title: Endemic plants from the Southern Brazilian Highland Grasslands

description: Abstract The flora of the subtropical highland grasslands in Southern Brazil, locally known as Campos de Cima da Serra, is within the Atlantic Forest hotspot, and has being highlighted by its richness, having around 25% of endemic plants. Those formations require specific studies to estimate its species richness and to protect its natural resources. This study aimed to map and to analyze the distribution of endemic taxa from these grasslands based on available herbarium collections databases as sources for highlighting important taxonomic groups for future studies. We verified how much of those endemic taxa are inside protected areas, and recognized the most important taxa and areas for future studies. All the data about each endemic taxon was obtained through visiting herbaria, online databases, collecting expeditions and published references. Distribution maps for endemic species were prepared. As the main result, we describe and map the distribution of the endemic flora of this species rich vegetation formation and highlight the threatened taxa as priority for future taxonomic and conservation studies. Our results also point out the central-west of Santa Catarina and central Paraná states as priority areas for future studies considering its high diversity of taxa.

title: Comparative study of U diffusion in Zry-4 and pure α-Zr

description: ABSTRACT Throughout the α-spectrometry U diffusion in pure Zry-4 was studied and compared with pure α-Zr in the temperature range 843-1093 K in order to analyze the diffusion process in both matrices. D values are systematically higher in Zry-4 and its temperature dependence obeys the Arrhenius law being: D0 = (3,2 ± 1,1) m2/s and Q = (316 ± 9) kJ mol-1, whereas in α-Zr U diffusion present an apart to this law, consistent in a downward curvature in the ln(D) vs 1/T plot. Below 873 K U solubility in Zry4 is lower than in pure Zr.

title: A physiology-based approach to a patient with hyperkalemic renal tubular acidosis

description: ABSTRACT Hyperkalemic renal tubular acidosis is a non-anion gap metabolic acidosis that invariably indicates an abnormality in potassium, ammonium, and hydrogen ion secretion. In clinical practice, it is usually attributed to real or apparent hypoaldosteronism caused by diseases or drug toxicity. We describe a 54-year-old liver transplant patient that was admitted with flaccid muscle weakness associated with plasma potassium level of 9.25 mEq/L. Additional investigation revealed type 4 renal tubular acidosis and marked hypomagnesemia with high fractional excretion of magnesium. Relevant past medical history included a recent diagnosis of Paracoccidioidomycosis, a systemic fungal infection that is endemic in some parts of South America, and his outpatient medications contained trimethoprim-sulfamethoxazole, tacrolimus, and propranolol. In the present acid-base and electrolyte case study, we discuss a clinical approach for the diagnosis of hyperkalemic renal tubular acidosis and review the pathophysiology of this disorder.

title: Assessment of female sexual function in remote postpatum period: a cross-sectional study

description: Abstract Objectives: (i) to evaluate female sexual function in remote postpartum period within Brazilian women and (ii) to compare female sexual dysfunction in relation to the mode of delivery. Methods: in this cross-sectional study, two groups of remote postpartum women, who underwent vaginal delivery (n=30) and cesarean (n=48), were studied. The sexual function of participants was assessed through an online Brazilian version of FSFI between 45 and 180 days after delivery. Data were analyzed by descriptive and inferential statistics using Fisher exact test, and Student t test. Results: based on the data of 78 women who completed the online questionnaire, 78% (n=61) showed sexual dysfunction on remote postpartum period being that the FSFI mean score for vaginal postpartum was 22.17 and for cesarean postpartum, 21.12 (p=0.443). Conclusions: the majority of remote postpartum women showed sexual dysfunction. There was no significant difference found on female sexual function between modes of delivery.

title: Seasonal Climate Forecast to Brazil Obtained Through Global and Regional Climate Models

description: Abstract This study evaluates the ability of two global climate models (CPTEC and CFSv2) and a regional climate model (RegCM4) in predicting the seasonal climate in different regions of Brazil. RegCM4 was drove with the outputs of two global climate models: CFSv2 system and CPTEC. Two versions of RegCM were employed in the study: 4.3 and 4.5. RegCM4.3 was ran with six members of CFSv2 system, while RegCM4.5 was ran with a member of the CPTEC model. All forecasts started about two months before the season to be predicted and in all 94 simulations with the regional climate model were carried out. RegCM4 adds value to the predictions of the global climate models, mainly when it is nested to the CPTEC outputs. When RegCM4.5 is drove by CPTEC outputs and Emanuel cumulus convection parameterization is used, there is a good performance of the regional climate model in predicting the precipitation and air temperature in almost all Brazil.

title: Analyses of Shallow Convection over the Amazon Coastal Region Using Satellite Images, Data Observations and Modeling

description: Abstract The Belem region of the state of Para, which is located in northern of Brazil and part of the Amazon biome is characterized by high temperatures, strong convection, unstable air conditions and high humidity favoring the formation of convective clouds. Shallow convection and deep convection are among the main components of the local energy balance. Typically a deep convection over the continents is preceded by a shallow convection. An analysis of the performance of the Jet Propulsion Laboratory / National Aeronautics and Space Administration (JPL/NASA) model of shallow convection parameterization in a framework of the single column model (SCM), in relation to the cluster of cumulus clouds formed in the coastal region of the Amazon forest due to squall lines, is provided. To achieve this purpose enhanced satellite images and infrared images from channels 2 and 4 from the GOES-12 satellite, and data obtained by the “Cloud processes of tHe main precipitation systems in Brazil: A contribUtion to cloud resolVing modeling and to the GPM (GlobAl Precipitation Measurement)” - CHUVA - campaign, during the month of June of 2011, were used. During that period, clusters of cumulus clouds penetrated the interior of the Amazon, causing heavy rains. Results demonstrated that the parameterizations performed well in the case where only a core of clouds was observed, such as at 18:00h on 14 June. This period of the day also presents the smallest bias and root mean square error (rmse) values for the relative humidity. For the potential temperature the smallest value of bias is at 12:00h on June 7th (0.18 K), the largest one is on June 11th (-2.32 K) and the rmse ranges from 0.59 to 2.99 K.

title: Sclerosing hemangioma mandibular in Paralichthys orbignyanus: case report

description: ABSTRACT In this study, we described the first case of sclerosing haemangioma in an adult Brazilian flounder Paralichthys orbignyanus. Produced by artificial reproduction, the fish was approximately 10 years old and was maintained at a breeding stock. When removed from the tank, mandibular lesion with excoriations and hemorrhagic foci were noted. Tumor samples were collected from the mandible for histopathological analysis. Proliferation of numerous blood vessels surrounded by dense connective stroma was observed microscopically. The etiology of this neoplasia is unknown, but the fact that the specimen remained in captivity for many years, may have contributed to the appearance of this type of lesion, due to sporadic mechanical shocks to the tank wall.

title: Bioceramics of calcium phosphate nano-structured micro-macro porous granules rapidly absorbed in filling critical radial defect in rabbits (Oryctolagus cuniculus)

description: ABSTRACT The objective of this study was to evaluate the effect of HA/ βTCP on rapid absorption granules in rabbit radiography, histology, and bone densitometry. Thirty - five male rabbits of the New Zealand breed were used and a critical defect was performed on the right and left radios. The animals were distributed in GI, autologous graft and GII HA / βTCP in rapidly absorbed granules. Radiographic, histological, and densitometry evaluations were performed before surgery, then after eight, 15, 30, 45 and 60 days. A significant difference was found when comparing the bone mineral density obtained over the study time. Formation of vascular network between the bioceramic pores was observed by the first evaluation time, (eight days). Primary bone tissue and trabeculae were observed from preexisting bone tissue after 30 days of implantation. At 60 days, the presence of bone matrix was observed from the preexisting bone segments, characterizing the centripetal bone formation. The micro-macroporous nanocomposite HA / βTCP of rapidly absorbing granules do not cause microscopic changes indicative of rejection, allows invasion, cell multiplication, and promotes bone regeneration, constituting an appropriate implant for filling of critical bone failures.

title: The Relationship of the Incidence of Dengue Cases with the Precipitation in the Urban Area of Belém-PA, 2007 to 2011 Through Multivariate Models of Time Series

description: Abstract It was conducted a mapping study of the areas of incidence and predictions for dengue cases in the urban area of Belém, where the Dengue Incidence Rate (DIR) related to rainfall precipitation was used to forecast dengue occurrences using a multivariate model based on the Box and Jenkins time series methodology. The study period was 5 years (2007-2011). The results of the DIR data analysis and precipitation showed that the increase in DIR is accompanied by an increase in precipitation, demonstrating a direct relationship between these variables in the period under consideration, in the neighborhoods of the urban area of Belém, with greater emphasis in the neighborhoods of Marco, Guamá and Pedreira. The predictive model built for the DIR showed a good fit with satisfactory results and, in this case, can be used to predict dengue.

title: Semiotic Approaches in Mathematics Education

description: Abstract In this research, we analyze BOLEMA related to semiotics in the scope of researches in Mathematics Education. The question that guides our research is: What do the papers published in BOLEMA reveal about the semiotic approaches in Mathematics Education researches? So, our article brings to light the perspectives and issues that have been the focus of research about semiotics in Mathematics Education. We have identified three approaches in the research: the theory proposed by Charles S.Peirce; the theoretical constructs of Raymond Duval; and the ontosemiotic approach, whose mentor is Juan D. Godino. Our article presents elements that are considered relevant in each of these approaches, as well as the semiotic approaches of the 23 analyzed papers. Then, we present a summary that reveals the perspectives, issues, and understandings about semiotcs identified in the papers we analyzed and aim to establish some articulations between them. The article concludes with considerations about the contributions of semiotics in Mathematics Education.
