Revista Espacialidades, 2016 A proposta desse artigo é discutir a espacialidade na porção meridional da América portuguesa, com destaque à capitania de São Vicente. Durante o período inicial de conquista e colonização da região, a espacialidade, através das ideias de sertões e fronteiras forma fundamentais para a historiografia sobre a ocupação dessa região.

Fluid Toxicities: Violent Affective Ecologies in Cartagena, Colombia
Antipode, Volume 58, Issue 5, September 2026.ABSTRACT Water is at the centre of climate change emergency concerns in coastal cities. It constitutes here a fluid entry point to investigating the socio‐ecological politics of toxicities for residents dwelling with and against contaminated waters in Cartagena, Colombia's urban extensions.

Extração por fluido supercrítico [PDF]
Revista Brasileira de Farmacognosia, 1996 The present study evaluated the antimicrobial activity of the 70% hydroalcoholic extract from Leonurus sibiricus l., Lamiaceae. The antimicrobial activity was determined throught the minimum inhibitory concentration (MIC). The extract of Leonurus sibiricus l. was active against Candida albicans, Staphylococcus aureus and Pseudomonas aeruginosa.

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed

Advanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Solución de un problema cotidiano mediante un análisis termodinámico
Revista Educación, 2005 Cuando un globo de feria se escapa libremente a la atmósfera queda sometido a una serie de factores físicos y químicos que al final van a limitar la altura máxima que alcanzará. En un primer paso y utilizando el principio de Arquímedes se calcula la
