This paper presents a study of optimization of operational recovery credit default with geoprocessing use through geoprocessing tools, developed in the Receivables Management Companhia de Eletricidade do Estado da Bahia-COELBA sector. The work was initially based on the application of Data Mining Tools for Software KNIME 2.9 and later use of the tool of GIS-ArcGIS 10.X/ESRI .Were evaluated and applied analytical processing algorithms, to improve the process of spatial selection and define the best sets logistical credit recovery： The focus study, based on geoprocessing use in cutting action is due to the fact that this process has the largest collection efficiency. It is understood that the efficiency of the cutting action, should the great importance that electricity has on modem life. The research was guided its evolution from analysis of algorithms agglutination and georeferenced database, whose focus was and is acting in the cutting action due to the fact that this process has the largest collection efficiency. For the implementation of the study, through some geoprocessing techniques, the Mpar-cluster, this optimization model was developed from a custom algorithm for spatial selection, that had with subsidy： information stored in geographic databases, database information alphanumeric, images （aerial photographs and satellite images）, text files, and digital tables.

Selenium (Se) is an essential element to human. However, this element can be in low content in soil of some regions. Se deficiency may cause Keshan disease, thyroid dysfunction and osteoarthritis. The Se-enriched cereals are an interesting way to prevent these diseases. But, recent studies have shown that Se-enriched mushrooms are a better Se source. This occurs due to the high capacity of the fungi to absorb and transform the inorganic Se to organic forms, which are more bioavailable. Pleurotus ostreatus and Pleurotus eryngii are mushrooms species worldwide consumed and able to Se bioaccumulate. However, depending on the level of this element, it can be toxic for the fungus. Here we showed that the presence of the Se in culture medium decreases fungal growth rate, hyphae diameter and septum distance and causes alteration in color of colony. A garlic strong smell was directly proportional to Se level. P. eryngii was more tolerant to Se than P. ostreatus. So, it is important to screen this element level for Se-enriched mushroom production.

Research has shown that dissatisfied couples in the relationship commonly exhibit facial expressions of contempt in interactions. At this point, based on the study of cognition and physiology, researchers were able to predict by longitudinal studies the probability of divorce in a marriage, with accuracy of up to 94%. Our objective was to investigate whether the occurrence of facial expressions of disgust and contempt in married women is associated with marital dissatisfaction. This is an experimental study that correlated, through filmed interviews, the frequency of facial expressions of disgust and disgust (Facial Action Coding System) to the Marital State’s Golombok Rust Inventory, in a sample composed of 20 women. Data analysis based on the Spearman Correlation Test showed a positive correlation between facial expressions of disgust and disdain and conjugal dissatisfaction (rs = 0.2198, p = 0.0280), corroborating the data in the literature.
