Beyond batch experiments: unveiling the potential of bimetallic carbon xerogels...
Silva, Adriano S.; Roman, Fernanda; Ribeiro, Rui; Garcia, Juan; Gomes, HelderSingle- and bimetallic carbon xerogels were prepared by incorporating iron and iron-cobalt precursors during their synthesis, respectively, and tested in the catalytic wet peroxide oxidation (CWPO) of ibuprofen spiked into a simulated matrix in batch mode. The bimetallic catalyst outperformed single and non-metallic catalyst by 25 and 85% after 360 min of reaction, at mild temperature (30 °C). The best-performi...
NILM techniques for intelligent home energy management and ambient assisted liv...
Ruano, Antonio; Hernandez, Alvaro; Ureña, Jesus; Ruano, Maria; Garcia, JuanThe ongoing deployment of smart meters and different commercial devices has made electricity disaggregation feasible in buildings and households, based on a single measure of the current and, sometimes, of the voltage. Energy disaggregation is intended to separate the total power consumption into specific appliance loads, which can be achieved by applying Non-Intrusive Load Monitoring (NILM) techniques with a m...
Small bowel adenocarcinoma – case report and literature review
Santos, Pedro; Teodoro, Marta; Garcia, Juan; André, Eugénia; Seabra, NélsonThe authors present a theoretical review of small bowel neoplasm based on a case report, of a 49-year-old man, with hypertension and diabetes mellitus, whose diet included the main sources of iron; without any previous surgeries. He presented progressive fatigue, pallor, and reduced exercise capacity, without changing bowel habits, apparent hematic stool losses or recent weight loss. Laboratory studies showed: ...
Gastrointestinal stromal tumor – case report
Sousa, Elisabete; Araújo, Rosário; Garcia, Juan; Rua, AbelThe authors present a clinical case report, of a 73 year-old female patient, with hypochromic, microcytic anaemia and serum iron deficiency, of two years duration. The out-patient colonoscopic and upper gastro-duodenal endoscopic studies were inconclusive. She presented with a decline in general status, asthenia and anorexia of two months duration, as well as dark stools and tachycardia, four days before hospit...
