In the electrical distribution system, the insulating components may have their characteristics compromised by several reasons such as contamination, cracks caused by vandalism, nest of birds, among others. The influence that each type of variation can cause on its insulation capacity is difficult to determine and must be specifically studied. This article has as objective the evaluation through simulation of the electrical field distribution on the surface of insulators, considering the ambient ...

Many factors threaten the survival of marine turtles, such as incidental capture by fisheries, habitat degradation, pollution and diseases. One of the most important diseases is fibropapillomatosis (FP), characterized by the development of benign skin tumours. FP predominantly affects juvenile green sea turtles ( Chelonia mydas ) and involves a complex multifactorial aetiology. For several years, it has been noted that the prevalence of FP tends to be higher in marine environments under the influence ...

Oil exploration in marine fields located in deepwater and ultra-deepwater has been one of the challenges in oil production. To enable exploration in such conditions, huge investments have been made, and extensive research has been carried out in order to improve technology to the drilling fluids. In this way, the understanding and the monitoring of the properties of the drilling fluids are of vital importance to the exploration and production of oil in deepwater and ultra-deepwater conditions. The ...

Contamination of water resources through anthropic activities can alter water quality. The objective of this study was to monitor the presence and concentration of Escherichia coli in the water of Carmo Park - SP and evaluate the antibiotic resistance of E. coli isolated from water. Three collection points were analyzed and identified as: P1 – Stream with preserved riparian forest that supplies the main lagoon, P2 - Secondary lagoon without ciliary vegetation that also supplies the main lagoon and P3 - ...

Drawing on Actor-Network Theory and the cartography of controversies, we present a method for ANTi-History research to investigate the implementation of a contract between a labour services company and a public university hospital in Brazil. The research question focuses on how the past is enacted in the present. The method is a general guideline based on five focal points used to organize the fieldwork: identifying controversies; mapping the actor-network; drawing out the translation process; politics ...

RESUMO O presente estudo identifica as variáveis contextuais que melhor diferenciam o desempenho obtido por estudantes dos anos finais do ensino fundamental das escolas estaduais capixabas na Prova Brasil de 2013 por meio de análise discriminante, tendo como amostra 124 escolas. Os resultados demostraram que a distorção idade-série, o índice de regularidade docente e a taxa de abandono formaram um conjunto ótimo de variáveis para distinguir as escolas com “melhores” e “piores” desempenhos capixabas. ...

The PER3 gene is one of the clock genes, which function in the core mammalian molecular circadian system. A variable number of tandem repeats (VNTR) locus in the 18th exon of this gene has been strongly associated to circadian rhythm phenotypes and sleep organization in humans, but it has not been identified in other mammals except primates. To better understand the evolution and the placement of the PER3 VNTR in a phylogenetical context, the present study enlarges the investigation about the presence ...

Crypto-currencies, or crypto-assets, represent a new class of investment assets. The traditional portfolio analysis approach of Markowitz is not appropriate for use with portfolios containing crypto-assets, as the model requires that the investor have a quadratic utility function or that the returns be normally distributed, which isn't the case for crypto-assets. We develop a portfolio optimization model based on the Omega measure which is more comprehensive than the Markowitz model, and apply this ...

This paper studies the influence of debriefing in the learning of the participants of business games. Through quasi-experimental study we examined the self-declarations of 112 undergraduate Business Management students undertaking the 8th term, divided into two groups: experimental, exposed to debriefing; and control, not exposed to the debriefing. Mann-Whitney´s tests revealed that the quantum of learning perceived by the members of the experimental group was statistically significantly higher ...

In this work, a study on the modeling of sedimentation and transport of barite particles in drilling fluids was developed. The goal of this study was to evaluate the feasibility of using a simplified two-phase model based on conservation equations to describe the sedimentation of particulate material in drilling fluids. The model was evaluated in three different case studies, where the transport and the sedimentation of solid particles in a carrying fluid were simulated. The simulation results included ...

Oil-based muds (OBM) used in drilling processes are complex fluids formed by a water-in-oil emulsion stabilized by emulsifiers. Measurements of the electrical stability (ES) are considered directly indicators of mud stability, together with yield point (YP), and fluid loss (FL). In this work, it was studied the effect of oil-water ratio (OWR) in the mud stability using the ES, YP and FL data. To analyze those individuals and paired effects, it was applied a Central Composite Rotational Design (CCRD) planning ...
