1. Estimativas locais para complexos elíticos
Neste trabalho, estendemos algumas estimativas L1 provadas por Bourgain-Brezis no caso do complexo de de Rham em RN para o contexto local de estimativas L1 para complexos elíticos, a saber, aqueles associados a uma estrutura involutiva elítica gerada por uma família de campos vetoriais suaves e linearmente independentes. Em particular, obtemos uma versão

2. The dynamics of structural deformations of immobilized single light-harvesting complexes
Single assemblies of the intact light-harvesting complex LH2 from Rhodopseudomonas acidophila were bound to mica surfaces at 300 K and examined by observing their fluorescence after polarized light excitation. The complexes are generally not cylindrically symmetric. They act like elliptic absorbers, indicating that the high symmetry found in crystals of LH2

3. Intercellular junctions of the hen parathyroid gland. A freeze-fracture study.
The fine structure of the intercellular junctions of the hen parathyroid gland was studied using freeze-fracture replicas and thin sections. In the conventional thin sections, desmosomes, intermediate junctions (maculae adherentes) and gap junctions were observed, and in the lanthanum-fixed sections, tight junctions (maculae occludentes) were demonstrated as
