The present study evaluates the performance of three numerical weather forecasting models: Global Forecast System (GFS), Brazilian Regional Atmospheric Modelling System (BRAMS) and ETA Regional Model (ETA), by means of the Mean Error (ME) and the Root Mean Square Error (RMSE), during the most rainy four months period (January to April 2012) on Eastern Amazonia. The models displayed errors of superestimation and underestimation with respect to the observed precipitation, mainly over center-north of Pará and all of Amapá, where the precipitation is higher. Among the analyzed models, GFS shows the best performance, except during January and March, when the model to underestimated precipitation, possibly due to the anomalously high values recorded.

Abstract: odontogenic myxoma (om) is an ectomesenchymal benign odontogenic tumor characterized by spindle or stellate-shaped cells embedded in an abundant myxoid or mucoid extracellular matrix. dna methylation is characterized by the addition of methyl groups in cytosines within cpg islands in the promoter gene. dna methylation can decrease the expression of tumor suppressor genes and contribute to the development of neoplastic lesions. the aim of study was to evaluate the methylation pattern of the tumor suppressor genes p16 (cdkn2a), p21 (cdkn1a), p27 (cdkn1b), p53 (tp53) and rb1 in om and dental pulp. methylation was evaluated using methylation-specific polymerase chain reaction (pcr). the transcription was studied in some cases by using reverse transcription quantitative pcr. a higher frequency of unmethylated p27, p53, and rb1 samples was observed in the om when compared with the dental pulp. om expressed mrna of all the genes evaluated. considering all the samples together, the expression of rb was higher in the unmethylated samples compared with the partially methylated samples. this investigation revealed hypomethylation of the genes p27, p53, and rb1 in om. in addition, methylation of tumor suppressor genes was found to be an usual event in normal dental pulp.

Pyoderma gangrenosum is a rare ulcerative cutaneous disorder commonly associated with systemic diseases such as inflammatory bowel diseases. This paper reports a case of pyoderma gangrenosum affecting the mouth and the skin associated with ulcerative colitis. A Medline search in English literature from 1961 to 2012 revealed only 11 documented cases of pyoderma gangrenosum with oral involvement. Previous reported cases of oral cavity involvement have shown that the most common sites of manifestation are the tongue, palate, and tonsillar fauces. This case emphasizes the importance of including inflammatory bowel diseases and their manifestations in the differential diagnosis of ulcerative lesions in the oral cavity.

Abstract: Small wastewater treatment plants (WWTP) are frequently located, by necessity, in remote and isolated sites, which increases the difficulty of its energy supply. Some of them are located near the seaside, in environmental sensible zones, and due to tourism activity of these sites, seasonal effects related with population size fluctuation can occur, which can originate certain inefficiencies concerning WWTP design and energy supply. The objective of this paper is to describe a step by step procedure for evaluation of the wind potential of sites that are dependent of in-situ energy generation, as well as, a case study on the utilization of the potential wind energy in Magoito WWTP (5000 p.e.). The employed methodology comprised the collection of one year of in-situ wind data and its validation by comparison with historical data of about 10 years of a nearby anemometric station. The data provided by the two anemometric stations was statistically treated. It allowed the analysis of the results from the two stations are promissory in terms of wind availability and velocity. Finally, it comprised the simulation of the local wind conditions for a considerable larger area in order to find the best site for locating a wind turbine.
