Etnografia é, etnografia não é
Ilha Revista de Antropologia, 2017 Usando uma noção de "digital" como uma de suas metáforas principais, uma versão do termo que se apoia na discussão de Kara Keeling sobre o "humanismo digital", este texto argumenta que há algo sobre as não-linearidades que definem a diferença da digitalidade que pode nos ajudar a pensar sobre recalibragens no próprio projeto etnográfico.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Skin wound injuries are often accompanied by bacterial infections and severe inflammation. Especially, M1‐type macrophages at the wound site can trigger a cascade of inflammatory responses, mediating a vicious cycle of inflammation. Meanwhile, hypoxia further exacerbates vascular damage and constriction in the wound microenvironment, thereby ...

Sexo é maldição, ódio é amor [PDF]
Revista Latinoamericana de Psicopatologia Fundamental, 2015 e o amor. Porem nao se trata do amor idealizado, mas sim daquilo que ele comporta de paradoxal, da sua face maldita, obscena e tragica. E no estudo das obras literarias de Nelson Rodrigues, Gregorio de Matos e Fernando Pessoa que este livro demonstra a afirmacao freudiana de que os artistas ja sabiam o que mais tarde a psicana-lise veio revelar: a ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.
