Objectives: This paper describes a technique to produce individualized X-ray positioning devices for intraoral digital imaging of dental implants with long-term stability. Materials and Methods: An X-ray positioning device was built for Gendex? Visualix? eHD sensor, using the Dentsply rinn XCP-DS? system individualized by the incorporation of the bite piece within an acrylic stent to perform successive standardized radiographs to 16 patients. X-ray tube stabilization was achieved with polivinylsiloxane. Series of 3 radiographs were taken to each patient in different moments. Specific linear measurements as the implant diameter (mesio-distal width) and the height between consecutive threads (thread pitch) were made to all radiographs to determine the reproducibility and accuracy of the procedure. Results: The intraclass correlation coefficient for the mesio-distal width was 0.964 [(0.920 - 0.986) 95% CI] (p 0.00156 mm for the test value of 3.3 (p = 0.9), -0.00026 mm for 0.8 (p = 0.96) and 0.0124 for 4.125 (p = 0.72), respectively, after the application of a magnification correction factor. Conclusion: The device produced reproducible images in different moments and was suitable for comparative clinical examinations of marginal bone as it was convenient to perform reliable linear measurements.

Obesity is a difficult disease to control;bariatric surgery is one of the tools used to treat obesity and its comorbidities. The present case was chosen because it concerns a very obese patient whose proposed surgery—duodenal switch—resulted in traoperatively difficult to the medical team because the esophagogastric junction could not be reached due to the presence of hepatomegaly. Due to this unfavorable condition, we decided to perform a duodeno-ileal anastomosis with gastric preservation and without duodenal exclusion. The patient has been under follow-up for 14 years. She has lost 55 kg and maintains the comorbidities controlled to date.

Chromate and dichromate sodium as a function of oxidizer characteristics are used in several industrial areas; for example, in surface protection of coated parts of cadmium, zinc and aluminum （chromate coated treated）, corrosion inhibitors, the treatment of leather, the manufacture of pigments, etc. However, the use of such products has been questioned due to the problems of toxicity and pollution that can be caused in the environmental. The Brazilian environmental agency has established that the concentrations of chromate in water courses are less than 0.5 ppm. In order to reuse chromate （CrO42） from industrial effluent, laboratory experiments have been proposed based on chemical reduction or electrolytic processes, in order to transform these chromate ions in a final mix of oxides （in solid form）, which can then be packed and sent to the production process of sodium chromate. The results of these experiments have become useful industrially （without regard to costs） considering the environmental reuse and the life cycle of the chemical compound.

Amazonian Dark Earth(ADE) is a highly fertile soil of anthropogenic origin characterized by high levels of charred black carbon(BC). It is considered a model of fertility; however, knowledge on the fungal community structure and diversity inhabiting ADE and its BC particles is scarce. Fungal community structure and diversity of ADE and its BC from four sites under different land uses(three agricultural systems and a secondary pristine forest) in the Brazilian Central Amazon were evaluated by 18S rRNA gene pyrosequencing. Fungal communities in ADE and BC were dissimilar and showed differential abundances of fungal operational taxonomic units(OTUs). Estimated fungal species richness(abundance-based coverage estimate and Chao-1 index) and diversity estimators(Shannon and Simpson's reciprocal indices) were higher in ADE than in BC in all agricultural areas. No differences were observed in those parameters in ADE and BC samples from the secondary forest. Pezizomycotina fungi and OTUs assigned to Cordyceps confragosa,Acremonium vitellinum, Camarops microspora, and Hirsutella rhossiliensis were more abundant in BC particles than in ADE. These findings represent a breakthrough in our understanding of fungal communities in BC particles from ADE, and will be valuable in future studies considering biochar application in soil.

The burning of fuel oil with high sulfur content in diverse industrial segments results in the generation of oxidized sulfur compounds (SOx). These emissions, directly or indirectly, lead to the deterioration of air quality with consequences including the development of lung diseases in the surrounding population, the generation of acid rain and damage to civil constructions, such as public buildings, public squares, historic monuments, bridges, etc. This article describes the mechanisms of corrosion that occur in reinforced concrete deterioration observed in an industrial plant by the action of direct emissions of sulfur dioxide. SO2 in this case study is from the burning of fuel oil high sulfur content from chimney of an industrial boiler. The deterioration of concrete was evaluated in the laboratory showing the formation of calcium sulfate and calcium sulfate hydrate associated with aluminum oxide (Al2O3) and calcium oxide (CaO).

Obesity has been growing in Brazil and in the world. It is reaching epidemic proportions, and bariatric surgery is the most effective treatment for patients with this disease. Among the procedures described in the literature, ileal surgeries such as biliopancreatic diversion with duodenal switch (BPD-DS) and single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) present better long-term results in terms of weight loss and comorbidities control. However, there are concerns regarding long term nutritional problems with these procedures. In this case report the aim is to demonstrate the technical feasibility of preserving an extended duodenal bulb segment, in the SADIS-S procedure, when there are difficulties in dissecting the retrobulbar region, as occurred here, due to fibrosis in this area. This assures the maintenance of the proposed surgical technique, in such a situation. The dissection and transection of the duodenum was done 7 cm distally to the pylorus, under endoscopic view, proximally to the papillae, where the tissue was normal. Additionally, due the importance of the duodenal mucosa on minerals and trace elements absorption and the release of important hormones in this region, this case report elicits the evaluation of the impact of this technical modification, which occurred casually, in the nutritional, hormonal and metabolic results, long term. In this case report, the extended duodenal length has demonstrated reasonable weight loss, adequate comorbidities control and good nutritional status, so far. These aspects must be evaluated in the long term, by clinical trials.
