In this article we present a didactic sequence that was developed for teaching of concepts of Thermology based on theoretical assumptions of historical-critical pedagogy (HCP). This pedagogy understands man as a historical being, built over time, and education as a fundamental process for this humanization. The didactic sequence, which has the theme “Global warming”, was structured based on the five structuring...
O presente artigo traz um recorte de uma dissertação de mestrado, que teve como objetivo investigar como os egressos do curso de Licenciatura em Matemática do Instituto Federal de Alagoas (IFAL) se posicionam frente à formação para ensinar geometria. Como fundamentação teórica, utilizaram-se os estudos de Tardif (2002-2014), García (1999) e Imbernón (2011) no que concerne à formação de professores e saberes ess...
A adsorção nos últimos tempos passou a ser utilizada como uma operação unitária importante, apresentando-se como uma alternativa importante e economicamente viável no tratamento de efluentes. Diante do exposto, o objetivo principal deste trabalho é estudar o potencial da utilização de zeólita NH4-Y como adsorvente de bário proveniente da água produzida. Os resultados obtidos evidenciaram que a água produzida do...
The objective this study was to characterize and develop anthropomorphic liver phantoms in tomography hepatic procedures for quality control and improvement professionals in nuclear medicine. For the conformation of the anthropomorphic phantom was used in plaster and acrylic. We constructed three phantoms representing processes with liver cirrhosis. The phantoms were filled with 99mTc diluted with water to obta...
Objectives: To analyse the prevalence of hip and lower limb fracture in the city of Aracaju (Sergipe) using data from the Fundação de Beneficência Hospital de Cirurgia from June 2008/2009 and comparing with results from studies of same nature developed by Komatsu (2004) in 1994/1995 in the city of Marilia (São Paulo) and Muniz et al (2007) in 2003/2005 in Paraná. Methods: Fracture types, age and gender were ana...
MOSFET electronic devices have been used for dosimetry in radiology and radiotherapy. Several communications show that due to the radiation exposure defects appear on the semiconductor crystal lattice. Actually, the structure of a MOSFET consists of three materials: a semiconductor, a metal and an insulator between them. The MOSFET is a quadripolar device with a common terminal: gate-source is the input; drain-...
