazil was multifactorial, involving local, functional and microbiological factors.

title: Land-use change effect on the hydro-dynamic characteristics of soil in the Brazilian semi-arid region

description: Abstract The search for better living conditions has led the residents of the Brazilian semi-arid region to plant forage crops, leading to a gradual decrease in the native vegetation (Caatinga) of this region. The effects caused by the replacement of Caatinga with palm, for example, have been little studied, especially with regard to the physical and hydraulic properties of the soil. The objective of this study was to compare the physical-hydraulic characteristics of a litholic neosol in two areas having different vegetation cover: one area cultivated with forage palm (O. ficus-indica) and the other covered by native Caatinga. Differences in soil structure, especially in porosity, between the natural and cultivated soils were observed to control the hydrodynamic processes, resulting in changes in water retention curves and hydraulic conductivity. Natural soil presents low values of hydraulic conductivity when compared to those of cultivated soil. This increase is probably due to soil management required for forage palm cultivation. The natural soil structure, characterized by relatively low saturated hydraulic conductivity values, presents an infiltrability that favors surface runoff. Human activities in the study area have promoted changes in the soil’s physical attributes, decreasing density and increasing porosity. Consequently, there is an increase in water infiltration into the soil and a reduction of runoff in cultivated areas, confirming results obtained in previous studies.

title: Fe-Cu skarns deposits in the Santa Quiteria magmatic arc, Borborema Province, Brazil

description: Abstract W-Mo skarns deposits in the Borborema Province have been known since the 40's, however, until this study there were no records of Fe-Cu skarns. In Ceará State, Brazil, the first occurrences of Fe-Cu skarns were identified recently in the Magmatic Arc of Santa Quiteria, product of superposition of several magmatic arcs, ranging from juvenile arc (870 - 800 Ma), up to continental collision (625 - 600 Ma). The skarns are associated with calc-silicate rocks and dolomitic and/or calcitic marbles, cut by Neoproterozoic, early to tardi-collisional quartz monzonite. In the area several skarn system types are found such as endoskarns, hornfels, skarnoids and exoskarns. The exoskarns show two mineral assemblages, reflecting different carbonate protolith: the first consists of clinopyroxene-garnet (prograde stage) and magnetite-pyrrhotite-chalcopyrite-pyrite-biotite (retrograde stage), characteristic of calcitic protolith, and the second, consists of olivine-spinel-diopside in prograde phase and serpentine in retrograde phase, representative of dolomitic protolith. Garnets partly zoned exhibit composition dominated by andradite (82 - 52 mol%) with subordinate grossularite (16 - 45 mol%) and minor pyrope (2 - 3 mol%). The pyroxene of the marble calcitic protolith is typical of the diopside-hedenbergite series, with average composition Diopside46Hedenbergite52Johannsenite2. Three types of iron-dominated skarn related ores are distinguished: i) banded magnetite; ii) disseminated magnetite; iii) vein massive magnetite. Takes place also a sulphide copper ore with and without associated magnetite and gossans blocks. The geological and metallogenic data obtained indicate that the genesis of these skarns are associated with the influence of monzonitic Brasilian granites and although there are two types of skarn, there is a predominance of Fe-Cu Skarn.

title: Determinants of young people’s participation and income in the labor market: the case of the Metropolitan Area of Recife

description: Abstract This article analyzes the determinants of the entrance of young people from the Metropolitan Area of Recife in the labor market, as well as the determinants of the income received by those who work. An equation was estimated using the procedure proposed by Heckman for sample selectivity, using data from PNAD (2012). The results show that being male and the head of the family, being a major, and having a higher level of schooling positively affect the young adult’s decision to enter the labor market. As for the determination of income, being male, white and having a higher level of schooling make the income be higher. Therefore, investing in young people’s education and in their access to it is an indispensable step towards reducing social disparities in the Metropolitan Area of Recife.

title: The social construction of a smart mobility system: mapping controversies in the case of SwissPass

description: Abstract The prevalent idea of smart cities presupposes the use of digital technologies for an alleged more efficient management of urban dynamics and systems. There is a scientific need to know more about such processes in the social sciences. Among the various sectors of urban management, mobility is one of the most sensitive to technological changes. The aim of this article is to historically deconstruct the SwissPass project and to understand its sociotechnical nuances through the identification of social groups and interests, as well as through the mapping of controversies involved in the implementation of this smart mobility system in Switzerland. The results indicate power disputes, dominance of the process by large, state-run transport companies, and dissipation of the controversies by persuasion strategies focusing on its alleged innovative role.

title: International migration of women and paid domestic work: oppression and citizenship in the era of globalization

description: Abstract This work has as its objective the elucidation of some of the conditionings evolved in international migration of women and the performance of paid domestic work at the country of destination. Migrant women suffer innumerous oppressions along their trajectory, and our goal was not to list them, but to identify some and emphasize there is a structure of inequality in which this exploitation happens, legitimized too by the narrow personal scope given to the concept of citizenship, especially in international treaties.

title: Dental care for children with Congenital Zika Syndrome

description: ABSTRACT There was a large increase in the number of newborns with microcephaly in Brazil between 2015 and 2017, mainly in the Northeast. This increase was associated with intrauterine Zika virus infection, which causes a congenital syndrome characterized by neurological, musculoskeletal, and sensory abnormalities. Despite the great worldwide repercussion, few studies about oral conditions in children with the syndrome have been published. This work aims to propose a guide for the dental care of these individuals on the basis of a literature review. Children with congenital Zika syndrome have a number of systemic comorbidities that affect their oral health and can compromise dental care. To date, no clinical protocol has been established for the dental care of children with congenital Zika syndrome. This is a pioneering study of great importance to orient dental professionals and promote the dental health of these children.

title: Interfaces, gaps and challenges between bioethics and oncology

description: Abstract Bioethics and oncology are interdisciplinary areas that aim at the integral understanding of the human being. This article made a survey of studies on interface between these areas, identifying possible contributions, gaps and emerging challenges. We carried out an integrative review that sought the descriptors “oncology” or “cancer”; “bioethics” or “ethics”, and found 29 articles. The discussions referred to the knowledge or application of principles of bioethics in oncology; difficulties in the physician-patient communication; and ethical standards in research. Therefore, it is necessary to guarantee the application of bioethics’ principles; to increase investment in the formal teaching of bioethics, to improve interpersonal and physician-patient communication skills; and to disseminate bioethics to the general population. It is hoped that this study will give continuity of those already carried out, and that new interests will arise on the subject.

title: Oroantral fistulas closure using Bichat's fat pad

description: The oroantral fistula is one of the complications most common after dental extractions in posterior maxillary, mainly in the region of second and third molar. The diagnosis is based on clinical signs and symptoms, which may be present in pain, fever, hyposmia and drainage of purulent discharge; additional examinations such as computed tomography and sinus nasal endoscopy improve diagnostic precision. It is therefore of paramount importance to correct early diagnosis and treatment avoiding in this way, the symptons of sinusitis, infections and dysphonia. Several surgical techniques have been proposed for the closure of the bucosinusal fistula; the use of Bichat´s fat pad has become a successful alternative among them. Many surgical treatments have been to propose for closure of bucosinusal fistula; Bichat fat pad has been a good alternative. The propose for this article is report two cases with closure of bucosinusal fistulas through Bichat's fat pad, as well as to discuss the surgical techniques, characteristics, indications and peculiarities.

title: Evaluation of zinc removal and compressive strength of self-reducing pellets composed of Electric Arc Furnace Dust

description: Abstract The amount of Electric Arc Furnace Dust (EAFD) is continuously increasing in mini-mill steel plants. This dust is considered a hazardous waste because of the presence of elements like lead, cadmium and chromium. Among many different treatment processes for this issue, there is the possibility of returning the EAFD back to the Electric Arc Furnace. This article presents a study of the compressive strength of self-reducing cold bonded pellets as well as their zinc removal, in an agglomerate containing EAFD, petroleum coke (PET) and Portland cement. The effects of the reductant and binder employed were discussed. Moreover, an apparatus was built to prevent zinc gas reoxidation inside an electric vertical laboratory furnace. Thus, the fraction of weight loss complemented the result of a previous study indicating the optimal content of PET source usage between 10 to 15%, in mass. Zinc removal and additional X Ray Diffraction outcomes are shown and discussed, concluding that 80% of zinc removal for this system could indicate the possibility of the EAFD reuse.

title: Using an operating microscope to re-treat an inferior premolar with two canals

description: This report aims to present a clinical case of endodontic re-treatment performed on a left inferior premolar with two canals of difficult localization. The importance of anatomical knowledge and the use of an operating microscope, especially in complex reintervention are discussed. An endodontic re-treatment was performed on element 34, which had a prosthetic restoration and vestibular fistula. In clinical examination, it was observed a negative result to the sensitization test and a positive result to vertical percussion test. After all the obturating material was removed, an operating microscope was requested to assess a possible fracture or the presence of another canal. It was noticed the presence of another canal that was treated and obturated as the existing canal. After 12 months, a new radiographic exam was performed, whose result was found asymptomatic and radiographically normal. In complex peculiar anatomy cases, the operating microscope is vital for the localization of extra canal to guarantee treatment success.
