Os linfomas de baixo grau plasmocitóides caracterizam-se por adenopatias periféricas, comprometimento do baço e invasão medular nos diversos estádios da doença. Os autores apresentam o caso clinico de um doente com 63 anos de idade, antecedentes pessoais de vitiligo, admitido por anorexia, astenia e perda ponderal de 30Kgs, associado a bicitopénia grave (Hb 6.4mg/dL, normocítica, normocrómica, e leucopenia de ...
O estudo aqui apresentado procurou identificar as abordagens à aprendizagem em estudantes da Universidade de Évora em função das suas características, nomeadamente, género, ano e escola em que se insere o curso que frequentam, gosto pelo curso, perceção de dificuldade do curso e autoavaliação enquanto alunos. Recorremos ao ASSISTsv (Approaches and Study Skills Inventory for Students – short version). A amostra ...
Two series of silicate glasses were processed to micron-size, sub-micron size, and nanoparticles using three different milling systems: ball milling, attrition, and high-energy milling. The effect of milling time and media size on particle size and contamination were investigated in aqueous and isopropanol suspensions. The particle size was determined using a laser-diffraction particle size analyzer and scannin...
Current and future research goals in our laboratories include the study of the attack of glass-contact refractories and of crown refractories in glass tank melters, under either air-gas or oxyfuel conditions. There is an emphasis on evaluation and characterization of critical parameters of commercial refractories such as microstructure, porosity and mechanical properties. A second focus is the evaluation of the...
The degradation of refractories used in the construction of glass melting furnaces, whether caused by the action of molten glass, vaporized melt constituents, products of fuel combustion, or by batch dusts and vapors, can normally only be assessed after a campaign when the furnace is partially or completely disassembled. Corrosion tests to predict degradation usually employs small specimens exposed to accelerat...
