Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms
Darras, Kevin F. A.; Rountree, Rodney A.; Van Wilgenburg, Steven L.; Cord, Anna F.; Pitz, Frederik; Chen, Youfang; Dong, Lijun; Rocquencourt, AgnèsAim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. ...
Removal of mercury by silica-supported ionic liquids: efficiency and ecotoxicol...
Viana, Thainara; Almeida, Raquel; Figueira, Paula; Rocha, Luciana; Neves, Márcia; Freitas, Rosa; Freire, Mara; Henriques, Bruno; Pereira, EduardaAnthropogenic impacts have affected the coastal environment and contributed to its contamination. Mercury (Hg) is widespread in nature and has been shown to be toxic in even the smallest amounts, negatively affecting not only the marine ecosystem but also the entire trophic chain due to its biomagnification. Mercury ranks third on the Agency for Toxic Substances and Diseases Registry (ATSDR) priority list and i...
Affordable Futures Past: Rethinking Contemporary Housing Production in Portugal...
Lameira, Gisela; Rocha, Luciana; Ramos, Rui Jorge GarciaThis article focuses on a specific term associated with the scientific, theoretical, and academic discourse on housing architecture in Portugal. Over the last 100 years, the term “affordable” has frequently been used in the vocabulary of urban housing in Portugal, being linked to other words commonly used in housing construction, such as económica (economical), barata (cheap/inexpensive/low-cost), pobre (poor),...
Cultural Appropriation in the United States
Rocha, LucianaThis work was carried out in the context of the curricular unit of Intercultural Studies, taught by Dr. Clara Sarmento, which aims to learn and make known a little more about the phenomenon of cultural appropriation. It was used as a study focus the situation of the United States of America, in particular the case of the Afro-American culture and the North-American Indian culture. Consolidating all the knowledg...
Capitalismo, racismo e violência policial no Brasil
Rocha, LucianaPartindo do princípio de que o sistema capitalista traz no seu cerne a violência, os fundamentos da escravidão e o racismo, o objetivo nesta dissertação é identificar, na formação histórica do Brasil, os elementos originalmente constitutivos do capitalismo, entender se – e de que forma – esses fatores se relacionam com o fenômeno da violência policial no Brasil e compreender como a doutrina positivista influenc...
Optimizing microwave-assisted production of waste-based activated carbons for t...
Sousa, Érika; Rocha, Luciana; Jaria, Guilaine; Gil, Maria V.; Otero, Marta; Esteves, Valdemar; Calisto, VâniaThis work aimed at the microwave-assisted production of activated carbon (AC) from primary paper mill sludge (PS) for the adsorption of antibiotics from water. Production conditions, namely pyrolysis temperature, pyrolysis time and activating agent (KOH):PS ratio, were optimized as a function of product yield, specific surface area (SBET), total organic carbon (TOC) content and adsorptive removal percentage of ...
Supported ionic liquids for the removal of pharmaceuticals from aqueous solutions
Neves, Márcia; Gonçalves, Maria João; Rocha, Beatriz; Lobo-Sousa, Guilherme; Bernardo, Sandra; Rocha, Luciana; Almeida, Hugo; Freire, Mara GThe presence of organic pollutants has been shown to have adverse effects on humans and the environment. Mainly due to their large worldwide consumption, active pharmaceutical ingredients (APIs) were already found in a wide variety of environmental aqueous samples, in concentrations ranging from ng/L to µg/L. Therefore, the treatment of water contaminated with these compounds is extremely important. Ionic liqui...
